Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, specifically to a water-saving planting device and method for licorice and associated weeds growing together. Background Technology

[0002] Water-saving cultivation of licorice with associated weeds is a licorice cultivation model that combines ecological planting concepts with water-saving technologies. The core is to select and retain specific associated weeds in the licorice planting field, such as some drought-tolerant, shallow-rooted herbaceous plants, to construct a symbiotic system. This system inhibits the growth of noxious weeds to a certain extent, while simultaneously improving soil structure through the complementary effects of their root systems. However, existing planting techniques are only designed for single crops and cannot adapt to the needs of heterogeneous symbiosis, specifically manifested in the following ways: On the one hand, different companion weeds have different growth spaces and spreading characteristics. For example, when coexisting with low-growing, creeping weeds, a wider ground cover spacing is required, while when coexisting with upright, clump-forming weeds, a more precise row spacing is required to avoid excessive shading of the above-ground parts. Existing standardized planting models such as fixed ridge planting and equal row spacing hole planting use uniform plant and row spacing parameters, which cannot be customized according to specific weed species pairings. This results in the inability to achieve optimal allocation of light, heat, and space resources among species, often exacerbating unnecessary competition and weakening the mutually beneficial effect. On the other hand, licorice needs to be kept moist when it is planted. Traditional irrigation systems treat licorice and associated weeds as the same water-requiring object and irrigate them evenly. However, in reality, the water requirements and root distribution depths of the two are different. Even irrigation may lead to excess water in the shallow root area and insufficient water in the deep root area, or vice versa. It is impossible to achieve precise spatial allocation of water, which wastes water resources and may inhibit the growth of one side, thus disrupting the symbiotic balance. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a water-saving planting device and method for licorice and associated weeds that is simple in structure, rationally designed, and easy to use. By setting up a driving component to flexibly adjust the furrow spacing, it adapts to the planting density of licorice and the growth needs of associated weeds, improving the targeted nature of the operation. Furthermore, the furrow depth can be rationally adjusted according to planting conditions to ensure licorice growth and improve survival rate and yield. The addition of a multi-nozzle independent control valve design enables precise water supply, saves water resources, and adapts to diverse irrigation needs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a base with casters, a water tank disposed above the base, and rectangularly arranged support legs at the bottom of the water tank, the support legs being fixed to the base, and a drain pipe of the water tank passing through the base; it also includes: An extension pipe is installed at the bottom of the base by a pipe clamp, and the bottom end of the drain pipe is inserted and fixed inside the extension pipe. Several nozzles with control valves are connected to the bottom of the extension pipe. The fixing block is fixed in the frame groove opened in the base, and the front and rear sides of the fixing block are respectively connected to the movable brackets through the first drive component; the movable brackets have an inverted "L" shaped structure, and the vertical end of the movable bracket slides through the frame groove. There are two moving blocks, one of which is fixedly installed on the inner wall of the vertical end of the moving bracket; the outer side of the first moving block is connected to the second moving block through the second driving assembly. The trencher, comprising several trenchers, is respectively disposed on the underside of the fixed block, the first moving block, and the second moving block via connecting components; Through the above technical solution design, during trenching, the width between the first moving block and the fixed block is adjusted by the first drive component, and the width between the second moving block and the first moving block is adjusted by the second drive component, thereby adjusting the distance between the two adjacent trenchers to meet the growth and spread needs of associated weeds. In addition, the trencher is adjusted by the connecting component to change the trenching depth to meet the planting needs of licorice. After trenching, the water output of the spray head is controlled by starting and stopping the control valve on the spray head to spray water on the trench to keep it moist. At the same time, if the associated weeds also need water, the control valve on the upper side of the associated weeds is opened; otherwise, it is closed.

[0005] As a further improvement of the present invention, the first drive component includes: The guide seat consists of two guide seats, which are fixedly mounted on the outer wall of the fixed block, respectively, with movable blocks slidingly passing through each guide seat. The outer side of each movable block is connected and fixed to the vertical end of the movable bracket. A connecting rod, which is fixed between the left and right movable blocks; The first drive motor is fixedly mounted on the base by a motor bracket and is positioned between the fixed block and the movable bracket. The output end of the first drive motor is provided with a drive shaft, and a rotating component is sleeved and fixed on the drive shaft. The rotating component is movably sleeved on the connecting rod through the movable groove at its lower end. By designing the above technical solution, starting the No. 1 drive motor causes the rotating component to rotate, which in turn drives the connecting rod and the moving support.

[0006] As a further improvement of the present invention, support blocks are fixedly provided on both the left and right sides of the horizontal end of the movable bracket, and the support blocks are slidably disposed on the slide rail on the upper side of the base through the slide groove. The above technical solution design provides guidance for the movement, reinforcement, and directional reinforcement of the mobile support.

[0007] As a further improvement of the present invention, the second drive component includes: The fixing frame is an "L" shaped structure, and the vertical end of the fixing frame is fixed to the outer wall of the first moving block; a protrusion is fixedly provided on the upper outer side of the horizontal end of the fixing frame. The push block is movably inserted into the protrusion, and a connecting platform is fixedly provided on the outer side of the push block, which is connected to the second moving block. An electric push rod is fixedly mounted on the inner top surface of the horizontal end of the movable bracket, and a drive block is fixedly connected to the pushing end of the electric push rod, with a drive sleeve slidably sleeved on the drive block. The first connector is hinged to the right side of the drive sleeve via a hinge shaft, and the other end of the first connector is hinged to the right side wall of the fixed block via a hinge shaft. The second connector is hinged to the left side of the drive sleeve via a hinge shaft, and the other side of the second connector is hinged to the left side wall of the push block located between the connecting platform and the protrusion via a hinge shaft. Through the above technical solution design, the electric push rod is activated to drive the drive block. When the drive block moves, the drive sleeve moves through the hinged engagement of the first connecting piece. The movement of the drive sleeve, in turn, drives the push block through the hinged engagement of the second connecting piece, causing the connecting platform to move the second moving block and adjust the distance between the second moving block and the first moving block.

[0008] As a further improvement of the present invention, the connection component includes: A connecting block is fixedly connected to the lower side of a fixed block, and a connecting motor is fixed on one outer wall of the connecting block. The output end of the connecting motor passes through the connecting block and is provided with a rotating gear. A connecting frame is provided on the lower side of the rotating gear, and the connecting frame is hinged to the connecting block through a hinge shaft. The lower side of the connecting frame is connected to the trencher. An arc-shaped rack is fixed to the inclined end of the connecting frame, and the arc-shaped rack is meshed with a rotating gear. By starting the connecting motor, the rotating gear can be rotated to mesh with the arc-shaped rack, causing the connecting frame to rotate around its rotation center with the connecting block, thereby adjusting the trenching angle of the trencher and changing the trenching depth.

[0009] As a further improvement of the present invention, a U-shaped movable handle is provided on the upper side of the base, and a support rod is fixedly attached to the left end of the horizontal bar of the movable handle. The support rod is slidably engaged with the sliding groove on the outer side of the base through a sliding table. A drive platform is fixed on the inner wall of the support rod. The drive platform is in contact with the base. A hydraulic push rod is fixed on the left side of the drive platform and connected to the drive platform. With the above technical solution design, the hydraulic push rod can be activated to drive the drive platform and move the movable handle. When the drive platform moves to the right, the movable handle is exposed, making it easy to manually push the device. When the drive platform moves to the left, the movable handle is retracted.

[0010] As a further improvement of the present invention, a connecting buckle is provided on the right side of the base for connection with an external agricultural vehicle.

[0011] As a further improvement of the present invention, connecting strips are provided at the bottom of both the front and rear sides of the base, and the upper side of the connecting strips is connected to the base through the left and right protrusions; the movable wheels are respectively connected and installed on the outer side of the connecting strips.

[0012] The working principle of this invention is as follows: The device is connected to an external agricultural vehicle via a connecting buckle on the right side of the base. If manual movement is required, the hydraulic push rod is activated to drive the drive platform to the right, causing the "U"-shaped movable handle to protrude, making it easy for the operator to push. When manual movement is not required, the hydraulic push rod is activated to drive the drive platform to the left, retracting the movable handle to avoid interference during operation. Sufficient clean water is injected into the water tank, and it is checked whether the control valves of each nozzle are in the closed state. Start the first drive motor in the first drive assembly. The motor output drives the drive shaft and the fixed rotating component to rotate. Since the rotating component is movably mounted on the connecting rod through the lower movable slot, and the connecting rod is fixed between the left and right movable blocks, and the movable blocks slide through the guide seat on the outer wall of the fixed block, the rotation of the rotating component will generate a horizontal driving force on the connecting rod, causing the movable blocks to slide along the guide seat, and then driving the inverted "L"-shaped moving bracket fixed to the movable blocks to move horizontally along the frame groove of the base. During the movement of the moving bracket, the support blocks on the left and right sides of its horizontal end slide along the slide rail on the upper side of the base to achieve stable guidance and reinforcement of the moving bracket, and finally adjust the distance between the first moving block and the fixed block fixed on the inner wall of the vertical end of the moving bracket. Activate the electric push rod in the second drive assembly. The push rod pushes the drive block to move horizontally. Since the drive block is fitted with a drive sleeve, and the drive sleeve is hinged to the right side wall of the fixed block through the first connector, the drive sleeve will move smoothly along the drive block axis under the hinge limit of the first connector when the drive block moves. When the drive sleeve moves, the hinge of the second connector drives the push block to slide horizontally along the through hole of the protrusion, which pushes the connecting platform on the outside of the block to move the second moving block synchronously, thus achieving precise adjustment of the distance between the second moving block and the first moving block. Through the coordination of the first and second drive assemblies, the distance between adjacent furrow openers can be flexibly changed to precisely adapt to the licorice planting density and the space required for the growth of associated weeds. The connecting motor in the connecting assembly is activated, driving the rotating gear to rotate. Since the rotating gear meshes with the arc-shaped rack fixed to the inclined end of the connecting frame, and the connecting frame is hinged to the connecting block via a hinge shaft, and the connecting block is fixed to the lower side of the fixed block, the first moving block, and the second moving block, the rotation of the rotating gear will drive the connecting frame to rotate around the hinge center via the arc-shaped rack, thereby causing the furrow opener connected to the lower side of the connecting frame to rotate around the hinge center, changing the furrow opener's soil entry angle. By controlling the rotation direction and rotation angle of the connecting motor, the furrow opening depth of the furrow opener can be precisely adjusted to adapt to the soil depth requirements for licorice planting. After adjusting the spacing and depth, the device can be moved by an external agricultural vehicle traction device or manually pushed. It moves smoothly via the wheels on the outer sides of the connecting strips on both sides of the base. During movement, multiple furrow openers simultaneously enter the soil to create planting trenches that meet the requirements. After furrowing, the control valves of each nozzle are controlled according to actual needs: if it is necessary to keep the planting trench moist to facilitate licorice planting, the control valve of the corresponding nozzle above the trench is opened, and water from the tank is transported to the nozzle through the drain pipe and extension pipe to spray water into the trench for moisture retention; if accompanying weeds need water, the control valve of the nozzle above the area where the accompanying weeds grow is opened; if it is not necessary to supply water to the accompanying weeds, the corresponding control valve is closed, achieving precise allocation of water resources and avoiding waste.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The No. 1 drive component adjusts the distance between the No. 1 moving block and the fixed block, and the No. 2 drive component adjusts the distance between the No. 2 moving block and the No. 1 moving block. This allows for flexible changes in the distance between adjacent furrow openers. The limitations of fixed spacing in traditional furrow openers can be overcome by precisely matching the appropriate density required for licorice planting and adapting to the space requirements for the growth of associated weeds. This avoids competition for nutrients and water between licorice and associated weeds due to improper spacing, or disruption of the ecological balance due to insufficient space for weed growth. This improves the targeting and flexibility of planting operations. 2. The transmission structure connecting the motor, rotating gear, arc rack, and connecting frame can precisely adjust the soil entry angle of the furrow opener, thereby changing the furrow depth. It can precisely control the furrow depth according to the needs of different licorice varieties, different soil conditions, and different growth stages, ensuring that the licorice roots can penetrate deep into the soil to obtain sufficient nutrients and water, laying the foundation for the healthy growth of licorice and improving the survival rate and yield of planting. 3. Multiple nozzles with independent control valves are installed, which can flexibly control the water supply in each area according to actual needs: they can not only supply water to the planting trenches to keep them moist, but also selectively supply water according to the water needs of the accompanying weeds, thus achieving precise allocation of water resources.

The pushing end of the electric push rod 10-5 is fixed with a drive block 10-6, and a drive sleeve 10-7 is slidably sleeved on the drive block 10-6. Connector 10-8 is hinged to the right side of drive sleeve 10-7 via a hinge shaft, and the other end of connector 10-8 is hinged to the right side wall of fixing block 6 via a hinge shaft.

By starting the connecting motor 13-2, the rotating gear 13-3 can be rotated, which will mesh with the arc-shaped rack 13-5 and drive the connecting frame 13-4 to rotate around its rotation center with the connecting block 13-1, thereby adjusting the trenching angle of the trencher 12 and changing the trenching depth.

[0028] When using this invention, the device is connected to an external agricultural vehicle via the connecting buckle 18 on the right side of the base 1. If manual movement is required, the hydraulic push rod 17 is activated to drive the drive platform 16 to move to the right, causing the "U"-shaped movable handle 15 to be exposed, making it easy for the operator to push. When manual movement is not required, the hydraulic push rod 17 is activated to drive the drive platform 16 to move to the left, retracting the movable handle 15 to avoid interference during operation. Sufficient clean water is injected into the water tank 3, and the control valves of each nozzle 5 are checked to ensure they are in the closed state. Start the first drive motor 7-4 in the first drive assembly 7. The motor output drives the drive shaft and the fixed rotating part 7-5 to rotate. Since the rotating part 7-5 is movably sleeved on the connecting rod 7-3 through the lower movable groove, and the connecting rod 7-3 is fixed between the two movable blocks 7-2 on the left and right, and the movable block 7-2 slides through the guide seat 7-1 on the outer wall of the fixed block 6, the rotating part 7-5 will generate a horizontal driving force on the connecting rod 7-3 when it rotates, causing the movable block 7-2 to slide along the guide seat 7-1, and then drive the inverted "L" shaped moving bracket 8 fixed to the movable block 7-2 to move horizontally along the frame groove 1-1 of the base 1. During the movement of the moving bracket 8, the support blocks 14 on the left and right sides of its horizontal end slide along the slide rail on the upper side of the base 1 to realize the smooth guidance and reinforcement of the moving bracket 8, and finally adjust the distance between the first moving block 9 fixed to the inner wall of the vertical end of the moving bracket 8 and the fixed block 6. When the electric push rod 10-5 in the second drive assembly 10 is activated, the push end of the electric push rod 10-5 drives the drive block 10-6 to move horizontally. Since the drive block 10-6 is slidably fitted with a drive sleeve 10-7, and the drive sleeve 10-7 is hinged to the right side wall of the fixed block 6 via a first connector 10-8, when the drive block 10-6 moves, under the hinged limiting action of the first connector 10-8, the drive sleeve 10-7 will move smoothly along the axial direction of the drive block 10-6. When the drive sleeve 10-7 moves... The hinged engagement of the second connector 10-9 drives the push block 10-3 to slide horizontally along the through hole of the protrusion 10-2, and the connecting platform 10-4 on the outside of the push block 10-3 drives the second moving block 11 to move synchronously, thus achieving precise adjustment of the distance between the second moving block 11 and the first moving block 9. Through the coordination of the first drive component 7 and the second drive component 10, the distance between adjacent furrow openers 12 can be flexibly changed to precisely adapt to the planting density of licorice and the space required for the growth of associated weeds. The connecting motor 13-2 in the connecting assembly 13 is activated, driving the rotating gear 13-3 to rotate. Since the rotating gear 13-3 meshes with the arc-shaped rack 13-5 fixed to the inclined end of the connecting frame 13-4, and the connecting frame 13-4 is hinged to the connecting block 13-1 via the hinge shaft, and the connecting block 13-1 is fixed to the lower side of the fixed block 6, the first moving block 9, and the second moving block 11, when the rotating gear 13-3 rotates, it will drive the connecting frame 13-4 to rotate around the hinge center through the arc-shaped rack 13-5, thereby causing the furrow opener 12 connected to the lower side of the connecting frame 13-4 to rotate around the hinge center, changing the soil entry angle of the furrow opener 12. By controlling the rotation direction and rotation angle of the connecting motor 13-2, the furrowing depth of the furrow opener 12 can be precisely adjusted to adapt to the soil depth requirements for licorice planting. After the spacing and depth are adjusted, the plant can be moved by an external agricultural vehicle traction device or manually pushed. It can be moved smoothly by the moving wheels 2 on the outer side of the connecting strips 19 on both sides of the base 1. During the movement, multiple furrow openers 12 are simultaneously inserted into the soil to open furrows, forming planting furrows that meet the requirements. After the furrows are opened, the control valves of each nozzle 5 are controlled according to actual needs: if it is necessary to keep the planting furrows moist to facilitate licorice planting, the control valve of the nozzle 5 above the corresponding furrow is opened, and the water in the water tank 3 is transported to the nozzle 5 through the drain pipe 3-2 and the extension pipe 4 to spray water into the furrows to keep them moist; if the accompanying weeds need water, the control valve of the nozzle 5 above the area where the accompanying weeds grow is opened; if it is not necessary to supply water to the accompanying weeds, the corresponding control valve is closed to achieve precise allocation of water resources and avoid waste.

[0029] Compared with the prior art, the beneficial effects of the present invention are: The first drive component 7 adjusts the distance between the first moving block 9 and the fixed block 6, and the second drive component 10 adjusts the distance between the second moving block 11 and the first moving block 9. This allows for flexible changes in the distance between adjacent furrow openers 12. The limitations of fixed spacing in traditional furrow openers can be overcome by precisely matching the appropriate density required for licorice planting and adapting to the space requirements for the growth of associated weeds. This avoids competition for nutrients and water between licorice and associated weeds due to improper spacing, or disruption of the ecological balance due to insufficient space for weed growth. This improves the targeting and flexibility of planting operations. The transmission structure connecting the motor 13-2, rotating gear 13-3, arc rack 13-5, and connecting frame 13-4 can precisely adjust the soil entry angle of the furrow opener 12, thereby changing the furrow depth. It can precisely control the furrow depth according to the needs of different licorice varieties, different soil conditions, and different growth stages, ensuring that the licorice roots can penetrate deep into the soil to obtain sufficient nutrients and water, laying the foundation for the healthy growth of licorice, and improving the planting survival rate and yield. Multiple nozzles 5 with independent control valves are installed, which can flexibly control the water supply in each area according to actual needs: they can not only supply water to the planting trenches to keep them moist, but also selectively supply water according to the water needs of the accompanying weeds, thus achieving precise allocation of water resources.
