Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling feeding device for a seedling planting machine, and a seedling box (including a seedling placing plate) in which seedlings are emptied by feeding the seedling onto a seedling placing table. Is intended to be sent back to the ridge.

[0002]

2. Description of the Related Art Many large-sized seedling planting machines capable of transplanting multiple seedlings in one step have been proposed to provide a seedling feeding device for feeding the ridge seedlings to the vicinity of the seedling table of the seedling planting device. ..

[0003]

By the way, the conventional seedling feeding device can send the ridge seedlings to the vicinity of the seedling mounting table, but it is necessary to send the empty box from which the seedlings have been taken out back to the ridges. I couldn't. The present invention makes this possible by skillfully using the front and back of one belt conveyor.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a seedling planting device 2 is mounted behind a traveling vehicle body 1 and seedlings of ridges 9 are placed on a seedling placing table 3 of the seedling planting device 2. A seedling feeding device 6 for feeding to the vicinity is provided on the traveling vehicle body 1 so that its end approaches the ridge 9. The seedling feeding device 6 has a ridge 9 on the upper surface thereof.
A seedling supply in a seedling planting machine, which is provided with a belt conveyor 19 for sending the seedling box 20 from the seedling mounting table 3 side to the ridge 9 while sending the seedling box 20 whose seedling is empty on the back side from the seedling mounting table 3 side. The device.

[0005]

Since the present invention is configured as described above, the operator can put a plurality of seedlings on the ridge 9 together with the seedling box 20 into the seedling feeding device 6.
The ridges 9 are placed in order on the end of the belt conveyor 19 which is rotating. Since these seedlings are sent by the belt conveyor 19 and approach the seedling placing table 3, at this approaching position, only the seedlings are taken out from the seedling box 20, and the seedling box 20 in which the seedlings are empty is removed by the belt conveyor 19. Put it on the back side of. Then, the empty seedling box 20 is sent back to the ridge by the belt conveyor 19.

[0006]

[Effect] As described above, according to the present invention, the seedling box 20 that has been emptied by taking out the seedlings near the seedling mounting table 3 is sent back to the ridges by the belt conveyor. It is rational because the labor required for is unnecessary. In addition, since the empty box 20 is sent back, the back side of the belt conveyor 19 for sending seedlings is used, so that it can be made compact.

[0007]

Embodiments of the present invention will be described below. Figure 1
As described above, the riding type seedling planting machine is configured by mounting the seedling planting device 2 after the traveling vehicle body 1. The seedling planting device 2 includes a seedling mounting table 3 that tilts forward and moves to the left and right. The seedling mounting table 3 allows six mat seedlings each having a size of 60 cm × 30 cm to be mounted side by side. It's done.

A seedling receiving plate 4 having an L-shaped cross section is provided on the seedling mounting table 3 thereof.
It is provided at the lower end of the mat and supports the lower end of the mat seedling. Six sets of the seedling planting rods 5 are provided side by side behind the seedling placing table 3 so that the tip of the planting rod 5 turns vertically in an elliptical orbit when viewed from the side. The respective seedling planting rods 5 swivel from the top to the bottom of the respective outlets provided on the seedling receiving plate 4, and are pushed out from the seedling mounting table 3 onto the seedling supporting plate 4 to be transferred to the seedling mounting table. The bottom edge of the mat seedling that moves left and right along with 3 is cut left and right one by one, and transplanted to the mud surface.

A seedling supply device 6 is provided on the traveling vehicle body 1 in a horizontally long position in front of the seedling mounting table 3. That is, the machine frame 7 is
The right end is attached to the receiving frame 27 on the right side of the traveling vehicle body 1 so as to rotate around the axis 8 in the front-rear direction, and the left end protrudes largely leftward from the traveling vehicle body 1 to bring the traveling vehicle body 1 closer to the ridge 9 of the paddy field. At this time, it is located on the ridge 9.

A base 10 projects rearward from the right side of the machine frame 7, a motor 11 is mounted thereon, and a gear 12 rotated by the motor 11 is driven by a drive shaft 13 supported on the right side of the machine frame 7.
It meshes with the gear 14 of the. The driven shaft 15 is provided on the left side of the machine frame 7. Two drive control wheels 16 and two driven control wheels 17 are provided on the front and rear sides of the drive shaft 13 and the driven drive shaft 15, respectively, and a large number of protrusions 18a and 18b are vertically arranged on each of the left and right control wheels 16 and 17. The belt 18 provided around the belt conveyor 19 is wound around the belt 18. Therefore,
When the operator puts the seedling on the ridge 9 together with the seedling box 20 on the belt 18 at its left end, the belt 18 is rotated by the motor 11 in the counterclockwise direction in FIG. Are sent in front of the seedling stand 3. The seedling sent by another worker is taken out from the seedling box 20 and placed on the seedling mounting table 3, and the seedling box 20 with the empty seedling is placed on the return side of the belt 18 (upward side of the rear surface). When it is placed on, the protrusion 18b sends it back to above the ridge 9.

A guide 21 is provided on the left side of the machine frame 7 on the return side of the belt 18, and is provided with an oblique guide surface so that the empty seedling box 20 which has been sent back is sent to the left side. It is configured to be pushed forward by being pushed. A receiving box 22 is provided at the drop position of the seedling box 20. As shown in FIGS. 1 and 3, the automatic switch 23 is provided on the right side of the belt 18, and the seedling box 2 containing seedlings is provided.
When 0 is sent, the electric circuit for the motor 11 becomes O.
It is provided so as to perform FF. Further, operation switches 25 and 26 are provided near the seat 24 and on the left side of the machine casing 7, respectively, and are arranged in series. Therefore, the operator activates the motor 11 with the operation switch 26 to rotate the belt 18, and places six seedlings in the seedling box 20 in order on the left end of the belt conveyor 19 on the ridge 9. Then, when the first seedling box 20 is sent to the right and reaches a predetermined position, the automatic switch 23 turns off the electric circuit and the rotation of the motor 11 is stopped. Here, the operator moves to the traveling vehicle body 1, turns off the circuit with the operation switch 25, then takes out the seedlings on the belt conveyor 19 from the respective seedling boxes 20 and puts them side by side on the seedling placing table 3, and the seedlings are placed. The empty seedling box 20 is placed on the return side under the belt conveyor 19, and the operation switch 25 is turned off first.
To turn on the circuit. Then, the motor 11 is activated, the belt conveyor 19 is rotated, and the empty seedling box 20 is sent back into the receiving box 22 on the ridge 9. The seat 24 in FIG. 1 is shown with its backrest tilted forward.

As shown in FIGS. 1 and 2, the locking body 26 having the locking groove 26a is fixed to the right of the machine frame 7, and the traveling vehicle body 1
A lever 28 rotatably provided on the side receiving frame 27 engages with the locking groove 26a. Therefore, the receiving frame 26 can be rotated around the right shaft 8 to be locked at a desired position, and the seedling feeding device 6 can be folded upward during rice planting work or storage to prevent an obstacle. ing.
