Description

[Detailed description of the invention] The present invention relates to a seedling planting machine with a seedling feeding adjustment device.

Conventionally, for example, when planting rice using a 4-row rice transplanting device, if there were only 3 rows left after the last planting, the rice would be planted by trampling over the 1 row that had been planted. When planting, three or two rows were planted to ensure a width of four rows at the end.

In other words, a clutch called a ridge clutch is installed,
Planting operations for some of the planting rods are suspended.

In this way, if the row clutch is used to stop planting some of the planting rods, a width of 4 rows can be ensured in the end. It can be planted in rows.

That is, the planting rod is vibrated in the air so that the seedlings do not stop in the seedling tank and fall down to the planting rod.This invention relates to a stopper provided in the latter seedling tank to prevent the seedlings from falling. He invented many things.

Therefore, the present invention has been devised by installing window holes in the bottom plate of the seedling tank that moves laterally in the left and right directions in relation to the planting operation of the planting rod.
Guide rolls are provided at both the upper and lower ends of the window hole, and between the guide rolls, a seedling feeding belt with a large number of protrusions on the surface is hooked and rotated. A stopper is provided to prevent the placed seedlings from moving downward due to the rotation of the seedling feeding belt, and the stopper is rotatably provided between a stopper action position and a stopper non-action position, and the stopper A seedling transplanter with a seedling feeding wrist knob device whose lower edge is located slightly above the protrusion on the surface of the seedling feeding belt when the stopper is in the action position, and a seedling tank attached to the top surface of the seedling tank. A seedling transplanter with a seedling feed stop device, which is provided with a seedling floating prevention rod for preventing the seedlings placed thereon from floating, and the stopper is stopped at a stopper action position by the seedling floating prevention rod, and A seedling transplanter with a seedling feed adjustment device is configured such that an intermediate roll is provided at an intermediate position between the upper and lower guide rolls, and the lower edge of the stopper faces the intermediate roll.

The seedling feeding belt 17 is installed so as to project above the bottom plate 18 of the seedling tank 8, and the seedlings with soil attached inside the seedling tank 8 come into contact with the seedling feeding bell (17) and move in the direction of the planting rod. sent to. The lower shaft 16 of the shafts 15 and 16 is a drive shaft, and an actuating arm 20 is attached to the shaft 16 via a one-way clutch 19. The actuation arm 20 has a protrusion 21 formed at its tip. The shaft 15 is attached with a spring 22 and is constantly pulled to the upper position, thereby tensioning the seedling feeding bell (17). A large number of protrusions 23 are formed on the surface of the seedling feeding belt 17. The operating arm 20 is constantly pulled downward by the elasticity of the spring 24. The lower end of a rod 25 is pivoted at an intermediate position in the length direction of the actuating arm 20, and the upper end 26 of the rod 25 is supported by a support fitting 27 provided at a position above the guide roll 13 so as to be vertically slidable. There is. The upper end 26 of the rod 25 has several inserts 028 in the length direction of the rod 25.

is facing, and the seedling feeding cam 32 is constantly rotating. 3
3 is a handle formed at the upper end 26 of the rod 25. A through hole 34 is bored in the shaft 15, and the lower end 35 of the spring 22 is inserted into the through hole 34. Reference numeral 36 denotes a mounting frame, which is made entirely of angle steel. A through hole 37 is formed at the lower end of the mounting frame 36, through which the shaft 16 is inserted, and a long hole 38 with a notch 39 is formed at the upper part of the mounting frame 36. 7, the shaft 15 is fitted through the notch 39, the lower end 35 of the spring 22 is engaged with the through hole 34, and the upper end of the spring 22 is engaged with the bent portion 40 at the upper end of the mounting frame 36. let

In addition, in FIG. 5, the elasticity of the springs 22 at both left and right ends is as follows.
It is formed to have half the elasticity of the central spring 22.

A stopper 41 is provided at the lower end of the seedling tank 8. The stopper 41 has a lower portion fixed by a shaft 42 and an upper portion having a free end. The stopper 41 has a mouth-like front shape and is formed by a stopper plate 43 and left and right support arms 44. The stopper plate 43 comes into contact with the lower side of the seedling 49 to prevent the seedling 49 from moving downward, and has a cut groove 45 formed therein. J on the top of seedling 49
f A seedling lifting prevention rod 46 is provided, and when the stopper plate 43 is rotated to the operating position, the cut groove 45 fits into the seedling lifting prevention rod 46, and the lower edge 47 prevents the seedlings from floating. It stops when it faces slightly above the protrusion 23 of the feed belt 17.

The stopper plate 43 rotates about the shaft 42 from the stop action position to the stop non-action position. An intermediate roll 48 is provided between the upper and lower guide rolls 13, 14, and the lower edge 47 of the stop plate 43 faces the intermediate roll 48 in the working position.

Next, we will discuss the effect.

When you sit on the driver's seat 2/hold the steering wheel 5 and operate the lever of the hydraulic system to move the vertical movement device 6 upward,
The rice-transplanting device 7 moves upwards, and is able to travel as desired and arrive at the target rice field. There, the rice-transplanting device 7 is lowered by operating the hydraulic lever from the driver's seat 2, and the rice-transplanting device 7 is moved forward in the rice field.
Seedlings 49 placed in a seedling tank 8 are divided one by one using a planting rod 9 and planted in a paddy field. When the planting with the planting rod 9 is completed in one horizontal row and the seedling tank 8 is moved horizontally to one end, the protrusion 21 of the actuating arm 20 engages with the constantly rotating seedling feed cam 32, and the actuating arm 20 The guide roll 14 is rotated by moving upward at a certain angle, and the seedling feeding bell (17), which is hooked between the guide rolls 13 and 14, is rotated to send out one seedling. In this case, the rod 25 moves upward together with the operating arm 20 and protrudes above the support metal fitting 27, but when the engagement between the protrusion 21 and the seedling feeding cam 32 is released, the rod 25 moves downward until the pin 29 collides with the support metal fitting 27. It will move.

Therefore, depending on the position where the pin 29 is inserted into the insertion port 28, the rotation angle of the actuating arm 20 changes, and the amount of feed of the arm 49 can be adjusted.

However, when the hydraulic operating lever is operated to move the vertical movement device 6 upward, the upper end 26 of the rod 25 can be reached by slightly extending a hand even while sitting on the driver's seat 2, so there is no need to descend into the rice field. Can be adjusted.

In the embodiment shown in FIG. 1, the upper end 26 is shaped like an umbrella handle 33, and in this case, it can be operated manually by checking the condition of the seedling. Namely 1. If the seedlings are not moved sufficiently depending on the situation in the seedling tank 8, when you hold the handle 33 and pull it upward, the protrusion 21 and the seedling feeding cam 32 will engage, preventing the operating arm 20 from rotating. Since the actuating arm 20 can also be directly rotated by the rod 25,
Seedlings can be sent out and arranged.

However, when the seedling feeding belt 17 is rotated by the upper and lower guide rolls 13 and 14 provided in the window hole 12, if the seedling feeding belt 17 loosens even a little, it will slip. 15 is fitted into the elongated hole 38 of the mounting frame 36 so as to be vertically movable, and is constantly pulled by the spring 22, so that it does not loosen. Further, since the lower end 35 of the spring 22 is inserted into the through hole 34 of the shaft 15, the shaft 15 is prevented from rotating together.
Prevent wear.

However, as the work progresses and nears the end, if you do not leave enough space at the end, for example when planting 4 rows, you will end up trampling over the planted ones.In this case, the stopper 41 should be By rotating the seedling 42 around the center, as shown in FIG. 3, the seedling 49 is prevented from descending and planting is prevented, and the same function as a row clutch is expected. In this case, the seedlings 49 whose descent is prevented by the stopper plate 43 bend toward the seedling feeding belt 17 and press it (Fig. 8), but the intermediate roll 48 receives the pressing force. .

Conventionally, for example, when rice is planted using a 4-row rice transplanting device, if the last planting leaves only 3 rows and 0, the rice will be planted by trampling over the 1 row that was planted.
When performing the last planting, in order to secure the width of four rows at the end, a clutch called a ridge clutch is operated, and some of the planting rows are planted without work. let it stop,
I was planting 3 rows or 2 rows. however,
For example, it is possible to plant in three rows without providing a row clutch.

In the present invention, a window hole 12 is provided in the bottom plate 18 of the seedling tank 8 that moves laterally in the left and right direction in connection with the planting operation of the planting rod 9, and guide rolls 13 and 14 are provided at both upper and lower ends of the window hole 12. A seedling feeding belt 1.7 having a large number of protrusions 23 on its surface is hung between the guide rolls 13.14,
The seedling tank 8 is provided with a stopper 4'l that prevents the seedlings 49 placed in the seedling tank 8 from moving downward due to rotation of the seedling feeding belt 17, and the stopper 41 is located between the stopper action position and the stopper plate. The stopper 41 is rotatably provided between the stopper 41 and the non-operating position, and the lower edge 47 of the stopper 41 is slightly above the protrusion 23 on the surface of the seedling feeding belt 17 when the stopper 41 is in the stopper operative position. - a seedling planting machine with a seedling feeding stop device, and a seedling floating prevention rod 46 provided on the upper surface of the seedling tank 8 to prevent the seedlings 49 placed on the seedling tank 8 from floating; The stopper 41 is a seedling planting machine with a seedling feeding stop device that is stopped at a stopper action position by the seedling lifting prevention rod 46, and an intermediate roll 48 is provided at an intermediate position between the upper and lower guide rolls 13 and 14. , the stopper 41
Since the lower edge 47 is configured as a seedling transplanter with a seedling feed adjustment device facing the intermediate roll 48, as the work progresses and nears the end, for example, when planting 4 rows, leave a gap that much. If you don't, you'll end up trampling over what you've planted.
In this case, by rotating the stopper 41 about the shaft 42, as shown in FIG. 3, the seedlings 49 are prevented from descending and planted, and the same function as a row clutch is expected. In this case, the seedlings 49 whose descent is prevented by the stopper plate 43 are transferred to the seedling feeding belt 1.
It will bend towards 7 and press this (Figure 8)
, the intermediate roll 48 has the effect of absorbing the pressing force.
