Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, specifically to a road maintenance anti-skid abrasion material spreader. Background Technology

[0002] Road maintenance ensures the safety, smooth flow, and comfort of highways. Anti-skid and abrasion-resistant materials used for maintenance mainly include ceramic particles, modified epoxy resin, and corundum aggregate. These materials have excellent anti-skid properties and durability, and are suitable for various road maintenance needs.

[0003] Application No. 202120621972.8 discloses a gravel spreader for road repair. It features a flap inside the gravel storage hopper. When the gravel level in the hopper is low, a first hydraulic cylinder supports the flap upwards, causing it to tilt the gravel from the right side of the hopper towards the spreading opening, preventing gravel from being left inside the hopper and facilitating spreading. An adjusting plate is installed inside the spreading opening. During gravel spreading, a second hydraulic rod pushes the adjusting plate to a suitable angle, allowing adjustment of the distance between the two adjusting plates and thus the width of the gravel spread, making it suitable for use on roads of different widths.

[0004] In the aforementioned application, the material is discharged directly from the spray nozzle. The material falls slowly and is prone to blockage, which affects the material discharge effect. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5This utility model provides a technical solution: a road maintenance anti-skid and abrasion-resistant material spreader, including a transport vehicle 1. A carriage 2 is rotatably connected to the top of the transport vehicle 1 via a hinge. A spreading pipe 3 is fixedly connected to the bottom of the carriage 2 and to one side of the transport vehicle 1. A groove 21 is formed inside the transport vehicle 1, and a hydraulic component 22 is rotatably connected inside the groove 21. The hydraulic component 22 includes a hydraulic rod. The bottom plate of the carriage 2 is rotatably connected to the output end of the hydraulic rod, allowing the hydraulic rod to push the carriage 2 to tilt, causing the material to flow into the spreading pipe 3 for easy discharge. A discharge pipe 4 is sleeved on the outside of the spreading pipe 3, rotatably connected to the spreading pipe 3. Two adjusting plates 5 are rotatably connected inside the discharge pipe 4, and an adjuster is installed on one side of the discharge pipe 4. 6. The regulator 6 has two rotating shafts 29 internally connected. Worm gears 7 are mounted on the outer sides of both shafts 29. Worms 8 are rotatably connected to the bottom of the two worm gears 7 via bearings inside the regulator 6. The two worm gears 7 mesh with the two worms 8 respectively, and the threads of the two worms 8 are in opposite directions. The two shafts 29 are fixedly connected to one end of each of the two adjusting plates 5. The two worms 8 are fixedly connected to each other. The meshing of the two worm gears 7 with the two worms 8 causes the two adjusting plates 5 to rotate simultaneously, either upwards or downwards, adjusting the angle and distance between the two adjusting plates 5 to control the material spreading range. A self-locking motor 9 is mounted on one side of the regulator 6. The output end of the self-locking motor 9 is connected to one of the... A worm gear 8 is fixedly connected, providing power for the rotation of the worm gear 8 and worm wheel 7. A support frame 10 is fixedly connected to the bottom of the carriage 2, located between the transport vehicle 1 and the discharge pipe 4. A bracket 11 is installed on one side of the support frame 10. A turntable 12 is rotatably connected to one side of the bracket 11. An adjusting rod 13 is rotatably connected to one side of the turntable 12. One end of the adjusting rod 13 is rotatably connected to the discharge pipe 4. A first motor 14 is fixedly installed on the outer wall of the bracket 11. The output end of the first motor 14 is fixedly connected to the turntable 12, driving the turntable 12 to rotate. This, in conjunction with the rotational connection of the discharge pipe 4 to the spreading pipe 3 and one end of the adjusting rod 13, causes the adjusting rod 13 to pull the adjusting plate 5 to swing repeatedly as the turntable 12 rotates. This facilitates faster material discharge and prevents blockage. A water tank 23 is installed on one side of vehicle 2, and a water pump 24 is installed at the bottom of the water tank 23. The input and output ends of the water pump 24 are connected to an inlet pipe 25 and a drain pipe 26, respectively. One end of the inlet pipe 25 is connected to the inside of the water tank 23, and the output end of the drain pipe 26 is located between the vehicle body 2 and the discharge pipe 4 and is fixedly connected to an atomizing nozzle 27. Under the action of the water pump 24, the water in the water tank 23 can be guided through the inlet pipe 25 and the drain pipe 26 to the atomizing nozzle 27 and then sprayed outward, which is convenient for dust suppression when spreading materials. A liquid inlet pipe 28 is fixedly connected to the top of the water tank 23 to facilitate the replenishment of water in the water tank 23. The transport vehicle 1 is equipped with an independent power supply that provides power to the self-locking motor 9, the first motor 14, the hydraulic component 22, and the water pump 24.One end of the carriage 2 is hinged to a first door 15 and a second door 16. A positioning element 17 is installed on one side of the first door 15, and an arc-shaped groove 20 is formed inside the positioning element 17. A support shaft 18 is rotatably connected to one side of the second door 16, and an arc-shaped bolt 19 is fixedly connected to one side of the support shaft 18. One end of the arc-shaped bolt 19 engages with the arc-shaped groove 20 and can slide, allowing the bolt 19 to engage or disengage with the arc-shaped groove 20 within the positioning element 17 as the support shaft 18 rotates. This fixes or separates the first door 15 and the second door 16, facilitating their rapid opening and closing. The self-locking motor 9, the first motor 14, and other electrical equipment are powered by a battery inside the transport vehicle 1, and the corresponding controller is located in the driver's cab.

[0023] In summary, this road maintenance anti-skid abrasion material spreader operates by using a self-locking motor 9 to drive two worm gears 8 within the adjuster 6 to rotate. These worm gears 8 mesh with the outer worm wheels 7 of the two rotating shafts 29, and the two rotating shafts 29 are connected to two adjusting plates 5 within the discharge pipe 4. This causes the two adjusting plates 5 to rotate at corresponding angles, opening the discharge pipe 4. Simultaneously, by adjusting the distance between one end of the two adjusting plates 5 and the material's falling range, the hydraulic assembly 22 tilts the truck bed 2, causing the material inside to flow into the spreading pipe 3 and the discharge pipe 4 and be discharged. The first motor 14 can be activated as needed. The drive turntable 12 rotates. Since the discharge pipe 4 is located outside the spreading pipe 3 and is rotatably connected to the spreading pipe 3, the end of the adjusting rod 13 on one side of the turntable 12 is rotatably connected to the discharge pipe 4. This causes the adjusting rod 13 to pull the discharge pipe 4 to swing repeatedly as the turntable 12 rotates, thus accelerating the discharge of materials. In cases where a large amount of material needs to be spread, the support shaft 18 on the second door 16 can be rotated to pull out the arc-shaped bolt 19 on one side from the positioning piece 17 on the first door 15, thereby releasing the fixation of the first door 15 and the second door 16, opening the carriage 2, and directly dumping out the material.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
