Problems solved by technology

[0003] In the above-mentioned existing structure, the belt transmission mechanism linking the intermediate shaft and the harvesting knife drive box is equipped on the lateral outside of the harvesting section, so the driving of the harvesting device A large number of components are required in the system, resulting in high cost
In addition, due to the friction transmission through the transmission belt, there may be transmission slippage caused by wear or elongation of the transmission belt, which will reduce the cutting performance of the harvesting device, so the maintenance of the transmission belt must be fully carried out.

Embodiment Construction

[0072] (summary of combine harvester)

[0073] Fig. 1 has shown the whole side of common type combine harvester of the present invention, and Fig. 2 has shown its whole top surface. This combine harvester is equipped with an axial flow type threshing device 3 and a bagging type grain recovery part 4 side by side on the traveling body 2 equipped with a pair of left and right crawler belt traveling devices 1, and the grain recovery part 4 The front of is equipped with driving part 5. In the front part of the threshing device 3, a feeder 6 for conveying harvested straw is connected in a manner to swing freely around the fulcrum P up and down, and a feeder 6 having a harvesting width approximately equivalent to the lateral width of the machine body is connected to the front end of the feeder 6 . The harvesting section 7 is equipped with an engine 8 laterally below the driving section 5 .

[0074] A hydraulic cylinder 9 is erected between the front part of the traveling body 2 an...

Abstract

The present invention can simplify the driving system of the harvesting device, and can reliably drive the harvesting device without special maintenance work. The intermediate shaft (65) is equipped with a rotation conversion mechanism (70) that converts the rotation of the intermediate shaft (65) around the lateral axis into reciprocating rotation around the axis in the front and rear directions, and transmits the converted reciprocating rotation power. The transmission shaft (74) extends forward, and the front end of the transmission shaft (74) is linked to the harvesting device (12).

Description

technical field [0001] This invention relates to the combine harvester provided with the harvesting part provided with the clipper type harvesting device, the screw conveyor for horizontal feed, and the rake drum at the front end of the feeder connected to the front part of a threshing apparatus. Background technique [0002] As a reaping part drive structure in the said combine, the structure disclosed, for example in Unexamined-Japanese-Patent No. 2005-211010 is known. That is, the power output from the intermediate shaft on the back of the harvesting section from the horizontal frame is transmitted to the harvesting knife drive box near the lateral side of the harvesting device via the transmission belt, and the harvesting knife drive box and the harvesting device are connected in linkage, and output from the intermediate shaft The power drives the screw conveyor and the raking drum. [0003] In the above-mentioned conventional structure, the belt transmission mechanism ...
