Combined comb-tooth-type cotton picker with self-cleaning function

Abstract

The invention discloses a combined comb-tooth-type cotton picker with a self-cleaning function, comprising a power-driven chain-harrow-type transmission device arranged on the upper frontal end of a rack and a cotton cleaning machine formed by a U-shaped sawtooth roller and a steel brush cotton roller; a cotton stalk pressing guide device is arranged on the rack at the front part of a picking platform; comb teeth which are mutually parallel are fixedly connected on a crossbeam evenly; the front ends of the comb teeth incline upwards; a power-driven pulling preventing roller is arranged at the rear lower part of the comb teeth; the chain-harrow-type transmission device which is matched with the comb teeth is arranged above the comb teeth; a cotton feeding roller is arranged on a discharge hole of the chain-harrow-type transmission device; the cotton cleaning device formed by the U-shaped sawtooth roller and the steel brush cotton roller is arranged below the cotton feeding roller; and a cotton collecting chamber is arranged at the rear part of the cleaning device. The cotton picker provided by the invention has no special requirements on the cotton planting mode in row space, and can be suitable for the planting mode of any row space; in the combined cotton picker, 'zero distance' transmission is implemented, thus the cotton picker has the advantages of novel and compact structure, simple and direct operational procedures, convenience in maintenance, low manufacture cost, long service life, low operational failure rate and low-impurity seed cotton and the like.

Description

technical field [0001] The invention belongs to cotton harvesting machinery, in particular to a combined comb-teeth cotton picking device with self-cleaning function. Background technique [0002] Xinjiang is an important cotton planting base in my country. At present, the cotton planting area in Xinjiang is about 22.5 million mu. Conventional manual cotton picking has low production efficiency, long harvest period, heavy labor, difficult conditions, and high labor intensity. Every cotton picking season, not only government officials, employees, and students are mobilized to participate in the harvest, but they also have to be hired from outside the province every year. Millions of laborers help pick cotton. Despite this, a large number of later flowers are lost due to lack of labor for harvesting. In addition, the labor force from other provinces participated in the cotton harvesting work, which brought many problems to transportation, accommodation, and social security....

AI Technical Summary

Problems solved by technology

During the picking process of the comb-toothed cotton picker, it is generally easy to pick cotton leaves, cotton short fruit branches, cotton shells, etc. together. When the cotton and cotton leaves are transported from the cotton picking head to the pre-cleaning device, due to the external force The multiple blows and rubbing actions make the cotton leaves more fragile and mixed with the cotton, which is very difficult to clean up and greatly affects the quality of the cotton. cleaning effort, which not only degrades the cotton, but also increases the cost of operations such as cotton processing

[0004] In addition, there are also those that install the cleaning device on the cotton picker, such as ZL 200620008594.1, ZL 200710180035.8, and ZL 200820103447.1. These patents are all in the separate configuration of the picking head and the cleaning device, but this makes the structure of the whole machine more complicated, and the overall The volume of the machine is also relatively large, and the cost of the machine tool is relatively high
