2. Description of the Related Art Conventionally, in the above-mentioned combine, there is no means for detecting the amount of processed products in the handling chamber or the mass of processed products formed in the handling chamber, and the operator increases the amount of processed products. There was no choice but to know the formation of lumps of processed materials and processed materials from abnormal sounds in the handling room.

[0003]

According to the above-mentioned conventional structure, the operator has no choice but to know the increase in the amount of the processing object in the handling room and the formation of the lump of the processing object by the abnormal sound in the handling room. In addition, if there is no abnormal sound even if lumps are formed, or if the abnormal sound is small, or if the surrounding noise is large, continue to operate in the same state without noticing and leave the unhandled grain. It was easy to put out the lump of the processed product and to discharge the lump of the processed product as it was to lose the grain in the lump.

Further, the operator must always pay attention to the abnormal sound in the handling room, and it is difficult to concentrate on the driving operation, and there is room for improvement in terms of workability.

The object of the present invention is to prevent the unhandled grains from being left unhandled, to prevent the grains contained in the lump of the processed product from being discharged from the machine, and to improve the workability. To provide a combine.

According to the characteristic construction of the first aspect of the present invention, since the pressure sensor for detecting the pressure of the processing object in the upper part of the handling chamber is provided on the top plate of the handling chamber, the pressure sensor on the side of this handling plate is set. By exceeding the pressure, it is possible to know that the amount of processed material has increased and that a mass of processed material has been formed in the handling chamber and has been lifted to the top plate side. Further, since the pressure sensor for detecting the pressure of the processed matter discharged from the dust inlet is provided in the vicinity of the dust inlet, the pressure sensor on the dust outlet side exceeds the set pressure, It is possible to know that the amount of the processed material on the dust port side has increased and that the mass of the processed material has been discharged out of the handling chamber.

When both the pressure sensor on the top plate side and the pressure sensor on the dust inlet side exceed the set values, the control device drives the crawler traveling device so that the speed of the crawler traveling device decreases. Since the parts are controlled, the amount of grain culms to be taken into the handling chamber is reduced, and each grain culm can be sufficiently treated and processed in the handling chamber. As a result, it is possible to prevent the untreated residue from being left on the culm, the formation of a lump of the processed product containing the grain, and the discharge of such a lump as it is to the outside of the machine.

Further, since the pressure sensor or the like detects the situation in the handling room as described above, the operator can concentrate on the driving operation without paying attention to the situation in the handling room.

When only one of the pressure of the processed material in the upper part of the handling chamber and the pressure of the processed material discharged from the dust inlet exceeds the set value, the inside of the handling chamber is It is easy for the increase in the amount of processed material to recover, and
Since the lumps of the processed material are not easily loosened in the handling room and hinder the handling processing in the handling room, in such a state, the vehicle speed is not lowered and thus the work efficiency is not lowered.

According to the characteristic configuration of the second aspect of the present invention, only the first state in which both the pressure sensor on the top plate side and the pressure sensor on the dust inlet side exceed the set values, and only the pressure sensor on the top plate side. The display means is provided to notify the operator separately of the second state in which the value exceeds the set value and the third state in which only the pressure sensor on the dust inlet side exceeds the set value. Therefore, based on this display, the operator can It is possible to take appropriate measures such as lowering the vehicle speed as described above, reduce the amount of grain stalks to be taken in the handling room, sufficiently handle the grain stalks in the handling room, and process the grain stalks. It is possible to prevent the untreated material from being left unhandled, the formation of a lump of the processed material containing the grain, and the discharge of such a lump as it is to the outside of the machine. Also in the second aspect of the invention, since the pressure sensor or the like detects the situation in the handling room as described above, the operator can concentrate on the driving operation without paying attention to the situation in the handling room.

[0013]

As described above, according to the present invention, it is possible to prevent the unhandled grain culm from being left unhandled and to prevent the grain contained in the lump of the processed product from being discharged from the machine. Since the recovery rate can be improved and the operator can concentrate on the driving operation without paying attention to the situation in the handling room, it was possible to provide a combine that can improve workability.
