Description

Technical Field

[0001] This utility model relates to a sweeper, specifically a front-mounted sweeper with the sweeping components located at the front. Background Technology

[0002] A front-mounted sweeper is a type of vehicle where the frame extends forward and a sweeping component is installed at the front of the frame. This type of sweeper can clean the ground in front of the vehicle, avoiding the problem of dust and other debris being compacted and difficult to clean when the wheels are used as in a rear-mounted sweeper.

[0003] In existing front-mounted sweepers, the sweeping assembly is typically mounted rotatably at the front of the frame to lift it. A hydraulic cylinder or similar lifting device then flips the assembly upwards, lifting it off the ground. However, in this type of front-mounted sweeper, the rear of the sweeping assembly is too close to the ground, making it prone to colliding with stones or other debris on the road. Furthermore, this type of sweeper is susceptible to the sweeping assembly tilting forward or backward. Utility Model Content

[0004] The main purpose of this utility model is to provide a front-mounted sweeper to solve the problems in the prior art where the front part of the sweeping component is too close to the ground after it leaves the ground, and the sweeping component is prone to tilting.

[0027] Example 1

[0028] This embodiment provides a front-mounted sweeper, which includes a vehicle body 1. The vehicle body 1 includes a lower frame, and the front of the frame extends forward to form a sweeping mounting frame 2. The sweeping mounting frame 2 has uprights 3 on both sides. Upper connecting beams 11 can be provided at the upper ends of the two uprights 3. The two ends of the upper connecting beams 11 are respectively fixed to the upper parts of the two uprights 3, forming a structurally stable frame through the upper connecting beams 11, the two uprights 3, and the lower sweeping mounting frame 2. A lifting crossbeam 7 is provided between the two uprights 3. The two ends of the lifting crossbeam 7 are slidably connected to the two uprights 3. This slidable connection can be any slidable connection method in the prior art, such as guide rail connection, groove connection, or a collar fitted onto the uprights 3 for connection, etc. The lifting beam 7 is connected to a lifting device that drives the lifting beam 7 to move up and down. This lifting device is a drive structure that drives the lifting beam 7 to slide up and down along the column 3. This drive structure can be any device used to drive the components to move up and down along tracks such as slide rails, slides, or slide grooves, such as a cylinder, hydraulic cylinder, telescopic motor, or chain 6. For example, a telescopic device 10, such as a hydraulic cylinder or telescopic motor, drives the lifting beam 7 to move up and down. The telescopic device 10 can be directly installed on the vehicle body 1 or the column 3. The telescopic rod of the telescopic device 10 is connected to the lifting beam 7. The lifting of the telescopic device 10 can directly drive the lifting beam 7 to move up and down, or it can indirectly drive the lifting beam 7 to move up and down through a zipper or other means. Of course, the lifting beam 7 can also be connected to a ring-shaped chain 6. The chain 6 is driven to rotate by a sprocket, thereby driving the lifting beam 7 to move up and down. In this embodiment, a forward-extending sweeping component 8 is fixed to the lifting beam 7. The sweeping component 8 can be directly welded to the lifting beam 7, or indirectly welded or bolted to the lifting beam 7 via a connecting plate or connecting rod. The lifting beam 7 and the sweeping component 8 can be detachably or non-detachably fixed. Of course, this embodiment preferably uses a detachable connection method such as bolts. The sweeping component 8 is a conventional structure used in garbage sweepers, comprising an inverted housing containing a sweeping roller and a suction structure.

[0029] The front-mounted sweeper provided in this embodiment has a frame that extends forward to form a sweeping mounting frame 2 for connecting the sweeping assembly 8. Upward-extending columns 3 are provided on both sides of the mounting frame 2 to guide and support the vertical movement of the sweeping assembly 8. A lifting beam 7, positioned between the two columns 3, can slide up and down along the columns 3. This sliding connection can employ any existing technology such as guide rail connection, groove connection, or collar connection. A lifting device drives the lifting beam 7 to slide up and down. The sweeping assembly 8 is directly fixed or indirectly fixed to the lifting beam 7 via a connecting rod or connecting plate. When the lifting beam 7 moves up and down along the columns 3, it moves the sweeping assembly 8 up and down as a whole, enabling the sweeping assembly 8 to touch the ground or lift off the ground. The front-mounted sweeper provided by this invention, with the sweeping assembly 8 lifted as a whole, avoids the problem of the sweeping assembly 8 being too close to the ground in certain areas and the sweeping assembly 8 becoming tilted due to rotation.

[0030] Specifically, in this embodiment, the lifting device is formed by combining a chain 6 and a telescopic device 10. In this embodiment, an upper sprocket 4 is provided on the upper connecting beam 11, and a lower sprocket 5 is provided on the lower rear side of the column 3. A chain 6 is connected to the lifting beam 7. The chain 6 extends upward from the lifting beam 7 to the upper sprocket 4, crosses the upper connecting beam 11 and engages the upper sprocket 4, then extends downward to the lower sprocket 5, engaging the lower sprocket 5 and extending backward. The rear end of the chain 6 is connected to the telescopic device 10. The mounting base of the telescopic device 10 is located on both sides of the vehicle body 1, specifically on the lower sides of the driver's compartment. To avoid interference with the possible side doors, the telescopic device 10 can be located at the lower part of the door. The telescopic end of the telescopic device 10 extends forward and connects to the rear end of the chain 6.

[0031] More specifically, in this embodiment, the telescopic device 10 is a cylinder or a hydraulic cylinder, the cylinder body of the cylinder or hydraulic cylinder is fixed to the side of the vehicle body 1, and the telescopic end of the cylinder or hydraulic cylinder extends forward and is connected to the chain 6.

[0032] More specifically, in order to prevent the lifting beam 7 from tilting to the side and to improve the lifting power, the telescopic device 10, chain 6, upper sprocket 4 and lower sprocket 5 are provided in two sets and are symmetrically arranged on both sides of the vehicle body 1.

[0033] Specifically, the inner side of the column 3 is provided with a slot, and both ends of the lifting beam 7 are inserted into the slot.

[0034] More specifically, in order to further reduce the frictional resistance of the lifting beam 7, pulleys 9 are provided at both ends of the lifting beam 7, and the pulleys 9 roll in the slots.

[0035] Specifically, in this embodiment, the sweeping assembly 8 is provided with sweeping rollers; the rear of the vehicle body 1 is provided with a dust collection chamber, the dust collection chamber is connected to a dust collection pipe, and the dust collection pipe communicates with the interior of the housing.

[0036] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model and should be protected by the present utility model.
