AI Technical Summary
When the feed amount of existing harvesters is reduced, the contact between the threshing drum and the crop is reduced, resulting in unstable threshing force, making it difficult for some grains to detach and causing missed threshing.
The device uses a toothed wheel axle in conjunction with a shredder. The shredder's shredder plate is curved and equipped with an elastic plate. The elastic plate deforms when the feed amount changes to ensure that the shredder plate always contacts the crop. The threshing efficiency is improved by using the toothed wheel axle in conjunction with the shredder.
When the feed amount changes, the elastic plate adapts to the deformation, ensuring that the threshing board always contacts the crop, reducing missed threshing, and improving threshing quality and operational reliability.
