Vibrating screen wind deflector structure for harvester

Abstract

The invention discloses a vibrating sieve deflector structure used on a harvester, which comprises a vibrating sieve and a deflector. The vibrating sieve is installed on a cleaning device of the harvester. The bottom is matched with the installation of the grain collection bin; the vibrating screen is evenly equipped with several sieve holes. The air bottom plate and the two wedge-shaped air-guiding side plates jointly form the air-guiding wedge-shaped chamber, and all the screen holes of the vibrating screen are connected with the air-guiding wedge-shaped chamber. The air outlet pipe of the fan communicates with the air guide wedge-shaped cavity of the air guide plate, and several slits are opened on the air guide base plate. The wind blown by the fan of the present invention is guided to the lower side of the vibrating screen by the air deflector, and the impurities are blown away so that the grains fall into the grain collection bin through the screen holes and gaps of the vibrating screen, and the wind blown by the fan is guided to the vibrating screen. The lower side improves the air guide effect and thus improves the cleaning efficiency.

Description

technical field [0001] The invention relates to the technical field of harvesters, in particular to a vibrating screen wind deflector structure used on harvesters. Background technique [0002] In order to separate the grain from the impurities, it is generally required that the wind blown by the fan is blown upward at an angle. At present, most of the air guide structures on the market are air guide plates installed at the air outlet of the fan. Although this structure can achieve the effect of air guide, it cannot guide all the wind blown by the fan to the lower side of the vibrating screen. , so the wind guiding effect is not very good. So far, there is no vibrating screen wind deflector structure that can guide the wind blown by the fan to the lower side of the vibrating screen. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a vibrating screen air deflector structure capable of guiding...
