Corresponding fluid power system one side is provided with link on the described housing, sells between the cylinder bar of described link and the hydraulic cylinder of described fluid power system to be connected.
Described rotating disk is provided with the two circle pin-and-holes of arranging with the annular array form, sell between described hammer body and the rotating disk to be connected, can adjust the position of hammer body on rotating disk according to the degree of wear of hammer body end, and then the gap between adjustment hammer body and the sieve plate, the assurance crushing effect.
Described bottom of shell is provided with bearing support, and described bearing support is provided with slide rail, and described housing is provided with the slide mechanism of corresponding described slide rail, so that left shell or right shell body are mobile under the driving of fluid power system, and convenient maintenance to each parts in the casing.
Be connected with connecting bolt by flange between the described left and right housing.
The beneficial effects of the utility model are:
1, motor forward and backward alternate run, drive power transmission shaft and on rotor assembly forward and backward alternate rotation, then do not need to open the broken end face of casing transposing hammer body, crushing action just can hocket on the two sides of hammer body end, not only crushing effect is good, and significantly improves operating efficiency; The sieve plate, the wear liner that arrange in hammer body end and the casing simultaneously are even, have prolonged service life.
2, by " U " type sieve plate rotor assembly is surrounded, the screening scope increases, and has improved screening effeciency.
3, for the ease of the miscellaneous part in maintenance, adjustment, replacing sieve plate, hammer body and the casing, adopt left and right housing assembling form, and utilize fluid power system left shell or right shell body to be pulled open (drawing box), save manpower.
4, the casing top arranges charge door and has replaced the form that charge door is offered in the casing side, has guaranteed material not to be thrown away casing when rotor assembly replaces forward and backward work, causes waste.
