Description

A self-propelled residual film recycling machine Technical Field

[0001] The present invention belongs to the field of agricultural machinery, relates to residual film recovery technology, and in particular to a self-propelled residual film recovery integrated machine. Background Art

[0002] Film mulching is a long-standing agricultural practice, effectively conserving heat and water, while increasing yields and incomes in arid, low-temperature regions. With its widespread adoption, my country's annual film usage has reached 1.45 million tons, covering approximately 300 million mu (approximately 1.67 hectares), both of which rank first in the world. However, plastic mulch films are not easily degraded. Residual film left on farmland not only affects crop growth and development but also hinders mechanized operations such as tillage, management, and harvesting. This has led to serious farmland contamination caused by residual film, necessitating urgent recovery.

[0003] Manual film recycling is time-consuming and labor-intensive. Mechanized film recycling involves shredding straw, collecting film residue, clearing debris, and rolling and baling. Existing film recycling equipment primarily relies on tractor-driven machines, which require a tractor for power. This results in low efficiency, poor stability, and a high impurity rate, as well as difficulty meeting all technical requirements for film recycling. Therefore, a new type of film recycling equipment is needed to overcome these shortcomings.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0062] One of the purposes of the present invention is to provide a self-propelled residual film recycling integrated machine, which can perform residual film recycling operations by self-configuring the cab, power system, driving system, steering system and braking system, etc., without the need for tractor traction or suspension. It can solve the problem that the existing traction-type residual film recycling machine still needs to be equipped with a tractor as power when operating, which not only has low operating efficiency, poor stability, high impurity content, but also is difficult to meet various technical indicators of residual film recycling.

[0063] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] Example 1

[0065] As shown in Figure 1, this embodiment proposes a self-propelled residual film recycling integrated machine 100, which includes a straw crushing device 1, a picking and cleaning device 3, a cab 4, an air intake system 9, a film stripping and conveying device 5, a round bale packaging device 6, a suspension system 10, a walking chassis 2 and a film unloading bracket 7. The straw crushing device 1 is assembled to the front end of the walking chassis 2 by a three-point suspension method, the picking and cleaning device 3 is installed on the belly of the walking chassis 2, the film stripping and conveying device 5 is installed above and behind the picking and cleaning device 3, the round bale packaging device 6 is installed at the tail of the walking chassis 2 and is located behind the film stripping and conveying device 5, the film unloading bracket 7 is installed below the round bale packaging device 6, and the suspension system 10 is arranged on the walking chassis 2 for hanging the picking and cleaning device 3 and the film stripping and conveying device 5. The walking chassis 2 is equipped with a power system, a driving system, a steering system and a braking system, etc. The walking chassis 2 preferably adopts a front-wheel drive and rear-wheel steering mode to provide walking power for the walking chassis 2, so that the self-propelled residual film recycling integrated machine 100 can perform the joint operation of residual film recycling in the current season without tractor traction or suspension, and the integrated operation technical route of residual film packaging and recycling can realize nine operation processes at one time, including straw crushing and returning to the field, edge film removal, soil and debris removal, widening row film removal, picking up ground film, fan film removal, residual film transportation, residual film removal, and residual film packaging, etc., realizing the integration of intelligent self-driving of equipment, straw crushing and returning to the field, and serialized residual film recycling processes, forming a set of high-performance self-propelled residual film recycling integrated machine, which has the advantages of high operating efficiency, strong stability, and low impurity rate, and can meet various technical indicators of residual film recycling, and solves the problem that the existing traction-type residual film recycling machine needs to be equipped with a tractor as power when operating, which not only has low operating efficiency, poor stability, and high impurity rate, but also is difficult to meet various technical indicators of residual film recycling.

[0066] In this specific embodiment, as shown in Figure 2, the straw crushing device 1 is preferably connected to the front end of the walking chassis 2 in a three-point manner via a front suspension. The walking chassis 2 transmits power to the straw crushing device 1 via a front power output. The straw crushing device 1 serves as the first step in the integrated operation technology route of the self-propelled residual film recycling machine 100. When it is in operation, the straw standing on the surface is drawn into it and crushed. The crushed straw is then discharged to one side of the machine through a side discharge method, providing an excellent operating environment for subsequent residual film recovery. The straw crushing device 1 is an existing mature device and will not be described in detail here.

[0067] In this specific embodiment, as shown in Figures 3-10, the debris collection and removal device 3 includes a frame 36, on which are arranged, from front to back, a front limiting roller 31, a debris collection and removal conveyor device 32, a pickup roller 33, a film-lifting gear assembly 34, and a rear limiting roller 35. The front limiting roller 31 and the rear limiting roller 35 are installed in the same manner and maintained at the same horizontal height, jointly limiting the height of the film-lifting gear assembly 34 and the pickup roller 33 above the ground. During operation, the front limiting roller 31 and the rear limiting roller 35 always contact the ground, limiting the depth to which the film-lifting gear assembly 34 and the pickup roller 33 can penetrate into the soil. The film-lifting tooth assembly 34 is installed obliquely below the picking roller 33, and the tooth tips of the film-lifting teeth 341 of the film-lifting tooth assembly 34 are lower than the horizontal bottom surfaces of the front limiting roller 31 and the rear limiting roller 35, and the film-lifting teeth 341 on the film-lifting tooth assembly 34 and the picking teeth on the picking roller 33 are arranged in an interlaced manner. The film-lifting teeth 341 penetrate into the soil to lift the film and pick up the residual film on the surface and shallow layers of the soil. The picking teeth extended by the picking roller 33 pick up the residual film, and at the same time, the broken soil and other impurities brought up enter the front cleaning and conveying device 32. As the cleaning and conveying device 32 continues to operate, the impurities are discharged to one side of the machine by the spiral conveyor 321, and the remaining residual film is transported to the feeding port of the picking and stripping device 5 along with the picking roller 33, and enters the next residual film processing link. In this embodiment, the picking roller 33 is a prior art. For details, reference may be made to the double-roller slide rail type residual film picking device disclosed in the invention patent publication number CN116615976A.

[0068] Furthermore, the above-mentioned debris picking and cleaning device 3 is mounted on a suspension system 10, which is primarily used to mount and raise and lower the debris picking and cleaning device 3 and the film stripping and conveying device 5. Specifically, the suspension system 10 includes two sets of lifting cylinders 101, each of which has its top end connected to the frame on the traveling chassis 2 and its bottom end connected to the suspension linkage 102. The frame 36 of the debris picking and cleaning device 3 is also connected to the suspension linkage 102. When the machine is not in operation, the lifting cylinders 101 can lift the debris picking and cleaning device 3 upward, clearing it from the ground. When the machine is in operation, the lifting cylinders 101 lower the debris picking and cleaning device 3, and the suspension linkage 102 activates, allowing the front and rear limiting rollers 31 and 35 of the debris picking and cleaning device to follow the ground. The structures of the front limiting roller 31 and the rear limiting roller 35 are generally the same, as shown in Figure 8, which can represent both the front limiting roller 31 and the rear limiting roller 35; the meaning of "31 (35)" in the figure is: the structure indicated by the lead line can represent both the front limiting roller 31 and the rear limiting roller 35.

[0069] Furthermore, in this embodiment, the debris removal conveying device 32 includes an auger 321 and a film-blocking rod 322. The debris removal conveying device 32 is designed to remove impurities picked up by the pickup roller 33. The film-blocking rod 322 is installed between the auger 321 and the pickup roller 33 to prevent residual film from entering the auger 321. The picking and debris removal device 3 picks up the residual film and simultaneously sends the thrown impurities into the auger 321. The auger 321 conveys the impurities to the outside of the machine, and the pickup roller 33 picks up the residual film and transports it to the film stripping conveying device 5.

[0070] Furthermore, in this embodiment, the film-lifting tooth assembly 34 includes a film-lifting tooth 341 and a film-lifting rod 342, and several film-lifting teeth 341 are arranged horizontally and fixed on the film-lifting rod 342. The film-lifting teeth 341 and the nail teeth of the picking roller 33 are staggered with each other, and preferably, the film-lifting teeth 341 on the film-lifting tooth assembly 34 are arranged in a staggered manner of one wide row and three narrow rows. The so-called "one wide row and three narrow rows" is shown in Figure 9. Several film-lifting teeth 341 are arranged at intervals on the film-lifting rod 342, and the interval between any two adjacent film-lifting teeth 341 is distributed according to the regular distribution of one wide spacing, three consecutive narrow spacings, one wide spacing, three consecutive narrow spacings, one wide spacing... Any two narrow spacings are the same, and any narrow spacing is smaller than the wide spacing. The film-lifting teeth 341 are arranged in a staggered pattern of one wide row and three narrow rows, aiming to lift wide rows of film. During operation, the wide rows (i.e., wide spacing) of the film-lifting teeth 341 correspond to the crop planting rows, and the three narrow rows (i.e., three consecutive narrow spacings) correspond to the crop planting row spacing.

[0071] In this specific embodiment, as shown in Figures 11 to 18, the film removal conveying device 5 is installed at an upper and rear side of the picking and cleaning device 3, and plays the role of film removal conveying and soil film separation in the residual film recovery operation technical solution. The film removal conveying device 5 is integrally connected to the picking and cleaning device 3, and can be adjusted up and down along with the picking and cleaning device 3 under the action of the suspension system 10. Specifically, the film removal conveying device 5 includes a film removal fan 51, an air discharge hood 52 and a conveying and cleaning device 53. The feeding port of the film removal fan 51 is connected to the picking roller 33 of the picking and cleaning device 3, and the discharge port of the film removal fan 51 is connected to the vibration belt 532 of the conveying and cleaning device 53. The air discharge hood 52 is installed above the vibration belt 532 and behind the discharge port of the film removal fan 51. The air discharge hood 52 and the conveying and cleaning device 53 together form a residual film conveying channel. After the picking roller 33 picks up the residual film in the previous link, it is transported to the feed port of the demolding conveying device 5. The demolding fan 51 runs at high speed, and a vacuum negative pressure is generated at the feed port to suck the residual film into the chamber of the demolding fan 51. As the demolding fan 51 runs, the residual film is transported to the air outlet of the demolding fan 51 and blown out by the wind, and enters the residual film conveying channel formed by the air vent hood 52 and the conveying and cleaning device 53. There are air vents on the top and side surfaces of the air vent hood 52, which are intended to unload the wind force generated by the demolding fan 51. When unloading the wind force, soil particles can be carried out of the machine at the same time. The conveying and cleaning device 53 includes a vibration device 531 and a vibration belt 532 with a mesh. During the residual film conveying process, the vibration device 531 below the vibration belt 532 continuously operates to beat the lower side of the vibration belt 532, so that the soil particles carried in the residual film fall back to the field through the mesh of the vibration belt 532. The residual film after cleaning enters the cavity of the round bale packaging device 6 through the film stripping and conveying device 5 and enters the next residual film processing link.

[0072] Furthermore, in this embodiment, as shown in Figure 11, it is preferred that the picking roller 33 and the film stripping fan 51 both rotate in a clockwise direction, and the rotation speed of the film stripping fan 51 is greater than that of the picking roller 33. When the residual film runs with the picking roller 33 to the feeding inlet of the film stripping fan 51, it can be drawn into the fan at a high speed of the film stripping fan 51 to achieve film stripping.

[0073] In this specific embodiment, as shown in Figures 19 to 21, the round bale packaging device 6 plays the role of packaging the residual film into bundles. The round bale packaging device 6 is installed at the rear of the self-propelled residual film recycling machine 100, and includes a bottom belt 61, a shoulder belt 62 and a packaging shell 63. The bottom belt 61 and the shoulder belt 62 are both arranged in the packaging shell 63, wherein the bottom belt 61 and the shoulder belt 62 are both conveyor belt structures, and the bottom belt 61 and the shoulder belt 62 are installed in a V-shaped form. As shown in Figure 21, the angle δ between the bottom belt 61 and the shoulder belt 62 is an acute angle, the bottom belt 61 and the shoulder belt 62 run in the same direction, and the running speed of the bottom belt 61 is less than the running speed of the shoulder belt 62. After being de-filmed and cleaned by the de-filming conveyor 5, the residual film falls onto the bottom belt 61 inside the cavity of the round bale packaging device 6. The operation of the bottom belt 61 generates friction between the residual film and the bottom belt 61. Under the action of this friction, the residual film is transported to the surface of the shoulder belt 62 along with the bottom belt 61. Since the shoulder belt 62 and the bottom belt 61 are installed at an acute angle δ, the installation height of the lower driving wheel of the shoulder belt 62 is lower than the installation height of the right end driving wheel of the bottom belt 61, and the operating speed of the shoulder belt 62 is greater than the operating speed of the bottom belt 61. Therefore, the residual film is driven by the shoulder belt 62 and continuously flipped into a roll and rolled into a package at the angle between the bottom belt 61 and the shoulder belt 62. With the continuous operation of the self-propelled residual film recycling integrated machine 100, a cylindrical residual film package 8 of a certain volume (characterized by a certain diameter) is finally generated in the cavity of the round bale packaging device 6.

[0074] Furthermore, in this embodiment, the top of the packaging shell 63 of the round bale packaging device 6 is preferably hinged to the frame of the walking chassis 2, and unpacking cylinders are arranged on the left and right sides of the bottom of the packaging shell 63 respectively. One end of the unpacking cylinder is connected to the frame of the walking chassis 2, and the other end is connected to the bottom of the packaging shell 63. When the residual film on the bottom belt 61 of the round bale packaging device 6 is packed into a certain volume, the unpacking cylinder applies a thrust to the bottom of the packaging shell 63, so that the round bale packaging device 6 composed of the packaging shell 63, the bottom belt 61 and the shoulder strap 62 is flipped upward at a certain angle around the top hinge axis of the packaging shell 63, so that the residual film package 8 can fall freely from the round bale packaging device 6.

[0075] In this specific embodiment, as shown in Figures 22-23, a schematic diagram of the integrated technology for collecting and recycling residual film in a self-propelled integrated residual film recycling machine 100 is provided. Specifically, the process involves film removal by the film-removing tooth assembly 34, film collection by the collection roller 33, film removal by the film-removing blower 51, film removal by the conveying and cleaning device 53, and packaging by the round bale packaging device 6. The self-propelled integrated residual film recycling machine 100 continuously collects residual film, ultimately forming a certain volume of round bales of residual film within the chamber of the round bale packaging device 6. Subsequently, the bale opening cylinders on both sides of the round bale packaging device 6 generate thrust, jointly pushing the round bale packaging device 6 to flip it to a certain angle, allowing the residual film bales 8 to slide freely from the bottom belt 61 and fall onto the film unloading bracket 7 below.

[0076] In this specific embodiment, as shown in Figures 24 to 26, the film unloading bracket 7 is installed below the round bale packaging device 6 and is used to temporarily store the residual film package 8 during field operations. Specifically, the film unloading bracket 7 includes a tilting cylinder 71, a bracket 72 and a tilting frame 73. The bracket 72 is arranged at the rear end of the walking chassis 2, and the tilting frame 73 is arranged on the bracket 72. The rear end of the tilting frame 73 is hinged to the bracket 72. The tilting cylinder 71 is connected between the rear end of the tilting frame 73 and the bracket 72. When the piston rod of the tilting cylinder 71 is extended, the tilting frame 73 can be pressed against the bracket 72. At this time, the tilting frame 73 can normally support the residual film package 8. When the piston rod of the tilting cylinder 71 is retracted, it drives the rear end of the tilting frame 73 to tilt downward, thereby causing the head end of the tilting frame 73 to tilt upward and backward. The entire tilting frame 73 is in a backward flip state, and the residual film package 8 thereon slides to the ground. During the specific working process, after the residual film package 8 is packed and falls onto the turning frame 73, the machine continues to work with the residual film package 8. When the operation reaches the edge of the field, the turning cylinder 71 acts on the turning frame 73 to generate thrust to make it turn backward around the axis, so that the residual film package 8 falls to the ground smoothly, realizing the residual film recovery operation without stopping the film unloading.

[0077] In this specific embodiment, as shown in FIG1 , when the self-propelled residual film recycling integrated machine 100 is in operation, a large amount of dust is generated by the continuous operation of the straw crushing device 1, the picking and cleaning device 3, and the film stripping and conveying device 5. Based on this, this embodiment is provided with an air intake system 9 above the cab 4. The air intake system 9 includes a ventilation duct, the air inlet of the ventilation duct is provided at the front upper part of the cab 4, and the air outlet of the ventilation duct is connected to the engine air intake on the walking chassis 2.

[0080] When the above-mentioned self-propelled residual film recycling integrated machine 100 proposed in the present technical solution is in operation, the front straw crushing device 1 crushes the straw and discharges it to the field sideways, the picking and cleaning device 3 removes the film through the film-lifting tooth assembly 34, the picking roller 33 picks up the residual film, and the cleaning conveying device 32 discharges impurities sideways. The picked-up residual film is further cleaned of soil and impurities through the film stripping conveying device 5 and then conveyed into the round bale packaging device 6. After being packaged into rolls, the packages are unloaded and fall into the film unloading bracket 7. When the machine operates to the edge of the field, the turning frame 73 turns over to make the residual film package fall smoothly to the ground, so that the recovered residual film package is concentrated at the edge of the field, reducing the work intensity of picking up and collecting the residual film package. The self-propelled film recycling machine 100 can complete nine operating processes at one time, including straw crushing and returning to the field, edge film removal, soil and debris removal, wide film row removal, picking up ground film, film removal with a fan, film transportation, film removal from the soil, and film packaging.
