Immediately after that, the spraying section is arranged so that the drug can be sprayed from the spraying section to the surroundings, and a plurality of laterally projecting abutments are projected at the front left and right side positions of the machine body frame. The abutment makes it possible to guide the machine body in a desired direction by detecting a pile standing in the field.

As described above, in the above-described automatic travel control type chemical spraying machine, the operator can sit on the driver's seat to perform steering operation, and the operator can sit unattended on the driver's seat to unmanned. It is also possible to guide and steer in this state.

[0005]

However, in the above-described automatic travel control type chemical spraying machine, the branches just above and outside the driver's seat are open, so that the branches of the tree are sprayed during the chemical spraying work. There is a risk that the driver may accidentally operate the switch or the like on the driver's seat.

During the chemical spraying operation, the chemical sprayed from the spraying section adheres to the operating lever of the driver's seat, the driver's seat, etc., and these become wet or dirty, so that the operator can drive the vehicle. However, there is the annoyance of having to wipe off the attached chemicals one by one.

Further, there is a problem that the branch of the tree is apt to be damaged by the overhanging tree branch or the like when hitting the operation lever or the like provided in the driver's seat during the chemical spraying work.

[0008]

Therefore, in the present invention, a cover body for covering the driver seat portion is attached to the driver seat portion of the machine body, and the cover body is used as a use position for covering the driver seat portion. The present invention is to provide an automatic travel control type chemical sprayer characterized in that the position can be changed to a storage position where the driver's seat is opened.

It is also characterized in that it is urged in the direction, and that an appropriate number of supporting aggregates are attached to the cover body in parallel with the axis of the winding roll at predetermined intervals.

[0010]

When performing the chemical spraying work while the automatic travel control type chemical sprayer is traveling unmanned, the driver is closed by placing the cover body in the use position for covering the driver's seat. It is possible to prevent the branches of the tree from hitting the switches and the like in the driver's seat, and also to prevent the chemical sprayed from the sprayer from adhering to the operation lever, the driver's seat and the like.

Further, since the overhanging tree branch or the like does not directly hit the lever or the like of the driver's seat portion, damage to the branch or the like can be prevented.

Then, the take-up roll is attached with its axis lined in the front-back direction of the machine body, a sheet-shaped cover body is wound around the take-up roll, and the take-up roll is biased in the cover body winding rotation direction. In this case, by pulling out the free end side of the cover body against the rotational bias of the winding roll and locking it, the position can be easily changed to the use position for covering the driver's seat portion, and the cover is also provided. When the free end side of the body is unlocked, the cover body is automatically wound by the urging force of the winding roll in the winding rotation direction and can be repositioned to the storage position.

When a proper number of supporting aggregates are attached to the cover body in parallel with the axis of the winding roll at a predetermined interval, the midway portion of the sheet-like cover body hangs down by the supporting aggregates. This makes it possible to smoothly perform the work of pulling out the cover body and the work of winding the cover body, and at the same time, it is possible to ensure a good cover function.
