Combine-harvester

Abstract

The invention provides a supporting combine-harvester, including a frame, a drive framework, a spike feeding hollow frame linked with the drive framework and in turn installed on the frame, a threshing working house with with spike entrance and grain exit, a cutting knife a screening baffle capable of fully enclosing a grain-throwing fan and a sifting fan and a conveying trough, vertified threshing (harvesting) the grain at first and able to support cutting stalks. There is a sieve baffle able to realize full sealing and assorted with the spike entrance on the hollow frame; there is feeding groove on the grain exit. The knife tool can be installed behind the threshing working house and also behind the walking chassis.

Description

Technical field: [0001] The present invention relates to a harvester, in particular to a combine harvester. Background technique: [0002] At present, the combine harvesters used at home and abroad cut first and then beat, which consumes a lot of power and the power is too low; It is not conducive to farming in the second season of agriculture; the conveying capacity is large after cutting first, and the screening, winnowing, and grain storage boxes are very large. The grain loss rate of cutting before harvesting is high, especially for rice. When the farming is slack, several machines need to be parked, and the utilization rate is not high. The ability to overcome obstacles is poor, the weight is heavy, and the rice fields are easy to sink; the cost is high. It is impossible to return the stalk to the field at all, so it has to be burned, which brings a series of serious ecological and environmental pollution problems. Invention content: [0003] In view of the above re...

[0002] At present, the combine harvesters used at home and abroad cut first and then beat, which consumes a lot of force and the power is too low;

It is not conducive to farming in the second season of agriculture; the conveying capacity is large after cutting first, and the screening, winnowing, and grain storage boxes are very large. The grain loss rate of cutting first and then harvesting is high, especially for rice. When the farming is slack, several machines need to be parked, and the utilization rate is not high. Poor obstacle surmountability, heavy weight, easy to sink rice fields; high cost

It is impossible to return the straw to the field and has to be burned, which brings a series of serious ecological and environmental pollution problems
