Description

Technical Field

[0001] This utility model relates to the field of concrete aggregate screening technology, specifically a concrete aggregate screening device. Background Technology

[0002] Concrete is used extensively in road construction, and stone is an important building material. Commonly used stones in engineering include granite, gneiss, diorite, sandstone, and limestone. Generally, natural rocks must undergo certain processing to meet the requirements of engineering projects.

[0003] Currently, existing concrete aggregate screening devices typically screen aggregates to a suitable size. During use, as the concrete aggregates are screened through a screen plate, some aggregates accumulate on the plate, causing some to be blocked and unable to be screened. This results in incomplete screening and a problem of insufficient aggregate screening. Furthermore, dust is present inside the aggregates during use. When screening, this dust floats and surrounds the device, potentially affecting workers. There is also a problem with the inability to control this dust. Utility Model Content

A toothed disc 6 is connected to the side of the first gear groove 4, and a transmission gear 8 is connected to one side of the first gear groove 4. One side of the connecting plate 7 contacts the drum screen 5. A movable door 3 is provided at the lower end of the main body 1. The movable door 3 is located on one side of the slope 2. A fixed plate 18 is connected to one side of the connecting plate 7 by a bearing. A toothed disc 6 is fixedly connected to one side of the fixed plate 18. A connecting plate 7 is connected to one side of the toothed disc 6 by a bearing. The fixed plate 18 fits closely with the inside of the drum screen 5. A stirring rod 17 is fixedly connected to one side of the fixed plate 18. The stirring rod 17 is arranged in a ring array. There is a gap between the stirring rod 17 and the protrusion 20. Stones are added to the drum screen 5 by setting the feed hopper 13. The drum screen 5 is driven to rotate by setting the output motor 22, output gear 23, movable ring 21, and second gear groove 12. The protrusion 20 is set to facilitate the stirring of the stones.

[0028] In use, the stones are poured into the feed hopper 13, and the baffle 14 is pressed downwards to enter the drum screen 5. The output motor 22 is started, which drives the output gear 23 to rotate. Through the second gear groove 12 that meshes with it, the movable ring 21 is driven to rotate, thereby causing the drum screen 5 connected to it to rotate and screen the stones. The inner side of the drum screen 5 is provided with protrusions 20 to facilitate the movement of the stones. When the drum screen 5 rotates, the first gear groove 4 drives the transmission gear 8 to rotate, thereby driving the gear disc 6 to rotate.

Through cooperation with the protrusions 20, the stones are facilitated to move in the drum screen 5 for easy screening. After screening, the stones fall onto the slope 2. The movable door 3 is opened to remove the screened stones. Then the connecting plate 7 is removed, thereby driving the stirring rod 17 to be removed, thus removing the stones from the drum screen 5, achieving the purpose of fully screening the stones.

[0029] Example 2

[0030] Please see Figures 1 to 6 This utility model provides a technical solution: a concrete aggregate screening device, including a main body 1, a feeding hopper 13 fixedly connected to one side of the main body 1, a baffle 14 connected to the internal bearing of the feeding hopper 13, a support spring 15 fixedly connected to the lower end of the baffle 14, one end of the support spring 15 fixedly connected to the feeding hopper 13, a movable ring 21 connected to the internal bearing of the main body 1, a drum screen 5 fixedly connected to one side of the movable ring 21, a bearing connecting the main body 1 to one side of the drum screen 5, a ramp 2 provided at the lower end of the main body 1, an air pump 26 fixedly connected to one side of the main body 1, a connecting box 25 fixedly connected to the upper end of the air pump 26, a main body 1 fixedly connected to one side of the connecting box 25, a support plate 24 provided on one side of the connecting box 25, a support frame 28 fixedly connected to one side of the support plate 24, the upper end of the support frame 28 contacting a filter bag 16, and the upper part of the filter bag 16...

The lower end of the main body 1 has a suction port 19, which is located at the upper end of the drum screen 5. The upper end of the suction port 19 is connected to the conveying trough 10. By setting the baffle 14 and the support spring 15, the feed hopper 13 is blocked to prevent dust from drifting out. By setting the suction port 19, the conveying trough 10, the transmission pipe 9, and the connecting pipe 11, the dust is sucked and conveyed. By setting the filter bag 16, the dust is filtered and collected. By setting the support frame 28 and the fixed frame 27, the filter bag 16 is supported.

[0031] In use, the stone is poured into the feed hopper 13, and the baffle 14 is pressed down. The support spring 15 supports the baffle 14, thus blocking the feed hopper 13 and preventing the floating dust during screening from drifting out of the feed hopper 13. The dust floats in the main body 1. The air pump 26 is started, and the dust is sucked into the conveying trough 10 through the suction port 19. Then, it is concentrated into the connecting pipe 11 through the connected transmission pipe 9 and discharged into the connecting box 25. The dust is filtered through the filter bag 16 and stored in the filter bag 16. When there is a lot of dust in the filter bag 16, the support plate 24 is removed, which drives the support frame 28 to separate from the connecting box 25. The fixing frame 27 is separated from the support frame 28, so the filter bag 16 can be taken out and cleaned, thus achieving the purpose of dust treatment.
