The structure and working principle of the present application will be described in detail below in combination with the drawings.

[0016] As Figures 1 to 6 shown, a film and sundry chopping and throwing separation device for agricultural field collection, comprising a conveyor 1 and a separator frame 2, the conveyor 1 and the separator frame 2 are arranged front and back, as Figure 1 shown, the conveyor 1 includes a conveyor frame 11 and a belt conveyor 12, the conveyor frame 11 is a profile welded part, and the belt conveyor 12 is arranged above the conveyor frame 11, the collected film and sundry mixture is placed on the belt conveyor 12, and the collected film and sundry mixture is conveyed from front to back through the belt conveyor 12.

[0017] As Figure 2 shown, the separator frame 2 includes a housing and a support 21 arranged up and down and fixedly connected, the support 21 is a profile welded part. The housing includes a side plate 22 and a top cover 23, the side plate 22 is arranged left and right, the side plate 22 constitutes the side wall of the housing, and the bottom of the side plate 22 is fixedly connected with the support 21, and the top cover 23 is buckled on the side plate 22, and the whole housing has an inverted U-shaped structure.

[0018] As Figures 3 to 6As shown, the housing of the separating frame 2 has a feeding assembly, a chopping assembly and a throwing assembly arranged in sequence from front to back. The feeding assembly includes a floating feeding roller 3 and a screw feeding roller 4 arranged in sequence. The floating feeding roller 3 is slidingly connected with the side wall of the housing, i.e. slidingly connected with the side plate 22. The screw feeding roller 4 is rotatably connected with the side wall of the housing, i.e. the first end of the screw feeding roller 4 is rotatably connected with the left side plate 22 and the second end of the screw feeding roller 4 is rotatably connected with the right side plate 22. The sliding connection between the floating feeding roller 3 and the side plate 22 allows the spacing between the floating feeding roller 3 and the screw feeding roller 4 to be adjusted, thereby realizing the floating function of the floating feeding roller 3. The floating feeding roller 3 rotates counterclockwise and the screw feeding roller 4 rotates clockwise, and the floating feeding roller 3 and the screw feeding roller 4 work together to compress and feed the film and sundry mixture. Figure 6 As shown, the floating feeding roller 3 is provided with uniformly arranged driving teeth 31 on one half of the outer wall in the circumferential direction, i.e. the driving teeth 31 occupy a circumferential angle of 180 degrees of the floating feeding roller 3. A driven pulley 32 is fixed on the roller shaft of the floating feeding roller 3 and located outside the housing.

[0019] In order to realize the floating assembly of the floating feeding roller 3, the present application is provided with a swing arm 33, the first end of the swing arm 33 is rotatably connected with the chopping roller 5, and the second end of the swing arm 33 is rotatably connected with the floating feeding roller 3. Since the chopping roller 5 is rotatably connected with the side plate 22, the swing arm 33 can drive the floating feeding roller 3 to move along an arc trajectory when it swings, thereby realizing the floating assembly of the floating feeding roller 3. When the material is less or the size is smaller, such as the bulk of the film and sundry mixture, the height of the floating feeding roller 3 is relatively low under its own weight. When the material is more or the size is larger, such as the bundle of the film and sundry mixture, the material pushes the floating feeding roller 3 to move upwards to adapt to the situation of more or larger material, thereby realizing the feeding of more or larger material while maintaining the compression and compaction of the material.

[0020] In order to realize the rotation driving of the floating feeding roller 3, a driving pulley 53 is fixed on the chopping roller 5, the driving pulley 53 is located outside the housing, and the driving pulley 53 and the driven pulley 32 are connected by a belt. When the chopping roller 5 drives the driving pulley 53 to rotate, the driving pulley 53 drives the rotation of the driven pulley 32 through the belt, thereby driving the rotation of the floating feeding roller 3.

[0021] As shown, Figure 7 The screw feeding roller 4 includes coaxially arranged first and second screw rollers 41 and 42, and the rotational directions of the first and second screw rollers 41 and 42 are arranged to concentrate the material to the middle part of the screw feeding roller 4. The screw feeding roller 4 is located at the discharge end of the belt conveyor 12, so that the material on the belt conveyor 12 is caught by the screw feeding roller 4 after falling down. The floating feeding roller 3 contacts the film and sundry mixture under its own weight and works together with the screw feeding roller 4 to compact the film and sundry mixture.

[0022] As Figures 4 to 6 shown, the chopping assembly includes a chopping roller 5, which is rotationally connected with the side plate 22 of the housing, rotates counterclockwise, and has a chopping cutter 51 on the outer wall thereof. The chopping roller 5 has a C-shaped chopping screen 7 on the periphery thereof, the inside of the chopping screen 7 is a chopping cavity, the first end of the chopping screen 7 is connected with the spiral feeding roller 4, the second end of the chopping screen 7 is located at the rear side of the floating feeding roller 3 and is closely arranged, and the chopping roller 5 is located inside the chopping screen 7. The rear wall of the chopping screen 7 has a lateral screen hole 71, and the bottom wall of the chopping screen 7 has a bottom screen hole 72, the aperture of the bottom screen hole 72 is smaller than that of the lateral screen hole 71. When the chopping roller 5 rotates, the chopping cutter 51 directly chops and scatters the film and sundry mixture after contacting the film and sundry mixture. In addition, the chopping roller 5 also cooperates with the chopping screen 7 to chop and scatter the film and sundry mixture. The soil and straw with a smaller outer size fall to the outside of the chopping cavity through the bottom screen hole 72 of the chopping screen 7, and the residual film and straw with a larger outer size enter the throwing area through the lateral screen hole 71 at the rear side of the chopping screen 7.

[0023] To realize the assembly of the chopping cutter 51, the outer wall of the chopping roller 5 has a cutter seat 52 arranged in a spiral direction, and the first end of the chopping cutter 51 is hingedly connected with the cutter seat 52. When the chopping roller 5 rotates, the chopping cutter 51 is swung, and the swung chopping cutter 51 is arranged radially along the chopping roller 5 under the action of centrifugal force. The cutter seat 52 does not occupy the entire circumference of the chopping roller 5, the chopping cutter 51 is arranged on the non-entire circumference of the chopping roller 5, and the central angle of the outer wall of the chopping roller 5 occupied by the chopping cutter 51 is between 270 degrees and 340 degrees. The residual film is a flexible body and is easy to deform. The chopping cutter 51 does not occupy the entire circumference of the chopping roller 5, and the pawl 31 is not uniformly arranged on the entire circumference of the floating feeding roller 3, mainly considering the characteristics of the film and sundry, so as to neither excessively compress and crush the film and sundry nor produce ineffective cutting, so as to improve the separation efficiency of the film and sundry.

[0024] As Figures 4 to 6As shown, the throwing assembly comprises the upper and lower throwing roller 6 and throwing screen 8, the outer wall of the throwing roller 6 is provided with throwing fan leaves 61 uniformly distributed in the circumferential direction, and every two adjacent throwing fan leaves 61 are axially staggered along the throwing roller 6. The front end of the throwing screen 8 extends between the support 21 and the shell, and the rear end of the throwing screen 8 is provided with throwing screen holes 81 for screening the straw with small outer size, so as to screen out the straw with small outer size from the throwing area. The throwing screen 8 is in a circular arc structure, the first end of the throwing screen 8 is in contact with the outer wall of the chopping screen 7, and the first end of the throwing screen 8 is located at the boundary between the lateral screen hole 71 and the bottom screen hole 72. The residual film and straw with large outer size entering the throwing area through the lateral screen hole 71 in the chopping cavity fall on the front end of the throwing screen 8, and when the throwing roller 6 rotates, the throwing fan leaves 61 scrape the straw and residual film on the throwing screen 8 and throw them to the rear side. Since the density of the straw is greater than that of the residual film, the falling points of the straw and the residual film are different from the throwing roller 6 and have a large difference, that is, the falling point of the straw is far from the chopping roller 6, and the falling point of the residual film is close to the chopping roller 6, so as to realize the effective separation of the residual film and the straw.

[0025] The present application realizes the compression and feeding of the film and sundry mixture by the cooperation of the floating feeding roller 3 and the spiral feeding roller 4, is convenient for controlling the feeding amount and is suitable for the continuous feeding of the film and sundry bale or bulk material in the farmland. The spiral feeding roller is arranged to feed the film and sundry mixture to the middle after the film and sundry mixture is collected, and the compressed film and sundry mixture is scattered and chopped by the rotation of the chopping roller. The soil and straw with small outer size fall to the outside of the chopping cavity through the bottom screen hole of the chopping screen, and the residual film and straw with large outer size enter the throwing area through the lateral screen hole at the rear side of the screen. The straw with small outer size falls to the outside of the throwing area through the throwing screen hole, and the residual film and straw with large outer size are thrown to the rear side, the density difference between the straw and the residual film is utilized to complete the throwing with different distances, so as to realize the effective separation of the straw and the residual film and complete the whole machine operation. The present application integrates the feeding assembly, the chopping assembly and the throwing assembly in the shell, and the feeding assembly, the chopping assembly and the throwing assembly are sequentially connected in front and back, so that the whole machine has small size, the chopping is immediately performed after the feeding, the throwing and screening are immediately performed after the chopping, and the processes are seamlessly connected, so that the screening efficiency is high.
