A kind of blowing suction type cotton conveying pipe for cotton picker

Abstract

The invention discloses a blowing-suction type cotton conveying pipeline for a cotton picker and belongs to the field of pneumatic cotton conveyance of cotton pickers. The blowing-suction type cotton conveying pipeline for the cotton picker comprises a flow distribution pipe and a blowing-suction switching air pipe, the flow distribution pipe comprises a first air opening, a second air opening and a third air opening, the blowing-suction switching air pipe comprises an air inlet, an air suction opening and an air blowing opening, the air inlet is positioned in the middle of the blowing-suction switching air pipe, and the air suction opening and the air blowing opening are positioned at two ends of the blowing-suction switching air pipe respectively. The first air opening of the flow distribution pipe is connected with the air inlet of the blowing-suction switching air pipe and enables air to enter towards the direction of the air blowing opening, the second air opening is connected with a blower, the third air opening is connected with an upper air opening of a picking head, and the air suction opening of the blowing-suction switching air pipe is connected with a lower air opening of the picking head while the air blowing opening of the blowing-suction switching air pipe is connected with a cotton box. The blowing-suction type cotton conveying pipeline for the cotton picker has the advantages that blowing air to the picking head and suction of cotton into the cotton box can be achieved by the aid of the single blower, cotton left in the picking head is reduced, maintenance period and service life of the cotton picker are prolonged, and cotton picking efficiency of the cotton picker can be improved.

Description

technical field [0001] The invention relates to a pipe, more specifically, to a blowing-suction cotton conveying pipe for a cotton picker. Background technique [0002] The range of cotton planting in my country is quite extensive. In the past, cotton picking mainly relied on manual picking, which was labor-intensive and inefficient. With the development of agricultural machinery, some cotton pickers have appeared on the market one after another. Electric cotton pickers can effectively increase the speed of manual cotton picking and generate income for cotton pickers. [0003] The pneumatic cotton conveying system is an important part of the cotton picker, and its working performance has an important influence on the whole cotton picking system. The pneumatic cotton conveying system is mainly composed of a fan and a cotton conveying pipeline. There are various cotton conveying methods for cotton pickers on the market. The common pneumatic cotton conveying method is: the blo...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiency that a single air blower cannot simultaneously absorb the cotton in the picking head and transport the cotton to the cotton box in the cotton conveying process of the existing cotton picker, and provide a blowing and suction conveying method for the cotton picker. Cotton pipeline, adopting the technical solution of the present invention, can realize the function of blowing the picking head and sucking and blowing the cotton into the cotton box with a single blower, which minimizes the cotton left in the picking head and prevents the picking head from being blocked , prolong the maintenance cycle and service life of the cotton picker; at the same time, it can improve the cotton picking efficiency of the cotton picker
