Description

Quick unloading structure of concrete sand washer

Technical Field

The application relates to the technical field of sand washers, in particular to a quick unloading structure of a concrete sand washer.

Background

At present, places such as concrete mixing plants, mines, gravel plants and building material plants, where gravel is needed, can be cleaned by sand washers, the sand washers generally use bucket wheel sand washers, the sand washers of the bucket wheel sand washers can firstly take out the gravel in the feed chute through the blades arranged in multiple stages on the peripheral wall of the sand washer during rotation, and the gravel falls off from the blades to the discharge opening after being cleaned.

In the related art, a Chinese patent with publication number CN202122563417.7 proposes an improved wheel bucket type sand washer, which comprises a wedge-shaped rinsing bath and a rinsing wheel rotatably arranged in the middle of the upper end of the wedge-shaped rinsing bath, wherein a feeding hole and a discharging groove are further fixed on two ends of the wedge-shaped rinsing bath. When the sand washer operates, the sandstone needing cleaning is thrown into the wedge-shaped rinsing bath through the feed inlet, then the rinsing wheel rotates the aquatic rotation of in-process drive sandstone at the wedge-shaped rinsing bath, when the sandstone moved to the blown down tank top, the sandstone slided from the rinsing wheel under the action of gravity and dropped to the blown down tank from the eminence, carries out the ejection of compact from the blown down tank at last.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: grit rotates to the discharge gate (the blown down tank in the above-mentioned file) top along with washing the emery wheel (the washing wheel in the above-mentioned file), because the blade is multistage setting, there is the difference in height between the grit on the different blades to the discharge gate, when the upper strata grit that lies in on the blade of eminence slided from the blade, because the difference in height of grit and discharge gate is great for the grit of eminence drops and can the spill discharge gate in discharge gate department, leads to the ejection of compact efficiency reduction of washing the sand.

SUMMERY OF THE UTILITY MODEL

In order to improve the problem that can the splash discharge gate lead to the grit to be washd back discharging efficiency and reduce in the eminence grit falls the blown down tank, this application provides a concrete sand washer structure of unloading fast.

The application provides a pair of concrete sand washer structure of unloading fast adopts following technical scheme:

the utility model provides a concrete sand washer structure of unloading fast, connects the washing wheel at washing machine this internal including washing machine body and rotation, and washing machine body one end is provided with the discharge gate, including fixed connection in washing machine body the play flitch and the fixed connection of discharge gate department are in the mounting panel of washing machine body bottom, the activity is provided with on the mounting panel connects the sand board, it is located to connect the sand board one side of mounting panel is kept away from to go out the flitch, it is right to be provided with on the mounting panel connect the sand board to be close to wash the elevating system that emery wheel one end goes up and down.

Through adopting above-mentioned technical scheme, when washing the emery wheel when washing the internal rotation of sand machine, the grit rotates to the one side that the sand machine body is close to the discharge gate along with the blade on the sand washing wheel when, the grit landing on the low department blade of sand washing wheel is to the play flitch, adjust elevating system, order about and connect the sand board to be close to the one end lift to suitable position of washing the emery wheel, accept the grit of landing on the blade of sand washing wheel eminence, thereby avoid the grit that the eminence dropped to strike out the discharge gate that the flitch flew, the problem of grit is washed back discharge efficiency is improved.
