Threshing mechanism and reaping machine using same

Abstract

The invention discloses a threshing mechanism and a reaping machine using same; the threshing mechanism comprises a slant airpipe; the upper part of the airpipe is connected with a grain-collecting chamber; an air channel of the airpipe is blanked off by an air return plate, thus forming a tail wind channel and a headwind channel; the inner entrance end of the tail wind channel is provided with a wind wheel and a grass-removing rod corresponding to the wind wheel; blade edge of the wind wheel is teeth-shaped; the wind wheel and the grass-removing rod operates correspondingly and matches with each other to carry out threshing; the exit end of the headwind channel is provided with air holes which are located at the slant upward side or the front of the grass-removing rod. The reaping machine of the invention has the following advantages: 1. rough threshing, no grains omitted in straws; 2. thorough separation, grain is completely separated from abortive grain and grass-blade; 3 the whole machine is small and lightweight and is easy to operate; two people are enough to move the machine with ease in field paths and one person is enough to accomplish reaping of the grain, as a result, the machine is applicable to mountain area and hills; 4. the machine has complete functions by integrate self-moving, threshing, separation, cutting and loading in one single one machine.

Description

technical field [0001] The invention belongs to agricultural machinery equipment, and relates to a threshing device and a harvester using the device, in particular to a harvester integrating cutting, threshing, separation and collection. technical background [0002] Along with the development of science and technology and the continuous improvement of agricultural mechanization, people have continuously released various rice ear harvesters. In the currently used rice ear harvesters, the threshing system generally realizes the threshing of the rice ears by the rotation of the threshing cylinder, as patent ZL200620053117.7 discloses that a small rice harvester realizes threshing in this way, but due to Without the separation function, the husks and grass leaves will be mixed with the grains and collected together. The separation of grains, straws and leaves cannot be realized, which will affect the threshing efficiency. It is also possible to add a purification device after t...

In the currently used rice ear harvesters, the threshing system generally realizes the threshing of the rice ears by the rotation of the threshing cylinder, as patent ZL200620053117.7 discloses that a small rice harvester realizes threshing in this way, but due to Without the separation function, the husks and grass leaves will be mixed with the grains and collected together. The separation of grains, straws and leaves cannot be realized, which will affect the threshing efficiency. It is also possible to add a purification device after the threshing device to realize the separation of grains and straws. , the separation of leaves, such as a harvester disclosed in patent 200480001229.1 is to add a perforated vibrating plate and fan behind the thresher to separate the grain from the sundries, but this design adds a process, the structure is more complicated, and Separation is performed by combining the vibration of the vibrating plate with the fan, which has low efficiency and cannot completely remove the sundries from the grains
