Description

Mulching film collecting machine for cotton field

Technical Field

The invention relates to agricultural mechanical equipment, in particular to a mulching film collecting machine for a cotton field.

Background

In cotton planting, a large amount of mulching films are required to be covered to preserve soil moisture, after cotton is harvested in autumn, a large amount of mulching films are left on a cotton field, if the mulching films are not recovered or removed in time, the mulching films can be turned into the ground when soil is prepared in spring, and a large amount of residual mulching films are accumulated under the ground in the past. As is well known, the residual film is difficult to degrade in soil, and very serious white pollution is formed over time, so that the yield and the quality of the cotton planted subsequently are reduced. Therefore, it is very important to recover the mulching film of the cotton field.

In order to solve the problem of mulching film recovery, some scientific research units and colleges are actively testing various mechanical equipment, a straw smashing and film removing all-in-one machine is mostly adopted to recover mulching films, a centrifugal flail knife is usually used for smashing and removing straws, meanwhile, circulating chain type spike teeth are required to stretch into a shallow layer on the ground surface to pick up the mulching films, the mulching films are smashed in the process of smashing the straws by the centrifugal flail knife, the mulching films are broken and are difficult to pick up to a recovery box, the spike teeth are circularly transferred back to a cotton field, only few parts can be recovered, and in addition, even if a small amount of broken mulching films are recovered, the mulching films are difficult to recycle.

Referring to fig. 1, the invention discloses a cotton field film collecting machine, which comprises a frame 1, wherein a film cutting assembly 2, a picking mechanism 3, a material transferring mechanism 4 and a bundling machine 6 are sequentially arranged on the frame 1 from front to back.

Further referring to fig. 4 and 5, 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-up and picking-up claws 32 arranged on the chain 31, each row of picking-up and picking-up claws 32 comprises a plurality of picking-up and picking-up claws 32 arranged at intervals, and the chain 31 is used for driving each row of picking-up and picking-up claws 32 to dig up the mulching film upwards and stir the mulching film backwards; the material transferring mechanism 4 comprises a rotating shaft 41 rotatably mounted on the frame 1, at least one row of material transferring claws 42 are mounted on the rotating shaft 41 along the circumferential direction, each row of material transferring claws 42 comprises a plurality of material transferring claws 42 arranged at intervals, and each row of material transferring claws 42 can be staggered with any row of picking-up and raking claws 32 to avoid arrangement so as to transfer the mulching film; the bundling machine 6 is used for collecting and bundling the transferred mulching film.

It will be appreciated that the frame 1 may be a self-propelled work vehicle, and that the frame 1 may be powered by connection to an agricultural tractor or other towing vehicle, and may also be provided with hydraulic and electrical power. 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 cotton 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 actual positions of the material transferring claw 42 and the picking-up claw 32 are considered, the rotation directions of the chain 31 and the rotating shaft 41 are kept consistent, such as clockwise direction shown in fig. 4, so that when the material transferring claw 42 and the picking-up claw 32 meet, the picking-up claw 32 has a downward moving trend, the material transferring claw 42 has an upward moving trend, and each row of the material transferring claw 42 and each row of the picking-up claw 32 can correspond to each other one by one.

When the frame 1 walks forwards, the picking-up claws 32 extend into earth surface soil of a cotton field, the picking-up claws 32 are circularly driven by the chain 31, so that a row of picking-up claws 32 on the front lower side of the chain 31 can upwards pick up a mulching film to separate the mulching film from the soil, the mulching film is dragged forwards to enable the mulching film to be stacked and upwards support the mulching film, the film cutting knife 21 can transversely and quickly move along the guide rail 22 to cut off the part of the supported mulching film which is still connected with the ground, the row of picking-up claws 32 continuously rotate and backwards stir the mulching film, and then the mulching film on the picking-up claws 32 is transferred to the bundling machine 6 by the material rotating claw 42 to be bundled.

Because each row of the picking-up claws 32 and the material transferring claws 42 are arranged at intervals and can be staggered and avoided, the mulching film is usually in a strip shape and spans the picking-up claws 32 or the material transferring claws 42, so that each row of the material transferring claws 42 smoothly unload the mulching film from the picking-up claws 32, the mulching film is transferred and recovered to the bundling machine 6, and then the mulching film is collected to the bundling machine by combining the forward motion of the frame 1, the mulching film is not easy to tear off midway, the mulching film cannot be crushed, and the complete mulching film can be picked up and bundled, the mulching film has the value of reutilization, and can continuously enter the next film collecting period.
