[0041] The following uses specific concrete examples to illustrate the implementation modes of the present utility model. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation modes. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0042] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0043] The main working principle of a snow sweeper is to gather and throw the snow to a designated area through a cutter to achieve the cleaning of snow on roads, courtyards and other places. Snow sweepers can be divided into handheld snow sweepers and ride-on snow sweepers according to the moving mode. However, for any type of snow sweeper, an adjustable snow throwing angle is crucial. The adjustable snow throwing angle enables the operator to adjust the discharge direction of the snow according to needs, avoiding throwing the snow back to the just-cleaned area or causing trouble to other vehicles and pedestrians. In different environments and terrains (such as narrow streets, open parking lots, etc.), adjusting the snow throwing angle can ensure that the snow is effectively discharged to the appropriate position, optimizing the cleaning effect. Under different snowfall amounts and wind speed conditions, adjusting the snow throwing angle can help the snow sweeper better cope with various climate changes, ensuring continuous and efficient snow removal.

[0044] However, the angle adjustment mechanism of existing snow blowers is too complex, often including multiple movable parts and a transmission system. This may lead to increased difficulty in maintenance and repair, requiring regular inspection and maintenance to ensure the normal operation of each component. The complex structure may result in more potential failure points, such as mechanical wear and component failure, increasing the overall failure rate. The angle adjustment mechanism of some snow blowers requires multiple steps to adjust, making the operation rather cumbersome. This may require the operator to have certain experience and skills, especially when operating under harsh weather conditions, which may be even more difficult. During the use of the angle adjustment mechanism, it may shake or displace due to vibration or impact, affecting the snow throwing direction and effect. Especially on relatively rough ground or when operating at high speed, the stability problem is more obvious. The shaking of the adjustment mechanism may lead to a decrease in the accuracy of the snow throwing angle, thus affecting the cleaning effect and increasing the need for secondary cleaning. Therefore, the present utility model improves the snow throwing angle adjustment mechanism of the snow blower. By means of a locking mechanism, the snow guiding plate is maintained at multiple different preset angles, preventing the snow guiding plate from shaking during the operation of the snow blower. The user can unlock the locking mechanism and adjust the angle of the snow guiding plate with one hand, simplifying the device structure and operation process and enhancing the user experience.

[0045] Please refer to Figure 1 - 17 as shown below. The technical solutions of the present utility model will be described in detail with reference to specific embodiments:

[0046] Please refer to Figure 1 - 5 as shown. The snow blower provided by the embodiment of the present utility model includes a housing 10, a snow guiding plate 12, a rotating part 121, and a locking mechanism. It should be understood that the present utility model mainly makes improvements to the angle adjustment mechanism of the snow guiding plate 12. Therefore, the following embodiments will describe in detail the structure and working principle related to the snow guiding plate 12. This does not mean that the snow blower only includes the content described in the present utility model. In fact, the snow blower may also include other components such as a cutter 20, an operating rod 30, a driving module, a control module, etc. Components such as a handle, a control switch, and a battery pack may be provided on the operating rod 30. These components are not the key points protected by the present utility model, so they will not be elaborated herein.

[0047] Please refer to Figure 2 and 3 as shown. The housing 10 forms a snow cleaning cavity. In a specific embodiment, a cutter 20 for gathering and spreading snow may be installed in the snow cleaning cavity, for example.

[0048] Please refer to Figure 2 and 3 as shown. The snow guiding plate 12 is rotatably arranged on the housing 10. Preferably, the housing 10 is provided with a guiding surface 11 for guiding the snow throwing direction. The guiding surface 11 may be one inner wall of the snow cleaning cavity, such as the top wall of the snow cleaning cavity, as Figure 3As shown, during the operation of the snow sweeper, the front end of the top wall of the snow sweeping cavity slopes upward, and the accumulated snow can be thrown forward along the top wall. The snow guiding plate 12 can be rotatably arranged on the guiding surface 11. While the accumulated snow is being thrown along the guiding surface 11, the snow guiding plate 12 can cause the accumulated snow to shift in the width direction of the snow sweeper, so that the accumulated snow is thrown to one side in the width direction of the snow sweeper, ensuring that the accumulated snow after being thrown is far away from the movement path of the snow sweeper and avoiding secondary cleaning.

[0049] Please refer to Figure 2 、 3 As shown, the rotating part 121 is rotatably connected to the machine housing 10 and is in transmission connection with the snow guiding plate 12 for driving the snow guiding plate 12 to rotate. It should be understood that there is no special limitation on the specific form of the rotating part 121. For example, in some embodiments, the rotating part 121 can be a knob, a rotating handle, etc. The rotating part 121 is the power input end for triggering the unlocking and rotation of the snow guiding plate 12, which can be manually operated or the rotating part 121 can be connected to an electric driving element to achieve the automatic unlocking and rotation of the snow guiding plate 12.

[0050] In a specific embodiment, the locking mechanism can be arranged between the rotating part 121 and the machine housing 10 or between the snow guiding plate 12 and the machine housing 10. The locking mechanism is configured to be able to hold the snow guiding plate 12 at multiple preset angles and be able to release the snow guiding plate 12 from multiple preset angles.

[0051] The working principle of the adjusting mechanism of the snow guiding plate 12 will be described below in combination with two different embodiments:

[0052] Embodiment 1

[0053] Please refer to Figure 1 - 9 As shown, in this embodiment, the locking mechanism includes a plug pin 124 and a slot 125. A plurality of slots 125 are arranged on the machine housing 10, and the slots 125 are arranged at intervals around the rotation axis of the rotating part 121. The plug pin 124 is movably connected to the rotating part 121 so that the plug pin 124 can be inserted into or separated from the slot 125, and a driving mechanism for driving the plug pin 124 to move is provided on the rotating part 121. The plurality of slots 125 are evenly distributed on the machine housing 10, enabling the snow guiding plate 12 to switch between multiple preset angles, achieving precise position adjustment to adapt to different snow sweeping requirements. The locking mechanism can effectively hold the snow guiding plate 12 at the preset angle, avoiding accidental loosening due to vibration or other reasons during operation, and enhancing the reliability of the snow sweeper.

[0054] Please refer to Figure 5 - 9As shown, in this embodiment, the driving mechanism includes a driving seat 127, a driving plate 1241 and a driving pin 128, the driving plate 1241 is fixedly connected to the latch 124, the driving pin 128 is fixedly connected to the driving seat 127, and the driving seat 127 is movably connected to the rotating part 121 so that the driving pin 128 and the driving plate 1241 can produce relative displacement, and the relative displacement at least includes displacement in the direction of the rotation axis of the rotating part 121. In a specific embodiment, the driving seat 127 can be hinged to the rotating part 121, for example; the driving plate 1241 is provided with an inclined surface that cooperates with the driving pin 128, and the inclined surface is configured to be able to convert the relative displacement between the driving plate 1241 and the driving pin 128 into a displacement of the latch 124 relative to the rotating part 121. In this embodiment, the user only needs to push and pull the drive seat 127 to achieve the engagement or separation of the pin 124 and the slot 125. Since the drive seat 127 is set on the rotating part 121, the user can drive the pin 124 to separate from the slot 125 and then rotate the rotating part 121 to adjust the angle of the snow guide 12. After the angle of the snow guide 12 is adjusted to the right position, the drive seat 127 is used to drive the pin 124 to engage with the slot 125 to lock the snow guide 12. During the entire operation, the user only needs to operate with one hand and the hand does not need to leave the drive seat 127, which simplifies the operation process and improves the user experience.

[0055] It should be understood that the specific form of the driving mechanism is not unique. For example, in some other embodiments, the driving seat 127 can also be slidably connected to the rotating part 121 along the axial direction of the rotating part 121, and the positions of the driving plate 1241 and the driving pin 128 can be interchanged. For example, the driving plate 1241 is set on the driving seat 127, and the driving pin 128 is set on the pin 124.

[0056] See also Figure 8 , 9 As shown, in an optional embodiment of the present invention, the drive plate 1241 and the drive pin 128 are assembled so that when the two are displaced in the direction of the rotation axis of the rotating part 121, they can drive the latch 124 to move in a direction away from the slot 125; a first elastic element 126 is further provided between the latch 124 and the rotating part 121, and the first elastic element 126 is assembled so that its elastic force can drive the latch 124 to move in a direction close to the slot 125. Figure 9 As shown, in a specific embodiment, there are two inclined surfaces on the drive plate 1241. Whether the drive seat 127 moves upward or downward, it can drive the pin 124 to be pulled out of the slot 125. After the user lets go, the pin 124 can be automatically inserted into the slot 125 under the action of the first elastic element 126, further improving the convenience of operating the locking mechanism.

[0057] See also Figure 6 ,8 As shown, in an alternative embodiment of the present utility model, a plurality of snow guiding plates 12 are provided. A linkage mechanism is provided between the plurality of snow guiding plates 12, and the linkage mechanism is assembled to enable the snow guiding plates 12 to rotate synchronously. The linkage mechanism includes a connecting rod 122 and a plurality of swing arms 123 that are synchronously rotationally connected to the rotating shafts of the respective snow guiding plates 12. The connecting rod 122 is hinged to the swinging ends of the respective swing arms 123. The rotating part 121 is provided with an eccentric shaft 1211, and the eccentric shaft 1211 is hinged to the connecting rod 122 or one of the swing arms 123. In a preferred embodiment, in order to make the rotation angle of the rotating part 121 consistent with the rotation angle of the snow guiding plate 12, the connection line between the center of the rotating part 121 and the center of the eccentric shaft 1211 can be made equal in length and parallel to the effective length of each swing arm 123. The effective length of the swing arm 123 refers to the length of the connection line between the center of the hinge shaft between the swing arm 123 and the connecting rod 122 and the rotation center of the snow guiding plate 12. In a specific embodiment, a spline shaft can be provided on the snow guiding plate 12, and a spline hole can be provided on the swing arm 123. The spline hole cooperates with the spline shaft, so as to realize the synchronous rotation cooperation between the swing arm 123 and the snow guiding plate 12. It should be understood that the connection method between the swing arm 123 and the snow guiding plate 12 is not unique. For example, in some other embodiments, the swing arm 123 can also be connected to the snow guiding plate 12 by screws, or the swing arm 123 and the snow guiding plate 12 can be provided as an integral structure.

[0058] Embodiment 2

[0059] The main difference between this embodiment and Embodiment 1 lies in the structural form of the locking mechanism and the transmission method between the rotating part 121 and the snow guiding plate 12. Specifically:

[0060] Please refer to Figure 10 - 17As shown, in this embodiment, the locking mechanism includes a first locking disc 1291 and a second locking disc 1292. The axes of the first locking disc 1291 and the second locking disc 1292 are collinear with the rotation axis of the rotating part 121 or the turning axis of the snow guide plate 12. The first end face of the first locking disc 1291 is disposed opposite to the second end face of the second locking disc 1292. Protrusions 1294 and depressions 1295 are alternately arranged along the circumferences of the first locking disc 1291 and the second locking disc 1292 on the first end face and the second end face respectively. The first locking disc 1291 and the second locking disc 1292 are arranged to open and close relative to each other along the axial direction. The first locking disc 1291 is fixedly connected to the rotating part 121 or the snow guide plate 12 in the circumferential direction, and the second locking disc 1292 is fixedly connected to the housing 10 in the circumferential direction, wherein the first locking disc 1291 is slidably connected to the rotating part 121 or the snow guide plate 12 along the axial direction. In a specific embodiment, the above circumferential fixed connection and axial sliding connection can be achieved by splines. It should be understood that the installation positions of the first locking disc 1291 and the second locking disc 1292 are not unique. For example, in some other embodiments, the positions of the first locking disc 1291 and the second locking disc 1292 can be interchanged.

[0061] The structures of the protrusions 1294 and depressions 1295 on the first locking disc 1291 and the second locking disc 1292 can provide more accurate angular positioning, ensuring that the snow guide plate 12 can be stably locked between multiple preset angles and reducing position drift caused by vibration or impact. This locking mechanism has a simpler structure. The angle adjustment is achieved through axial sliding, reducing the complexity of mechanical components, which helps to reduce the failure rate and maintenance cost.

[0062] Please refer to Figure 16 As shown, in an alternative embodiment of the present utility model, the sides of the protrusions 1294 and depressions 1295 are ramp-shaped. The locking mechanism further includes a second elastic element 1293, and the second elastic element 1293 is assembled to be capable of driving the first locking disc 1291 and the second locking disc 1292 to close towards each other. In this embodiment, when the driving force received by the rotating part 121 is large enough, the first locking disc 1291 and the second locking disc 1292 can automatically separate under the guidance of the ramp, thereby realizing the automatic unlocking of the locking mechanism, and the operation is simpler.

[0063] Please refer to Figure 12 - 15As shown, the first locking disk 1291 is slidably connected to the rotating part 121 or the rotating shaft of one of the snow guiding plates 12 along its own axial direction, and the second locking disk 1292 is fixedly arranged relative to the machine housing 10; the second elastic element 1293 is assembled such that its elastic force acts on the first locking disk 1291, and the direction of this elastic force faces the second locking disk 1292. Preferably, the first locking disk 1291 is connected to the rotating shaft of one of the snow guiding plates 12 through a spline, and the second locking disk 1292 is sleeved on the rotating shaft of the snow guiding plate 12 loosely. It should be understood that the installation manner of the first locking disk 1291 and the second locking disk 1292 is not unique. For example, in some other embodiments, the first locking disk 1291 can be fixedly arranged relative to the rotating shaft of one of the snow guiding plates 12. At this time, the second locking disk 1292 can be arranged to be a structure that can move axially relative to the machine housing 10, and the elastic force of the second elastic element 1293 acts on the second locking disk 1292. This can also achieve the relative opening and closing movement between the first locking disk 1291 and the second locking disk 1292.

[0064] Please refer to Figure 15 - 17 As shown, in this embodiment, each swing arm 123 is synchronously rotationally connected to the rotating shaft of each snow guiding plate 12 through a first spline. Further, the first splines are unevenly arranged in the circumferential direction of the rotating shaft of the snow guiding plate 12, so that the swing arm 123 and the rotating shaft of the snow guiding plate 12 can only be connected to each other at a preset specific angle, ensuring that the relative positions of each swing arm 123 and each snow guiding plate 12 are consistent, and further ensuring that each snow guiding plate 12 always remains parallel to each other during rotation. In a specific embodiment, for example, the first spline can be set as Figure 17 the structure shown. The first spline removes one body and keyway on the basis of a traditional spline. This anti-misassembly design enables the swing arm 123 and the rotating shaft of the snow guiding plate 12 to be connected to each other only at a specific angle, thereby ensuring the consistency of the angles of each snow guiding plate 12. It should be understood that in some other embodiments, different forms of anti-misassembly designs can also be used to achieve this function. For example, the bodies and keyways can be concentrated on one side of the rotating shaft of the snow guiding plate 12. These anti-misassembly designs can improve the assembly efficiency between the swing arm 123 and the snow guiding plate 12.

[0065] Please refer to Figure 13 As shown, in this embodiment, the rotating part 121 is synchronously rotationally connected to one of the snow guiding plates 12. Specifically, the rotating part 121 can be synchronously rotationally connected to one of the swing arms 123 through a second spline, for example, further simplifying the transmission structure and improving the reliability of the transmission system.

[0066] In summary, the present utility model improves the snow throwing angle adjustment mechanism of the snow sweeper. The snow guiding plate is maintained at multiple different preset angles through the locking mechanism, avoiding the shaking of the snow guiding plate during the operation of the snow sweeper. The user can unlock the locking mechanism and adjust the angle of the snow guiding plate with one hand, simplifying the equipment structure and operation process and enhancing the use experience. Multiple slots are evenly distributed on the machine shell, enabling the snow guiding plate to switch between multiple preset angles and achieving precise position adjustment to adapt to different snow sweeping requirements. The locking mechanism can effectively maintain the snow guiding plate at the preset angle, preventing accidental loosening caused by vibration or other reasons during operation and enhancing the reliability of the snow sweeper. During the entire adjustment process of the snow guiding plate, the user only needs to operate with one hand and does not need to leave the driving seat, further simplifying the operation process and enhancing the use experience.
