[0001] This utility model belongs to the field of sweeper technology, specifically a front wheel structure for a sweeper. Background Technology

[0002] A sweeper truck is an integrated cleaning vehicle that combines sweeping and vacuuming. It boasts advantages such as high work efficiency, low cleaning costs, excellent cleaning results, and high safety performance, and is currently widely used in road cleaning. A rotating brush is installed at the front of the vehicle. As the vehicle moves forward, the brush carries garbage and sand from the ground to the center of the vehicle, where a vacuum suction head then sucks the garbage and sand into the waste collection bin.

[0003] In the existing technology, during the cleaning process, the front wheels of the sweeper will come into contact with various garbage, dust and dirt. If these dirt accumulate on the tire surface for a long time, it will not only affect the appearance of the tire, but may also cause corrosion of the tire surface and shorten the service life of the tire. Summary of the Invention

[0004] To address the shortcomings of existing technology and solve the problem that sweepers come into contact with various garbage, dust, and dirt during the sweeping process, and that if this dirt accumulates on the tire surface for a long time, it will not only affect the tire's appearance but may also cause tire surface corrosion and shorten the tire's lifespan.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The front wheel structure of the sweeper of this utility model includes a top plate, a pair of support plates fixedly connected to the bottom of the top plate, a wheel arranged between the support plates, and a scraping structure arranged on the pair of support plates, the scraping structure including:

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown in the figure, a front wheel structure of a sweeper according to an embodiment of the present invention includes a top plate 1, a pair of support plates 2 fixedly connected to the bottom of the top plate 1, a wheel 3 disposed between the support plates 2, and a scraping structure disposed on the pair of support plates 2. The scraping structure includes: a scraper assembly, including a first rectangular groove 4 opened on the side wall of the support plate 2, a scraper 5 placed in the first rectangular groove 4, a locking groove 6 opened at the bottom of the first rectangular groove 4, a pair of locking holes 7 opened on the scraper 5, and a locking assembly disposed in the locking groove 6 for fixing the scraper 5; a water spray assembly disposed at the bottom of the top plate 1 for washing the wheel 3; and a barrier assembly disposed at the bottom of the top plate 1 for blocking garbage.

[0025] During operation, the scraper 5 can remove the garbage attached to the wheel 3, thus preventing excessive garbage from affecting the wheel 3. This solves the problem in the prior art where, during the sweeping process, the front wheel of the sweeper comes into contact with various garbage, dust and dirt. If this dirt accumulates on the tire surface for a long time, it will not only affect the appearance of the tire, but may also cause corrosion of the tire surface and shorten the service life of the tire.

[0026] The positioning component includes a sliding groove 8 opened at the top of the first rectangular groove 4, a sliding block 9 fixed to the bottom of the sliding groove 8 by a spring 10, and a positioning block 11 fixed to the bottom of the sliding block 9.

[0027] The side wall of the support plate 2 is provided with a sliding groove 12, and an L-shaped block 13 is slidably connected in the sliding groove 12. The L-shaped block 13 is fixedly connected to the side wall of the sliding block 9 and is fixedly connected to the support plate 2 by screws 14.

[0028] During operation, the operator first places the scraper 5 into the first rectangular groove 4, aligning the locking hole 7 on the scraper 5 with the locking groove 6. Under the elastic force of the spring 10, the sliding block 9 moves downward along the sliding groove 8, causing the locking block 11 to insert into the locking hole 7 of the scraper 5, thus firmly fixing the scraper 5 in the first rectangular groove 4. If it is necessary to disassemble the scraper 5 for cleaning or replacement, simply loosen the screw 14, allowing the L-shaped block 13 to slide upward in the sliding through groove 12, causing the sliding block 9 and the locking block 11 to disengage from the locking hole 7 of the scraper 5, and the scraper 5 can be easily removed.

[0029] The water spray assembly includes a pair of rectangular plates 15 fixed to the bottom of the top plate 1. A water pump 16 is fixed between the opposite side walls of the pair of rectangular plates 15. The suction end of the water pump 16 is connected to a first connecting pipe 17, and the top of the first connecting pipe 17 penetrates the top of the top plate 1. The output end of the water pump 16 is connected to a second connecting pipe 18, and a high-pressure nozzle 19 is fixed to one end of the second connecting pipe 18.

[0030] During operation, the water pump 16 draws water from an external water source through the first connecting pipe 17, then pressurizes the water and delivers it to the high-pressure nozzle 19 through the second connecting pipe 18. The high-pressure nozzle 19 sprays water at high pressure to wash the wheels 3, effectively removing dust, mud, and other dirt from the surface of the wheels 3, preventing dirt from being carried into the sweeper's interior or contaminating other areas.

[0031] The barrier assembly includes a pair of support rods 20 fixed to the bottom of the top plate 1, a sliding plate 21 slidably connected to the pair of support rods 20, and a baffle 22 fixed to the bottom of the sliding plate 21.

[0032] An electric actuator 23 is fixedly connected to the bottom of the top plate 1, and the telescopic end of the electric actuator 23 is fixedly connected to the top of the sliding plate 21.

[0033] During operation, the position of the baffle 22 can be flexibly adjusted as needed to effectively prevent garbage from entering the interior of the sweeper or other areas, protecting the cleanliness and normal operation of the sweeper's interior, and reducing garbage on the path of the wheels 3, thus affecting its movement.

[0034] Working principle: The scraper 5 can scrape off the garbage attached to the wheel 3, avoiding excessive garbage from affecting the wheel 3. This solves the problem in the existing technology that when the sweeper is cleaning, the front wheel will come into contact with various garbage, dust and dirt. If these dirt accumulates on the tire surface for a long time, it will not only affect the appearance of the tire, but may also cause corrosion of the tire surface and shorten the service life of the tire.

[0035] The operator first places the scraper 5 into the first rectangular groove 4, aligning the locking hole 7 on the scraper 5 with the locking groove 6. Under the elastic force of the spring 10, the sliding block 9 moves downward along the sliding groove 8, causing the locking block 11 to insert into the locking hole 7 of the scraper 5, thus firmly fixing the scraper 5 in the first rectangular groove 4. If it is necessary to disassemble the scraper 5 for cleaning or replacement, simply loosen the screw 14, allowing the L-shaped block 13 to slide upward in the sliding through groove 12, causing the sliding block 9 and the locking block 11 to disengage from the locking hole 7 of the scraper 5, and the scraper 5 can be easily removed.

[0036] During the operation of the sweeper, the water pump 16 draws water from an external water source through the first connecting pipe 17, then pressurizes the water and delivers it to the high-pressure nozzle 19 through the second connecting pipe 18. The high-pressure nozzle 19 sprays water out in a high-pressure form to wash the wheels 3, effectively removing dust, mud and other dirt from the surface of the wheels 3, preventing dirt from being carried into the sweeper's interior or contaminating other areas.

[0037] By flexibly adjusting the position of the baffle 22 as needed, garbage can be effectively blocked from entering the sweeper's interior or other areas, protecting the sweeper's interior cleanliness and normal operation, reducing garbage on the wheel 3's path, and minimizing its impact on movement.
