AI Technical Summary
In the existing technology for screening soil and rock materials, the crushing of expansive soil requires manual knocking, which is inefficient and not conducive to automated screening and metering.
A soil crushing mechanism for a fully automatic intelligent screening and weighing device for soil and rock materials was designed, including a top plate and a striking rod. The top plate is driven by an electric cylinder or a pneumatic cylinder to drive the striking rod to automatically crush the expansive soil. Combined with the cooperation of the driving protrusion and the abutment rod, automated crushing is achieved.
It enables automated tapping of expansive soil, improves screening efficiency, and enhances the automation and convenience of soil and rock material screening and metering.

Abstract
Claims
1. A soil-crushing mechanism for a fully automatic intelligent screening and weighing device for soil and rock materials, characterized in that: Includes a receiving plate (10) and an ejector plate (20) disposed above the receiving plate (10). The bottom surface of the ejector plate (20) is provided with a plurality of striking rods (21). The receiving plate (10) is adapted to receive materials discharged from the discharge port (8) of the vibrating screen (4).
2. The full-automatic intelligent screening and weighing device for earthwork and aggregate according to claim 1, characterized in that: The ejector plate (20) is ejected by an electric cylinder or a pneumatic cylinder.
3. The full-automatic intelligent screening and weighing device for earthwork and aggregate, according to claim 1, characterized in that: A rubber block is provided at the bottom of the striking rod (21).
4. The soil crushing mechanism for the fully automatic intelligent screening and weighing device for soil and rock materials according to claim 1 or 3, characterized in that: The ejector plate (20) is connected to a second elastic element (22), and a drive rod (23) is provided on the side of the receiving plate (10). Several drive protrusions (24) are provided on the bottom surface of the drive rod (23) along the axial direction. An abutment rod (25) is provided on the top surface of the ejector plate (20); The receiving plate (10) is adapted to be able to move laterally, so that the ejector plate (20) moves closer to or further away from the drive rod (23), thereby causing the drive protrusions (24) to continuously abut against and push the abutment rod (25) to bounce.
5. The full-automatic intelligent screening and weighing device for earthwork and aggregate according to claim 4, characterized in that: The cross-section of some of the driving bumps (24) is wavy.
6. The full-automatic intelligent screening and weighing device for earthwork and aggregate according to claim 4, characterized in that: The receiving plate (10) is provided with a discharge hopper (34), and the top plate (20) is provided on the top of the discharge hopper (34).
7. The soil crushing mechanism for the fully automatic intelligent screening and weighing device for soil and rock materials according to claim 1, characterized in that: Several of the aforementioned striking rods (21) are arranged at equal intervals.
