Description

Technical Field

[0001] This invention relates to a composite snow-melting device, and more particularly to a composite snow-melting device for spreading de-icing agents to prevent road blockages, belonging to the field of design and manufacturing technology of road blockage prevention, snow removal and smooth traffic equipment. Background Technology

[0002] De-icing agents, as the name suggests, are chemicals that lower the melting temperature of ice and snow. Common de-icing agents are readily available and inexpensive, primarily composed of potassium acetate and chloride salts, and are classified based on these two components. De-icing agents melt snow on roads by lowering the melting temperature, facilitating road clearance and showing significant effects when applied. However, they are also hazardous. Studies have found that de-icing agent residues can corrode road surfaces and car tires. Currently, in northern regions with prolonged winters, the primary method for clearing ice and snow from roads is still using sand and snowplows, supplemented by de-icing agents, to ensure smooth traffic flow. De-icing agents require the use of de-icing agent application devices.

[0003] Existing road snow melting devices are ineffective in cold winter weather with heavy snow accumulation. Too much snow on roads can hinder normal travel, making it difficult for vehicles to move and causing inconvenience for people. Generally, road snow melting is done manually by spreading de-icing agents, which is labor-intensive, inefficient, and not very effective for large-scale snow melting operations. Therefore, a road anti-blockage de-icing agent snow melting device is needed to improve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a composite snow-melting device for spreading de-icing agents to prevent road blockage, which has a relatively high degree of mechanization and can significantly improve snow removal efficiency and effect.

The solid de-icing agent dispensing assembly is connected to an inclined funnel-shaped output interface through the receiving bin. The solid de-icing agent located in the receiving bin is thrown out from the rear of the movable base frame through the solid de-icing agent dispensing component group arranged below the receiving bin, in cooperation with the solid de-icing agent dispensing drive motor.

[0011] A preferred embodiment of the above solution is that the solid de-icing agent spraying assembly includes a main solid de-icing agent spraying disc and a secondary solid de-icing agent spraying disc that are adapted to each other.

The solid de-icing agent spraying drive motor is a fixed-isolation drive servo motor, and the main solid de-icing agent spraying disc is fixedly mounted on the power output shaft of the fixed-isolation drive servo motor. During the solid de-icing agent spraying process, the main and secondary solid de-icing agent spraying discs, located below the receiving hopper, spray the solid de-icing agent through the spreading grooves in cooperation with the fixed-isolation drive servo motor.

[0012] Furthermore, the liquid de-icing agent spraying assembly includes a liquid de-icing agent spraying component group, a liquid de-icing agent conveying component group, and a liquid de-icing agent spraying drive motor. The liquid de-icing agent spraying component group is connected to a cuboid storage tank through the liquid de-icing agent conveying component group.

The de-icing agent in the de-icing agent storage component 2 is spread onto the road surface requiring snow melting via the de-icing agent spreading system 3, in cooperation with the movable base frame 1. The technical solution provided in this application involves setting up a composite snow-melting device including a movable base frame, a de-icing agent storage component, and a de-icing agent spreading system, with both the de-icing agent storage component and the de-icing agent spreading system arranged on the movable base frame; then, the de-icing agent in the de-icing agent storage component is spread onto the road surface requiring snow melting via the de-icing agent spreading system, in cooperation with the movable base frame. In this way, when the road surface is impassable due to heavy snow accumulation or when it is not safe to pass, the de-icing agent can be placed in the de-icing agent storage component and then conveniently and quickly spread to the areas on the road that need snow melting and clearing by moving the movable base frame. This greatly reduces the workload of manual de-icing agent spreading in existing technologies, lowers labor intensity, and at the same time, replacing manual de-icing agent spreading with machinery can significantly improve the degree of mechanization, ensure the uniformity and effectiveness of spreading, and achieve the goal of significantly improving snow removal efficiency and effect.

[0023] In the above embodiments, to facilitate movement and application of different de-icing agents, the movable base 1 described in this application is a car or a combination vehicle including a trailer and a cab.

The liquid de-icing agent spraying assembly 12 includes a liquid de-icing agent spraying component group 19, a liquid de-icing agent conveying component group 20, and a liquid de-icing agent spraying drive motor 21. The liquid de-icing agent spraying component group 19 is connected to a cuboid storage tank through the liquid de-icing agent conveying component group 20. The liquid de-icing agent located in the cuboid storage tank is sprayed out from the rear of the movable base frame 1 through the liquid de-icing agent spraying component group 19 in cooperation with the liquid de-icing agent conveying component group 20 and the liquid de-icing agent spraying drive motor 21. Correspondingly, the solid de-icing agent spraying assembly 14 includes a main solid de-icing agent spraying disc 16 and a secondary solid de-icing agent spraying disc 17 that are adapted to each other. Multiple spreading grooves 18 are evenly distributed circumferentially on both the main solid de-icing agent spraying disc 16 and the secondary solid de-icing agent spraying disc 17. The solid de-icing agent spraying drive motor 15 is a fixed-isolation drive servo motor, and the main solid de-icing agent spraying disc 16 is fixedly mounted on the power output shaft of the fixed-isolation drive servo motor. During the solid de-icing agent spraying process, the main solid de-icing agent spraying disc 16 and the secondary solid de-icing agent spraying disc 17, located below the receiving hopper 13, spray the solid de-icing agent through the spreading grooves 18 in cooperation with the fixed-isolation drive servo motor. The liquid solvent spraying drive motor 21 is a liquid solvent spraying drive servo motor. The liquid solvent delivery assembly 20 includes a delivery pump 22, a valve plate 23, a drive linkage 24, a sliding groove 25, an output connector 26, and a mounting base 27. The two ends of the delivery pump 22 are respectively connected to a cuboid-shaped liquid storage tank and the sliding groove 25. The two ends of the output connector 26 are respectively connected to the sliding groove 25 and the liquid solvent spraying assembly 19.

The drive connecting rod 24 is connected to a set of adjusting nuts 33. Each spray head 28 is arranged one-to-one on the material output end of each hollow tube 30. The middle and rear parts of each hollow tube 30 are connected one-to-one to each tap 34 through each set of sliding sleeves 29 in cooperation with the rotating shaft 32. Another adjusting nut 33 installed at the lower end of the rotating shaft 32 is screwed onto the other end of the double-ended adjusting screw 31. The ends of each hollow tube 30 are movably hinged to the mounting base 27.

[0025] In summary, the composite snow-melting device provided in this application also has the following advantages:

[0026] 1. By starting the first servo motor, the first solid agent spreading disc is driven to rotate. At the same time, the first solid agent spreading disc drives the second solid agent spreading disc to rotate through meshing teeth, thus spraying out solid de-icing agent. The spraying range can be adjusted by adjusting the speed, which can facilitate the spraying of solid de-icing agent and improve work efficiency.

[0027] 2. The water pump draws the liquid de-icing agent into the sliding trough, then into the tap joint, which connects to multiple hollow tubes via hoses. The agent is then sprayed out through the spray nozzles. The third servo motor can be activated to rotate the lead screw. Because the thread density between the lead screw and the second nut is less than that between the lead screw and the first nut, the second nut moves faster than the first nut. Furthermore, since the threads on both sides of the lead screw are in opposite directions, the second and first nuts move in opposite directions. When the second nut moves towards the center, it moves the mounting plate, causing the sliding sleeve to move on the surface of the hollow tube, causing the hollow tube to rotate and expand in a fan shape. The sliding sleeve also rotates along with the shaft, increasing the spraying range. Simultaneously, the first nut, via the connecting rod, drives the valve plate to open the outlet inside the sliding trough, increasing the drainage volume. Conversely, operating in the opposite direction reduces the spraying range and drainage volume, facilitating the application of the liquid de-icing agent and improving work efficiency.

[0045] Please see Figure 1-5This application provides a technical solution: a de-icing agent spreading device for preventing road blockage, comprising a vehicle body, a storage bin at the upper end of the vehicle body, a cone-shaped lower end of the storage bin, a rotatable feeding rod at the lower outlet of the storage bin, a receiving bin connected to the lower end of the storage bin, a first solid agent spreading disc rotatably disposed inside the receiving bin, a second solid agent spreading disc driven to one side of the first solid agent spreading disc, a first servo motor fixedly disposed at the lower end of the receiving bin and drivenly connected to the first solid agent spreading disc, a liquid mixing bin at the lower end of the vehicle body, a stirring rod rotatably disposed inside the liquid mixing bin and drivenly connected to the feeding rod via a belt, the second servo motor being started to drive the stirring rod to rotate and stir, mixing the liquid evenly, and simultaneously driving the feeding rod to rotate via the belt to prevent the solid de-icing agent at the bottom of the storage bin from accumulating and obstructing the discharge, a second servo motor fixedly disposed on one side of the liquid mixing bin and drivenly connected to the stirring rod, and a liquid agent spraying mechanism disposed on one side of the vehicle body.

[0046] For an example, please refer to... Figure 1 , 2 3, 4, and 5: The edges of the first and second solid agent spreading discs are equipped with meshing teeth, and the first and second solid agent spreading discs are connected by meshing teeth. Solid de-icing agent falls into the spreading grooves on the upper surface of the first and second solid agent spreading discs in the hopper. The first servo motor is started to drive the first solid agent spreading disc to rotate. At the same time, the first solid agent spreading disc drives the second solid agent spreading disc to rotate through the meshing teeth, thus spreading the solid de-icing agent.

[0047] For an example, please refer to... Figure 1 , 2 3, 4 and 5, the upper surface edge of the first solid agent dispensing plate 3 and the second solid agent dispensing plate 26 is provided with a number of dispensing grooves 27 arranged in a ring array, and the edges of the dispensing grooves 27 are open.

[0048] For an example, please refer to... Figure 1 , 2 3, 4, and 5, the liquid agent spraying mechanism includes a spray head, a sliding sleeve, a lead screw, a hollow tube, a first nut, a connecting rod, a valve plate, a tap, a water pump, a mounting base, a rotating shaft, a mounting plate, a second nut, a third servo motor, and a sliding groove.

[0049] For an example, please refer to... Figure 1 , 2 3, 4 and 5, the mounting base surface is provided with several hollow tubes, and a spray head is fixed at one end of each hollow tube.

[0050] For an example, please refer to... Figure 1 , 23, 4 and 5, the hollow tube surface is provided with a sliding sleeve, the lower end of the sliding sleeve is rotatably connected to a mounting plate through a rotating shaft, and the lower end of the mounting plate is fixedly provided with a second nut.

[0051] For an example, please refer to... Figure 1 , 2 3, 4, and 5 are connected to the lead screw and the third servo motor. The threads on both sides of the lead screw are set in opposite directions. The second nut and the first nut are threaded to both sides of the lead screw. The thread density between the lead screw and the second nut is less than that between the lead screw and the first nut. When the third servo motor is started, it drives the lead screw to rotate. Since the thread density between the lead screw and the second nut is less than that between the lead screw and the first nut, the movement speed of the second nut is greater than that of the first nut. Also, since the threads on both sides of the lead screw are set in opposite directions, the movement directions of the second nut and the first nut are opposite. When the second nut moves towards the middle, it drives the mounting plate to move. At this time, the sliding sleeve moves on the surface of the hollow tube, causing the hollow tube to rotate and unfold in a fan shape. At this time, the sliding sleeve will also rotate on its own axis to follow the rotation, increasing the spraying range. At the same time, the first nut drives the valve plate to open the outlet inside the sliding groove through the connecting rod, increasing the drainage volume. Conversely, if it is operated in the opposite direction, the spraying range and drainage volume will be reduced.

[0052] For an example, please refer to... Figure 1 , 2 3, 4 and 5, the first nut is fixedly connected to the valve plate through the connecting rod, and the valve plate is slidably connected inside the sliding groove.

[0053] For an example, please refer to... Figure 1 , 2 3, 4, and 5: The upper outlet of the sliding trough is connected to the tap via a pipe. The tap is connected to the hollow pipe via several hoses. The water inlet of the sliding trough is connected to the water pump via a pipe. The water pump is connected to the liquid mixing chamber via a pipe. The water pump draws the liquid de-icing agent into the sliding trough and then into the tap, which then flows through the hoses into multiple hollow pipes and is sprayed out through the spray head.

[0054] Working principle: When using solid de-icing agent, pour it into the storage hopper and liquid de-icing agent into the liquid mixing hopper. Start the second servo motor to drive the stirring rod to rotate and mix the liquid evenly. Simultaneously, the belt drives the feeding rod to rotate, preventing solid de-icing agent from accumulating at the bottom of the storage hopper and obstructing the flow of the agent. The solid de-icing agent falls into the feeding grooves on the upper surface of the first and second solid agent feeding discs in the hopper. Start the first servo motor to drive the first solid agent feeding disc to rotate, and simultaneously, the first solid agent feeding disc drives the second solid agent feeding disc to rotate through meshing teeth, spraying the solid de-icing agent out. Adjusting the rotation speed adjusts the spray range. The water pump draws the liquid de-icing agent into the sliding trough, then into the tap, and then through the hose... Do not insert multiple hollow tubes. Spraying through the spray head can start the third servo motor to drive the lead screw to rotate. Since the thread density of the lead screw surface connected to the second nut is less than that of the lead screw surface connected to the first nut, the moving speed of the second nut is greater than that of the first nut. Also, since the thread directions on both sides of the lead screw are set in opposite directions, the moving directions of the second nut and the first nut are opposite. When the second nut moves towards the middle, it drives the mounting plate to move. At this time, the sliding sleeve moves on the surface of the hollow tube, driving the hollow tube to rotate and unfold in a fan shape. At this time, the sliding sleeve will also rotate on its own axis to follow the rotation, increasing the spray range. At the same time, the first nut drives the valve plate to open the outlet inside the sliding groove through the connecting rod, increasing the drainage volume. Conversely, if it is operated in the opposite direction, the spray range and drainage volume will be reduced.
