Description

  The present invention relates to a composite tillage device capable of performing other farming operations together with tillage operations in a field. More specifically, the present invention relates to a composite tillage device to which a tilling device is used as a main device and a farming device capable of performing other farming operations is added.

  2. Description of the Related Art Conventionally, for example, a composite tiller that combines a rotary tiller and a chisel tiller has been proposed. Such a combined type tillage device can plow the field efficiently because the rotary tillage work can be performed simultaneously while deep plowing with the chisel type tillage device. By the way, in recent years, it has been demanded to reduce the required energy for the farm work apparatus as well as the apparatus in other industrial fields, and it is desired to reduce the energy for this type of combined farm work apparatus as well. It has become.

  Therefore, for example, Patent Document 1 proposes a composite tillage device 100 that reduces the required energy during tillage as shown in FIG. FIG. 8A shows the tilling device 100 with the vertical direction as the traveling direction and the horizontal direction as the width direction of the device. Moreover, the same (B) has shown the cultivation apparatus 100 seen to the arrow X direction in (A). This combined tiller 100 has a rotary tiller 110 and a chisel tiller 120 arranged in parallel in the vertical direction, and most of the working parts of the chisel tiller 120 are the rotational radius of the rotary pawl 111 of the rotary tiller 110 or It arrange | positions so that it may be located vertically downward. This combined-type tillage device 100 has been developed so as to be able to perform tilling work while reducing energy, particularly when roughing uncultivated soil.

JP 2003-125604 A

  As shown in FIG. 8 (A), in the compound type tillage device 100 of Patent Document 1, the straight blade portion 121 of the chisel-type tilling device 120 is disposed at a substantially intermediate position of the rotary claw 111 disposed at a predetermined interval. A wing 122 is provided at the tip of the straight blade 121. Such a structure is suitable for the work of roughing the uncultivated soil as described above, but is not suitable for the fine soil cultivation. Therefore, when fine soil plowing is performed, it is necessary to change to a chisel device in which the action portion is in a suitable position. However, since the chisel-type tilling device 120 is assembled and fixed in the rotary tilling device 110, the chisel-type tilling device 120 cannot be easily removed in the composite tillage device 100 of Patent Document 1.

  Therefore, it is necessary for the composite tiller 100 of Patent Document 1 to replace the chisel-type tiller 120 with another type over a long period of time or to prepare a tiller for fine soil cultivation separately. . Therefore, there is a problem that the work takes a long time and the cost increases. In addition, farm work on the field includes other work such as sowing work and fertilization work in addition to the plowing work. Replacing a dedicated device with a traveling machine such as a tractor every time a different farm work is performed is troublesome and wastes time. However, there are few compound plowing devices that can perform conventional plowing work and a plurality of other farming works at the same time, and the work to be performed is limited.

In addition, this composite-type tillage device has a rotary tiller of a predetermined width as a main body device, similarly to the conventional tiller shown in FIG. Below, like FIG.8 (B), the structure which looked at the compound type tillage apparatus from the side is shown and demonstrated.

  FIG. 1 and FIG. 2 are views showing a composite tiller 1 in which a chisel-type tiller 20 </ b> A is attached to a rotary tiller 10. FIG. 1A shows a configuration of the composite tillage device 1 viewed from the side, and FIG. 1B shows a rotary claw 11 of the rotary tiller 10 and a straight blade portion 21A of the chisel tiller 20A. It shows about the arrangement relationship. FIG. 2 is a view showing a state where the chisel type tillage device 20 </ b> A is set on the rotary tiller 10 to form the composite tillage device 1.

  The composite tillage device 1 is mounted or towed by a traveling machine body such as a tractor (not shown) and performs the tilling work while proceeding in the arrow Y direction shown in FIG. The rotary tiller 10 is a main unit of the composite tiller 1, and the chisel type tiller 20 </ b> A is attached to the rotary tiller 10, so that rotary tilling and chiseling can be performed. The rotary tiller 10 includes a pair of frames 15 at both ends in the width direction, and a rotary claw shaft 12 is supported between the frames 15. Rotary claws 11 are arranged on the rotary claw shaft 12 at a predetermined interval in the width direction (see FIG. 8A).

  Support plates 16 extend rearward from the respective frames 15 arranged on both sides of the apparatus. As shown in FIG. 2, the support plate 16 is formed to support the chisel-type tilling device 20A. Two concave portions 17 and 18 are formed as receiving portions at predetermined positions of the support plate 16.

  Next, the chisel type tillage device 20A will be described. The chisel-type tilling device 20A has a pair of side plates 25 in the width direction. The pair of side plates 25 are arranged with a slightly narrower interval than the interval between the frames 15 on the rotary tiller 10 side. The side plates 25 are fixed to both end faces of the square pipes 26 arranged in the width direction. The base end portion of the chisel direct blade portion 21 </ b> A is fixed to the square pipe 26 with a nut 28 using a U-shaped bolt 27. A plurality of straight blade portions are similarly fixed to the square pipe 26 at predetermined intervals in the width direction. Further, a small square pipe 29 is disposed between the side plates 25 in the same manner as the square pipe 26 for reinforcement.

  Projections 31 and 32 projecting outward in the width direction are provided on the surface of the side plate 25 as engaging portions. These protrusions 31 and 32 are formed to engage with the recesses 17 and 18 of the rotary tiller 10 described above. That is, as shown in FIG. 2, by setting the protrusions 31 and 32 protruding outward from the side plate 25 of the chisel-type tilling device 20A to be engaged with the recesses 17 and 18 of the rotary tilling device 10, A composite tiller 1 shown in FIG.

  As described above, the two concave portions 17 and 18 are formed at predetermined positions of the frame 15 on the rotary tiller 10 side. By engaging the protrusions 31 and 32 of the chisel-type tilling device 20A with the recesses 17 and 18, the chisel-type tilling device 20A can be accurately set at a predetermined position of the rotary tilling device 10 on the main body side. As shown in FIG. 2, a lock claw 19 is provided on the recess 18 side. The lock claw 19 rotates around the support shaft 19a. The lock claw 19 functions as a detachment preventing means and is pressed from above so that the protrusion 32 supported by the recess 18 does not detach.

  The chisel-type tilling device 20 </ b> A is a type provided with a rear cover device 40. The rear cover device 40 has a rear cover 41 provided so as to cover the rear side, and a biasing force by a spring 42 is applied to the rear end portion of the rear cover 41. The rear cover 41 has a predetermined space inside. Such a chisel type tillage device 20A with a rear cover device can arrange the soil after tilling uniformly.

  As described above, in the composite tillage device 1, the chisel-type tilling device 20A is detachably attached to the rear side of the rotary tilling device 10. In particular, the protrusions 31 and 32 provided on the side plate 25 of the chisel type tiller 20A are engaged with the recesses 17 and 18 of the support plate 16 provided on the rotary tiller 10 side. Therefore, the chisel-type tilling device 20A can be easily attached and detached without requiring time for the replacement work as in the conventional apparatus. If other farm work devices are provided with projections similar to those of the chisel type tillage device 20A, they can be easily set on the rotary tiller 10 and desired farm work can be performed simultaneously with the rotary tillage.

  Furthermore, the arrangement position of the straight blade portion 21A of the chisel type tillage device 20A is different from the conventional one. This point will be described with reference to FIG. The composite tiller 1 can easily set a chisel-type tiller. Therefore, if a plurality of different chisel-type tilling devices are prepared, chisel-type tilling devices according to the purpose can be set and used.

  Therefore, as in the conventional device shown in FIG. 8, by preparing in advance a chisel-type tilling device in which the straight blade portion is arranged between the rotary claws and vertically below the rotary claws, similarly, uncultivated soil Tillage work that roughens the surface. By the way, if the straight blade portion of the chisel is arranged between the rotary claws as shown in FIG. 8, the soil plowed by the rotary claws hits the straight blade portion and is recut, so that the soil can be made fine. In addition, since the soil hitting the straight blade portion is pushed forward and cultivated by the rotary claws, the soil can be made fine in this respect. On the other hand, since the soil is in a state of being carried around as described above, energy efficiency is lowered. Therefore, FIG. 1 (B) shows an example in which the straight blade portion is arranged so as to suppress energy consumption more reliably without making the soil too fine when performing roughing. In the arrangement shown in FIG. 1B, the straight blade portion 21 </ b> A is arranged so as to face the base end of the rotary claw 11, so that it does not move around as described above. Therefore, it is possible to suppress roughening of the soil more than necessary, increase energy efficiency, and perform roughing tillage work.

  Next, with reference to FIG.3 and FIG.4, the case where the different type chisel type tillage apparatus 20B is attached to the rotary tillage apparatus 10 is demonstrated. FIG. 3A is a view showing the composite tiller 1 when the chisel-type tiller 20B is attached to the rotary tiller 10. Moreover, the same (B) is the figure shown about the arrangement | positioning relationship of the rotary nail | claw 11 of the rotary tiller 10, and the straight blade part 21B of the chisel type tiller 20B. FIG. 4 is a diagram illustrating a state in which the chisel-type tilling device 20B is set in the rotary tilling device 10.

  The chisel type tilling device 20B shown here has only the straight blade portion 21B, and no wing 22 is formed unlike the chisel type tilling device 20A. Further, the straight blade portion 21B of the chisel-type tilling device 20B has an action position above the straight blade portion 21A of the chisel-type tilling device 20A, and faces the tip of the rotary claw 11 as shown in FIG. The straight blade portion 21B is disposed on the left side. When such a chisel-type tilling device 20B is set on the rotary tilling device 10, it is possible to efficiently plow on fine soil while suppressing energy consumption.

  As shown in FIG. 4, this chisel-type tilling device 20B is also simple by simply engaging the protrusions 31 and 32 provided on the side plate 25 with the recesses 17 and 18 of the support plate 16 provided on the rotary tilling device 10 side. Can be set. Moreover, this chisel-type tilling device 20B is also a type provided with the rear cover device 40, and the soil after tilling can be arranged uniformly.

  In the above description, the chisel-type tilling devices 20A and 20B in which the rear cover device 40 is integrally provided are illustrated, but the chisel-type tilling device may not include the rear cover device. FIG. 5 shows a chisel-type tilling device 20C, 20D of a type not provided with a rear cover device. (A) is a type obtained by removing the rear cover device from the chisel-type tilling device 20A, and (B) is a type obtained by removing the rear cover device from the chisel-type tilling device 20B. If different types of chisel-type tilling devices are prepared in this way, an optimum chisel-type tilling device can be set on the rotary tilling device 10 to perform necessary tilling work efficiently.

  The farm work device set in the rotary tiller 10 is not limited to the chisel type tiller as described above. Some conventional rotary tillers are provided with a rear cover integrally at the rear, but are difficult to remove. The rear cover can be seen as one of the farm equipment because it arranges the soil after tillage. Further, the size of the inner space is different between the rear cover used when performing normal rotary tilling and the rear cover when performing towing tilling using a chisel. Therefore, it is preferable to prepare a rear cover device as a farm work device that can be attached to and detached from the rotary tiller 10.

  With reference to FIG.6 and FIG.7, the case where the rear cover apparatus 50 is attached to the rotary plowing apparatus 10 is demonstrated. FIG. 6 is a view showing the composite tillage device 1 when the rear cover device 50 is attached to the rotary tiller 10. FIG. 7 is a view showing a state in which the rear cover device 50 is set on the rotary tiller 10.

  A rear cover 41 suitable for rotary tilling is set in the rear cover device 50 shown here. When such a rear cover device 50 is set on the rotary tiller 10, soil can be prepared while plowing energy efficiently. As shown in FIG. 7, the rear cover device 50 can also be easily mounted by engaging the projections 31 and 32 provided on the side plate 25 with the recesses 17 and 18 of the support plate 16 provided on the rotary tiller 10 side.

  Since the combined type tillage device 1 described above can set other farm work devices such as a chisel type tillage device to the rotary tiller 10 serving as a main body device, a plurality of farm work can be performed simultaneously. And since a farm work apparatus can be easily attached or detached with respect to the rotary plowing apparatus 10, it can replace in a short time and does not become an obstacle of farm work. When the composite tillage device 1 is used, the work can be efficiently performed when the tilling work is different, for example, the paddy field is roughed and then the fine soil tillage work is performed. Specifically, when the paddy field is roughened in the form shown in FIG. 1, and then the fine soil cultivation is carried out in the form shown in FIG. 3, the farm work can be performed efficiently while suppressing the required energy.

  In the said Example, although the some chisel type tillage apparatus and the rear cover apparatus were illustrated as an agricultural work apparatus, it does not restrict to this. For example, a sowing device, a fertilizer, a soil disinfecting device, and the like that are set in the rotary tiller 10 may be prepared so that other farm work can be performed by the combined tiller 1.

  The preferred embodiment of the present invention has been described in detail above. However, the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims.
