BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general-purpose combiner that drives a traveling device and a reaper in synchronization.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
T), an output side of an engine C is connected to an input shaft B of a transmission A having a main transmission mechanism A1 and an auxiliary transmission mechanism A2 via a traveling clutch D; The traveling device E is connected to the output side of the mechanism A2, and the PTO shaft F for cutting drive is linked to the output shaft M of the transmission A1 in the transmission A, and the PTO shaft F is cut via a cutting clutch G. While the transport device H1 and the scraping auger H2 of the section H are linked, the transport device H
1 and the input side of the scraping auger H2, the cutting reel H3 of the cutting unit H and the cutting blade H4 via the cutting blade / reel clutch I.
And are linked.

When the culm is harvested and threshed in a field or the like, the rotational power of the engine C is transmitted to the input shaft B of the transmission A by the engagement operation of the traveling clutch D, and the transmission A By operating the main transmission mechanism A1 and the auxiliary transmission mechanism A2, the traveling device E travels at a predetermined speed, and the PTO interlocked with the output shaft M of the transmission A1 with the engagement operation of the cutting clutch G. From the axis F, the transfer device H1 of the cutting section H and the scraping auger H
2 by rotating the cutting blade / reel clutch I at this time.
And power is transmitted to the cutting blade H4 so that the planted grain culm can be cut in synchronization with the vehicle speed by the cutting blade H4 while being scraped by the raking reel H3. It is transported to the threshing unit side via the device H1 and the scraping auger H2 to perform threshing.

When the above-mentioned general-purpose combiner enters a field, when the threshing process is performed on the culm by cutting the headland, the input shaft B of the transmission A is rotated by the engagement operation of the traveling clutch D. With the auxiliary transmission mechanism A2 of the transmission A held at the neutral position, the main transmission mechanism A1 is moved to the highest speed position, the cutting clutch G is engaged, and the cutting blade / reel clutch I
In a state where the scraping reel H3 and the cutting blade H4 are stopped by performing a cutting operation, the conveying device H1 of the cutting unit H and the scraping auger H2 are rotated at a high speed, and the scraping auger H2 is rotated. A headland cut culm is put into a platform to be installed, and is conveyed to the threshing unit side via the conveying device H1 and the scraping auger H2.

[0005]

However, as described above, in the general-purpose combiner in which the traveling device E and the reaping unit H are driven in synchronization with each other, threshing of the headland cut culm is performed. In this case, if the operation lever of the subtransmission mechanism A2 provided in the transmission A is erroneously operated from the neutral position to the work position, the traveling body moves, which is very dangerous.

An object of the present invention is to prevent the traveling body from moving even if the operating lever of the transmission is erroneously operated, for example, when threshing of a headland cut mow culm is performed. It is an object of the present invention to provide a highly secure general-purpose combine which can surely prevent the occurrence of a wastewater.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention comprises an input shaft which is connected to an engine via a traveling clutch, and changes the rotational power of the input shaft to provide a traveling device. Power transmission system between the engine and the traveling clutch, and power transmission between the cutting clutch and the cutting unit in a general-purpose combine in which a cutting unit is interlocked with the input shaft of the transmission through a first cutting clutch. A cutting drive system connected to the cutting drive system, and a second cutting clutch is interposed in the cutting drive system.

[0008]

In the general-purpose combiner described above, when performing the harvesting and threshing work of the grain culm, the rotational power of the engine is transmitted to the traveling device via the input shaft of the transmission and the internal transmission mechanism by the engagement operation of the traveling clutch. Also, by turning on the first cutting clutch in a state where the second cutting clutch is disengaged, the rotational power of the input shaft is reduced via the cutting drive system provided with the first cutting clutch. The harvested portion is transmitted to the reaping unit side, and the reaping unit is driven to cut the planted grain culm in the field, and the harvested grain culm is transported to the threshing unit side for threshing.

Further, when threshing of a head crop mowing culm or the like, the traveling clutch is disengaged to stop the mowing drive system in which the first mowing clutch is interposed, and the second mowing clutch is stopped. The rotation power of the engine is transmitted from the traveling clutch to the transmission through a cutting drive system in which a second cutting clutch of a different system from the cutting drive system on the first cutting clutch side is interposed. It is transmitted to the reaping unit from the second reaping clutch without reaching the position.Therefore, when the threshing process is performed on the headland cutting culm, the operation lever of the transmission is erroneously operated. However, the traveling device interlocked with the transmission is not driven, and therefore, it is possible to reliably prevent the traveling body from unexpectedly moving, resulting in excellent safety.
Moreover, the cutting unit is rotated at a high speed from the engine via the cutting drive system on the second cutting clutch side while reliably preventing the traveling machine body from unexpectedly moving during threshing of the headland cutting culm. This makes it possible to perform a good threshing process on the headland cut culm without clogging the culm in the cutting section.

When the first mowing clutch 11 is engaged in the engaged state, the rotational power of the engine 3 is transmitted through the first mowing drive system 17 to the traveling clutch 8 and the transmission 7.
The input shaft 73 and the cutting drive output shaft 74 interlocked with the input shaft 73 are transmitted to the cutting unit 5 side, and the transport device 53 and the scraping auger 54 of the cutting unit 5 are driven to rotate. When the cutting blade / reel clutch 12 is engaged, the scraping reel 55 and the cutting blade 56 are also driven, so that the planted grain culm in the field is scraped by the scraping reel 55 and the cutting blade 56 is driven by the cutting blade 56. The harvested culm is sent to the threshing unit 4 side by the transfer device 53 and the scraper orker 54, so that the harvesting is synchronized with the vehicle speed. In the threshing unit 4, the threshing rotor 41 is driven by the engagement operation of the threshing clutch 16, whereby the threshing rotor 41, the Karamin 42, the first and second conveyors 43 and 44, and the rocking sorter plate 45 are respectively driven.

The first product is dropped on the first conveyor 43 and taken out to the outside, and the second product is supplied from the second conveyor 44 to the threshing rotor 41 and reprocessed.

Further, when threshing a grain stalk or the like by cutting a headland when a general-purpose combine enters a field, the cutting blade / reel clutch 12 is disengaged, and the scraping reel 55 and the cutting blade 56 are disengaged. In a state in which the transporting device 53 and the scraping auger 54 of the cutting unit 5 are rotated at high speed, the headland mowing culm is thrown into the platform 52 in which the scraping auger 54 is installed, It is conveyed to the threshing unit 4 side via the conveying device 53 and the scraping auger 54. At the time of threshing of the headland-cutting grain culm, the traveling clutch 8 is disengaged to perform the first operation. When the second mowing clutch 19 is engaged while the mowing drive system 17 is stopped, the first mowing drive system 17 is stopped.
The rotation power of the engine 3 is not transmitted from the traveling clutch 8 to the transmission 7 side via the second harvesting drive system 18 of a different system from the second harvesting clutch 19 of the second harvesting drive system 18. It is transmitted to the conveying device 53 and the scraping auger 54 of the cutting unit 5, and therefore, when the threshing process of the headland-cutting grain culm is performed, the operation lever provided on the transmission 7 may be erroneously operated. However, the traveling device 2 interlocked with the transmission 7 is not driven, and therefore, it is possible to reliably prevent the machine body 1 from unexpectedly moving during the threshing process of the headland cutting culm. It will be excellent in safety. In addition, during the threshing process of the headland cutting culm, while the traveling machine 1 can be reliably prevented from moving unexpectedly, the traveling machine 1 is scraped from the transport device 53 via the second cutting drive system 18. It becomes possible to rotate the stuffing auger 54 at a high speed, and it is also possible to carry out a good threshing process of the corn cultivated corn culm without clogging the culm in the conveying device 53 and the scraping auger 54.
