[0001] This application claims priority to Chinese patent application filed on June 6, 2023, application number 2023214279804, entitled "Snow Removal Apparatus and Snow Removal Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of snow removal technology, and more specifically, to a snow removal device and snow removal equipment. Background Technology

[0003] In related technologies, snow removal devices generally include a main body and a snow-discharging drum. The snow-discharging drum is typically mounted on the main body and is rotatably connected to the main body to control the direction of snow discharge. However, in traditional snow removal devices, the friction between the snow-discharging drum and the main body is relatively high, making it difficult to rotate the snow-discharging drum. Summary of the Invention

[0004] This application provides a snow removal device and snow removal equipment to improve at least one of the above-mentioned problems.

[0005] The above objectives are achieved through the following technical solutions in the embodiments of this application.

[0006] In a first aspect, embodiments of this application provide a snow removal device applied to snow removal equipment. The snow removal device includes a main body, a rotating bracket, and a snow-discharging drum. The rotating bracket has a support surface, which is rotatably mounted on the main body. The angle α between the support surface and the rotation axis of the rotating bracket is an acute angle. The snow-discharging drum is connected to the rotating bracket to rotate relative to the main body.

[0007] In some implementations, the included angle α is greater than or equal to 30 degrees.

[0008] In some embodiments, the support surface is provided with a groove, which is opposite to the main body.

[0009] In some embodiments, a first protrusion and a second protrusion are provided on the side of the support surface facing the main body, and the first protrusion and the second protrusion are spaced apart to form a groove.

[0010] In some implementations, the rotating bracket is made of plastic.

[0011] In some implementations, the rotating bracket is a nylon bracket or a polytetrafluoroethylene bracket.

[0012] In some embodiments, the rotating bracket also has a contact surface, the contact surface and the support surface are located on opposite sides of the rotating bracket, the contact surface is rotatably disposed on the main body, and the angle β between the contact surface and the rotation axis of the rotating bracket is an acute angle.

[0013] In some implementations, the included angle β is greater than or equal to 30 degrees.

[0014] In some embodiments, the rotating bracket also has an arc-shaped abutment surface that connects the support surface and the contact surface and abuts against the main body.

[0015] In some implementations, at least one of the following conditions is met: the surface roughness Ra at any point on the support surface is less than 1; the surface roughness Ra at any point on the contact surface is less than 1; and the surface roughness Ra at any point on the arc-shaped abutment surface is less than 1.

[0016] In some embodiments, the snow removal device further includes a transmission structure, which is fixedly connected to the rotating bracket. The transmission structure is provided with a first insertion structure, and the rotating bracket is provided with a second insertion structure. The second insertion structure is inserted into the first insertion structure along the axial direction of the rotating bracket.

[0017] In some embodiments, one of the first plug-in structure and the second plug-in structure is a plug-in block, and the other of the first plug-in structure and the second plug-in structure is a plug-in groove, with the plug-in block inserted into the plug-in groove along the axial direction of the rotating bracket.

[0018] Secondly, this application also provides a snow removal device. The snow removal device includes a self-moving device and a snow removal device according to any of the above embodiments, wherein the self-moving device is connected to the main body.

[0019] The snow removal device and equipment provided in this application include a main body, a rotating bracket, and a snow-discharging drum. The rotating bracket has a supporting surface that is rotatably mounted on the main body. The angle α between the supporting surface and the rotation axis of the rotating bracket is acute. The snow-discharging drum is connected to the rotating bracket to rotate relative to the main body. Thus, the snow-discharging drum can be connected to the main body via the rotating bracket to rotate relative to the main body. Furthermore, the acute angle α between the supporting surface and the rotation axis of the rotating bracket reduces the normal pressure on the supporting surface, thereby reducing the friction between the snow-discharging drum and the rotating bracket relative to the main body, facilitating the rotation of the snow-discharging drum by the rotating bracket. Compared to snow removal devices in related technologies, this application reduces the friction between the snow-discharging drum and the main body by adding a rotating bracket, thus facilitating the rotation of the snow-discharging drum. It also features a simple structure, easy replacement, and low cost. Furthermore, the support surface is erected on the main body, so that the main body can support the rotating bracket through the support surface. During the rotation of the rotating bracket relative to the main body, the support surface of the rotating bracket can reduce the frictional force between it and the main body under the action of centrifugal force.

Detailed Implementation

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0039] In related technologies, the applicant of this application found that the direction of the pressure exerted by the snow discharge drum on the main body is generally set along the axial direction of the snow discharge drum, and the mass of the snow discharge drum is relatively large. The gravity of the snow discharge drum acts directly on the main body, resulting in a large frictional force between the snow discharge drum and the main body, thereby affecting the rotation of the snow discharge drum.

[0040] In view of this, please refer to Figure 1 This application provides a snow removal device 10, which can be applied to snow removal equipment. The following embodiments primarily use the application of the snow removal device 10 in snow removal equipment as an example for explanation; other situations requiring the snow removal device 10 can refer to these embodiments.

[0041] Please see Figures 2 to 6The snow removal device 10 may include a main body 100, a rotating bracket 200, and a snow-discharging drum 300. The rotating bracket 200 may have a support surface 201 (see...). Figure 6 The support surface 201 is rotatably disposed on the main body 100. The angle α between the support surface 201 and the rotation axis O of the rotating bracket 200 is an acute angle. The snow-discharging drum 300 can be connected to the rotating bracket 200 to rotate relative to the main body 100 along with the rotating bracket 200. In this way, the snow-discharging drum 300 can be connected to the main body 100 through the rotating bracket 200 to rotate relative to the main body 100 along with the rotating bracket 200. The acute angle α between the support surface 201 and the rotation axis O of the rotating bracket 200 reduces the normal pressure on the support surface 201, thereby helping to reduce the friction between the snow-discharging drum 300 and the rotating bracket 200 relative to the main body 100, and facilitating the rotation of the snow-discharging drum 300 by the rotating bracket 200. Compared with snow removal devices in related technologies, this application reduces the friction between the snow discharge drum 300 and the main body 100 by adding a rotating bracket 200, thereby facilitating the rotation of the snow discharge drum 300. It also has a simple structure, is easy to replace, and has a low cost.

[0042] Furthermore, the support surface 201 is mounted on the main body 100, so that the main body 100 supports the rotating bracket 200 through the support surface 201. During the rotation of the rotating bracket 200 relative to the main body 100, the support surface 201 of the rotating bracket 200 can move away from the main body 100 under the action of centrifugal force, thereby reducing the degree of pressing between the support surface 201 and the main body 100 (reducing the normal pressure of friction between the main body 100 and the support surface 201), and thus reducing the frictional force between the support surface 201 and the main body 100.

[0043] Understandably, in related snow removal devices, the weight of the snow-discharging drum is equal to the magnitude of the normal force of friction between the snow-discharging drum and the main body. In the applied technical solution, the weight of the snow-discharging drum 300 and the rotating support 200 can be decomposed into a component force parallel to the support surface 201 and a component force perpendicular to the support surface 201. The magnitude of the component force perpendicular to the support surface 201 is equal to the magnitude of the normal force of friction between the snow-discharging drum 300 and the rotating support 200 and the main body 100. In this application, the magnitude of the normal force of friction between the snow-discharging drum 300 and the main body 100 is smaller than that in related technologies, resulting in a smaller frictional force between the rotating support 200 and the main body 100, thus facilitating the rotation of the snow-discharging drum 300 by the rotating support 200.

[0044] The main body 100 can have various options. For example, the main body 100 can be the fuselage of the snow removal device 10; or the main body 100 can be the frame of the snow removal device 10. In this embodiment, the main body 100 is mainly described as the fuselage.

[0045] The support surface 201 can support the snow discharge cylinder 300 and the rotating bracket 200 so that the weight of the snow discharge cylinder 300 and the rotating bracket 200 can be applied to the main body 100. In other words, the support surface 201 can be located at the end of the rotating bracket 200 away from the snow discharge cylinder 300 so that the weight of the snow discharge cylinder 300 can be applied to the main body 100 through the rotating bracket 200.

[0046] The support surface 201 is erected on the main body 100 so that the support surface 201 can directly abut against the main body 100. When the rotating bracket 200 rotates, the main body 100 supports the rotating bracket 200 and the snow discharge cylinder 300 through the support surface 201, so that the support surface 201 can transmit the force to the main body 100.

[0047] The angle α between the support surface 201 and the rotation axis O of the rotating bracket 200 is greater than or equal to 60 degrees. Specifically, the angle α between the support surface 201 and the rotation axis O of the rotating bracket 200 can be, but is not limited to, 30 degrees, 33 degrees, 35 degrees, 37 degrees, 40 degrees, 43 degrees, 45 degrees, 47 degrees, 50 degrees, 53 degrees, 55 degrees, 57 degrees, 60 degrees, 63 degrees, 65 degrees, 67 degrees, 70 degrees, 73 degrees, 75 degrees, 77 degrees, 80 degrees, 83 degrees, 85 degrees, 87 degrees, and 89 degrees. This ensures that the angle α between the support surface 201 and the rotation axis O of the rotating bracket 200 is not too small, which helps to reduce the contact area between the support surface 201 and the main body 100, thereby effectively reducing friction between them.

[0048] The support surface 201 may be provided with a groove 202, which may be opposite to the main body 100. In this way, the groove 202 can reduce the contact area between the support surface 201 and the main body 100, thereby reducing friction between the support surface 201 and the main body 100, and thus helping to reduce wear on the rotating bracket 200. Furthermore, when there are impurities such as dust or sand between the support surface 201 and the main body 100, the groove 202 can accommodate a certain amount of these impurities, preventing them from jamming the rotating bracket 200 and facilitating its rotation relative to the main body 100.

[0049] The support surface 201 may have a first protrusion 202a and a second protrusion 202b on the side facing the main body 100. The second protrusion 202b may be located above the first protrusion 202a. The first protrusion 202a and the second protrusion 202b may form a groove 202 at intervals. Specifically, the first protrusion 202a protrudes from the support surface 201 toward the main body 100, and the second protrusion 202b also protrudes from the support surface 201 toward the main body 100. The first protrusion 202a and the second protrusion 202b form a groove 202 at intervals, that is, the support surface 201 can serve as the bottom of the groove 202, thereby avoiding the support surface 201 being recessed in a direction away from the main body 100, which helps to improve the strength of the rotating bracket 200.

[0050] In some embodiments, the rotating bracket 200 is a plastic bracket, which prevents it from rusting due to prolonged exposure to a humid environment, thus improving its stability and reliability. Furthermore, the rotating bracket 200 also possesses advantages such as strong corrosion resistance, low manufacturing cost, light weight, and ease of molding into different shapes, further enhancing its stability and reliability.

[0051] In some embodiments, the rotating bracket 200 can be a nylon bracket or a polytetrafluoroethylene bracket, which helps to make the support surface 201 of the rotating bracket 200 smoother, reducing the friction between the support surface 201 and the main body 100, thereby helping the rotating bracket 200 to rotate relative to the main body 100, and at a lower cost.

[0052] In some embodiments, the rotating bracket 200 may also have a contact surface 203. The contact surface 203 and the supporting surface 201 may be located on opposite sides of the rotating bracket 200. The contact surface 203 is rotatably disposed on the main body 100, and the angle β between the contact surface 203 and the rotation axis O of the rotating bracket 200 may be an acute angle. Specifically, there are various ways in which the contact surface 203 is rotatably connected to the main body 100. For example, the surface of the contact surface 203 may be designed to be relatively smooth, and the contact surface 203 may abut against the main body 100, thereby facilitating the rotation of the contact surface 203 relative to the main body 100. In this way, the main body 100 can limit the rotation of the rotating bracket 200, which helps the rotating bracket 200 to rotate more stably relative to the main body 100.

[0053] The angle β between the contact surface 203 and the rotation axis O of the rotating support 200 is greater than or equal to 30 degrees. Specifically, the angle β between the contact surface 203 and the rotation axis O of the rotating support 200 can be 30 degrees, 33 degrees, 35 degrees, 37 degrees, 40 degrees, 43 degrees, 45 degrees, 47 degrees, 50 degrees, 53 degrees, 55 degrees, 57 degrees, 60 degrees, 63 degrees, 65 degrees, 67 degrees, 70 degrees, 73 degrees, 75 degrees, 77 degrees, 80 degrees, 83 degrees, 85 degrees, 87 degrees, and 89 degrees, etc. This ensures that the angle β between the contact surface 203 and the rotation axis O of the rotating support 200 is not too small, which helps to reduce the contact area between the contact surface 203 and the main body 100, thereby effectively reducing the friction between the contact surface 203 and the main body 100.

[0054] In some embodiments, the rotating bracket 200 may also have an arc-shaped abutment surface 204, which can connect the support surface 201 and the contact surface 203 and abut against the main body 100. Specifically, the arc-shaped abutment surface 204 can be the end face of the rotating bracket 200 facing the main body 100 and has an arc-shaped design. In this way, the arc-shaped abutment surface 204 can make line contact with the main body 100, making the contact area between the arc-shaped abutment surface 204 and the main body 100 smaller, thereby helping to reduce the friction between the arc-shaped abutment surface 204 and the main body 100, and thus reducing the wear of the rotating bracket 200 and the main body 100.

[0055] In some embodiments, the snow removal device 10 satisfies at least one of the following conditions: the roughness Ra of any point on the support surface 201 is less than 1; the roughness Ra of any point on the contact surface 203 is less than 1; and the roughness Ra of any point on the arc-shaped abutment surface 204 is less than 1. That is, the roughness Ra of any point on at least one of the support surface 201, the contact surface 203, and the arc-shaped abutment surface 204 is less than 1. Specifically, at least one point on the support surface 201, the contact surface 203, and the arc-shaped abutment surface 204 can be made to have a roughness Ra of less than 1 by an industrial grinding process; or, at least one point on the support surface 201, the contact surface 203, and the arc-shaped abutment surface 204 can be provided with a smooth material coating with a roughness Ra of less than 1; or, the rotating bracket 200 can be manufactured using a material with a roughness Ra of less than 1.

[0056] The surface roughness Ra of any point on at least one of the supporting surface 201, the contact surface 203, and the arc-shaped abutment surface 204 can be, but is not limited to, 0.99, 0.95, 0.9, 0.85, 0.8, 0.75, 0.7, 0.65, 0.6, 0.55, 0.5, 0.45, 0.4, 0.35, 0.3, 0.025, 0.2, 0.15, and 0.1. This results in less friction between the rotating bracket 200 and the main body 100, thereby facilitating the rotation of the rotating bracket 200 relative to the main body 100.

[0057] The main body 100 may include a main body 110, which may include an inner shell 112 and an outer shell 111 connected to each other. The outer shell 111 is located above the inner shell 112. The outer shell 111 and the inner shell 112 may form an installation space 101 and an annular opening 102. The annular opening 102 may communicate with the installation space 101. The rotating bracket 200 is located in the installation space 101.

[0058] The snow discharge drum 300 can be located above the main body 100 of the snow removal device 10. The snow discharge drum 300 can be arranged around the annular opening 102, which is conducive to the snow removal device 10 throwing out snow, thereby facilitating the snow removal device 10 to quickly remove snow from the road and improving the efficiency of the snow removal device 10 in removing snow from the road.

[0059] There are several ways to connect the snow-discharging drum 300 to the rotating bracket 200. For example, the snow-discharging drum 300 can be connected to the rotating bracket 200 by a buckle; or the snow-discharging drum 300 can be connected to the rotating bracket 200 by a screw; or the snow-discharging drum 300 can be connected to the rotating bracket 200 by a bolt.

[0060] Please see Figure 7 The snow-discharging rotary drum 300 may include a drum body 310 and an annular sleeve 320. The drum body 310 may have an inlet end 311 and an outlet end 312 facing away from each other. The inlet end 311 is rotatably connected to the main body 100. The annular sleeve 320 may be sleeved on the drum body 310 and located on one side of the inlet end 311. In this way, the annular sleeve 320 may be located around the drum body 310, and the annular sleeve 320 may rub against the surrounding snow, thereby reducing the wear of the drum body 310.

[0061] The outer contour of the rotating drum body 310 can be roughly arc-shaped. For example, the rotating drum body 310 can extend in an arc shape from the inlet end 311 toward the rotation axis away from the inlet end 311, which makes it easier for the snow removal device 10 to control the snow discharge direction and facilitates the snow removal device 10 to throw out the snow.

[0062] The inlet end 311 and the outlet end 312 of the rotating drum body 310 are the two ends of the rotating drum body 310. The inlet end 311 is the end of the rotating drum body 310 connected to the main body 100 of the snow removal device 10, and the outlet end 312 is the end of the rotating drum body 310 away from the main body 100 of the snow removal device 10.

[0063] There are several ways in which the inlet end 311 can be rotatably connected to the main body 100 of the snow removal device 10. For example, the inlet end 311 can be rotatably connected to the main body 100 of the snow removal device 10 via a bearing; or, for another example, the inlet end 311 can be provided with a rotating shaft, the main body 100 of the snow removal device 10 can be provided with a rotating groove, and the rotating shaft of the inlet end 311 is provided in the rotating groove of the main body 100 of the snow removal device 10, so that the inlet end 311 can be rotatably connected to the main body 100 of the snow removal device 10.

[0064] The annular sleeve 320 and the rotating drum body 310 can be connected together in a variety of ways so that the annular sleeve 320 can rotate with the rotating drum body 310.

[0065] In some embodiments, the annular sleeve 320 can be detachably connected to the rotating drum body 310, for example, by means of a snap-fit ​​structure. Alternatively, the annular sleeve 320 and the rotating drum body 310 can be fixed together using fasteners such as screws, bolts, studs, etc. This facilitates the manufacturing of the annular sleeve 320 and the rotating drum body 310, and also facilitates their assembly. In other embodiments, the annular sleeve 320 and the rotating drum body 310 can also be detachably connected in other ways.

[0066] The main body 100 may further include a first connecting bracket 120, one end of which is fixedly connected to the rotating drum body 310 and the annular sleeve 320, and the other end of which is rotatably connected to the outer shell 111 and the inner shell 112, and is arranged around the annular opening 102. In this way, the first connecting bracket 120 can wear with the outer shell 111 and the inner shell 112, thereby helping to reduce the wear of the annular sleeve 320 and the rotating body.

[0067] The main body 100 may further include a second connecting bracket 130, which may be located between the first connecting bracket 120 and the inner shell 112. The second connecting bracket 130 is also fixedly connected to the inner shell 112 and is arranged around the annular opening 102. In this way, the second connecting bracket 130 can rotate relative to the first connecting bracket 120, and the second connecting bracket 130 can wear against the first connecting bracket 120, thereby helping to reduce the wear of the inner shell 112.

[0068] In some implementations, please refer to Figure 8 and Figure 9 The second connecting bracket 130 may be provided with a first plane 131, which can abut against the support surface 201. The contact between the surfaces makes the connection between the rotating bracket 200 and the second connecting bracket 130 more stable and reliable, thereby improving the stability and reliability of the rotating bracket 200.

[0069] The main body 100 may also include a third connecting bracket 140, which may be located between the rotating bracket 200 and the third connecting bracket 140. The third connecting bracket 140 may be arranged around the annular opening 102. The third connecting bracket 140 may be fixedly connected to the second connecting bracket 130 so that the rotating bracket 200 may rotate relative to the third connecting bracket 140.

[0070] In some implementations, please refer to Figure 10 and Figure 11 The third connecting bracket 140 may be provided with a second plane 141, which can abut against the contact surface 203. The contact between the surfaces makes the connection between the rotating bracket 200 and the third connecting bracket 140 more stable and reliable, thereby improving the stability and reliability of the rotating bracket 200.

[0071] In some embodiments, the second plane 141 and the first plane 131 are arranged at an angle, with the second plane 141 located above the first plane 131, so that the first plane 131 and the second plane 141 form a limiting space (not labeled in the figure). The support surface 201, the contact surface 203 and the arc-shaped abutment surface 204 can enable the rotating bracket 200 to form a cone 205. The cone 205 can be located in the limiting space, so that the second connecting bracket 130 and the third connecting bracket 140 can limit the rotating bracket 200 in the axial direction. The structure is simple and the cost is low.

[0072] Please see Figure 13 and Figure 14 The snow removal device 10 may also include a transmission structure 400, which may be fixedly connected to the rotating bracket 200. The transmission structure 400 may rotate under the drive of a power source, thereby driving the rotating bracket 200 to rotate. The power source may be a motor or a cylinder, etc. The transmission structure 400 may be a gear disk or a ring, etc.

[0073] The transmission structure 400 can be fixedly connected to the rotating bracket 200 in several ways. For example, the transmission structure 400 can be fixedly connected to the rotating bracket 200 by screws; another example is that the transmission structure 400 can be fixedly connected to the rotating bracket 200 by a snap-fit; yet another example is that the transmission structure 400 can be fixedly connected to the rotating bracket 200 by bolts.

[0074] The transmission structure 400 may be provided with a first insertion structure 410, and the rotating bracket 200 may be provided with a second insertion structure 210. The second insertion structure 210 can be inserted into the first insertion structure 410 along the axial direction of the rotating bracket 200. In this way, the second insertion structure 210 is inserted into the first insertion structure 410 along the axial direction of the rotating bracket 200, allowing for radial positioning between the transmission structure 400 and the rotating bracket 200. This helps overcome the influence of centrifugal force during rotation, reduces the risk of radial loosening of the transmission structure 400 and the rotating bracket 200 during rotation, and improves the stability and reliability of the connection between the transmission structure 400 and the rotating bracket 200.

[0075] In some embodiments, one of the first insertion structure 410 and the second insertion structure 210 is an insertion block, and the other of the first insertion structure 410 and the second insertion structure 210 is an insertion slot. The insertion block is inserted into the insertion slot along the axial direction of the rotating bracket 200.

[0076] Specifically, the first insertion structure 410 can be an insertion block, and correspondingly, the second insertion structure 210 can be an insertion slot; or, the first insertion structure 410 can be an insertion slot, and correspondingly, the second insertion structure 210 can be an insertion block, so that the first insertion structure 410 can be inserted and mated with the second insertion structure 210. In this way, the structure and assembly of the first insertion structure 410 and the second insertion structure 210 are relatively simple, and the cost is low.

[0077] The snow removal device 10 also includes a first sealing element 510, which can be a silicone seal or a rubber seal. The first sealing element 510 can be connected between the first connecting bracket 120 and the outer shell 111 to prevent impurities such as snow, ice, sand, dust, and water from entering the installation space 101 from the connection between the outer shell 111 and the first connecting bracket 120. This reduces the impact of impurities on the support surface 201 of the rotating bracket 200, thereby enabling the rotating bracket 200 to rotate normally and improving the reliability and stability of the rotating bracket 200.

[0078] The snow removal device 10 may also include a second seal 520, which may be a silicone seal or a rubber seal. The second seal 520 may be connected between the first connecting bracket 120 and the third connecting bracket 140, and enter the installation space 101 through the connection between the first connecting bracket 120 and the second connecting bracket 130. This reduces the impact of impurities on the support surface 201 of the rotating bracket 200, thereby enabling the rotating bracket 200 to rotate normally and improving the reliability and stability of the rotating bracket 200.

[0079] The snow removal device 10 may also include a third seal 530, which may be a silicone seal or a rubber seal. The third seal 530 may be connected between the rotating bracket 200 and the third connecting bracket 140 to prevent snow, ice, sand, dust, water and other impurities from moving from the connection between the rotating bracket 200 and the third connecting bracket 140 to the connection between the contact surface 203 and the second plane 141, and the connection between the support surface 201 and the first plane 131. This helps to ensure that the rotating bracket 200 can rotate stably relative to the second connecting bracket 130 and the third connecting bracket 140.

[0080] In some embodiments, the snow removal device 10 may include an impeller assembly, which may include multiple centrifugal impellers. The impeller assembly may be installed at the bottom of the main body 100 and may be in direct contact with the snow. When the centrifugal impellers rotate at high speed, the snow entrained by the centrifugal impellers is collected into the main body 100 under the action of centrifugal force and thrown out through the snow discharge drum 300.

[0081] This application also proposes a snow removal device, which includes a snow removal apparatus 10 and a self-moving device. The self-moving device can be connected to the main body 100 of the snow removal apparatus 10 to carry the snow removal apparatus 10 for snow removal. The specific structure of the snow removal apparatus 10 is as described in the above embodiments. Since the snow removal device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0082] In some embodiments, the self-moving device may include a control component and a drive component. The control component may include components such as a circuit board, and the control component can control the movement of the drive component. The drive component can be used to drive the snow removal device 10 to move. For example, the drive component may include drive wheels, and there may be multiple drive wheels. Multiple drive wheels may be disposed at the bottom of the main body 100 to drive the snow removal device 10 to move.

[0083] In some embodiments, the snow removal equipment may also include an ultrasonic ranging sensor. The snow removal equipment has path planning capabilities (i.e., obstacle handling capability). For small obstacles, the snow removal equipment can automatically cross them; for medium and large obstacles, it can avoid them in a timely manner and clear snow around the obstacles to the maximum extent possible. The transmitter of the ultrasonic ranging sensor in the snow removal equipment emits ultrasonic waves. When these ultrasonic waves encounter an obstacle and are reflected, the receiver of the ultrasonic ranging sensor can measure the distance from the obstacle to the snow removal equipment based on the time difference of the received ultrasonic waves. This allows the snow removal equipment to plan ahead to avoid obstacles, preventing collisions and effectively improving its safety performance. Of course, in other embodiments, the snow removal equipment may also utilize infrared ranging sensors or laser ranging sensors for obstacle avoidance.
