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, and Yuheko, etc., there are known transplanting devices for top-mounted block seedlings and those for pulling out seedlings. This study was conducted using one-block seedlings (hereinafter referred to as seedlings with soil).

With conventional beak-type transplanters, when the upper end of the barrel of the beak-type transplanter comes into contact with the lower part of the seedling box when trying to transplant, the seedlings with soil may not move as planned and sometimes fail. Ta. That is.

In the conventional device, the beak-type transplanting device is moved upward with a crank motion, and when it comes into contact with the bottom surface of the seedling box, the timing is determined and the drop-off rod is used to push down the soiled seedlings from above. 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 based on top dead center, which sometimes results in failure. .

In addition, the conventional beak-type planting device rose until it directly contacted the bottom surface of the N9 box and descended until it penetrated the field, so the range of movement was long, making it impossible to plant quickly.

The present invention solves this problem by installing a seedling box with a large number of square holes arranged in parallel vertically or horizontally on a vehicle that runs on engine power. A beak-type planting device is provided near the seedling box and below the seedling box, and between the seedling box and the beak-type planting device, soiled seedlings pushed out from the back side of the seedling box are placed. A device for transplanting soiled seedlings for field work, which is equipped with a rotary transfer member that fits one by one, rotates, and drops them above the beak-type planting device at a lower position, and the lower end of the seedling box and the top dead center. A rotating shaft is installed between the beak-type planting device located in In the configuration of the device described above, in which a guide wall that is perpendicular to the generatrices of the pyramid is provided at the bottom of the substantially pyramid with i-orthogonal, there is no need to take timing, and it is simple. It was designed to be planted.

To explain with a diagram, 1 is a running vehicle body, and 2 is an engine attached to the front side of the running vehicle body 1.

3 is a front wheel, 4 is a rear wheel, and 5 is a walking steering handle.

A planting section 6 is provided at the rear of the traveling vehicle body l. Planting section 6
The seedling box 7 is placed horizontally. As shown in Fig. 2, the seedling box 7 has many square holes 8 arranged vertically and horizontally and is made of synthetic resin. Seedlings 10 are 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. The seedling box 7 is intermittently slid left and right through each square hole by eight minutes by a support arm 13 attached to a lead cam shaft 12 provided in a transmission case 11. Square hole 8 in the bottom row of seedling box 7
An extruded rod 14 is pivoted 15 on the lower side of the holder. Reference numeral 16 indicates an arm 17 which projects upward from the shaft attachment 15, and reference numeral 18 indicates an arm, which is attached to the output shaft 19 of the transmission case 11.

In FIG. 2, an L-shaped link 20 is attached to the row 17, and the other end of the bent link 20 is attached via the rod 2 and the swinging body 26. A crank 23 is provided in the mission case ti, and an arm 25 connects the crank 23 and the front-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 ends of the upper link rod 24 and the lower link rod 27. 29 is a cylinder portion, and 30.31 is a beak blade. 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 box 7 is 1°I′1.
is provided with a rotation axis 32 of 45 degrees. Attached to the rotating shaft 32 is a pyramid 33, which is a rotary receiving member and has a large diameter on the lower side and a small diameter on the upper side. The generatrix 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, clamping pieces 35, 35 are provided to support the soil 1 seedling lO pushed out from the square hole 8 of the seedling box 7 by the extrusion rod 14 from both sides.

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 an entrance/exit 3738.

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

With conventional beak-type transplanters, when one end of the cylindrical part of the beak-type transplanter touches the bottom of a seedling box when trying to transplant, the seedlings with soil do not move as planned and sometimes fail. was there. That is.

In the conventional device, when the beak-type transplanting device is moved upward with a crank motion and comes into contact with the bottom surface of the 11゛1 box, the seedlings are pushed down with a push-down rod at the right time. However, with conventional systems, the beak-type planting device descends immediately when it reaches top dead center, so it is difficult to get the timing right when the beak-type planting device reaches top dead center, and it sometimes fails. The present invention provides a traveling vehicle body l that runs with the power of an engine 2,
A seedling box 7 in which a large number of square holes 8 are arranged in parallel vertically and horizontally is installed, a beak-type planting device 28 is installed near the seedling box 7, and a beak-type planting device 28 is installed between the seedling box 7 and the beak-type planting device 28. , for field work, which is equipped with a rotary delivery member that fits and rotates the soiled seedlings 10 pushed out from the back side of the seedling box 7 one by one, and drops them onto the beak-type planting device 28. The transplanting device for seedlings 1O and the seedling box 7 are arranged vertically, and there is a line between the lower end of the device and the seedling box 7 and the beak-type planting device 28 located at the top dead center. Sloping 1! A d rotating shaft 32 is provided, and the rotating shaft 32 has a generatrix β-β.
Since the above-mentioned device has a structure in which a guide wall 36 is provided at the bottom of the pyramid 33, which is between horizontal and vertical, and which is perpendicular to the generatrix β-β of the pyramid 33, efficiency is increased, and It has the feature of ensuring timing.
