The material receiving pipe 11 is coaxially welded to the upper side of the material receiving barrel 12. Two adjacent barrel bodies are connected by a pair of buckles 24. A screening structure 25 is coaxially arranged between the two adjacent barrel bodies. The screening structure 25 comprises a screening frame 251, a screening net 252 and a rotating cylinder 256. The screening frame 251 is sealed and abutted between the upper and lower barrel bodies. The screening net 252 is installed by a pair of mounting holes. The shaft 254 is rotatably connected in the screening frame 251. A fixed plate 255 is provided at the rear of the screening frame 251, and the fixed plate 255 is vertically fixed on the screening frame. The rotating cylinder 256 is centrally installed on the fixed plate 255, and a rotating disk 257 is coaxially connected to its pneumatic component. The center of the rotating disk 257 is vertically connected to a rotating shaft 258, and the rotating shaft 258 is connected to a spline shaft 259 through a universal joint 261. The rear mounting shaft 254 is connected to a spline tube 260 through a universal joint 262, and the spline tube 260 and the spline shaft 259 are slidably fitted.

[0019] In this embodiment, a plurality of side mounting strips 17 are uniformly welded on the outer walls of the screening barrel 13, the screening barrel 2 14 and the screening barrel 3 15, and each side mounting strip 17 is connected to the screening frame through a compression spring 18. A pair of side mounting plates 19 are symmetrically welded on the outer walls of the screening barrel 13, the screening barrel 2 14 and the screening barrel 3 15, and a vibration motor 1 20 is installed on the side mounting plate 19. The vibration motor 1 20 can help screen the material on the screening net 252 in the screening material stage, and help clean the material on the screening net 252 in the material removal stage.

[0020] In this embodiment, the discharge barrel 16 is connected to the screening frame through a plurality of hook springs 21, a side mounting plate 22 is welded on the outer wall of the discharge barrel 16, and a vibration motor 23 is installed on the side mounting plate 22.

A weighing sensor is provided in the weighing bin, and the falling material is weighed and recorded by the weighing sensor.

[0023] The working principle of this automatic screening and detection device:

[0024] S1: First, the rotating cylinder 256 in all the screening structures 25 drives the corresponding screening nets 252 to flip to a horizontal state via the spline shaft 259, the spline tube 260, the universal joint 1 261 and the universal joint 2 262;

[0025] S2: The material taken out by the sampler is transported to the receiving barrel 12 through the discharge pipe and the receiving pipe 11, and then the material is layered on each layer of the powder screening net 252 through the high-frequency vibration of the vibration motor 20. After the screening is completed, the material exposed by the powder screening net 252 at the bottom directly falls into the weighing silo, and the falling material is weighed and recorded by the weighing sensor;

[0026] S3: From bottom to top, the rotating cylinder 256 in each screening structure 25 drives the corresponding screening net 252 to flip to a vertical state through the spline shaft 259, the spline tube 260, the universal joint 1 261 and the universal joint 2 262, and the materials on each layer of the powder screening net 252 fall into the weighing silo from bottom to top, and the falling materials are weighed and recorded by the weighing sensor, and then the difference calculation is performed based on the detected weight data, and the result is matched one by one with the corresponding particle size range, and the particle size ratio of the material is automatically calculated.

[0027] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
