a cotton cleaning machine

Abstract

The invention relates to a cotton cleaning machine. A set of thorn rollers arranged in parallel are arranged on the frame near the feeding port in the upper chamber, and a separation net bottom is arranged below the thorn rollers. There are upper rack rollers, lower rack rollers, cotton brushing rollers, miscellaneous auger, cotton discharge channel and cotton discharge auger indoors; a negative pressure chamber is arranged in the casing on the other side below the upper chamber, The upper chamber is connected with the upper end of the negative pressure chamber through the bottom of the separation net, the lower end of the negative pressure chamber is connected with the suction end of the fan through the suction box, and the inlet of the three-way elbow is connected with the blowing end of the fan. The upper outlet of the pipe is connected with one end of the flat air pipe, the other end of the flat air pipe is connected with the lower inlet of the blowing pipe, and the discharge port is connected with the upper inlet of the blowing pipe. The invention has reasonable structure design, convenient use, good cotton cleaning effect, and can send the cleaned seed cotton into the cotton storage box without additional fan.

Description

technical field [0001] The invention relates to a cleaning machine. Background technique [0002] Before cotton processing, the impurities in the seed cotton must be cleaned first, and the cotton cleaning machine is a device used to remove impurities in the seed cotton. In the past, cotton was mainly picked by hand. When picking, the quality of cotton was high, and the impurity rate of seed cotton was low, and the impurities were mainly cotton leaves, dust and other fine impurities. Cotton accounts for an increasing proportion of seed cotton, and machine-picked cotton inevitably contains a large amount of impurities, which include not only fine impurities such as cotton leaves and dust, but also large impurities such as cotton stalks, cotton boll shells, and ropes. They are all fibrous, entangled with cotton fibers and difficult to separate. Although the existing cleaning machine has a certain cleaning effect, it has the following disadvantages: one, the existing cleaning ...

In the past, cotton was mainly picked by hand. When picking, the quality of cotton was high, and the impurity rate of seed cotton was low, and the impurities were mainly cotton leaves, dust and other fine impurities. Cotton accounts for an increasing proportion of seed cotton, and machine-picked cotton inevitably contains a large amount of impurities, which include not only fine impurities such as cotton leaves and dust, but also large impurities such as cotton stalks, cotton boll shells, and ropes. All are fibrous, entangled with cotton fibers and difficult to separate

Although the existing cleaning machine has a certain cleaning effect, it has the following disadvantages: one, the existing cleaning machine utilizes the blowing effect of the blower fan, and the positive pressure of the two-phase flow of seed cotton and air enters the cotton cleaning machine, and the seed cotton Under the blowing of the positive air flow, it cannot be evenly distributed on the work rolls, so it is difficult to achieve the best cleaning effect; 2. After cleaning, the seed cotton needs to be sent to the cotton storage box by an additional fan
