Description

The present invention relates to a working machine.

Conventionally, as a working machine, for example, the working machine described in Patent Document 1 is known. The work machine described in Patent Document 1 is provided with a work device (“threshing device [5]” in the document) and a plurality of cover members (“first side cover” in the document) that are detachably provided on the side of the work device. [21], a second side cover [22], etc. ”), and a side cover configured by being divided are provided.

Japanese Unexamined Patent Publication No. 2019-126279

In the working machine described in Patent Document 1, two cover members adjacent to each other may be relatively displaced from each other.

In view of the above situation, there is a demand for a working machine capable of preventing relative misalignment between two cover members adjacent to each other.

The features of the present invention are a working device, a side cover that is detachably provided on a side portion of the working device and is divided into a plurality of cover members, and two of the plurality of cover members that are adjacent to each other. It is provided over one cover member and includes a positioning portion for positioning one cover member of the two cover members and the other cover member of the two cover members, and the positioning portion is the one. It has a protrusion provided on the cover member of the above and projecting toward the other cover member, and an entry portion provided on the other cover member and into which the protrusion enters.

According to this feature configuration, by positioning one cover member and the other cover member by the positioning portion, it is possible to prevent the relative misalignment between the two cover members adjacent to each other. In addition, one cover member and the other cover member can be easily positioned by a simple operation of inserting the protrusion into the insertion portion.

Further, in the present invention, a first surface portion is provided on the edge portion of the one cover member on the side of the other cover member, and the edge portion of the other cover member on the side of the one cover member is provided. A second surface portion is provided, and the one cover member and the other cover member are arranged so that the first surface portion and the second surface portion face each other, and the protrusion portion is provided on the first surface portion. It is preferable that the entry portion is provided on the second surface portion.

According to this feature configuration, when the one cover member and the other cover member are attached in a state where the first surface portion and the second surface portion face each other, the protrusion can be easily inserted into the insertion portion.

Further, in the present invention, it is preferable that the protrusion is formed of a plate-shaped portion, and the intrusion portion is formed of a notch or an opening.

According to this feature configuration, the protruding portion and the intruding portion can be simply configured.

Further, in the present invention, the one cover member and the other cover member are arranged in a state where a gap exists between the first surface portion and the second surface portion, and the first surface portion and the first surface portion are arranged. It is preferable that at least one of the two surface portions is provided with a gap hiding portion that hides the gap.

According to this feature configuration, the gap is hidden by the gap hiding portion. As a result, the inside of the side cover is not exposed to the outside of the side cover through the gap, and dust and the like are less likely to enter the inside of the side cover through the gap.

Further, in the present invention, it is preferable that the gap concealing portion is composed of the first surface portion or the portion extending from the second surface portion.

According to this feature configuration, the gap hiding portion can be simply configured.

Further, in the present invention, it is preferable that the gap concealing portion is provided on the same second surface portion as the entry portion.

Here, if the gap concealing portion is provided on the same first surface portion as the protrusion portion, when the protrusion portion is inserted into the entry portion in the state where the other cover member is attached, the protrusion portion is combined with the protrusion portion. Since the position of the gap hiding portion changes, the gap hiding portion easily interferes with the other cover member.

According to this feature configuration, when the other cover member is attached, the position of the gap concealing portion does not change when the protrusion is inserted into the insertion portion, so that the gap concealing portion interferes with one cover member. It's hard to do.

Further, in the present invention, it is preferable that the protrusion is provided at the end of the first surface portion and the entry portion is provided at the end of the second surface portion.

According to this feature configuration, by aligning the end portion on the first surface portion and the end portion on the second surface portion, the protrusion portion enters the entry portion. As a result, the protrusion can be easily inserted into the insertion portion.

Further, in the present invention, it is preferable that the intrusion portion is formed by a notch portion, and the protrusion portion is configured so as to be removable from the intrusion portion along the notch direction.

According to this feature configuration, by inserting and removing the protrusion with respect to the insertion portion along the notch direction, the protrusion enters the insertion portion and the protrusion exits from the insertion portion. As a result, positioning by the positioning unit and its release can be easily performed.

Further, in the present invention, a grain removal device is provided as the work device, and the side cover is detachably provided on the lateral side portion of the grain removal device, and is vertically divided into the plurality of cover members. The positioning portion is provided over two cover members vertically adjacent to each other among the plurality of cover members, and the cover member located on the upper side of the two cover members and the two cover members. It is preferable that the cover member located on the lower side is positioned, the protrusion is provided on the cover member located on the upper side, and the entrance portion is provided on the cover member located on the lower side. is there.

According to this feature configuration, by positioning the cover member located on the upper side and the cover member located on the lower side by the positioning portion, the relative misalignment between the two cover members vertically adjacent to each other is prevented. be able to. Further, the cover member located on the upper side and the cover member located on the lower side can be easily positioned by a simple operation of inserting the protrusion into the insertion portion from above.

Further, in the present invention, the cover member located on the upper side and the cover member located on the lower side are the lower edge portion of the cover member located on the upper side and the upper edge portion of the cover member located on the lower side. A gap concealing portion is provided on the upper edge portion of the cover member located on the lower side in a state where a gap exists between the gaps, and the gap concealing portion is a cover member located on the lower side. It is preferable that the cover member extends from the upper edge portion to the laterally inner position of the threshing device from the lower edge portion of the cover member located on the upper side.

According to this feature configuration, the gap is hidden by the gap hiding portion. As a result, the inside of the side cover is not exposed to the outside of the side cover through the gap, and dust and the like are less likely to enter the inside of the side cover through the gap. Further, the edge of the gap hiding portion is located laterally inside the threshing device with respect to the edge of the lower edge portion of the cover member located on the upper side. As a result, it is possible to effectively prevent the inside of the side cover from being exposed to the outside of the side cover through the gap.
