Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a paddy working machine for spraying seeds and fertilizers into a paddy field, and particularly to a structure of a grooving member for digging a groove for burying seeds or fertilizers in the paddy field Regarding

[Conventional technology]

A rice transplanter, which is one of the paddy field working machines, is equipped with a fertilizer application device that spreads fertilizers in the vicinity of the planted seedlings during seedling planting work, and is disclosed, for example, in Japanese Utility Model Publication No. 62-42710. As described above, as a grooving member, a thin plate-shaped grooving plate and a grooving device are provided, and by both of these, fertilizer is intermittently fed into a groove dug near the planted seedling.

[Problems to be Solved by the Invention]

Since foreign matters such as straw debris and weeds are scattered in the paddy field where fertilization or sowing work is performed, the foreign matters are easily entangled with the grooving plate and the grooving device. Therefore, as disclosed, the lower side of the grooved plate in the rice field can be made as gentle as possible, or a rotating disk or the like can be placed in front of the grooved plate to push in the impurities downward. However, when the foreign matter comes into contact with the lower side of the groove plate, it is pushed downward as it slides along the lower side. If the surface is damaged and becomes rough, long and soft straw scraps or the like will be caught in the rough surface of the lower side and entangled with each other.

Here, the present invention aims at obtaining a structure in which foreign matters are less likely to be entangled with the grooved plate, focusing on the above problems.

[Means for Solving the Problems]

The feature of the present invention is that, in the groove construction structure of the paddy work machine as described above, the vibrating piece that is vibrated and driven by the vibrating mechanism is arranged along the lower side of the groove plate, and the vibrating piece and the lower side of the groove plate are arranged. Is filled with an elastic resin, and its action and effect are as follows.

[Work]

As described above, in the groove cutting plate that is rushed and arranged in the rice field, the lower side (vibrating piece) where the scraps are most likely to be entangled is driven to vibrate. Even if it is entangled, the shavings leave the bottom side and flow backward due to the vibration.

Further, since the space between the vibrating piece to be vibrated and the groove body of the fixed side is filled with the elastic resin, it is possible to prevent dust and dirt from entering between the vibrating piece and the body of the groove board. ,
The drive of the vibrating piece is not hindered.

〔The invention's effect〕

As described above, by vibrating the lower side of the grooving plate for grooving, which is most prone to entanglement of straw chips, the entanglement of straw chips to the grooving plate can be reduced, and stable grooving is achieved. It became possible to perform the fertilizing plate seed work by.

Further, in contrast to the structure that vibrates the entire grooved plate, by vibrating the lower side portion where the most easily entangled with straw chips, it is possible to reduce the resonance phenomenon of parts other than the grooved plate such as the hose and float, It is not accompanied by the adverse effect of vibrating the lower side portion (such as straw dust and mud entering between the vibrating piece and the grooving plate).

〔Example〕

Hereinafter, the present invention will be described with reference to the drawings using a riding-type rice transplanter, which is one of paddy field working machines.

As shown in FIG. 2, the planting arm (2) is vertically driven by the link mechanism (3) at the rear part of the planting mission (1), and the seedling is reciprocally laterally driven at the upper part of the planting mission (1). Nose stand
(4), a planting mission (1) is equipped with a float (5) for leveling and maintaining posture at the bottom of the mission (1) to form a seedling planting device, and this seedling planting device uses a four-link mechanism (8). It is connected to the traveling machine body (not shown) via the up and down operation freely.

Then, the fertilizer applicator composed of the tank (7) and the feeding part (9) is supported by the frame (6) on the upper part of the planting mission (1), and the feeding roll (9a in the feeding part (9) is ) Drive arm (10) and link mechanism (3) are interlockingly connected via a rod (11), and the feeding roll (9a) reciprocates in conjunction with the vertical movement of the planting arm (2). Driven, tank
(7) The granular fertilizer stored in the inside is fed out quantitatively. The fed fertilizer passes through the hose (12) and the grooving plate.
It is sent to the ditch that is dug on the rice field with (14) and the grooving device (13).

Next, the groove cutting plate (14) and the groove making device (13) will be described in detail. As shown in FIG. 1, the groove cutting plate (14) is made of resin and has a certain thickness (about 20 to 30 mm). And has an inverted triangular shape in a side view, and is bolted to the lower surface of the float (5). On the other hand, the grooving device (13) is formed by bending a plate material into a U shape in plan view, has a width substantially the same as that of the grooving plate (14), and is arranged at the rear part of the grooving plate (14). There is. And
A vibrating piece (15) made of metal is arranged along the lower side of the groove plate (14), and a rubber as an elastic resin (16) is provided between the vibrating piece (15) and the lower side of the groove plate 14. Not filled. Further, an electric vibration mechanism (17) is connected to the rear end of the vibrating piece (15) to drive the vibrating piece (15) in an oscillating manner.

[Another embodiment]

As shown in FIG. 3, the vibrating element (15) is swingably mounted around the horizontal axis (P ₁ ) at the front of the groove plate (14) and the vibrating element (1
5) may be extended rearward and placed through the grooving device (13). As a result, it is possible to prevent entanglement of straw scraps on the grooving plate (14) and prevent fertilizer and the like from adhering and accumulating in the grooving device (13).

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
