Description

Technical Field

[0001] This invention relates to the field of waste plastic film collection equipment, and particularly to an involute-shaped film-picking and bundling integrated machine. Background Technology

[0002] With the development of the rural economy and the increase in farmers' income, the area covered by plastic film mulching has also increased. Plastic film mulching technology has the effects of increasing soil temperature, preventing seedling frost damage, resisting drought and conserving moisture, suppressing weed growth, and extending the crop growing season, thus significantly improving crop quality and yield. This technology was introduced to my country in the late 1970s and was immediately welcomed by farmers, being widely promoted in cold, arid, semi-arid, and saline-alkali areas. Statistics show that my country's plastic film mulching area has exceeded 12 million hectares, making it the world's largest plastic film mulching country. Almost all agricultural surface mulching films in my country are polyethylene hydrocarbon plastic films. These films are easily broken due to weathering under sunlight and are extremely difficult to degrade under natural conditions, remaining in the soil for 200-400 years. They are usually mixed with crop roots, stubble, and soil, making recycling difficult. The failure of farmers to properly clean up residual plastic film after planting has led to a serious situation of crop growth and yield reduction. Currently, the main method for controlling residual plastic film pollution is recycling. However, manual collection is labor-intensive and inefficient. Mechanized recycling can overcome the drawbacks of manual collection and is the future direction for controlling residual plastic film pollution.

[0003] To address the aforementioned technical issues, many waste plastic film collection and baling machines have emerged on the market. However, in actual operation, it has been found that these machines, in order to achieve a good film-lifting effect, have designed the film-lifting teeth of the film-lifting device to be 40mm, resulting in high resistance to film shoveling during operation. At the same time, the film-lifting device has low structural strength, and with the high film-lifting resistance during operation, the entire film-lifting device is prone to deformation and failure. Secondly, the film-picking devices on existing equipment are mostly telescopic teeth or roller structures, and residual film often gets tangled on them, making it impossible for the film-picking device to pick up the residual film and feed it into the upper film chain plate of the waste plastic film collection and baling machine. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an involute-shaped film-picking and bundling integrated machine.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] The involute film-picking and bundling machine includes:

[0007] The film lifting device is located at the front end of the residual film picking and bundling machine;

[0008] The involute film picking device is located at the front end of the residual film picking and bundling machine and behind the film lifting device.

[0009] The film-forming device includes:

[0010] A fixed square tube is horizontally installed at the front end of the residual film picking and bundling machine;

[0011] Several film-raising rods are arranged parallel to each other and perpendicular to each other on the front side of the fixed square tube, and the structure of the film-raising rods is circular steel;

[0012] Several connecting plates are correspondingly installed at the head of each film-lifting rod;

[0013] Several film-forming teeth are obliquely arranged on the upper part of each connecting plate, and the width of the film-forming teeth is 18mm.

[0014] The involute film-picking device includes:

[0015] The film-picking plate drive shaft is horizontally set on the residual film picking and baling machine. One end of the drive shaft is connected to the power source of the residual film picking and baling machine, so that the film-picking plate drive shaft can rotate.

[0016] The involute film removal plate fixing shaft is horizontally set behind the film picking plate drive shaft, and its two ends are fixedly installed on the frame of the residual film picking and bundling machine.

[0017] Several vertically arranged involute stripping plates are mounted on the front end of the stripping plate drive shaft and on the rear end of the involute stripping plate fixing shaft.

[0018] Several vertically arranged film-picking plates are evenly fixed on the film-picking plate drive shaft;

[0019] Two or three involute stripping plates form a work group, and a film picking plate is set between two adjacent involute stripping plates in each work group.

[0020] Anti-winding bushings are installed between adjacent work groups, and the anti-winding bushings are fitted onto the film-picking plate drive shaft.

[0021] The rear end of the involute stripping plate is fitted onto the fixed shaft of the involute stripping plate via a positioning sleeve.

[0022] The front sides of the residual film picking and baling machine are respectively equipped with grass-pulling roller devices, and the power input part of the grass-pulling roller device is connected to the power source of the residual film picking and baling machine.

[0023] The distance between the rear end of the film-lifting tooth and the feeding end of the upper film chain plate of the residual film picking and baling machine is 6-10mm, which can prevent straw and film from getting stuck between the rear end of the film-lifting tooth and the feeding end of the upper film chain plate.

[0024] The beneficial effects of this invention are:

[0025] 1. This invention reduces the resistance to film scraping by designing the width of the film-lifting teeth to 18mm, and increases the strength of the film-lifting device by changing the film-lifting rod from a steel plate to a round steel bar.

[0026] 2. The involute film-lifting device consists of multiple working groups, each composed of 2 film-lifting plates and 3 involute film-removing plates. The involute film-removing plates are fixed to the machine via their fixed shafts and do not rotate. Their outer contour is a standard involute. The film-lifting plates rotate counterclockwise via their drive shafts, with their working ends being arcs. The film-lifting plates pick up residual film and weeds, forming an obtuse angle when they exit the involute film-removing plates, allowing the residual film and weeds to detach smoothly. A bushing is installed on the drive shaft of the film-lifting plates, fixed to the machine and not rotating to prevent film entanglement. Furthermore, the film-lifting plates can tear apart residual film, preventing the formation of soil pockets and significantly improving the film-soil separation rate, especially effective in environments where one-year films and thick films retain relatively intact mulch film. Third, compared to transmission devices such as telescopic teeth and rollers, the involute film lifting device creates a larger space between each working group, allowing the shoveled soil to flow into the lifting chain for separation, solving the blockage problem caused by soil accumulation in front of the lifting chain, and reducing machine resistance.

[0027] 3. The distance between the film-raising device and the upper film chain plate was optimized, which solved the problem of straw and film getting stuck between the film-raising device and the lifting chain. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0034] like Figure 1 and Figure 5As shown, the involute-shaped film-picking and baling integrated machine includes: a film-lifting device 1, located at the front end of the film-picking and baling machine 3; and an involute-shaped film-lifting device 4, located at the front end of the film-picking and baling machine 3 and behind the film-lifting device 1. The film-lifting device 1 includes: a fixed square tube 101 horizontally positioned at the front end of the film-picking and baling machine 3; several film-lifting rods 102, parallel and perpendicular to each other, positioned in front of the fixed square tube 101, and the film-lifting rods 102 are made of round steel; several connecting plates 103, correspondingly positioned at the head of each film-lifting rod 102; and several film-lifting teeth 104, inclinedly positioned on the upper part of each connecting plate 103, with a width of 18mm. The distance between the rear end of the film-lifting teeth 104 and the feeding end of the upper film chain plate of the film-picking and baling machine 3 is 6-10mm, which prevents straw and film from being caught between the rear end of the film-lifting teeth 104 and the feeding end of the upper film chain plate.

[0035] like Figures 2 to 4 As shown, the involute film picking device 4 includes: a film picking plate drive shaft 43 horizontally arranged on the residual film picking and bundling machine 3, one end of which is connected to the power source of the residual film picking and bundling machine 3, so that the film picking plate drive shaft 43 can rotate; an involute film removal plate fixing shaft 46 horizontally arranged on the rear side of the film picking plate drive shaft 43, both ends of which are fixedly installed on the frame of the residual film picking and bundling machine 3; a plurality of vertically arranged involute film removal plates 41, the front end of which is fitted on the film picking plate drive shaft 43 and the rear end of which is fitted on the involute film removal plate fixing shaft 46; a plurality of vertically arranged film picking plates 42, which are evenly fixed on the film picking plate drive shaft 43; wherein, two or three involute film removal plates 41 form a working group, and in each working group, a film picking plate 42 is arranged between two adjacent involute film removal plates 41.

[0036] like Figure 3 As shown, an anti-winding bushing 44 is provided between adjacent work groups, and the anti-winding bushing 44 is fitted onto the film picking plate drive shaft 43.

[0037] like Figure 3 As shown, the rear end of the involute stripping plate 41 is fitted onto the involute stripping plate fixing shaft 46 via a positioning sleeve 45.

[0038] like Figure 1 As shown, the front sides of the residual film picking and baling machine 3 are respectively equipped with grass-pulling roller devices 2, and the power input part of the grass-pulling roller device 2 is connected to the power source of the residual film picking and baling machine 3.

[0039] This invention is a suspended implement. In use, the tractor inputs power to drive the implement forward. The weeding roller device 2 operates to clear all weeds encountered during the equipment's movement. The film-lifting device 1's film-lifting teeth 104 scoop up residual film, weeds, and soil. Through the bridge reduction device on the residual film picking and baling machine 3, the film-lifting plate drive shaft 43 of the involute film-lifting device 4 is driven to rotate. The film-lifting plate drive shaft 43 drives the film-lifting plate 42 to rotate. The rotation direction of the film-lifting plate 42 is opposite to the rotation direction of the upper film chain plate, thereby pushing the scooped residual film and weeds onto the upper film chain plate. At the end of the upper film chain plate is a baling box. The baling box repeatedly rotates and bales the weeds and residual film conveyed by the upper film chain plate. When the baling box is full, the hydraulic cylinder drives the rear cover of the baling box, and the residual film rolls are sent out of the baling box by the rotating roller at the bottom.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
