Description

Technical Field

[0001] This invention relates to the field of water conservancy construction equipment and agricultural machinery equipment, specifically to an agricultural combined multi-functional land grader. Background Technology

[0002] Agricultural graders are widely used in farmland improvement. With the continuous development of modern intensive agriculture and the continuous improvement of agricultural mechanization, the requirements for graders are also getting higher and higher. Current graders can adjust the height and posture of the scraper in real time through laser ranging or satellite positioning, so as to achieve a high-precision and high-quality flatness effect on the land.

[0003] Traditional agricultural leveling equipment typically only performs leveling operations and lacks the function of clearing vegetation, gravel, and other debris. This necessitates clearing the land before leveling, increasing operating time and labor costs. Traditional equipment often requires multiple switching between clearing and leveling operations, resulting in discontinuous operation and affecting overall work efficiency. Many traditional leveling equipment have poor adaptability to terrain and cannot effectively cope with the challenges of complex terrain or different soil conditions. They also often require a lot of manual operation and adjustments, making the process cumbersome. After a breakdown, the repair and maintenance of some traditional leveling equipment are relatively complicated, resulting in long downtime. They are generally large in size, making transportation and deployment inconvenient. Summary of the Invention

[0015] Working Principle: This land leveling device is designed for leveling farmland while simultaneously clearing vegetation and debris. During operation, the main frame of the device is towed onto a vehicle via a trailer hitch, enabling rapid deployment and reducing vehicle operating costs. The vehicle tows the main frame to the work area. At the start of the work, adaptive mechanisms on both sides of the cantilever beam are activated according to the terrain angle of the work area. These mechanisms operate synchronously on both sides of the cantilever beam. The hydraulic drive component of the adaptive mechanism, after opening along the support beam, pushes the cam connected to the output end. The cam, through prying, causes the cantilever arm of the adaptive mechanism to rotate along both sides of the cantilever beam. As the first arm rotates synchronously, it drives the fixed leveling mechanism and the first hydraulic drive component to rotate. The inner end of the first hydraulic drive component begins to slide along the internal track of the arc-shaped limiting channel installed on both sides of the cantilever beam, and at the same time, it restricts the vertical movement of the leveling mechanism after it rotates. The leveling mechanism also rotates with the first arm. The collection bucket and collection pool included in the leveling mechanism rotate synchronously with the first arm until the collection bucket and collection pool are in contact with the inclined work surface. At the same time, the second hydraulic drive component included in the leveling mechanism is activated, which generates hydraulic pulling force, pulling the extension arm to begin rotating along the top wall of the collection bucket. This causes the recycling and crushing mechanism installed between the extension arms to begin rotating and approaching the work surface. When it is 15 centimeters away from the work surface, the hydraulic drive component... As the second stretching stops and the second hydraulic drive unit activates, the output motor simultaneously starts, generating rotational torque. This torque is transmitted via the belt drive to the linkage shaft within the recycling and shredding mechanism. The linkage shaft then drives the polygonal rotating frame to rotate along the bearing seat on the extension arm. Simultaneously, the bidirectional transmission assembly within the recycling and shredding mechanism generates bidirectional rotational driving force. The first bevel gear, housed within the curved frame of the bidirectional transmission assembly, rotates with the linkage shaft. This rotation drives the meshing bevel gear to rotate, and the second bevel gear, meshing with the other end of the linkage bevel gear, also rotates. Because they are coaxial, the second bevel gear and the first bevel gear rotate simultaneously in opposite directions. The second bevel gear also drives... The drive spindle rotates inside the polygonal rotating frame. The drive spindle and the linkage sub-shafts drive the polygonal rotating frame and the evenly distributed linkage sub-shafts to rotate and agitate simultaneously in opposite directions. Side rods mounted on the sidewalls of the polygonal rotating frame drive hooks to move counter-clockwise along a circular path. Meanwhile, the linkage sub-shafts drive the outerly distributed cutting blades to rotate clockwise. As the hooks pull up and remove the vegetation, the counter-rotating cutting blades simultaneously shred the vegetation. Utilizing the counter-rotating centrifugal force generated by the coaxial rotation, the vegetation is simultaneously pulled up and shredded. The vehicle then begins to travel along the top of the work area, driving the main frame and the leveling mechanisms mounted on both sides of the main frame via adaptive mechanisms to move along the work area.Simultaneously, the four end-mounted transport and towing mechanisms on the main frame are activated and displaced. The transport wheels, responsible for contacting the road surface, are attached to the four ends of the main frame via axles included in the transport and towing mechanisms. Damping rods are installed between the axles and the main frame, causing the transport wheels to rotate along the axles when encountering bumpy surfaces. The damping rods then provide bump damping. The entire device begins clearing the area to be leveled. The segmenting components installed at the front of the open end of the leveling mechanism first contact vegetation and debris. The conical racks included in the segmenting components, through their conical structure, cooperate with the curved... The frame picks up vegetation and debris, which is then pushed into the collection bucket by hooks. Vegetation is pulled by hooks and guided into a polygonal rotating frame for chopping, falling into the collection bucket simultaneously. While the equipment is leveling the ground, the bidirectional drive motor of the crushing and recycling mechanism mounted on the main frame is activated. The generated rotational torque is guided to two sets of aggregation linkage components within the crushing and recycling mechanism. Each aggregation linkage component, positioned opposite each other on both sides, includes a central rotating shaft located inside the collection bucket. The torque generated by the bidirectional drive motor is guided to the guide shaft within the aggregation linkage component. The guide shaft then transmits torque through a universal joint that deforms due to the rotation of the leveling mechanism. The two joint rings of the universal joint, after deforming with the leveling mechanism, also rotate, transmitting torque to a central shaft located inside the collection bucket. This central shaft, centered on the conveying pipe connecting the collection bucket and the collection pool, has two unidirectional helical blades, one with opposite spiral directions, mounted on either side. The rotation of the central shaft drives the unidirectional helical blades to rotate, simultaneously creating a force within the collection bucket towards the conveying pipe. The converging thrust simultaneously pushes the collected gravel, debris, and chopped vegetation into the collection pool. Meanwhile, a rear roller sleeve located at the end of the collection pool moves with the pool, while a smoothing roller inside the sleeve presses against the farmland, leveling the area as it moves. The crushing and recycling mechanisms continue operating until the towing vehicle reaches the end point of the work, thus completing the leveling process. After the debris collected in the pool is cleared, the leveling mechanism is retracted via an adaptive mechanism.

[0016] This invention provides a combined multi-functional agricultural land grader. It has the following beneficial effects: 1. This invention features rapid deployment and cost reduction: The agricultural leveling device is designed to be quickly connected to a vehicle, eliminating cumbersome installation steps and saving time. Simultaneously, the use of a trailer hitch reduces vehicle operating costs, minimizing the need for manpower and equipment. The agricultural leveling device is relatively simple to operate, primarily driven by a hydraulic system and an electric motor. Operators only need to perform simple control and supervision, eliminating the need for complex technical operations and reducing operational difficulty and risk.

[0017] 2. This invention has an all-around cleaning effect: The adaptive mechanism and the cleaning and leveling mechanism inside the agricultural leveling device can clean the vegetation and gravel debris on the surface to be worked from all directions. The rotation and hydraulic drive of the adaptive mechanism enable the cantilever and the cleaning and leveling mechanism to cover the entire surface to be worked, ensuring thorough cleaning. The design of the hydraulic drive component and the bidirectional transmission assembly enables the agricultural leveling device to realize the automatic rotation and drive of multiple components, thereby realizing automated leveling operations, which reduces the need for manual operation and improves work efficiency.

[0018] 3. This invention has efficient and multifunctional cleaning and recycling effects: The collection bucket and collection pool inside the agricultural leveling device can efficiently collect gravel, debris, and vegetation on the land to be leveled. Through the reprocessing and recycling of the crushing and recycling mechanism, the utilization efficiency of resources is further improved and waste is reduced. In addition to cleaning up vegetation and gravel on the land to be leveled, the agricultural leveling device can also crush and recycle. This multifunctionality makes the agricultural leveling device suitable for different types of land leveling work, improving its flexibility and applicability. Attached Figure Description

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.

[0022] Please see the appendix Figure 1 - Appendix Figure 2This invention provides an agricultural combined multi-functional land leveler, comprising: a main frame 1 for installing and fixing the structure of the land leveling equipment; a suspension beam 2 and a support beam 3 located above the main frame 1 for fixing the main structure of the land leveling equipment to the main frame 1; a trailer boom 4 located on one side of the main frame 1 for providing towing for a traction vehicle; the suspension beam 2 is distributed at the top center of the main frame 1; the support beam 3 is fixedly connected to the top of the main frame 1; the trailer boom 4 is fixedly connected to the side wall of the main frame 1; four sets of adaptive mechanisms 5 are distributed in pairs on both sides of the suspension beam 2; transport and towing mechanisms 6 are distributed at the four ends of the main frame 1; and two land leveling mechanisms 7 are provided. The two sets of leveling and grading devices are arranged opposite each other on the main frame 1 via adaptive mechanism 5. The recycling and crushing mechanism 8 is set on the leveling and grading mechanism 7, and the crushing and recycling mechanism 9 is set on the main frame 1 and extends into the two sets of leveling and grading mechanisms 7. The cantilever beam 2 is provided with arc-shaped limiting channels 10 on both sides. This leveling device is designed to level farmland while clearing vegetation and debris. During operation, the main frame 1 of the device is towed onto the running vehicle via trailer bar 4, which enables it to be deployed quickly and reduce the actual application value of the vehicle. The running vehicle tows the main frame 1 to the driving area on top of the work area via trailer bar 4 at the beginning of the work.

[0023] Please see the appendix Figure 1 - Appendix Figure 4 The adaptive mechanism 5 is located on both sides of the main frame 1, used to make the leveling equipment form an inclined structure for the operation. The adaptive mechanism 5 includes a cantilever 51 and a hydraulic drive 52. A protruding rod 53 is fixedly connected to the side wall of the cantilever 51 near the direction of the cantilever beam 2. The telescopic end of the hydraulic drive 52 is rotatably connected to the outer end of the protruding rod 53. The end of the hydraulic drive 52 away from the protruding rod 53 is rotatably connected to the support beam 3. A cantilever 54 is fixedly connected to the bottom side wall of the cantilever 51. The end of the cantilever 54 facing the direction of the main frame 1 is slidably connected to the arc-shaped limiting track 10. The adaptive mechanism 5 on both sides of the cantilever beam 2 is set according to the terrain angle of the agricultural operation area. Mechanism 5 operates synchronously on both sides of the cantilever beam 2. After the hydraulic drive component 52 included in the adaptive mechanism 5 is opened along the support beam 3, it pushes the protruding rod 53 connected to the output end. The protruding rod 53 causes the cantilever 51 included in the adaptive mechanism 5 to start rotating along both sides of the cantilever beam 2 by prying. While the cantilever 51 on both sides rotates synchronously, it drives the ground leveling mechanism 7 and the hydraulic drive component 52 fixed thereon to rotate respectively. The inner end of the hydraulic drive component 52 begins to slide along the internal track of the arc-shaped limiting channel 10 installed on both sides of the cantilever beam 2, and at the same time plays the role of limiting the vertical movement of the ground leveling mechanism 7 after rotation. The ground leveling mechanism 7 also rotates with the cantilever 51.

[0024] Please see the appendix Figure 1 - Appendix Figure 4The transport and towing mechanism 6 is located at the four ends of the main frame 1 and is used for the overall displacement and transportation of the equipment. The transport and towing mechanism 6 includes axles 61 and damping rods 63. Axles 61 are rotatably connected to the side wall of the main frame 1. A transport wheel 62 is rotatably connected to the end of axles 61 away from the main frame 1. The telescopic end of the damping rod 63 is rotatably connected to the transport wheel 62. The end of the damping rod 63 away from the axle 61 is rotatably connected to the side wall of the main frame 1. The transport and towing mechanisms 6 installed at the four ends of the main frame 1 are simultaneously activated to move. The transport wheel 62, which is responsible for contacting the road surface, is installed at the four ends of the main frame 1 through the axles 61 included in the transport and towing mechanism 6. At the same time, the damping rods 63 are installed between the axles 61 and the main frame 1 so that when the transport wheel 62 encounters a bumpy road surface, it will rotate along the axles 61. The damping rods 63 then cooperate to play a role in bump damping. The whole device begins to clear the flat ground to be operated.

[0025] Please see the appendix Figure 1 - Appendix Figure 6The leveling mechanism 7 is located on both sides of the main frame 1, and works with the cantilever 51 to fix and install the leveling structure. The leveling mechanism 7 includes a collection bucket 71, a collection pool 72, and a dividing assembly. A conveying pipe 73 connects the collection bucket 71 and the collection pool 72. The two sides of the extension arm 74 are rotatably connected to the top of the side wall of the collection bucket 71. The bearing seat 75 is fixedly connected to the end of the extension arm 74 away from the collection bucket 71.

A hydraulic connection is established between the bottom wall of the extension arm 74 and the collecting bucket 71. The second pressure drive component 710, the bottom of the collection pool 72 away from the bottom of the side wall of the collection bucket 71, is fixedly connected to a rear roller sleeve 711. The bottom of the rear roller sleeve 711 is provided with an opening, and a smoothing roller 712 is embedded in the rear roller sleeve 711 and extends out of the rear roller sleeve 711 through the opening. The collection bucket 71 and the collection pool 72 included in the leveling mechanism 7 rotate synchronously with the cantilever 51 until the collection bucket 71 and the collection pool 72 are in contact with the inclined work surface. At the same time, the hydraulic drive component 710 included in the leveling mechanism 7 is activated, which generates hydraulic tension and pulls the extension arm 74 to start rotating along the top wall of the collection bucket 71. This causes the recycling and crushing mechanism 8 installed between the extension arms 74 to start rotating and approach the work area. When it is 15 centimeters away from the work area, the hydraulic drive component 710 stops stretching. At the same time, the rear roller sleeve 711 located at the tail end of the collection pool 72 moves with the collection pool 72, and the smoothing roller 712 installed inside the rear roller sleeve 711 is pressed against the farmland area.

[0026] Please see the appendix Figure 1 - Appendix Figure 10The recycling and shredding mechanism 8 is located inside the leveling mechanism 7. It works in conjunction with the extension arm 74, bearing seat 75, and belt drive 77 to remove vegetation from the area to be leveled. The recycling and shredding mechanism 8 includes a polygonal rotating frame 81 and a bidirectional rotating assembly. The recycling and shredding mechanism 8 is positioned between the extension arms 74. The side walls of the polygonal rotating frame 81 are fixedly connected to evenly distributed annular side rods 82. The side walls of the side rods 82 are provided with linearly equidistantly distributed hooks 83. Inside the polygonal rotating frame 81, two drive shafts 84 are rotatably connected to the two side walls facing the extension arms 74. A linkage secondary shaft 85 is rotatably connected between the drive shafts 84. The side walls of the linkage secondary shaft 85 are fixedly connected to equidistantly distributed rotating drums 86. The side walls of the rotating drums 86 are fixedly connected to evenly distributed annular cutting blades 87. The bidirectional rotation assembly is located on the outer wall of the polygonal rotating frame 81 and is coaxial with the linkage secondary shaft 85 and the drive main shaft 84. The linkage secondary shaft 85 passes through both side walls of the polygonal rotating frame 81 and is fixedly connected to the inner ring of the two side bearing seats 75. The bidirectional transmission assembly includes a mounting cylinder 88, a curved frame 89, a first bevel gear 810, a second bevel gear 811, and a linkage bevel gear 812. The drive main shaft 84 is rotatably connected to the side wall of the mounting cylinder 88 facing the polygonal rotating frame 81. The mounting cylinder 88 is fixedly connected to the side wall of the polygonal rotating frame 81. The curved frame 89 is fixedly connected to the inner side wall of the mounting cylinder 88. The first bevel gear 810 is rotatably connected to the inner side wall of the curved frame 89. The second bevel gear 811 is fixedly connected to the curved frame 89 relative to the first bevel gear. On the side wall of 810, a linkage bevel gear 812 is rotatably connected to the inner side wall of the curved frame 89. The linkage bevel gear 812 is perpendicular to bevel gear one 810 and bevel gear two 811, and is meshed with the key ends of bevel gear one 810 and bevel gear two 811. The drive main shaft 84 is fixedly connected to the shaft of bevel gear two 811, and the linkage secondary shaft 85 is fixedly connected to the shaft of the side wall of bevel gear one 810. The linkage secondary shaft 85 passes through the drive main shaft 84, the side wall of the mounting cylinder 88, and bevel gear two 811 in sequence and extends to bevel gear one 810. When the hydraulic drive component two 710 is opened, the output motor 76 is opened simultaneously to generate rotational torque, which is transmitted to the linkage secondary shaft 85 included in the recycling and crushing mechanism 8 through the belt drive component 77, so that the linkage... The secondary shaft 85 drives the polygonal rotating frame 81 to rotate along the bearing seat 75 on the extension arm 74. Simultaneously, as the secondary shaft 85 rotates, the bidirectional transmission assembly included in the recycling and crushing mechanism 8 begins to generate bidirectional rotational driving force. The bevel gear 810, installed inside the curved frame 89 included in the bidirectional transmission assembly, rotates along with the secondary shaft 85. The rotation of bevel gear 810 simultaneously drives the meshing bevel gear 812 to rotate, while the bevel gear 811, meshing on the other side of the meshing bevel gear 812, also rotates. Because it is coaxial with bevel gear 810, bevel gear 811 and bevel gear 810 rotate simultaneously in opposite directions. Bevel gear 811 also drives the drive shaft 84 to rotate inside the polygonal rotating frame 81.The main drive shaft 84 and the linkage secondary shaft 85 drive the polygonal rotating frame 81 and the evenly distributed linkage secondary shafts 85 to rotate and agitate in opposite directions simultaneously. The side rods 82 attached to the side wall of the polygonal rotating frame 81 drive the hooks 83 to move counterclockwise along a circumferential path, while the linkage secondary shafts 85 drive the outerly distributed cutting blades 87 to rotate clockwise. As the hooks 83 hook up and pull out the vegetation to be worked on, the counterclockwise rotating cutting blades 87 simultaneously shred the vegetation. The coaxial reverse rotation generates a counterclockwise rotation. Using centrifugal force, the equipment simultaneously lifts and shreds the vegetation and debris. The dividing component, installed on the front of the open end of the leveling mechanism 7, first contacts the vegetation and gravel. The conical rack 78 within the dividing component, through its conical structure, works in conjunction with the curved frame 89 to scoop up the vegetation and debris. The gravel is pushed into the collection bucket 71 by the hook 83, while the vegetation is hooked by the hook 83 and guided into the polygonal rotating frame 81 for shredding, simultaneously falling into the collection bucket 71. This process leveling the ground is performed simultaneously.

[0027] Please see the appendix Figure 1 - Appendix Figure 9The crushing and recycling mechanism 9 is located inside the leveling and clearing mechanism 7. It works in conjunction with the collecting bucket 71 and the conveying pipe 73 to remove large pieces of debris from the area to be leveled.

The aggregation linkage components extend into the collecting bucket 71. The aggregation linkage components include a guide shaft 92, a universal joint 93, a central rotating shaft 94, a first unidirectional spiral blade 95, and a second unidirectional spiral blade 96. 6. The guide shaft 92 is fixedly connected to the output ends of the bidirectional drive motor 91 on both sides. The universal joint 93 is rotatably connected to the end of the guide shaft 92 away from the bidirectional drive motor 91. The central rotating shaft 94 is rotatably connected to the end of the universal joint 93 away from the guide shaft 92. The first unidirectional spiral blade 95 is fixedly connected to the part of the central rotating shaft 94 extending to the collecting bucket 71. The second unidirectional spiral blade 96 is fixedly connected to the side wall of the central rotating shaft 94 extending to the collecting bucket 71 and away from the side wall of the first unidirectional spiral blade 95. The spiral directions of the first unidirectional spiral blade 95 and the second unidirectional spiral blade 96 are set to be opposite. The bidirectional drive motor 91 included in the crushing and recycling mechanism 9 mounted on the frame 1 generates rotational torque, which is then guided to two sets of aggregation linkage components included in the crushing and recycling mechanism 9. The aggregation linkage components arranged opposite each other on both sides include a central rotating shaft 94 located inside the collection bucket 71. The torque generated by the bidirectional drive motor 91 is guided to the guide shaft 92 included in the aggregation linkage component. The guide shaft 92 then transmits the torque through the universal joint 93, which deforms due to the rotation of the leveling mechanism 7. The two joint rings of the universal joint 93 can also rotate after deforming with the leveling mechanism 7. The transmission mechanism transfers torque to the central shaft 94 located inside the collection bucket 71. The central shaft 94 is centered on the conveying pipe 73 that connects the collection bucket 71 and the collection pool 72. On both sides, there are two unidirectional spiral blades 95 and 96 with opposite spiral directions. The rotation of the central shaft 94 will drive the unidirectional spiral blades 95 and 96 to rotate, and at the same time, a thrust will be generated inside the collection bucket 71 and converge toward the conveying pipe 73, pushing the collected gravel, debris and chopped vegetation into the collection pool 72 for collection.
