Description

A kind of moveable crusher of sieve

Technical field

The present invention relates to breaking device fields, and in particular to a kind of moveable crusher of sieve.

Background technology

Mine crushing machine is also stone crusher, refers to that content of the granularity more than three millimeters accounts for 50% or more total withdrawal rate in discharge Size reduction machinery；It is numerous that mine crushing machine is widely used in mine, smelting, building materials, highway, railway, water conservancy and chemical industry etc. Department.

Existing mine crushing machine includes hammer mill, jaw crusher etc., and wherein hammer mill is mainly by being crushed Casing, the feed space positioned at broken casing top, the crushing chamber in the middle part of broken casing and the sieve positioned at broken casing lower part Room is selected to constitute；And it is crushed indoor broken rotor, it is the core of crusher；Pass through the high speed rotation of broken rotor, broken rotor On the crusher hammer that is rotatably connected to while struck to fragment, so that fragment is carried kinetic energy；By mine crushing machine institute The hardness of broken most of material is big, in addition fragment carries kinetic energy, it is very big to the shock or frictional force of crusher inner wall, therefore The casing of crusher is all very thick and heavy；Currently, when the parts of most of crusher inside it damage, all pass through The casing for dismantling crusher could be replaced or repaired to the parts of damage；Which results in zero inside crusher When part damages, replaces or repair must enable hanging device, when lifting casing, must pay attention to the peace of maintenance personal Entirely, in order to avoid casing unexpected injury is to maintenance personal, therefore Single Maintenance the time it takes is of high cost.

And during hammer mill use, when the grain size of fragment be simultaneously greater than sieve pore aperture and crusher hammer with When spacing between sieve, fragment is rolled by the crusher hammer of swing, alignment again is crushed；But it is sometimes broken on sieve The grain size that minces is only slightly larger than the aperture of sieve pore, but less than the spacing between crusher hammer and sieve, the crusher hammer that this is is just Fragment can not be rolled and it is crushed again, and the fragment of such size leads to its product since crusher hammer can not be taken away Tire out on sieve, and block sieve pore, causes the local stoppages or completely plugged of sieve；And such blocking is caused, present Conventional means are exactly to dismantle the casing of crusher, and take out sieve and cleared up, and due to time cost height, cause making for crusher It is reduced with rate.

In conclusion being badly in need of a kind of crusher now, solve to be merely greater than the hole of sieve pore when the grain size of the fragment on sieve Diameter, but when less than spacing between crusher hammer and sieve, it can directly clean up the tamper；Taking-up or replacement can be facilitated again The problem of sieve.

Invention content

The invention is intended to provide a kind of moveable crusher of sieve, solve to be merely greater than when the grain size of the fragment on sieve The aperture of sieve pore, but when less than spacing between crusher hammer and sieve, it can directly clean up the tamper；Taking-up can be facilitated again Or the problem of replacing sieve.

The moveable crusher of a kind of sieve in this programme, including it is located at the indoor sieve of screening, the sieve bottom surface At least two lifting members being mounted in screening chamber interior walls are connected with, the screening room is equipped with passes in and out screening room for sieve Inlet and outlet.

The operation principle and advantage of this programme：By the effect of lifting member, the indoor sieve of screening can be made complete At the movement on vertical direction；If the grain size of the tamper on the sieve is excessive, cause its cannot by the sieve pore on sieve, but When to be its grain size have less than crusher hammer to spacing between sieve, so that it may sieve is promoted, between shortening between crusher hammer and sieve Away from making spacing be equal to or less than the grain size of fragment, and then by the impact of crusher hammer effect, tamper is broken into Meet mesh size；If when fall into the tamper grain size on sieve it is excessive and itself hardness it is big when, to avoid tamper pair When crusher hammer causes damage, so that it may decline sieve, and then avoid impact of the crusher hammer to fragment.

Meanwhile when damaging occurs in sieve or sieve is by Severe blockage, rapidly taken by screening the inlet and outlet on room Go out or replace sieve, avoids after screening room must being dismantled in the prior art, just can be taken off or replace the feelings of sieve Condition；The efficiency that sieve takes out or replaces is improved, the service efficiency of crusher is increased.

Further, the lifting member mainly by hydraulic mechanism at；Since sieve can be collided by the high speed from fragment, If if the lifting member of support sieve cannot provide enough support forces, sieve is may result under the impact of fragment, it is separate Broken rotor, and then increase the spacing between broken rotor and sieve；Since hydraulic pressure function bears stronger power, therefore select its conduct Lifting member；

Further, further include the bottom plate that through-hole is equipped with plate, bed bolt, which is connected to, screens room discharge outlet, and through-hole Match with the outlet of screening room, the hydraulic press is mounted on bottom plate；Since bottom plate can be removed, by the way that hydraulic press is mounted on bottom It is convenient when hydraulic press breaks down on plate, it can rapidly remove and replace failed hydraulic machine.

Further, four angles of the sieve bottom surface are connected separately with wing plate；To avoid hydraulic press by after screen filtration Fragment is hit, therefore hydraulic press should be placed at separate sieve, therefore by the way that wing plate is arranged on sieve, to increase sieve and hydraulic press Between spacing, and then hydraulic press can be mounted remotely to greatest extent the place of sieve.

Further, the end of the hydraulic press telescopic segment is T shapes, and the wing plate is equipped with the end with hydraulic press telescopic segment Matched sliding slot；By the setting of sliding slot, to increase the contact area of wing plate and hydraulic press telescopic segment, to increase wing plate Stabilization between hydraulic press reduces the probability that wing plate slides from hydraulic press.
