Description
Technical field
The utility model relates to a kind of sample classification instrument, particularly a kind of multilayer hummer screen.
Background technology
Common screening plant generally adopts individual layer screen cloth, divides two grain size categories of hanking by material according to the size of sieve mesh.And for some microtests, require high to the grain size category of test material, now just needing to change screen cloth carries out multi-pass operation, just can complete the screening of the material of designated size size, but repeatedly screening in transfer process, material easily mixes impurity, affects result of the test.
Also have and arrange Multilayer vibrating screen, for vibratory sieve, screen cloth screening action needs the vibration realizing both direction, one vibration being perpendicular to screen cloth, for the material of small grain size through sieve mesh, two is the vibrations being parallel to screen cloth, for being spread out by material, avoid the stacking mutual stop of material.For the vibratory sieve of multilayer screen cloth, the design of vibration source is a difficult problem, and selecting of having is obliquely installed screen cloth, utilizes material to replace the vibration being parallel to screen cloth that material is spread out along inclined-plane slide downward.This limits the time of sorting undoubtedly, and material movement is to just carrying out during inclined screen sieve bottom continuing screening.
Summary of the invention
The purpose of this utility model is, for the difficult problem of existing Multilayer vibrating screen vibration source design, to provide a kind of multilayer hummer screen.
The utility model solves the technical scheme that its technical problem adopts: a kind of multilayer hummer screen, comprise body, body top is provided with pallet, pallet is provided with the sieve end,, stacked on top has multiple screen tray at sieve the end, sieve end open top, bottom surface are enclosed construction, screen tray open top, bottom surface are screen cloth, the sieve mesh of each screen tray screen cloth from top to bottom reduces successively, adopt elasticity to be connected between tray bottom with body top and be provided with electromagnetic vibration agencies, the bottom of pallet is also sticked the vibrating motor providing horizontal direction to vibrate.Pallet can stack multilayer screen tray, screen tray is driven to vibrate together by the vibration of pallet, complete screening, pallet vibration comprises the horizontal vibration of up-down vibration and the driven by vibrating motors driven by electromagnetic vibration agencies, completes the process that material is screened and spread out respectively.This device can realize the Synchronous Screening of laminated multi-layer screen tray, can arrange screen tray quantity, realize fine graded according to the sieving and grading demand of material.There is level and up-down vibration in this device, can be spread out by material rapidly, screening effeciency is high simultaneously.
As preferably, the bottom centre of described pallet is sticked the armature of electromagnetic vibration agencies, described body is arranged below armature the solenoid of electromagnetic vibration agencies.There is solenoid to produce varying magnetic field, drive armature up-down vibration.
As preferably, tray bottom surface to be sticked two vibrating motors around armature, two vibrating motor circumferentially 90 degree, interval settings, provides the vibration force of horizontal cross and level longitudinal direction respectively, and two vibrating motors alternately start.Two vibrating motors alternately start, and are alternately spread out to two vertical directions by material, improve screening effeciency, avoid one direction vibrated material to be stacked into dead angle.
As preferably, below described tray bottom surface and between body, be provided with main spring, between Tray side ring Zhou Shangyu body, be evenly provided with some secondary springs.
As preferably, described body is respectively equipped with switch and the indicator lamp of vibrating motor and electromagnetic vibration agencies.
As preferably, described pallet is provided with montant in screen tray bilateral symmetry, is provided with the depression bar being pressed on the superiors' screen tray top between the top of two montants, there is external screw thread at the top of montant the clamp nut of the compression column with fixed that is threaded.
As preferably, described montant is expansion link, and comprise the outer bar that is fixed on pallet and be set in bar in outer bar from upper end, outer masthead portion sidewall is provided with hold-down screw.
As preferably, described clamp nut comprises clamp nut and lower compression nut, sandwiches the upper side and lower side at depression bar two ends respectively.
The utility model adopts pallet vibration to drive mode pallet stacking multi-deck screen disc vibration, drives the sorting of multi-deck screen disc vibration, can realize multipass sort and synchronously carry out, improve the degree that becomes more meticulous of screen cloth sorting by unified vibration source; Meanwhile, this device pallet drives up-down vibration by electric and magnetic oscillation simultaneously, by two vibrating motor driven, two vertical direction horizontal vibrations, improves the efficiency of separation.
