Description

Technical Field

[0001] The utility model relates to the technical field of sweepers, in particular to an automatic opening and closing mechanism for a front baffle of a garbage bin of a sweeper. Background Art

[0002] The sweeper is an integrated garbage sweeper that combines sweeping and vacuuming. It has the advantages of high work efficiency, low cleaning cost, good cleaning effect, high safety performance, high economic return rate, etc. It has been widely used in cleaning roads in large, medium and small cities. The roller brush sweeper is equipped with a roller sweeping brush at the bottom of the vehicle. When the vehicle moves forward, the aforementioned roller sweeping brush will directly roll the garbage and sand on the ground into the waste collection box on the vehicle. When encountering larger garbage, it is necessary to lift the front baffle of the roller brush to facilitate the garbage to enter the garbage bin; when the existing front baffle is rising, since the front baffle will tilt away from the top of the roller brush when it rises again, the bottom of the front baffle will push the garbage to the side away from the cleaning roller brush. When the front baffle is fully lifted, it will directly contact the cleaning roller brush, and the rotation of the cleaning roller brush will easily bounce the garbage away. Utility Model Content

[0007] Preferably, the top of the electric push rod is rotatably connected to a third rotating shaft, the third rotating shaft is rotatably connected to a rotating seat, and the top of the rotating seat is connected to the bottom of the chassis of the sweeper body.

[0008] Preferably, the cab of the sweeper body is provided with a steering wheel, and the steering wheel is provided with paddles for controlling the electric push rod.

[0009] The above one or more technical solutions in the automatic opening and closing mechanism of the front baffle of the sweeper garbage bin provided by the embodiment of the utility model have at least one of the following technical effects:

[0010] Under normal use, the front baffle covers the front of the cleaning roller brush to prevent dust in the roller brush cover from flying outward; when the sweeper encounters large amounts of garbage, the electric push rod pulls the lifting point, which drives the connecting rod and the front baffle to swing in a fan shape with the rotating fulcrum as the rotation center, and the connecting rod swings upward, while driving the front baffle to swing in an arc upward and away from the cleaning roller brush. During this process, the garbage is first pushed forward by the front baffle and continues to move forward. As the front baffle swings upward in an arc, the garbage gradually moves toward the direction of the cleaning roller brush. When the front baffle is completely swung upward, the garbage is swept into the garbage bin by the cleaning roller brush to achieve a cleaning effect. Compared with the front baffle in the prior art, the front baffle of this technical solution will gradually move toward the direction of the cleaning roller brush when the garbage contacts the cleaning roller brush, has a certain buffering effect, a simple structure, fewer steps in operation, and higher operating efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0020] In one embodiment of the present invention, Figures 1 to 3As shown, an automatic opening and closing mechanism for the front baffle of a sweeper garbage bin is provided, comprising a sweeper body 1, a roller brush cover 2 is provided at the bottom of the chassis of the sweeper body 1, a cleaning roller brush 3 is rollingly connected inside the roller brush cover 2, a baffle assembly 4 and a rotating fulcrum 21 are provided on the side of the roller brush cover 2 close to the front of the vehicle, the rotating fulcrum 21 is installed on the side wall of the roller brush cover 2 close to the front of the vehicle, the baffle assembly 4 comprises a front baffle 41 and an electric push rod 42, a connecting rod 411 extends from the side of the front baffle 41 in the direction close to the front of the vehicle, the other end of the connecting rod 411 is rotatably connected to the rotating fulcrum 21, a lifting point 43 is provided in the middle of the connecting rod 411, and the output shaft of the electric push rod 42 is connected to the lifting point 43.

[0021] Furthermore, the lifting point 43 includes a base 431 and a first rotating shaft 432. The base 431 is provided with a through hole, the axial direction of the through hole is perpendicular to the side wall of the roller brush cover 2, the first rotating shaft 432 is installed in the through hole, and one side of the first rotating shaft 432 is connected to the output shaft of the electric push rod 42. Specifically, the electric push rod 42 pulls the first rotating shaft 432, and the base 431 and the connecting rod 411 are driven by the first rotating shaft 432 to realize the arc swing of the front baffle 41. In this process, the connecting rod 411 is also tilted at the same time. By setting the first rotating shaft 432, a smoother operation can be achieved.

[0022] Furthermore, a fixing point 5 and a spring 22 with one end connected to the fixing point 5 are provided on the side wall of the roller brush cover 2 , and the other end of the spring 22 is connected to the first rotating shaft 432 .

[0023] Furthermore, the fixed point 5 is provided with a second rotating shaft 51, and the second rotating shaft 51 is connected to the spring 22. Specifically, when the electric push rod 42 pulls the first rotating shaft 432, the first rotating shaft 432 drives the base 431 and the connecting rod 411 to realize the arc swing of the front baffle 41. In this process, the connecting rod 411 is also tilted at the same time. At the same time, when the first rotating shaft rises, it elastically pulls the spring 22 at the same time, so that the arc swing of the front baffle 41 is more stable and reduces vibration.

[0024] Furthermore, the top of the electric push rod 42 is rotatably connected to a third rotating shaft 6, and the third rotating shaft 6 is rotatably connected to a rotating seat 61, and the top of the rotating seat 61 is connected to the bottom of the chassis of the sweeper body 1. Specifically, when the electric push rod 42 pushes or pulls the connecting rod 411, the electric push rod 42 will also rotate along the third rotating shaft 6 and tilt, and the tilt angle will continue to change. By setting the third rotating shaft 6, the front baffle 41 can be swung in an arc more smoothly, achieving a better operation effect.

[0025] Furthermore, the cab of the sweeper body 1 is provided with a steering wheel 11, and the steering wheel 11 is provided with a paddle 12 for controlling the electric push rod 42. Specifically, a control module is provided in the steering wheel 11, and the paddle 12 is connected to the control module, and the other end of the control module is connected to the electric push rod 42. When the user paddles the paddle 12, the electric push rod 42 is controlled to pull the front baffle 41 upwards, and when the user releases the paddle 12, the electric push rod 42 pushes the front baffle 41 to reset, and the operation is simple and convenient.

[0026] Working principle: Under normal use, the front baffle plate 41 covers the front of the cleaning roller brush 3 to limit the dust in the roller brush cover 2 from being blown out; when the sweeper encounters large garbage, the electric push rod 42 pulls the lifting point 43, and the lifting point 43 drives the connecting rod 411 and the front baffle plate 41 to swing in a fan shape with the rotating fulcrum 21 as the rotation center, and the connecting rod 411 swings upward, while driving the front baffle plate 41 to swing upward and in an arc shape away from the cleaning roller brush 3. In this process, the garbage is first pushed by the front baffle plate 41 to continue to move forward, and as the front baffle plate 41 swings upward in an arc shape, the garbage gradually moves toward the direction of the cleaning roller brush 3. When the front baffle plate 41 is completely swung to the top, the garbage is swept into the garbage bin by the cleaning roller brush 3 to achieve a cleaning effect; compared with the front baffle plate 41 in the prior art, the front baffle plate 41 of the technical solution will gradually move toward the direction of the cleaning roller brush 3 when the garbage contacts the cleaning roller brush 3, has a certain buffering effect, a simple structure, fewer steps during operation of the front baffle plate 41, and higher operation efficiency.
