Description

Technical Field

[0001] This invention belongs to the field of spray equipment technology, specifically relating to a spray equipment and processing system for vegetation restoration in mining areas. Background Technology

[0002] Vegetation restoration is a crucial component of ecological restoration projects in mining areas, particularly on slopes prone to landslides, collapses, and debris flows. Restoring vegetation not only repairs the ecosystem but also helps stabilize the soil through plant roots, reducing the probability of these events. After planting, regular watering is essential to ensure healthy growth. For slopes, a common method is to install multiple irrigation nozzles at intervals along the slope from top to bottom. However, this method has drawbacks. Since multiple nozzles typically share a single water source, and the different nozzle locations and pipe lengths result in varying water flow times, controlling the water volume across all nozzles becomes difficult. This can lead to over-irrigation at some nozzles and under-irrigation at others. Summary of the Invention

[0003] The purpose of this invention is to provide a sprinkler system for vegetation restoration in mining areas, which can improve the uniformity of irrigation for plants.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this invention is as follows: This application provides a sprinkler system for vegetation restoration in mining areas, applied to mining slopes, comprising a water supply component and a sprinkler component. The water supply component includes a water collection channel and a water storage chamber. The water collection channel is arranged along the slope, and a recessed water collection chamber is provided on the bottom wall of the water collection channel. Multiple recessed water collection chambers are spaced apart along the extension direction of the water collection channel, and the water storage chamber communicates with the multiple recessed water collection chambers. The sprinkler component includes multiple sprinkler channels, which are spaced apart along the slope, and one of the sprinkler channels communicates with a recessed water collection chamber.

[0005] In some embodiments, along the extension direction of the water collection channel, the recessed water collection cavity includes a high side and a low side, and a filter screen is provided on the high side.

[0006] In some embodiments, the water supply assembly further includes a filter element comprising a rotating disk and four blades. The rotating disk is rotatably connected to the bottom wall of the water collection channel. The filter screen is arc-shaped and arranged around the bottom circumference of the rotating disk. The rotating disk is divided into a first region and a second region by a reference plane passing through the rotation center of the rotating disk and parallel to the extension direction of the water collection channel. One side of the filter screen is located at the top of the first region, and the other side is located at the bottom of the second region. The side wall of the water collection channel facing the second region is provided with a discharge channel. The bottom wall of the receiving plate is located at the bottom of the second region, and the bottom wall of the discharge channel is provided with a receiving plate that extends into the interior of the water collection channel.

[0007] The blades are movably connected to the rotating disk radially. The four blades are spaced apart around the rotation axis of the rotating disk. The four blades are configured such that when one of the blades is screwed into the bottom of the first region, the blade in the first region moves away from the axis of the rotating disk, while the other three blades move closer to the axis of the rotating disk.

[0008] In some embodiments, the rotating disk is provided with a mounting ring, and around the circumference of the mounting ring, a plurality of insertion holes are provided at intervals, into which blades are inserted.

[0009] In some embodiments, the bottom wall of the water collection channel is provided with an abutment portion, the abutment portion including an arc surface, and when the blade is configured to be screwed into the bottom of the first region, the end of the blade near the axis of the rotating disk abuts against the arc surface.

[0010] In some embodiments, the filter element further includes a protective sleeve and four limiting portions. The protective sleeve is disposed around the outer periphery of the four blades, and a first elastic element is disposed between the blades and the rotating disk. The four limiting portions are movably connected to the rotating disk radially, and are circumferentially spaced around the rotating disk. The limiting portions are disposed between two adjacent blades, and a second elastic element is disposed between the limiting portions and the rotating disk.

[0011] In some embodiments, the first elastic element includes a sleeve and an inner rod. The sleeve is connected to the blade. The inner rod is inserted into the sleeve and connected to the rotating disk, and a spring is disposed between the inner rod and the sleeve.

[0012] In some embodiments, the rotating disk is provided with a groove that extends radially along the rotating disk, and a limiting portion is slidably connected to the groove.

[0013] In some embodiments, a friction layer is provided on the inner wall of the end of the chute away from the axis of the rotating disk.

[0014] In some embodiments, the limiting portion is connected to a covering portion, which covers the opening of the groove.

[0015] The present invention has the following beneficial effects:

[0016] 1. Multiple recessed water collection chambers are equivalent to multiple water sources. By connecting the sprinkler channels to suitable recessed water collection chambers, the distance between multiple sprinkler channels and water sources can be made approximately the same. In this way, the time interval between water output when the sprinkler channels spray can be ignored, increasing the working synchronization rate of all sprinkler channels and thus improving the uniformity of irrigation for vegetation.

[0017] 2. The collection channel can be used to collect rainwater and can also be connected to the intercepting channel on the slope, so that the water in the intercepting channel can be discharged into the collection channel, thus improving the utilization rate of water resources.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0024] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0025] This application provides a sprinkler system for vegetation restoration in a mining area, applied to a slope 1, comprising a water supply component and a sprinkler component 2. The water supply component includes a water collection channel 5 and a water storage chamber 7. The water collection channel 5 is arranged along the slope 1, and a recessed water collection chamber 6 is provided on the bottom wall of the water collection channel 5. Multiple recessed water collection chambers 6 are spaced apart along the extension direction of the water collection channel 5, and the water storage chamber 7 communicates with the multiple recessed water collection chambers 6. The sprinkler component 2 includes multiple sprinkler channels 3, which are spaced apart along the slope 1, and one of the sprinkler channels 3 communicates with a recessed water collection chamber 6.

[0026] The collection channel 5 can be used to collect rainwater and can also be connected to the interception channel of the slope 1, so that the water in the interception channel can be discharged into the collection channel 5, thereby improving the utilization rate of water resources.

[0027] The recessed water collection cavity 6 is used to collect part of the water flowing into the water collection channel 5. Since multiple recessed water collection cavities 6 are arranged at intervals along the extension direction of the water collection channel 5, the elevation of each recessed water collection cavity 6 gradually increases from bottom to top. This allows the water to gradually fill each recessed water collection cavity 6 from top to bottom when it flows down the water collection channel 5.

[0028] The water storage chamber 7 is used to store water. During irrigation, when the water level in the recessed water collection chamber 6 is too low, the water stored in the water storage chamber 7 can be introduced into the recessed water collection chamber 6 by a water pump.

[0029] The sprinkler assembly 2 is used for spraying and irrigating plants.

[0030] For example, along the bottom of slope 1, multiple sprinkler channels 3 can be set at intervals, and multiple sprinkler channels 3 can spray different areas, thus improving the uniformity of irrigation.

[0031] The axial direction of the sprinkler channel 3 can extend along the width direction of the slope 1. Along the axial direction of the sprinkler channel 3, multiple sprinkler heads can be arranged at intervals, and water is supplied to the sprinkler heads through the sprinkler channel 3. The sprinkler heads can be of the type that can rotate automatically, and their structure and working principle are well known to those skilled in the art, and will not be described in detail here.

[0032] Each spray channel 3 may be equipped with a water pump to draw water from the recessed water collection chamber 6 into the spray channel 3.

[0033] The sprinkler channel 3 can be connected to the nearest recessed water collection chamber 6. The advantage of this setting is that multiple recessed water collection chambers 6 are equivalent to multiple water sources. By connecting the sprinkler channel 3 to the appropriate recessed water collection chamber 6, the distance between multiple sprinkler channels 3 and the water source can be made to be close to the same. In this way, the time interval between water output when the sprinkler channel 3 sprays can be ignored, which increases the working synchronization rate of all sprinkler channels 3 and thus improves the uniformity of irrigation for vegetation.

[0034] The water storage chamber 7 is used to replenish water to the corresponding concave water collection chamber 6 when the water level in the concave water collection chamber 6 is too low.

[0035] A water pump can be installed between the recessed water collection chamber 6 and the water storage chamber 7 so that water in the water storage chamber 7 can be sent into the recessed water collection chamber 6.

[0036] In some embodiments, along the extending direction of the water collection channel 5, the recessed water collection cavity 6 includes a high side and a low side, and a filter screen 11 is provided on the high side.

[0037] The filter screen 11 is used to filter the water flow in the water collection channel 5, reducing the risk of impurities such as rocks or leaves discharged from upstream falling into the recessed water collection cavity 6.

[0038] In some embodiments, the water supply assembly further includes a filter element 8, which includes a rotating disk 12 and four blades 15. The rotating disk 12 is rotatably connected to the bottom wall of the water collection channel 5, and the rotation axis of the rotating disk 12 is perpendicular to the bottom wall of the water collection channel 5. The filter screen 11 is arc-shaped and is arranged around the bottom circumference of the rotating disk 12. The rotating disk 12 is divided into a first region 25 and a second region 24 by a reference plane. The reference plane passes through the rotation center of the rotating disk 12 and is parallel to the extension direction of the water collection channel 5. One side of the filter screen 11 is located at the top of the first region 25, and the other side is located at the bottom of the second region 24. The side wall of the water collection channel 5 facing the second region 24 is provided with a discharge channel 9. The bottom wall of the receiving plate 10 is located at the bottom of the second region 24, and the bottom wall of the discharge channel 9 is provided with the receiving plate 10. The receiving plate 10 extends into the interior of the water collection channel 5.

[0039] The blade 15 is movably connected to the rotating disk 12 along the radial direction of the rotating disk 12. The four blades 15 are spaced apart around the rotation axis of the rotating disk 12. The four blades 15 are configured such that when one of the blades 15 is screwed into the bottom of the first region 25, the blade 15 located in the first region 25 moves away from the axis of the rotating disk 12, while the other three blades 15 move closer to the axis of the rotating disk 12.

[0040] The rotating disk 12 can be driven to rotate by an electric motor. Since the sprinkler equipment is set outdoors, the motor can be powered by solar energy.

[0041] The filter screen 11 is arc-shaped, which allows the garbage intercepted by the filter screen 11 to collect at the bottom of the filter screen 11.

[0042] The reference plane can be the plane shown at point Z in the figure.

[0043] The top of the first region 25 refers to the area extending upwards from the axis of the rotating disk 12 along the slope 1, while the bottom refers to the area extending downwards from the axis of the rotating disk 12 along the slope 1. Similarly, the top of the second region 24 refers to the area extending upwards from the axis of the rotating disk 12 along the slope 1, while the bottom refers to the area extending downwards from the axis of the rotating disk 12 along the slope 1.

[0044] The discharge channel 9 is used to discharge debris such as fallen rocks or leaves from the water collection channel 5. The discharge channel 9 can be an inclined channel so that the debris entering it can fall under the action of gravity.

[0045] The receiving plate 10 is used to receive garbage.

[0046] Taking the diagram as an example, initially, there is a gap between blade A and the mesh surface of filter screen 11. The rotating disk 12 rotates clockwise. When blade A enters the bottom of the first region 25, blade A moves away from the axis of the rotating disk 12, allowing it to rest against the mesh surface of filter screen 11. As the rotating disk 12 continues to rotate, blade A can push the debris gathered at the bottom of filter screen 11 towards the top of the first region 25. Since the end of filter screen 11 is located at the top of the first region 25 and is arc-shaped, this increases the filtration area of ​​filter screen 11, reduces the risk of clogging, and ensures that when blade A exits the bottom of the first region 25, debris tends to fall onto blade A. When blade A rotates to the top of the first region 25, debris can be stored between blades AB (at this time, blade D enters the bottom of the first region 25, i.e., blade D moves away from the axis of the rotating disk 12, while blades ABC move closer to the axis of the rotating disk 12).

[0047] When blade A rotates into the bottom of the first region 25, blades BCD move towards the axis of the rotating disk 12. As the rotating disk 12 continues to rotate, blade CD gradually rotates towards the second region 24, allowing the debris stored between blades CD to fall onto the receiving plate 10. The receiving plate 10 reduces the risk of debris falling back onto the filter screen 11. Furthermore, as the rotating disk 12 rotates, when blade D rotates to the receiving plate 10, the distance blade D moves towards the axis of the rotating disk 12 allows it to avoid the receiving plate 10, enabling it to pass over it. The filter element 8 cleans the filter screen 11, reducing the risk of debris clogging it and ensuring its permeability.

[0048] The rotating disk 12 can operate intermittently. When the rotating disk 12 is not operating, blade A can be located at the bottom of the first area 25. The advantage of this arrangement is that blades BC are facing the higher side of the slope 1, and some debris can be stored between blades BC. When the water between blades BC is full, the water overflows from the top of blades BC. Since blades BC are close to the axis of the rotating disk 12, there is a certain gap between blade C and the receiving plate 10 in the width direction of the slope 1, so that the water overflowing from blade C will not fall onto the receiving plate 10, reducing the risk of water waste. At the same time, since blade A is located at the bottom of the first area 25, blade A is against the mesh surface of the filter screen 11. At this time, blade A can prevent debris falling into the first area 25 from falling into the bottom of the filter screen 11. This facilitates the subsequent cleaning of debris by driving the rotating disk 12 to rotate, and also reduces the risk of excessive debris accumulating at the bottom of the filter screen 11, which would reduce the water permeability of the filter screen 11.

[0049] In some embodiments, the rotating disk 12 is provided with a mounting ring 14, and around the circumference of the mounting ring 14, a plurality of insertion holes are provided at intervals, and the blade 15 is inserted into the insertion holes.

[0050] The axial direction of the socket can extend radially along the rotating disk 12.

[0051] The blade 15 is inserted into the socket, allowing the blade 15 to move radially relative to the rotating disk 12. The side of the blade 15 closest to the rotating disk 12 can abut against the rotating disk 12, so that the rotating disk 12 and the blade 15 can form a space for storing waste.

[0052] In some embodiments, the bottom wall of the water collection channel 5 is provided with an abutment portion, which includes an arc surface 26. When the blade 15 is configured to be screwed into the bottom of the first region 25, the end of the blade 15 near the axis of the rotating disk 12 abuts against the arc surface 26.

[0053] In an embodiment where the rotating disk 12 is provided with a mounting ring 14, the abutment portion may be provided inside the mounting ring 14, with the arc surface 26 facing the inner wall of the mounting ring 14.

[0054] During the rotation of the rotating disk 12, the abutment remains stationary.

[0055] The arc surface 26 is used to control the movement of the blade 15. When a blade 15 is screwed into the bottom of the first region 25, the end of the blade 15 can abut against the arc surface 26, so that the blade 15 can move away from the axis of the rotating disk 12. Conversely, when the end of the blade 15 is screwed out of the bottom of the first region 25, the blade 15 is screwed out of the arc surface 26, so that the blade 15 can be reset.

[0056] The specific length of the arc surface 26 can be set reasonably as needed, as long as it can meet the above-mentioned control requirements for the blade 15.

[0057] In some embodiments, the filter element 8 further includes a protective sleeve 19 and four limiting portions 20. The protective sleeve 19 is disposed around the outer periphery of the four blades 15, and a first elastic member 18 is disposed between the blades 15 and the rotating disk 12. The four limiting portions 20 are movably connected to the rotating disk 12 radially, and the four limiting portions 20 are circumferentially spaced around the rotating disk 12. The limiting portions 20 are disposed between two adjacent blades 15, and a second elastic member 22 is disposed between the limiting portions 20 and the rotating disk 12.

[0058] The protective case 19 is made of a flexible and elastic material, such as rubber.

[0059] The protective sleeve 19 serves two purposes: firstly, it isolates debris, preventing it from entering the mounting ring 14 and causing the blade 15 to jam; secondly, when one blade 15 moves away from the axis of the rotating disk 12, the protective sleeve 19 drives the other three blades 15 to move closer to the axis of the rotating disk 12.

[0060] The first elastic element 18 is used to provide an elastic force to reset the blade 15.

[0061] The limiting part 20 allows the protective sleeve 19 to be set around the edge of the overall structural outline of the four blades 15, ensuring that the portion of the protective sleeve 19 between two blades 15 does not become taut, thus guaranteeing that there is space for storing waste between the two blades 15. On the other hand, since the limiting part 20 is movably connected to the rotating disk 12, when the blade 15 screwed into the first region 25 moves away from the axis of the rotating disk 12, the protective sleeve 19 tightens, and the protective sleeve 19 can push the limiting part 20 to move away from the axis of the rotating disk 12. This arrangement facilitates the full dumping of waste between the two blades 15 onto the receiving plate 10.

[0062] The second elastic element 22 is used to provide an elastic force to reset the limiting part 20. The second elastic element 22 may include a spring.

[0063] In some embodiments, the first elastic element 18 includes a sleeve 16 and an inner rod 17. The sleeve 16 is connected to the blade 15. The inner rod 17 is inserted into the sleeve 16 and connected to the rotating disk 12. A spring is provided between the inner rod 17 and the sleeve 16.

[0064] The inner rod 17 is inserted into the sleeve 16, allowing the inner rod 17 to move relative to the sleeve 16.

[0065] The spring between the inner rod 17 and the sleeve 16 is used to provide an elastic force that allows the inner rod 17 to return to its original position relative to the sleeve 16.

[0066] The inner rod 17 and the sleeve 16 work together to increase the movement accuracy of the blade 15 relative to the rotating disk 12.

[0067] In some embodiments, the rotating disk 12 is provided with a groove 21, which extends radially along the rotating disk 12, and the limiting part 20 is slidably connected to the groove 21.

[0068] The limiting part 20 is slidably connected to the slide groove 21, so that the limiting part 20 can move relative to the slide groove 21.

[0069] In some embodiments, a friction layer 23 is provided on the inner wall of the end of the slide groove 21 away from the axis of the rotating disk 12.

[0070] The friction layer 23 is used to delay the reset of the limiting part 20. That is, when the limiting part 20 moves away from the rotating disk 12, the limiting part 20 contacts the friction layer 23 on the inner wall of the slide groove 21. Then, under the action of the second elastic member 22, the limiting part 20 slowly resets until the limiting part 20 slides out of the range of the friction layer 23. Then, the limiting part 20 quickly moves towards the axis of the rotating disk 12, so that the limiting part 20 can hit the protective sleeve 19. This setting can loosen the debris between the two blades 15 and reduce the risk of debris adhering to the protective sleeve 19.

[0071] Although this design carries the risk of trash getting between the protective sleeve 19 and the limiting part 20, this risk can be reduced by properly setting the size of the limiting part 20.

[0072] In some embodiments, the limiting part 20 is connected to the covering part 13, which covers the opening of the groove 21.

[0073] The cover 13 covers the opening of the chute 21. This design prevents garbage from entering the chute 21, thereby reducing the risk of the limiting part 20 getting stuck.

[0074] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
