Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment, and more particularly to an agricultural soil covering machinery vehicle. Background Technology

[0002] Agricultural soil covering machinery is a special machine used in agricultural production to cover the soil after sowing. Its main function is to cover the seeds evenly, protect the seed germination environment, and at the same time play a role in conserving moisture and compacting the soil surface. However, the current mainstream soil covering or sealing machinery relies on a single operation mode such as rotary tiller rollers or shovels to scrape the soil. Its core contradiction is that it cannot take into account both the soil sorting accuracy and the stability of the ridge structure.

[0003] Taking the sandy loam soil region of northern China as an example, while traditional rotary tillage covering mechanisms can break the topsoil to a suitable particle size, they also mix stones and compacted soil clods into the covering layer, causing seeds to come into direct contact with coarse and hard particles. More seriously, the excessively crushed soil loses its coarse particle framework support, making the ridges prone to collapse during subsequent irrigation, especially in fields with steep slopes. The width of the ridge top is reduced more severely after a single irrigation, forcing farmers to repeatedly repair the ridges, increasing the average labor cost per acre. Summary of the Invention

[0004] The purpose of this invention is to provide an agricultural soil covering machine to solve the problem of poor ridge-forming stability of traditional soil covering machinery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an agricultural soil covering machinery vehicle, including multiple lifting assemblies installed at the rear of the vehicle and a soil taking component rotatably mounted thereon, as well as a soil covering component and a ridging component that work together, and a transmitter for transferring soil between the soil taking component and the soil covering component, and a transmission component symmetrically arranged on both sides of the soil taking component and driving the transmitter and the ridging component. The soil taking component includes a resistance wheel for cutting the soil and forming furrows when moving and a plow frame that works with the resistance wheel to transport the soil, and screen buckets for soil treatment are provided on both sides of the resistance wheel.

[0006] The soil covering assembly includes a dispersion bin connected to a screen hopper via a conveyor;

[0007] The ridging assembly includes a soil-conditioning assembly for trimming furrows and a buffer holding assembly for elastically applying pressure to the soil-conditioning assembly. The soil-conditioning assembly includes a drive rod and a soil-conditioning disc that rotates counterclockwise along the forward direction to form ridges.

[0008] As the soil-collecting component moves, it forms furrows and separates fine soil particles. The remaining stones and large soil particles are then piled on both sides of the raised beds by a counter-rotating soil-collecting disc to form a hard, sloping slope.

[0009] As a further description of the above technical solution: the lifting assembly includes a connecting frame and a movable frame movably connected thereto, and a pull frame for fixing the plow frame is installed on the upper surface of the movable frame, and a hydraulic rod is movably connected to the top of the pull frame and the connecting frame.

[0010] As a further description of the above technical solution: the resistance wheel includes two wheel frames connected to the movable frame, and the two wheel frames are rotatably mounted with a wheel disc. Several scrapers are fixed to the arc-shaped sidewall of the wheel disc, and the edge of the wheel disc is set in a blunt knife-edge shape.

[0011] As a further description of the above technical solution: the screen bucket includes a guide bucket that is slidably disposed on one side of the wheel, and the outer edge of the guide bucket is provided with a flared opening, and both the flared opening and the side of the guide bucket facing the wheel are provided with screens.

[0012] As a further description of the above technical solution: the transmitter includes a conveying pipe fixedly connected to the bottom of the feed hopper, and an auger slides through the inner wall of the conveying pipe, and the end of the conveying pipe is rotatably connected to the inner wall of the dispersion bin.

[0013] As a further description of the above technical solution: the transmission assembly includes a gear guard fixed to the movable frame, and a drive gear fixed to one end of the wheel is rotatably mounted on the inner wall of the gear guard. The drive gear meshes with a first output gear fixed to one end of the auger, and the first output gear meshes with a second output gear. A universal coupling is provided between the second output gear and the drive rod.

[0014] As a further description of the above technical solution: the soil-settling assembly also includes a bearing seat rotatably mounted on the surface of the drive rod, and a bent transmission plate is movably connected to the bearing seat.

[0015] As a further description of the above technical solution: the buffer holding assembly includes a threaded seat fixed on the movable frame, and a screw is threadedly engaged on the threaded seat. A slide is slidably disposed on the surface of the screw, and a spring is installed on one end of the slide and the screw together.

[0016] As a further description of the above technical solution: the soil covering component also includes a hanger fixed on the movable frame, and both ends of the hanger are movably connected to the two dispersion bins with threaded pull plates. The opposite ends of the two threaded pull plates on the same side are threadedly engaged with a threaded torsion piece, and an extension plate is slidably arranged on the dispersion bin.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] This solution, through its integrated mechanical design, simultaneously performs soil extraction, furrow formation, ridge formation, ridge side trimming, soil screening and covering, and sorting of hard soil clods and stones to create a highly hydrophobic, rain-resistant, and structurally reliable ridge structure in a single operation. This achieves efficient soil covering and erosion-resistant slope protection in synergy, significantly improving the ridge-making quality and operational efficiency of dryland agriculture. During mechanical movement, the blunt blades of the resistance wheels and scrapers cut into the soil, working in conjunction with the plow frame to lift the soil in an arc shape. Combined with screening by a two-way screen and crushing of small soil clods, the fine soil is transported by an auger to a dispersion bin for even covering, forming a germination protective layer with appropriate porosity, thus greatly improving seed germination rates.

[0019] Meanwhile, the counter-rotating soil-forming disc squeezes the sieved stones and hard soil clods to both sides of the furrow, forming a sloping interlocking slope, which improves drainage and allows the ridge to maintain its structural integrity under heavy rain. It is more stable than traditional furrows and greatly reduces maintenance costs. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figure 1 - Figure 12As shown, the present invention provides an agricultural soil covering machinery vehicle, including multiple lifting assemblies 10 installed at the rear of the vehicle and a soil-taking assembly 20 rotatably mounted thereon, as well as a soil covering assembly 50 and a ridging assembly 30 for cooperative operation, and a transmitter 40 for transferring soil between the soil-taking assembly 20 and the soil covering assembly 50, and a transmission assembly 60 symmetrically arranged on both sides of the soil-taking assembly 20 and driving the transmitter 40 and the ridging assembly 30. The soil-taking assembly 20 includes a resistance wheel 21 for cutting the soil and forming furrows during movement and a plow frame 23 for transporting soil in cooperation with the resistance wheel 21, and sieve buckets 22 for soil treatment are provided on both sides of the resistance wheel 21; by the cooperation of the blunt blade edge 213 of the resistance wheel 21 with the scraper 214, the soil is cut and initially crushed, while larger stones cannot be cut and can be directly stepped over without large stones affecting the use. Meanwhile, the double-layer screen 223 design of the sieve hopper 22 effectively separates fine soil from stones: the inclined surface of the screen 223 and the squeezing friction of the wheel 212 further break up larger soil clods, allowing the fine soil to be transported to the covering soil assembly 50 through the conveyor 40, while stones and hard soil clods are guided to the sides of the forward direction and fall off. This process not only achieves efficient soil screening but also reduces obstacles in subsequent ridging operations, ensuring the fineness and uniformity of the covering soil and improving sowing quality.

[0041] The soil covering assembly 50 includes a dispersing chamber 51 connected to the screen hopper 22 via a conveyor 40. The auger 42 in the conveyor 40 is linked to the drive gear 62, dynamically adjusting the soil delivery rate according to the vehicle's movement speed to ensure the soil coverage amount matches the travel speed. The dispersing chamber 51 evenly disperses the falling soil, achieving a smooth cover over the ridge surface and avoiding the uneven thickness common in traditional soil covering operations. This precise control improves soil utilization and provides a stable growing environment for seeds.

[0042] The ridging assembly 30 includes a soil-setting assembly 32 for shaping the furrows and a buffer holding assembly 31 for elastically applying pressure to the soil-setting assembly 32. The soil-setting assembly 32 includes a drive rod 321 and a soil-setting disc 322 that rotates counterclockwise along the forward direction to form a ridge. The counterclockwise rotating soil-setting disc 322 of the soil-setting assembly 32 can pile sieved stones and hard soil blocks on both sides of the furrows to form a sloping slope. This structure uses mechanical force to transform debris into reinforcing material, which not only avoids the impact of stone accumulation on the field, but also enhances the erosion resistance of the ridge through compaction, effectively preventing the ridge from collapsing due to rainwater or irrigation. At the same time, the elastic design of the buffer holding assembly 31 allows the soil-setting disc 322 to adapt to ground undulations, and reduces equipment wear by buffering with springs 314 when encountering obstacles.

[0043] When the soil-taking component 20 moves, it forms furrows and separates fine soil particles, which are then transferred to the soil-covering component 50 via the transmitter 40 for soil covering. Residual stones and large soil particles fall in the opposite direction and are piled on both sides of the furrows by the reverse-rotating soil-laying disc 322 to form a hard, sloping slope.

[0044] This solution is suitable for various working conditions, from sandy soil to stony soil. The design simultaneously reduces the cost of manual rock removal, minimizes production losses due to landslides, and allows the slope protection stones to naturally improve the soil's mineral composition after years of weathering.

[0045] Specifically, such as Figure 2 As shown, the lifting assembly 10 includes a connecting frame 11 and a movable frame 12 movably connected thereto. A pull frame 13 for fixing the plow frame 23 is installed on the upper surface of the movable frame 12, and a hydraulic rod 14 is movably connected to the top of the pull frame 13 and the connecting frame 11.

[0046] The connecting frame 11 is fixed to the main beam at the rear of the vehicle body. Its movable frame 12 is located on the connecting frame 11 and moves in conjunction with it. When the length of the hydraulic rod 14 changes, the movable frame 12 can be moved along the connecting frame 11 at different angles via the pull frame 13. When lifted, the resistance wheel 21 is suspended in the air; when pressed down, the resistance wheel 21 contacts and cuts the soil. The lifting assembly 10 driven by the hydraulic rod 14 can quickly adjust the working depth of the resistance wheel 21. By changing the angle between the pull frame 13 and the movable frame 12, the equipment can switch between "lifted and suspended" and "pressed down" states, adapting to the needs of different tillage stages and reducing empty-running losses. The transmission component 60 transmits power through gear meshing and a universal coupling 65, enabling synchronized operation of processes such as soil extraction, transport, and ridging.

[0047] Specifically, such as Figure 9 As shown, the resistance wheel 21 includes two wheel frames 211 connected to the movable frame 12, and the two wheel frames 211 are rotatably mounted with a wheel disk 212. Several scrapers 214 are fixed on the arc-shaped sidewall of the wheel disk 212, and the edge of the wheel disk 212 is set in the shape of a blunt knife edge 213.

[0048] By setting the wheel frame 211, the two ends of the wheel 212 can be supported. At the same time, the wheel frame 211 is fixed to the movable frame 12 to maintain the rotation support of the wheel 212. The edge of the wheel 212 is set with a blunt blade 213, which can cooperate with the scraper 214 to cut the soil.

[0049] Specifically, such as Figure 9 and Figure 11 As shown, the sieve hopper 22 includes a guide hopper 221 that is slidably disposed on one side of the wheel 212, and the outer edge of the guide hopper 221 is provided with a flared opening 222, and both the flared opening 222 and the guide hopper 221 are provided with a screen 223 on the side facing the wheel 212.

[0050] By setting up the guide hopper 221, the sieved soil can be gathered and transported into the conveying pipe 41. At the same time, the flared opening 222 at the top of the hopper has a large coverage area, ensuring that the soil is in full contact with it. Meanwhile, the filter screen is set on the side of the flared opening 222 and the guide hopper 221 facing the wheel 212. The direction of the flared opening 222 can maintain sieving when the soil is moved by gravity by the baffle plate. The screen 223 facing the wheel 212 is inclined. Larger soil particles entering here are gradually crushed by the squeezing and friction of the wheel 212 under the action of the inclined surface. After being crushed, they pass through the screen 223 and mix with the fine soil particles, while stones slide out during the rolling.

[0051] The flared design of the sieve bucket 222 and the inclined screen 223 not only increase the soil contact area, but also guide stones to slide out naturally through the inclined surface, reducing the risk of screen 223 clogging and extending the service life of the equipment.

[0052] Specifically, such as Figure 6 As shown, the transmitter 40 includes a conveying pipe 41 that is fixedly connected to the bottom of the guide hopper 221, and an auger 42 slides through the inner wall of the conveying pipe 41. The end of the conveying pipe 41 is rotatably connected to the inner wall of the dispersion bin 51.

[0053] By setting up a conveying pipe 41, the conveying pipe 41 can transfer the screened soil. The auger 42 inside can change with the moving speed and is driven by the first output gear 63, so the conveying speed changes accordingly, maintaining the uniformity of the soil covering.

[0054] Specifically, such as Figure 10 As shown, the transmission assembly 60 includes a gear guard fixed to the movable frame 12. The inner wall of the gear guard is rotatably mounted with a drive gear 62 fixed to one end of the wheel 212. The drive gear 62 meshes with a first output gear 63 fixed to one end of the auger 42. The first output gear 63 meshes with and drives a second output gear 64. A universal coupling 65 is provided between the second output gear 64 and the drive rod 321.

[0055] The gear guard of the transmission assembly 60 can support the drive gear 62, the first output gear 63 and the second output gear 64. When the drive gear 62 rotates with the first output gear 63, the first output gear 63 simultaneously meshes with the second output gear 64 and reverses the rotation direction relative to the drive gear 62, so that the soil-aligning disc 322 reverses along the forward direction.

[0056] Specifically, such as Figure 7 As shown, the soil leveling assembly 32 also includes a bearing 323 rotatably mounted on the surface of the drive rod 321, and a bent transmission plate 324 is movably connected to the bearing 323.

[0057] By setting the bearing seat 323, the drive rod 321 can be supported. The bearing seat 323 is subjected to the elastic downward pressure of the buffer holding assembly 31 through the transmission plate 324, which keeps the drive rod 321 pressed down. The drive rod 321 is based on the universal coupling 65 so that it can maintain power transmission when deflected. Both ends of the transmission plate 324 can move, and its top part can also be bent to meet the needs of force transmission at multiple angles.

[0058] The soil-forming plate 322 is a conical disc, and its installation position on the drive rod 321 can be adjusted as needed. Specifically, the installation method is to use screws in conjunction with the openings on the drive rod 321 to select different installation positions (not shown in the model diagram).

[0059] Meanwhile, the soil compaction plate 322 in this plan is removed from one side. Figure 1 In addition to the smooth surface shown, it also includes, for example, Figure 11 Of the four implementation methods shown, in some fields where furrows exist, the depth is insufficient, reducing the amount of soil extracted by the soil extraction component 20. For such fields, the following methods are used: Figure 11 As shown in sub-figure a, there are multiple holes on the surface, which can squeeze the dry soil on the side wall of the ridge through and collect it into the furrow when trimming one side of the ridge, and work with scraper 214 to replenish the soil volume.

[0060] At the same time, loam, clay and sandy soils were selected in that order. Figure 11 Sub-figures d, c, and b show the soil preparation pan 322. Sub-figure d is better suited for shaping relatively loose sandy soil, sub-figure c is better suited for leveling clay, and sub-figure b has a more balanced design for loam. In contrast, Figure 1 The smooth surface shown is suitable for fields containing stones and the aforementioned soils.

[0061] Specifically, such as Figure 7 As shown, the buffer holding assembly 31 includes a threaded seat 311 fixed on the movable frame 12, and a screw 312 is threadedly engaged on the threaded seat 311. A slide block 313 is slidably disposed on the surface of the screw 312, and a spring 314 is installed on one end of the slide block 313 and the screw 312.

[0062] By setting the buffer holding component 31, an elastic force can be applied to the transmission plate 324 to maintain an elastic downward pressure on the soil leveling disc 322. When the soil leveling disc 322 encounters a large stone block during movement, it can slide along the slide block 313 and compress the spring 314 to provide elastic downward pressure for the soil leveling disc 322. This ensures the leveling force of the furrows and also allows the slide block 313 to slide and the spring 314 to retract when encountering large obstacles, thus avoiding damage to components caused by rigid collisions.

[0063] At the same time, when needed, the screw 312 is rotated, causing its threaded engagement on the threaded seat 311 to shift, thereby increasing the pressure applied to the soil-forming disc 322, and the angle of the soil-forming disc 322 also changes accordingly.

[0064] Specifically, such as Figure 2 As shown, the soil covering component 50 also includes a hanger 53 fixed on the movable frame 12, and both ends of the hanger 53 are movably connected to the two dispersion bins 51 with threaded pull plates 55. The two threaded pull plates 55 on the same side are threadedly engaged with a threaded torsion piece 54 at opposite ends. An extension plate 52 is slidably provided on the dispersion bin 51.

[0065] By setting up the hanger 53, the hanger 53 can support the dispersion bin 51. The support is installed and suspended on the hanger 53 by two threaded pull plates 55 and a threaded torsion piece 54. By rotating the threaded torsion piece 54, the threaded torsion piece 54 is threaded and engaged with the opposite end of the two threaded pull plates 55, so that its overall length changes under the action of the threads, thereby controlling the tilt angle of the dispersion bin 51. At the same time, the extension plate 52 on it can adjust the length of the extension plate 52 while adjusting the tilt angle, so as to achieve accurate positioning of the soil covering position.

[0066] In use, this solution involves mounting multiple units of this equipment side-by-side at the rear of the vehicle via connecting brackets 11. This allows for multi-row operations to be completed in a single trip, significantly improving the efficiency of large-scale farming. The independent lifting assemblies 10 for each unit allow for individual adjustment of the working depth based on the terrain's undulations, ensuring consistency across multiple rows. Furthermore, the modular design facilitates disassembly and maintenance, enabling rapid adaptation to the farming needs of different fields. It is particularly suitable for mechanized operations in large-scale farmland, and the equipment moves along with the vehicle when mounted side-by-side.

[0067] When in use, the length of the hydraulic rod 14 changes, causing it to lift the pull frame 13 based on the connecting frame 11. Then, the pull frame 13, under the force, causes the movable frame 12 to deflect onto the connecting frame 11. The movable frame 12, through the wheel frame 211 of the resistance wheel 21, causes the wheel disc 212 to press down, so that the scraper 214 on the outer edge of the wheel disc 212, in conjunction with the wheel disc 212, inserts into the soil and cuts the soil.

[0068] Simultaneously, under downward pressure, the plow frame 23 inserts into the soil, and as the scraper 214 and the wheel 212 cut the soil, the scraper 214 pushes the cut soil into the plow frame 23, and, in conjunction with the plow frame 23, lifts the soil in an arc-shaped trajectory. At this time, furrows are dug in the ground. At the same time, as the tilt angle of the scraper 214 increases, the soil pushed by the plow frame 23 slides onto the screen 223. As the wheel 212 rotates, the soil is pushed onto the screen 223, and some soil enters the wheel 212. Between 2 and 223, as the disc 212 moves, the smaller soil clods are squeezed and crushed by the rubbing force and pass through the disc 223. The upper arc surface of the disc 223 filters the soil as it moves, while the side wall can crush the smaller soil clods, separating the soil into stones and hard soil clods. The larger stones are directly passed over by the disc 212, which realizes the soil collection and screening. At the same time, the separated hard soil clods and stones are pushed down to the sides in the direction of movement.

[0069] As the sieved soil enters the sieve 22, it converges into the conveying pipe 41. When the wheel 212 rotates, it drives two drive gears 62 to rotate at both ends. The drive gears 62 mesh with the first output gear 63 to drive the auger 42 to rotate. The auger 42 dynamically synchronizes the converged raw materials according to the change in moving speed, and transports the sieved soil to the dispersion bin 51, where it is evenly dispersed and slides down to cover the ridge with soil.

[0070] While the soil is being covered, as the movement continues, the drive gear 62 drives the second output gear 64 to reverse through the first output gear 63. At this time, the second output gear 64 drives the drive rod 321 to rotate through the universal coupling 65. As the drive rod 321 rotates, it drives the soil-forming disc 322 to rotate in the opposite direction of the forward movement. When the soil-forming disc 322 rotates, it squeezes the screened hard soil clods and stones to both sides of the ridge under the action of its arc-shaped surface, forming a drainage and reinforcement structure on both sides of the furrow after soil extraction. At the same time, the ridge is covered with fine soil, resulting in high overall ridge quality and effectively preventing the ridge from collapsing due to rainwater or irrigation after ridge formation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
