Description

Technical Field

[0001] The invention belongs to the technical field of road snow removal, in particular to a highway snow melting agent spreader and a use method thereof. Background Art

[0002] With the continuous development of highway transportation, the impact of severe winter weather on road safety is becoming increasingly serious. Especially in snowy weather, snow accumulation and ice formation seriously affect the traffic capacity and safety of highways. In order to ensure the trafficability of highways in snowy days, timely and effectively remove snow and prevent ice formation, the spreading of snow melting agents has become one of the important countermeasures.

[0003] A patent of Chinese patent application CN115142377A discloses a snowmelt spreader for highways, and the key points of its technical solution are: it includes a machine body, the outside of the machine body is fixedly sleeved with a mounting sleeve, the bottom end of the machine body is fixedly connected with an extraction pipe, an extractor is arranged below the extraction pipe, a spreading tray is arranged below the extractor, a support rod is fixedly connected between the spreading tray and the machine body, a driving motor is fixedly connected at the middle position of the top of the machine body, and both sides of the top of the machine body are fixedly connected with a feed port. The snowmelt spreader for highways extracts the snowmelt through the extraction pipe, and the snowmelt inside the spreading tray is sprayed out from the first spray port and the second spray port respectively by pressure. The first spray port increases the range of snowmelt spreading, and the second spray port is evenly distributed, which improves the uniformity of snowmelt spreading.

[0004] However, the above technology often has the following defects: when in use, the de-icing agent can only be spread on the snow surface of the road. Although the spreading uniformity of the surface snow is improved, the weather in the high-altitude and cold regions is extreme, the snowfall is heavy, and the thickness of the snow formed by one snowfall is deep. Therefore, it is far from enough to just spread the de-icing agent on the surface of the snow. The de-icing agent is difficult to penetrate into the snow, resulting in low snow melting efficiency.

[0005] To this end, the present invention provides a highway snow melting agent spreader and a method for using the same. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0008] Preferably, the surface of the shaft tube is fixedly connected to limit plates at both sides of the rolling wheel.

[0009] Preferably, an annular screen is fixedly connected inside the rolling wheel; the middle of the screen is bent toward the edge of the rolling wheel; and a group of weight beads are placed on the surface of one side of the screen close to the shaft tube.

[0010] Preferably, a group of anti-skid pads are evenly distributed on the outer side of the rolling wheel.

[0011] Preferably, a group of sleeves are evenly distributed on the side edge of the rolling wheel; a core rod is arranged inside the sleeve; and one end of the core rod extending outside the sleeve is designed to be spike-shaped.

[0012] Preferably, a group of protrusions are evenly distributed on the inner side of the rolling wheel; the sleeve, anti-skid pad and protrusion correspond to each other; the anti-skid pad is designed as an elastic hollow structure; a group of elastic parts are evenly distributed inside the anti-skid pad; a slide groove is opened inside the protrusion; a pair of guide blocks are connected in a sliding and sealing manner inside the slide groove; a spring is fixedly connected between the guide blocks; the middle part of the slide groove and the anti-skid pad are connected to each other through a connecting pipe; the core rod is slidably connected to the inside of the sleeve; a connecting rod is fixedly connected between the core rod and the guide block.

[0013] Preferably, a pressure relief hole is opened inside the guide block; a pressure relief valve is arranged inside the pressure relief hole; a limit filter is fixedly connected to the opening of the slide groove, and a connecting rod passes through the limit filter and is slidably connected thereto; the core rod is designed to be a hollow structure, and a group of through holes are evenly distributed on its surface.

[0014] Preferably, an air inlet is provided on the surface of the anti-slip pad; a one-way valve is provided inside the air inlet.

[0015] A method for using a highway deicing agent spreader, which is applicable to the above-mentioned highway deicing agent spreader, comprises the following steps: S1: Add snow melting agent to the storage tank in advance and install the load-bearing beam at the rear of the working vehicle; S2: The vehicle drives the load-bearing beam to move, so that multiple rolling wheels roll on the road surface. The rolling wheels can roll the snow into depressions, leaving a group of ruts on the snow surface; S3: The delivery pipe is opened by controlling the electromagnetic valve, and the de-icing agent in the storage tank enters the inside of the rolling wheel through the delivery pipe, the shaft pipe and the discharge trough, and finally falls outward along the spreading hole and falls into the indentation of the rolling wheel, sinking the de-icing agent to the depth of the snow accumulation; S4: When the anti-slip pad rotates to the bottom, it is squeezed, and the air inside it enters the slide groove and pushes a pair of guide blocks to move to both sides, driving the core rod to slide outward inside the sleeve, so that the core rod is inserted into the snow; S5: When the guide block moves to the limit filter, it will be blocked. When the air pressure inside the chute reaches the threshold of the pressure release valve, the high-pressure air can be ejected to the limit filter through the pressure relief hole, blowing the snow melting agent between the two sides of the convex block and the inner wall of the rolling wheel into the core rod and into the snow through the through hole. S6: When the casing and the core rod rotate upward, the surrounding snow can be moved and lifted, changing the original accumulation state of the snow. The lifted snow is conducive to falling into the indentation of the rolling wheel, covering the spread snow-melting agent, making it easier for the snow-melting agent to fully contact with the snow.

[0016] The beneficial effects of the present invention are as follows: 1. The highway deicing agent spreader and the use method thereof described in the present invention drive the device to move by a vehicle, so that a plurality of rolling wheels roll on the road surface, and the delivery pipe is controlled to open by an electromagnetic valve and the opening of the delivery pipe is adjusted according to the movement speed of the vehicle. The deicing agent in the storage box enters the hollow structure of the rolling wheel through the delivery pipe, the shaft pipe and the discharge chute, and finally falls to the surface of the snow along the spreading holes on the surface of the rolling wheel. In this process, the rolling wheel can roll the snow into a depression, leaving a group of ruts on the surface of the snow, so that the fallen deicing agent can just enter the ruts, thereby sinking the deicing agent to the deep of the snow, allowing the snow melting effect to diffuse from the ruts to the surroundings, thereby increasing the range of action of the deicing agent on the snow.

[0017] 2. The highway de-icing agent spreader and the use method thereof described in the present invention filter the de-icing agent entering the rolling wheel by setting a screen, and de-icing agent with normal particle size can smoothly pass through the screen to reach the bottom of the rolling wheel and be discharged through the spreading hole, while the agglomerated de-icing agent will be blocked on the surface of the screen. Under the rolling action of the rolling wheel, the block de-icing agent can continuously move and shake on the surface of the screen, which is conducive to its gradual fragmentation and dispersion. Moreover, by setting counterweight beads, the counterweight beads can roll on the surface of the screen, thereby continuously squeezing and crushing the block de-icing agent, thereby improving the fragmentation efficiency of the de-icing agent, until it can smoothly pass through the screen.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 7 As shown, a highway snow melting agent spreader according to the present invention comprises a load-bearing beam 1, a rolling wheel 2 and a supporting and conveying assembly; A storage box 3 is fixedly connected to the upper side of the load-bearing beam 1; a deicing agent is added inside the storage box 3, and the deicing agent can be commonly used sodium chloride, calcium chloride, magnesium chloride, urea, etc.; The rolling wheel 2 is provided with a group and is located at the bottom of the load-bearing beam 1; the rolling wheel 2 is designed as a hollow structure; the surface of the rolling wheel 2 is evenly distributed with a group of spreading holes 4; The supporting and conveying assembly is used to support the rolling wheel 2 for rotation and convey the snow melting agent in the storage box 3 to the inside of the rolling wheel 2; the supporting and conveying assembly includes a set of conveying pipes 5 and an axle pipe 6; the upper end of the conveying pipe 5 is fixedly connected to the storage box 3 and communicated with each other; the switch of the conveying pipe 5 is controlled by a solenoid valve 7; The conveying pipe 5 is designed to be in a "Y" shape; the conveying pipe 5 and the shaft tube 6 are staggered and interconnected; the conveying pipe 5 is respectively located between adjacent rolling wheels 2; the shaft tubes 6 respectively penetrate the rolling wheels 2 and are rotatably connected thereto; the interior of the rolling wheel 2 and the shaft tube 6 are interconnected through a discharge trough 8.

[0023] The de-icing agent spreading device in the prior art can only spread the de-icing agent on the snow surface of the road when in use. Although it improves the spreading uniformity of the surface snow, the weather in high-altitude and cold regions is extreme, the snowfall is heavy, and the thickness of the snow formed by one snowfall is deep. Therefore, it is far from enough to just spread the de-icing agent on the surface of the snow. The de-icing agent is difficult to penetrate into the snow, resulting in low snow melting efficiency.

[0024] When in use, the present invention uses bolts or pins to install the load-bearing beam 1 on the rear of the working vehicle, and the vehicle drives the device to move, so that multiple rolling wheels 2 roll on the road surface. The electromagnetic valve 7 is used to control the delivery pipe 5 to open and adjust the opening of the delivery pipe 5 according to the vehicle movement speed. The snow melting agent in the storage box 3 enters the hollow structure of the rolling wheel 2 through the delivery pipe 5, the shaft tube 6 and the discharge chute 8, and finally falls to the surface of the snow along the spreading hole 4 on the surface of the rolling wheel 2. In this process, the rolling wheel 2 can roll the snow into a depression, leaving a group of rutting indentations on the surface of the snow, so that the fallen snow melting agent can just enter the indentations, thereby sinking the snow melting agent to the deep of the snow, allowing the snow melting effect to diffuse from the indentations to the surroundings, thereby increasing the range of action of the snow melting agent on the snow.

[0025] As a preferred embodiment of the present invention, the surface of the shaft tube 6 is fixedly connected with limit plates 9 at both sides of the rolling wheel 2. The limit plates 9 are used to limit the axial position between the shaft tube 6 and the rolling wheel 2 to prevent the rolling wheel 2 from shifting or running off during rotation.

[0026] As a preferred embodiment of the present invention, a ring-shaped screen 10 is fixedly connected inside the rolling wheel 2; the middle part of the screen 10 is bent toward the edge of the rolling wheel 2; and a group of counterweight beads 11 are placed on the surface of one side of the screen 10 close to the shaft tube 6. Since the de-icing agent inside the storage box 3 may clump due to moisture and other reasons during storage, which will cause the de-icing agent to be unevenly spread, the present invention sets a screen 10 to filter the de-icing agent entering the rolling wheel 2. De-icing agent with normal particle size can smoothly pass through the screen 10 to reach the bottom of the rolling wheel 2 and be discharged through the spreading holes 4, while the agglomerated de-icing agent will be blocked on the surface of the screen 10. Under the rolling action of the rolling wheel 2, the block de-icing agent can continuously move and shake on the surface of the screen 10, which is conducive to its gradual fragmentation and dispersion. In addition, by setting the counterweight beads 11, the counterweight beads 11 can roll on the surface of the screen 10, thereby continuously squeezing and crushing the block de-icing agent, thereby improving the fragmentation efficiency of the de-icing agent until it can smoothly pass through the screen 10.

[0027] As a preferred embodiment of the present invention, a group of anti-skid pads 12 are evenly distributed on the outer side of the rolling wheel 2, and the anti-skid pads 12 protrude from the surface of the rolling wheel 2. By providing the anti-skid pads 12, the grip of the rolling wheel 2 can be improved to ensure that it can rotate smoothly.

[0028] As a preferred embodiment of the present invention, a group of sleeves 13 are evenly distributed on the side edge of the rolling wheel 2; a core rod 14 is arranged inside the sleeve 13; and one end of the core rod 14 extending outside the sleeve 13 is designed to be spike-shaped. During the rotation of the rolling wheel 2, when the sleeve 13 and the core rod 14 rotate to the bottom, the snow on both sides of the rolling wheel 2 can be further squeezed by the sleeve 13 and the core rod 14, and then when the sleeve 13 and the core rod 14 rotate upward with the rolling wheel 2, the surrounding snow can be moved and lifted, changing the original accumulation state of snowfall, improving the effect of the snow-melting agent, and the sleeve 13 and the core rod 14 lift the snow on both sides of the indentation of the rolling wheel 2, which is conducive to making the snow fall into the concave indentation, thereby covering the spread snow-melting agent, so that the snow-melting agent can fully contact with the snow and play a role.

[0029] A group of protrusions 15 are evenly distributed on the inner side of the rolling wheel 2; the sleeve 13, the anti-skid pad 12 and the protrusion 15 correspond to each other; the anti-skid pad 12 is designed as an elastic hollow structure; a group of elastic members 16 are evenly distributed inside the anti-skid pad 12; a slide groove 17 is opened inside the protrusion 15; a pair of guide blocks 18 are connected in a sliding and sealing manner inside the slide groove 17; a spring 19 is fixedly connected between the guide blocks 18; the middle part of the slide groove 17 and the anti-skid pad 12 are connected to each other through a connecting pipe 20; the core rod 14 is slidably connected to the inside of the sleeve 13; a connecting rod 21 is fixedly connected between the core rod 14 and the guide block 18. When the anti-skid pad 12 rotates to the bottom, it is squeezed by the road surface and the snow, causing the volume of the anti-skid pad 12 to shrink, and the air inside it is introduced into the slide groove 17 through the connecting pipe 20, and pushes a pair of guide blocks 18 to move to both sides. The guide blocks 18 and the connecting rod 21 drive the core rod 14 to slide outward inside the sleeve 13, and then the core rod 14 is inserted into the snow. When it rotates upward with the rolling wheel 2, the core rod 14 can be used to further lift the surrounding snow, thereby improving the efficiency of moving the snow.

[0030] A pressure relief hole 22 is provided inside the guide block 18; a pressure relief valve is provided inside the pressure relief hole 22; a limit filter 23 is fixedly connected to the opening of the slide groove 17, and the connecting rod 21 passes through the limit filter 23 and is slidably connected thereto; the core rod 14 is designed as a hollow structure, and a group of through holes 24 are evenly distributed on its surface.

[0031] An air inlet 25 is disposed on the surface of the anti-slip pad 12 ; a one-way valve is disposed inside the air inlet 25 .

[0032] The snow melting agent entering the rolling wheel 2 will accumulate at the bottom of the rolling wheel 2 under the action of gravity. A part of it is located between the adjacent protrusions 15 and discharged outwardly along the spreading holes 4, and the other part is located between the two sides of the protrusions 15 and the inner wall of the rolling wheel 2. When the anti-skid pad 12 moves to the bottom and is squeezed, the air enters the chute 17 and drives the guide block 18 to move to both sides, causing the core rod 14 to extend outward and insert into the snow. When the guide block 18 moves to the limit filter 23, it will be blocked. At this time, the through holes 24 are all exposed to the outside. As the internal gas of the anti-skid pad 12 continues to enter the chute 17, the air pressure in the chute 17 will continue to increase. When the pressure value reaches the pressure relief threshold of the pressure relief valve, the pressure relief valve will automatically open. The snow-melting agent is started, and the high-pressure air in the slide groove 17 overflows to the limit filter screen 23 through the pressure relief hole 22, and then blows the snow-melting agent between the two sides of the protrusion 15 and the inner wall of the rolling wheel 2 into the core rod 14, and blows it into the snow through the through hole 24 on the surface of the core rod 14, so that the core rod 14 is first inserted into the snow and then the snow-melting agent is released into the snow, further improving the distribution depth and uniformity of the snow-melting agent in the snow, expanding the scope of action of the snow-melting agent, and accelerating the melting process of the snow. When the anti-skid pad 12 rotates upward with the rolling wheel 2 and is no longer squeezed, the spring 19 drives the guide block 18 and the core rod 14 to return to their original position, and the elastic member 16 drives the anti-skid pad 12 to expand and recover, and the anti-skid pad 12 re-inhales air through the air inlet 25.

[0033] like Figure 8 As shown, the method for using a highway de-icing agent spreader according to the present invention is applicable to the above-mentioned highway de-icing agent spreader, and comprises the following steps: S1: Add snow melting agent to the storage box 3 in advance, and install the load-bearing beam 1 at the rear of the working vehicle; S2: The vehicle drives the load-bearing beam 1 to move, so that the plurality of rolling wheels 2 roll on the road surface. The rolling wheels 2 can roll the snow to form depressions, leaving a group of ruts on the snow surface; S3: The delivery pipe 5 is opened by controlling the electromagnetic valve 7, and the deicing agent in the storage box 3 enters the interior of the rolling wheel 2 through the delivery pipe 5, the shaft pipe 6 and the discharge trough 8, and finally falls outward along the spreading hole 4 and falls into the indentation of the rolling wheel 2, sinking the deicing agent to the depth of the snow accumulation; S4: When the anti-slip pad 12 rotates to the bottom, it is squeezed, and the air inside it enters the slide groove 17 and pushes the pair of guide blocks 18 to move to both sides, driving the core rod 14 to slide outward inside the sleeve 13, so that the core rod 14 is inserted into the snow; S5: When the guide block 18 moves to the limit filter 23, it will be blocked. When the air pressure inside the chute 17 reaches the threshold of the pressure release valve, the high-pressure air can be ejected to the limit filter 23 through the pressure relief hole 22, and the snow melting agent between the two sides of the protrusion 15 and the inner wall of the rolling wheel 2 is blown into the core rod 14, and then blown into the snow through the through hole 24; S6: When the sleeve 13 and the core rod 14 rotate upward, the surrounding snow can be moved and lifted up, changing the original accumulation state of the snow. The lifted snow is conducive to falling into the indentation of the rolling wheel 2, covering the spread snow-melting agent, so that the snow-melting agent can fully contact with the snow.
