Breaking-dedusting-clearing device for online grain-moisture measuring instrument

Abstract

The invention discloses a breaking-dedusting-clearing device for an online grain-moisture measuring instrument. The breaking-dedusting-clearing device comprises a breaking box and a clearing box, wherein the breaking box is fixedly connected with the clearing box; a resistance-type moisture analyzer is fixedly arranged on the clearing box; one side of the resistance-type moisture analyzer, separated from the clearing box, is provided with a liquid-crystal display screen; the breaking box is fixedly arranged on a lifter; an extruding roll is arranged in a detecting chamber and is provided withan extruding-roll clearing cover; one end of the extruding roll, separated from the detecting chamber, is positioned in an air drying pipe; the air drying pipe is communicated with a cyclone clearingring; one end of the air drying pipe, separated from the cyclone clearing ring, is communicated with an air blower. The breaking-dedusting-clearing device disclosed by the invention has the beneficialeffects that straws and dust mixed in grains can be effectively separated by the air blower, and fruit pulp on a measuring roll can be air-dried, so that slightly-high moisture measuring value causedby accumulation of the fruit pulp can be prevented; simultaneously, the grains also can be pre-broken, so that the normal use of the measuring roll is effectively guaranteed and the accuracy of measurement is improved simultaneously.

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
