Abstract
Description
Technical Field
[0001] This application relates to sweeper trucks, and more particularly to a telescopic adjustment device suitable for sweeper trucks. Background Technology
[0002] The sweeper truck is equipped with four brushes, a water spray system, and a garbage collection device on both sides. As the vehicle moves forward, the brushes rotate to sweep away garbage on the ground, while the water spray system sprays water to suppress dust. However, the existing sweeper truck's cleaning system can only be controlled by its lifting mechanism, resulting in a fixed cleaning width. The cleaning range is limited to the area under the vehicle, making it impossible to effectively clean longer stretches of road or corners. The lack of adjustable cleaning width also hinders efficiency. Summary of the Invention
[0003] To solve the above problems, the technical solution of this utility model is: a telescopic adjustment device suitable for a sweeper truck, comprising a mounting plate 1 installed at the bottom of the sweeper truck and a telescopic cylinder. The right end of the telescopic cylinder is fixedly installed at the right end of the mounting plate 1. The pull rod end of the telescopic cylinder is movably connected to the right end of a connecting plate. The left end of the connecting plate is movably connected to the bottom of the right side of a connecting seat. The connecting plate has a left-narrow and right-wide structure, and a lead screw seat is fixedly installed at its width-narrow junction. The lead screw seat is movably connected to the right end of the cylinder. The left end of the cylinder is movably connected to the upper middle part of the right side of the connecting seat. The left end of the connecting seat is fixedly connected to a mounting plate 2. A rotary motor is fixedly installed on the left side of the mounting plate 2. The rotary motor is fixedly connected to the sweeping brush. A sliding groove is horizontally provided from the middle to the left end of the mounting plate 1. The left end of the sliding groove is curved downwards in an arc. A sliding shaft that cooperates with the sliding groove is fixedly installed on the right end of the connecting plate.
[0004] In order to observe the contact between the sweeper and the ground in real time, a camera is fixedly installed at the bottom of the mounting plate, and the camera is connected to the display screen in the driver's cab.
[0005] Compared with the prior art, the beneficial effects of this utility model are: the extension and retraction of the sweeping brush can be controlled by the telescopic hydraulic cylinder, which can effectively adjust the sweeping width and improve the sweeping efficiency; the contact degree between the sweeping brush and the ground can be adjusted by the hydraulic cylinder, so that the sweeping effect is better.

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0012] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0013] exist Figure 1 A telescopic adjustment device suitable for a sweeper truck is disclosed, comprising a mounting plate 1 and a telescopic cylinder 2 installed at the bottom of the sweeper truck. The right end of the telescopic cylinder 2 is fixedly installed at the right end of the mounting plate 1. The pull rod end of the telescopic cylinder 2 is movably connected to the right end of a connecting plate 3. The left end of the connecting plate 3 is movably connected to the bottom of the right side of a connecting seat 7. The connecting plate 3 has a left-narrow and right-wide structure, and a lead screw seat 4 is fixedly installed at its width-narrow junction. The lead screw seat 4 is movably connected to the right end of a cylinder 6. The left end of the cylinder 6 is movably connected to the upper middle part of the right side of the connecting seat 7. The left end of the connecting seat 7 is fixedly connected to a mounting plate 8. A rotary motor 9 is fixedly installed on the left side of the mounting plate 8. The rotary motor 9 is fixedly connected to a sweeping brush 10. A sliding groove 11 is horizontally arranged from the middle to the left end of the mounting plate 1. The left end of the sliding groove 11 is curved downwards in an arc. A sliding shaft 5 that cooperates with the sliding groove 11 is fixedly installed on the right end of the connecting plate 3.
[0014] Furthermore, a camera 12 is fixedly installed on the bottom of the mounting plate 1, and the camera 12 is connected to the display screen in the driver's cab.
[0015] When the sweeping brush 10 needs to be extended during operation, the lever end of the telescopic cylinder 2 extends, pushing the connecting plate 3 to move to the right. The sliding shaft 5 on the connecting plate slides to the left in the sliding groove 11. When it slides to the curved section at the left end of the sliding groove 11, the sweeping brush 10 contacts the ground. At this time, the degree of contact between the sweeping brush 10 and the ground can be observed through the display screen in the cab connected to the camera 12. The contact between the sweeping brush 10 and the ground can be effectively adjusted by adjusting the extension and retraction length of the cylinder 6.
[0016] When not in operation, the rod end of the telescopic cylinder 2 retracts, causing the connecting plate 3 to move to the right, and the slide 5 slides to the right within the slide 11 until it is retracted.
[0017] This invention allows the mounting plate to be directly fixed onto the existing lifting device. Through the cooperation of the lifting device and the hydraulic cylinder 6, it can operate normally even when not extended. Adding this device effectively expands the cleaning range and improves cleaning efficiency.
[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
