Description

Weighing hopper

Technical Field

The utility model relates to a concrete production facility, more specifically say, it relates to a weighing hopper.

Background

A proportioning machine, also called a concrete proportioning machine and a gravel automatic proportioning machine, is an automatic device for quantitatively distributing gravel or concrete, is mainly applied to the concrete construction industry, and replaces manual platform scales or volume metering and other modes.

The utility model discloses a concrete batching fill is disclosed in the chinese utility model patent of publication number CN205238278U, including the support of hopper body, support hopper body, the upper portion of hopper body is equipped with the feed inlet, the lower part of hopper body is equipped with a plurality of discharging pipes, a plurality of discharging pipes communicate with each other with the hopper body, all is equipped with control flap on every discharging pipe, the inside top that is located the discharging pipe of hopper body is equipped with the stirring of slope respectively and holds together, the rear end that the stirring was held together is equipped with rotary drive device, rotary drive device is connected with the motor. The concrete batching hopper has the advantages of rapid and uniform discharging.

However, after some great grit of density dropped into the batching and fought, because the ejection of compact pipeline of above-mentioned batching fill is less, the contact is inseparable between the grit, easily appears the grit and supports tight sluice gate, leads to the sluice gate to open the condition not.

SUMMERY OF THE UTILITY MODEL

To current technical problem, the utility model provides a weighing hopper prevents long-pending material bottom plate through setting up in hopper body bottom, avoids the sluice gate because of long-pending material inseparable or the card shell condition of not opening, improves production efficiency.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a weighing hopper comprises a rack and a hopper body fixedly arranged on the rack, wherein two arc hopper doors are symmetrically arranged at a discharge port of the hopper body, two ends of each hopper door are hinged with the side surface of the hopper body, and a control mechanism for controlling the hopper doors to open and close is arranged on the rack;

two anti-accumulation bottom plates are symmetrically arranged at the discharge outlet of the hopper body and are positioned in the hopper door and hinged with the discharge outlet of the hopper body.

Through adopting above-mentioned technical scheme, after toward this internal material of throwing of hopper, because the grit is piled up closely and is piled up on the sluice gate, lead to the unable circumstances of opening of sluice gate appearing, seriously influence production efficiency, prevent long-pending material bottom plate setting on the sluice gate, the grit fill that needs the batching is piled up and is preventing long-pending material bottom plate, during the ejection of compact, directly open the sluice gate, prevent that long-pending material bottom plate receives the pressure of grit and open downwards, the grit falls, the grit card can not appear and can not open the situation of sluice gate in fighting the crack, and production efficiency is improved.

Furthermore, the hinge point of the material accumulation preventing bottom plate is provided with a first torsion spring, one end of the first torsion spring is fixedly connected with the hopper body, and the other end of the first torsion spring is fixedly connected with the material accumulation preventing bottom plate.

Through adopting above-mentioned technical scheme, the setting of torsional spring for after the whole ejection of compact of grit, prevent long-pending material bottom plate and can reset, the sluice gate can normally close.

Furthermore, a vibration motor is fixedly arranged on the outer side wall of the hopper body.

Through adopting above-mentioned technical scheme, during the ejection of compact, open vibrating motor, can shake out all the grit that remains on the hopper body inner wall, still can make the smooth ejection of compact of grit that hopper body bottom was encircleed in addition.

Furthermore, bulges are uniformly distributed on the inner wall of the hopper body.

Through adopting above-mentioned technical scheme, the effect of thickening this body lateral wall of hopper is played on the one hand to the arch, and when can preventing to throw the material, the grit damages the lateral wall of hopper body, and on the other hand plays long-pending effect of expecting, and in few grit exists the gap between the arch, the material of throwing for other grit played certain cushioning effect, when the ejection of compact, can open vibrating motor, with remaining grit in the gap between the arch all shake out.

Further, control mechanism includes handle, connecting rod, connecting plate, fixed plate and four articulated slab, the fixed plate is located the both ends of hopper door and fixed with the lateral wall of hopper body, two the both ends of articulated slab are articulated, and the both ends that two articulated slabs kept away from the pin joint rotate with the fixed plate is inboard respectively and are connected and hopper door is articulated, the articulated slab passes through gear revolve with the fixed plate and sets up, the one end of connecting plate is articulated with the pin joint of two articulated slabs, and its other end rotates with the connecting rod and sets up, the both ends and the frame of connecting rod rotate and set up, the handle perpendicular to connecting rod just is fixed with the connecting rod, one fan of keeping away from the connecting plate in the hopper door is opened and close through.

Through adopting above-mentioned technical scheme, when needing the ejection of compact, the operator presses the handle downwards, and the handle drives the connecting rod and rotates, and connecting rod pulling connecting plate, connecting plate pulling articulated slab to gear on the fixed plate is the pivot, and the articulated slab of gear both sides drives two fill doors and opens.

Furthermore, the top of handle is provided with the barb, the lateral wall of hopper body articulates there is the link of locking handle.

Through adopting above-mentioned technical scheme, the handle passes the link, and the link locks each other with the barb, prevents that the phenomenon of handle emergence maloperation from avoiding this internal no grit of hopper in addition to appear the handle because of the dead weight phenomenon that drives the sluice gate and open that pushes down.

Further, the feed inlet department symmetry of hopper body articulates there are two dust guards, the articulated punishment department of dust guard is provided with the second torsional spring, the one end and the fixed setting of dust guard of second torsional spring, its other end and hopper body fixed connection.

Through adopting above-mentioned technical scheme, when throwing the material, the grit falls into this internal after of hopper, and the dust guard receives the effect of torsional spring and resets to avoid the tumbling of this internal grit of hopper to cause the dust to fly and dance, reach cleaner production's effect.

Furthermore, the hopper body is fixedly provided with a flange plate for preventing the dust-proof plates from rotating over at the opening of the two dust-proof plates.

Through adopting above-mentioned technical scheme, the flange board is avoided the dust guard to receive the effect of torsional spring and the condition that takes place to change excessively.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the material accumulation preventing bottom plate is arranged on the hopper door, so that the effects of supporting sand and blocking the sand and the hopper door are achieved, the situation that the hopper door cannot be opened due to tight sand accumulation or the sand and stone being clamped in the gap of the hopper door can be avoided, the follow-up repair and cleaning of the hopper door by workers are correspondingly reduced, and the production efficiency is improved;

(2) through setting up arch and vibrating motor, the lateral wall of protruding thickening hopper body, a small amount of grit is amasss between the arch, can play the cushioning effect to most grit, and the hopper body inside wall can not be washed out by the grit promptly to the arch, improves the life of weighing hopper, and vibrating motor makes a small amount of grit between the arch all fall down, avoids appearing the inside condition of long-pending material of hopper body.
