Problems solved by technology

[0005] However, in a combine harvester that repeats high-speed movement between fields and low-speed harvesting, if the maximum vehicle speed is set based on the time of movement between fields, the vehicle speed will increase too much during the harvesting operation. The following problems are caused: the height adjustment of the harvesting device cannot be consistent with the unevenness of the farmland surface, and the harvesting device crashes into the farmland surface and is damaged; Turning becomes difficult, etc.
[0006] On the other hand, if the maximum vehicle speed is set as a standard during harvesting work, high-speed driving suitable for driving on the road cannot be performed, and it takes time to move between fields, resulting in a decrease in work efficiency.

Abstract

The invention relates to a combine harvester, wherein the variable speed of the vehicle is limited within the applicable range for farmlands and crops.Meanwhile, the operation of the combine harvester and the harvesting efficiency thereof are improved.The inclination angle of the inclined board of the hydraulic motor of a hydrostatic stepless speed change gear can be switched to a low-speed driving side or a high-speed driving side.When the inclination angle of the inclined board of the hydraulic motor is switched to the low-speed driving side, a maximum speed setting meter dial for the changing setting of the highest speed due to the high speed position of the gearshift is provided.Meanwhile, the maximum speed setting is available only when the inclination angle of the inclined board of the hydraulic motor is switched to the low-speed driving side.When the maximum speed is set and the inclination angle of the inclined board of the hydraulic motor is switched from the low-speed driving side to the high-speed driving side, the maximum speed setting set by the meter dial is unavailable.

Description

technical field [0001] The present invention relates to combine harvesters. Background technique [0002] Conventionally, there is known a combine harvester in which a threshing device and a grain box are arranged side by side on the upper side of a traveling device driven by a hydrostatic continuously variable transmission for traveling, and a control unit is provided on the front side of the grain box. , the harvesting device is set on the front side of the control part and the threshing device, and the gear lever for changing the inclination angle of the pump swash plate, that is, the swash plate of the hydraulic pump of the hydrostatic continuously variable transmission device for travel, is set. [0003] In addition, as disclosed in Patent Document 1, in a work vehicle having a traveling device driven by a hydrostatic continuously variable transmission for traveling, there is known a technique in which a dial for setting a maximum vehicle speed is provided. The fixed d...
