Straw cutting device matched with combine reaping and binding machine

Abstract

The invention discloses a straw cutting device matched with a combine reaping and binding machine. The straw cutting device matched with the combine reaping and binding machine comprises a straw conveying channel arranged between a combine harvester and a straw binding machine and is characterized in that a straw discharging roller and the straw cutting device are installed in the straw conveying channel. The straw cutting device mainly comprises fixed cutters and a moving cutter, wherein the fixed cutters and the moving cutter are distributed perpendicular to the channel direction, the fixed cutters are fixedly installed on the straw conveying channel, and the moving cutter can move freely in guide rails on the two sides of the straw conveying channel and are driven by crank-link mechanisms at the two ends of the moving cutter. Straws are cut in the direction perpendicular to the conveying direction of the straws, movements of the straws cannot be disorganized, and the straws are made to pass through the conveying channel more smoothly to reach a binding machine straw inlet. Meanwhile, the device is simple in structure, easy to process, moreover, short in transmission chain, light in weight and small in size, and the cutting length of the straws can be changed through the adjustment of the rotating speed of a power input shaft.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a straw chopping device matched with a combine harvester and baler. Background technique [0002] At present, most of the combine harvesters and balers on the market in our country work separately, that is, after the combine harvester works, the baler is used to bundle the straw in the field. This not only wastes resources and time, but also re-rolls the land, which easily causes soil compaction, increases follow-up work, and is not conducive to rush harvesting during farming. The core of the combine harvester baler lies in the straw conveying channel between the grass outlet of the threshing device and the grass inlet of the baler. Because the straw is long, it is easy to be entangled in the conveying channel, forming a blockage, which seriously affects the working performance and working efficiency of the whole machine, and the too long straw is not conducive to returning...

Problems solved by technology

Because the straw is long, it is easy to be entangled in the conveying channel, forming a blockage, which seriously affects the working performance and efficiency of the whole machine, and the straw is too long to be unfavorable for straw returning to the field.
