Description

Technical Field

[0001] This invention relates to the field of planting technology, specifically to a vine-burying device and method for grape cultivation. Background Technology

[0002] In grape cultivation, burying the vines is a crucial and somewhat complex task. Traditional vine burying often relies on manual labor or simple mechanical assistance. Manual labor is inefficient, labor-intensive, and makes it difficult to ensure uniformity and depth of burying. Simple machinery, on the other hand, is poorly adaptable to vineyards with different terrains and planting layouts, and cannot meet diverse operational needs.

[0003] A grape vine burying machine with publication number CN219741165U includes a lifting frame, a soil covering device, and a transmission device. The soil covering device is rotatably installed on one side of the lifting frame and connected to the transmission device. The transmission device is connected to the drive mechanism of the agricultural machinery. A soil covering adjustment plate is provided on the upper side of the soil covering device. One end of the soil covering adjustment plate is rotatably connected to the lifting frame. The plate body of the soil covering adjustment plate is movably connected to the lifting frame through a telescopic mechanism.

[0004] A grape vine burying machine with publication number CN202455751U includes a frame, a gearbox, rotary tillers and a traction device installed at the front end of the frame. The gearbox and the rotary tillers are connected by a transmission chain. The machine is characterized by having a belt conveyor for throwing soil installed at the rear end of the frame, and a belt conveyor for conveying soil between the rotary tillers and the belt conveyor installed on the frame. The belt conveyor for throwing soil and the belt conveyor for conveying soil move at 90° to each other.

[0005] With the development of agricultural mechanization, there is an urgent need for a high-efficiency, flexible vine-burying device for grape cultivation that can achieve single-sided and double-sided planting scenarios. Currently, the equipment cannot adjust the distance between the soil covering point and the ridging point to improve the efficiency and quality of vine-burying operations, reduce labor costs, and promote the modernization of the grape cultivation industry.

[0014] The second transmission belt mechanism includes two second pulleys, one of which is located at the output shaft end of the second motor, and the other is located at the input shaft end of the transmission belt. The two second pulleys are meshed with each other and connected by a second toothed belt.

[0015] Furthermore, the first linear motion drive assembly includes a second hydraulic cylinder fixedly mounted on the rear housing and a fixed block fixedly mounted on the soil delivery pipe. The push rod head of the second hydraulic cylinder is fixedly connected to the fixed block. Two or more guide grooves are provided on both sides of the rear housing. Support rollers that cooperate with the guide grooves are rotatably mounted on both sides of the soil delivery pipe. The movement direction of the support rollers in the guide grooves is consistent with the extension and retraction direction of the push rod of the second hydraulic cylinder.

[0016] Furthermore, the soil-spreading hopper structure includes a central shaft, on both sides of which are two soil-spreading hoppers symmetrically distributed with the central shaft as the center. Each soil-spreading hopper is provided with a rotating ring that is connected and rotates in cooperation with the central shaft. The two soil-spreading hoppers are provided with a telescopic connecting belt at the joint of the central shaft, and an angle adjustment structure for driving the angle adjustment of the two soil-spreading hoppers is provided between the two soil-spreading hoppers.

[0017] Furthermore, the angle adjustment structure includes an electric telescopic rod disposed between the two mud hoppers. The lower sides of the two mud hoppers are respectively provided with second hinge seats. The second hinge seats and the mud hoppers are connected to each other by a support spring. The electric telescopic rod adopts a double-axis push rod, and the two push rod heads are respectively connected to the two second hinge seats. A fixed seat is fixedly disposed on the outer side of the electric telescopic rod. Two first guide rods are slidably disposed through the fixed seat in the vertical direction. The upper ends of the two first guide rods are fixedly connected to the central shaft.

[0018] Furthermore, the second linear motion drive assembly includes two parallel second guide rods fixedly disposed on the lower side of the lower hopper. Each second guide rod is slidably disposed on a slider. A fixed seat is rotatably disposed between the two sliders. A third motor for driving the fixed seat to rotate is fixedly disposed on one of the sliders. Electric rope winders are respectively disposed at opposite ends of the two second guide rods.

The push rod head of the first hydraulic cylinder is hinged to the rear housing through a first hinge seat.

[0020] A method for burying grapevines includes the following steps:

[0021] S1: Install the vine-burying device onto the appropriate traction equipment using the hoisting assembly, adjust the cover to the appropriate working angle using the first hydraulic cylinder, check whether the connection of each component is secure, and conduct power-on tests on electrical equipment such as the first motor, second motor, third motor, electric telescopic pole, and electric rope reel to ensure normal operation;

[0022] S2: Start the traction equipment to drive the device forward, and at the same time start the first motor. The plow blades in the plowing structure move with the device and cut into the soil, initially cutting the soil. The rollers of the rotary tillage component drive the rotary tillage blades to rotate, further breaking up the soil clods cut by the plow blades.

[0023] S3: Start the second motor. The conveyor belt of the soil conveying component drives the scraper to rotate, and the soil located at the shovel bucket after rotary tillage is conveyed from bottom to top along the soil conveying pipe to the lower hopper.

[0024] S4: Based on the location of the grapevines, the electric rope reel is used to wind up and unwind the traction rope, driving the soil spreading bucket structure to move horizontally to the appropriate position on the second guide rod; then the electric telescopic rod is used to adjust the opening angle of the two soil spreading buckets, so that the soil is evenly spread from the soil spreading buckets and covers the grapevines to complete the vine burying operation.

[0025] S5: In step S4, the electric telescopic rod can drive the two mud buckets to rotate around the central axis, thereby realizing the conversion of the two mud buckets from a straight state to an angle of less than 180 degrees. When the two mud buckets are in a straight state, the third motor adjusts the angle of the two mud buckets and the second linear movement drive component adjusts the position of the mud buckets, enabling soil to be spread on one side. When the two mud buckets are set in an inverted V position, soil can be spread on both sides simultaneously.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. This device integrates multiple functions such as plowing, rotary tillage, soil delivery, and soil spreading. Through the coordinated operation of each component, it can realize an integrated operation from preliminary soil treatment to burying grapevines. Compared with traditional manual or simple mechanical operation, it greatly improves the efficiency of burying vines, reduces operation time, and can adjust the distance between the soil covering point and the ridging point as needed.

[0028] 2. The soil delivery pipe can be adjusted in the tilt direction within the casing via the first linear motion drive component, and the soil spreading hopper structure can be adjusted in both horizontal displacement and angle via the second linear motion drive component. These adjustment functions enable the device to precisely control the location and range of soil delivery and spreading based on factors such as the actual distribution of grapevines, planting row spacing, and terrain, ensuring uniform soil coverage of the grapevines and improving the quality of vine burying.

[0029] 3. The casing adopts an integrated front and rear shell with reinforcing ribs to enhance the overall structural strength and rigidity; each transmission component, such as the first transmission belt mechanism and the second transmission belt mechanism, has the advantages of stable transmission ratio, high efficiency, and shock absorption, 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.

[0030] 4. Multiple components of the device can be flexibly adjusted. For example, the soil spreading hopper structure can realize a variety of soil spreading modes, such as single-side soil spreading and double-side simultaneous soil spreading, which can meet different planting layouts and vine burying requirements. The angle of the cover can be adjusted by the hoisting component to adapt to different terrain conditions and operate normally in complex vineyard environments. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0041] See Figures 1-7 As shown, the present invention provides a vine-burying device for grape cultivation, including a cover 1. A hoisting assembly 2 for hoisting and angle adjustment is provided on the upper side of the cover 1. A plowing structure 3 for cutting soil, a rotary tillage assembly 4 for breaking soil clods, and a soil conveying pipe 5 for conveying the crushed soil from bottom to top at an angle are arranged sequentially on the lower side of the cover 1. A soil conveying assembly 6 is provided inside the soil conveying pipe 5 to provide driving force for conveying the soil from bottom to top at an angle. A first linear motion drive assembly 7 is provided on the cover 1 for driving the soil conveying pipe 5 to move and adjust in the inclined direction inside. A soil spreading hopper structure 8 is provided at the upper end of the soil conveying pipe 5. A second linear motion drive assembly 9 is provided on the soil conveying pipe 5 for adjusting the horizontal displacement of the soil spreading hopper structure 8.

[0042] See instruction manual attached Figure 1 , Figure 4 and Figure 7 As shown, the front shell 101 and the rear shell 102 are integrally formed to form the cover 1, which is the basic load-bearing structure of the entire device. The front shell 101 and the rear shell 102 provide installation space for components such as the plowing structure 3, the rotary tillage component 4, and the soil delivery pipe 5, and protect the internal components from external interference and damage.

[0043] The front housing 101 and the rear housing 102 are connected to the lifting assembly 2 to enable the lifting and angle adjustment of the device. Reinforcing ribs 103 protrude from the upper sides of the front housing 101 and the rear housing 102, enhancing the overall structural strength and rigidity of the housing 1. During operation, especially in high-stress operations such as plowing and rotary tillage, this reduces the risk of deformation of the housing 1, ensuring the stability and reliability of the device and extending its service life. Two or more fixing rods 302 are provided, with both ends fixedly connected to the inner wall of the housing 1, providing a support base for the plow blades 301. Their parallel arrangement ensures that the plow blades 301 are arranged orderly on the same plane, guaranteeing the consistency and continuity of plowing operations.

[0044] The plow blade 301 is slidably mounted on the fixed rod 302. During operation, it cuts into the soil, performing preliminary cutting, breaking up the surface layer, and loosening the soil to create conditions for further soil pulverization and vine burying operations by the rotary tillage component 4. The width of the plowed area can be adjusted by sliding it on the fixed rod 302 to adapt to different soil textures, grape planting row spacing, and other practical conditions. The set bolt 303 is threadedly connected to the plow blade 301. After the plow blade 301 is adjusted to the appropriate position on the fixed rod 302, tightening the set bolt 303 securely fixes the plow blade 301 to the fixed rod 302. This prevents the plow blade 301 from shifting due to soil resistance and other factors during operation, ensuring the accuracy and stability of the plowing operation.

[0045] See instruction manual attached Figure 3 , Figure 4 and Figure 6 As shown, the roller 404, as the core supporting component of the rotary tillage assembly 4, is rotatably mounted inside the casing 1, providing a mounting carrier for the rotary tillage blades 405. Through its own rotation, it drives the rotary tillage blades 405 to perform circular motion around its axis, achieving soil breaking operations.

[0046] Several rotary tillers 405 are evenly distributed in groups on the roller 404, centered on its axis. During operation, as the roller 404 rotates, they cut into the soil clods initially cut by the tilling structure 3 at high speed. Through rapid cutting and impact, the soil clods are further broken up, refining the soil particles, improving soil looseness and aeration, creating more suitable soil conditions for grapevine growth, and facilitating subsequent soil delivery and vine burying operations.

[0047] The first motor 401, serving as the power source for the rotary tiller assembly 4, is fixedly mounted on the housing 1. It provides power to the entire rotary tiller assembly 4 through the rotation of its output shaft. The first pulley 402 and the first toothed belt 403 form the first transmission belt mechanism. One 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 with and connects the two 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 advantages such as stable transmission ratio, high transmission efficiency, and the ability to buffer and absorb vibrations, ensuring the stable and efficient operation of the rotary tiller blades 405. It also helps to prevent damage to the motor and roller 404 due to overload or other conditions.

[0048] See instruction manual 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, and its main function is to collect the broken soil processed by the plowing structure 3 and the rotary tillage component 4. During the movement 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.

[0049] The lower soil hopper 501 is located at the upper end of the soil delivery pipe 5 and serves as a transfer hub in the soil transportation process. It receives soil transported from the soil delivery pipe 5 by the soil delivery assembly 6 and temporarily stores this soil, providing a stable soil supply for the soil spreading hopper structure 8. At the same time, the lower soil hopper 501 also serves as the mounting carrier for the soil spreading hopper structure 8 and the second linear motion drive assembly 9, playing a connecting and supporting role.

[0050] 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 soil hopper 501, ensuring that the soil can be transported along the predetermined path.

[0051] 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 together with the conveyor belt 601, which can effectively scrape the soil in the shovel bucket 502 and prevent the soil from slipping during the movement, ensuring that the soil can be smoothly transported to the lower shovel bucket 501, thus improving the efficiency and stability of soil transportation.

[0052] The second motor 603, mounted on the lower hopper 501, is the power source for the soil conveying assembly 6. It provides driving force to the conveyor belt 601 through the rotation of its output shaft. The speed and torque of the second motor 603 determine the operating speed and conveying capacity of the conveyor belt 601. A second motor 603 with appropriate power and performance can be selected according to actual operational needs to ensure the efficiency and stability of soil conveying.

[0053] The second pulley 605 and the second toothed belt 604 form the second transmission belt mechanism. One second pulley 605 is installed on the output shaft of the second motor 603, and the other is installed on the input shaft of the transmission belt 601. The second toothed belt 604 meshes with 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 transmission belt 601. This transmission method has advantages such as stable transmission ratio, high transmission efficiency, and the ability to buffer and absorb vibrations, ensuring the stable and efficient operation of the transmission belt 601, while also preventing damage to the motor and transmission belt due to overload or other conditions to a certain extent.

[0054] The soil-spreading hopper structure 8 is installed on the lower soil hopper 501, and its function is to evenly spread the soil in the lower soil hopper 501 onto the grapevines. By adjusting its own structure, such as the electric telescopic rod 808 adjusting the opening angle of the two soil-spreading hoppers 802, the spreading range and uniformity of the soil can be controlled to meet the needs of different grapevine burying operations.

[0055] The second linear motion drive assembly 9 is also installed on the lower soil bucket 501, mainly used to adjust the horizontal position of the soil spreading hopper structure 8. By using the electric rope reel 903 to wind and unwind the traction rope 904, the slider 901 is pulled to slide on the second guide rod 902, thereby driving the soil spreading hopper structure 8 to move horizontally, achieving precise adjustment of the soil spreading position and ensuring that the soil can be accurately covered on the grapevines.

[0056] See instruction manual attached Figure 3 As shown, the second hydraulic cylinder 701 is fixedly mounted on the rear housing 102 and is the power core of the first linear motion drive assembly 7. The hydraulic system controls the extension and retraction of the push rod, generating linear driving force. When the push rod extends or retracts, it pushes the connected earth-delivering pipe 5 to move in a specific direction, providing a power source for adjusting the position of the earth-delivering pipe 5.

[0057] The fixing block 702 is fixedly installed on the soil delivery pipe 5 and is used to connect to the push rod head of the second hydraulic cylinder 701. It serves to transmit the thrust of the second hydraulic cylinder 701, ensuring that the soil delivery pipe 5 can move accordingly following the movement of the second hydraulic cylinder 701.

[0058] Guide grooves 703 are formed on both side walls of the rear housing 102, with two or more grooves in total. Their function is to provide a guiding path for the movement of the soil delivery pipe 5, constraining its direction of movement so that it can only move along a trajectory consistent with the extension and retraction direction of the push rod of the second hydraulic cylinder 701. Simultaneously, the guide grooves 703 also enhance the stability of the soil delivery pipe 5 during movement, preventing it from deviating or swaying. Support rollers 704 are rotatably mounted on both sides of the soil delivery pipe 5, cooperating with the guide grooves 703. When the soil delivery pipe 5 moves, the support rollers 704 roll within the guide grooves 703, converting the sliding friction between the soil delivery pipe 5 and the rear housing 102 into rolling friction, greatly reducing movement resistance and making the movement of the soil delivery pipe 5 smoother and more flexible. Furthermore, the support rollers 704 also share some 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.

[0059] See instruction manual attached Figure 4 , Figure 5 and Figure 6 As shown, the soil-spreading hopper structure 8 includes a central shaft 801, with two soil-spreading hoppers 802 symmetrically distributed on both sides of the central shaft 801. Each soil-spreading hopper 802 is provided with a rotating ring 803 that is connected and rotates in cooperation with the central shaft 801. A telescopic connecting belt 805 is provided at the joint of the two soil-spreading hoppers 802 with the central shaft 801. An angle adjustment structure for driving the angle adjustment of the two soil-spreading hoppers 802 is provided between the two soil-spreading hoppers 802. The angle adjustment structure includes an electric telescopic rod 808 positioned between two soil-spreading hoppers 802. Second hinge seats 811 are respectively located on the lower side of each of the two soil-spreading hoppers 802. Support springs 806 connect the second hinge seats 811 to the soil-spreading hoppers 802. The electric telescopic rod 808 employs a double-axis push rod, with the two push rod ends respectively connected to the two second hinge seats 811. A fixed base 807 is fixedly mounted on the outer side of the electric telescopic rod 808. Two first guide rods 809 are slidably mounted through the fixed base 807 in the vertical direction. The upper ends of the two first guide rods 809 are fixedly connected to a central shaft 801. Through this specific structural design, the soil-spreading hopper structure 8 achieves flexible and precise adjustment of the soil-spreading angle and range through the coordinated operation of its components. The central shaft 801 and the rotating ring 803 provide the base for rotation. The electric telescopic rod 808 drives the soil-spreading hopper 802 to rotate. The telescopic connecting belt 805 ensures the integrity of the connection. Components such as the support spring 806, the fixed seat 807, and the first guide rod 809 assist in achieving stable and precise angle adjustment. Based on the actual situation such as the planting layout of the grapevines and the requirements for burying the 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 burying operation and meeting the needs of grape cultivation in different scenarios.

[0060] The second guide rod 902 is fixedly installed on the lower side of the soil hopper 501 and is distributed in parallel, providing a guide track for the movement of the slider 901. Its rigid structure ensures the linearity and stability 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.

[0061] The slider 901 is slidably mounted 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, the fixed base 807 and the soil-spreading hopper structure 8 as a whole are moved horizontally, thereby adjusting 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 structural stability.

[0062] The fixed base 807 is rotatably positioned between the two sliders 901, providing a mounting support point for the soil-spreading hopper structure 8. It is connected to components such as the electric telescopic rod 808 within the soil-spreading hopper structure 8, allowing the soil-spreading hopper structure 8 to be fixed onto the sliders 901. Furthermore, the fixed base 807 can rotate under the drive of the third motor 804, adjusting the soil-spreading hopper structure 8 to adjust the soil-spreading direction and, when the two hoppers 802 are aligned at 180 degrees, adjusting their tilt angle to facilitate the tilting and sliding of soil. The third motor 804 is fixedly mounted on one of the sliders 901, serving as the power source for driving the rotation of the fixed base 807. The rotation of the output shaft drives the fixed base 807 to rotate, thereby causing the soil-spreading hopper structure 8 to change its angle around the rotation center of the fixed base 807. The soil-spreading direction can be precisely adjusted according to the actual vine-burying requirements, ensuring that the soil covers the appropriate area of ​​the grapevines.

[0063] Electric rope winders 903 are respectively installed at opposite ends of the two second guide rods 902. The two electric rope winders 903 work together to wind and unwind the traction rope 904 to drive the slider 901 to slide on the second guide rods 902. The electric rope winders 903 can precisely control the winding and unwinding length of the traction rope 904, thereby achieving precise adjustment of the displacement distance of the slider 901, and thus accurately adjusting the horizontal position of the soil spreading hopper structure 8.

[0064] One end of the traction rope 904 is connected to the electric rope reel 903, and the other end is fixed to the corresponding slider 901, serving to transmit power to the electric rope reel 903. When the electric rope reel 903 winds up or unwinds the traction rope 904, the traction 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 traction rope 904 has a certain degree of flexibility, which can adapt to the movement requirements of the slider 901 and ensure the stability of power transmission.

[0065] See instruction manual attached Figure 3 and Figure 4 As shown, the hoisting assembly 2 includes two parallel lifting rods 202. The lower ends of the two lifting rods 202 are rotatably connected to the two sides of the housing 1, respectively. The upper ends of the two lifting rods 202 are fixedly connected to a crossbeam 201. One end of a support rod 205 is fixedly connected to the crossbeam 201.

[0066] Working principle and technical effects of the present invention:

[0067] The vine-burying device is installed onto a suitable traction device using the hoisting assembly 2. The cover 1 is adjusted to a suitable working angle using the first hydraulic cylinder 203. The connection of each component is checked for stability. The electrical equipment, including the first motor 401, the second motor 603, the third motor 804, the electric telescopic rod 808, and the electric rope winder 903, is tested to ensure normal operation. The traction device is started to move the device forward, and the first motor 401 is turned on. The plow blade 301 in the plowing structure 3 moves with the device and cuts into the soil, initially cutting the soil. The roller 404 of the rotary tillage assembly 4 drives the rotary tillage blade 405 to rotate, further breaking up the soil clods cut by the plow blade 301. The second motor 603 is started, and the conveyor belt 601 of the soil conveying assembly 6 drives the scraper 602 to rotate, transporting the soil located at the shovel bucket 502 after rotary tillage from bottom to top along the soil conveying pipe 5. The soil is fed to the lower hopper 501; according to the position of the grapevine, the electric rope reel 903 winds up and unwinds the traction rope 904, driving the soil spreading hopper structure 8 to move horizontally to a suitable position on the second guide rod 902; then the electric telescopic rod 808 adjusts the opening angle of the two soil spreading hoppers 802, so that the soil is evenly spread from the soil spreading hoppers 802, covering the grapevines to complete the vine burying operation; the electric telescopic rod 808 can drive the two soil spreading hoppers 802 to rotate around the central shaft rod 801, thereby realizing the conversion of the two soil spreading hoppers 802 from a straight state to an angle of less than 180 degrees. When the two soil spreading hoppers 802 are in a straight state, the third motor 804 adjusts the angle of the two soil spreading hoppers 802 and the second linear movement drive component 9 adjusts the position of the soil spreading hoppers 802, which can realize soil spreading on one side. When the two soil spreading hoppers 802 are set in an inverted V position, soil spreading on both sides can be realized simultaneously.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
