[0039] The embodiment is described with reference to the accompanying drawings, and a kind of snow removing device is provided, comprising:

[0040] The front-end collecting assembly 1 is arranged on the bearing assembly 5, and a spiral roller 1-2 is arranged in the front-end collecting assembly 1; the spiral roller 1-2 is provided with two sections of spiral blades with opposite rotation directions, and a plurality of push plates 1-2-4 are arranged between the adjacent positions of the two sections of spiral blades in the axial direction of the spiral roller 1-2.

[0041] The lifting assembly 2 is connected with the front-end collecting assembly 1, and the inlet of the lifting assembly 2 corresponds in space to the push plates 1-2-4.

[0042] The output assembly 3 is connected with the bearing assembly 5, and the outlet of the lifting assembly 2 corresponds in space to the input of the output assembly 3.

[0043] The front-end collecting assembly 1 is arranged at the front end of the bearing assembly 5 in the advancing direction, the spiral roller 1-2 is driven by a hydraulic motor, the two sections of spiral blades with opposite rotation directions move the snow towards the inlet of the lifting assembly 2, which causes the snow to accumulate at the inlet; if the lifting assembly 2 is simply relied on to discharge the accumulated snow in the front-end collecting assembly 1, the efficiency is low, and the mechanical load is increased; however, under the action of the push plates 1-2-4, the snow can be discharged towards the inlet of the lifting assembly 2, and the snow can be more effectively pushed into the inlet of the lifting assembly 2.

[0044] The lifting assembly 2 conveys the snow into the output assembly 3, the output assembly 3 can rotate, the discharge position of the output assembly 3 can be adjusted, and the output assembly 3 can be rotated to the left side or the right side of the bearing assembly 5 in the advancing direction, so as to discharge the snow into a snow plow or a roadside, or the output assembly 3 can be kept in the tail direction to discharge the snow backward.

[0045] In the embodiment, the spiral roller 1-2 further includes a main shaft 1-2-1, a support rod 1-2-2, a positive spiral blade 1-2-3 and a reverse spiral blade 1-2-5, the support rod 1-2-2 is arranged on the main shaft 1-2-1, the positive spiral blade 1-2-3 and the reverse spiral blade 1-2-5 are fixedly connected to the support rod 1-2-2, and the push plate 1-2-4 is fixedly arranged at the adjacent positions of the positive spiral blade 1-2-3 and the reverse spiral blade 1-2-5 in the axial direction of the main shaft 1-2-1.

[0046] The rotation of the main shaft 1-2-1 drives the rotation of the support rod 1-2-2, the rotation of the support rod 1-2-2 drives the rotation of the positive spiral blade 1-2-3 and the reverse spiral blade 1-2-5, the rotation of the positive spiral blade 1-2-3 and the reverse spiral blade 1-2-5 converges the snow therebetween, and then the snow is discharged through the lifting assembly 2; however, the snow lacks a pushing force towards the inlet of the lifting assembly 2 after reaching the converging position, which causes poor discharge effect and even overloading of the spiral roller 1-2 and the power assembly; however, the push plate 1-2-4 arranged between the positive spiral blade 1-2-3 and the reverse spiral blade 1-2-5 can effectively push the snow towards the inlet of the lifting assembly 2 and accelerate the discharge speed.

[0047] The pushing plate 1-2-4 is arranged along the axial direction of the main shaft 1-2-1 and is uniformly distributed along the radial direction of the main shaft 1-2-1, preferably three.

[0048] In the embodiment, the front-end collecting assembly 1 further comprises a collecting shell 1-1 and a splash-proof roller 1-3, the spiral roller 1-2 and the splash-proof roller 1-3 are arranged axially in parallel inside the collecting shell 1-1, the splash-proof roller 1-3 rotates synchronously with the spiral roller 1-2, and the splash-proof roller 1-3 is provided with spiral fins.

[0049] The splash-proof roller 1-3 and the spiral roller 1-2 are connected with the power output assembly hydraulic motor through a chain, the hydraulic motor rotates to drive the splash-proof roller 1-3 and the spiral roller 1-2 to rotate, on the one hand, when the spiral roller 1-2 rotates, the snow will be thrown onto the collecting shell 1-1, part of the snow will be attached to the collecting shell 1-1, and the amount of the snow will increase, finally resulting in that the snow contacts the spiral roller 1-2, affecting the rotation of the spiral roller 1-2, on the other hand, if the collecting shell 1-1 is arranged to be relatively small, the snow cannot be attached to the collecting shell 1-1, but the snow will be thrown out through the gap between the upper part of the spiral roller 1-2 and the collecting shell 1-1 when the spiral roller 1-2 rotates, affecting the collecting effect, therefore, the originally thrown snow on the collecting shell 1-1 can be thrown onto the splash-proof roller 1-3 by adding the rotating splash-proof roller 1-3, and the snow is discharged back to the spiral roller 1-2 through the rotation of the splash-proof roller 1-3.

[0053] In the embodiment, the lifting part 2-2 is provided with annular belts on both sides, and a horizontal plate is arranged between the two annular belts. The horizontal plate pushes the snow upwards, which can reduce the snow adhering to the belts and make the snow passing through the outlet but not discharged directly slide into the lower shell 2-1 through the space between the two annular belts and move towards the outlet. The hydraulic motor driving the lifting assembly 2 drives the rollers to rotate, the rollers drive the annular belts to rotate, the annular belts drive the horizontal plate to move, and the moving direction of the horizontal plate close to the lower shell 2-1 is from the front-end collecting assembly 1 to the output assembly 3, so that the snow moves upwards, while the horizontal plate away from the lower shell 2-1 moves in the opposite direction and returns to the inlet to carry the snow.

[0054] In the embodiment, the lifting assembly 2 further comprises a splash guard 2-3 arranged on the upper part of the outlet of the lower shell 2-1.

[0055] The snow moves upwards along the lifting part 2-2, and most of the snow is discharged onto the output assembly 3 after reaching the outlet, but a part of the snow adheres to the horizontal plate.

The hydraulic pump controlling the hydraulic rod 3-7 can control the length of the hydraulic rod 3-7 by supplying and recovering hydraulic oil, so as to adjust the angle of the outer frame 3-1 relative to the base 3-6. At the same time, the rotation of the gear set 3-5 drives the inner frame to move relative to the outer frame 3-1, so as to make the discharge distance far or close. Rollers are arranged on the outer frame 3-1 and the inner frame 3-2 for carrying the conveying belt 3-3. One of the rollers is driven by the hydraulic motor, and the rotation of the roller drives the conveying belt to rotate.
