Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of snow thrower, more particularly, to a snow thrower with anti-blocking structure. BACKGROUND

[0002] The snow thrower is mainly used for removing natural snow on the road, snow accumulated on the roadside and loading operation, and ensuring the traffic safety of the road. The snow thrower has an independent hydraulic system, and the control system adopts electrical control, which is convenient to operate and install, and can be connected and installed with other vehicle chassis such as loaders and tractors for use, and is an ideal device for cleaning snow. The use of the snow thrower not only greatly reduces the workload of sanitation workers and improves work efficiency, but also prolongs the service life of the road and reduces traffic accidents caused by snow accumulation.

[0003] The existing snow thrower has poor adaptability to sticky snow or melted snow. Such snow is easy to stick to the inner wall of the snow throwing cylinder and form stubborn blockage. The traditional snow throwing cylinder adopts a rigid structure. Even if a vibrator is installed, the vibration energy is absorbed due to the rigidity of the structure, and the anti-sticking effect is not good. Secondly, it is difficult to clean and maintain. Once blocked, the operator often needs to climb high or disassemble the bolts for cleaning, which is not only low in efficiency, but also has the risk of high-altitude operation. At the same time, many existing designs use single spiral conveying or direct snow throwing method. The snow removal degree is positively related to the number of spiral heads and the rotation speed, but negatively related to the walking speed of the machine. When the snow is hard or thick, it is easy to cause the load of the machine to increase suddenly or even stop. SUMMARY

Snow-throwing fan blades 223 are rotatably connected inside the snow-throwing pipe 222.

[0019] In a specific embodiment of the present invention, the crushing mechanism 3 pre-crushes the ice and snow, reducing the load on subsequent conveying. The feeding brush 203 and the infeed brush 215 reduce adhesion and adapt to the terrain. The spring telescopic rod 216 ensures that the infeed brush 215 is always in contact with the ground, avoiding snow residue. This comprehensively improves the equipment's adaptability to complex snow conditions such as sticky and compacted snow. The symmetrical spiral design of the conveying auger 225 can actively push the snow towards the center, avoiding snow accumulation on the sides. The snow throwing pipe 222 and the discharge pipe 229 are rotatable and adjustable, reducing the need for manual intervention. The feeding brush 203, the infeed brush 215, and the conveying auger 225 ensure efficient snow collection. The transmission worm 224 and the transmission worm wheel 226 provide strong centrifugal force, increasing the snow throwing distance. This makes the equipment particularly suitable for narrow spaces in units and communities, achieving efficient integrated operation of snow collection, transportation, and throwing.

The surfaces of the second rotating shafts 204 and the surfaces of the first rotating shafts 202 are both fixedly connected with first synchronous pulleys 205, and the two first synchronous pulleys 205 are connected by a first synchronous belt 206.

[0021] In a specific embodiment of the present invention, the first rotating shaft 202 and the second rotating shaft 204 are connected by the first synchronous pulley 205 and the first synchronous belt 206 to realize synchronous power transmission, ensure that the rotation speed of multiple feeding brushes 203 is consistent, avoid snow accumulation or blockage due to speed difference, and simplify the transmission structure and reduce the failure rate.

[0022] Specifically, a third rotating shaft 207 is rotatably connected inside the conveyor box 201.

A second servo motor 228 is fixedly connected to the outer surface of the conveyor box 201, and the output shaft of the second servo motor 228 is fixedly connected to the third rotating shaft 207.

[0023] In a specific embodiment of the present invention, the second servo motor 228 drives the third rotating shaft 207, and the power is redirected to the second rotating shaft 204 through the first bevel gear 208. The first bevel gear 208 has a compact transmission structure, which is suitable for the power conversion from horizontal to vertical, improving space utilization. In addition, the second servo motor 228 has high control precision and can adjust the conveying speed according to the amount of snow.

[0024] Specifically, the conveyor box 201 has two sixth rotating shafts 209 rotatably connected inside. The surface of the third rotating shaft 207 and the surface of one of the sixth rotating shafts 209 are both fixedly connected to a third synchronous pulley 212, and the two third synchronous pulleys 212 are connected by a third synchronous belt 213. The surfaces of the two sixth rotating shafts 209 are both fixedly connected to a second synchronous pulley 210, and the two second synchronous pulleys 210 are connected by a second synchronous belt 211.

[0025] In a specific embodiment of the present invention, the third rotating shaft 207 drives a sixth rotating shaft 209 through the third synchronous pulley 212 and the third synchronous belt 213, and then links another sixth rotating shaft 209 through the second synchronous pulley 210 and the second synchronous belt 211. The multi-stage synchronous transmission is adopted, the power distribution is uniform, and the feeding brush 203 and the feeding brush 215 work together to avoid excessive local load causing jamming.

[0026] Specifically, the conveyor box 201 has two fourth rotating shafts 217 rotatably connected inside. The surface of the other sixth rotating shaft 209 and the surface of the fourth rotating shaft 217 are both fixedly connected with second bevel gears 218, and adjacent second bevel gears 218 mesh. The surface of the fourth rotating shaft 217 and the surface of the feed brush 215 are both fixedly connected with fourth synchronous pulleys 219, and the two fourth synchronous pulleys 219 are connected by a fourth synchronous belt 220.

[0027] In a specific embodiment of the present invention, the sixth rotating shaft 209 transmits power to the fourth rotating shaft 217 through the second bevel gear 218, and then drives the feeding brush 215 through the fourth synchronous pulley 219 and the fourth synchronous belt 220, so as to achieve efficient power steering and distribution, and make the feeding brush 215 on the rotating arm 214 rotate synchronously with the feeding brush 203, thereby improving the snow collection efficiency.

[0028] Specifically, a transmission worm gear 224 is fixedly connected to the surface of the snow-throwing fan blade 223, a transmission worm wheel 226 is fixedly connected to the surface of the fifth rotating shaft 221, and the transmission worm gear 224 meshes with the transmission worm wheel 226. A first servo motor 227 is fixedly connected to the rear side of the snow-throwing tube 222, and the output shaft of the first servo motor 227 is fixedly connected to the snow-throwing fan blade 223. A discharge pipe 229 is rotatably connected to the surface of the snow-throwing tube 222.

[0029] In a specific embodiment of the present invention, the snow-throwing fan blade 223 meshes with the transmission worm gear 224 and the transmission worm wheel 226, converting the rotational motion of the fifth rotating shaft 221 into the high-speed centrifugal motion of the snow-throwing fan blade 223. The discharge pipe 229 can be rotated to adjust the snow-throwing direction to meet different snow-throwing distance and angle requirements.

[0030] Specifically, the crushing mechanism 3 includes a crushing box 301 fixedly connected to the front side of the conveyor box 201. Limiting plates 302 are fixedly connected to both sides of the crushing box 301. Multiple crushing shafts 303 are rotatably connected to the surface of the crushing box 301. Crushing teeth 304 are fixedly connected to the bottom of the crushing shafts 303.

[0031] In a specific embodiment of the present invention, multiple crushing shafts 303 in the crushing box 301 drive crushing teeth 304 to pre-crush the snow. By crushing large pieces of snow or ice, it prevents the snow from directly entering the conveying box 201 and causing blockage, making it more suitable for compacted snow or mixed snow and ice conditions.

[0032] Specifically, multiple crushing shafts 303 are fixedly connected to the surfaces of transmission gears 306, and adjacent transmission gears 306 mesh with each other. A third servo motor 305 is fixedly connected to the surface of the crushing box 301, and the output shaft of the third servo motor 305 is fixedly connected to one of the crushing shafts 303.

[0033] In a specific embodiment of the present invention, adjacent crushing shafts 303 rotate in opposite directions through the meshing of transmission gears 306. The third servo motor 305 provides power, and the transmission gears 306 ensure that the crushing teeth 304 move in an alternating manner, forming a shearing force and improving crushing efficiency. The reverse rotation can also gather snow towards the center and optimize the subsequent conveying process.

[0034] A method for using a snow blower with an anti-clogging structure includes the following steps: First, the crushing teeth 304 of the crushing mechanism 3 break up the snow on the ground, especially compacted ice and snow or large snow blocks. Multiple crushing shafts 303 rotate in an alternating manner to break down the snow blocks into a loose state. The snow then enters the conveying box 201, where it is conveyed backward by the combined action of the feeding brush 203 and the infeed brush 215. The infeed brush 215 on the rotating arm 214 maintains elastic contact with the ground via a spring-loaded telescopic rod 216, adapting to uneven road surfaces and ensuring that no snow is missed during collection. The snow inside the conveying box 201... The dual conveying augers 225 gather snow towards the center and push it toward the inlet of the snow throwing pipe 222. The conveying augers 225 adopt a symmetrical design with left and right rotation, which effectively prevents snow from accumulating on both sides of the box. During the snow throwing stage, the snow throwing fan blades 223 accelerate the snow under the action of centrifugal force and throw it to the designated position through the snow throwing pipe 222 and the discharge pipe 229. The snow throwing fan blades 223 are directly driven by the first servo motor 227 and are linked with the conveying augers 225 through the transmission worm 224 and the transmission worm wheel 226 to ensure that the conveying and snow throwing rhythms are matched.
