A crushing, dust-removing and cleaning device for an online grain moisture meter

Abstract

The invention discloses a crushing and dust-removing cleaning device for an online grain moisture meter, comprising a crushing box and a cleaning box, the crushing box and the cleaning box are fixedly connected, and a resistive moisture analyzer is fixedly installed on the cleaning box. A liquid crystal display is installed on the side of the resistive moisture analyzer far away from the cleaning box, the crushing box is fixedly installed on the hoist, a squeeze roller is installed in the detection chamber, and a squeeze roller cleaning cover is installed on the squeeze roller The end of the extrusion roller away from the detection chamber is located in the air-drying pipe, the air-drying pipe is connected to the cyclone cleaning ring, and the end of the air-drying pipe away from the cyclone cleaning ring is connected to the blower. The effective separation of dust can air-dry the fruit pulp on the measuring roller to prevent the accumulation of fruit pulp and cause the loss measurement value to be too large. At the same time, it can also pre-break the grain, effectively ensuring the normal use of the measuring roller and improving the measurement the accuracy.

Description

technical field [0001] The invention relates to the technical field of agricultural devices, in particular to a crushing and dust removal cleaning device for an online grain moisture meter. Background technique [0002] With the improvement of living standards and material needs, people’s demand for high-quality grains is gradually increasing. The production of high-quality grains requires not only good varieties and growth environments, but also scientific drying and storage methods to ensure the quality of rice. According to foreign According to experience, high-moisture grains should be dried in the machine within 3 hours after harvesting, and the moisture content should be reduced to the safe storage standard within 24 hours to ensure that the biological activity and quality of the grains will not be affected. Compared with traditional grain drying methods (ground drying) The grain impurities increase, the quality is reduced, the processing capacity is limited, and it is...

AI Technical Summary

Problems solved by technology

[0004] Although the problem that straw doping affects the accuracy of measurement is solved, there are still obvious defects in the use of the above-mentioned online grain moisture meter feeding and impurity removal device: 1. The above-mentioned device can only clean up straw, awns, etc. , cannot remove fine particles such as dust, because the conductors mixed in the dust will affect the resistance value, thereby affecting the measurement results; 2. The brush used in the above device can only clean the particles on the roller, and cannot remove the particles attached The fruit pulp of the above grains, the accumulated pulp may cause the measured moisture value to be too large, and at the same time, the squeezed pulp adheres to the surface of the rolling roller and will cause damage to the rolling roller; 3. The above-mentioned device uses the rolling roller Carry out a rolling on the grain, and then get the measurement results, because the particle size of different grains varies greatly, and some grains have a thick coating, long-term rolling may cause damage to the roller, and the coating will be damaged. Block the electrode connection at both ends of the roller, thereby affecting the measurement results
