Technical Field

The utility model relates to the technical field of cotton processing, in particular to a seed cotton impurity removal feeding structure of a cotton picking and testing mill.

Background

The cotton clothing fraction refers to the weight ratio of ginned cotton to unginned cotton obtained by processing a certain amount of unginned cotton, which is a primary index for measuring the price of unginned cotton, namely, unginned cotton is weighed before being processed, and then is put into a test rolling mill for impurity removal and separation, and ginned cotton is weighed after impurity removal, so that the ginned cotton content in the whole batch of unginned cotton can be known.

At present, the existing test rolling machine in China mainly comprises a saw tooth type cotton seed separating mechanism, so that problems exist, firstly, due to the fact that a seed cotton impurity cleaning mechanism (more bell shells, leaves, broken branches and the like) is lacked, machine-picked cotton with more impurities cannot be cleaned, impurities in seed cotton cannot be removed, the impurity content of ginned cotton is large, and the effect of 'test' cannot be achieved.

In the utility model patent of publication No. CN215628428U, a novel integrated machine cotton picking and testing mill is disclosed, when cotton passes through a feed hopper, the cotton is torn off through a cotton opening roller, then the torn cotton and cotton seeds fall into the cotton picking and testing mill main body downwards, cotton threads falling into the cotton picking and testing mill main body are rotationally transmitted to a cotton winding roller from the cotton winding roller, then are discharged from a discharge hole along a corresponding bottom surface of a guide plate downwards from the cotton winding roller, the cotton seeds vertically fall onto an inclined surface of a guide box downwards in the feed hopper, the cotton threads are blocked by a filter screen, the cotton seeds are dragged into the guide box through a filter hole on the filter screen along a cotton screening hole, fall into a cotton seed collecting cabinet to be collected, and the collected cotton seeds can be rapidly and intensively processed by pulling a handle outwards.

The patent does not have a special cleaning structure for impurities (bell shells, leaves, broken branches and the like) contained in the mechanically-picked cotton, and therefore, a seed cotton impurity removal and feeding structure of a cotton picking test rolling mill is provided.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1, the seed cotton impurity removal and feeding structure of the cotton picking and testing mill comprises a shell 21, wherein a baffle 22 arranged according to a cotton motion track is arranged in the shell, one end of the shell is provided with an impurity removal inlet, a cotton inlet cotton feeding roller 4 is arranged at the impurity removal inlet, an upper layer rack roller 5 and an upper layer brush roller 6 which are arranged along the baffle are arranged at the rear end of the impurity removal inlet, and the rotation directions of the upper layer rack roller 5 and the upper layer brush roller 6 are opposite; the rear end of upper brush roller 6 is provided with a plurality of groups of clear flowers spike roller 7 that set up along the baffle, clear flowers spike roller 7 below is provided with arranges miscellaneous net 19, it is provided with the miscellaneous mouth 20 to arrange miscellaneous net below. The impurity removing net 19 is also arranged below the upper rack roller 5, and the impurity extracting port 20 is arranged below the impurity removing net.

The specific blowing spike rollers are two groups, each group of 3 blowing spike rollers, and a trash discharging net is arranged below each blowing spike roller. Wherein, impurity channels 8 are arranged between the two groups of the cleaning spike rollers, and a large number of gaps (between 5mm and 20 mm) are arranged on the impurity discharging net.

The working process of the utility model comprises the following steps: firstly, the cotton picked by the machine is sent into a trash inlet through a conveyor 2, the cotton picked by the machine is conveyed to a cleaning part through the rotation of a cotton feeding roller 4 at a cotton inlet, seed cotton in the cotton picked by the machine is hooked and temporarily fixed on the surface by means of the high-speed rotation of a rack roller 5 at the upper layer and saw teeth arranged on the surface of the rack roller, and the trash such as bell shells, leaves, broken branches and the like can be thrown away due to centrifugal force and fall to the corresponding trash extraction opening position. The upper layer brush roller 6 and the upper layer rack roller 5 are matched to act, and the rotation directions of the upper layer brush roller and the upper layer rack roller are opposite. A large number of bristles are densely distributed on the surface of the upper layer brush roller, air flow can be generated in the high-speed rotation process, and seed cotton is separated and enters the subsequent working procedure under the combined action of the air flow and the bristles. The process is matched with the two modes of blowing of air flow and brushing of the brush hair, so that the integrity of cotton fibers can be protected to the greatest extent. Through the step, impurities such as bell shells, fallen leaves and the like in the machine-picked cotton can be effectively removed, the processed machine-picked cotton reaches the clean degree of manual picking, and after the cotton moves to a certain position, the cotton is continuously hit by the cleaning spike roller 7 and is driven to continuously move forwards until the cotton passes through each cleaning spike roller 7. The cotton is loosened, twisted, rolled and collided between the cotton and the spike roller during the high-speed beating process so as to promote the impurity mixed in the cotton fiber to separate. A trash discharging net 19 is arranged below each cleaning spike roller, and has two functions: firstly, a working surface is provided for the cleaning nail-pricking roller, so that the striking effect is enhanced; secondly, the cotton can move along the rotation direction of the blowing spike roller. There are a large number of gaps on the impurity removing net, and impurities can fall into the impurity extracting port 20 below through the gaps during the striking process.
