Description

Technical Field

[0001] This invention relates to the field of vegetable cultivation technology, and in particular to a vegetable cultivation film pressing device. Background Technology

[0002] Vegetables are an essential part of people's daily diet. They provide the human body with a variety of essential vitamins and minerals. In some plains and hilly areas, vegetables such as potatoes, tomatoes, peanuts, peppers, corn, and cucumbers are often grown with plastic film. The plastic film can increase the soil temperature and retain moisture. Covering the soil with plastic film can reduce surface water evaporation and lower the relative humidity of the air, thereby promoting plant growth. At the same time, plastic film can help control the occurrence of diseases. Therefore, a film pressing device is used to cover the planting surface with film.

[0003] The existing film pressing devices mostly have a fixed pressing force, which cannot be adjusted according to the film material, vegetable variety and soil conditions. Different types of vegetables (such as leafy vegetables, solanaceous vegetables and root vegetables) have different requirements for the tightness of the film covering. A fixed pressing force can easily lead to the film being pressed too tightly and damaged, or the film being blown away by the wind due to insufficient pressing. In addition, it has poor adaptability to uneven terrain. Since the soil in the field often has undulations, the rigidly connected film pressing mechanism is difficult to fit the ground, which can easily cause some areas to be not pressed properly, affecting the film covering effect. Summary of the Invention

[0004] The purpose of this invention is to provide a vegetable planting film pressing device that can not only adjust the film pressing force according to the type of vegetable being planted and the material of the film, but also properly level the soil during film pressing so that the film can adhere to the soil surface.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A vegetable planting film pressing device includes a traveling vehicle. Grooves are provided on the left and right sides of the front end of the inner wall of the traveling vehicle and at the front ends of the left and right sides of the inner wall. The lower end of the traveling vehicle is provided with a plurality of guide rails that cooperate with and communicate with the grooves. The inner wall of the guide rails is slidably connected to a slide frame that can slide up and down. The bottom of the corresponding slide rails on the left and right sides of the traveling vehicle and the lower end of the slide frame are each fitted with a first electric push rod. The left and right sides of the front end of the bottom of the slide frame are provided with plow heads. The lower end of the inner wall of each plow head is provided with a scraper that slopes outward from back to front. The bottom of the slide frame, behind the plow head, is provided with a soil loosening component and an L-shaped, elastic soil scraping plate. The bottom of the traveling vehicle is provided with a guide component behind the slide to facilitate the flattening of the mulch film. Behind the guide component is a height-adjustable film pressing component. The left and right sides of the rear end of the inner wall of the traveling vehicle are each equipped with a second electric push rod. A mounting bracket is provided between the upper ends of the two second electric push rods. The front and rear ends of the left and right sides of the upper end of the mounting bracket are provided with guide holes. The front and rear ends of the left and right sides of the rear end of the inner wall of the traveling vehicle are each provided with a guide rod passing through the guide hole. On both sides of the mounting frame, at positions on the same axis as the plow head, a pressing wheel, a soil covering plate, and a pressing wheel are installed sequentially from front to back. The height of the pressing wheel is greater than that of the pressing wheel. The front end of each soil covering plate is inclined outward. Each pressing wheel has a soil-raising wheel fixedly installed and expanding outward on its outer wall. On both sides of the inner wall of the mounting frame, between the pressing wheel and the soil covering plate, a conveying mechanism for conveying soil upward is vertically installed. On both sides of the inner wall of the mounting frame, behind the upper end of the corresponding conveying mechanism, a soil guide groove is provided inward and inclined downward. The mounting frame is equipped with a drive assembly for driving the two conveying mechanisms. Uprights are arranged opposite each other on the left and right sides of the upper front end of the traveling vehicle. The inner edge of the upper end of each upright has a fixing groove with an arc-shaped lower end. A support rod for installing the mulch film is detachably connected between the two fixing grooves. Several rollers are rotatably connected to the inner wall of the arc end of each fixing groove. Limit sleeves are detachably connected to the left and right sides of the outer wall of the support rod. The upper end of the outer wall of each limit sleeve is threaded with a fixing bolt extending into it.

[0006] By adopting the above technical solution, when using the device, first move it to the soil surface that needs to be covered with film. Then, remove the support rod from the upright, put the film on the support rod, and then place it in the fixing groove. Next, the worker will pass the free end of the film around the guide component and pull it out of the rear end of the walking vehicle. Then, the worker will lay the free end of the film flat and place it on the soil surface. Then, the film will be initially fixed with soil. After the operation is completed, the first electric push rod will be activated, shortening a certain length to drive the slide frame downward and let the plow head extend into the soil. At the same time, the loosening component and the digging board will both be in contact with the soil surface. Then, adjust the height of the film pressing component so that its lower end is in contact with the film and the film is tightly attached to the soil surface. Next, the second electric push rod is shortened to a certain length, allowing the pressing roller, soil covering plate, and soil pressing roller on the mounting frame to contact the soil surface and press and fix the free end of the mulch film. Then, the traveling vehicle can move forward. At the same time, the soil loosening component and drive component work. The soil loosening component can crush the larger soil clods on the soil surface, and then the soil leveling plate is used to level the soil surface. The drive component drives the two conveying mechanisms. As the traveling vehicle moves, not only can the mulch film laying work be completed, but the soil covering plate can also gather the soil and allow some soil to be transported to the middle of the mulch film through the conveying mechanism and soil guide trough to compact it. The soil pressing roller and soil covering roller can compact the soil on both sides of the mulch film, thereby completing the mulch film pressing work.

[0007] A further embodiment of the present invention is that the vehicle includes a support frame, a plurality of hub motors installed at the bottom of the support frame and arranged in an array, batteries respectively installed at the rear of the upper end of the support frame, a control cabinet installed at the front end of the upper end of the support frame, and handrails installed between the left and right sides of the upper end of the support frame.

[0008] A further configuration of the present invention is as follows: the soil loosening component includes a fixed shaft, a plurality of soil loosening rods distributed at equal intervals on the outer wall of the fixed shaft, a first pulley installed at one end of the outer wall of the fixed shaft, a first drive motor installed on one side of the outer wall of the fixed shaft, a second pulley installed on the outer wall of the power output shaft of the first drive motor, and a first belt disposed between the first pulley and the second pulley.

[0009] A further configuration of the present invention is as follows: the drive assembly includes a connecting shaft disposed between the upper ends of the two conveying mechanisms, a third pulley mounted on one side of the outer wall of the connecting shaft, a second drive motor mounted on one side of the upper end of the mounting bracket, a fourth pulley mounted on the outer wall of the power output shaft of the second drive motor, and a second belt disposed between the third pulley and the fourth pulley.

[0010] By adopting the above technical solution, larger soil clods on the soil surface can be crushed before mulching, which facilitates mulching and avoids damaging the mulch film.

[0011] A further feature of the present invention is that: push blocks are provided on both the left and right sides of the bottom of the digging plate, and push blocks are provided on the same axis as the plow head; and a plurality of digging strips are provided at equal intervals between the two push blocks on the bottom of the digging plate.

[0012] By adopting the above technical solution, the pusher can clear the soil that falls into the trench after the plow head opens, allowing both ends of the mulch film to be located in the trench, which facilitates the operation of the pressing roller and improves the stability of compaction at both ends of the mulch film. Meanwhile, the soil strip can open a certain trench on the soil surface, allowing the soil on the soil surface to have a certain amount of mobility when the pressing film assembly is pressing the film, thereby improving the tightness between the mulch film and the soil surface.

[0013] A further embodiment of the present invention is that the guiding assembly includes a guide frame, a first guide roller rotatably connected between the left and right sides of the inner wall of the guide frame, and two second guide rollers rotatably connected between the left and right sides below the rear end of the guide frame and arranged opposite to each other.

[0014] A further feature of the present invention is that the upper ends of the left and right sides of the inner wall of the guide frame are inclined downward and inwardly provided with guide grooves for gathering the edge of the mulch film, and the two guide grooves are arranged in a V-shape.

[0015] By adopting the above technical solution, the edges of the mulch film can be folded and gathered during the laying process. This not only prevents the pressing roller from crushing the film, but also allows for a certain amount of expansion and contraction when the mulch film is pressed into the trench, avoiding pulling on the mulch film on the soil surface. It also allows the edges of the mulch film to be covered and pressed tightly by the soil as much as possible.

[0016] A further configuration of the present invention is as follows: the film pressing assembly includes a fixed frame, first sliding holes on the left and right sides of the upper end of the fixed frame, a connecting frame slidably connected to the first sliding holes, a threaded hole in the middle position of the upper end of the fixed frame, a handwheel rotatably connected to the upper end of the fixed frame and communicating with the threaded hole, a threaded rod disposed on the upper end of the connecting frame and passing through the threaded hole and the handwheel and being threadedly connected to them, second sliding holes respectively on the left and right sides of the upper end of the connecting frame, a sliding rod slidably connected to the second sliding hole and extending out of its lower end, a film pressing roller disposed between the lower ends of the two sliding rods, and a return spring respectively disposed between the lower end of the connecting frame and the upper end of the outer wall of the film pressing roller and sleeved on the corresponding sliding rod.

[0017] By adopting the above technical solution, the pressure applied to the mulch film by the pressing roller can be adjusted according to the soil moisture level. At the same time, the return spring can also allow the pressing roller to adaptively adjust according to the soil moisture level, thereby avoiding the fixation of the pressing force.

[0018] A further embodiment of the present invention is that the conveying mechanism includes a positioning frame, a rotating shaft rotatably connected between the upper and lower ends of the positioning frame, a conveyor belt disposed on the outer wall of the two rotating shafts, and a plurality of guide plates distributed at equal intervals on the outer wall of the conveyor belt.

[0019] In summary, the present invention has the following beneficial effects: Firstly, this invention can not only adjust the film-forming force according to the type of vegetables being planted and the material of the mulch film, but also properly level the soil during the pressing process, so that the mulch film can adhere to the soil surface. Secondly, the guide component and guide groove of the present invention can not only flatten the mulch film, but also fold and gather its edges when laying the mulch film. This not only prevents the pressing roller from crushing it, but also allows the mulch film to have a certain amount of room for expansion and contraction when pressing it into the trench, avoiding pulling on the mulch film on the soil surface, and also allows the edges of the mulch film to be covered and pressed tightly by the soil as much as possible. Thirdly, the pressing assembly of the present invention can adjust the pressure applied to the mulch film by the pressing roller according to the soil moisture condition. At the same time, the return spring can also make the pressing roller adaptively adjust according to the soil moisture level, thereby avoiding the fixation of the pressing force.

[0030] A second electric push rod 5 is installed on both the left and right sides of the rear end of the inner wall of the traveling vehicle 1. A mounting frame 51 is provided between the upper ends of the two second electric push rods 5. A guide hole 52 is provided at the front and rear ends of the left and right sides of the upper end of the mounting frame 51. A guide rod 53 passing through the guide hole 52 is provided at the front and rear ends of the left and right sides of the rear end of the inner wall of the traveling vehicle 1. A pressing wheel 54, a soil covering plate 55, and a pressing wheel 56 are installed sequentially from front to back on the left and right sides of the mounting frame 51 at the same axis as the plow head 24. The height of the pressing wheel 56 inside the mounting frame 51 is greater than the height of the pressing wheel 54. The front end of each soil covering plate 55 is inclined outward. A soil-raising wheel 57 is fixedly installed and expands outward on the outer wall of each pressing wheel 56. A conveying mechanism 6 for conveying soil upward is vertically installed on the left and right sides of the inner wall of the mounting frame 51 between the pressing wheel 54 and the soil covering plate 55.

[0031] The conveying mechanism 6 includes a positioning frame 601, rotating shafts 602 rotatably connected between the upper and lower ends of the positioning frame 601, conveyor belts 603 fitted on the outer walls of the two rotating shafts 602, and several guide plates 604 evenly distributed on the outer walls of the conveyor belts 603. Guide grooves 67 are provided on the left and right sides of the inner wall of the mounting frame 51, facing inward and inclined downward at the rear of the upper end of the corresponding conveying mechanism 6. The mounting frame 51 is provided with a drive assembly 61 for driving the two conveying mechanisms 6. The drive assembly 61 includes a connecting shaft 62 fitted between the corresponding rotating shafts 602 at the upper end of the two conveying mechanisms 6, a third pulley 63 installed on one side of the outer wall of the connecting shaft 62, a second drive motor 64 installed on one side of the upper end of the mounting frame 51, a fourth pulley 65 installed on the outer wall of the power output shaft of the second drive motor 64, and a second belt 66 fitted between the third pulley 63 and the fourth pulley 65.

[0032] On the left and right sides of the upper front end of the traveling vehicle 1, there is a vertical pole 7. Each vertical pole 7 has a fixing groove 71 with an arc-shaped lower end on the inner edge of its upper end. A support rod 73 for installing mulch film is detachably connected between two fixing grooves 71. Several rollers 72 are rotatably connected to the inner wall of the arc end of each fixing groove 71. A limiting sleeve 74 is detachably connected to the left and right sides of the outer wall of the support rod 73. A fixing bolt 75 extending into the upper end of the outer wall of each limiting sleeve 74 is threadedly connected. The hub motor 12, the first drive motor 264, the second drive motor 64, the first electric push rod 23 and the second electric push rod 5 are all electrically connected to the control cabinet 14.

[0033] Usage: When using, first move the device to the soil surface that needs to be covered with film. Then, remove the support rod 73 from the upright 7, put the film on the support rod 73, and then place it in the fixing groove 71. Then, adjust the position of the limiting sleeve 74 so that the film is in the center position on the support rod 73, and then turn the fixing bolt 75 to fix it. Next, the operator operates the control cabinet 14, which is powered by the storage battery 13 to make the first electric push rod 23 work, shorten a certain length, and drive the slide 22 to slide down along the guide groove 34 so that the plow head 24 extends into the soil. Then, the hub motor 12 works to drive the support frame 11 to move forward a certain distance. The plow head 24 processes the soil surface to open two trenches. Then, the slide 22 returns to the initial state and the traveling vehicle 1 returns to its original position.

[0034] Next, the workers will pass the free end of the mulch film around the guide assembly 33, so that it contacts the front and back of the two first guide rollers 332 respectively, and place both ends of the mulch film in the guide grooves 34 of the guide frame 331 respectively. Then, they will pass it between the two second guide rollers 333 and pull the free end of the mulch film out of the rear end of the support frame 11. Then, the workers will lay the free end of the mulch film flat and place it on the soil surface. Then, they will use soil to initially fix the mulch film. After the operation is completed, the second electric push rod 5 will shorten a certain length, driving the installation frame 51 to move downward along the guide rod 53, so that the pressing roller 54 on the installation frame 51 contacts the edge of the mulch film and presses it into the trench. At the same time, the soil covering plate 55 will be located at the outer edge of the trench, thereby achieving the pressing and fixing of the free end of the mulch film.

[0035] Next, adjust the height of the film pressing assembly 4, rotate the first wheel on the fixed frame 401 to make the threaded rod 406 drive the support rod 73 to slide down along the first sliding hole 402, and make the film pressing roller 409 contact the mulch film so that the mulch film is tightly attached to the soil moisture surface. Then, make the soil loosening assembly 26 and the soil scraping plate 3 contact the soil moisture surface again, and then the traveling vehicle 1 can be moved forward. At the same time, make the soil loosening assembly 26 and the drive assembly 61 work. The first drive motor 264 drives the second pulley 265 to rotate and drives the first pulley 263 and the fixed shaft 261 to rotate through the first belt 266. The larger soil clods on the soil moisture surface are crushed by the soil loosening rod 262.

[0036] Then, the soil surface is leveled by the excavator 3, and the second drive motor 64 drives the fourth pulley 65 to rotate, which in turn drives the third pulley 63 and the connecting shaft 62 to rotate via the second belt 66, thereby enabling the two conveying mechanisms 6 to work. As the traveling vehicle 1 moves, the covering plate 55 will gather the soil at the edge of the trench and push it towards the conveying mechanism 6, so that some soil can be transported to the middle of the mulch film through the conveying mechanism 6 and the guide trough 67 to be compacted. The pressing wheel 56 and the soil-covering wheel 57 can compact the soil on both sides of the mulch film, thereby completing the mulch film compaction work. The soil-covering wheel 57 can not only make the two sides of the mulch film surface into a slope, but also further gather the soil during compaction, which makes it easier to improve the tightness of the mulch film compaction.
