Embodiment Construction

[0047] Below, based on the accompanying drawings ( Figure 1 ~ Figure 3 ) describes an embodiment that actualized the invention of the present application. figure 1 is the left side view of the combine harvester, figure 2 is its right side view, image 3 is its floor plan. First, refer to Figure 1 ~ Figure 3 The schematic structure of the combine harvester is demonstrated. In addition, in the following description, facing the advancing direction of the traveling body 1, the left side is simply called the left side, and the right side is simply called the right side facing the advancing direction.

[0048] Such as Figure 1 ~ Figure 3 As shown, the common type combine harvester in embodiment is equipped with the traveling body 1 supported by the right and left pair of crawlers 2 made of rubber crawlers as a running part. At the front part of the traveling body 1, a single-acting lifting hydraulic cylinder 4 can be used for lifting and adjusting, and a harvester for harv...

Abstract

The purpose of the present invention is to provide a combine whereby left / right travel units (2) can be evenly braked, malfunctioning of the left / right travel units (2) can be reduced, and braking performance of the left / right travel units (2) can be enhanced. This combine is provided with a reaper device (3), a threshing device (9), and a traveling chassis (1) loaded with an engine (7). Left / right travel units (2) are mounted onto the traveling chassis (1). The engine (7) actuates the travel hydraulic pump (65) and left / right travel hydraulic motors (69) are driven by the travel hydraulic pump (65), while in turn left / right brakes are provided to each of the left / right travel hydraulic motors (69). The combine is also provided with left / right brake levers (296) for respectively braking left / right brake mechanisms (297), and with a stabilizer body (286) for braking operations, the stabilizer body being coupled to the brake operation tool (38) via the brake wire (278). The configuration allows for the left / right brake levers (296) to be evenly towed by the stabilizer body (286) for braking operations.

Description

technical field [0001] The invention of this application relates to a combine harvester equipped with a harvester for harvesting unharvested grain stalks in a field, and a threshing device for threshing harvested grain stalks. Background technique [0002] In the past, there has been a technology of continuously harvesting and threshing unharvested grain stalks in the field, which includes: a traveling body with a traveling part and a driver's seat, a harvesting device with a harvesting knife, a threshing device with a threshing drum, from The harvester feeds the harvested grain stalks to the threshing device, the engine that drives each part, the grain sorting mechanism that sorts the threshed products of the threshing device, and the grain box that collects the grains of the threshing device (Patent Document 1) . Also, a technique is known in which a hydraulic transmission having a traveling hydraulic pump and a traveling hydraulic motor is provided, and the crawler is dr...
