Description

Technical Field

[0001] The present application relates to the technical field of aggregate production, and in particular to an aggregate transition bin. Background Art

[0002] Aggregate is a granular loose material that acts as a skeleton or filler in concrete. Aggregate is the main raw material in concrete and plays a skeleton and supporting role in buildings. Aggregates with a particle size greater than 4.75mm are called coarse aggregates, commonly known as stones, and the commonly used ones are crushed stone and pebbles; aggregates with a particle size of less than 4.75mm are called fine aggregates, commonly known as sand. Sand is divided into natural sand and artificial sand according to its source. In the production and processing of existing aggregates, coarse aggregates and fine aggregates are generally mixed together, which needs to be screened later, which is cumbersome to operate and has low production efficiency.

[0003] The existing patent (publication number: CN 211306915 U) discloses an aggregate transition bin with double discharge ports, which solves the problem that coarse aggregate and fine aggregate are generally mixed together during the production and processing of aggregates, and need to be screened in the later stage, which is cumbersome to operate and has low production efficiency. The patent comprises a mounting plate, a conical bucket and a screen drum, wherein a first discharge pipe is arranged at the bottom end of the conical bucket, and a bin body is arranged at the top end of the conical bucket, a screen drum is rotatably installed between the inner walls on both sides of the bin body, the screen drum is arranged obliquely, and a first pulley is fixed at one end of the screen drum, and a feed pipe is arranged at the end with a high inclination of the screen drum, and a second discharge pipe is arranged at the end with a low inclination of the screen drum, a motor is installed on the outer wall of the upper end of the bin body, a second pulley is concentrically fixed on the output shaft of the motor, and the second pulley is connected to the first pulley by winding through a V-belt, so as to facilitate the collection of aggregates of different particle sizes, reduce the amount of labor in the later stage, and improve production efficiency.

The upper surface of the bottom plate 1 is fixedly connected with four dampers 7, and the upper surface of each damper 7 is fixedly connected to the bottom surface of the side plate 6 respectively. The spring 5 and the damper 7 are used to buffer and reduce shock of the bin body 3, thereby increasing the stability of the bin body 3 during operation and optimizing the shock absorption effect of the aggregate transition bin.

[0033] See also Figure 3 The outer circumferential surface of the screen drum 8 is fixedly sleeved with a first limiting ring 9, and the outer circumferential surface of the first limiting ring 9 is rotatably connected to the interior of the bin body 3 to limit the screen drum 8, prevent the screen drum 8 from sliding and deviating, and increase the stability of the movement of the screen drum 8.

[0034] See also Figure 3 and Figure 4 The outer circumferential surface of the screen drum 8 is provided with equidistantly arranged screen holes 12, and the inner wall of the screen drum 8 is fixedly connected with equidistantly arranged stirring rods 13, through which the coarse aggregate and the fine aggregate are stirred to assist the fine aggregate to fall from the screen holes 12.

[0035] See also Figure 1 and Figure 3 A motor 14 is fixedly connected to the upper surface of the bin body 3, and the motor 14 is connected to a connecting belt 15 through an output shaft transmission. The other end of the connecting belt 15 is connected to the outer circumferential surface of the screen drum 8. The screen drum 8 is driven to rotate by the motor 14 and the connecting belt 15, so that the screen drum 8 can rotate, accelerate aggregate screening, and improve working efficiency.

[0036] See also Figure 3 The outer circumference of the rotating rod 16 is fixedly sleeved with a second limiting ring 19, and the outer circumference of the second limiting ring 19 is rotatably connected to the interior of the warehouse body 3 to limit the rotating rod 16, prevent the rotating rod 16 from sliding and deviating, and increase the stability of the movement of the rotating rod 16.

The second discharge port 23 is located at the end of the guide slope 22, so that the fallen fine aggregate can be discharged through the second discharge port 23 under the action of the guide slope 22, which is convenient for the classification and processing of coarse aggregate and fine aggregate.

[0039] In the aggregate transition bin of the present embodiment, the rotating rod 16 is driven to rotate in the opposite direction under the action of the driving gear 21 and the driven gear 20 during the rotation of the screen drum 8, so that the cleaning roller 17 drives the cleaning block 18 to penetrate into the screen hole 12.

[0040] It should be noted that the screen drum 8 is tilted downward at a certain angle, so that the coarse aggregate can automatically slide from the feed port 10 to the first discharge port 11 during the screening process.

[0041] The working principle of the above embodiment is:

[0042] When it is necessary to screen the aggregate, the starting motor 14 is used as power to drive the screen drum 8 to rotate through the output shaft and the connecting belt 15, and the aggregate is injected into the screen drum 8 through the feed port 10. With the rotation of the screen drum 8 and the stirring of the stirring rod 13, the fine aggregate will fall through the screen hole 12 to the guide slope 22, and then be discharged through the second discharge port 23. The coarse aggregate will gradually slide to the first discharge port 11 under the action of the downward inclination of the screen drum 8, and be discharged through the first discharge port 11. While the screen drum 8 rotates, it will drive the rotating rod 16 to rotate in the opposite direction through the driving gear 21 and the driven gear 20. The rotating rod 16 drives the cleaning block 18 to rotate in the opposite direction through the cleaning roller 17. The cleaning block 18 will penetrate into the screen hole 12 during the rotation to avoid blockage of the screen hole 12. The spring 5 and the damper 7 can buffer the vibration generated during the operation of the transition bin, thereby increasing the stability of the bin body 3.
