Technical field
Building machinery field is the utility model is related to, more particularly to a kind of testing sieve.
Background technology
Testing sieve is grading to material grains, the instrument of granularity Detection.It is examined, identified by Notified body, Think the sieve for meeting agreement.It is widely used in Granularity Structure and level of the concrete material quality inspection room to concrete and sand material etc. Accurate screening, filtering, the detection matched somebody with somebody, can have accurate understanding to the composition situation such as grading of regeneration concrete, be conducive to improve The quality of the regeneration concrete poured.
Existing Authorization Notice No. is that the Chinese patent of CN203024703U discloses a kind of testing sieve, including vibrations unit, Base unit and screening unit;The vibrations unit includes electromagnet, complex elastic body and reciprocating member, and the reciprocating member is with enclosing The complex elastic body for being around in electromagnet surrounding is connected;The utility model is by interleaved power in electromagnet so that with reciprocating member The related connected screening unit rocking vibration of base being connected, to achieve the purpose that screening.
But multiple screen frames need to be dismantled in the program, when being weighed to the material in each screen frame and weighed one by one, again Need to arrange each screen frame according to pore size order during use, work is in small, broken bits cumbersome and is easier to malfunction.
Utility model content
The utility model provides a kind of testing sieve, it can not dismantle Aggregate of recycled concrete of the screen frame of stacking to screening Weighed.
The above-mentioned technical purpose of the utility model technical scheme is that:A kind of testing sieve, including The vibrating motor of pedestal, the vibratory tray being installed on pedestal and driving vibratory tray vibration, the vibratory tray are equipped with Some screen frames and the fixing device being fixed on screen frame in vibratory tray, be equipped with below vibratory tray on the pedestal with The connecting trays that vibrating motor is connected, the vibratory tray are rotatably arranged on connecting trays, and the screen frame is equipped with and is screened for The discharge port of good sandstone discharge, the screen frame are equipped with the dodge gate for being used for opening and closing discharge port.
By using above-mentioned technical proposal, multiple screen frames, which are stacked, to be placed in vibratory tray, and is filled by fixed Put and be fixed in vibratory tray, during work, vibrating motor drives connecting trays vibration, and then drives vibratory tray vibration, realizes The screening of sandstone.Vibratory tray is hinged with connecting trays, therefore when wanting to pour in aggregate, rotational vibrations support Disk, vibratory tray can drive the screen frame being placed in vibratory tray to tilt, meanwhile, opening is arranged on screen frame and can freely open Dodge gate, the aggregate of screened mistake in screen frame can be poured out, without the multiple screen frames being stacked all are dismantled just It can weigh to aggregate.
Further, rotated on the connecting trays and be equipped with locking screw, be threadedly coupled and be useful in the locking screw The lock nut of vibratory tray is compressed, the vibratory tray is equipped with the lock slots coordinated with locking screw.
By using above-mentioned technical proposal, connecting trays are arranged to hinged with Rotary tray side, by connecting trays Connecting trays and vibratory tray can be fixed with the locking screw and lock slots set respectively in vibratory tray.Therefore, exist When being vibrated to aggregate, locking screw is arranged on lock slots and screws lock nut, connecting trays and vibration can be kept The stability of connection between pallet;When needing to take out the aggregate in screen frame, lock nut is unclamped, by locking screw from lock slots Middle taking-up, vibratory tray are rotated around hinged part, screen frame can be made to be in inclined state, easy to pour out the aggregate in screen frame.
Further, the dodge gate includes the revolving door being articulated with screen frame, and side of the revolving door away from hinged place is set Have the locking buckle revolving door being locked on screen frame.
By using above-mentioned technical proposal, the dodge gate set on screen frame is set to revolving door, and revolving door side passes through work with screen frame Page connection, ensure that the stability of connection, while also allow for the open and close of revolving door, the locking buckle of the opposite side setting of revolving door Revolving door can be locked in screen frame in vibrosieve aggregate, revolving door also can be easily opened when pouring out aggregate.
Further, the face that the revolving door is contacted with screen frame is equipped with the gasket to extend internally.
By using above-mentioned technical proposal, since screen frame is in vibrosieve, in violent rock, aggregate is driven to exist Screen frame internal vibration, tiny aggregate easily flow out at the gap between revolving door and screen frame, cause aggregate quality to reduce, influence entirety Also certain pollution can be caused while the quantity weighed changes to surrounding environment, is set on the contact surface of revolving door and screen frame The rubber ring to extend internally is put, the gap between revolving door and screen frame can be filled up, prevents leaking out for aggregate.
Further, the base bottom is equipped with the cup foot for being used for adjusting base height.
By using above-mentioned technical proposal, since testing sieve pedestal is made of metal, during testing sieve normal use directly with On the one hand the high vibration that ground contact produces can cause ground certain abrasion, influence the balance of whole device, another Aspect can also cause pedestal certain destruction, influence the durability that device uses.Meanwhile cup foot is set to adjustable in length, The height of adjusting cup foot that can be, keeps the stability of testing sieve in due course.
Further, the screen frame bottom is equipped with annular protrusion, is equipped with what is matched with the protrusion at the top of the screen frame Limiting slot.
By using above-mentioned technical proposal, shake since testing sieve needs to be stacked by multiple screen frames when in use Dynamic screening, therefore, at the top of each screen frame and bottom sets corresponding raised and limiting slot respectively, it is ensured that testing sieve is shaking When dynamic, multiple screen frames engage up and down, make to test sieve generally in relatively stable state.
Further, the fixing device includes two clamping screws set perpendicular to vibratory tray and around screen frame, The clamping screw at least two is set by center of circle circumference array of screen frame, on the clamping screw sliding equipped with head cover and Be threaded with clamp nut pressing plate being pressed on screen frame.
By using above-mentioned technical proposal, after screen frame, which is piled up, to be finished, pressing plate is placed on screen frame, screws compression spiral shell Pressing plate is pressed on screen frame by mother, clamp nut, and fixation of the screen frame in vibratory tray can be achieved in pressing plate.
Further, the head cover both sides are equipped with and above carry spanner.
By using above-mentioned technical proposal, since head cover needs frequently to open and close during testing sieve use, Therefore set portable spanner easily to be opened and closed to head cover in head cover both sides, be conducive to improve work efficiency.
