Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural machinery, and particularly relates to a full-automatic integrated machine for laying pipes, laying films and precisely sowing vegetables on the film. Background Art

[0002] Vegetables are one of the essential foods in people's daily diet. Vegetables can provide various vitamins and minerals and other nutrients necessary for the human body. As an important achievement of modern agricultural mechanization, the full-automatic integrated machine for laying pipes, laying films and precisely sowing vegetables on the film integrates three core functions of laying pipes, laying films and precise sowing, and is designed specifically for the efficient planting of vegetables and other crops. In the process of vegetable planting, laying pipes and laying films is a crucial link, and its main purpose is to increase soil temperature, maintain soil moisture, inhibit weed growth, and provide a good microenvironment for vegetable growth.

[0003] At present, the existing full-automatic integrated machine for laying pipes, laying films and precisely sowing vegetables on the film has improved the automation level of vegetable planting to a certain extent, but there are still many deficiencies. First, in the process of laying the film, it is difficult to precisely control the adhesion degree between the plastic film and the soil. If it is too tight, the plastic film is easily torn, affecting the quality of film laying. If it is too loose, it cannot effectively prevent wind from uncovering, and the heat preservation and moisture preservation effects are greatly reduced. Second, for the different requirements of plant spacing and row spacing for different crops, the existing equipment needs to frequently adjust mechanical parameters, which is cumbersome to operate and has low efficiency. Especially when operating on slopes, due to the complex terrain, it is even more difficult to ensure the effects of laying pipes and laying films, and problems such as drip irrigation pipe dislocation and plastic film wrinkles often occur, seriously affecting the yield and quality of vegetable planting. Therefore, there are deficiencies and it cannot meet the user's usage requirements. Therefore, it is necessary to further improve.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a full-automatic integrated machine for laying pipes, laying films and precisely sowing vegetables on the film is provided, in order to achieve a more practical value purpose. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a full-automatic integrated machine for laying pipes, laying films and precisely sowing vegetables on the film, which is achieved by the following specific technical means:

[0006] The full-automatic integrated machine for laying pipes, laying films and precisely sowing vegetables on the film includes a frame and a fixing frame, a sowing mechanism arranged on the frame, a pipe laying component and a film laying component arranged on the fixing frame, a film pressing mechanism arranged on the fixing frame, and a soil covering component arranged on the fixing frame;

[0007] The sowing mechanism is used for sowing vegetable seeds, the pipe laying component is used for laying drip irrigation pipes, and the film laying component is used for laying plastic films;

[0008] The film pressing mechanism includes a fixing plate fixedly assembled on the fixing frame. A film pressing assembly is fixedly assembled at the bottom of the fixing plate. A film pressing plate is connected to the bottom of the film pressing assembly. A number of pressing components for pressing and fitting the plastic film against the ground are fixedly assembled at the bottom of the film pressing plate. The number of pressing components is arranged in two rows and is staggered with each other. By pushing the film pressing plate and the pressing components through the film pressing assembly to press the plastic film, the plastic film can be closely attached to the soil surface. The pressing components can adaptively expand and contract to press the plastic film according to the terrain.

[0009] As a further description of the above technical solution: Through the coordinated action among the seeding mechanism, the pipe laying assembly, the film laying assembly and the film pressing mechanism, the automation and integration of operations such as seeding, pipe laying and film laying are realized, greatly reducing the production cost and improving the economic benefits of agricultural production. At the same time, the film pressing plate and the film pressing wheels on the pressing components apply continuous and uniform pressure to the plastic film. Through this setting, not only is it ensured that the plastic film can be closely attached to the soil surface, but also the situation of the plastic film being lifted by the wind force is avoided. And the film pressing wheels can adaptively press according to the changes of the soil terrain, avoiding the problems of local over-tightening and tearing of the plastic film and improving the laying effect of the plastic film.

[0012] As a further description of the above technical solution: By using its acute angle and weight, the soil turning plate inserts into the soil to form a seed ditch with appropriate depth and uniform width. At the same time, the seeds in the seeding box fall into the seed ditch through the seeding opening at the bottom of the seeding pipe, realizing the seeding of the seeds. Immediately afterwards, the covering roller rolls and turns the soil to cover the seeds in the seed ditch, thus completing the automatic seeding process of the seeds.

[0015] Further, the film laying assembly includes a first film laying frame and a second film laying frame. The first film laying frame is fixedly assembled on the fixed frame. A number of limit holes are provided on both the first film laying frame and the second film laying frame. Limit bolts are screwed through the limit holes.

[0016] As a further description of the above technical solution: The arrangement of the limit bolts and the limit holes is beneficial to the installation and disassembly of the second film laying frame, facilitating the replacement of the film roll on the second film laying frame and further improving its applicability.

[0017] Further, the film laying assembly further includes a film laying roller movably assembled on the second film laying frame. A film roll for laying the plastic film is sleeved on the film laying roller. A guiding roller for guiding and orienting the plastic film on the film roll is rotatably installed on the first film laying frame.

[0018] As a further description of the above technical solution: The plastic film on the film roll is smoothly laid on the soil surface under the guidance of the guiding roller. And through the laying of the plastic film, the evaporation of soil moisture can be reduced, the ground temperature can be enhanced, and the early maturity and high yield of vegetables can be promoted.

[0019] Further, the film pressing assembly includes a film pressing seat fixedly assembled at the bottom of the fixed plate. A guiding rod is fixedly installed on the film pressing seat.

A second film pressing rod is movably connected between the guiding block and the first film pressing rod.

[0021] As a further description of the above technical solution: Through the elastic force of the film pressing spring in the film pressing assembly, the film pressing plate and the film pressing wheel on the pressing component apply continuous and uniform pressure to the plastic film. Through this setting, not only is it ensured that the plastic film can be closely attached to the soil surface, but also the situation that the plastic film is lifted by the wind force is avoided.

[0022] Further, the pressing assembly includes a fixed sleeve fixedly assembled at the bottom of the film pressing plate, and an inner cavity is formed inside the fixed sleeve. A pressing rod is slidably installed at the bottom of the fixed sleeve. A pressing frame is fixedly installed at the lower end of the pressing rod, and a film pressing wheel for tightly pressing the ground film is rotatably installed on the pressing frame.

[0023] An activity plate is slidably installed in the inner cavity of the fixed sleeve. The upper end of the pressing rod extends into the inner cavity of the fixed sleeve and is fixedly connected to the activity plate. A pressing spring is fixedly connected between the upper side of the activity plate and the top wall of the inner cavity of the fixed sleeve.

[0024] As a further description of the above technical solution: By pushing the activity plate with the pressing rod to squeeze the pressing spring, automatic adaptive adjustment is realized. This mechanism not only ensures the stable laying of the drip irrigation pipe but also avoids the tearing problem of the ground film caused by local over-tightening.

[0025] Further, a plurality of limiting chutes are formed on the inner cavity wall of the fixed sleeve. A plurality of limiting sliders are fixedly installed on the outer periphery of the activity plate, and the limiting sliders are located in the limiting chutes.

[0028] As a further description of the above technical solution: The soil covering plate drives the soil to be spread on both sides of the ground film, thereby automatically pressing the edges of the ground film on both sides. Through this setting, not only the stability of the ground film is enhanced, but also the problem that the ground film is loosened due to the action of wind is avoided, and further the film covering effect of the ground film on the soil is better.

[0029] Further, a traction frame is fixedly assembled on the left side of the frame, and the traction frame is connected and assembled with a tractor.

[0030] As a further description of the above technical solution: The setting of the traction frame is beneficial to the connection and assembly with an external tractor.

[0031] To sum up, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0032] 1. Through the coordinated action among the seeding mechanism, pipe-laying component, film-laying component and film-pressing mechanism, this fully automatic integrated machine for precision seeding, pipe-laying and film-laying on vegetables on the film realizes the automation and integration of operations such as seeding, pipe-laying and film-laying. At the same time, the film-pressing wheel on the pressing component applies continuous and uniform pressure to the plastic film, and the continuous and uniform pressure makes the plastic film laid flat, reducing the generation of wrinkles and bubbles, improving the film-laying quality. Through this setting, not only is it ensured that the plastic film can closely adhere to the soil surface, but also the situation where the plastic film is lifted by the wind force is avoided. Moreover, the film-pressing wheel can adaptively press according to the changes in the soil terrain, avoiding the problems of local over-tightening and tearing of the plastic film, improving the laying effect of the plastic film. At the same time, the two rows of staggered film-pressing wheels can apply pressure to the plastic film from different directions, and can more effectively flatten the plastic film, making the plastic film closely adhere to the ground in all directions. And the staggered film-pressing wheels can supplement the pressure with each other, making the plastic film in the entire laying area receive more uniform pressure, avoiding the damage of the plastic film or uneven pressure on the drip irrigation pipe caused by uneven local pressure.

[0033] 2. Through the coordinated action among the pipe-laying component, film-laying component and film-pressing mechanism, this fully automatic integrated machine for precision seeding, pipe-laying and film-laying on vegetables on the film realizes the automatic adaptive adjustment of the film-pressing wheel. This mechanism not only ensures the stable laying of the drip irrigation pipe, but also avoids the tearing problem of the plastic film caused by local over-tightening. At the same time, the two rows of staggered film-pressing wheels can form a more stable support and guiding structure, which can better fix the position of the drip irrigation pipe and prevent its lateral and longitudinal displacement misalignment during the laying process due to terrain changes, further improving the laying effect of the drip irrigation pipe. At the same time, when encountering terrain changes, the staggered film-pressing wheels can cooperate with each other. On the one hand, they can conduct more accurate guiding for the drip irrigation pipe to ensure that it always remains on the correct laying route. On the other hand, the staggered film-pressing wheels increase the contact points and support points between the equipment and the ground, improving the stability of the equipment during operation and reducing the film-laying and pipe-laying errors caused by equipment shaking.

[0034] 3. Through the coordinated work among the soil-turning plate, seeding pipe and soil-covering roller, this fully automatic integrated machine for precision seeding, pipe-laying and film-laying on vegetables on the film realizes the automatic seeding of seeds, greatly improving the seeding efficiency and accuracy and reducing the labor intensity of manual work.

[0035] 4. Through the coordinated action among the adjusting slide rail, adjusting slider and pipe-laying shell, by setting the adjusting slide rail and adjusting slider, the laying row spacing of the drip irrigation pipe can be conveniently adjusted to meet the different irrigation requirements of different crops, so as to adapt to the irrigation needs of different crops and provide good irrigation conditions for the growth of crops.

A drip irrigation pipe for drip-irrigating vegetable seeds is assembled inside the pipe-laying shell 34, and a number of drip irrigation holes are opened on the drip irrigation pipe; during the seeding operation, the pipe-laying shell 34 starts to release and lay the drip irrigation pipe. The drip irrigation pipe is released outwards through the pipe-laying shell 34 and is evenly laid on the soil, providing convenience for subsequent irrigation operations. Through pipe-laying, irrigation and fertilization can be carried out conveniently, effectively managing soil moisture and nutrients.

[0060] Please refer to Figures 4 to 7 , the film-laying assembly 40 includes a first film-laying frame 41 and a second film-laying frame 42. The first film-laying frame 41 is fixedly assembled on the fixed frame 11. A number of limit holes 43 are opened on both the first film-laying frame 41 and the second film-laying frame 42. A limit bolt 44 is screwed through the limit hole 43. The installation and disassembly of the first film-laying frame 41 and the second film-laying frame 42 are realized by screwing the limit bolt 44 with the limit hole 43; the setting of the limit bolt 44 and the limit hole 43 is beneficial to the installation and disassembly of the second film-laying frame 42, facilitating the replacement of the film-covering roll 46 on the second film-laying frame 42.

[0062] Please refer to Figures 8 to 9, the film pressing assembly 52 includes a film pressing seat 521 fixedly assembled at the bottom of the fixing plate 51. A guide rod 522 is fixedly installed on the film pressing seat 521. A guide block 523 is slidably installed on the guide rod 522. A film pressing spring 524 is sleeved on the guide rod 522, and the film pressing spring 524 is located between the inner wall of the film pressing seat 521 and the guide block 523.

A second film pressing rod 526 is movably connected between the guide block 523 and the first film pressing rod 525. In order to ensure the close fit between the plastic film and the soil, the film pressing spring 524 in the film pressing assembly 52 acts through elastic force, and uses the first film pressing rod 525, the second film pressing rod 526 and the film pressing member 527 to push the film pressing plate 53 and the pressing assembly 54, so that the film pressing wheels 544 on the film pressing plate 53 and the pressing assembly 54 apply a continuous and uniform pressure to the plastic film. The continuous and uniform pressure makes the plastic film laid flat, reduces wrinkles and bubbles, and improves the film laying quality. Through this setting, it not only ensures that the plastic film can be closely attached to the soil surface, but also avoids the situation that the plastic film is lifted by the wind force.

[0063] Please refer to Figures 8 to 10The pressing assembly 54 includes a fixed sleeve 541 fixedly assembled at the bottom of the film pressing plate 53, and an inner cavity is opened inside the fixed sleeve 541, a pressing rod 542 is slidably installed at the bottom of the fixed sleeve 541, and a pressing frame 543 is fixedly installed at the lower end of the pressing rod 542, and a film pressing wheel 544 is rotatably installed on the pressing frame 543 to tightly press the ground film; a movable plate 545 is slidably installed in the inner cavity of the fixed sleeve 541, and the upper end of the pressing rod 542 extends into the inner cavity of the fixed sleeve 541 and is fixedly connected to the movable plate 545, and a pressing spring 546 is fixedly connected between the upper side of the movable plate 545 and the top wall of the inner cavity of the fixed sleeve 541; when the film pressing wheel 544 contacts the drip irrigation pipe across the ground film, based on the pressure sensing mechanism, the film pressing wheel 544 will automatically move up, and push the movable plate 545 to squeeze the pressing spring 546 through the pressing rod 542, so as to realize automatic adaptive adjustment This mechanism not only ensures the stable laying of the drip irrigation pipe, but also avoids the tearing problem caused by local over-tightening of the ground film; and by arranging the film pressing wheels 544 into two staggered rows, the two rows of staggered film pressing wheels 544 can apply pressure to the ground film from different directions, so that the ground film can fit tightly to the ground in all directions, and the staggered film pressing wheels 544 can supplement each other's pressure, so that the ground film in the entire laying area is subjected to more uniform pressure, avoiding damage to the ground film or uneven pressure on the drip irrigation pipe due to local uneven pressure; and when operating in complex terrain, the staggered film pressing wheels 544 can adapt to changes in terrain more flexibly. When the film pressing wheels 544 on one side encounter a raised terrain, the staggered film pressing wheels 544 on the other side can play a role in supplementing support and adjusting pressure, so that the ground film can still fit tightly to the ground, avoiding the ground film from being lifted or the drip irrigation pipe from being misplaced due to local terrain changes.

[0064] See also Figure 10 A plurality of limiting grooves 5411 are provided on the inner cavity wall of the fixed sleeve 541, and a plurality of limiting sliders 5451 are fixedly installed on the outer periphery of the movable plate 545, and the limiting sliders 5451 are located in the limiting grooves 5411; the limiting sliders 5451 are driven to move synchronously while the movable plate 545 moves up and down, and the limiting sliders 5451 are driven to slide in the limiting grooves 5411. This arrangement can effectively prevent the pressure rod 542 and the film pressing wheel 544 from shifting.

[0065] See also Figure 1 , Figure 4, the soil covering component 60 includes a soil covering frame 61 fixedly assembled on the fixing frame 11. A detachable soil covering rod 62 is assembled on the soil covering frame 61. A soil covering plate 63 for covering the soil on both sides of the plastic film is fixedly assembled at the bottom of the soil covering rod 62. The moving frame 10 drives the soil covering rod 62 and the soil covering plate 63 to move synchronously. The soil covering plate 63 drives the soil to be spread to both sides of the plastic film, thereby automatically pressing the edges of both sides of the plastic film. Through this setting, not only the stability of the plastic film is enhanced, but also the problem that the plastic film is loosened due to the action of wind is avoided, and further the film laying effect of the plastic film on the soil is better.

[0066] The specific usage mode and function of this embodiment:

[0067] Working principle: When in use, first, a tractor outside needs to be firmly connected to the towing frame 12 on the frame 10 to form a stable and reliable mobile operation platform. Subsequently, an appropriate amount of seeds to be sown are loaded into the sowing box 22 to ensure that the seeds can be continuously and evenly supplied during the sowing process. Then, by pulling one end of the drip irrigation pipe and the plastic film and fixing and positioning it, the tractor then pulls the frame 10 to move stably in the preset soil area, and this device starts to perform its comprehensive sowing, pipe laying, and film laying operations. During the sowing process, the soil turning plate 24 on the sowing mechanism 20 inserts into the soil by its own acute angle and weight to form a seed trench with appropriate depth and uniform width. At the same time, the seeds in the sowing box 22 fall into the seed trench through the sowing opening at the bottom of the sowing pipe 23, realizing the sowing of the seeds. Immediately afterwards, the soil covering roller 25 rolls and turns the soil to cover the seeds in the seed trench, thus completing the automatic sowing process of the seeds;

[0068] During the sowing operation, as the frame 10 moves, under the traction force when the frame 10 moves, the pipe laying shell 34 starts to lay the drip irrigation pipe. The drip irrigation pipe is released from the inside of the pipe laying shell 34 and is evenly laid on the soil, providing convenience for subsequent irrigation operations. Through pipe laying, irrigation and fertilization can be conveniently carried out, effectively managing soil moisture and nutrients. Moreover, the design of the pipe laying shell 34 not only ensures the stable laying of the drip irrigation pipe, but also realizes the flexible adjustment of the laying row spacing of the drip irrigation pipe by adjusting the slide rail 31 and the adjusting slider 32, so as to effectively adjust the laying position of the drip irrigation pipe, meeting the different irrigation requirements of different crops to adapt to the irrigation needs of different crops;

[0069] In addition, during the movement of the frame 10, the film laying assembly 40 also starts to work. At the same time, under the traction force during the movement of the frame 10, the plastic film on the film roll 46 is driven to be smoothly laid on the soil surface under the guidance of the guiding roller 47. And through the laying of the plastic film, the evaporation of soil moisture can be reduced, the ground temperature can be increased, and the early maturity and high yield of vegetables can be promoted. To ensure the tight fit between the plastic film and the soil, the pressing film spring 524 in the pressing film assembly 52 uses elastic force to push the pressing film plate 53 and the pressing component 54 through the first pressing film rod 525, the second pressing film rod 526 and the pressing film member 527, so that the pressing film wheels 544 on the pressing film plate 53 and the pressing component 54 apply continuous and uniform pressure to the plastic film. Through this setting, not only is it ensured that the plastic film can be tightly attached to the soil surface, but also the situation where the plastic film is lifted by the wind force is avoided. And the continuous and uniform pressure makes the plastic film laid flat, reducing wrinkles and bubbles, improving the film laying quality. The stable pressure also helps the drip irrigation pipe to be laid in a straight line, improving the pipe laying quality and reducing problems such as uneven irrigation caused by uneven laying in the later stage. And by arranging the pressing film wheels 544 in two staggered rows, the two rows of staggered pressing film wheels 544 can apply pressure to the plastic film from different directions, so that the plastic film can be tightly attached to the ground in all directions. And the staggered pressing film wheels 544 can complement each other in pressure, making the plastic film in the entire laying area receive more uniform pressure, avoiding damage to the plastic film or uneven pressure on the drip irrigation pipe caused by uneven local pressure. At the same time, the moving frame 10 drives the soil covering rod 62 and the soil covering plate 63 to move synchronously, and the soil covering plate 63 drives the soil to be spread to both sides of the plastic film, thereby automatically pressing the edges of the plastic film. And through this setting, not only the stability of the plastic film is enhanced, but also the problem that the plastic film is loosened by the wind force is avoided, and thus the film laying effect of the plastic film on the soil is better.

[0070] During the film pressing process, when the film pressing wheel 544 contacts the drip irrigation pipe through the ground film, based on the pressure sensing mechanism, the film pressing wheel 544 will automatically move up, and push the movable plate 545 to squeeze the pressure spring 546 through the pressure rod 542, so as to realize automatic adaptive adjustment. This mechanism not only ensures the stable laying of the drip irrigation pipe, but also avoids the tearing problem of the ground film caused by local over-tightening. At the same time, the adjacent film pressing wheels 544 on both sides of the upward film pressing wheel 544 will automatically guide the drip irrigation pipe, and the two rows of staggered film pressing wheels 544 form a more stable support and guiding structure. The structure can better fix the position of the drip irrigation pipe and prevent it from being displaced horizontally and vertically due to terrain changes during the laying process, thereby further improving the laying effect of the drip irrigation pipe. At the same time, when encountering terrain changes, the staggered film pressing wheels 544 can cooperate with each other. On the one hand, the drip irrigation pipe can be guided more accurately to ensure that it always remains on the correct laying route. On the other hand, the staggered film pressing wheels 544 increase the contact points and support points between the equipment and the ground, thereby improving the stability of the equipment during operation and reducing the errors in film laying and pipe laying caused by equipment shaking.
