Description

Technical Field

[0001] This invention relates to the field of agricultural film recycling devices, and in particular to a recycling device and its method of use with strong adsorption capacity for agricultural film residue. Background Technology

[0002] Plastic mulch film plays a vital role in modern agriculture, serving functions such as warming and moisture retention, preventing pests, suppressing weed growth, and promoting crop growth. It is an essential agricultural production material for high and stable yields, currently occupying over 17.5 million hectares in my country. However, plastic mulch film can remain in the soil for approximately 300 years. With the increasing use and age of the film, large amounts of residue remain in the soil, causing pollution and damage. This disrupts soil structure, hinders crop emergence, impedes root growth, and leads to reduced crop yields, resulting in widespread "white pollution" and severe negative impacts on the agricultural ecological environment. This has become a prominent issue facing the green development of agriculture.

[0003] Most existing agricultural mulch films are non-magnetic. When recycling mulch films, current mulch film recycling devices can generally only recover up to 80% of the film, leaving 20% ​​of the film residue unrecoverable. This is mainly because the film residue fragments are small. To solve this problem, non-magnetic mulch films have been replaced with magnetic mulch films. However, existing mulch film recycling machines still leave 20% of the magnetic film residue unrecoverable. To address this issue, a magnetic film residue recycling device has been developed to improve the recycling efficiency of agricultural mulch films. Summary of the Invention

[0004] The purpose of this invention is to provide a special magnetic film recycling device that can recycle the remaining 20% ​​of magnetic film using the principle of magnetic adsorption, and has a good recycling effect.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A recycling device with strong adsorption capacity for agricultural film residue includes a traditional mechanical film recycling machine. The traditional mechanical film recycling machine includes a frame, a film lifting shovel, a soil penetration depth adjustment device, a transmission gearbox, a transmission device, a conveyor belt, a material collection scraper, a collection box, and ground support wheels. The front end of the frame is connected to the rear end traction frame of a tractor. The front end of the transmission gearbox is connected to the rear end output shaft of the tractor, and the transmission device transmits power to the traditional mechanical film recycling machine and the magnetic film residue adsorption and recycling device respectively.

[0007] It also includes a magnetic residual film adsorption and recovery device, which is installed on the frame 1.0 to 1.5m behind the traditional mechanical film recycling machine by riveting and is driven by a transmission gearbox;

[0008] The aforementioned magnetic residual film adsorption and recovery device includes a drive roller, a magnetic conveyor belt, an adjustable pressure roller, a transmission roller, a residual film collection and scraping device, and a residual film collection box; the drive roller is connected to the transmission roller; the transmission roller is connected to the magnetic conveyor belt; the magnetic conveyor belt is equipped with a residual film collection and scraping device at its end; and a residual film collection box is located at the rear end of the residual film collection and scraping device.

[0009] The transmission method of the aforementioned transmission gearbox is one or a combination of gear transmission, worm gear transmission, and chain transmission, used to drive the magnetic residual film adsorption and recovery device.

[0010] The length of the aforementioned drive roller and transmission roller is 1.7 to 2.6 m, which can be adjusted according to the single film width of the planting mode. The diameter is no more than 4 / 5 of the diameter of the support wheel. A transmission device is installed on the shaft end of the drive roller to connect with the transmission gearbox and transmit power to the drive roller.

[0011] The magnetic conveyor belt has a width of 1.5 to 2.4 m and is made of rubber or plastic. The magnetic conveyor belt is equipped with strip-shaped strong magnetic materials, namely neodymium iron boron magnets. Each magnetic strip is 3 cm wide and the interval between adjacent magnetic strips is 3 cm. The magnetic conveyor belt is equipped with adjustable pressure rollers.

[0012] The aforementioned residual film collection box is welded from thin-walled, non-magnetic stainless steel plates, and its dimensions match the width of the magnetic conveyor belt.

[0013] The above-mentioned recycling device with strong adsorption capacity for agricultural film residue is characterized in that the film collection and scraping device includes a transmission device, a transmission roller, a plate-shaped rubber scraper, and a brush, wherein one end of the plate-shaped rubber scraper is fixed on the transmission roller, and the other end is fixedly provided with a brush.

[0014] A method for using a recycling device with strong adsorption capacity for agricultural film residue, the recycling device comprising the following operating steps: when recycling agricultural magnetic mulch film, a film-lifting shovel lifts the magnetic mulch film from the ground surface, conveys it upwards via a conveyor belt, and scrapes the magnetic mulch film into a collection bin via a scraping device; the remaining magnetic mulch film on the ground surface is recycled by a magnetic film residue adsorption and recycling device. During recycling, a transmission gearbox on the frame drives a drive roller via a transmission device, thereby driving the magnetic conveyor belt to run. Magnetic strips on the magnetic conveyor belt adsorb the magnetic film residue, which then moves with the magnetic conveyor belt to the upper surface of the conveyor belt and is conveyed obliquely upwards to the upper end, where the film residue collection scraping device collects the film residue and places it into the film residue collection bin. Beneficial effects

[0015] This invention incorporates a magnetic residual film adsorption and recovery device at the rear of the frame. Approximately 80% of the magnetic film is first recovered using a mechanical recovery device, and then the remaining 20% ​​is recovered using the magnetic residual film adsorption and recovery device. This improves the residual film recovery efficiency and yields good results. The invention has a simple structure, is easy to operate, and has promising prospects for widespread application.
