  The base plate 15 is made of a rectangular plate having a length approximately equal to the width of the planting ridge, and a portion where each of the perforated portions 10 is located is opened in a circular shape. The base plate 15 is formed on the moving frame 100 of the bulb planting machine A described later. The cushioning members 17 and 17 provided at both ends in the longitudinal direction are attached to be stretchable. In this embodiment, each buffer member 17 is a so-called panda graph. That is, each buffer member 17 is attached to the vertically moving frame 100 by the left and right folding links 17a that can be freely rotated by the intermediate rotating portion 17b. The left and right folding links 17a are pivotally attached at two positions in the width direction of the base plate 15 at the lower ends, and are attached to the vertically moving frame 100 via the attachment portions 17c at the upper ends. In the vicinity of the portion 17b, in this embodiment, a spring 17d is provided that urges the left and right folding links 17a to approach each other.

  Each perforated portion 10 is provided in the opening of the base plate 15 and operates a plurality of claws 11 that break the multi-film MF while moving horizontally from the center NC of the planned planting position N to the peripheral NO direction, and each claw 11.

  Next, the operation of the punching device 1 for opening a planting hole in the multi-film according to the embodiment of the present invention will be described.

  With respect to the main frame 101 on which the mounting plate 3 for the bulb G of the bulb planting machine A such as garlic is provided, the punching device 1 also descends according to the vertical movement frame 100 that is lowered by the frame vertical movement means 7. This descending distance is determined and instructed by a planting holder vertical movement control means (not shown) of a bulb planting machine A such as garlic which will be described later. At this time, each nail | claw 11 of the perforated part 10 is located in the planting center of the vertical part 11b, and has a thick bar shape assembled in contact with each other. As the vertically moving frame 100 descends, the bottom circular opening 19 of the base plate 15 comes into contact with the top surface of the multi-film MF but further descends a certain distance.

  After the vertically moving frame 100 is lowered and the base plate 15 comes into contact with the upper surface of the multi-film, when the vertically moving frame 100 is further lowered and pressed, the cushioning member 17 that is a panda graph shortens the interval, and the vertical of the connecting link 18 The kite 18a descends. At this time, the vertical portions 11b of the four claws 11 gathered at the center of the perforated portion 10 pierce the multifilm MF from the upper surface and break it.

  In the buffer member 17, the intermediate rotating portion 17 b of the left and right folding links 17 a is folded outwardly against the urging force of the spring 17 d to reduce the distance between the vertically moving frame 100 and the base plate 15.

  As the vertical rod 18a of the connecting link 18 descends, the curved rod 18b rotates and the horizontal rod 18c moves in a certain horizontal direction by a certain distance. At one end of the horizontal rod 18c, the claw operating ring 14 is rotated in a certain direction, and all the claw operating rings 14 are similarly rotated in the same direction by the interlocking rod 16.

However, the claw operating arm 12 is connected to the claw operating pin 13 by the oblong hole 12b with which the claw operating pin 13 is engaged. The distance from end to end in the circle does not work. In the meantime, the vertical part 11b of the nail | claw 11 pierces and inserts the multifilm MF of planting position center NC from the upper surface reliably. After this time difference, the claw actuating pin 13 pushes one end of the oblong hole 12b, so that the claw actuating arm 12 pivots about the arm pivoting part 12a and the vertical part 11b of each claw 11 is shown in FIG. In this way, the multi-film MF is broken by moving in the direction of the outer periphery NO of the planned planting positions while drawing a slightly arc-shaped locus NL, and a hole for planting is formed in the multi-film MF.

  After the planting hole N is formed, when the vertical movement frame 100 starts to rise by the instruction of the planting holder vertical movement control means (not shown), the buffer member 17 is released when the pressing force from the movement frame 100 is released. The gap between the left and right folding links 17a is narrowed by the biasing force of the spring 17d to widen the gap between the vertically moving frame 100 and the base plate 15.

  As the distance between the vertically moving frame 100 and the base plate 15 increases, the vertical rod 18a of the connecting link 18 rises, the curved rod 18b rotates, and the horizontal rod 18c moves in the opposite horizontal direction by a certain distance. The claw actuating ring 14 is also rotated in a certain reverse direction, and all the claw actuating rings 14 are similarly rotated in the reverse direction by the interlocking rod 16. As the claw actuating ring 14 is rotated in the opposite direction, each claw 11 is also brought into contact with the center by an arcuate trajectory. This operation is repeated.

As the crank arm 85 rotates, the frame 100 including the planting holder 4 and the pressing shaft 90 is connected to the crank arm 85 by the connecting lot 86 and can move back and forth. This frame back-and-forth moving means 8 synchronizes the traveling device 2 so that the reverse speed of the planting holder 4, the pressing shaft 90, etc. is substantially the same as the forward speed of the traveling device 2. The electromagnetic clutch 81 is turned ON / OFF to adjust a time lag with each operating mechanism.

  A bulb mounting plate 3, bulb loading means 5, and a longitudinally moving frame 103 are attached to a main frame 101 of a bulb planting machine A such as garlic of the present invention. The forward / backward moving frame 103 is attached to a rail provided in the horizontal direction of the main frame 101. A pinion 70 of the frame vertical movement means 7 and a vertical movement frame 100 are attached to the vertical movement frame 103 so as to be movable up and down. The vertically moving frame 100 is fixed to the rack 71 of the frame vertically moving means 7 and engages with two vertical poles 103a of the vertically moving frame 103 to move up and down. A perforating device 1 is attached to the lower part of the vertically moving frame 100, and a reversing frame 102 is attached so as to be able to turn around the horizontal axis 60.

  The traveling device 2 is provided with multi-film upper surface position detecting means 200 and planting holder vertical movement control means (not shown). The multi-film upper surface position detecting means 200 has a multi-film upper surface abutting portion that traces the upper surface of the multi-film MF at one end and is provided on the support frame 204 of the planting holder 4 so as to be vertically rotatable by the rotating portion 203. A sensor arm 201 having 202 is included. The multi-film upper surface contact portion 202 is made of a roller.

  The planting holder vertical movement control means (not shown) transmits an angle signal detected by the change in the rotation angle of the rotation part 203 between the sensor arm 201 and the support frame 204 to the vertical movement means 7. The position control of the vertical movement of the planting holder 4 is controlled based on the upper surface of the multi-film MF.

  Each drive unit described above is a motor in this embodiment, but a cylinder device may be used.

  Next, the operation of the bulb planting machine A such as garlic provided in the traveling device 2 according to the embodiment of the present invention will be described with reference to FIGS. 6 and 8 to 15.

  Two workers normally sit on the worker's seat 22 of the traveling device 2, and one of the operators operates the driving operation unit 21 of the traveling device 2 and steers it. The engine 23 is actuated by the operation of the driving operation unit 21 to rotate the crawler traveling unit 20 via the transmission 24 and the axle 27 to cause the traveling device 2 to travel. The traveling device 2 causes the crawler traveling unit 20 to travel between the ridges so as to straddle the ridge M.

  In the bulb planting machine A such as garlic, the bulb G is placed on the placement portion 31 of the bulb placement plate 3 in FIG. 8, and the push rod 50 of the bulb loading means 5 is located above the placement portion 31. The bulb holding part 40 of the planting holder 4 is located below the placement part 31. When there are two workers, the bulb G is inserted into the placement portion 31 with the bulbs G placed in front of the work sheet 22 two by two. At this time, the rotation of the bulb mounting plate 3 is stopped.

  Next, the raising / lowering drive part 52 of the bulb | ball loading means 5 act | operates, and the raising / lowering drive part 52 descends the raising / lowering stick | rod 53. FIG. When the raising / lowering drive unit 52 starts to descend, the connected push rod 50 is also lowered (FIG. 9), and the bulb G of the planting holder 4 where the push rod 50 is placed on the placement unit 31 is located below. It pushes and loads to the holding part 40 (FIG. 10).

  After the push rod 50 is lowered to the position where the bulb holding part 40 of the planting holder 4 is loaded with the bulb G, the raising / lowering drive unit 52 immediately starts raising the raising / lowering rod 53 and stops the push rod 50 at the original position (FIG. 11). ).

  When the push rod 50 is positioned above the placement portion 31, the circular plate-like body 30 of the bulb placement plate 3 rotates 90 degrees, and the next placement portion 31 on which the bulb G is placed is moved to the push rod 50. Position it in the lower position. As the circular plate 30 of the bulb mounting plate 3 rotates, the frame upside down means 6 and the frame back and forth moving means 8 start to operate, and the up and down moving frame 100 to which the planting holder 4 is attached moves in the forward direction. While starting to move, it starts to flip up and down around the horizontal axis 60. Then, the vertically moving frame 100 to which the planting holder 4 is attached moves to the foremost position, the planting holder 4 is turned upside down by 180 degrees, and the bulb holding part 40 faces downward. Faces upward (FIG. 12).

  At this time, the frame back-and-forth moving means 8 is connected to the transmission 24 that drives the axle 27 of the crawler traveling unit 20, and transmits the movement synchronized with the rotational speed of the axle 27 to the crank arm 85. The forward / backward moving frame 103 is moved back and forth in the traveling direction by moving the connecting lot 86 forward and backward. The electromagnetic clutch 81 is disengaged when it is desired to stop the movement of the crank arm 85.

  Next, as shown in FIG. 8, the multi-film upper surface abutment portion 202 made of a roller of the multi-film upper surface position detecting means 200 traces the upper surface of the multi-film MF, so that the multi-film MF upper surface and the crawler traveling unit 20 travel. Even when a height difference with the intercostal surface occurs, the angle of the support frame 204 and the rotating portion 203 of the sensor arm 201 changes with the upper surface of the multi-film MF as a reference, and the planting holder upper and lower portions correspond to the angle change. A movement control means (not shown) is operated to operate the holder vertical movement device 7 and adjust its descending distance. As the holder vertical movement device 7 descends, the position of the bulb holding portion 40 of the planting holder 4 descends to a height close to the upper surface of the multifilm MF and stops.

  When the vertical movement frame 100 is lowered by the frame vertical movement means 7, the lower surface of the punching device 1 presses the multi-film MF. By this pressing, the vertical portion 11b of the claw 11 of the punching device 1 breaks the multi-film MF from the upper surface, and the further pressing force activates the connecting link 17 of the punching device 1 to rotate the claw operating ring 14. The nail actuating arm 12 is actuated via the nail actuating pin 13 to open a bulb planting hole in the multi-film MF covering the bulb planting basket M. Each punching portion 10 of the punching device 1 pierces from the upper surface the multifilm MF at the center where the four rod-shaped claws 11 are to be planted, and then moves the multifilm MF from the center NC toward the peripheral NO direction. Break.

  Next, the shaft driving portion 91 of the bulb planting means 9 is operated to lower the center position of the outer peripheral holding portion 41 of the planting holder 4 from the base portion toward the distal end portion. The push-out shaft 90 pushes the bulb G loaded in the bulb holding part 40 of the planting holder 4 from the bulb holding part 40 and the outer circumference holding part 41 and pushes it into the soil at the planting position to plant at a certain depth (see FIG. 14). ).

  During the time when the push-out shaft 90 of the bulb planting means 9 is lowered and raised, the frame back-and-forth moving means 8 is operated to move the planting holder 4 and the pressing shaft 90 backward at substantially the same speed as the traveling speed of the traveling device 2. Therefore, the extrusion shaft 90 and the planting holder 4 can be moved up and down by stopping the back and forth movement at the bulb planting position.

  As shown in FIG. 15, the push-out shaft 90 descends to a certain depth, and the bulb G is planted in the soil. Flip 180 degrees upside down. The planting holder 4 attached to the reversal frame 102 is turned upside down by 180 degrees so that the bulb holding part 40 faces upward. At the same time, the frame vertical movement means 7 operates to raise the vertical movement frame 100, raise the reversal frame 102 and the planting holder 4, and stop the backward movement of the forward / backward movement frame 103 by the frame forward / backward movement means 8. In this state, the members and devices return to the positions shown in FIG.

  With this operation as one planting cycle, garlic is planted sequentially as the traveling device 2 travels.

  The present invention is highly applicable to a field of a large planting area for the purpose of planting bulbs such as garlic, particularly for harvesting bulbs such as professional garlic.
