Abstract

The utility model relates to a self-propelled hydrostone-flat grinder used for grinding and processing the quartzose concrete floor, which can be controlled by the operator using a switch box holding in hands at the position far away from the machine. The hydrostone-flat grinder can do high-speed grinding because a grinding head is adopted with the diamond material. The grinding depth can be adjusted following the changes of the distance from the earth surface because a pressing spring is arranged on a grinding disc, which can improve the flatness of the earth surface grinding. A machine cover can make the electric motor work under the sealing status. Hence, the self-propelled hydrostone-flat grinder is an earth surface construction machine with the advantages of fast grinding, good labour condition, high construction quality and safe utilization, which can be widely popularized.

Description

Machine for polishing concrete floor

The utility model relates to and a kind ofly with grinding method the equipment of Surface Machining is carried out in quartzy cement floor, belongs to ground construction machinery.

Known levigator is a hand propelled, and two road wheels are arranged, and the bistrique material is a silicon carbide grinding wheel, be installed on the mill, pass through the transmission device driven rotary by motor, during grinding, the flushometer bath was both cooled off bistrique, again the mud after the grinding was washed.Because slime water is splash under the effect of rotation bistrique, there is not sealing between motor and the bistrique, spatter with water easily and cause electric leakage, self-sharpening can be poor again during the silicon carbide grinding wheel grinding, and therefore, this levigator condition of labor is poor, work efficiency is low, use dangerously, and manpower carries out grinding, also cannot say for sure to demonstrate,prove the planeness of ground grinding.

Task of the present utility model is that a kind of grinding speed of design is fast, and the high and self-propelled levigator safe in utilization of grinding equalizing degree improves operative employee's condition of labor, improves construction quality.

This manual provides the following drawings:

Fig. 1: the main sectional view of levigator;

Fig. 2: the diagrammatic top view of levigator;

Diagram: 1, frame; 2, motor; 3, gear-box; 4, the spring of exerting pressure; 5, mill; 6, bistrique; 7, directive wheel; 8, driving wheel; 9, motor; 10, belt transmission; 11, worm and gear transmission; 12, click transmission; 13, valve; 14, faucet; 15,16,17, switch; 18, hood; 19, lever; 20, chute; 21, key; 22, handgrip; 23, feed pipe.

Accompanying drawing has been described a kind of embodiment of the present utility model, sets forth content of the present utility model below in conjunction with accompanying drawing:

Frame (1) goes up installs grinding attachment, running gear and flushometer, grinding attachment is by motor (2), transmission mechanism, mill (5) and bistrique (6) are formed, the transmission mechanism that present embodiment adopts is gear drive, four gears are contained in the gear-box (3), motor (2) drives the two groups of bistriques (6) that are installed in respectively on two mills (5) by gear drive and does rotation in opposite directions, mill (5) has the spring of exerting pressure (4) and by lever (9), the lift that chute (20) and key (21) constitute, running gear comprises two driving wheels (8), a directive wheel (7) and two cover drive units, every cover drive unit drives a driving wheel (8) walking, and this drive unit is made up of motor (9) and deceleration transmission system.The operation of motor (2,9) is controlled by switch (15,16,17).Flushometer is made of faucet (14), valve (13) and feed pipe (23).This levigator also is equipped with handgrip (22), and after lift was mentioned mill (5), handgrip (22) can be carried out transportation for manpower and use.

Above-mentioned deceleration transmission system is made up of belt transmission (10), worm and gear transmission (11) and click transmission (12).

Above-mentioned switch (15,16,17) is got in touch with levigator by cable, can make the operation of operative employee at dried up grinding machine control levigator in place far away like this.

Select for use diamond to be installed on the mill (5) by pressing plate as bistrique material, one group of 12 diamond chip.

Hood (18) is set, strengthens the sealing of complete machine.

Levigator with above all technical characteristic has promptly constituted most preferred embodiment of the present utility model.

Use this self-propelled levigator, the operative employee can move control at the position hand held switch box of disembarking far away, has both alleviated workman's labour intensity, can prevent that again the slime water of splash spatters body, carries out safety operation, has improved working condition. The diamond grinding head self-sharpening is good, can carry out high-speed grinding, and according to test, grinding speed improves more than five times than general levigator. The spring of exerting pressure can make mill fluctuate with state of ground, thereby grinding depth is adjusted, and the flatness of ground grinding is also just higher. Hood places motor under the sealing condition and works, and the electric leakage possibility is little, and the complete machine flushing is convenient. Therefore, this self-propelled levigator is that a kind of grinding speed is fast, and working condition is good, and the construction quality height uses safety, the ground construction machinery that can extensively promote the use of.
