Description

Technical Field

[0001] This application relates to the field of greening maintenance equipment technology, and in particular to an irrigation device for greening maintenance of highway slopes. Background Technology

[0002] Greening and maintaining highway slopes is an important measure to ensure the healthy growth of vegetation on highway slopes, prevent soil erosion, and protect road safety. Greening highway slopes can protect the roadbed and stabilize the slope. Through the coverage of vegetation and the fixing effect of the root system, it can reduce soil erosion caused by rainwater. When carrying out maintenance, it is necessary to water in a timely and appropriate manner according to the growth needs of plants and climatic conditions to keep the soil moist.

[0003] Currently, irrigation for slope greening along highways is mostly done manually by standing on a water truck and manually swinging the spray nozzles to ensure the water is sprayed evenly onto the slope. However, since slopes have an angle, the water flows downwards during spraying, causing some of the water sprayed onto the slope's base to quickly flow into the ditches below, resulting in some water loss. Furthermore, highways are long, requiring a large amount of water for each irrigation session, leading to a significant overall water consumption per irrigation. Summary of the Invention

[0004] To address the aforementioned problems, this application provides an irrigation device for highway slope greening and maintenance, which can adjust the spray angle of the nozzles to reduce irrigation water loss and improve irrigation water utilization. The technical solution is as follows:

[0005] The first aspect of this application provides an irrigation device for highway slope greening maintenance, including a vehicle body, a nozzle, a support mechanism, and an adjustment mechanism. A water tank is provided on the vehicle body, and the nozzle is connected to the water tank through a water supply pipe. The support mechanism is fixed on the vehicle body and is used to support the nozzle. It includes a rotatable support shaft and a support frame connected to the free end of the support shaft. The nozzle is mounted on the support frame. The adjustment mechanism is connected to the support shaft and drives the nozzle to rotate synchronously by driving the support shaft to rotate forward or backward, thereby adjusting the spray angle of the nozzle.

[0006] For example, in one embodiment of the irrigation device for highway slope greening maintenance, the adjusting mechanism includes a swing rod, a sliding rod, and a push rod. One end of the swing rod is sleeved on the support shaft, and a first groove is provided on the swing rod along the axial direction. The sliding rod can move left and right in a straight line, and a second groove is provided on the sliding rod along the axial direction. One end of the push rod is located in the first groove, and the other end is located in the second groove to connect the swing rod and the sliding rod. When the push rod slides in a straight line along the second groove, it drives the swing rod to rotate about the push rod as an axis, and drives the support shaft and the nozzle to rotate synchronously to adjust the spray angle of the nozzle.

[0007] For example, in one embodiment of the irrigation device for greening and maintaining highway slopes, a slider is provided at the end of the push rod facing the sliding rod, and the slider is located in the second groove and slides along the second groove.

[0008] For example, in one embodiment of the irrigation device for greening and maintaining highway slopes, the adjusting mechanism further includes an A driving member for driving the slider to slide along the second chute. The A driving member includes a rotating screw disposed on the center line of the second chute. The two ends of the rotating screw are rotatably connected to the two ends of the second chute. The slider is threadedly connected to the outer wall of the rotating screw. The rotation of the rotating screw drives the slider to move linearly along the rotating screw.

[0009] For example, in one embodiment of the irrigation device for greening and maintaining highway slopes, the adjusting mechanism further includes an A-drive member for driving the slider to slide along the second chute. The A-drive member is an A-telescopic drive member fixedly installed on the sliding rod. The moving end of the A-telescopic drive member is fixedly connected to the slider to drive the slider to slide along the second chute.

[0010] For example, in one embodiment of the irrigation device for greening and maintaining highway slopes, the adjusting mechanism further includes a B-drive component that drives the sliding rod to move linearly along its axial direction. The B-drive component includes a first connecting rod, a second connecting rod, and a swing drive component. One end of the first connecting rod is rotatably connected to the end of the sliding rod via a first rotating shaft. One end of the second connecting rod is hinged to the end of the first connecting rod away from the sliding rod, and the other end is provided with a second rotating shaft. The swing drive component is fixedly connected to the middle of the second connecting rod, drives the second connecting rod to rotate around the second rotating shaft, and drives the sliding rod to move linearly along its axial direction via the first connecting rod.

[0011] For example, in one embodiment of the irrigation device for highway slope greening maintenance, the swing drive includes a turntable, a rotation drive, and a guide frame. A sliding rod is vertically provided on the edge of the turntable. The rotation drive is located at the center of the turntable and drives the turntable to rotate. The guide frame is located on one side of the turntable and is fixedly connected to the middle of the second connecting rod. A guide groove is provided on the guide frame for the sliding rod to slide. The guide groove includes an arc-shaped groove with the same radius as the turntable. Straight grooves are provided at both ends of the arc-shaped groove, and the arc-shaped groove is connected to the straight groove.

[0012] For example, in one embodiment of the irrigation device for greening and maintaining highway slopes, the adjusting mechanism further includes a B-drive member that drives the sliding rod to move linearly along its axial direction. The B-drive member is a B-telescopic drive member, and the moving end of the B-telescopic drive member is fixedly connected to the sliding rod.

[0013] For example, in one embodiment of the irrigation device for greening and maintaining highway slopes, the adjusting mechanism further includes a guide member that limits the linear movement of the sliding rod along its axial direction. The guide member includes a guide rail, and the sliding rod is slidably connected to the guide rail.

[0014] For example, in one embodiment of the irrigation device for greening and maintaining highway slopes, a mounting frame fixed to the rear of the vehicle body is also provided. The mounting frame includes a mounting plate that is perpendicular to the vehicle body floor, and the support mechanism and the adjustment mechanism are both perpendicular to the mounting plate.

[0015] The beneficial effects of the irrigation device for highway slope greening maintenance provided in some embodiments of this application are as follows: This application drives the sliding rod to move quickly to one side of the support shaft and then move in the opposite direction through the B driving component. After the sliding rod moves in the opposite direction, it pauses for a period of time before moving to one side of the support shaft. During this process, the irrigation water sprayed by the nozzle covers the slope greening. When the sliding rod stops moving, the spraying direction of the nozzle is towards the top of the slope greening, so that the sprayed irrigation water flows down along the top of the slope, making full use of the water flow to irrigate the slope greening comprehensively, and reducing the time when the irrigation water is sprayed directly to the greening at the bottom of the slope, reducing the loss of irrigation water and improving the utilization rate of irrigation water.

[0016] The slider is driven by drive component A to move along the length of the sliding rod. When the slider moves, it drives the push rod to move. The push rod pushes against the inner wall of the groove, which in turn drives the swing rod and the support shaft to rotate. When the support shaft rotates, it drives the nozzle to rotate through the support frame, thereby adjusting the spray angle of the nozzle and thus adjusting the initial spray angle of the nozzle, improving the practicality of the device.

[0027] This application provides an irrigation device for the maintenance of green slopes along highways, such as... Figure 1-5 As shown, the device includes a vehicle body 1, a nozzle 3, a mounting bracket 4, a support mechanism 5, and an adjustment mechanism 6. A water tank 2 is installed on the vehicle body, and a water pump (not shown in the figure) is installed inside the water tank 2. The output end of the water pump is connected to a water pipe 21. The nozzle 3 is fixedly installed at the end of the water pipe 21 away from the water tank 2. A mounting bracket 4 is installed at the rear of the vehicle body 1. The mounting bracket 4 is detachably connected to the vehicle body 1 by bolts. The mounting bracket 4 includes a mounting plate 41 that is vertically mounted on the bottom plate of the vehicle body 1. The support mechanism 5 and the adjustment mechanism 6 are both vertically mounted on the mounting plate 41.

[0028] The support mechanism 5 is fixed on the vehicle body 1 and is used to support the nozzle 3. It includes a rotatable support shaft 51 and a support frame 52 connected to the free end of the support shaft 51. The nozzle 3 is mounted on the support frame 52.

[0029] The adjustment mechanism 6 is connected to the support shaft 51 and drives the nozzle 3 to rotate synchronously by driving the support shaft 51 to rotate in the forward or reverse direction, so as to adjust the spray angle of the nozzle 3.

[0030] The irrigation device for highway slope greening maintenance disclosed in this application uses a mounting frame 4 installed at the rear of the vehicle body 1. A support mechanism 5 is set on the mounting frame 4 to fix the nozzle 3. The support shaft 51 is driven to rotate forward or backward by the adjustment mechanism 6, which drives the nozzle 3 to pitch and rotate, thereby adjusting the spray angle of the nozzle 3. This overcomes the defect of existing highway slope greening irrigation where the spray angle is adjusted by manually swinging the spray nozzle while standing on a water truck.

[0031] Among them, the support mechanism 5 is located near the side edge of the mounting plate 41. One end of the support shaft 51 is rotatably connected to the mounting plate 41, and the other end of the support shaft 51 away from the mounting plate 41 is fixedly connected to the support frame 52. The support frame 52 is provided with a through hole for the nozzle 3 to pass through, and the nozzle 3 passes through the through hole and is fixedly installed on the support frame 52.

[0032] For example, in one embodiment of the irrigation device for highway slope greening and maintenance, such as Figure 2-3 As shown, the adjustment mechanism 6 includes a swing rod 61, a sliding rod 64, and a push rod 62. One end of the swing rod 61 is sleeved on the support shaft 51. A first groove 611 is provided on the swing rod 61 along its axial direction, and the length of the first groove 611 is the same as that of the swing rod 61 along its axial direction. The sliding rod 64 is horizontally arranged on the mounting plate 41, with one end close to the support shaft 51. The sliding rod 64 can move left and right in a straight line along its axial direction. A second groove 641 is provided on the sliding rod 64 along its axial direction. One end of the push rod 62 is located in the first groove 611, and the other end is located in the second groove 641 to connect the swing rod 61 and the sliding rod 64. When the push rod 62 slides in a straight line along the second groove 641, it drives the swing rod 61 to rotate around the push rod 62 as an axis, and drives the support shaft 51 and the nozzle 3 to rotate synchronously to adjust the spray angle of the nozzle 3.

[0033] For example, in one embodiment of the irrigation device for highway slope greening and maintenance, such as Figure 3 , 6 As shown, a slider 63 is provided at the end of the push rod 62 facing the sliding rod 64. The slider 63 is located in the second groove 641 and slides along the second groove 641.

[0034] For example, in one embodiment of the irrigation device for highway slope greening and maintenance, such as Figure 3 , 6 As shown, the adjustment mechanism 6 also includes an A drive member for driving the slider 63 to slide along the second slide groove 641. The A drive member includes a rotating screw 66 disposed on the center line inside the second slide groove 641. The two ends of the rotating screw 66 are rotatably connected to the two ends of the second slide groove 641. The slider 63 is threadedly connected to the outer wall of the rotating screw 66. The slider 63 is driven to move linearly along the rotating screw 66 by the rotation of the rotating screw 66.

[0035] For example, in one embodiment of the irrigation device for greening and maintenance of highway slopes, the adjusting mechanism 6 further includes an A-drive member that drives the slider 63 to slide along the second slide groove 641. The A-drive member is an A-telescopic drive member fixedly installed on the sliding rod 64. The A-telescopic drive member is a telescopic cylinder or a hydraulic cylinder. The moving end of the A-telescopic drive member is fixedly connected to the slider 63. The slider 63 is driven to slide along the second slide groove 641 by the extension and retraction of the moving end of the A-telescopic drive member.

[0036] The sliding rod 64 is driven by drive component B to move linearly left and right along the axial direction. As the sliding rod 64 moves linearly, it drives the slider 63 to move via drive component A. The slider 63 moves, causing the push rod 62 to move. The push rod 62 pushes against the inner wall of the groove 611, thereby causing the swing rod 61 and the support shaft 51 to rotate. When the support shaft 51 rotates, it drives the nozzle 3 to rotate via the support frame 52. Thus, the rotation of the nozzle 3 can be controlled by the movement of the sliding rod 64, ensuring that the irrigation water sprayed by the nozzle 3 covers the slope greening. Furthermore, drive component B can drive the sliding rod 64 to move quickly to one side of the support shaft 51 and then in the opposite direction. After the sliding rod 64 moves in the opposite direction, it pauses for a period of time before moving back towards the support shaft 51. When the support shaft 51 moves to one side, during this process, when the sliding rod 64 moves to the side of the support shaft 51, the swing rod 61 will drive the nozzle 3 to rotate rapidly downward through the support shaft 51 and the support frame 52. When the sliding rod 64 moves in the opposite direction, the swing rod 61 will drive the nozzle 3 to rotate rapidly upward through the support shaft 51 and the support frame 52, so that the irrigation water sprayed by the nozzle 3 covers the slope greening. When the sliding rod 64 stops moving, the spraying direction of the nozzle 3 is towards the top of the slope greening, so that the sprayed irrigation water flows down along the top of the slope, making full use of the water flow to irrigate the slope greening, reducing the time when the irrigation water is sprayed directly to the greening at the bottom of the slope, reducing the loss of irrigation water, and improving the utilization rate of irrigation water.

[0037] Furthermore, the slider 63 can be driven to move along the length of the sliding rod 64 via the A drive component. When the slider 63 moves, it drives the push rod 62 to move. The push rod 62 pushes against the inner wall of the slide groove 611, thereby driving the swing rod 61 and the support shaft 51 to rotate. When the support shaft 51 rotates, it drives the nozzle 3 to rotate through the support frame 52, thereby adjusting the spray angle of the nozzle 3 and thus adjusting the initial spray angle of the nozzle 3, improving the practicality of the device.

[0038] For example, in one embodiment of the irrigation device for highway slope greening and maintenance, such as Figure 3 As shown, the B-drive component that drives the sliding rod 64 to move linearly along its axial direction includes a first link 68, a second link 67, and a swing drive component 69: one end of the first link 68 is rotatably connected to the end of the sliding rod 64 via a first rotating shaft 681; one end of the second link 67 is hinged to the end of the first link 68 away from the sliding rod 64, and the other end is provided with a second rotating shaft 671; the swing drive component 69 is fixedly connected to the middle of the second link 67 to drive the second link 67 to rotate around the second rotating shaft 671, and drives the sliding rod 64 to move linearly along its axial direction via the first link 68.

[0039] For example, in one embodiment of the irrigation device for highway slope greening and maintenance, such as Figure 3 , 7As shown, the swing drive 69 includes a turntable 692, a rotary drive 691, and a guide frame 694. The turntable 692 has a sliding rod 693 hanging vertically on its edge. The rotary drive 691 is a rotary cylinder or a motor, and is fixedly mounted on the mounting plate 41. The output shaft of the rotary drive 691 passes through the mounting plate 41 and is fixedly connected to the center of the turntable 692 to drive the turntable 692 to rotate. The guide frame 694 is located on one side of the turntable 692 and is fixedly connected to the middle of the second connecting rod 67. The guide frame 694 has a guide groove 695 for the sliding rod 693 to slide on. The guide groove 695 includes an arc-shaped groove with the same radius as the turntable 692, and straight grooves are provided at both ends of the arc-shaped groove. The arc-shaped groove and the straight groove are connected.

[0040] According to the above embodiment, when the rotary drive 691 drives the turntable 692 to rotate, the turntable 692 moves via the slide rod 693. The slide rod 693 moves along the inner wall of the guide groove 695 on the guide frame 694. Since the guide groove 695 consists of an arc-shaped groove and two straight grooves, initially, the slide rod 693 slides along the arc-shaped groove on the guide groove 695. At this time, the slide rod 693 cannot push the guide frame 694 to move, that is, the second connecting rod 67 cannot rotate around the second rotating shaft 671. As the slide bar 693 rotates, it moves out of the arc-shaped groove and into the straight groove at the upper end. The slide bar 693 pushes against the groove wall, causing the guide frame 694 to move. At this time, the guide frame 694 drives the second connecting rod 67 to rotate around the axis of the second rotating shaft 671. The second connecting rod 67, through the first connecting rod 68, drives the slide bar 64 to move towards the support shaft 51. After the slide bar 693 moves out of the straight groove at the upper end and into the arc-shaped groove, it pushes against the inner wall of the arc-shaped groove. When the guide frame 694 moves, it drives the second connecting rod 67 to rotate around the axis of the second rotating shaft 671. The second connecting rod 67 drives the sliding rod 64 to move in the opposite direction through the first connecting rod 68. When the sliding rod 693 moves out of the arc-shaped groove and into the straight groove at the lower end, the sliding rod 693 also drives the guide frame 694 to move by pushing against the inner wall of the straight groove. Similarly, the sliding rod 64 continues to move in the opposite direction. When the sliding rod 693 moves out of the straight groove at the lower end and into the arc-shaped groove, the sliding rod 64 does not move. This cycle is repeated, so that the swing rod 61 drives the nozzle 3 to rotate rapidly upward and downward through the support shaft 51 and the support frame 52. This allows the irrigation water sprayed by the nozzle 3 to cover the slope greening, and allows the spraying direction of the nozzle 3 to pause for a period of time when it is facing the top of the slope greening, so that the sprayed irrigation water can flow downward to irrigate the greening at the bottom of the slope, improve the utilization rate of irrigation water, and reduce the loss of irrigation water.

[0041] For example, in one embodiment of the irrigation device for greening and maintenance of highway slopes, the adjustment mechanism 6 further includes a B-drive component that drives the sliding rod 64 to move linearly along its axial direction. The B-drive component is a B-telescopic drive component. The moving end of the B-telescopic drive component is fixedly connected to the sliding rod 64. The B-telescopic drive component is fixedly installed on the mounting frame 4. The sliding rod 64 is moved by the extension and retraction of the moving end of the B-telescopic drive component.

[0042] For example, in one embodiment of the irrigation device for highway slope greening and maintenance, such as Figure 2-3 As shown, the adjustment mechanism 6 also includes a guide member that limits the linear movement of the sliding rod 64 along its axial direction. The guide member includes a guide rail 65, and the sliding rod 64 is slidably connected to the guide rail 65. The movement of the sliding rod 64 is limited by the guide rail 65, making the movement of the sliding rod 64 more stable and smooth.

[0043] In one embodiment of the present invention, a corresponding control unit can also be provided for cooperative use. This control unit can be any type of controller connected to the electrical components in this application, thereby controlling the start-up and shutdown of each electrical component. This part is prior art. Here, a microcontroller can be provided as the control unit for demonstration. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., equivalent to a miniature computer. Compared with general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantage is its small size, which can be placed inside instruments, but it has small storage capacity, simple input / output interfaces, and low power consumption.

[0044] Although the embodiments of this application have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this application. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this application is not limited to the specific details and the illustrations shown and described herein.
