Description

Technical Field

[0001] This utility model relates to the technical field of sweeper functional modules, and particularly to a sweeper anti-collision cleaning module. Background Technology

[0002] As is well known, in the existing technology of sweeper vehicles, the cleaning module is mostly fixed to the front of the vehicle using a fixed structure. In operation, the sweeper vehicle drives the entire cleaning module to move on the ground, thereby cleaning surface debris. However, with the increasing demand for sweeping equipment in the market, various functional requirements have also been raised by the increasing number of clients. For example: 1. In the existing technology, this type of cleaning module may collide with hard or fixed objects due to improper operation or inadequate observation, causing the entire cleaning module to malfunction or even become unusable; 2. In the existing technology, the working end of this type of cleaning module is usually fixed to the bottom of the module, and its cleaning working width is constant during cleaning, making it impossible to adjust the cleaning width according to actual needs.

[0003] In view of the various drawbacks of the existing technology, the urgent technical problem to be solved by those skilled in the art is how to improve the technology and design a sweeper cleaning module with anti-collision protection and automatic adjustment of the working surface width. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model aims to develop a sweeper anti-collision cleaning module, which achieves anti-collision and traction protection through an elastic traction structure at the front end, and realizes the left and right lateral movement of two evenly distributed cleaning modules through a lateral movement drive module.

[0005] The technical solution adopted is as follows: A sweeper anti-collision cleaning module includes a lateral guide section, a sliding module movably fixed on the lateral guide section, a hinge seat on the sliding module, a lifting link connected to the hinge seat, a motor mounting base connected to the end of the lifting link, a cleaning motor fixed on the motor mounting base, and a cleaning brush at the bottom of the cleaning motor; a lateral drive device is provided at the front end of the vehicle body in conjunction with the lateral guide section; a positioning screw is provided between the lifting link and the hinge seat, and an elastic tension member is provided between the two in conjunction with the positioning screw.

[0006] The lifting linkage is a four-bar structure, which includes a vertical bar I, a vertical bar II, a horizontal bar I, and a horizontal bar II; a lifting drive device is installed inside the four-bar linkage or a lifting traction device is installed outside the four-bar linkage.

[0007] The lateral guide section adopts a guide rod that protrudes from the vehicle body. By setting the guide rod that protrudes from the vehicle body, it is possible to avoid the accumulation of impurities on the lateral guide section during external cleaning, thus avoiding blockage when the sliding module moves laterally.

[0008] The vehicle body has a lateral drive clearance groove on the front side, a lateral drive compartment inside the vehicle body, and a lateral drive device inside the lateral drive compartment.

[0009] Both the lifting drive device and the lateral drive device use electric actuators, which can be connected to the power supply module inside the vehicle body without the need for additional energy supply.

[0010] A transition connecting seat is provided between the lifting link and the motor mounting base. The transition connecting seat is provided with an adjustment groove, which allows for vertical and horizontal adjustment of the motor mounting base.

[0011] The beneficial effects of this utility model are as follows: A sliding module is movably fixed on the transverse guide section of this utility model. A hinge seat is provided on the sliding module, and a lifting link is connected to the hinge seat. A motor mounting seat is connected to the end of the lifting link, and a sweeping motor is fixed on the motor mounting seat. A cleaning brush is provided at the bottom of the sweeping motor. A transverse drive device is provided at the front end of the vehicle body in conjunction with the transverse guide section. The transverse drive device can drive the two sets of sweeping motors and cleaning brushes to move laterally, thereby adjusting the sweeping area. A positioning screw is provided between the lifting link and the hinge seat. An elastic tension member is provided between the two in conjunction with the positioning screw. The swing position of the sweeping motor and cleaning brush can be realized through the positioning screw. When the cleaning brush or the motor mounting seat touches the outside, the lifting link together with the motor mounting seat overcomes the tension of the elastic tension member and swings backward, thereby achieving buffering and avoiding damage or even scrapping of the entire sweeping module.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0014] As shown in the attached diagram, a sweeper anti-collision cleaning module is integrally disposed at the front or rear end of the vehicle body 1; it includes a lateral guide portion, on which a sliding module 2 is movably fixed. The lateral guide portion can be a guide groove or a raised track. In this embodiment, the lateral guide portion is a guide rod 11 protruding from the vehicle body 1, such as... Figure 1 As shown, there are two guide rods 11 spaced apart. The two guide rods 11 are supported by several support seats 12. By setting the guide rods 11 in a way that protrudes from the vehicle body 1, it can prevent impurities from accumulating on the transverse guide part during external cleaning, thus avoiding blockage when the sliding module 2 moves transversely.

[0015] The sliding module 2 is provided with a hinge seat 22, and a lifting link 4 is connected to the hinge seat 22. In this embodiment, the lifting link 4 is a four-bar structure, such as... Figure 4As shown, it includes a vertical rod I 42, a vertical rod II 45, a horizontal rod I 43, and a horizontal rod II 44; the vertical rod I 42 is movably connected to the hinge seat 22; the end of the lifting link 4 is the vertical rod II 45, and a motor mounting seat 51 is connected to the vertical rod II 45. A sweeping motor 5 is fixed on the motor mounting seat 51, and a disc-shaped cleaning brush 52 is provided at the bottom of the sweeping motor 5; those skilled in the art can set a lifting drive device inside the lifting link 4 or a lifting traction device outside the lifting link 4; in this embodiment, since the lifting link 4 is a four-bar structure, a lifting drive electric push rod 41 is set at the center of the four-bar structure as a lifting drive device, which can realize the overall lifting of the sweeping motor 5 and the cleaning brush 52, and the working state of the cleaning brush 52 can be adjusted through this lifting action. Those skilled in the art can also install a vertical steel cable at one end of the vertical rod II 45 of the lifting linkage 4 or on the motor mounting base 51, and lift the sweeping motor 5 and the cleaning brush 52 as a whole by pulling the vertical steel cable by the operator in the cab, thereby adjusting the working state of the cleaning brush 52 through this lifting action.

[0016] This utility model features a lateral movement drive device at the front end of the vehicle body, in conjunction with the guide rod 11. Specifically, the front side of the vehicle body 1 has a lateral movement clearance groove 13, and the interior of the vehicle body has a lateral movement drive compartment 14. A lateral movement electric actuator 15 is installed within the lateral movement drive compartment 14 as the lateral movement drive device. A drive seat 21 is welded onto the sliding module 2, and the drive seat 21 is connected to the drive end of the lateral movement electric actuator 15, thereby achieving lateral guidance and drive of the sliding module 2 on the guide rod 11. This drive enables the extension and retraction adjustment of the working width of the cleaning brush 52.

[0017] This utility model also solves the following technical problems: a positioning screw 3 is provided between the lifting link 4 and the hinge seat 22. An adjustment positioning plate 31 is welded to the hinge seat 22, and the positioning screw 3 is provided through the adjustment positioning plate 31. A positioning nut is provided on the positioning screw 3. With this design, the swing angle between the lifting link 4 and the hinge seat 22 can be adjusted by the positioning screw 3. After the adjustment is completed, an elastic tension member is provided between the lifting link 4 and the hinge seat 22 in conjunction with the positioning screw 3. In this embodiment, a tension spring 6 is used to pull in the opposite direction of the positioning screw 3. When the vehicle is moving and comes into contact with an external foreign object, the external object pushes the entire motor fixing seat 51 to move backward. The tension spring 6 can buffer the movement and avoid causing the entire sweeping module to malfunction or even be scrapped.

[0018] This invention uses electric actuators for both the lifting drive device and the lateral drive device, which can be connected to the power supply module inside the vehicle body, eliminating the need for additional energy supply and making it more convenient to use.

[0019] To further improve the installation accuracy and flexibility of this utility model, a transition connecting seat 46 is provided between the lifting link 4 and the motor mounting base 51. The transition connecting seat 46 is provided with an adjustment groove, which can be vertical or horizontal, so as to realize the vertical and horizontal adjustment of the motor mounting base 51.

[0020] In summary, this utility model, by providing a transverse electric actuator 15 within the transverse drive chamber 14 as a transverse drive device, drives the entire sliding module 2, lifting linkage 4, and sweeping motor 5 to move transversely in linkage, enabling the extension and retraction adjustment of the working width of the cleaning brush 52, suitable for different sweeping conditions. Furthermore, by providing a positioning screw 3 and a tension spring 6 between the lifting linkage 4 and the hinge seat 22, the working angle between the two can be adjusted by the positioning screw 3, and the tension spring 6 achieves frontal traction of the entire lifting linkage 4 and sweeping motor 5 assembly. When encountering foreign objects, the entire lifting linkage 4 and sweeping motor 5 assembly must overcome the pulling force of the tension spring 6 when swinging backward, which can achieve a certain degree of buffering and prevent malfunction of the entire working part.
