The gap with the preset width can be set according to actual needs, and this embodiment does not limit this.
The following details the structure and operation principle of each part of the sieving and crushing bucket:
in one possible design, the power unit 2 includes: two hydraulic motors 21, and two of the hydraulic motors 21 are communicated with each other through a balance valve.
The hydraulic motor 21 is a hydraulically driven engine, and its operating principle is: for converting hydraulic energy into mechanical energy and outputting it, thereby powering each screening unit 3. The balance valve is a valve with special function, which is used to adjust the relative balance of the pressures on both sides, or achieve the flow balance by a shunting method, thereby ensuring the synchronous rotating speed output by the two hydraulic motors 21. Because two hydraulic motor 21 all drive the rotation of screening unit 3, consequently, above-mentioned structure has guaranteed that the both ends rotational speed of every screening unit 3 is the same to guarantee that screening unit 3 can not receive torsion, thereby protect screening unit 3's structure.
In a possible design, each of the output ends of the hydraulic motors 21 is fitted with a first chain wheel 22, so that the output end drives the chain wheel to rotate, which in turn drives the screening units 3 to rotate via the chain wheel and the chain.
