Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sub soiling digger plow working machine, and more particularly, to a sub soiling digger plow working machine capable of simultaneously excavating a subsoil and reversing a soil layer. .
[0002]
[Prior art]
As is well known, surplus water treatment is important in the field that is the basis of agricultural production because it belongs to the hot and rainy region of Japan. In order to improve the environment of the field, not only draining the soil but also soil It is necessary to dry.
For this reason, the reverse plowing method using the bottom plow working machine adopted in the mechanized agriculture in Europe and the United States has been adopted in Japan, but its diffusion has not been promoted slowly in Japan's agriculture, which is originally intensive agriculture. is the current situation.
Especially in the south of Honshu, it is close to the subtropical climate, so reverse cultivation should be adopted to promote the drying of the soil, but the farming scale of many farmers in Honshu is smaller than that in Hokkaido, Bottom plow work machines have not yet become widespread.
[0003]
Moreover, the subsoiler work machine is employ | adopted as a work machine which accelerates | stimulates the drainage of field soil. This is because a slit-like deep groove is formed in the soil, and a part of the hardened layer or subsoil layer is crushed, and surplus water from the field is guided to the subsoil layer below the hardened layer in this slit-like space. It is what.
However, the subsoiler work machine only forms a slit-like space in the soil of the field, so to speak, it is one of partial deep plowing, but since it has no plowing function, the field surface can be dried. However, it does not have the function of actively drying the soil in a deep position under the topsoil of the field.
In addition, a number of excavation work machines and sub-soil digger plow work machines previously proposed by the applicant of the present application have excavation claws as a unit and are attached to the work machine frame to excavate and cultivate the field. It is.
Specific examples include JP-A-9-322601 and JP-A-2000-270602.
[0004]
[Problems to be solved by the invention]
Each of the work machines according to the above-described prior art is configured such that the tilling claw units are arranged in a horizontal row in the work progress direction on the work machine frame constituting the work machine. These work machines are also very effective in promoting drainage and drying of field soil, but work traction resistance is large due to the work of submerging the excavation reversing blade in a deep position, and it is used by most farmers in Japan. That tractor cannot do that work. If work is done dare, the work machine which made the number of excavation reversing claw units single can only be used. This is not suitable for agricultural management that has been enlarged due to the expansion of field plots.
[0005]
In addition, a large working machine is required to efficiently dry a large-scale farm, but considering the particularity of Japanese agriculture, the necessity of a working machine that can be applied to a small tractor is Some are quite expensive.
In other words, it is necessary to use a larger working machine and tractor in consideration of efficient work to prepare the field environment for crop growth, but considering the special characteristics of Japanese agriculture, it is used with a relatively small tractor. If it is not a working machine that can be used, it is difficult to spread, and the relationship between the two is a trade-off.
Further, the working machine is suitable for excavation work of subsoil, but is not suitable for performing burying work such as foreign substances existing on the field surface, for example, weeds and post-harvest stumps.
[0006]
Therefore, the present invention cultivates exhausted subsoil with poor nutrient permeability and low nutrient content on the field surface, and further, disperses impurities scattered on the field surface by plowing the soil layer. It is buried so that it can be used to circulate organic matter.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention firstly provides a chisel at the lower end of a sub-soiling digger plow working machine configured by attaching excavation reversing and releasing claws to a working machine frame constituting the working machine. A beam having an upper end attached to the work machine frame, an excavation inversion board unit attached to the beam, and a bottom unit arranged in parallel to the excavation inversion board unit. The excavation reversing board unit has at least a excavation curved surface portion continuous with the chisel surface and an inverted curved surface portion formed at an upper position of the excavation curved surface portion. The bottom unit has at least an earthing plate portion, and the direction of reversal of the earthing plate portion is the excavation inversion board. The position in the height direction with respect to the excavation reversal board unit in the same direction as the reversal curved surface portion of the knit is configured such that the lowermost end portion thereof is located within the range of the front excavation curved surface portion. is there.
[0008]
As a result, the exhausted subsoil is cultivated and regenerated on the field surface, and the soil layer is cultivated and inverted to bury buried impurities scattered on the field surface. Can be reproduced.
[0009]
In addition, the excavation reversing board unit has an excavation reversing plate on the work surface side, a metal bracket plate on the back surface, and this bracket plate is attached to the beam with bolts or the like. In addition, it is convenient for excavation reversal board unit replacement work due to wear and the like.
[0010]
In addition, since the bottom unit is constructed by attaching a shear along the lower edge of the earth plate, it is possible to reliably reverse the soil layer and to effectively use organic matter. Can do.
[0011]
In addition, the bottom unit is configured so that it can be fixed by moving vertically along the beam of the excavation reversing board unit. You can choose.
[0012]
Further, since the inverted curved surface of the bottom unit is formed continuously with the curved surface of the bottom unit excavation reversal plate, the reversal of the reverse clay can be smoothly and reliably performed.
[0013]
In addition, the excavation reversing board unit is provided with a soil discharge plate unit at a side position on the soil reversal side, and this soil discharge plate unit is configured to be attached to the beam. The spread soil can be diffused over a wide area on the field surface and can contribute to the regeneration of the subsoil.
[0014]
Further, since the earth removal board unit is configured to be fixed by moving in the vertical direction along the beam of the excavation reversing board unit, the earth discharging board unit is discharged over a wide area of the field surface. The soil can be expanded and the amount (thickness) of the soil to be expanded can be arbitrarily selected.
[0015]

A hole is provided so that the posture of the hitch seat 13 with respect to the distal end portion 13B can be fixed by selecting one of the bolt holes 13X and 13Y formed in the distal end portion 13B of the center mast 11. This is to select the hitch point of the upper link, and is used in the case of work conditions or movement of the work implement between fields.
[0017]
An attachment seat arm 15 for attaching the excavation reversing board unit 20 to be described below is attached to the work implement frame 10, and the attachment seat arm 15 is fastened to the work implement frame 10. Extending from the flange 16. The flange 16 has a “ku” shape that surrounds a half of the outer periphery of the work machine frame 11, and the mounting seat arm 15 extends from the flange 16 toward the rear in the working direction. Is formed of things. Both ends of the flanges 16 penetrate the flanges 16 by "ku" -shaped bolts 17 surrounding the remaining half of the work machine frame 11 with respect to the flanges, and the flanges that are substantially half the circumference of the work machine frame 10 are tightened with nuts. Fastened with and installed.
[0018]
One mounting seat arm 15 is provided on the left and right in the working width direction around the center mast 11. In other words, two excavation reversing board units 20 can be installed. It is a working machine equipped with so-called two-claw equipment.
An end portion of the mounting seat arm 15 is a mounting seat arm 15A, and an upper end portion 21U of the beam 21 constituting the excavation reversing board unit 20 can be mounted by a bolt 15B drilled up and down.
[0019]
The beam 21 has a front edge (front edge in the work progress direction) of the upper end 21U that is linear in a side view, and an intermediate part 21C and a lower end 21S projecting in the work progress direction continuously from the front edge. It is a curved line that draws an arc between the two. The chisel 22 is attached to the lower end portion 21S via a bed 22A, and the excavation work is performed at the head position during the excavation work.
[0020]
The beam 21 is attached with a plate-like bracket plate 23 having an arc shape along the front edge of the upper end portion 21U and the intermediate portion 21C. The rear side of the bracket plate 23 is spaced at an appropriate interval. There are a plurality of pairs of attached mounting plate pieces 23A, 23A, and these mounting plate pieces 23A are attached to the beam 21 with bolts in a state of sandwiching the beam 21 from both side surfaces. The bracket plate 23 is formed of a metal plate or the like, and has a function of reinforcing an excavation reversal plate, which will be described later, and a function of facilitating attachment to the beam 21. Further, the bracket plate 23 is an upper end portion of the beam 21. It has a shape extending up to near 21 U and extending along the curved surface of the excavation reversing plate 25.
[0021]
More specifically, several pairs of mounting plate pieces 23A, 23A are fixed to the rear surface of the bracket plate 23 at an appropriate interval by welding or the like so as to hold the beam 21 therebetween. The pieces 23A and 23A are other than those in which the plate pieces are arranged in parallel, the cross-sectional shape is L-shaped, one side is assigned to the back side of the bracket plate 23, and the other side is assigned to one side of the beam 21, and is reversed by a bolt or the like. The bracket plate 23 can be attached to the beam 21 using a U-shaped attachment plate piece.
[0022]
The excavation reversal plate 25 is attached to the bracket plate 23 along the front surface in the work progressing direction, and is reinforced from the back side of the excavation reversal plate 25. The lower end 25S of the excavation reversing plate 25 is continuous with the curved surface continuous with the surface of the chisel 22, and the intermediate portion 25C extends upward in an arc to form an excavation curved surface 25K. Further, the upper end portion 25U extends above the uppermost end portion of the bracket plate 23 to form a discharge curved surface 25Y for urging discharge of excavated soil to the field surface. Further, in order to release the excavated soil rising along the discharge curved surface to the side in the working direction, the upper end 25U of the excavation reversing plate 25 is combined with the bracket plate 23 or the upper end 25U of the excavation reversing plate 25. Only in the left and right direction toward the work progress direction, twist is gradually applied to form the inverted curved surface portion 25X. The reverse curved surface portion 25X is also formed on the bracket plate 23. However, since the excavation reverse plate 25 is higher than the bracket plate 23, in other words, since the length from the lower end is longer, The state is such that the excavation reversing plate 25 is twisted more.
[0023]
The excavation reversing plate 25 is made of plastics such as propylene or nylon, which has less soil adhesion in the field, low work resistance, and low wear due to friction. In addition to the plastics, the excavation reversing plate 25 is made of stainless steel or steel depending on the nature of the soil, so that there is less adhesion of soil, so the material can be selected according to the soil quality of the field used. Is done. At this time, when the same metal as the bracket plate 23 is used, the bracket plate 23 itself may be used as the excavation reversing claw. In other words, the bracket plate 23 can also be used as the excavation reversal plate 25.
[0024]
Further, a bottom unit 30 is attached to the beam 21 at an adjacent position in the vertical middle position 25C of the excavation reversing plate 25. The bottom unit 30 has a shear 31 and an excavation function having a reversing function. The plate 32 and further a bed 33 for supporting them are constituted. This bed 33 has a front bed portion 33A located on the back side of the shear 31 and a front bed portion 33A extending along the lower edge of the earth plate 32 and a front edge portion thereof having an acute angle when there is no shear. The crossing and rear end portion is constituted by a side bed portion 33B extending rearward in the work progressing direction, and a pressure receiving plate 33C positioned on the back surface of the earthing plate 32.
The side bed portion 33B has a shape and function similar to the land side of the bottom plow, and a plurality of bolt holes 21N are arranged vertically on the beam 21 corresponding to the bolt holes drilled in the side bed portion 33B. It is worn in. When the posture of the bottom unit 30 is not stable during work, a plurality of fixing points are provided by providing the bolt holes 21N along the traveling direction of the beam 21.
[0025]
A set of bolt holes 21N, 21N,... Aligned along the vertical direction is selected and bolt holes 33N, 33N drilled in the side bed 33B of the bottom unit 30 are combined to be bolted to the beam 21. To do. At this time, the working depth of the bottom unit 30 can be arbitrarily selected by selecting the mounting position. The bottom unit 30 is attached to the reversing side of the reversing curved surface portion 25X of the excavation reversing plate 25.
[0026]
Further, by disposing and attaching the bottom unit 30 on both sides of the excavation reversing plate 25, the soil formation layers on both sides around the excavation reversing board unit 20 can be reversed not only in one direction but also in both directions. This embodiment is shown as a front view in FIG. 5, and each bottom unit 30 </ b> L, R of right inversion and left inversion is arranged on the left and right of the excavation inversion plate 25. In this case, the excavation inversion plate 25 has an excavation width. Narrow excavation reversing claws are used, the reversing function at the upper end is not necessary, and the reversing curved surface portion 25X is omitted.
[0027]
Further, in order to fix the bottom unit 30 to the beam 21 so as to give a reversing function in the left and right direction, the side bed portions 33B and 33B provided in the left and right bottom portions are positioned on the left and right sides of the beam 21 so as to be bolted to each other Install by.
[0028]
Next, an operation using the plastic ring digger plow working machine 100 according to the present invention will be described. First, the work machine 100 is attached to a tractor by a three-point link mechanism and is used for work. The actual work machine trajectory is deeply excavated by excavation action by the excavation reversing plate 25 as shown in FIG. A groove G is formed, and a shallow inversion groove g having a soil layer as a work object adjacent to the groove G is formed by a tilling inversion action by the bottom unit 30.
In other words, the deep groove G is formed by reversing excavation by the excavation reversal plate 25, and at this time, the subsoil is excavated by the excavation curved surface portion 25K and moved in the discharge direction toward the upper end 25U, The excavated soil is reversed sideways by the inverted curved surface portion 25X formed at the upper end portion 25U. The shallow groove g is formed by excavating the soil layer portion by the shear 31 of the bottom unit 30 and then reversing by the earthing plate 32 and releasing it to the adjacent field surface.
[0029]
At this time, if weeds or stumps are present on the field surface, the reversing action of the bottom unit 30 ensures that the debris is buried under the reversing soil by reversing the gravel. it can.
Further, a deep groove G is formed by the excavation reversing plate 25, and the excavated soil is released on the upper surface of the soil formation layer, and with this release operation, the soil formation layer is inverted by the bottom unit 30. It is possible to regenerate the subsoil by mixing the subsoil with less nutrients and the soil containing excessive fertilization and the remaining fertilizer by long-term fertilization.
[0030]
In the case where the excavation reversing plate 25 has a relatively thin shape and does not have the reversing curved surface portion 25X, the working machine having the bottom units 30 on both sides of the excavation reversing plate 25 is either left or right. The subsoil to be released is reversed by the bottom units 30R and 30L.
[0031]
Further, the bottom unit 30 is moved along the beam 21 in the vertical direction so that the excavation depth can be freely selected. Therefore, according to the field structure, for example, according to the amount of impurities existing in the field. To select the inversion depth.
In FIG. 8, a bolt hole 21N existing at an appropriate height is selected from the group of bolt holes 21N formed in the beam 21, and the bottom unit 30 is attached to that position. Thereby, the excavation depth by a bottom unit, etc. can be selected according to the field condition.
[0032]
In the above description, the bottom unit 30 provided with the share 31 has been described. However, when the bottom unit excavates a relatively shallow portion of the soil formation layer, the excavation load is relatively small. The lower edge of the plate 32 may also be used as a shear. In other words, the excavation function can be expected even if the lower edge portion of the earth plate 32 has a sheer shape.
[0033]
Further, as shown in FIGS. 7, 8, 9, and 10, in the configuration in which the bottom unit 30 is attached to the beam 21 constituting the excavation inversion board unit 20, excavation by the excavation inversion board unit 20 is performed. Subsequent to the reversal action, the bottom unit reversal and the excavation action can reliably form the shallow reversal g-groove to reliably revers the excavated gravel. If the bottom unit is deeply plowed, the load at the time of reversal increases, so as shown in FIG. 11, the side bed 33 is set to a high dimension in the height direction to increase the fixed area with the beam. To withstand the workload. Also in this case, the reversing direction of the bottom unit 30 and the reversing direction of the excavation reversing board unit 20 are determined in the same direction.
[0034]
Further, what is shown in FIG. 12 is one in which the excavation reversal board unit 20 and the bottom unit 30 are further integrated. The reverse curved surface portion 25X of the excavation reversal plate 25 constituting the excavation reversal board unit 20 and the bottom unit 30 are shown. When the reversing excavated soil by the excavation reversing board unit 20 moves with the reversing curved surface of the earthing plate 31 as a continuous curved surface, the soil is continuously taken over by the reversing curved surface of the earthing plate 31 of the bottom unit 30. And can be surely released to the side of the working direction.
[0035]
13 and FIG. 14 shows a bottom unit that is deformed from a mold board in a so-called mold plow. In FIG. 13, the bottom unit 30 is close to the one equipped only on one side, and is shown in FIG. The thing corresponds to the thing with which the bottom unit was equipped on both right and left sides. In this case, the excavation reversing unit 20 is reversed in one direction, but the excavation reversing board unit 20 can be reversed on both sides.
[0036]
In this embodiment, the mounting structure of the bracket plate 23 and the beam 21 is the same as that of the above-described embodiment, and the description thereof is omitted. The bracket 23 is also provided on the back surface of the earth plate 31 in the bottom unit 30 and is provided with a reinforcing function for the earth plate 31. It is possible to fix a plastic plate material on the surface of the earth generating plate 31 to reduce friction with the soil and to prevent adhesion of the soil. The material is preferably the same material as the excavation reversing plate 25.
[0037]
In the above description, the bottom unit 30 is positioned on both sides of the excavation reversal board unit 20 to form the shallow reversal groove g adjacent to the deep excavation groove G. Therefore, the working machine 100 will be described as an embodiment of the present invention that is further developed. First, the earth excavation board unit 40 having a leveling function can be located on either one of the left and right sides of the excavation reversing board unit 20 or on both sides. The earth removing plate unit 40 has a function of excavating the field surface by work movement, a function of leveling debris existing on the field surface, and can move the collected soil to the side. It has a function and has the function of flattening the field surface. 13, 14, 15, and 16, the configuration includes a plate-shaped soil discharge board 41, a digging blade 42 formed on the lower edge thereof, and a bracket attached to the back side of the soil discharge board 41. 43. The bracket 43 is L-shaped in plan view, and has a portion 43A attached to the back side of the earth removing substrate 41 and a flange portion 43B attached to the beam 21, and each has a bolt hole 43X. Is worn.
[0038]
The front surface 41A of the soil removal substrate 41 has a shape in which the central portion in the height direction is depressed in the work progressing direction, and can accommodate the soil when the soil on the field surface is excavated. The curved surface is not so important, and the front surface 41A may be standing upright, or the upper end edge may be inclined rearward in the traveling direction (the phantom line portion in FIG. 12). In this case, the angle at which the portion 43A to which the bracket 43 is attached and the flange portion 43B intersect is an acute angle.
[0039]
Furthermore, when the earth removal board unit 40 is attached to the beam 21, the edge 41X on the opposite side of the earth removal board 41, in other words, the outer edge 41X in the working width direction is inclined backward. Therefore, the soil excavated and excavated by the excavation reversing board unit 20 is widely diffused by the excavated plate unit 40 with an appropriate thickness.
Therefore, it is possible to promote the regeneration of the subsoil by spreading the subsoil widely on the field surface, and to select the diffusion range of the subsoil by selectively adjusting the height of the soil removal plate unit 40 with respect to the field surface. Is possible.
[0040]
The earthing plate unit 40 is attached to the beam 21 by selecting the bolt hole 21N of the beam 21 and attaching the flange portion 43B of the bracket 43 to the beam 21 with a bolt. At this time, by selecting the height from the bolt holes 21N arranged in the height direction, it is possible to select the height of the soil surface unit surface of the soil removal board unit 40 itself.
[0041]
The height position adjustment of the earth discharging plate unit 40 can be performed in the same manner as the bottom unit 30 in the above embodiment, and the excavation depth or the amount of collected dirt is selected by selecting the mounting position with respect to the beam 21. can do. For example, when spreading debris existing on the field surface thinly, a thin diffusion layer is formed by reducing the space between the soil discharging plate unit 40 and the field surface.
In addition, by increasing the excavation depth by the earth removal substrate 41, the gravel soil on the surface can be collected and moved to the side while excavating the surface.
[0042]
In the above description, the excavation reversing board unit 20 is attached to only one side of the excavation reversing board unit 20, but the excavation reversing board unit 20 can be configured to be attached to both sides of the excavation reversing board unit 20. In this case, since the excavated and discharged soil by the excavation reversing board unit 20 is discharged to one side in the work progress direction, the one side of the excavated soil unit 40 from which the excavated discharged soil is not discharged does not function. In the working machine configured with the board unit 20 attached, it is effective when the excavated and discharged soil by the adjacent excavation reversing board units 20 is widely diffused on the field surface.
[0043]

In addition, since the bottom unit is constructed by attaching a shear along the lower edge of the earth plate, the bottom unit is improved in excavation ability at a deeper position, and the uncultivated land is inverted. Can be possible.
[0051]
Further, since the bottom unit is configured to be fixed by moving vertically along the beam of the excavation reversal board unit, the excavation reversal depth with respect to excavation reversal of uncultivated land is characterized. The height can be selected according to the environment of the field, and can contribute to the maintenance of the field environment in relation to the soil.
[0052]
Further, the excavation reversing board unit is provided with a soil discharge plate unit at the side position on the soil reversal side, and this soil discharge plate unit is configured to be attached to the beam. Convenient for spreading on the field surface of soil.
