Description

Technical Field

[0001] The present invention relates to the technical field of snow blowers, and in particular to a snow blower. Background Art

[0002] As an important device for snow removal, a snow blower can effectively perform snow removal and snow sweeping operations. Snow blowers have been gradually popularized and used at home and abroad. In the current technology, the methods for removing snow mainly include: manual snow removal, chemical solvent snow removal, and mechanical snow removal. Among them, mechanical snow removal is the most effective snow removal method at present. It not only has a fast snow sweeping speed and high snow removal efficiency, but also has a low snow removal cost and does not cause environmental pollution. Therefore, various snow blowers have emerged and have been quickly popularized and applied;

[0003] However, the operation method of the current snow blower is relatively complex. Especially for the snow throwing device of the snow blower, snow throwing, as a core function of the snow blower, can directly affect the working efficiency of the entire snow blower. The orientation of the snow throwing direction is also particularly important during the snow sweeping process. For the operation of the orientation of the snow throwing direction of the existing small snow blowers, most of them change the snow throwing direction by locally rotating a certain part or component, such as changing the snow outlet direction of the snow outlet pipe of the snow blower. This kind of operation needs to pause the work of the snow blower before it can be carried out, which greatly reduces the snow sweeping efficiency and at the same time makes the operation more complex.

Specific Embodiments

[0041] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0042] Embodiment 1: A snow sweeper according to an embodiment of the present invention, as Figures 1 to 8 shown

[0043] The snow sweeper in this embodiment has a snow throwing tube 7 that rotates around a substantially vertical axis. A snow pressing cap 5 is provided on the snow throwing tube 7, and the snow pressing cap can rotate around a substantially horizontal axis. A control device for controlling the snow throwing tube 7 and the snow pressing cap 5 is provided on the snow sweeper, and the control device includes a single operating handle 2 provided on the snow sweeper,

[0044] In this embodiment, the operating handle 2 is connected to the snow throwing tube 7 through a first mechanical linkage device. When the operating handle 2 moves along the first axis direction or the second axis direction on the same plane, the snow throwing tube 7 rotates around a substantially vertical axis. Specifically, the first axis direction is the front-back movement direction of the operating handle 2, and the second axis direction is the left-right movement direction of the operating handle 2. That is, when the operating handle 2 moves forward and backward or left and right, the snow throwing tube 7 is caused to rotate around a substantially vertical axis through the first mechanical linkage device;

[0045] As Figure 1 and Figure 3 shown, the wire reel linkage device includes a rotary traction device 3 and a snow throwing tube wire reel 14 that cooperates with the rotary traction device 3. A wire winder 13 is provided on the rotary traction device 3. By driving the wire winder 13 to rotate through the operating handle 2, the second cable 11 inside the wire winder 13 is pulled to drive the extension section of the second cable 11 inside the snow throwing tube wire reel 14 to rotate the snow throwing tube wire reel 14, thereby controlling the rotation of the snow throwing tube 7 around a substantially vertical axis. The rotating shaft of the snow throwing tube wire reel 14 is fixed to the snow throwing tube 7. That is, when the snow throwing tube wire reel 14 rotates, the snow throwing tube 7 also rotates accordingly.

[0046] The operating handle 2 is connected to the snow pressing cap 5 through a second mechanical linkage device. When the operating handle 2 moves along the third axis direction, the snow pressing cap 5 rotates around a substantially horizontal axis. Specifically, the third axis is perpendicular to the first axis direction and the second axis direction. That is, the third axis direction is the vertical movement direction of the operating handle 2.

[0047] As Figure 6 shown, the second mechanical linkage device is a cable device. Specifically, the cable device includes a first cable 10. The first cable 10 includes a first cable sleeve and a first cable core. One end of the first cable sleeve is provided on the operating handle 2, and the other end is provided on the snow throwing tube 7. A handle bracket 1 is provided on the side of the operating handle 2. One end of the first cable core is provided on the handle bracket 1, and the other end is provided on the snow pressing cap 5. By driving the first cable sleeve to move along the third axis direction through the operating handle 2, that is, the operating handle 2 moves up and down in the vertical direction, the winding and unwinding of the first cable core are controlled, so that the snow pressing cap 5 rotates around a substantially horizontal axis; specifically, the snow pressing cap 5 and the upper part of the snow throwing tube 7 are installed in a hinged manner, and the snow pressing cap 5 can rotate around the rotating shaft at the hinged part. Thus, when the snow pressing cap 5 is pulled up, the throwing angle of the snow thrown by the snow blower through the snow throwing tube 7 and the snow pressing cap 5 becomes larger, and the snow is thrown higher; when the snow pressing cap 5 is pressed down, the snow throwing angle of the snow blower in the direction perpendicular to the horizontal direction becomes smaller, and the snow is thrown lower.

[0048] Embodiment 2: In this embodiment, the snow sweeper has a snow throwing tube 7 that rotates about a substantially vertical axis. A snow pressing cap 5 is provided on the snow throwing tube 7. The snow pressing cap 5 can rotate about a substantially horizontal axis, and a control device for controlling the snow throwing tube 7 and the snow pressing cap 5.

[0049] The control device includes a single operating handle 2 provided on the snow sweeper, a first mechanical linkage device that connects the snow throwing tube 7 to the operating handle 2 and manipulates the operating handle 2 to move along the direction of a first axis or a second axis in the same plane, so that the snow throwing tube 7 rotates about a substantially vertical axis, and a second mechanical linkage device that connects the snow pressing cap 5 to the operating handle 2 and manipulates the operating handle 2 to move up and down, so that the snow pressing cap 5 rotates about a substantially horizontal axis;

[0050] Compared with Embodiment 1, in this embodiment, the rotation direction of the snow pressing cap 5 is basically the same as the movement direction of the operating handle 2. That is, when the operating handle 2 moves upward in the vertical direction of the third axis, the snow pressing cap 5 rotates upward, increasing the throwing angle of the snow and making the snow fly higher; when the operating handle 2 moves downward, the snow pressing cap 5 rotates downward, reducing the throwing angle of the snow and making the snow fly lower. In the actual production process, due to the influence of design errors and assembly errors, as well as the influence of the position relationship of the operating handle 2 itself, the movement direction of the operating handle 2 is not completely vertical and there will be a certain deviation. At the same time, there will also be a certain error in the upward and downward rotation directions of the snow pressing cap 5. With the above design in this embodiment, when the operator controls the movement of the snow pressing cap 5 and moves the operating handle 2 upward by hand, the snow pressing cap 5 also moves upward, and when moving the operating handle 2 downward by hand, the snow pressing cap 5 also moves downward. The consistent movement directions of the two can greatly improve the user experience and are also easier to operate.

[0051] Embodiment 3: Compared with Embodiment 1, in this embodiment, the snow sweeper further has:

[0052] A damping mechanism 20 for holding the snow throwing tube 7 in an adjusted position; a locking mechanism 8 for holding the snow pressing cap 5 in an adjusted position.

[0053] Such as Figure 5As shown, specifically, the damping mechanism 20 includes a limit post 27 provided on the operating handle 2 and a first limit groove disk 28 that cooperates with the limit post 27. The first limit groove disk 28 is located on the outer wall of the rotary traction device 3. A plurality of limit grooves are provided on the first limit groove disk 28. When the operating handle 2 moves along the first axial direction, the snow throwing tube 7 is held in the adjusted position through the cooperation of the limit post 27 and the limit grooves; the limit post 27 is abutted against the first limit groove disk 28 by a second compression spring 26 and is fixed through the limit grooves. By adopting the damping mechanism 20, when the snow throwing tube 7 of the snow sweeper is controlled by the operating handle 2 to rotate around a substantially vertical axis, the rotation adjustment can be made controllable, that is, after the snow throwing angle in the horizontal direction of the snow sweeper is adjusted to a suitable position, it can be fixed to prevent deflection, and the higher the density of the limit grooves between the limit post 27 and the first limit groove disk 28, the higher the control accuracy of the rotation angle of the snow throwing tube 7 rotating around the substantially vertical axis.

[0054] As Figure 6 and Figure 7 shown, specifically, the locking mechanism 8 includes a limiting member 21, a first compression spring 22 and a handle housing 12 provided inside the operating handle 2. One end of the control button 23 abuts against one end of the limiting member 21. A limit hook 25 is provided at the end of the limiting member 21 away from the control button 23, and a second limit groove disk 4 that cooperates with the limit hook 25. A plurality of limit grooves are provided on the second limit groove disk 4. A notch for accommodating the limit hook 25 is provided on the handle housing 12 near the limit hook 25. When the operating handle 2 moves along the third axis direction, the limit hook 25 extends out of the notch of the handle housing 12 and further engages with the limit grooves on the second limit groove disk 4 to hold the snow pressing cap 5 in the adjusted position; further, a plurality of limit grooves of the second limit groove disk 4 are vertically arranged on the handle bracket 1 and are consistent with the movement track of the limit hook 25. Under the elastic force of the first compression spring 22 on the limiting member 21, the limit hook 25 can be engaged and fixed with the second limit groove disk 4. The setting of the locking mechanism 8 can improve the operation safety.

[0055] Embodiment 4: Compared with Embodiment 1, in this embodiment, the snow sweeper further has:

[0056] a locking mechanism 8 for holding the snow pressing cap 5 in the adjusted position, and the locking mechanism 8 is as described in Embodiment 3; an unlocking mechanism for unlocking the locking mechanism.

[0057] In this embodiment, specifically, the unlocking mechanism includes a control button 23 provided on the operating handle and a first compression spring 22 provided inside the operating handle. By pressing the control button 23, the first compression spring 22 is further driven and compressed, so that the locking mechanism 8 is disengaged from the locked position and unlocked; as Figure 7As shown in the figure, a control button 23 is provided at the upper end of the limit member 21. The control button 23 is sleeved on the upper part of the operating handle 2 and abuts against the upper end of the limit member 21. By pressing the control button 23, the limit member 21 rotates around the rotation axis 24 and further compresses the first compression spring 22, so that the limit hook 25 is disengaged from the second limit groove plate 4, and the operating handle 2 can move along the third axis direction;

[0058] When the control button 23 is not pressed, the position of the operating handle 2 in the handle bracket 1 is fixed, that is, it is fixed by the engagement of the limit hook 25 and the second limit groove plate 4. Therefore, only when the control button 23 is pressed, the limit member 21 rotates by a corresponding angle, so that the limit hook 25 is disengaged from the second limit groove plate 4. At this time, the operating handle 2 can move, so as to control the snow pressing cap 5 by moving the operating handle 2 in the third axis direction. The setting of the locking mechanism 8 can also improve the operation safety.

[0059] Embodiment 5: In this embodiment, the snow sweeper has a snow throwing tube 7 that rotates around a substantially vertical axis. A snow pressing cap 5 is provided on the snow throwing tube 7. The snow pressing cap 5 can rotate around a substantially horizontal axis, and a control device for controlling the snow throwing tube 7 and the snow pressing cap 5,

[0060] The control device includes a single operating handle provided on the snow sweeper,

[0061] A first mechanical linkage device that connects the snow throwing tube to the operating handle. When the operator manipulates the operating handle to move in the first axis direction or the second axis direction, the non-motorized force in the first axis direction is transmitted to the snow throwing tube through the first mechanical linkage device, so that the snow throwing tube rotates around the substantially vertical axis.

[0062] A second mechanical linkage device that connects the snow pressing cap 5 to the operating handle. When the operator manipulates the operating handle to move in the third axis direction, the non-motorized force in the second axis direction is transmitted to the snow throwing tube through the second mechanical linkage device, so that the snow pressing cap 5 rotates around the substantially horizontal axis;

[0063] That is, compared with Embodiment 1, the operating handle in this embodiment is manually operated, rather than electrically or other non-manual methods.

[0064] Embodiment 6: In this embodiment, the snow sweeper is a two-step snow sweeper. That is, compared with Embodiments 1 to 5, in this embodiment, the control device for controlling the snow throwing tube 7 and the snow pressing cap 5 of the snow sweeper can also be applied to a two-step snow sweeper.

[0065] Embodiment 7: Compared with Embodiment 1, in this embodiment, the first mechanical linkage device further includes a gear linkage device. The gear linkage device includes an internal gear ring 19 and a gear 15 extending from one side of the winder 13 and meshing with the internal gear ring 19. The rotation of the operating handle 2 drives the rotation of the winder 13 through gear transmission, so as to realize the rotation of the snow throwing tube 7 around a substantially vertical axis through the first mechanical linkage device.

[0066] Embodiment 8: Compared with Embodiment 1, in this embodiment, corresponding sliding rails and sliding grooves are provided on the side walls in contact between the handle bracket 1 and the operating handle 2 to ensure the stable and smooth sliding of the operating handle 2 on the handle bracket 1.

[0067] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
