Description
Technical field
The present invention relates to mining machinery technical field, be specifically related to a kind of screen plate mechanism of hammer mill.
Background technology
Hammer mill is made up of casing, rotor, tup, lattice plate, fixed screen deck etc., and the disk on the tup of disintegrating machine and central rotating shaft is hinged, and during work, motor drives central rotating shaft High Rotation Speed, and tup, under the drive of disk, obtains larger impact kinetic energy.Lump material (as lime stone, coal cinder or other brittle materials) is fallen by charging aperture, and enter the workspace of hammer mill, material is subject to the shock of High Rotation Speed tup in this district and carries out primary fragmentation; The material that is broken simultaneously obtains kinetic energy from tup, and high-speed punching is to the lattice plate of disintegrating machine, liner plate and colliding with it and be broken (second-time breakage); Material after second-time breakage falls into the gap of tup dative plate, and is sheared, extrudes, grinds or rebounds in this gap, and meeting with subsequent material, fierce collision and be broken (tertiary crushing) occurs.After above-mentioned 3 fragmentations, material in intense impact, shear and under the effect of colliding with each other etc., be fractured into the granularity of specifying specification, discharge finally by fixed screen deck.Fixed screen deck is arc-shaped sieve plate, is arranged on below rotor, and the two ends of fixed screen deck are contained on crossbeam, fixed screen deck are provided with elementary sieve aperture, can optionally be discharged by material.Hammer mill is a kind of impact crusher conventional at present, has the advantages such as productivity ratio is high, the ratio of reduction large, simple structure, compact conformation and power consumption are less.But in actual production process, a kind of disintegrating machine can only produce a kind of material of specification, and the material being in use greater than primary screen bore dia is easily stuck in sieve aperture, is difficult to cleaning, causes output to reduce; Now need to stop, the tamper cleared up in elementary sieve aperture could continue to use, and this brings inconvenience to production, also makes production cost sharply increase.
Therefore, need a kind of new sieve plate badly and coordinate hammer mill to use, solve hammer mill in above-mentioned technology and can only produce a kind of product of specification, and material is easily stuck in problem sieve plate being difficult to clear up.
Summary of the invention
The invention is intended to the screen plate mechanism that a kind of hammer mill is provided, a kind of product of specification can only be produced to solve hammer mill in prior art, and material is easily stuck in problem sieve plate being difficult to clear up.
The screen plate mechanism of a kind of hammer mill in this programme, comprise fixed screen deck, the bottom of described fixed screen deck is provided with active sieve plate, and the slide that described active sieve plate and casing are provided with is connected, and active sieve plate is provided with the secondary sieve aperture be in elementary sieve aperture on same axial line; Described active sieve plate is provided with push-pull device at fixed.
Operation principle of the present invention and beneficial effect are: the bottom of fixed screen deck is provided with active sieve plate, and comprise at least two-layer sieve plate, the slide that active sieve plate and casing are provided with is connected, and active sieve plate can slide on chute; Active sieve plate is provided with the secondary sieve aperture be in elementary sieve aperture on same axial line, elementary sieve aperture can overlap completely with secondary sieve aperture or partially overlap, under the effect of push-pull device at fixed, active sieve plate is moved along chute, fixed screen deck and active sieve plate are staggered, and the center of elementary sieve aperture is departed from the center of secondary sieve aperture gradually, and the effective dimensions of sieve aperture from big to small, the selection of sizes can be provided, make same hammer crushing function produce the material of plurality of specifications; When material is stuck on elementary sieve aperture in use procedure, also can pass through mobile active sieve plate, increase the effective dimensions of sieve aperture, avoid feed blocking sieve aperture and cause output to reduce.The present invention, by being staggeredly located out upper and lower sieve plate, obtaining the sieve aperture of different size, thus produces the product of different size, overlapped by elementary sieve aperture, can remove tamper in time when feed blocking sieve aperture with secondary sieve aperture.
Further, the sleeve that described push-pull device at fixed comprises rocking handle, the screw rod be connected with rocking handle and is arranged on active sieve plate, the through hole that described sleeve one end is provided with is less than sleeve dimensions, described screw rod runs through the inside that its termination of casing is positioned at sleeve, pass through rotation crank, screw rod can be ejected inwards or outwards, the convenient movement to active sieve plate.
Further, the termination of described screw rod is provided with clamp, and the size of described clamp is greater than clear size of opening.When screw spiral moves inwards, clamp withstands casing promotion active sieve plate and moves inwards, and when screw spiral outwards moves, clamp moving, to through hole, is stuck on sleeve, and screw rod pulls active sieve plate outwards movement.
