Abstract
Description
Technical Field
[0001] This invention relates to the field of engineering equipment technology, specifically to a rotary oscillating device and a snow-shoveling device. Background Technology
[0002] Existing snowplows can only move vertically and can only clear snow on roads where the vehicle's tilt angle matches the road's tilt angle. However, when the vehicle's tilt angle and the road's tilt angle are different, because the bucket can only move vertically (i.e., its tilt angle can only match the vehicle's tilt angle), the bucket cannot keep close to the ground to clear snow, resulting in incomplete snow removal and failing to achieve a good snow removal effect.
[0003] In existing technologies, tiltable buckets rotate using only one axis, which results in unstable mechanisms and unrestricted deflection angles during use. In severe cases, the bucket may hit the ground, causing road damage.
[0004] In summary, there is an urgent need for a rotary oscillating device and snow-shoveling equipment to solve the problems existing in the prior art. Summary of the Invention

[0007] Preferably, the first connecting frame is provided with a first ear plate, the second connecting frame is provided with a second ear plate, and the telescopic mechanism is inclinedly hinged between the first ear plate and the second ear plate to realize the adjustment of the relative height between the two sides of the first connecting frame and the second connecting frame.
[0008] Preferably, the linkage assembly includes a first link and a second link arranged along the height direction of the first connecting frame; the first link is a length-adjustable link.
[0009] Preferably, the first connecting rod is a lead screw connecting rod, including a first screw head, a second screw head, and a threaded sleeve; the first screw head and the second screw head are respectively connected to the two ends of the threaded sleeve; both the first screw head and the second screw head are provided with hinge holes.
[0010] Preferably, the first connecting rod further includes a fastener, the threaded sleeve is provided with a strip hole for inserting the fastener, and the screw head one and / or screw head two are provided with mounting holes for connecting with the fastener.
[0011] Preferably, a rotary oscillating device further includes a scissor mechanism movably connected between the first connecting frame and the second connecting frame.

[0013] Preferably, a rotary yaw device further includes a hinge shaft and a joint bearing;

[0019] The present invention also provides a snow removal device, which is equipped with the above-mentioned rotating and tilting device. The first connecting frame is a vehicle frame for connecting to the vehicle body of the snow removal device; the second connecting frame is a bucket seat for connecting to the snow removal mechanism.
[0020] Preferably, a snow removal device further includes a support shoe disposed at the bottom of the snow removal mechanism. The support shoe is a liftable structure, so that the height of the shovel blade of the snow removal mechanism is 1-2 mm above the ground when the snow is being removed.
[0021] The application of the technical solution of the present invention has the following beneficial effects:
[0022] (1) In this invention, telescopic mechanisms and connecting rod assemblies are symmetrically provided on both sides of the first connecting frame; the telescopic mechanism is connected between the first connecting frame and the second connecting frame to realize the adjustment of the relative position of the first connecting frame and the second connecting frame; when shoveling snow on a level road, the telescopic mechanisms on both sides are consistent in their extension and contraction; when shoveling snow on an uphill or downhill road (the road itself is not inclined), the two telescopic mechanisms are extended or contracted by the same length; when shoveling snow on an inclined road, if the vehicle body inclination is inconsistent with the road inclination, the telescopic mechanism on one side is extended and the telescopic mechanism on the other side is contracted, and the extension and contraction are equal, so that the second connecting frame rotates around the X-axis, so that the inclination angle of the second connecting frame is consistent with the inclination angle of the road. The adjustment process is not affected by the vehicle body inclination, and the inclination angle can be adjusted according to the road conditions. Perfect snow shoveling can be achieved on relatively level roads, roads with one side inclined and the inclination degree is basically consistent, and uphill and downhill roads.
[0023] (2) In this invention, the telescopic mechanism is inclinedly hinged between ear plate one and ear plate two to realize the adjustment of the relative height of the two sides of the first connecting frame and the second connecting frame, thereby realizing the raising, lowering and rotating swing of the second connecting frame (i.e., bucket seat).
[0024] (3) In this invention, the linkage assembly includes a first link and a second link arranged along the height direction of the first connecting frame; the first link is a length adjustable link, which is used to adjust the length of the first link during assembly so that the distance between the two opposite surfaces of the first connecting frame and the second connecting frame is equal everywhere, thereby keeping the first connecting frame and the second connecting frame in a parallel state and improving the stability of the device.
[0025] (4) In this invention, a scissor mechanism is provided between the first connecting frame and the second connecting frame, which can enhance the structural strength and structural stability of the rotary oscillating device.
[0026] (5) In this invention, the adjustment plate is a series of steel plates of different thicknesses. The distance between the inner surface of the diagonal brace and the axis of the diagonal brace screw can be adjusted as needed, and the angle of the second connecting frame swinging around the X-axis can be controlled at 5±0.5° (leftward) or -5±0.5° (rightward), which can achieve perfect snow removal on the inclined road surface such as a small radius turn.
[0027] (6) In this invention, the hinge of three parts can be achieved simultaneously by a single hinge shaft, which can reduce the processing difficulty, reduce the space required for installation, reduce the number of pins during assembly, and also reduce production costs.
[0028] (7) In this invention, each rod is provided with a joint bearing at both ends. The deflection angle of the joint bearing is 7°, so that each rod can swing within a certain range without damaging the rod.
[0029] (8) In this invention, the support shoe is a liftable structure. When the support shoe is set at the bottom of the snow shovel mechanism, the height of the snow shovel plate of the snow shovel mechanism is 1-2 mm higher than the ground when the snow is shoveling, so as to avoid damage to the road surface when the snow shovel plate is shoveling snow.

Detailed Implementation
[0045] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.
[0046] Example:
[0047] See Figures 1 to 12 A rotating sway device and snow removal equipment are disclosed in this embodiment, which are applied to the removal of snow on roads with different inclination states.
[0048] A rotary oscillation device can be applied not only to the snow-clearing equipment in this embodiment, but also to other engineering equipment that requires rotary oscillation. See also Figure 1 The rotary yaw device of this application includes a first connecting frame 1, a second connecting frame 2, a telescopic mechanism 3, and a connecting rod assembly; the first connecting frame 1 and the second connecting frame 2 are arranged in parallel, and the telescopic mechanism 3 and the connecting rod assembly are symmetrically arranged on both sides of the first connecting frame 1; the telescopic mechanism 3 is connected between the first connecting frame 1 and the second connecting frame 2, and is used to adjust the relative position of the first connecting frame 1 and the second connecting frame 2; when shoveling snow on a level road, the telescopic mechanism 3 on both sides extends or retracts by the same length; when shoveling snow on an uphill or downhill road (the road slope is the same as the vehicle body slope), the two telescopic mechanisms 3 extend or retract by the same length, such as... Figure 3 and Figure 4 As shown; when shoveling snow on a sloping road, if the vehicle's tilt angle is inconsistent with the road's tilt angle, the telescopic mechanism 3 on one side extends while the telescopic mechanism 3 on the other side retracts, and the extension and retraction amounts are equal, causing the second connecting frame 2 to rotate... Figure 2 The X-axis rotation in the middle makes the tilt angle of the second connecting frame 2 consistent with the tilt angle of the road surface, and is not affected by the tilt angle of the vehicle body, such as Figure 5As shown, the two ends of the connecting rod assembly are hinged to the first connecting frame 1 and the second connecting frame 2 respectively, to ensure that the first connecting frame 1 and the second connecting frame 2 are always in a parallel state. It also includes a scissor mechanism movably connected between the first connecting frame 1 and the second connecting frame 2, to improve the structural strength and stability of the rotary oscillating device.
[0049] In this embodiment, the telescopic mechanism 3 is a hydraulic cylinder. When the rotary sway device is applied to the snow removal equipment, the first connecting frame 1 is a vehicle frame used to connect with the vehicle body of the snow removal equipment; the second connecting frame 2 is a bucket seat used to connect with the snow removal mechanism 10. The lifting and rotary sway of the snow removal mechanism 10 can be adjusted by the rotary sway device, so that the shovel plate 10.1 of the snow removal mechanism 10 is close to the road surface when shoveling snow, thereby achieving effective snow removal.
[0050] The following section will explain the specific structure of each component.
[0051] See Figure 3 The first connecting frame 1 has four ear plates 1.1 on its lower middle part on both sides, and two hinge seats 1 are formed on the top of the ear plates 1.1. The second connecting frame 2 has four ear plates 2.1, which are used to form two hinge seats 2 on both sides of the top of the second connecting frame 2. The telescopic mechanism 3 is inclinedly hinged between the ear plates 1.1 and the ear plates 2.1 (i.e., hinged between the hinge seats 1 and the hinge seats 2), which is used to adjust the relative height of the two sides of the first connecting frame 1 and the second connecting frame 2, thereby realizing the raising, lowering and rotating swing of the second connecting frame 2.
[0052] The linkage assembly includes a first link 4 and a second link 5 arranged along the height direction of the first connecting frame 1; the first link 4 is a length adjustable link, which is used to adjust the length of the first link 4 during assembly so that the distance between the two opposite surfaces of the first connecting frame 1 and the second connecting frame 2 is equal everywhere, thereby keeping the first connecting frame 1 and the second connecting frame 2 in a parallel state.
[0053] In this embodiment, the top of the first connecting frame 1 is provided with four ear plates 1.2 for forming two hinge seats 3 on the top of the first connecting frame 1, and the top of the second connecting frame 2 is provided with four ear plates 2.2 for forming two hinge seats 4 on the top of the second connecting frame 2. The first connecting rod 4 is hinged between the hinge seats 3 and the hinge seats 4. The bottom of the second connecting frame 2 is provided with four ear plates 2.3 for forming two hinge seats 5. Two hinge seats 6 are formed in the middle of the ear plates 1.1, and the second connecting rod 5 is hinged between the hinge seats 5 and the hinge seats 6.
[0054] In this embodiment, the length adjustment requirement for the first connecting rod 4 is as follows: assuming the distance from the hinge point of hinge seat 3 to the first connecting frame 1 is A, the distance from the hinge point of hinge seat 4 to the second connecting frame 2 is B, the distance from the hinge point of hinge seat 6 to the first connecting frame 1 is C, the distance from the hinge point of hinge seat 5 to the second connecting frame 2 is D, the distance between the two hinge holes of the second connecting rod 5 is E, and the distance between the two hinge holes of the first connecting rod 4 is X, adjusting the length of X so that A+B+X=C+D+E will ensure that the first connecting frame 1 and the second connecting frame 2 remain parallel during the extension and retraction of the telescopic mechanism 3.
[0055] In this embodiment, see Figure 6 and Figure 7 The first connecting rod 4 is a lead screw connecting rod, including a first screw head 4.1, a second screw head 4.2, and a threaded sleeve 4.3; the first screw head 4.1 and the second screw head 4.2 are respectively connected to the two ends of the threaded sleeve 4.3, and the length of the first connecting rod 4 is adjusted by changing the threaded connection position between the first screw head 4.1 and / or the second screw head 4.2 and the threaded sleeve 4.3; both the first screw head 4.1 and the second screw head 4.2 are provided with hinge holes, which are used to connect with the third hinge seat and the fourth hinge seat, respectively.
[0056] The first connecting rod 4 further includes a fastener 4.4. The threaded sleeve 4.3 has a slotted hole for inserting the fastener 4.4, and the screw head 4.1 and / or screw head 4.2 have mounting holes for connecting with the fastener 4.4. In this embodiment, the screw head 4.1 is first connected to the threaded sleeve 4.3 and locked with thread fastener. Then, the screw head 4.2 is connected to the threaded sleeve 4.3. The overall length of the first connecting rod 4 is adjusted by rotating the screw head 4.2. Each time the adjustment is made, the screw head 4.2 is rotated n revolutions (n is a positive integer). After the adjustment is in place, the fastener 4.4 is inserted into the slotted hole of the threaded sleeve 4.3 and the mounting hole of the screw head 4.2 to fix the screw head 4.2 and prevent it from loosening during use. In this embodiment, the fastener 4.4 is a bolt assembly.
[0057] See Figure 8(The panel obstructing the scissor mechanism on the second connecting frame 2 has been removed.) The scissor mechanism includes cross-arranged diagonal bracing rods 6 and diagonal bracing screws 7. A limiting frame 6.1 for inserting the diagonal bracing screw 7 is provided in the middle of the diagonal bracing rod 6. An adjusting plate 6.2 is detachably provided on the inner wall of the limiting frame 6.2. In this embodiment, the adjusting plate 6.2 is a series of steel plates of different thicknesses, which can adjust the distance between the inner surface of the diagonal bracing rod 6 and the axis of the diagonal bracing screw 7 as needed. During the rotation and swaying of the second connecting frame 2, the diagonal brace 6 and the diagonal brace screw 7 also deflect accordingly. During the deflection, the diagonal brace screw 7 contacts the adjustment plate 6.2 inside the limiting frame 6.1. The adjustment plate 6.2 limits the deflection angle of the diagonal brace screw 7 and controls the angle of the second connecting frame 2's sway around the X-axis to 5±0.5° (leftward deflection) or -5±0.5° (rightward deflection). This allows for perfect snow removal on sloping roads, such as those with small radius turns. The diagonal brace screw 7 is a length-adjustable rod, and its structure and length adjustment principle are similar to those of the first connecting rod 4, which will not be described in detail here.
[0058] A rotary yaw mechanism further includes a hinge shaft 8 and a spherical bearing 9; see also Figure 9 The hinge axis 8 can be configured in the following ways:
[0059] The hinge shaft 8 is hinged to the ear plate 1.1 of the first connecting frame 1, the second connecting rod 5 and the diagonal brace 6 respectively;
[0060] Alternatively, the hinge shaft 8 is hinged to the ear plate 1.1 of the first connecting frame 1, the second connecting rod 5 and the diagonal bracing rod 7 respectively;
[0061] Alternatively, the hinge shaft 8 is hinged to the ear plate 2.3, the second connecting rod 5, and the diagonal brace 6 of the second connecting frame 2, respectively;
[0062] Alternatively, the hinge shaft 8 is hinged to the ear plate 2.3, the second connecting rod 5, and the diagonal bracing rod 7 of the second connecting frame 2, respectively;
[0063] By using a single hinge shaft 8 to hinge the three components, the processing difficulty can be reduced, the space required for installation can be decreased, the number of pins required for assembly can be reduced, and the production cost can also be reduced. Furthermore, the pins at both ends of the telescopic mechanism 3 and the first connecting rod 4 can be the pins used in existing technologies.
[0064] The joint bearing 9 is provided at each hinge point. Specifically, each rod has a joint bearing 9 at both ends. The maximum allowable deflection angle of the joint bearing 9 is 7°, so that each rod can swing within a certain range without damaging the rod.
[0065] A snow removal device is provided with the above-mentioned rotating and swaying device, and further includes a support shoe 11 disposed at the bottom of the snow removal mechanism 10. The support shoe 11 is a liftable structure, so that the height of the shovel plate 10.1 of the snow removal mechanism 10 is 1-2 mm higher than the ground when the snow is being removed.
[0066] In this embodiment, the support boot 11 is raised and lowered by a hydraulic cylinder. When shoveling snow, the bottom of the support boot 11 is lower than the shovel plate 10.1, so that the height of the shovel plate 10.1 is 1-2mm higher than the ground, thus avoiding damage to the road surface when the shovel plate 10.1 is shoveling snow.
[0067] The above-mentioned method of using the rotary oscillation device and snow removal equipment is as follows:
[0068] Step 1: Adjust the length of the first connecting rod 4 so that the assembled first connecting frame 1 and the second connecting frame 2 are parallel; select an adjustment plate 6.2 of appropriate thickness and install the adjustment plate 6.2 inside the limit frame 6.1 so that the deflection angle is controlled at 5±0.5° (deflection to the left) or -5±0.5° (deflection to the right);
[0069] Step 2: Connect the first connecting frame 1 of the rotary sway device to the vehicle body of the snow removal equipment, and install the snow removal mechanism 10 on the second connecting frame 2;
[0070] Step 3: Control the telescopic mechanisms 3 on both sides of the first connecting frame 1 and the support shoe 11 at the bottom of the snow shovel mechanism 10 according to the road conditions, so that the shovel plate 10.1 is close to the ground and the bottom edge of the shovel plate 10.1 is 1-2mm away from the ground. By rotating the swaying device, the shovel plate 10.1 is aligned with the ground plane, and the snow shovel work can begin.
[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
