The fourth belt conveyor 9 is fixedly installed at the top of the closed cover 8. A dust collection device 6 is provided behind the drum screen 2 to treat the sand and dust floating inside the drum screen 2.

[0016] In this embodiment: by setting up a first belt conveyor 1, a drum screen 2, a closed cover 8, and a dust collection device 6, waste agricultural film is fed into the drum screen 2 by the first belt conveyor 1. The drum screen 2 filters and separates the waste agricultural film. The dust generated during the process is sucked away by the closed cover 8 and collected into the dust collection device 6, thus solving the problem of separating and treating dust in the waste agricultural film. After the agricultural film tumbles inside the drum screen 2, it gradually falls into the fourth belt conveyor 9 on the right side. The agricultural film is transported by the fourth belt conveyor 9 and then collected, so it will not be disturbed by the external environment and the dust inside will not float into the air.

[0017] As a technical optimization of this utility model, the bottom of the first belt conveyor 1, the frame 7, and the third belt conveyor 4 are all equipped with movable rollers 15.

The filter cylinder 10 is rotatably installed on the inner side of the drum screen 2, and the feed inlet 11 is located at the left end of the drum screen 2. The bottom end of the fourth belt conveyor 9 is installed corresponding to the right end of the drum screen 2. The drum screen 2 is installed in a state where the left side is higher than the right side at a certain angle, and the second belt conveyor 3 is set parallel to the drum screen 2.

[0020] In this embodiment: by setting up a filter cylinder 10, a fourth belt conveyor 9, and a second belt conveyor 3, waste agricultural film enters the drum screen 2 via the first belt conveyor 1. Inside the drum screen 2, there is a continuously rotating filter cylinder 10, which separates the sand and dust in the waste agricultural film. The sand and gravel filtered out by the filter cylinder 10 accumulates on the second belt conveyor 3 at the bottom of the drum screen 2, and is then transported to the third belt conveyor 4 on the outside. This completes the separation and discharge of sand and gravel from the waste agricultural film. The inside of the drum screen 2 is a sealed space. Except for the feed inlet 11, all other interfaces are equipped with baffles to prevent sand and dust from flying out of the waste agricultural film. After tumbling inside the drum screen 2, the agricultural film gradually falls into the fourth belt conveyor 9 on the right side. The agricultural film is transported by the fourth belt conveyor 9 and then collected, so it will not be disturbed by the external environment, and the sand and dust inside will not float into the air.

[0021] As a technical optimization of this utility model, a second belt conveyor 3 is fixedly installed at the bottom of the drum screen 2, and one end of the second belt conveyor 3 is installed in a corresponding position to one end of the third belt conveyor 4.

[0024] In this embodiment: by setting up a closed cover 8, a dust suction pipe 5, a dust collection device 6, and a fan 12, during the process of processing waste agricultural film, sand and dust will float in the air inside the drum screen 2. The dust isolated by the closed cover 8 is sucked away by the dust suction pipe 5, and the dust is sucked into the dust collection device 6 through the connecting pipe 13. This solves the problem of separating and processing sand and dust in waste agricultural film, and it will not be disturbed by the external environment. The dust inside will not float into the air.

[0025] Working principle: First, waste agricultural film enters the drum screen 2 via the first belt conveyor 1. The continuously rotating filter cylinder 10 inside the drum screen 2 separates the sand and dust from the waste agricultural film. The sand and gravel filtered out by the filter cylinder 10 accumulate on the second belt conveyor 3 at the bottom of the drum screen 2, and are then transported to the third belt conveyor 4 for discharge. This process separates and discharges the sand and gravel from the waste agricultural film. After tumbling inside the drum screen 2, the waste agricultural film gradually falls into the fourth belt conveyor 9 on the right side. The agricultural film is then transported and collected by the fourth belt conveyor 9. At this time, the blower 12 is started, and the dust isolated by the enclosed cover 8 is sucked away through the dust suction pipe 5. The dust is then sucked into the dust collection device 6 through the connecting pipe 13. The dust inside will not float into the air and will not be disturbed by the external environment. The dust inside will not float into the air, thus enabling the pretreatment of waste agricultural film.
