Straw baler matched with wheel type harvester

Abstract

The invention discloses a straw baler matched with a wheel type harvester. The defects that an existing combined harvester is high in cost, prone to being entangled with straw and high in fault rate are overcome. The straw baler comprises the harvester and a baler body arranged on the harvester, a roller shaft is arranged on the harvester, and the roller shaft is connected with a drive chain wheel through a plurality of fastening screws. The baler body comprises a baling box, a speed reducer, a transmission mechanism, a straw conveying box, a straw shifting device, a longitudinal straw pressing device and a twine knotter, the baling box is arranged by inclining upwards from front to back, a material inlet is formed in the position, close to the front portion, of the upper end of the baling box, a material outlet is formed in the rear end of the baling box, a piston is arranged in the baling box, a push rod is movably connected with the front end of the piston, front movable cutters are connected with the edge, close to the rear portion, of the upper end of the piston, fixed cutters correspondingly matched with the front movable cutters are connected with the rear edge of the material inlet in the baling box, blades of the front movable cutters are of a linear structure, and blades of the fixed cutters are of a sawtooth-shaped 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.
