Machine-harvested cotton cleaning process

Abstract

The invention discloses a machine-harvested cotton cleaning process. Machine-harvested cotton sequentially passes through a cotton feeding machine, a seed cotton pre-cleaning machine, a heavy impurity separator, a first unloader, a triangular drawing machine, a first-stage drying system, a first-stage boll cleaning negative pressure combined seed cotton cleaning unit, a second-stage drying system, a second-stage boll cleaning negative pressure combined seed cotton cleaning unit, a lower air suction seed cleaning machine, a cotton assorting auger, a cotton ginning machine, airflow skin cleaning machines, sawtooth skin cleaning machines, a cotton dust collecting auger and a packaging machine for processing. The machine-harvested cotton cleaning process has the technical effects that the key problems of the seed cotton cleaning process and the like are researched, a novel boll cleaning machine, a novel leaf cleaning machine and a combined cleaning machine of the boll cleaning machine and the leaf cleaning machine are provided in combination with the current machine-harvested cotton processing situation, the machine-harvested cotton processing flow is shortened, repeated damage of the machine to the length of seed cotton is avoided, the workload of manually cleaning an impurity discharging port of the machine is reduced, and more economic benefits can be brought to cotton enterprises.

Description

technical field [0001] The invention relates to the technical field of cotton processing, in particular to a machine-picked cotton cleaning process. Background technique [0002] my country's cotton planting density is very high, and the over-dense planting method has brought many difficulties to the cleaning of seed cotton. At present, most of the cotton in Xinjiang is harvested by machinery. Due to the dense planting, many cotton branches, cotton leaves, and boll shells cannot fall off, and are picked together with the seed cotton. Therefore, the seed cotton purchased by cotton processing enterprises can contain more than 20% impurities. Just aggravated the burden of seed cotton cleaning work. [0003] At present, the seed cotton pretreatment process of my country's cotton processing enterprises is long, which is mainly reflected in the diversification and complexity of seed cotton cleaning equipment; the pretreated seed cotton has poor consistency, high impurity content,...

Problems solved by technology

At present, most of the cotton in Xinjiang is harvested by machinery. Due to the dense planting, many cotton branches, cotton leaves, and boll shells cannot fall off, and are picked together with the seed cotton. Therefore, the seed cotton purchased by cotton processing enterprises can contain more than 20% impurities. Just aggravated the burden of seed cotton cleaning work

[0003] At present, the seed cotton pretreatment process of my country's cotton processing enterprises is long, which is mainly reflected in the diversification and complexity of seed cotton cleaning equipment; the pretreated seed cotton has poor consistency, high impurity content, and large cotton fiber damage, which seriously affects the final lint. The quality of the product; especially in the later stage of processing, the weather in Xinjiang is cold, the processing workers are cold and lazy, and the parts of the machine are blocked by impurities and no one cleans them, which is equivalent to invalid idling, and the effect of cleaning seed cotton cannot be achieved at all.
