Abstract

The invention relates to an air suction gravity sieve and air blowing gravity sieve combined type grain classificatory. An air suction gravity sieve is arranged on the upper back portion of a rack, and an air blowing gravity sieve is arranged on the lower front portion of the rack. The front portion of the air suction gravity sieve and the back portion of the air blowing gravity sieve are overlapped in the front-back direction. An air suction gravity platform supporting arm is rotationally connected to an air suction gravity platform. An air blowing gravity platform supporting arm is rotationally connected to an air blowing gravity platform. One end of an air suction gravity platform driving rod is fixedly connected to an air suction gravity platform eccentric bearing outer sleeve, and the other end of the air suction gravity platform driving rod is movably connected to the air suction gravity platform. One end of an air blowing gravity platform driving rod is fixedly connected to an air blowing gravity platform eccentric bearing outer sleeve, and the other end of the air blowing gravity platform driving rod is movably connected to the air blowing gravity platform. A driving shaft is connected to an air suction gravity platform eccentric bearing inner ring and an air blowing gravity platform eccentric bearing inner ring in a sleeved mode. The air suction gravity platform and the air blowing gravity platform are driven by the driving shaft and move in the opposite directions in the same back-and-forth movement period. The air suction gravity sieve and air blowing gravity sieve combined type grain classificatory of the structure has the advantages of being high in impurity removing efficiency and precision, stable in working process, environmentally friendly and the like.

Description

technical field [0001] The invention relates to an agricultural grain cleaning and beneficiation machine, in particular to a combined grain beneficiation machine of a suction gravitational sieve and a blowing gravitational sieve. Background technique [0002] For modern agriculture, the extensive and extensive application of harvesting machinery has accelerated the industrialized production of agriculture. In the process of harvesting seeds and grains by agricultural machinery, due to the influence of region, climate and variety, the seeds and grains will be harvested. Numerous debris such as weed seeds, pebbles, broken straw, degraded, immature, disease-damaged and moldy seeds and grains are present. Some cleaning machines that appear in the prior art can have a certain cleaning effect on the above problems, but the cleaning efficiency and accuracy are still not good enough, and they cannot remove and separate different types of debris well. At the same time, these mechanic...
