Description
Technical field
The invention belongs to sandstone crushing mechanical field, and in particular to a kind of sand making machine.
Background technology
The application of sandstone is essential that in the prior art, sand making machine type is varied in architectural engineering, main
There are Multichamber sand making machine, mono-roller type sand making machine, impact crusher, rod mill, oscillatory type sand making machine and hammer type sand production machine,
This several sand making machine is typically all using modes such as shock and vibration, grindings.
Existing sand making machine carries out the yielding of roller using spring, and roller pressing materials are to run into intensity to hold higher than spring itself
It can cause to make a concession during the active force received, so that harder material is by the way that but material hardness when producing is uneven, causes spring to be made a concession
The too high low feed back of yield rate for causing material broken of frequency increase and cause yield too low, stone could be become by repeated multiple times
Sandstone, the energy is wasted, consecutive production can not be carried out, time-consuming, operating efficiency is very low.
The content of the invention
The technical problems to be solved by the invention are：A kind of sand making machine of the good efficiency high of particle quality is provided.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of sand making machine, including housing are provided,
Support in housing, fixation roller arrangement, movable roller arrangement and the pressure-regulating device being arranged on support；
The fixed roller arrangement includes the fixing roller being rotatably provided on support, and the movable roller arrangement includes bearing
The drive device that seat, movable roll and driving movable roll rotate, the surface of the fixing roller and movable roll are provided with mutually identical ripple
The wave type flank of tooth, the fixing roller and movable roll, which are parallel to each other, is horizontally disposed with and rotates in opposite directions pressing materials；
The movable roll and drive device are arranged on bearing block；Pulley cunning is respectively equipped between the bearing block and support
Rail is slidably connected；The pressure-regulating device includes hydraulic pressure cylinder assembly, and the hydraulic pressure cylinder assembly includes hydraulic cylinder and by liquid
The hydraulic axis that cylinder pressure stretches out；The pressure-regulating device is connected by hydraulic axis with bearing block, and the hydraulic axis drives bearing block
Adjust the distance between fixing roller and movable roll.
The beneficial effects of the present invention are：1st, the roller surface of sand making machine of the invention is changed to the flank of tooth by plane, eliminates plain-barreled roll
The problem of products obtained therefrom is sheet during sand processed, more tap into the circularity of natural sand；2nd, pressure-regulating device is now changed by original spring
For pressurized oil braking, because the material hardness that client crushes differs, spring runs into intensity in production can hold higher than spring itself
The active force received can cause to make a concession, so that harder material is by the way that but material hardness when producing is uneven, causes what spring was made a concession
The too high low feed back of yield rate for causing material broken of frequency, which increases, causes yield too low, hydraulic braking is now changed to, in material hardness
Not up to oil pressure when disk roller make a concession frequency it is few, more effectively crushed so as to increase productivity；3rd, in the prior art
Made a concession using spring using double dynamical, however after being changed to hydraulic braking it is double dynamical just show it is bad, often result in main shaft suppress it is disconnected,
The too high situation of electric current, judge reason by detection, therefore be changed to single-power.Because the stroke that spring is made a concession under active force is big,
Double dynamical motor force is cancelled out each other, and after being changed to hydraulic braking, the yielding stroke of hydraulic jacking cylinder is determined according to the size of material
It is fixed, if also adopt it is double dynamical will result in the mutual right of dual force, disconnected so as to cause main shaft to be suppressed, the too high situation of electric current goes out
It is existing.By original double roller can rotate it is double dynamical be changed to single-power, reduce energy consumption, it is more energy efficient, more effectively utilize power, reduce
Type floor space.
