Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention comprises a traveling device, and a swinging selection structure for selecting the handling room and the goods to be unloaded from the handling room, which are vertically arranged. In a threshing thresher that is equipped with a threshing sorting unit and has a mowing unit in front of the threshing sorting unit to mitigate and thresh the planted grain culm with the forward movement of the machine body, it is returned to the handling room for reprocessing. The present invention relates to a second reduction stop device.

(B) Conventional technology In the above-mentioned cutting and threshing machine, a conventional one having a structure for stopping the return of the second product to the handling chamber is disclosed in, for example, Japanese Utility Model Publication No. 49-26134. It is known.

However, according to what is described in this publication, in cooperation with the tilting of the threshing selection section during the rounding operation during the cutting operation, the unloaded material from the handling room is blocked on the swing selection plate. There is. In addition, the whole amount of the waste handled from the handling room comes to be blocked on the rocking sorting plate, and even the first product that must be sorted and taken out of the machine is stagnate on the rocking sorting plate. It ends up.

(C) Problems to be solved by the invention Thus, in the conventional configuration, the sorting plate for swinging the unhandled goods from the handling room is interlocked with the tilting of the threshing sorting unit during the traveling during the cutting operation. Although it is tried to prevent the above, the grain flow rate does not always decrease not only when the aircraft is traveling, but also at the end of mowing work, etc. Depending on the selection, the rate of falling into the second trough will increase, and it will circulate in the handling chamber and come off, causing damaged particles.

Also, in the conventional type, all the items to be handled from the handling room are blocked on the swing sorting plate, and even the first item that must be sorted and taken out of the machine is also placed on the swing sorting plate. It has the drawback of stagnation.

Therefore, in the present invention, the drawbacks of the conventional ones are eliminated, and the return of the second product to the handling chamber is stopped not only when the machine is traveling, but also when the grain flow rate is reduced. West,
Moreover, the reduction stop has been devised for the purpose of continuing the removal of the first product from the machine regardless of the first product.

(D) Means for Solving the Problems Therefore, in order to achieve the above-mentioned object, the present invention vertically arranges a handling room and an oscillating sorting structure for selecting a handling article from the handling room on a traveling device. In the cutting threshing machine for cutting and threshing the planted grain culm with the forward movement of the machine by mounting a threshing selection unit arranged in the front of the threshing selection unit, the grain in the handling chamber A sensor for detecting the presence or absence of culms is provided, and by detecting the absence of culms of the sensor, the second object falling from the oscillating selection structure to the second object receiving gutter is temporarily stored in the oscillating selection structure. Of.

(E) Action When the cutting threshing machine configured in this way is moved forward by the traveling device, the planted grain culms are mowed at the mowing section, and the mowed grain culms are supplied to the handling room for threshing and threshing by threshing. The wholesale goods are received by the lower swing sorting structure and sorted by the swinging action and the sorting wind, the first one is taken out of the machine, and the second one falls into the second one trough and is stored in the handling room. It is returned and reprocessed. In this case, the sensor always detects the presence or absence of grain culms in the handling room, and if there are grain culms, stores the second product in the rocking sorting structure as described above. Without dropping the grain into the handling room and returning it to the handling room, when the grain culm is exhausted, the second one is temporarily stored in the rocking sorting structure and the second one is transferred from the handling trough to the handling room. The reduction is stopped and the reprocessing of the second product is interrupted.

In a cutting threshing machine that is equipped with a mowing unit in front of the threshing selection unit to mitigate and thresh a planted culm with the advance outside the machine, a sensor that detects the presence or absence of culms in the handling chamber is provided. , When the sensor detects that there is no grain culm, it falls from the oscillating sorting structure to the second object receiving gutter 2
Since the food is temporarily stored in the swing selection structure, the sensor constantly detects the presence or absence of grain stalks in the handling room, and when there is a grain stalk, the second product is oscillated and sorted. It is dropped into the second trough and stored in the handling room without being stored in
When the grain culm becomes empty, the second product is temporarily stored in the rocking sorting structure by detecting this, and the return from the second product trough to the handling room is stopped and the reprocessing of the second product is interrupted. Therefore, it is possible to stop the return of No. 2 to the handling room if the grain flow rate is reduced, not only when the machine is traveling during the mowing work.
The rate of falling to the second trough increases due to the decrease in the grain flow rate. The second article is not circulated in the handling room, and the occurrence of shedding and damaged grains is not seen, and the reduction stop is the first article. Irrespective of the above, the removal of the No. 1 product from the aircraft has been continued.
