Two-type combine harvester

Abstract

The invention provides a two-type combine harvester comprising a support, two groups of grain lifters, a vertical conveying chain, a rice reaping device, a grain reel, a horizontal conveying chain, a threshing unit and a transmission mechanism. A main travelling wheel and an auxiliary travelling wheel matched with the same in use are arranged on two sides of the bottom respectively, and are connected with each other to travel through a caterpillar track. The rice reaping device comprises an upper reaper and a lower reaper which are mounted on the support, the threshing unit is mounted on the support and comprises a barrel, a threshing cylinder is arranged inside the barrel, and a screw conveyer, and an air blower and a vibrating screen shaft are arranged at the bottom of the barrel. The two-type combine harvester has the advantages of simple structure, low cost, convenience in maintenance, good threshing effect, capability of harvesting laid rice and the like; production cost of the two-type combine harvester is only one fifth of that of combine harvesters imported from Japan, a quarter of that of domestic head-feed harvesters and two thirds of that of domestic full-feeding harvesters, so that purchasing burden of farmers is reduced greatly.

Description

technical field [0001] The invention relates to a harvester. Background technique [0002] Existing harvester has two kinds, and a kind of is semi-feeding type combine harvester, and another kind is full-feeding type combine harvester, and these two kinds of harvesters have advantages and disadvantages respectively, and full-feeding type combine harvester threshing The effect is good, but it is not suitable for harvesting lodging rice; the semi-feeding combine harvester cuts low stubble and can harvest lodging rice, and there are few failures of kawo straw during the transportation of rice, but its threshing effect is not good, and the existing semi-feeding combine Feeding combine harvesters and full-feeding combine harvesters are complex in structure and high in cost, and ordinary farmers cannot afford them. Contents of the invention [0003] The purpose of the present invention is exactly to provide a kind of advantages of half-feeding type combine harvester and full-fe...

AI Technical Summary

Problems solved by technology

[0002] There are two kinds of existing harvesters, one is a half-feed combine harvester, and the other is a full-feed combine harvester. These two harvesters have their own advantages and disadvantages. The full-feed combine harvester threshing The effect is good, but it is not suitable for harvesting lodging rice; the semi-feeding combine harvester cuts low stubble and can harvest lodging rice, and there are few failures of kawo straw during the transportation of rice, but its threshing effect is not good, and the existing semi-feeding combine Feeding combine harvesters and full-feeding combine harvesters are complex in structure and high in cost, and ordinary farmers cannot afford them
