Embodiment Construction

[0025] In the following, the present invention will be further detailed in combination with examples and drawings:

[0026] Such as figure 1 , figure 2 , image 3 As shown, the adaptive adjusting device for the size of the threshing roller cavity of the corn thresher of the present invention is mainly composed of the front side plate 1, the rear side plate 6, the threshing roller 3, the threshing tube 5, the vertical shaft 11, and the front side rotating hinge of the threshing tube 4. The rear side of the threshing tube is composed of a tension spring 9, a bearing before the threshing roller rotates, a bearing 7, a tension spring fixing rod 8 and a tension spring connecting rod 12 after the threshing roller rotates.

[0027] The threshing roller 3 is fixed on the front side plate 1 and the rear side plate 6 through the front bearing 2 and the rear side plate 6 after the threshing roller rotates. The threshing roller 3 can be driven by the outside under the support of the front sid...

Abstract

The invention discloses an adaptive controlling device for the size of a threshing roller cavity of a corn threshing machine. The adaptive controlling device mainly comprises a front side plate, a rear side plate, a threshing roller, a threshing tube, a threshing tube front rotating hinge, a threshing tube rear tension spring and a tension spring fixing rod, wherein the threshing roller is fixed between the front side plate and the rear side plate and only can perform principal rotating motion; and the front end of the threshing tube is fixedly connected with the front side plate through the threshing tube front rotating hinge, so that the threshing tube only can rotate around the hinge, and the rear side of the threshing tube moves away from the threshing roller or moves towards the threshing roller. The rear side of the threshing tube is close to the threshing roller under the effect of a downward pretension force of the threshing tube rear tension spring, and stays on the lower side of a large through hole reserved in the rear side plate when the threshing tube is in a normal state. When the adaptive controlling device works, a cob can upward jack the threshing tube so that the threshing tube rotates around the hinge; and a gap between the rear side of the threshing tube and the threshing roller is controlled adaptively. By the adaptive controlling device for the size of the threshing roller cavity of the corn threshing machine, the size of an inlet of the threshing machine is unchanged, and requirements of adaptive high-efficiency threshing of the corn threshing machine on cobs with different sizes are met.

Description

Technical field [0001] The invention belongs to the technical field of food processing engineering. Specifically, it refers to an adaptive adjustment device for the size of the threshing roll cavity of a corn thresher. Background technique [0002] The corn thresher is a mechanical device that can automatically separate the corn kernels and cobs in the corn cob. When the corn thresher is working, the corn cobs are fed from the feed port. The corn cobs are impacted in the cavity formed by the high-speed rotating threshing roller and the threshing tube to separate the corn kernels from the corn cobs, and the grains are separated and discharged through the grain collecting device. The corn cob is discharged from the tail of the machine to realize the corn threshing operation. The threshing roller cavity formed by the threshing roller and the threshing tube in the corn thresher is the key part of the corn cob to separate the corn kernel and the corn cob, which directly affects the ...
