Referring to the figure 1, the utility model discloses a plastic film pickup attachment, including frame 1, the frame is installed in proper order by preceding to the back and is cut membrane module 2, pickup mechanism 3 and workbin 4.

Referring to fig. 2, the film cutting assembly 2 includes a film cutting knife 21 and a guide rail 22 arranged along the left-right direction, and the film cutting knife 21 is slidably connected with the guide rail 22; the picking mechanism 3 comprises a chain 31 and a plurality of rows of picking and raking claws 32 arranged on the chain 31, and the chain 31 is used for driving each row of picking and raking claws 32 to dig up the mulching film and shift the mulching film backwards; the bin 4 is used for collecting the stirred mulching films.

It will be appreciated that the frame 1 may be a self-propelled work vehicle, or may be connected by a tow bar to an agricultural tractor or other towing vehicle to provide power to the frame 1. The specific process of the picking-up claw 32 for digging up the mulching film means that the picking-up claw 32 extends into the soil on the ground surface of the cultivation field and drags the mulching film forwards, so that the mulching film is stacked and then is lifted upwards to be completely separated from the soil. After the mulching film is dug up, the film cutting knife 21 moves transversely and rapidly along the guide rail 22 to cut off the dug-up mulching film part still connected with the ground.

When the frame 1 travels forwards, the picking-up and raking claws 32 extend into soil on the ground surface of a cultivated field, the picking-up and raking claws 32 are circularly driven by the chain, so that a row of picking-up and raking claws 32 on the front lower side of the chain 31 can pick up a mulching film upwards to separate the mulching film from the soil, the mulching film is dragged forwards to stack the mulching film and then upwards support the mulching film, the film cutting knife 21 can transversely and quickly move along the guide rail 22 to cut off the supported mulching film part still connected with the ground, the row of picking-up and raking claws 32 continuously rotate and backwards stir the mulching film, the mulching film is collected to the material box 4 by combining the action of the forward travel of the frame 1, the mulching film is difficult to break midway, the mulching film cannot be crushed, the complete mulching film can be picked up and recovered, the mulching film has the value of recycling, and then the picking.

In some embodiments of the present invention, the pick-up mechanism 3 further includes a driven sprocket 33 and a driving sprocket 34 which are distributed in the front-back direction, the chain 31 is in transmission connection with the driving sprocket 34 and the driven sprocket 33, wherein the chain 31 rotates clockwise as shown in fig. 2, so that the driving sprocket 34 drives the upper side of the chain 31 to move backwards, the upper side of the chain 31 can also be called as the tight side of the chain 31, and the straight portion above the chain 31 is referred to.

In order to install the picking-up claws 32, a plurality of support bars 35 are installed on the chain 31 along the front-back direction, a plurality of support bars 35 are arranged on the left side and the right side of the chain 31 at intervals, the support bars 35 are fixedly connected with the plurality of chains 31 along the left-right direction, and each row of picking-up claws 32 are correspondingly and uniformly installed on the support bars 35.

The length of support bar 35 corresponds the width that matches the plastic film, take the cotton field as an example, according to the planting characteristics in cotton field, can adopt once to reap the triplex row straw, and triplex row's plastic film width is 2.0 ~ 2.1 meters, and on this basis, the length of support bar 35 is a bit bigger than 2.1 meters, and pickup mechanism 3 is equipped with 2 to 8 rows of picking up and taking off claws 32 altogether, and each row has 16 ~ 20 picking up and taking off claws 32, and the array density is big, the vacancy is few, picks up completely.

In addition, at least partly install between two adjacent chains 31 and leak native otter board 36, leak native otter board 36 and be the roll board or the screen cloth that are the fretwork form, leak native otter board 36 and chain 31 synchronous rotation, most earth can be when the plastic film is shoveled the time and the plastic film phase separation, but the plastic film probably has a small amount of earth, in the in-process that picks up the claw 32 and stir the plastic film backward, earth falls on leaking native otter board 36 to can drop back again to the farmland through leaking native otter board 36, guarantee that the plastic film of retrieving is clean, have reuse's value.

With further reference to fig. 3, the height of the film cutting knife 21 relative to the frame 1 is adjustable to adapt to the height of the mulching films in different ground conditions.

Specifically, the film cutting assembly 2 further comprises a height adjusting frame 23 and a sliding block 24, the height adjusting frame 23 is connected with the guide rail 22 in a sliding mode, a vertical screw rod 25 and a vertical guide rod 26 are installed on the height adjusting frame 23, the sliding block 24 is connected with the guide rod 26 in a sliding mode and connected with the screw rod 25 in a threaded fit mode, the film cutting knife 21 is fixedly installed on the sliding block 24, and the purpose of adjusting the height of the film cutting knife 21 is achieved by rotating the screw rod 25.

In addition, as shown in fig. 1, the pickup device further comprises a bundling machine 5, the bundling machine 5 is communicated with the rear end of the material box 4, the bundling machine 5 can bundle mulching films, an emptying door of the bundling machine 5 can be automatically opened to discharge the mulching film bundles, the emptying door is automatically closed to perform the next bundling cycle, the bundling machine 5 of the embodiment is a conventional bundling machine, and particularly, the bundling machine in the application of the utility model with the application number of CN201920541031.6 or the invention with the application number of CN201911023661.5 can be adopted.
