Problems solved by technology

[0003] In the above-mentioned mulching film recycling method, three independent devices are required to complete the film lifting, horizontal film cutting and vertical film cutting. This affects the recovery efficiency of the plastic film, and the above-mentioned film picking mechanism adopts the structure of setting jaws on the chain plate. The transmission of the chain plate, the moving speed of the chain plate is not as fast as the rotor. When the frame moves forward at a faster speed, the chain plate and the The film picking structure of the jaws is difficult to completely pick up the relatively dense blocky residual film

Embodiment 1

[0075] A film recovery mechanism, comprising a film-lifting and splitting rotor 1 and a pin-type film-picking rotor 2 arranged in sequence backward from the forward direction of a frame; the film-raising and splitting rotor 1 includes a plurality of discs coaxially arranged with the splitting rotor Shape film cutting knife 11 and a plurality of plate-shaped film cutting knives 12 perpendicular to disc-shaped film cutting knife 11; Described nail type film picking rotor 2 includes many rows of tooth nails 21 distributed on the outer edge of the film picking rotor; The outer edge linear velocity of the film splitting rotor 1 is greater than the forward speed of the frame.

[0076] The plate-shaped film removing knife 12 includes a mounting plate 121 arranged along the normal direction of the wheel shaft and a film removing knife body 122 fixed on the mounting plate 121 . The plate-shaped film-lifting knife 12 is inclined 1-45 degrees to the rotation direction along the normal di...

Embodiment 2

[0081] A film recovery mechanism, comprising a film-lifting and splitting rotor 1 and a pin-type film-picking rotor 2 arranged in sequence backward from the forward direction of a frame; the film-raising and splitting rotor 1 includes a plurality of discs coaxially arranged with the splitting rotor Shape film cutting knife 11 and a plurality of plate-shaped film cutting knives 12 perpendicular to disc-shaped film cutting knife 11; Described nail type film picking rotor 2 includes many rows of tooth nails 21 distributed on the outer edge of the film picking rotor; The outer edge linear velocity of the film splitting rotor 1 is greater than the forward speed of the frame.

[0082] The plate-shaped film removing knife 12 includes a mounting plate 121 arranged along the normal direction of the wheel shaft and a film removing knife body 122 fixed on the mounting plate 121 . The plate-shaped film-lifting knife 12 is inclined 1-45 degrees to the rotation direction along the normal di...

Embodiment 3

[0087] A kind of plastic film recovery method, comprises the following steps:

[0088] S1: The power drive device drives the frame to advance towards the area to be operated;

[0089] S2: The cutter group of rotor 1 cuts the surface film into blocks and throws the block film and soil to the rear;

[0090] S21: The earth retaining plate 3 is hit by the soil together with the massive plastic film, the soil is broken, and after falling, the plastic film is located on the soil surface;

[0091] S3: The pin-type film-picking rotor 2 rotates in the opposite direction to the film-lifting and dividing rotor 1, and picks up the film along the retaining plate 3 and transports it backward;

[0092] S4: The comb 41 of the comb-type film-removing rotor 4 brushes out the plastic film on the tooth nail 21; with the cooperation of the comb-type brush 41-type film-guiding and soil-clearing rotor 5, the plastic film is transported to the film collecting bucket.

[0093] The limit speed on the o...

Abstract

The invention belongs to the technical field of agricultural machinery, and in particular relates to a film recovery mechanism and a recovery method; through the film lifting and splitting rotors and the nail-type film picking rotors arranged in sequence backward from the forward direction of the frame, and through a simple and compact mechanical structure, more Efficiently realize film lifting, cutting and picking film recycling. By setting a plurality of disc-shaped film cutting knives coaxial with the split rotor and a plurality of plate-shaped film cutting knives perpendicular to the disc-shaped film cutting knives on the film-cutting and splitting rotor, compared with the traditional technology, there is no need for cutting The edge film is shoveled out from the soil before, so that the lateral support of the film is more stable during the cutting process. Since the outer line speed of the film splitting rotor is higher than the forward speed of the frame, the horizontal film cutting, vertical film cutting and loosening are realized. The function of the soil, the structure is simpler and more compact, while saving the cost of mechanical manufacturing, it greatly improves the efficiency of residual film recycling.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a film recovery mechanism and recovery method. Background technique [0002] Authorized notification number is that the Chinese patent of CN106612650B discloses a kind of mulch film recycling method, comprises four steps of film lifting, cutting film, picking film, collecting, and during its operation, implement moves forward along seedling row. Since the edge of the mulch film is buried in the soil, the shovels installed on both sides will shovel the edge of the mulch film out of the soil in order to stir it up. Then, after cutting by the horizontal film cutting mechanism and the vertical film cutting mechanism, the film is finally cut into rectangular blocks, and then the film lifting lever is driven by the film lifting mechanism to generate a reciprocating stirring motion, and the film lifting lever lifts the blocky film. And stuff it into the clamp...
