Description

Technical Field

[0001] The invention relates to the technical field of soil and water conservation, and in particular to a meadow resurfacing device. Background Art

[0002] Alpine meadows are alpine or alpine herbaceous plants that grow at high altitudes and in cold climates. They play an important role in preventing soil erosion and maintaining the ecological environment in the Qinghai-Tibet Plateau. During the construction of production and construction projects, in order to avoid and reduce damage to local vegetation, herbaceous vegetation is often stripped before construction and stored in designated maintenance devices, and then replanted after the main project is completed. The in-situ meadow replanting method is not only economical and convenient, but also can effectively improve the survival rate of vegetation. Among them, how to simplify and optimize the meadow replanting device has always been the focus of research.

[0003] The Chinese patent with publication number CN211931765U discloses a turf re-laying and health-maintaining device for high-altitude and cold regions, including a turf re-laying and health-maintaining device, which is provided with a rotating rod, a mounting plate, a placement trough and a conveyor belt, etc. The device can effectively re-lay the meadow and spray nutrient solution, but the device has a complex body structure and is relatively bulky, and its use in field conditions is greatly limited; the Chinese patent with publication number CN109392617A discloses a turf transplanting device for landscaping, which discloses a transplanting device composed of a paving structure, a turf conveying structure, a paving drive, etc., which is efficient. The problem of evenly laying the turf on the ground is solved, but there is a lack of storage device for multiple pieces of turf, which needs to be loaded repeatedly and then laid flat, which is not conducive to the re-laying of large-scale meadows in high-altitude cold areas; Chinese patent publication number CN112449815A discloses a seaweed plant transplanting device and transplanting method, including a transplanting device with a seedling storage mechanism, a transplanting mechanism, a walking frame and a driving mechanism. The device realizes the mechanized transplanting of plants, and the row spacing, plant spacing and insertion depth of the plants are all adjustable and controllable. The driving mechanism of the device is a pneumatic mechanism with limited power storage, which is not suitable for long-term and large-area use.

[0004] In summary, the existing alpine meadow re-laying devices are extremely limited and relatively little research has been done. The mechanical devices for re-laying turf have the following main deficiencies: 1. Some devices have complex structures and are relatively bulky, making them difficult to transport and use in the field; 2. Some devices lack turf storage devices and require repeated loading and re-laying, which is not conducive to the re-laying of large areas of meadows in alpine areas, and manual operation is time-consuming and labor-intensive; 3. Some devices take into account the flatness, beauty and surface nutrient solution replenishment of the meadow during re-laying, but ignore the damage to the meadow root system after paving, resulting in a significantly reduced survival rate.

[0005] Therefore, how to change the current situation in the prior art where the meadow re-paving device has a complex structure and high laying cost has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0027] The purpose of the present invention is to provide a meadow re-paving device to solve the problems existing in the above-mentioned prior art, simplify the structure of the meadow re-paving device and reduce the laying cost.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figure 1-Figure 3 ,in, Figure 1 is a schematic structural diagram of a meadow resurfacing device according to the present invention, Figure 2 for Figure 1 An enlarged schematic diagram of the structure in the middle. Figure 3 It is a partial structural schematic diagram of the meadow repaving device of the present invention.

[0030] The present invention provides a meadow re-laying device, including a forklift unit and a meadow suspension storage unit, wherein the forklift unit includes a forklift body 1, a gantry 2 and a cargo fork 3, the gantry 2 is connected to the forklift body 1, the cargo fork 3 is slidably connected to the gantry 2, and the forklift body 1 can drive the gantry 2 and the cargo fork 3 to move; the meadow suspension storage unit includes a suspension component and a storage component, the suspension component includes a support frame 4, the support frame 4 is detachably connected to the gantry 2, the support frame 4 can be folded, and when the support frame 4 is unfolded, it can support the meadow block 17 to be laid, and the support frame 4 is two groups, the two groups of support frames 4 are symmetrically arranged with the center line of the door frame 2 as the axis, and the connecting line of the two groups of support frames 4 is perpendicular to the reciprocating sliding direction of the fork 3; the storage component includes a supporting plate 5, the supporting plate 5 is detachably connected to the support frame 4, the supporting plate 5 can accommodate humus 18 and meadow blocks 17 to be laid, and the supporting plate 5 is made of degradable material; the number of suspension components is multiple groups, and the multiple groups of suspension components are arranged along the height direction of the door frame 2; the storage components correspond one-to-one to the suspension components, or the storage components correspond one-to-one to the support frames 4.

[0031] The meadow re-laying device of the present invention, when working, places the support plate 5 provided with humus soil 18 on the fork 3 in the forklift unit, the fork 3 can fork the meadow block 17 out of the stacking area, so that the meadow block 17 is transferred to the support plate 5, the fork 3 slides upward relative to the door frame 2, so that the support plate 5 is connected to the topmost suspension assembly, and the suspension storage of the meadow block 17 is completed from top to bottom, until the last group of storage assemblies is connected to the suspension assembly, during the upward movement of the fork 3, the lower support frame 4 can be folded to prevent the support frame 4 from affecting the reciprocating sliding of the fork 3, each group of suspension assemblies includes two groups of support frames 4, which improves the support stability of the meadow block 17. When the meadow is re-laid, the forklift body 1 drives the fork 3, the door frame 2 and the meadow suspension storage unit to move to the meadow re-laying area, the fork 3 slides from bottom to top, starting from the bottommost meadow suspension storage unit, so that the storage assembly is separated from the suspension assembly, and the support plate 5 and the meadow block 17 are re-laid to the surface vegetation disturbance area. The meadow re-laying device of the present invention has a simple structure, is easy to operate, and saves manpower and material resources. The support frame 4 is detachably connected to the door frame 2. In practical applications, it can be implemented by modifying an existing forklift, which further simplifies the device structure and reduces the cost of meadow re-laying. In addition, the present invention sets humus 18 between the support plate 5 and the meadow block 17, and the support plate 5 is made of a degradable material, which ensures the normal growth of the meadow root system after paving and improves the survival rate of the meadow. In other specific embodiments of the present invention, each group of support frames 4 is used to hang a group of storage components to adapt to the smaller size of the meadow block 17 and improve the storage and transportation efficiency of the meadow block 17.

[0032] In this specific embodiment, the support frame 4 includes a crossbar 6 and a pull rod 7, one end of the crossbar 6 is hinged to the door frame 2, one end of the pull rod 7 is hinged to the door frame 2 and is located at the top of the crossbar 6, and the other end of the pull rod 7 can be connected to the crossbar 6 by a hinge buckle, and the hinge buckle is a split structure and can be separated, and the crossbar 6, the pull rod 7 and the door frame 2 can form a triangular structure. After the fork 3 removes the storage assembly and the meadow block 17 at the bottom, the fork 3 moves upward, pushes the crossbar 6, and separates the hinge buckle, thereby achieving the purpose of separating the crossbar 6 from the pull rod 7. Under the push of the fork 3, the crossbar 6 and the pull rod 7 rotate to avoid affecting the fork 3 from continuing to move upward. Repeat the above action until the fork 3 removes the storage assembly and the meadow block 17 at the top, the fork 3 slides downward, the crossbar 6 and the pull rod 7 rotate and reset, and the hinge buckle is connected at the same time, that is, the crossbar 6 and the pull rod 7 are reconnected, ready for subsequent meadow storage. It should be explained here that the hinged buckle can be a magnetic buckle, and the hinged buckle includes a block and a position, one of which is set on the cross bar 6, and the other is set on the pull rod 7. When the fork 3 pushes the support frame 4, the block and the position are separated, and the cross bar 6 is separated from the pull rod 7. During the resetting process of the cross bar 6 and the pull rod 7, the block and the position are reconnected to achieve the connection between the cross bar 6 and the pull rod 7. The use of a magnetic buckle can make the block and the position smoothly connected, reducing the difficulty of operation. In other specific embodiments of the present invention, the support frame 4 can select other foldable structures. Similarly, other types of buckles can also be selected. Selecting the buckle type according to the actual working conditions is a common practice of those skilled in the art and will not be repeated here. In addition, when the forklift unit is modified using a forklift in the prior art, the fork 3 is mostly installed on the fork frame, and the fork frame can reciprocate relative to the door frame 2. When installing the suspension assembly, attention should be paid to reasonably setting the position and spacing of the support frame 4 to avoid interference between the support frame 4 and the fork frame, while ensuring that the fork 3 can work normally.

[0033] Specifically, the meadow suspension storage unit also includes a hook 8 and a ring 9. The hook 8 is connected to the crossbar 6. The ring 9 is set on the supporting plate 5. The hook 8 and the ring 9 are detachably connected. There is a hook-shaped object under the hook 8 that can be inserted into the ring 9. When storing the meadow block 17, the fork 3 drives the storage component to rise to a certain extent, and the ring 9 is put on the hook of the hook 8 to complete the connection between the storage component and the support frame 4; when laying, the storage component is driven to rise, so that the ring 9 is separated from the hook 8, and the storage component and the support frame 4 are separated. In practical applications, an anti-slip coating can be set at the ring 9 and the hook of the hook 8 to increase friction, prevent the meadow block 17 from slipping due to vibration during the transfer process, and improve the working stability of the device.

[0034] Among them, the cross bar 6 has a mounting hole 10, and one end of the hook 8 is rotatably arranged in the mounting hole 10. The mounting hole 10 is provided to facilitate the installation and positioning of the hook 8. Each cross bar 6 is connected to two hooks 8, and the two hooks 8 are respectively located on both sides of the connection point between the cross bar 6 and the pull rod 7. The lifting ring 9 corresponds to the hook 8 one by one, and multi-point support is provided to improve the stability of the meadow block 17 during storage and transportation.

[0035] More specifically, the storage assembly further comprises a buffer membrane 11, which can be covered on the meadow block 17 to be laid. The buffer membrane 11 is water-permeable and air-permeable, and can effectively prevent water and soil erosion.

[0036] In this specific embodiment, the support plate 5 is made of degradable geotextile, which is cheap, easy to make, and can adapt to meadow blocks 17 of various specifications. In practical applications, the support plate 5 can also be made of other degradable materials to avoid environmental pollution.

[0037] Furthermore, the meadow re-laying device further includes a spraying and raising unit, which includes a water tank 12 and a shower 13. The water tank 12 is arranged on the forklift body 1, and the shower 13 is connected to the water tank 12. The shower 13 can spray the laid meadow block 17. Water or nutrient solution can be placed in the water tank 12. After the meadow is re-laid, the meadow is evenly irrigated by the shower 13 to further improve the survival rate of the meadow. The present invention provides a buffer film 11 on the meadow block 17, which can reduce the scouring of the surface of the meadow block 17 by spraying, and effectively protect the meadow block 17. In this specific embodiment, the water tank 12 is fixed to the top of the forklift body 1, so that the water or nutrient solution in the water tank 12 can be smoothly output under the action of gravity.

[0038] In order to improve the flexibility of irrigation, the spraying and raising unit also includes a connecting hose 14 and a control valve 15. The shower head 13 is connected to the water tank 12 via the connecting hose 14, which facilitates the adjustment of the direction of the shower head 13. The control valve 15 is arranged between the water tank 12 and the connecting hose 14 to further improve the controllability of the irrigation.

[0039] At the same time, a filter screen 16 is provided at the connection point between the water storage tank 12 and the connecting hose 14. The filter screen 16 can filter solid impurities in water or nutrient solution to prevent the shower head 13 from being blocked, thereby improving the working reliability of the spraying and breeding unit.

[0040] Furthermore, multiple groups of suspension components are arranged at equal intervals along the height direction of the gantry 2, which improves the control of the fork 3 and the convenience of laying the meadow. It should also be noted that in this specific embodiment, the forklift body 1 uses a hydraulic system and a lifting chain to drive the fork 3 to reciprocate. In actual application, the operator can also select a suitable power and transmission structure according to specific working conditions.

[0041] The meadow re-laying device of the present invention fills humus 18 in a support plate 5 made of a degradable geotextile, and then places the support plate 5 on the fork 3, and uses the fork 3 to fork the meadow block 17 from the temporary storage area. The fork 3 is raised, and from the top to the bottom of the door frame 2, the ring 9 connected to the support plate 5 is hung on the hook 8 of the support frame 4 in sequence to complete the storage of the meadow block 17. The forklift unit transports the meadow block 17 to the surface vegetation disturbance area, and the fork 3 takes out the meadow block 17 and the support plate 5 in order from the bottom to the top of the door frame 2, and re-lays them to the surface disturbance area, opens the control valve 15, and uses the sprinkler 13 to maintain the re-laid meadow block 17.

[0042] Using the meadow re-paving device of the present invention, a 5-kilometer test section was selected in the Qinghai-Tibet GL oil pipeline project to replant the damaged vegetation surface. A total of one device was assembled in this test, and two workers re-paved 1,832 meadows after working for three days (8 hours a day), and the re-paving efficiency was 305 pieces / person / day. According to the workload information data of traditional manual replanting, six workers re-paved 1,113 meadows after working for three days (8 hours a day), and the re-paving efficiency was about 62 pieces / person / day. By comparison, it can be seen that the work efficiency of meadow re-paving using the meadow re-paving device of the present invention is about 5 times that of traditional manual re-paving, and when completing the same workload, the labor cost required by the present invention is only 1 / 3 of the traditional manual re-paving cost, which has the advantages of high meadow re-paving efficiency and low cost. After the meadow was re-paved, the survival and growth of the re-paved meadow were monitored and analyzed monthly in the following year. The results showed that the survival rate of meadow block 17 was 82.7% one month after transplantation, which was much higher than the 40% survival rate of the re-paved meadow in the existing engineering application device. A continuous grass bed was gradually formed after 7 to 8 months, and the area reached its maximum value after 11 months. The marginal plants grew well.

[0043] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
