[0029] The technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application.

[0030] Please refer to Figure 1 The snow removing device 10 proposed in the embodiments of the present application can be applied to a snow removing device to remove snow on a road or snow in a yard. In the following embodiments, the snow removing device 10 is mainly taken as an example to be applied to a snow removing device for description and introduction, and other situations requiring the snow removing device 10 can refer to the implementation.

[0031] Please refer to Figures 1 to 3, the snow removing device 10 can include a body assembly 100 and a snow throwing cylinder 200, the body assembly 100 can include a body shell 110 and a snow prevention ring 120, the snow prevention ring 120 is separately formed with the body shell 110, the snow prevention ring 120 can be located above the body shell 110, the snow prevention ring 120 can be installed above the body shell 110, the side of the snow prevention ring 120 away from the body shell 110 can have a connecting end 121, the body assembly 100 can be provided with a containing space 101, the snow throwing cylinder 200 is rotatably connected to the body shell 110, one end of the snow throwing cylinder 200 towards the body shell 110 can be provided with an annular groove 201 which is communicated with the containing space 101 and has an opening downward, at least part of the connecting end 121 can be located in the annular groove 201, and the groove wall of the annular groove 201 has a gap L with the connecting end 121. In this way, the snow prevention ring 120 and the body shell 110 can be manufactured separately, the snow prevention ring 120 can be precisely machined, so that the snow prevention ring 120 can better cooperate with the snow throwing cylinder 200, thereby helping to control the size of the gap L between the groove wall of the annular groove 201 and the connecting end 121 within a predetermined range, and helping to reduce the risk of water, dust or silt and other impurities entering the containing space 101; the body shell 110 can be roughly machined, thereby helping to reduce the manufacturing cost of the body shell 110.

[0032] In addition, one end of the snow throwing cylinder 200 towards the body shell 110 is provided with an annular groove 201 which is communicated with the containing space 101 and has an opening downward, so that water, dust or silt and other impurities are difficult to enter the containing space 101 through the annular groove 201, helping to reduce the risk of water, dust or silt and other impurities entering the containing space 101, thereby helping to ensure that the rotating part 300 installed in the containing space 101 can work normally.

[0033] Moreover, the snow prevention ring 120 is located between the body shell 110 and the snow throwing cylinder 200, so that the snow throwing cylinder 200 is at a certain distance from the body shell 110, thereby avoiding the accumulated snow on the body shell 110 from freezing to freeze the snow throwing cylinder 200, thereby helping to ensure that the snow throwing cylinder 200 can rotate normally, and also helping to reduce the rotating resistance of the snow throwing cylinder 200. Moreover, the snow throwing cylinder 200 is at a certain distance from the body shell 110, so that the snow throwing cylinder 200 is not easy to contact the accumulated snow on the body shell 110, helping to reduce the friction between the snow throwing cylinder 200 and the accumulated snow on the body shell 110, thereby prolonging the service life of the snow throwing cylinder 200.

[0034] Please refer to Figure 1The fuselage shell 110 is the main frame of the snow removing device 10. The fuselage shell 110 can be made of a strong material, for example, the fuselage shell 110 can be made of aluminum alloy or hard plastic, so that the fuselage shell 110 can provide stable support performance, thereby ensuring the overall rigidity and stability of the snow removing device 10.

[0035] Referring to Figure 1 and Figure 2 The fuselage shell 110 can further include an inner shell 111 and an outer shell 112 connected to each other. The inner shell 111 forms a snow collecting space 102. The fuselage shell 110 can be provided with a snow outlet 103 communicating with the snow collecting space 102. The snow collecting space 102 is not in communication with the containing space 101, and the containing space 101 can be arranged around the snow outlet 103.

[0036] The snow removing device 10 can include an impeller assembly (not shown in the figure). The impeller assembly can be located in the snow collecting space 102. The impeller assembly can include a plurality of centrifugal impellers. The centrifugal impellers can include a plurality of snow sweeping blades. The impeller assembly can be installed at the bottom of the snow removing device 10. The impeller assembly can be directly in contact with the snow. When the centrifugal impellers rotate at high speed, the snow collected by the centrifugal impellers is collected into the snow collecting space 102 under the action of centrifugal force and thrown out of the snow outlet 103, and finally thrown out to the designated position through the snow throwing cylinder 200.

[0037] The fuselage shell 110 can further include a connecting piece 140. The connecting piece 140 can be connected between the inner shell 111 and the snow throwing cylinder 200. The connecting piece 140 can be arranged around the snow outlet 103. The connecting piece 140 can be arranged opposite and spaced apart from the snow prevention ring 120. The number of connecting pieces 140 can be multiple, for example, Figure 3 As shown in the figure, the number of connecting pieces 140 can be three. The three connecting pieces 140 can be arranged in sequence along the axial direction of the snow throwing cylinder 200 to connect the inner shell 111 and the snow throwing cylinder 200.

[0038] Referring to Figures 2 to 5 The connecting piece 140, the snow prevention ring 120, the inner shell 111 and the outer shell 112 enclose the containing space 101. The containing space 101 is not in communication with the snow collecting space 102, and the containing space 101 can be arranged around the snow outlet 103.

[0039] Referring to Figure 2 and Figure 5 The snow removing device 10 can further include a rotating component 300. The rotating component 300 can be installed in the containing space 101. The rotating component 300 can include gears, bearings and other components. The rotating component 300 can rotate under the action of a driving source, so as to drive the snow throwing cylinder 200 to rotate. The driving source can be a motor, a motor or other driving device.

[0040] The outer contour of the snow throwing cylinder 200 can be substantially cylindrical, and the end of the snow throwing cylinder 200 away from the fuselage assembly 100 can also be curved towards the fuselage assembly 100, so that the snow throwing cylinder 200 can better guide the snow to be thrown out. Wherein, the snow moves to the snow throwing cylinder 200 under the action of the impeller assembly, and continues to move along the guide direction of the snow throwing cylinder 200, so as to be thrown out to the designated place.

[0041] Please refer to Figure 1 and Figure 3 In some embodiments, the snow throwing cylinder 200 can include a snow throwing cylinder body 210, a first annular side wall 220 and a second annular side wall 230, the first annular side wall 220 and the second annular side wall 230 can be connected to the snow throwing cylinder body 210, the first annular side wall 220, the second annular side wall 230 and the snow throwing cylinder body 210 can be enclosed to form an annular groove 201, the first annular side wall 220 and the second annular side wall 230 can be located on both sides of the connecting end 121 respectively, and the first annular side wall 220 can be arranged opposite to the outer periphery of the connecting end 121.

[0042] The first annular side wall 220 can be provided with a first annular inclined surface 221 towards the outer periphery of the connecting end 121, the first annular inclined surface 221 is inclined downward from the second annular side wall 230 to the first annular side wall 220, the outer periphery of the connecting end 121 is provided with a second annular inclined surface 122, the second annular inclined surface 122 is inclined downward from the second annular side wall 230 to the outer periphery of the connecting end 121, and the second annular inclined surface 122 is opposite and spaced from the first annular inclined surface 221.

[0043] Specifically, since the first annular inclined surface 221 is inclined downward from the second annular side wall 230 to the first annular side wall 220, and the second annular inclined surface 122 is inclined downward from the second annular side wall 230 to the outer periphery of the connecting end 121. Therefore, the first annular side wall 220 can avoid the connecting end 121, and the connecting end 121 can also avoid the first annular side wall 220, so that the outer diameter of the first annular side wall 220 can be substantially the same as the outer diameter of the connecting end 121, thereby making the outer diameter of the snow throwing cylinder 200 and the outer diameter of the snow prevention ring 120 smaller, making the structure of the snow prevention ring 120 and the snow throwing cylinder 200 more compact, and the cost lower.

[0044] In addition, the first annular inclined surface 221 is inclined downward from the second annular side wall 230 to the first annular side wall 220, and the thickness of the first annular side wall 220 gradually increases from bottom to top, not only making the first annular side wall 220 can avoid the connecting end 121, but also making the first annular side wall 220 has higher strength.

[0045] Moreover, the second annular slope 122 is arranged downwardly from the second annular sidewall 230 to the outer periphery of the connecting end 121, and the thickness of the connecting end 121 gradually increases from top to bottom, so that the connecting end 121 can avoid the first annular sidewall 220 and has better strength.

[0046] In some embodiments, the first annular slope 221 has the same direction of inclination as the second annular slope 122. Specifically, the direction of inclination of the first annular slope 221 is parallel to the direction of inclination of the second annular slope 122; or the direction of inclination of the first annular slope 221 is substantially parallel to the direction of inclination of the second annular slope 122. In this way, the spacing between the first annular slope 221 and the first annular slope 221 can be designed to be more uniform, thereby helping to reduce the risk of interference between the snow throwing cylinder 200 and the snow prevention ring 120. In addition, when the first annular slope 221 and the second annular slope 122 accumulate more debris, it is also convenient for the operator to clean the first annular slope 221 and the second annular slope 122.

[0047] In some embodiments, the height of the first annular sidewall 220 is greater than the height of the second annular sidewall 230. In this way, the height of the first annular sidewall 220 is greater, which helps to shield the opening of the annular groove 201; the height of the second annular sidewall 230 is smaller, which helps to form a larger accommodation space 101 in the fuselage assembly 100, avoiding interference of the second annular sidewall 230 with the rotating part 300.

[0048] Please refer to Figure 3 In some embodiments, the gap L between the groove wall of the annular groove 201 and the connecting end 121 is 2mm-6mm. Wherein, the gap L between the groove wall of the annular groove 201 and the connecting end 121 can be, but is not limited to, 2mm, 2.3mm, 2.5mm, 2.8mm, 3mm, 3.3mm, 3.5mm, 3.8mm, 4mm, 4.3mm, 4.5mm, 4.85mm, 5.3mm, 5.5mm, 5.8mm or 6mm, etc. In this way, the gap L between the groove wall of the annular groove 201 and the connecting end 121 in this range helps to reduce the risk of interference between the snow throwing cylinder 200 and the snow prevention ring 120, thereby helping to reduce the friction between the snow throwing cylinder 200 and the snow prevention ring 120, and also helping to avoid water, dust or sand entering the accommodation space 101 due to the gap L being too large.

[0049] Please refer to Figure 2 and Figure 3In some embodiments, the snow throwing cylinder 200 can include a snow throwing cylinder body 240 and a protective sleeve 250. The snow throwing cylinder body 240 is rotatably connected to the fuselage shell 110. The protective sleeve 250 is sleeved on one end of the snow throwing cylinder body 240 close to the fuselage assembly 100. The one end of the protective sleeve 250 close to the fuselage assembly 100 is provided with an annular groove 201. The snow throwing cylinder body 240 and the protective sleeve 250 are formed separately.

[0050] Specifically, the outer periphery of the one end of the snow throwing cylinder 200 close to the fuselage shell 110 is prone to friction with the accumulated snow on the fuselage shell 110, thereby causing the outer periphery of the one end of the snow throwing cylinder 200 close to the fuselage shell 110 to be easily worn. Therefore, the protective sleeve 250 is sleeved on the outer periphery of the one end of the snow throwing cylinder body 240 close to the fuselage assembly 100, and the snow throwing cylinder body 240 and the protective sleeve 250 are formed separately, which helps to replace the snow throwing cylinder 200 and also avoids replacing the entire snow throwing cylinder 200, thereby helping to reduce maintenance costs.

[0051] In addition, the snow throwing cylinder body 240 and the protective sleeve 250 are formed separately, which also helps to detach the protective sleeve 250 from the snow throwing cylinder body 210 to clean the impurities in the annular groove 201, so that the snow throwing cylinder 200 is easy to maintain. Moreover, the snow throwing cylinder body 240 and the protective sleeve 250 are formed separately, which also helps to manufacture the snow throwing cylinder 200 and has a lower cost.

[0052] Please refer to Figures 5 to 7 In some embodiments, the snow protection ring 120 can include a connecting portion 123 and an annular side portion 124 connected together. The connecting portion 123 can be connected to and accommodated in the fuselage shell 110, for example, the fuselage shell 110 is provided with a slot hole for accommodating the connecting portion 123. The annular side portion 124 can protrude above the fuselage shell 110. The height H of the annular side portion 124 is 18mm-25mm. The height H of the annular side portion 124 can be, but is not limited to, 18mm, 18.5mm, 19mm, 19.5mm, 20mm, 20.5mm, 21mm, 21.5mm, 22mm, 22.5mm, 23mm, 23.5mm, 24mm, 24.5mm or 25mm, etc. In this way, the height H of the annular side portion 124 in this range can make the snow throwing cylinder 200 have a certain distance from the snow protection ring 120, which can effectively reduce the risk of the snow throwing cylinder 200 being frozen by the ice on the fuselage shell 110. In addition, the height H of the annular side portion 124 in this range can effectively avoid the center of gravity of the snow throwing cylinder 200 being too high, so that the center of gravity of the snow throwing cylinder 200 is stable, thereby helping to ensure that the snow throwing cylinder 200 is stably rotatably connected to the fuselage shell 110.

[0053] In the embodiment, the connecting portion 123 is integrally formed with the annular side portion 124, thereby facilitating to improve the strength of the connecting portion 123 and the annular side portion 124, and facilitating to reduce the assembly process of the connecting portion 123 and the annular side portion 124, and facilitating to quickly assemble the snow prevention ring 120 to the fuselage shell 110.

[0054] Referring to Figures 1 to 3 In some embodiments, the fuselage assembly 100 can further include an outer sealing member 130, the snow prevention ring 120 can include the connecting portion 123 and the annular side portion 124 connected together, and the annular side portion 124 can be located on the side of the connecting portion 123 away from the fuselage shell 110. The outer sealing member 130 can be located between the connecting portion 123 and the fuselage shell 110. The outer sealing member 130 can be selected in various manners, for example, the outer sealing member 130 can be a silica gel sealing member, or for example, the outer sealing member 130 can be a rubber sealing member. In this way, the outer sealing member 130 is connected between the snow prevention ring 120 and the fuselage shell 110, thereby effectively reducing the risk of impurities such as water, dust or sand entering the containing space 101 from the connecting portion 123 and the fuselage shell 110.

[0055] Referring to Figures 1 to 3 and Figure 7 In some embodiments, the snow prevention ring 120 can further include a plurality of fixing lugs 125, the plurality of fixing lugs 125 can be connected to the connecting portion 123, the plurality of fixing lugs 125 can be distributed around the outer periphery of the connecting portion 123 and spaced apart, and the plurality of fixing lugs 125 can be fixedly connected to the fuselage shell 110. The fixing lugs 125 can be connected to the fuselage assembly 100 by screws or rivets, so as to press the outer sealing member 130 between the connecting portion 123 and the fuselage shell 110. In this way, the plurality of fixing lugs 125 are spaced apart on the connecting portion 123, so that the snow prevention ring 120 can apply force to different positions of the outer sealing member 130 more evenly, thereby making the outer sealing member 130 bear force evenly, and further facilitating to improve the sealing performance of the outer sealing member 130 in sealing the connecting portion 123 and the fuselage shell 110.

[0056] Referring to Figure 2 , Figure 3 and Figure 5In some embodiments, the body assembly 100 further comprises a first inner seal 150 connected between the snow throwing cylinder 200 and the connecting member 140. The first inner seal 150 can be selected from various types, such as a silica gel seal, or a rubber seal. The connection between the snow throwing cylinder 200 and the connecting member 140 is sealed by the first inner seal 150, which effectively reduces the risk of water, dust, or sand entering the accommodation space 101 from the connection between the snow throwing cylinder 200 and the connecting member 140, thereby ensuring the normal rotation of the rotating component 300. The material of the first inner seal 150 is relatively soft, which helps to reduce the friction between the snow throwing cylinder 200 and the connecting member 140.

[0057] In some embodiments, the body assembly 100 further comprises a second inner seal 160 connected between the connecting member 140 and the inner layer shell 111. The second inner seal 160 can be selected from various types, such as a silica gel seal, or a rubber seal. The connection between the connecting member 140 and the inner layer shell 111 is sealed by the second inner seal 160, which effectively reduces the risk of water, dust, or sand entering the accommodation space 101 from the connection between the connecting member 140 and the inner layer shell 111, thereby ensuring the normal rotation of the rotating component 300.

[0058] Please refer to Figure 1 The snow removal device according to the embodiments of the present application can comprise a self-moving device and a snow removal device 10. The snow removal device 10 can be installed at the front of the self-moving device, so that the self-moving device carries the snow removal device 10 to remove snow. The specific structure of the snow removal device 10 can refer to the above embodiments. Since the snow removal device adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0059] The self-moving device can comprise a control assembly and a driving module.
