Description

[Detailed description of the invention] (a) Industrial application field The present invention is an invention related to the drive speed change of a lodging pulling device among the pulling devices of a combine harvester.

(b) Prior art Conventionally, a lifting device that rotates the tines in a direction perpendicular to the direction of movement of the aircraft and a lodging and pulling device that rotates the tines in the same direction as the direction of movement of the aircraft are placed side by side.
The technique of simultaneously operating one gear shift lever is known.

For example, see Utility Model Application Publication No. 55-5773.

However, this conventional technique has a drawback in that the lodging and hoisting tines can only be driven at low speeds among the high and low speeds of the hoisting tines. Also, there was no forced lubrication pump installed.

(c) Problems to be solved by the invention The lodging pulling device is attached as an auxiliary means to the conventional lifting device for hoisting the grain culms that are intricately intertwined and lodging.

Conventional hoisting devices rotate the tines in a direction perpendicular to the direction of movement, and when the grain culms are flopped down due to wind, etc., they can be adapted to the grain culm by re-harvesting. However, if the culms are extremely long and are intricately intertwined and lodged, or if they are entangled and lodged without a direction due to overheating, the lifting performance will deteriorate. In these cases, a lodging and pulling device is used that rotates the tines in the direction of travel.

The lifting device also needs to increase the speed of the tines for culms that are in a normally standing state, and the machine must be operated at a high speed. It is also necessary to slow down the speed of the lifting tine.

The present invention enables the lodging and pulling tine 2 to be driven at all times in conjunction with the hoisting tine 4, and when the speed of the lodging and pulling tine 4 is changed, the speed of the lodging and pulling tine 2 can also be changed at the same time. A forced lubrication pump 27 is attached via a clutch device 29 to the other end of the horizontal shaft 25 on which the sprocket 23 of the lodging pulling tine 2 is provided.
It is possible to change gears and stop by operating the .

(d) Means for solving the problem The purpose of the present invention is as described above. Next, the configuration for achieving the purpose will be explained.

(f) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, by arranging the lodging and hoisting tines 2 directly at one end of the horizontal shaft 25, the lodging and hoisting tines 2 and the hoisting tines 4 are simultaneously driven by the operation of the hoisting shift lever 19, so that reaping can be started. At times, there is no need to separately operate the clutch of the lodging and lifting tine 2 and the clutch of the lifting tine 4.

Furthermore, unlike the conventional technology, the lodging and lifting tine 2 is not configured to rotate only when the lifting tine rotates at a low speed, but the sprocket 23 is attached directly to the horizontal shaft 25, so that the lifting tine 4 and It is possible to simultaneously drive the lodging and raising tines 2 and change speed.

Second, by providing the forced lubrication pump 27 on the horizontal shaft 25 after the speed has been changed by the pulling transmission case 61, the rotation speed of the forced lubrication pump 27 also changes, and accordingly, the forced lubrication Since the discharge amount of the pump 27 changes, the amount of lubricating oil discharged can be made in accordance with the speed of the lodging and raising tines 2 and the raising tines 4.

Third, a forced lubrication pump 2 is provided at one end of the horizontal shaft 25.
7 is arranged, and the drive of the forced lubrication pump 27 can be stopped at the same time by operating the lifting gear shift lever 19. Therefore, when the lifting operation is stopped, unnecessary lubricating parts are stopped. This eliminates the risk of dripping on the parts.

Fourthly, since a clutch device 29 is separately provided between the horizontal shaft 25 and the forced lubrication pump 27, the clutch lever 28 that operates the clutch device 29 can also be used to move the tine 2 or In the driving state of the lifting tine 4, the forced lubrication pump 2
It is possible to obtain a stopped state of only 7, which also prevents unnecessary dripping of lubricating oil.
