Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the treatment of leakage treated material leaking from a receiving net below the handling chamber and non-leakage treated material discharged from the dust inlet of the handling chamber. an oscillating sorting device that transports in one direction while oscillating sorting; a processing material amount detection means for detecting the amount of the leaked material; a vehicle speed changing means for changing vehicle speed; The present invention relates to a processing material amount adjusting device for a sorting section in a combine harvester, which is provided with a control means for operating the vehicle speed changing means to maintain the leakage processing material amount at a set amount based on information.

[Conventional technology]

In a general processing material amount adjustment device, the control means controls the harvesting if the amount of leakage processing material (mainly grains and grains with branches) detected by the processing material amount detection means is greater than a set value. By operating the vehicle speed changing means to reduce the vehicle speed at
Reduce the amount of waste material. Further, if the amount is less than the set value, the amount of leaked waste is increased by operating the vehicle speed changing means to increase the vehicle speed at the time of reaping. In other words, by increasing or decreasing the vehicle speed, the amount of leaked waste is controlled to be maintained at a set value.

[Problem to be solved by the invention]

In general, there is a proportional relationship between the amount of leaked material that leaks from the receiving net below the handling room and the amount of non-leaked material (mainly straw waste) that is discharged from the dust outlet at the rear of the handling room. If the amount of leakage treatment material is maintained appropriately, the amount of non-leakage treatment material is also maintained appropriately.

However, if the culm is wet, the receiving net becomes clogged and the amount of leaked material decreases, while the amount of non-leaked material increases, and sometimes the moist non-leaked material gets tangled and becomes clogged, preventing smooth flow. may not be able to be transferred to

The present invention has been made in view of this situation, and an object of the present invention is to remove the blockage and enable smooth transfer even if the non-leakage treatment material becomes clogged. It is said that

[Means to solve the problem]

In order to achieve the above object, the present invention is provided with a clogging detection means for detecting a blockage in the transfer of the non-leakage processing material, and a transfer means for increasing the transfer force of the non-leakage processing material, and the control means: The first characteristic configuration is that the transfer means is activated when the clogging detection means detects a clogging.

In addition, the second point is that the transfer means increases the amount of air blown by a winnowing machine that sends sorting air in the direction of transfer of the oscillating sorting device.
It has a characteristic configuration of

Furthermore, the third characteristic configuration is that the control means is configured to operate the vehicle speed changing means to change the vehicle speed to a lower speed side when the clogging detecting means detects the clogging.

[For production]

According to the first characteristic configuration, when the clogging detection means detects a blockage in the transfer of the non-leakage material, the control means operates the transfer means to increase the transfer force of the non-leakage material to prevent the blockage from occurring. be resolved.

According to the second characteristic configuration, in the first characteristic configuration, in order to increase the transfer force of the non-leakage processed material, the number of sorting winds of the winnower sent in the transfer direction of the swing sorting device is increased. Then, the wind power is used to unblock the transfer of non-leakable materials.

According to the third characteristic configuration, in the first and second characteristic configurations, when the clogging detection means detects the clogging, the control means operates the vehicle speed changing means to change the vehicle speed to a lower speed side. By lowering the vehicle speed, the amount of grain culm supplied into the handling room decreases, and the amount of straw waste discharged from the dust outlet also decreases.

〔Effect of the invention〕

In the first feature, even if a blockage occurs with non-leakage while the amount of leakage is maintained at a set value, the blockage can be cleared.

In the second characteristic configuration, since the winnowing machine provided in the combine harvester is used, it becomes possible to increase the transfer power of the non-leakage processed material with minimal modification and cost.

In the third characteristic configuration, in addition to increasing the transporting force of the non-leakage material, the amount discharged from the dust inlet is also reduced, so that clogging can be resolved quickly.
