Quartz sand rolling device, operation principle is summarized as follows.
Motor a 11a, a motor 11a is opened to be transferred to power on main shaft 3 after V belt translation slows down, it is main
Little gear 6 on axle 3 is rotated, and little gear 6 is engaged with canine tooth wheel disc 7, and canine tooth wheel disc 7 is rotated, meanwhile, little gear 6 and gear wheel
The engaged transmission of disk 7 is double reduction transmission, i.e., the rotating speed of canine tooth wheel disc 7 is relatively low and its output torque is larger.Canine tooth wheel disc 7 is in footpath
Under being acted on to locating wheel 10 so that it does fixed-axis rotation；Meanwhile, drawing of the canine tooth wheel disc 7 in axially position wheel 26 and straight down
Under power and Action of Gravity Field so that it is unable to axial float.
Under the drive of canine tooth wheel disc 7, the rotating disk 12 being connected with canine tooth wheel disc 7 also does fixed-axis rotation therewith.With rotating disk 12
Fixed-axis rotation is also done in a pair of swing arms 13 of connection, and the interface slot 13b in this pair of swing arm 13 promotes trunnion axis 17 to do fixed-axis rotation, water
The drive simultaneously of flat axle 17 rolls stone roller 25 and does composite rotation（Stone roller 25 is rolled i.e. around the rotation of trunnion axis 17, while around big
The rotating shaft revolution of toothed disc 7）.So rolling stone roller 25 just can roll quartz sand.
In stone roller 25 and the rotation process of trunnion axis 17 is rolled, the locator 19 being connected with trunnion axis 17 is in upper locating shaft 16
And fixed-axis rotation is done under the common constraint of lower locating shaft 23, so just play constraint work with the rotation of trunnion axis 17 to rolling stone roller 25
With preventing from rolling stone roller 25 along the direction play of trunnion axis 17, so as to destroy its fixed-axis rotation.
Embodiment two
As described in embodiment one, and make the modification of following technical characteristic and increase.
A number motor 11a is set to 9.5KW.
Also through one U-shaped pinion stand 5 of bolt connection on the inside of the other end flap seat 2b of hanging beam 2, also through axle on the pinion stand 5
Hold one main shaft 3 of connection, the main shaft in pinion stand 5（3）On also connect a little gear 6 engaged with canine tooth wheel disc 7, should
Side main shaft 3 is through spindle hole 2a and outer one end for extending the top of hanging beam 2 also connects belt wheel 4；The belt wheel 4 passes through 3 V-type bands and volume
Determine No. two motor 11b that power is 15KW to connect, No. two motor 11b are consolidated in hanging beam 2.
Quartz sand rolling device, operation principle is summarized as follows.
In initial start, while opening a motor 11a and No. two motor 11b, each motor passes through band respectively
Power is transferred on corresponding main shaft 3 after gear reduction, the little gear 6 on each main shaft 3 is rotated, little gear 6 and gear wheel
Disk 7 is engaged, and canine tooth wheel disc 7 is rotated, meanwhile, little gear 6 is double reduction transmission, i.e. canine tooth with the engaged transmission of canine tooth wheel disc 7
The rotating speed of wheel disc 7 is relatively low and its output torque is larger.Canine tooth wheel disc 7 is under the effect of radial positioning wheel 10 so that it does fixed-axis rotation；
Meanwhile, under pulling force and Action of Gravity Field of the canine tooth wheel disc 7 in axially position wheel 26 and straight down so that it is unable to axial float.
Under the drive of canine tooth wheel disc 7, the rotating disk 12 being connected with canine tooth wheel disc 7 also does fixed-axis rotation therewith.With rotating disk 12
Fixed-axis rotation is also done in a pair of swing arms 13 of connection, and the interface slot 13b in this pair of swing arm 13 promotes trunnion axis 17 to do fixed-axis rotation, water
The drive simultaneously of flat axle 17 rolls stone roller 25 and does composite rotation（Stone roller 25 is rolled i.e. around the rotation of trunnion axis 17, while around big
The rotating shaft revolution of toothed disc 7）.So rolling stone roller 25 just can roll quartz sand.
After machine runs well, a motor 11a is closed, unilateral driven machine work is carried out by No. two motor.
In stone roller 25 and the rotation process of trunnion axis 17 is rolled, the locator 19 being connected with trunnion axis 17 is in upper locating shaft 16
And fixed-axis rotation is done under the common constraint of lower locating shaft 23, so just play constraint work with the rotation of trunnion axis 17 to rolling stone roller 25
With preventing from rolling stone roller 25 along the direction play of trunnion axis 17, so as to destroy its fixed-axis rotation.
