Abstract
The utility model relates to a wind separation vibrating screen thresher which comprises a machine frame, wherein the upper part of the machine frame is provided with a threshing roller, the lower part of the threshing roller is provided with a vibrating screen, a fan is arranged between the upper part of the inner end of the vibrating screen and the machine frame, the outer end of the vibrating screen is communicated with a trash hole of one side of the machine frame, the lower part of the vibrating screen is provided with a collection hopper, one side of the collection hopper is provided with a discharge channel, and the discharge channel is communicated with the discharge hole of the machine frame. For the utility model, the fan and the vibrating screen are arranged in the thresher, and the thresher simultaneously implements the working procedures of wind separation and screening separation in the threshing process in order to result in that straw, empty grain shell, wheat stalk or other sundries are separated. The utility model can effectively improve the screening separation quality of materials, reduce the labor intensity of workers, increase the work efficiency, and save time and trouble. The utility model has the advantages of the reasonable structure, the easy operation, the small volume and the light weight, and is applied to the threshing processing of rice, wheat, broomcorn and other materials when harvested.
Description
[technical field]
The utility model relates to a kind of farm machinery, relates in particular to a kind of selection by winnowing and selection by winnowing vibratory sieve thresher that screens material of carrying out in threshing course.
[background technology]
At present; vast rural area is when materials such as harvesting paddy rice, wheat and Chinese sorghum; the thresher that adopts all is the thresher of simple function; also have foreign material such as a large amount of straw, empty material shell or straw in the material after the threshing; also need carry out one screening process after the threshing, this operation is a job that takes time and effort very much.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of selection by winnowing vibratory sieve thresher of setting up blower fan and vibratory sieve in thresher, just can carry out selection by winnowing and screening simultaneously to material in threshing.
The technical method that its technical problem that solves the utility model adopts is: a kind of selection by winnowing vibratory sieve thresher; comprise frame; described upper rack is installed grain threshing roller; vibratory sieve is equipped with in bottom at grain threshing roller; between inner top of described vibratory sieve and frame blower fan is housed, the outer end of this vibratory sieve communicates with frame one side impurity discharging port, in the bottom of vibratory sieve aggregate bin is housed; one side at this aggregate bin is provided with blow tank, and this blow tank communicates with the frame discharging opening.
Described vibratory sieve both sides are provided with rocking arm, and this rocking arm links by connecting rod and eccentric wheel.
On each of described grain threshing roller, blower fan, the same end of eccentric wheel belt pulley is housed.
The belt pulley of described grain threshing roller divides big belt pulley and small belt pulley, and big small belt pulley is contained on the same axle.
The big belt pulley of described grain threshing roller and blower fan belt pulley link by belt and power source belt pulley.
The small belt pulley of described grain threshing roller links by the belt pulley of belt and camshaft.
The beneficial effects of the utility model are: blower fan and vibratory sieve are installed in thresher, and thresher carries out the operation of selection by winnowing and screening simultaneously in threshing course, makes and is separated by foreign material such as the straw in the threshing material, empty material shell or straws.Can effectively improve material screening quality, alleviate working strength of workers, improve operating efficiency, not only save time but also save trouble.Have rational in infrastructure, simple to operate, volume is few and the advantage of weight, the processing of threshing when being applicable to the harvesting of materials such as paddy rice, wheat and Chinese sorghum.
