Cotton picker cleaning device and cotton picker

Abstract

The invention discloses a cotton picker cleaning device. The cotton picker cleaning device comprises a water tank, a conveying channel and a power assembly. The water tank comprises a water outlet anda water return port. The conveying channel comprises a water outlet pipe connected with the water outlet, and a water return pipe connected with the water return port. A distributor is connected between the water outlet pipe and the water return pipe. The power assembly is connected with the water outlet pipe and located between the distributor and the water outlet. The distributor is provided with a water spray pipe spraying a spindle assembly. The distributor is provided with a pressure sensor for detecting water pressure in the distributor. The water return pipe is provided with a first control valve for controlling flow of the water return pipe. The opening and closing degrees of the first control valve are adjusted according to detected numerical values of the pressure sensor, thus,the amount of water flowing back into the water tank is adjusted, that is, the water pressure in the distributor is adjusted, so that the water pressure in the distributor and the water pressure of water flowing out of the water spray pipe are kept at certain values, and the cleaning device works stably; and the invention further discloses a cotton picker comprising the cotton picker cleaning device.

Description

technical field [0001] The invention belongs to the field of cotton pickers, and in particular relates to a cotton picker cleaning device and the cotton picker. Background technique [0002] The cotton picker is a large-scale agricultural machinery. The spindle assembly in the picking head is the core component of the cotton picker. In order to make the cotton fall off the spindle assembly smoothly and cool down the spindle assembly, the cotton picker is designed There is a waterway system to drench and moisten each spindle assembly; the water supply of the existing cotton picker waterway system is realized by mechanical power through the V-belt to drive the water pump. Inconvenience is caused, and the V-belt fracture may occur due to the higher rotating speed so that the picking work cannot continue. [0003] The existing waterway structure is not easy to remove the water in the pipeline when it is not working. The temperature difference between day and night in Xinjiang i...

[0002] The cotton picker is a large-scale agricultural machinery. The spindle assembly in the picking head is the core component of the cotton picker. In order to make the cotton fall off the spindle assembly smoothly and cool down the spindle assembly, the cotton picker is designed There is a waterway system to drench and moisten each spindle assembly; the water supply of the existing cotton picker waterway system is realized by mechanical power through the V-belt to drive the water pump. Inconvenience, due to the high speed and the possibility of V-belt breakage, the picking work cannot continue

[0003] The existing waterway structure is not easy to remove the water in the pipeline when it is not working. The temperature difference between day and night in Xinjiang is large, and the night temperature is low during the cotton picking season. When the cotton picker is not working at night, the water in the pipeline will freeze. Ice, so that it will be difficult to supply water to the waterway during the next work, and it is very likely that the water pump will be damaged
