Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically a grading and screening device for recycled aggregates. Background Technology

[0002] Recycling and reusing construction waste to produce recycled aggregates has significant environmental and economic implications. Recycled aggregates can be used to produce various building materials such as recycled concrete and road base materials, achieving resource recycling.

[0003] Traditional screening devices typically employ a single vibrating screening method. For recycled aggregates, which have a wide particle size distribution and irregular shape, the screening speed is slow and cannot meet the needs of large-scale production. Due to the complex composition of recycled aggregates, which contain particles of different sizes, traditional screening devices cannot accurately separate aggregates of different sizes, resulting in inconsistent quality of the screened aggregates. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a grading and screening device for recycled aggregates to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides a grading and screening device for recycled aggregate, including a fixed base, a stirring mechanism, a storage tank containing a stirring paddle, a discharge pipe extending from the lower end of the storage tank, and a drive motor coaxially connected to one end of the stirring paddle; a feeding mechanism attached to the outer wall of one side of the storage tank; a vibration mechanism fixedly connected to the lower end of the storage tank, the vibration mechanism including a support plate fixedly connected to the lower end of the discharge pipe, vibration motors mounted on both sides of the support plate, a base provided at the lower end of the support plate, and a shock-absorbing mechanism connecting the storage tank and the base; and an adjustment mechanism including multiple supports arranged at the front and rear ends of the base and extending downwards, the lower ends of the multiple supports being connected to the fixed base, and telescopic members connecting the lower ends of the rear ends of the base.

[0006] Preferably, the upper opening of the storage tank is hollow, and the bottom plate inside the storage tank cavity has a discharge port that is connected to the discharge pipe.

[0007] Preferably, one end of the discharge pipe is connected to the discharge port at the lower end of the storage tank, and the other end of the discharge pipe extends to the outside of the storage tank.

[0008] Preferably, there are two support plates, which are vertically fixed on both sides of the lower end face of the discharge pipe, and a vibration motor is installed on each fixed plate.

[0009] Preferably, the base has an open top and a hollow interior, and is positioned directly below the storage tank. A shock-absorbing mechanism is connected between the storage tank and the base.

[0010] Preferably, the shock absorption mechanism includes four shock absorption supports, which are arranged in a rectangular array and connected to the lower end face of the storage tank. The lower ends of the four shock absorption supports are connected to the base.

[0011] Preferably, the upper ends of the multiple supports are connected to both sides of the base, and the lower ends of the supports are axially connected to the middle of the fixed seat. A pneumatic telescopic component is connected to the lower end of the support at the rear end of the base for adjusting the tilt angle of the base. The beneficial effects of this invention are: by setting up a stirring mechanism, including a storage tank and a built-in stirring paddle, the recycled aggregate can be fully stirred, making the aggregate more uniform before entering the screening stage. This integrated stirring and screening design not only improves screening efficiency but also reduces the equipment footprint and production costs. It also avoids the problem of decreased screening accuracy due to uneven aggregate. The vibration mechanism, by installing a vibration motor on the support plate, can generate stable vibration, making the aggregate fully loosened during screening, thereby improving screening accuracy. The adjustment mechanism includes multiple supports, with pneumatic telescopic components connected to the lower ends of the supports, which can adjust the tilt angle of the base. By adjusting the tilt angle, the screening force and speed can be flexibly changed according to the particle size distribution of the recycled aggregate and screening requirements, thereby achieving precise screening of aggregates with different characteristics.
