Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
See fig. 1-2.
The invention relates to a sand and stone discharge opening structure, which comprises: the inner cover 2 is arranged in the outer cover 1 which is hollow inside and is communicated with two ends through an interval adjusting piece 3; the middle part of the inner cover 2 is a through hole, and the width of the interval of the through hole in the middle part can be automatically adjusted.
Through the volume interval distance of 3 adjustment dustcoats 1 and 2 inner covers of interval regulating part, when the granule increase of grit blockked up at inner cover 2, the interval width of inner cover 2 automatic adjustment middle part through-hole, the grit extrusion discharge that will block up under the extrusion of upper sandstone has solved the holistic discharge port structure of rigidity inside the breaker and has taken place to damage can not take place the grit exhaust problem, has avoided the motor on the breaker to burn out the condition and has taken place.
The interval adjusting member 3 is elastic rubber or a spring.
The flexible tensioning subassembly 4 of installing runs through on dustcoat 1 side, the 3 other ends of flexible tensioning subassembly and inner cover 2 fixed connection, and the distance between dustcoat 1 and the inner cover 2 can be adjusted to flexible tensioning subassembly 4.
The telescopic tensioning component 4 is a telescopic air rod or a telescopic hydraulic rod.
