Description

Technical Field

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

[0002] In the current process of ecological environment construction and urban greening development, forest and grass cultivation, as a key link, undertakes the important mission of maintaining ecological balance and beautifying the environment. Whether it is urban parks, green belts along roadsides, or large-scale nursery bases, the cultivation and maintenance of forest and grass vegetation have received extensive attention. With the continuous improvement of people's requirements for the quality of the ecological environment, the scale and refinement level of forest and grass cultivation are also continuously increasing. Traditional manual cultivation and simple protection methods are no longer able to meet the efficient, scientific, and precise requirements of modern forest and grass cultivation. However, in the actual process of forest and grass cultivation, especially in lawn and nursery areas, there are many technical problems to be solved. 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 at will, and nursery bases may also cause mechanical damage to forest and grass during daily management and transportation, resulting in damaged growth of forest and grass and an extended recovery period. On the other hand, existing protection measures, such as fixed fences or simple covering nets, either have poor flexibility and cannot be adjusted according to different stages and requirements of forest and grass cultivation, or have limited protection effects and are difficult to effectively resist external interference. Moreover, when forest and grass need growth conditions such as light and ventilation, the protection cannot be removed in time, affecting the normal growth of forest and grass. 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 forest and grass.

[0014] The beneficial effects of the present invention compared with the prior art are as follows: First, the protection is flexible and adjustable: Existing protection measures such as fixed fences or simple covering nets have poor flexibility and are difficult to adjust according to different stages and requirements of forest and grass cultivation. In this solution, the forest and grass cultivation device with a protection function can conveniently deploy and retract the protective rolling net through two sets of large-span traction components and the retractable protective rolling net. When the forest and grass need protection, the protective rolling net is deployed to resist external interference; when the forest and grass need growth conditions such as light and ventilation, the protective rolling net can be retracted in time to meet the normal growth needs of the forest and grass, and the protection state can be flexibly adjusted; Second, it can effectively resist external interference: In the current forest and grass cultivation, the lawn and nursery areas are often disturbed by human or animal activities, and the existing protection measures have limited protection effects. In this solution, the two outermost ends of the protective rolling net are fixedly connected to the steel wires on both sides, and the tightening mechanism of the auxiliary support component can drive the anti-slip grooved wheel to tighten the steel wire in the reverse direction, ensuring that the steel wire is in an appropriate tension, making the protective rolling net stable, and being able to more effectively resist external interference, reducing the growth damage of forest and grass caused by external interference and shortening the recovery period; Third, it can adapt to different terrains and requirements: Traditional forest and grass cultivation methods and protection measures are difficult to adapt to diverse terrains and the refined requirements of forest and grass cultivation. In this solution, the steel pipe of the ground pile column mechanism can be movably inserted into the cylindrical bottom pile and fixed by a flange-shaped limiting sleeve and a radial set screw, and the height can be flexibly adjusted to adapt to different terrains; the rectangular lifting plate of the cross-arm mechanism can move up and down along the steel pipe and is fixed by a first hand-tightening screw rod, and the height and position of the anti-slip grooved wheel can be accurately adjusted to meet the requirements of different specifications of protective rolling nets and forest and grass cultivation, improving the adaptability and practicability of the device.

Detailed implementation manners

[0016] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0017] Refer to Figures 1 to 10As 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 both ends of the length or width direction of the nursery, 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 tube 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.

[0018] Working principle: The core of the forest and grass cultivation device is composed of two groups of large-span traction components 1 and protective roll nets 2. The large-span traction components 1 are distributed along the length or width of the nursery, and each group has a main drive component 3 and a secondary support component 4 located at both ends. In the main drive component 3 and the secondary support component 4, the ground pile column mechanism is rooted in the ground to provide stable support; the cross arm mechanism is installed above it and can be flexibly adjusted; the anti-skid groove wheel 5 is installed at one end of the cross arm mechanism. The anti-skid groove wheels 5 of the two groups of components are connected by a closed steel wire rope 6 to form a transmission system. After the electric drive mechanism of the main drive component 3 is started, it drives the anti-skid groove wheel 5 to rotate, thereby pulling the steel wire rope 6 to move; the tightening mechanism of the secondary support component 4 can adjust the tightness of the steel wire rope 6 to ensure that it is at a suitable tension. The two ends of the protective roll net 2 are fixed on the steel wire rope 6. As the steel wire rope 6 moves, the protective roll net 2 can be unfolded or retracted to achieve coverage or exposure of the forest and grass.

[0019] Purpose and effect: This design realizes flexible protection of forest and grass cultivation areas. The electric drive mechanism drives the steel wire rope 6 to drive the protective reel 2, which can conveniently control the protection range. When it is necessary to protect the forest and grass, the protective reel 2 can be unfolded to resist adverse external factors such as animal damage and bad weather; when it is not needed, it can be folded up to facilitate daily management and growth observation of the forest and grass. The tightening mechanism ensures that the steel wire rope 6 is always in the appropriate tension, avoiding unstable operation of the protective reel 2 due to the steel wire rope 6 being too loose, or damaging equipment components due to being too tight, thereby improving the reliability and stability of the device.

[0020] The ground pile column mechanism includes a cylindrical bottom pile 9 embedded under the ground surface, a steel pipe 10 movably inserted in 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.

[0021] Working principle: The cylindrical bottom pile 9 of the ground pile column mechanism is pre-buried below the ground surface to provide basic support for the entire device. The steel pipe 10 can be movably inserted into the cylindrical bottom pile 9 and its height can be adjusted according to actual needs. The flange-shaped limiting sleeve 11 is sleeved outside the steel pipe 10 and fixed by a radial set screw to prevent the steel pipe 10 from moving up and down. The stepped sinking groove at the top of the cylindrical bottom pile 9 can accommodate the flange-shaped limiting sleeve 11, making the installation of the limiting sleeve more stable and playing a positioning role for the steel pipe 10 at the same time.

[0022] Purpose and effect: This structural design enables the height of the ground pile column mechanism to be flexibly adjusted to adapt to different terrains 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 that the cross-arm mechanism and the anti-slip groove wheel 5 are in appropriate positions to ensure the normal operation of the entire device. The cooperation between the flange-shaped limiting sleeve 11 and the stepped sinking groove enhances the stability and reliability of the ground pile column mechanism, prevents the steel pipe 10 from loosening during use, and improves the overall safety of the device.

[0023] The cross-arm mechanism includes a rectangular lifting plate 12 that is horizontally movably sleeved on the upper end of the ground pile column mechanism, two guide shafts 13 that horizontally movably penetrate both sides of the rectangular lifting plate 12, 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 axially connecting and installing the corresponding anti-slip groove wheel 5. The length of the guide shaft 13 is greater than the length of the side of the rectangular lifting plate 12 that is penetrated. A central hole for the steel pipe 10 to pass through is formed at the center of the rectangular lifting plate 12. Flange positioning sleeves 15 that are coaxial with the central hole are fixedly connected to both the upper and lower ends of the rectangular lifting plate 12. The flange positioning sleeves 15 are slidably sleeved on the outside of the steel pipe 10. A first hand-tightening screw 16 is screwed on one side of the rectangular lifting plate 12 close to the pulley seat 14. The first hand-tightening screw 16 horizontally penetrates the rectangular lifting plate 12 and extends into the central hole to abut against the outer wall of the steel pipe 10.

[0024] Working principle: In the cross-arm mechanism, the rectangular lifting plate 12 is sleeved on the steel pipe 10 of the ground pile column mechanism and can move up and down along the steel pipe 10. By adjusting its position, the height of the cross-arm mechanism can be changed. The two guide shafts 13 horizontally pass through both sides of the rectangular lifting plate 12 to provide guidance and support for the pulley seat 14. The pulley seat 14 is used for installing the anti-slip groove wheel 5. The central hole of the rectangular lifting plate 12 allows the steel pipe 10 to pass through, and the flange positioning sleeves 15 at the upper and lower ends assist it to slide stably. The first hand-tightening screw 16 is screwed on one side of the rectangular lifting plate 12 close to the pulley seat 14. When tightened, it can fix the rectangular lifting plate 12 on the steel pipe 10 to prevent it from moving.

[0025] Purpose and effect: This cross-arm mechanism design can precisely adjust the height and position of the anti-slip grooved wheel 5 to adapt to protection net rolls 2 of different specifications and forest and grass cultivation scenarios. By adjusting the height of the rectangular lifting plate 12, the height at which the protection net roll 2 unfolds can be changed to meet the protection requirements of forests and grasses of different heights.

[0026] The tightening mechanism includes a rhombic end plate 17 fixedly connecting the other ends of two guide shafts 13, a long screw 18 passing through the rhombic end plate 17, and a transfer sleeve 19. A threaded through hole 20 for the long screw 18 to pass through is provided at the center of the rhombic 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 transfer sleeve 19 is sleeved on the end of the long screw 18 and is fastened to the outside of the flat portion 21 by a set screw. A hexagonal wrench hole 22 is formed at the outer end of the transfer sleeve 19.

[0027] Working principle: The rhombic end plate 17 of the tightening mechanism connects the other ends of the two guide shafts 13. The long screw 18 passes through the threaded through hole 20 of the rhombic end plate 17, and axial movement can be achieved by rotating the long screw 18. The transfer sleeve 19 is sleeved on the end of the long screw 18 and is fixed to the flat portion 21 of the long screw 18 by a set screw. The hexagonal wrench hole 22 at the outer end of the transfer 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 abuts against the side wall of the rectangular lifting plate 12, so that the whole formed by the rhombic end plate 17, the two guide shafts 13 and the pulley seat 14 translates. The translation direction is the direction in which the guide shaft 13 passes through the rectangular lifting plate 12. During this process, the pulley seat 14 gradually tightens the steel wire rope 6, thereby adjusting the tightness of the steel wire rope 6.

[0028] Purpose or effect: The tightening mechanism realizes the adjustment of the tension of the steel wire rope 6 conveniently and quickly. During the use of the device, the steel wire rope 6 may become loose or too tight due to various factors. By rotating the long screw 18 to drive the movement of the rhombic end plate 17, the tightness of the steel wire rope 6 can be precisely adjusted to ensure that it is always in an appropriate tension state, ensuring the stable operation of the protection net roll 2 and avoiding affecting the normal use of the device and the protection effect of forests and grasses due to the tension problem of the steel wire rope 6.

[0029] 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 ends of the two guide shafts 13 of the main drive assembly 3 are fixedly connected with a shaft seat 27. The driven wheel 25 is arranged inside the shaft seat 27. A first synchronous pulley 28 is respectively arranged on both sides of the pulley seat 14. The two first synchronous pulleys 28 and the anti-slip grooved pulley 5 located between them are coaxially fixedly connected. A second synchronous pulley 29 is respectively arranged on both sides of the shaft seat 27. The two second synchronous pulleys 29 and the driven wheel 25 located between them are coaxially fixedly connected. Each first synchronous pulley 28 and the corresponding second synchronous pulley 29 are connected by a second synchronous belt 30. A beam frame is arranged between the main drive wheel 24 and the driven wheel 25. The beam frame is composed of two beam plates 31 and a strip plate 32. The strip plate 32 is located inside the first synchronous belt 26. The two beam plates 31 are fixedly connected to both sides of the strip plate 32. Both ends of each beam plate 31 are respectively pivotally connected to the main drive wheel 24 and the driven wheel 25.

[0030] Working principle: In the electric drive mechanism, after the drive motor 23 is started, it drives the main drive wheel 24 to rotate. The main drive wheel 24 transmits power to the driven wheel 25 through the first synchronous belt 26. The driven wheel 25 then transmits power to the first synchronous pulley 28 on the pulley seat 14 through the second synchronous belt 30, thereby driving the anti-slip grooved pulley 5 to rotate. The shaft seat 27 is used to install the driven wheel 25. The first synchronous pulley 28, the anti-slip grooved pulley 5 on the pulley seat 14, the second synchronous pulley 29 on the shaft seat 27, and the driven wheel 25 are all coaxially fixedly connected to ensure the accuracy of power transmission. The beam frame is composed of two beam plates 31 and a strip plate 32, which plays a role in supporting and fixing the first synchronous belt 26 to ensure that the synchronous belt remains stable during the transmission process.

[0031] Purpose or effect: The electric drive mechanism realizes the power drive of the anti-slip grooved pulley 5, providing power for the deployment and retraction of the protective net 2. Through synchronous belt transmission, the smoothness and accuracy of power transmission are ensured, reducing energy loss and noise during the transmission process. The design of the beam frame enhances the stability of the synchronous belt transmission system, preventing problems such as deviation and slipping of the synchronous belt during operation, improving the operation efficiency and reliability of the device, enabling the protective net 2 to be deployed and retracted quickly and stably, and meeting the protection requirements during the forest and grass cultivation process.

[0032] At one end of each of the two beam plates 31 close to the driving motor 23, a straight edge portion 33 perpendicular to the beam plate 31 is formed. The straight edge portions 33 of the two beam plates 31 are firmly connected. At the connection between the beam plate 31 and the main driving wheel 24, a waist-shaped hole 34 is provided for the output shaft of the driving motor 23 to slide through. On the outer sides of the two beam plates 31, bearings sleeved on the output shaft of the driving motor 23 are provided. On the outer sides of the two beam plates 31, a U-shaped bracket 35 is further provided. The two ends of the U-shaped bracket 35 are respectively sleeved on the outer rings of the two bearings. At the top of the U-shaped bracket 35, a second hand-tightening screw 36 is screwed. The end of the second hand-tightening screw 36 abuts against the junction of the two straight edge portions 33.

[0033] Working principle: The straight edge portions 33 at one end of the two beam plates 31 close to the driving motor 23 are firmly connected to form a stable structure. The waist-shaped hole 34 on the beam plate 31 provides a sliding space for the output shaft of the driving motor 23, facilitating the adjustment of the position of the main driving wheel 24 to ensure the tension of the first synchronous belt 26. The U-shaped bracket is sleeved on the outer ring of the bearing. By tightening the junction of the two straight edge portions 33 with the second hand-tightening screw 36, the position of the U-shaped bracket can be fixed, thereby fixing the bearing and the output shaft of the driving motor 23 to prevent them from loosening during operation.

[0034] Purpose and effect: This structural design facilitates the adjustment of the tension of the first synchronous belt 26 and the fixation of the driving motor 23. During the installation and use of the device, by adjusting the position of the main driving wheel 24, the first synchronous belt 26 can be maintained at an appropriate tension to ensure the stability of power transmission. The cooperation of the U-shaped bracket and the second hand-tightening screw 36 enhances the fixing effect of the driving motor 23, preventing it from loosening due to vibration and other factors during operation, improving the reliability and stability of the electric drive mechanism, and ensuring the continuous and stable operation of the protective rolling net 2.

[0035] A flat base 37 is fixedly connected to the bottom of the driving motor 23. At one end of the flat base 37 away from the driving motor 23, two spaced-apart heightening seats 38 are provided. At the top of each heightening seat 38, a bearing seat 39 for connecting the rotating support shaft 8 is fixedly connected. A handle 40 is fixedly connected to the center of the flat base 37.

[0036] Working principle: The flat base 37 at the bottom of the driving motor 23 provides support for it. The heightening seats 38 and the bearing seats 39 are used to install the rotating support shaft 8, enabling the rotating support shaft 8 to rotate stably. The handle 40 facilitates the handling of the driving motor 23 and related components, providing convenience during the installation, disassembly, or movement of the device.

[0037] Purpose and effect: The designs of the flat base 37, the heightening seat 38, and the bearing seat 39 ensure the stable installation and operation of the driving motor 23 and the rotating support shaft 8, providing reliable support for the rotation of the protective net 2. The provision of the handle 40 improves the portability of the device, facilitating the installation and movement of the device by the staff in different forest and grass cultivation areas, reducing the labor intensity, and improving the work efficiency.

[0038] The driving motor 23 is a brake motor. At one end where the rotating support shaft 8 is inserted into the central shaft cylinder 7 of the protective net 2, corresponding pin holes 41 are provided. Between the two bearing seats 39, a locking shaft seat 42 is provided. A perforation 43 with a diameter larger than the diameter of the rotating support shaft 8 and an elastic contraction gap 44 extending longitudinally and passing through the perforation 43 are provided on the locking shaft seat 42. Above the locking shaft seat 42, a bolt 45 for tightening and loosening the elastic contraction gap 44 is rotatably provided.

[0039] Working principle: The driving motor 23 is a brake motor, which can be quickly braked when it stops running, preventing the protective net 2 from continuing to move due to inertia. The rotating support shaft 8 and the central shaft cylinder 7 of the protective net 2 are connected by inserting through the pin holes 41. The perforation 43 on the locking shaft seat 42 allows the rotating support shaft 8 to pass through. The elastic contraction gap 44 and the bolt 45 can adjust the clamping degree of the rotating support shaft 8, thereby fixing the position of the rotating support shaft 8 and preventing it from rotating.

[0040] Purpose and effect: The brake motor ensures the safety of the protective net 2 when it stops, avoiding accidental movement of the protective net 2 caused by inertia, resulting in damage to forest and grass or device failure. The designs of the pin holes 41 and the locking shaft seat 42 achieve the reliable connection and fixation of the rotating support shaft 8 and the central shaft cylinder 7 of the protective net 2. When it is necessary to fix the position of the protective net 2, the elastic contraction gap 44 can be tightened by adjusting the bolt 45 to fix the rotating support shaft 8, ensuring that the protective net 2 is in a stable state and meeting different protection requirements during the forest and grass cultivation process.

[0041] Between the upper half of the steel pipe 10 and the ground, an inclined support arm 46 is provided. At one end of the inclined support arm 46 close to the ground, an anti-slip tooth plate 47 is hinged. Between the lower end of the inclined support arm 46 and the end of the steel pipe 10 close to the ground, an adjustable tension rod 48 is provided. One ends of the inclined support arm 46 and the adjustable tension rod 48 are both axially connected to the steel pipe 10 through a first sliding sleeve 49. The first sliding sleeve 49 is fixedly connected to the steel pipe 10 by means of a radial set screw. At the bottom of the cross-arm mechanism, a fork 50 for driving the lower first sliding sleeve 49 to rotate synchronously with it is provided.

[0042] Working principle: The upper half of the steel pipe 10 is connected to the ground through the inclined support arm 46 and the adjustable tension rod 48. One end of the inclined support arm 46 is hinged with an anti-slip tooth plate 47, which can increase the friction with the ground and prevent the device from tilting. The inclined support arm 46 and the adjustable tension rod 48 are axially connected to the steel pipe 10 through the first sliding sleeve 49. The first sliding sleeve 49 is fixed by a radial set screw, and the installation positions of the inclined support arm 46 and the adjustable tension rod 48 can be adjusted. The fork 50 at the bottom of the cross-arm mechanism can drive the first sliding sleeve 49 below to rotate, thereby adjusting the angles of the inclined support arm 46 and the adjustable tension rod 48 to adapt to different terrains and support requirements.

[0043] Purpose and effect: This structure enhances the stability of the ground pile column mechanism and prevents it from tilting or collapsing during use. The inclined support arm 46 and the 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 the actual situation to ensure the stability of the ground pile column mechanism. The design of the fork 50 realizes the flexible adjustment of the angles of the inclined support arm 46 and the adjustable tension rod 48. Under different terrain conditions, the angles can be adjusted to achieve the best support effect, improving the adaptability and stability of the device and ensuring the normal operation of the forest and grass cultivation device.

[0044] The adjustable tension rod 48 includes two symmetrically arranged threaded tie rods 51 and an internal-threaded hexagonal prism 52 for screwing the opposite ends of the two threaded tie rods 51. The outer end of one threaded tie rod 51 is axially connected to the corresponding first sliding sleeve 49 respectively, and the outer end of the other threaded tie 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 inclined support arm 46.

[0045] Working principle: The adjustable tension rod 48 is composed of two threaded tie rods 51 and an internal-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 internal-threaded hexagonal prism 52, the two threaded tie rods 51 can move towards or away from each other, thereby adjusting the length of the adjustable tension rod 48 and changing the tension between the inclined support arm 46 and the steel pipe 10.

[0046] Purpose and effect: The adjustable tension rod 48 conveniently realizes the adjustment of the tension between the inclined support arm 46 and the steel pipe 10. Under different terrains and usage scenarios, the length of the adjustable tension rod 48 can be adjusted according to actual needs, changing the support angle and tension magnitude of the inclined 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 the reliability and service life of the device, and provide more stable protection for forest and grass cultivation.
