Abstract

The utility model relates to a planet-gear driven terrazzo grinder. In the planet-gear driven terrazzo grinder, a star shaped frame is arranged on a driven shaft; a central gear is fixed on the transverse ribbed slab of the machine body; a planet gear shaft is arranged on the star shaped frame; a grinding disc with a damper spring and a planet gear are fixed on the planet gear shaft coaxially; the planet gear and the central gear are engaged. The grinding disc can do revolution around the driven shaft, and simultaneously, the planet gear rotates around the central gear to drive the grinding disc to do autorotation at the time of working. Thus the working conditions of the grinding process and the contact between the grinding head and the earth surface can be improved, and the work efficiency can be near doubled.

Description

Planet-gear driven terrazzo grinder

The utility model relates to a kind of ground polishing device.

Existing terrazzo machine, its mill that is embedded with diamond or emery wheel bistrique is fixed on the driven axle; During operation, mill is around the rotation of driven axle axis, and the relative motion that produces when contacting with ground by bistrique reaches the purpose with the ground polishing; Though its work efficiency is higher, but still can not satisfy present needs.

Task of the present utility model provides a kind of mill Ji and can revolve round the sun, simultaneously efficient terrazzo machine that again can rotation.

The scheme of solution task is: fix a starframe on driven axle, fix a central gear on the body horizontal bar plate, planet pin is set on the starframe, planetary gear is fixed on the planet pin with mill is coaxial.Under the effect of drive motors, through prime gear or belt transmission, the starframe that is fixed on the driven axle drives the mill revolution, and simultaneously, planetary gear is around the central gear rotation, and the rotation of drive mill.

In conjunction with the embodiments the utility model is elaborated.

Accompanying drawing is the front view of the utility model one embodiment.And be decided to be the specification digest accompanying drawing.The road wheel (2) of control stick (1) and adjustable height is fixed on the body (4) by connecting plate (3); Drive motors (5) is installed on the cover (6), and driving gear (7) and driven gear (8) are formed the prime transmission mechanism, and driving gear directly is fixed on the drive motors axle, and also available herein belt transmission replaces; Driven axle (9) is a hollow shaft, and water pipe head (10) is equipped with on its top, and its upper support is on cover (6), and the middle part is positioned at the gusset hole on the body (4), and keeps in touch, and is stable to guarantee its when rotation; Central gear (11) is fixed on the horizontal bar plate of body (4), locates same axis with driven axle (9).Fix a starframe (12) in the bottom of driven axle (9), planet pin (13) is housed on starframe, present embodiment is equipped with three, generally speaking, should be equipped with two at least, and five equilibrium is arranged; The top of each root planet pin is fixed with planetary gear (14), planetary gear and central gear (11) interlock; The lower end of each root planet pin is fixed with mill (15), is embedded with diamond or emery wheel bistrique on the mill, and establishes buffer spring (16).Backplate (17) is fixed on the body (4); Dust excluding plate (18) is fixed on the lower end of driven axle.The tight Minato of the utility model structure, in the course of the work, starframe rotates with driven axle, drives the mill revolution; Simultaneously, planetary gear rotates around central gear by the motion of starframe, planetary rotation makes mill produce rotation, then improved bistrique contact with ground with grinding process in condition of work, can improve nearly 1 times of work efficiency.

Embodiment: by the terrazzo machine that structure shown in the accompanying drawing is made, appearance and size is 1020 * 390 * 970 millimeters, weighs 180 kilograms, 3 kilowatts, 1420 rev/mins of powers of motor, and gear drive is adopted in the prime transmission; Driven axle is made with hollow thick walled steel tube, and three of planet pins are made with round steel, and five equilibrium is arranged on the starframe.Three of planetary gears, one of central gear; Three on mill, 150 millimeters of diameter phi, bistrique is made with diamond, is embedded with 6 on each mill, mill revolution: 757 rev/mins, rotation: 1270 rev/mins.The road wheel adjustment height is 50 millimeters, and body, cover, connecting plate, starframe, gear all are processed into foundry goods; 16～20 square metres/hour of productivity ratio.
