Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a lifting device for a threshing section in a combine for threshing and sorting grain culms.

(B) Conventional technology Conventionally, the fried food cylinder that leads to the most gutter is erected almost vertically, and the throwing cylinder of the second reduction thrower is tilted forward and the second food is returned to the handling room. What I did
It is already known from Japanese Patent Publication No. 57-62737, and a second reducing cylinder with a lifting body as a spiral is installed inside the machine (inside the machine) by vertically arranging the lifting cylinder along the outside of the handling room. Japanese Patent Application Laid-Open No. 52-47465 has already disclosed a device in which the discharge port is provided and inclined toward the front and the discharge port is opened above the rocking sorting body.

(C) Problems to be solved by the invention Among the above-mentioned known threshers, in the former, the second reducing means is a thrower type, and the second thing is thrown up by the jumping blade in the casing at the lower end of the throwing cylinder. Since it is guided and returned by a cylinder, when cutting and threshing a wet grain culm, a second product is likely to adhere to the throwing cylinder and become clogged.Therefore, the mowing and threshing work should be interrupted occasionally to remove the jam. Therefore, the work efficiency is significantly reduced. Further, since the second product is returned to the handling room, the handling barrel load is increased and the threshing treatment capacity is poor.

Further, in the latter, since the second reducing means has a spiral system, the second reducing cylinder is not clogged even when the leaked grain culm is threshed.

However, since the entire second reducing cylinder is disposed so as to face the inside of the sorting air passage inside the machine body, there is a drawback that the sorting wind becomes turbulent around the second reducing cylinder and the sorting performance is deteriorated.

(D) Means for Solving the Problems In the invention of the present application, the swing sorting body 25 is installed in the sorting chamber provided below the handling chamber 12 of the threshing apparatus 1 and behind the handling chamber 12, and the swing sorting body 25 is installed. The first transfer helix 28a is disposed below the first selection net 29 provided in the first transfer net 28a, and the fried grain cylinder 46 whose upper end communicates with the grain tank is substantially vertical at the transfer end of the first transfer helix 28a. While standing upright, a second transfer spiral 30a having a transfer end on the same side as the first transfer spiral 28a is disposed behind the first transfer spiral 28a, and a spiral is provided at the transfer end of the second transfer spiral 30a.

The side plate 56 on the side where the frying cylinder 46 and the second reducing cylinder 47 of the sorting chamber are provided so as to be narrower than the width of 12 is displaced inward from the side plate of the handling chamber 12, and the second reducing cylinder 47 is set to the above. Along with the side plate 56 that is displaced inwardly, the side plate 56 is tilted upward and upward along the side plate 56, and the second reducing cylinder 47 is located below the handling chamber 12 and the frying cylinder 46 and the above. It is configured so as to pass through between the side plates 56 and intersect with the base side of the fried food cylinder 46, so that the second reducing cylinder 47 is further forward of the fried food cylinder 46 along the outside of the side plate 56. The above-mentioned problem is solved by extending the discharge port 47d of the second reduction cylinder 47 from the side toward the transfer start end side from the first sorting net 29 on the swing sorting body 25 by extending to the second reducing cylinder 47. did.

(E) Action The grains in the object to be sorted which have leaked from the receiving net 24 of the handling chamber 12 onto the swinging sorting body 25 are transferred from the first sorting net 29 to the first receiving trough 28 and transferred the most. It is carried out to the outer side by the spiral 28a, and is then fed by the spiral-type lifting cylinder 46 into the grain tank 7.

In addition, the second one that fell into the second trough 30 is the second transfer spiral 30a.
Is transferred to the second reducing cylinder 47 on the outer side, and is obliquely moved forward and upward by the installed spiral to be reduced onto the rocking sorting body 25 for re-sorting processing.

At that time, the second object can be reduced by the spiral second reduction cylinder 47 without causing clogging, and the swing sorting body
By directly throwing and returning to the upper part of 25, it is possible to prevent an increase in the load of the handling cylinder and to enhance the threshing treatment capacity.

In addition, the second reducing cylinder 47 is passed between the fried food cylinder 46 and the side plate 56 of the sorting section to intersect with the fried food cylinder 46, and the second reducing cylinder 47 is extended further forward than the fried food cylinder 46. The second grain is thrown and returned from the first sorting net 29 on the rocking sorting body 25 to the transfer start end side, so that the grains in the second grain are again leaked and sorted by the first sorting net 29. It is surely collected in the first gutter 28.

Moreover, by bringing the second reducing cylinder 47 close to the side plate 56 of the sorting section which is displaced inward from the side plate of the handling chamber 12, the second reducing cylinder is
Even if the frying cylinder 46 is erected on the outside of the 47 and crosses it, the width of the fuselage does not become wide, and the number 2 from the upper end of the spiral installed in the No. 2 reducing cylinder 47 to the side plate 56 is not increased.
