Dust reducing device of self-propelled peanut picking combine harvester

Abstract

The invention discloses a dust reducing device of a self-propelled peanut picking combine harvester. The device comprises a seedling collecting box and a cyclone separation device. The cyclone separation device comprises an outer cylinder and an inner cylinder; and a spiral flow guide plate is arranged on the outer side of the inner cylinder. Airflow carrying dust and crushed seedlings is spirallydistributed between the outer cylinder and the inner cylinder, so that the dust is discharged into the seedling collecting box from a crushed seedling outlet in the bottom of the outer cylinder underthe action of centrifugal force. A plurality of inertia dust removal spiral baffles which are spirally distributed are arranged in the inner barrel, residual dust and crushed seedlings in the airflowentering the inner cylinder collide with the inertia dust removal spiral baffles, the dust and the crushed seedlings gradually fall down after the speed is reduced, and therefore separation of the dust and the crushed seedlings is achieved. According to the device, a mode of combining cyclone dust removal and inertia dust removal is adopted, the crushed seedlings and the dust carried in the airflow are separated, dust discharged by the self-propelled peanut picking combine harvester can be reduced, and the dust removal mode does not need filtering equipment, and is low in resistance, good indust removal effect and low in cost.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a self-propelled peanut picking combine harvester dust suppression device. Background technique [0002] With the rapid development of large-scale agricultural production, the development of agricultural mechanization occupies an important position. Including the mechanization of agricultural planting, harvesting, green manure and post-production processing, as well as the mechanized breeding of agricultural livestock and other fields. While these agricultural productions are developing rapidly, the dust pollution generated in the agricultural production environment is also increasing day by day. [0003] By the end of 2018, China's peanut planting, sowing, and harvesting mechanization levels had reached 75.56%, 50.04%, and 39.72%. With the adjustment of my country's planting industry structure, the peanut planting area has increased significantly and the development of la...

AI Technical Summary

Problems solved by technology

[0007] 2. The original mechanized harvesting of peanuts did not consider and design a dust suppression mechanism or reduce the spread of dust through the direction of the exhaust port of the seedling collection box

[0009] 4. The original peanut mechanized harvester was rebuilt on the problem of dust reduction, the structure was complex, and the cost was high, which increased the cost of the peanut mechanized harvester

[0010] 5. Some existing peanut mechanized harvesters use filtration to remove dust particles, but a large amount of dust with different particle sizes will be generated during the harvesting process. Large particles of dust will quickly block the filter material and increase the filter resistance of the filter material. And reduce the filtering effect; this makes the filter material need to be replaced frequently, increases the use cost and working hours, and reduces the operating efficiency
