Rather, the words “exemplary” or “for example” are intended to present the relevant concept in a specific manner.

[0028] Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 is a snow sweeper 100 provided in the embodiment of the present application.

[0029] In embodiments of the present application, the snow plough 100 can comprise a travelling device 101 and a snow plough device 102. The travelling device 101 can be provided with a travelling mechanism in the form of a tyre or a track, and can be provided with a prime mover. The prime mover can drive the travelling mechanism to work, so that the travelling mechanism can travel on the ground; the prime mover can also provide power and / or energy to the snow plough device 102 and other components of the snow plough 100, so that the snow plough 100 can plough snow during travel. The prime mover can be an internal combustion engine or an electric motor.

[0030] It can be understood that the length direction, the width direction and the height direction of the snow plough 100 can be defined as the first direction, the second direction and the vertical direction respectively. For example, the first direction can be the X direction and the opposite direction thereof as shown in Figure 1 and Figure 2 , and the second direction can be the Y direction and the opposite direction thereof as shown in Figure 1 and Figure 2 , and the vertical direction can be the Z direction and the opposite direction thereof as shown in Figure 1 and Figure 2 .

[0031] The travelling direction of the travelling device 101 when travelling in a straight line can coincide with the first direction.

[0032] In some embodiments, the snow plough 100 can further comprise a lifting device 103. The lifting device 103 can be mounted on the travelling device 101 and can be connected to the snow plough device 102. The lifting device 103 can drive the snow plough device 102 to move in the vertical direction, so that the snow plough device 102 can move away from or approach the ground by rising or falling. As the height of the snow plough device 102 changes, the snow plough device 102 can plough snow at different heights to solve the problem that the snow plough device 102 cannot plough snow when the thickness of the snow is higher than the height of the snow plough device 102.

[0033] The lifting device 103 can comprise a connecting assembly and a lifting drive (not shown). The lifting drive can be housed in the travelling device 101 or fixedly mounted on the travelling device 101. The connecting assembly can be fixedly connected to the lifting drive and rotatably connected to the snow plough device 102. The number of connecting assemblies is two, and they are located on both sides of the snow plough device 102 in the second direction. The lifting drive can drive the connecting assembly to move, so that the snow plough device 102 moves synchronously in the vertical direction.

[0034] In embodiments of the present application, the specific position of the lifting drive is not specifically limited. For example, the travelling device 101 can be provided with a mounting space, and the travelling drive can be located in the mounting space.

[0035] In the embodiments of the present application, the fixing manner when fixedly installed and fixedly connected is not specifically limited. For example, the fixing manner can include, but is not limited to, bolt fixing, welding fixing, interference fit fixing, integral forming fixing, etc.

[0036] It can be understood that the rotatable connection can be achieved by the rotating connecting piece 22, and the connecting manner can make the two components relatively rotate. In the embodiments of the present application, the type of the rotating connecting piece 22 is not specifically limited.

[0037] Please refer to Figure 3 In some embodiments, each connecting assembly can include a plurality of connecting arms 1031. The plurality of connecting arms 1031 can be arranged at intervals in the vertical second direction. One end of each connecting arm 1031 is rotatably connected to the traveling device 101, and the other end is rotatably connected to the snow sweeping device 102. The lifting driving piece can drive at least one connecting arm 1031 to rotate to drive the snow sweeping device 102 to move in the vertical direction.

[0038] In the embodiments of the present application, the number of connecting arms 1031 in each connecting assembly is not specifically limited. For example, in each connecting assembly, the number of connecting arms 1031 can be two.

[0039] In the embodiments of the present application, the type of the lifting driving piece is not specifically limited. For example, the lifting driving piece can be, but is not limited to, a speed reduction motor.

[0040] Please refer to Figure 4 and Figure 5 In some embodiments, the snow sweeping device 102 can include a cover body 10, a snow sweeping assembly, and a guide assembly 20.

[0041] The cover body 10 is rotatably connected with the plurality of connecting arms 1031 to achieve the connection between the snow sweeping device 102 and the traveling device 101. The cover body 10 is provided with an accommodation space 11, and the bottom of the cover body 10 and the side away from the traveling device 101 in the first direction are open. The opening on the cover body 10 is in communication with the accommodation space 11.

[0042] The snow sweeping assembly can include a snow sweeping member 30 and a snow sweeping driving member (not shown in the figure). The snow sweeping member 30 can be located in the accommodating space 11. Part of the structure of the snow sweeping member 30 can extend out of the accommodating space 11 from the bottom to abut against the ground. Part of the structure of the snow sweeping member 30 can extend out of the cover 10 from the side of the cover 10 away from the traveling device 101 in the first direction. The snow sweeping member 30 can be rotatably connected to the cover 10. The snow sweeping member 30 can be in contact with the snow. The snow sweeping driving member can be fixedly connected to the snow sweeping member 30. The snow sweeping driving member can drive the snow sweeping member 30 to rotate. The rotation of the snow sweeping member 30 can cause the snow to enter the accommodating space 11. The snow in the cover 10 can move along the extension direction of the inner wall of the cover 10 under the action of inertia and finally be discharged out of the accommodating space 11 from the top of the cover 10.

[0043] In the embodiment of the present application, the snow sweeping member 30 can be a snow sweeping roller brush. The snow sweeping member 30 can include a connecting roller (not shown in the figure) and a plurality of bristles. The connecting roller can be fixedly connected to the snow sweeping driving member. The snow sweeping driving member can drive the connecting roller to rotate. The axial direction of the connecting roller coincides with the second direction. The plurality of bristles can be fixedly connected to the circumferential portion of the connecting roller. The plurality of bristles can be arranged in a plurality of rows along the circumferential direction of the connecting roller. Each row of bristles can include a plurality of bristles arranged in the second direction. The rotation of the connecting roller can cause the plurality of bristles to rotate. The bristles can be in contact with the snow on the ground and can drive the snow to enter the accommodating space 11 by rotating.

[0044] The number of the guide plates 21 can be a plurality. The plurality of guide plates 21 can be rotatably connected to the top of the cover 10 and located in the accommodating space 11. The plurality of guide plates 21 can be arranged in the second direction. The passages between the plurality of guide plates 21 can be for the snow to pass through. The passages between the guide plates 21 located on the two sides in the second direction and the side walls of the cover 10 can be for the snow to pass through. Each guide plate 21 can guide the snow to be discharged out of the accommodating space 11 in a direction corresponding to the inclination angle of the guide plate 21 by being in contact with the snow in the accommodating space 11.

[0045] It can be understood that the guide plate 21 can adjust the inclination angle by rotating, thereby adjusting the direction of the snow discharged out of the accommodating space 11. By arranging the guide plate 21 on the cover 10 and rotating the guide plate 21 to the angle required by the worker or user, the direction of the snow swept by the snow sweeper 100 can be adjusted. The snow sweeper 100 does not need to adjust the direction of the snow by rotating the body of the snow sweeper 100, which can improve the convenience of the operation of sweeping the snow and throwing the snow.

[0046] In the embodiment of the present application, the installation position of the snow sweeping driving member is not specifically limited. For example, the snow sweeping driving member can be installed on the outside of the cover 10. For another example, the snow sweeping driving member can be installed on the inside of the cover 10 and located in the accommodating space 11.

[0047] In the embodiments of the present application, the type of the snow sweeping driving member is not specifically limited. For example, the snow sweeping driving member can be, but is not limited to, a speed-reducing motor.

[0048] Please refer to Figure 6 In some embodiments, the guide assembly 20 can further include a connecting member 22 and a turning driving member 23.

[0049] The connecting member 22 can extend along the second direction and have a rectangular plate shape. The connecting member 22 can be located in the accommodating space 11. The connecting member 22 can be rotatably connected to a plurality of guide plates 21 at the same angle between each guide plate 21 and the connecting member 22, i.e., each guide plate 21 has the same inclination angle. The turning driving member 23 can be fixedly connected to at least one of the plurality of guide plates 21. The turning driving member 23 has a rotating output shaft connected to the corresponding guide plate 21, so that it can drive the connected guide plate 21 to rotate, thereby causing the remaining guide plates 21 to synchronously rotate under the driving of the connecting member 22.

[0050] It can be understood that, through the connection of the connecting member 22 and the plurality of guide plates 21, the rotation of each guide plate 21 can cause the connecting member 22 to rotate relative to the guide plate 21, thereby causing the other guide plates 21 connected to the connecting member 22 to synchronously rotate, so that the plurality of guide plates 21 can rotate in the same direction by the same angle. In the case that the inclination angles of each guide plate 21 connected to the connecting member 22 are the same, the connecting member 22 can realize linkage between the plurality of guide plates 21, so that each guide plate 21 can synchronously rotate in the same direction by the same angle when the guide plate 21 is rotated under the action of an external force.

[0051] In this way, compared with rotating the plurality of guide plates 21 one by one to adjust the snow throwing direction, the embodiments of the present application can make the plurality of guide plates 21 synchronously rotate through the cooperation of the connecting member 22 and the turning driving member 23, so as to conveniently adjust the snow throwing direction and position of the snow sweeping device 102.

[0052] In the embodiments of the present application, the installation position of the turning driving member 23 is not specifically limited. For example, the turning driving member 23 can be installed outside the cover 10. For another example, the turning driving member 23 can be installed inside the cover 10 and located in the accommodating space 11.

[0053] In the embodiments of the present application, the type of the turning driving member 23 is not specifically limited. For example, the turning driving member 23 can be, but is not limited to, a speed-reducing motor.

[0054] In other embodiments, the number of steering driving members 23 can be multiple, and the number of connecting members 22 can be one or more. The multiple steering driving members 23 can be respectively connected to the guide plates 21 not located on the same connecting member 22, so that the multiple steering driving members 23 can respectively drive the corresponding at least one guide plate 21 to rotate, so that the tilting directions of the multiple guide plates 21 can be different. At this time, the number of guide plates 21 connected on each connecting member 22 is less than the total number of guide plates 21, and there can be some guide plates 21 not connected with the connecting member 22 and connected with a steering driving member 23.

[0055] In this way, the guide plates 21 connected to different connecting members 22 can rotate respectively, so as to adjust the direction of guiding the snow to be thrown by each guide plate 21, so that the snow can be discharged from the snow sweeper 100 to multiple positions where the snow can be stored.

[0056] For example, the multiple guide plates 21 can be divided into two groups, and the two groups of guide plates 21 are respectively directed to the positive direction and the negative direction in the second direction, so that the two groups of guide plates 21 can respectively guide the snow to be discharged from the two sides of the snow sweeper 100 in the second direction. The operator can set storage baskets (not shown in the figure) on the two sides of the snow sweeper 100 in the second direction as needed, and the guide plates 21 can guide the snow to move towards the storage baskets to collect the snow through the storage baskets.

[0057] Please refer to Figure 7 In some embodiments, the connecting member 22 is in sliding fit with the inner side of the cover 10, and the multiple guide plates 21 are all in sliding fit with the inner side of the cover 10. An avoiding groove 211 is formed on each guide plate 21, and the avoiding groove 211 is located on one side of the guide plate 21 in the length direction and on the side of the guide plate 21 close to the inner wall of the cover 10. The connecting member 22 can be partially accommodated in the multiple avoiding grooves 211. When the multiple guide plates 21 rotate, the connecting member 22 can move in the multiple avoiding grooves 211.

[0058] In this way, the guide plates 21 can be in fit with the inner side of the cover 10, and the connecting member 22 can be in fit with the inner wall of the cover 10 at the same time.

[0059] In some embodiments, the cover 10 can include the first baffle 12, the second baffle 13, the two side plates 14, and the two side frames 15.

[0060] The first baffle 12 is an arc-shaped plate. The first baffle 12 is located on one side of the traveling device 101 in the first direction and is spaced apart from the traveling device 101. The bottom end of the first baffle 12 is arranged towards the ground, and the top end can be fixedly connected with the second baffle 13. The second baffle 13 is arranged obliquely to the vertical direction, and the top end of the second baffle 13 is the top end of the cover body 10. The second baffle 13 is a straight plate. Two side plates 14 are respectively located on both sides of the first baffle 12 in the second direction, and both are fixedly connected with the first baffle 12 and connected with the second baffle 13. The passages between the two side plates 14 and the closest guide plates 21 can pass the snow. The first baffle 12, the second baffle 13 and the two side plates 14 can cooperate to form a containing space 11.

[0061] The arc-shaped first baffle 12 can guide the snow to move upwards into the second baffle 13 after the snow enters the containing space 11, and the second baffle 13 can guide the snow to be discharged from the top of the second baffle 13 along the oblique direction of the second baffle 13. The plurality of guide plates 21 are rotatably connected to the second baffle 13, and the plurality of guide plates 21 can be slidingly fitted with the inner side of the second baffle 13, and the connecting piece 22 can be slidingly fitted with the inner side of the second baffle 13. The inner side of the second baffle 13 is the side of the second baffle 13 facing the containing space 11.

[0062] The two side frames 15 can be spaced apart in the second direction, and both are fixedly installed on the outer side of the second baffle 13 and can be fixedly connected with the first baffle 12 at the same time. The two side frames 15 can be connected with two connecting assemblies respectively, and each side frame 15 can be rotatably connected with the corresponding connecting arm 1031 to realize the connection between the cover body 10 and the lifting device 103.

[0063] The bottom of the first baffle 12 is fixedly connected with a scraper 16, the scraper 16 protrudes from the bottom of the cover body 10, and the scraper 16 can abut against the ground. The scraper 16 can scrape the snow or ice layer on the ground when the snow sweeper 100 is running, and the snow sweeping piece 30 can sweep the snow and ice layer scraped up.

[0064] In this way, the situation that the snow layer and the ice layer on the ground are compacted and cannot be swept by the snow sweeping piece 30 can be reduced, and the reliability of the snow sweeping device 102 and the snow sweeper 100 in cleaning snow can be improved.

[0065] In the embodiments of the present application, the material of the scraper 16 is not specifically limited. For example, the material of the scraper 16 can be, but is not limited to, rubber, silicone and the like.

[0066] The snow sweeping device 102 and the snow sweeping vehicle 100 provided by the embodiments of the present application can drive the snow into the containing space 11 by rotating the snow sweeping part 30, and move along the extension direction of the first baffle 12 and the second baffle 13. When the snow moves to the top of the cover body 10, the guide plates 21 can guide the snow to move in the direction corresponding to the inclination angle of the guide plates 21 by contacting the snow, so that the snow can be thrown in the direction corresponding to the inclination direction of the guide plates 21, thereby improving the convenience of adjusting the throwing direction. Meanwhile, the plurality of guide plates 21 can be connected by the connecting piece 22, so that the plurality of guide plates 21 can be linked to rotate, and the rotation of one guide plate 21 driven by the steering driving piece 23 can drive the plurality of guide plates 21 to rotate synchronously, thereby reducing the amount and installation process of the steering driving piece 23, improving the efficiency of assembling the snow sweeping vehicle 100 and saving the cost.

[0067] It is apparent for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the above-described embodiments of the present application are considered to be exemplary and non-limiting in any respect, and the scope of the present application is defined by the appended claims rather than the above description, and thus all changes falling within the meaning and range of the equivalent elements of the claims are intended to be embraced in the present application.
