The present application provides a snow throwing mechanism for use in a snow removal device.

In one embodiment of the present application, as shown in Figures 3 and 4, the snow throwing mechanism 500 includes the snow throwing mechanism 500 including a mounting member 510 and a plurality of snow throwing blades 520 protruding from one side of the mounting member 510, the mounting member 510 is configured to be connected to a driving mechanism of the snow removal device, and is configured to rotate around its rotation center under the drive of the driving mechanism, the protruding direction of the snow throwing blades 520 is parallel to the rotation axis of the mounting member 510, and the plurality of snow throwing blades 520 are distributed at intervals around the rotation center; the snow throwing blades 520 have a first side 521 and a second side 522 relative to each other, the first side 521 is located on a side of the second side 522 close to the outer periphery of the mounting member 510, and an angle a is formed between the connection between the first side 521 and the mounting member 510 and the line connecting the rotation center and the distribution direction of the first side 521 and the second side 522, and the angle a is 10 degrees to 40 degrees.

It can be understood that, as shown in FIG. 1 and FIG. 2 , the snow throwing mechanism 500 is installed in the snow throwing chamber 220 provided in the housing 200 of the snow removal device, and the housing 200 is also provided with a snow collecting chamber 210 located at the front end of the snow throwing chamber 220, and the snow collecting mechanism 400 is provided in the snow collecting chamber 210, and the snow collecting mechanism 400 is configured to roll in the snow, and then throw the snow in the snow throwing chamber 220 through the snow throwing mechanism 500. In the technical solution of the present application, the first side 521 and the second side 522 are two opposite sides in the extension direction of the snow throwing blade 520, the first side 521 is arranged more outward, and the second side 522 is arranged more inward. Under the action of centrifugal force, the snow entering between the two snow throwing blades 520 from the second side 522 can be thrown out from the first side 521. In the snow throwing mechanism 500 of the present application, there can be an appropriate distance between the first sides 521 of two adjacent snow throwing blades 520 and between the second sides 522 of two adjacent snow throwing blades 520, which can facilitate more snow to pass through and is more conducive to the throwing of snow. In this way, the snow throwing mechanism 500 of the present application can improve the snow throwing efficiency, thereby improving the snow removal efficiency of the snow removal equipment.

Further, in this embodiment, as shown in FIG3 , the snow throwing blade 520 includes a connecting section 523 and a tapered section 524, wherein the connecting section 523 is connected to the mounting member 510, and the tapered section 524 is connected to a side of the connecting section 523 away from the mounting member 510, and the width of the tapered section 524 gradually decreases in a direction away from the connecting section 523. In this way, the tapered section 524 is disposed toward the snow collecting chamber 210, and it is not easy to block the snow in the snow collecting chamber 210 from entering the snow throwing chamber 220, so that the snow in the snow collecting chamber 210 can enter the snow throwing chamber 220 more smoothly and in greater quantities, which is conducive to improving the snow throwing efficiency.

Furthermore, in this embodiment, as shown in FIG3 , a snow crushing part 525 is provided on the side of the tapered section 524 away from the connecting section 523. After the snow throwing mechanism 500 is installed on the snow removal device, the snow crushing part 525 is located on the side of the snow throwing chamber 220 close to the snow collecting chamber 210. When the snow throwing mechanism 500 rotates, on the one hand, the snow crushing part 525 can crush the snow blocks that are not completely crushed by the snow rolling mechanism again, and on the other hand, the snow crushing part 525 can crush the snow blocks that are re-condensed, and the fully crushed snow can be thrown out faster through the snow throwing mechanism 500. In this way, the snow throwing efficiency of the snow throwing mechanism 500 can be further improved by the arrangement of the snow crushing part 525.

Furthermore, in this embodiment, as shown in FIG3 and FIG4 , the snow crushing portion 525 of each snow throwing blade 520 is protruded from the tapered section 524 toward another adjacent snow throwing blade 520, and the multiple snow crushing portions 525 are protruded from the corresponding snow throwing blades 520 in the same direction. In this way, the rotation direction of the snow throwing mechanism 500 is opposite to the protruding direction of the snow crushing portion 525, so that the snow crushing portion 525 can be guaranteed to crush the snow, thereby ensuring the snow throwing efficiency of the snow throwing mechanism 500.

Furthermore, in this embodiment, as shown in FIG. 3 , the extension direction of the first side 521 of the snow throwing blade 520 is parallel to the rotation axis, and the second side 522 of the tapered section 524 gradually approaches the first side 521 in the direction away from the connecting section 523, so that a substantially funnel-shaped space can be formed inside the snow throwing mechanism 500, which is conducive to guiding snow into the snow throwing mechanism 500 and then being thrown out by the snow throwing mechanism 500. The first side 521 of the snow throwing blade 520 and the second side 522 of the connecting section 523 are folded toward the line connecting the first side 521 and the rotation center to form a flange 526, and the protruding direction of the snow crushing portion 525 is opposite to the folding direction of the flange 526. That is, the rotation direction of the snow throwing mechanism 500 will be the same as the folding direction of the flange 526, and the snow in the central area of the mounting member 510 can be thrown out of the snow throwing mechanism 500 through the guidance of the flange 526 of the second side 522 and the flange 526 of the first side 521, thereby improving the snow throwing efficiency of the snow throwing mechanism 500.

Further, in this embodiment, as shown in FIG. 3 and FIG. 4 , the mounting member 510 is connected with a connecting sleeve 530, and the connecting sleeve 530 is configured to be plugged and fixed with the drive shaft of the drive mechanism, and the axis of the connecting sleeve 530 is the rotation axis. In this way, after the drive shaft is fixedly inserted in the connecting sleeve 530, the mounting member 510 can be stably connected to the drive shaft, and can drive the entire snow throwing mechanism 500 to rotate under the drive of the drive shaft, so as to throw the snow entering the snow throwing chamber 220. Among them, the connecting sleeve 530 can be detachably connected to the drive shaft by screwing, so that when one of the output shaft 330 and the snow throwing mechanism 500 is structurally damaged, only the damaged one can be replaced, which is conducive to saving the maintenance cost of the snow removal device. Of course, in other embodiments, the snow throwing mechanism 500 can be fixedly connected to the drive shaft by welding the drive shaft to the mounting member 510.

Furthermore, in this embodiment, as shown in FIG3 and FIG4 , the second side 522 of each of the snow-throwing blades 520 is spaced from the outer periphery of the connecting sleeve 530. In this way, the second side 522 of the snow-throwing blade 520 can have a larger space to facilitate the passage of snow, and the throwing of snow will not be blocked, which is conducive to further improving the snow throwing efficiency of the snow-throwing mechanism 500.

Furthermore, in this embodiment, the number of the snow throwing blades 520 is 4 to 12. The snow throwing mechanism 500 provided with different numbers of snow throwing blades 520 is suitable for different degrees of snow accumulation, so that the operator can select a suitable snow throwing mechanism 500 according to the snow accumulation to be cleared, thereby ensuring the snow throwing efficiency of the snow throwing mechanism 500 and thus ensuring the snow removal efficiency of the snow removal device.

Further, in this embodiment, as shown in FIG. 3 and FIG. 4 , the mounting member 510 is configured as a polygonal structure, the number of the snow-throwing blades 520 is equal to the number of sides of the mounting member 510, and the first side 521 of the snow-throwing blade 520 is correspondingly connected to a corner of the mounting member 510. The mounting member 510 and the snow-throwing blade 520 are configured in this way to form a sufficiently wide channel to facilitate the passage of snow, thereby ensuring the snow-throwing efficiency of the snow-throwing mechanism 500. Without loss of generality, in this embodiment, the mounting member 510 is configured as a regular polygonal structure, such as a square structure as shown in FIG. 3 and FIG. 4 , so that every two adjacent snow-throwing blades 520 can form a uniform channel, which is conducive to further improving the snow-throwing efficiency of the snow-throwing mechanism 500.

The present application also proposes a snow removal device, which includes a snow throwing mechanism 500. The specific structure of the snow throwing mechanism 500 refers to the above embodiment. Since the present snow removal device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The snow removal device also includes a housing 200 and a driving mechanism. The housing 200 is provided with a snow throwing chamber 220, and the snow throwing mechanism 500 is arranged in the snow throwing chamber 220. The driving mechanism drives the mounting member 510 connected to the snow throwing mechanism 500. Furthermore, the housing 200 is also provided with a snow throwing chamber 220, and the snow throwing mechanism 500 is arranged in the snow throwing chamber 220.

Specifically, the driving mechanism includes a driving motor and a reducer 300, the driving mechanism is drivingly connected to the input shaft 320 of the reducer 300, the snow rolling mechanism is fixedly connected to the output shaft 330 of the reducer 300, the driving shaft is the output shaft 330 of the reducer 300, and the snow throwing mechanism 500 is fixedly connected to the input shaft 320 of the reducer 300. Under the drive of the driving motor, the input shaft 320 can drive the snow throwing mechanism 500 and the output shaft 330 to rotate, and the snow collecting mechanism 400 is also driven thereby, so that the snow collecting mechanism 400 and the snow throwing mechanism 500 can be driven to rotate by the driving motor and the reducer 300 at the same time, so as to facilitate the coordinated work of the snow collecting mechanism 400 and the snow throwing mechanism 500. Among them, the speed of the input shaft 320 of the reducer 300 is greater than the speed of the output shaft 330, and the torque of the output shaft 330 is greater than the torque of the input shaft 320, which can meet the power requirements of the snow throwing mechanism 500 and the snow collecting mechanism 400, thereby ensuring the snow removal efficiency of the snow removal device. Furthermore, the diameter of the input shaft 320 is 30 mm to 40 mm, which does not occupy too much space and is not easy to block the snow in the snow collecting chamber 210 from entering the snow throwing chamber 220 .

The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the application concept of the present application, or directly/indirectly used in other related technical fields are included in the patent protection scope of the present application.
