DETAILED DESCRIPTION

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] In this embodiment, the polyethylene waste corresponds to a polyethylene drip tape, and may also be other polyethylene films, that is, polyethylene waste with continuity, which is suitable for continuous transmission.

[0020] according to Figure 1 - Figure 3 The present embodiment proposes a polyethylene waste efficient cleaning and crushing device, including an outer box body 1. The outer box body 1 is a split design, which is divided into an upper box body 22 and a lower box body 23. The upper box body 22 is mainly used to set corresponding cleaning and drying components, while the lower box body 23 is used to set crushing components. The upper box body 22 and the lower box body 23 are detachably connected to facilitate subsequent maintenance and cleaning of the equipment.

[0021] A collecting plate 2 is provided on the inner side of the outer box body 1, and a collecting chamber 20 is provided on the inner side of the collecting plate 2. The upper end of the collecting chamber 20 is connected with the outside, and is used to collect cleaning liquid. The corresponding lower end of the collecting chamber 20 is arranged in an arc-shaped protrusion. Liquid outlets 21 are provided on both sides of the collecting plate 2, and the liquid outlets 21 are connected with the collecting chamber 20. Due to the arc-shaped protrusion, the liquid in the middle part of the collecting chamber 20 will flow to both sides, so it can better cooperate with the liquid outlet 21. A pipe is installed on the liquid outlet 21, which passes through the outer box body 1 and is connected to an external pumping device or a water storage device for liquid recovery.

[0022] Above the collection plate 2, there is a spray pipe rack 3. The position of the spray pipe rack 3 corresponds to the position of the collection chamber 20. The spray pipe rack 3 is connected to the outer box body 1 through a bracket, and a flushing head 4 is installed on the spray pipe rack 3. In this embodiment, six groups of flushing heads 4 are evenly arranged and are evenly distributed on the upper and lower sides of the spray pipe rack 3. Thus, when polyethylene waste (waste drip irrigation tape) enters, the space it passes through corresponds to the position of the flushing head 4. Therefore, the upper and lower surfaces of the polyethylene waste can be washed simultaneously by the flushing head 4 to remove the stains on its surface. The liquid generated during the cleaning process enters the collection chamber 20. Specifically, the inside of the spray pipe rack 3 is hollow and has the effect of liquid transmission. A water supply pipe 24 is installed above the outer box body 1, and the water supply pipe 24 is connected to an external water supply device and the spray pipe rack 3.

[0023] On both sides of the spray pipe rack 3, there are traction components, and the traction components are connected to the outer box body 1. The traction components include two symmetrically arranged lower traction rollers 16. Above the lower traction rollers 16, there are upper traction rollers 17, and the upper traction rollers 17 are driven by a third motor. The third motor is located outside the outer box body 1 and is connected to the outer box body through a bracket. At the same time, the shafts of the lower traction rollers 16 and the upper traction rollers 17 are connected to the outer box body 1 through bearings. During operation, the polyethylene waste (waste drip irrigation tape) itself has continuity and flexibility. Therefore, when it enters the outer box body 1, it will pass through the space between the lower traction rollers 16 and the upper traction rollers 17. At this time, the lower traction rollers 16 and the upper traction rollers 17 are in contact with the polyethylene waste (waste drip irrigation tape) at the same time. Therefore, when the third motor is started, the upper traction rollers 17 rotate, and thus, in cooperation with the lower traction rollers 16, it can drive the polyethylene waste (waste drip irrigation tape) to move into the outer box body 1, achieving the effect of traction. A feed port 25 is provided on the corresponding outer box body 1.

[0024] Between the collection plate 2 and the outer box body 1, there is a drying component, and the drying component is connected to the outer box body 1. The drying component includes a drying pipe rack 13. The cross-section of the drying pipe rack 13 is in a U shape, and there are air outlet ports 14 provided on the inner side of the drying pipe rack 13. A number of air outlet ports 14 are evenly arranged. The working principle of the drying pipe rack 13 and the air outlet ports 14 is similar to that of the spray pipe rack 3. The drying pipe rack 13 is connected to the outer box body 1 through a bracket. A hot air blower 15 is installed on the outer box body 1, and the output end of the hot air blower 15 is connected to the drying pipe rack 13 through a pipe. Therefore, during operation, when the hot air blower 15 is started, the hot air blower conveys hot air into the drying pipe rack 13 through the pipe and finally sprays out from the air outlet ports 14, and then dries the washed polyethylene waste (waste drip irrigation tape). Steering rollers 26 are provided on the upper and lower sides of the drying pipe rack 13, which are responsible for the steering function.

[0025] Two groups of symmetrically arranged fixed plates 5 are installed in the outer box body 1, and the first crushing assembly and the second crushing assembly are arranged between the two groups of fixed plates 5 from top to bottom. A storage cavity 27 is formed on one side of the fixed plate 5 and the first crushing assembly, and a storage door 28 is installed on the front side of the outer box body 1, which can provide the function of storing items.

[0026] The specific first crushing component includes a shell 8, and the shell 8 is provided with two groups. The bottom end of the shell 8 is connected to the outer box body 1 through a bracket, and a first motor 9 is provided on the inner side of the shell 8. A cross cutter 10 is provided above the shell 8, and the lower end of the cross cutter 10 is connected to the output end of the first motor 9. The second crushing group includes two groups of symmetrically arranged crushing barrels 11. The surface of the crushing barrel 11 is provided with crushing teeth. The shaft of the crushing barrel 11 is connected to the outer box body 1 through a bearing. The shafts of the two groups of crushing barrels 11 are connected through a sprocket 12 and a chain. The crushing barrel 11 is driven by the second motor. Therefore, when working, the polyethylene waste (waste drip irrigation tape) enters the crushing interval after being cleaned and dried. In the process of falling, it will be collided and cut by the cross cutter 10 in a rotating state, and then further fall between the crushing barrels 11, such as Figure 1 As shown, a gathering hood 29 is provided above the crushing cylinder 11, and the gathering hood 29 plays the role of gathering and guiding the material to fall. The crushed polyethylene waste (waste drip irrigation tape) is further crushed by the crushing cylinder 11, and a collecting box 6 is provided below the corresponding second crushing component. A collecting port 7 is provided on one side of the collecting box 6 on the outer box body 1, so the crushed polyethylene waste (waste drip irrigation tape) enters the collecting box 6 to facilitate subsequent collection.

[0027] A guide assembly is provided above the first crushing assembly, and the guide assembly includes two groups of symmetrically arranged guide rollers 18. Both ends of the shafts of the two groups of guide rollers 18 are connected to the outer box body 1 through bearings. A blocking frame 19 is provided on one side of the guide roller 18, and the blocking frame 19 is fixedly connected to the outer box body 1. The polyethylene waste (waste drip irrigation tape) passes between the two groups of guide rollers 18. Since the polyethylene waste (waste drip irrigation tape) itself is elastic and bendable, it will fall downward after passing between the two groups of guide rollers 18 without support. The setting of the blocking frame 19 ensures that the position where the polyethylene waste (waste drip irrigation tape) falls is within a predetermined position, so that the polyethylene waste (waste drip irrigation tape) can better enter the crushing interval.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
