Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vibrating screen, in particular to a screening machine with recyclable materials. BACKGROUND

[0002] Concrete aggregate refers to the granular material that plays a role in the skeleton or filling in concrete. According to the particle size, concrete aggregate can be divided into coarse aggregate and fine aggregate. Coarse aggregate mainly includes pebbles and crushed stones, and fine aggregate mainly includes natural sand and artificial sand. As a filling material of concrete, aggregate can occupy the voids in concrete, thereby improving the density and strength of concrete.

[0003] With the construction of cities, a large amount of waste concrete will be generated. After crushing, screening and subsequent processing, the waste concrete can generate recyclable recycled concrete aggregate, which can be used to replace part or all of the natural aggregate. Although the recycled concrete aggregate is slightly lower than the natural concrete aggregate in terms of compressive strength and durability, its performance can be significantly improved by optimizing the aggregate gradation and controlling the aggregate quality. In the production and processing of recycled concrete aggregate, a screening machine is usually used to screen out stone blocks and sand of different particle sizes as needed.

[0004] A recycled concrete aggregate screening device is disclosed in Chinese Patent No. CN220941710U, which includes a screening box. The left and right inner walls of the screening box are provided with a screening mechanism for multi-stage screening of concrete aggregate. An auxiliary mechanism is provided on the left side of the screening box to assist in improving the efficiency of aggregate screening. The screening mechanism includes three fixed plates fixed on the left and right inner walls of the screening box. The upper surfaces of the fixed plates on the left and right sides are fixed with vibration springs, and the upper surfaces of the vibration springs on the left and right sides are fixed with sieve plates. The front and rear sides of the three sieve plates are fixed with connecting frames. A support frame is fixed on the left inner wall of the screening box. The upper surface of the support frame is fixed with a drive motor. The outer side of the output shaft of the drive motor is fixed with a turntable. The front surfaces of the turntable and the connecting frame are fixed with connecting rods, and the outer surfaces of the two connecting rods are rotatably connected with swing arms.

[0005] In use, the drive motor is started, the turntable is driven to rotate through the motor output shaft, the swing arm is driven to rotate in an elliptical path through the connecting rod, and the connecting frame is driven to swing up and down. The three sieve plates are fixed between the connecting frame and the three sieve plates, so that the three sieve plates can be vibrated and screened simultaneously when the connecting frame swings. Finally, the micro-particle aggregate screened out will fall and be sent out by the discharge conveyor belt.

[0006] In the above technology, the aggregate is screened during the movement from the head end to the tail end of the screen plate, the aggregate near the tail end of the upper screen plate will fall to the position near the tail end of the lower screen plate and be directly conveyed out along the lower screen plate, and this part of the aggregate is discharged from the screening device without being fully screened, resulting in insufficient screening of the aggregate. SUMMARY

[0045] The implementation principle of the material recyclable screening machine is as follows: when the material needs to be screened, first, the vibrating motor 3 is started, the vibrating motor 3 drives the vibrating frame 2 to vibrate, the material is added from the front end of the vibrating frame 2 to the screen one 4, the material slides along the screen one 4 and is screened through the screen one 4, part of the material slides along the screen one 4 and then falls into the conveying belt to be conveyed out, part of the material passes through the screen one 4 and then slides along the second baffle 73 to the front end of the screen two, the second baffle 73 can buffer the material, after the material passes through the second baffle 73, the material falls to the screen two to be screened;

[0046] When the aggregate on the screen one 4 is more, the driving part two 91 is started, the gear two 93 is driven to rotate, the driving rod two 92 is driven to slide along the length direction of the driving rod two 92, when the driving rod two 92 slides, the plurality of gear two 93 are simultaneously driven to rotate, the gear two 93 drives the rotating shaft two 71 to rotate, the rotating shaft two 71 drives the first baffle 72 and the second baffle 73 to rotate, when the second baffle 73 abuts against the rotating shaft two 71 on the adjacent guide plate 7, the storage chamber for storing the material is formed (the state is as shown in Figure 3As shown in the figure, the material falling through the screen 4 can be stored in the storage chamber; meanwhile, during the rotation of the rotating shaft 2 71, the rotating shaft 2 71 drives the first baffle 72 to rotate, the first baffle 72 drives the scraper 10 to rotate, the top end of the scraper 10 moves along the screen 4, and the scraper 10 can push the large-particle material stuck in the screen 4 to prevent the screen 4 from being blocked;

[0051] Through the arrangement of the guide plates 7 and the driving mechanism two, in the initial state, the second baffle 73 is arranged to be inclined along the vertical downward direction to the front end of the vibrating frame 2, after the materials fall from the screen one 4 to the screen two, the materials slide along the second baffle 73 and slide to the front end of the screen two, and fall on the screen two for screening, so that the materials can be prevented from falling to the position close to the end of the screen two and being directly conveyed out along the screen two, thereby making the screening of the materials more sufficient, and the second baffle 73 can also have a buffering effect, preventing the materials from directly hitting the screen two and affecting the service life of the screen two, and through the rotation of the rotating shaft two 71 and the second baffle 73 driven by the driving mechanism two, the second baffle 73 abuts against the rotating shaft two 71 on the adjacent guide plate 7 to form a storage chamber for storing materials, when the materials on the screen one 4 are more, the storage chamber is used to store the materials, thereby preventing the materials from entering the screen two and causing the screening of the materials on the screen two to be insufficient.

[0052] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
