Description

Technical Field

[0001] The invention relates to the field of agricultural film processing, and in particular to a feeding device for recycling waste agricultural films and a use method thereof. Background Art

[0002] With the increasing application and service life of agricultural films, the white pollution caused by a large amount of residual agricultural films has also seriously affected agricultural production. Therefore, it is necessary to process the plastic agricultural films, and then feed the agricultural films into the pellet machine for melting and plasticizing into plastic pellets. Before melting, it is generally necessary to perform some crushing. However, the current crushing mechanism drives the blades to crush the plastic through the rotating shaft. There is a certain distance between the blades. However, when the agricultural films are crushed, the agricultural films are loose and soft and easy to stretch. On the one hand, the crushing effect is not good enough. On the other hand, the friction of the agricultural films in a loose state is more likely to produce electrostatic adsorption, which is easy to cause adsorption between the agricultural films and the defects of winding on the rotating shaft, which can easily cause damage to the equipment. Summary of the invention

A drive motor is provided on one side of one of the support plates, and the output end of the drive motor rotates through the support plate and is connected to the screw.

[0009] Specifically, a shielding strip is slidably embedded in the inner wall of one side between the two first sliding holes, one end of the shielding strip inserted into the inner wall of the first sliding hole is connected with a second spring, and the two inner walls of the second sliding holes are connected with rubber strips.

[0010] Preferably, a first push switch and a second push switch are fixedly provided on the outer side of one of the sliding columns, and the first push switch and the second push switch can respectively abut against the lifting plate.

[0015] The extrusion plate is pressed downward by the driving component of the lifting and squeezing component to squeeze the waste agricultural film, so that the waste agricultural film is more compact. When the extrusion plate moves to the bottom of the upper barrel, the driving component automatically moves to the top of the upper barrel to continue squeezing the newly placed waste agricultural film.

[0016] At the same time, the driving component 2 of the crushing component is used to rotate the crushing blade to crush the waste agricultural film, and the guide plate is rotated in the opposite direction to discharge the crushed waste agricultural film.

[0017] The advantages of the present invention compared with the prior art are:

[0018] 1. During the process of crushing the waste plastic agricultural film, the agricultural film is squeezed to change the film from a loose state to a tight state. On the one hand, the crushing blade can more effectively grasp and cut the plastic film during crushing. At the same time, the shape of the plastic agricultural film after extrusion is more regular and uniform, and the crushing blade can cut the waste agricultural film more evenly, reducing the situation of insufficient crushing of the agricultural film. On the other hand, by pressing the waste agricultural films tightly, the electrostatic adsorption effect between the waste agricultural films is reduced. The above scheme achieves the purpose of increasing the crushing effect to reduce the incomplete crushing of the waste agricultural film and the entanglement of the waste agricultural film caused by electrostatic adsorption.

[0019] 2. Through the action of the lifting and extrusion components, the automatic reciprocating lifting and lowering is realized. After the waste agricultural film is crushed, the extrusion plate is automatically moved out from the bottom of the upper barrel, and automatically moved to the top of the upper barrel for extrusion again, which improves the degree of automation to a certain extent;

[0020] 3. When the rotating rod slides in the second sliding hole, the second sliding hole except the rotating rod position is always closed by the rubber strip. In addition, when the extrusion plate needs to slide out of the first sliding hole, the elastic force of the second spring is first overcome to squeeze the shielding strip and automatically open the first sliding hole. When the shielding strip slides out of the first sliding hole, the shielding strip is closed again by the elastic force of the second spring, thereby preventing the waste film from running out of the loading barrel through the first sliding hole and the second sliding hole;

[0021] 4. Through the action of the crushing component, the bottom of the waste agricultural film after extrusion is crushed by the action of the crushing blade, and at the same time, the guide plate rotates in the opposite direction. On the one hand, the guide bar rotates to push the crushed agricultural film into the discharge cover for discharge (through the dual action of the arc-shaped inclined guide bar and centrifugal force). On the other hand, the waste agricultural film that has been crushed to the bottom is cleaned to avoid blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] See also Figure 1 , Figure 2 , Figure 4 , and also proposes a method for using a feeding device for recycling waste agricultural film, including:

[0052] Place the agricultural film to be loaded on the upper end of the loading barrel 1;

[0053] The driving component 1-4 of the lifting and squeezing component 2 is used to squeeze the waste agricultural film downward to make the waste agricultural film more compact. When the squeezing plate 3 moves to the bottom of the upper barrel 1, the driving component 1-4 automatically moves to the top of the upper barrel 1 to continue squeezing the newly placed waste agricultural film.

[0054] At the same time, the driving assembly 2 6 of the crushing assembly 5 is used to rotate the crushing blade 7 to crush the waste agricultural film, and the guide plate 8 is rotated in the opposite direction to discharge the crushed waste agricultural film.

[0055] In some specific embodiments, the upper end of the loading barrel 1 is connected to a feeding hopper 44 to facilitate the placement of more waste agricultural films.

[0056] In some specific embodiments, a controller (not shown in the figure) electrically connected to the electromagnet 23 , the driving motor 1 25 , the driving motor 2 33 , the first push switch 29 and the second push switch 30 is also included.

[0057] In some specific embodiments, a pressure sensor 46 connected to a controller is provided on the bottom side of the extrusion plate 3. During specific implementation, the size of the pressure sensor 46 can be adjusted according to demand.

[0058] The working principle and use process of the present invention:

[0059] In Example 1, the agricultural film to be broken is placed in the upper barrel 1 through the feed hopper 44, and the rotation of the driving motor 25 is turned on to drive the screw 24 (reciprocating screw) to rotate, and the reciprocating slider 45 drives the lifting plate 11 to reciprocate and stably lift and lower on the outside of the sliding column 10. When the lifting plate 11 moves to the bottom of the upper barrel 1, it is squeezed with the second push switch 30 on the sliding column 10, and the generated electrical signal is transmitted to the controller, and the electromagnet 23 is automatically turned on by the controller to attract the permanent magnet 22, so that the slide bar 20 slides quickly through the fixed plate 19, and the rotation of the rotating tube 17 is driven by the rotating plate 18, and the extrusion plate 3 is automatically moved out of the first sliding hole 13 in cooperation with the rotating rod 12. At this time, the lifting plate 11 keeps moving downward at a relatively slow speed, and the rigid contact between the components is overcome by the deformation of the rubber pad 42 to cause damage to the equipment. When the extrusion plate 3 moves out of the first sliding hole 13, The lifting plate 11 is driven to start moving up by the action of the reciprocating screw 24 and the reciprocating slider 45 until the lifting plate 11 and the first push switch 29 are against each other, and the generated electrical signal is transmitted to the controller, and the electromagnet 23 is automatically turned off by the controller to no longer attract the permanent magnet 22, and the permanent magnet 22 and the rotating plate 18 are automatically reset by the elastic force of the spring 1 43. When the rotating plate 18 rotates, the lifting plate 11 will continue to move up slowly, and the rigid contact between the components is overcome by the deformation of the rubber pad 42 to overcome the damage to the equipment caused by the rigid contact between the components, so that the rotating tube 17 is rotated and reset, and the extrusion plate 3 is automatically driven to rotate through the first sliding hole 13 at the top of the upper barrel 1 through the rotating rod 12 to enter the upper barrel 1. At this time, the lifting plate 11 starts to move down again, and the rotating rod 12 slides downward in the second sliding hole 14 at the same time, and the lifting plate 11 squeezes the waste agricultural film in the upper barrel 1, so that the agricultural film changes from a loose state to a tight state;

[0060] By turning on the rotation of the second driving motor 33, the gear 41 is driven to rotate, and the ring gear 1 34 is cooperated to drive the rotating shaft 39 to rotate, and the ring gear 2 35 is cooperated to drive the rotating tube 2 38 to rotate in the opposite direction relative to the rotating shaft 39, thereby driving the guide plate 8 to rotate, and the bottom of the waste agricultural film after extrusion is crushed by the action of the crushing blade 7. At the same time, the guide plate 8 rotates in the opposite direction. On the one hand, the guide bar 32 is rotated to push the crushed agricultural film into the discharge cover 31 for discharge (under the dual action of the arc-shaped inclined guide bar 32 and the centrifugal force), and on the other hand, the guide bar 32 cleans the waste agricultural film that has been crushed at the bottom of the crushing blade 7 to avoid clogging;

[0061] During the process of crushing the waste agricultural film, when the lifting plate 11 moves to the bottom of the upper barrel 1, it is squeezed by the second push switch 30 on the sliding column 10. Through the above scheme, the squeezing plate moves out of the upper barrel and stops processing the waste agricultural film until the squeezing plate moves to the top of the upper barrel to continue squeezing the newly placed waste agricultural film.

[0062] In Example 2, through the action of the pressure sensor 46, when the extrusion plate 3 is pressed down, the pressure value of the waste agricultural film squeezed by the pressure sensor 46 is transmitted to the controller, and a certain threshold is set in the controller. When the pressure value detected by the pressure sensor 46 is greater than the threshold, it means that the waste agricultural film is squeezed to a certain extent, and then the controller automatically turns on the drive motor 2 33 to start crushing the waste agricultural film. When the extrusion plate 3 reaches the bottom of the loading barrel 1 and is squeezed by the second press switch 30 on the sliding column 10, the generated electrical signal is transmitted to the controller, and the electromagnet 23 is turned on while the drive motor 2 33 is turned off to stop the crushing work until the waste agricultural film is squeezed again and then crushed, thereby improving the effect of crushing the agricultural film.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art.
