Self-cleaning type threshing and cleaning equipment

Abstract

The invention discloses self-cleaning type threshing and cleaning equipment, and relates to the technical field of automatic threshing and cleaning equipment. The equipment comprises a rack, a feeding conveying belt, a straw conveying belt, a threshing mechanism, and a cleaning mechanism. By arranging the threshing mechanism and the cleaning mechanism in the rack, rapeseeds on a threshing table are automatically separated from shells and straws of the rapeseeds; by controlling start and stop positions of a first motor, the lifting height of a roller is adjusted, so that the equipment can adapt to rapeseed products of various specifications, and the universality of the rapeseed threshing and cleaning equipment is improved; the threshing table is pushed upwards through the output end of an electric push rod, a push plate rake is driven to slide on the threshing table in a vibration mode, and scattered rapeseeds located in shells and straws are further shaken off and separated from the shells and straws and fall onto a push-pull type sieve plate, so that the impact of traditional wind screening on a cleaning environment in the prior art is avoided.

Description

technical field [0001] The invention relates to the technical field of automatic threshing and cleaning equipment, in particular to a self-cleaning type threshing and cleaning equipment. Background technique [0002] After the rapeseed is mature, it needs to be threshed and screened. When the harvested rapeseed is threshed and cleaned, the rapeseed in the threshing tray is often rubbed directly by the roller, and then the strong wind is poured into it through the air supply equipment. Exclude and clean shell straw. [0003] However, in the long-term application process of the prior art, it is found that there are still certain disadvantages: 1. The threshing process is aimed at different specifications and different types of rapeseed, and it is necessary to replace the corresponding type of drum, which is troublesome and poor in versatility. ; 2. Kneading and threshing can easily cause partial fragmentation of the grains, and the roots of the broken grains are attached to t...

[0003] However, in the long-term application process of the prior art, it is found that there are still certain disadvantages: 1. The threshing process is aimed at different specifications and different types of rapeseed, and it is necessary to replace the corresponding type of drum, which is troublesome and poor in versatility. ; 2. Kneading and threshing can easily cause partial fragmentation of the grains, and the roots of the broken grains are attached to the shell and finally removed with the wind, resulting in the waste of incomplete threshing, and the traditional wind screening method makes the screening and cleaning process more difficult. The dust is relatively large, which will have adverse effects on the cleaning environment and the appearance of the grains after cleaning
