Description

A machine-picked cotton cotton opening and cleaning cylinder

technical field

The invention belongs to the technical field of cotton machinery and relates to a cotton opening and cleaning cylinder for machine-picked cotton.

Background technique

In recent years, the rapid increase in the cost of manual cotton picking due to rising labor prices has seriously restricted the competitiveness of Chinese cotton. According to relevant studies, mechanized cotton harvesting can improve picking efficiency, save the cost of cotton production, and improve the market competitiveness of cotton. In order to improve cotton picking efficiency and reduce cotton cost, it is imperative to use cotton pickers. Compared with hand-picked cotton, machine-picked cotton has a lower grade due to its shorter length, high short fiber content and more plant impurities. Only by improving the processing technology of machine-picked cotton can it be possible to solve the problem of cotton quality decline.

The process of the existing hand-picked cotton ginning process is as follows: the seed cotton passes through the heavy impurity separator, the external suction cotton separator, and the automatic control system of the seed cotton through the suction pipe, and then enters the drying tower and the internal suction cotton separator through the cotton conveying pipe. , inclined seed cotton cleaning machine, cotton gin, air-flow type skin cleaning machine, sawtooth type skin cleaning machine, and finally transported by the cotton conveying pipeline, then through the cotton collector, cotton slippery road, and finally packed into lint by the baler.

The disadvantage of the existing machine-picked cotton ginning process is that: at present, my country has begun to implement mechanical picking of cotton, and the existing hand-picked cotton ginning process is no longer suitable for processing machine cotton, and a new machine-picked cotton ginning process line needs to be replaced. The reconstruction of the factory building and the replacement of the production line of the machine-picked cotton ginning process not only increased the cost of the enterprise, but also caused waste of the original hand-picked cotton ginning process line; most impurities in the seed cotton were carried for too long in the entire process, resulting in Energy waste in the whole process; most of the impurities are removed in the second half of the whole process, and most of the impurities and dust are scattered on the process production line, making the processing workshop and machines covered with dust, etc., affecting the working environment and physical health of employees; The quality of removing impurities in the ginning process needs to be improved.

In the existing machine-picked cotton processing, the impact on the cotton is too large, causing serious damage to the cotton.

The present invention has the following beneficial effects:

1. Opening: Through the joint action of horn nails and the outer cylinder, the cotton is freely opened to loosen the cotton and facilitate sawtooth ginning;

2. Impurity removal: The cotton and impurities are separated by the beating action of the corner nails, and the impurities are discharged through the blowing and the lower sieve holes;

3. Compared with the traditional mechanism, the co-action of horn nails and the outer cylinder is used, and the cotton can be hit freely through the horn nails, which can greatly reduce the damage of machine-picked cotton, effectively reduce the short fiber content, and improve the quality of cotton.
