Description

Technical Field

[0001] This invention relates to the field of plastic film recycling devices, specifically a device for recycling torn plastic film used in tobacco seedling planting. Background Technology

[0002] Mulching tobacco seedlings during transplanting helps raise soil temperature, retain soil moisture, and reduce weed and pest damage. However, as the seedlings grow and the rainy season arrives, the mulch needs to be removed promptly to ensure a more suitable growing environment. Recycling the mulch is difficult and complicated, and with increasing years of mulching, the recycling rate of mulch residue in the soil is low, easily causing mulch pollution. Therefore, removing and recycling the mulch has become an essential part of tobacco seedling cultivation. However, there are few machines available for recycling mulch, and those that exist are large, complex, and costly. Mulch removal is mostly done manually, which is labor-intensive.

[0003] Existing mulch film recycling devices for tobacco seedling planting have certain drawbacks. First, traditional mulch film recycling devices cannot effectively tear the mulch film and cannot quickly shake off the soil covering the mulch film. Second, after the mulch film is rolled up, it is inconvenient to remove the film roll from the rolling roller. Third, traditional mulch film recycling devices cannot ensure that the mulch film is kept taut during the rolling process, which affects the rolling. Finally, traditional mulch film recycling devices cannot completely remove the side films, resulting in some mulch film residue. Therefore, a mulch film tearing and recycling device for tobacco seedling planting is proposed. Summary of the Invention

[0004] The problems that this invention aims to solve are: traditional mulch film recycling devices for tobacco seedling planting cannot effectively tear the mulch film, nor can they quickly shake off the soil covering the mulch film; traditional mulch film recycling devices for tobacco seedling planting are inconvenient to remove the film roll from the film rolling roller after the mulch film is rolled up; traditional mulch film recycling devices for tobacco seedling planting cannot ensure that the mulch film is in a taut state during the rolling process, which affects the rolling process; and traditional mulch film recycling devices for tobacco seedling planting cannot completely remove the side films buried in the soil, resulting in a certain amount of mulch film residue.

[0005] The objective of this invention can be achieved through the following technical solutions: A device for recycling torn mulch film used in tobacco seedling planting includes a support frame. Two rotating shafts are movably connected to the center of the support frame. A turntable is fixedly connected to one end of each of the two rotating shafts. A first connecting shaft is fixedly installed on one side of each of the two turntables. A connecting rod is movably connected to one end of each of the two first connecting shafts.

[0007] Furthermore, two film-collecting devices are fixedly installed on the bracket. The two film-collecting devices have the same structure and are arranged in a counter-support configuration. Each film-collecting device includes a mounting frame, and each film-collecting device is movably connected to a drive shaft. The drive shaft passes through the mounting frame, and a drive roller is arranged in the middle of the mounting frame. The drive shaft is fixedly inserted through the middle of the drive roller.

Counterweights are fixedly installed at both ends of the second tightening roller shaft. The diameter of the drive roller in the two film-forming devices is the same as that of the first tightening roller in the two tightening devices.

[0011] Furthermore, two drive shafts are movably inserted into the lower side of the bracket. A drive wheel is fixedly inserted into one end of each drive shaft, and a first bevel gear is fixedly inserted into the other end of each drive shaft. Support blocks are fixedly installed on both sides of the bracket, and gear shafts are movably inserted into the two support blocks. A second bevel gear is fixedly installed on each of the two gear shafts. A third bevel gear is fixedly installed at both ends of the transmission shaft.

[0013] Furthermore, two film-turning devices are fixedly installed on the support. The two film-turning devices have the same structure and are arranged in a counter-support configuration. Each film-turning device includes an adjusting plate, which is fixedly connected to the support. The adjusting plate has six adjusting screw holes, which are arranged in pairs.

A soil-turning plate is fixedly installed at the lower end of the telescopic rod. The soil-turning plate has an "L" shaped cross-section, and one end of the soil-turning plate is inclined downwards.

[0014] Furthermore, a connecting frame is fixedly installed on one side of the bracket, and four connecting columns are fixedly installed on the connecting frame. Two auxiliary wheel axles are fixedly installed on the lower side of the bracket, and an auxiliary wheel is movably inserted into one end of each of the two auxiliary wheel axles.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through its turntable, straight toothed plate, and arc toothed plate, solves the problems of traditional tobacco seedling planting mulch film recycling devices, which cannot effectively tear the mulch film and cannot quickly shake off the soil covering it. During use, several pointed cones mounted on the two dividing wheels will penetrate the mulch film upon contact, damaging the middle section. The two rotating shafts, when driven, rotate the two turntables fixedly connected to them. These turntables then rotate one end of two connecting rods via two first connecting shafts. Simultaneously, the other ends of the connecting rods drive two sliders via two second connecting shafts. Since the two sliders are movably inserted into two slide rails, their rotation is restricted by the turntables, thus promoting the movement of the two sliders. The slider moves back and forth on two slide rails. Since the two straight toothed plates and the two arc toothed plates are meshed, the two sliders drive the two straight toothed plates to move back and forth. At the same time, the two straight toothed plates can drive the two arc toothed plates to rotate repeatedly around the two intermediate shafts. Then, the two intermediate shafts drive the two swing rods, as well as the two swing roller shafts, two swing rollers and two return frames connected to one end of the two swing rods to rotate repeatedly. When the two halves of the mulch film pass between the two swing rollers and the two return frames of this device, the middle position of the mulch film can be damaged in advance by several sharp cones installed on the two dividing wheels. The repeated rotation of the two swing rollers and the two return frames can drive the two halves of the mulch film to tear continuously from the middle to both sides. In the process of tearing the mulch film, the two swing rollers and the two return frames can knock off the soil adhering to the mulch film.

[0016] 2. The film-receiving device solves the problem of traditional tobacco seedling planting mulch film recycling devices making it inconvenient to remove the film roll from the film-rolling roller after it has been rolled up. In use, after the film is rolled up, it needs to be removed from the two film-receiving devices separately. The two connecting bolts in the next film-receiving device need to be turned off, and the two stops need to be removed together. Then, the two arc-shaped plates are pulled. The two arc-shaped plates are restricted by the first hinge shaft, the second hinge shaft and the connecting plate, and will move into the installation groove. At the same time, the other side of the two arc-shaped plates will disengage from the center of the supporting mulch film roll, making the center of the mulch film roll loose. Then, the user can lift the mulch film roll appropriately and then remove the mulch film roll from one end of the film-rolling roller.

[0017] 3. The tightening device solves the problem of traditional tobacco seedling planting mulch film recycling devices failing to maintain tautness during winding, thus affecting the winding process. Since the transmission rollers in the two winding devices have the same diameter as the first tightening rollers in the two tightening devices, and the two gear shafts and two second sprockets are the same size, and the two first sprockets and two second sprockets are connected by two chains, they can rotate synchronously. Therefore, the speed at which the tightening device delivers the film to the winding device is the same as the speed at which the winding device winds the film. Furthermore, because the first tightening rollers in the two tightening devices cooperate to clamp the mulch film, the tightness of the mulch film between the ground and the tightening device will not affect the tightness of the mulch film between the winding device and the tightening device, thus avoiding any impact on the winding process.

[0018] 4. The film-turning device solves the problem of traditional tobacco seedling planting mulch film recycling devices being unable to completely remove the side films buried in the soil, resulting in some film residue. During use, the device is driven forward by a tractor. As the tractor moves forward, one end of the turning plates in the two film-turning devices will penetrate the soil, and as the tractor moves forward, the other end of the turning plates will bring the buried mulch film out of the ground, facilitating subsequent film recycling and preventing some film residue from polluting the soil. The adjustable holes and pins allow users to adjust the depth of the turning plates in the soil. By inserting the pins into different adjustment holes, the user can change the horizontal height of the telescopic rod and the turning plates, thus facilitating the turning of mulch film buried at different depths to the surface.

The two springs 26 are located between the movable plate 23 and the two limit blocks 27, respectively. Through the springs 26, due to the elasticity of the springs 26, a certain elastic force can be continuously provided to the movable plate 23.

[0036] A support shaft 24 is fixedly inserted into one side of the movable plate 23. A film roller 28 is movably inserted into the support shaft 24.

[0038] Please see Figure 5As shown, two tightening devices 3 are fixedly installed on the bracket 1. The two tightening devices 3 have the same structure and are arranged in a counter-support configuration. Each tightening device 3 includes two mounting plates 37, which are fixedly connected to the bracket 1. A first tightening roller shaft 39 is movably inserted into each mounting plate 37. A first tightening roller 41 is interactively inserted into the first tightening roller shaft 39 and is positioned between the two mounting plates 37.

The two first sprockets 63 and the two second sprockets 64 are the same size.

[0041] Please see Figure 6As shown, two film-turning devices 4 are fixedly installed on the support 1. The two film-turning devices 4 have the same structure and are arranged in a counter-support configuration. Each film-turning device 4 includes an adjusting plate 44, which is fixedly connected to the support 1. The adjusting plate 44 has six adjusting screw holes 45, which are arranged in pairs. An adjusting frame 46 is provided on one side of the adjusting plate 44, and four telescopic rods 47 are arranged in pairs on the adjusting frame 46. The distance between each pair of the three adjusting screw holes 45 is related to the distance between the two adjusting plates 44. The distance between the screw holes 45 is the same. Each of the four telescopic rods 47 is movably connected to a fixing bolt. The four fixing bolts are threadedly connected to the four adjusting screw holes 45. The second tightening roller shaft 40 is movably connected to the telescopic rod 47. Several adjusting holes 48 are opened on the telescopic rod 47. A pin 49 is movably connected to the adjusting frame 46. The pin 49 movably passes through one of the several adjusting holes 48. A soil turning plate 50 is fixedly installed at the lower end of the telescopic rod 47. The cross-section of the soil turning plate 50 is an "L" shaped structure, and one end of the soil turning plate 50 is inclined downward.

[0042] A connecting frame 67 is fixedly installed on one side of the bracket 1. Four connecting columns 68 are fixedly installed on the connecting frame 67. Two auxiliary wheel axles are fixedly installed on the lower side of the bracket 1. An auxiliary wheel 57 is movably inserted into one end of each of the two auxiliary wheel axles.

[0043] It should be noted that the present invention is a film tearing and recycling device for tobacco seedling planting. In use, firstly, the device is connected to the rear lifting mechanism of the tractor through the four connecting columns 68. Then, the tractor is driven to the tobacco seedling field ridge. Next, the user needs to operate the rear lifting mechanism of the tractor to lower the device to the ground. Then, the user needs to roll the film to be recycled into the device. The first step is for the user to cut the film in half in the middle. Then, the two halves of the film are passed between the two swing rollers 18 and the two loop frames 19 of the device. Next, the two second tightening rollers 42 are lifted respectively, and the two halves of the film are passed between the two first tightening rollers 41 and the two second tightening rollers 42 respectively. Then, the two halves of the film are wound around the film rolling rollers 28 of the two film taking devices 2 respectively. Then the user can drive the tractor forward. As the tractor moves forward, one end of the soil-turning plate 50 in the two soil-turning devices 4 will be driven into the soil. As the tractor moves forward, the soil-turning plate 50 buried in the soil will be brought out of the ground by the other end of the two soil-turning plates 50. This makes it easier to recycle the soil film in the next step and prevents some soil film from remaining in the soil and polluting the soil. At the same time, as the tractor moves forward, the two dividing wheels 54 set in this device will come into contact with the soil film and roll on the soil film. While the two dividing wheels 54 are rolling, one end of several sharp cones 55 installed on the two dividing wheels 54 will be driven into the soil film after contacting it, so as to damage the middle part of the soil film. Simultaneously, as the tractor moves forward, the two drive wheels 56 in contact with the ground rotate, which in turn drive the two first bevel gears 58 to rotate via the drive wheel shafts. Since the two second bevel gears 59 at both ends of the two gear shafts 62 are respectively meshed with the two first bevel gears 58 and the two third bevel gears 60, the two first bevel gears 58 can drive the two third bevel gears 60 to rotate via the two gear shafts 62 and the two second bevel gears 59 at both ends of the two gear shafts 62. Due to the transmission of the two second bevel gears 59 at both ends of the two gear shafts 62, the rotation directions of the two first bevel gears 58 and the two third bevel gears 60 are opposite. Then, the two third bevel gears 60 drive the transmission shaft 20 to rotate. The rotation of the two transmission shafts 20 can drive the transmission rollers 22 in the two film collection devices 2 to rotate. Then, the two transmission rollers 22 drive the two film winding rollers 28 and the film wound on the two film winding rollers 28 to rotate, causing the collected film to be wound on the two film winding rollers 28. Next, the rotation of the drive shaft 20 drives the two first sprockets 63 to rotate. Since the two first sprockets 63, the two second sprockets 64, and the two third sprockets 65 are connected by two chains 66, the rotation of the two first sprockets 63 can drive the two second sprockets 64 and the two third sprockets 65 to rotate through the two chains 66. The rotation of the two second sprockets 64 can drive the first tightening roller shafts 39 in the two tightening devices 3 to rotate. Since there is plastic film sandwiched between the first tightening rollers 41 and the second tightening rollers 42 in the two tightening devices 3, the rotation of the two first tightening roller shafts 39 can drive the two first tightening rollers 41 to rotate and convey the plastic film sandwiched between the first tightening rollers 41 and the second tightening rollers 42 in the two tightening devices 3 towards the two film collection devices 2. Simultaneously, the rotation of the two third sprockets 65 drives the rotation of the two rotating shafts 5, which in turn drive the rotation of the two turntables 6 fixedly connected to the two rotating shafts 5. Then, the two turntables 6 drive one end of the two connecting rods 9 to rotate via the two first connecting shafts 7. At the same time, the other ends of the two connecting rods 9 drive the movement of the two sliders 11 via the two second connecting shafts 8. Since the two sliders 11 are movably inserted into the two slide rails 10, their rotation is restricted by the two turntables 6, and they are prompted to reciprocate on the two slide rails 10. Because the two straight toothed plates 12 and the two arc toothed plates 13 are meshed, while the two sliders 11 drive the two straight toothed plates 12 to reciprocate, the two... A straight toothed plate 12 can drive two arc toothed plates 13 to rotate repeatedly around two intermediate shafts 14. Then, the two intermediate shafts 14 drive two swing rods 16, and the two swing roller shafts 17, two swing rollers 18 and two spiral frames 19 connected to one end of the two swing rods 16 to rotate repeatedly. Since the two halves of the mulch film pass through the two swing rollers 18 and the two spiral frames 19 of this device, the middle position of the mulch film can be damaged in advance by several sharp cones 55 installed on the two dividing wheels 54. The repeated rotation of the two swing rollers 18 and the two spiral frames 19 can drive the two halves of the mulch film to tear continuously from the middle to both sides. In the process of tearing the mulch film, the two swing rollers 18 and the two spiral frames 19 can knock off the soil adhering to the mulch film. After the film is wound up, the rolled-up mulch film needs to be removed from the two film winding devices 2. The two connecting bolts 35 in the next film winding device 2 need to be turned off, and the two stop bars 34 need to be removed together. Then, pull the two arc-shaped plates 33. The two arc-shaped plates 33, constrained by the first hinge shaft 30, the second hinge shaft 31, and the connecting plate 32, will move into the mounting groove 29. At the same time, the other side of the two arc-shaped plates 33 will disengage from the center supporting the mulch film roll, making the center of the mulch film roll loose. The user can then lift the mulch film roll appropriately and remove it from one end of the film winding roller 28. The user then reverses the above operation to restore the film winding device 2. The other film winding device 2 can be operated in the same way.
