Description

Technical Field

[0001] The present invention relates to the technical field of road snow removal, and in particular to a self-cleaning snow removal device and a method for using the same. Background Art

[0002] During winter snowfall in northern China, a thick layer of snow often accumulates on the road surface. If not removed in time, a layer of ice will form on the road surface, seriously affecting road traffic safety and causing traffic accidents. Existing methods of road snow removal mainly rely on manual snow removal and snowplows. Manual snow removal is inefficient and ineffective. When snowplows are used for snow removal, they often use the snow roller brush in front of the snowplow to sweep the snow on the road surface. However, this method of snow removal has the following problems:

[0003] (1) When the roller brush is working, the ice and snow adhered to the steel brush cannot be removed, which will greatly affect the snow removal effect;

[0004] (2) After the roller brush has been working for a period of time, it is impossible to determine the degree of wear of the steel brush and whether the steel brush can continue to remove snow. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides a self-cleaning snow removal device and a method for using the same, which solves the problems of inconvenience in removing ice and snow stuck on the existing integrated roller brush and difficulty in judging the degree of wear of the integrated roller brush.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a self-cleaning snow removal device, comprising an outer box, one side of the outer box is rotatably connected to a snow guard, and one side of the snow guard is equipped with a snow sweeping assembly, which is characterized in that: the snow sweeping assembly comprises two baffles mounted on the bottom of the snow guard, an integrated roller brush is rotatably connected between the two baffles, one side of one baffle is fixedly connected to a motor for driving the integrated roller brush to rotate, and two judgment assemblies are installed on the other side of the outer box, the judgment assembly comprises an outer cylinder fixedly connected to the outer box, the interior of the outer cylinder is provided with a longitudinal rod at one end movably extending to the outside thereof, the bottom of the longitudinal rod is fixedly connected to a roller, the top of the outer cylinder is fixedly connected to a pressure alarm, and a spring is fixedly connected between the longitudinal rod and the pressure alarm, and a snow scraping assembly is installed at the bottom of the snow guard, and the snow scraping assembly comprises a cylinder fixedly connected to the snow guard, and one side of the cylinder is fixedly connected to a useful The adjusting assembly is installed between the outer box and the snow-clearing assembly, and the adjusting assembly includes a bracket fixedly connected to one side of the outer box, a bending rod is installed on the rotating rod of the bracket, one side of the bending rod is fixedly connected to the second hydraulic telescopic cylinder and the third hydraulic telescopic cylinder, the second hydraulic telescopic cylinder is connected to the tilting rod, and the first hydraulic telescopic cylinder is installed inside the cylinder, and the output end of the first hydraulic telescopic cylinder is movably extended to the outside of the cylinder, and the output end of the first hydraulic telescopic cylinder is fixedly connected to the sliding rod, and a plurality of snow scraping blades are fixedly connected to the top of the sliding rod. The cross-section of the snow scraping blade is semicircular, and the diameter of the snow scraping blade is the same as the diameter of the integrated roller brush. Six semicircular recesses are provided on the bottom of the snow scraping blade, and the top of the snow guard is fixedly connected with the tilting rod, which is rotatably connected to the second hydraulic telescopic cylinder. A third hydraulic telescopic cylinder is installed on one side of the outer box, and the third hydraulic telescopic cylinder is rotatably connected to the bending rod.

[0007] A method for using a self-cleaning snow removal device is implemented using the self-cleaning snow removal device described above, comprising the following steps:

[0008] S1. When snow accumulates on the road and affects driving safety, the self-cleaning snow removal device is activated and the device performs snow removal operations at a rated speed of 200r / min to clear the snow on the road;

[0009] S2. After the snow removal device has been working for a period of time, ice and snow will stick to the integrated roller brush, and the snow removal function of the device will decrease. The snow on the road after clearing will become thicker, and the snow accumulation will cause the pressure alarm to sound an alarm. The specific steps are as follows:

[0010] S2-1): After the snow on the road is cleared, the roller drives the connected longitudinal rod to compress the spring with a spring constant K of 0.1N / mm, causing the spring to deform, and the deformation is recorded as X;

[0011] S2-2): According to Hooke's law: F=KX, calculate the pressure value F of the spring on the pressure alarm;

[0012] S2-3): When the snow thickness exceeds 1mm, it is not suitable for driving. When the snow thickness H=1mm, the deformation X=1mm is generated and the pressure value of the pressure alarm F=0.1N;

[0013] S2-4): The pressure alarm determines whether to sound an alarm based on the pressure value F:

[0014] ① If F < 0.1N, it is judged that the cleared road surface H < 1mm, the pressure alarm does not sound an alarm, and the device continues to clear the snow on the road;

[0015] ② If F>0.1N, it is judged that the cleared road surface H>1mm, the snow thickness on the road exceeds the allowable range, and the pressure alarm sounds an alarm;

[0016] S3: After the snow removal device issues an alarm, the snow scraping assembly is activated to scrape off the ice and snow adhered to the integrated roller brush to restore the snow removal function of the device. The specific steps are as follows:

[0017] When the pressure alarm sounds, the snow scraper assembly starts working. The first hydraulic telescopic cylinder in the snow scraper assembly drives the snow scraper to make reciprocating motion. When the snow scraper fully contacts and rubs against the integrated roller brush, the ice and snow stuck on the integrated roller brush can be removed, so that the snow removal function of the snow removal device is restored. The thickness of snow on the road decreases, and the pressure value F of the pressure alarm decreases. When F < 0.1N, the pressure alarm stops sounding the alarm.

[0018] S4. After the snow scraping assembly is activated to scrape off the ice and snow adhered to the integrated roller brush, the snow removal function of the device is not restored. It is determined that the integrated roller brush is worn. The specific determination steps are as follows:

[0019] S4-1): Set the time t for the snow scraper to clean the snow removal device:

[0020] The rotation period f of the integrated roller brush is 0.3s / rad, and the reciprocating period f of the snow scraper is 10s / time. The greatest common divisor of the two times is 30s. That is, when the snow scraper's snow removal time t is 30s, the snow scraper can clean the entire integrated roller brush.

[0021] S4-2): The wear condition of the integrated roller brush (32) is judged by the relationship between the time T when the pressure alarm sounds an alarm and 30 seconds:

[0022] ① If T < 30s, it is a short alarm, judging that the snow removal device has poor snow removal performance due to ice and snow adhering to the integrated roller brush. After starting the snow scraper assembly, the snow removal function of the snow removal device is restored, and there is no need to replace the integrated roller brush;

[0023] ② If T>30s, it is a continuous alarm, that is, after the snow scraper scrapes off the ice and snow on the integrated roller brush, the snow removal device cannot resume snow removal function, and it is determined that the integrated roller brush is worn and needs to be replaced;

[0024] S5. When the integrated roller brush of the snow removal device is worn, replace the integrated roller brush. After replacement, the device can continue to remove snow. The specific replacement steps are as follows:

[0025] When replacing the integrated roller brush, start the adjustment assembly, and the second and third hydraulic telescopic cylinders of the adjustment assembly will retract at the same time, causing the snow guard and the bending rod to rotate clockwise, driving the snow-clearing assembly under the snow guard to rise. At this time, replace the integrated roller brush.

[0026] Preferably, three mounting plates are fixedly connected to one side of the outer box, the third hydraulic telescopic cylinder is mounted on the mounting plate, and a plurality of circular holes penetrating the mounting plate are provided on the top of the mounting plate.

[0027] Preferably, the snow-clearing assembly is rotatably connected to the snow guard, and telescopic tubes are rotatably connected between both sides of the snow-clearing assembly and the outer box.

[0028] Compared with the prior art, the present invention provides a self-cleaning snow removal device with the following beneficial effects:

[0029] 1. The snow scraping component is set up to clean the ice and snow stuck on the snow removal roller brush, preventing the ice and snow from adhering to the roller brush and reducing the friction between the roller brush and the snow on the ground, thereby reducing the roller brush's effect of clearing the snow on the ground. At the same time, the component does not need to stop the snow removal roller brush before scraping and removing snow. This setting makes the road snow removal efficiency higher.

[0030] 2. A detection component is set up to determine whether the roller's action on the pressure alarm is brief or continuous, with a 30-second action time limit. If the action is brief, it can be determined that the roller brush is sticking to ice and snow, resulting in poor snow removal performance. If the action is continuous, it can be determined that the roller brush is worn, resulting in poor snow removal performance. Based on the judgment results, the wear of the snow removal component can be promptly detected and replaced when wear affects snow removal performance. Compared with existing snow removal rollers that rely on staff to observe the wear condition, this judgment method simplifies the difficulty of determining whether the snow removal component needs to be replaced.

[0031] 3. Through the setting of the adjustment component, when the snow-clearing component needs to be replaced, the snow-clearing component under the snow guard is driven to be lifted, thereby realizing mechanical replacement. Compared with traditional manual replacement, the setting of this component can not only replace the snow-clearing component faster, but also avoid the consumption of human resources.

[0032] 4. By quantifying the rotation speed of the integrated roller brush, the extension and retraction speed of the first hydraulic telescopic cylinder, the alarm pressure value of the pressure alarm and the spring coefficient of the spring, the shortest continuous alarm time of the pressure alarm when the integrated roller brush needs to be replaced is clarified, making it more convenient, timely and accurate to replace the integrated roller brush, thereby avoiding the impact of snow on the road after cleaning on driving.

DETAILED DESCRIPTION

[0041] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0042] A self-cleaning snow removal device is installed at the front end of the road snowplow. When clearing snow, the roller brush rotates and rubs against the snow on the ground to sweep away the snow on the ground. Since the roller brush is in contact with the snow for a long time, a layer of snow is easily attached to its surface. The snow accumulated on the surface of the roller brush will reduce the friction between the roller brush and the snow on the ground, causing the roller brush to slide over the surface of the snow on the ground and unable to sweep away the snow. This reduces the effect of the roller brush in clearing the snow on the road, so that a layer of snow still remains on the ground after clearing. In order to always maintain the cleaning effect of the roller brush on the snow, the present invention proposes the following embodiments.

[0043] Example 1

[0044] Reference Figure 1-Figure 3 The present invention is a specific embodiment of the present invention, which prevents the snow from adhering to the roller brush by clearing the snow on the surface of the roller brush, thereby maintaining the roller brush's effect of clearing the snow on the ground. Specifically, it is a self-cleaning snow removal device, which consists of an outer box 1 installed at the front end of a road snowplow, a snow guard 2 rotatably connected to the outer box 1, and a snowplow assembly 3 installed on one side of the snow guard 2. A snow scraper assembly 5 for scraping off the snow adhered to the surface of the snowplow assembly 3 is installed at the bottom of the snow guard 2. The outer box 1 is installed at the front end of the road snowplow. When it is necessary to sweep snow on the road, the road snowplow drives the outer box 1 and the snowplow assembly 3 forward, and the snowplow assembly 3 sweeps the snow on the ground. When the snow is being cleared, When snow adheres to the surface of assembly 3, causing the snow removal efficiency to decline, the snow scraper assembly 5 is activated. Driven by a first hydraulic telescopic cylinder 52, the snow scraper assembly 5 reciprocates along the length of the snow removal assembly 3 at a rate of six reciprocating cycles per minute. The snow scraper assembly 5 is provided with multiple snow scraping blades 54 at its base, each with six semicircular recesses. These recesses allow for sufficient contact and friction with the integrated roller brush of the snow removal assembly 3, scraping off the snow adhered to the integrated roller brush of the snow removal assembly 3. Once the snow adhered to the snow removal assembly 3 is cleared, the snow removal efficiency returns to normal, and the snow removal process can resume. This design facilitates the removal of ice and snow adhering to the integrated roller brush, achieving self-cleaning. This prevents ice and snow from adhering to the steel brush, reducing friction between the brush and the snow on the ground, thereby reducing the snow removal efficiency of the integrated roller brush, allowing the integrated roller brush to continue operating normally without requiring the snow removal device to stop.

[0045] In order to remove the snow attached to the roller brush, this embodiment adopts a snow scraper assembly 5 with an improved structure. The specific implementation method is as follows: the snow scraper assembly 5 consists of a cylinder 51 fixedly connected to the snow guard 2, and a first hydraulic telescopic cylinder 52 installed in the cylinder 51. The output end of the first hydraulic telescopic cylinder 52 is movably extended to the outside of the cylinder 51. The output end of the first hydraulic telescopic cylinder 52 is fixedly connected to a slide rod 53. The top of the slide rod 53 is fixedly connected to multiple snow scrapers 54. One side of the cylinder 51 is fixedly connected to a slide rod for supporting the slide. The support plate 55 of the rod 53, when it is necessary to clean the snow attached to the snow-clearing assembly 3, the first hydraulic telescopic cylinder 52 drives the slide rod 53 and the snow scraper 54 to move, the slide rod 53 is parallel to the first hydraulic telescopic cylinder 52, and the snow scraper 54 is perpendicular to the slide rod 53. When the snow scraper 54 is driven, the semicircular depression on the snow scraper 54 contacts and rubs with the integrated roller brush 32 on the snow-clearing assembly 3, scraping off the snow attached to the surface of the snow-clearing assembly 3, preventing the snow from adhering to the surface of the snow-clearing assembly 3, thereby reducing its effect of clearing the snow on the road surface.

[0046] In order to complete the snow-clearing process, this embodiment improves the snow-clearing assembly 3. The specific implementation method is as follows: the snow-clearing assembly 3 is composed of two baffles 31 installed at the bottom of the snow guard 2, and an integrated roller brush 32 is rotatably connected between the two baffles 31. One side of one baffle 31 is fixedly connected to a motor 33 for driving the integrated roller brush 32 to rotate. During the snow-clearing process, the motor 33 drives the integrated roller brush 32 to rotate, and the integrated roller brush 32 sweeps the snow on the ground during the rotation.

[0047] In order to improve the ability of the snow scraper 54 to remove snow attached to the snow-clearing assembly 3, this embodiment improves the structure of the snow scraper 54 so that it can better fit the snow-clearing assembly 3 to scrape snow. The specific implementation method is as follows: the cross-section of the snow scraper 54 is semicircular, and the diameter of the snow scraper 54 is the same as the diameter of the integrated roller brush 32. Six semicircular recesses are provided at the bottom of the snow scraper 54. The diameter of the recesses is moderate and can fully contact and fit with the integrated roller brush, and the semicircular recesses are evenly distributed at the bottom of the snow scraper 54. When the snow scraper 54 moves, the semicircular recesses at its bottom can better fit with the integrated roller brush 32 and prevent the steel brush on the integrated roller brush 32 from sliding to both sides. The integrated roller brush 32 always slides perpendicular to the snow scraper 54, which can enable the snow scraper 54 to contact the integrated roller brush 32 for a longer time and better scrape off the snow attached to the surface of the integrated roller brush 32.

[0048] Example 2

[0049] Although clearing the snow attached to the surface of the snow-clearing assembly 3 can ensure the snow-clearing effect of the snow-clearing assembly 3 on the road surface to a certain extent, as the snow-clearing assembly 3 is used for a long time, the friction time between the snow-clearing assembly 3 and the snow and road surface increases, the wear of the snow-clearing assembly 3 increases, and the snow-clearing effect of the snow-clearing assembly 3 on the road surface continues to decrease. It is difficult for the staff to judge the degree of wear of the snow-clearing assembly 3 by observation, and to judge whether the snow-clearing assembly 3 should be replaced based on this. In order to accurately understand the wear condition of the snow-clearing assembly 3 and facilitate timely replacement of the snow-clearing assembly 3, this embodiment adds a relevant detection component to judge the wear condition of the snow-clearing assembly 3 by measuring the thickness of the snow on the road after cleaning. Figures 1-4 , the specific implementation is as follows: two judgment components 4 are installed on one side of the outer box 1, and the judgment component 4 consists of an outer cylinder 41 fixedly connected to the outer box 1, and a roller 42 installed at the bottom of the outer cylinder 41. The top of the bracket of the roller 42 is provided with a longitudinal rod 43, one end of which is movably extended to the inside of the outer cylinder 41. The top of the outer cylinder 41 is fixedly connected with a pressure alarm 44, and a spring 45 is fixedly connected between the longitudinal rod 43 and the pressure alarm 44. In the process of the snowplow driving the snowplow component 3 to move and sweep snow, when the sweeping effect of the snowplow component 3 becomes poor, the snow on the road after sweeping is thicker, and the accumulated snow causes the roller 42 to lift upward, thereby pushing the longitudinal rod 43 upward to squeeze the spring 45, and the squeezing force of the spring 45 on the pressure alarm 44 increases, thereby causing the pressure alarm 44 to issue a warning;

[0050] At this time, we first consider the impact of the accumulated snow on the snow-clearing assembly 3 on the snow on the road, so we first start the snow scraping assembly 5 to scrape off the snow attached to the surface of the snow-clearing assembly 3. When the snow attached to the surface of the snow-clearing assembly 3 is scraped off, the snow on the road becomes thinner after the snow is cleared, the roller 42 is reset, and the pressure alarm 44 is no longer warning. At this time, it means that the snow-clearing assembly 3 can still normally clear the snow on the road, so the wear degree of the snow-clearing assembly 3 is low and does not need to be replaced. When the snow-clearing assembly 5 has been working for a period of time, the pressure alarm 44 continues to sound an alarm, which means that the snow-clearing assembly 3 is worn and needs to be replaced, and the roller 42 can be used to move up and down. The floating reflects the thickness of the snow after clearing, and the roller 42 has a short and continuous action on the pressure alarm 44. If it is a short action, it can be judged that the integrated roller brush 32 is adhered to ice and snow, resulting in a deterioration in the snow removal effect. If it is a continuous action, it can be judged that the snow removal effect of the integrated roller brush 32 is deteriorated due to wear. According to the result of the judgment, the wear of the snow-clearing component 3 is discovered in time, and the snow-clearing component 3 is replaced when the wear of the snow-clearing component 3 affects the snow-clearing effect. Compared with the existing snow-clearing roller brush that relies on staff to observe the wear condition, the difficulty of judging whether the snow-clearing component 3 needs to be replaced is reduced.

[0051] Due to the sensitivity of the pressure alarm 44, it may be difficult to issue an alarm in time when the wear of the integrated roller brush 32 affects the snow cleaning effect on the road. This embodiment quantifies the wear monitoring of the integrated roller brush 32, helping to issue an alarm in time when the residual snow after the road is cleaned will affect driving, so that the staff can replace the integrated roller brush 32 in time. When the snow thickness on the road exceeds 1mm, it is not suitable for driving, so 1mm is used as the standard. The specific implementation method is as follows:

[0052] (1) When the thickness of snow on the road after clearing is less than 1 mm, the roller 42 in contact with the snow drives the connected longitudinal rod 43 to rise to a height h of less than 1 mm, the deformation X of the spring 45 fixedly connected to the longitudinal rod 43 is less than 1 mm, and the spring constant K of the spring 45 is 0.1 N / mm. According to Hooke's law: F=KX, F=0.1×1, F=0.1N, the pressure value F of the spring 45 on the pressure alarm 44 is less than 0.1 N, the pressure alarm 44 does not sound an alarm, and the snow removal device clears the snow on the road at the rated power and speed, i.e., 200 revolutions per minute;

[0053] (2) When the thickness of snow on the road after cleaning exceeds 1mm, the roller 42 in contact with the snow drives the connected longitudinal rod 43 to lift up to a height h exceeding 1mm, the deformation X of the spring 45 fixedly connected to the longitudinal rod 43 exceeds 1mm, and the pressure value F of the spring 45 on the pressure alarm 44 exceeds 0.1N. The pressure alarm 44 sounds an alarm. At this time, the first hydraulic telescopic cylinder 52 of the snow scraping assembly 5 is started to reciprocate at a telescopic cycle of 6 times per minute, driving the snow scraping blade 54 to reciprocate. The snow scraping blade 54 fully contacts the integrated roller brush 32 and removes the ice and snow adhered to the integrated roller brush 32. The rotation cycle f of the integrated roller brush 32 is 0.3s / revolution, and the movement cycle f of the snow scraping blade 54 is 10s / time. The greatest common divisor of the two cycles is 30s, that is, when the action time t of the snow scraping blade 54 is 30s, the snow scraping blade 54 can clean the entire integrated roller brush 32. The pressure alarm 44 performs the judgment work in the following way:

[0054] Step 1: When the pressure alarm 44 sounds an alarm, the first hydraulic telescopic cylinder 52 is activated to drive the snow scraper 54 to start removing the ice and snow adhered to the integrated roller brush 32. The ice and snow adhered to the integrated roller brush 32 are removed, the snow removal effect of the roller brush is restored, and the thickness of the snow on the road is reduced. When the thickness of the snow on the road is less than 1 mm, the pressure value of the pressure alarm is less than 0.1 N, the pressure alarm 44 stops sounding the alarm, the first hydraulic telescopic cylinder 52 stops moving, and the time for the pressure alarm 44 to sound the alarm is less than 30 seconds, which is a short-term effect. It is determined that the snow removal effect of the integrated roller brush 32 has deteriorated due to the adhesion of ice and snow, and no replacement is required.

[0055] Step 2: The pressure alarm 44 continues to sound an alarm. If the alarm lasts for more than 30 seconds, it is considered to be in continuous operation. After the snow scraper 54 scrapes off the ice and snow on the integrated roller brush 32, the roller brush cannot restore the snow removal effect. It is determined that the integrated roller brush 32 is worn and needs to be replaced. At this time, the snow removal device stops the snow removal operation and replaces the roller brush.

[0056] By quantifying the rotational speed of the integrated roller brush 32, the extension and retraction speed of the first hydraulic telescopic cylinder 52, the alarm pressure value of the pressure alarm 44, and the spring constant of the spring 45, the minimum duration of continuous alarming of the pressure alarm 44 before the integrated roller brush 32 needs to be replaced is calculated. Furthermore, if residual snow on the road surface after cleaning impedes driving, an alarm is issued promptly, facilitating more timely and accurate replacement of the integrated roller brush 32, thereby preventing traffic from being affected by accumulated snow on the cleaned road surface.

[0057] Example 3

[0058] When the snow sweeping assembly 3 is seriously worn and needs to be replaced, since the snow sweeping assembly 3 needs to be in contact with the ground at a low height, it is more laborious to replace it. In order to better complete the replacement process of the snow sweeping assembly 3 and reduce the difficulty of replacing the snow sweeping assembly 3, this embodiment improves the way the snow sweeping assembly 3 is connected to the entire device. Figure 1-Figure 5 , the height of the snow-clearing assembly 3 is changed by adjusting the angle of the snow-clearing assembly 3. The specific implementation method is as follows: an adjustment assembly 6 is installed between the outer box 1 and the snow-clearing assembly 3. The adjustment assembly 6 consists of a bracket 61 installed on one side of the outer box 1, and a second hydraulic telescopic cylinder 62 installed on the bracket 61. A bending rod 63 is installed on the rotating rod of the bracket 61. The second hydraulic telescopic cylinder 62 is fixedly connected to the bending rod 63. A tilting rod 64 is fixedly connected to the top of the snow guard 2. The tilting rod 64 is rotatably connected to the second hydraulic telescopic cylinder 62. One side of the outer box 1 is installed A third hydraulic telescopic cylinder 65 is installed, which is rotatably connected to the bending rod 63. When the snow-clearing assembly 3 needs to be replaced, the second hydraulic telescopic cylinder 62 and the third hydraulic telescopic cylinder 65 are simultaneously contracted, causing the snow guard 2 and the bending rod 63 to rotate clockwise, driving the snow-clearing assembly 3 under the snow guard 2 to rise. At this time, after the height of the snow-clearing assembly 3 is raised, the snow-clearing assembly 3 can be replaced faster than traditional manual labor. After the snow-clearing assembly 3 is replaced, the second hydraulic telescopic cylinder 62 and the third hydraulic telescopic cylinder 65 drive the snow guard 2 and the snow-clearing assembly 3 back to the starting point.

[0059] In order to better install this product on a road snowplow, the present invention installs convenient installation components on the outer box 1 to help this product better connect with the road snowplow. The specific implementation method is: three mounting plates 7 are fixedly connected to one side of the outer box 1, and the third hydraulic telescopic cylinder 65 is installed on the mounting plate 7. The mounting plate 7 has two holes on the left and right sides symmetrically arranged, and a hole in the middle, which is installed on the snowplow. One end of the hydraulic cylinder on the snowplow is installed on the holes on both sides of the mounting plate 7 to push the outer box 1 to rotate, thereby adjusting the direction of the snow removal device.

[0060] In order to further adjust the angle of the snow-clearing assembly 3 and make the replacement process of the snow-clearing assembly 3 more convenient, this embodiment adds a limiting structure for the snow-clearing assembly 3, which should be adjusted to a better angle for replacement. The specific implementation method is as follows: the snow-clearing assembly 3 is rotatably connected to the snow guard 2, and a telescopic tube 8 is rotatably connected between the two sides of the snow-clearing assembly 3 and the outer box 1. When the adjustment assembly 6 drives the snow guard 2 to rotate, the snow guard 2 drives the top end of the snow-clearing assembly 3 to rise. Since one side of the snow-clearing assembly 3 is limited by the telescopic tube 8 and the outer box 1, the snow-clearing assembly 3 is always in a vertical direction during the rising process. At this time, the angle at which the snow-clearing assembly 3 is blocked by the snow guard 2 is small, and it can be replaced at a larger angle from the side of the snow-clearing assembly 3 away from the outer box 1.

[0061] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

2. A method for using a self-cleaning snow removal device, using the self-cleaning snow removal device according to claim 1, comprising the following steps: S1. When snow accumulates on the road and affects driving safety, the self-cleaning snow removal device is activated and the device performs snow removal operations at a rated speed of 200r / min to clear the snow on the road; S2. After the snow removal device has been working for a period of time, ice and snow adhere to the integrated roller brush (32), the snow removal function of the device decreases, the snow on the road after cleaning becomes thicker, and the snow accumulation causes the pressure alarm (44) to sound an alarm. The specific steps are as follows: S2-1): After the snow on the road is cleared, the roller (42) drives the connected longitudinal rod (43) to compress the spring (45) with a spring constant K of 0.1N / mm, causing the spring (45) to deform, and the deformation amount is recorded as X; S2-2): According to Hooke's law: F=KX, calculate the pressure value F of the spring (45) on the pressure alarm (44); S2-3): When the snow thickness exceeds 1mm and is not suitable for driving, the snow thickness H=1mm, that is, the deformation X=1mm occurs, and the pressure value F=0.1N of the pressure alarm (44); S2-4): The pressure alarm (44) determines whether to sound an alarm based on the pressure value F: ① If F < 0.1N, it is determined that the cleared road surface H < 1mm, the pressure alarm (44) does not sound an alarm, and the device continues to clear the snow on the road; ② If F>0.1N, it is judged that the cleared road surface H>1mm, the snow thickness on the road exceeds the allowable range, and the pressure alarm (44) sounds an alarm; S3: After the snow removal device issues an alarm, the snow scraping assembly (3) is activated to scrape off the ice and snow adhered to the integrated roller brush (32) and restore the snow removal function of the device. The specific steps are as follows: When the pressure alarm (44) sounds an alarm, the snow scraping assembly (3) starts working, and the first hydraulic telescopic cylinder (52) in the snow scraping assembly (3) drives the snow scraping blade (54) to do reciprocating motion. When the snow scraping blade (54) and the integrated roller brush (32) are fully in contact and rubbed, the ice and snow adhered to the integrated roller brush (32) can be removed, so that the snow removal function of the snow removal device is restored, the thickness of the snow on the road is reduced, and the pressure value F of the pressure alarm (44) is reduced. When F<0.1N, the pressure alarm (44) stops sounding the alarm; S4. After the snow scraping assembly (3) is started to scrape off the ice and snow adhered to the integrated roller brush (32), if the pressure alarm (44) stops sounding the alarm, it is determined that the integrated roller brush (32) is not worn. If the pressure alarm (44) continues to sound the alarm, it is determined that the integrated roller brush (32) is worn. The specific judgment steps are as follows: S4-1): Set the time t for the snow scraper component (3) to clean the snow removal device: The rotation period f of the integrated roller brush (32) is 0.3 s / rad, and the reciprocating period f of the snow scraper (54) is 10 s / time. The greatest common divisor of the two times is 30 s, that is, when the snow removal time t of the snow scraper (54) is 30 s, the snow scraper (54) can completely clean the integrated roller brush (32); S4-2): The wear condition of the integrated roller brush (32) is determined by the relationship between the time T when the pressure alarm (44) issues an alarm and 30 seconds: ① If T < 30s, it is a short-term alarm, and it is determined that the snow removal device has a poor snow removal effect due to ice and snow adhering to the integrated roller brush (32). After the snow scraping component (3) is started, the snow removal function of the snow removal device is restored, and there is no need to replace the integrated roller brush (32); ② If T>30s, it is a continuous alarm function, that is, after the snow scraper (54) scrapes off the ice and snow on the integrated roller brush (32), the snow removal device cannot restore the snow removal function, and it is determined that the integrated roller brush (32) is worn and needs to be replaced; S5. After the integrated roller brush (32) of the snow removal device is worn, the integrated roller brush (32) is replaced. After the replacement, the device continues to perform snow removal operations. The specific replacement steps are as follows: When replacing the integrated roller brush (32), the adjustment component (6) is started, and the second hydraulic telescopic cylinder (62) and the third hydraulic telescopic cylinder (65) of the adjustment component (6) are simultaneously retracted, so that the snow guard (2) and the bending rod (63) rotate clockwise, driving the snow-clearing component (3) below the snow guard (2) to rise, and the integrated roller brush (32) is replaced at this time.

3. The self-cleaning snow removal device according to claim 1, characterized in that: One side of the outer box (1) is fixedly connected to three mounting plates (7), the third hydraulic telescopic cylinder (65) is mounted on the mounting plate (7), and a plurality of circular holes penetrating the mounting plate (7) are provided on the top of the mounting plate (7).

4. The self-cleaning snow removal device according to claim 1, characterized in that: The snow-clearing assembly (3) is rotatably connected to the snow guard (2), and telescopic tubes (8) are rotatably connected between both sides of the snow-clearing assembly (3) and the outer box (1).
