This snow sweeper has a compact structure, is easy to operate, facilitates manual operation, offers high comfort, high ergonomics, eliminates safety hazards, has low cost, and high economic value. It ensures the stability of the machine's function despite changes in the user's operating environment, making it suitable for families and businesses in snowy areas. However, this snow sweeper cannot automatically steer, resulting in inconvenient steering. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, the present invention provides a snow sweeper, including a frame, a snow sweeping device disposed at the front end of the frame, a drive device disposed inside the frame, wheels disposed on both sides of the frame, a first transmission device connecting the drive device and the wheels, and a manual control component disposed on the frame.

[0005] The first transmission device includes:

[0006] A power shaft is provided, and the drive device is connected to the power shaft. Clutches are mounted at both ends of the power shaft via planetary gear assemblies. Each clutch includes a clutch disc and a first drive wheel. Multiple externally protruding teeth are spaced circumferentially on the outer wall of the clutch disc, with a groove formed between each pair of adjacent teeth. The sun gear of the planetary gear assembly is fixedly mounted to the power shaft. The planetary gear assembly is surrounded by an annular internal gear on the clutch disc. Each planetary gear of the planetary gear assembly meshes with the annular internal gear, and each planetary gear is rotatably connected to one side of the first drive wheel. The first drive wheel on each clutch is connected to the second drive wheels on the two wheels respectively.

[0007] A travel clutch assembly includes a pawl holder, a pawl mounted on the pawl holder, and a pawl release member connecting the pawl holder and the pawl; the pawl is provided with a locking block, which is adapted to fit the groove.

[0008] In one feasible embodiment, the manual control component includes a travel clutch handle, on which a pawl cable is provided for connection to the pawl release member. When the travel clutch handle is lifted, the pawl cable drives the pawl to lift, causing the locking block to disengage from the groove.

[0009] In one feasible embodiment, the drive device includes a walking motor and a reduction gearbox connected to the walking motor, the reduction gearbox being connected to the power shaft.

[0010] In one feasible embodiment, the snow removal device includes an auger motor mounted on a frame, a second transmission device, and a snow removal auger. The auger motor is connected to the snow removal auger via the second transmission device, so that the second transmission device transmits the power of the auger motor to the snow removal auger to make it rotate.

[0011] In one feasible embodiment, the second transmission device includes a first rotating shaft, a second rotating shaft, a first synchronous pulley connected to the auger motor, a second synchronous pulley connected to the second rotating shaft, and a synchronous belt disposed between the first and second synchronous pulleys. The first rotating shaft is mounted on the snow sweeping auger and is provided with a worm gear. The second rotating shaft is provided with a worm, and the worm gear meshes with the worm to connect the first rotating shaft and the second rotating shaft.

[0012] In one feasible embodiment, the planetary gear assembly has three planetary gears, and the first transmission wheel is provided with three connecting posts. Each planetary gear of the planetary gear assembly is rotatably connected to the three connecting posts respectively.

[0013] In one feasible embodiment, the first drive wheel and the second drive wheel on the wheel are connected by a transmission component.

[0014] In one feasible embodiment, the snow removal device further includes a snow removal protective cover, the snow removal auger is disposed inside the protective cover, and the two ends of the first rotating shaft are fixed to the inner walls of the two sides of the protective cover.

[0015] In one feasible embodiment, a through hole is provided on the rear wall of the protective cover for the end of the second rotating shaft without the worm gear to extend out, and the second synchronous pulley is provided at the end of the second rotating shaft that extends out of the protective cover.

[0016] In one feasible embodiment, the protective cover is provided with a snowplow placement slot.

[0017] Compared with the prior art, this application has at least the following beneficial effects:

[0018] In one or more embodiments provided in this application, a drive device is provided inside the snowplow body. The drive device is connected to the wheels via a first transmission device, and the first transmission device includes a clutch and a travel clutch assembly. The two cooperate to control whether the wheels rotate. When the groove of the clutch at one end of the snowplow body engages with the locking block in the travel clutch assembly (i.e., the protrusion is located in the groove), the first transmission wheel on the clutch is driven to rotate, simultaneously driving the second transmission wheel to rotate, and the wheel connected to the second transmission wheel begins to rotate. When the groove of the clutch at the other end of the snowplow body does not engage with the locking block in the travel clutch assembly (i.e., the protrusion is located outside the groove), the first transmission wheel on the clutch stops rotating, the second transmission wheel stops rotating, and the wheel connected to the second transmission wheel also stops rotating. In this case (one wheel continues to rotate, and the other wheel stops rotating), the snowplow turns. In this application, directly controlling whether one wheel rotates to achieve the steering of the snowplow is more convenient. Attached Figure Description

Specific implementation examples:

[0041] Please refer to Figures 1 to 7 As shown, this embodiment provides a snowplow, which includes a frame 100, a snowplow device 200 disposed at the front end of the frame, a drive device 300 disposed inside the frame, wheels 400 disposed on both sides of the frame, a first transmission device 500 connecting the drive device 300 and the wheels 400, and a manual control assembly 600 disposed above the frame; wherein,

[0042] The first transmission device 500 includes:

[0043] A drive shaft 510 is provided, and the drive device 300 is driven to the drive shaft 510. Clutches 520 are mounted on both ends of the drive shaft 510 via planetary gear assemblies. Each clutch 520 includes a clutch disc 5201 and a first drive wheel 521. Multiple externally protruding teeth 522 are spaced circumferentially on the outer wall of the clutch disc 5201, and a groove 523 is formed between each pair of adjacent externally protruding teeth 522. The sun gear 5202 of the planetary gear assembly is fixedly mounted to the drive shaft 510. The planetary gear assembly is surrounded by an annular internal gear on the clutch disc 5201. Each planetary gear 5203 of the planetary gear assembly meshes with the annular internal gear and is rotatably connected to one side of the first drive wheel 521. The first drive wheel 521 on each clutch 520 is driven to the second drive wheels 541 on the two wheels respectively.

[0044] The travel clutch assembly 530 includes a pawl holder 531, a pawl 532 disposed on the pawl holder 531, and a pawl release member 533 connecting the pawl holder 531 and the pawl 532; the pawl 532 is provided with a locking block 5321, which is adapted to the groove 523.

[0045] In this embodiment, a snow sweeping device 200 is provided at the front end of the snow sweeper frame 100, a drive device 300 is provided inside, wheels 400 are provided on both sides, and a manual control component 600 is provided on the top; wherein, a first transmission device 500 is provided between the drive device 200 and the wheels 400, and the drive device 200 controls whether the wheels 400 move through the first transmission device 500. The first transmission device 500 includes a power shaft 510 connected to a drive device 300. To control the steering of the wheel 400, the first transmission device 500 also includes a clutch 520 and a travel clutch assembly 530. The clutch 520 and the travel clutch assembly 530 cooperate to control whether the wheel 400 moves. The clutch 520 has protruding teeth 522, with a groove 523 formed between adjacent protruding teeth 522. The travel clutch assembly 530 has a pawl 532 with a locking block 5321 and a pawl disengagement member 533 that can move the pawl 532. The clutch 520 also has a first transmission wheel 521, which is connected to a second transmission wheel 541 on the wheel. When the locking block 5321 is engaged by the pawl disengagement member 533... When placed in the groove 523, the first transmission wheel 521 on the clutch 520 is driven by the driving force of the drive device 300 and rotates, thereby driving the wheel 400 to rotate and move. When the pawl release member 533 disengages the locking block 5321 from the groove 523, the first transmission wheel 521 is no longer subjected to force and rotates, and the second transmission wheel 541, which is connected to the first transmission wheel 521, also stops rotating, so the wheel 400 stops moving. Thus, when the locking block 5321 at one end is inserted into the groove 523 and the locking block 5321 at the other end is disengaged from the groove 523, the wheel 400 at one end rotates normally while the wheel 400 at the other end stops driving. The snow sweeper turns towards the side of the non-rotating wheel 400. In this embodiment, it is more convenient to directly control the rotation of one of the wheels 400 to achieve the turning of the snow sweeper.

[0046] Preferably, in this embodiment, the planetary gear assembly has three planetary gears 5203, and the first transmission wheel 521 is provided with three connecting posts 5205. Each planetary gear 5203 of the planetary gear assembly is rotatably connected to the three connecting posts 5205 respectively.

[0047] For details, please refer to Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment, the power shaft 510 is provided with a tooth 511, and the clutch 520 includes:

[0048] The clutch disc 5201 is provided with an outer gear ring and an inner gear ring, and the external protruding tooth 522 is the outer gear ring of the clutch disc 5201.

[0049] A planetary gear assembly includes a sun gear 5202 disposed inside a clutch disk 5201 and planetary gears 5203 disposed around the sun gear 5202; the sun gear 5203 is provided with an outer gear ring and an inner gear ring, the outer gear ring of the sun gear 5202 meshes with the planetary gears 5203, and the inner gear ring meshes with the convex teeth 511, thereby fixing the sun gear 5202 to the drive shaft 510; the planetary gears 5203 mesh with the inner gear ring of the clutch disk 5201;

[0050] Planetary carrier 5204, with connecting posts 5205 on one side. The number of connecting posts 5205 is the same as the number of planetary gears 5203, both being three, and their positions correspond to the axis of the planetary gears 5203. The first transmission wheel 521 is located on the other side of the planetary carrier 5204 where the connecting posts 5205 are located.

[0051] In this embodiment, when the latch 5321 on the pawl 532 abuts against the groove 523 on the clutch disc 5201 of the clutch 520, the clutch disc 5201 stops rotating, the drive device 300 drives the power shaft 510 to rotate, the power shaft 510 drives the sun gear 5202 to rotate, and the three planetary gears 5203 meshing with the sun gear 5201 also rotate accordingly. The planet carrier 5204, which is connected to the planetary gears 5203 through the fixed column 5204, also rotates, that is, the first transmission... The drive wheel 521 rotates, and the second drive wheel 541, which is connected to the first drive wheel 521, also rotates, thereby driving the wheel 400 to rotate. When the catch block 5321 on the pawl 532 is in the groove 523 and abuts, the clutch disc 5201 rotates with the planetary gear 5203. The planet carrier 5204 stops rotating because the planetary gear 5203 is rotating in its original position. The first drive wheel 521 also stops rotating, and then the second drive wheel 541 stops rotating, and the wheel 400 stops rotating.

[0052] In this embodiment, the first transmission wheel 521 and the second transmission wheel 541 on the wheel are connected by a transmission component 550. Specifically, as shown... Figure 4 and Figure 5As shown, in this embodiment, both the first transmission wheel 521 and the second transmission wheel 541 are gears with external gear rings, and the transmission component 550 is a chain. However, in other feasible embodiments, the first transmission wheel 521 and the second transmission wheel 541 can be driven by gears, sprockets, or synchronous belts.

[0053] Furthermore, to facilitate user operation, such as Figure 2 As shown, the manual control component 600 of the snow sweeper provided in this embodiment includes a travel clutch handle 610. The travel clutch handle 610 is provided with a pawl pull cable 611 connected to the pawl release component 533. When the travel clutch handle 610 is lifted, the pawl pull cable 611 drives the pawl 532 to lift, so that the locking block 5321 disengages from the groove 523.

[0054] Please refer to Figure 4 As shown, in this embodiment, the drive device 300 includes a walking motor 310 and a reduction gearbox 320 connected to the walking motor 310, and the reduction gearbox 320 is connected to the power shaft 510.

[0055] Preferably, in this embodiment, such as Figure 5 As shown, the snow sweeping device 200 includes an auger motor 210, a second transmission device 220, and a snow sweeping auger 230 mounted on a frame. The auger motor 210 is connected to the snow sweeping auger 230 via the second transmission device 220, so that the second transmission device 220 transmits the power of the auger motor 210 to the snow sweeping auger 230 to make it rotate.

[0056] Furthermore, the second transmission device 220 includes a first rotating shaft 221, a second rotating shaft 222, a first synchronous pulley 223 connected to the auger motor 210, a second synchronous pulley 224 connected to the second rotating shaft 222, and a synchronous belt disposed between the first synchronous pulley 223 and the second synchronous pulley 224. The first rotating shaft 221 is mounted on the snow sweeping auger 230, and a worm gear 2211 is disposed on the first rotating shaft 221. A worm 2221 is disposed on the second rotating shaft 222, and the worm gear 2211 meshes with the worm 2221 to connect the first rotating shaft 221 and the second rotating shaft 222.

[0057] In this embodiment, the snowplow has two separate motors: a walking motor 310 for driving the wheels 400 to move and steer, and an auger motor 210 for driving the snowplow device 200. That is, the snowplow provided in this embodiment uses two motors to independently control the snowplow for snow removal and movement, allowing the user to better control the snowplow and making it easier to use. Furthermore, by setting a synchronous belt and first synchronous pulley 223 and second synchronous pulley 224, the transmission between the auger motor 210 and the first rotating shaft 221 is achieved, reducing transmission noise and ensuring a stable transmission process that is less prone to slippage.

[0058] As a preferred implementation method, such as Figure 5 As shown, the size of the second synchronous pulley 224 is larger than the size of the first synchronous pulley 223, and the reduction ratio between the second synchronous pulley 224 and the first synchronous pulley 223 is in the range of 3 to 6 times.

[0059] Furthermore, the reduction ratio between the worm gear 2211 and the worm wheel 2221 is 1:10.

[0060] Preferably, in other feasible embodiments, a housing may be provided at the worm 2211 and worm wheel 2221 to prevent snow or other foreign objects from entering the transmission connection part of the worm 2211 and worm wheel 2221.

[0061] Preferably, in this embodiment, such as Figure 1 and Figure 3 As shown, the snow sweeping device 200 may be equipped with a protective cover 240, and the snow sweeping auger 230 is disposed inside the protective cover 240. Both ends of the first rotating shaft 221 are fixed to the inner walls of both sides of the protective cover 240. Furthermore, a through hole is provided on the rear wall of the protective cover 240 for the end of the second rotating shaft 222 without the worm gear 2221 to extend out, and a second synchronous pulley 224 is disposed at the end of the second rotating shaft 222 extending out of the protective cover 240. Even further, an impeller may be disposed on the second rotating shaft 222, and the impeller is also disposed inside the protective cover 240.

[0062] Preferred, such as Figure 3 As shown in this embodiment, the protective cover 240 may also be provided with a snowplow placement slot 241 for placing snowplows.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
