Description

[Detailed Description of the Invention] The present invention relates to an internal structure of a feed port in a feed section of a threshing machine.

In other words, the truncated cone at the end of the handling barrel is installed so that it can be seen above the net holding plate that extends from the lower part of the supply opening at the lower side of the handling room to the inside of the handling room and is connected to the crimp net. In the feeding section of a threshing machine that is configured to be installed and handled, it is possible to effectively prevent grain culm rods and weeds from getting caught by straddling from the outside to the inside at the abutting end of the feeding port, as in the past. Therefore, the grain culm supplied from the supply port can be reliably and satisfactorily threshed without being caught, and the present invention has a simple structure and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a front view of a part of the threshing machine mounted on a combine harvester.
A straw trap 7 is installed horizontally, and a supply port 2 is provided at the entrance side plate 8 at the bottom of one side of the handling chamber 1, and a straw discharge port 10 is provided at the outlet side plate 9 at the bottom of the other side. A crimp net 3 stretched over the lower part of the handling chamber 1 is attached to the end of the net holding plate 4 that extends short from the lower part of the forming waist supply opening 2 to the inner side of the handling chamber 1.
A cutting blade 12 is fixed to a support frame plate 11 installed horizontally at the rear of the handling chamber 1, and the supply plate 1 is installed outward from the bottom of the supply port 2.
3 is extended and configured in the same way as the conventional type.

Inside the handling chamber 1 is a handling barrel A having a truncated conical portion a on one end side.
is mounted on a shaft in the same manner as the conventional structure, and five groups of normal handling teeth are implanted on the peripheral surface of the handling cylinder A corresponding to the crimp net 3, and the net holding plate 4 is
A handling tooth 5b that is slightly shorter than the normal handling tooth 5 is implanted on the circumferential surface of the truncated conical part a corresponding to the truncated conical part a, and a small handling tooth curved in a U shape is installed on the peripheral surface of the distal end side of the truncated conical part a. 5a is implanted so that its tip approaches the inner surface of the inlet side plate 8.

The extending portion of the net presser plate 4 from the inner side of the abutting end portion 2a of the supply port 2 to the rear side inside the handling chamber 1 has a distance from the tip of each handling tooth 5a, 5b in the truncated conical portion a. The back side net holding plate 4a is stretched so that there is a predetermined interval that is approximately the same as the interval between the crimp net 3 and the tip of the normal handling tooth 5.
The front and back of the board 4a are connected to the net holding board 4 and the support frame board 11,
Both sides are connected to the entrance side plate 8 and the crimp net 3, respectively, and are installed so as to be inclined.

Therefore, during the threshing operation, the grain culm is supplied from the supply port 2, and the truncated conical part a of the handling barrel A and the handling teeth 5a and 5b around it are rectified and threshed to prevent grain breakage. Then, the grain can be threshed by the handling teeth 5 of the handling cylinder A.

In that case, during feeding, frame pieces of grain culms and weeds may get caught astride the abutting end portion 2a of the feeding port 2;
The handling teeth 5a and 5b rotating inside the terminal end 2a come very close to the back net holding plate 4a, so the handling teeth 5a and 5b pull the frame pieces and weeds from the bottom to the top to prevent them from getting caught. It will be removed so that it is not present and supplied into the handling room 1 as it is.

In this way, the present invention has a handling barrel A end located above the net holding plate 4 which extends from the lower part of the supply port 2 opened in the lower part of one side of the handling chamber 1 to the inner side of the handling chamber and is connected to the crimp net 3. In the supply section of the threshing machine, which is installed so that the truncated conical part a of the threshing machine is exposed and configured for lower handling, there is a net holding plate extending from the inner side of the abutment end part 2a of the supply port 2 to the rear side of the handling chamber. 4, each handling tooth 5a, 5b in the truncated conical part a of the handling cylinder A is provided.
The front and back of the back side net holding plate 4a are attached to the net holding plate 4 and the support frame plate 11 so that the distance from the tip of the crimp net 3 to the tip of the normal handling tooth 5 is approximately the same as the distance between the crimp net 3 and the tip of the normal handling tooth 5. Since both sides are connected to the inlet side plate 8 and the crimp net 3 and stretched at an angle, the back side net holding plate 4a is firmly stretched and the distance between the tips of the handling teeth 5a and 5b is always maintained at a predetermined distance. The teeth 5 of the truncated conical part a are used to remove frame pieces, weeds, etc. that are kept at a certain distance from each other and try to get caught by straddling the abutting end 2a of the supply port 2.
By pulling the nets a and 5b from bottom to top in the direction of the back net holding plate 4a, it is possible to prevent the net from getting caught, and it is possible to smoothly feed the net from the supply port 2 without getting caught. It is possible to perform good feeding without causing ear breakage, and has the advantage that it can be suitably implemented with a simple structure.
