[0019] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a device for quickly picking stones required for stone concrete in accordance with the utility model in conjunction with the accompanying drawings.

[0020] like Figure 1 and Figure 2As shown, a fast picking device for flakes required for flake concrete comprises a first steel pipe column 4.1, a second steel pipe column 4.2 and a third steel pipe column 4.3 which are fixed on the ground symmetrically from front to back, the first steel pipe column 4.1 and the second steel pipe column 4.2 are respectively fixed with a cross-turn buckle 5 to the four corners of the first screen 1 and the second screen 2, the second steel pipe column 4.2 and the third steel pipe column 4.3 are fixed with a cross-turn buckle 5 to the four corners of the horizontally arranged third screen 3, the first screen 1 is located above the second screen 2, the second screen 2 is located above the third screen 3, the first screen 1 is inclined forward and downward, the second screen 2 is inclined backward and downward, so that the sides of the two form an eight-shaped shape, the second screen 2 and the third screen 3 have the same aperture, and are both smaller than the aperture of the first screen 1, and flakes of different sizes are loaded onto the first screen 1 by a loader 6.

[0021] In this embodiment, Figure 3 and Figure 4 As shown, the first screen 1, the second screen 2, and the third screen 3 are all square screens with a side length of 2.1 meters, and are welded with φ25 steel bars. The aperture of the first screen 1 is 30 cm, the aperture of the second screen 2 is 15 cm, and the aperture of the third screen 3 is 15 cm.

[0022] The first steel pipe column 4.1 and the second steel pipe column 4.2 are steel pipes with a diameter of 48 mm, a wall thickness of 3 mm and a length of 3 meters, and the third steel pipe column 4.3 is a steel pipe with a diameter of 48 mm, a wall thickness of 3 mm and a length of 1.5 meters.

[0023] like Figure 5 As shown, the cross-turn buckle 5 has two buckles, one side buckle fixes the steel pipe column, and the other side buckle fixes the screen.

[0024] The first steel pipe column 4.1, the second steel pipe column 4.2 and the first screen 1 and the second screen 2 are fixed with a cross-steering buckle 5 so that the two screens form a side eight-shaped screen with an angle of 60 degrees, which is convenient for filtering out stones of inappropriate size, and the lower side of the second screen 2 is 100 cm from the ground.

[0025] The third screen 3 is placed horizontally on the lower side of the second screen 2, 80 cm above the ground, and the third screen 3 is fixed to the second steel pipe column 4.2 and the third steel pipe column 4.3 by a cross-turn buckle 5, which can filter out some unsuitable-sized flakes for a second time, and finally leave flakes that meet the size requirements of the specification.

[0026] During operation, the loader 6 loads the flakes of different sizes onto the first screen 1. The flakes with a larger size than the first screen 1 will slide down to one side along the angle, and the flakes with a smaller size than the first screen 1 will fall onto the second screen 2. The flakes with a smaller size than the second screen 2 will fall below the second screen 2. The flakes that basically meet the requirements of the specification will fall onto the third screen 3 due to the angle between the second screen 2 and the horizontal plane. The third screen 3 can filter out some flakes of inappropriate size for a second time, and finally leave the flakes that meet the requirements of the specification. Finally, the flakes that meet the requirements of the specification are directly washed manually and put aside for use. It only takes a little time and labor to pick out a large number of flakes that meet the requirements of the specification.

[0027] The utility model can quickly and labor-savingly pick out stone pieces that meet the standard size, can improve work efficiency, is convenient for construction operation, reduces safety hazards, has a high recycling rate, and has low accessories prices, and has great promotion and application value.
