Two sets of inverted F-shaped supports 1 are correspondingly arranged. The side end of the inverted F-shaped support 1 can be used as a push handle, and the bottom end of the inverted F-shaped support 1 is correspondingly equipped with braked casters 16, facilitating the operator's gripping and movement of the entire machined sand and gravel powder screening device, improving the device's mobility between different work locations. The U-shaped support plate 2 is horizontally arranged on the inverted F-shaped support 1. A rotating shaft 4 is correspondingly installed on the support 1. The screening box 3 is connected to the inverted F-shaped support 1 through the rotating shaft 4. The screening box 3 is equipped with a screen plate 5. The screening box 3 is designed with an inclination. A zigzag-shaped opening 6 is opened at the bottom of the inclination to facilitate the installation and disassembly of the screen plate 5. A stone powder collection trough 14 is provided on the lower side of the opening 6 to facilitate the collection of the screened stone powder for subsequent centralized processing. A discharge hopper 15 is installed on the top of the screening box 3 away from the opening 6 for easy discharge. A vibration mechanism 7 is installed on the screening box 3.
[0023] The vibration mechanism 7 includes a vibration motor 8, support blocks 9, and springs 10. The vibration motor 8 is installed at the bottom of the screening box 3. Four sets of support blocks 9 are arranged in pairs on both sides of the screening box 3. To ensure the stability of the screening box 3 during vibration, one end of the spring 10 is fixed to the lower part of the support block 9, and the other end of the spring 10 is fixed to the top of the U-shaped support plate 2. The high-frequency vibration energy generated by the vibration motor 8 will drive the screening box 3 to vibrate and screen the manufactured sand and gravel powder material inside the box. The spring 10 will stretch and deform under the action of vibration force. Its elastic characteristics will convert and buffer the vibration force into regular elastic vibration, thereby driving the screening box 3 to vibrate up and down. At the same time, when the screening box 3 shifts to one side, the stretching or compression of the corresponding side spring 10 will be compensated by the other side spring 10 to avoid it from falling out of place due to excessive vibration force, thus ensuring stable and reliable screening operation.
