A picking spindle for a cotton picker with profiling hook teeth

Abstract

The invention provides a picking spindle for a cotton picker with profiling hook teeth, which comprises: a spindle picking rod, a bevel gear and hook teeth. Wherein, in order to avoid direct contact and abrasion between picking spindles and cotton stalks, the present invention also sets the outside of each tooth top of each hook tooth as a pre-grinding surface with profiling structure. In the present invention, the curvature is continuously and smoothly transitioned between the pre-grinding surface of the profiling structure and the outer wall of the conical hook tooth portion, and can be guided by the outer wall of the tapered hook tooth portion to limit the contact between the cutting edge of the hook tooth top and the cotton. direct contact between the rods. Therefore, the present invention can protect the coating layer of the cutting edge of the hook tooth, prevent it from falling off and being worn out, thereby effectively improving the service life of the picking spindle used for the cotton picker.

Description

technical field [0001] The invention relates to the technical field of cotton pickers, in particular to a picking spindle for a cotton picker with profiling hook teeth. Background technique [0002] The picking spindle is the key core component of the cotton picker, and its performance directly determines the performance of the cotton picker. The principle of picking cotton by the cotton picker is: hook teeth are pre-processed on the picking spindle. When the hook teeth touch the cotton, the tip of the hook teeth penetrates into the cotton, thereby hooking the cotton out of the cotton boll shell. Relying on its own rotation, the picking spindle can wind the cotton on its conical surface when the cotton is hooked out. After the picking spindle passes through the doffer disc, the cotton can be taken off by the doffer disc and collected to complete the cotton picking. [0003] At present, there are many types of ingots available on the market. According to the research, the ex...

AI Technical Summary

Problems solved by technology

In the process of continuous interaction with the cotton rod, the coating on the cutting edge of the hook teeth is prone to fall off or wear through, resulting in the exposure of the softer matrix inside the hook teeth

The base body of the hook teeth that loses the protection of the coating wears much faster during the working process, which eventually leads to the failure of the picking spindle

After the picking spindle wears out and fails, its cotton picking effect is greatly reduced, and a large amount of cotton cannot be picked smoothly, which will cause serious waste

Not only does this affect the quality of the cotton picker's work, but it also increases costs during the cotton harvesting process
