Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural equipment, and particularly relates to a film winding device and a residual film recycling machine. Technical Background

[0002] Existing drum-type residual film recycling machines are usually towed by an agricultural tractor and driven by the rear output shaft of the agricultural tractor; under the drive of the rear output shaft of the agricultural tractor, the grid conveyor belt conveys soil, root stubbles and plastic films backward. During the conveying process, the grid conveyor belt can automatically remove part of the soil. A small part of the soil, root stubbles and plastic films are conveyed into the drum screen. The drum screen is generally cylindrical and has a grid structure. Under the action of the transmission mechanism, the drum screen rotates, and the root stubbles and plastic films are screened out and conveyed into the collection box at the rear.

[0003] This type of residual film recycling machine can recycle residual films, and at the same time can realize root stubble collection, and the root stubble soil removal effect is good; however, the following problems mainly exist in actual use: Some of the plastic films after collection are wrapped around the root stubbles and mixed with the root stubbles, which is not conducive to the effective recycling and utilization of the plastic films. If the root stubbles are burned, it is easy to pollute the environment due to the mixture of plastic films; during use, the plastic films are easily hung on the rod bodies of the drum screen and block the screen holes, and the cleaning process is time-consuming and laborious.

[0004] There is a drum-type residual film recycling machine with a publication number of CN216292086U and a patent name of "A Drum-Type Residual Film Recycling Machine"; this residual film recycling machine includes a frame, a grid conveyor belt arranged on the front side of the frame, a drum screen arranged on the frame and cooperating with the rear side of the grid conveyor belt, a first transmission mechanism arranged on the frame and cooperating with the grid conveyor belt and the drum screen, and a root stubble collection box arranged on the frame and cooperating with the rear side of the drum screen.

Embodiment

[0036] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The following will further describe the technical solutions of the present invention in conjunction with the drawings of the embodiments of the present invention. The present invention is not limited to the following specific embodiments.

[0037] It should be understood that the same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc. indicating the orientation or positional relationship, they are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0038] In a specific embodiment of the present invention, there is a film winding device 5 for separating, collecting and compressing the residual film from the mixture of the residual film and soil.

[0039] A film winding device 5, as Figure 5 shown, includes:

[0040] A wire pay-off mechanism 502, a wire stranding mechanism 504, and a winding film wire 506. The wire pay-off mechanism 502 includes at least one bobbin 5021. One end of the winding film wire 506 is wound around the bobbin 5021, and the other end of the winding film wire 506 is fixed. And the winding film wire 506 passes through the wire stranding mechanism 504. At least one of the wire pay-off mechanism 502 and the wire stranding mechanism 504 can drive the winding film wire 506 to rotate around the rotation axis 5082 to form a rotating surface.

[0041] In a preferred embodiment, the wire pay-off mechanism 502 further includes a pay-off disc 5022 and a mounting base A 5023. The bobbin 5021 is rotatably connected to the pay-off disc 5022, and the pay-off disc 5022 is rotatably connected to the mounting base A 5023. The pay-off disc 5022 can be driven by a driving component A 501 to rotate around a rotation center on the mounting base A 5023. The bobbin 5021 is arranged at a position far from the rotation center. The wire stranding mechanism 504 is fixed. The rotation of the pay-off disc 5022 drives the rotation of the bobbin 5021, and the rotating cylinder drives the winding film wire 506 to form a rotating surface. When the residual film falls onto the rotating surface, the winding film wire 506 forming the rotating surface catches the residual film. During the rotation of the winding film wire 506, the residual film hanging on the winding film wire 506 is wound into a relatively tight roll by the winding film wire 506 rotating around the rotation axis 5082, initially achieving the purpose of collecting and compressing the residual film.

[0042] Furthermore, if there are at least two winding film wires 506 and bobbins 5021, in this embodiment, while the multiple winding film wires 506 can continuously rotate with the rotation of the wire pay-off mechanism 502, they can perform a film stranding action to twist the residual film collected on the winding film wires 506 into one strand. The demarcation point between the twisted single strand of winding film wire 506 and the multiple winding film wires 506 is the stranding point. The film stranding action can twist and compress the residual film on the multiple winding film wires 506 into a tight thick rope along with the winding film wires 506. The arrangement of the multiple winding film wires 506 greatly improves the compression degree of the residual film by the winding film device 5.

[0043] In another preferred embodiment, the wire stranding mechanism 504 includes a mounting base B 5041 and a rocker arm 5042. The rocker arm 5042 further includes a rotating cylinder, a rocker handle, and a guiding ring. The rocker handle is L-shaped. The rotating cylinder and the guiding ring are respectively arranged at the two end parts of the L-shape. The rotating cylinder is in the shape of a cylindrical barrel, and the rotating cylinder is rotatably connected to the mounting base B 5041. Teeth are provided at the front end of the rotating cylinder and can cooperate with the gear on the driving component B 503. The winding film passes through the rotating cylinder and the guiding ring. The driving component B 503 drives the rocker arm 5042 to rotate alone or rotate simultaneously with the pay-off disc 5022, and can also make the winding film wire 506 form a rotating surface.

[0044] Furthermore, as above, if there are no less than two film wrapping lines 506 and wire drums 5021, and there is a speed difference between the rocker arm 5042 and the wire pay-off reel 5022, a more complete solution can also be formed to improve the compression degree of the collected residual film.

[0045] Furthermore, the wire drum 5021 is connected to the wire pay-off reel 5022 via a tensioning component 5024, which provides tensioning force for the wire drum 5021, so that the wire drum 5021 can tighten the film wrapping line 506 when paying out the line, thereby preventing the weight of the residual film collected by the film wrapping line 506 from being too heavy and bending the film wrapping line 506 beyond the maximum distance between the wire drum 5021 and the rotating axis 5082 of the pay-off mechanism 502, thereby ensuring that the rotation trajectory of the film wrapping line 506 is stably maintained on an ideal preset trajectory.

[0046] Further, such as Figure 5 As shown, the film wrapping device 5 also includes a wire take-up mechanism 507, which is arranged between the wire unwinding mechanism 502 and the wire twisting mechanism 504. The wire take-up mechanism 507 is provided with a plurality of wire take-up holes, through which the film wrapping wire 506 can pass. The wire take-up holes have different heights. By selecting different wire take-up holes, the position and height of the central axis of the rotating surface formed by the film wrapping wire 506 can be adjusted, so that the film wrapping device 5 can adapt to different operating conditions, and can control the relative position of the rotating trajectory and the twisting point of the film wrapping wire 506 on the residual film recovery machine, so that the residual film falling on the film wrapping wire 506 can be better twisted into one strand, thereby further improving the applicability and working efficiency of the residual film recovery machine.

[0047] In order to further facilitate the collection and processing of the wrapped wire 506, in a preferred embodiment, the wrapped wire device 5 also includes a winding mechanism 508, the winding mechanism 508 includes a winding assembly 5081, a rotating shaft 5082 and a bracket 5083, the winding assembly 5081 is an hourglass shape, the winding assembly 5081 includes a winding terminal A50811 and a winding terminal B50812, the winding terminal A50811 and the winding terminal B50812 are connected by an axially detachable mortise and tenon structure, the rotating shaft 5082 is rotatably mounted on the bracket 5083, the winding mechanism 508 is mounted on the rotating shaft 5082 by a keyway structure, the winding segments A and B are provided with through axial holes, the axial holes are provided with grooves, the rotating shaft 5082 has a corresponding key, and when the rotating shaft 5082 rotates, the winding terminal is driven to rotate by the keyway structure. The bracket 5083 further includes end covers 50831 , which are disposed on both sides of the rotating shaft 5082 . The end covers 50831 can be opened, and when the end covers 50831 are opened, the rotating shaft 5082 can be axially withdrawn.

[0048] Further, after a certain amount of winding film line 506 is wound on the winding mechanism 508, by opening the end cover 50831 on the bracket 5083, the rotating shaft 5082 can be pulled out from the opened end cover 50831. At this time, the winding assembly 5081 can be lifted down from the winding film device 5. After the winding assembly 5081 is lifted down, it can be disassembled into the winding terminal A 50811 and the winding terminal B 50812 through the mortise and tenon structure, so as to conveniently and quickly unload the winding film line 506 tightly wound on the winding mechanism 508.

[0049] Further, the winding film device 5 further includes a driving component A 501 for driving the wire unwinding mechanism 502 to rotate around the axis and a driving component B 503 for driving the wire twisting mechanism 504 to rotate around the axis.

[0050] In a specific embodiment of the present invention, a residual film recycling machine can shovel up the mixture of plastic film and soil from the field, separate the plastic film from the soil, then collect them together, and finally compress them into a tight cylindrical shape for subsequent treatment of the residual film.

[0051] Further, the winding film device 5 further includes a driving component A 501 for driving the wire unwinding mechanism 502 to rotate around the axis, a driving component B 503 for driving the wire twisting mechanism 504 to rotate around the axis, and a driving component C 505 for driving the winding mechanism 508 to rotate around the axis.

[0052] As Figure 1 shown, the residual film recycling machine includes: a frame 1, a soil lifting mechanism 2, a conveyor belt 3, and a sieve cylinder 4. The soil lifting mechanism 2 is arranged at the front end of the frame 1. When the residual film recycling machine moves forward, it can shovel up the residual film and soil, and the shoveled residual film and soil fall onto the conveyor belt 3 arranged at the rear side of the soil lifting mechanism 2 on the front side of the frame 1. The conveyor belt 3 can transport the plastic film and soil backward, and the plastic film and soil on the conveyor belt 3 are transported into the sieve cylinder 4 arranged at the rear side of the conveyor belt 3 on the frame 1. The sieve cylinder 4 can rotate to conduct preliminary screening of the soil and the residual film. The residual film recycling machine further includes the winding film device 5 as described in any one of the above, and the residual film recycling machine has the functions of the winding film device 5 as described in any one of the above.

[0053] In a preferred embodiment, the residual film recycling machine further includes a transmission mechanism. The transmission mechanism is arranged on the frame 1. The transmission mechanism further includes a transmission component D and a transmission component E. The transmission component D can cooperate to drive the conveyor belt 3 to transport the soil and residual film shoveled by the soil lifting mechanism 2 to the sieve cylinder 4, and the transmission component E drives the sieve cylinder 4 to rotate. During the rotation of the sieve cylinder 4, the soil is screened out from the residual film and the residual film is carried to the apex and falls onto the rotation trajectory of the winding film line 506, and finally is wound around the winding film line 506.

[0054] Furthermore, the screen surface of the screen drum 4 adopts a wave-type screen surface, which can generate secondary vibration with a small amplitude, thereby reducing the adhesion and clogging of sticky materials or fine particles. The screen drum 4 is installed on the frame 1 at an angle of 1 to 20 degrees to the horizontal plane. The screen drum 4 is rotated by the transmission component B, and the soil and residual film transported to the screen drum 4 by the conveyor belt 3 are shaken off due to the secondary vibration of the screen during the rotation process. The shaken off soil passes through the screen and falls into the field. The screen drum 4 drives the wave-type screen to rotate together, and the residual film is brought to the top of the screen drum 4 by the wave-type screen, and then falls on the film wrapping line 506.

[0055] like Figure 2 As shown, in a preferred embodiment, the residual film recovery machine includes a collecting box 6, and the collecting box 6 is arranged on the frame 1 and cooperates with the rear side of the screen drum 4. When part of the residual film is separated from the soil by the screen drum 4 and is not collected on the film wrapping line 506, this part of the residual film is transported to the collecting box 6 by the screen drum 4, further increasing the recovery rate of the residual film by the residual film recovery machine.

[0056] The following provides a preferred implementation process of the residual film recovery machine provided by the present invention. It is worth noting that the actual implementation process of the technical solution adopted by the present invention is not limited to the following process.

[0057] When the residual film recovery machine is driven forward by the tractor, the earth-lifting mechanism 2 can scoop up the residual film and soil, and the residual film and soil scooped up by the earth-lifting mechanism 2 fall onto the conveyor belt 3 arranged on the rear side of the earth-lifting mechanism 2 on the front side of the frame 1. The transmission component D can cooperate with the driving conveyor belt 3 to transport the soil and residual film scooped up by the earth-lifting mechanism 2 backward, and finally transport them to the screen drum 4, thereby avoiding the residual film and soil falling outside the screen drum 4, causing the problem of incomplete removal of the residual film. The transmission component E drives the screen drum 4 to rotate. The screen surface of the screen drum 4 adopts a wave-type screen surface, which can generate secondary vibration with a smaller amplitude, thereby reducing the adhesion and clogging of sticky materials or fine particles. The screen drum 4 is installed on the frame 1 at an angle of 1~20° with the horizontal plane. The screen drum 4 is rotated by the transmission component E, and the soil and residual film transported to the screen drum 4 by the conveyor belt 3 are shaken off due to the secondary vibration of the screen during the rotation. The shaken off soil passes through the screen and falls into the field. The screen drum 4 drives the wave-type screen to rotate together, and the residual film is lifted by the wave-type screen to the top of the screen drum 4 and falls down.

[0058] The film wrapping device 5 is arranged on the frame 1 and passes through the screen drum 4. The pay-off mechanism 502 is continuously driven to rotate by the replaced component A, thereby driving the film wrapping line 506 to rotate. By selecting the wire take-up holes at different heights, the rotation trajectory of the film wrapping line 506 and the relative position of the twisting point on the residual film recovery machine can be controlled, so that the residual film brought to the top of the screen drum 4 by the wave-type screen belt falls on the rotation trajectory of the film wrapping line 506, so that the residual film is wound on the film wrapping line 506, and the residual film wound on the film wrapping line 506 is twisted into A tight rope, the rope twisted from the film-wrapped wire 506 can pass through the wire take-up hole, and the rope passing through the wire take-up hole is finally coiled on the wire-winding mechanism 508 as the wire-winding mechanism 508 rotates. The wire-winding mechanism 508 collects enough residual film, opens the end cover 50831 of the bracket 5083 of the wire-winding mechanism 508, pulls out the rotating shaft 5082 axially, lifts the wire-winding assembly 5081 off the bracket 5083, and then separates the wire-winding terminal A 50811 and the wire-winding terminal B 50812, removes the film-wrapped wire 506 coiled into a tight wire coil, and concentrates on the next step of processing.

[0059] The residual film recovery machine also includes a collecting box 6, which is arranged on the frame 1 and cooperates with the rear side of the sieve drum 4. When part of the residual film is separated from the soil by the sieve drum 4 and is not collected on the film wrapping line 506, this part of the residual film is transported to the collecting box 6 by the sieve drum 4, further increasing the recovery rate of the residual film by the residual film recovery machine.

[0060] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
