[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-Figure 6 The present invention provides a drum screen type waste mulch film and impurity sorting device, comprising a feed box 1 for initially separating soil and mulch film, the top of the feed box 1 is fixedly connected and communicated with a feed hopper 3, the feed box 1 is connected with a sorting box 2 through a conveying auger 4, the sorting box 2 is provided with a drum screen machine 21 for re-separating soil and mulch film, the screen cylinder 35 of the drum screen machine 21 is provided with a film suction component for removing the mulch film, and one end of the film suction component extending out of the sorting box 2 is connected with a first vacuum cleaner.

[0029] The present invention performs primary separation of soil and ground film through the feed box 1, and then separates the soil and ground film again through the drum screen 21, and removes the ground film in the screen cylinder 35 of the drum screen 21 through the film suction component, thereby effectively improving the separation efficiency of soil and ground film.

[0030] In a further optimized solution, a first feed port 15 is provided on one side of the top surface of the feed box 1 away from the sorting box 2, and the first feed port 15 is fixedly connected and communicated with the feed hopper 3, so that the soil and the ground film enter the feed box 1 through the feed hopper 3.

[0031] In a further optimized solution, a guide plate 11 is symmetrically arranged below the first feed port 15, and the two guide plates 11 are fixedly connected to the top surface of the feed box 1. Rolling rollers 12 are symmetrically arranged below the two guide plates 11, and the two rolling rollers 12 are rotatably connected to the opposite inner walls of the feed box 1. The soil is rolled and crushed by the two rolling rollers 12, so that the ground film embedded in the soil can be separated from the soil.

[0032] Further optimization scheme, a vibrating conveyor 13 is arranged below the two rolling rollers 12, the vibrating conveyor 13 is arranged obliquely, the higher end of the vibrating conveyor 13 is arranged below the two rolling rollers 12, and an inclined plate 14 is arranged below the lower end of the vibrating conveyor 13, and the inclined plate 14 is fixedly connected with a first discharge port 16, and the first discharge port 16 is opened on the outer wall of the feed box 1 facing the sorting box 2. The vibrating conveyor 13 can keep the soil and the ground film in a loose state, which is convenient for re-separation.

[0033] After the soil and ground film enter the first feed port 15, they fall along the guide plate 11 between the two rolling rollers 12. The ends of the drive shafts of the two rolling rollers 12 extending outside the feed box 1 are fixedly connected to motors respectively. The motors are fixedly connected to the outer wall of the feed box 1. The two motors work synchronously to make the two rolling rollers 12 rotate relative to each other. The soil is crushed by the two rolling rollers 12 to separate the soil and the ground film. After separation, the soil and the ground film fall onto the vibrating conveyor 13, and the soil and the ground film are vibrated and conveyed by the vibrating conveyor 13, so that the soil and the ground film always remain in a loose state during the transportation process and enter the conveying auger 4.

[0034] According to a further optimized solution, the first discharge port 16 is fixedly connected and communicated with the feed end of the conveying auger 4 .

[0035] According to a further optimized solution, the discharge end of the conveying auger 4 passes through the second feed port 22 of the sorting box 2 and extends into the screen drum 35 of the drum screen machine 21 .

[0036] The soil and the ground film are fed into the drum screen 21 through the conveying auger 4.

[0037] The screen drum 35 of the drum screen machine 21 separates the soil and the ground film by rotation. Since the soil has a greater density than the ground film, the soil falls out of the screen drum 35 through the screen holes on the screen drum 35 and accumulates at the bottom of the drum screen machine 21. The ground film is retained in the screen drum 35 due to its low density and light weight.

[0038] A further optimized solution is that the film suction assembly includes a second exhaust duct 6 arranged in the screen cylinder 35 of the drum screen machine 21, and the second exhaust duct 6 is symmetrically provided with an air inlet plate 24. The second exhaust duct 6 extends out of the sorting box 2 at one end thereof and is connected to the second vacuum cleaner, and the second exhaust duct 6 is fixedly connected to the sorting box 2.

[0039] A further optimized solution is that a cavity is opened in the air inlet plate 24, and the cavity is arranged in a T shape. The end of the cavity with a larger opening is fixedly connected to and communicated with the second exhaust duct 6, and the end of the cavity with a smaller opening faces the inner wall of the screen drum 35 of the drum screen machine 21.

[0040] When the second vacuum cleaner is turned on, the ground film in the sieve drum 35 enters the cavity of the air inlet plate 24 under suction, and enters the second vacuum cleaner along the second exhaust pipe 6, so that the ground film in the sieve drum 35 can be effectively removed.

[0041] In a further optimized solution, a second discharge port 23 is provided at the lower part of the sorting box 2 away from the feed box 1. The soil accumulated at the lower part of the drum screen 21 can be collected through the second discharge port 23.

[0042] A further optimized solution is that a plurality of hydraulic cylinders 31 are arranged on one side of the feed hopper 3, the fixed end of the hydraulic cylinder 31 is fixedly connected to the top surface of the feed box 1, the telescopic ends of the hydraulic cylinders 31 are commonly fixedly connected to a connecting plate 32, one end of the connecting plate 32 is fixedly connected to a support plate 33, the support plate 33 is arranged above the feed hopper 3, and a plurality of cylinders 34 are fixedly connected to the support plate 33 on one side facing the feed hopper 3.

[0043] In order to prevent the soil and ground film from clogging the feed hopper 3, when the soil and ground film in the feed hopper 3 do not move downward, the piston end of the hydraulic cylinder 31 is retracted, and the piston end of the hydraulic cylinder 31 drives the connecting plate 32 to descend, and the connecting plate 32 drives the supporting plate 33 to descend, and the supporting plate 33 drives several cylinders 34 to descend. After the cylinder 34 extends into the feed hopper 3, it can push the soil and ground film to the top of the rolling roller 12, so that the soil and ground film can effectively pass through the feed hopper 3 into the feed box 1.

[0044] In order to prevent large amounts of dust from being generated in the feed box 1 during the conveying process of the vibrating conveyor 13, the top surface of the feed box 1 is fixedly connected and communicated with a first exhaust duct 5. One end of the first exhaust duct 5 extends into the feed box 1, and the other end of the first exhaust duct 5 is communicated with a first vacuum cleaner. The dust in the feed box 1 can be removed by the first vacuum cleaner, thereby effectively removing lighter impurities in the soil and ground film.

[0045] Working process: firstly, the piston end of the hydraulic cylinder 31 is extended to make the cylinder 34 away from the feed hopper 3, and the cylinder 34 is placed above the feed hopper 3, so that the cylinder 34 does not affect the soil and ground film entering the feed hopper 3, and the soil and ground film enter the guide plate 11 through the feed hopper 3, and the soil and ground film fall along the guide plate 11 to between the two rolling rollers 12, and the two motors work synchronously to make the two rolling rollers 12 rotate relative to each other, and the soil is rolled and crushed by the two rolling rollers 12, so that the soil embedded in the soil is The ground film can be separated from the soil. After separation, the soil and the ground film fall to the vibrating conveyor 13. The soil and the ground film are vibrated and conveyed by the vibrating conveyor 13, so that the soil and the ground film are always kept in a loose state during the conveying process and lighter impurities can be suspended. At this time, the first vacuum cleaner is synchronously turned on to allow the dust in the feed box 1 to enter the first vacuum cleaner through the first exhaust duct 5, which not only reduces the dust in the feed box 1, but also removes the lighter impurities in the soil and the ground film; soil The soil and the ground film enter the feeding end of the conveying auger 4 through the inclined plate 14. The conveying auger 4 conveys the soil and the ground film to the drum screen 21. The sieve drum 35 of the drum screen 21 separates the soil and the ground film by rotation. Since the soil has a greater density than the ground film, the soil falls out of the sieve drum 35 through the sieve holes on the sieve drum 35 and accumulates at the bottom of the drum screen 21. The ground film is left in the sieve drum 35 due to its low density and light weight. At this time, the second vacuum cleaner is turned on. The end with the larger cavity opening is fixedly connected and communicated with the second exhaust duct 6, and the end with the smaller cavity opening faces the inner wall of the screen cylinder 35 of the drum screen machine 21, so that the air inlet plate 24 can effectively suck the ground film in the screen cylinder 35 into the cavity of the air inlet plate 24, and the ground film enters the second vacuum cleaner along the second exhaust duct 6, so that the ground film in the screen cylinder 35 can be effectively removed, and the recovered ground film is recovered by the second vacuum cleaner, and the soil accumulated at the bottom of the drum screen machine 21 can be collected through the second discharge port 23.

[0046] When the soil and ground film in the feed hopper 3 do not move downward, the piston end of the hydraulic cylinder 31 is retracted, and the piston end of the hydraulic cylinder 31 drives the connecting plate 32 to descend, and the connecting plate 32 drives the supporting plate 33 to descend, and the supporting plate 33 drives several cylinders 34 to descend. After the cylinder 34 is extended into the feed hopper 3, the soil and ground film can be pushed to the top of the rolling roller 12, so that the soil and ground film can effectively pass through the feed hopper 3 into the feed box 1, and then the piston end of the hydraulic cylinder 31 is extended to move the cylinder 34 away from the feed hopper 3, and the cylinder 34 is placed above the feed hopper 3, so that the cylinder 34 does not affect the soil and ground film entering the feed hopper 3.
