Detailed Implementation

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figures 1-4 This utility model provides a waste agricultural film plastic pellet washing device, which includes a rotatable washing cylinder 2. The washing cylinder 2 is equipped with a stirring component and filled with quartz sand. A first frame 3 is provided below the washing cylinder 2. A second frame 5 is fixed at the bottom of the first frame 3. A water collection frame 9 is fixed at the bottom of the second frame 5. A screening screen 4 is fixed inside the first frame 3. A mesh plate 6 is fixed inside the second frame 5. A base 1 is provided at the bottom of the water collection frame 9. A plurality of springs 19 are evenly arranged between the top of the base 1 and the bottom of the water collection frame 9. A vibration motor 20 is symmetrically fixed on the outer side of the first frame 3.

[0025] The agricultural film fragments and quartz sand to be cleaned are fed into the cleaning drum 2. Under the action of the stirring component, the agricultural film fragments and quartz sand are vigorously mixed and rubbed, which helps to effectively remove the dirt and other impurities adhering to the surface. The cleaned agricultural film fragments are poured into the screening screen 4 by the rotation of the cleaning drum 2. The vibrating motor 20 and the spring 19 work together to vibrate and screen. The mixture of quartz sand and agricultural film fragments is screened through the screening screen 4 to separate the cleaned agricultural film fragments. The quartz sand falls onto the screen plate 6, and the wastewater falls through the screen plate 6 into the water collection frame 9 for discharge. The quartz sand can be discharged from the screen plate 6 for subsequent recycling.

[0026] The first frame 3, the second frame 5, and the water collection frame 9 all have an opening structure on one side. The second frame 5 has a spiral feeder 10 on one side of the opening. The top of the spiral feeder 10 has a discharge pipe 14 facing the cleaning cylinder 2. The bottom of the spiral feeder 10 has a hopper 21 located below the opening of the second frame 5. The second frame 5 has a downwardly inclined feeding plate 7 fixed on the side near the opening. The feeding plate 7 has symmetrically inclined guide plates 8 fixed on it. The guide plates 8 form a feeding port between their opposite ends. The feeding port and the hopper 21 are arranged vertically to allow the quartz sand to fall into the hopper 21. The spiral feeder 10 is fixed on the top of the base 1. A water supply pipe 15 is fixed on one side of the discharge pipe 14. The water supply pipe 15 is also inclined towards the cleaning cylinder 2 and is used to inject water into the cleaning cylinder 2 for cleaning.

[0027] The quartz sand on the mesh plate 6 is conveyed to the inside of the hopper 21 through the feed plate 7 and the feed port. The quartz sand is then conveyed back to the inside of the washing cylinder 2 through the screw feeder 10 and the discharge pipe 14, which facilitates recycling and better continuous cleaning work. This avoids the troublesome problem of manually feeding quartz sand, making it more convenient and efficient to use.

[0028] The top of the base 1 is symmetrically fixed with L-shaped brackets 11. Each bracket 11 is rotatably connected to a rotating shaft 12. The washing cylinder 2 is fixed between the rotating shafts 12. A first motor 13 is fixed on one side of one of the brackets 11. The rotating shaft 12 is fixedly connected to the output shaft of the first motor 13. The first motor 13 drives the rotating shaft 12 to rotate, which drives the rotation of the washing cylinder 2. The rotating washing cylinder 2 facilitates the pouring of the mixture of quartz sand and agricultural film fragments inside the washing cylinder 2 onto the screen 4 for subsequent separation of agricultural film fragments and quartz sand.

[0029] The stirring assembly includes a fixed plate 16 fixed to the top of the cleaning cylinder 2, a stirring paddle 17 rotatably connected inside the fixed plate 16, and a second motor 18 fixed to the top of the fixed plate 16. The top end of the stirring paddle 17 is fixedly connected to the output shaft of the second motor 18.

[0030] The second motor 18 drives the stirring paddle 17 to stir, causing the agricultural film fragments and quartz sand to rub against each other inside the cylinder, removing surface mud and other impurities and ensuring a good cleaning effect.

[0031] The mesh size of the screening mesh 4 is larger than that of the quartz sand particles, which facilitates the interception of agricultural film fragments after washing, allowing the quartz sand to fall onto the mesh plate 6. The mesh size of the mesh plate 6 is smaller than that of the quartz sand particles, preventing the quartz sand from falling onto the water collection frame 9. The bottoms of the screening mesh 4, mesh plate 6, and water collection frame 9 are all inclined to facilitate the discharge of agricultural film fragments, quartz sand, and wastewater after washing.

[0032] Working principle: The agricultural film fragments and quartz sand to be cleaned are fed into the cleaning cylinder 2. The second motor 18 drives the stirring paddle 17 to stir, so that the agricultural film fragments and quartz sand rub against each other inside the cylinder, removing the surface mud and other impurities, and ensuring a good cleaning effect.

[0033] The first motor 13 drives the rotating shaft 12 to rotate, which in turn drives the rotation of the washing cylinder 2. The rotating washing cylinder 2 facilitates the pouring of the mixture of quartz sand and agricultural film fragments inside the washing cylinder 2 onto the screen 4 for subsequent separation of agricultural film fragments and quartz sand.

[0034] The washed agricultural film fragments are poured into the screening screen 4 by the rotating washing drum 2. The vibrating motor 20 and the spring 19 work together to vibrate and screen the film. The mixture of quartz sand and agricultural film fragments is screened through the screening screen 4 to separate the washed agricultural film fragments. The quartz sand falls onto the screen plate 6, and the wastewater falls through the screen plate 6 into the water collection frame 9 for discharge. The quartz sand can be discharged from the screen plate 6 for subsequent recycling.

[0035] The quartz sand on the mesh plate 6 is conveyed to the inside of the hopper 21 through the feeding plate 7 and the feeding port. The quartz sand is then conveyed back to the inside of the washing cylinder 2 through the screw feeder 10 and the discharge pipe 14, which facilitates recycling and better continuous cleaning work. This avoids the troublesome problem of manually feeding quartz sand, making it more convenient and efficient to use.

[0036] By combining the friction of quartz sand with mechanical stirring, the removal rate of impurities such as mud is improved, achieving efficient cleaning. Furthermore, the combination of components such as the screening screen 4, screen plate 6, and vibrating motor 20 enables the separation of sand, agricultural film fragments, and sewage. The sand can be recycled for cleaning through the screw feeder 10, avoiding the troublesome problem of manually feeding quartz sand, making it more convenient and efficient to use.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
