Description

[Detailed description of the invention] (a) Industrial application field This invention relates to the structure of the starting end of a straw presser cover case of a threshing machine.

(b) Conventional technology Conventionally, a cover case has been placed above the straw holding table, which is installed opposite to the feed chain placed on the side of the threshing machine, from the starting end to the ending end. The starting end of the case, that is, the front part of the cover case corresponding to the entrance of the grain culm is open.

(c) Problems to be solved by the invention Thus, in the front part of the conventional cover case, the wind from the handling room and the dust from the grain culms being transported are blown up from the starting end of the case, and depending on the direction of the wind, There was a risk of spraying in the direction of the worker, and there was also a risk of the user's hand slipping and getting his or her fingertips caught between the straw presser and the cover case.

(d) Means for solving the problem In this invention, in the cover case that covers the straw presser of the threshing machine, a notch is provided in the front wall hanging down from the starting end of the cover case to allow the straw presser to rise. It is an object of the present invention to provide a starting end structure of a straw presser cover case for a threshing machine, which has a rubber sag hanging down from the notch.

(E) Function In this device, when carrying out threshing work while carrying grain stalks between a straw presser and a feed chain, a cover case is placed above the straw presser to prevent the handling room from being closed. In addition, the front wall and rubber sag at the starting end of the cover case prevent dust, etc. from blowing up from the starting end of the cover case, and prevent the grain from being threshed and transported. Even if the straw presser moves up and down depending on the amount of culm, the straw presser moves up and down while pushing away the rubber drippings in the notch provided in the front wall of the starting end of the cover case. Both the closing of the section and the vertical movement of the straw presser can be performed without any problem.

(f) Effects According to this invention, the rubber sag covers the notch in the front wall of the cover case, so wind, dust, etc. from the handling room are not blown up, and moreover, the fingertips are not placed inside the cover case. It is safe, and there is no risk of the straw presser becoming loose, and when the straw presser is raised and lowered, the rubber sag is pushed up or sagging in the notch in the front wall, so there is no problem in raising and lowering the straw presser This has the effect of closing the open part of the starting end of the cover case.

(G) Example The example of the present invention will be explained in detail based on the drawings.
A shows a combine harvester as a type of threshing machine, with a reaping section 1 at the front and a threshing section 2 at the rear.
A sorting section 3 is provided below, and a running section 4 is provided at the bottom.
The harvested grain culm is threshed in the threshing section 2, and the grain is sorted in the sorting section 3.
The structure is such that fine grains are obtained by sorting the grains.

Reference numeral 5 indicates a waste straw processing section attached to the rear of the sorting section 3.

The threshing section 2 has a handling drum 7 rotatably mounted on a shaft in a handling chamber 6, and a feed chain 8 with an upward slope from the front to the rear is arranged on the side of the handling drum 7.
A straw presser 9 is disposed above the feed chain 8 and along the feed chain 8.

The straw holding stand 9 is formed into a longitudinal shape with a substantially inverted U-shape in cross section, and is supported by a stand support rod 10 fixed to the machine frame via a connecting rod 11 so as to be vertically movable.
A spring 12 surrounding the periphery of the straw presser 9 is interposed between the table support rod 10 and the straw presser 9, and the spring 12 urges the straw presser 9 downward. Chain 8 and straw presser 9
Depending on the amount of grain culms to be held and conveyed between them, the straw holding table 9 rises against the bias of the spring 12, so that the grain culms can be reliably held and conveyed.

Moreover, a cover case 14 is provided above the straw presser 9 and located on the side of the handling chamber cover 13 of the handling chamber 6. It covers the side surface of the straw holding table 9 as well as the upper part of the table 9, and the base end part, that is,
The cover is constructed so that it can be rotated upwardly around a portion adjacent to the handling chamber cover 13.

At the starting end of the cover case 14, there is a front wall 1.
5 is vertically installed, and the front wall 15 has a rectangular notch 16.
is provided so that the straw presser 9 can be raised without any trouble by entering into the cutout 16, and a rubber drip 17 is hung from above in the cutout 16 to raise the straw presser 9. It extends to the top.

The starting end 9' of the straw presser 9 is provided to protrude forward from the front wall 15 of the cover case 14 in a slightly curved manner, so that the straw presser 9 and
The structure is such that there is no gap between the front wall 15 and the rubber sag 17 between the starting end of the cover case 14, and the vertical movement of the straw presser 9 is controlled by the notch 1.
6, the notch 16 is closed by the rubber sag 17 irrespective of the vertical movement of the straw presser 9.

Note that the rubber dripping 17 is located at the notch 16 of the front wall 15.
In addition to the case where the straw holding table 9 is provided in a closed state, the starting end of the straw holding table 9 is completely open, and instead of the front wall 15, a rubber drip 17 is arranged on the entire surface.
It is also possible to perform the function of the front wall 15.

In addition, the inner thickness of the rubber sag 17 is gradually thinned toward the lower end, so that the straw presser 9 can be moved up and down smoothly, and it can be adjusted to the vertical movement of the straw presser 9 to accurately align the starting end of the cover case 14. It is also possible to close the open part (see Fig. 3).Furthermore, the rubber sag 17 can be cut into vertical strips to better adapt to the vertical movement of the straw presser 9. (See Figure 4).

Reference numeral 18 indicates a bolt that fixes the upper edge of the rubber sag 17 to the inner upper edge of the front wall 15 of the cover case 14.

Reference numeral 19 indicates a grain culm carrying portion for holding the grain culm between the feed chain 8 and the straw holding table 9, and 20 indicates a gap serving as a grain culm transfer path.

Claims (1)

[Scope of utility model registration request] In the cover case 14 that covers the straw presser 9 of the threshing machine A, a notch 16 for lifting the straw presser 9 is formed in the front wall 15 hanging down from the starting end of the cover case 14, and a notch 16 for raising the straw presser 9 is formed. This is the starting end structure of a straw presser cover case for a threshing machine, which has a rubber sag 17 hanging down from 16.
