Abstract

The utility model relates to a floor grinding machine, in particular to a multifunctional floor grinding machine, which is characterized in that the lower part of a vertical drive shaft and a disc are provided with a locating rod, the rod shaft is provided with a location sleeve and a restoring damper spring, and the outside of the disc is provided with three screw-shaped through holes. A big cylinder screw bolt whose one end is unthreaded is fixed in the hole, three through holes whose diameters are larger than the diameter of the big cylinder are arranged at the screw-shaped through hole positions of a corresponding grinding disc. A big cylinder body at the lower part of the screw bolt can be inserted into the hole, and a plurality of replaceable grinding discs are arranged out of the front surface of the grinding disc. The utility model has the advantages that with changing the grinding disc, the utility model can accomplish the floor grinding, burnishing and scaling operations, the grinding disc can automatically adjust the best working state of the grinding disc according to the difference flatness of the grinded surface in the operation. The utility model can also be matched with a vacuum cleaner in order to reduce the dust pollution.

Description

A kind of Multifunctional mill diji

Technical field

The utility model relates to floor grinding machine, particularly relates to a kind of Multifunctional mill diji, is applicable to that the cement flooring polishes, polishes and eliminated rust by flour milling.

Background technology

Existing floor grinding machine function singleness, promptly the abrasive material on the mill is difficult for changing, and in mill ground process, the mill self-regulating angle is little, incompatible polishing to different Pingdus ground, when mill ground, dust from flying is harmful to health, and applicability is relatively poor.

The utility model content

The purpose of this utility model is at the above-mentioned defective that exists in the prior art, and a kind of Multifunctional mill diji is provided.

The technical solution of the utility model is to comprise body, land wheel, handgrip, power supply, motor, drive pulley, negative pulley wheel and belt thereof, the vertical drive shaft that connects negative pulley wheel, the mill that connects this, it is characterized in that: its vertical drive shaft bottom connects a disk, location bearing is equipped with in its top and the bottom, axle bottom and disc centre have a blind hole, a positioning rod is housed in the hole, there is convex shoulder the bar lower end, be with location limit journey sleeve on the bar, bar is limit on the journey sleeve with the location and is with the buffer spring that resets, there are three tapped through holes that equidistantly distribute in the disk outside, fixing a bolt by nut in the hole, its bolt bottom is threadless large cylinder; At the position of its mill corresponding to above-mentioned three tapped through holes, the through hole of three diameters greater than bolt bottom large cylinder diameter arranged, be inserted with the no screw thread large cylinder of above-mentioned bolt bottom in this through hole, it can be in this through hole, along with mill to the polishing on different Pingdus ground and collide hole wall, force mill to be adjusted in real time and beat angle, reach optimum Working, there be 6-10 equidistant abrasive disc that through hole is installed in the mill outside, the abrasive disc connecting axle is housed in each hole, convex shoulder convex shoulder wear washer and removable abrasive disc down is housed in the axle bottom, the face of trying to get to the heart of a matter is fixed with abrasive material, as emery cake and sand paper, during each abrasive material mill ground, also can change the abrasive disc attitude, because abrasive disc is along with the polishing to different Pingdus ground, can adjust grinding angle with contacting of its packing ring convex shoulder face by the abrasive disc back side, the height of convex shoulder provides condition for regulating the abrasive disc grinding angle.

Dust pollution when grinding ground in order to reduce is equipped with dustproof skirt and is provided with an interface that can dock with dust collector suction pipe on body in the body lower edge, be convenient to and the supporting use of dust catcher.

The beneficial effects of the utility model are finish mill ground, the operation of polishing and derust, and in operation, mill can be adjusted mill and be optimum Working automatically along with by the different Pingdus of flour milling by changing abrasive disc.Can also with the supporting use of dust catcher, reduce dust pollution.

Description of drawings

Fig. 1 is structural representation of the present utility model and Figure of abstract.

The specific embodiment

Referring to Fig. 1 structure of the present utility model as can be known: comprise body rack, land wheel, handgrip, power supply, motor, drive pulley, negative pulley wheel and belt thereof, the vertical drive shaft that connects negative pulley wheel, the mill that is connecting this axle, it is characterized in that: its vertical drive shaft 1 bottom connects a disk 2, location bearing 3 is equipped with in the top and the bottom of axle, axle bottom and disc centre have a blind hole 4, a positioning rod 5 is housed in the hole, there is convex shoulder 6 (bar carefully head-up inserts from disk 2 bottom center holes) the bar lower end, be with location limit journey sleeve 7 on the bar 5, be with the buffer spring 8 that resets on bar and the positioning tube, there are three tapped through holes 9 that equidistantly distribute in the disk outside, fixing a bolt 10 by nut in the hole, its bolt bottom is threadless large cylinder 11, at the position of its mill corresponding to above-mentioned three tapped through holes 9, the through hole 12 of three diameters greater than bolt bottom large cylinder 11 diameters arranged, adorning in this through hole can along with mill to the polishing on different Pingdus ground and collide hole wall, force mill to adjust the bolt bottom of beating angle in real time and do not have screw thread large cylinder 11, so that mill reaches optimum Working, the outside has 6-8 equidistant abrasive disc that through hole 14 is installed on mill 13, the connecting axle 15 of abrasive disc is housed in the hole, convex shoulder convex shoulder wear washer 16 and abrasive disc 17 down is housed in this bottom, the face of trying to get to the heart of a matter is fixed with emery cake 18, during each abrasive material mill ground, also can change the abrasive disc attitude, adjust grinding angle and be optimum Working, because the abrasive disc back side contacts with packing ring convex shoulder face face, the height of convex shoulder provides condition for regulating the abrasive disc grinding angle.

When working, reduce dust pollution, reduce infringement, dustproof skirt 20 is housed in body 19 lower edges and on body, is provided with an interface 21 that can dock with the dust catcher sweep-up pipe to health for the utility model.

In order to regulate the mill center of gravity, to increase or to reduce the polishing dynamics, the position of mounting hole of its land wheel 22 wheel shafts can move (not shown) forward or backward.
