Wheel harvester supporting straw baler

Abstract

The invention discloses a straw baler matched with a wheeled harvester, aiming at solving the problems of high cost, easy grass entanglement and high failure rate of the existing combine harvester. The invention includes a harvester and a baler installed on the harvester. A drum shaft is arranged on the harvester, and a driving sprocket is connected to the drum shaft by several fastening screws. The baler includes a baling box, a reducer, a transmission mechanism, Grass feeding box, grass puller, longitudinal grass presser, knotter, and baling box are arranged inclined upwards from front to back. The upper end of the baling box is near the front position. There is a piston in the baling box, the front end of the piston is movably connected to the push rod, the upper end of the piston is connected to the front moving knife near the rear edge, and the fixed knife corresponding to the front moving knife is connected to the rear edge of the material inlet on the baling box. The blade of the movable knife has a linear structure, and the blade of the fixed knife has a serrated structure.

Description

technical field [0001] The invention relates to a harvester, more specifically, it relates to a high-efficiency wheeled harvester matching straw baler. Background technique [0002] In the rice and wheat harvest season, in order to improve work efficiency, automated harvesting equipment has been adopted in many places to replace the traditional manual harvesting method. The use of combine harvesters in automated harvesting equipment is very common, but at present, after many combine harvesters have harvested rice and wheat, the straw is scattered in the field, and it is very troublesome if it needs to be recycled. At present, there are also straw collection and bundling machines specially used for straw recycling. There are two types of commonly used mechanical equipment. One is the traction straw picking and bundling machine. The other is a self-propelled straw harvesting and bundling machine, which has its own power and is equipped with a header and a crushing device. It ...

AI Technical Summary

Problems solved by technology

[0003] The invention overcomes the following shortcomings of the existing combine harvesters: the traditional rice and wheat harvester can only harvest the rice and wheat but cannot bundle the straw, and needs to use a special straw bundler for secondary work. Large investment, high operating cost, and low work efficiency; the existing wheat and rice combine harvester is connected to the baler drum wheel with poor reliability, and there is a gap between the top of the drum shaft and the drive sprocket of the drum wheel, which makes the drive sprocket It is easy to sag and fall off the chain, and the roller wheel is easy to break; during the operation of the reducer, the phenomenon of straw entanglement is easy to occur in the gap between the power input sprocket, the power output sprocket, the drive disc and the reducer. The disk stops running, which will damage the reducer and the baler; the moving knife on the piston and the fixed knife matched with it are flat knives, and the vibration generated when cutting the straw is large, which affects the stable operation of the piston and increases the failure rate.
