Abstract

The utility model relates to a belt pulley type terrazzo machine with a planet grinding disc. In the utility model, a star shaped frame is arranged on a driven shaft; a center belt pulley is fixed on the transverse bar plate; a planet belt pulley shaft is arranged on the star shaped frame; a planet belt pulley is arranged on the planet belt pulley shaft; the grinding disc is fixed with the planet belt pulley. The grinding disc can do revolution around the driven shaft, simultaneously, the grinding disc can generate autorotation through the rotation of the planet belt pulley shaft at the time of working. The working conditions of the process of grinding and the contact between a grinding head and the earth surface can be improved and the work efficiency is improved more than two times.

Description

Belt-driven terrazzo grinder with planet grinding head

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 pulley on body horizontal bar plate, the planet Pulley shaft is set on starframe, planet belt pulley and mill are coaxial to be fixed on the planet Pulley shaft.Under the effect of drive motors, through prime belt or gear drive, the starframe that is fixed on the driven axle drives the mill revolution; Simultaneously, the planet belt pulley rotates by belt, makes to produce rotation again with the co-axially fixed mill of planet belt pulley.

In conjunction with the embodiments the utility model is elaborated:

Accompanying drawing is the front view of the utility model one embodiment.And be appointed as 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 drive pulley (7) and negative pulley wheel (8) are formed the prime transmission mechanism, and drive pulley (7) directly is fixed on the drive motors axle; Also available herein gear drive 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 horizontal bar plate hole on the body (4), and keeps in touch, and is stable to guarantee its when rotation; Fix a starframe (12) on driven axle (9), central pulley (11) is fixed on the horizontal bar plate of body (4), locates same axis with driven axle (9); Planet Pulley shaft (13) is housed on starframe, and present embodiment is three, and the Pulley shaft that is contained on the starframe is two at least, and five equilibrium is arranged.Pulley shaft top is fixed with planet belt pulley (14) corresponding belt stretcher (18) is set on starframe.The mill (15) that is embedded with diamond or emery wheel bistrique is coaxial fixing with the planet belt pulley, establishes buffer spring (16) on the mill.Backplate (17) is fixed on the body (4).The tight Minato of the utility model structure, in the course of the work, starframe rotates with driven axle, drives the mill revolution; Simultaneously, the planet belt pulley rotates by belt, makes the mill rotation.Improved then that bistrique contacts with ground and grinding process in condition of work, can improve work efficiency more than 1 times.

Embodiment: by the terrazzo machine that structure shown in the accompanying drawing is made, appearance and size is 1020 * 436 * 1300 millimeters, weighs 170 kilograms, 3 kilowatts of powers of motor, and 1420 rev/mins, belt transmission is adopted in the prime transmission, and drive pulley directly is fixed on the drive motors axle; Three of planet belt pulleys, three of planet Pulley shafts, five equilibrium is arranged on the starframe, one of central pulley, three on mill, diameter are 180 millimeters of φ, be embedded with 6 of diamond grinding heads on each mill, mill revolution: 1030 rev/mins of 946 rev/mins, rotation, the road wheel adjustment height is 50 millimeters.Driven axle is made with hollow thick walled steel tube, and the planet Pulley shaft is made with round steel, and body, cover, connecting plate, starframe, belt pulley cylinder iron part process.All support with bearing the rotation contact position of axle.Productivity ratio is 23～28 square metres/hour.

Claims (3)

1, the wheeled planetary mills dish of a kind of belt terrazzo machine, form by control stick, road wheel, connecting plate, body, cover, drive motors, belt or gear drive, driven axle, the mill and the backplate that are embedded with diamond or emery wheel bistrique, feature of the present utility model is: be fixed with starframe [12] on driven axle [9], on body horizontal bar plate, be fixed with central pulley [11], planet Pulley shaft [13] and belt stretcher [18] are housed on starframe, planet belt pulley [14] is housed on the planet Pulley shaft.

2, terrazzo machine according to claim 1 is characterized in that being equipped with at least on the starframe (12) two planet Pulley shafts (13).
