Telescopic cotton stalk pulling device and pulling method

Abstract

The invention relates to the technical field of cotton stalk pulling equipment, in particular to a telescopic cotton stalk pulling device and a pulling method. A power device in the pulling device is connected with the harvesting structure through a transmission shaft. The end of a rotating shaft in the harvesting structure is connected with the rack. The driving end of the rotating shaft is connected with the output end of the transmission shaft. The roller assemblies are arranged in the axial direction of the rotating shaft. A cavity allowing the clamping jaw to retract is formed in a shell in the roller assembly. And a turntable of which the center line is offset from the axis of the rotating shaft is arranged in the cavity. And one end of the connecting part of the clamping jaw is hinged with the shell, and the other end is connected with the turntable through a connecting rod. According to the pulling device, the power device is used for driving the rotating shaft to rotate, then the roller assembly is driven to rotate, the clamping jaws do telescopic motion in the radial direction of the rotating disc, the forward traction effect of traction power equipment on the rack is matched, the grabbing parts of the clamping jaws clamp and pull cotton stalks, and the problem that the roots of the cotton stalks are left in a cotton field is effectively solved; and the pulling efficiency is further improved, and the pulling operation effect is improved.

Description

technical field [0001] The invention relates to the technical field of cotton stalk extraction equipment, in particular to a retractable cotton stalk extraction device and extraction method. Background technique [0002] As one of the indispensable crops for human life, cotton has a long history in China. Among them, Xinjiang is the main cotton growing area in China. According to the survey of the National Cotton Information Network, in 2020, the cotton planting area in Xinjiang will reach 34.927 million mu, accounting for 76.7% of the national cotton planting area, and the output will reach 4.822 million tons, accounting for 85.8% of the country's total output. Cotton will produce a lot of by-products when it is picked, and cotton stalk is one of the most important by-products of cotton. Cotton stalk is a renewable biomass resource that can be burned as fuel, processed into feed for poultry, and used in papermaking, board making, edible fungus culture, environmental prote...

Problems solved by technology

However, when the pulling device is used in the field, it can only pull out two rows of cotton stalks at a time, and the strip gap needs to be designed according to the row spacing of the cotton stalks, and it is difficult to meet the needs of large-scale mechanized operations in cotton fields.
