Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0018] like Figure 1-7 As shown, a multi-stage screening device for all-coral concrete includes a screening mechanism 1, a cleaning mechanism 2, and a beating mechanism 3. The screening mechanism 1 includes a frame 11, a screening drum 12, and a discharge hopper 13. The frame 11 is horizontally arranged. The screening drum 12 is rotatably mounted on the frame 11 and includes a feeding section 121, a screening section 122, and a discharge section 123 connected sequentially from right to left. The discharge hopper 13 is located on the frame 11 and below the screening section 122. The beating mechanism 3 includes a fixing component 31, a beating component 32, a collision component 33, and a driving component 34. The beating component 32 is located on the rear side of the frame 11. The collision component 33 is connected to the beating component 32. The driving component 34 is drively connected to the beating component 32. The screening drum 12 rotates on the frame 11. When the coral raw material enters from the feed section 121 of the screening drum 12, it is screened through the screening section 122 to obtain coral particles of different sizes. During the screening process, the cleaning mechanism 2 cleans the screening drum 12, and the beating component 32 and the collision component 33 in the beating mechanism 3 beat and impact the screening drum 12 to prevent the screening section 122 from being blocked.

[0019] The screening section 122 includes a primary screening cylinder 1221 and a secondary screening cylinder 1223 connected sequentially from right to left. The primary screening cylinder 1221 is provided with primary sieve holes 1222; the secondary screening cylinder 1223 is provided with secondary sieve holes 1224, and the aperture of the secondary sieve holes 1224 is larger than that of the primary sieve holes 1222. After the coral raw material enters the screening section 122, it first enters the primary screening cylinder 1221. Coral raw material with an aperture smaller than that of the primary sieve holes 1222 is discharged. Coral raw material with an aperture larger than that of the primary sieve holes 1222 continues to enter the secondary screening cylinder 1223. Coral raw material with an aperture smaller than that of the secondary sieve holes 1224 is discharged. Coral raw material with an aperture larger than that of the secondary sieve holes 1224 enters the discharge section 123 and is discharged, thereby obtaining coral particles of three different sizes.

[0020] In a further embodiment, more screening cylinders with different aperture sizes can be set according to screening requirements, thereby obtaining more coral particles of different sizes to meet actual screening needs.

[0021] Two feeding hoppers 13 are provided, respectively located below the primary screening cylinder 1221 and the secondary screening cylinder 1223. The two feeding hoppers 13 respectively feed coral particles that have passed through the primary sieve holes 1222 and the secondary sieve holes 1224, facilitating collection and classification.

[0022] The cleaning mechanism 2 includes a mounting plate 21, a mounting platform 22, a mounting bearing seat 23, a cleaning shaft 24, a cleaning roller 25, and a cleaning brush 26. The mounting plate 21 is located on the front side of the frame 11 along the left-right direction. Two mounting platforms 22 are provided, vertically positioned on the left and right sides of the top surface of the mounting plate 21, respectively. The mounting bearing seats 23 are respectively located on the top surfaces of the two mounting platforms 22. The cleaning shaft 24 is arranged along the left-right direction, with its two ends connected to the two mounting bearing seats 23. The cleaning roller 25 is fixedly sleeved on the cleaning shaft 24. The cleaning brush 26 is located on the cleaning roller 25 and can contact the screening section 122. When the screening drum 12 rotates, it can contact the cleaning brush 26, which cleans the screen holes to prevent clogging. At the same time, the rotation of the screening drum 12 drives the cleaning brush 26 to rotate, improving the cleaning effect.

[0023] The fixing assembly 31 includes a fixing plate 311, a fixing frame 32, a fixing platform 33, a fixing bearing seat 34, a tapping shaft 35, and a tapping roller 36. The fixing plate 311 is located on the rear side of the frame 11 along the left-right direction. Two fixing frames 32 are provided, respectively vertically located on the left and right sides of the top surface of the fixing plate 311. The fixing platforms 33 are respectively located on the top surfaces of the two fixing frames 32. The fixing bearing seats 34 are respectively located on the top surfaces of the fixing platforms 33. The tapping shaft 35 is arranged along the left-right direction, and its left and right sides are connected to the two fixing bearing seats 34. The tapping roller 36 is fixedly sleeved on the tapping shaft 35. The tapping assembly 32 is located on the tapping roller 36. The driving assembly 34 drives the tapping shaft 35 to rotate, which in turn drives the tapping roller 36 to rotate, thereby driving the tapping assembly 32 to tap on the screening section 122, knocking off the coral raw material stuck or stuck in the screen holes, and further preventing the screen holes from clogging.

[0024] Multiple striking components 32 are provided, staggered on the front and rear side walls of the striking roller 36, and include a connecting plate 321 and a striking belt 322. One end of the connecting plate 321 is fixedly connected to the side wall of the striking roller 36, and the other end is connected to the striking belt 322. The free end of the striking belt 322 can contact the screening section 122. When the striking roller 36 rotates, it drives the striking belt 322 to rotate, and the free end of the striking belt 322 strikes the screening section 122.

[0025] The collision component 33 includes a connecting rope 331 and a collision ball 332; one end of the connecting rope 331 is fixedly connected to the free end of the beating belt 322, and the other end is fixedly connected to the collision ball 332. When the beating belt 322 beats on the screening section 122, the collision ball 332 can also impact the screening section 122, increasing the beating force and improving the knocking effect on the coral raw material.

[0026] The collision ball 332 is provided with a semi-circular protrusion 3321. When the collision ball 332 impacts the screening section 122, the semi-circular protrusion 3321 on the collision ball 332 can enter the screen hole and impact the coral material stuck on the screen hole, further improving the knocking effect on the coral material.

[0027] In a further embodiment, the impact ball 332 is made of rubber material, which ensures the knocking effect while preventing damage to the roller.

[0028] Each of the aforementioned slapping belts 322 is equipped with multiple collision components 33. The multiple collision components 33 can ensure the anti-clogging effect.

[0029] The drive assembly 34 includes a tapping motor 341, a drive sprocket 342, a driven sprocket 343, and a chain 344. The tapping motor 341 is located in the middle of the left-side fixed frame 32, with its output shaft facing left. The drive sprocket 342 is fixedly sleeved on the output shaft of the tapping motor 341. The driven sprocket 343 is fixedly sleeved on the left end of the tapping shaft 35 and is connected to the drive sprocket 342 via the chain 344. When the output shaft of the tapping motor 341 rotates, it drives the drive sprocket 342 to rotate, which in turn drives the driven sprocket 343 to rotate via the chain 344. The driven sprocket 343 then drives the tapping shaft 35 to rotate, thus achieving the tapping action.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
