[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] like Figures 1 to 6As shown, the residual film sorting device of an embodiment of the present invention includes a box body 100, a stirring unit 200, a de-impurity unit 300 and a conveying unit 400. The top of the box body 100 is open, and the box body 100 is filled with water. The lower end of the stirring unit 200 extends into the box body 100, and the stirring unit 200 is used to stir the material in the box body 100. In the direction of material movement, the de-impurity unit 300 is located downstream of the stirring unit 200, and the de-impurity unit 300 is used to remove debris floating on the water surface. In the direction of material movement, the conveying unit 400 is located downstream of the de-impurity unit 300, and one end of the conveying unit 400 extends into the box body 100, and the conveying unit 400 is used to remove residual film in the box body 100.

[0031] Specifically, if Figure 1 As shown, the housing 100 is fixed to the frame and filled with water. The bottom of the housing 100 has a water inlet and a water outlet. The stirring unit 200, the impurity removal unit 300, and the conveying unit 400 are arranged in sequence along the front-to-back direction. A feed hopper 12 is also provided at the front end of the stirring unit 200, and the outlet of the feed hopper 12 is connected to the interior of the housing 100.

[0032] It should be noted that because the residual film is severely weathered and damaged in the soil, it has many holes and strong water absorption. After standing in water for a certain period of time, it can completely sink into the water, while impurities such as straw will float on the water surface. Therefore, the residual film can produce a good separation effect by being soaked in water and continuously stirred.

[0033] The residual film sorting device of the present invention utilizes the large difference in the suspension characteristics of the residual film mixture after breaking in water and the migration movement law under the disturbance of the stirring unit 200, and the different specific gravities of different residual films in water to achieve film-soil separation. At the same time, the method of washing the residual film with water can prevent the secondary pollution of the residual film when cleaning the residual film, and can improve the quality of residual film sorting. At the same time, the soil separated by sedimentation can be reused in the residual film recovery process, achieving sustainable development. The water is stirred by the stirring unit 200, and the residual film and debris are stirred by the power of the water flow. The residual film and debris move to the impurity removal unit 300 under the action of the water flow. The impurity removal unit 300 removes the debris floating on the water surface to achieve separation of the residual film and debris. Finally, the underwater residual film is removed by the conveying unit 400 and conveyed out of the box 100. Compared with related technologies

[0034] In some embodiments, the stirring unit 200 includes a first stirring component 1, a second stirring component 2 and a driving component 3. The first stirring component 1 and the second stirring component 2 both include a stirring shaft 101, a stirring blade 102 and a protective tube 13. The stirring blade 102 is connected to the stirring shaft 101, the stirring shaft 101 is connected to the driving component 3, and the stirring shaft 101 is rotatable relative to the box body 100. The protective tube 13 is mounted on the outside of the stirring shaft 101 and the stirring blade 102. A plurality of filter holes 131 are provided on the outer wall of the protective tube 13 to connect the inner and outer sides of the protective tube 13.

[0035] Specifically, if Figure 2 and Figure 3 As shown, the first stirring component 1 and the second stirring component 2 are arranged at intervals in the left-right direction, the driving component 3 is between the first stirring component 1 and the second stirring component 2, the stirring shaft 101 extends in the up-down direction, the lower end of the stirring shaft 101 is connected to the stirring blade 102, the upper end of the stirring shaft 101 is connected to the driving component 3, the protective tube 13 is sleeved on the outside of the stirring shaft 101 and the stirring blade 102, and a plurality of filter holes 131 are provided in the lower part of the protective tube 13.

[0036] It should be noted that the direction of the stirring shaft 101 in the first stirring assembly 1 is opposite to the direction of the stirring shaft 101 in the second stirring assembly 2. For example, when the stirring shaft 101 in the first stirring assembly 1 is clockwise, the stirring shaft 101 in the second stirring assembly 2 is counterclockwise, or when the stirring shaft 101 in the first stirring assembly 1 is counterclockwise, the stirring shaft 101 in the second stirring assembly 2 is clockwise.

[0037] In the residual film sorting device of the embodiment of the present invention, the stirring shaft 1013 rotates to drive the stirring blade 102 to rotate, and the stirring blade 102 stirs the water in the box body 100, and the water flows out of the protective tube 13 through the filter hole 131. Since the stirring shaft 101 in the first stirring component 1 and the stirring shaft 101 in the second stirring component 2 have different directions, the water flows generated by the two stirring blades 102 collide to form a combined force, which pushes the residual film from underwater toward the impurity removal unit 300.

[0038] In some embodiments, the drive assembly 3 includes a driver 31, a first output shaft 32 and a second output shaft 33, the driver 31 is connected to the first output shaft 32 and the second output shaft 33 respectively, the first output shaft 32 is connected to the stirring shaft 101 in the first stirring assembly 1, and the second output shaft 33 is connected to the stirring shaft 101 in the second stirring assembly 2.

[0039] Specifically, if Figure 2 and Figure 3As shown, the driver 31 can be a motor, and the output end of the motor is connected to a first output shaft 32 and a second output shaft 33 respectively. The first output shaft 32 drives the stirring shaft 101 in the first stirring assembly 1 to rotate through a bevel gear transmission structure, and the second output shaft 33 drives the stirring shaft 101 in the second stirring assembly 2 to rotate through a bevel gear transmission structure. By having a single motor simultaneously drive the stirring shaft 101 in the first stirring assembly 1 and the stirring shaft 101 in the second stirring assembly 2 to rotate, the equipment investment cost can be reduced and the rotation synchronization of the first stirring assembly 1 and the second stirring assembly 2 can be ensured.

[0040] In some embodiments, the debris removal unit 300 includes a debris removal roller 4, multiple debris removal blades 5 and a debris removal barrel 6. The debris removal roller 4 extends along the width direction of the box body 100. The multiple debris removal blades 5 are respectively connected to the debris removal roller 4, and the multiple debris removal blades 5 are arranged at intervals along the circumference of the debris removal roller 4. The debris removal barrel 6 and the debris removal roller 4 are arranged at intervals in the length direction of the box body 100, and the debris removal barrel 6 has an opening on the side facing the debris removal roller 4, so that the debris removal blades 5 can drive the debris floating on the water surface into the debris removal barrel 6.

[0041] Specifically, if Figure 1 and Figure 4 As shown, the debris removal roller 4 extends in the left-right direction, and a plurality of debris removal blades 5 are evenly spaced along the circumference of the debris removal roller 4. The debris removal drum 6 and the debris removal roller 4 are spaced apart in the front-to-back direction, that is, the debris removal roller 4 is located in front of the debris removal drum 6. The front of the debris removal drum 6 has an opening, and the size of the opening in the left-right direction is greater than or equal to the size of the debris removal roller 4 in the left-to-right direction. By providing the debris removal blades 5, debris or residual film floating on the water surface can be peeled off from the water surface. By providing the debris removal drum 6, the debris or residual film peeled off by the debris removal blades can be transported out of the box 100, thereby improving the residual film sorting effect.

[0042] In some embodiments, the impurity removal unit 300 also includes a first collecting box 7 and a conveying roller 8. The first collecting box 7 is connected to the box body 100, and the first collecting box 7 is connected to the impurity removal barrel 6. The conveying roller 8 extends along the width direction of the box body 100. The conveying roller 8 is arranged in the impurity removal barrel 6 to drive the impurities in the impurity removal barrel 6 into the first collecting box 7.

[0043] Specifically, if Figure 1 and Figure 5 As shown, the first collection box 7 is located on the side of the box body 100. The upper end of the first collection box 7 has an opening. The conveyor roller 8 is installed in the impurity removal drum 6. The outer wall of the conveyor roller 8 is provided with a threaded conveyor plate. When the conveyor roller 8 rotates, the material in the impurity removal drum 6 is driven by the conveyor roller 8 to move toward the first collection bucket. By providing the first collection box 7 and the conveyor roller 8, debris can be discharged in a timely manner, preventing debris from accumulating in the impurity removal drum 6 and improving the efficiency of residual film sorting.

[0044] In some embodiments, the conveying unit 400 includes a conveyor belt 9 and multiple conveyor scrapers 10. One end of the conveyor belt 9 extends below the water surface, and the other end of the conveyor belt 9 extends out of the box 100. The multiple conveyor scrapers 10 are arranged at intervals along the transmission direction of the conveyor belt 9.

[0045] Specifically, if Figure 1 and Figure 6 As shown, the conveyor belt 9 is arranged at an angle with the front lower and the back higher. The front end of the conveyor belt 9 extends below the water surface, and the rear end of the conveyor belt 9 extends out of the box 100. The conveying scrapers 10 are evenly spaced along the extension direction of the conveyor belt 9. By arranging the conveyor belt 9 and the conveying scrapers 10, the residual film below the water surface can be scraped and transported out of the box 100, thereby realizing the collection and transportation of the residual film and improving the efficiency of residual film sorting.

[0046] In some embodiments, a plurality of drainage holes 91 are provided on the conveyor belt 9 , and the plurality of drainage holes 91 are evenly distributed on the conveyor belt 9 .

[0047] Specifically, if Figure 1 and Figure 6 As shown, the drain holes 91 are evenly distributed on the conveyor belt 9. By setting the drain holes 91, the water on the residual film can be drained out, and the soil carried on the residual film can also fall into the box body 100 through the drain holes 91. Subsequently, the box body 100 is cleaned regularly, and the soil in the box body 100 is cleaned and returned to the field.

[0048] It should be noted that the conveyor belt 9 is driven to rotate by a motor and a drive roller, and the motor and the drive roller are both located outside the box 100 , that is, the motor and the drive roller are located at the rear end of the conveyor belt 9 .

[0049] In some embodiments, the conveying unit 400 further includes a second collecting bucket 11 , which is connected to a side of the conveying belt 9 away from the water surface.

[0050] Specifically, if Figure 1 and Figure 2 As shown, the upper end of the second collecting box is open, and the residual film conveyed by the conveyor belt 9 falls into the second collecting box through the opening for collection. The residual film is collected by the second collecting box, thereby improving the effect of residual film recovery.

[0051] Refer to the following Figures 1 to 6 The operation process of the residual film sorting device according to the embodiment of the present invention is described.

[0052] The material enters the housing 100 through the feed hopper 12. After soaking and settling, it gradually separates. The drive assembly 3 then drives the first and second stirring assemblies 1 and 2 to rotate. The rotation of the stirring blades 102 connected to the stirring shaft 101 generates a water flow that is discharged through the filter holes 131. The water flows generated by the two stirring shafts 101 rotating in opposite directions collide, creating a combined force that pushes the residual film from underwater toward the rear of the conveyor. Simultaneously, the impurity removal roller 4 drives the impurity removal blades 5 to rotate. These impurity removal blades 5 throw debris floating on the water surface backward into the impurity removal drum 6. The conveyor roller 8, using its spiral structure, transports the debris to the first collection box 7. When the residual film in the water reaches the vicinity of the conveyor belt 9, it is scraped off by the conveyor scraper 10 on the conveyor belt 9 and transported to the second collection box at the rear end of the conveyor belt 9. The water and some soil that are swept up with the residual film fall back into the housing 100 through the drain holes 91. Through repeated processes, pollution-free residual film recovery can be achieved.
