Technical Field

The invention belongs to the field of agricultural machines and tools, and particularly relates to a residual film recycling and collecting roller and a film collecting method thereof.

Background

With the popularization of the planting technology of the protected land, the planting area covered by the mulching film also tends to increase, but as the residual film cannot be effectively recycled in time, the yield of crops and the sustainable development of agriculture are seriously influenced and white pollution is caused as the quantity of the residual film in the soil increases year by year. The data show that: the residual mulch is not cleaned in three continuous years, and the wheat yield is reduced by 2% -3%; the corn yield is reduced by about 10 percent; the cotton yield is reduced by 10-15%, so that the ecological environment and sustainable development of the farmland can be protected only by controlling the residual film pollution, and the research on residual film recycling machines and tools becomes the key for further popularization and development of the plastic film mulching technology.

The film collecting roller of the residual film recycling machine is a key part influencing the performance of the whole machine, and the quality of the structural design of the film collecting roller is directly related to the film collecting rate of the residual film. The film collecting roller of the existing residual film recycling machine mostly adopts a fixed rake tooth type, residual films penetrate through the rake tooth or rake is grabbed on the roller, and when the roller rotates to the upper part, the separation of the films is realized. However, the residual film is recovered by the above method, the residual film is easy to adhere to the rake teeth after being punctured, and the residual film is more disadvantageously separated due to the relatively dense arrangement of the rake teeth.

Therefore, we propose a residual film recycling and collecting roller and a film collecting method thereof to solve the above problems.

In the residual film recycling and collecting roller, the rotating shaft penetrates through two ends of the roller and is movably connected with the roller, and the movable chambers are arranged on two sides of the roller.

In the film collecting roller for recovering the residual film, one end of the telescopic assembly close to the magnetic core penetrates through the roller, and one end of the telescopic assembly far away from the magnetic core penetrates through the roller and is communicated with the outside.

In the residual film recycling and collecting roller, the buffer plate is internally provided with the air guide holes, and the lower ends of the telescopic teeth are conical.

A film collecting method of a residual film recycling and collecting roller comprises the following steps:

s1, placing the film collecting roller on the ground, freely adjusting the grounding depth through a movable spring, repelling the telescopic assembly to the lower part of the magnetic core by the magnetic core, moving the telescopic bottom block and the telescopic teeth in the direction far away from the magnetic core, piercing residual films through the tips of the telescopic teeth, and bringing the residual films to the telescopic teeth;

s2, when the telescopic teeth are far away from the magnetic core, through the air guide rod, negative pressure formed in the telescopic groove drives external air flow to enter the suction chamber through the suction port and be sucked into the telescopic groove, the effect is that suction is formed on the ring side of the telescopic teeth, residual films wound on the telescopic teeth are sucked to the upper side, and the residual film recycling effect is better;

s3, when the telescopic component rotates to the upper part of the magnetic core, the telescopic bottom block and the telescopic teeth move towards the direction close to the magnetic core under the attraction of the magnetic core, and the residual film attached to the telescopic teeth is dislocated with the roller through the suction opening along with the contraction of the telescopic teeth, so that the residual film can be conveniently separated;

s4, when the telescopic teeth are close to the magnetic core, the gas in the telescopic grooves is extruded, is discharged into the suction chamber through the gas guide rod and is discharged outwards through the suction port, and the effect is that the blowing effect is formed at the suction port, so that the residual film is more easily separated from the roller.

Compared with the prior art, the invention has the advantages that:

1. the magnetic core is fixedly connected with the rotating shaft, the telescopic assembly in the roller and the magnetic core generate relative displacement along with the rotation of the roller, when the telescopic assembly is positioned at the lower part of the magnetic core, the telescopic bottom block and the telescopic teeth are popped up under the repulsive force of the magnetic core, the residual film is punctured and wound on the telescopic teeth through the telescopic teeth, meanwhile, negative pressure is formed in the telescopic groove, and suction is formed at a suction opening through the air guide rod and the suction chamber, so that the residual film is better wound on the telescopic teeth; when the telescopic assembly is positioned on the upper part of the magnetic core, the telescopic bottom block and the telescopic teeth contract to extrude gas in the telescopic groove by receiving the suction force of the magnetic core, and the gas is sprayed out through the suction port, so that the separation of the residual film and the roller is facilitated.
