[0011] Furthermore, the first linear movement driving assembly includes a second hydraulic cylinder fixedly arranged on the rear housing and a fixed block fixedly arranged on the soil delivery pipe. The push rod head end of the second hydraulic cylinder is fixedly connected to the fixed block. More than two guiding chutes are opened on both side walls of the rear housing. Support rollers are rotatably arranged on both sides of the soil delivery pipe and are matched with the guiding chutes. The moving direction of the support rollers in the guiding chutes is consistent with the telescopic direction of the push rod of the second hydraulic cylinder.

[0012] Furthermore, the soil spreading hopper structure includes a central shaft rod. Two soil sliding hoppers symmetrically distributed with the central shaft rod as the center are arranged on both sides of the central shaft rod. A rotating ring that is rotatably connected with the central shaft rod is arranged on each soil sliding hopper. A telescopic connecting belt is arranged at the docking part of the two soil sliding hoppers on the central shaft rod. An angle adjusting structure for driving the angle adjustment of the two soil sliding hoppers is arranged between the two soil sliding hoppers.

[0013] Furthermore, the angle adjusting structure includes an electric telescopic rod arranged between the two soil sliding hoppers.

[0014] Furthermore, the second linear movement driving assembly includes two second guiding rods arranged in parallel and fixedly arranged on the lower side of the lower soil hopper. A slider is slidably arranged on each second guiding rod. The fixed seat is rotatably arranged between the two sliders.

[0016] A method for burying grape vines for grape planting includes the following steps: S1: Install the vine burying device on a suitable traction device through the hoisting assembly, use the first hydraulic cylinder to adjust the housing to a suitable working angle, check whether the connections of all components are firm, and conduct power-on tests on electrical equipment such as the first motor, the second motor, the third motor, the electric telescopic rod, and the electric rope winder to ensure normal operation; S2: Start the traction device to drive the device forward, and at the same time turn on the first motor. The plow blades in the plowing structure cut into the soil as the device moves, initially cutting the soil; the roller shafts of the rotary tillage components drive the rotary tillage blades to rotate, further crushing the soil blocks cut by the plow blades; S3: Start the second motor. The conveyor belt of the soil delivery and conveying component drives the soil scraping plate to operate, and conveys the soil located at the soil shovel bucket after rotary tillage along the soil delivery pipeline from bottom to top and obliquely upward to the lower soil bucket; S4: According to the position of the grapevine, use the electric winch to take in and release the traction rope, and drive the soil spreading hopper structure to horizontally move to a suitable position on the second guide rod; then adjust the opening angle of the two soil hoppers through the electric telescopic rod, so that the soil is evenly spread out from the soil hoppers and covers the grapevine to complete the grapevine burying operation; S5: In step S4, the electric telescopic rod can drive the two soil hoppers to rotate around the central shaft rod, so as to realize the conversion of the two soil hoppers from a straight state to an angle less than 180 degrees. When the two soil hoppers are in a straight state, under the angle adjustment of the two soil hoppers by the third motor and the position adjustment of the soil hoppers by the second linear movement driving component, single-sided soil spreading can be realized. When the two soil hoppers are arranged in an inverted V shape, bilateral soil spreading can be realized simultaneously.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The device integrates multiple functions such as plowing, rotary tillage, soil delivery, and soil spreading. Through the coordinated operation of each component, it can realize the integrated operation from the initial soil treatment to the grapevine soil covering. Compared with traditional manual or simple mechanical operations, it greatly improves the efficiency of the grapevine burying operation, reduces the operation time, and can adjust the distance between the soil covering point and the ridging position according to needs.

[0019] 2. The soil delivery pipeline can be adjusted in the inclined direction in the housing through the first linear movement driving component, and the soil spreading hopper structure can realize horizontal displacement adjustment and angle adjustment through the second linear movement driving component. The above adjustment functions enable the device to accurately control the conveying and spreading position and range of the soil according to factors such as the actual distribution of the grapevines, the planting row spacing, and the terrain, ensuring that the soil evenly covers the grapevines and improving the quality of grapevine burying.

[0020] 3. The housing adopts an integrally formed front housing and rear housing, and is provided with reinforcing ribs, enhancing the overall structural strength and rigidity; each transmission component such as the first conveyor belt mechanism, the second conveyor belt mechanism, etc. has the advantages of stable transmission ratio, high efficiency, and the ability to buffer and absorb vibration, ensuring the stability and reliability of the device during long-term operation, reducing the probability of failure, and extending the service life of the equipment.

[0021] 4. Multiple components of the device can be flexibly adjusted. For example, the soil spreading hopper structure can achieve multiple soil spreading modes, such as single-side soil spreading and simultaneous bilateral soil spreading, etc., which can meet different planting layouts and vine burying requirements; the angle of the housing can be adjusted through the hoisting component to adapt to different terrain conditions and can also operate normally in complex vineyard environments.

Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present invention.

[0026] See Figures 1-7 As shown, the present invention provides a grapevine burying device for grape planting, which includes a housing 1. A lifting assembly 2 for lifting and angle adjustment is arranged on the upper side of the housing 1. A plowing structure 3 for cutting soil, a rotary tillage assembly 4 for crushing soil clods, and a soil delivery pipe 5 for obliquely upward conveying the crushed soil from bottom to top are sequentially arranged on the lower side inside the housing 1. A soil delivery and conveying assembly 6 for providing driving force for the upward oblique conveyance of soil in it is arranged inside the soil delivery pipe 5. A first linear movement driving assembly 7 for driving the soil delivery pipe 5 to move and adjust in its inclination direction is arranged on the housing 1. A soil spreading hopper structure 8 is arranged at the upper end of the soil delivery pipe 5. A second linear movement driving assembly 9 for adjusting the horizontal displacement of the soil spreading hopper structure 8 is arranged on the soil delivery pipe 5.

[0027] See the appended specification Figure 1 、 Figure 4 andFigure 7 As shown in the figure, both the front housing 101 and the rear housing 102 are integrally formed to constitute the housing 1, which is the basic load-bearing structure of the entire device. The front housing 101 and the rear housing 102 provide an installation site for components such as the plowing structure 3, the rotary tillage assembly 4, and the soil delivery pipeline 5, protecting the internal components from external interference and damage.

[0028] The front housing 101 and the rear housing 102 cooperate with the lifting assembly 2 to achieve the lifting and angle adjustment of the device. The reinforcing ribs 103 are convexly arranged on the upper sides of the front housing 101 and the rear housing 102, which can enhance the overall structural strength and rigidity of the housing 1. When the device is working, especially during operations with large forces such as plowing and rotary tillage, the risk of deformation of the housing 1 can be reduced, ensuring the stability and reliability of the device and extending its service life. More than two fixing rods 302 are provided and both ends are respectively fixedly connected to the inner side wall of the housing 1, providing an installation and support basis for the plow blades 301. Their parallel distribution ensures that the plow blades 301 are arranged in an orderly manner on the same plane, guaranteeing the consistency and continuity of the plowing operation.

[0029] The plow blades 301 are slidably arranged on the fixing rods 302. During operation, they cut into the soil, making a preliminary cut of the soil, breaking the soil surface layer, and loosening the soil, creating conditions for the subsequent rotary tillage assembly 4 to further break up the soil and the vine burying operation. By sliding and adjusting the position on the fixing rods 302, the width of plowing can be changed to adapt to actual situations such as different soil textures and grape planting row spacings. The set screws 303 are threadedly connected to the plow blades 301. When the plow blades 301 are adjusted to the appropriate position on the fixing rods 302, the set screws 303 are tightened to firmly fix the plow blades 301 on the fixing rods 302, preventing the plow blades 301 from shifting due to factors such as soil resistance during operation and ensuring the accuracy and stability of the plowing operation.

[0030] See the attached Figure 3 、 Figure 4 and Figure 6 As shown in the figure, the roller shaft 404, as the core support component of the rotary tillage assembly 4, is rotatably arranged in the housing 1, providing an installation carrier for the rotary tillage blades 405. Through its own rotation, it drives the rotary tillage blades 405 to perform a circular motion around its axis, achieving the operation of breaking up the soil.

[0031] A number of rotary tillage blades 405 are evenly distributed in several groups with the axis of the roller shaft 404 as the center and installed on the roller shaft 404. During operation, as the roller shaft 404 rotates, they cut into the soil blocks that have been preliminarily cut by the plowing structure 3 at high speed. Through methods such as rapid cutting and impact, the soil blocks are further broken up, making the soil particles finer, improving the looseness and air permeability of the soil, creating more suitable soil conditions for the growth of grapevines, and also facilitating subsequent soil delivery and vine burying operations.

[0032] The first motor 401 serves as the power source of the rotary tillage assembly 4 and is fixedly mounted on the housing 1. The rotation of the output shaft provides power to the entire rotary tillage assembly 4. The first pulley 402 and the first toothed belt 403 form a first transmission belt mechanism, wherein one first pulley 402 is mounted on the output shaft end of the first motor 401, and the other is mounted on the shaft end of the roller 404. The first toothed belt 403 meshes and connects the two first pulleys 402. Together, they constitute a transmission system that smoothly and reliably transmits the power of the first motor 401 to the roller 404. This transmission method has the advantages of stable transmission ratio, high transmission efficiency, and the ability to buffer and absorb vibrations, thereby ensuring the stable and efficient operation of the rotary tillage blade 405. At the same time, it can, to a certain extent, avoid damage to the motor and roller due to overload and other conditions.

[0033] See the instructions attached Figure 2 、 Figure 4 and Figure 6 As shown, the shovel bucket 502 is located at the lower end of the soil delivery pipe 5. Its main function is to collect the crushed soil processed by the plowing structure 3 and the rotary tillage assembly 4. During the operation of the device, the shovel bucket 502, with its unique triangular tip shape and position, can effectively gather the soil on the ground and guide it into the soil delivery pipe 5, providing a stable soil source for subsequent soil transportation.

[0034] The lower soil bucket 501, located at the upper end of the soil delivery pipe 5, serves as a transfer hub during soil transportation. It receives soil delivered from the soil delivery assembly 6 within the soil delivery pipe 5 and temporarily stores this soil, providing a stable supply of soil to the spreading hopper structure 8. Furthermore, the lower soil bucket 501 serves as a mounting support for the spreading hopper structure 8 and the second linear motion drive assembly 9, providing both connection and support.

[0035] The conveyor belt 601 is installed inside the soil delivery pipe 5 and is the core component of the soil delivery assembly 6. Driven by the second motor 603, the conveyor belt 601 undertakes the important task of transporting soil from the lower end of the soil delivery pipe 5 to the upper end of the lower soil bucket 501, ensuring that the soil can be transported along the predetermined path.

[0036] The scraper blades 602 are evenly distributed on the outer surface of the conveyor belt 601 along the conveying direction. When the conveyor belt 601 is running, the scraper blades 602 move with the conveyor belt 601, effectively scraping the soil in the shovel bucket 502 and preventing the soil from sliding during movement, ensuring that the soil can be smoothly transported to the lower shovel bucket 501, thereby improving the efficiency and stability of soil transportation.

[0037] The second motor 603 is installed on the lower soil bucket 501 and is the power source of the soil delivery and conveying assembly 6. It provides driving force for the conveyor belt 601 through the rotation of the output shaft. The rotational speed and torque of the second motor 603 determine the running speed and conveying capacity of the conveyor belt 601. A second motor 603 with appropriate power and performance can be selected according to the actual operation requirements to ensure the efficiency and stability of soil conveyance.

[0038] The second pulley 605 and the second toothed belt 604 form the second conveyor belt mechanism. One second pulley 605 is installed at the end of the output shaft of the second motor 603, and the other is installed at the input shaft end of the conveyor belt 601. The second toothed belt 604 meshes and connects the two second pulleys 605. Together, they constitute a transmission system that smoothly and reliably transmits the power of the second motor 603 to the conveyor belt 601. This transmission method has the advantages of stable transmission ratio, high transmission efficiency, and the ability to buffer and absorb vibration, ensuring the stable and efficient operation of the conveyor belt 601, and at the same time, it can avoid damage to the motor and conveyor belt to a certain extent due to overload and other situations.

[0039] The soil spreading hopper structure 8 is installed on the lower soil bucket 501, and its function is to evenly spread the soil in the lower soil bucket 501 on the grapevines. By adjusting its own structure, such as using the electric telescopic rod 808 to adjust the opening angle of the two soil sliding hoppers 802, the spreading range and evenness of the soil can be controlled to meet the requirements of different grapevine burying operations.

[0040] The second linear movement driving assembly 9 is also installed on the lower soil bucket 501 and is mainly used to adjust the horizontal position of the soil spreading hopper structure 8. By winding and unwinding the towing rope 904 with the electric winch 903, the slider 901 is pulled to slide on the second guide rod 902, thereby driving the soil spreading hopper structure 8 to move horizontally, realizing precise adjustment of the soil spreading position, and ensuring that the soil can accurately cover the grapevines.

[0041] See the attached Figure 3 As shown, the second hydraulic cylinder 701 is fixedly arranged on the rear housing 102 and is the power core of the first linear movement driving assembly 7. Through the hydraulic system, the telescopic movement of the push rod is controlled to generate a linear driving force. When the push rod extends or retracts, it pushes the soil delivery pipe 5 connected thereto to move in a specific direction, providing a power source for the position adjustment of the soil delivery pipe 5.

[0042] The fixing block 702 is fixedly arranged on the soil delivery pipe 5 and is used to connect the head end of the push rod of the second hydraulic cylinder 701. It plays a role in transmitting the thrust of the second hydraulic cylinder 701, ensuring that the soil delivery pipe 5 can move correspondingly following the action of the second hydraulic cylinder 701.

[0043] The guiding sliding grooves 703 are opened on the two side walls of the rear housing 102, and the number is more than two. Its function is to provide a guiding path for the movement of the soil delivery pipe 5, restrict the movement direction of the soil delivery pipe 5, so that it can only move along the trajectory consistent with the telescopic direction of the push rod of the second hydraulic cylinder 701. At the same time, the guiding sliding grooves 703 can also enhance the stability of the soil delivery pipe 5 during movement to a certain extent, preventing it from shifting or shaking during the movement. The supporting rollers 704 are rotatably arranged on both sides of the soil delivery pipe 5 and cooperate with the guiding sliding grooves 703. When the soil delivery pipe 5 moves, the supporting rollers 704 roll in the guiding sliding grooves 703, converting the sliding friction between the soil delivery pipe 5 and the rear housing 102 into rolling friction, greatly reducing the movement resistance and making the movement of the soil delivery pipe 5 smoother and more flexible. In addition, the supporting rollers 704 also share part of the weight of the soil delivery pipe 5, reducing the pressure between it and the rear housing 102, reducing component wear and extending the service life of the equipment.

[0044] See the attached drawings of the specification Figure 4 , Figure 5 and Figure 6 As shown in the figure, the soil spreading hopper structure 8 includes a central shaft rod 801. On both sides of the central shaft rod 801, there are two soil sliding hoppers 802 symmetrically distributed around it. Each soil sliding hopper 802 is provided with a rotating ring 803 that is connected and rotates with the central shaft rod 801. At the docking part of the two soil sliding hoppers 802 on the central shaft rod 801, there is a telescopic connecting belt 805. Between the two soil sliding hoppers 802, there is an angle adjustment structure for driving the angle adjustment of the two. The angle adjustment structure includes an electric telescopic rod 808 arranged between the two soil sliding hoppers 802. On the lower sides of the two soil sliding hoppers 802, there are respectively second hinge seats 811. The second hinge seats 811 and the soil sliding hoppers 802 are connected to each other by support springs 806. The electric telescopic rod 808 uses a double-axis push rod and the head ends of the two push rods are respectively connected to the two second hinge seats 811. A fixed seat 807 is fixedly arranged on the outside of the electric telescopic rod 808. Two first guide rods 809 are slidably arranged through the fixed seat 807 in the up and down direction. The upper ends of the two first guide rods 809 are fixedly connected to the central shaft rod 801. Through the above specific structural design, the soil spreading hopper structure 8 realizes flexible and precise adjustment of the soil spreading angle and range through the coordinated work of each component. The central shaft rod 801 and the rotating ring 803 provide a rotation basis, the electric telescopic rod 808 drives the soil sliding hopper 802 to rotate, the telescopic connecting belt 805 ensures the connection integrity, and components such as the support springs 806, the fixed seat 807 and the first guide rods 809 assist in realizing stable and precise angle adjustment. According to the actual situations such as the planting layout of grapevines and the requirements for burying vines, the soil spreading hopper structure 8 can be adjusted to evenly and accurately spread the soil on the grapevines, improving the efficiency and quality of the vine burying operation and meeting the grape planting needs in different scenarios.

[0045] The second guide rod 902 is fixedly arranged on the lower side of the lower soil hopper 501 and is distributed in parallel, providing a guiding track for the movement of the slider 901. Its rigid structure ensures the linearity and stability of the movement of the slider 901 in the horizontal direction, restricting the slider 901 to slide only along the axial direction of the second guide rod 902, thereby precisely controlling the horizontal displacement direction of the soil spreading hopper structure 8.

[0046] The slider 901 is slidably arranged on the second guide rod 902 and is a key component connecting the second guide rod 902 and the soil spreading hopper structure 8. By sliding on the second guide rod 902, it drives the fixed seat 807 and the entire soil spreading hopper structure 8 to move horizontally, realizing the adjustment of the soil spreading position. At the same time, the slider 901 also bears part of the weight of the soil spreading hopper structure 8 and the forces generated during operation, ensuring the structural stability.

[0047] The fixed seat 807 is rotatably arranged between the two sliders 901, providing an installation support point for the soil spreading hopper structure 8. It is connected to components such as the electric telescopic rod 808 in the soil spreading hopper structure 8, enabling the soil spreading hopper structure 8 to be fixed on the slider 901. In addition, the fixed seat 807 can be rotated under the drive of the third motor 804, driving the soil spreading hopper structure 8 to adjust the soil spreading direction and realizing the tilt angle adjustment when the two soil hoppers 802 are in a 180-degree straight state, facilitating the inclined sliding of the soil. The third motor 804 is fixedly arranged on one of the sliders 901 and serves as the power source for driving the rotation of the fixed seat 807. Through the rotation of the output shaft, it drives the fixed seat 807 to rotate, and then the soil spreading hopper structure 8 changes the angle around the rotation center of the fixed seat 807. The soil spreading direction can be precisely adjusted according to the actual needs of vine burying to ensure that the soil can cover the appropriate position of the grapevine.

[0048] The electric rope winders 903 are respectively arranged at the opposite ends of the two second guide rods 902. The two electric rope winders 903 cooperate to wind and unwind the towing rope 904 to drive the slider 901 to slide on the second guide rod 902. The electric rope winder 903 can precisely control the winding and unwinding length of the towing rope 904, thereby realizing the precise adjustment of the displacement distance of the slider 901, and then precisely adjusting the horizontal position of the soil spreading hopper structure 8.

[0049] One end of the towing rope 904 is connected to the electric rope winder 903, and the other end is fixed to the corresponding slider 901, playing the role of transmitting the power of the electric rope winder 903. When the electric rope winder 903 winds and unwinds the towing rope 904, the towing rope 904 pulls the slider 901 to slide on the second guide rod 902, realizing the horizontal movement of the soil spreading hopper structure 8. At the same time, the towing rope 904 has a certain flexibility, which can adapt to the movement requirements of the slider 901 and ensure the stability of power transmission.

[0050] See the attached instructions Figure 3 andFigure 4 As shown in the figure, the hoisting assembly 2 includes two parallel booms 202. The lower ends of the two booms 202 are respectively rotatably connected to both sides of the housing 1. The upper ends of the two booms 202 are fixedly connected to each other with a cross beam 201. One end of a support rod 205 is fixedly connected to the cross beam 201. The other end of the support rod 205 is hingedly provided with a first hydraulic cylinder 203. The push rod head end of the first hydraulic cylinder 203 is hingedly connected to the rear housing 102 through a first hinge seat 206.

[0051] The working principle and technical effect of the present invention: Install the vine burying device on a suitable traction device through the hoisting assembly 2. Use the first hydraulic cylinder 203 to adjust the housing 1 to a suitable working angle. Check whether the connections of all components are firm. Conduct a power-on test on electrical equipment such as the first motor 401, the second motor 603, the third motor 804, the electric telescopic rod 808, and the electric rope reel 903 to ensure normal operation. Start the traction device to drive the device forward. At the same time, start the first motor 401, and the plow blade 301 in the plowing structure 3 cuts into the soil as the device moves, initially cutting the soil. The roller shaft 404 of the rotary tillage assembly 4 drives the rotary tillage blade 405 to rotate, further crushing the soil blocks cut by the plow blade 301. Start the second motor 603, and the conveyor belt 601 of the soil conveying assembly 6 drives the soil scraping plate 602 to operate, and conveys the soil at the soil shoveling bucket 502 after rotary tillage upward along the soil conveying pipe 5 from bottom to top and obliquely upward to the lower soil bucket 501. According to the position of the grapevine, use the electric rope reel 903 to wind and unwind the traction rope 904, and drive the soil spreading hopper structure 8 to horizontally move to a suitable position on the second guide rod 902. Then, adjust the opening angle of the two soil sliding hoppers 802 through the electric telescopic rod 808, so that the soil is evenly scattered from the soil sliding hoppers 802 to cover the grapevine to complete the vine burying operation. The electric telescopic rod 808 can drive the two soil sliding hoppers 802 to rotate around the central shaft rod 801, so as to realize the conversion of the two soil sliding hoppers 802 from a straight state to an angle less than 180 degrees. When the two soil sliding hoppers 802 are in a straight state, under the angle adjustment of the two soil sliding hoppers 802 by the third motor 804 and the position adjustment of the soil sliding hoppers 802 by the second linear movement driving assembly 9, single-side soil spreading can be realized. When the two soil sliding hoppers 802 are arranged in an inverted V shape, bilateral soil spreading can be realized simultaneously.

[0052] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
