Detailed Implementation

[0033] 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.

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0035] In related technologies, when snow removal devices clear snow from roads, snow in the air may adhere to the area around the snow-discharging drum of the device, and the snow adhering to the snow-discharging component can freeze. The applicant in this case found that when traditional snow-discharging components are irregularly shaped, triangular, or square, the snow-discharging drum needs to push the surrounding ice blocks to move when it rotates, which requires the snow-discharging drum to overcome greater resistance, making the rotation of the snow-discharging drum more difficult.

[0036] In view of this, please refer to Figure 1 and Figure 2This application proposes a snow ejection assembly 10, which can be applied to a snow removal device 20. The snow removal device 20 may have a snow throwing mechanism that can throw accumulated snow towards the snow ejection assembly 10, so that the snow is ejected from the snow ejection assembly 10. In the following embodiments, the snow ejection assembly 10 is mainly used as an example of its application to the snow removal device 20 for description and explanation. Other situations requiring the snow ejection assembly 10 can be referred to in the embodiments.

[0037] Please see Figure 2 and Figure 3 The snow discharge assembly 10 may include a snow discharge drum 100 and an annular sleeve 200. The snow discharge drum 100 may have an inlet end 110 and an outlet end 120 facing away from each other. The inlet end 110 is rotatably connected to the body 300 of the snow removal device 20. The annular sleeve 200 may be fitted onto the snow discharge drum 100 and located on one side of the inlet end 110 to rotate with the snow discharge drum 100. The outer ring surface 202 of the annular sleeve 200 is a cylindrical surface. Thus, when the snow attached to the snow discharge assembly 10 freezes, because the outer ring surface 202 of the annular sleeve 200 is a cylindrical surface, when the annular sleeve 200 rotates with the snow discharge drum 100, the annular sleeve 200 does not need to push the ice attached to the annular sleeve 200 to move a large distance, thereby reducing the resistance to the rotation of the annular sleeve 200 and making the rotation of the annular sleeve 200 easier. This, in turn, helps the snow removal device 20 to control the direction of snow discharge by rotating the snow discharge drum 100. The snow discharge assembly 10 of this application can make the rotation of the snow discharge drum 100 easier by adding an annular sleeve 200, and the shape and mold of the snow discharge drum 100 do not need to be changed or finely adjusted, which helps to reduce the design difficulty and production cost of the snow discharge drum 100.

[0038] The snow-discharging drum 100 can be located above the body 300 of the snow removal device 20, which facilitates the snow removal device 20 in throwing out snow, thereby making it easier for the snow removal device 20 to quickly remove snow from the road and improving the efficiency of the snow removal device 20 in removing snow from the road.

[0039] The outer contour of the snow discharge drum 100 can be roughly arc-shaped. For example, the snow discharge drum 100 can be arc-shaped and extend from the inlet end 110 in a direction away from the rotation axis of the inlet end 110, so that the snow removal device 20 can control the snow discharge direction of the snow discharge component 10, which is beneficial for the snow removal device 20 to throw out the snow.

[0040] The inlet end 110 and the outlet end 120 of the snow discharge drum 100 are the two ends of the snow discharge drum 100. The inlet end 110 is the end of the snow discharge drum 100 connected to the body 300 of the snow removal device 20, and the outlet end 120 is the end of the snow discharge drum 100 away from the body 300 of the snow removal device 20.

[0041] There are several ways in which the inlet end 110 can be rotatably connected to the body 300 of the snow removal device 20. For example, the inlet end 110 can be rotatably connected to the body 300 of the snow removal device 20 via a bearing; or, for another example, the inlet end 110 can be provided with a rotating shaft, and the body 300 of the snow removal device 20 can be provided with a rotating groove, with the rotating shaft of the inlet end 110 located in the rotating groove of the body 300 of the snow removal device 20, thereby allowing the inlet end 110 to be rotatably connected to the body 300 of the snow removal device 20.

[0042] The annular sleeve 200 and the snow discharge rotating drum 100 can be connected together in various ways so that the annular sleeve 200 can rotate with the snow discharge rotating drum 100.

[0043] In some embodiments, the annular sleeve 200 and the snow-discharging rotating drum 100 are detachably connected, which facilitates the manufacturing of both and their assembly. For example, the annular sleeve 200 and the snow-discharging rotating drum 100 can be connected via a snap-fit ​​structure. Alternatively, the annular sleeve 200 and the snow-discharging rotating drum 100 can be fixed together using fasteners such as screws, bolts, studs, etc. This facilitates the fixed connection of the annular sleeve 200 to the snow-discharging rotating drum 100, allowing the annular sleeve 200 to rotate with the snow-discharging rotating drum 100. In other embodiments, the annular sleeve 200 and the snow-discharging rotating drum 100 can also be detachably connected using other methods.

[0044] Please see Figure 4 The snow-discharging rotary drum 100 may include a first connecting plate 102, a second connecting plate 103, and a third connecting plate 104. The first connecting plate 102 and the third connecting plate 104 may be disposed on both sides of the second connecting plate 103. The first connecting plate 102 may be parallel to the third connecting plate 104, and the second connecting plate 103 may be an arc-shaped plate structure, thereby facilitating the formation of a snow-guiding groove 106 by the first connecting plate 102, the second connecting plate 103, and the third connecting plate 104, which in turn facilitates the snow removal device 20 to discharge snow through the snow-guiding groove 106.

[0045] In some embodiments, the first connecting plate 102, the second connecting plate 103 and the third connecting plate 104 can be integrally formed, thereby saving the assembly process of the snow discharge drum 100, and also helping to improve the strength of the snow discharge drum 100, as well as helping to reduce the number of parts of the snow discharge assembly 10 and improve the assembly efficiency of the snow discharge assembly 10.

[0046] In other embodiments, the first connecting plate 102, the second connecting plate 103, and the third connecting plate 104 can also be spliced ​​together. For example, the first connecting plate 102, the second connecting plate 103, and the third connecting plate 104 can be spliced ​​together in sequence to form the snow discharge drum 100, thereby facilitating the manufacture of the snow discharge drum 100 and reducing the manufacturing cost of the snow discharge drum 100.

[0047] The snow-discharging drum 100 may also have an opening 101, which may be located on the concave side of the snow-discharging drum 100 and may extend from the inlet end 110 to the outlet end 120. Because the snow-discharging drum 100 is arc-shaped, during the process of snow being thrown out of the snow-discharging drum 100, the snow will be thrown away from the concave side of the snow-discharging drum 100, for example, the snow will be thrown along the second connecting plate 103; while the portion of the snow-discharging drum 100 located on the concave side, such as the portion opposite the second connecting plate 103, will not have much or no contact with the snow. Thus, the opening 101 helps reduce the amount of material used in manufacturing the snow-discharging drum 100, facilitating its manufacturing and reducing its manufacturing cost. Furthermore, the opening 101 also helps reduce the obstruction of the snow-discharging drum 100 to snow discharge, which is beneficial for the snow removal device 20 to discharge snow quickly, thereby improving the snow removal efficiency of the snow removal device 20. The concave side of a curved surface refers to a surface where the normal vector at any point on the surface points inwards. The concave side of the snow-discharging drum 100 refers to the region on one side where the radius of curvature of all surfaces constituting the snow-discharging drum 100 is negative, for example, in the attached... Figure 4 The area on one side of the space occupied by the central snow trough 106.

[0048] In some embodiments, the opening 101 may be connected to the snow guide chute 106. Since the snow throwing mechanism of the snow device 20 throws the snow at different speeds toward the snow discharge assembly 10, when the snow reaches the snow discharge assembly 10 with greater kinetic energy, the snow can be thrown along the inner wall of the snow discharge drum 100; when the snow reaches the snow discharge assembly 10 with less kinetic energy, the snow can be thrown out from the opening 101, which is beneficial for the snow removal device 20 to quickly throw out the snow and avoid the snow discharge drum 100 obstructing the snow with less kinetic energy.

[0049] Please see Figure 2 and Figure 3 The snow-discharging rotary drum 100 has a first locking structure 130 on the side facing the annular sleeve 200, and a second locking structure 230 on the inner ring surface 201 of the annular sleeve 200. The second locking structure 230 is engaged with the first locking structure 130, so that the snow-discharging rotary drum 100 can be connected to the annular sleeve 200 through the first locking structure 130, thus fixing the annular sleeve 200 to the snow-discharging rotary drum 100, which facilitates the rotation of the annular sleeve 200 with the snow-discharging rotary drum 100. In addition, the first locking structure 130 and the second locking structure 230 make the connection between the annular sleeve 200 and the snow-discharging rotary drum 100 simple, easy to operate, and low in cost.

[0050] There are several ways to connect the first snap-fit ​​structure 130 and the second snap-fit ​​structure 230. Specifically, the first snap-fit ​​structure 130 and the second snap-fit ​​structure 230 can be connected in a block-to-block manner.

[0051] For example, the first snap-fit ​​structure 130 may include a protruding rib, which may protrude from the snow-discharging rotating cylinder 100, for example, the protruding rib may protrude from the outer periphery of the snow-discharging rotating cylinder 100. The second snap-fit ​​structure 230 may include a hook, which may protrude from the annular sleeve 200, for example, the hook may protrude from the inner annular surface 201 of the annular sleeve 200. The hook is opposite to the protruding rib and can hook the protruding rib, so that the snow-discharging rotating cylinder 100 and the annular sleeve 200 can be snapped together.

[0052] For example, the first engaging structure 130 may include a hook that protrudes from the snow-discharging rotating cylinder 100, for example, the hook may protrude from the outer periphery of the snow-discharging rotating cylinder 100. The second engaging structure 230 may include a rib that protrudes from the annular sleeve 200, for example, the rib may protrude from the inner annular surface 201 of the annular sleeve 200. The hook is opposite to the rib and can hook onto the rib, thus enabling the snow-discharging rotating cylinder 100 and the annular sleeve 200 to engage with each other.

[0053] For example, both the first snap-fit ​​structure 130 and the second snap-fit ​​structure 230 may include snap hooks, and the snap hooks of the two can hook each other to achieve mutual engagement between the snow discharge rotary drum 100 and the annular sleeve 200.

[0054] The first snap-fit ​​structure 130 and the second snap-fit ​​structure 230 can also be engaged using blocks and slots.

[0055] For example, the first snap-fit ​​structure 130 may include a hook that protrudes from the snow-discharging rotating cylinder 100, such as on the outer periphery of the snow-discharging rotating cylinder 100. The second snap-fit ​​structure 230 may have a groove, with the hook facing the groove and able to be embedded in it, so that the snow-discharging rotating cylinder 100 and the annular sleeve 200 can be engaged.

[0056] For example, the first snap-fit ​​structure 130 may be provided with a slot, and the second snap-fit ​​structure 230 may be provided with a hook. The hook is opposite to the slot and can be embedded in the slot, which also enables the snow-discharging rotary drum 100 and the annular sleeve 200 to engage.

[0057] In other embodiments, the first snap-fit ​​structure 130 and the second snap-fit ​​structure 230 may also be engaged in other ways.

[0058] Please see Figure 1 , Figure 2 and Figure 5 The outer contour of the annular sleeve 200 can be roughly arranged in an annular shape, so that the annular sleeve 200 can be fitted onto the snow discharge rotating cylinder 100.

[0059] The annular sleeve 200 may have a notch 203, which may be opposite to the opening 101, so that the notch 203 can avoid the opening 101, thereby reducing the obstruction of snow discharge and improving the snow discharge efficiency.

[0060] The annular sleeve 200 may have an inner annular surface 201 and an outer annular surface 202 facing away from each other. The inner annular surface 201 may be opposite to the snow discharge drum 100, and the outer annular surface 202 may be set away from the snow discharge drum 100.

[0061] The roughness Ra of the outer ring surface 202 is less than 1. For example, the roughness Ra of the outer ring surface 202 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. Thus, the outer ring surface 202 is relatively smooth, making it easier for snow to slide off the outer ring surface 202 of the annular sleeve 200. This helps reduce snow adhesion to the outer ring surface 202 of the annular sleeve 200 and also helps reduce the friction between the annular sleeve 200 and the ice accumulated around the annular sleeve 200, facilitating the rotation of the annular sleeve 200.

[0062] In some embodiments, the roughness Ra of the outer ring surface 202 is less than 0.8. For example, the roughness Ra of the outer ring surface 202 can be, but is not limited to, 0.79, 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. Thus, the outer ring surface 202 is relatively smooth, making it easier for snow to slide off the outer ring surface 202 of the annular sleeve 200. This helps reduce snow adhesion to the outer ring surface 202 of the annular sleeve 200 and also helps reduce the friction between the annular sleeve 200 and the ice accumulated around the annular sleeve 200, facilitating the rotation of the annular sleeve 200.

[0063] The outer ring surface 202 can be a layer of material made of nylon; for example, the outer ring surface 202 can be a layer of material made of polytetrafluoroethylene, making the outer ring surface 202 smoother, so that snow can easily slide off the outer ring surface 202 of the annular sleeve 200, which helps to reduce the snow adhering to the outer ring surface 202 of the annular sleeve 200, and also helps to reduce the friction between the annular sleeve 200 and the ice blocks accumulated around the annular sleeve 200, making it easier for the annular sleeve 200 to rotate.

[0064] Please see Figure 10The annular sleeve 200 may have a connecting end 210, which may be located on the side of the annular sleeve 200 away from the inlet end 110. The connecting end 210 is connected to the snow discharge rotating drum 100. Specifically, there are many ways to connect the connecting end 210 to the snow discharge rotating drum 100. For example, the connecting end 210 may be connected to the snow discharge assembly 10 by screws; or the connecting end 210 may be connected to the snow discharge assembly 10 by a bayonet, which facilitates the connection between the connecting end 210 and the snow discharge sleeve, and thus facilitates the rotation of the annular sleeve 200 with the snow discharge rotating drum 100.

[0065] In some embodiments, the connecting end 210 may have an outer end face 211, which may be inclined from the outlet end 120 toward the outer ring surface 202. This helps the snow or ice to slide freely under its own weight, thereby preventing the ice or snow from adhering to the outer end face 211, and thus preventing the surface of the annular sleeve 200 from being covered with snow or ice, which facilitates the rotation of the annular sleeve 200.

[0066] In some embodiments, the outer end face 211 can be a smooth surface. For example, the smooth surface can be a plane with a low coefficient of friction, and the specific value of the coefficient of friction can be selected according to the actual situation; for another example, the smooth surface can be a layer of material made of nylon; for yet another example, the smooth surface can be a layer of material made of polytetrafluoroethylene, making the outer ring surface 202 smoother, thereby reducing the friction between the annular sleeve 200 and the ice accumulated around the annular sleeve 200, facilitating the rotation of the annular sleeve 200. In addition, since the snow removal equipment 20 inevitably vibrates the body 300 due to the movement of the internal mechanism during snow removal, this vibration helps the snow to slide off the smooth outer end face 211, helping to reduce the amount of snow adhering to the outer end face 211 of the annular sleeve 200, thereby reducing the accumulation of snow on top of the annular sleeve 200.

[0067] In some embodiments, the roughness Ra of the outer end face 211 is less than 1. For example, the roughness Ra of the outer end face 211 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. Thus, the outer end face 211 is relatively smooth, making it easier for snow to slide off, which helps reduce snow adhesion to the outer end face 211 of the annular sleeve 200. Furthermore, it helps reduce the friction between the outer end face 211 and the ice accumulated around the annular sleeve 200, facilitating the rotation of the annular sleeve 200.

[0068] In some embodiments, the roughness Ra of the outer end face 211 is less than 0.8. For example, the roughness Ra of the outer end face 211 can be, but is not limited to: 0.79, 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 makes the outer end face 211 relatively smooth, allowing snow to easily slide off the outer end face 211.

[0069] Please see Figures 5 to 9 The annular sleeve 200 may include multiple connecting parts 220, which can surround the snow-discharging rotating cylinder 100. The multiple connecting parts 220 are connected end to end to form the annular sleeve 200. In this way, the annular sleeve 200 can be spliced ​​together from multiple connecting parts 220. Since the manufacturing of a single connecting part 220 is relatively easy, the annular sleeve 200 formed by combining multiple connecting parts 220 helps to reduce manufacturing costs, thereby reducing the manufacturing cost of the snow-discharging component 10.

[0070] In some embodiments, multiple connecting parts 220 are integrally formed, thereby reducing the assembly process of the annular sleeve 200 and improving the strength of the annular sleeve 200.

[0071] Please see Figure 2 , Figure 6 and Figure 8 In some embodiments, the snow-discharging rotary drum 100 may include a first connecting plate 102, a second connecting plate 103, and a third connecting plate 104. The second connecting plate 103 is connected between the first connecting plate 102 and the third connecting plate 104. An opening 101 is provided between the first connecting plate 102 and the third connecting plate 104, and the opening 101 is opposite to the second connecting plate 103. The connecting sub-part 220 connected to the first connecting plate 102 is provided with a first limiting structure 206, which engages with the end of the first connecting plate 102 near the opening 101. The connecting sub-part 220 connected to the third connecting plate 104 is provided with a second limiting structure 207, which engages with the end of the third connecting plate 104 near the opening 101.

[0072] Specifically, both the first limiting structure 206 and the second limiting structure 207 can be limiting grooves, allowing the first connecting plate 102 to be inserted into the first limiting structure 206 and the second connecting plate 103 to be inserted into the second limiting structure 207; alternatively, both the first limiting structure 206 and the second limiting structure 207 can be limiting buckles, allowing the first limiting structure 206 to press against the first connecting plate 102 and the second limiting structure 207 to press against the third connecting plate 104; or alternatively, the first limiting structure 206 can be a limiting groove and the second limiting structure 207 can be a limiting buckle, thereby limiting the first connecting plate 102 and the third connecting plate 104 respectively. In this way, the first limiting structure 206 and the second limiting structure 207 can limit the first connecting plate 102 and the third connecting plate 104 respectively, thereby improving the firmness and stability of the connection between the first connecting plate 102 and the third connecting plate 104 and the annular sleeve 200.

[0073] In some embodiments, each connecting sub-part 220 may have a connecting structure 221 at both ends, and the connecting structures 221 of two adjacent connecting sub-parts 220 may abut against each other. In this way, the outer contour of the connecting structure 221 can be roughly arc-shaped, and the abutment of the connecting structures 221 of two adjacent connecting sub-parts 220 helps to increase the contact area of ​​the two adjacent connecting sub-parts 220, thereby improving the stability and reliability of the connection between the two adjacent connecting sub-parts 220.

[0074] In this embodiment, the annular sleeve 200 includes a first connecting sub-part 220a, a second connecting sub-part 220b, a third connecting sub-part 220c, and a fourth connecting sub-part 220d. The first connecting sub-part 220a, the second connecting sub-part 220b, the third connecting sub-part 220c, and the fourth connecting sub-part 220d are sequentially connected to form the annular sleeve 200. The first connecting sub-part 220a and the third connecting sub-part 220c are opposite to each other and spaced apart, and the second connecting sub-part 220b and the fourth connecting sub-part 220d are opposite to each other and spaced apart.

[0075] The connecting structure 221 in the first connecting sub-part 220a that connects to the second connecting sub-part 220b is located close to the outer ring surface 202, and the end face of the connecting structure 221 in the first connecting sub-part 220a that connects to the second connecting sub-part 220b facing the snow discharge cylinder 100 is S-shaped; correspondingly, the connecting structure 221 in the second connecting sub-part 220b that connects to the first connecting sub-part 220a is located close to the inner ring surface 201, and the end face of the connecting structure 221 in the second connecting sub-part 220b that connects to the first connecting sub-part 220a facing away from the snow discharge cylinder 100 is S-shaped. Thus, the contact surfaces of the first connecting sub-part 220a and the second connecting sub-part 220b are approximately S-shaped, which facilitates the fitting of the connecting structure 221 of the first connecting sub-part 220a and the connecting structure 221 of the second connecting sub-part 220b. This increases the contact area between the first connecting sub-part 220a and the second connecting sub-part 220b, thereby helping the annular sleeve 200 overcome the vibration generated by the movement of the internal mechanism during snow removal by the snow removal device 20, and improving the stability of the connection between the first connecting sub-part 220a and the second connecting sub-part 220b.

[0076] Furthermore, the contact surfaces of the first connecting sub-part 220a and the second connecting sub-part 220b are roughly S-shaped, which makes the path for external snow or dust and other impurities to enter between the snow discharge rotating cylinder 100 and the annular sleeve 200 more complicated, thereby hindering the entry of external snow or dust and other impurities between the snow discharge rotating cylinder 100 and the annular sleeve 200.

[0077] The connecting structure 221 in the second connecting sub-part 220b that connects to the third connecting sub-part 220c is located close to the inner ring surface 201, and the end face of the connecting structure 221 in the second connecting sub-part 220b that connects to the third connecting sub-part 220c that is away from the snow discharge cylinder 100 is arranged in an S-shape; correspondingly, the connecting structure 221 in the third connecting sub-part 220c that connects to the second connecting sub-part 220b is located close to the outer ring surface 202, and the end face of the connecting structure 221 in the third connecting sub-part 220c that connects to the second connecting sub-part 220b that is towards the snow discharge cylinder 100 is arranged in an S-shape. Thus, the contact surfaces of the second connecting sub-part 220b and the third connecting sub-part 220c are approximately S-shaped, which facilitates the fitting of the connecting structure 221 of the second connecting sub-part 220b with the connecting structure 221 of the third connecting sub-part 220c. This increases the contact area between the second connecting sub-part 220b and the third connecting sub-part 220c, thereby helping the annular sleeve 200 overcome the vibration generated by the movement of the internal mechanism during snow removal, and improving the stability of the second connecting sub-part 220b and the third connecting sub-part 220c.

[0078] Furthermore, the contact surfaces of the second connecting sub-part 220b and the third connecting sub-part 220c are roughly S-shaped, which makes the path for external snow or dust and other impurities to enter between the snow discharge drum 100 and the annular sleeve 200 more complicated, thus hindering the entry of external snow or dust and other impurities between the snow discharge drum 100 and the annular sleeve 200.

[0079] The connection structure 221 in the fourth connecting sub-part 220d that connects to the first connecting sub-part 220a is located below the connection structure 221 in the first connecting sub-part 220a that connects to the fourth connecting sub-part 220d. The connection structure 221 in the fourth connecting sub-part 220d that connects to the third connecting sub-part 220c is located below the connection structure 221 in the third connecting sub-part 220c that connects to the fourth connecting sub-part 220d. This facilitates the connection structure 221 in the first connecting sub-part 220a and the connection structure 221 in the third connecting sub-part 220c having slots, and the connection structures 221 at both ends of the fourth connecting sub-part 220d having pins. This makes it easier for the fourth connecting sub-part 220d to be inserted into the first connecting sub-part 220a and the third connecting sub-part 220c. Furthermore, the structure is simple and the cost is low.

[0080] Please see Figure 1 This application also proposes a snow removal device 20, which includes a body 300 and a snow discharge assembly 10, the snow discharge assembly 10 being rotatably connected to the body 300. The specific structure of the snow discharge assembly 10 is as described in the above embodiments. Since the snow removal device 20 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.

[0081] In some embodiments, the inlet end 110 of the snow discharge assembly 10 is rotatably connected to the body 300. For example, the inlet end 110 of the snow discharge assembly 10 can be rotatably connected to the body 300 of the snow removal device 20 via a bearing; or, for another example, the inlet end 110 of the snow discharge assembly 10 can be provided with a rotating shaft, and the body 300 of the snow removal device 20 can be provided with a rotating groove. The rotating shaft of the inlet end 110 of the snow discharge assembly 10 is provided in the rotating groove of the body 300 of the snow removal device 20, so that the inlet end 110 of the snow discharge assembly 10 can be rotatably connected to the body 300 of the snow removal device 20.

[0082] In some embodiments, the snow-throwing mechanism of the snow removal device 20 may include an impeller assembly, which may include multiple centrifugal impellers. The impeller assembly may be installed at the bottom of the machine body 300 and may directly contact the snow. When the centrifugal impellers rotate at high speed, the snow entrained by the centrifugal impellers is collected into the machine body 300 under the action of centrifugal force and thrown out through the snow discharge assembly 10.

[0083] This application also proposes a snow removal device, which includes a snow removal unit 20 and a self-moving device. The self-moving device can be connected to the body 300 of the snow removal unit 20 to carry the snow removal unit 20 for snow removal. The specific structure of the snow removal unit 20 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.

[0084] 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 can control the movement of the drive component. The drive component can be used to drive the snow removal device 20 to move. For example, the drive component may include multiple drive wheels, which may be located at the bottom of the body 300 to drive the snow removal device 20 to move.

[0085] In some embodiments, the snow removal equipment may also include an ultrasonic ranging sensor. This 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 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.
