Abstract

PROBLEM TO BE SOLVED: To deform a nonwoven fabric into a corrugated shape as a wheel is rotated on the ground surface, so as to prevent soil from being stuck on the front surface, by sticking the nonwoven fabric on the front surface of the outer peripheral curved surface of the wheel to be mounted on a working machine such as a soil disinfector. SOLUTION: In a manual seeding machine in which a wheel 2 with lugs in which lugs 2a... are radially provided on the wheel side surface edge, is supported on the front part of an electric chain case 4, and a guide wheel 3 is supported to the rear end of a frame 8, a nonwoven fabric 1 such as a felt is stuck on the front surface of the outer peripheral curved surfaces of the wheel 2 with lugs and the guide wheel 3 over the whole surface. Since this nonwoven fabric 1 is formed of a soft material, the ground contact surface is moved and corrugated by the rotation of the wheel on the ground surface, and the shape is deformed. Sediment stuck on the front surface is easily dropped by the deformation. Also when the wheel is strongly pressed to the ground surface, sediment is not easily stuck by the deformation since the nonwoven fabric 1 is made flex and deformed against pressing force.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing sediment adhesion of wheels supported on a working machine such as a soil disinfecting machine or a seeding machine which is pulled or manually pushed by a management machine. .

[0002]

2. Description of the Related Art Conventionally, a management machine traction type or a manual push type has been used.
BACKGROUND ART Working machines such as a soil disinfecting machine and a seeding machine are supported by hard wheels made of a metal such as a laterally oriented cylinder. The outer peripheral curved surface of the wheel is hard and smooth.

[0003]

In the process of rotating such a wheel while pressing it against the ground surface, earth and sand tend to adhere to the surface of the wheel outer peripheral curved surface due to the pressing force of the wheel against the ground surface. Such adhesion of the earth and sand leads to the lifting of the wheel from the ground surface, and the soil disinfection and sowing work become unstable. There is also known a structure in which a scraper is attached to the outer periphery of a wheel to remove the attached earth and sand. In this case, too, the earth and sand easily accumulate in the scraper portion, and an operation of appropriately removing the earth and sand is required. If the surface of the curved outer surface of the wheel itself has a structure to which the earth and sand are not easily adhered, such an operation of removing the earth and sand is not required.

[0004] In order to solve the problems described above, the present invention
The following means are used. That is, a nonwoven fabric is stuck on the surface of the outer peripheral curved surface of the wheel.

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a manual seeder that employs a structure for preventing soil adhesion on wheels according to the present invention, FIG. 2 is a perspective view of a soil disinfecting machine driven by a management machine, and FIG. FIG. 4 is a schematic side view showing a state of deformation of the nonwoven fabric 1 accompanying rotation of the grounding wheel A, and FIG. 4 is a side view schematically showing a state of deformation of the nonwoven fabric W due to strong pressing of the grounding wheel W against the ground surface.

First, the structure of the manual seeder shown in FIG. 1 will be described. At the front of the transmission chain case 4, a lug 2 is attached to the side edge of the wheel to improve the grounding property so that the wheel does not float.
a, 1a... are radially attached, and a lug-equipped wheel 2 is journalled. A seeding feeding device 5 is journaled at the rear of the transmission chain case 4. A hopper 6 is mounted on the sowing feeding device 5. The hopper 6 is filled with seeds, the lug-equipped wheel 2 rotates, and the seeding feeding device 5 is rotationally driven through a transmission chain provided in the transmission chain case. The seed or seeds are fed out, and seeds are released to the ground surface from a seeding guide 7 extending below the seeds and seeded. In addition,
The hopper 6 may be filled with granular fertilizer and used for dispersing the fertilizer.

A frame 8 extends rearward in front of the transmission chain case 4, and a handle 9 is provided above and behind the frame 8.
Is extended. The operator pushes the manual seeder with this handle. At the rear end of the frame 8, a pair of left and right guide wheel arms 10 is rotatably extended rearward, and the guide wheel 3 is pivotally supported between the left and right guide wheel arms 10. Further, a scraper 11 is extended behind the guide wheel 3 shaft support portion of the guide wheel arms 10 and 10 to scrape off dirt and sand adhering to the surface of the outer peripheral curved surface of the guide wheel 3. It is attached to the curved surface.

In the manual seeder having such a structure, a nonwoven fabric 1 such as felt is attached to the entire surface of the outer peripheral curved surface of the wheel 2 with lugs and the guide wheel 3. This material may be a planted cloth material.

The non-woven fabric 1 attached to the lug-equipped wheel 2 and the guide wheel 3 (together with the lug-equipped wheel 14 and collectively referred to as a wheel W) is a flexible material, and as shown in FIG. As the ground surface moves due to the rotation on the ground surface G, the shape is deformed such as waving. This deformation makes it easier for the earth and sand attached to the surface to fall off. Further, as shown in FIG. 4, even when the wheel W is strongly pressed against the ground surface G, the nonwoven fabric 2 bends and deforms in response to this pressing force, so that the earth and sand hardly adhere.

[0010] Even if a sponge is stuck in addition to the nonwoven fabric 1,
A similar effect can be obtained, but in the case of a sponge, the durability is poor and the frequency of replacement work is high. For nonwoven fabric 1,
It is durable and the replacement work is reduced.

As another embodiment, a management machine-traction type soil disinfection machine shown in FIG. 2 will be described. In the soil disinfection machine, wheels 14 with lugs are pivotally supported on a frame 12 on which a pump amount adjusting device 13 is attached, and lugs 14a, 14a. It protrudes. Further, the nonwoven fabric 1 is stuck on the surface of the outer peripheral curved surface of the wheel 14 with lugs. Above the lug-equipped wheels 14, a pump base 15 also serving as a scraper for scraping off earth and sand is mounted, and chemical pumps 16, 16 are mounted on the pump base 15. A chemical solution tank mounting portion is formed in front of the lug-equipped wheels 14 and 14 of the frame 12, and a chemical solution tank 17 is mounted thereon, and suction pipes 18 and 18 are connected to the chemical solution pumps 16 and 16. Discharge pipes 19 are connected to a subsoiler (not shown in FIG. 2) inserted into the soil from the chemical liquid pumps 16. Further, a hitch portion (not shown) is formed at the front end of the frame 12 and is connected to the management machine K.

When the control machine K is driven to travel, the wheels 14 with lugs rotate together therewith. During this rotation, the outer peripheral curved surface like the wheels 2 with lugs and the guide wheels 3 in the manual seeder described above. The nonwoven fabric 1 stuck on the surface is deformed, and it becomes difficult for earth and sand to adhere to the surface. The lug-equipped wheels 14 and 14 rotate, and the chemical motion pumps 16 and 16 are driven to suck and discharge by the cam motion due to the rotation, so that the chemical solution is sucked from the chemical solution tank 17 and discharged into the soil.

[0013]

As described above, the present invention has the following advantages. That is, by attaching the nonwoven fabric to the surface of the outer peripheral curved surface of the wheel as in claim 1, as the wheel rotates on the ground surface, the nonwoven fabric is deformed into a wavy shape or the like. It becomes difficult to adhere to the surface. Therefore, it is possible to provide a wheel to which soil is less likely to adhere, and to apply the wheel to a working machine such as a manual sowing machine or a management machine-traction type soil disinfecting machine, so that the work can be performed without the soil being attached to the wheel. The wheel is not lifted, the work accuracy is improved, and the work of removing earth and sand is reduced.
