Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to the configuration of a grounding shoe that forms a groove at the position where seeds fall in the grounding part of a multi-sowing device.

(B) Prior art In a conventional multi-seeding device, the seeds fed out by the seeding device pass through a guide hose, drop into a recess formed on the multi-film from a guide pipe provided on the film pressing body, and are sent out. The seeds were sown on the ridge from the seed drop position of the ground shoe through the sowing hole of the multi-film.
The grounding shoe was constructed of an iron plate or the like, and a groove cutter was provided on the back of the front of the drop hole, and a cover plate was provided at the rear of the drop hole.

(c) Problems that the invention aims to solve When sowing with the above configuration, soil tends to adhere to the back of the ground shoe and the furrower, and when soil adheres to the furrower, the furrow becomes larger. If only the soil is covered with a soil cover plate, the seeds will not be covered with soil, and if soil adheres to the back of the ground shoe, the ridge surface will become uneven and it will be difficult to make grooves properly, and the ground resistance will increase, putting a burden on the management machine. They used to make it bigger.

Furthermore, even if the synthetic resin film 51 to which soil etc. does not easily adhere is pasted on the bottom surface of the V-shaped groove 50a provided at the center of the grounding shoe 50 as shown in FIG. As it moves forward on the ground, it peels off from the front and dirt and the like adhere to it, which not only deteriorates the finish, but also increases unnecessary work such as replacing the synthetic resin film 51.

(d) Means for solving the problem In view of the above points, the present invention is constructed as follows.

Multi-film 9 with seeding holes 9a drilled on the top surface
The multi-sowing method is structured so that the sowing hole 9a slides through, the sowing hole 9a reaches the seed drop position, and the seed passes through the sowing hole 9a and falls into the groove formed by the groove-making claw 47 fixed on the back side. Equipment grounding shoe 42
A resin film 46 is attached to the back surface of the grounding shoe 42, and the resin film 46 is held from below the grounding shoe 42 by groove-forming claws 47, which are also made of resin.

As shown in FIGS. 7 to 9, an inverted U-shaped mounting frame 54 protrudes below the seeding beam 53.
A ground shoe 55 and a film pressing body A' are fixedly installed at the lower end, and the structure of the ground shoe 55 is such that the front end is "open".
A resin film 56 is pasted on the bottom surface of the grounding show plate 55a bent in the shape of a square, and the bolt 5 is inserted between the resin film 56 with a wedge-shaped groove cutter 57.
It is fixed at 8,58.

The groove 57 is made of synthetic resin or the like to which soil and the like do not easily adhere, and has a support rod 57a protruding from its front end. Then, the seeds are dropped into the rear concave portion of the furrower 57 between the soil cover plates 55b, 55b protruding from the rear end of the grounding shoe 55.

In addition, as shown in FIG. 10, the groove cutter has a guide plate 60 made of a steel plate, such as stainless steel, bent into a U-shape, fixed with bolts to the rear surface of the wedge-shaped hollow groove cutter 59 made of synthetic resin. , the resin film 56 may be held between the groove creator 59 and the ground shoe 55.

(F) Function of the device With this configuration, grooves are created by the groove making claw 47 on the ridges formed by the side molded plate 21 and the upper molded plate 22, and at this time, the groove is made on the back surface of the grounding shoe 42. The sandwiched film and groove-making claws 47 made of synthetic resin are made of a material that is slippery and difficult for soil to adhere to, so they form clean grooves into which the seeds collected in the recesses of the multi-film 9 are collected. Seeding hole 9
a, the seeds fall through the drop hole 42a, and as the ground shoe 42 moves forward, the seeds are covered with soil by the soil cover plate 42d.

(g) Effects of the invention With the above configuration, the invention provides the following effects.

First, since the resin film is pasted on the back surface of the ground shoe 42, it is possible to prevent soil from adhering to the back surface of the ground shoe 42.

Secondly, since the groove-cutting claws are also made of synthetic resin, there is less adhesion of soil, etc., and the grounding resistance is also reduced.A clean groove is formed, and the seeds fall into the groove reliably. soil is then covered.

Thirdly, since the resin film 46, which may peel off if it is simply attached to the lower surface of the grounding shoe 42, is clamped and held by the groove claws 47, the resin film 46 becomes difficult to peel off. This reduces the frequency of replacement and improves durability.
