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 device for a corn harvester, which includes a frame, a fan, a screen box, and a hoisting linkage mechanism for connecting the frame and the screen box; the linkage mechanism includes a And the first link mechanism and the second link mechanism at the rear; the bottom of the frame is provided with an input shaft rotationally connected with it; the input shaft is provided with an eccentric block; the eccentric block is covered with a middle link ; The other end of the middle link is rotatably connected to the first linkage mechanism; the fan is located on one side of the screen box and is fixedly connected to the frame. The invention has good cleaning effect, high efficiency and is not easy to block. The invention also relates to a corn harvester comprising the above 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...
