DETAILED DESCRIPTION

[0030] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0031] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0032] See also Figure 1 , 2 As shown, the snowplow 100 provided by the utility model can be mounted on the mobile vehicle 300 , specifically, for example, it can be mounted on the front end or both sides of the mobile vehicle 300 . In order to more conveniently connect the snowplow 100 and the mobile vehicle 300, the snowplow 100 can be installed on an external vehicle 200, and then the external vehicle 200 is connected to the mobile vehicle 300. The external vehicle 200 can be a non-powered vehicle. In a specific embodiment, the external vehicle 200 can also be provided with an adjustment mechanism for adjusting the posture or height of the snowplow 100, such as hingedly connecting the snowplow 100 to the external vehicle 200, and providing a telescopic drive element between the snowplow 100 and the external vehicle 200 to facilitate driving the snowplow 100 close to or away from the ground; when snow removal operations are required, the snowplow 100 can be driven close to the ground to ensure thorough snow removal, and when the snow removal work is completed or in the process of transferring the snowplow 100, the snowplow 100 can be driven away from the ground to improve the vehicle's passability. Of course, in some other embodiments, the external vehicle 200 may be omitted, and the snowplow 100 may be directly installed on the mobile vehicle 300 .

[0033] The driving components and working components of existing snowplows are generally driven by a pulley mechanism, but the pulley mechanism is large in size, which affects the flexibility of the snowplow, and the pulley mechanism has low transmission efficiency, which will cause unnecessary energy waste, especially in icy and snowy weather environments, which will seriously affect the endurance of the snowplow. To this end, the utility model provides a snowplow 100 driven by gears, which integrates the motor 31 and the planetary reducer 32 together, which can significantly reduce the volume of the driving components and the transmission components and improve the flexibility of the snowplow 100; in addition, the transmission path between the driving components and the working components is shorter, the transmission efficiency is higher, and the endurance of the snowplow 100 can be effectively improved.

[0034] See also Figure 3-10 As shown, the technical solution of the present invention is described in detail below in conjunction with specific embodiments:

[0035] See also Figure 2 , 3As shown in FIGS. 6-8 and 10 , the snow sweeper 100 provided in the embodiment of the utility model includes a housing 10 , a tool assembly 20 , and a drive assembly 30 .

[0036] See also Figure 2 , 3 As shown, the shell 10 is provided with an opening; when the snowplow 100 moves forward, the snow on the ground can enter the shell 10 from the front side of the shell 10; in a specific embodiment, the shell 10 can be, for example, composed of multiple plates joined by welding, riveting, bolting, etc. Of course, in some other embodiments, the shell 10 can also be integrally formed by stamping, die-casting, etc.

[0037] See also Figure 2 , 4 As shown in Figure 5, the tool assembly 20 is installed in the shell 10; in a specific embodiment, the tool assembly 20 may include, for example, a snow thrower 21 and a snow rolling knife 22, wherein the snow rolling knife 22 is used to gather the snow in the width direction of the snowplow 100 at one place, and the snow thrower 21 is used to throw the gathered snow to the outside of the road.

[0038] See also Figure 4 , 5 As shown, in a specific embodiment, the snow roller 22 may include, for example, a first blade, which can push the accumulated snow to move along the width direction of the snowplow 100 during rotation, thereby gathering the accumulated snow at one place; for example, the first blade may be two sections of spiral blades with opposite rotation directions that are symmetrically arranged about the center of the width direction of the snowplow 100, and in this case, the first blade can gather the accumulated snow in the width direction of the snowplow 100 to the center of the width direction of the snowplow 100; it should be understood that the arrangement of the snow roller 22 is not unique, for example, in some other embodiments, the snow roller 22 may also be a section of spiral blades with a single rotation direction, and in this case, the first blade can push the accumulated snow in the width direction of the snowplow 100 to one end of the width direction of the snowplow 100.

[0039] See also Figure 5As shown, in a specific embodiment, the snow thrower 21 may include, for example, a base, and at least two second blades spaced apart along the circumferential direction of the base; the position of the snow thrower 21 in the width direction of the snowplow 100 is determined by the working mode of the snow roller 22. For example, when the snow roller 22 gathers the snow accumulated in the width direction of the snowplow 100 to the middle of the width direction of the snowplow 100, the snow thrower 21 should be installed in the middle of the width direction of the snowplow 100, and when the snow roller 22 gathers the snow accumulated in the width direction of the snowplow 100 to one side of the width direction of the snowplow 100, the snow thrower 21 should be set on the side where the snow is gathered. The working principle of the snow throwing knife 21 is to use centrifugal force to throw away the accumulated snow. Therefore, a corresponding guiding structure needs to be provided on the shell 10 to guide the snow throwing path. For example, a snow discharge cylinder assembly for guiding the snow throwing path can be provided on the shell 10. In a further embodiment, the snow discharge cylinder assembly can be movably connected to the shell 10 to make the snow throwing direction adjustable.

[0040] See also Figure 3 , 6 -10, the drive assembly 30 is installed outside the housing 10, and the drive assembly 30 includes a motor 31 and a planetary reducer 32. The power input end of the planetary reducer 32 is connected to the output shaft 311 of the motor 31, and the power output end of the planetary reducer 32 is connected to the tool assembly 20 through a transmission structure; the motor 31 and the planetary reducer 32 are integrated in the same housing 33. Compared with the pulley transmission mechanism, the structure of the planetary reducer 32 is more compact. On this basis, the utility model integrates the planetary reducer 32 with the motor 31, further reducing the axial size of the drive assembly 30 and improving the flexibility of the snowplow 100; at the same time, the utility model also reduces the number of parts and simplifies the assembly process.

[0041] See also Figure 6 , 10 As shown, in an optional embodiment of the utility model, the planetary reducer 32 includes a sun gear 321, a planet carrier 322, a planetary gear 323 and a ring gear 324, the sun gear 321 and the output shaft 311 of the motor 31 are relatively fixedly arranged, the planet carrier 322 is rotatably connected to the housing 33, the ring gear 324 is fixedly connected to the housing 33, the planetary gear 323 is rotatably connected to the planet carrier 322, and the planetary gear 323 is respectively meshed with the sun gear 321 and the ring gear 324, and the planet carrier 322 constitutes the power output end of the planetary reducer 32.

[0042] The transmission principle of the drive assembly 30 is as follows: the output shaft 311 of the motor 31 drives the sun gear 321 to rotate. Since the planetary gear 323 is meshed with the sun gear 321, the planetary gear 323 and the sun gear 321 rotate synchronously in the opposite direction. Since the planetary gear 323 is meshed with the ring gear 324, the planetary gear 323 rolls along the circumferential direction of the ring gear 324, thereby driving the planet carrier 322 to rotate. It should be understood that the reduction ratio of the planetary reducer 32 is determined by the transmission ratio between the sun gear 321 and the planetary gear 323 and the transmission ratio between the planetary gear 323 and the ring gear 324. In practical applications, the planetary reducer 32 can achieve the desired reduction effect by controlling the transmission ratio between the sun gear 321 and the planetary gear 323 or the transmission ratio between the planetary gear 323 and the ring gear 324.

In order to ensure the dynamic balance of the planet carrier 322, a plurality of planetary gears 323 may be arranged at equal intervals along the circumferential direction of the planet carrier 322. In this embodiment, the planetary gear 323 is installed inside the planet carrier 322, and rotation supports may be provided at both ends of the planet carrier 322, which can effectively improve the stability of the planet carrier 322 during operation.

[0044] It should be understood that the assembly method between the planet carrier 322 and the planet gear 323 is not unique. For example, in some other embodiments, the planet gear 323 can also be directly installed on one end of the planet carrier 322.
