Technical Field
[0001] The utility model belongs to the technical field of grain processing equipment, and particularly relates to a screening machine for agricultural product grain processing. Background Technique
[0002] When the existing grain screening machine screens grains, it uses gravity to separate rice grains. However, during grain processing, most rice grains are mixed with waste. It is difficult to separate rice grains from waste only by shaking, which reduces the quality of grain processing. The "a screening machine for grain processing" disclosed in the patent application number "CN201720826271.1" is also an increasingly mature technology. By the cooperation of a blower and a dust guide pipe, the processing environment is improved. And the secondary screening using the first screening plate and the second screening plate improves the screening efficiency. Through the cooperation of a waste box, a defective product box and a finished product box arranged at the bottom of the housing, the grain processing raw materials at different levels are separated and screened and collected. And the first filter screen and the second filter screen are used for another screening. Then, through the material guide pipe and the conduit, the screened rice grains are introduced into the finished product box, which improves the output of rice grains, reduces the cost of grain processing, and improves the practicability of the screening machine. However, this device still has the following defects: in actual use, large impurities such as straw in the rice grains will fall to the screening place along with the rice grains for screening, which is not convenient for extraction and removal. At the same time, impurities such as rice husks are relatively light in mass during screening, which is not convenient for removal, and a large amount of dust will be raised during shaking screening, and the dust cannot be effectively treated. Content of the Utility Model
[0003] The purpose of the utility model is to provide a screening machine for agricultural product grain processing, aiming at solving the problems in the prior art that large impurities such as straw in rice grains will fall to the screening place along with the rice grains for screening, which is not convenient for extraction and removal. At the same time, impurities such as rice husks are relatively light in mass during screening, which is not convenient for removal, and a large amount of dust will be raised during shaking screening, and the dust cannot be effectively treated.
[0004] To achieve the above purpose, the utility model provides the following technical scheme: It includes a box body, a vibration screening machine is arranged inside the box body, a feed pipe is arranged at the top of the box body, a feed funnel is arranged at the top of the feed pipe, a blowing blower is embedded on one side of the box body, a screening leakage net is arranged at the top of the vibration screening machine, a wind shield is arranged on one side at the top of the screening leakage net, discharge plates are arranged on both sides at the bottom of the screening leakage net, a first leakage pipe is arranged at the bottom on one side of the box body, a second leakage pipe is arranged at the bottom on the other side of the box body, and one ends of the first leakage pipe and the second leakage pipe are embedded on both sides at the bottom of the vibration screening machine.

[0012] In this scheme, the grains fall to the screening leakage net at the top of the vibration screening machine. Different-weight grains are separated by the vibration of the screening leakage net. The grains respectively fall into the first leakage pipe and the second leakage pipe through the discharge plate. By blowing air into the box body with a blowing fan, the grain dust on the surface of the screening leakage net is blown off. The windshield covers the dust, and the secondary exhaust fan sucks air to extract the dust during processing. The raised dust is filtered by the dust filter screen to purify the air.
