Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for a seedling planting device in which a seedling placing table reciprocates left and right, and prevents the end or collapse of the group seedlings after the seedlings to be transplanted are cut off. It aims to reduce variations in the number of seedlings in each strain and the missing strains during transplantation.

[0002]

2. Description of the Related Art In a seedling planting machine in which a seedling placing table moves back and forth from side to side, the end of a group of seedlings is cut off side by side for each one share. After being cut off, there is no support at its end, so it deforms and tries to move forward to the receiving surface side of the seedling support plate. Due to this deformation, the edges of the group seedlings collapsed, leading to missing strains and variations in the number of seedlings per plant.

[0003] In order to solve this, an attempt was made to provide an elastic steel wire, but the contact with the seedling rod expanded and contracted the spacing, and the supporting force at the end of the seedling was insufficient, resulting in a sufficient effect. I couldn't show it.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a seedling mounting table 5 that is slanted in the front-rear direction and carries a mat-shaped group of seedlings 10 and reciprocates left and right. The seedling support plate 6 that is fixed to the aircraft at the lower exit of the platform 5 and receives the end of the group seedling 10 and the seedling intake 6a of the seedling support plate 6 are passed from the top to the bottom, and the group seedlings 10 thereon are It is provided with a seedling planting rod 7 which is cut off in a lateral direction in sequence, and a supporting brush 20 which is provided horizontally on the seedling mounting table 5 and supports an end of the group seedling 10 on the seedling receiving plate 6 side. The supporting brush 20 is extruded. When the end of the group seedling 10 is approaching the receiving surface 6b of the seedling support plate 6, the hair 20a hanging from above bends and the lower end contacts the end of the seedling 10, and the end of the group seedling 10 is chipped. The elastic force is given so that the lower end returns to that end when it is separated from the receiving surface 6b. It was NaeUe apparatus according to.

[0005]

Since the present invention is configured as described above, the mat-shaped collective seedlings 10 placed on the seedling placing table 5 have their ends projecting from the outlets of the seedling placing table 5 and their projecting ends having seedling receiving plates 6 On top,
It moves back and forth together with this seedling stand 5. here,
Since the end of the seedling planting rod 7 passes from the seedling receiving port 6a of the seedling receiving plate 6 downwards, the lateral movement of the seedling mounting table 5 and this seedling planting rod 7 are performed.
Due to the swirling, the collective seedlings 10 are cut off for each one of the stocks when passing over the seedling taking-in port 6a. That is, group seedling 1
0 is chipped laterally from the edge for each one share, and when the remaining one stock at the lateral edge is chipped off, the entire group seedling 10 is extruded to the receiving surface 6b side of the seedling support plate 6, Subsequently, while laterally moving in the opposite direction, the seedling planting rod 7 is cut off at the seedling taking port 6a in the same manner as described above.

At this time, the lower end of the support brush 20 is provided so as to contact the front surface in front of the group seedling 10, and the end of the group seedling 10 is close to the receiving surface 6b of the seedling receiving plate 6, The support brush 20 bends and adapts due to the elastic force, and at the position where the end is separated from the receiving surface 6b by being cut off by the seedling planting rod 7 as described above, the lower end of the support brush 20 is affected by the elastic force. It returns to the rear side and supports the end.

[0007]

[Effect] As described above, according to the present invention, the group seedling 10
The receiving surface 6 of the seedling receiving plate 6 which is cut off by the seedling planting rod 7 at the end of the
Since the part away from b is supported by the lower end of the support brush 20 so as not to move to the receiving surface 6b side, this part is less likely to be deformed or collapsed, and thus the seedling to be transplanted. There are few missing strains, or the number of seedlings among the strains is small. In particular, in this invention, since the end of the seedling is supported by the support brush 20, the end of the seedling is widely supported and the support is stable, and the support effect is improved as compared with the case where the support rod is made of steel.

Embodiments of the present invention will be described below. Figure 1
As described above, the seedling planting device 2 is connected by the link 3 after the traveling vehicle body 1 to form a seedling planting machine. The seedling planting device 2 includes a gear box 4 in a central portion that receives the power of the traveling vehicle body 1, a forwardly tilted gear box 4, and a seedling mounting table 5 that reciprocates left and right.
The seedling receiving plate 6 fixed to the gear box 4 at the tip of the lower end of the seedling mounting table 5 and the seedling taking-in port 6a provided in the seedling receiving plate 6 are swung so as to pass downward from above. It is composed of a seedling planting rod 7 and a float 8 which is provided below the gear box 4 and slides on a mud surface.

As shown in FIGS. 3 and 4, a small trapezoidal pot 9 is connected to an area of 30 cm × 60 cm, and buds grow from this to form a mat-shaped group seedling 10. It is designed to be placed vertically on the 5. Note that the pots 9 used for paddy rice are smaller than those in the figure, and therefore the number of pots 9 lined up in the front, rear, left, and right is much larger than this.

The seedling receiving plate 6 is provided with an L-shaped cross section, and the inner surface of the lower side is a receiving surface 6b, which is orthogonal to the bottom surface of the seedling mounting table 5. The seedling inlet 6a is cut into a slightly larger area than the pot 9 from the receiving surface 6b side toward the bottom surface side. The seedling mounting table 5 is supported at its lower end by the prismatic portion 6c of the seedling receiving plate 6 and the upper guide portion 11 (FIG. 1) so as to move left and right, and reciprocates left and right under the power of the engine. It is designed to be driven by a moving rod 12. Further, a conveyor belt 13 is provided on the bottom surface of the seedling placing table 5, an arm 16 projects from a shaft 15 of a lower wheel 14 on which the seedling placing table 5 is wound, and when the seedling placing table 5 moves to a lateral end, it rotates. Engaging the roller 18 of the crank 17 and rotating clockwise,
The group seedlings 10 on the conveyor belt 13 are fed to the receiving surface 6b side. In addition, the arm 16 is the roller 1
When it is disengaged from 8, it is returned to its original position by a ratchet and a spring (not shown).

Left and right struts 19 extend upward from the side wall at the lower end of the seedling mounting table 5, and both ends of a horizontally long support brush 20 are fixed to the ends thereof. The support brush 20 is composed of a large number of bristles 20a extending to the vicinity of the bottom surface of the seedling mounting table 5, and the bristles 20a
The lower end of the pot contacts the receiving surface 6b side of each pot 9, and when the pot 9 is pushed to the receiving surface 6b side by the conveyor belt 13, it bends by its elasticity and the seedling planting rod 7 receives the receiving surface 6b. When the pot 9 on the side is cut off, it returns to its original position due to its elasticity and hits the surface of the next row of pots 9 on the receiving surface 6b side, and this pot 9 moves to the receiving surface 6b side by gravity or vibration. It supports to prevent it from moving. It should be noted that the tip of the seedling planting rod 7 invades from the right side (FIG. 2) of the bristles 20a to the left side by the turning, and then the pot 9 together with the seedling is cut off to descend. And
The seedling planting rod 7 is configured as follows. That is,
A part of the gear box 4 extends under the seedling mounting table 5 and extends rearward, and a center of a slightly long rotating case 21 is attached to both sides of the rear end to rotate around a horizontal wheel 22 by the power of the engine. It is like this. A pair of seedling planting rods 7 are attached to both ends of the rotating case 21, and the sun gear fixed to the gear box 4 is engaged with the sun gear fixed to the gear box 4 via an intermediate gear at the center of the rotating case 21. When it rotates counterclockwise, it turns while keeping the same posture, and the tip of the seedling planting rod 7 passes along the track A.

As shown in FIG. 1 and FIG. 2, a grooving device 23 is provided on both sides of each float 8 to form a side-row fertilizer application device through which a fertilizer fed from a hopper 24 is guided by a pipe 25. Further, a grooving device 26 of the deep facility equipment is provided at the rear end of each float 8. The grooving device 26 is configured as follows. That is, FIG.
Further, as shown in FIG. 6, the tip ends of the pair of left and right support plates 27 are attached so as to be rotatable around the vertical axis 28. This support plate 27
Includes a supporting leg portion 27a extending downward from the center, and a pair of disks 29 are rotatably attached to the outside of the supporting leg 27a so that the tips of the discs 29 contact each other on the extension line of the vertical axis 28. The spring 30 is provided between the pair of support plates 27, and when the mud is hard when it is moving leftward in the mud, the spring 30 is compressed by the resistance of the mud. Further, when the mud comes to a soft place from this state, the resistance is reduced and the spring 30 extends. Although not shown in the drawing, the pair of left and right support plates 27 is provided with stoppers, and it is not necessary to say a lot that the opening of the right side by the spring 30 is restricted. Then, the fertilizer fed out from the inside of the hopper 31 on the rear side passes through the hose 32 and the pipe 33 and is sprayed to the rear portion between the left and right disks 29. Therefore, when the left and right disks 29 move forward, a deep groove is formed in the mud. here,
If the mud is hard, the spring 30 will be compressed and the rear end of each disk 29 will move closer, narrowing the groove. When the mud is hard, the created ditch is less likely to collapse, so even if the ditch is narrow, the sprayed fertilizer reaches the bottom of the ditch. On the contrary, when the mud is soft, the spring 30 pushes and opens the rear end of the disk 29 to widen the width of the groove formed. If the mud is soft, the groove is likely to collapse, and if it is narrow, the fertilizer may collapse until it reaches the bottom and the spraying position may become shallow.

Further, as shown in FIG. 7, a wire 35 which is pulled by the turning operation of the lever 34 is provided, and the left and right support plates 27 are brought closer by this operation, or the wire 35 is loosened to open the support plate 27. As a result, the pair of disks 29
The width of the groove formed by can be adjusted. This lever 3
4 may be used in combination with the lever of the sensitivity adjusting device of the drive device for moving the seedling planting device up and down (interlocking configuration).
