Description

Technical Field

[0001] This utility model relates to the field of sweeper technology, specifically to a sweeper cleaning structure. Background Technology

[0002] Sweeper trucks, as sanitation vehicles that integrate road sweeping and washing functions, are widely used in daily cleaning operations on urban roads, highways, and industrial parks. Their core function relies on a rational sweeping structure layout and efficient control methods to effectively collect and clean up road debris under different working conditions.

[0003] However, traditional structures are mostly fixed or single-sided adjustable, making it inconvenient to adjust the sweeping range and complex to operate. This makes them difficult to adapt to different road environments and operational needs, affecting the equipment's flexibility and operational efficiency. Therefore, a new sweeping structure for a sweeper truck is proposed to solve these problems. Utility Model Content

[0004] This utility model provides a sweeping structure for a sweeper vehicle, which solves the problem of poor flexibility of existing structures by synchronously or independently adjusting the movement direction of the sweeping structures on both sides through a single control structure.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a sweeping structure for a sweeper, and a mounting bracket installed at the bottom of the sweeper;

[0006] The moving mechanism consists of two symmetrically arranged at the bottom of the mounting frame. It includes two symmetrically arranged mounting plates, with two sliding limit rods and a rotatable lead screw between the two mounting plates. The sliding limit rods and the lead screw are fitted with moving seats, and the moving seats are threaded onto the outside of the lead screw. The opposite ends of the two lead screws both pass through the mounting plates.

[0007] The adjustable transmission mechanism includes a transmission mechanism mounted on a mounting bracket, and a sliding driven mechanism is provided on the opposite ends of the two lead screws. The sliding driven mechanism can be connected to or disconnected from the transmission mechanism by sliding.

[0008] There are two cleaning units, each mounted on a mobile base of a mobile mechanism.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the transmission mechanism includes two support seats disposed on the top of the mounting frame, a rotating shaft rotatably disposed between the two support seats, two transmission gears disposed on the outside of the rotating shaft, an opening provided on the mounting frame for the transmission gears to pass through, a drive device disposed on the top of the mounting frame, and the rotating shaft passing through the support seats and connected to the output shaft of the drive device.

[0011] Furthermore, the sliding driven mechanism includes a driven gear slidably disposed on the opposite end of the lead screw, the driven gear being adapted to a corresponding transmission gear, a plurality of sliding grooves being provided on the opposite end of the lead screw, a sliding block being provided on the inner ring of the driven gear and slidingly engaging with the sliding groove, and a telescopic spring being fitted on the outside of the opposite end of the lead screw between the driven gear and the mounting plate.

[0012] Furthermore, the sliding driven mechanism also includes a gear pressing mechanism disposed between the two moving mechanisms. This mechanism includes a support plate disposed between the bottom of the mounting plates at opposite ends of the two moving mechanisms. The top of the support plate is provided with two first telescopic cylinders corresponding to the two driven gears respectively. The telescopic end of the first telescopic cylinder is provided with a pressure plate that can abut against the driven gear.

[0013] Furthermore, the cleaning body includes a vertical slide seat located at the bottom of the movable seat, on which a vertical sliding part is slidably mounted. A second telescopic cylinder is provided on both sides of the movable seat. The telescopic end of the second telescopic cylinder is connected to the vertical sliding part. A fixing rod is installed on the vertical sliding part, and the other end of the fixing rod is connected to a self-driving cleaning brush.

[0014] Furthermore, one or both sides of the fixed rod are provided with diagonal rods, and the other end of the diagonal rods is connected to a side self-driving cleaning brush.

[0015] Furthermore, the inclined rod is hinged to the fixed rod, and a third telescopic cylinder is provided between the inclined rod and the fixed rod, with both ends of the third telescopic cylinder being hinged to the inclined rod and the fixed rod respectively.

[0016] Furthermore, the fixing rod is connected to the vertical sliding part by bolts, and the connection end between the fixing rod and the vertical sliding part is provided with reinforcing ribs.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] 1. The sweeping structure of this sweeper truck, through the setting of an adjustable transmission mechanism, enables synchronous or independent control of the sweeping structures on both sides of the sweeper truck, which greatly improves the flexibility and adaptability of operation. It can flexibly adjust the sweeping range according to the actual road conditions, and can efficiently deal with both narrow areas and roadside debris. At the same time, it uses a single drive device to realize the linkage or independent operation of the two sweeping structures, which simplifies the transmission system, improves the integration and response speed of the control system, and reduces maintenance costs and failure rate.

[0019] 2. The sweeper's cleaning structure features height and angle adjustment capabilities, and is equipped with a main sweeping brush and side sweeping brushes, significantly expanding the cleaning coverage area. The design of the vertical sliding base and vertical sliding part allows the height of the sweeping brushes to be flexibly adjusted according to ground conditions, ensuring optimal cleaning results in different terrains. Simultaneously, the hinged design between the fixed rod and the diagonal rod, combined with the adjustment function of the third telescopic cylinder, allows for angle changes in the side self-driving sweeping brushes, further enhancing the comprehensiveness and thoroughness of the cleaning. Furthermore, the sweeping unit can be retracted entirely to the bottom of the vehicle when not in operation, effectively reducing space occupation and preventing collision damage during driving.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figure 1-7 As shown in the figure, the sweeping structure of a sweeper in this embodiment includes: a mounting frame 1, a moving mechanism 2, an adjustable transmission mechanism 3, and a sweeping body 4.

[0031] Mounting bracket 1 is installed at the bottom of the sweeper truck, and space needs to be reserved at the bottom of the sweeper truck for its installation.

[0032] There are two moving mechanisms 2, symmetrically arranged at the bottom of the mounting bracket 1, with a gap between them to facilitate the installation of the adjustable transmission mechanism 3. Specifically, each mechanism includes two symmetrically arranged mounting plates 201. Between the two mounting plates 201 are two sliding limit rods 202 and a rotatable lead screw 203. The sliding limit rods 202 are fixed to both sides of the lead screw 203, which is rotatably mounted between the two mounting plates 201 via bearings. A moving seat 204 is fitted over the sliding limit rods 202 and the lead screw 203, threaded onto the outside of the lead screw 203. The moving seat 204 has two holes for the sliding limit rods 202 to pass through and one threaded hole for threaded engagement with the lead screw 203. The opposite ends of the two lead screws 203 both pass through the mounting plates 201. Additionally, as... Figure 4 The opposite ends of the two lead screws 203 shown are both smooth surfaces without threads.

[0033] The adjustable transmission mechanism 3 includes a transmission mechanism 31 mounted on the mounting bracket 1. Each of the two lead screws 203 has a sliding driven mechanism 32 at its opposite end. The sliding driven mechanism 32 can be connected or disconnected from the transmission mechanism 31 by sliding, so that the transmission mechanism 31 can drive both moving mechanisms 2 at the same time or drive only one moving mechanism 2, thus achieving a flexible adjustment effect.

[0034] The transmission mechanism 31 includes two support seats 310 disposed on the top of the mounting frame 1. A rotating shaft 311 is rotatably disposed between the two support seats 310. The rotating shaft 311 is rotatably disposed between the two support seats 310 via bearings. Two transmission gears 312 are disposed on the outside of the rotating shaft 311. An opening 101 is provided on the mounting frame 1 for the transmission gears 312 to pass through. A drive device 313 is also disposed on the top of the mounting frame 1. The drive device 313 consists of a motor and a drive motor. The rotating shaft 311 passes through the support seats 310 and is connected to the output shaft of the drive device 313.

[0035] With this design, the two transmission gears 312 can be driven to rotate simultaneously by the drive device 313. Since the transmission mechanism 31 is set on the top of the mounting frame 1 in this embodiment, corresponding space needs to be reserved at the bottom of the sweeper truck during installation.

[0036] In addition, the sliding driven mechanism 32 includes a driven gear 320 slidably disposed on the opposite end of the lead screw 203. The driven gear 320 is adapted to the corresponding transmission gear 312. The driven gear 320 achieves engagement or disengagement with the transmission gear 312 by sliding on the opposite end of the lead screw 203. The opposite end of the lead screw 203 is provided with a plurality of sliding grooves 321. The inner ring of the driven gear 320 is provided with a sliding block 322 that slides in cooperation with the sliding grooves 321. In this embodiment, there are four sliding grooves 321 and four sliding blocks 322, which allows the driven gear 320 to drive the lead screw 203 to rotate while sliding on it. The outer side of the opposite end of the lead screw 203 is fitted with a telescopic spring 323 located between the driven gear 320 and the mounting plate 201. The driven gear 320 can maintain the meshing state with the transmission gear 312 under the tension of the telescopic spring 323 to achieve transmission connection.

[0037] The sliding driven mechanism 32 also includes a gear pressing mechanism disposed between the two moving mechanisms 2. It includes a support plate 324 disposed between the bottom of the mounting plates 201 at opposite ends of the two moving mechanisms 2. The top of the support plate 324 is provided with two first telescopic cylinders 325 respectively corresponding to the two driven gears 320. The telescopic end of the first telescopic cylinder 325 is provided with a pressure plate 326 that can abut against the driven gear 320. The first telescopic cylinder 325 can be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder.

[0038] With this design, the extension and retraction of the first telescopic cylinder 325 can control the pressure plate 326 to push the driven gear 320, thereby disengaging it from the transmission gear 312 and terminating the transmission connection between the two. At the same time, the pressure plate 326 can also be disengaged from the driven gear 320, allowing the driven gear 320 to reset under the action of the telescopic spring 323 and mesh with the transmission gear 312.

[0039] There are two cleaning bodies 4, which are respectively installed on the moving bases 204 of the two moving mechanisms 2.

[0040] With this design, the two sliding driven mechanisms 32 can be connected or disconnected from the drive device 313 respectively, so that one drive device 313 can drive two or any one of the sweeping bodies 4 to move at the same time. This greatly improves the flexibility of the sweeping body 4 in dealing with different road conditions, while also effectively reducing the transmission structure and improving the centralization of the control end.

[0041] In a preferred embodiment, the cleaning body 4 includes a vertical slide 401 disposed at the bottom of the movable seat 204. A vertical sliding part 402 is slidably mounted on the vertical slide 401, so that the vertical sliding part 402 can slide vertically on the vertical slide 401. A second telescopic cylinder 403 is disposed on both sides of the movable seat 204. The second telescopic cylinder 403 can be an electric cylinder or a hydraulic cylinder. The telescopic end of the second telescopic cylinder 403 is connected to the vertical sliding part 402, so that the vertical sliding part 402 can be controlled to slide vertically by the second telescopic cylinder 403. A fixing rod 404 is installed on the vertical sliding part 402, and the other end of the fixing rod 404 is connected to a self-driving cleaning brush 405.

[0042] With this design, the vertical sliding part 402 can be used to adjust the height of the self-driving cleaning brush 405. In addition, the self-driving cleaning brush 405 is existing technology in the field, so it will not be described in detail here.

[0043] In a preferred embodiment, the fixed rod 404 is provided with a diagonal rod 406 on one or both sides, and the other end of the diagonal rod 406 is connected to a side self-driving cleaning brush 407, thereby forming multiple cleaning brush structures and increasing its cleaning range.

[0044] Furthermore, the inclined rod 406 is hinged to the fixed rod 404, and a third telescopic cylinder 408 is provided between the inclined rod 406 and the fixed rod 404. The third telescopic cylinder 408 can be an electric cylinder or a hydraulic cylinder, and both ends of the third telescopic cylinder 408 are respectively hinged to the inclined rod 406 and the fixed rod 404.

[0045] With this design, the cleaning angle of the self-driving sweeping brush 407 on the telescopic side can be adjusted by the telescopic adjustment of the third telescopic cylinder 408, thereby achieving comprehensive cleaning within a certain range. At the same time, when the sweeping body 4 is retracted into the sweeper, it can be retracted to the side of the fixed rod 404.

[0046] Furthermore, the fixing rod 404 is connected to the vertical sliding part 402 by bolts, and a reinforcing rib 409 is provided at the connection end between the fixing rod 404 and the vertical sliding part 402.

[0047] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
