Abstract

The present invention relates to a protective forest and grass cultivation device. The device comprises two parallel, symmetrical, long-span traction assemblies and a protective reel. Each assembly includes a main drive and secondary support assembly. The protective reel deploys and retracts via a combination of ground piles, cross arms, and anti-slip sheaves. Driven by an electric drive mechanism, the reel is adjusted by a tensioning mechanism to adjust the tension of the steel wire rope. This flexible adjustment effectively resists external interference without affecting forest and grass growth, improving the quality and efficiency of forest and grass cultivation and meeting the needs of modern forest and grass cultivation.

Description

Technical Field

[0001] The present invention relates to the field of forest and grass cultivation, and in particular to a forest and grass cultivation device with a protective function. Background Art

[0002] In the current development of ecological and environmental conservation and urban greening, forest and grass cultivation, as a key component, bears the important mission of maintaining ecological balance and beautifying the environment. Whether in urban parks, roadside green belts, or large-scale nurseries, the cultivation and maintenance of forest and grass vegetation has received widespread attention. As people's demands for ecological and environmental quality continue to rise, the scale and sophistication of forest and grass cultivation are also continuously increasing. Traditional artificial cultivation and simple protection methods are no longer able to meet the requirements of modern forest and grass cultivation for efficiency, science, and precision.

[0003] However, in the actual forest and grass cultivation process, especially in lawn and nursery areas, there are many technical problems that need to be solved urgently. On the one hand, these areas are often faced with frequent interference from human or animal activities. For example, park lawns are easily trampled by tourists, and nursery bases will also cause mechanical damage to forests and grasses during daily management and transportation, resulting in impaired forest and grass growth and prolonged recovery periods. On the other hand, existing protective measures, such as fixed fences or simple covering nets, either have poor flexibility and cannot be adjusted according to the different stages and needs of forest and grass cultivation, or have limited protective effects and are difficult to effectively resist external interference. When forests and grasses require growth conditions such as light and ventilation, the protection cannot be lifted in time, affecting the normal growth of forests and grasses. These problems seriously restrict the quality and efficiency of forest and grass cultivation, and there is an urgent need for a cultivation device that can be flexibly adjusted, effectively protected, and does not affect the normal growth of forests and grasses. Summary of the Invention

[0009] Furthermore, the tightening mechanism includes a diamond-shaped end plate fixedly connected to the other ends of the two guide shafts, a long screw passing through the diamond-shaped end plate, and an adapter sleeve. A threaded through hole for the long screw to pass through is opened at the center of the diamond-shaped end plate. A flat portion is formed on the outer wall of the end of the long screw away from the rectangular lifting plate. The adapter sleeve is sleeved on the end of the long screw and fastened to the outside of the flat portion by a top screw. A hexagonal wrench hole is formed on the outer end of the adapter sleeve.

[0010] The two wheels are connected to each other via a first gear and a second gear is connected to each other via a gear train connected to the transmission gear of the said motor; the two wheels are connected to each other via a gear train connected to the transmission gear of the said motor; the two wheels are connected to each other via a gear train connected to the transmission gear of the said motor; and the two wheels are connected to each other via a gear train connected to the transmission gear of the said motor.

[0011] Furthermore, the two beam plates are formed with straight edges perpendicular to the beam plates at one end close to the drive motor, the straight edges of the two beam plates are tightly connected, and a waist hole is provided at the connection between the beam plate and the main drive wheel for the output shaft of the drive motor to slide. The outer sides of the two beam plates are provided with bearings that are sleeved on the output shaft of the drive motor. A U-shaped bracket is also provided on the outer sides of the two beam plates, and the two ends of the U-shaped bracket are respectively sleeved on the outer rings of the two bearings. A second hand-tightened screw is screwed on the top of the U-shaped bracket, and the end of the second hand-tightened screw is pressed against the intersection of the two straight edges.

[0012] Furthermore, a flat plate base is fixedly connected to the bottom of the driving motor, and two spaced-apart raising seats are provided at one end of the flat plate base away from the driving motor. The top of each raising seat is fixedly connected to a bearing seat for connecting to a rotating support shaft, and a handle is fixedly connected to the center of the flat plate base.

[0013] Furthermore, the driving motor adopts a brake motor, and the end of the rotating support shaft that is plugged into the central shaft tube of the protective roll net is provided with a corresponding pin hole, and a locking shaft seat is provided between the two bearing seats. The locking shaft seat is provided with a through hole with a diameter larger than the diameter of the rotating support shaft and an elastic shrinkage gap extending longitudinally and passing through the through hole, and a bolt for loosening or tightening the elastic shrinkage gap is screwed onto the top of the locking shaft seat.

[0014] Furthermore, an oblique support arm is provided between the upper half of the steel pipe and the ground, and an anti-slip tooth plate is hinged at one end of the oblique support arm close to the ground, and an adjustable tensioning rod is provided between the lower end of the oblique support arm and the end of the steel pipe close to the ground.

A dial is provided at the bottom of the cross arm mechanism for driving the first sliding sleeve below to rotate synchronously with it.

[0015] Furthermore, the adjustable tensioning rod includes two symmetrically arranged threaded pull rods and an internally threaded hexagonal prism for screwing the opposite ends of the two threaded pull rods. The outer end of one threaded pull rod is axially connected to the corresponding first sliding sleeve, and the outer end of the other threaded pull rod is axially connected to a second sliding sleeve. The second sliding sleeve is fixedly mounted on the lower end of the oblique support arm.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] First, the protection is flexible and adjustable: existing protection measures such as fixed fences or simple covering nets are not flexible enough and difficult to adjust according to the different stages and needs of forest and grass cultivation. The forest and grass cultivation device with protection function in this solution can easily realize the deployment and folding of the protection net through two sets of large-span traction components and retractable protection nets. When the forest and grass need protection, the protection net can be deployed to resist external interference; when the forest and grass need light, ventilation and other growth conditions, the protection net can be folded in time to meet the normal growth needs of the forest and grass, and the protection status can be flexibly adjusted;

[0018] Second, it effectively resists external interference: Lawns and nurseries in current forest and grass cultivation areas are often disturbed by human or animal activities, and existing protective measures are limited in effectiveness. In this solution, the outermost ends of the protective net are fixedly connected to the steel ropes on both sides, and the tightening mechanism of the secondary support assembly can drive the anti-slip groove wheel to reversely tighten the steel ropes, ensuring that the steel ropes are at the appropriate tension, making the protective net stable and more effectively resisting external interference, reducing the damage to the forest and grass caused by external interference and shortening the recovery period;

[0019] Third, adaptability to different terrains and needs: Traditional forest and grass cultivation methods and protective measures are difficult to adapt to diverse terrains and the refined needs of forest and grass cultivation. In this solution, the steel pipe of the ground pile column mechanism can be flexibly inserted into the cylindrical base pile and fixed with a flange-shaped limit sleeve and radial top screw, allowing flexible height adjustment to adapt to different terrains. The rectangular lifting plate of the cross-arm mechanism can move up and down along the steel pipe and be fixed with a first-hand screw. The height and position of the anti-slip groove wheel can be precisely adjusted to meet the needs of different specifications of protective nets and forest and grass cultivation, improving the adaptability and practicality of the device.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 10 As shown, a forest and grass cultivation device with a protective function includes two groups of parallel and symmetrically arranged large-span traction components 1 and a protective reel 2 located between the two groups of large-span traction components 1, each group of large-span traction components 1 includes a main drive component 3 and an auxiliary support component 4 respectively arranged at the two ends of the nursery in the length or width direction, the main drive component 3 and the auxiliary support component 4 both include a ground pile column mechanism, a cross arm mechanism rotatably arranged at the upper end of the ground pile column mechanism and an anti-skid groove wheel 5 arranged at one end of the cross arm mechanism, the two anti-skid groove wheels 5 are connected by a closed steel wire rope 6 formed by a head-to-tail fixed connection, wherein the auxiliary support component 4 also includes a tightening mechanism for driving the anti-skid groove wheel 5 to reversely tighten the steel wire rope 6, the main drive component 3 also includes an electric drive mechanism for driving its anti-skid groove wheel 5 to rotate and a rotating support shaft 8 for setting up both ends of the central shaft cylinder 7 supporting the protective reel 2, and the outermost ends of the protective reel 2 are fixedly connected to the steel wire rope 6 on both sides.

[0033] Working Principle: The core of this forest and grass cultivation device consists of two sets of large-span traction assemblies 1 and a protective roll net 2. The large-span traction assemblies 1 are arranged along the length or width of the nursery, each with a main drive assembly 3 and auxiliary support assembly 4 at each end. In the main drive assembly 3 and auxiliary support assembly 4, a ground stake mechanism is rooted in the ground to provide stable support. A cross arm mechanism is installed above it for flexible adjustment. An anti-skid sheave 5 is mounted at one end of the cross arm mechanism. The anti-skid sheave 5 of the two assemblies is connected by a closed steel wire rope 6, forming a transmission system. When the electric drive mechanism of the main drive assembly 3 is activated, it drives the anti-skid sheave 5 to rotate, thereby moving the traction wire rope 6. The tensioning mechanism of the auxiliary support assembly 4 adjusts the tension of the wire rope 6 to ensure it is at the appropriate tension. The protective roll net 2 is fixed to the wire rope 6 at both ends. As the wire rope 6 moves, the protective roll net 2 can be expanded or retracted, covering or exposing the forest and grass.

[0034] Purpose and Effect: This design provides flexible protection for forest and grass cultivation areas. The electric drive mechanism drives the steel wire rope 6, which in turn drives the protective net 2, allowing for convenient control of the protection range. The protective net 2 can be deployed when needed to protect the forest and grass, protecting it from adverse external factors such as animal damage and inclement weather; it can be retracted when not needed, facilitating daily management and growth observation of the forest and grass. The tightening mechanism ensures that the steel wire rope 6 is always at the appropriate tension, preventing unstable operation of the protective net 2 due to excessive looseness or damage to equipment components due to excessive tension, thereby improving the reliability and stability of the device.

[0035] The ground pile column mechanism includes a cylindrical bottom pile 9 embedded under the ground surface, a steel pipe 10 movably inserted into the cylindrical bottom pile 9, and a flange-shaped limiting sleeve 11 sleeved on the outside of the steel pipe 10. The flange-shaped limiting sleeve 11 is fixedly connected to the steel pipe 10 by means of radial top screws, and a stepped groove for accommodating the flange-shaped limiting sleeve 11 is formed at the top opening of the cylindrical bottom pile 9.

[0036] Working Principle: The cylindrical base pile 9 of the ground pile column mechanism is pre-buried below the ground surface, providing basic support for the entire device. A steel pipe 10 is movably inserted into the cylindrical base pile 9, allowing its height to be adjusted according to actual needs. A flange-shaped limit sleeve 11 fits over the outer surface of the steel pipe 10 and is secured with radial screws to prevent it from moving up or down. A stepped groove at the top of the cylindrical base pile 9 accommodates the flange-shaped limit sleeve 11, ensuring a more secure installation and simultaneously positioning the steel pipe 10.

[0037] Purpose and Effect: This structural design allows for flexible adjustment of the height of the ground pile column mechanism to suit varying terrain and forest and grass cultivation requirements. For example, in a nursery with uneven terrain, the height of the steel pipe 10 can be adjusted to ensure the cross arm mechanism and anti-skid sheave 5 are properly positioned, ensuring the proper operation of the entire device. The combination of the flange-shaped limit sleeve 11 and the stepped sink trough enhances the stability and reliability of the ground pile column mechanism, preventing the steel pipe 10 from loosening during use and improving the overall safety of the device.

[0038] The cross arm mechanism includes a rectangular lifting plate 12 that is movably sleeved on the upper end of the pile column mechanism in a horizontal state, two guide shafts 13 that are movably penetrated through both sides of the rectangular lifting plate 12 in a horizontal state, and a pulley seat 14 that is fixedly connected to the same end of the two guide shafts 13. The pulley seat 14 is used for axial installation of the corresponding anti-skid groove wheel 5. The length of the guide shaft 13 is greater than the length of one side penetrated by the rectangular lifting plate 12. A center hole for the steel pipe 10 to pass through is formed at the center of the rectangular lifting plate 12. The upper and lower ends of the rectangular lifting plate 12 are fixedly connected with flange positioning sleeves 15 that are coaxial with the center hole. The flange positioning sleeve 15 is slidably sleeved with the outer side of the steel pipe 10. A first hand-tightening screw 16 is screwed on the side of the rectangular lifting plate 12 close to the pulley seat 14. The first hand-tightening screw 16 penetrates the rectangular lifting plate 12 horizontally and extends into the center hole to press against the outer wall of the steel pipe 10.

[0039] Working Principle: In the cross-arm mechanism, a rectangular lifting plate 12 is mounted on the steel pipe 10 of the ground pile column mechanism and can move up and down along the steel pipe 10. The height of the cross-arm mechanism can be changed by adjusting its position. Two guide shafts 13 pass horizontally through both sides of the rectangular lifting plate 12, providing guidance and support for the pulley seat 14, which is used to mount the anti-skid sheave 5. The center hole of the rectangular lifting plate 12 allows the steel pipe 10 to pass through, and flange locating sleeves 15 at the upper and lower ends assist in its stable sliding. A first hand-tightening screw 16 is screwed onto the side of the rectangular lifting plate 12 near the pulley seat 14. When tightened, it fixes the rectangular lifting plate 12 to the steel pipe 10 to prevent it from moving.

[0040] Purpose and Effect: This cross-arm mechanism design precisely adjusts the height and position of the anti-slip groove wheel 5 to accommodate different sizes of protective nets 2 and different forest and grass cultivation scenarios. By adjusting the height of the rectangular lifting plate 12, the height of the protective net 2 can be changed to meet the protection needs of forest and grass at different heights.

[0041] The tightening mechanism includes a diamond-shaped end plate 17 fixedly connected to the other ends of the two guide shafts 13, a long screw 18 passing through the diamond-shaped end plate 17, and an adapter sleeve 19. A threaded through hole 20 for the long screw 18 to pass through is opened at the center of the diamond-shaped end plate 17. A flat portion 21 is formed on the outer wall of the end of the long screw 18 away from the rectangular lifting plate 12. The adapter sleeve 19 is sleeved on the end of the long screw 18 and fastened to the outside of the flat portion 21 by means of a top screw. A hexagonal wrench hole 22 is formed at the outer end of the adapter sleeve 19.

[0042] Working principle: The diamond-shaped end plate 17 of the tightening mechanism is connected to the other end of the two guide shafts 13. The long screw 18 passes through the threaded through-hole 20 of the diamond-shaped end plate 17. Axial movement can be achieved by rotating the long screw 18. The adapter sleeve 19 is sleeved on the end of the long screw 18 and fixed to the flat part 21 of the long screw 18 by a top screw. The hexagonal wrench hole 22 at the outer end of the adapter sleeve 19 facilitates the use of a wrench to rotate the long screw 18. When the long screw 18 is rotated, one end of the long screw 18 gradually presses against the side wall of the rectangular lifting plate 12, thereby causing the whole composed of the diamond-shaped end plate 17, the two guide shafts 13 and the pulley seat 14 to translate in the direction of the guide shaft 13 passing through the rectangular lifting plate 12. During this process, the pulley seat 14 gradually tightens the wire rope 6, thereby adjusting the tightness of the wire rope 6.

[0043] Purpose or Effect: The tightening mechanism conveniently and quickly adjusts the tension of the steel wire rope 6. During use, the steel wire rope 6 may become loose or too tight due to various factors. By rotating the long screw 18 to move the diamond-shaped end plate 17, the tension of the steel wire rope 6 can be precisely adjusted to ensure that it is always at the appropriate tension state, ensuring the smooth operation of the protective reel 2 and preventing problems with the tension of the steel wire rope 6 from affecting the normal use of the device and the protection of forests and grasses.

[0044] The electric drive mechanism includes a drive motor 23, a main drive wheel 24 arranged on the output shaft of the drive motor 23, a driven wheel 25 and a first synchronous belt 26 for connecting the main drive wheel 24 and the driven wheel 25. The other end of the two guide shafts 13 of the main drive assembly 3 is fixedly connected to a shaft seat 27. The driven wheel 25 is arranged in the shaft seat 27. A first synchronous wheel 28 is provided on both sides of the pulley seat 14. The two first synchronous wheels 28 and the anti-skid groove wheel 5 located therebetween are coaxially fixedly connected. A first synchronous wheel 28 is provided on both sides of the shaft seat 27. Two synchronous wheels 29, two second synchronous wheels 29 and the driven wheel 25 located therebetween are coaxially fixedly connected, each first synchronous wheel 28 and the corresponding second synchronous wheel 29 are connected by a second synchronous belt 30, a beam frame is provided between the main drive wheel 24 and the driven wheel 25, the beam frame consists of two beam plates 31 and a strip plate 32, the strip plate 32 is located on the inner side of the first synchronous belt 26, the two beam plates 31 are fixedly connected to both sides of the strip plate 32, and the two ends of each beam plate 31 are respectively connected to the main drive wheel 24 and the driven wheel 25.

[0045] Working Principle: In the electric drive mechanism, after the drive motor 23 is activated, it drives the main drive wheel 24 to rotate. The main drive wheel 24 transmits power to the driven wheel 25 via the first synchronous belt 26. The driven wheel 25 then transmits power to the first synchronous wheel 28 on the pulley seat 14 via the second synchronous belt 30, thereby driving the anti-skid groove pulley 5 to rotate. The shaft seat 27 is used to mount the driven wheel 25. The first synchronous wheel 28 on the pulley seat 14, the anti-skid groove pulley 5, and the second synchronous wheel 29 on the shaft seat 27 and the driven wheel 25 are all coaxially connected to ensure accurate power transmission. The beam frame, consisting of two beam plates 31 and a strip plate 32, supports and secures the first synchronous belt 26, ensuring its stability during transmission.

[0046] Purpose or Effect: The electric drive mechanism powers the anti-skid sheave 5, providing power for deploying and retracting the protective net 2. The synchronous belt drive ensures smooth and accurate power transmission, reducing energy loss and noise during the transmission process. The beam design enhances the stability of the synchronous belt drive system, preventing the belt from swerving or slipping during operation. This improves the operating efficiency and reliability of the device, enabling the protective net 2 to be deployed and retracted quickly and stably, meeting the protection requirements of forest and grass cultivation.

[0047] The two beam plates 31 are each formed with a straight edge portion 33 perpendicular to the beam plate 31 at one end close to the drive motor 23. The straight edges 33 of the two beam plates 31 are tightly connected. A waist hole 34 is provided at the connection between the beam plate 31 and the main drive wheel 24 for the sliding of the output shaft of the drive motor 23. The outer sides of the two beam plates 31 are each provided with a bearing sleeved on the output shaft of the drive motor 23. A U-shaped bracket 35 is also provided on the outer side of the two beam plates 31. The two ends of the U-shaped bracket 35 are respectively sleeved on the outer rings of the two bearings. A second hand-tightened screw 36 is screwed on the top of the U-shaped bracket 35, and the end of the second hand-tightened screw 36 is pressed against the intersection of the two straight edges 33.

[0048] Working Principle: Two beams 31 are securely connected near the straight edges 33 at one end of the drive motor 23, forming a stable structure. A waist hole 34 in the beam 31 provides sliding space for the output shaft of the drive motor 23, facilitating adjustment of the position of the main drive wheel 24 to ensure the tension of the first timing belt 26. A U-shaped bracket fits over the outer ring of the bearing. A second hand-tightened screw 36 presses against the intersection of the two straight edges 33, securing the U-shaped bracket in place. This, in turn, secures the bearing and the output shaft of the drive motor 23, preventing them from loosening during operation.

[0049] Purpose and Effect: This structural design facilitates adjustment of the tension of the first synchronous belt 26 and securement of the drive motor 23. During installation and use, by adjusting the position of the main drive wheel 24, the first synchronous belt 26 can maintain appropriate tension, ensuring stable power transmission. The U-shaped bracket and the second hand-tightening screw 36 enhance the securement of the drive motor 23, preventing it from loosening due to factors such as vibration during operation. This improves the reliability and stability of the electric drive mechanism and ensures the continuous and stable operation of the protective roll net 2.

[0050] The bottom of the driving motor 23 is fixedly connected to a flat base 37, and two spaced-apart raising seats 38 are provided at one end of the flat base 37 away from the driving motor 23. The top of each raising seat 38 is fixedly connected to a bearing seat 39 for connecting to the rotating support shaft 8, and a handle 40 is fixedly connected to the center of the flat base 37.

[0051] Working Principle: The flat base 37 at the bottom of the drive motor 23 provides support for it. The raised base 38 and bearing seat 39 are used to mount the rotating support shaft 8, ensuring stable rotation of the rotating support shaft 8. The handle 40 facilitates the transportation of the drive motor 23 and related components, providing convenience during installation, removal, or movement of the device.

[0052] Purpose and Effect: The design of the flat base 37, raised base 38, and bearing seat 39 ensures the stable installation and operation of the drive motor 23 and the rotating support shaft 8, providing reliable support for the rotation of the protective roll net 2. The provision of the handle 40 improves the portability of the device, facilitating installation and movement between different forest and grass cultivation areas, reducing labor intensity and improving work efficiency.

[0053] The driving motor 23 adopts a brake motor, and the end of the rotating support shaft 8 that is plugged into the central shaft tube 7 of the protective roll net 2 is provided with a corresponding pin hole 41. A locking shaft seat 42 is provided between the two bearing seats 39. The locking shaft seat 42 is provided with a through hole 43 with a diameter larger than the diameter of the rotating support shaft 8 and an elastic shrinkage gap 44 extending longitudinally and passing through the through hole 43. A bolt 45 for loosening and tightening the elastic shrinkage gap 44 is screwed onto the top of the locking shaft seat 42.

[0054] Working Principle: Drive motor 23 utilizes a brake motor, enabling rapid braking upon stopping, preventing the protective net 2 from further movement due to inertia. The rotating support shaft 8 is connected to the central shaft 7 of the protective net 2 by means of a pin hole 41. A perforation 43 in the locking shaft seat 42 allows the rotating support shaft 8 to pass through. An elastically contracted gap 44 and bolt 45 adjust the degree of grip on the rotating support shaft 8, thereby securing it in place and preventing rotation.

[0055] Purpose and Effect: The brake motor ensures the safety of the protective roll 2 when stopped, preventing inadvertent movement of the protective roll 2 due to inertia, which could damage the forest or cause equipment failure. The design of the pin hole 41 and the locking shaft seat 42 ensures the reliable connection and fixation of the rotating support shaft 8 to the central shaft 7 of the protective roll 2. When the protective roll 2 needs to be fixed in position, the elastic contraction gap 44 can be tightened by adjusting the bolt 45 to fix the rotating support shaft 8, ensuring that the protective roll 2 remains stable and meets the different protection requirements during forest and grass cultivation.

[0056] An oblique support arm 46 is provided between the upper half of the steel pipe 10 and the ground, and an anti-slip tooth plate 47 is hinged at the end of the oblique support arm 46 close to the ground, and an adjustable tensioning rod 48 is provided between the lower end of the oblique support arm 46 and the end of the steel pipe 10 close to the ground. One end of the oblique support arm 46 and the adjustable tensioning rod 48 are both axially connected to the steel pipe 10 through a first sliding sleeve 49, and the first sliding sleeve 49 is fixedly connected to the steel pipe 10 by means of a radial top screw. A fork 50 is provided at the bottom of the cross arm mechanism for driving the first sliding sleeve 49 below to rotate synchronously with it.

[0057] Working Principle: The upper half of the steel tube 10 is connected to the ground via an oblique support arm 46 and an adjustable tension rod 48. A hinged anti-slip tooth plate 47 is attached to one end of the oblique support arm 46, increasing friction with the ground and preventing the device from tilting. The oblique support arm 46 and the adjustable tension rod 48 are axially connected to the steel tube 10 via a first sliding sleeve 49. The first sliding sleeve 49 is secured with radial screws, allowing the installation position of the oblique support arm 46 and the adjustable tension rod 48 to be adjusted. A shift fork 50 at the bottom of the cross-arm mechanism rotates the first sliding sleeve 49 below, thereby adjusting the angle of the oblique support arm 46 and the adjustable tension rod 48 to suit different terrains and support requirements.

[0058] Purpose and Effect: This structure enhances the stability of the ground pile column mechanism, preventing it from tilting or collapsing during use. The inclined support arm 46 and anti-slip tooth plate 47 increase the contact area and friction between the device and the ground. The adjustable tension rod 48 can adjust the tension according to actual conditions to ensure the stability of the ground pile column mechanism. The design of the shift fork 50 enables flexible adjustment of the angle of the inclined support arm 46 and the adjustable tension rod 48. Under different terrain conditions, their angles can be adjusted to achieve the optimal support effect, improving the adaptability and stability of the device and ensuring the normal operation of the forest and grass cultivation device.

[0059] The adjustable tensioning rod 48 includes two symmetrically arranged threaded pull rods 51 and an internally threaded hexagonal prism 52 for screwing the opposite ends of the two threaded pull rods 51. The outer end of one threaded pull rod 51 is axially connected to the corresponding first sliding sleeve 49, and the outer end of the other threaded pull rod 51 is axially connected to a second sliding sleeve 53. The second sliding sleeve 53 is fixedly sleeved on the lower end of the oblique support arm 46.

[0060] Working Principle: The adjustable tension rod 48 consists of two threaded tie rods 51 and an internally threaded hexagonal prism 52. The two threaded tie rods 51 are axially connected to the first sliding sleeve 49 and the second sliding sleeve 53, respectively. By rotating the internally threaded hexagonal prism 52, the two threaded tie rods 51 can be moved toward or away from each other, thereby adjusting the length of the adjustable tension rod 48 and changing the tension between the diagonal support arm 46 and the steel pipe 10.

[0061] Purpose and Effect: The adjustable tension rod 48 conveniently adjusts the tension between the diagonal support arm 46 and the steel pipe 10. In different terrains and usage scenarios, the length of the adjustable tension rod 48 can be adjusted to meet actual needs, changing the support angle and tension of the diagonal support arm 46 to ensure the stability of the ground pile column mechanism. By precisely adjusting the tension, the device can better adapt to various environmental conditions, improve its reliability and service life, and provide more stable protection for forest and grass cultivation.
