Description

[Detailed description of the invention] The present invention includes pressing parts that act on both sides of the upper surface of the bed of the soiled seedling block held by the planting nails, and also allows the stems and leaves of the soiled seedling block to pass between these pressing parts. A seedling pushing metal fitting having a space and configured to push out the holding seedling block toward the distal end side of the planting claw may be provided with a member for preventing movement between the pressing parts on the floor during a pressing action. Regarding a seedling pusher for a rice transplanter.

The L-note pusher is designed to ensure that seedlings are pushed out by the action of the pressing part, and to prevent damage to the seedlings due to the space. Because it was open toward the base end, when planting in soil that provides great resistance to the pushing of the seedling block, such as hard muddy soil, the floor surface may move between the pressing parts due to the resistance. As a result, there were problems such as the bed being caught in the seedling pusher, making it difficult to separate the seedlings, and the remaining bed being accumulated, causing problems in driving the pusher.

Therefore, in order to solve these problems, for example, as described in Japanese Patent Application Laid-open No. 53-38511, a metal ring is fitted on the outer periphery of the pressing part of the extruded metal fitting, and this metal ring is attached between the floor surface and the upper surface. It has been proposed that the seedlings are planted in contact with the ground and the seedlings are prevented from pulling out upward through the space between the pressing parts due to the resistance to the ground.
This device has the following drawbacks because it is attached with the metal ring protruding outside the pressing portion.

In other words, the dimension between the outer surface of the pressing part is such that the distance between the inner edge of the seedling outlet of the seedling stand and the outer surface of the pressing part is approximately the same in order to achieve good seedling separation. It is necessary to set the dimensions so that small pebbles etc. do not get between them, and it is necessary to satisfy mutually contradictory conditions.

However, in the method proposed in the above-mentioned publication, if the distance between the pressing parts is set to a size that allows for good seedling removal, the metal ring will come into contact with or collide with the inner edge of the seedling removal opening.
On the other hand, if the metal ring is set to a size that allows it to pass through the seedling take-out port, pebbles and the like will easily get stuck between the inner edge of the seedling take-out port and the outer surface of the pressing part, impeding the swinging of the planting claw. In addition, it has the disadvantage that it damages the inner edge of the seedling removal opening, making it impossible to take out the seedlings in a good manner.

The present invention makes it possible to avoid the above-mentioned problems, prevent unnecessary damage to seedlings due to the configuration, and furthermore, eliminates the need for manual adjustment work in response to such situations. The purpose is to make it easy to
In the seedling extrusion tool for a rice transplanter mentioned above, a pair of attachment parts provided with a notch groove for loading and unloading the member from the opening side of the seedling pusher fitting to the pressing part are provided between these attachment parts along the seedling extrusion direction. The connecting part of both mounting parts is positioned on the lower end surface of the pressing part, and the width dimension between the outer surfaces of each mounting part on the pressing part side in the installed state is , characterized in that the width between the outer surfaces of the pressing portion is set to be closer to the center than the width between the outer surfaces.

That is, the problem caused by the above-mentioned movement on the floor can be avoided by the action of the blocking member, and since the blocking member can be attached and detached, if the seedling pushing resistance of the planting soil is small, the seedlings will be slightly Seedlings can now be adequately protected by eliminating the blocking member, which is disadvantageous in terms of protection.

Furthermore, if the blocking member protrudes from the outer surface of the pressing part when attached, the protruding part interferes with the seedling stand, so it is necessary to change the width of the seedling take-out opening when attaching and removing the blocking member. If the width of the seedling outlet is positioned between the outer surfaces of the pressing part in the attached state as shown in FIG. It has become possible to set dimensions that fully satisfy the mutually contradictory conditions of easy separation of seedlings and no entrapment of small pebbles, etc., and it has become possible to separate and remove seedlings in a good manner.

Embodiments of the present invention will be described below based on the drawings.

The seedling planting section of the rice transplanter is equipped with an arm 2 that is rotatably driven in one direction in a planting mission case 1, and one end of a swing lever 3 is pivotally supported.
A planting arm 6 equipped with a pair of planting claws 4, 4 and a seedling pusher 5 is pivotally connected at its rear end to the free end of the swinging lever 3, and at the same time, its intermediate portion is connected to the rotating arm 2. Seedling planting in which the planting claws 4, 4 are pivotally connected to the free end of the arm 2 so that the planting claws 4, 4 rotate along a fixed trajectory as the planting arm 6 swings due to the rotation of the arm 2. constitutes a device; furthermore, for seedling planting, there is an inclined seedling platform that moves back and forth from side to side with the rotational trajectory of the planting claws 4, 4, with the seedling take-out lower facing the rotational trajectory of the device; 8 is provided.

Then, a predetermined amount of seedling blocks 9 with soil are taken out from the seedling table 8 by the rotating planting claws 4° 4, and held, and the holding seedling blocks 9 are planted in the field. During planting, a drive mechanism (not shown) inside the planting arm 6 drives the seedling pusher 5 to protrude from the planting arm 6 and hold the seedling block on its tip side against the planting claws 4. It is configured to extrude 9.

The seedling pusher 5 is constructed as shown in FIG.

That is, the plate material is bent into a U-shape, and the planting nails 4, 4 are
Toho is a pair of pressing parts 13.1 spaced apart from each other by the same distance.
A seedling pusher 11 equipped with a seedling pusher 3 is attached to the tip of a rod 10 protruding from a planting arm 6 with its opening side positioned on the side of the planting claws 4, 4.

When pushing out the seedling block 9 held by the planting claws 4, 4, the pair of pressing lower end surfaces 13a, 13a are used to apply pressing force to both sides of the upper surface of the bed 12 of the seedling block 9. At the same time, a space A is provided between the pressing parts 13 and 13 for passing the stem and leaf part 14 of the seedling block 9 held by the planting claws 4, 4.

In addition, when planting in soil that has a large resistance to the pushing of the seedling block 9, when the pressing part 13.
A removable member 15 that prevents the seedling from moving upward through the gap between the seedlings and the planting arm 6 is attached to the seedling pusher 11.
It is designed to be installed on.

As shown in FIG. 2, the blocking member 15 is made of synthetic resin.

That is, a pair of attachment parts 16.16 each having a notch groove 16a for insertion into the pressing part 13.13 from the opening side of the seedling pushing metal fitting 11 is placed between the attachment parts 16.16 along the length of the rod 10. Connected with a space B along the direction,
This makes the whole structure U-shaped.

The connection portion 17 of both attachment portions 16 and 16 is positioned on the rod 10 side so as to be attached, and in the attached state, the foliage portion of the seedling block 9 held by the planting claws 4 is placed in the space B. It is designed to pass 14.

In addition, in order to eliminate the need to widen the width of the seedling sound extraction lower, the pressing part side of each mounting part 16. The outer surface 16b is the pressing portion outer surface 13b.

The width dimension is set so that it is located between 13b and 13b.

Furthermore, in the installed state, the pressing force of both pressing parts 13.13 is applied to the seedling block 9 via the lower end surfaces 18 of both mounting parts 16.16.
