Problems solved by technology

Both structures have poor cleaning effect and are prone to clogging the vibrating screen
[0003] In addition, during the vibration cleaning process of the self-propelled harvester, especially the vibrating screen of the corn harvester, a large amount of impurities such as straw or dander will be brought into the sieve plate of the vibrating screen, which will seriously block the screen holes of the vibrating screen. Affect work efficiency

Abstract

The invention relates to a cleaning and sieving device of a maize harvester, the device comprising a rack, two fans, a sieving box and a lifting-type connecting rod mechanism connecting the frame to the sieving box. The lifting-type connecting rod mechanism is composed of a first and a second connecting rod mechanism arranged at the front and the rear of the sieving box respectively. The bottom of the rack is provided with an input shaft which is rotationally connected to the rack. The input shaft is provided with an eccentric block. A middle link rod sleeves the eccentric block. The other end of the middle link rod is rotationally connected to the first connecting rod mechanism. The fans are arranged on one side of the sieving box and fixedly connected to the rack. The cleaning and sieving device of a maize harvester has the advantages of favorable effect of cleaning and sieving and high efficiency and is not liable to. The invention also relates to a maize harvester comprising the cleaning and sieving device.

Description

technical field [0001] The invention relates to a cleaning machine, in particular to a cleaning device for a corn harvester and a corn harvester including the device. Background technique [0002] The vibrating screen of the self-propelled harvester mainly has two forms in the current market: one is that the two support points are all at the bottom, and the other is that the front support point is hoisted and the rear support point is at the bottom. Both structures have poor cleaning effect and are prone to clogging the vibrating screen. [0003] In addition, during the vibration cleaning process of the self-propelled harvester, especially the vibrating screen of the corn harvester, a large amount of impurities such as straw or dander will be brought into the sieve plate of the vibrating screen, which will seriously block the screen holes of the vibrating screen. affect work efficiency. Contents of the invention [0004] The invention provides a cleaning device for a cor...
