AI Technical Summary
After drilling, the core sample of the existing highway inspection sampling machine tends to stick to the inside of the drill barrel, which requires operators to spend extra time and effort to remove it, thus affecting work efficiency.
The system employs a connecting plate, rack and pinion, and push plate structure, which enables automatic ejection of the core sample via gear transmission. It also incorporates a water tank and nozzle structure for cooling the drill barrel.
It enables automatic detachment of the core sample from the drill barrel, reducing the tediousness of manual operation, lowering labor intensity, and extending the service life of the equipment.
