Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to an improvement of a compression roller and a grounding wheel equipped in various agricultural working machines.

(B) Conventional technology Conventionally, as for the compression roller of an agricultural work machine in which a cover of a flexible elastic piece is attached to the entire peripheral surface, it is disclosed in Japanese Utility Model Laid-Open No.
The technology described in Japanese Patent No. 418 is known.

A technique such as Japanese Utility Model Publication No. 54-182309 is known as a technique for preventing soil from adhering with a cover having a two-layer structure composed of a flexible elastic piece cover and a smooth plastic thin piece.

(C) Problems to be solved by the invention For agricultural working machines such as sowing machines, fertilizer spreaders, pesticide sprayers, and soil disinfecting machines, a grounding wheel with a lug is used as a drive source for the feeding member, and the ground after work is used. The crushing roller and the grounding ring are compressed by the crusher roller, but when rolling over the soil surface, the soil tends to adhere to the peripheral surface of the crusher. Therefore, there is a problem that the functions of the compression roller and the grounding wheel are hindered.

SUMMARY OF THE INVENTION An object of the present invention is to provide a repressing roller and a grounding ring that solve such problems by a very simple means.

(D) Means for Solving the Problems The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described.

In an agricultural working machine in which a grounding wheel 5 having a lug 6 projecting from the front part is arranged and a crushing roller 8 is arranged at the rear part, a meat pressure sponge piece arranged on the inner circumference around the grounding wheel 5 and the crushing roller 8 24 and a cover 26 having a two-layer structure composed of a thin plastic thin piece 25 arranged on the outer periphery of the ground wheel 5
In the above, the lug 6 is projected from the cut formed in the cover 26 having the two-layer structure.

(E) Embodiment In the embodiment shown in FIGS. 1 and 2, reference numeral 1 is a rectangular frame, two side rods 2 spaced apart from each other, and a front shaft 3 and a rear rod for connecting both ends thereof. It consists of 4 and on the front axis 3,
A grounding ring 5 having a large number of lugs 6 ... Arranged on its peripheral surface is mounted, and a compression roller 8 is supported by an arm rod 7 attached to the rear end of the side rod 2.

This frame 1 is provided with a hand-pushing rod 10 whose length can be adjusted near the rear end of the frame 1 at an angle, and a handle 1 for changing direction at the center front part.
1 is vertically projected, and a hanging rod 12 bent in a key shape is projected at the lower center part.

Reference numeral 13 is a strip nail, which is a suspension rod 12 arranged immediately after the grounding wheel 5.
Then, the sharp edge of the front edge is cut into the ground A to cut the groove groove B having a constant width, and the soil cover plate 14 is attached to the projecting piece at the rear upper corner.

Reference numeral 15 is a box-shaped capsule having a discharge pipe 16 in the lower front corner, which is put on the outer opening of a hopper 17 mounted on the central portion of the frame 1 to drop the seed S into the capsule to remove the protrusion 18 on the front surface. It is attached to the bent piece of the suspension rod 12.

20 is a feeding roll provided with eight dents 21 on the peripheral surface,
Attached to the actuating shaft 22, approximately half of it is looked into the bottom of the capsule 15 and a brush (not shown) is placed along the front edge to keep the amount of seeds entering the recess 21 constant.

Reference numeral 23 denotes a chain case, which covers the chain wheel on the front shaft, the chain wheel attached to the operating shaft 22, and the chain (both not shown) attached to both of them, and this chain operates with the ground wheel 5 as a drive source. The shaft 22 is rotated and the feeding roll 22 is rotated counterclockwise to feed the seeds.

The above is an example of the feeding roll type seeder, and the push rod 1
When the frame 1 is advanced with 0, the grounding wheel 5 bites the lug 6 into the ground A and rotates, and the nail strip 13 moves to the ground A.
The feed groove 20 is rotated counterclockwise by using the grounding wheel 5 as a drive source, and the feeding roll puts the depression 21 into the capsule 15 and feeds it from the capsule 15. The depression passes through the brush and moves downward. When facing, the seeds fall from the discharge pipe 16 into the groove B, and the soil cover plate 14 scrapes off the soil on the side to cover the soil, and the compression roller 8 presses the soil.

In this embodiment, in such a seeding machine, as shown in FIG. 2, a sponge piece 24 and a smooth plastic thin piece 2 are used.
A cover 26 having a two-layer structure composed of 5 is placed on the entire peripheral surfaces of the pressure suppressing roller 8 and the grounding wheel 5 with the latter as an outer side, and the sponge piece 23 is integrated with the peripheral surface of the pressure suppressing roller and the grounding wheel using an adhesive. Affix to.

The ground wheel 5 has many lugs 6 on its peripheral surface,
The cover which covers this is provided with a notch at the lug 6.

In this embodiment, when the crushing roller 8 and the grounding wheel 5 roll on the cultivated land, even if soil is attached, the plastic thin piece 25 on the outer side of the cover is smooth, so that the soil slips and the soil is not attached. To be prevented.

Then, the sponge piece 24 inside the cover 26 contracts at a portion where the compression roller 8 and the grounding wheel 5 come into contact with the ground, the compression roller 8 presses the ground with its own weight, and the grounding wheel 5 puts the lug 6 on the ground. When it is made to bite and this portion is separated from the ground, the sponge piece 24 is restored by its elasticity and swells to a soft state.

The repeated contraction and expansion of the sponge piece 24 has a function of bouncing the soil that is trying to adhere to the plastic thin piece 25, and also a function of preventing the plastic thin piece from breaking.

The above is a description of one embodiment of the present invention, and the present invention is not limited to this embodiment, and the design can be changed within the scope of the invention.

For example, a foamed rubber piece may be used instead of the sponge piece, and these and their equivalent materials are collectively called a flexible elastic piece.

(F) Effect of the invention In the present invention, a cover made of a flexible elastic piece and a smooth plastic thin piece is attached to the entire peripheral surface of the compression roller and the grounding ring, which are provided in various agricultural working machines, with the latter being the outer side. Even if soil is attached, since the plastic thin piece 25 on the outer side of the cover is smooth, the soil slips, so that the soil is prevented from attaching.

Then, the sponge piece 24 inside the cover 26 contracts at a portion where the compression roller 8 and the grounding wheel 5 come into contact with the ground, the compression roller 8 presses the ground with its own weight, and the grounding wheel 5 puts the lug 6 on the ground. When it is made to bite and this portion is separated from the ground, the sponge piece 24 is restored by its elasticity and swells to a soft state.

The repeated contraction and expansion of the sponge piece 24 has a function of bouncing the soil that is trying to adhere to the plastic thin piece 25, and also a function of preventing the plastic thin piece from breaking.

In this way, the flexibility of the elastic piece and the smoothness of the plastic thin piece act synergistically to reliably prevent soil from adhering to the peripheral surface, and the function of the compression roller and the grounding ring can be achieved with extremely simple means. Has the effect of being able to hold.
