DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an old floor material peeling device used for replacing floor materials such as vinyl chloride tiles, linoleum, artificial turf, etc., which are bonded to a floor substrate such as concrete with an adhesive. Regarding

[0002]

2. Description of the Related Art When a floor material such as a vinyl chloride tile, a linoleum, an artificial turf, and the like, which has been conventionally stuck on a floor substrate such as a concrete floor, an old floor material must be peeled off.

As a floor material peeling device used for such a peeling operation, various types of devices have been conventionally proposed. For example, as shown in FIG. 3, the floor material peeling device disclosed in Japanese Utility Model Laid-Open No. 3-33151 has a pair of wheels 6 on the left and right rear portions of the chassis 1 and a floor material peeling blade on the front portion of the chassis. Board 41
Is provided with a blade bracket 4 attached with
A connecting rod 52 connected to an eccentric rotation shaft 51 that is rotated by a motor 53 slides the blade bracket 4 back and forth along a slide shaft 42.

In such a conventional floor material peeling apparatus,
The weight of the chassis 1 during the peeling operation is received by the floor material peeling blade plate 41 at the front end and the wheel 6 at the rear, so that
The pressing force for rubbing the floor substrate is almost constant and cannot be adjusted.

[0005] Therefore, if the pressing force for rubbing the blade plate 41 against the floor substrate is stronger than necessary, the blade plate 41 will be significantly worn, and vibration and noise will increase, adversely affecting the worker and the neighborhood. It will be. In addition, when the pressing force for rubbing the blade plate 41 against the floor substrate is insufficient, the peeling operation cannot be efficiently performed.

Further, depending on whether the floor material to be peeled off is hard or soft, and the nature of the adhesive used, the pressing material to be rubbed against the floor base of the blade plate 41 is pressed. It is necessary to properly use pressure and angle so that the strength is appropriate.

However, in the conventional floor material peeling apparatus,
It was not possible to adjust the pressing force and angle of the blade plate 41 rubbing against the floor substrate.

[0008]

SUMMARY OF THE INVENTION Therefore, a floor material according to the present invention is provided.
A first pulley provided at a rear portion of the chassis,
The chassis is installed in the middle of the chassis, and the chassis is connected via a spring.
Weight of the second pulley, the first pulley and the
And a belt consisting of a belt wrapped around the second pulley
And a blade for separating floor material provided in the front part of the chassis
Comprising a, by changing the elastic force of the spring, to adjust the pressing force against the subfloor of the flooring stripping blade plate.

A first wheel provided at a rear portion of the chassis;
And is installed in the middle of the chassis,
A second wheel for applying the weight of the chassis and a front wheel
And a blade plate for peeling the floor material,
By changing the elasticity, the floor of the above-mentioned floor material peeling blade plate
Adjust the pressing force against the substrate .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in the side view of FIG. 1, a floor material peeling apparatus of the present invention comprises a pair of first pulleys on the left and right of a rear portion of a chassis 1.
21 is provided, and a second pulley 22 is also provided at an intermediate portion of the chassis 1. A rubber belt 23 is stretched between the pulleys 21 and 22 to form a rubber crawler 2.

The rotating shaft 25 of the first pulley 21 is inserted into a bearing provided on the chassis 1 so that it can be driven by a motor 27 to be self-propelled, and the rotating shaft of the second pulley 22.
26 bearings are formed at one end of the rod 24 and this rod
At the other end of 24, a bearing for inserting the rotating shaft of the first pulley 21 is provided, and the bearing of the second pulley 22 is
It is pivotally supported so that it can rotate up and down.

A spring 12 is interposed between the bearing of the second pulley 22 and a fulcrum 11 provided on the chassis 1,
The bearing of the rotating shaft 26 of the second pulley 22 is pressed downward to apply a part of the weight of the chassis 1.

The chassis 1 is provided with an eccentric rotating shaft 51 rotated by a motor 53 via a belt 54. The eccentric rotating shaft 51 and the blade bracket 4 are connected to a connecting rod.
Connected by 52 to convert rotational movement into horizontal sliding.

At the front end of the chassis 1, there is provided a frame 3 which can rotate around a shaft 13 provided on the chassis 1.
, A slide shaft support portion 31 is fixed, and the blade bracket 4 is slidably supported back and forth by a slide shaft 42 inserted through the slide shaft support portion 31. The floor material peeling blade 41 is attached.

A projection having a female screw 32 is provided on the upper portion of the frame 3.
A female screw 33 is screwed with a male screw rod 16 which is rotated by a crank 17 via a universal joint 14. The male screw rod 16 is held at the upper part of the chassis 1 by the thrust bearing 15.

A push handle 10 is provided at the rear end of the chassis 1.

Next, the operation of the floor material peeling apparatus thus configured will be described. The hand push handle 10 is pushed down, the floor plate stripping blade 41 is lifted up, and the motor 27 drives the rubber crawler 2 including the first pulley 21, the second pulley 22 and the rubber belt 23 to carry out the stripping work. Self-propelled to the site to perform.

At the site where the peeling work is performed, the motor 53
Is driven, the eccentric rotation shaft 51 is rotated via the belt 54, and the eccentric rotation causes the blade bracket 4 to horizontally slide back and forth via the connecting rod 52.

The floor material can be peeled by horizontally sliding the floor material peeling blade plate 41 attached to the blade bracket 4 back and forth on the floor substrate.

At this time, by appropriately adjusting the elasticity of the spring 12 for pressing the bearing of the second pulley 22 downward, the pressing force for rubbing the blade plate 41 against the floor substrate can be set to an optimum value. it can.

Further, by operating the crank 17 to rotate the male screw rod 16 and moving the projection 33 of the frame 3 back and forth, the frame 3 is tilted, and the angle formed by the blade plate 41 and the floor base is adjusted. Can be adjusted.

(Other Embodiments) In the embodiment described above, the first pulley 21, the second pulley 22,
The rubber crawler 2 composed of the belt 23 is used to set the pressing force of the floor material separating blade 41 against the floor substrate to an optimum value, but instead of the rubber crawler 2, the rear part of the chassis and the middle part Even if two pairs of wheels are provided on the left and right of the section and the load applied to the wheel in the middle section is changed by the spring, the same effect can be obtained.

[0023]

As is clear from the description based on the above embodiments, according to the floor material peeling apparatus of the present invention, the floor base of the blade plate 41 is matched to the floor material to be peeled and the adhesive used. Since the pressing force against and the angle formed by the blade plate 41 and the floor base can be set to optimum values, the efficiency of the peeling work can be improved and the wear of the floor material peeling blade plate 41 can be reduced.
