Description

Potential energy water spray cleaning type truck mixer and concrete production method
Technical field
The present invention relates to concrete production equipment more particularly to a kind of potential energy water spray cleaning type truck mixers.
Background technology
Concrete, referred to as " concrete(tóng)”:Refer to by cementitious material by the cementing integral engineered composite material of aggregate General designation.One word of concrete usually said refers to making cementitious material, sand, masonry aggregate with cement;With water(Additive can be contained and mixed Close material)Coordinate by a certain percentage, it is agitated obtained by cement concrete, also referred to as normal concrete, it is widely used in building work Journey.Concrete such as concrete is mixed and is produced by the way that water, aggregate and cementitious material are stirred by agitator 's.The same basic structure of stirring includes staving and blender, and staving is equipped with feed inlet and concrete outlet, and blender includes stirring The motor of axis, the stirring blade being located in agitator being arranged on agitating shaft and driving agitating shaft rotation.Feed inlet has staving Upper end all open wide and constitutes, stirring motor is arranged outside the bottom wall of staving, when material is poured by feed inlet be easy produce Raw dust raising phenomenon;Water leaks out through the junction of shaft and staving bottom wall, needs to seal here in order to prevent, and due to producing ring Bearing damage and leakage phenomenon are easy tod produce at the influence shaft in border and the sealing of staving.
Invention content
The present invention provides a kind of potential energy of airborne dust that can be reduced and be generated when production spray water cleaning type truck mixer, Solve the problems, such as existing blender using when easy to produce dust raising phenomenon.
The above technical problem is solved by following technical proposal:A kind of potential energy water spray cleaning type truck mixer, Including tank body and blender, the tank body is equipped with feed inlet and concrete outlet, and the blender includes agitating shaft, is arranged and stirring The stirring motor of the stirring blade and driving stirring blade rotation on axis is mixed, the feed inlet is located at the upper end of the tank body, institute The cloth water ring for being equipped in the wall portion of feed inlet and being circumferentially extended along feed inlet is stated, the water distribution is equipped with the water spray of perforation feed inlet Hole, the tank body are equipped with replenisher tank and transition water pot, and the water supply pipe is same by the first check valve opened towards transition water pot Transition water pot is connected to, and the transition water pot is connected to by the second check valve opened towards the cloth water ring with cloth water ring, described Material potential energy recovering mechanism is equipped in tank body, the material potential energy recovering mechanism includes the water vat being vertically arranged, the work in water vat The resetting spring that piston rod, the driving piston in water vat for stretching out water vat upward fill in, being connected on piston move up With connection on the piston rod and splicing plate immediately below the feed inlet, the rodless cavity of the water vat is by runner with the mistake Cross water pot connection.When use transition water pot, water vat rodless cavity and runner in fill full water.The technical program is in use, energy Potential energy docking flitch when enough being declined using material is impacted and splicing plate is driven to decline, when splicing plate declines under driving piston So that the water in water vat flows to transition water pot through runner and the hydraulic pressure in transition water pot is made to increase, the hydraulic pressure of transition water pot rises drop Afterwards so that the second check valve is opened, the water in transition water pot is discharged from nozzle to dust wetting after flowing into paring chamber, and dust adds It is not easy to be raised and blown out after wet, to realize reduction airborne dust.Material, which does not strike, resets bullet in the space period of splicing plate Spring driving splicing plate rises and resets, and the result of reset is the hydraulic pressure reduction so that in transition water pot, the hydraulic pressure in transition water pot Second the first check valve of closed check valve is opened after reduction, and the water in replenisher tank adds in transition water pot so that under splicing plate Water when once receiving shock in transition water pot can be driven out.
Preferably, stirring motor is connected in the water vat, the tank body is located at the space structure of the lower section of the water vat At stirring space, the stirring blade is located in the stirring space.Compact in design is convenient.Concrete is not easily penetrated into agitating shaft Cause to damage with the junction of bucket, and without being sealed.
The invention also includes water spray reliability hoisting mechanism, the water spray reliability hoisting mechanism includes closing the charging The barrier gate whether flashboard of mouth, the actuating unit of driving flashboard folding, detection piston reach setting final position switchs, detection is lived That fills in the initial position for whether reaching setting opens a sluice gate switch and control unit, and barrier gate switch detects that piston reaches the terminal of setting Described control unit makes the actuating unit that the flashboard be driven to close when position, opens a sluice gate switch and detects that piston reaches setting Described control unit makes the actuating unit that the flashboard be driven to open when initial position.Material can be avoided continuously to decline( I.e. splicing plate is not short by the time interval impacted)And the time for causing piston not reset, it can not be reliable so as to cause water The phenomenon that ground sprays generates.
