Film-picking and film-unloading mechanism for residual film recovery of straight-rod crops

Abstract

The invention belongs to the field of minitype agricultural machinery, and in particular relates to a film-picking and film-unloading mechanism for residual film recovery of straight-rod crops. A frame is connected with a profiling frame; a break shovel is arranged under the middle of the frame; a film-picking component and a film-unloading component are arranged in parallel on the profiling frame according to front and back positions; a first transmission wheel and a second transmission wheel which synchronously move are arranged on a drive shaft of the film-picking component; a third transmission wheel is arranged on a drive shaft of the film-unloading component; the first transmission wheel is connected with a traction mechanism through a chain; the second transmission wheel and the third transmission wheel are driven by the chain; film-rising shovels are arranged behind the film-picking component and on the profiling frame under the film-unloading component; and a film collection box is arranged at the rear end of the profiling frame. The mechanism is reasonable in arrangement, simple in structure and reliable in film-picking and film-unloading, low in cost and is convenient and feasible, and is convenient to mount and repair; and moreover, the mechanism can continuously operate, and the film can be picked cleanly.

Description

technical field [0001] The invention belongs to the field of small-scale agricultural machinery, and in particular relates to a mechanism for picking up and unloading residual film of straight-stem crops, which is particularly suitable for picking up residual film of corn, sorghum and other fields with hard roots. Background technique [0002] Since the film mulching cultivation technology was introduced into my country in the late 1970s, with its remarkable characteristics of increasing temperature, retaining moisture, inhibiting the growth of weeds, and increasing crop yields, it has greatly increased crop production, shortened the growth period of crops, and brought forward the growth of crops. A practical technology listed on the market has been welcomed by farmers and has been rapidly promoted in many places in our country. At present, in my country's Xinjiang, Shandong, Shanxi, Heilongjiang, Gansu and other cold, arid and semi-arid regions, plastic film mulching cultiva...

Problems solved by technology

However, on the one hand, this machine completely rolls the film on the film roll. When unloading the film, it is necessary to cut the film from the middle with a knife to unload the film. Unloading the film is cumbersome and difficult.

On the other hand, the film-winding wheel is a follower wheel without driving, and the film-winding is unreliable because the plastic elongation of the residual film is not compensated.
