[0027] like Figures 1 to 6 As shown, a snow sweeping device comprises:

[0028] The body 100 includes a rotatably connected guide plate 200, and the guide plate 200 has a first rotation position and a second rotation position relative to the body 100;

[0029] A pedal assembly is operably arranged on a side of the main body 100 away from the guide plate 200 and forms a linkage with the guide plate 200, wherein the pedal assembly has a first state and a second state, and the pedal assembly can switch between the first state and the second state. When the pedal assembly is in the first state, the guide plate 200 is in a first rotation position, and when the pedal assembly is in the second state, the guide plate 200 is in a second rotation position. By switching the pedal assembly between the first state and the second state, the guide plate 200 can be switched between the first rotation position and the second rotation position, thereby realizing the angle adjustment of the guide plate 200; the user does not need to bend over to adjust manually, and the snow discharge angle can be adjusted only by stepping on the foot, which greatly improves the convenience of user operation and is more humane than the prior art.

[0030] Specifically, if Figures 1 to 6 As shown, in this embodiment, the main body 100 includes a first accommodating chamber 110 and a second accommodating chamber 120 that are adjacent to each other, and a partition 130 is provided between the first accommodating chamber 110 and the second accommodating chamber 120 to ensure the independence of the snow-clearing space and the control space to avoid damage to the transmission structure 400.

[0031] In this embodiment, the guide plate 200 is located in the first accommodating chamber 110 and has a second rotating shaft 210 that passes through the partition 130 and is connected to the transmission structure 400. The pedal structure 300 is located in the second accommodating chamber 120, and the pedal 310 of the pedal structure 300 extends out of the second accommodating chamber 120 so that the user can step on it to adjust the direction of the guide plate 200, thereby adjusting the snow discharge angle.

[0032] In this embodiment, the second accommodating cavity 120 is further provided with a handle 700 extending in a direction away from the main body 100 for a user to hold.

[0033] like Figures 2 to 5As shown, in order to realize the linkage between the guide plate 200 and the pedal assembly, in the present embodiment, the pedal assembly includes a pedal structure 300 and a transmission structure 400 located on the right side of the main body 100, wherein the transmission structure 400 is located on the side of the partition 130 away from the first accommodating chamber 110, one end of which is connected to the pedal structure 300, and the other end is connected to the second rotating shaft 210 of the guide plate 200. When the pedal structure 300 is displaced relative to the main body 100 by force and switches between the first state and the second state, the transmission structure 400 rotates forward or reverse synchronously and drives the guide plate 200 to be in the first rotation position and the second rotation position relative to the main body 100, so that the pedal structure 300 is linked with the guide plate 200, thereby realizing the adjustment of the direction of the guide plate 200.

[0034] Specifically, in this embodiment, the transmission structure 400 includes a first transmission member 410 connected to the pedal structure 300, and a second transmission member 420 connected to the guide plate 200, and the first transmission member 410 is meshed with the second transmission member 420. When the pedal structure 300 is subjected to force to move vertically up and down relative to the main body 100, the first transmission member 410 rotates forward or reversely, and drives the second transmission member 420 meshed therewith to rotate forward or reversely, so that the guide plate 200 swings left and right relative to the main body 100, thereby adjusting the snow discharge angle.

[0035] It is worth noting that, in the present embodiment, the first rotation position and the second rotation position are left and right rotation positions of the guide plate 200, and the first state and the second state are the states of stepping on the pedal to move up or down.

[0036] The first transmission member 410 and the second transmission member 420 are cylindrical structures or gear structures with pulley teeth. Preferably, in this embodiment, the first transmission member 410 and the second transmission member 420 are cylindrical structures with pulley teeth, and the cylindrical axis has a clamping portion that is clamped with the second rotating shaft 210 or the first rotating shaft 320.

[0037] In order to make the transmission structure 400 more compact, in the present embodiment, a third transmission member 430 is further arranged between the first transmission member 410 and the second transmission member 420. One side of the third transmission member 430 is meshed and connected with the first transmission member 410, and the other side is meshed and connected with the second transmission member 420 to realize multi-stage transmission, thereby making the connection between the various components of the transmission structure 400 more compact and effectively reducing the installation space.

[0038] Preferably, in this embodiment, the third transmission member 430 has a first gear tooth 431 and a second gear tooth 432 with different directions, and the first gear tooth 431 and the second gear tooth 432 are staggered to avoid interference between the first gear tooth 431 and the second gear tooth 432 during transmission, wherein the first gear tooth 431 is vertically arranged and meshed with the second transmission member 420, and the second gear tooth 432 is obliquely arranged and meshed with the first transmission member 410, thereby realizing the transmission of different movement directions of the pedal structure 300 and the guide plate 200.

[0039] In order to protect the transmission structure 400, in the present embodiment, a protective shell 440 is further provided on the outside of the transmission structure 400. On the one hand, it can prevent dust and debris from entering the gear teeth, and can prevent other devices from colliding with it, thereby effectively ensuring the working environment of the transmission structure 400, thereby increasing the service life of the transmission structure 400; on the other hand, it can also prevent the lubricating oil on the gear teeth from leaking, effectively ensuring the cleanliness of the inside of the snow-clearing device.

[0040] Preferably, in order to further improve the stability of the transmission structure 400, the partition 130 is also provided with a plurality of ribs 132 that are engaged with the first transmission member 410 and the third transmission member 430 on the side facing the protective shell 440, and the ribs 132 can also reduce the friction between the first transmission member 410 and the third transmission member 430 and the surface of the partition 130 during rotation.

[0041] In this embodiment, the pedal structure 300 includes a foot pedal 310, and one end of the foot pedal 310 close to the transmission structure 400 is connected to the first transmission member 410 via a first rotating shaft 320, and the one end of the first rotating shaft 320 away from the first transmission member 410 is rotatably connected to the fixed structure 800 on the right inner wall of the main body 100. When the foot pedal 310 is displaced vertically relative to the main body 100 under the action of human pedaling, the first rotating shaft 320 rotates along its own axis and drives the first transmission member 410 to rotate forward or reverse, thereby realizing the input of driving force. Compared with the prior art, it does not require the user to bend over and adjust manually, and the direction of the guide plate 200 can be adjusted by the user only stepping on the foot pedal 310 when standing.

[0042] In this embodiment, in order to further ensure the stability of the first rotating shaft 320, a fixed structure 800 for accommodating the first rotating shaft 320 is provided at the axis center of the third transmission member 430, and the first rotating shaft 320 forms a rotatable connection with the fixed structure 800, so that there are force points at both ends of the first rotating shaft 320, thereby effectively ensuring the stability of the movement of the first rotating shaft 320.

[0043] In this embodiment, the pedal 310 extends along a direction close to the first rotating shaft 320 to form a connecting rod 330. The end of the connecting rod 330 away from the pedal 310 is perpendicularly arranged to the first rotating shaft 320 and is fixedly connected to the first rotating shaft 320 so that the pedal 310 can extend out of the second accommodating cavity 120.

[0044] To achieve automatic resetting of the connecting rod 330, in the present embodiment, the connecting rod 330 is connected to the inner wall of the main body 100 via an elastic member 340. When the connecting rod 330 moves downward as the foot pedal 310 is pressed downward, the elastic member 340 is stretched. Therefore, when the foot pedal 310 loses pressure, the elastic member 340 drives the connecting rod 330 to move upward through its own contraction force. On the one hand, the automatic resetting of the connecting rod 330 can be achieved, so that the transmission structure 400 rotates in the opposite direction, driving the guide plate 200 to swing to the initial position; on the other hand, the connecting rod 330 can be more securely inserted into the fixing groove 520, effectively preventing the connecting rod 330 from sliding out of the fixing groove 520 in the absence of external force, thereby ensuring the stability of the connecting rod 330.

[0045] Preferably, in this embodiment, the elastic member 340 is a spring, one end of which is detachably connected to the inner wall of the body 100 , and the other end of which is detachably connected to the connecting rod 330 , which effectively ensures the convenience of replacing the elastic member 340 .

[0046] In this embodiment, an adjustment plate 500 is provided on the side of the main body 100 close to the pedal structure 300. The adjustment plate 500 is detachably connected to the main body 100 and is connected to the second accommodating chamber 120. The adjustment plate 500 has a movable groove 510 and at least two fixed grooves 520 connected to the movable groove 510, wherein the connecting rod 330 passes through the adjustment plate 500 and switches between different fixed grooves 520 through the movable groove 510, thereby realizing the adjustment of the moving stroke of the connecting rod 330, thereby realizing the fine adjustment of the angle of the guide plate 200.

[0047] Preferably, in this embodiment, three fixing grooves 520 are provided and arranged along the moving direction of the connecting rod 330, and there is a height difference between two adjacent fixing grooves 520 to correspond to different adjustment angles, thereby realizing multi-level adjustment of the snow discharge angle, thereby meeting the user's personalized adjustment needs.

[0048] Preferably, in this embodiment, the fixing groove 520 is inclined, which not only facilitates the connecting rod 330 to move up and down along the inclined side, but also makes it easy for the connecting rod 330 to be stuck in different fixing grooves 520, effectively ensuring the stability of the foot pedal 310 during use.

[0049] In this embodiment, the movable groove 510 extends along the arrangement direction of the three fixed grooves 520, and is connected to one side of the multiple fixed grooves 520 close to the movable groove 510, so that the connecting rod 330 can move through the movable groove 510 to switch between the multiple fixed grooves 520. When the connecting rod 330 is engaged with different fixed grooves 520, the swing angle of the guide plate 200 is different. Among them, when the connecting rod 330 is engaged in the bottom fixed groove 520, the swing angle of the guide plate 200 is the largest.

[0050] In this embodiment, at least two guide plates 200 are provided, and each guide plate 200 is also provided with a connecting shaft 220 passing through the partition 130, and two adjacent connecting shafts 220 are connected by a linkage 600, so that when any guide plate 200 swings, the guide plate 200 can be driven to swing synchronously, which effectively improves the snow discharge ability of the guide plate 200 and the ability to resist the impact of snow accumulation.

[0051] Preferably, in this embodiment, three guide plates 200 are provided and arranged in a line horizontally, and the linkage member 600 extends along the arrangement direction of the guide plates 200 and is detachably connected to the three connecting shafts 220 respectively, so that the three guide plates 200 can swing synchronously.

[0052] In this embodiment, the partition 130 is further provided with a limiting groove 131 on the side facing away from the guide plate 200, which is slidably connected to the end of the connecting shaft 220 away from the linkage member 600, so as to guide and limit the movement of the connecting shaft 220, thereby effectively improving the swing stability of the guide plate 200.

[0053] The snow sweeping device provided by the embodiment of the utility model has the following angle adjustment method: the user steps on the foot pedal 310 with the foot, so that the foot pedal 310 is pressed down, driving the connecting rod 330 to move downward and get stuck in the corresponding fixed groove 520. When the connecting rod 330 moves, the first rotating shaft 320 rotates, so that the first transmission member 410 rotates toward the foot pedal 310, the third transmission member 430 engages with the first transmission member 410, rotates in the opposite direction, and drives the second transmission member 420 to rotate forwardly. At the same time, the guide plate 200 swings synchronously with the rotation direction of the second transmission member 420, that is, the guide plate 200 swings to the right side, so as to adjust the snow removal angle; when the connecting rod 330 withdraws from the fixed groove 520, the connecting rod 330 moves upward under the action of the elastic member 340, and the foot pedal 310 rises and resets. At this time, the first transmission member 410, the second transmission member 420 and the second transmission member 420 rotate in the opposite direction, so that the guide plate 200 swings to the left side.
