[0002] Premixed concrete refers to a concrete mixture that is prepared by mixing cement, aggregates, water, and, if necessary, admixtures, mineral admixtures, etc. in a certain proportion, metered and mixed at a mixing station, and then sold and transported to the use location by a transport vehicle within a specified time.

[0003] In the prior art, the cement silo for premixed concrete processing is mainly used for storing and transporting cement.

Especially in a dry environment, it is easy to generate dust. If appropriate dust suction treatment is not taken, these cement dusts will drift everywhere with the flow of air, which will not only pollute the surrounding environment and affect air quality, but also pose a threat to the health of workers.

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 4As shown in the figure, the utility model provides a dust-proof and dust-suppressing cement silo for premixed concrete processing, which includes a plurality of support columns 1. A rotary dust suction mechanism 2 is fixedly connected to the tops of the plurality of support columns 1, and a blanking mechanism 3 is fixedly connected to the bottoms of the plurality of support columns 1. The rotary dust suction mechanism 2 includes a fixed plate 201. A U-shaped plate 202 is fixedly connected to the bottom of the fixed plate 201. A driving motor 203 is arranged on the top of the U-shaped plate 202. The output end of the driving motor 203 slidably penetrates through the top of the U-shaped plate 202 and extends downward. The output end of the driving motor 203 is fixedly connected to a first rotating rod 204. A first tooth sleeve 205 is arranged on the outer surface of the first rotating rod 204. The outer surface of the first tooth sleeve 205 is meshed with a second tooth sleeve 206. A second rotating rod 207 is arranged on the inner wall of the second tooth sleeve 206. The bottom of the fixed plate 201 is fixedly connected to the top of the support column 1. The bottom of the second rotating rod 207 is fixedly connected to a rotating disc 208. Two connecting plates 209 are symmetrically and fixedly connected to the bottom of the rotating disc 208. A plurality of air suction heads 210 are fixedly connected to the opposite sides of the two connecting plates 209. A suction pump 211 is fixedly installed on the top of the fixed plate 201. An air distribution pipe 212 is arranged on the outer surface of the suction pump 211. One end of the air distribution pipe 212 is fixedly communicated with a collection box 213. The suction pump 211 is communicated with the plurality of air suction heads 210.

[0023] The effect achieved by the entire embodiment 1 is that during use, first start the driving motor 203 on the U-shaped plate 202, and drive the first rotating rod 204 to rotate with its output end. During the rotation of the first rotating rod 204, the first tooth sleeve 205 can be driven to rotate. Due to the meshing connection between the first tooth sleeve 205 and the second tooth sleeve 206, the second tooth sleeve 206 can be driven to rotate during the rotation of the first tooth sleeve 205. And since the diameter of the first tooth sleeve 205 is smaller than that of the second tooth sleeve 206, a speed reduction effect can be achieved during the rotation of the second tooth sleeve 206. During the rotation of the second tooth sleeve 206, the second rotating rod 207 and the rotating disc 208 can be driven to rotate, so that the two connecting plates 209 and the plurality of air suction heads 210 rotate around the cement silo 305. At this time, start the suction pump 211 on the fixed plate 201. Under the action of the suction pump 211, the air suction heads 210 will suck the dust generated during the blanking process into the air distribution pipe 212 and finally transport it to the collection box 213. Under the action of the rotary dust suction mechanism 2, dust can be sucked during the blanking process of premixed concrete, thereby preventing these cement dusts from floating around with the air flow, reducing the impact of cement dust on air quality, and protecting the health of the staff. The support column 1 is mainly used to connect the fixed plate 201.

[0024] Embodiment 2, as Figures 1 - 4As shown, the blanking mechanism 3 includes a bottom plate 301. Two sliding grooves 302 are symmetrically formed at the top of the bottom plate 301. The inner walls of the two sliding grooves 302 are both slidably connected with sliding plates 303. The front surfaces of the two sliding plates 303 are fixedly connected with handles 304. A cement tank 305 is fixedly installed on the inner walls of the two sliding plates 303. A threaded cover 306 is threadedly connected to the position near the lower part of the outer part of the cement tank 305. The top of the bottom plate 301 is fixedly connected to the bottom of the support column 1.

[0025] The overall effect achieved by the entire Embodiment 2 is that during use, first place the cement tank 305 within the two sliding plates 303. At this time, by pushing the handle 304, the sliding plate 303 is driven to move within the sliding groove 302, moving the cement tank 305 between the connecting plates 209. Subsequently, place the blanking tool for the ready-mixed concrete on the bottom plate 301 so that it can receive the cement released from the cement tank 305. Then, open the threaded cover 306 to start the blanking work. Under the action of the blanking mechanism 3, it is convenient for the staff to use. Just pull or push the handle 304 to carry out the taking or blanking work, improving the convenience for the staff during use.

[0026] Working principle: During use, by pushing the handle 304, the sliding plate 303 is driven to move within the sliding groove 302, moving the cement tank 305 between the connecting plates 209. Subsequently, place the blanking tool for the ready-mixed concrete on the bottom plate 301 so that it can receive the cement released from the cement tank 305. Then, open the threaded cover 306 to start the blanking work. Subsequently, start the driving motor 203 to drive the first rotating rod 204 to rotate. During the rotation of the first rotating rod 204, the first gear sleeve 205 can be driven to rotate. During the rotation of the first gear sleeve 205, the second gear sleeve 206 can be driven to rotate. Since the diameter of the first gear sleeve 205 is smaller than that of the second gear sleeve 206, a speed reduction effect is achieved during the rotation of the second gear sleeve 206. During the rotation of the second gear sleeve 206, the second rotating rod 207 and the rotating disc 208 can be driven to rotate, causing the multiple air suction heads 210 of the two connecting plates 209 to rotate around the cement tank 305. At this time, start the suction pump 211. Under the action of the suction pump 211, the air suction heads 210 will suck the dust generated during the blanking process into the air distribution pipe 212 and finally transport it to the collection box 213.

[0027] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the protection scope of the technical solution of the present utility model.
