The water pressure is adjusted by the diversion valve 11, which is connected to the water spray assembly 4 by a hose. After adjusting the water pressure, the water is sprayed out from the water spray assembly 4.
[0017] exist Figure 5 and Figure 6In the middle, the mounting mechanism 8 includes an outer frame 801 mounted on the output end of the motor 7, and an insert 802 fixedly mounted on the upper surface of the brush plate 9 is slidably connected inside the outer frame 801.
[0018] This road maintenance vehicle with a convenient cleaning brush replacement has rounded corners at the end of the insert 802 to facilitate insertion of the insert 802 into the outer frame 801. The inner hole of the outer frame 801 and the cross-section of the insert 802 are both square to prevent the insert 802 from rotating inside the outer frame 801.
[0019] exist Figure 6 In the middle, both sides of the insert block 802 are provided with arc-shaped grooves 803 for engaging the plate 805. The plate 805 has a cross-shaped cross section, and the arc surface of the arc-shaped groove 803 is smaller than a semicircle. The outer frame 801 has a T-shaped opening 804 corresponding to the arc-shaped groove 803 for receiving the plate 805. The plate 805 is rotatably connected to the inner wall of the T-shaped opening 804 via a rotating shaft.

One end of the torsion spring is installed on the outer side of the plate 805, and the other end is installed on the inner wall of the T-shaped opening 804. When the insert block 802 is pulled down, the inner wall of the arc-shaped groove 803 pushes the plate 805 to rotate out of the T-shaped opening 804, as shown. Figure 7 As shown.
[0020] Specifically, in this road maintenance vehicle that facilitates the replacement of cleaning brushes, when the insert block 802 is pulled out, the inner wall of the arc groove 803 pushes the plate 805 to rotate and twists the torsion spring on the shaft of the plate 805. When the insert block 802 is pulled out from the outer frame 801, the torsion spring resets the plate 805 and retracts the plate 805 into the T-shaped opening 804.
[0021] exist Figure 6 In the middle, a limiting cylinder 806 for preventing plate 805 from rotating is slidably connected to the outer side of the outer frame 801. The limiting cylinder 806 abuts against plate 805 and blocks plate 805, preventing plate 805 from rotating, thereby allowing plate 805 to lock the insert block 802.
[0022] The road maintenance vehicle that facilitates the replacement of cleaning brushes can slide the limiting cylinder 806 upwards. After the plate 805 is moved away from one side, the plate 805 can rotate out of the T-shaped opening 804. Slide the limiting cylinder 806 downwards. After the plate 805 is blocked by the limiting cylinder 806, the plate 805 cannot rotate.
[0023] exist Figure 6 In the middle, a spring 807 is connected to the lower inner wall of the limiting cylinder 806 by screws. The other end of the spring 807 is connected to the outer wall of the outer frame 801 by screws.

[0024] This road maintenance vehicle facilitates the replacement of cleaning brushes. The limiting cylinder 806 protects the spring 807 to prevent impurities from affecting the extension and contraction of the spring 807. When the limiting cylinder 806 is slid upward, it will compress the spring 807. After the limiting cylinder 806 is released, the spring 807 will reset the limiting cylinder 806 and block the plate 805 again.
[0025] exist Figure 1 and Figure 3 In the filter mechanism 12, an outer casing 1201 is connected to the input end of the water pump 10 via a pipe. The outer casing 1201 is bolted to the carriage of the vehicle body 1. A sealing plate 1202 for sealing is also installed at the front of the outer casing 1201, and the front of the outer casing 1201 is connected to the water tank 3 via a pipe.
[0026] This road maintenance vehicle with a convenient cleaning brush replacement has a sealing plate 1202 with a sealing gasket that presses against the opening of the outer box 1201. The sealing plate 1202 is installed inside the outer box 1201 by bolts and hooks. After opening the sealing plate 1202, the impurities filtered out inside the outer box 1201 can be cleaned.
[0027] exist Figure 8 and Figure 9 In the middle, a partition 1203 for supporting the filter plate 1204 is installed on the inner wall of the outer casing 1201.
[0028] This road maintenance vehicle with a convenient cleaning brush replacement has a filter plate 1204 mounted on a partition 1203 with screws. The filter plate 1204 can be removed and replaced.

The water entering the outer box 1201 from the water tank 3 will wait for filtration on the input side of the partition 1203 and the filter plate 1204.
[0029] exist Figures 8-10 In the middle, a geared motor 1205 for driving the scraper 1206 to rotate is connected to one side of the outer casing 1201 via a motor mount. The scraper 1206 abuts against one side of the filter plate 1204 and is used to scrape off the impurities adsorbed on the surface of the filter plate 1204. Starting the geared motor 1205 can drive the scraper 1206 to rotate.
[0030] This road maintenance vehicle with a convenient cleaning brush replacement has a geared motor 1205 whose output end rotates through a sealed bearing on one side of the inner wall of the outer casing 1201. When the geared motor 1205 is started, it drives the scraper 1206 to rotate on the filter plate 1204, scraping off the impurities attached to the surface of the filter plate 1204 and preventing impurities from blocking the filter holes of the filter plate 1204 and affecting filtration.

The needle holder 1208 has pins that correspond one-to-one with the holes on the filter plate 1204. When the horizontal electric push rod 1207 is activated, it extends, causing the pins on the needle holder 1208 to insert into the holes of the filter plate 1204.
[0032] This road maintenance vehicle with a convenient brush replacement system features a sealed connection between the horizontal electric push rod 1207 and the outer casing 1201 for waterproofing. When the horizontal electric push rod 1207 is activated, it extends, inserting the pin of the needle holder 1208 into the filter hole of the filter plate 1204. This pushes out impurities from the filter hole and removes them with the scraper 1206. The two sets of filter plates 1204, the reduction motor 1205, the scraper 1206, the horizontal electric push rod 1207, and the needle holder 1208 work in turn to prevent water filtration failure when the pin of the needle holder 1208 is inserted into the filter hole of the filter plate 1204, thus affecting water spraying.
[0033] In summary: When using this road maintenance vehicle with a convenient brush replacement mechanism, firstly, open the cargo compartment of the vehicle body 1, fill the water tank 3 with water, then drive the vehicle body 1 on the road surface requiring maintenance. The engine 2 is started via the controller in the cab, driving the water pump 10 to operate.
