The seedling box arranging and collecting machine 1 includes a traveling unit 2 at the lower part of the machine body, a loading unit 3 provided above the traveling unit 2, and a seedling box unfolding unit 4 that is long in the left-right direction provided on the rear side of the traveling unit 2. It is prepared for. The loading unit 3 is configured to receive a seedling box stacking cart 5 in which the seedling boxes a are stacked in the vertical direction and load the seedling boxes a. A seedling box take-out device 6 that takes out the seedling box a from the loading unit 3 and supplies the seedling box a to the seedling box unfolding unit 4 is provided on the rear side of the loading unit 3. It is configured to be moved up and down along the rail 10 in the vertical direction via the lifting chain 9 by driving the lifting motor 8. The table 7 is moved up and down to the height of each shelf of the seedling box stacking cart 5 in the loading section 3 and the seedling box a is appropriately drawn out to the table 7 by a drawing tool (not shown). The seedling box is pulled out to the same height as the seedling box mounting surface of the seedling box unfolding section 4, and the seedling boxes are arranged on the left and right by the left and right lateral feed conveyors 11 provided on the mounting table 7. Each of the seedling boxes a is transferred and supplied to the developing unit 4.
[0009]
The traveling unit 2 is configured to cause the aircraft to travel in response to a seedling box arranging operation from the seedling box unfolding unit 4 to the ground by driving the pair of left and right crawlers 12.
Each of the left and right seedling box unfolding sections 4 includes a seedling box mounting frame 13 for transporting and guiding the seedling box a supplied from the seedling box take-out device 6 in the left-right direction, and the seedling box mounting frame 13 serving as the left and right outer ends of the machine body. And a seedling box stopper 14 for restricting the seedling box a from being transferred to the outside of the seedling box mounting frame 13 at the front end of the seedling box mounting frame 13 and the seedling box mounting frame 13. A forward / backward feed conveyor 15 for transferring the seedling box in the rearward direction to the rear side of the seedling box transfer path to be performed, and an idle roller 16 for guiding the transfer of the seedling box in the front / rear direction on the rear side of the front / rear feed conveyor 15. The seedling box mounting frame 13 can place four seedling boxes a in a row in two right and left rows (8 in total) with the longitudinal direction of the seedling box facing in the left-right direction. The outer peripheral surface of the idler roller 16 is made of a material having a high frictional resistance such as rubber so that the seedling box to be supplied onto the ground is difficult to slide. Also, on the lower side of the seedling box unfolding portion 4, a left-right axis provided integrally with the seedling box placement frame 13, the seedling box stopper 14, the front and rear feed conveyor 15 and the idle roller 16 at the front end. A forward / backward tilting cylinder 17 is provided to rotate downward about 17a. Accordingly, the operation of the front / rear tilt cylinder 17 changes the posture of the seedling box unfolding portion 4 between the state where the seedling box placed on the seedling box placement frame 13 or the front / rear feed conveyor 15 is substantially front and rear and the rear end portion. The idle roller 16 is switched to the lowered state after being grounded.
[0010]
Wheels 18 are provided at the ends of the seedling box unfolding section 4 that are the left and right outer ends of the machine body, and the wheels 18 are grounded to stabilize the seedling box unfolding section 4 in an appropriate right and left inclined posture with respect to the ground. It has become. The wheel 18 is an idle wheel, and rotates by following the traveling of the airframe by driving the traveling unit 2 by being grounded.
[0011]
By the way, on the mounting table 7 of the seedling box take-out device 6, similarly to the seedling box unfolding part, the back and forth feed conveyor 15, the idler roller 16 on the rear side of the front and back feed conveyor 15, and the front and rear tilt cylinder 17. The mounting table 7 can mount two seedling boxes a on the left and right sides with a space in the center between the left and right sides.
[0012]
The seedling box unfolding section 4 is connected to and supported by the traveling section 2 via a vertical rotating shaft 19 provided on the traveling section 2 side, and rotates to the front side around the rotating shaft 19. Then, it is positioned on the left and right sides of the traveling unit 2 to reduce the left and right width of the aircraft. In addition, the rotation shaft portion in the vertical direction is configured such that the hole into which the rotation shaft 19 is inserted is a long hole in the left-right direction so that the traveling unit 2 and the seedling box unfolding unit 4 have a backlash. It is connected. Further, the entire seedling box unfolding portion 4 including the front and rear tilt cylinder 17 is configured to be rotatable upward about a left and right rotation shaft (not shown) provided at the front end thereof. A rotation restricting link 20 is connected between the left and right end portions of the traveling portion 2 and the front end portion of each seedling box unfolding portion 4, and the seedling box unfolding portion 4 is moved in the vertical direction by the rotation restricting link 20. The rotation about the rotation shaft 19 is restricted.
[0013]
In order to reduce the lateral width of the airframe by rotating the seedling box unfolding part 4 from the normal working state to the front side, first the connection of the end part on the traveling part 2 side of the rotation restricting link 20 is removed, and the seedling box unfolding part 4 side And the restriction on the rotation of the seedling box unfolding portion 4 around the rotation shaft 19 in the vertical direction is released. And the wire 21 is connected between the upper part of the stacking part 3 and the front end part of the seedling box unfolding part 4 between the center part in the left and right direction, and the seedling box unfolding part 4 is lifted by the wire 21 so Tilt up and down to be higher. At this time, the wheel 18 at the end of the seedling box unfolding portion 4 is in a state of being lifted away from the ground. Note that the seedling box unfolding portion 4 can be lifted in a left-right inclined state by the play (conformity) of the rotation shaft 19 in the vertical direction. Therefore, a cantilever support mechanism that cantilever-supports the seedling box unfolding portion 4 from the machine body in the left-right direction with the wire 21 and the backlash (conformity) of the rotating shaft 19 in the vertical direction is formed. ing. Thereafter, the seedling box unfolding portion 4 is rotated upward about the vertical rotation shaft 19 while rotating the seedling box unfolding portion 4 upward about the horizontal rotation axis, and along the side of the traveling unit 2 to the loading unit 3. The seedling box unfolding part 4 is stored. In addition, it has the structure which can fix the seedling box expansion | deployment part 4 in a retracted state by latching the hook 22 provided in the traveling part 2 to the seedling box mounting frame 13 of the seedling box expansion part 4. Accordingly, the left-right width reducing mechanism that reduces the left-right width by rotating the seedling box unfolding portion 4 inward in the left-right direction in a cantilevered state by the vertical turning shaft 19, the left-right turning shaft, the hook 22, and the like. Is configured. The seedling box development part 4 including the wheels 18 is supported by the wire 21 in a state where the seedling box development part 4 is lifted from the ground also in the entire rotation of the seedling box development part 4 to the retracted state. In order to raise the seedling box development part 4, the above-mentioned configuration is configured to connect the wire 21 to the seedling box development part 4, but the effective length of the wire is set as a configuration in which the wire is always connected to the seedling box development part. It is good also as a structure which changes and lifts a seedling box expansion | deployment part. In order to reduce the left and right width of the aircraft, the above-described configuration is provided with the vertical rotation shaft 19 and the horizontal rotation shaft. However, the horizontal rotation shaft is not provided and the vertical rotation is not provided. It is good also as a structure which reduces the left-right width of a body by only rotating a seedling box expansion | deployment part only by a moving shaft.
[0014]
Next, the operation | work which arrange | positions the seedling box a on the ground in the nursery house A by this seedling box arrangement | sequence collection machine 1 is demonstrated.
First, a seedling box stacking cart 5 in which seedling boxes a on which seedlings have been grown to a predetermined size are stacked in the vertical direction is placed on the loading unit 3 and accommodated. The seedling box stacking cart 5 can be accommodated in the loading unit 3 by pushing the seedling box stacking cart 5 by hand and using a crane or the like. Then, the aircraft is run and carried into the nursery house A from the rear side of the machine body through the doorway e of the nursery house A, and the machine body is driven to the end of the nursery house A on the side opposite to the doorway e. At the time of carrying into the nursery house A, the machine body can be carried into the nursery house A by reducing the lateral width of the machine body with the seedling box unfolding portion 4 in the retracted state. After carrying in the nursery house A, the seedling box unfolding part 4 is brought into a normal working state that becomes longer in the left-right direction.
[0015]
Then, the seedling box a is taken out from the loading section 3 by the seedling box extracting device 6 and transferred to the seedling box expanding section 4, and the left and right seedling box expanding sections 4 and the mounting table 7 of the seedling box extracting apparatus 6 total 20 In the state where the seedling boxes a of 10 sheets (2 rows per 10 rows) are placed, the left and right seedling box unfolding portions 4 and the placement table 7 of the seedling box take-out device 6 are idled by the operation of the front and rear tilt cylinder 17. After the roller 16 is grounded, it is switched to a lowered state, and the machine body is run while driving the front-rear feed conveyor 15 to send the seedling boxes a on the ground and arrange them. The worker sets a seedling box number changeover switch 23 described later to “20 boxes” before starting the seedling box arranging work. Therefore, every time the seedling box extraction device 6 is extracted five times, the seedling box unfolding unit 4 and the mounting table 7 of the seedling box extraction device 6 are switched to the rear-lowering state, and the machine body is caused to travel. Even if the lateral feed conveyor 11 of the seedling box take-out device 6 tries to send the seedling box a to the left and right outside more than necessary, the seedling box a is received by the seedling box stoppers 14 at the left and right outer ends of the seedling box unfolding section 4. The seedling boxes a sent to each can be brought into close contact with each other. Then, after the seedling boxes a are completely sent and arranged on the ground, the seedling box unfolding portion 4 and the mounting table 7 of the seedling box take-out device 6 are returned to a substantially horizontal state, and thereafter, the above-described steps are repeated to raise the seedlings. The seedling boxes a are arranged toward the entrance e of the house A. The operation of each part in the process of arranging the seedling boxes a is sequentially and automatically performed by a controller (not shown) provided in the body.
[0016]
The space between the left and right seedling boxes a on the mounting table 7 of the seedling box take-out device 6 arranges the seedling boxes a with a space in the center between the left and right, and this interval portion arranges the seedling boxes a. The passage r in the seedling house A is used for the seedling management work in the seedling house A after that.
[0017]
In this way, the seedling boxes a are automatically arranged toward the entrance e of the nursery house A, and when the rear end of the aircraft reaches the entrance e, the operator changes the seedling box number switch 23 from “20 boxes” to “ Switch to “16 boxes” and switch the number of seedling boxes a in the left-right direction. Then, every time the seedling box extraction device 6 is extracted four times, the seedling box unfolding unit 4 and the mounting base 7 of the seedling box extraction device 6 are switched to the rear-lowering state, and the mode is switched to the control mode for running the aircraft at a time. A total of 16 seedling boxes a (8 rows per row, 2 rows) are arranged, and the aircraft is driven while the traveling unit 2 and the stacking unit 3 are projected out of the nursery house A from the entrance e of the nursery house A. The seedling box a is arranged to the end of the A entrance / exit e side to complete the seedling box arranging operation. In addition, in the state where 16 seedling boxes a are arranged at a time (8 rows per row, 2 rows), the left and right widths of the left and right central space portions s in the nursery house A where the seedling boxes a are not arranged are widened. This is approximately the same as the lateral width of the traveling unit 2 and the loading unit 3. In addition, the left-right width of the left and right central space s in the nursery house A where the seedling boxes a are not arranged is equal to or wider than the left-right width required for the passage of the pair of left and right crawlers 12 serving as the traveling body of the traveling unit 2 You may set the number of the seedling boxes a arranged so that it may become.
[0018]
In unloading the aircraft from the nursery house A, the aircraft is once moved backward and stored in the nursery house A using the left and right central space s in the nursery house A where the seedling boxes a are not arranged. And the seedling box expansion | deployment part 4 is fixed to a retracted state, is made into an original state, and is carried out from the entrance / exit e of the nursery house A. At this time, since the seedling box unfolding part 4 is lifted from the ground by the cantilever support mechanism, the seedling box unfolding part 4 can be rotated forward in the space above the position where the seedling boxes a are already arranged, Since the seedling boxes a can be arranged on the ground of the rotation area of the seedling box unfolding part 4, a large number of seedling boxes a can be arranged on the ground in the nursery house A, and seedlings can be effectively used in the seedling house A. Box arrangement work can be performed.
[0019]
As another means for reducing the lateral width of the machine body, it is conceivable to simply rotate the seedling box unfolding portion 4 to the left and right inside of the body on the upper side. If it does, the edge part will become high upwards, and since the height of the entrance / exit e of the nursery house A is restrict | limited, there exists a possibility that an aircraft cannot be carried in into the nursery house A. Moreover, there is a concern that the center of gravity of the seedling box unfolding portion 4 is increased, the center of gravity of the entire aircraft is increased, and the aircraft is likely to fall down.
[0020]
In addition, as shown in FIG. 6, the seedling box unfolding portion 4 is rotated to the left and right inside of the airframe on the rear side opposite to the traveling portion 2 and the loading portion 3 as another means for reducing the lateral width of the airframe. It is possible. With this configuration, the seedling box unfolding part 4 can be rotated with a part of the traveling part 2 and the loading part 3 protruding from the entrance / exit e of the nursery house A, so the number of seedling boxes a to be arranged can be switched. It is not necessary to change the left and right widths of the left and right central spaces in the nursery house A where the seedling boxes a are not arranged, and the seedling boxes a can be arranged on the entire surface of the nursery house A leaving the passage r in the nursery house A. However, since the center of gravity of the seedling box unfolding part 4 moves to the rear side away from the traveling part 2 and the loading part 3, the center of gravity of the entire body becomes the rear side, so that the traveling performance of the body deteriorates or the body tends to fall down. There are concerns.
[0021]
In addition, although embodiment of this invention demonstrated the structure which makes an airframe drive | work with the crawler 12, it is good also as a seedling box arrangement | positioning collection | recovery machine which lays a travel rail in the nursery house A and travels on this travel rail. .
