Description

Technical Field

[0001] The present invention relates to the field of ground film recovery, and in particular to a drum-type high-strength film recovery device. Background Art

[0002] For some special crops, during the planting process, the land surface needs to be covered with high-strength film that is stronger than other ground films to help the crops grow smoothly. This high-strength film is for one-time use and needs to be recycled after the crops grow and are harvested. The high-strength film that has been left for a long time may become residual film due to the influence of external factors, while the high-strength film that has been left for a short time still maintains a nearly complete film body as it was when it was laid. During the recovery process of the high-strength film in the latter case, the existing recovery device cannot hook up the high-strength and complete high-strength film at one time due to the influence of the strength. As a result, after the device has been run once, the high-strength film on the soil surface is not completely recovered and needs to be reworked for a second recovery.

[0003] Therefore, a drum-type high-strength film recovery device is needed to solve the above technical problems. Summary of the Invention

[0035] See also Figure 1-Figure 5 The present invention provides a drum-type high-strength film recovery device, comprising:

[0036] A vehicle body 1 on which a processing drum 2 is provided;

[0037] The conveying path 3 is provided at the front end of the vehicle body 1 and is connected to the processing drum 2;

[0038] A fixing frame 4 is connected to an end of the conveying path 3 away from the vehicle body 1;

[0039] A swing arm 5, one end of which is rotatably connected to the fixing frame 4, and the other end of which is rotatably connected to a pleating assembly 6;

[0040] a membrane lifting plate 7, arranged at the front end position below the fixing frame 4; and

[0041] The hook film assembly 8 is rotatably arranged at the rear end position below the fixing frame 4.

[0042] In this embodiment, the film lifting plate 7 shovels up the high-strength film covering the ground surface, and the pleating component 6 pre-pleats the surface of the high-strength film below so that it can be hooked up and recycled at one time. As the vehicle body 1 continues to move forward, the high-strength film after pleating will be brought to the bottom of the film hooking component 8 and hooked up by it, and finally transported through the conveyor belt 3 into the processing drum 2 for subsequent processing.

[0043] Furthermore, the pleating assembly 6 includes:

[0044] The roller 61 is rotatably mounted on the swing arm 5;

[0045] The support rod 62 is circumferentially arranged on the outer wall of the roller 61;

[0046] A connecting rod 63, one end of which is fixedly connected to the support rod 62 and the other end of which is rotatably connected to the pleating rod 64; and

[0047] The spring 65 is connected between the inner side surfaces of the connecting rod 63 and the pleating rod 64 through a fixing seat.

[0048] Furthermore, eight groups of plucking contacts 641 are equidistantly fixedly connected to a side of the plucking rod 64 opposite to the fixed seat. Each group of the plucking contacts 641 consists of a base and a plucking ball. The plucking ball is cooperatively connected to the base, and the surface of the plucking ball is frosted particles with a high-hardness rough material.

[0049] As a preferred embodiment, the roller 61 rotates with the help of the support rod 62 to drive the connecting rod 63. During the rotation, when the plucking rod 64 does not contact the high-strength film below, the spring 65 is in a natural state. When the plucking rod 64 begins to contact the high-strength film below, due to the high strength of the high-strength film, the plucking rod 64 will start to rotate and compress the spring 65. With the help of the elastic force of the spring 65, the plucking ball will have a downward push-out tendency. In other words, the friction between the plucking ball and the high-strength film will increase, that is, the frosted particles of the high-hardness and rough material on the surface of the plucking ball will cause the smooth high-strength film surface to rub and wrinkle, achieving the effect of pre-pleating treatment, so that it can be hooked up and recycled at one time later to avoid residue and rework for secondary recycling.

[0050] Furthermore, the film-lifting plate 7 includes: a plate body 71, which is arranged at the front end position below the fixing frame 4, and film-lifting heads 72 are equidistantly arranged on the plate body 71 through a connecting seat, and a film-lifting tip 73 is connected to the end of the film-lifting head 72 away from the plate body 71.

[0051] Furthermore, a support block 721 is fixed to one end of the film-forming head 72 close to the connecting seat, and a through groove 722 is provided on the film-forming head 72 between the film-forming tip 73 and the support block 721. The top of the film-forming tip 73 is streamlined, and its vertical height is consistent with that of the support block 721.

[0052] In this embodiment, the film-lifting head 72 can scoop up the high-strength film with a complete film body by means of the streamlined design of the film-lifting tip 73. Since the film-lifting tip 73 and the support block 721 are vertically aligned, with the help of the subsequent film hook assembly 8 to pull the high-strength film, the high-strength film will be tightly attached to the streamlined back of the film-lifting tip 73 and the top surface of the support block 721. A through groove 722 is provided below the high-strength film between the film-lifting tip 73 and the support block 721, so that the high-strength film has a space to be recessed downward (such as Figure 4 As shown), it helps the above-mentioned puckers to pre-pleat the surface of the high-strength film.

[0053] Furthermore, the film hook component 8 includes:

[0054] The rotating shaft 81 is rotatably arranged at the rear end position below the fixing frame 4;

[0055] The annular plates 82 are configured into two groups, and the two groups of annular plates 82 are connected to the two ends of the rotating shaft 81 through connecting frames respectively;

[0056] The arc-shaped plate 83 is disposed between the two groups of the annular plates 82, and multiple groups are arranged along the circumference of the annular plates 82;

[0057] A mounting hole 84 is provided between two adjacent arc-shaped plates 83 and located on the annular plate 82; and

[0058] The central shaft is fixedly installed in the mounting holes 84 corresponding to the two sets of annular plates 82, and the central shaft is provided with sliding cavities 85 that are equidistantly rotated along the axial direction. A film-hooking knife 86 is slidably connected in the sliding cavity 85, and the film-hooking knife 86 is connected to the inside of the sliding cavity 85 through an auxiliary spring 87.

[0059] Furthermore, the annular plate 82 is connected to a transverse plate 9, and the transverse plate 9 is connected to a support portion 88. A baffle 89 is provided between the support portion 88 and the transverse plate 9. One end of the baffle 89 is designed as a tip that cooperates with the blade head of the film-hooking knife 86, and the other end is designed as a 45° chamfer.

[0060] Furthermore, a torsion spring is built into the rotational connection between the sliding cavity 85 and the central axis, and the torsion spring is a high-torsion force type torsion spring.

[0061] As a preferred embodiment, the high-strength film after the pre-pleating process will be brought to the bottom of the film hooking assembly 8, and the film hooking operation will be completed first. Figure 5 The details are as follows: the rotating shaft 81 drives the film-hooking knife 86 to rotate around the axis of the rotating shaft 81 with the help of the central axis. When the film-hooking knife 86 is in position ①, its knife head will conflict with the lower baffle 89. As the rotating shaft 81 rotates, the film-hooking knife 86 moves to position ②. With the help of the torsion spring and the limiting effect of the knife head on the baffle 89, the film-hooking knife 86 will twist an angle and maintain this angle to continue rotating forward. When the film-hooking knife 86 moves to position ③, the knife head is out of contact with the baffle 89. Under the reset action of the torsion spring, it will quickly insert into the high-strength film below and hook it, and then drive the high-strength film to continue moving. It should be noted that when the film-hooking knife 86 hooks up the high-strength film, its internal torsion spring will not rotate.

[0062] Next, complete the film removal operation. Figure 5 , specifically as follows: the film hooking knife 86 at position ④ is in the same state as the film hooking knife 86 at position ①, the film hooking knife 86 at position ⑤ is in the same state as the film hooking knife 86 at position ②, and the film hooking knife 86 at position ⑥ is in the same state as the film hooking knife 86 at position ③. Unlike position ③, the film hooking knife 86 at position ⑥ throws out the hooked high-strength film under the resetting action of the torsion spring, and makes it enter the conveying path 3 and be conveyed to the processing drum 2 for subsequent processing. Due to the high torsional force setting of the torsion spring, the above-mentioned film hooking operation can ensure that the high-strength film that has been pre-pleated can be hooked up at one time, without being affected by its strength, and is fully recycled to prevent secondary rework. The above-mentioned film unloading operation can reach a certain force to completely throw out the high-strength film without any residual residue.

[0063] It should be noted that the rotation speed of the hook membrane assembly 8 is 10%-20% faster than the forward speed of the vehicle body 1, so as to better recover the high-strength membrane.

[0064] During specific implementation, the vehicle body 1 starts to move forward, the film-lifting plate 7 scoops up the high-strength film covering the ground surface, and the pleating component 6 pre-pleats the surface of the high-strength film below so that it can be hooked up and recycled at one time. As the vehicle body 1 continues to move forward, the pleated high-strength film will be brought to the bottom of the film hooking component 8 and hooked up by it, and finally transported through the conveyor 3 into the processing drum 2 for subsequent processing.

[0065] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
