Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural tillage machinery, in particular to a wind-erosion soil anti-erosion tillage implement. BACKGROUND

[0002] The wind-erosion soil anti-erosion tillage implement generally refers to a tillage machine designed to reduce wind erosion of the surface soil in arid and semi-arid regions. The main purpose of this kind of implement is to reduce wind erosion by reducing the surface wind speed, increasing the roughness of the soil surface, reducing the change of the soil structure by wind, and increasing the water storage capacity of the soil.

[0003] In areas prone to wind erosion, soil structure stability is a key prerequisite for ensuring agricultural production. Traditional tillage implements (such as a share plow and a rotary tiller) use a "full-layer turning" operation mode, which completely turns and breaks the surface to deep soil during operation, resulting in complete destruction of the original soil aggregate structure, a decrease in large pores and an increase in small pores, and a decrease in soil aeration and water permeability. At the same time, the surface soil rich in organic matter is mixed with the deep soil poor in nutrients, breaking the balance of soil nutrient stratification, and the loosened soil particles after turning are easily eroded by wind, further exacerbating soil structure degradation. In the existing related technology, some schemes attempt to reduce the disturbance of tillage to the soil, such as a wind-erosion black land seeder with patent number CN221203237U, which uses a hook opener and a hole-making cone to achieve local furrowing and seeding, which can reduce the disturbance range of the soil during the seeding process, but only targets the seeding process and cannot achieve deep tillage and improvement of the soil, and the soil structure in the disturbed area is not protected, still posing a risk of local structure damage. SUMMARY

[0006] Further, the support frame is a rod-shaped structure.

[0007] Further, the soil stirring mechanism comprises a plurality of spiral stirring rods, which are arranged around the output shaft of the first motor in a circumferential direction and are connected with the output shaft of the first motor, the spiral stirring rod is provided with a spiral groove extending spirally along the axis of the spiral stirring rod.

[0008] Further, the soil layer cutting surface of the soil layer cutting plate is an arc surface structure, the soil layer cutting plate has a cutting plow head, and the cross-sectional area of the cutting plow head gradually decreases along the advancing direction of the frame.

[0009] Further, the support rod is provided with a soil block cutting cone located in the surface soil passage, and the cross-sectional area of the soil block cutting cone gradually decreases along the advancing direction of the frame.

[0010] Further, the lifting power source is an electric push rod.

[0011] Further, the frame is connected with a vibration pressing device, the vibration pressing device is arranged along the advancing direction of the frame and is sequentially and spacedly arranged with the plurality of soil loosening mechanisms installed on the support frame, and the vibration pressing device is used to press the surface soil flowing out of the surface soil passage.

[0012] Further, the frame is further connected with a film laying device, and the film laying device is arranged along the advancing direction of the frame and is sequentially and spacedly arranged with the vibration pressing device.

[0013] Further, the film laying device comprises a film laying roller, a film pressing roller and a film inserting device, the film laying roller is connected to the vehicle frame through a connecting frame, the film pressing roller is installed on the vehicle frame through a first linear driving device, the film inserting device is installed on the vehicle frame through a second linear driving device, and the film laying roller, the film pressing roller and the film inserting device are sequentially and spacedly arranged in the direction opposite to the traveling direction of the vehicle frame.

[0015] Compared with the prior art, the application has the following advantages: Based on the fact that the support frame extends horizontally along the first direction and the plurality of soil loosening mechanisms are sequentially and spacedly arranged along the length direction of the support frame, the extending direction of the support frame forms a natural angle with the traveling direction of the vehicle frame when the vehicle frame travels. This design enables the soil loosening mechanisms to work in an inclined posture relative to the traveling direction, and the working tracks of the adjacent soil loosening mechanisms are staggered and closely connected, forming a continuous staggered soil loosening belt. On the one hand, the staggered soil loosening belt can effectively penetrate the deep layer of soil, break the plough pan formed by long-term plowing, open the air and water channels in the soil, and significantly improve the soil permeability, thus creating a good environment for the growth of crop roots. On the other hand, part of the soil ridge that is not disturbed is reserved due to the staggered arrangement, which can serve as a natural windbreak to weaken the surface wind speed and reduce the erosion of the surface soil by wind, thus significantly reducing the risk of wind erosion. Meanwhile, compared with the traditional plowing mode, the inclined arrangement can accommodate more soil loosening mechanisms in a unit working width, thus greatly improving the plowing efficiency and avoiding the formation of continuous long wind erosion gullies in the plowing mode, which further reduces the risk of wind erosion from the design of the working track.

[0016] The first motor output shaft is movably arranged in the through hole of the support rod and is in transmission connection with the soil stirring mechanism, and the lifting cylinder of the surface soil protection mechanism is movably arranged on the periphery of the support rod, so that the driving function and the protection function are compactly integrated on the core component of the support rod. The integrated design not only makes the whole soil loosening mechanism more stable, greatly saves the space occupation, but also optimizes the power transmission path, the first motor directly drives the soil stirring mechanism, reduces the energy loss of the intermediate transmission link, realizes the efficiency and precision of power transmission, and ensures that the soil stirring mechanism can stably output the crushing and stirring power. At the same time, the lifting driving mechanism is arranged around the support rod through the lifting cylinder, so that the height of the soil protection plate can be flexibly adjusted. Whether it is the difference in surface soil thickness in different regions or the required tillage depth for different crop planting, it can be quickly adapted, and the environmental adaptability and actual operability of the machine are significantly enhanced. In addition, this integrated design also simplifies the complex transmission system and multi-bracket structure of the traditional tillage machine, reduces the mechanical failure points, and reduces the difficulty and cost of daily maintenance. During operation, the rotating soil stirring mechanism can efficiently break up the lower soil, improve the soil aggregate structure, and improve the soil fertility; and the soil protection plate synchronously inhibits the excessive disturbance of the surface soil during operation, ensuring the relative flatness and stability of the ground. The cooperative working mechanism of driving and protection not only realizes efficient soil loosening and soil crushing to improve the physical and chemical properties of the soil, but also effectively inhibits the wind erosion problem caused by tillage operation, truly realizes the dual benefits of wind erosion protection and soil improvement, and balances the agricultural production efficiency and ecological protection demand.

[0017] Based on the soil loosening mechanism comprising a support rod, a soil layer cutting plate, a soil stirring mechanism and a surface soil protection mechanism, and the soil protection plate and the soil layer cutting plate are arranged in layers to form a surface soil passage, a scientific layered operation mode of loosening below and protecting above is constructed. During operation, the soil layer cutting plate is first cut into the lower layer of soil under the action of the support rod, preliminarily cutting and loosening the deep layer of soil, laying a foundation for the subsequent operation of the soil stirring mechanism; and the soil protection plate located above can flexibly adjust the height through the lifting driving mechanism, ensuring that it always adapts to the surface soil thickness of different plots.

This layered mode not only fully loosens the deep layer of soil and improves the structure of the deep layer of soil, but also protects the original soil structure of the surface layer of soil to the greatest extent, and can also retain the cover of surface residues, fallen leaves and the like. The completeness of the surface structure and the retention of the cover can reduce the evaporation loss of soil moisture and reduce the probability of soil particles being lost due to wind action, fully meeting the requirements of modern conservation tillage for surface soil protection, and realizing the cooperation of tillage and soil protection.

[0023] Referring to Figures 1-8 A wind erosion soil anti-erosion tillage machine according to a preferred embodiment of the present application comprises a frame 1 and a plurality of soil loosening mechanisms 3; the frame 1 is connected with a support frame 2, the support frame 2 extends horizontally along a first direction; a plurality of the soil loosening mechanisms 3 are installed on the support frame 2 and are distributed along the length direction of the support frame 2; the soil loosening mechanism 3 comprises a support rod 31, a soil layer cutting plate 32, a first motor 34, a soil stirring mechanism 35 and a surface soil protection mechanism 36; the support rod 31 is connected with the soil layer cutting plate 32 and supports the soil layer cutting plate 32, the support rod 31 has a through hole 311 extending along the height direction of the support rod 31, the first motor 34 is installed on the support rod 31, the output shaft of the first motor 34 is movably arranged in the through hole 311 and penetrates through the soil layer cutting plate 32 and is connected with the soil stirring mechanism 35; the surface soil protection mechanism 36 comprises a lifting driving mechanism 361 and a soil protection plate 362, the lifting driving mechanism 361 comprises a lifting power source 3611 and a lifting cylinder 3612, the lifting power source 3611 is drivingly connected with the lifting cylinder 3612, the lifting cylinder 3612 is movably sleeved on the periphery of the support rod 31, the lifting cylinder 3612 is connected with the soil protection plate 362 and supports the soil protection plate 362, the soil protection plate 362 is arranged in layers with the soil layer cutting plate 32 to form a surface soil passage 37, the soil protection plate 362 has a soil protection surface 3621 located in the surface soil passage 37, and the soil protection surface 3621 is used to prevent the surface soil from rolling.

[0024] In the use of the erosion soil anti-erosion tillage machine, first start the machine, the frame 1 is driven by the matched power device, along the preset tillage direction smoothly. The support frame 2 directly connected with the frame 1, according to its own set first direction keep horizontal extension state, the extension direction provides stable load bearing foundation for the installation of subsequent multiple soil loosening mechanism 3, at the same time ensure that each soil loosening mechanism 3 can form reasonable distribution range in the working area. Because multiple soil loosening mechanism 3 along the length direction of support frame 2 interval distribution, the spacing between adjacent soil loosening mechanism 3 is accurately designed, so that the machine running process, each soil loosening mechanism 3 can form continuous and no missing uniform tillage coverage in the working area, avoid the appearance of tillage dead angle or repeated tillage area. Subsequently, the soil loosening mechanism 3 formally enters the working state, the support rod 31 in the soil loosening mechanism 3 one end is connected with the support frame 2 fixed, the other end is directly connected and stable support soil cutting plate 32, provides sufficient support force for soil cutting plate 32. In the process of machine continues to run, soil cutting plate 32 under the support of its own structure strength and support rod 31, smoothly cut into the soil inside, for the deep soil preliminary cutting and loosening work, break the deep soil hardening state, for the subsequent further soil loosening do a good job. At the same time, the first motor 34 installed on the support rod 31 is started synchronously, the output shaft of the first motor 34 according to the preset trajectory, activity through the through hole 311 along the height direction of the support rod 31 extending, and continuously through the soil cutting plate 32, and the soil stirring mechanism 35 located below the soil cutting plate 32 form stable transmission connection. Under the power of the first motor 34, the output shaft drives the soil stirring mechanism 35 high speed rotation, further crushing, stirring work for the deep soil preliminary loosening by soil cutting plate 32, the deep soil in the large block of soil particles scattered, optimize the soil particle size distribution, improve the aeration and permeability of deep soil. At the same time of deep soil loosening work, the surface soil protection mechanism 36 also play a role, avoid the surface soil in the process of tillage by excessive disturbance. The lifting drive mechanism 361 in the surface soil protection mechanism 36, its lifting cylinder 3612 activity set in the periphery of the support rod 31, can along the height direction of the support rod 31 flexible movement, lifting power source 3611 and lifting cylinder 3612 between the driving connection, can provide stable power for the movement of lifting cylinder 3612. The end of the lifting cylinder 3612 away from the lifting power source 3611 is directly connected and supported by the soil protection plate 362, by adjusting the output power and direction of the lifting power source 3611, the position of the lifting cylinder 3612 on the support rod 31 can be accurately changed, and the height of the soil protection plate 362 is adjusted, so that the soil protection plate 362 and the soil cutting plate 32 always keep the state of layered setting, and the surface soil passage 37 with a certain height and width is formed between them.The soil protection surface 3621 specially designed on the soil protection plate 362 is located inside the surface soil channel 37. During the whole process of the continuous movement of the machine and the deep soil loosening operation, the soil protection surface 3621 can directly contact with the surface soil to form a protective barrier, effectively prevent the surface soil from rolling, flying up or losing under the action of the tillage external force, and maximize the original structural integrity of the surface soil. Since the plurality of loosening mechanisms 3 are distributed at intervals along the support frame 2, and the support frame 2 extends in the first direction to form a reasonable angle with the machine movement direction, the trajectories of the loosening mechanisms 3 in the operation process are closely connected and matched with each other, which not only avoids the repeated overlap of the operation area, but also ensures the continuity of tillage. This structural design not only realizes the full loosening of the deep soil and improves the structure of the tillage layer of the soil, but also effectively protects the surface soil through the surface soil protection mechanism 36, maximizes the disturbance to the structure of the surface soil in the tillage process, reduces the loss and structural damage of the surface soil, thereby significantly enhances the anti-erosion ability of the wind-eroded soil itself, and achieves the core goal of anti-erosion tillage.

[0025] Obviously, based on the support frame 2 itself extending horizontally along the first direction, and the plurality of soil loosening mechanisms 3 are sequentially and spacedly distributed along the length direction of the support frame 2, when the vehicle frame 1 travels, the extension direction of the support frame 2 and the travel direction form a natural angle. This design makes the soil loosening mechanism 3 work in an inclined posture to the travel direction, and the working tracks of adjacent soil loosening mechanisms 3 are staggered and closely connected, forming a continuous staggered soil loosening belt. On the one hand, the staggered soil loosening belt can effectively penetrate the deep layer of soil, break the plough pan formed by long-term cultivation, open the internal ventilation and water permeation channels of the soil, and significantly improve the soil permeability, creating a good environment for crop root growth; on the other hand, under the staggered layout, part of the undisturbed soil ridge will be reserved, which can act as a natural windbreak to weaken the surface wind speed and reduce the erosion of surface soil by wind, significantly reducing the risk of wind erosion. At the same time, compared with the traditional straight-line cultivation mode, the inclined layout can accommodate more soil loosening mechanisms 3 in unit operation width, greatly improving the cultivation efficiency, and avoiding the continuous long strip erosion groove formed by straight-line cultivation, further reducing the risk of wind erosion from the design of the working track. Based on the first motor 34 output shaft movably penetrating the through hole 311 of the support rod 31 and being transmission connected with the soil stirring mechanism 35, and the lifting cylinder 3612 of the surface soil protection mechanism 36 movably sleeving the support rod 31, the driving function and the protection function are compactly integrated on the core component of the support rod 31. This integrated design not only makes the whole soil loosening mechanism 3 structure more stable, greatly saves the space occupation, but also optimizes the power transmission path, the first motor 34 directly drives the soil stirring mechanism 35, reduces the energy loss of the intermediate transmission link, realizes the efficiency and precision of power transmission, and ensures that the soil stirring mechanism 35 can stably output the crushing and stirring power. At the same time, the lifting driving mechanism 361 can flexibly adjust the height of the soil protection plate 362 by sleeving the support rod 31 through the lifting cylinder 3612, whether it is facing the difference of surface soil thickness in different regions, or the requirement of cultivation depth for different crop planting, it can be quickly adapted, significantly enhancing the environmental adaptability and practicality of the machine. In addition, this integrated design also simplifies the complex transmission system and multi-bracket structure of traditional cultivation tools, reduces the mechanical failure points, and reduces the difficulty and cost of daily maintenance. During operation, the rotating soil stirring mechanism 35 can efficiently break the lower soil, improve the soil aggregate structure, and improve the soil fertility; while the soil protection plate 362 synchronously inhibits the excessive disturbance of the surface soil by operation, ensuring the relative flatness and stability of the ground. This cooperative working mechanism of driving and protection not only realizes efficient soil loosening and soil crushing to improve soil physical and chemical properties, but also effectively inhibits the wind erosion problem caused by cultivation operation, truly realizes the dual benefits of wind erosion resistance and soil improvement, and meets the needs of agricultural production efficiency and ecological protection. Based on the soil loosening mechanism 3 comprising a support rod 31, a soil layer cutting plate 32, a soil stirring mechanism 35 and a surface soil protection mechanism 36, and the soil protection plate 362 and the soil layer cutting plate 32 are arranged in layers to form a surface soil passage 37, a scientific layered operation mode of loosening the lower layer and protecting the upper layer is constructed.During operation, the soil cutting plate 32 is first cut into the lower layer of soil under the action of the support rod 31, preliminarily cutting and loosening the deep soil, laying a foundation for the operation of the subsequent soil stirring mechanism 35; while the soil protection plate 362 located above can be flexibly adjusted in height through the lifting driving mechanism 361, ensuring that it always adapts to the thickness of the topsoil of different plots. The soil protection surface 3621 of the soil protection plate 362 is stably located in the topsoil passage 37, and can effectively block the surface soil during the high-speed rotation of the soil stirring mechanism 35 for crushing and stirring the deep soil, avoiding excessive rolling or being thrown out of the working area. This layered mode not only realizes the full loosening of the deep soil and improves the structure of the deep soil, but also maximizes the protection of the original soil structure of the surface soil, and can also retain the coverings such as stubble and fallen leaves on the ground. The integrity of the surface structure and the retention of the coverings can reduce the evaporation loss of soil moisture and the probability of surface soil particles being lost due to wind action, fully meeting the requirements of modern conservation tillage for surface soil protection, and realizing the cooperation of tillage and soil protection.

[0026] Preferably, in the present embodiment, the support frame 2 is a rod structure. The rod structure (such as a round pipe or a square pipe) itself has excellent bending and torsion resistance. It can provide a solid and stable foundation support for multiple soil loosening mechanisms 3, ensuring that the entire working width will not deform under uneven soil resistance, thereby ensuring that the tillage depth of each soil loosening unit is consistent. In addition to being a rod structure, the support frame 2 can also be a box beam structure or a truss structure.

[0027] Preferably, the soil stirring mechanism 35 comprises a plurality of helical stirring rods 351 which are circumferentially spaced apart around the output shaft of the first motor 34 and connected to the output shaft of the first motor 34, the helical stirring rods 351 being provided with helical grooves 352 extending helically along the axis of the helical stirring rods 351. The plurality of helical stirring rods 351 are circumferentially spaced apart along the output shaft to form an annular working range, and when rotating synchronously under the drive of the first motor 34, can form a full-range wrapping stirring to the deep soil which is preliminarily loosened by the soil cutting plate 32, so as to avoid the occurrence of dead angles which cannot be stirred. At the same time, the helical grooves 352 on the helical stirring rods 351 have a unique helical structure, and during rotation, the sidewalls of the helical grooves 352 will continuously cut, extrude and push the soil, on the one hand, the helical grooves 352 can gradually cut and refine the soil particles along the trajectory of the helical grooves 352, on the other hand, the helical grooves 352 can slowly push the deep soil upwards and outwards through the helical lift angle, and fully mix with the surrounding soil, break the structural barriers between soil layers, and significantly improve the stirring uniformity of the deep soil, so as to provide a more loose and breathable growth environment for the crop roots. The helical grooves 352 of the helical stirring rods 351 can not only break the soil, but also have a combing effect on the soil particles. The curved surface structure of the helical grooves 352 will gradually gather the fine soil particles along the helical trajectory, promote the formation of more stable aggregate structure of the micro soil particles, avoid the soil being excessively pulverized into fine sand which is easy to be blown away by the wind, and break the original large block structure to form an ideal soil state of broken but not scattered. This optimized soil aggregate structure can not only improve the water and fertilizer retention capacity of the soil, but also enhance the wind erosion resistance of the soil itself, reduce the risk of soil erosion by wind force due to the over-fine soil particles and loose structure after subsequent tillage, and further strengthen the anti-erosion core function of the machine.

[0028] Preferably, in the embodiment, the soil cutting surface of the soil cutting plate 32 is an arc surface structure, the soil cutting plate 32 has a cutting plow head 321, and the cross-sectional area of the cutting plow head 321 gradually decreases along the direction of travel of the vehicle frame 1. Designing the soil cutting plate 32 into an arc surface structure can realize sliding cutting. When it moves forward, the curved surface of the arc will guide the soil to be cut along the curve and slightly lifted upwards. This process is a continuous and smooth cutting process, similar to cutting something with an arc-shaped blade, which is more labor-saving and has a smoother cut than hacking straight up and down. This sliding cutting effect greatly reduces the lateral extrusion and operation vibration of the soil. It only cuts a narrow slit, without extending the crack to the surrounding, thereby maximizing the protection of the soil structure outside the tillage zone which is not cut. These undisturbed soil ridges are the natural barrier against wind erosion. The cross-sectional area of the tip of the plow head is the smallest. This wedge-shaped shape ensures that the soil is broken and loosened with the least resistance.

[0029] Preferably, in the present embodiment, the support rod 31 is provided with a soil cutting cone 312 located in the surface soil passage 37, the cross-sectional area of the soil cutting cone 312 gradually decreases along the direction of travel of the frame 1. During the travel of the frame 1, the surface soil passes through the surface soil passage 37, and the support rod 31 is located in the surface soil passage 37. If the surface soil is accumulated at the support rod 31, the soil cutting cone 312 will cut the surface soil into two halves and then flow out of the surface soil passage 37. This avoids the accumulation of soil in the surface soil passage 37 and ensures the stable operation of the system. The surface soil passage 37 is a relatively narrow space. If there is no cutting cone, larger soil blocks may temporarily accumulate in the passage, affecting the smooth passage of soil, and even causing unnecessary load on the soil stirring mechanism 35 or the soil protection plate 362.

[0030] Preferably, in the present embodiment, the lifting power source 3611 is an electric push rod. In addition to being an electric push rod, it can also be a gas rod or a hydraulic oil rod.

[0031] Preferably, in the present embodiment, the frame 1 is connected with a jolt compactor 4, which is arranged along the direction of travel of the frame 1 and is sequentially and spaced apart from the plurality of soil loosening mechanisms 3 installed on the support frame 2, and the jolt compactor 4 is used for jolt compaction of the surface soil flowing out of the surface soil passage 37. This arrangement can strengthen the stability of the surface soil and improve the wind erosion resistance. The surface soil flowing out of the surface soil passage 37, although prevented from rolling and losing by the soil protection plate 362, the surface layer structure may still be loose and easily blown by the wind, causing dust or loss. The jolt compactor 4 travels randomly and can timely perform jolt compaction on the surface soil flowing out of the surface soil passage 37. Through the combined action of vibration and pressure, the loose surface soil particles are tightly combined to form a more stable surface soil layer shell. This shell can directly resist the direct impact of wind on the surface soil, reducing the probability of the surface soil being blown up, further reducing the risk of wind erosion of the soil, and achieving secondary reinforcement of the anti-erosion effect compared to the protection method relying only on the soil protection plate 362. At the same time, it can simplify the operation process, improve the efficiency and integrity of the operation. In the prior art, if the surface soil after tillage needs to be compacted, additional special soil compaction equipment is often used for secondary operation, which not only increases the cost of machine investment, but also requires repeated trips to the field, which not only wastes time, but also may cause additional disturbance to the soil structure due to the secondary operation. The present arrangement integrates the jolt compactor 4 and the soil loosening mechanism 3 on the same frame 1 and sequentially completes the loosening, protection, and jolt compaction along the direction of travel, realizing an integrated tillage process of "loosening-soil protection-stabilization". Without additional operation steps and equipment, a single travel can complete multiple key operations, greatly reducing the number of field operations and time cost, while avoiding repeated interference to the soil by secondary operation, ensuring the integrity and stability of the soil structure after tillage, and balancing the operation efficiency and soil protection requirements. The jolt compactor 4 can be a vibrating road roller or a vibrating pressure forming machine.

[0032] Preferably, in the present embodiment, the vehicle frame 1 is also connected with a film laying device 5, which is arranged in sequence and at intervals along the traveling direction of the vehicle frame 1 with the vibration pressing device 4. Such arrangement can build double protection and maximize the reduction of wind erosion risk. Although the vibration pressing device 4 can make the surface soil form a stable shell, in extreme environments such as strong wind and heavy rain, the surface soil may still appear local peeling or washing. The film laying device 5 operates immediately after the vibration pressing device 4 and can tightly cover the surface of the surface soil after being stabilized by the vibration pressing device 4 with plastic film or ecological film to form a physical barrier. This barrier can directly isolate the contact between wind and surface soil, avoid the direct wind erosion of strong wind on the surface soil, and at the same time block the direct washing of rainwater on the surface soil, reduce the loss and hardening of surface soil caused by rainwater. In the prior art, the film laying operation usually needs to be carried out separately after soil loosening and compaction, which requires additional investment in film laying equipment and labor, and multiple operations are easy to cause the surface soil to be repeatedly rolled, which destroys the stable structure formed before. The present setting integrates the film laying device 5, the soil loosening mechanism 3 and the vibration pressing device 4 on the same vehicle frame 1, and completes the three key procedures in sequence along the traveling direction, which can realize the whole process operation from soil improvement to surface protection in one field round trip. Without additional equipment investment and manual follow-up paving, it not only reduces the operation time and equipment cost, but also avoids the disturbance of multiple operations on the soil, ensures the continuity and integrity of the tillage effect. At the same time, the integrated operation reduces the complexity of manual operation, especially suitable for mechanized tillage in large-scale wind erosion areas, which improves the practicality and popularization value of the technology.

[0033] Preferably, in the present embodiment, the film laying device 5 comprises a film laying roller 51 connected to the vehicle frame 1 through a connecting frame, a film pressing roller 52 installed on the vehicle frame 1 through the first linear driving device 6, and a film inserting device 53 installed on the vehicle frame 1 through the second linear driving device 7. The film laying roller 51, the film pressing roller 52, and the film inserting device 53 are sequentially and spacedly arranged in the direction opposite to the traveling direction of the vehicle frame 1. The sequential arrangement of the film laying roller 51, the film pressing roller 52, and the film inserting device 53 in the direction opposite to the traveling direction of the vehicle frame 1 forms a flow line operation mode for the entire film laying process. The film laying roller 51 first lays the film smoothly on the surface of the surface soil treated by vibration pressing, and then the film pressing roller 52 applies pressure to both sides of the film to preliminarily fix the film and remove air under the film. Finally, the film inserting device 53 inserts the edges of the film into the soil to complete the firm fixation. This continuous operation mode avoids the problems of film surface wrinkles, misalignment, or looseness that may occur in traditional segmented operation, ensures the close adhesion of the film to the ground surface, and significantly improves the film laying quality and operation efficiency. The film pressing roller 52 is installed on the vehicle frame 1 through the first linear driving device 6, and the film inserting device 53 is installed on the vehicle frame 1 through the second linear driving device 7, so that the heights of both can be adjusted in real time according to the ground surface undulation and soil hardness. On uneven wind-eroded land, this adjustable design can ensure uniform film pressing force and consistent film inserting depth, avoiding the problems of insufficient film pressing, excessively shallow or deep film inserting caused by terrain changes, and ensuring the stability of film laying in complex environments. Through the double fixation of film pressing and film inserting, the edges of the film are firmly fixed in the soil and can effectively resist strong winds. Compared with the traditional fixation method of relying on soil pressing or simple burying, this composite fixation method significantly improves the wind resistance of the film, prolongs the protection period, and further enhances the anti-erosion effect of wind-eroded soil. The first linear driving device 6 and the second linear driving device 7 can be electric push rods, air cylinders, or hydraulic cylinders. In addition to this combined film laying device 5, a rotary tillage film laying machine can also be used.

[0034] Preferably, in the embodiment, the support frame 2 is connected to the vehicle frame 1 through a mounting frame 8, the mounting frame 8 is provided with a second motor 81, the output shaft of the second motor 81 is drivingly connected with a driving gear 811, the support frame 2 has a rotating shaft 21, the rotating shaft 21 is connected with a driven gear 22, and the driving gear 811 and the driven gear 22 are gear matched. The second motor 81 drives the driving gear 811 to rotate, and drives the support frame 2 to rotate around the rotating shaft 21 through gear transmission, so as to adjust the included angle between the support frame 2 and the advancing direction of the vehicle frame 1. Such angle adjustment function enables the operator to flexibly change the operation track and coverage of the loosening mechanism 3 according to the soil type, the tillage depth requirement or the wind erosion degree. For example, the included angle can be reduced to increase the tillage track in the serious wind erosion area, and the included angle can be increased to improve the operation efficiency in the soil structure better area, which significantly improves the adaptability and operation flexibility of the machine. Compared with chain transmission or belt transmission, the meshing transmission mode of the driving gear 811 and the driven gear 22 has the advantages of high transmission efficiency, accurate transmission ratio and compact structure. During the tillage process, even if a larger soil resistance is encountered, the gear transmission can maintain stable power transmission and avoid accidental changes in the angle. Such stability is crucial for maintaining the uniformity of the operation depth and the track of the loosening mechanism 3, and is particularly suitable for operation in complex wind erosion soil conditions. The angle adjustment is realized through motor driving, and the operator does not need to manually adjust the position of the support frame 2, but can complete the adjustment in the cab through the control device. Such automatic adjustment mode not only improves the operation convenience, but also reduces the downtime adjustment time and improves the overall operation efficiency. At the same time, it avoids the safety hazards that may be caused by frequent off-car operations, and improves the operation safety. The design of the gear transmission type angle adjustment mechanism not only enhances the operation adaptability and operation convenience of the machine, but also improves the stability and reliability of the overall structure, and provides a more flexible and efficient solution for wind erosion soil erosion-resistant tillage.
