Embodiment

[0031] With reference to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the second embodiment of the utility model is based on the previous embodiment, and the cleaning mechanism 3 comprises a scraper 305 slidably connected to the inner wall of the fixed frame 202. The outer surface of the scraper 305 is threadedly connected with a threaded rod 304, and both ends of the threaded rod 304 are rotatably connected to the inner wall of the fixed frame 202.

[0032] The specific cleaning mechanism 3 further comprises a motor 303 fixedly connected to the outer surface of the fixed frame 202. The output shaft of the motor 303 is fixedly connected with one end of the threaded rod 304. The outer surface of the fixed frame 202 is fixedly connected with a control panel 4. The end of the fixed frame 202 away from the motor 303 is fixedly connected with a limiting track 307. The inner wall of the limiting track 307 is slidably connected with a baffle 306. The outer surface of the baffle 306 is fixedly connected with a connecting block 302. The outer surface of the fixed frame 202 is fixedly connected with an electric telescopic rod 301. The output end of the electric telescopic rod 301 is fixedly connected with the outer surface of the connecting block 302.

[0033] Further, through the linkage of the motor 303 and the electric telescopic rod 301, the scraper 305 and the baffle 306 can automatically clean the residues in the filter screen 203 and the fixed frame 202, reduce manual intervention, improve the cleaning efficiency, and prolong the service life of the equipment.

[0034] Working principle: first start the fixed frame 202 inner wall of the suction fan 207. Suction fan 207 starts to run, quickly remove the gas in the fixed frame 202, so that the fixed frame 202 form a negative pressure environment. Under the action of negative pressure, through the connecting pipe 204 and fixed pipe 206, the suction port of the first suction frame 201 and the second suction frame 205 also produce negative pressure, the first suction frame 201 close to the inlet 5, can effectively capture in the process of adding concrete additives scattered to the air in the additives; the second suction frame 205 is located in the outer surface of the discharge port 6, can timely suck up the concrete additives raised in the discharge port 6 in the discharge. These concrete additives and dust sucked into the fixed frame 202, the filter screen 203 arranged in the inner wall of the fixed frame 202 can filter the mixed gas into the concrete additives intercepted on the surface of the filter screen 203, prevent it from entering the inside of the suction fan 207, avoid damage to the suction fan 207, also realize the recycling of concrete additives, reduce the waste of materials, and the filtered air will be discharged from the equipment under the action of the suction fan 207, effectively reduce the dust pollution to the environment in the mixing operation process.

[0035] With the continuous progress of the mixing operation, a large amount of concrete additives will gradually accumulate on the filter screen 203, affecting the filtering effect and the normal operation of the equipment. At this time, the operator starts the motor 303 through the control panel 4. The output shaft of the motor 303 starts to rotate, driving the threaded rod 304 connected therewith to rotate synchronously. Since the scraper 305 is threadedly connected with the threaded rod 304, when the threaded rod 304 rotates, the scraper 305 will slide along the inner wall of the fixed frame 202. The lower surface of the scraper 305 is in close contact with the upper surface of the filter screen 203 and generates friction during the sliding process, so as to gradually push the concrete additives blocked on the upper surface of the filter screen 203 to the position where the baffle 306 is located. At the same time, the operator starts the electric telescopic rod 301. The output end of the electric telescopic rod 301 starts to act, driving the connecting block 302 and the baffle 306 fixedly connected therewith to move up and down on the inner wall of the limiting rail 307. The up and down movement of the baffle 306 can further concentrate the concrete additives pushed by the scraper 305, facilitating subsequent cleaning.
