Description
Technical field
The present invention relates to mechanical equipment, more particularly to a kind of single lever-type pulverizer.
Background technology
Pulverizer is the machinery that large-sized solid material is crushed to desired size.Structure type have it is a variety of, wherein one
Kind it is that to crush stone be rubble for production concrete in building.The partial structurtes of pulverizer include shell, and shell is equipped with stone
Head import and rubble outlet, shell is interior to be equipped with a pair of of pulverization roller.In use, big stone pours into shell from stone import, after allowing
It is crushed by a pair of of pulverization roller and is dropped out for rubble head, rubble head from rubble outlet.Existing stone crusher has the following disadvantages：
The dust produced during comminution process easily enters through stone import and pollutes environment；Rubble outlet is connected in a manner of normally opened
Continuous discharging, dust emission is big caused by discharging.
The content of the invention
The present invention provides a kind of single lever-type pulverizer for the airborne dust that can reduce import generation, solves existing crushing
The problem of airborne dust that machine import produces is big.
Above technical problem is solved by following technical proposal：A kind of single lever-type pulverizer, including shell, it is described outer
Shell is equipped with stone import and rubble exports, and a pair of of pulverization roller is equipped with the shell, it is characterised in that the wall of the stone import
The water storage ring circumferentially extended along stone import is equipped with portion, the water storage is equipped with the spray orifice of perforation stone import, the shell
Equipped with moisturizing chamber and water storage cavity, the filling pipe is connected by the moisturizing chamber portion's check valve opened towards water storage cavity with water storage cavity,
The water storage cavity is equipped with position by being connected towards the water storage cavity portion check valve that the water storage ring is opened with water storage ring in the shell
Charging energy above the pulverization roller recycles mechanism, the charging energy recycle the hydraulic cylinder that mechanism includes being vertically arranged,
Piston, a piston rod of the hydraulic cylinder of stretching upward being connected on piston in hydraulic cylinder, the drive in hydraulic cylinder
Jacking spring that piston moves up and be connected to thus piston rod on and the punch panel immediately below stone import,
The rodless cavity of the hydraulic cylinder is connected by water channel with the water storage cavity.In water storage cavity and the rodless cavity and water of hydraulic cylinder during use
Full water is filled in road.Stone impacts punch panel with potential energy when declining and drives punch panel to decline, when punch panel declines
Driving piston, which declines, causes the water in hydraulic cylinder to flow to water storage cavity through water channel and cause the hydraulic pressure in water storage cavity to increase, the water of water storage cavity
So that water storage cavity portion check valve is opened after pressure rises, the water in water storage cavity discharges from nozzle after flowing into paring chamber and dust is carried out
Humidify, be not easy to be raised and blown out from stone import after dust wetting, the airborne dust blown out so as to fulfill reduction from stone import.Stone
The space period jacking spring driving punch panel that head does not strike punch panel rises and resets, and the result of reset is so that water storage
The hydraulic pressure of intracavitary reduces, and closed check valve moisturizing chamber portion of water storage cavity portion check valve is opened after the hydraulic pressure in water storage cavity reduces, moisturizing
The water of intracavitary is added in water storage cavity so that water punch panel receives shock next time when in water storage cavity can be driven out.

The pass valve that the eccentric wheel and driving eccentric wheel that drive valve plate on the end face of horizontal drive rod is inserted into the stone import rotate
Motor.
Preferably, the water channel is equipped with the vertical section on the side wall of the shell, sealing is set in the vertical section
Light-blocking block is slidably connected, it is described to close threshold switch and valve opening switch all for the optoelectronic switch with light-blocking block cooperation and be installed on
On the side wall of the shell.It is convenient when mounting arrangement switchs.
Preferably, the input end of the stone import is connected with dilatation section.It can prevent stone when stone import is closed
Overflowed from stone import.
Preferably, be additionally provided with the housing stone to be scattered by punch panel is pooled together be transported to it is the pair of
Hopper between rubble roller.Stone can be caused to recycle mechanism to be reliably pooled to a pair again after scattering by charging energy
With by the reliability of charging between pulverization roller, at the same material head can also drive prevent from crushing caused by the amount that raises up of airborne dust.
It can rotationally be set in support shaft preferably, the pulverization roller includes support shaft and sealing and roll cylinder,
Described roll forms cooling water cavity between cylinder and support shaft, the side face for rolling cylinder is equipped with some watering through holes, the branch
Support axis is equipped with seals against sealing shroud together with the inner peripheral surface for rolling cylinder, and the sealing shroud is equipped with opening.
In use, water is inputted in cooling water tank, so as to play the role of cooling down to pulverization roller, preventing from continuously rolling for a long time causes
Roll a temperature rise and produce surface ruckbildung.Water in cooling water cavity can lead to through opening and with the watering of register
The effect for reducing airborne dust is spilt and is driven in hole.
Preferably, the opening, positioned at the downside of the sealing shroud, the opening direction of the opening is towards positioned at described
