[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: a dust removal maintenance device for a concrete mixing station, comprising a shell 1, a cavity is arranged inside the shell 1, a collecting port 2 is fixedly connected to the top of the front side of the shell 1, three transmission rollers 3 are rotatably connected to the inner wall of the cavity, and the outer walls of the three transmission rollers 3 are sleeved with an adhesive belt 4, a driving end of a motor 10 installed at the rear end of the right side of the shell 1 is fixedly connected to the right side of another transmission roller 3, a water pool 5 is arranged in the middle of the bottom end of the cavity, the bottom transmission roller 3 is located inside the water pool 5, the bottom end of the adhesive belt 4 is located inside the water pool 5, the top front side of the adhesive belt 4 is located at the rear side of the collecting port 2, a cylinder 6 is fixedly connected to the top side of the shell 1, the bottom side of the cylinder 6 is located at the front end of the top side of the adhesive belt 4, a fan blade 8 is rotatably connected to the right side of the cylinder 6, and two pulleys 9 located on the right side of the shell 1 are connected by a belt, one of the pulleys 9 is fixedly connected to the right side of the fan blade 8, and the other pulley 9 is fixedly connected to the right side of one of the adhesive belts 4;

[0026] Specifically, the collecting port 2 is connected to a collecting head for collecting dust to expand the dust collection range of the concrete mixing station. The inner side of the adhesive belt 4 has a certain friction force, so that it is easy to be driven by the driving roller 3. The other side of the adhesive belt 4 is relatively smooth. When the driving roller 3 drives the adhesive belt 4 to move, the right side is the main viewing angle. The adhesive belt 4 moves in a counterclockwise direction. After passing through the pool 5, the surface of the adhesive belt 4 will be stained with water and is in a wet state that is easy to be stained with dust. Driven by the motor 10, the other transmission roller 3 rotates, thereby driving the adhesive belt 4 to move, and driving one of the transmission rollers 3 to rotate, so that the pulley 9 connected to it rotates, and the pulley 9 connected to the fan blade 8 is rotated by belt transmission, so that the fan blade 8 rotates, generating attraction in the cylinder 6, thereby generating suction on the collecting port 2 to collect dust. When the adhesive belt 4 passes through the collecting port 2, the dust entering from the collecting port 2 will adhere to the surface of the wet adhesive belt 4 to form a wet dust deposit, and move with the adhesive belt 4. Since the dust is in a wet accumulation state, it is not easy to scatter to the inside of the equipment, thereby avoiding the rest of the equipment from being affected by the dust, ensuring the normal operation of the equipment, reducing the maintenance of the equipment, and thus reducing manpower consumption.

[0027] Reference Figure 3 and Figure 4 The top of the scraper 12 installed at the rear side of the pool 5 abuts against the rear periphery of the adhesive tape 4, and a collecting box 13 is provided at the bottom end of the scraper 12. The collecting box 13 is installed at the rear of the bottom end of the cavity through a slide rail;

[0028] Specifically, when the adhesive tape 4 moves to the rear end of the cavity, the surface of the adhesive tape 4 will be scraped by the scraper 12, so that the moist dust deposits adhering to the surface of the adhesive tape 4 are scraped off, and the deposits fall into the interior of the collecting box 13 on the bottom side and are collected. The collecting box 13 can be pulled out by sliding on a slide rail, so that the dust deposits in the collecting box 13 can be cleaned and recovered.

[0029] Reference Figure 3 and Figure 5 , a filter plate 7 is arranged inside the chute on the left side of the cylinder 6, and both sides thereof are fixedly connected with slides 11, and the filter plate 7 is slidably connected inside the chute through the slides 11;

[0030] Specifically, since the cylinder 6 that generates attraction is located near the collecting port 2, the dust cannot be completely attached to the surface of the adhesive belt 4. In order to ensure that dust is not excessively accumulated on the surface of the fan blade 8, the filter plate 7 arranged in the cylinder 6 can block the dust to a certain extent. The filter plate 7 connected with the slide 11 can be taken out of the slide groove by pulling, so that its surface can be cleaned or replaced.

[0031] Reference Figure 2 A water inlet pipe for filling clean water into the water pool 5 and a water outlet pipe for discharging waste water are installed on the left side of the water pool 5, and a valve for controlling drainage is installed on the outer wall of the water outlet pipe.

[0032] Working principle: When collecting dust for dust removal work in a concrete mixing station, another driving roller 3 is driven by a motor 10 to rotate, thereby driving the adhesive belt 4 to move, and driving one of the driving rollers 3 to rotate, thereby rotating the pulley 9 connected to it, and using the belt drive to rotate the pulley 9 connected to the fan blade 8, so that the fan blade 8 rotates, generating attraction in the cylinder 6, thereby generating suction on the collection port 2 to collect dust. When the adhesive belt 4 passes through the collection port 2, the dust entering from the collection port 2 will adhere to the surface of the wet adhesive belt 4 to form a wet dust accumulation, and move with the adhesive belt 4. When the adhesive belt 4 moves to the rear end of the cavity, the surface of the adhesive belt 4 will be scraped by the scraper 12, so that the wet dust accumulation adhering to the surface of the adhesive belt 4 is scraped off, and the accumulation falls into the inside of the collection box 13 on the bottom side to collect it. The collection box 13 can be pulled out by sliding on a slide rail, so that the dust accumulation in the collection box 13 can be cleaned and recovered.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
