Description

Technical Field

[0001] The utility model belongs to the technical field of ground film laying, in particular to a ground film laying device for tobacco planting. Background Art

[0002] Before tobacco is planted, it is generally necessary to use a mulch laying machine. The mulch covering cultivation technology is widely used in tobacco planting. It can effectively improve the growth environment of tobacco, maintain soil moisture before tobacco planting, control weed growth, and promote the early growth and maturity of tobacco leaves by increasing ground temperature. The mulch laying machine can lay plastic film on the tobacco planting land. The tobacco planting mulch laying machine is generally pulled by an external tractor (such as a tractor or an agricultural tricycle) to walk on the tobacco planting land and drive the mulch roll to cover the tobacco planting land. However, the current mulch laying machines generally do not have a structure to compact the stretched mulch and cover it on the planting land and to prop up the mulch to prevent wrinkles, which leads to the problem of uneven wrinkles after the mulch is laid, reducing the efficiency of mulch laying.

[0003] After searching, the existing Chinese patent publication number is: CN107810760B, a traction-type mulch film laying device for tobacco planting, including a frame-type frame, a traction plate for hanging traction equipment is fixed on the top of one end of the frame-type frame, and a walking wheel is provided at the bottom of the other end. Two mulch film mounting frames are provided at the bottom of the frame-type frame near the traction plate, and both ends of the mulch film mounting screw rod pass through the mulch film mounting frames and are fixed by nuts. A mulch film tensioning mechanism is provided at the bottom of the frame-type frame between the mulch film mounting frame and the walking wheel.

[0004] The cited patent document also has the same problem. It does not have a structure for compacting the stretched ground film and covering it on the planting ground, nor for stretching the ground film to prevent wrinkles. This leads to wrinkles and unevenness in the ground film after laying, reducing the efficiency of laying the ground film. Utility Model Content

[0007] A ground film roll is rotatably mounted at the lower part of the forward end of the film laying machine frame, and a tension-adjusting and stretching assembly for stretching the ground film to prevent wrinkles when the ground film roll is laying the ground film is provided at the middle position of the film laying machine frame on the side of the ground film roll facing away from the forward end, and the tension-adjusting and stretching assembly comprises an inverted U-shaped lifting plate installed at the lower part of the film laying machine frame, a guide roller rotatably mounted at the middle and lower part of the U-shaped lifting plate, and a tension-adjusting and stretching ground film roller installed laterally and telescopically on the outer walls of both sides of the U-shaped lifting plate;

[0008] The guide roller is sleeved on its circumference with a foam compacting sleeve for compacting the ground film to cover the different concave and convex tobacco planting plots, and the tension-adjusting ground film-opening roller is sleeved on its circumference with an anti-skid rubber sleeve for opening the ground film in opposite directions.

[0009] In this solution, the film laying machine frame is preferably in a rectangular frame structure, and a supporting top rod is welded between the middle inner walls of the film laying machine frame;

[0010] A hydraulic lifting rod is installed on the inner bottom wall of the supporting top rod, and the bottom lifting end of the hydraulic lifting rod is fixedly connected to the U-shaped lifting plate.

[0011] Preferably, positioning uprights are symmetrically welded on both sides of the top surface of the U-shaped lifting plate, and the positioning uprights penetrate the supporting top rods vertically upwards.

[0012] Preferably, the outer walls on both sides of the U-shaped lifting plate are horizontally welded with extended ear plates, and the two tension-adjusting and stretching film rollers are rotatably installed with horizontal U-shaped support plates on one side of the U-shaped lifting plate.

[0014] A limiting rod is welded on the top surface of the U-shaped support plate, and the limiting rod penetrates upward to the outer side of the I-shaped sliding block.

[0015] Preferably, in this solution, longitudinal electric slide rails are installed on the outer walls on both sides of the U-shaped lifting plate below the extended ear plate, and guide rail sliders are adapted to be slidably connected to the longitudinal electric slide rails.

[0016] Preferably, in the present solution, an electric push-pull rod is mounted on the outer wall of each guide rail slider by screws, and the push-pull free end of the electric push-pull rod is mounted on the outer wall of the U-shaped support plate by screws.

At the same time, it has friction in contact with the mulch film to prevent the mulch film soil from sliding off. The foam compaction sleeve can increase the contact pressure with the ground when the mulch film is laid, ensuring that the mulch film fits tightly to the soil, especially for uneven tobacco planting plots, which can effectively prevent air from being trapped under the mulch film to form bubbles;

[0022] The U-shaped lifting plate, with its adjustable height, allows the entire assembly to move up and down in the vertical direction to adapt to changes in terrain, thereby fitting the ground more closely and reducing hollowing of the ground film. The electric push-pull rod pushes and pulls the U-shaped support plate, and drives the I-shaped slider to slide in the positioning groove through the limit rod, thereby adjusting the tension and adjusting the lateral position of the open ground film roller to meet the needs of laying ground films of different widths.

[0033] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0034] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0035] This embodiment provides Figures 1 to 5The illustrated device is a ground film laying device for tobacco planting, comprising a film laying machine frame 1, a traction rod 2 installed at the forward end of the film laying machine frame 1 for traction by an external agricultural vehicle, support frames 3 symmetrically fixedly installed at the bottom of both sides of the film laying machine frame 1, and film laying wheels 4 respectively installed at the bottom ends of the support frames 3. The traction force of the agricultural vehicle enables the entire device to move along the tobacco planting field. The design of the traction rod 2 ensures good traction stability and steering flexibility. An L-shaped suspension rod 5 is installed opposite to each other at the lower part of the forward end of the film laying machine frame 1, and a ground film roll 6 is rotatably installed between the L-shaped suspension rods 5. Two auxiliary rods are symmetrically welded to the outer wall of one side of the film laying machine frame 1 close to the traction rod 2, and auxiliary traction wheels 7 are rotatably installed at the bottom ends of the two auxiliary rods. The bottom surfaces of both sides of the end of the film laying machine frame 1 close to the traction rod 2 are installed with outward-turning soil plows 8 for turning the soil outward on the tobacco planting ground for laying the ground film through inclined rods, and the bottom surfaces of both sides of the opposite end of the film laying machine frame 1 are installed with inward-turning soil plows 28 for turning the soil inward to cover the ground film through connecting rods 9.

[0036] In this embodiment, the outward soil plow 8 is used to loosen the soil to facilitate the laying of both sides of the ground film, and the inward soil plow 28 ensures that both sides of the ground film can be completely covered by the soil to enhance the heat preservation and moisture retention effect.

[0037] In this embodiment, in order to improve the stability and passability of the whole machine, especially in complex terrain, two auxiliary rods are symmetrically welded to the outer wall of one side of the film laying machine frame 1, and the bottom end of each auxiliary rod is equipped with an auxiliary traction wheel 7. These wheels can provide additional traction and balance support, especially when turning or going uphill, to ensure the smooth operation of the machine.

[0038] In this embodiment, a tension-adjusting stretching component 11 is provided on the side of the ground film roll 6 facing away from the forward end and in the middle position of the film laying machine frame 1 for stretching the ground film to prevent wrinkles when the ground film roll 6 is laying the ground film. The tension-adjusting stretching component 11 includes an inverted U-shaped lifting plate 12 that is lifted and installed at the lower part of the film laying machine frame 1, a guide roller 14 that is rotatably installed at the middle and lower part of the U-shaped lifting plate 12, and a tension-adjusting stretching ground film roller 20 that is laterally telescopically installed on the outer walls of both sides of the U-shaped lifting plate 12. The guide roller 14 is used to guide the ground film to unfold smoothly and reduce friction. The guide roller 14 is provided with a foam compacting sleeve 15 for compacting the ground film to cover the different concave and convex tobacco planting plots. The foam compacting sleeve 15 can increase the contact pressure with the ground when the ground film is laid, ensuring that the ground film fits tightly to the soil, especially for uneven tobacco planting plots, and can effectively avoid air stagnation under the ground film to form bubbles. The tension adjustment ground film opening roller 20 is provided with an anti-skid rubber sleeve 19 for opening the ground film in reverse and outward. The anti-skid rubber sleeve 19 helps to evenly expand the ground film and prevent wrinkles. At the same time, it has friction in contact with the ground film to prevent the ground film soil from slipping.

[0039] In this embodiment, the U-shaped lifting plate 12, through its adjustable height and inverted U-shaped design, not only provides a mounting platform for the guide roller and the tension-adjusting ground film roller, but also allows the entire assembly to move up and down in the vertical direction to adapt to changes in terrain, thereby fitting the ground more closely and reducing ground film hollowing.

[0040] In this embodiment, the guide roller 14 is located in the middle and lower part of the U-shaped lifting plate 12 and is rotatably installed through the bearing 13. The bearing 13 is embedded in the lower part of the two ends of the U-shaped lifting plate 12. Its function is to guide the ground film to pass smoothly, reduce friction and resistance, and be used in conjunction with the foam compaction sleeve to ensure that the ground film is close to the ground, especially in areas with large terrain undulations, which can effectively prevent the ground film from wrinkling or falling off the ground.

[0041] In this embodiment, the foam compaction sleeve 15 is sleeved on the outside of the guide roller. The material is light and soft, and can exert a certain pressure on the ground film to help it fit closely to the ground, especially for uneven ground. It can effectively eliminate the air under the ground film and avoid heat loss or water evaporation caused by the generation of bubbles.

[0042] In this embodiment, the tension-adjusting film-opening rollers 20 are rotatably mounted on the horizontal U-shaped support plates 24 on the outer walls on both sides of the U-shaped lifting plate 12. These tension-adjusting film-opening rollers 20 are responsible for laterally opening the film and working in coordination with the guide rollers 14 to jointly control the tension and flattening state of the film to avoid wrinkles and ensure that the film smoothly and evenly covers the tobacco-growing area.

[0043] In this embodiment, the film laying machine frame 1 has a rectangular frame structure, which ensures the stability and strength of the overall structure. A support top rod 10 is welded between the middle inner walls of the film laying machine frame 1, and a hydraulic lifting rod 16 is installed on the inner bottom wall of the support top rod 10. The bottom lifting end of the hydraulic lifting rod 16 is fixedly connected to the U-shaped lifting plate 12. Positioning vertical rods 17 are symmetrically welded on both sides of the top surface of the U-shaped lifting plate 12. The positioning vertical rods 17 vertically penetrate the support top rod 10 upward. Extension ear plates 18 are horizontally welded on the outer walls of both sides of the U-shaped lifting plate 12. Two tension-adjusting film-opening rollers 20 are rotatably installed on one side of the U-shaped lifting plate 12 with a horizontal U-shaped support plate 24.

[0044] In this embodiment, the hydraulic lifting rod 16 is connected to the U-shaped lifting plate 12, so that the entire assembly can be raised and lowered as needed to adapt to different ground film thicknesses and terrain changes, and further optimize the laying effect of the ground film.

[0045] In this embodiment, the positioning rod 17 is installed on the top of the U-shaped lifting platform 12 and passes through the supporting top rod 10 longitudinally, playing a stabilizing and positioning role, ensuring the verticality and stability of the U-shaped lifting platform 12 during the lifting or lowering process, avoiding deviation, and improving the reliability of the overall system.

[0046] In this embodiment, each side wall of the extension ear plate 18 is horizontally provided with a positioning slot 21, and an I-shaped slider 22 is slidably connected to the extension ear plate 18 and the positioning slot 21. A limiting rod 23 is welded to the top surface of the U-shaped support plate 24, and the limiting rod 23 extends upward to the outside of the I-shaped slider 22. The positioning slot 21 is designed on the side wall of the extension ear plate 18 for sliding connection with the I-shaped slider 22. This not only provides a track for the lateral position adjustment of the tension-adjusting stretched film roller 20, but also ensures the stability and accuracy during the adjustment process, which helps to accurately control the tension and laying width of the film. Through the cooperation with the limiting rod 23 and the U-shaped support plate 24, it realizes the precise positioning of the tension-adjusting stretched film roller, ensures that the tension of the film is evenly distributed, and avoids wrinkles. The limiting rod 23 is to limit the horizontal telescopic movement range of the tension-adjusting stretched film roller 20, ensure that they work stably in the positioning slot 21, and prevent the U-shaped support plate 24 from moving and tilting.

[0047] In this embodiment, longitudinal electric slide rails 25 are installed on the outer walls on both sides of the U-shaped lifting plate 12 below the extended ear plate 18, and guide rail sliders 26 are adapted to be slidably connected on the longitudinal electric slide rails 25. The outer wall of each guide rail slider 26 is installed with an electric push-pull rod 27 by screws, and the push-pull free end of the electric push-pull rod 27 is installed on the outer wall of the U-shaped support plate 24 by screws.

[0048] In this embodiment, the longitudinal electric slide rails 25 are installed below the outer walls on both sides of the U-shaped lifting plate 12, providing a track for the longitudinal movement of the guide rail slider 26. This allows the tension-adjusting mulch film roller 20 to move forward and backward on the slide rails through the drive of the electric push-pull rod 27, further refining the adjustment of the mulch film tension, adapting to different planting conditions, and improving the adaptability and efficiency of mulch film laying. In this way, the height of the tension-adjusting mulch film roller 20 can be adjusted, thereby changing the length of the two sides of the mulch film to meet the needs of different mulch film laying.

[0049] In this embodiment, the electric push-pull rod 27 pushes and pulls the U-shaped support plate 24, and drives the I-shaped slider 22 to slide in the positioning groove 21 through the limiting rod 23, thereby adjusting the tension and adjusting the lateral position of the stretched film roller 20 to meet the needs of laying films of different widths.

[0050] In this embodiment, a PLC (not shown in the figure) for controlling the opening and closing of various components is installed on the top surface of the film laying machine frame 1, and the model of the PLC should be selected according to the actual application.

[0051] Working principle:

[0052] The mulch film laying device for tobacco planting, the entire mulch film laying device is connected to an external agricultural vehicle such as a tractor through a traction rod 2. The agricultural vehicle pulls forward, driving the film laying machine frame 1 to move along the tobacco planting field, and the mulch film roll 6 rotates and unfolds as the machine moves forward. The mulch film first passes through the guide roller 14, and the foam compacting sleeve 15 covered on the guide roller compacts the mulch film to ensure that the mulch film is close to the ground and reduces air residue and wrinkles. The U-shaped lifting plate 12 in the tension adjustment expansion component 11 adjusts the height as needed to adapt to different terrains. The tension adjustment expansion mulch film roller 20 is covered with an anti-slip rubber sleeve 19. Through the movement of the electric push-pull rod 27 and the guide rail slider 26 on the longitudinal electric slide rail 25, and the lateral adjustment of the I-shaped slider 22 in the positioning groove 21, precise tension control of the mulch film is achieved to ensure that the mulch film is neither too tight nor too loose, and maintains an ideal straight state;

[0053] The tension-adjusting film-opening roller 20 is responsible for horizontally opening the film and works in conjunction with the guide roller 14 to control the tension and flattening state of the film to avoid wrinkles and ensure that the film is smoothly and evenly covered on the tobacco planting area;

[0054] As the film laying machine moves forward, the outward-turning soil plow 8 loosens the soil at the film laying position first, providing a flat foundation for laying the film and avoiding damage caused by hard objects under the film. As the film is laid, the inward-turning soil plow 28 turns the soil inward and covers the film to complete the sealing of the film, effectively preventing wind erosion and water evaporation, while inhibiting the growth of weeds.
