Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a rotary cover for covering the upper part of a rotary device, the angle of which can be adjusted around an axis in the longitudinal direction of the machine body, so that the plowing soil raised by the rotary device can be covered by the rotary cover. It guides in the lateral direction of the airframe and supplies it to the root of the ridge crop, and prevents the tilled soil that has been flipped up by the rotary device between the traveling airframe and the rotary device from scattering in front of the airframe. The present invention relates to a walk-behind mobile agricultural machine provided with a plate and used for managing tillage.

[0002]

2. Description of the Related Art A conventional tillage management machine as a walk-type mobile farm machine is disclosed in Japanese Utility Model Laid-Open No. 4-48904.
A rotary cover that covers the upper part of the rotary device is configured so that the angle can be adjusted around the axial center in the longitudinal direction of the machine body, and as disclosed in JP-A-62-87001,
A scattering prevention plate is provided between the traveling machine body and the rotary device in order to prevent the tilled soil repelled by the rotary device from scattering forward of the machine body.

[0003]

When the angle of the rotary cover is adjusted to change the discharge distance of the tilled soil, a gap is formed between the rotary cover and the shatterproof plate, and the tilled soil is scattered forward of the machine body. Therefore, there is a disadvantage that the maintenance of the engine air cleaner becomes high.

An object of the present invention is to prevent the tilling soil from scattering in front of the machine regardless of the angle adjustment of the rotary cover, and to reduce the maintenance of the air cleaner and the like.

[0005]

To achieve the above object, the present invention is characterized in that a rotary cover for covering an upper portion of a rotary device is constructed so that its angle can be adjusted around an axis in the longitudinal direction of the machine body. The cultivated soil repelled by the rotary cover is guided in the lateral direction of the airframe by the rotary cover, and the cultivated soil repelled by the rotary device is prevented from scattering forward of the airframe between the traveling airframe and the rotary device. In a walk-behind mobile agricultural machine provided with an anti-scattering plate, the anti-scattering plate is provided with an elastic cover for closing a gap that abuts on an inner surface of a front portion of the rotary cover.

[0006]

[Operation] The cultivated soil repelled by the rotary device is prevented from scattering toward the front of the machine by the scattering prevention plate, and the rotary cover is angle-adjusted around the front-rear axis to release the cultivated soil distantly. However, the elastic cover for closing the gap does not form a gap between the shatterproof plate and the rotary cover, and the cultivated soil is guided to the rotary cover by the elastic cover for closing the gap.

[0007]

As a result of the above-mentioned structure, it is possible to prevent the tilling soil from being scattered to the front side of the machine body regardless of the angle adjustment of the rotary cover, and to reduce the maintenance of the air cleaner of the engine.
