High-efficiency cotton harvesting device

Abstract

The invention relates to a high-efficiency cotton harvesting device, which is used for solving the problem that the cotton harvesting device is not suitable for picking in high stalk cotton fields. The technical proposal is that the high-efficiency cotton harvesting device comprises a cotton collection box and a fixed comb tooth, a rotating comb tooth mechanism and a conveying screw feeder which are positioned in the cotton collection box, wherein the rotating comb tooth mechanism consists of a rotating shaft and a rotating comb tooth, the teeth of the rotating comb tooth are evenly distributed along the rotating shaft axially, the comb tooth position of the rotating comb tooth corresponds to that of a fixed comb plate, and after improvement, the rotating comb tooth is a crescent bent hook-shaped tooth. The rotating comb tooth is designed as the hook-shaped comb tooth, thus in the rotating process, the front end of the rotating comb tooth combs off cotton gathered at the root of the fixed comb tooth from a cotton stalk so as to thoroughly separate the cotton from the cotton stalk. The high-efficiency cotton harvesting device is further provided with a comb mechanism additionally, and can continuously eliminate sundries filled in tooth gaps of the rotating comb tooth, so that the rotating comb tooth mechanism is maintained in a high-efficiency working condition.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a high-efficiency cotton harvester matched with a large cotton picker, and belongs to the technical field of agricultural harvesting machines. Background technique [0002] At present, in large cotton planting areas, the technology of harvesting cotton with mechanical equipment has been widely used. A type of large-scale cotton picker towed by a tractor, the harvester adopts a grate-toothed harvester, which is located at the front or side of the tractor, and separates the cotton bolls from the cotton stalks during the process of traveling with the tractor, and transports them to the The cleaning of impurities in the cotton cleaning box realizes the completion of cotton picking and cleaning at one time, and the work efficiency is high. The harvester is the core component of the cotton picker, and its structural design directly affects the harvesting efficiency. Chinese Patent No. 20081...

AI Technical Summary

Problems solved by technology

Tests have shown that the device has a better effect when used for harvesting low-stem cotton fields, but when it is used for harvesting high-stem cotton fields, it has the following problems: 1. Because the cotton stalks are too long, the cotton buds are not easy to grow from the cotton stalks. 2. The gap between the grate teeth of the rotating grate tooth mechanism is filled with debris such as cotton stalks and cotton leaves, which affects the cotton picking efficiency.
