Picking head assembly of fully automatic cotton picker

Abstract

The invention discloses a picking head assembly of a fully automatic cotton picker, comprising a driving motor, a cylindrical picking head housing, a needle wheel barrel and a spring convey mechanism. A picking head in needle wheel barrel structure is adopted and passes through a gap in a free state of cotton plants horizontally to distribute the cotton flowers evenly within 360 degrees peripherally. 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 picked cotton is separated directly from impurities, for instance, cotton leaves, cotton stems and the like, thereby 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 high-level cotton picking ratio and the final picking ratio of 98% above; and the spring convey mechanism separates and conveys the cotton from the needle wheel barrel by utilizing the spiral convey theory. Cotton fiber is not destroyed to ensure the quality of the cotton; the invention has no special requirements for subsequent processing device and reduces the subsequent machining cost.

Description

technical field [0001] The invention relates to an accessory part of a cotton picking agricultural machine, in particular to a picking head assembly of 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.

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; Due to the structural characteristics of the cotton picking head of the machine, the cotton plant will be over-squeezed during the cotton picking process, so it is impossible to pick cotton at the green leaf stage, and it can only be picked after the cotton is fully opened and leaves are removed, and it must be equipped with an aircraft or Artificial spraying of chemical agents to promote early maturity of cotton, 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 more than 20%, or even more than 30%. The price is lower than that of hand-picked cotton, which causes greater economic losses to cotton farmers; the processing of this kind of cotton also requires 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 picking head structures of cotton pickers have appeared, but the disadvantages of over-squeezing the cotton plants during the picking process are common, which causes damage to the cotton plants and cannot be picked at the green leaf stage. Cotton can only be harvested at one time after the cotton is 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 flowers, so there are more impurities. Cotton grades cannot be separated, greatly reducing the economic value of cotton
