Description

[Detailed Description of the Invention] The present invention relates to a walking-type mobile agricultural machine in which a working device is connected to the rear of a self-propelled machine.

Extended walk type mobile agricultural machines have conventionally been constructed to prevent crops from entering the working section during work between furrows, touching the working equipment, getting tangled with it, damaging it, or tearing it off. I found the one shown here. That is, the lateral sides and the front of the working device 4 were covered with the cover 7.

However, with conventional systems, only the working equipment is covered, which not only causes the crops to come into contact with the wheels or get wrapped around them, causing them to be damaged or torn, but also the crops to be covered by the cover. In some cases, the corner portion where the front part of the work device and the lateral side part of the work device are connected was worn and damaged. Crop damage caused by the corners of the cover can be easily avoided by making the front part of the work equipment curved to prevent sharp corners, as shown by the imaginary line, but the problem of damage caused by the wheels remains. .

An object of the present invention is to prevent damage to crops not only due to contact with working equipment, but also crop damage due to contact with wheels and covers.

This invention is based on the above-mentioned walking-type mobile agricultural machine.
A pair of left and right covers, each covering the front and lateral sides of the wheels of the self-propelled aircraft and the lateral sides of the working device, and the outer surface interval on the front end side of both covers is such that It is characterized by being provided so that it becomes smaller toward the front end, and its functions and effects are as follows.

That is, to prevent crops from touching not only the working equipment but also the wheels, the sides of the working equipment, the lateral sides of the wheels, and the front are covered with covers.
In addition, by forming each of the left and right covers so that the wheel portion and the working device portion are connected in series, and the outer surface interval on the front end side of the left and right covers becomes smaller toward the front end, crops can be easily covered. Even when in contact with the cover, it slides smoothly against the cover from the front end to the rear without getting caught, making it less likely to be scratched.

Therefore, not only damage caused by the crop working equipment but also damage caused by the wheels and the cover itself can be effectively prevented, and furrow work can now be performed in good condition without causing quality deterioration of the crops.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a rotary tiller 4 is connected to the rear of a self-propelled machine having one wheel 1, an engine 2, and a control handle 3 in a state in which power is transmitted from the self-propelled machine. Covers 5a or 5b that cover the front and lateral sides of the wheels 1 and the lateral sides of the tilling device 4 are arranged on both left and right sides of the machine body so that crops do not come into contact with the wheels 1 and the tilling device 4 during the operation. At the same time, the support member 6 of the self-propelled aircraft
and the rotary cover 7 of the tilling device 4 to form a walking type tiller.

As shown in FIG. 2, the pair of covers 5a,
5b are each formed into a curved shape in which the front end side is located inside the fuselage body than the rear end side in plan view, so that the distance between the outer surfaces on the front end side of both covers 5a, 5b becomes smaller as the front end side approaches, so that the crop is separated from the pair of covers. 5a, 5b
It is configured to move from the front end side to the rear side while smoothly sliding into contact with each other.

Both covers 5a, 5b are connected in front of the wheel 1 via the support member 6.
b The front end of each wheel is connected to the support member 6, and the wheels 1
Care is taken to prevent crops from entering the inside of the covers 5a and 5b in front of the covers 5a and 5b.

As shown in FIG. 3, the pair of covers 5a,
The upper end of each 5b is formed into a curved shape such that the upper end is positioned closer to the inside of the machine when viewed in the longitudinal direction of the machine, so that even if a crop is placed on the upper end, it will not be easily damaged by wear.

The tilling device 4 can be changed to a soil raiser or the like, and these are collectively referred to as the working device 4.
