Portable backpack cotton picking and seed removing device

Technical Field

The invention relates to the technical field of agricultural machinery, in particular to a portable backpack cotton picking and seed removing device.

Background

The cotton needs to be picked after being ripe, the cotton is generally picked manually, the manual picking workload is large, the strength is high, the picking efficiency is low, the time is long, and the picked cotton is easy to adhere impurities due to the fact that the strength is not well controlled. With the improvement of science and technology, mechanical equipment for picking cotton is available nowadays, but most of the existing cotton picking equipment has complex structure, many parts and unstable performance; and the body type is bigger, the price is more expensive, it is not convenient to carry, the flexibility is not enough.

There are some technical solutions related to cotton picking in the prior art, for example, a patent of application No. CN206251635U discloses a portable cotton picking device, when picking cotton, a control switch on a handle is pressed, a storage battery supplies power to an electric roller and a fan, and the electric roller and the fan start to operate. After the electric roller rotates, the first gear, the first roller and the first conveying belt are driven to rotate in an operation mode, and the electric roller, the first roller and the first conveying belt rotate anticlockwise on the whole. Because the first gear on the motorized pulley is meshed with the second gear on the second pulley, the third pulley and the second conveyor belt run and rotate simultaneously, and the second pulley, the third pulley and the second conveyor belt rotate clockwise on the whole. When the fan operates, negative pressure is formed in the cotton collecting box, the conveying pipe and the shell, so that picked cotton can smoothly enter the cotton collecting box. The cotton is placed at a cotton inlet of the shell, because the first conveyor belt and the second conveyor belt run in opposite directions, the cotton is extruded by the two conveyor belts and cotton needles on the two conveyor belts and enters a cotton extrusion conveying channel formed between the lower belt surface of the first conveyor belt and the upper belt surface of the second conveyor belt, the cotton is transmitted to a cotton outlet along with the transmission of the conveyor belts, when the cotton reaches the cotton outlet, the cotton is blocked by the upper baffle plate or the lower baffle plate, and then the cotton is sucked into the cotton collecting box through the conveying pipe under the action of the fan, so that the cotton picking is completed. This technical scheme can realize the harvesting of cotton, but the big difficult portable use of weight of the device volume, and the cotton needle can twine the cotton and finally cause the jam when the device is picked, and the device can't realize going the seed of cotton through the harvesting that can realize the cotton simultaneously.
