Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment for saline-alkali land improvement, specifically to a saline-alkali land improvement structure based on vertical rotary tillage and deep application of biochar. Background Technology

[0002] A saline-alkali land improvement structure based on vertical rotary tillage and stratified deep application of biochar typically consists of a vertical rotary tillage mechanism, a biochar stratified deep application mechanism, and a supporting control system. Its core lies in breaking up the saline-alkali soil layer through vertical rotary tillage and regulating soil water and salt distribution through stratified deep application of biochar, thereby improving soil physicochemical properties and increasing saline-alkali land productivity. Existing technologies suffer from the following drawbacks: Blockage easily occurs during biochar feeding, leading to discontinuous feeding. This can result in misaligned biochar application, failing to form an effective biochar barrier, or even operational interruption, making saline-alkali land improvement impossible. Furthermore, the vertical rotary tillage structure is difficult to disassemble and replace, and is prone to wear and tear during operation, requiring frequent disassembly, maintenance, or replacement. The inability to quickly disassemble and reassemble increases equipment maintenance costs. Therefore, this saline-alkali land improvement structure based on vertical rotary tillage and stratified deep application of biochar is proposed to address these problems. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with existing technologies, this invention provides a saline-alkali land improvement structure based on vertical rotary tillage and stratified deep application of biochar, which has the following beneficial effects:

[0018] 1. This saline-alkali land improvement structure based on vertical rotary tillage and stratified deep application of biochar utilizes an installation mechanism and a rotary tillage mechanism. A drive motor starts the mechanism, which in turn rotates the fixed pipe via a transmission wheel and belt. The rotation of the fixed pipe drives the installation plate and the rotary tillage mechanism to rotate, achieving vertical rotary tillage. When the rotary tillage mechanism needs to be installed or disassembled, pressing the U-shaped plate causes the pressure plate to push the wedge block and moving cylinder inward, compressing the fixing spring and simultaneously causing the locking block to disengage from the slot in the vertical plate, enabling quick disassembly of the rotary tillage mechanism. Conversely, quick installation is achieved by pressing the U-shaped plate. The connecting cylinder is installed on the outside of the fixed pipe, and a sealing ring ensures a tight connection to prevent biochar leakage. When the fixed pipe rotates, it drives the connecting cylinder and the discharge cylinder to rotate, while the spiral blades perform vertical rotary tillage on the soil. The bottom of the discharge cylinder has a constricted design, which facilitates the uniform application of biochar, achieving the goal of easy disassembly and replacement of the vertical rotary tillage structure.

[0019] 2. This saline-alkali land improvement structure based on vertical rotary tillage and deep layered application of biochar features an anti-clogging mechanism. When the motor starts, it drives the rotating shaft and transmission wheel to rotate. The connecting belt drives two rotating shafts to rotate synchronously. When the rotating shafts rotate, they drive the mixing blades to rotate inside the hopper, preventing biochar from clogging. At the same time, the rotating shaft drives the rotating rod to rotate through the driven wheel and the belt body. The rotating rod drives the rotating plate and the semi-circular rod to rotate. When the semi-circular rod rotates, it periodically hits the semi-circular block. With the cooperation of the return spring, the moving frame slides back and forth inside the vertical plate, causing the striking block to periodically hit the rear side of the hopper, further preventing biochar from clogging. This achieves the purpose of preventing biochar from clogging during feeding. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] Please see Figure 1-10This invention provides a technical solution: a saline-alkali land improvement structure based on vertical rotary tillage and deep application of biochar, including a mounting frame 1, a lifting component 2 extending to its bottom at the top of the mounting frame 1, a storage component 3 located behind the lifting component 2 at the top of the mounting frame 1, a connector 8 fixedly installed on the rear side of the mounting frame 1, and movable wheels 9 fixedly installed on both the left and right sides of the bottom of the mounting frame 1. An installation mechanism 4 extending to its bottom is provided inside the lifting component 2, a rotary tillage mechanism 5 extending to its bottom is provided inside the installation mechanism 4, an anti-clogging mechanism 6 extending to its inner side is provided at the bottom of the storage component 3, and a conveying mechanism 7 penetrating the mounting frame 1 and connected to the installation mechanism 4 is provided at the bottom of the storage component 3.

[0033] Mounting frame 1 serves as the main support frame for the entire improved structure, providing a mounting base and fixed position for other components. This ensures that all parts can be stably and orderly assembled, maintaining the stability and integrity of the overall structure and enabling the improved structure to operate normally. Connector 8 is used to connect other equipment or components. For example, the improved structure can be connected to tractor or other traction equipment, allowing the improved structure to move on saline-alkali land under the drive of the traction equipment, achieving large-area improvement operations. Moving wheels 9 support the weight of the entire improved structure and enable it to move flexibly on saline-alkali land, facilitating the movement of the improved structure to different working positions and improving the efficiency and flexibility of the improvement operations.

[0034] The lifting assembly 2 includes a limiting frame 21. The limiting frames 21 are fixedly installed at both the top left and right ends of the mounting frame 1. A lifting frame 22 extending to the bottom of the mounting frame 1 is slidably installed between the inner sides of the two limiting frames 21. An electric push rod 23 with its output end fixedly connected to the inner top wall of the lifting frame 22 is fixedly installed at the top of the mounting frame 1.

[0035] The limiting frame 21 restricts the sliding range of the lifting frame 22, ensuring that the lifting frame 22 can only move up and down in the vertical direction, preventing it from deviating or swaying during movement, and ensuring the accuracy and stability of the lifting action. The lifting frame 22 serves as the installation carrier of the installation mechanism 4. Through its own up and down movement, it drives the installation mechanism 4 and the rotary tillage mechanism 5 to lift as a whole, thereby realizing flexible adjustment of the rotary tillage depth and biochar application depth to adapt to the improvement needs of different saline-alkali lands. The electric push rod 23 provides lifting power. Through the extension and retraction movement of its output end, it pushes or pulls the lifting frame 22 to slide up and down within the limiting frame 21, realizing the automated control of the lifting component 2. It is easy to operate and can accurately control the lifting height.

[0036] The storage component 3 includes a support plate 31. Two support plates 31 are fixedly installed on the top of the mounting frame 1 and located behind the lifting frame 22. Two storage boxes 32 are fixedly installed between the two support plates 31. A feed pipe 33 extending to the top of the inner top wall of the storage box 32 is fixedly installed, and a discharge hopper 34 extending to the bottom of the storage box 32 is fixedly installed on the inner bottom wall of the storage box 32.

[0037] Valves are installed on the pipe wall of the feeding hopper 34. The two storage boxes 32 contain different types of biochar, and the appropriate biochar is selected at different depths. The support plate 31 is used to support and fix the storage box 32, and to securely install the storage box 32 on the top of the mounting frame 1, providing reliable support for the storage box 32 and ensuring that the storage box 32 will not shake or fall off during the movement and operation of the improved structure. As a storage container for biochar, the storage box 32 can hold a certain amount of biochar, providing sufficient biochar raw materials for saline-alkali land improvement and ensuring the continuity of improvement operations. The feed pipe 33 facilitates the addition of biochar to the storage box 32. Biochar can be smoothly poured into the storage box 32 from the outside through the feed pipe 33, which is simple to operate and improves the efficiency of adding biochar. The feeding hopper 34 plays the role of guiding the biochar to fall, and guides the biochar in the storage box 32 to the discharge pipe 71, so that the biochar can flow out of the storage box 32 in an orderly manner, avoiding the scattering or blockage of biochar during the fall.

[0038] The mounting mechanism 4 includes a fixed tube 401. The inner bottom wall of the lifting frame 22 is rotatably connected to the fixed tube 401 extending to its bottom. The fixed tube 401 is located on the front side of the storage box 32. A motor frame 402 is fixedly installed on the right side of the inner bottom wall of the lifting frame 22. A drive motor 403 is fixedly installed on the inner side of the motor frame 402. Transmission wheels 404 are fixedly installed at both the output shaft of the drive motor 403 and the outer side of the fixed tube 401. A belt 405 is connected between the outer sides of the two transmission wheels 404. A mounting plate 406 located below the lifting frame 22 is fixedly installed on the outer side of the fixed tube 401. Two rectangular holes 407 are opened on the inner side of the mounting plate 406, located on the front and rear sides of the fixed tube 401 respectively. A number of... Two wedge-shaped blocks 408 extending to the left and right sides of the mounting plate 406 respectively. On opposite sides of the front and rear wedge-shaped blocks 408, movable cylinders 409 that are slidably connected to the inner wall of the rectangular hole 407 are fixedly installed. The movable cylinders 409 on the left and right sides are symmetrically distributed. A fixing spring 410 is fixedly installed between the inner sides of the movable cylinders 409 on the left and right sides. A connecting plate 411 that fits against the outer side of the mounting plate 406 is fixedly installed between one side of the front and rear wedge-shaped blocks 408. Two locking blocks 412 that extend to the inner side of the mounting plate 406 are fixedly installed on one side of the connecting plate 411. A U-shaped plate 413 that extends to the outer side of the rectangular hole 407 is slidably installed on the inner side of the rectangular hole 407. A pressure plate 414 that is slidably connected to the two wedge-shaped blocks 408 is fixedly installed at one end of the U-shaped plate 413.

Both ends of the pressure plate 414 are inclined and adapted to the wedge block 408. The left and right sides of the mounting plate 406 have through holes adapted to the wedge block 408. The through holes are connected to the inner wall of the rectangular hole 407. A rubber pad is provided on the outer side of the U-shaped plate 413.

[0040] The fixed pipe 401 is rotatably connected to the lifting frame 22 and can rotate under the drive of the drive motor 403, thereby driving the mounting plate 406 and the rotary tillage mechanism 5 to rotate, realizing vertical rotary tillage. The motor frame 402 is used to fix the drive motor 403, providing a stable mounting position for the drive motor 403, ensuring that the drive motor 403 will not shake or shift during operation, and ensuring that the drive motor 403 can output power normally. The drive motor 403 provides rotational power, which drives the fixed pipe 401 to rotate through the transmission wheel 404 and belt 405, thereby driving the entire rotary tillage mechanism 5 to perform vertical rotary tillage. It is the power source for rotary tillage. The transmission wheel 404 and belt 405 constitute a transmission device, which transmits the power of the drive motor 403 to the fixed pipe 401, realizing the transmission and conversion of power, so that the fixed pipe 401 can rotate according to the speed of the drive motor 403. Rotation and mounting plate 406: Serving as the mounting platform for the rotary tillage mechanism 5, the rotary tillage mechanism 5 is securely mounted on the fixed pipe 401 through the engagement of the locking block 412 with the vertical plate 53. It also provides mounting space for components such as the wedge block 408 and the moving cylinder 409. The rectangular hole 407, wedge block 408, moving cylinder 409, fixing spring 410, connecting plate 411, and locking block 412 together constitute the locking device. By pressing the U-shaped plate 413, the pressure plate 414 pushes the wedge block 408 and moving cylinder 409 to move, compressing the fixing spring 410, thus achieving the engagement or disengagement of the locking block 412 with the vertical plate 53. This facilitates the installation and disassembly of the rotary tillage mechanism 5. The U-shaped plate 413 and pressure plate 414 serve as operating components. Pressing the U-shaped plate 413 moves the pressure plate 414, triggering the locking device and enabling quick installation and disassembly of the rotary tillage mechanism 5. The operation is simple.

[0041] The rotary tillage mechanism 5 includes a connecting cylinder 51, which is movably installed on the outside of the fixed pipe 401 and extends to its bottom. A sealing ring 52 that fits against the outside of the fixed pipe 401 is movably installed on the inside of the connecting cylinder 51. Vertical plates 53 are fixedly installed on both the left and right sides of the connecting cylinder 51. One end of the vertical plate 53 passes through and extends to the top of the mounting plate 401. A locking block 412 engages with the vertical plate 53. A discharge cylinder 54 that extends to its bottom is fixedly installed on the inside of the connecting cylinder 51. Spiral blades 55 are fixedly installed on the outside of the discharge cylinder 54.

[0042] The inner side of the connecting cylinder 51 is provided with an installation hole that matches the discharge cylinder 54. The upper and lower sides of the inner wall of the discharge cylinder 54 are open, and the bottom of the discharge cylinder 54 is narrowed. The inner bottom wall of the lifting frame 22 is provided with a round hole, and a bearing is fixedly installed inside the round hole. The fixing pipe 401 is rotatably connected to the lifting frame 22 through the bearing.

[0043] The connecting cylinder 51 connects the fixed pipe 401 and the discharge cylinder 54. It is connected to the fixed pipe 401 via a movable installation method and prevents biochar leakage via a sealing ring 52. Simultaneously, it provides an installation position for the vertical plate 53, allowing the rotary tillage mechanism 5 to be securely connected to the installation mechanism 4. The sealing ring 52 prevents biochar leakage at the connection between the connecting cylinder 51 and the fixed pipe 401, ensuring that the biochar can smoothly enter the discharge cylinder 54 and improve its utilization rate. The vertical plate 53 engages with the locking block 412, fixing the rotary tillage mechanism 5 to the installation plate 406. Furthermore, the design of the mounting slots facilitates... The rotary tillage mechanism 5 is easy to install and disassemble, ensuring its stability during rotation. The discharge cylinder 54 serves as the output channel for biochar, transporting biochar from the storage component 3 to the rotary tillage section. Its upper and lower openings and bottom constriction design facilitate the uniform flow and application of biochar, ensuring that biochar is accurately applied to the soil. During rotation, the spiral blades 55 perform vertical rotary tillage on the soil, breaking up the compacted soil layer, improving soil structure, increasing soil aeration and permeability, and fully mixing the biochar with the soil to enhance the improvement effect of biochar on saline-alkali land.

A transmission belt 607 is connected between the outer sides of the two driven wheels 607. A belt body 608 is connected to a rotating rod 606. A rotating plate 609 is fixedly installed on the outside of the rotating rod 606, located behind the vertical plate 601. Semicircular rods 610 are fixedly installed at both ends of the rear side of the rotating plate 609. Two movable frames 611 are slidably installed on the front side of the vertical plate 601 and extend to its rear side. A return spring 612 fixedly connected to the vertical plate 601 is fixedly installed on the front side of the inner wall of the movable frame 611. A connecting plate 613 is fixedly installed on the front side of the movable frame 611.

The semi-circular rod 610 is located above the semi-circular block 616. The number of stirring blades 617 can be set according to requirements and is distributed in a ring at equal distances.

[0046] The upright plate 601 provides mounting support for components such as the rotating rod 606 and the moving frame 611. Simultaneously, it limits the sliding range of the moving frame 611 through limiting holes, ensuring that the moving frame 611 can only move in a specific direction, guaranteeing the normal operation of the anti-clogging mechanism. The motor 602 provides power, driving the left rotating shaft 603 to rotate. This, in turn, drives the two rotating shafts 603 to rotate synchronously via the transmission wheel 604 and connecting belt 605, providing power support for the stirring blades 617 and subsequent anti-clogging actions. The rotating shaft 603 serves as the mounting shaft for the stirring blades 617 and the transmission wheel 604. Its rotation drives the stirring blades 617 to rotate within the hopper 34, preventing biochar from clogging within the hopper 34. Simultaneously, the transmission wheel 604... Power is transmitted via the drive wheel 604 and connecting belt 605. The drive wheel 604 and connecting belt 605 constitute a transmission device, transmitting the power of the motor 602 to the right rotating shaft 603, enabling the two rotating shafts 603 to rotate synchronously. This drives the stirring blades 617 to work simultaneously, improving the anti-clogging effect. The driven wheel 607 and belt body 608 further transmit the power from the rotating shaft 603 to the rotating rod 606, enabling the rotating rod 606 to rotate. This rotates the rotating plate 609 and the semi-circular rod 610, achieving a striking action and preventing blockage at the rear of the hopper 34. The rotating rod 606 is equipped with the rotating plate 609, and its rotation drives the rotating plate 609 and the semi-circular rod 610 to rotate, providing a power transmission path for the striking action. During the rotation of the rotating plate 609 and the semi-circular rod 610, the semi-circular rod 610 periodically strikes the semi-circular block 616, causing the moving frame 611 to move back and forth. This drives the striking block 614 to strike the rear side of the hopper 34, preventing biochar from accumulating and clogging the rear side of the hopper 34. The moving frame 611 slides within the limiting hole of the vertical plate 601, and its back-and-forth movement drives the connecting plate 613 and the striking block 614 to move, thus achieving the striking action. Simultaneously, the strip plate 615 and the semi-circular block 616 cooperate with the semi-circular rod 610 to complete the periodic striking action. The return spring 612 provides a restoring force to the moving frame 611, allowing it to quickly return to its initial position after the semi-circular rod 610 leaves the semi-circular block 616, ready for the next... The tapping action ensures continuity and stability. The connecting plate 613 and the tapping block 614 are driven by the moving frame 611. The tapping block 614 periodically taps the rear side of the feed hopper 34 to prevent biochar blockage. The connecting plate 613 connects the moving frame 611 and the tapping block 614. The strip plate 615 and the semi-circular block 616 cooperate with the semi-circular rod 610. When the semi-circular rod 610 rotates to the position of the semi-circular block 616, it hits the semi-circular block 616, causing the moving frame 611 to move backward, thus triggering the tapping action. The stirring blade 617 rotates in the feed hopper 34 to stir the biochar, preventing it from clumping or blocking in the feed hopper 34 and ensuring that the biochar can flow out of the feed hopper 34 smoothly.

[0047] The conveying mechanism 7 includes a discharge pipe 71. The discharge pipe 71 extending to the bottom of the inner bottom wall of the hopper 34 is fixedly installed. The inner top wall of the discharge cylinder 54 is rotatably connected to a connecting pipe 72 extending to the top of the mounting frame 1. A diversion pipe 73 is fixedly installed on the top of the connecting pipe 72. Both discharge pipes 71 are movably connected to the diversion pipe 73.

[0048] The discharge pipe 71 guides the biochar in the hopper 34 to the diversion pipe 73, which is a transition channel for the biochar from the storage component 3 to the conveying pipeline, ensuring that the biochar can enter the conveying system in an orderly manner. The connecting pipe 72 connects the discharge pipe 71 to the discharge cylinder 54, and the diversion pipe 73 collects the biochar from the two discharge pipes 71 and distributes it to the connecting pipe 72, finally conveying the biochar into the discharge cylinder 54, realizing the accurate delivery and application of biochar.

[0049] During use, move the modified structure to the saline-alkali land operation area, ensuring the moving wheels 9 are in stable contact with the ground. Connect the device to the drive mechanism via the connector 8. Check if the biochar content in the storage component 3 is sufficient; if insufficient, add biochar through the feed pipe 33. Adjust the height of the lifting component 2 according to the soil salinity and crop growth requirements to determine the rotary tillage depth and biochar application depth. Activate the electric push rod 23 to lower the lifting frame 22 to the set height, causing the rotary tillage mechanism 5 to contact the soil. Start the drive motor 403 to rotate the fixed pipe 401 and the rotary tillage mechanism 5, initiating vertical rotary tillage operations. Simultaneously, activate the anti-clogging mechanism. Motor 602 drives the mixing blades 617 to rotate, preventing biochar from clogging, and drives the striking block 614 to periodically strike the rear side of the hopper 34. Appropriate biochar is discharged as needed. Biochar enters the inner side of the discharge cylinder 54 from the storage component 3 through the conveying mechanism 7 and is evenly spread into the soil as the rotary tillage mechanism 5 rotates. After the operation is completed, drive motor 403 and motor 602 are turned off, the vertical rotary tillage and biochar spreading operation are stopped, and the electric push rod 23 is started to raise the lifting frame 22 to the initial height, which drives the rotary tillage mechanism 5 to leave the soil and move the improved structure to the next working area or storage location for necessary maintenance and upkeep.

[0050] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0051] In summary, this saline-alkali land improvement structure based on vertical rotary tillage and stratified deep application of biochar, through the installation mechanism 4 and the rotary tillage mechanism 5, drives the motor 403 to start, which in turn drives the fixed pipe 401 to rotate via the transmission wheel 404 and belt 405. The rotation of the fixed pipe 401 drives the installation plate 406 and the rotary tillage mechanism 5 to rotate, achieving vertical rotary tillage. When it is necessary to install or remove the rotary tillage mechanism 5, pressing the U-shaped plate 413 causes the pressure plate 414 to push the wedge block 408 and the moving cylinder 409 inward, compressing the fixing spring 410 and simultaneously activating the locking block 412. The rotary tillage mechanism 5 can be quickly disassembled by disengaging from the slot in the vertical plate 53, and vice versa for quick installation. The connecting cylinder 51 is installed on the outside of the fixed pipe 401, and the sealing ring 52 ensures a tight connection to prevent biochar leakage. When the fixed pipe 401 rotates, it drives the connecting cylinder 51 and the discharge cylinder 54 to rotate. At the same time, the spiral blades 55 perform vertical rotary tillage on the soil. The bottom of the discharge cylinder 54 is designed with a narrow opening, which is conducive to the uniform application of biochar. This achieves the purpose of easy disassembly and replacement of the vertical rotary tillage structure. By setting the anti-clogging mechanism 6, the motor 602 is started, driving the rotating shaft. Rotation of shaft 603 and transmission wheel 604 drives the two rotating shafts 603 to rotate synchronously via connecting belt 605. When rotating shaft 603 rotates, it drives the stirring blades 617 to rotate inside the feed hopper 34, preventing biochar blockage. Simultaneously, rotating shaft 603 drives rotating rod 606 to rotate via driven wheel 607 and belt body 608. Rotating rod 606 drives rotating plate 609 and semi-circular rod 610 to rotate. When semi-circular rod 610 rotates, it periodically strikes semi-circular block 616. With the cooperation of return spring 612, moving frame 611 slides back and forth inside vertical plate 601, driving a knocking action. The striking block 614 periodically taps the rear side of the feeding hopper 34 to further prevent biochar blockage, achieving the purpose of preventing blockage during biochar feeding. This solves the problem that blockage is very easy to occur during biochar feeding, leading to discontinuous biochar feeding. At best, it causes misalignment of biochar layering and failure to form an effective carbon barrier; at worst, it causes operation interruption, making saline-alkali land improvement operations impossible. In addition, the vertical rotary tillage structure is difficult to disassemble and replace. The vertical rotary tillage structure is prone to wear or breakage during operation, requiring frequent disassembly, inspection or replacement. It cannot be quickly disassembled and assembled, increasing the maintenance cost of the equipment.
