Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a roll-up combined residual plastic film recycling machine. Background Technology

[0002] Mulching technology has been widely used in the cultivation of crops such as corn, cotton, peanuts, vegetables, and tobacco, significantly increasing crop yields. However, if the mulch film is not recycled in a timely manner, it will affect the transport of water, air, and fertilizer in the soil, as well as microbial activity, leading to a deterioration in soil physical properties and thus impacting crop yields. Manual mulch film recycling is labor-intensive and inefficient. While machine-made mulch film recycling systems can recover mulch film from the soil, making them suitable for resource utilization applications requiring high impurity levels, existing systems are prone to missing fragments of film, resulting in low soil cleanliness.

[0003] To address this, a roll-up combined residual plastic film recycling machine is proposed, which can collect whole films and broken films in one pass, thereby increasing the soil cleanliness rate. At the same time, it is convenient to classify whole films and broken films according to their impurity content for resource utilization. Summary of the Invention

[0018] Preferably, the film recycling mechanism includes a recycling main frame located at the end of the film roll sleeve away from the film lifting assembly. The middle part of the recycling main frame is hinged to the frame, and the bottom of the recycling main frame is hinged to the frame via a telescopic connecting rod.

The film-soil separation component separates the soil mixed in with the film, and then transfers the entire film to the film-winding roller sleeve. The transmission mechanism drives the telescopic teeth to extend out of the tooth holes, causing the telescopic teeth to protrude outside the film-winding roller sleeve. Simultaneously, the transmission mechanism drives the film-winding roller sleeve to rotate, so that when the entire film passes through the film-winding roller sleeve, the telescopic teeth can hook the entire film, causing the entire film to automatically wind up onto the film-winding roller sleeve as the sleeve rotates. The wound film has a low impurity content, making it suitable for resource utilization applications with strict requirements on impurity content. Simultaneously, the film fragment recovery mechanism enters the soil to pick up residual film fragments, automatically recovering them and improving the soil cleanliness rate. When the wound film needs to be unloaded, the transmission mechanism drives the telescopic teeth to retract into the tooth holes, releasing the hook from the film. Then, the unloading mechanism drives the film-winding roller sleeve to move, smoothly completing the automatic unloading. The height of the machine off the ground can be controlled by controlling the walking and lifting mechanism. This invention can automatically recycle whole and broken plastic film in the soil at the same time, reducing the impurity content of the whole film, increasing the recycling rate of plastic film, reducing the residue of plastic film in the soil, and automatically unloading the film after the whole film is recycled. It has a high degree of automation and reduces the amount of manual work. Attached Figure Description

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] Reference Figure 1 and Figure 6-8 This invention provides a roll-up combined residual plastic film recycling machine, comprising:

[0047] The frame 1 has a walking and lifting mechanism installed at its bottom and a transmission mechanism installed on its top.

[0048] The film-forming mechanism includes a film-forming component 4 and a film-soil separation component 9 mounted on the frame 1. The discharge end of the film-forming component 4 is connected to the inlet end of the film-soil separation component 9.

[0049] The film winding mechanism includes several film winding roller sleeves 15-2 mounted on the frame 1. The film winding roller sleeves 15-2 are located at the bottom of the discharge end of the film-soil separation component 9. Several toothed holes 15-2-1 are circumferentially opened on the side wall of the film winding roller sleeves 15-2. Several telescopic teeth 15-3-1 are installed inside the film winding roller sleeves 15-2 through a connecting component. The transmission mechanism is used to drive the several telescopic teeth 15-3-1 to extend or retract the several toothed holes 15-2-1 respectively.

[0050] The film unloading mechanism 14 is installed on the frame 1 and is used to drive the film roll sleeve 15-2 to automatically unload the film;

[0051] The film breakage recovery mechanism 11 is installed on the frame 1 and located at the end of the film roll sleeve 15-2 away from the film lifting assembly 4. The film breakage recovery mechanism is used to enter the soil to grab and recover the broken film.

[0052] The membrane-soil separation component 9, the broken membrane recycling mechanism 11, and several membrane roll sleeves 15-2 are all connected to the transmission mechanism.

[0053] The film lifting component 4 lifts the entire film from the soil and passes it to the film-soil separation component 9. The film-soil separation component 9 initially separates the soil mixed in with the film, and then passes the entire film to the film winding roller sleeve 15-2. The transmission mechanism drives the telescopic tooth 15-3-1 to extend out of the tooth hole 15-2-1, so that the telescopic tooth 15-3-1 protrudes outside the film winding roller sleeve 15-2. At the same time, the transmission mechanism drives the film winding roller sleeve 15-2 to rotate, so that the telescopic tooth 15-3-1 can hook the film as it passes through the film winding roller sleeve 15-2. The film is automatically wound onto the film-winding roller sleeve 15-2 as the film-winding roller sleeve rotates. Simultaneously, the film fragment recovery mechanism 11 enters the soil to collect any remaining film fragments, automatically recovering them. When the wound film needs to be unloaded, the traveling lifting mechanism is controlled to lift all the machine's soil-entry components off the ground. The transmission mechanism drives the telescopic teeth 15-3-1 to retract into the tooth holes 15-2-1, releasing the film from its hook. Then, the unloading mechanism 14 drives the film-winding roller sleeve 15-2 to move, smoothly completing the automatic unloading. This invention can automatically recover both whole and broken film fragments from the soil simultaneously, improving the film recovery efficiency, reducing film residue in the soil, and automatically unloading the film after recovery. It boasts a high degree of automation, reducing manual labor.

[0054] like Figure 6-10 As shown, in a further optimized scheme, several rows of toothed holes 15-2-1 are arranged along the axial direction of the film roll sleeve 15-2;

[0055] The connecting assembly includes a film roller shaft 15-5 rotatably connected inside the film roller sleeve 15-2. The side wall of the film roller shaft 15-5 is hinged with a number of telescopic teeth 15-3-1. The telescopic teeth 15-3-1 are respectively arranged in a one-to-one correspondence with a number of tooth holes 15-2-1. The end of the telescopic teeth 15-3-1 away from the film roller shaft 15-5 is slidably connected to the inner side wall of the film roller sleeve 15-2 and the tooth holes 15-2-1. A number of long strip baffles 15-2-2 are fixedly connected to the inner side wall of the film roller sleeve 15-2. The long strip baffles 15-2-2 are respectively located on one side of a number of tooth holes 15-2-1 in each row. The film roller shaft 15-5 is connected to the transmission mechanism.

[0056] The film roll sleeve 15-2 and the film roll shaft 15-5 together constitute the film roll 15. One end of the film roll sleeve 15-2 is fixed with an end cap 15-1, and the other end is fixed with a sprocket 15-4. The telescopic holes 15-2-1 are arranged in three rows. Several spacer sleeves 15-3-2 are fixedly connected to the film roll shaft 15-5. Parallel discs 15-3-3 are fixedly connected to both ends of the spacer sleeves 15-3-2. The parallel discs 15-3-3 are fixedly connected to the film roll shaft 15-5. Several pins are installed on the two parallel discs 15-3-3. One end of the telescopic tooth 15-3-1 is hinged to the pin.

[0057] like Figure 2 , Figure 9-11 As shown, in a further optimized scheme, a film unloading frame 14-3 is installed on the frame 1, and one end of the film winding roller shaft 15-5 extends out of the film winding roller sleeve 15-2 and is rotatably connected to the film unloading frame 14-3. There are two film winding roller sleeves 15-2.

[0058] The first guide tube 1-8 and the second guide tube 1-10 are fixedly connected to the frame 1, and the film unloading frame 14-3 is slidably connected to both the first guide tube 1-8 and the second guide tube 1-10.

[0059] The transmission mechanism includes a first transmission assembly mounted on the frame 1 and a second transmission assembly mounted on the film unloading frame 14-3. A first sprocket 23 is drivenly connected to the first transmission assembly, and the input shaft of a clutch 22 is drivenly connected to the first sprocket 23. A double-row sprocket 19 and a fourth sprocket 20 are drivenly connected to the output shaft of the clutch 22. The double-row sprocket 19 and the fourth sprocket 20 are respectively fixedly connected to one end of the two film roll shafts 15-5. The first sprocket 23 is rotatably connected to the outer wall of the frame 1, and the double-row sprocket 19 and the fourth sprocket 20 are both rotatably connected to the film unloading frame 14-3.

[0060] The membrane-soil separation component and the broken membrane recycling mechanism are both connected to the first transmission component, and the two membrane roller sleeves 15-2 are connected to the second transmission component.

[0061] The first sprocket 23 is connected to the second sprocket via a first chain drive. The input shaft of the clutch 22 is fixedly connected to the second sprocket. The output shaft of the clutch 22 is fixedly connected to the third sprocket 21. The third sprocket 21 is connected to a double-row sprocket 19 via a second chain drive. The double-row sprocket 19 is connected to a fourth sprocket 20 via a third chain drive. The third sprocket 21 is rotatably connected to the unloading frame.

[0062] Before film winding, the telescopic tooth 15-3-1 does not extend out of the tooth hole 15-2-1. When film winding is required, the first transmission component drives the first sprocket 23 to rotate. The first sprocket 23 drives the clutch 22 to rotate. The clutch 22 drives the double-row sprocket 19 and the fourth sprocket 20 to rotate simultaneously, causing the two film winding roller shafts 15-5 to rotate. The film winding roller shafts 15-5 drive the disc body 15-3-3 to rotate. The telescopic tooth 15-3-1 extends out of the telescopic hole 15-2-1 under the obstruction of the long strip baffle 15-2-2. At the same time, the disc body 15-3-3 drives the film winding roller sleeve 15-2 to rotate, thus forming the film mounting assembly 15-3 (e.g., ...). Figure 9 As shown in the figure, the plastic film can be hung up for rolling up.

[0063] like Figure 1 , Figure 2 , Figure 6 , Figure 11As shown, in a further optimized scheme, the second transmission component includes a hydraulic motor 14-4 fixedly connected to the film unloading frame 14-3, a fifth sprocket 24 fixedly connected to the output shaft of the hydraulic motor 14-4, the fifth sprocket 24 being rotatably connected to the film unloading frame 14-3, and a sixth sprocket 15-4 fixedly connected to one side of the outer wall of the film roll sleeve 15-2, the fifth sprocket 24 being connected to the two sixth sprockets 15-4 through a fourth chain;

[0064] The film unloading mechanism includes a first automatic film unloading hydraulic cylinder 14-1 and a second automatic film unloading hydraulic cylinder 14-2 fixedly connected to the frame 1. The piston rods of the first automatic film unloading hydraulic cylinder 14-1 and the second automatic film unloading hydraulic cylinder 14-2 are both fixedly connected to the film unloading frame 14-3. Two film unloading channels 1-12 are opened on the side wall of the frame 1. One end of the film roll sleeve 15-2 near the film unloading frame 14-3 extends out of the film unloading channel 1-12 and is fixedly connected to... The sixth sprocket 15-4 and the two film roll sleeves 15-2 are slidably connected to the two film unloading channels 1-12 respectively. Wear-resistant elastic rubber rings are fixedly connected to the inner side of the film unloading channels 1-12. The wear-resistant elastic rubber rings are coaxial with the film unloading channels 1-12 and are interference-fitted with the outer wall of the film roll sleeves 15-2. Under the action of the wear-resistant elastic rubber rings, the film roll sleeves 15-2 can easily drop the whole film from the film roll sleeves 15-2 when passing through the film unloading channels 1-12.

[0065] During film unloading, the traveling lifting mechanism is controlled to lift all the machine's soil-entry parts off the ground, stopping the film-rewinding operation. The hydraulic motor 14-4 is then started, driving the fifth sprocket 24 to rotate. The fifth sprocket 24 then drives the two sixth sprockets 15-4 to rotate, which in turn drives the film-winding roller 15-2 to rotate (in the same direction as during film winding). The film-winding roller 15-2 rotates a certain angle, causing the telescopic teeth 15-3-1 to retract into the telescopic hole 15-2-1. This, through the long baffle 15-2-2, drives the disc 15-3-3 to rotate, which in turn drives the entire film-winding roller shaft 15-5 to rotate (at this point, the state is as follows). Figure 10 (As shown); then, the piston rods of the first automatic film unloading hydraulic cylinder 14-1 and the second automatic film unloading hydraulic cylinder 14-2 are controlled to move outward, causing the film unloading frame 14-3 to move away from the machine frame 1, causing the input shaft and output shaft of the clutch 21 to partially disengage, and at the same time causing the film roll sleeve 15-2 to move outward, thereby causing the film roll sleeve 15-2 to move outward along the film unloading channel 1-12, and the film wrapped on the film roll sleeve 15-2 falls off under the obstruction of the side plate of the machine frame, and is picked up manually before the machine continues to operate.

[0066] like Figure 1 , Figure 14As shown, in a further optimized scheme, the film recycling mechanism 11 includes a recycling main frame 11-3 located at the end of the film roll sleeve 15-2 away from the film lifting assembly. The middle part of the recycling main frame 11-3 is hinged to the frame 1 via a hinge connection 12, and the bottom of the recycling main frame 11-3 is hinged to the frame 1 via a telescopic connecting rod 13. Two rear depth limiting wheels 11-1 are rotatably connected to the bottom of the recycling main frame 11-3. A first sprocket shaft 11-7 and a second sprocket shaft 11-7 are rotatably connected to the recycling main frame 11-3. The first sprocket shaft 11-7 is connected to the first transmission assembly. The first sprocket shaft 11-7 is connected to the second sprocket shaft 11-13 through two fifth chains 11-9. Several spring tooth fixing rods 11-10 are fixed between the two fifth chains 11-9. Several membrane-binding spring teeth 11-11 are fixed on the spring tooth fixing rods 11-10. The membrane-binding spring teeth 11-11 slide slightly bent against the inner surface of the steel plate on one side of the main recovery frame 11-3.

[0067] A film shredding box 11-6 is fixedly connected to the frame 1. The film shredding box 11-6 is located on the top of the main recovery frame 11-3, near the steel plate of the main recovery frame 11-3. The film shredding box 11-6 has an opening facing the main recovery frame 11-3.

[0068] like Figure 12 The first hinge part 12-1 of the hinge connection 12 is fixed to the frame 1 by bolts, and the second hinge part 12-2 is fixed to the main frame 11-3 of the film recycling by bolts. The first hinge part 12-1 and the second hinge part 12-2 are connected by pins.

[0069] like Figure 13 The telescopic connecting rod 13 includes an internally threaded rod 13-2, with externally threaded rods 13-1 threaded to both ends of the internally threaded rod 13-2. The two externally threaded rods 13-1 are respectively hinged to the frame 1 and the main recovery frame 11-3. Locking nuts 13-3 are threaded to the externally threaded rods 13-1, and the two locking nuts 13-3 abut against the two ends 13-2 of the internally threaded rod. Loosening the locking nuts 13-3 and rotating the internally threaded rod 13-2 can adjust the length of the telescopic connecting rod 13, thereby cooperating with the hinged connection 12 to adjust the angle of the film recycling mechanism 11.

[0070] like Figure 1 , Figure 14 As shown, the first sprocket shaft 11-7 is rotatably connected to the main recovery frame 11-3 via the first seated bearing 11-5; the second sprocket shaft 11-13 is rotatably connected to the main recovery frame 11-3 via the second seated bearing 11-14; a film crushing box mounting beam 1-9 is welded above the frame 1, and the film crushing box 11-6 is welded to the film crushing box mounting beam 1-9 via a welding block 11-4 welded to its lower bottom surface;

[0071] When the broken film is tucked, the first transmission component drives the first sprocket shaft 11-7 to rotate, which in turn drives the five-chain 11-9 to rotate, thereby driving the film-tucking spring teeth 11-11 to move. After the film spring teeth 11-11 enter the soil and tuck the broken film, they adhere tightly to the upper surface of the bottom steel plate of the main recovery frame 11-3 (at this time, the film spring teeth 11-11 are slightly bent under the force) and are conveyed upward to the film-breaking box 11-6. After reaching the position of the film-breaking box 11-6, the film-tucking spring teeth 11-11 detach from the bottom steel plate and straighten. The film-tucking spring teeth 11-11 change from a bent state to a straight state. During this process, an elastic force is generated on the broken film, which is then sent into the film-breaking box 11-6; thus completing the automatic recovery of the broken film.

[0072] like Figure 1 , Figure 3 As shown, in a further optimized scheme, the film-lifting assembly includes several teeth 4-6 fixed to the frame 1 and two film shovels 3 on both sides. The several teeth 4-6 are located between the two film shovels 3. The teeth 4-6 are located at the end of the film-winding roller sleeve 15-2 away from the main recovery frame 11-3. The discharge end of the teeth 4-6 is fixedly connected to a guide rod 4-7. The discharge end of the guide rod 4-7 is connected to the inlet end of the film-soil separation assembly.

[0073] A first welding plate 4-1 and a second welding plate 4-2 are welded onto the frame 1. Several main teeth 4-3 are welded linearly and evenly on the upper surface of the first welding plate 4-1 and the lower surface of the second welding plate 4-2. A reinforcing rod 4-4 is welded between two adjacent main teeth 4-3. A tooth head mounting seat 4-5 is installed at the front end of the main teeth 4-3. The tooth head 4-6 is fixed to the tooth head mounting seat 4-5 by a semi-circular head bolt for easy disassembly and replacement. A guide rod 4-7 is welded to the tooth head mounting seat 4-5. When the film is lifted, the two side film shovels 3 enter the soil to lift the side film of the ground film. The tooth head 4-6 lifts the whole film. The lifted whole film and soil enter the top of the tooth head 4-6 and then pass through the guide rod 4-7. Some soil falls from between the guide rods 4-7, realizing the initial separation of film and soil. The discharge end of the guide rod 4-7 is connected to the inlet end of the film-soil separation component.

[0074] like Figure 1 , Figure 4 , Figure 15As shown in the further optimized scheme, the membrane-soil separation assembly includes two lifting chain drive shafts 9-1 located between the toothed head 4-6 and the film winding roller sleeve 15-2. Both ends of the lifting chain drive shafts 9-1 are connected to driven lifting chain wheels 9-4 via lifting chains 9-2. The driven lifting chain wheels 9-4 are rotatably connected to the frame 1. A first sprocket 23 is fixedly connected to one end of the lifting chain drive shaft 9-1 near the film winding roller sleeve 15-2. The lifting chain drive shaft 9-1 is connected to the first transmission assembly. Several lifting chain meshing shafts 9-3 are fixedly connected between the two lifting chains 9-2. The lifting chain 9-2 is inclined and its lower end is the feed end. The feed end of the lifting chain 9-2 near the tooth 4-6 is located below the discharge ends of several guide rods 4-7. The discharge end of the lifting chain 9-2 near the tooth 4-6 is located above the feed ends of the adjacent lifting chain 9-2. The discharge end of the lifting chain 9-2 near the film roll sleeve 15-2 is located above several film roll sleeves 15-2. A disc 25 is fixedly connected to the driving wheel shaft 9-1 of the lifting chain. Several grooves are opened on the disc 25. The grooves are slidably connected to the meshing shaft 9-3 of the lifting chain.

[0075] A soil-crushing roller 6 is rotatably connected to the frame 1. The soil-crushing roller 6 is located above the feed end of the two lifting chains 9-2 near the toothed head 4-6. The soil-crushing roller 6 is connected to the first transmission assembly.

[0076] The plastic film on the guide rod 4-7 enters between the two lifting chains 9-2 and is supported by the lifting chain meshing shaft 9-3. The first transmission component drives the lifting chain drive wheel shaft 9-1 to rotate, which in turn drives the lifting chain 9-2 to rotate, thereby driving the plastic film on the lifting chain meshing shaft 9-3 to be conveyed upward. During the conveying process, it first passes through the soil crushing roller 6. There is a certain gap between the soil crushing roller 6 and the lifting chain meshing shaft 9-3. Larger soil clods cannot pass through this gap and thus roll directly from the lifting chain meshing shaft 9-3 to the ground. When smaller soil clods pass through, the soil crushing roller 6 and the lifting chain meshing shaft 9-3 squeeze them to break them up, so that soil and other impurities can fall to the ground through the gap between the lifting chain meshing shafts 9-3 under the action of machine vibration. Through the two-stage lifting and impurity removal, the impurity removal effect on the plastic film is improved, and the film-soil separation effect is improved. The whole film conveyed from the second lifting chain meshing shaft 9-3 enters the film winding roller 15-2 for winding.

[0077] like Figure 16As shown, in a further optimized scheme, the first transmission assembly includes a gearbox 7 fixedly connected to the frame 1. A seventh sprocket 26 is fixedly connected to the output shaft of the gearbox 7. An eighth sprocket 27 is fixedly connected to one end of the soil crushing roller 6. Second double-row sprockets 28 are fixedly connected to the two lifting chain drive wheel shafts 9-1 respectively. A ninth sprocket 29 is fixedly connected to the first sprocket shaft 11-7. The seventh sprocket 26 is connected to the eighth sprocket 27 via a seventh chain. The seventh sprocket 26 is also connected to the second double-row sprocket 28 near the tooth head 4-6 via a seventh chain. The two second double-row sprockets 28 are connected via an eighth chain. The second double-row sprocket 28 away from the tooth head 4-6 is connected to the ninth sprocket 29 via a ninth chain.

[0078] The gearbox 7 drives the soil crushing roller 6, the lifting chain drive wheel shaft 9-1, and the first sprocket shaft 11-7 to rotate.

[0079] like Figure 1 , Figure 5 As shown, in a further optimized scheme, the walking and lifting mechanism 16 includes a main frame 16-3 hinged to the bottom of the frame 1, with walking wheels 16-1 fixed to both sides of the main frame 16-3, and the cylinder end of a hydraulic cylinder 17 hinged to one side of the frame 1, with the piston end of the hydraulic cylinder 17 hinged to the main frame 16-3.

[0080] A limiting bolt 18 is fixedly connected to the side of the frame 1 near the hydraulic cylinder 17, and the limiting bolt 18 is located below the hydraulic cylinder 17; the main frame 16-3 is fixedly welded to the axle 16-5 of the traveling wheel 16-1, and the main frame 16-3 is hinged to the frame 1 through the first pin hole 16-4, and the piston rod end of the hydraulic cylinder 17 is hinged through the second pin hole 16-2. The height of the implement off the ground can be controlled by controlling the extension and retraction of the hydraulic cylinder 17. When the implement is traveling on the road, after adjusting the height off the ground, the top of the limiting bolt 18 abuts against the hydraulic cylinder 17, thereby limiting the hydraulic cylinder 17 to prevent accidental pressure leakage and damage to the implement; two front limit wheels 2 are rotatably connected to the bottom front end of the frame 1, and a traction frame 5 is fixedly connected to the top front end of the frame 1.
