Problems solved by technology

Traditional threshing drums are all rigid, and the shelling, crushing and internal cracks of the peeled fruit particles seriously affect the seed germination rate.
In addition, the strong vibration and loud noise generated by traditional threshers not only affect the life of the thresher, but also cause great pollution to the environment, and do not meet the current requirements of green agricultural production.

Embodiment Construction

[0009] refer to figure 1 , figure 2 As shown, the main structure of the thresher includes: the ear of corn is fed from the feeding port (4), the ear of corn rotates with the helical teeth (1) on the drum, and is subjected to polyurethane during the forward movement along the axial direction. The brushing of the flexible rod teeth (3) and the extrusion of the tapered drum shell (2) achieve threshing under the action of friction. The threshed corn fruit is collected by the collecting hopper (6), and the corn cob is finally discharged from the core discharge port (8) at the rear end of the thresher.

[0010] This new design is based on threshing dynamics, and simplifies the threshing process to the impact of grains with mass M at the initial velocity V0, which can be simplified as the tooth end of the threshing tooth of the elastic cantilever beam, so the threshing tooth fixed on the drum can be flexibly Rod teeth (3) are equivalently regarded as cantilever beams deformed by t...

Abstract

The invention relates to agricultural machinery and particularly relates to a threshing machine applicable to threshing of cereals including corns and the like. The threshing machine is mainly composed of spiral plate teeth (1), a tapered roller shell (2), flexible rod teeth (3) and the like. On the basis of analyzing and researching a corn threshing ability, the invention designs a flexible rod tooth threshing roller with a threshing principle which is similar with rigid rod tooth threshing; the result of a threshing contrast test shows that the un-threshing rate and the threshing rate in flexible rod tooth threshing indexes are similar with those of a rigid rod tooth threshing roller; and the crushing rate and the trash content are remarkably lower than those of the rigid rod tooth threshing roller, so that the cereals are effectively prevented from damages caused by rigid impacts in a threshing process.

Description

technical field [0001] The invention relates to the field of agricultural machinery, specifically a thresher. Background technique [0002] Threshing is a crucial part of corn harvesting, and the core of the threshing system is the threshing drum. There are many types of traditional threshing cylinders, which can be summed up as nail-toothed, grained rod and bow-toothed, etc., mainly relying on the principles of impact, brushing, squeezing and rubbing to achieve ear threshing. Traditional threshing drums are all rigid, and the shelling, crushing and internal cracks of the peeled fruit particles seriously affect the germination rate of seeds. In addition, the strong vibration and loud noise generated by traditional threshers not only affect the life of the whole thresher, but also cause great pollution to the environment, and do not meet the requirements of current green agricultural production. Contents of the invention [0003] In order to overcome the deficiencies of t...
