[0023] Embodiment 1:

[0024] A snow thrower includes a snow collection bin 1 at the bottom. A conveying auger is arranged in the snow collection bin 1. A fan 2 is arranged in the middle or at the end of the snow collection bin 1. In this embodiment, the fan 2 is arranged in the middle of the snow collection bin 1. The conveying auger is arranged in a bidirectional spiral manner, and the spiral directions of the augers on both sides of the fan 2 are opposite and both are driven towards the fan. As Figure 3The described augers with a double - helix arrangement are the left auger 14 and the right auger 15 respectively. Between the left auger 14 and the right auger 15 is a snow - collecting area 16. The blower 2 is arranged at the rear side of the snow - collecting area 16. The air - inlet side of the blower 2 is arranged inside the snow - collecting bin 1. The top of the blower 2 is an air - outlet pipe 21. A conveying pipe 4 is arranged on one side of the air - outlet pipe 21. A driving device is arranged between the air - outlet pipe 21 and the conveying pipe 4. The driving device is a hydraulic motor 3. A driving gear 31 is arranged on the hydraulic motor 3. A driving gear disc 32 is arranged at the bottom of the conveying pipe 4. A driven gear 33 is arranged on the driving gear disc 32. The driven gear 33 meshes with the driving gear disc 32 to drive the relative rotation between the air - outlet pipe 21 and the conveying pipe 4. When this equipment is in operation, there is no need to adjust the driving direction of the vehicle. Only by the engagement drive of the driving gear 31 and the driven gear 33 on the driving gear disc 32 can the snow - throwing point rotate 360 degrees. This kind of structure can quickly adjust the snow - throwing direction. When the position of the accumulated snow is fixed, there is no need to adjust the driving direction of the vehicle, effectively improving the speed of snow cleaning.

[0025] The top of the described conveying pipe 4 is hinged with a snow - throwing section 5. A folding connecting rod is arranged between the conveying pipe 4 and the snow - throwing section 5. As Figure 1 、 2 shown, the folding connecting rod includes a guiding piece 41 fixed on the conveying pipe. A guiding groove 42 is arranged on the guiding piece 41. A snow - throwing section joint 46 is arranged at the bottom of the snow - throwing section 5. The snow - throwing section joint 46 is hinged to the top end of the conveying pipe 4 through a snow - throwing section hinge point 45. A swing connecting rod 43 is also hinged on the snow - throwing section joint 46. The swing connecting rod 43 cooperates with the guiding groove 42 to realize folding guidance. As Figure 6 shown, when this equipment is in a non - snow - cleaning state, it can be stored by folding the snow - throwing section 5, avoiding collision and interference with surrounding objects during driving and occupying a large space during storage.

[0026] The top of the snow - throwing section 5 is hinged with a snow - throwing elbow 6 through a snow - throwing elbow hinge point 62. The snow - throwing elbow 6 changes the vertical snow - throwing into horizontal snow - throwing. A turning driving part is arranged between the snow - throwing section 5 and the snow - throwing elbow 6. This kind of turning driving part is a driving cylinder or a driving screw assembly. In this embodiment, the turning driving part adopts a driving cylinder 7. As Figure 4 、 5 shown, a driving cylinder hinge point 51 is arranged on the back of the snow - throwing section 5. A snow - throwing elbow driving seat 61 is arranged on the snow - throwing elbow 6. A driving cylinder 7 is fixed between the driving cylinder hinge point 51 and the snow - throwing elbow driving seat 61. Through the driving cylinder 7, the angle between the snow - throwing elbow 6 and the snow - throwing section 5 can be adjusted. When conveying snow into the carriage, the height of snow transfer can be adjusted at the top.

[0027] A fixing base 11 is provided at the rear side of the snow collecting bin 1, and is fixed to an external connecting base through the fixing base 11. The external connecting base here can be a traction frame of a towing machine or a middle fixing base of a general automobile. This design is flexible to disassemble and convenient to assemble.

[0028] Furthermore, the blower 2 is arranged at the rear side of the snow collecting bin 1, which can avoid the frontal impact of snow accumulation on the blower.

[0029] Since the bottom of the snow collecting bin 1 rubs against the ground surface all the time when the device is running, it is easy to be damaged after long-term use. To cope with this working condition, a support base 13 is arranged at the bottom of the snow collecting bin 1 of the present utility model, and a shovel plate 17 is bolted to the support base 13. The shovel plate 17 is inclined and arranged towards the front side of the snow collecting bin 1, and can be replaced when the shovel plate 17 is damaged.

[0030] Still further, to improve the overall strength of the snow collecting bin 1, reinforcing ribs 12 are also covered and arranged around the snow collecting bin 1 to achieve overall reinforcement.

[0031] In summary, through structural improvement, the present utility model has been improved in terms of functionality and structural strength, overcoming various problems actually existing in the prior art, and is an ideal snow thrower.
