Technical Field
[0001] This utility model relates to the field of crushing device technology, and in particular to a two-in-one sand making bucket. Background Technology
[0002] In the modern sand and gravel processing industry, sand making machines (also known as crushing machines) are one of the key pieces of equipment, used to crush large stones into fine particles that meet the needs of construction and industrial applications. Currently, the market mainly uses electric motor-driven fixed-point sand making methods, including four types: jaw crushers, impact crushers, movable hammer crushers, and stationary rotor hammer crushers.
[0003] Most existing sand making machines use a single crushing device, resulting in low crushing efficiency, especially for materials with high hardness. This limits output and fails to meet the needs of large-scale production, thus restricting production efficiency. Furthermore, since all materials pass through the same device, the load is high, equipment wear is severe, and the service life of the equipment is shortened.

An ear plate 4 is fixedly connected to the upper end of one side end face of the machine body 1. The ear plate 4 is used to connect with the excavator boom so that the two can cooperate stably and be used stably.
[0038] Working principle: When using this equipment, after assembling the ear plate 4 with the excavator arm, the excavator's inlet and outlet hydraulic oil pipes are connected to the inlet and outlet oil pipe interfaces of the sand making hopper, respectively. Then, when the excavator is started for normal operation, the hopper 5 contains material and the hook bucket is facing upwards. Step on the excavator's crushing pedal switch to enter the working state. At this time, the moving tooth plate 203 and the fixed tooth plate 204 of the first crushing device 2 perform jaw crushing action, initially crushing the stone to 10cm-15cm. The crushed stone is sent to the second crushing device 3. Driven by the core shaft 301, the hammers 305 connected in series on the through rod 304 rotate counterclockwise at high speed, crushing the stone. Finally, the crushed finished sand and gravel fall through the screen holes of the screen plate 6. Its coarseness is determined by the diameter of the screen holes of the screen plate 6, thereby achieving effective crushing of larger stones.
