Description
Technical Field
[0001] The utility model relates to the technical field of sanitation equipment, in particular to a rolling and sweeping device and a road sweeper. Background Technique
[0002] A road sweeper, a sanitation equipment for cleaning road garbage, generally includes a vehicle body and a rolling and sweeping device. The vehicle body is used to carry the rolling and sweeping device to move. The rolling and sweeping device includes a housing and a rolling brush. The housing is provided with a feeding port and a cleaning port. The feeding port faces the direction of the vehicle's advance. Garbage enters the cleaning port from the feeding port. The cleaning port faces the ground. The rolling brush rotates in the housing and rolls the garbage in the cleaning port to a storage box.
[0003] When the rolling brush rotates, dust is rolled up by the airflow generated by the rotation of the rolling brush or the rolling brush body in the housing, forming dust. Therefore, if the feeding port is opened too large, some garbage will be ejected from the feeding port. However, the rolling and sweeping device can only clean the garbage attached to the surface to be cleaned, and cannot collect the dust floating in the air. If the feeding port is opened too small, although it can limit the overflow of garbage in the housing, it also intercepts large-volume garbage from entering the housing, resulting in the accumulation of large-volume garbage at the feeding port.
[0004] Therefore, the existing rolling and sweeping device is provided with a flap that can be opened and closed at its feeding port. The flap is hinged to the housing, and the opening diameter of the feeding port is adjusted by flipping the flap. However, it is found in use that when the flap is flipped, it will collide with the garbage in front, causing the garbage to splash.

Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.
[0039] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.
[0040] As Figures 1 to 5 shown, the present utility model provides a rolling and sweeping device, including a housing, a rolling brush 20, and a flap assembly 30. Among them, the housing includes a feed inlet 11 and a cleaning port 12. The cleaning port 12 is opened on the bottom wall of the housing, and the feed inlet 11 is opened at the bottom on one side in the first horizontal direction X; the rolling brush 20 is installed in the housing, and the rolling brush 20 can rotate around its own axis, and the axis is parallel to the second horizontal direction Y. At least part of the bristles 21 of the rolling brush 20 can contact the surface to be cleaned from the cleaning port 12; the flap assembly 30 includes a first driving member 31, a flap 32, and a four-bar linkage mechanism 33. The flap 32 is connected to the housing through the four-bar linkage mechanism 33. The flap 32 has a first position and a second position relative to the housing, and satisfies that, along the projection in the first horizontal direction X, when the flap 32 is in the first position, the shielding area S1 of the feed inlet 11 is greater than S2, where S2 is the shielding area of the feed inlet 11 when the flap 32 is in the second position. The first driving assembly is used to drive the flap 32 to translate between the first position and the second position; the first horizontal direction X and the second horizontal direction Y are arranged at an angle.
[0041] Specifically, the housing includes a front end face 14, a rear end face, a left end face 15 and a right end face 16. Among them, the projections of the front end face 14 and the rear end face in the second horizontal direction Y are both arc-shaped, wrapped outside the rolling brush 20, and fixed by the left end face 15 and the right end face 16, forming a discharge port 13 and a cleaning port in the vertical direction. The feed port 11 is formed at the bottom of the front end face 14. As the rolling and sweeping device moves along the first horizontal direction X, the garbage on the surface to be cleaned can enter the cleaning port from the feed port 11. The rolling brush 20 includes bristles 21 and a roller shaft. The axial ends of the roller shaft are respectively rotatably connected to the left end face 15 and the right end face 16. The bristles 21 are installed on the circumferential side of the roller shaft. The rolling brush 20 can rotate around its own axis to transfer the garbage at the cleaning port to the discharge port 13.
[0042] When the rolling brush 20 rotates, dust is rolled up by the airflow generated by the rotation of the rolling brush 20 or the rolling brush 20 itself in the housing, forming dust flying. Therefore, if the feed port 11 is opened too large, some garbage will be ejected from the feed port 11, and the rolling brush 20 can only clean the garbage attached to the surface to be cleaned, and cannot collect the dust floating in the air. If the feed port 11 is opened too small, although it can limit the overflow of garbage in the housing, it also intercepts large-volume garbage from entering the housing, resulting in the accumulation of large-volume garbage at the feed port 11.
[0043] For this reason, in this embodiment, a flanging assembly is further provided. The flap 32 is connected to the housing through a four-bar linkage mechanism 33. The first driving member 31 is used to drive the flap 32 to move relative to the housing, so that the housing can translate, and the opening size of the feed port 11 can be adjusted in the first horizontal direction X. When there is no large-volume garbage in the front, the flap 32 is in the first position, covering most of the feed port 11 from above, allowing small-volume garbage to enter the housing and restricting the dust in the housing from overflowing. When large-volume garbage appears in the front, the first driving member 31 drives the flap 32 structure to switch to the second position, expanding the opening area of the feed port 11 to allow large-volume garbage to enter the housing. Further, due to the adoption of the four-bar linkage mechanism 33, the flap 32 can translate relative to the housing, reducing the stretching movement of the flap 32 in the first horizontal direction X during the action, and thus avoiding the impact on the garbage in the front when the flap 32 opens and closes the feed port 11, resulting in garbage splashing.
[0044] Optionally, at least two four-bar linkage mechanisms 33 are provided, spaced along the second horizontal direction Y. In this way, by providing at least two four-bar linkage mechanisms 33, the stability between the flap 32 and the housing can be enhanced, and thus the tremor of the flap 32 during the switching between the first position and the second position can be reduced.
[0045] Optionally, the first driving member 31 is an electric push rod or a hydraulic cylinder. In this embodiment, the first driving member 31 is an electric push rod, which includes a first rod body 311 and a second rod body 312 that can slide relative to each other. One end of the first rod body 311 is hinged to the vehicle body, and the other end is sleeved outside the second rod body 312. One end of the second rod body 312 is hinged to the flap 32.
[0046] Optionally, there is one first driving member 31, which is located at the midpoint of the flap 32 in the second horizontal direction Y. The four-bar linkage 33 is symmetrically arranged on the opposite sides of the first driving member 31 in the second horizontal direction Y. In this way, the distances from the first driving member 31 to the four-bar linkages 33 on both sides of the second horizontal direction Y are the same, and the forces are equal, so that the consistency of the movements of both ends of the flap 32 in the second horizontal direction Y is strong.
[0047] In other embodiments, there are at least two first driving members 31, and both the first driving members 31 and the four-bar linkages 33 are symmetrically arranged on the opposite sides of the midpoint of the second horizontal direction Y.
[0048] Optionally, the flap 32 is convexly provided with a third mounting seat 321. The third mounting seat 321 includes two parallel clamping pieces. One end of the first driving member 31 is located between the two clamping pieces and is hinged to the two clamping pieces. In this way, the movement of the first driving member 31 relative to the flap 32 in the second horizontal direction Y can be restricted by the two clamping pieces.
[0049] Optionally, the four-bar linkage 33 includes a first mounting seat 331, a first link 332, a second mounting seat 333, and a second link 334 that are sequentially hinged end to end. The first mounting seat 331 is fixed to the housing, the second mounting seat 333 is fixed to the flap 32, and the first link 332 and the second link 334 are arranged in parallel. Specifically, one end of the first link 332 is connected to the first mounting seat 331 through a first hinge shaft, and the other end is connected to the second mounting seat 333 through a second hinge shaft; one end of the second link 334 is connected to the first mounting seat 331 through a third hinge shaft, and the other end is connected to the second mounting seat 333 through a fourth hinge shaft; among them, the first hinge shaft, the second hinge shaft, the third hinge shaft, and the fourth hinge shaft are all parallel, and the connection line of the first hinge shaft and the third hinge shaft is parallel to the connection of the second hinge shaft and the fourth hinge shaft. In this way, the four-bar linkage 33 encloses a parallelogram, enabling the flap 32 to translate.
[0050] Optionally, the first mounting seat 331 is integrally formed with the housing.
[0051] Optionally, the second mounting seat 333 is integrally formed with the flap 32.
[0052] Optionally, the second mounting seat 333 is L-shaped and includes a first connecting portion 3331 parallel to the first horizontal direction X and a second connecting portion 3332 parallel to the third direction Z. One end of the first connecting portion 3331 is fixed to the flap 32, and the other end is connected to the second connecting portion 3332. Both the first link 332 and the second link 334 are hinged to the second connecting portion 3332; the third direction Z is set at an angle to the horizontal plane.
[0053] Optionally, the third direction Z is the vertical direction perpendicular to the horizontal plane.
[0054] Optionally, the flap 32 includes a mounting frame 322 and a front fender 323. The mounting frame 322 is provided with a U-shaped groove, and a part of the front fender 323 is clamped in the U-shaped groove. The four-link mechanism 33 is connected to the mounting frame 322.
[0055] A road sweeper is also provided, which includes a vehicle body and the above-mentioned rolling and sweeping device, and the housing is installed on the vehicle body.
[0056] Optionally, the road sweeper further includes a storage box, the storage box is fixed to the vehicle body, and the discharge port 13 of the rolling and sweeping device is communicated with the feed port 11 of the storage box.
[0057] In addition, the above is only the preferred embodiment of the present invention and the applied technical principle. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described here. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention.
