[0029] Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 a snow sweeping device 100 provided by the embodiments of the present application.

[0030] In the embodiments of the present application, the snow sweeping device 100 can include a traveling device 101 and a snow sweeping device 102. The traveling device 101 can be provided with a tire type or track type traveling mechanism, and can be provided with a prime mover. The prime mover can drive the traveling mechanism to work, so that the traveling mechanism can travel on the ground; the prime mover can also provide power and / or energy for the snow sweeping device 102 and other components of the snow sweeping device 100, so that the snow sweeping device 100 can realize sweeping of accumulated snow during traveling. The prime mover can be an internal combustion engine or an electric motor.

[0031] It can be understood that the length direction, the width direction and the height direction of the snow sweeping device 100 can be defined as the first direction, the second direction and the vertical direction respectively. For example, the first direction can be the X direction and the opposite direction thereof as shown in Figure 1 and Figure 2 , the second direction can be the Y direction and the opposite direction thereof as shown in Figure 1 and Figure 2 , and the vertical direction can be the Z direction and the opposite direction thereof as shown in Figure 1 and Figure 2 .

[0032] The driving direction of the traveling device 101 when driving in a straight line can coincide with the first direction.

[0033] In some embodiments, the snow sweeping device 100 can further comprise a lifting device 103. The lifting device 103 can be mounted on the traveling device 101 and can be connected with the snow sweeping device 102. The lifting device 103 can drive the snow sweeping device 102 to move in the vertical direction so that the snow sweeping device 102 moves away from or approaches the ground by rising or falling. As the height of the snow sweeping device 102 changes, the snow sweeping device 102 can sweep the snow located at different heights to solve the defect that the snow sweeping device 102 is difficult to sweep the snow when the thickness of the snow is higher than the height of the snow sweeping device 102.

[0034] The lifting device 103 can comprise a connecting mechanism and a lifting driving member (not shown in the figure). The lifting driving member can be accommodated in the traveling device 101 or fixedly mounted on the traveling device 101. The connecting mechanism can be fixedly connected with the lifting driving member and can be connected with the snow sweeping device 102. The number of the connecting mechanisms is two and they are respectively located on both sides of the snow sweeping device 102 in the second direction. The lifting driving member can drive the connecting mechanism to move, so that the snow sweeping device 102 moves synchronously in the vertical direction.

[0035] In the embodiments of the present application, the specific position of the lifting driving member is not specifically limited. For example, the traveling device 101 can be provided with a mounting space and the traveling driving member can be located in the mounting space.

[0036] In the embodiments of the present application, the fixing mode when fixedly mounted and fixedly connected is not specifically limited. For example, the fixing mode can include, but is not limited to, bolt fixing, welding fixing, interference fit fixing, integral forming fixing, etc.

[0037] Please refer to Figure 3In some embodiments, each connecting mechanism can include a plurality of connecting arms 1031. The plurality of connecting arms 1031 can be spaced apart in a direction perpendicular to the second direction. One end of each connecting arm 1031 is rotatably connected to the traveling device 101, and the other end is rotatably connected to the snow removing device 102. The lifting driving member can drive at least one connecting arm 1031 to rotate, so as to drive the snow removing device 102 to move in the vertical direction.

[0038] It can be understood that the rotatable connection can be achieved by a rotatable connecting member, which is a connecting mode that allows two components to rotate relative to each other. In the embodiments of the present application, the type of the rotatable connecting member is not specifically limited. For example, the rotatable connecting member 22 can be, but is not limited to, a pin shaft, a bearing, a hinge, etc.

[0039] In the embodiments of the present application, the number of connecting arms 1031 in each connecting mechanism is not specifically limited. For example, in each connecting mechanism, the number of connecting arms 1031 can be two.

[0040] In the embodiments of the present application, the type of the lifting driving member is not specifically limited. For example, the lifting driving member can be, but is not limited to, a speed-reducing motor.

[0041] Please refer to Figure 4 and Figure 5 In some embodiments, the snow removing device 102 can include a snow collecting mechanism 10 and a snow removing mechanism.

[0042] The snow collecting mechanism 10 can be rotatably connected to the plurality of connecting arms 1031. A snow collecting space 111 can be formed in the snow collecting mechanism 10, and the first side of the snow collecting mechanism 10 in the first direction and the bottom of the snow collecting mechanism 10 in the vertical direction are both open, so that the snow collecting space 111 is in communication with the outside through the openings on the snow collecting mechanism 10.

[0043] The snow removing mechanism can include a snow removing assembly 20 and a snow removing driving member (not shown in the figure). The snow removing assembly 20 can be accommodated in the snow collecting space 111, and the snow removing assembly 20 is rotatably connected to the snow collecting mechanism 10. The snow removing driving member can be fixedly connected to the snow removing driving member, and can be fixedly installed on the snow collecting mechanism 10. The snow removing driving member can drive the snow removing assembly 20 to rotate, the snow removing assembly 20 can contact the snow on the ground, and move the snow in the snow collecting space 111 by rotating. The snow collecting mechanism 10 can further drive the snow to move, and throw the snow to a predetermined position.

[0044] It can be understood that the snow removing driving member can be an electric or pneumatic member with a rotating driving function. In the embodiments of the present application, the type of the snow removing driving member is not specifically limited. For example, the snow removing driving member can be, but is not limited to, a speed-reducing motor, a rotary air cylinder, etc.

[0045] In embodiments of the present application, the installation position of the snow sweeping driving member is not particularly limited. For example, the snow sweeping driving member can be installed in the snow collecting space 111. For another example, the snow sweeping driving member can be installed outside the snow collecting mechanism 10.

[0046] It can be understood that the first direction can have a first side and a second side arranged oppositely. The direction in which the second side faces the first side can be the advancing direction of the snow sweeping device 100 when it travels straight, and the direction in which the first side faces the second side can be the retreating direction of the snow sweeping device 100 when it travels straight.

[0047] In some embodiments, the snow sweeping assembly 20 can include a first spiral plate 21 and a second spiral plate 22. The first spiral plate 21 and the second spiral plate 22 extend spirally in opposite spiral directions, respectively. The first spiral plate 21 and the second spiral plate 22 can be arranged adjacently in the second direction, and the first spiral plate 21 and the second spiral plate 22 are coaxial. One end of the first spiral plate 21 facing the second spiral plate 22 is fixedly connected to one end of the second spiral plate 22 facing the first spiral plate 21, forming a two-sided structure in the second direction, each side of which is provided with a snow sweeping blade spirally extending in the opposite spiral direction.

[0048] The position at which the first spiral plate 21 and the second spiral plate 22 are connected is located in the middle of the snow sweeping assembly 20 in the second direction, and a guide groove 23 is formed at the position at which the first spiral plate 21 and the second spiral plate 22 are connected. The structure of the part of the first spiral plate 21 close to the second spiral plate 22 cooperates with the structure of the part of the second spiral plate 22 close to the first spiral plate 21 to form the inner wall of the guide groove 23. The guide groove 23 gradually shrinks along the rotation direction of the snow sweeping assembly 20.

[0049] It can be understood that when the snow sweeping assembly 20 rotates, the first spiral plate 21 and the second spiral plate 22 rotate in the same circumferential direction, so as to drive the accumulated snow close to the guide groove 23. The inner wall of the guide groove 23 can be in contact with the accumulated snow. The centrifugal force when the snow sweeping assembly 20 rotates can drive the accumulated snow to enter the inner wall of the snow collecting space 111 and move away from the first side of the snow collecting mechanism 10; the inner wall of the guide groove 23 can guide the accumulated snow to move to the middle position of the snow collecting space 111 in the second direction.

[0050] In some embodiments, the peripheral wall of the first spiral plate 21 and the peripheral wall of the second spiral plate 22 are each provided with a first tooth pattern 24, and the inner side of the first spiral plate 21 and the inner side of the second spiral plate 22 are each provided with a second tooth pattern 25, and the first tooth pattern 24 and the second tooth pattern 25 are arranged in a spaced manner. The first tooth pattern 24 and the second tooth pattern 25 can each form a plurality of tooth grooves capable of collecting snow.

[0051] Compared with the snow sweeping blade with smooth surface, the first and second tooth patterns 24 and 25 can increase the adhesion between the snow sweeping assembly 20 and the snow, improve the efficiency of the snow sweeping assembly 20 in rotating to drive the snow into the snow collecting space 111, and improve the efficiency of the snow sweeping device 100 in sweeping the snow.

[0052] Please refer to Figure 6 and Figure 7 In some embodiments, the snow collecting mechanism 10 can include a snow collecting assembly and a snow throwing assembly. The snow collecting assembly can include a snow collecting cover 11, an impeller 12, and a snow feeding driving member (not shown).

[0053] The first side of the snow collecting cover 11 in the first direction can be open, and the bottom can be open. The snow collecting space 111 is arranged in the snow collecting cover 11, and the snow collecting space 111 is in communication with the outside through the opening of the first side of the snow collecting cover 11 in the first direction and the opening of the bottom. The snow sweeping assembly 20 is rotationally connected to the snow collecting cover 11, and the snow sweeping driving member is installed on the snow collecting cover 11. The second side of the snow collecting cover 11 in the first direction can be provided with a snow feeding cavity 112 and a snow throwing passage 113. The snow feeding cavity 112 is located on the inner wall of the second side of the snow collecting space 111 in the first direction, and is located in the middle of the snow collecting cover 11 in the second direction. The snow feeding cavity 112 is in communication with the snow collecting space 111. The snow feeding cavity 112 can be arranged correspondingly with the guide groove 23. The snow throwing passage 113 can be in communication with the inner wall of the snow feeding cavity 112, and the snow throwing passage 113 can extend to the top of the snow collecting cover 11 along the vertical direction or a direction with an acute angle with the vertical direction. The impeller 12 can be located in the snow feeding cavity 112, and the impeller 12 can be connected with the snow feeding driving member. The snow feeding driving member can be installed on the snow collecting cover 11. The snow feeding driving member can drive the impeller 12 to rotate, and the impeller 12 can contact the snow and drive the snow to move from the snow feeding cavity 112 to the snow throwing passage 113 through the centrifugal force generated by the rotation. The snow throwing passage 113 can be in communication with the snow throwing assembly, and the snow throwing assembly can receive the snow from the snow throwing passage 113 and throw the snow to a predetermined position.

[0054] It can be understood that the inner wall of the guide groove 23 can guide the snow to move towards the snow feeding cavity 112. After the snow entering the snow feeding cavity 112 contacts the impeller 12, the snow can be driven by the rotating impeller 12 to approach the communication position of the snow throwing passage 113 and the snow feeding cavity 112, and then be thrown to the predetermined position through the snow throwing passage 113 and the snow throwing assembly.

[0055] The snow feeding cavity 112 can have a circular ring-shaped inner wall, and the axial direction of the circular ring-shaped inner wall can coincide with the axial direction of the impeller 12. Under the driving of the impeller 12, part of the snow deviating from the snow throwing passage 113 can be collected in the snow feeding cavity 112 and move in the direction around the snow feeding cavity 112, and finally move to the position where the snow throwing passage 113 is in communication with the snow feeding cavity 112 to enter the snow throwing passage 113.

[0056] In embodiments of the present application, the type of the snow intake driving member is not particularly limited. For example, the snow intake driving member can be, but is not limited to, a motor.

[0057] In embodiments of the present application, the installation position of the snow intake driving member is not particularly limited. For example, the snow intake driving member can be located in the snow intake cavity 112. For another example, the snow intake driving member can be installed on the outside of the snow collecting cover 11.

[0058] In some embodiments, the snow collecting assembly can further include two side frames 13. The two side frames 13 can extend in the second direction and can be fixedly connected to the top of the snow collecting cover 11. The two side frames 13 can be connected with two connecting mechanisms respectively, and the connecting arm 1031 in each connecting mechanism is rotationally connected to the corresponding side frame 13 to realize the connection with the snow collecting mechanism 10.

[0059] In some embodiments, the snow throwing assembly can include a snow throwing pipe 14 and a first adjusting unit 15.

[0060] The snow throwing pipe 14 is rotationally connected to the top of the snow collecting cover 11, and the snow throwing pipe 14 can extend in the vertical direction. The snow throwing pipe 14 is a hollow pipe body, the snow throwing pipe 14 can be in communication with the snow throwing passage 113, and the top of the snow throwing pipe 14 can be provided with a snow throwing opening 141. The snow in the snow collecting space 111 can enter the snow throwing passage 113 through the driving of the impeller 12, and then be thrown out through the snow throwing pipe 14 and the snow throwing opening 141.

[0061] The peripheral portion of the snow throwing pipe 14 can be fixedly connected with a first transmission member 142. The first adjusting unit 15 can include a turning driving member 151 and a second transmission member 152. The second transmission member 152 can be fixedly installed on the top of the snow collecting cover 11 and can be fixedly connected with the second transmission member 152. The second transmission member 152 can cooperate with the first transmission member 142, so that the driving force generated by the turning driving member 151 can be transmitted to the snow throwing pipe 14. The turning driving member 151 can drive the second transmission member 152 to move, so that the snow throwing pipe 14 and the first transmission member 142 are synchronously rotated.

[0062] It can be understood that the snow throwing opening 141 can be obliquely provided. The rotation of the snow throwing pipe 14 can adjust the snow throwing direction of the snow sweeping device 100, so that the swept snow can be thrown towards the preset position determined by the worker or user.

[0063] In embodiments of the present application, the type of the first transmission member 142 and the second transmission member 152 is not particularly limited. For example, the first transmission member 142 and the second transmission member 152 can both be gears, the first transmission member 142 is engaged with the second transmission member 152, and the turning driving member 151 can drive the second turning member to rotate.

[0064] For another example, the first transmission member 142 can be a worm gear, the second transmission member 152 can be a worm, the first transmission member 142 meshes with the second transmission member 152, and the steering driving member 151 can drive the second steering member to rotate.

[0065] For another example, the first transmission member 142 can be a gear, the second transmission member 152 can be a rack, the first transmission member 142 meshes with the second transmission member 152, and the steering driving member 151 can drive the second transmission member 152 to move linearly.

[0066] In the embodiments of the present application, the type of the steering driving member 151 is not specifically limited. For example, when the first transmission member 142 and the second transmission member 152 are both gears, or the first transmission member 142 is a worm gear and the second transmission member 152 is a worm, the steering driving member 151 can be a motor. For another example, when the first transmission member 142 is a gear and the second transmission member 152 is a rack, the steering driving member 151 can be a linear motor or a cylinder.

[0067] In some embodiments, the snow throwing assembly can further include a second adjusting unit 16. The second adjusting unit 16 can include a guide cover 161 and a guide driving member 162. The guide cover 161 is rotationally connected to the top of the snow throwing pipe 14, so as to at least partially shield the snow throwing opening 141 from the top. The guide cover 161 can be provided with a guide wall 1611, which is arc-shaped or inclined, and is arranged in correspondence with the snow throwing opening 141. The snow removed from the snow throwing opening 141 can contact the guide wall 1611 and continue to move along the extension direction of the guide wall 1611, so as to be thrown to a preset position. The guide driving member 162 can be mounted on the outer side of the snow throwing pipe 14 and connected with the guide cover 161. The guide driving member 162 can drive the guide cover 161 to rotate, so as to adjust the inclination angle of the guide cover 161, and further adjust the extension direction of the guide wall 1611.

[0068] In the embodiments of the present application, the type of the guide driving member 162 is not specifically limited.

[0069] For example, the guide driving member 162 can have a driving function of linear movement. The top of the guide cover 161 can be fixedly connected with an extension part 1612. The rotor of the guide driving member 162 is rotationally connected to the extension part 1612, so as to be connected with the guide cover 161; the stator of the guide driving member 162 is rotationally connected to the peripheral wall of the snow throwing pipe 14. The guide driving member 162 can drive the extension part 1612 to move in the vertical direction, and the guide cover 161 can synchronously rotate relative to the snow throwing pipe 14; in this process, the guide driving member 162 can synchronously rotate relative to the snow throwing pipe 14.

[0070] For example, the guide driving member 162 can be, but is not limited to, a linear motor, a cylinder, etc.

[0071] It can be understood that the rotation of the guide cover 161 can adjust the extension direction of the guide wall 1611, so as to adjust the height of the snow from the throwing of the guide wall 1611, and the higher the height of the snow from the throwing, the distance of the snow in the horizontal direction can be increased synchronously, so as to adjust the distance of the snow throwing in the horizontal direction by rotating the guide cover 161 of the shell. The staff can adjust the orientation and distance of the snow throwing by the cooperation of the steering driving member 151 and the guide driving member 162 according to the positional relationship between the preset position and the snow removing device 100, so that the snow thrown from the snow throwing port 141 can fall on the preset position. In this way, the convenience of the snow removing device 100 after cleaning the snow can be improved.

[0072] In some embodiments, the snow removing device 102 comprises a guard plate 30 and a scraper 40.

[0073] The number of the guard plate 30 can be two, and the two guard plates 30 can be arranged in the second direction and fixedly installed on the bottom of the snow collecting cover 11. The scraper 40 can be located between the two guard plates 30, and the scraper 40 can extend in the second direction.

[0074] The guard plate 30 and the scraper 40 are both fixedly connected to the bottom of the snow collecting cover 11. The guard plate 30 and the scraper 40 can both protrude from the bottom of the snow collecting cover 11 in the vertical direction and can both abut against the ground.

Then the lifting driving member can drive the connecting arm 1031 to rotate reversely, so as to lower the snow sweeping device 102, and the snow sweeping device 102 can continue to sweep the snow on the ground. In this way, the sweeping effect of the snow sweeping device 100 on the snow at a high place can be improved, and the reliability of the snow sweeping device 100 and the universality of the use scene of the snow sweeping device 100 can be improved.

[0077] When the snow sweeping device 102 sweeps the snow, the rotation of the snow sweeping assembly 20 can make the snow enter the guide groove 23, and enter the snow collecting space 111 and the snow entering cavity 112 through the guidance of the inner wall of the guide groove 23. The snow in the snow entering cavity 112 can enter in sequence through the snow throwing channel 113, the snow throwing pipe 14 and the snow throwing opening 141 by the driving of the impeller 12, and finally move out from the snow throwing opening 141; the snow moved out from the snow throwing opening 141 can abut against the guide wall 1611, and be thrown to a preset position along the inclined direction of the guide wall 1611. Through the cooperation of the turning driving member 151 and the guide driving member 162, the snow throwing pipe 14 and the guide cover 161 can both rotate, so that the snow throwing direction and distance can be adjusted according to the positional relationship between the preset position and the snow sweeping device 100, and the convenience and accuracy of throwing the snow after the snow sweeping device 100 sweeps the snow can be improved.
