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. The present invention relates to a seedling extrusion tool for a rice transplanter, which has a space and is configured to extrude a holding seedling block to the tip side of the planting claw.

The above-mentioned seedling pusher is designed to ensure that the seedlings are pushed out by the action of the pressing part, and also to prevent damage to the seedlings due to the space. Because it was open toward the sides, sometimes during planting, especially when the field mud is hard, the soil on the bed tends to move upwards through the space between the pressing parts due to the seedling pushing resistance caused by the mud, and as a result, There have been problems such as the top of the bed gets caught in the seedling pusher, making it difficult to separate the seedlings, and the remaining top of the bed accumulates, causing trouble in driving the seedling pusher.

The purpose of this invention is to solve the above-mentioned problems while protecting the surface and suppressing the deterioration of the seedling extrusion function as much as possible through simple improvements. In the extrusion tool, a closing action part that closes the base end side of the planting nail in the space between the pressing parts, and a closing member attachment that extends from both ends of the closing action part in the planting nail juxtaposition direction to the pressing part action surface. The pressing part is provided with a U-shaped fixing member having a downwardly open cross section.

That is, the action of the fixing member can suppress the problems associated with the upward movement of the seedling pusher on the floor as described above, and furthermore, the action of the fixing member to close the base end side of the planting claw in the space between the pressing parts Since the closing part is closed at the part, that is, since the closing part is provided at a distance from the lower end surface of the pressing part to the base end of the planting nail, this closing part comes into contact with the seedling stem part. Although the upward movement on the floor can be successfully prevented, the stem can be pushed down to the side by being pressed by the upper surface of the floor and the occluding part, and the stem can be placed in an inclined position without the disadvantage of being pushed down to the side or being cut off. The upright position is maintained, and there is no disadvantage that the leaves and stems will rot due to submergence after planting, and therefore, the good function of separating the seedlings from the nails without damaging them can be exerted as much as possible. I can now do it.

Moreover, it is advantageous in practical application because it requires only a simple modification of providing a fixing member.

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

A rice transplanter is equipped with a seedling planting unit, which consists of a planting mission case 1, which is provided with an arm 2 that is rotatably driven in one direction, and which pivots on one end side of a swing lever 3. A planting arm 6 equipped with 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 its intermediate portion is connected to the free end of the rotating arm 2. For seedling planting, the device is pivotally connected to 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. Furthermore, for seedling planting, an inclined seedling platform 8 is provided which moves back and forth from side to side with the seedling take-out lower facing the rotation trajectory of the planting claws 4, 4 as the device rotates. be.

Then, a predetermined amount of soiled seedling blocks 9 are taken out from the seedling platform 8 by the rotating planting claws 4, 4, and held, and the holding seedling blocks are planted in the field. At the time of attachment, the seedling pusher 5 is driven to protrude from the planting arm 6 by an internal drive mechanism (not shown), and the seedling block is held on the tip side of the planting claws 4. It is configured to extrude 9.

The seedling pusher 5 is configured as shown in FIG.

That is, the plate material is bent into a U-shape, and the planting nails 4, 4 are
A pair of pressing parts 13.13 are spaced apart from each other by approximately the same distance.
The opening side of the seedling pushing metal fitting 11 equipped with the planting claw 4 is
, 4 side, and is attached to the tip of the rod 10 protruding from the planting arm 6.

When pushing out the seedling block 9 held by the planting claws 4, 4, a 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. That's how it is.

The member 15 for closing the space between the pressing parts 13.13 is placed in a state in which the closing action part 15a thereof is positioned above the seedling pushing metal fitting 11, that is, when the planting claws 4, 4 are placed against the pressing part 13.13. It is fixed to the seedling pusher 11 with a distance 1 spaced apart from the base end side.

The closing member 15 is fixed by pressing the action surfaces 13a, 13a of the pressing portions 13.13 from both edges in the direction in which the planting claws 4, 4 are arranged side by side.
13a, and its extended end is connected to this working surface 13a.
.

The mounting parts 15b, 15b, which are formed by covering the lower part of 13H and further bent toward the space A side between the pressing parts 13. The closing member 15 can be attached and detached by inserting and removing the portions 15b, 15b from and into the pressing portion 13.13.

That is, when the seedling pushing resistance due to the mud is large, such as when the mud in the field is hard, the closing member 15 is attached and operated as follows.

That is, the seedling block 9 held by the planting claws 4, 4,
The closing member mounting portions 15b, 15b are pushed into the field mud by the pushing force applied by the pressing portion working surfaces 13a, 13H, and the bed soil 12 is pushed between the pressing portions 13 and 13 due to the resistance of the mud. The above-mentioned blocking portion 15a and the stem portion of the seedling are prevented from moving upward through the seedling.
