Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural equipment, and in particular relates to a ground film recovery and film conveying device and a ground film recovery machine constituted by the device. Background Art

[0002] The application of mulch film planting mode has become a standard mode, especially in the arid areas of northern China. However, it also brings about serious mulch film pollution problems.

[0003] After a planting season, recycling of the mulch film also becomes a necessary operation.

[0004] However, although there are many machines for recycling mulch films at present, the effect is not satisfactory, especially for machines for recycling mulch films after crop harvest. The first is to use a raking method for recycling, and the recycled mulch films are mixed with crop straw. The recycled mulch films and crop straw cannot be further utilized, and are rarely used at present.

[0005] The second method is to peel off the film and recycle and pack the peeled film. This method mainly uses a film-lifting shovel or a plow to shovel the film. This method of peeling off the film consumes a lot of power, especially when the land is severely compacted after the crops are harvested, and the failure rate is very high. For example, a film recovery mechanism and a film recovery machine formed by it disclosed in CN208353835U are no longer widely used.

[0006] The third method involves using the film collection device's own toothed rakes to lift the film, which is then transported and packaged. Examples include the film recycling machines disclosed in CN215188301U and CN213819136U. These recycling machines utilize a chain rake mechanism for both film removal and transport. Due to the differences in the nature of film removal and transport, these two tasks can only be prioritized in practice. If film removal is prioritized, transport must also be prioritized, resulting in poor transport performance or increased transport costs. Furthermore, if transport is prioritized, the effectiveness of the film removal operation may be compromised.

[0007] Therefore, a mulch film recovery and film conveying device which is aimed at the mulch film recovery operation after crop harvest and can take into account both the mulch film recovery and conveying operations and the mulch film recovery operation machine constituted thereby have emerged. Summary of the Invention

[0008] The utility model aims to provide a mulch film recovery and conveying device which is aimed at the mulch film recovery operation after crop harvest and can take into account both mulch film recovery and conveying operations, and a mulch film recovery operation machine constituted by the device.

[0011] The conveying mechanism comprises a conveying belt mechanism composed of at least two conveying rollers (23) and a conveying belt (21), and the conveying belt (21) is provided with densely distributed finger-shaped nail teeth (24).

[0012] The film-lifting mechanism is located below the conveying mechanism, and when the spikes (24) of the conveying mechanism move to the lower part, the ends of the spikes (24) are located in the annular grooves (44) of the first film-lifting roller (41) of the film-lifting mechanism.

[0015] Furthermore, the film-lifting tooth expansion groove (45) is preferably a tubular hole on a ring protruding outward on the drum wall of the second film-lifting drum (42).

[0016] Furthermore, the film-forming teeth (43) are elastic teeth.

[0017] Furthermore, the conveying belt (21) of the above-mentioned conveying mechanism is composed of multiple parallel strips, and at least the surface of the upper conveying roller (23) is provided with a grooved V-shaped or U-shaped wheel, and the flange diameter of the upper conveying roller (23) is greater than or equal to the height dimension of the film-forming teeth (43) standing upright.

[0018] Furthermore, the above-mentioned conveying mechanism is composed of at least three conveying rollers (23) and a conveying belt (21) to form a conveying belt mechanism, and at least two of the conveying rollers (23) form an inverted triangle conveying belt mechanism with a larger upper portion and a smaller lower portion.

[0019] Furthermore, the conveying mechanism is preferably arranged upright on the frame (13).

[0020] Furthermore, the belt surface at the front of the conveying belt mechanism of the conveying mechanism is preferably upright or inclined forward, that is, the front belt surface of the conveying belt mechanism forms an angle less than or equal to 90 degrees with the ground.
