Regulator is by pressure regulation reducing motor 11, two groups of pressure regulating member, pressure regulation thrust bearings 17, organizes elastic damping member (the elastic damping member that this example adopts shock-absorbing spring to combine with the rubber air spring shock absorber also can adopt the elastic damping member of other form) and vibration proof mounting 20 and two groups of pressure sensor devices 21 formations more.Be provided with charging aperture 30 in the middle of the top of case 30, its underpart also is provided with discharging opening (seeing the dotted line of accompanying drawing 1 bottom).Movable roll bearing block 23 and stationary roller shaft bearing 28 are installed the front and back side that is positioned at case 30 on frame 1 respectively, and movable roll bearing block 23 is quick condition, and stationary roller shaft bearing 28 is stationary state; The movable roll bearing block 23 that is the quick condition device connects with vibration proof mounting 20 through two pressure sensors 21 of device in forward and backward side respectively; Device has many group shock-absorbing springs 19 (this example adopts two-layer arrangement up and down, ten shock-absorbing springs 19 altogether on the another side of vibration proof mounting 20, also can adopt the shock-absorbing spring 19 of other quantity) and two groups of rubber air spring shock absorbers 18 (this example adopts two-layer arrangement up and down, amounts to four rubber air spring shock absorbers 18, also can adopt the rubber air spring shock absorber 18 of other quantity); The other end of shock-absorbing spring 19 and rubber air spring shock absorber 18 connects pressure regulation thrust bearing 17.
Pressure regulating member is to be made of pressure regulation casing 32, pressure regulation travelling gear 9, pressure regulation gear 2, pressure regulation screw axis 4, pressure regulation screw mandrel axle bed wallboard 33, thrust metal 7, thrust bearing 8, thrust bearing gland 10, lining 15, look nut 12, feather key 13 and thrust bearing flange 16.Pressure regulation screw mandrel axle bed wallboard 33 is housed on the pressure regulation casing 32, install thrust metal 7 on this pressure regulation screw mandrel axle bed wallboard 33, one end of pressure regulation screw axis 4 installs thrust bearing 8 backs, passes thrust metal 7 and pressure regulation screw mandrel axle bed wallboard 33 again, installs pressure regulation gear 2 again; Pressure regulation screw axis 4 passes pressure regulation gear 2 backs, installs pressure regulation gear lining 6 again, installs bearing 5 again, and bearing gland 3 devices of bearing set 5 are on the wallboard of pressure regulation casing 32 sides.The screw mandrel end 14 of the other end of pressure regulation screw axis 4 is installed in the look nut 12, and the termination of look nut 12 connects thrust bearing flange 16, and thrust bearing flange 16 is connected on the pressure regulation thrust bearing 17.Have axial gathering sill on the outer cylinder of look nut 12, device guiding key 13 in this gathering sill, the lining 15 that endoporus and this feather key 13 are fixed is installed in the endoporus of thrust bearing gland 10 1 ends, and the other end of thrust bearing gland 10 arrives at thrust metal 7 and thrust bearing 8.Two groups of pressure regulating member are installed respectively on the left part of frame 1, its upper unit pressure regulation reducing motor 11, device pressure regulation travelling gear 9 on the output shaft of pressure regulation reducing motor 11, this pressure regulation travelling gear 9 simultaneously with two groups of pressure regulating member in 2 engagements of pressure regulation gear, and the thread rotary orientation on the screw mandrel end 14 of pressure regulation screw axis 4 terminations in two groups of pressure regulating member is opposite.
Before the use, adjust the precompression of shock-absorbing spring 19 and rubber air spring shock absorber 18 earlier, and configure the operation condition parameter of pressure sensor 21.During use, the power of mechanical power device 26 is after deceleration device 25 slows down, export rightabout rotation respectively by its two output shafts, (at this moment: movable roll 22 is made clockwise direction and is rotated to pass to movable roll 22 and stationary roll 27 respectively through movable roll shaft shaft coupling 24 and stationary roller shaft shaft coupling 29 again, stationary roll 27 is done counterclockwise to rotate, see accompanying drawing 1), material (that is: sandstone or cobblestone or other material used of system sand) is entered the inner chamber of case 30 by charging aperture 30, by between feeding two rollers, under the effect of moderate strength compression, material pushes mutually, stone roller is cut fragmentation, and is discharged by the discharging opening of case 30 bottoms.Because the compression intensity between two rollers is medium, thereby, grind in the finished product of cutting after the fragmentation to contain the powder rate lower, become the sand coarse aggregate ratio height, product becomes cube, grain shape is good, bulk density is big.
Cut in the shattering process at stone roller, when pressure sensor 21 detects pressure between movable roll 22 and the stationary roll 27 when less than normal, pressure sensor 21 will be exported a boost pressure signal, driving pressure regulation reducing motor 11 is just changeing, and by 2 rotations (switched in opposite of two pressure regulation gears 2) of pressure regulation travelling gear 9 drive pressure regulation gears, and then, drive pressure regulation screw axis 4 and rotate (turning to of two pressure regulation screw axis 4 is also opposite), thereby, driving look nut 12 moves right (because the thread rotary orientation on the screw mandrel end 14 of two pressure regulation screw axis 4 terminations is opposite, thereby, although the switched in opposite of two pressure regulation screw axis 4, the moving direction of its look nut 12 is identical), the pressure regulation thrust bearing 17 that promotes to connect with it moves right, thereby compression shock-absorbing spring 19 and rubber air spring shock absorber 18 carry out supercharging; When pressure sensor 21 detects pressure between movable roll 22 and the stationary roll 27 when suitable, pressure sensor 21 will be exported a stop signal, and pressure regulation reducing motor 11 is stopped operating.Otherwise, when pressure sensor 21 detects pressure between movable roll 22 and the stationary roll 27 when bigger than normal, pressure sensor 21 will be exported a depression signal, drive 11 counter-rotatings of pressure regulation reducing motor, thereby, drive look nut 12 and be moved to the left, discharge shock-absorbing spring 19 and rubber air spring shock absorber 18, reduce pressure.
Pressure roller compacting sand machine can be used for utilizing materials such as sandstone, cobblestone to prepare sand for building in of the present invention, also can be used for the preposition broken mill of grinding system; Can be widely used in fields such as building, building materials, mine.
