Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for transplanting seedlings with soil for field work.

Conventionally, as a transplanting device for field work for transplanting seedlings of tomatoes, cabbage, cauliflower, tobacco, etc., into the field, there are known transplanting devices for seedlings with soil-attached blocks and those for pulled-out seedlings. This study was conducted using seedlings (hereinafter referred to as seedlings with soil).

With conventional beak-type transplanters, when the upper end of the cylindrical part of the beak-type transplanter comes into contact with the lower part of the seedling box when attempting to transplant, the seedlings with soil do not move as planned;
Sometimes I would fail. That is, in the conventional device, when the beak-type transplant device is moved upward by a crank motion and just comes into contact with the bottom surface of the seedling box,
At the right time, the seedlings were pushed down from above using a drop-off stick, but with the conventional method, the beak-type planting device descends immediately when it reaches top dead center, so it only needs to be planted at top dead center. It was difficult to get the timing right, and sometimes we ended up failing.

In addition, conventional beak-type planting devices rose until they directly touched the bottom surface of the seedling box and then descended until they penetrated into the field, making it impossible to plant quickly due to the long range of movement. .

The present invention solves this problem by installing a seedling box in which a large number of square holes are arranged vertically and horizontally on a vehicle that runs on engine power. A beak-type planting device is installed near the box and below the seedling box, and between the seedling box and the beak-type planting device, one seedling with soil is pushed out from the back side of the seedling box. A device for transplanting soiled seedlings for field work, which is equipped with a rotary transfer member that fits together, rotates, and drops above the beak-type planting device at the lower position, and a beak at the bottom end of the seedling box and the beak at the top dead center. A rotating shaft is provided between the type planting device and the rotating shaft, which is inclined so as to lie on the bisector of both, and the higher generating line of the rotating axis is horizontal and the lower generating line is vertical. The configuration of the device described above is such that the bottom of a certain pyramid is provided with a guide wall that is perpendicular to the generatrix of the pyramid, so that there is no need to take timing and it can be planted quickly. It is.

To explain with the drawings, 1 is a traveling vehicle body, 2 is an engine attached to the front end of the traveling vehicle body 1, 3 is a front wheel, 4 is a rear wheel, and 5 is a steering wheel for driving. A planting section 6 is provided at the rear of the traveling vehicle body 1. A seedling box 7 is placed horizontally in the planting section 6.
As shown in FIG. 2, the seedling box 7 has a large number of square holes 8 arranged vertically and horizontally, and is made of synthetic resin. The square hole 8 of the seedling box 7 is filled with a bed guard 9, and the seedling 1 with soil is placed inside.
0 is formed. The seedling box 7 is provided vertically or slightly inclined, and is slidable in a direction perpendicular to the traveling direction of the traveling vehicle body 1. Seedling box 7 is
The support arm 13 attached to the lead cam shaft 12 provided in the transmission case 11 intermittently slides in the left and right direction through each square hole by eight minutes.
An extrusion rod 1 is installed on the lower side of the square hole 8 in the bottom row of the seedling box 7.
4 is pivoted 15. 16 is an arm projecting upward from the shaft attachment 15, 17 is a rod, and 18 is an arm, which are attached to the output shaft 19 of the transmission case 11. Figure 2 shows L-shaped link 2 on rod 17.
0, and the other end of the L-shaped link 20 is attached to the rod 2.
and is attached via the swinging body 26. The transmission case 11 is provided with a crank 23, and an arm 25 connects the crank 23 and the front and rear intermediate position of the upper link rod 24 of the vertical movement device 22. Further, the crank 23 and the swinging body 26 are connected via a rod. 27 is a lower link rod. A beak-type planting device 28 is provided at the rear end of the upper link rod 24 and the lower link rod 27. 29 is a cylindrical portion, and 30 and 31 are beak blades. The cylindrical portion 29 is vertical when the beak-type planting device 28 reaches the top dead center, and the bisector α-α with the square hole 8 in the bottom row of the seedling box 7 has a rotation angle of 45 degrees. A shaft 32 is provided. Attached to the rotating shaft 32 is a pyramid 33, which is a rotary delivery member and has a large diameter on the lower side and a small diameter on the upper side. The generating line β-β of the pyramid 33 is horizontal at the top and vertical at the bottom. On the outer circumferential surface of the pyramid 33 are clamping pieces 3 that support the seedlings 10 with soil pushed out from the square holes 8 of the seedling box 7 by the extrusion rods 14 from both sides.
5,35 are provided. The bottom of the pyramid 33 is provided with a guide groove 36 that has a larger diameter than the bottom and projects outward. The guide wall 36 is cut out at two opposing places to form entrances and exits 37 and 38.

As shown in FIG. 1, when the output shaft 19 rotates, the extrusion rod 14 rotates via the arm 18, rod 17, and arm 16 to push out the seedling 10 with soil, and the extruded seedling 10 with soil is held between the right and left gripping pieces. It is sandwiched by 35, 35. However, when the rotating shaft 32 rotates,
When rotated 180 degrees, it aligns with the entrance/exit 38 and the seedling 10 with soil falls into the cylindrical part 29 under its own weight. When the crank 23 rotates, the vertical moving device 22 moves up and down via the rod 25 for planting.

With conventional beak-type transplanters, when the upper end of the cylindrical part of the beak-type transplanter comes into contact with the lower part of the seedling box when attempting to transplant, the seedlings with soil do not move as planned;
Sometimes I would fail. That is, in the conventional device, when the beak-type transplanting device is moved upward in a crank motion and just when it comes into contact with the bottom surface of the seedling box, the seedlings are pushed down from above with a drop-off rod at the right time. However, with conventional systems, the beak-type planting device descends as soon as it reaches top dead center, so it is difficult to get the timing right when the beak-type planting device reaches top dead center, which sometimes results in failure. It was.

In the present invention, a seedling box 7 in which a large number of square holes 8 are arranged in parallel vertically and horizontally is mounted on a traveling vehicle body 1 that runs under the power of an engine 2, and a beak-type planting device 28 is installed near the seedling box 7.
is provided between the seedling box 7 and the beak-type planting device 28,
The soiled seedlings 10 for field work are equipped with a rotary delivery member that fits the soiled seedlings 10 pushed out from the back side of the seedling box 7 one by one, rotates them, and drops them onto a beak-type planting device 28. The transplanting device and seedling box 7 are arranged in a vertical manner between the lower end of the device and seedling box 7 and the beak-type planting device 28 located at the top dead center. A rotating shaft 32 is provided, and the rotating shaft 32 has a pyramid 3 whose generatrix β-β is between horizontal and vertical.
3 has the above-mentioned configuration in which a guide wall 36 is provided at the bottom of the pyramid 33 at a right angle to the generatrix β-β of the pyramid 33, so that the efficiency is increased and the timing can be ensured.
