Description

  The present invention relates to a vertical seeding machine that is mounted on a rear portion of a rotary tiller that is towed by a towing vehicle such as a tractor or a management machine, and more specifically, a vertical seeding machine including a vertical molding machine and a seeder. It is related with the position adjustment mechanism of a seeding machine for performing by.

Conventionally, in a vertical seeding machine, a seeding operation for forming a seed bed such as soybeans and a seeding operation for sending seeds onto the seeding bed are continuously performed. After cultivating the soil with the device's tilling claws, the vertical plate of the vertical molding machine advances to level the ground, and the vertical edge has a sharp edge between multiple flat plates arranged side by side. However, it progresses while biting into the soft ground cultivated by the tilling claws, and both side plates of the erecting device are exposed to the cultivated soil and lifted to the side to form ridges. In the subsequent sowing operation, the soaking machine's grooving device proceeds on the formed ridge to form a sowing groove, and seeds fed from the feeding device driven by the drive wheel are discharged into the sowing groove. After that, the covering body progresses and covers the soil, and further, a pressure wheel rolls over the sowing portion so as to press the seeded portion.
However, the ridges that have been leveled and raised by the above-mentioned erection work are fragile, and the surface is greatly uneven due to soil conditions and tillage conditions, the towing vehicle body moves up and down, or the sowing machine. If the height or posture of the machine is not appropriate, the groover, covering body, pressure wheel, etc. will penetrate deeply and the heel may break, or conversely, the grounding of the drive wheel to the heel surface will be insufficient and the feeding device will be In some cases, the plant did not work, or the sowing machine was inclined with respect to the surface of the culm, so that the seeding depth was uneven and normal growth of the crops was hindered.
Therefore, in the conventional seeding simultaneous seeding machine, a technique for extending a supporting rod behind the toolbar horizontally installed on the rotary tiller and suspending the seeding device on the supporting rod via a parallel link mechanism (for example, Patent Documents). 1) and a technique (for example, Patent Document 2) in which a front end of a support rod is externally fitted to a toolbar standing on a rotary tiller so that the support rod can be moved up and down, and a seeder is fixed to the rear end of the support rod. Yes.

  By using any of the conventional techniques, the height of the sowing machine is adjusted so that the driving wheel is grounded on the surface of the cocoon but driven so that the cocoon does not break. It is possible to keep the seeding depth uniform by keeping it almost horizontal, but the front and rear positions of the seeder cannot be changed freely, especially not independently from the vertical molding machine. It was. For this reason, seeds cannot be accurately sown on the finished culm, and the environment suitable for growth such as sunlight, root respiration and drainage cannot be given to the seeds. There was a problem of causing a drop. This is because, in the above-mentioned erection operation, the position where the cocoon is formed changes greatly in the front-rear direction depending on conditions such as the hardness, particle size, and moisture content of the soil. For example, the soil is soft and easily flows. In some cases, since the soil flows backward at high speed, the ridge is formed behind the normal. Conversely, when the soil is hard and difficult to flow, the movement of the soil is slowed and the ridge is formed forward than usual. Is done. For this reason, it is necessary to adjust the front and rear positions of the seeder so that the seeding position is always on the seedling immediately after completion.

The bevel gears 89 and 90 and the rotating shaft 88 are transmitted to the feeding rotary body 87, and the feeding rotary body 87 is rotationally driven.

  A plurality of unillustrated transport holes are perforated in the feeding rotary body 87, and when a part of the large number of seeds 91 flowing down from the seed hopper 83 enters the transport holes of the rotating feed rotary body 87, It is conveyed to the feeding port 86a formed in the storage part 86, and is sowed between the grooving disks 52 through the sowing guide pipe 56 communicated with the feeding port 86a.

  The entire feeding case 85 is made of a transparent material such as a synthetic resin so that the outer peripheral surface of the feeding rotating body 87 can be seen from the outside from all directions. Furthermore, the outer peripheral surface 87a of the feeding rotating body 87 is divided into a plurality of areas 87b at equal intervals, and at least the area 87b is colored, so that the rotating state of the feeding rotating body 87 in the feeding case 85 can be obtained even from a distance. Can be confirmed at a glance. In addition, you may make it provide the area 87b only in a part of said outer peripheral surface 87a.

  In the present embodiment, the entire feeding case 85 is made of a transparent material, but only a part of the feeding case 85 may be made of a transparent material. Further, when there is a part that shields the feeding rotary body 87 inside the feeding case 85, the feeding case 85 and all or a part of the parts inside the feeding case 85 may be made of a transparent material. Further, a translucent material may be used instead of a completely transparent material. Alternatively, the feeding case 85 is not formed of a transparent material or a semi-transparent material, but an opening is provided in a portion of the feeding case 85 that does not affect the driving unit and the seed conveyance on the side surface or the front and back surfaces, and the feeding rotation inside. It can also comprise so that a part of body 87 can be visually observed.

  In any case, it is sufficient that the whole or a part of the feeding rotary body 87 is visible from the outside of the feeding case 85, and the feeding case 85 is not limited to the above structure. Furthermore, although the feeding device of the present embodiment is of the eye plate type, it may be of a roll type such as a slide roll as long as it can confirm the feeding of the seed by the rotation of the feeding rotating body.

  That is, it comprises a feeding case 85 and a feeding rotating body 87 that feeds and feeds the seeds by a fixed amount by rotating the seed 91 in a feeding hole formed on the outer surface and housed in the feeding case 85.

The whole or a part of the feeding rotary body 87 can be visually confirmed, and a non-uniform color is provided in the rotation direction on the outer peripheral surface 87a of the visible part of the feeding rotary body 87, whereby the movement of the color is controlled. By looking from the outside of the feeding case 85, the rotation state of the feeding rotary body 87 can be clearly confirmed, and it is easily and reliably confirmed whether or not the seeds are accurately dropped. It is possible. In addition, since the feeding case 85 is made of a transparent material or a semi-transparent material, it is only necessary to color the feeding rotating body 87, so that it is not necessary to separately provide expensive parts such as a sensor, and the feeding rotating body 87 can be manufactured at low cost. The rotation status can be confirmed.

Next, the position adjusting mechanism 43 according to the present invention will be described with reference to FIGS. 1 to 3, 5, and 6. FIG.
The position adjustment mechanism 43 includes a front / rear position adjustment mechanism 64 and a height / posture adjustment mechanism 65. As shown in FIGS. 1, 3, and 5, in the front-rear position adjusting mechanism 64, two guide bodies 66 are disposed at the substantially right and left central portions of the first toolbar 24. A U-shaped locking portion 66a opened downward in a side view is formed at the lower portion of the guide body 66, and a plurality of screws 68 are fixed vertically on the front and rear surfaces of the locking portion 66a. After the engaging portion 66a is fitted to the first tool bar 24 from above, the screws 68 are inserted into the fixing holes 67a at the four corners opened in the fixing plate 67 so that the fixing plate 67 is attached to the first tool bar 24. 24, the guide body 66 can be fixed to the first tool bar 24 so that the left and right positions thereof can be adjusted by screwing the nut 69 onto the screw 68 from below.

  In the upper part of the guide body 66, square pipe-shaped guide portions 66b facing in the front-rear direction are formed, and the left and right guide portions 66b have left and right sides of the U-shaped moving body 70 opened forward in plan view. The sliding portions 70a and 70a are inserted so that the movable body 70 can slide back and forth along the guide portions 66b and 66b. The rear ends of the sliding portions 70a and 70a are connected by a connecting portion 70b, and the height / posture adjusting mechanism 65 is provided at a substantially right and left central portion of the connecting portion 70b extending in the left-right direction. It is supposed to be installed.

  Further, the upper and lower surfaces of the left and right guide portions 66b are respectively provided with pin holes 66c at the same position in plan view, and the upper and lower surfaces of the left and right sliding portions 70a are also at the same position in plan view. Pin holes 70c are respectively opened, and a plurality of pin holes 70c and 70c are formed in the front-rear direction at intervals. After the moving body 70 is slid in the front-rear direction so that the pin hole 70c of the moving body 70 overlaps the pin hole 66c of the guide body 66, the locking pin 71 is inserted into the pin holes 66c, 66c, 70c, 70c. By doing so, the front-rear position of the moving body 70 with respect to the guide body 66 can be fixed at a predetermined position.

  The moving body 70 may be configured such that its position can be adjusted steplessly. For example, the moving body after being continuously stepped by screwing a bolt into a screw hole provided in the guide portion 66b of the guide body 66 and pressing the tip of the bolt against the outer surface of the sliding portion 70a. 70 can be fixed at a predetermined position, which enables fine adjustment of the fixed position with a simple structure. Moreover, it is good also as a structure which can adjust the front-back position of the moving body 70 in a stepless manner by sliding the moving body 70 by gear drive. For example, the sliding portion 70a of the moving body 70 is provided with an outward rack over the longitudinal direction of the sliding portion 70a, and the pinion engaged with the rack is fixed to the support shaft of the handle for adjusting the front-rear position. The gears are engaged. When the handle is turned, the moving body 70 is slid stepwise in the front-rear direction. When the handle operation is stopped, the moving body 70 also stops at a predetermined position. After stopping, the moving body 70 is securely fixed via a plurality of gears by locking the handle with a hook or the like.

  In the height / posture adjustment mechanism 65, a U-shaped hitch 72 that opens forward in a side view is fitted in the left and right center of the connecting portion 70 b of the moving body 70, and a hitch pin 72 a that is inserted vertically. Thus, the hitch 72 is connected to the connecting portion 70b at the rear of the moving body 70. Furthermore, since the play is generated between the moving body 70 and the hitch 72 only by being locked by the hitch pin 72a, the pressing body 72c is pressed by the tightening bolt 72b to eliminate the play between the hitch 72 and the moving body 70. I have to.

  Adjustment frames 73 and 73 are erected upward from the hitch 72, and pivot frames 74 and 74 are pivotally supported on a pivot shaft 73 a provided at the lower rear portion of the adjustment frame 73. The upper portions of the adjustment frames 73 and 73 and the upper portions of the rotation frames 74 and 74 are pivotally supported by pins 75 and 76, respectively, and screw portions 77a of the posture adjustment handle 77 are screwed into the pins 75, By rotating the posture adjustment handle 77, the rotation frames 74 and 74 can be rotated back and forth around the pivot shaft 73a.

  Guide rods 78 and 78 are vertically suspended on both sides of the rear ends of the rotating frames 74 and 74, and a screw rod 79 is pivotally supported between the rear portions of the rotating frames 74 and 74. A height adjustment handle 80 is provided at the upper end of the collar 79, and the lower end of the screw collar 79 is screwed into the bar mounting body 81. On both front sides of the bar mounting body 81, pipes 82 and 82 are fixed in parallel in the vertical direction, and the guide rods 78 and 78 are inserted into the pipes 82 and 82. The height adjusting handle 80 is When rotated, the bar mounting body 81 is moved up and down while being guided by the pipes 82 and 82. A fitting portion 92 is formed at the rear portion of the bar mounting body 81. After the fitting portion 92 is set at the center of the left and right sides of the second toolbar 25, the mounting brackets are put together and the second toolbar is attached with bolts. Can be fixed to 25.

  As a result, when the posture adjusting handle 77 and the height adjusting handle 80 are rotated, the bar attachment body 81 rotates back and forth around the pivot shaft 73a and is lifted and lowered while being guided by the pipes 82 and 82. The posture and height of the bar mounting body 81 with respect to the moving body 70, that is, the posture and height of the second toolbar 25 fixed to the rear portion of the bar mounting body 81 can be freely changed.

  In the above configuration, when the soil is easy to flow and the soil flows backward at a high speed during the erection operation, and the ridge is formed rearward than usual, as shown in FIGS. The seeder 5 is moved backward using the position adjusting mechanism 64. That is, after the left and right locking pins 71 are detached from the guide body 66 fixed to the first tool bar 24, the sliding portions 70a of the movable body 70 are moved along the guide portions 66b and 66b of the guide body 66. 70a is moved backward, and when the seeding position of the seeder 5 is on the formation position of the ridge, the locking pin 71 is inserted into the pin hole 66c of the guide body 66 and the pin hole 70c of the mobile body 70, The connecting part 70b at the rear end of the moving body 70 is changed to an appropriate rear position. Subsequently, the posture adjusting handle 77 of the height / posture adjusting mechanism 65 is rotated to rotate the rotating frame 74 back and forth about the pivot shaft 73a, and the rotating frame 74 with respect to the connecting portion 70b. Further, the height adjusting handle 80 is rotated to raise and lower the bar mounting body 81 with reference to the rotating frame 74, and the height of the bar mounting body 81 relative to the rotating frame 74 is increased. change.

  Conversely, when the soil is difficult to flow and the soil flows backward at a low speed during the erection work and the ridge is formed forward than usual, the front / rear position adjusting mechanism 64 is used as shown in FIG. The seeding machine 5 is moved forward. That is, after the left and right locking pins 71 are removed from the guide body 66 fixed to the first toolbar 24, the sliding portions 70a and 70a of the moving body 70 are moved along the guide portions 66b and 66b of the guide body 66. Is moved forward, and when the seeding position of the seeder 5 comes on the formation position of the cocoon, the locking pin 71 is inserted into the pin hole 66c of the guide body 66 and the pin hole 70c of the movable body 70, and moved. The connecting part 70b at the rear end of the body 70 is changed to an appropriate front position. Thereafter, as in the case of changing to the rear position, using the height / posture adjustment mechanism 65, the front and rear angles of the rotating frame 74 with respect to the connecting portion 70b and the height of the bar mounting body 81 with respect to the rotating frame 74 are used. To change.

  Since the seeder 5 is connected to the bar mounting body 81 via the second tool bar 25, the seeder for the first tool bar 24 is controlled by the front / rear position adjusting mechanism 64 and the height / posture adjusting mechanism 65. The front / rear position, height, and posture of 5 can be freely changed. Moreover, as described above, the vertical molding machine 4 composed of the vertical tool 28, the leveling plate 37 and the like can also freely change the horizontal position / height relative to the first toolbar 24, and the front / rear position adjustment mechanism 64 of the seeder 5 can be changed. The height / posture adjusting mechanism 65 can be adjusted independently of each other.

  That is, the front and rear position and height of the sowing machine 5 with respect to the rotary tiller 2 in the simultaneous sowing machine 3 that is mounted on the rear portion of the rotary tiller 2 and includes the tapping machine 4 and the sowing machine 5. -Since the position adjustment mechanism 43 that can change the posture independently of the above-described vertical molding machine 4 is provided, the front and rear positions of the seeding machine 5 can be freely changed, so that the seeding can be accurately seeded on the finished basket. Thus, the environment suitable for growth such as sunlight, root respiration, drainage, and the like can be given to the seeds, so that the crop yield can be increased and the quality can be improved.

  Further, the position adjustment mechanism 43 includes a height / posture adjustment mechanism 65 and a front / rear position adjustment mechanism 64, and the front / rear position adjustment mechanism 64 includes a guide body 66 provided in the rotary tiller 2 and the guide. A movable body 70 slidable in the front-rear direction along the body 66, and the seeder 5 is attached to the movable body 70 via the height / posture adjusting mechanism 65. 64 can be formed with a simple configuration including the guide body 66 and the moving body 70, and the parts cost of the simultaneous seeding machine 3 can be reduced and maintainability can be improved.

  The position adjustment mechanism according to the present invention is not limited to a simultaneous seeding machine, and so as to continuously perform a plurality of processes, it is important to adjust the front / rear position, height, and posture between the processing machines. It can be applied universally to complex working machines such as simultaneous soil disinfecting machines.
