Saline-alkali land is widely distributed around the world, and with the increasing shortage of arable land resources, how to effectively use saline-alkali land for agricultural production has become an urgent problem to be solved. The high salt environment of saline-alkali land will interfere with the absorption of water and nutrients by crops, inhibit seed germination and root development, and lead to poor growth of crops, low yields, or even crop failure.

[0003] Ridge-forming and film-covering technology has been applied to a certain extent as an effective means to improve the planting conditions of saline-alkali land. Ridge-forming can improve the air permeability and drainage of the soil and reduce the accumulation of salt on the soil surface; film covering can keep warm, retain moisture, inhibit the rise of salt, and reduce the growth of weeds, creating a relatively suitable growth microenvironment for crops. However, the existing ridge-forming and film-covering devices are difficult to ensure the flatness and stability of the film materials during the film material transportation process, and are prone to wrinkles, deviations, and other problems, affecting the quality of the film covering; the adaptability to film materials of different thicknesses, materials, and widths is poor, and it cannot meet the diverse planting needs; under complex saline-alkali land terrain conditions, the mobility and operating accuracy of the device are difficult to guarantee, resulting in uneven effects of ridge-forming and film covering; in addition, the structural design of the device is often not compact enough, and it occupies a large space during transportation and non-operating states, and the durability and ease of maintenance of the components also need to be improved.

[0020] 4. The electric-controlled rotating table in the present invention can accurately control the rotation angle of the rotating shaft, and then adjust the position and posture of the movable frame and the first conveying roller and the second conveying roller installed thereon.

When performing ridging and film coating for saline-alkali farmland planting, the stretching frame 12 is first unfolded to one side by using the adjustment component, and then the film material is discharged by using the film discharge roller 16, and the film material is spread on the upper end surface of the ridge with the help of the film transport component. The film transport component can largely ensure the flatness of the film material during the film coating process, thereby improving the film coating quality.

[0035] The film coating unit includes a second connecting bracket 34, which is arranged on one side of the stretching frame 12, and a connecting frame 41 is fixedly arranged on the other side of the second connecting bracket 34, and a film coating assembly is arranged on one side of the connecting frame 41. The film coating assembly cooperates with the film transport assembly to coat and position the film material on the upper end surface of the ridge forming area to ensure the stability of the film coating.

[0036] In the above specific embodiment, the present invention connects the mounting frame 1 and the first connecting bracket 8 through a bolt group, and can be movably arranged to facilitate connection with the traction machinery, so that the device can stably move in the farmland with the help of the power of the traction machinery, adapt to different terrains and operation routes, and improve the mobility and operation range of the device. The reliable connection between the mounting frame 1 and the first connecting bracket 8 and the traction machinery ensures that during the ridging and film covering process, the device can move along a predetermined trajectory to ensure the accuracy and continuity of the operation; in addition, the soil turning component fixed on the fixed plate 17 can turn the soil before ridging and film covering, improve the soil structure, make the soil more loose, and be conducive to the growth of crop roots and the penetration of water and nutrients. The turned soil also provides better basic conditions for subsequent ridging operations, thereby improving the quality and efficiency of ridging;

[0037] The automatic unwinding function of the film material is realized by utilizing the rotation setting of the stretching frame 12 and the cooperation of the movable side plate 15 and the film unwinding roller 16 on the film unwinding frame 14. This design can automatically and evenly release the film material according to the progress of ridging and film unwinding without manual operation, which greatly improves the efficiency and speed of film unwinding and reduces the manpower cost and labor intensity. At the same time, the adjustable design of the movable side plate 15 can adapt to film rolls of different widths and facilitate the replacement of film rolls, thereby improving the versatility and flexibility of use of the device.

[0038] In addition, the film conveying component can ensure the flatness of the film material during the film covering process, avoid problems such as wrinkles, curling or uneven stretching of the film material, thereby ensuring that the film material can be tightly and evenly covered on the upper end surface of the ridge, improving the sealing and stability of the film covering, which is beneficial to the heat preservation and moisture retention of the soil and the inhibition of salt increase, creating good environmental conditions for the growth of crops, and the adjustment component facilitates the deployment operation of the extension frame 12, so that the device can quickly and accurately adjust the film placement position and angle in different operating scenarios, further improving the operating efficiency and film covering quality; finally, the second connecting bracket 34 and the connecting frame 41 provide a stable support and connection structure for the film covering component, so that the film covering component can work in conjunction with the film conveying component to accurately cover and position the film material on the upper end surface of the ridge area. This structural design ensures the firmness and stability of the film covering, prevents the film material from shifting or falling off under the influence of natural factors such as wind and rain, thereby ensuring the long-term effectiveness of the film covering, and improving the success rate of saline-alkali farmland planting and the yield of crops.

[0039] Specifically, the soil turning assembly includes a transmission frame 3, the transmission frame 3 is fixedly arranged inside the two fixed plates 17, and the driving frames 2 are fixedly arranged at both ends of the transmission frame 3, a driving motor 7 is fixedly arranged in the middle of one side of the transmission frame 3, and a driving rod 6 is rotatably arranged inside the transmission frame 3, wherein the output shaft of the driving motor 7 and the surface of the driving rod 6 are connected by two meshing bevel gears, a soil turning frame 4 is rotatably arranged below the opposite side of the two driving frames 2, and both ends of the soil turning frame 4 and both ends of the driving rod 6 extend into the interior of the driving frame 2, and pulleys 5 are fixedly arranged at both ends of the soil turning frame 4 and both ends of the driving rod 6, and the two pulleys 5 located inside the driving frame 2 are connected by belt transmission.

[0040] It should be noted that before ridge forming and film covering are carried out on the saline-alkali farmland, the driving rod 6 is controlled to rotate by the output shaft of the driving motor 7, and the transmission of the pulley 5 is coordinated to rotate the soil turning frame 4. The soil turning frame 4 is used to turn the soil before ridge forming and film covering, so as to improve the soil structure and make the soil looser, which is conducive to the growth of crop roots and the penetration of water and nutrients. The turned soil also provides better basic conditions for subsequent ridge forming operations, thereby improving the quality and efficiency of ridge forming.

[0041] Specifically, the adjustment component includes a rotating sleeve 9, a rotating sleeve 9 is rotatably provided on the other side of the first connecting bracket 8, and a rotating rocker 10 is fixedly provided on one end of the rotating sleeve 9, a connecting block 13 is fixedly provided on one side of the extension frame 12, and an adjusting screw 11 is rotatably provided on one side of the connecting block 13, and one end of the adjusting screw 11 is connected to the internal thread of the rotating sleeve 9, wherein the adjusting screw 11 is located inside the connecting block 13 and can only rotate vertically, while the rotating sleeve 9 is driven by the rotating rocker 10 to rotate horizontally, so when the rotating sleeve 9 is driven to rotate by the rotating rocker 10, the adjusting screw 11 can be adjusted to the desired position. One end of the joint screw 11 is limited by the connecting block 13 for lateral rotation, so that the end of the adjusting screw 11 connected to the rotating sleeve 9 can be displaced toward the inside of the rotating sleeve 9. By adjusting the length of one end of the adjusting screw 11 located inside the rotating sleeve 9, the distance between the stretching frame 12 and the first connecting bracket 8 is adjusted, so that the space occupied by the entire coating device when not working is greatly reduced, and at the same time, the expansion operation of the stretching frame 12 is facilitated, so that the device can quickly and accurately adjust the film placement position and angle in different operating scenarios, further improving the operating efficiency and coating quality.

[0042] Furthermore, an adjusting frame 21 is movably provided on one side of the connecting block 13 through a bolt group, and a rotating frame 22 is fixedly provided on the movable end of the adjusting frame 21, a tension control frame 23 is rotatably provided on one side of the rotating frame 22 through a built-in rotation controller, and a tensioning roller 24 is rotatably provided inside the tension control frame 23, wherein the adjusting frame 21 is composed of two adjusting arms that can be flexibly rotated, and the position of the tension control frame 23 is adjusted according to the conveying position of the film material, so that the surface of the tensioning roller 24 is in contact with the lower part of the conveying surface of the film material, and the conveying tension of the film material is adjusted by the tensioning roller 24, and the conveying deviation of the film material is adjusted, and according to the conveying deviation of the film material, the tension control frame 23 is controlled to deflect in different directions, thereby changing the angle between the tensioning roller 24 and the film material, which plays a role in tension adjustment and deviation correction during the conveying process of the film material.

[0043] Specifically, the film transport assembly includes a first conveying roller 29 and a second conveying roller 32. The front and rear sides of the stretching frame 12 are fixedly provided with an electric control rotating table 27, and the front and rear sides of the stretching frame 12 are rotatably provided with a rotating shaft 26. The output ends of the two electric control rotating tables 27 are respectively fixedly connected to one end of the two rotating shafts 26, and the opposite ends of the two rotating shafts 26 are fixedly provided with a movable frame 25. One side of the two movable frames 25 is fixedly provided with a first mounting bracket 28, and the first conveying roller 29 is rotatably provided between the opposite sides of the two first mounting brackets 28. The tops of the two movable frames 25 are also fixedly provided with a fixed The bracket 30 is provided with a second mounting bracket 31 fixedly arranged on the surface of the two fixed brackets 30 by a bolt group, a second conveying roller 32 is rotatably arranged between the opposite sides of the two second mounting brackets 31, a scraper plate 33 is slidably arranged between the two movable frames 25 and between the two second mounting brackets 31, and one side of the two scraper plates 33 is limited by a bolt group, and the scraping sides of the two scraper plates 33 are respectively in contact with the surfaces of the first conveying roller 29 and the second conveying roller 32 to clean the dirt on the surfaces of the first conveying roller 29 and the second conveying roller 32, thereby ensuring the conveying stability of the film material.

[0044] It should be noted that when the film material is being conveyed, the first conveying roller 29 and the second conveying roller 32 are controlled to rotate to the upper end surface of the ridge forming area, and the film material is stably conveyed during the coating process by passing the film material around the upper surface of the first conveying roller 29, the upper surface of the second conveying roller 32 and the lower surface of the second conveying roller 32.

[0045] Specifically, one end of the second connecting bracket 34 and one end of the fixed bracket 30 are fixedly connected by a bolt group, and the coating assembly includes a support frame 35, one side of the support frame 35 and the bottom of the connecting frame 41 are movably connected by a bolt group, two connecting springs 37 are installed on the top of the connecting frame 41, and one end of the two connecting springs 37 is installed with a movable connecting frame 36, a limiting protrusion is provided on the surface of the support frame 35, and one side of the movable connecting frame 36 is movably contacted with one side of the limiting protrusion, a buffer spring 40 and a film pressing roller 38 are also rotatably provided on one side of the support frame 35, and the other end of the buffer spring 40 is movably connected to one side of the film pressing roller 38, and a film material positioning gear 39 is also fixedly provided on the other side of the support frame 35 by a bolt group.

[0046] It should be noted that after the film material is spread flat on the upper end surface of the ridge by the film transport assembly, the front and rear film pressing rollers 38 are used to roll the front and rear sides of the film material on the ridge surface, and at the same time, the film positioning gears 39 arranged on one side of the two film pressing rollers 38 are used to press the front and rear sides of the film material into the front and rear sides of the ridge area of ​​the farmland, thereby greatly improving the connection stability of the film material after coating the ridge area.

[0047] In a specific embodiment, the electric-controlled rotating table 27 of the present invention can accurately control the rotation angle of the rotating shaft 26, thereby adjusting the position and posture of the movable frame 25 and the first conveying roller 29 and the second conveying roller 32 installed thereon. This adjustable design enables the device to adapt to film materials of different thicknesses, materials and widths. By reasonably adjusting the roller spacing and angle, the tension and fit of the film material during the conveying process are guaranteed, and the film material is prevented from running off or loosening, thereby achieving stable and accurate conveying of the film material and improving the uniformity and quality of the coating; the fixed bracket 30, the first mounting bracket 28 and the second mounting bracket 31 provide a stable support structure for the conveying rollers. It is ensured that it will not shake or move during high-speed rotation, and the design of the scraper plate 33 effectively solves the problem of soil adhesion on the surface of the conveying roller. In the saline-alkali land working environment, the soil is more viscous and easily adheres to the roller surface. The accumulation of soil will affect the friction between the film material and the roller surface, and then affect the conveying stability of the film material. The scraper plate 33 can scrape off the soil on the roller surface in time through close contact with the surface of the first conveying roller 29 and the second conveying roller 32, keep the roller surface clean, maintain a stable friction coefficient between the film material and the roller surface, ensure the smooth conveying of the film material, reduce the film material jamming, tearing and other faults caused by unclean roller surface, and improve the working efficiency and the stability of the coating quality;

[0048] In addition, the support frame 35 provides a solid basic framework for the entire film covering assembly to ensure the stable operation of each component. The movable connecting frame 36 connected by the connecting spring 37 enables the film pressing roller 38 to have a certain elastic buffering capacity. When rolling the film material, it can automatically adjust the pressure of the film pressing roller 38 according to the unevenness of the ridge surface to ensure that the film material is closely fitted to the ridge surface and avoid the situation where there is a gap between the film material and the soil, thereby improving the sealing of the film covering, effectively preventing water evaporation and salt intrusion, and creating a good soil environment for crop growth; the film material positioning gear 39 is in the film covering process The film material positioning gear 39 plays a key role in the process. When the film pressing roller 38 presses the film material onto the ridged surface, the film material positioning gear 39 can accurately press the front and rear sides of the film material into the front and rear soils of the ridged area of ​​the farmland, forming a firm fixing effect. This positioning method greatly improves the connection stability of the film material after filming in the ridged area. Even under adverse natural conditions such as wind and rain erosion, it can effectively prevent the film material from being lifted or shifted, ensuring the long-term effectiveness of the film covering, reducing the later maintenance cost, being conducive to the long-term stable growth of crops, and improving the success rate and economic benefits of saline-alkali land planting.

[0049] In summary, the ridge-forming and film-covering device proposed in the present invention effectively solves the key problems such as stability, sealing and adaptability in the film material transportation and film-covering process through the coordinated cooperation between various components, provides efficient and reliable technical support for the cultivation of crops in saline-alkali land, and helps to improve the agricultural production efficiency and ecological environment of saline-alkali land.

[0050] Specifically, this embodiment also discloses a working method of a saline-alkali farmland planting ridging and film covering device, comprising the following steps:

[0051] Step 1: Install and connect the mounting frame 1 and one side of the first connecting bracket 8 to one side of the traction machine through a bolt group, and use the traction machine to cooperate with the mounting frame 1 and the first connecting bracket 8 to drive the device as a whole to move;
