Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a ground film cleaning and recycling machine. Background Art

[0002] Generally, mulch film not only increases ground temperature, retains water, soil, and fertilizer, and improves fertilizer efficiency, but also has multiple functions, such as killing weeds, preventing pests and diseases, preventing drought and waterlogging, inhibiting salt and protecting seedlings, improving light and heat conditions near the ground, and ensuring hygiene and cleanliness. For newly unearthed seedlings, it protects their roots and promotes their growth.

[0003] Ground film is the plastic film that covers the surface of crop fields. Before and after the crops are harvested, the ground film remains in the soil and is difficult to degrade, causing pollution and damage to the soil. Therefore, the recycling of ground film is also an important project in field work.

[0004] There are two traditional methods of recycling ground film: manual recycling, which is to fold the ground film multiple times by manpower. The folded ground film has large gaps, occupies a large space, and is inconvenient to collect and transport. There is also machine recycling, which is composed of mechanisms such as film removal, transportation, film and impurity separation, film collection, and film unloading, and is pulled by a tractor. There are shovel-digging and comb-tooth types. The operation process is complicated, the mechanical equipment is huge, and it is not suitable for flexible operation. Summary of the Invention

[0030] The roller brush is driven by a power system and rotates at a constant speed. It's tilted relative to the vertical frame, meaning it's at an oblique angle to the direction of travel. As the machine moves forward, its bottom edge presses against the mulch film. The rotation of the roller brush creates a lateral force on debris on the mulch film's surface, sweeping dirt, weeds, and other debris sideways out of the cut film's edges, ensuring a clean surface before reeling. As the machine advances through the field, the roller brush's rotational force removes dirt, weeds, and other debris from the film's surface while reeling in the film.

[0031] The mulch film is neatly rolled into a roll by the rotation of the reel. The reel has the function of automatically adjusting the tension to ensure that the mulch film maintains the appropriate tightness during the winding process.

[0032] The cross-axis universal joint coupling is used for torque transmission in mechanical transmission and has a large angular compensation capability. It features high load capacity, wide deviation angle, and high torque transmission. Its compact and rational structure can minimize environmental impact in harsh operating environments. It ensures smooth, stable, and low-noise operation throughout the entire machine operation.

[0033] The ground film cleaning and recycling machine of the utility model has reasonable design, simple structure, safety and reliability, convenient use and easy maintenance, and has good promotion and use value. BRIEF DESCRIPTION OF THE DRAWINGS

[0101] This utility model's mulch film cleaning and recycling machine is specifically designed for use in agricultural mulch film cleaning. Its design aims to efficiently and conveniently remove mulch film remaining in fields and clean the dirt and weeds on its surface. The following is a detailed description of the device's working principle and operating procedures:

[0102] 1. Working Principle:

[0103] The working principle of the ground film cleaning machine is based on the combination of mechanical transmission and roller brush system, and the ground film is cleaned, wound and recovered through a series of mechanical devices. The main principles include the following parts:

[0104] Roller Brush Cleaning System: Equipped with multiple rotating roller brushes, these roller brushes are driven by the power system and rotate at a constant speed. As the machine moves across the field, the roller brushes use the rotational force to sweep away dirt, weeds, and other debris from the surface of the mulch.

[0105] Film Winding System: Behind the brush roller, the machine is equipped with a film winding mechanism. Cleaned film is manually or assistedly guided to the winding mechanism, where the film is neatly rolled into a roll through the rotation of the winding core. The film winding core automatically adjusts tension to ensure the film maintains proper tightness during the winding process.

[0106] Power transmission system: The entire equipment is powered by a built-in engine, electric motor, or hydraulic press to drive the roller brush and film winding mechanism. The transmission system usually uses a belt or chain drive to ensure that all parts work synchronously.

[0107] 2. Operation process:

[0108] (1) Starting the equipment: The operator first starts the power system and adjusts the height and angle of the roller brush and reel according to the laying conditions of the ground film to ensure that the equipment can effectively contact the ground film during operation.

[0109] (2) Entering working state: The equipment starts to move in the direction of laying the ground film. The roller brush system at the front starts to rotate, cleaning the dirt and weeds on the surface of the ground film. The cleaned ground film is guided to the film rolling mechanism.

[0110] (3) Film winding: As the equipment moves forward, the cleaned film is gradually wound onto the winding arm. The winding arm automatically adjusts the tension during the film winding process to ensure that the film is wound evenly and not loose.

[0111] (4) Reel replacement: When a reel is full, the operator can stop the machine to replace the reel. The rolled film can be easily removed from the reel and placed in a designated location for further processing or transportation.

[0112] (5) Complete cleaning: Repeat the above steps until the entire plot of ground film is cleaned. After the equipment completes its work, the operator can perform a simple equipment inspection and maintenance to ensure normal operation next time.

[0113] 3. Notes:

[0114] Roller brush adjustment: Under different field conditions, the operator should adjust the height and rotation speed of the roller brush appropriately according to the depth of the mulch film and the thickness of the soil on the surface to achieve the best cleaning effect.

[0115] Reel tension adjustment: It is very important to ensure that the film is not broken or too loose during the film rolling process. The operator needs to adjust the tension setting of the film reel according to the actual situation.

[0116] Regular maintenance: After using the machine, the operator should regularly check the wear of the roller brush, clean the dirt and weeds attached to the equipment, and lubricate the transmission system to extend the service life of the equipment.

[0117] The above is a description of the basic working principle and operation process of the utility model. By using this machine, agricultural producers can clean the ground film more efficiently, reduce labor intensity and improve production efficiency.
