DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the present application, not all the implementation modes. Based on the implementation mode in the present application, all other implementation modes obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

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

[0030] See also Figure 1 The embodiment of the present application provides a snow removal device 10, which can be applied to snow removal equipment to remove snow from roads or courtyards. In the following embodiments, the application of the snow removal device 10 to snow removal equipment is mainly used as an example for description and introduction, and other situations requiring the snow removal device 10 can be implemented with reference.

[0031] See also Figures 1 to 3The snow removal device 10 may include a fuselage assembly 100 and a snow throwing barrel 200. The fuselage assembly 100 may include a fuselage shell 110 and a snow prevention ring 120. The snow prevention ring 120 is formed separately from the fuselage shell 110. The snow prevention ring 120 may be located above the fuselage shell 110. The snow prevention ring 120 may be installed above the fuselage shell 110. The side of the snow prevention ring 120 facing away from the fuselage shell 110 may have a connecting end 121. The fuselage assembly 100 may be provided with a accommodating space 101. The snow throwing barrel 200 is rotatably connected to the fuselage shell 110. The end of the snow throwing barrel 200 facing the fuselage shell 110 may be provided with an annular groove 201 connected to the accommodating space 101 and opening downward. At least a portion of the connecting end 121 may 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-proof ring 120 and the fuselage shell 110 can be manufactured separately, and the snow-proof ring 120 can be precision-machined so that the snow-proof ring 120 can better cooperate with the snow throwing tube 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 preset range, helping to reduce the risk of impurities such as water, dust or mud entering the accommodating space 101; the fuselage shell 110 can be roughly machined, which helps to reduce the manufacturing cost of the fuselage shell 110.

[0032] In addition, an annular groove 201 connected to the accommodating space 101 and opening downward is provided at one end of the snow throwing barrel 200 facing the fuselage shell 110, so that impurities such as water, dust or mud and sand are difficult to enter the accommodating space 101 through the annular groove 201, which helps to reduce the risk of impurities such as water, dust or mud and sand entering the accommodating space 101, thereby helping to ensure that the rotating component 300 installed in the accommodating space 101 can work normally.

[0033] Moreover, the snow-proof ring 120 is located between the fuselage shell 110 and the snow-throwing barrel 200, so that the snow-throwing barrel 200 has a certain distance from the fuselage shell 110, thereby preventing the snow accumulated on the fuselage shell 110 from freezing and freezing the snow-throwing barrel 200, thereby helping to ensure that the snow-throwing barrel 200 can rotate normally, and also helping to reduce the rotation resistance of the snow-throwing barrel 200. In addition, the snow-throwing barrel 200 has a certain distance from the fuselage shell 110, so that the snow-throwing barrel 200 is not easy to contact the snow accumulated on the fuselage shell 110, which helps to reduce the friction between the snow-throwing barrel 200 and the snow accumulated on the fuselage shell 110, thereby extending the service life of the snow-throwing barrel 200.

[0034] See also Figure 1The body shell 110 is the main frame of the snow removal device 10. The body shell 110 can be made of a solid material, for example, the body shell 110 can be made of aluminum alloy or hard plastic, so that the body shell 110 can provide stable supporting performance, thereby ensuring the overall rigidity and stability of the snow removal device 10.

[0035] See also Figure 1 and Figure 2 The fuselage shell 110 may 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 may be provided with a snow outlet 103 connected to the snow collecting space 102. The snow collecting space 102 is not connected to the accommodating space 101. The accommodating space 101 may be arranged around the snow outlet 103.

[0036] The snow removal device 10 may include an impeller assembly (not shown in the figure), which may be located in the snow collection space 102. The impeller assembly may include multiple centrifugal impellers, which may include multiple snow-clearing blades. The impeller assembly may be installed at the bottom of the snow removal device 10, and the impeller assembly may directly contact the accumulated snow. When the centrifugal impeller rotates at high speed, the accumulated snow rolled up by the centrifugal impeller is collected into the snow collection space 102 under the action of centrifugal force and the accumulated snow is thrown out from the snow outlet 103, and finally thrown to the designated location through the snow throwing barrel 200.

[0037] The fuselage shell 110 may further include a connecting member 140, which may be connected between the inner shell 111 and the snow throwing tube 200, and the connecting member 140 may be arranged around the snow outlet 103, and the connecting member 140 may be arranged opposite to and spaced from the snow protection ring 120. The number of the connecting members 140 may be multiple, such as Figure 3 As shown, the number of the connecting members 140 may be three, and the three connecting members 140 may be arranged in sequence along the axial direction of the snow throwing cylinder 200 to connect the inner shell 111 with the snow throwing cylinder 200 .

[0038] See also Figures 2 to 5 The connecting piece 140 , the snow-proof ring 120 , the inner shell 111 and the outer shell 112 enclose a receiving space 101 . The receiving space 101 is not connected to the snow collecting space 102 , and the receiving space 101 can be arranged around the snow outlet 103 .

[0039] See also Figure 2 and Figure 5 The snow removal device 10 may further include a rotating component 300, which may be installed in the accommodation space 101. The rotating component 300 may include components such as gears and bearings. The rotating component 300 may rotate under the action of a driving source to drive the snow throwing barrel 200 to rotate. The driving source may be a driving device such as an electric motor.

[0040] The outer contour of the snow throwing cylinder 200 can be roughly cylindrical, and the end of the snow throwing cylinder 200 away from the fuselage assembly 100 can be bent toward the fuselage assembly 100, so that the snow throwing cylinder 200 can better guide the snow to be thrown. 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 to a designated place.

[0041] See also Figure 1 and Figure 3 In some embodiments, the snow thrower 200 may include a snow thrower 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 may be connected to the snow thrower body 210. The first annular side wall 220, the second annular side wall 230 and the snow thrower body 210 may be combined to form an annular groove 201. The first annular side wall 220 and the second annular side wall 230 may be located on both sides of the connecting end 121, respectively. The first annular side wall 220 and the outer periphery of the connecting end 121 may be arranged relative to each other.

[0042] A first annular slope 221 may be provided on the outer periphery of the first annular side wall 220 toward the connecting end 121. The first annular slope 221 is inclined downwardly from the second annular side wall 230 toward the first annular side wall 220. A second annular slope 122 is provided on the outer periphery of the connecting end 121. The second annular slope 122 is inclined downwardly from the second annular side wall 230 toward the outer periphery of the connecting end 121. The second annular slope 122 is opposite to and spaced from the first annular slope 221.

[0043] Specifically, since the first annular slope 221 is inclined downward from the second annular side wall 230 to the first annular side wall 220, and the second annular slope 122 is inclined downward from the second annular side wall 230 to the outer periphery of the connecting end 121, 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 roughly the same as the outer diameter of the connecting end 121, so that the outer diameter of the snow throwing barrel 200 and the outer diameter of the snow protection ring 120 can be made smaller, so that the structure of the snow protection ring 120 and the snow throwing barrel 200 is more compact and the cost is lower.

[0044] In addition, the first annular slope 221 slopes 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, which not only allows the first annular side wall 220 to avoid the connecting end 121, but also enables the first annular side wall 220 to have higher strength.

[0045] Moreover, the second annular slope 122 is inclined downward from the second annular side wall 230 toward the outer periphery of the connecting end 121, and the thickness of the connecting end 121 gradually increases from top to bottom, which not only allows the connecting end 121 to avoid the first annular side wall 220, but also enables the connecting end 121 to have better strength.

[0046] In some embodiments, the inclination direction of the first annular slope 221 is consistent with the inclination direction of the second annular slope 122. Specifically, the inclination direction of the first annular slope 221 is parallel to the inclination direction of the second annular slope 122; or, the inclination direction of the first annular slope 221 is substantially parallel to the inclination direction 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 relatively uniform, thereby helping to reduce the risk of interference between the snow throwing tube 200 and the snow ring 120. In addition, when a lot of debris accumulates on the first annular slope 221 and the second annular slope 122, it is also convenient for the operator to clear 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. Thus, the first annular sidewall 220 has a greater height, which helps the first annular sidewall 220 to cover the opening of the annular groove 201; the second annular sidewall 230 has a smaller height, which helps the fuselage assembly 100 to form a larger accommodating space 101 and prevents the second annular sidewall 230 from interfering with the rotating component 300.

[0048] See also Figure 3 In some embodiments, the gap L between the groove wall of the annular groove 201 and the connecting end 121 is 2 mm to 6 mm. The gap L between the groove wall of the annular groove 201 and the connecting end 121 may be, but is not limited to, 2 mm, 2.3 mm, 2.5 mm, 2.8 mm, 3 mm, 3.3 mm, 3.5 mm, 3.8 mm, 4 mm, 4.3 mm, 4.5 mm, 4.85 mm, 5.3 mm, 5.5 mm, 5.8 mm or 6 mm. In this way, the gap L between the groove wall of the annular groove 201 and the connecting end 121 is within this range, which helps to reduce the risk of interference between the snow throwing tube 200 and the snow protection ring 120, thereby helping to reduce the friction between the snow throwing tube 200 and the snow protection ring 120, and also helps to prevent water, dust or mud from entering the accommodation space 101 due to the excessive gap L.

[0049] See also Figure 2 and Figure 3In some embodiments, the snow thrower 200 may include a snow thrower body 240 and a protective sleeve 250. The snow thrower body 240 is rotatably connected to the fuselage shell 110. The protective sleeve 250 may be sleeved on one end of the snow thrower body 240 close to the fuselage assembly 100. An annular groove 201 may be provided on the end of the protective sleeve 250 facing the fuselage assembly 100. The snow thrower body 240 and the protective sleeve 250 are formed separately.

[0050] Specifically, since the outer periphery of the end of the snow throwing barrel 200 close to the fuselage shell 110 is easily rubbed against the snow accumulated on the fuselage shell 110, the outer periphery of the end of the snow throwing barrel 200 close to the fuselage shell 110 is easily worn. Therefore, the protective sleeve 250 is sleeved on the outer periphery of the end of the snow throwing barrel body 240 close to the fuselage assembly 100, and the snow throwing barrel body 240 and the protective sleeve 250 are separately formed, which is helpful for replacing the snow throwing barrel 200 and can also avoid replacing the entire snow throwing barrel 200, thereby helping to reduce maintenance costs.

[0051] In addition, the snow slinger body 240 and the protective sleeve 250 are formed separately, which also helps to remove the protective sleeve 250 from the snow slinger body 210 to clean the impurities in the annular groove 201, making the snow slinger 200 easy to maintain. Moreover, the snow slinger body 240 and the protective sleeve 250 are formed separately, which also helps to manufacture the snow slinger 200 and has a low cost.

[0052] See also Figures 5 to 7 In some embodiments, the snow ring 120 may include a connecting portion 123 and an annular side portion 124 connected to each other. The connecting portion 123 may be connected to and accommodated in the fuselage shell 110. For example, the fuselage shell 110 is provided with a slot for accommodating the connecting portion 123. The annular side portion 124 may be convexly arranged above the fuselage shell 110. The height H of the annular side portion 124 is 18 mm to 25 mm. The height H of the annular side portion 124 may be, but is not limited to, 18 mm, 18.5 mm, 19 mm, 19.5 mm, 20 mm, 20.5 mm, 21 mm, 21.5 mm, 22 mm, 22.5 mm, 23 mm, 23.5 mm, 24 mm, 24.5 mm or 25 mm, etc. Thus, when the height H of the annular side portion 124 is within this range, the snow throwing barrel 200 can be kept at a certain distance from the snow protection ring 120, which can effectively reduce the risk of snow accumulation freezing on the fuselage shell 110 and freezing the snow throwing barrel 200. In addition, when the height H of the annular side portion 124 is within this range, the center of gravity of the snow throwing barrel 200 can be effectively prevented from being too high, so that the center of gravity of the snow throwing barrel 200 is stable, thereby helping to ensure that the snow throwing barrel 200 is stably rotatably connected to the fuselage shell 110.

[0053] In this embodiment, the connecting portion 123 and the annular side portion 124 are integrally formed, which helps to improve the strength of the connection between the connecting portion 123 and the annular side portion 124, and also helps to reduce the assembly process of the connecting portion 123 and the annular side portion 124, making it easier for the snow ring 120 to be quickly assembled to the fuselage shell 110.

[0054] See also Figures 1 to 3 In some embodiments, the fuselage assembly 100 may further include an outer seal 130, and the snow ring 120 may include a connecting portion 123 and an annular side portion 124 connected to each other, and the annular side wall 124 may be located on the side of the connecting portion 123 away from the fuselage shell 110. The outer seal 130 may be located between the connecting portion 123 and the fuselage shell 110. There are many options for the outer seal 130, for example, the outer seal 130 may be a silicone seal; for another example, the outer seal 130 may be a rubber seal. In this way, the outer seal 130 is connected between the snow ring 120 and the fuselage shell 110, thereby effectively reducing the risk of impurities such as water, dust or mud and sand entering the accommodation space 101 from the connection between the snow ring 120 and the fuselage shell 110.

[0055] See also Figures 1 to 3 as well as Figure 7 In some embodiments, the snow ring 120 may further include a plurality of fixing ears 125, which may be connected to the connection portion 123, which may surround the outer periphery of the connection portion 123 and be spaced apart, and which may be fixedly connected to the fuselage shell 110, wherein the fixing ears 125 may be connected to the fuselage assembly 100 by screws or rivets, so as to press the outer seal 130 between the connection portion 123 and the fuselage shell 110. In this way, the plurality of fixing ears 125 are spaced apart in the connection portion 123, so that the force exerted by the snow ring 120 on different positions of the seal 130 is more uniform, so that the outer seal 130 is subjected to uniform force, which further helps to improve the sealing performance of the connection between the outer seal 130 and the fuselage shell 110.

[0056] See also Figure 2 , Figure 3 and Figure 5In some embodiments, the fuselage assembly 100 further includes a first inner seal 150, and the first inner seal 150 is connected between the snow throwing barrel 200 and the connecting member 140. There are multiple options for the first inner seal 150, for example, the first inner seal 150 may be a silicone seal; for another example, the first inner seal 150 may be a rubber seal. In this way, the first inner seal 150 connected between the snow throwing barrel 200 and the connecting member 140 helps to improve the sealing of the connection between the snow throwing barrel 200 and the connecting member 140, thereby effectively reducing the risk of impurities such as water, dust or mud and sand entering the accommodating space 101 from the connection between the snow throwing barrel 200 and the connecting member 140, thereby helping to ensure the normal rotation of the rotating component 300, and the manufacturing material of the first inner seal 150 is relatively soft, which helps to reduce the friction between the snow throwing barrel 200 and the connecting member 140.

[0057] In some embodiments, the fuselage assembly 100 further includes a second inner seal 160, which is connected between the connector 140 and the inner shell 111. There are multiple options for the second inner seal 160, for example, the second inner seal 160 may be a silicone seal; for another example, the second inner seal 160 may be a rubber seal. In this way, the second inner seal 160 connected between the connector 140 and the inner shell 111 helps to improve the sealing of the connection between the connector 140 and the inner shell 111, thereby effectively reducing the risk of impurities such as water, dust or mud entering the accommodating space 101 from the connection between the connector 140 and the inner shell 111, thereby helping to ensure the normal rotation of the rotating component 300.

[0058] See also Figure 1 The embodiment of the present application also proposes a snow removal device, which may include a self-propelled device and a snow removal device 10. The snow removal device 10 may be installed at the front of the self-propelled device so that the self-propelled device carries the snow removal device 10 to remove snow. The specific structure of the snow removal device 10 may refer to the above embodiment. Since the snow removal device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0059] The self-moving device may include a control component and a drive module, the control component may include components such as a circuit board, and the control component may control the drive module to move. The drive module may be used to drive the snow removal device 10 to move. For example, the drive module may include a drive wheel, and the number of the drive wheels may be multiple.
