Description

[Detailed explanation of the invention] In general, when planting seedlings with a rice transplanter, in sandy fields where it is difficult for the seedling blocks to penetrate into the soil, the seedlings may be planted shallowly or the planting posture may be disturbed, making it difficult to properly plant the seedlings. There was a problem that made it difficult to carry out seedling planting work.

For this reason, a trencher is provided at the front of the seedling planting device in the forward direction of the machine body to penetrate into the planting soil and form a trench in advance at a location corresponding to planting, and the seedlings are placed in the trench dug by the trencher. has been shown to be planted.

For example, Utility Model Publication No. 50-923, and Utility Model Publication No. 4
Publication No. 9-11551.

However, in the former method, which reduces the insertion resistance when planting seedling blocks by digging a groove approximately the same width as the width of the seedling block, the seedlings are planted directly into the ground without forming a groove. There is no resistance to push out the seedlings, and there is a disadvantage that the seedlings dance when pushed out and planted, and the planted seedlings fall back and forth.
In addition, in the case of the latter, in which grooves are formed in advance using a thin pushing board for pushing straw and other miscellaneous materials into the soil, the grooves are filled in at the same time as the straw and miscellaneous materials are embedded, so the seedling block is It has the disadvantage that it is difficult to penetrate into the soil, resulting in shallow planting and unstable planting posture.

The purpose of the present invention is to dig a groove with approximately the same width as the width of the seedling block and plant the seedlings in the groove, and to enable the seedlings to be planted well.

The technical means of the present invention taken to solve the above problem is that the seedling blocks that are planted by the planting claws are placed in the forward position of the seedling planting device in the direction of movement of the machine body, and in the forward position of the planting location by the planting claws. A trench digging tool that forms a groove to reduce resistance to insertion into mud is provided, and at the rear of the trench digging tool and in front of the planting claw, soil on both sides of the trench is provided. A flat plate-like soil tool with an appropriate length in the front-back direction and a width extending across both sides of the groove was provided to contact and cover the opening in the upper part of the groove with the coating.

The effects of taking the above technical measures are as follows.

In other words, instead of forming a narrow groove with a thin pushing plate for pushing straw and miscellaneous materials into the soil, a relatively wide groove is used to reduce the resistance to inserting the seedling block into the mud. The upper part of the dug trench is closed with a soil tool to make it hollow inside, so when planting the seedling block, it can be prevented from penetrating into the soil, just like when the entire trench is buried. It does not receive a large push-in resistance that would be a hindrance, can provide appropriate resistance to the seedlings when pushing out the seedlings, prevents the seedlings from dancing, and allows the seedlings to be planted well. Since the roots of the planted seedling blocks are held in the soil that closes the upper part of the groove, it is possible to prevent the seedling blocks from being disturbed in their posture after being planted.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

The figure shows a seedling planting device 1 equipped on a walk-behind rice transplanter, which includes an inclined seedling platform 2 that moves back and forth horizontally at a constant stroke, and a vertically circulating system between the lower end of this seedling platform 2 and the planting soil. It is composed of an operating planting claw 3 and a seedling pusher 4 that is driven forward and backward along the claw direction of the planting claw 3, and is placed on the seedling platform 2. Along the lower end row of the seedling group W, the seedling blocks W' are successively scraped and separated one by one.
The seedling block W' is brought downward while being supported by the tip of the claw and the seedling pusher 4, and then the seedling block W' is moved into the planting soil using the seedling pusher 4 that protrudes toward the tip of the claw. The structure is such that the seeds can be successively planted while repeating the extrusion and separation operation.

In addition, 5 in the figure is a float connected and supported by the machine frame, and has the function of sliding on the mud surface to support the machine body and the function of leveling the planting soil surface in advance.

Furthermore, this rice transplanter is capable of planting seedling blocks W' accurately at a desired planting depth and posture even under conditions such as sandy soil where it is difficult for the seedling blocks W' to penetrate into the planting soil. In order to be able to do this, a trench digging tool 6 made of a bar material and a soil cutting tool 7 made of a plate material, which will be described below, are provided.

The groove digging tool 6 forms a groove having a width close to that of the seedling block W' in order to reduce insertion resistance of the seedling block W' planted by the planting nails 3 into the mud. It is connected and supported by the float 5, and is inserted into the planting soil at a location forward of the seedling planting device 2 in the direction of movement of the aircraft, and is pre-filled with a groove A at a location corresponding to planting.
It is configured to form a

The soil support tool 7 has a width spanning both sides of the groove, and
It is made of a flat plate having an appropriate front-to-back length, and is fixed to the trench digging tool 6, and is configured to exert the effect of covering the trench opening with soil near the trench opening before planting. .

When the trench digging tool 6 and the soil cutting tool 7 are installed as described above, the trench A is formed in advance by the trench digging tool 6, and the opening of the trench A is formed by the soil cutting tool 7 as shown in FIG. As a result, the seedling block W' has a groove A whose opening is closed.
Since it is planted in the groove A, it can be planted at a desired depth and in a desired posture, and at the same time as the seedling block W is planted.
Since the roots of the seedling blocks W' are held in the soil, the posture of the seedling blocks W' will not be disturbed after being planted.

In addition, in implementing this proposal, the earthenware 107 as shown in Fig. 4 will be used.
It may be pivoted to the trench digging tool 6 so as to be able to swing up and down, and elastically biased downward, so as to be pressed while following the unevenness of the planting soil surface.

In addition, as shown in FIG. 5, if the lower surface of the earth mooring tool 207 is formed into a downwardly concave surface when viewed in the front-rear direction, although both side portions of the groove A are strongly pressed, the portion directly above the groove A is Since it is not pressed too hard, it is possible to prevent the groove A from collapsing.

In addition, in the embodiment, the earth mooring tool 7 is connected and supported by the trench digging tool 6, but it may be separately attached to the machine body.
