Description

Technical Field

[0001] The present invention belongs to the technical field of sweepers, and in particular relates to a multifunctional sweeping device and a sweeper. Background Art

[0002] As a common sanitation vehicle, a road sweeper is widely used in cleaning garbage on the surface of roads or sites. However, the cleaning mechanisms of most existing road sweepers only clean and spray dust on the road surface, but cannot clean the curbstones. As a result, some dust and debris on the curbstones are blown onto the road, resulting in incomplete cleaning of road garbage.

[0003] Some of the existing sweepers are also equipped with a separate curbstone cleaning mechanism, which can achieve both ground cleaning and curbstone cleaning. However, the curbstone cleaning mechanism and the ground cleaning mechanism are independently set, which invisibly increases the number and configuration of sweeping brushes. On the one hand, it leads to high manufacturing costs and high maintenance costs. On the other hand, it is not convenient to arrange the cleaning mechanism at the bottom of the frame, and the use effect is not ideal. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multifunctional cleaning device which has a reasonable structural design and adopts a set of sweeping brush mechanisms to realize both ground cleaning and roadside cleaning.

[0013] A locking mechanism is provided between the rotating arm and the rotating seat, and is used to lock the sweeping brush mechanism after rotation adjustment, so that the sweeping brush mechanism is fixed in the ground cleaning working position or the curbstone cleaning working position;

[0014] The lifting drive mechanism drives the longitudinal arm to lift and lower so as to adjust the height between the sweeping mechanism and the ground.

[0015] As a preferred technical solution, a sleeve is provided at the end of the longitudinal arm, the transverse arm is inserted into the sleeve, a positioning pin is provided between the transverse arm and the sleeve, a torsion spring is sleeved on the positioning pin, one arm of the torsion spring abuts against the transverse arm, and the other arm of the torsion spring abuts against the longitudinal arm.

[0016] As a preferred technical solution, a rotating hole is provided on the rotating seat, and a rotating pin which can be inserted into the rotating hole is fixedly provided on the sweeping brush mechanism.

[0017] As a preferred technical solution, the rotating arm is L-shaped.

[0032] The present invention will be further described below with reference to the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. It is understood that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0033] like Figure 1 As shown, the sweeper includes a frame 10, and multifunctional sweeping devices 20 are respectively installed on both sides of the bottom of the frame 10;

[0034] refer to Figure 2 and Figure 3 The multifunctional cleaning device 20 includes a fixed seat 21, which is used to be fixedly connected to the vehicle frame; the fixed seat 21 is hingedly provided with a longitudinal arm 22, and the longitudinal arm 22 is arranged along the traveling direction of the vehicle; the end of the longitudinal arm 22 is provided with a sleeve 221, and a cross arm 23 is inserted in the sleeve 221, and a positioning pin shaft 222 is provided between the cross arm 23 and the sleeve 221, and a torsion spring 223 is sleeved on the positioning pin shaft 222, and one arm of the torsion spring 223 abuts against the cross arm 23, and the other arm of the torsion spring 223 abuts against the longitudinal arm 22, so as to ensure that the cross arm has a certain automatic obstacle avoidance floating ability, and ensure that the sweeping mechanism at the end of the cross arm can automatically float elastically when encountering an obstacle, thereby improving the working life.

[0035] refer to Figure 3 A fixed plate 24 is fixedly mounted on one side of the outer end of the cross arm 23 , and an arc-shaped hole 241 is opened on the fixed plate 24 . A rotating seat 231 is fixedly mounted on the outer end of the cross arm 23 .

[0036] refer to Figure 2 and Figure 4 The sweeping mechanism 25 is fixedly provided with an L-shaped rotating arm 251, and the sweeping mechanism 25 is rotatably mounted on the rotating seat 231. Rotating the sweeping mechanism 25 can switch the sweeping mechanism between the ground cleaning working position and the curbstone cleaning working position;

[0037] A locking mechanism is provided between the rotating arm 251 and the rotating base 231. The locking mechanism is used to lock the sweeping brush mechanism 25 after rotational adjustment, thereby securing the sweeping brush mechanism 25 in the floor cleaning or curbstone cleaning position. In this embodiment, the locking mechanism is a locking bolt 26 inserted into the arc-shaped hole 241. Loosening the locking bolt 26 allows the sweeping brush mechanism 25 to be rotated and adjusted to the desired position. Once the position is reached, tightening the locking bolt 26 secures the sweeping brush mechanism 25, providing simple and convenient operation.

[0038] refer to Figure 3 and Figure 4 In this embodiment, the rotating arm 251 is L-shaped; the rotating seat 231 is provided with a rotating hole 232, and the sweeping mechanism 25 is fixedly provided with a rotating pin 252 that can be inserted into the rotating hole 232. The fixed plate 24 is fan-shaped, with a clearance opening 242 formed at the bottom of the fixed plate 24. The L-shaped rotating arm 251 cooperates with the fan-shaped fixed plate 24 with the clearance opening 242, thereby enabling quick rotation and adjustment of the sweeping mechanism 25 within the limited space at the bottom of the vehicle frame. Furthermore, the clearance opening 242 at the bottom of the fixed plate 24 facilitates removal, replacement, and maintenance of the sweeping mechanism 25 in the event of a malfunction.

[0039] Refer again Figure 3 The multifunctional cleaning device 20 further includes a lifting drive mechanism for driving the longitudinal arm 22 to move up and down, thereby adjusting the height of the sweeping mechanism 25 relative to the ground. In this embodiment, the lifting drive mechanism is an electric push rod 27. A push rod seat is fixedly provided on the longitudinal arm 22. One end of the electric push rod 27 is hinged to the fixed seat 21, and the other end of the electric push rod 27 is hinged to the push rod seat.

[0040] refer to Figure 5 and Figure 6The operating principle of the present invention is as follows: The electric push rod 27 telescopically moves, driving the longitudinal arm 22 and the transverse arm 23 to adjust the height of the sweeping brush mechanism 25 relative to the ground. Either the ground cleaning mode or the curb cleaning mode can be selected according to work needs. To switch operating modes, the locking bolt 26 is loosened and an external force is applied to the sweeping brush mechanism 25. Under the action of the external force, the sweeping brush mechanism 25 rotates around the rotating pin 252 to the appropriate position. The locking bolt 26 is then tightened to secure the rotating arm 251 to the fixed plate 24, and the sweeping operation can begin. In this way, a single sweeping brush mechanism 25 can achieve both ground and curb cleaning. The number of sweeping brushes and the number of configurations are reduced, which not only reduces manufacturing costs and maintenance expenses, but also facilitates the placement of the sweeping brush mechanism at the bottom of the vehicle frame, resulting in better performance.

[0041] By arranging a fixed plate 24 on the cross arm 23, a rotating seat 231 and a rotating arm 251 on the sweeping and brushing mechanism 25, the sweeping and brushing mechanism can be cleverly switched between the ground cleaning working position and the roadside stone cleaning working position. The structural design is clever and reasonable, the operation is convenient, and the working angle of the sweeping and brushing mechanism is adjustable, which can be suitable for cleaning operations of various roadbed stones.

[0042] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
