Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway dust suppression spraying technology, and in particular to a dust suppression spraying device for highway maintenance operations. Background Technology
[0002] Dust suppression spraying on highways is an environmental protection measure used to control and reduce dust pollution generated during highway construction and maintenance. Water is pumped from a storage tank, diverted through a three-way pipe into a connecting pipe, and then sprayed out from a spray cannon to humidify and suppress dust.
[0003] For example, a highway maintenance dust suppression spraying device, publication number CN220619726U, first moves the device to a designated area, adjusts the vertical spraying angle of the mist cannon, and finally starts the motor and water pump to deliver water from the water tank to the mist cannon and spray it out. The motor can drive the rotating rod to rotate, and under the meshing action between the bevel gears, it drives the second shaft to rotate. The rotation of the second shaft drives the first connecting rod to rotate. Utilizing the hinge action between the first and second connecting rods, the sliding cooperation between the sliding block and the sliding groove, the hinge action between the sliding block and the second connecting rod, the sliding cooperation between the slider and the limiting groove, and the hinge cooperation between the second connecting rod and the slider, the disc can be driven to rotate in a regular forward and reverse direction, thereby causing the mist cannon to swing back and forth automatically.
[0004] However, the dimensions of the bevel gear, connecting rod one, connecting rod two, and sliding groove are fixed. Therefore, in actual use, connecting rod one and connecting rod two can only drive the disc to swing in a fixed pattern, that is, the swing amplitude is fixed. Therefore, in actual use, when the swing amplitude of the fog cannon exceeds the road width, it is easy to waste the sprayed fog. When the swing amplitude of the fog cannon is less than the road width, the sprayed fog cannot cover the width of the road. Utility Model Content
[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a dust suppression spraying device for highway maintenance operations.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dust suppression spraying device for highway maintenance operations, comprising a fixed base, a chassis rotatably connected to one side of the upper surface of the fixed base, an insert shell fixedly connected to the center of the top of the chassis, an insert post inserted into the insert shell, the top of the insert post being U-shaped and hinged to an atomizing cannon that swings longitudinally, a guide block slidably relative to the air outlet of the atomizing cannon being disposed in the fixed base directly below the chassis, a connecting handle rotatably connected to the top of the guide block, and connecting frames fixedly connected to the top edges of one of the opposite sides, a sliding member being disposed through the two connecting frames, the connecting handle rotating within the two connecting frames and extending upward in a columnar shape at one end and slidingly connected to the bottom edge of the sliding member, the center of the top edge of the sliding member being columnar and a swing frame having one end fixed to the center of the bottom of the chassis being sleeved on the columnar part of the top edge of the sliding member.
[0007] Preferably, the chassis is rotatably connected to a vertically arranged screw near the center, and the side of the insert is fixedly connected to an internally threaded cylinder that is threadedly connected to the screw.
[0008] Preferably, a motor for driving the screw rotation is embedded in the top of the chassis, and a motor is also fixedly connected to the top edge of the guide block, and the motor spindle on the guide block is fixed to the other end of the connecting handle.
[0009] Preferably, a water tank is installed on the other side of the upper surface of the fixed base, and a water pump is installed on the upper surface of the fixed base between the water tank and the chassis. The water pump inlet is connected to the bottom of the water tank, and the water outlet is connected to the air inlet of the atomizing cannon through a hose.
[0010] Preferably, elastic ropes are fixedly connected to one end of each side edge of the swing frame at the center of the chassis, and the other end of the elastic ropes is symmetrically arranged about the guide block and installed on the inner wall of the fixed seat.
[0011] Preferably, a guide rail that passes through the guide block is fixedly connected inside the fixed base at a position directly below the chassis, and an electric push rod for connecting the guide block is fixedly connected to the upper surface of the guide rail.
[0012] Preferably, the guide rail is arranged parallel to the electric push rod, and the length direction of the guide rail extends along the length direction of the fixed seat and is perpendicular to the central axis of the water tank.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, the connecting handle makes a circular motion, which drives the sliding part that cooperates with it to swing back and forth under the guidance of the two connecting frames. Since the columnar part at the top of the sliding part is inserted into the swing frame, the swing frame swings back and forth by moving the sliding part back and forth. The swing amplitude of the swing frame will also change according to the distance between the sliding part and the center of the chassis. Therefore, by controlling the swing amplitude of the swing frame, the swing amplitude of the turntable driving the insert shell, the insert post and the atomizing cannon installed on the top of the insert post can be adjusted. This makes it easy to adjust according to the width of the road surface and ensure that the width of the entire road surface is covered at one time.
[0015] 2. In this utility model, when the swing frame swings, the elastic rope on one side will stretch elastically. Therefore, the elastically stretched elastic rope provides additional tension when the swing frame returns to its original position, reducing the load on the sliding parts and connecting handle.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] like Figure 1-5 As shown, a dust suppression spraying device for highway maintenance includes a fixed base 1. A chassis 10 is rotatably connected to one side of the upper surface of the fixed base 1. A housing 5 is fixedly connected to the center of the top of the chassis 10. A post 8 is inserted into the housing 5. The top of the post 8 is U-shaped and hinged to a longitudinally swinging atomizing cannon 4. The atomizing cannon 4 and the post 8 are connected by a hinged electric push rod 12. That is, the longitudinal swinging of the atomizing cannon 4 can be achieved by extending and retracting the additionally installed electric push rod 12. A guide block 15 is provided in the fixed base 1 directly below the chassis 10, which slides horizontally relative to the air outlet of the atomizing cannon 4. A connecting handle 18 is rotatably connected to the top of the guide block 15, and connecting frames 17 are fixedly connected to the top edges of both opposite sides. Sliding elements 16 are provided through the two connecting frames 17. The connecting handle 18 rotates within the two connecting frames 17 and extends upward in a columnar shape at one end, slidingly connected to the bottom edge of the sliding element 16. The top edge of the sliding member 16 is columnar, and one end of the columnar part of the top edge is fitted with a swing frame 13 fixed to the bottom center of the chassis 10. In actual use, one end of the swing frame 13 is fixed to the bottom of the rotating chassis 19. Therefore, by controlling the swing amplitude of the swing frame 13, the chassis 10 can drive the insertion shell 5, the insertion post 8, and the atomizing cannon 4 installed on the top of the insertion post 8 to adjust the swing amplitude. Thus, the connecting handle 18 makes a circular motion, which drives the sliding member 16 to swing back and forth under the guidance of the two connecting frames 17. Since the columnar part at the top of the sliding member 16 is inserted into the swing frame 13, the swing frame 13 swings back and forth by moving the sliding member 16 back and forth. The swing amplitude of the swing frame 13 also changes according to the distance of the sliding member 16 from the center of the chassis 10. That is, the closer the sliding member 16 is to the center of the chassis 10, the greater the swing amplitude of the swing frame 13, and the greater the left and right swing amplitude of the atomizing cannon 4.
[0025] Furthermore: A vertically arranged screw 7 is rotatably connected near the center of the chassis 10. An internally threaded cylinder 6, which is threadedly connected to the screw 7, is fixedly connected to the side of the insert post 8. A motor 9 for driving the screw 7 to rotate is embedded in the top of the chassis 10. The screw 7 is driven to rotate by the motor 9 on the chassis 10. The internally threaded cylinder 6 is raised and lowered as the screw 7 rotates, which can drive the height adjustment of the insert post 8 and the atomizing cannon 4. A motor 9 is also fixedly connected to the top edge of the guide block 15. The main shaft of the motor 9 on the guide block 15 is fixed to the other end of the connecting handle 18. The motor 9 on the guide block 15 drives the connecting handle 18 to rotate.
[0026] Furthermore: A water tank 2 is installed on the other side of the upper surface of the fixed base 1, and a water pump 3 is installed on the upper surface of the fixed base 1 between the water tank 2 and the chassis 10. The water inlet of the water pump 3 is connected to the bottom of the water tank 2, and the water outlet is connected to the air inlet of the atomizing cannon 4 through a hose, so as to achieve smooth water supply to the atomizing cannon 4.
[0027] Furthermore, elastic ropes 11 are fixedly connected to one end of each side of the swing frame 13 away from the center of the chassis 10. The other end of the elastic ropes 11 is symmetrically arranged about the guide block 15 and installed on the inner wall of the fixed base 1. When the swing frame 13 swings, the elastic rope 11 on one side will stretch elastically. Therefore, the elastic rope 11 that stretches elastically provides additional tension when the swing frame 13 resets, reducing the load on the slider 16 and the connecting handle 18.
[0028] Furthermore: A guide rail 14 is fixedly connected inside the fixed base 1, located directly below the chassis 10, and passes through the guide block 15. An electric push rod 12 for connecting the guide block 15 is fixedly connected to the upper surface of the guide rail 14. The guide rail 14 and the electric push rod 12 are arranged parallel to each other, and the length direction of the guide rail 14 extends along the length direction of the fixed base 1 and is set perpendicular to the central axis of the water tank 2. By extending and retracting the electric push rod 12, the guide block 15 can be moved along the surface of the guide rail 14, thereby adjusting the distance between the sliding member 16 and the center of the chassis 10.
[0029] Working principle: During use, the guide block 15 slides on the surface of the guide rail 14 by extending and retracting the electric push rod 12 according to the width of the road surface. This synchronously drives the motor 9, connecting handle 18, and sliding member 16 on the guide block 15 to move, thereby adjusting the distance between the sliding member 16 and the center of the chassis 10. The motor 9 on the guide block 15 drives the connecting handle 18 to rotate. The connecting handle 18 makes a circular motion, which drives the sliding member 16 to swing back and forth under the guidance of the two connecting frames 17. Since the columnar part at the top of the sliding member 16 is inserted into the swing frame 13, the back-and-forth movement of the sliding member 16 realizes the back-and-forth swing of the swing frame 13, thus enabling the chassis 10 to drive the atomizing cannon 4 to swing left and right.
[0030] The wiring diagrams of the water pump 3, atomizing cannon 4, motor 9, and electric push rod 12 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the water pump 3, atomizing cannon 4, motor 9, and electric push rod 12 will not be explained in detail.
[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
