Cotton picker

Abstract

The invention provides a cotton picker. The cotton picker comprises a cotton picking handle, a hose, a cotton-air separation box, a centrifugal fan and a case. A handle is arranged on the case, and the handle is arranged on the upper portion of the case. One end of the cotton picking hose is connected with a separation box shell, and a suction head is arranged at the other end of the cotton picking hose. A wind closing wheel is arranged on the lower portion of the separation box, and cotton is conveyed to a cotton outlet. A cotton collecting bag is arranged on the outlet. A motor is arranged on the lower portion in the case, the motor transmits torque to a rotary shaft of the wind closing wheel through a gear reducer, a large belt wheel is arranged on the rotary shaft of the wind closing wheel, a small belt wheel is arranged on a rotary shaft of a screen, rotational motion of the wind closing wheel is also transmitted to the screen through belt drive, the rotating speed of the screen is far higher than that of the wind closing wheel, and large centrifugal force is generated. The cotton picker is high in suction power and more reasonable in structure, the cotton hull separation rate is high, and cotton and cotton seed separation rate is higher.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a cotton picker. Background technique [0002] my country is a big cotton production country and also a big cotton consumption country. In 2009 / 2010, my country's cotton production accounted for 30.6% of the global cotton production. Every year when the cotton is mature, the problem of cotton picking has been troubled by cotton farmers. Due to the high purchase cost of large cotton picking machines, the picked cotton contains a lot of impurities, the cotton fibers are damaged, and large cotton picking machines are only suitable for large areas of flat fields. Cotton farmers prefer hand picking. Although the quality of hand-picked cotton is guaranteed, the picking efficiency is low. In the cotton picking season of the year, there is often a shortage of cotton pickers, and the labor cost for picking cotton is also a considerable expenditure. [0003] At present, the small co...

Problems solved by technology

There are two ideas in the overall design of the suction cotton picker. One idea is that the inhaled cotton passes through the rotating impeller with the airflow, and then is used out of the impeller together. This cotton picker does not have a separation device for cotton and airflow. The structure is relatively simple, but the quality of the cotton fiber obtained is extremely poor, and it is prone to clogging; another way of thinking is that before the cotton enters the impeller, the cotton and the air flow are separated by a certain device, and the cotton picker is used for picking The quality of cotton has been improved, but because of the different separation devices, the quality of cotton and the effect of cotton gas separation are also different
