Fully automatic cotton picker

Abstract

The invention discloses a fully automatic cotton picker, comprising a machine body as well as a cotton picking apparatus, an impurity separating apparatus and a clean cotton storage apparatus which are arranged on the machine body. A picking head in a needle wheel barrel structure is adopted and passes through a gap in a free state of cotton plants horizontally. The cotton plants during the cotton picking process are not over squeezed so that the cotton plants are not destroyed. During leafiness period, cotton leaves and flowers are not destroyed when cotton is picked. Therefore, the cotton can be picked for many times step by step and divided into classes; the cotton picked during picking is prevented from being polluted, and the impurity ratio of the cotton is reduced; the cotton picking head automatically rotates within 360 degrees, thereby ensuring the cotton picking ratio; cotton fiber during transportation is not destroyed to ensure quality of the cotton; the impurity separating apparatus separates the cotton due to density contrast of the cotton and impurities thoroughly and conveys the clean cotton by using a spiral rod, thereby improving quality of the clean cotton; the cost of cotton picking and the subsequent machining cost are reduced. The cotton picker is small in volume, light in weight and low in manufacturing cost.

Description

technical field [0001] The invention relates to an agricultural machinery for picking cotton, in particular to a fully automatic cotton picking machine. Background technique [0002] Cotton is an indispensable product for people's daily life, medical use and industry. Cotton planting generally adopts the form of large-scale sowing. Due to its production characteristics, it is necessary to pick mature cotton flowers from the cotton plant and enter the subsequent processing procedure after harvesting. Because picking cotton needs to go through the process of identification and picking, it is a relatively complicated work. Therefore, in the prior art, cotton picking has become a common operation method by manual operation. Although manual picking can guarantee the picking effect, the labor efficiency is low, a large amount of labor is wasted, and it cannot meet the operation requirements when rush harvesting is required. [0003] In order to solve the above problems, a cotton...

AI Technical Summary

Problems solved by technology

Due to the diversity of cotton planting patterns and differences in climate and environment, imported cotton pickers have the disadvantages of high requirements for the working environment and high prices during use; During the cotton picking process, the machine will over-squeeze the cotton plants, so it is impossible to pick cotton in the green leaf stage. It can only be picked after the cotton is fully opened and leaves are removed. It must be equipped with an aircraft or artificially sprayed with chemicals to urge the cotton to grow. Cotton is premature, otherwise it cannot be picked, the process is complicated, and the cost is wasted; the picked cotton cannot be graded, contains a lot of impurities, and the impurity rate is above 20%, or even more than 30%. It will cause great economic loss to the cotton farmers; the processing of this kind of cotton also needs special imported ginning equipment, which increases the processing cost of cotton

At the same time, the net picking rate of imported cotton pickers is about 90%, which is relatively low, and the cotton that has been rolled and cleaned by special equipment has relatively increased fiber damage, reduced cotton whiteness, and reduced cotton quality. market competitiveness

[0004] In order to solve the above problems of imported cotton pickers, a variety of cotton picker structures have appeared, but the disadvantages of over-squeezing the cotton plants during the picking process are common, causing damage to the cotton plants, and it is impossible to pick cotton in the green leaf stage. The cotton can only be harvested at one time after the leaves are completely opened and defoliated; after extrusion, the cone needle is inserted into the cotton plant to mix the dry cotton leaves and stems of the cotton plant into the cotton flower, so there are many impurities and cannot be separated Cotton grades, greatly reducing the economic value of cotton
