Description

Technical Field

[0001] This utility model relates to a biodegradable membrane perforation and film collection device, belonging to the field of agricultural equipment technology. Background Technology

[0002] Biodegradable membranes are membrane materials that can be decomposed into harmless substances by microorganisms in the natural environment. In agriculture, biodegradable membranes can be used as agricultural mulch films, covering the soil surface to warm and retain moisture, and suppress weed growth. Compared to traditional plastic mulch films, biodegradable membranes can naturally degrade in the soil after use, avoiding pollution of the soil environment by mulch residue. However, to prevent seedlings from turning yellow when plants sprout, it is necessary to open holes in the biodegradable membrane in a timely manner.

[0003] Existing literature (publication number: CN 219190475 U) discloses a perforator for agricultural biodegradable films, which includes a perforating wheel, a threaded seat, and a perforator. This design, with its detachable structure of the perforator and threaded seat, allows for flexible adjustment and switching of the spacing between the perforators, expanding the applicability of the device and making it highly practical. Furthermore, the adjustable support assembly enables the perforator to smoothly perforate along the biodegradable film, thus improving the perforation quality. However, the existing design cannot promptly recover residual film after breaking the film, resulting in a large amount of biodegradable film remaining in the field, which is unsightly and unusable. In addition, the existing design easily pulls on the biodegradable film during breaking, causing damage or poor film opening quality. Utility Model Content

[0004] Based on the above, this utility model provides a biodegradable membrane perforation and collection device that can promptly recover the residual membrane generated by perforation, thereby overcoming the shortcomings of the prior art.

[0005] The technical solution of this utility model is: a biodegradable membrane perforation and collection device, comprising:

[0006] A perforation unit includes a rotating shaft, a perforating wheel rotatably mounted on the rotating shaft, a handrail frame mounted between the two ends of the rotating shaft, and perforators spaced circumferentially on the perforating wheel, wherein the perforators have membrane rupture openings;

[0007] The film collection unit includes an air nozzle installed inside the film breaking opening, an air pump installed on the perforating wheel, an air pipe connected to the air pump and the air nozzle, and a film collection box installed in the lower middle part of the rear side of the perforating wheel. The film collection box has a film collection opening facing the perforating wheel.

[0008] In one example, it also includes:

[0009] The film pressing unit includes a support frame mounted on a rotating shaft and film pressing wheels flexibly installed at the front and rear ends of the support frame.

[0010] In one example, the support frame includes an arc-shaped rod, a front crossbeam, and a rear crossbeam. The arc-shaped rod is installed on both sides of the pivot, and the front and rear crossbeams are installed at the front and rear ends of the arc-shaped rod, respectively.

[0011] The front and rear crossbeams are each equipped with vertically movable telescopic rods on both sides. The pressure roller is installed at the bottom of the telescopic rod, and a spring is sleeved on the telescopic rod.

[0012] In one example, a proximity sensor is mounted on the hole opener, and detection objects are mounted on the front and rear ends of the support frame corresponding to the proximity sensor.

[0013] In one example, the end of the membrane rupture opening is configured with an oblique shape.

[0014] In one example, the punching wheel has several threaded seats spaced circumferentially, and the puncher can be screwed onto the corresponding threaded seats.

[0015] In one example, the punching wheel is provided with a mounting base, and a plurality of the air pumps are mounted on the mounting base at circumferential intervals.

[0016] In one example, the air pump includes a miniature piston pump, a scroll pump, or a diaphragm pump.

[0017] The beneficial effects of this invention are as follows: With the designed film-collecting unit, when the perforator rotates to the bottom and breaks the film, an air pump draws in air, causing the broken film residue to be sucked into the tear opening. When it rotates to the film-collecting box, the air pump blows air, causing the residue in the tear opening to be blown into the film-collecting box for storage, avoiding the difficulty in collecting the residue. This improves the aesthetics and achieves resource recycling. Furthermore, the designed film-pressing unit can press down the film before and after the perforator, preventing the perforator from pulling on the biodegradable film, reducing tearing damage, and improving the perforation quality.

[0026] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] Please see Figures 1 to 4 This embodiment provides a biodegradable membrane perforation and collection device, which includes an perforation unit and a collection unit.

[0028] The perforation unit includes a rotating shaft 11, a perforating wheel 12, a handrail 13, and a perforator 14. The axial position of the perforating wheel 12 is mounted on the rotating shaft 11 through a bearing sleeve. The handrail 13 is installed between the two ends of the rotating shaft 11 to facilitate pushing the perforating wheel 12 to roll along the biodegradable membrane. The perforator 14 is installed circumferentially on the perforating wheel 12. The perforator 14 has a membrane-breaking opening. When the perforating wheel 12 rolls, the perforator 14 that rotates to the bottom contacts the biodegradable membrane and perforates the biodegradable membrane.

[0029] The film collection unit includes an air nozzle 21 installed inside the film-breaking opening, an air pump 22 installed on the perforating wheel 12, an air pipe 23 connected to the air pump 22 and the air nozzle 21, and a film collection box 24 installed in the lower middle part of the rear side of the perforating wheel 12. The film collection box 24 has a film collection opening facing the perforating wheel 12. When the perforator 14 rotates to the bottom, the air pump 22 draws in air, causing the broken film residue to be sucked into the film-breaking opening. When it rotates to the film collection box 24, the air pump 22 blows air, causing the film residue in the film-breaking opening to be blown into the film collection box 24 for storage, avoiding the difficulty in collecting the film residue, which improves the aesthetics and realizes the recycling of resources.

[0030] To improve the perforation effect, a pressure film unit is also included, which includes a support frame 31 mounted on the rotating shaft 11 and pressure film wheels 32 elastically installed at the front and rear ends of the support frame 31. Specifically, the support frame 31 includes an arc-shaped rod 311, a front crossbeam 312, and a rear crossbeam 313. The arc-shaped rod 311 is installed on both sides of the rotating shaft 11, and the front crossbeam 312 and the rear crossbeam 313 are installed at the front and rear ends of the arc-shaped rod 311, respectively. Vertically movable telescopic rods 33 are installed on both sides of the front crossbeam 312 and the rear crossbeam 313. The pressure film wheels 32 are installed at the bottom of the telescopic rods 33, and springs 34 are sleeved on the telescopic rods 33. Thus, on the one hand, the perforating wheel 12 can be made to travel straight with the help of the support frame 31 and the pressure film wheels 32, and on the other hand, the pressure film wheels 32 press down the membrane in front and behind the perforator 14, which can prevent the perforator 14 from pulling the biodegradable membrane and reduce the tearing damage of the biodegradable membrane.

[0031] For ease of operation, a proximity sensor 25 is installed on the perforator 14, and detection objects 26 are installed at the front and rear ends of the support frame 31 corresponding to the proximity sensor 25. For example, a magnetic proximity sensor 25 is selected as the proximity sensor 25, and the detection object 26 is a magnet. Thus, with two magnets at the front and rear, when the proximity sensor 25 on the perforator 14 senses the front magnet, it controls the air pump 22 to draw in air (or draw in air after a few seconds) to hold the residual film into the film breaking opening; when the proximity sensor 25 on the perforator 14 senses the rear magnet, it controls the air pump 22 to blow air (or blow air after a few seconds) to blow the residual film in the film breaking opening into the film receiving box 24. It should be noted that it can be set to a reciprocating action of drawing in and blowing air, that is, when a detection object 26 is sensed, the air pump 22 draws in air, and when the next detection object 26 is sensed, the air pump 22 blows air.

[0032] For ease of operation, the end of the membrane puncture opening is designed with an angled shape, which facilitates quick puncture and cutting of the biodegradable membrane.

[0033] For ease of operation, the punching wheel 12 has several threaded seats 15 spaced apart along its circumference. The hole opener 14 can be screwed onto the corresponding threaded seats 15. Each threaded seat 15 is pre-installed with an air nozzle 21, so that the position of the hole opener 14 can be quickly adjusted according to the hole opening distance.

[0034] For ease of installation, the punching wheel 12 is equipped with a mounting base 27, on which multiple air pumps 22 are installed at circumferential intervals. The air pumps 22 can be miniature piston pumps, or vortex pumps, diaphragm pumps, or other pumps capable of both suction and blowing air.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
