Description

Technical Field

[0001] This utility model relates to the technical field of sweeper and scrubber vehicle components, specifically to a high-pressure spray washing device for sweeper and scrubber vehicles. Background Technology

[0002] Chinese patent document CN222525280U discloses a high-pressure spray washing device for sweeper trucks, including a clean water tank and a spray washing mechanism. This high-pressure spray washing device is equipped with a three-way pipe, a first solenoid valve, a second solenoid valve, a DC nozzle, and a spray head. When heavy washing is required, the first solenoid valve opens and the second solenoid valve closes, allowing the mixed liquid to be sprayed from the DC nozzle, quickly removing stubborn stains and loose debris. When light washing is required, the first solenoid valve closes and the second solenoid valve opens, allowing the mixed liquid to be sprayed from the spray head for even coverage and light cleaning, or for situations requiring moistening without strong rinsing. The two nozzles can be used together to handle a wider range of cleaning tasks. The high-pressure spray washing device also includes an additive pump and a water pump. The additive pump and water pump work to deliver additives and water into a mixing tank for mixing, improving cleaning efficiency. An impeller frame and a mixing impeller are also included, with water flowing through the mixing impeller to rotate it. Since sweepers typically operate on dirty roads or in polluted areas, when high-pressure water is sprayed through the spray nozzles, especially direct-flow nozzles, to wash the ground, it is easy to splash mud, oil, or other particles onto the bottom of the turntable. As a result, the splashed liquid and dirt tend to adhere to the bottom of the turntable. Utility Model Content

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example

[0024] The present invention will now be further described with reference to the accompanying drawings.

[0025] like Figures 1 to 4 As shown, this embodiment provides a high-pressure spray washing device for a sweeper truck, including a turntable 10 and a spray washing mechanism 11 installed at the bottom of the turntable 10. A rotating motor 12 is installed at the top of the turntable 10. The turntable 10 is square in shape. Two sets of protective cover assemblies 13 are symmetrically installed on the turntable 10 with the spray washing mechanism 11 as the center. When the protective cover assembly 13 is flipped to the bottom of the turntable 10, the splashes washed by the spray washing mechanism 11 adhere to the surface of the protective cover assembly 13. When the protective cover assembly 13 is flipped to the top of the turntable 10, the scraper assembly 14 scrapes away the splashes adhering to the surface of the protective cover assembly 13.

[0026] The working principle and beneficial effects of the above technical solution are as follows:

[0027] This utility model discloses a high-pressure spray washing device for a sweeper truck. When the spray washing mechanism 11 washes the ground, the protective cover assembly 13 operates, and the two sets of protective cover assemblies 13 simultaneously flip to below the turntable 10. The splashes from the spray washing mechanism 11 adhere to the surface of the protective cover assembly 13, thereby reducing the risk of the bottom of the turntable 10 being splashed with splashes. After the spray washing mechanism 11 stops working, the two sets of protective cover assemblies 13 simultaneously flip to above the turntable 10, and the scraper assembly 14 scrapes off the splashes adhering to the surface of the protective cover assembly 13. This achieves the purpose of cleaning the splashes adhering to the surface of the protective cover assembly 13. The high-pressure spray washing device for a sweeper truck provided by this utility model protects the bottom of the turntable 10 from the adhesion of splashes as much as possible.

[0028] In one embodiment, two sets of protective cover assemblies 13 are distributed at both ends of the turntable 10 along its length, and the spraying mechanism 11 is distributed on the center line of the turntable 10 along its width.

[0029] The beneficial effects of the above technical solution are as follows:

[0030] When the two sets of protective cover assemblies 13 are flipped synchronously to the bottom of the turntable 10, they are symmetrically distributed with the spray washing mechanism 11 located on the center line of the width direction of the turntable 10 as the center, thus realizing the reasonable layout of the protective cover assemblies 13 and the spray washing mechanism 11 on the turntable 10.

[0031] In one embodiment, the protective shield assembly 13 includes:

[0032] Fixed shaft 15, two sets of fixed shaft 15 are installed opposite each other on the side end of turntable 10, and scraper assembly 14 is installed on fixed shaft 15;

[0033] Rotating sleeve 16, the rotating sleeve 16 is sleeved on the fixed shaft 15;

[0034] A pair of main rotating rods 17 are distributed opposite to each other on the side end of the turntable 10 and are respectively fixedly connected to the rotating sleeve 16;

[0035] The protective cover 18 is arranged in a three-sided enclosure and is fixedly installed on the main rotating rod 17. The protective cover 18 is open at the end near the turntable 10 and the end near the spray washing mechanism 11.

[0036] The working principle and beneficial effects of the above technical solution are as follows:

[0037] The protective cover 18 has a fan-shaped cross-section. When the protective cover 18 flips up and down, its inner wall slides at both ends of the turntable 10 along its length, thus preventing motion interference. The protective cover 18 rotates on the fixed shaft 15 around the main rotating rod 17 connected to it and the rotating sleeve 16 connected to the main rotating rod 17. When the protective covers 18 of the two sets of protective cover assemblies 13 flip synchronously to the bottom of the turntable 10, they form a semi-circular structure to protect the bottom of the turntable 10 as much as possible. When the protective covers 18 of the two sets of protective cover assemblies 13 flip synchronously to the top of the turntable 10, the surface of the protective cover 18 actively rubs against the scraper assembly 14, thereby scraping away the sputtered material adhering to the surface of the protective cover 18.

[0038] In one embodiment, the rotating sleeves 16 of the two sets of protective cover assemblies 13 are connected by a pair of meshing spur gears 19. The flip motor 20 is mounted on the top of the turntable 10, and the output end of the flip motor 20 is equipped with a spur gear 21, which is connected to one of the spur gears 19 in a transmission connection.

[0039] The working principle and beneficial effects of the above technical solution are as follows:

[0040] When the flip motor 20 operates, it drives the spur gear 21 installed at its output end to rotate. After the spur gear 21 drives one of the spur gears 19 meshing with it to rotate, the pair of spur gears 19 rotate synchronously, thereby realizing the up-and-down flipping action of the rotating sleeve 16 connected to the spur gear 19, the main rotating rod 17 installed on the rotating sleeve 16, and the protective cover 18 installed on the main rotating rod 17.

[0041] In one embodiment, the scraper assembly 14 includes a scraper 22 arranged in an arc shape, with both ends of the scraper 22 connected to a fixed shaft 15, the inner end of the scraper 22 abutting against a protective cover 18, and bristles 23 mounted on the inner end of the scraper 22.

[0042] The working principle and beneficial effects of the above technical solution are as follows:

[0043] The scraper 22 is distributed at both ends of the turntable 10 without moving via the fixed shaft 15. When the protective covers 18 of the two sets of protective cover assemblies 13 are flipped to the top of the turntable 10, the surface of the protective cover 18 actively rubs against the bristles 23 located at the inner end of the scraper 22, thereby scraping away the sputtered material attached to the surface of the protective cover 18.

[0044] In one embodiment, when the protective cover assembly 13 is flipped over to the top of the turntable 10, the main rotating rods 17 of the two sets of protective cover assemblies 13 form a V-shaped notch, and the mounting bracket is connected to the rotating motor 12 through the V-shaped notch and is mounted on the sweeper.

[0045] The working principle and beneficial effects of the above technical solution are as follows:

[0046] The V-shaped notch design facilitates the connection of the rotating motor 12 to the sweeper truck via the mounting bracket, and prevents movement interference when the protective cover 18 is flipped upwards.

[0047] In one embodiment, the surface of the protective cover 18 is coated with a hydrophobic coating.

[0048] The beneficial effects of the above technical solution are as follows:

[0049] The hydrophobic coating is made of silicon-based or fluoride coating to reduce the adhesion of sputtered material to the surface of the protective cover 18.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
