[Problems to be solved by the invention]
The above-described conventional floor material peeling apparatus peels a floor located on a horizontal plane and cannot be used for peeling a floor material on the surface of a wall or ceiling in a vertical position or a high position. Moreover, since this floor material peeling apparatus is a dedicated machine including a work vehicle body, there is also a problem that the apparatus becomes expensive.
[0008]
An object of the present invention is to provide an inexpensive flooring stripping apparatus that can strip floor materials on the surfaces of walls and ceilings and solves the above problems.
[0009]
Another object of the present invention is to increase the use efficiency of the hydraulic excavator by constructing it as an attachment to be used by mounting it on a hydraulic excavator, which can be easily replaced with other types of attachments such as breakers, crushers and cutters on site.
[0010]
[Means for Solving the Problems]
In order to solve the above-described problems, the floor material peeling apparatus of the present invention is an attachment-type apparatus that is used by being attached to the tip of an arm of a hydraulic excavator. A bracket that is swingably attached to the bracket, a frame that is pivotably attached to the bracket about an axis in the vertical direction, and an actuator that is attached to the frame via an elastic member and that is driven by pressure oil sent from a hydraulic excavator. A configuration including a vibrator and a peeling blade that is vibrated in the vertical direction by a vibrator is employed.
[0011]
Since this floor material peeling device is used by being attached to the tip of an arm of a hydraulic excavator, it is possible to peel not only the floor but also the wall or ceiling floor material. In addition, since it is used by attaching to a general-purpose hydraulic excavator, a dedicated work vehicle body is not required, and the apparatus is small and inexpensive. Furthermore, since the floor material peeling device can be moved by operating the arm and boom of the hydraulic excavator, there is no need to continuously move the work vehicle body when peeling the floor material, and there is no space for moving the work vehicle body. Work is possible even in a small place. The work can also be performed by moving the work body instead of operating the arm and boom.
[0012]
In the floor material peeling apparatus, the peeling blade may be freely swingable within a certain range around a horizontal axis. Moreover, in the said floor material peeling apparatus, it may be freely rotatable around a vertical axis.
[0013]
In this way, for example, even when the floor surface is uneven or the floor surface is wavy, the peeling blade can be brought into contact with the floor correctly without adjusting the arm of the excavator each time.
[0014]
The frame is provided with guide means for regulating the displacement of the peeling blade, particularly the displacement in the front-rear direction.
[0015]
In this case, when the peeling blade is pressed against the floor or the like, the peeling blade vibrates accurately in the vertical direction, and the floor material can be efficiently peeled off. Moreover, an excessive displacement can be suppressed and the damage of an elastic member or a connection part is reduced.
[0016]
In particular, the frame has an upper wall attached to the bracket, left and right side walls projecting downward from the left and right ends of the upper wall, an exciter is disposed between the left and right side walls of the frame, and a peeling blade is provided on the exciter. The control means is attached below and includes a support member straddling between the left and right side walls of the frame below the exciter, and a guide member attached to the support member and sandwiching the peeling blade from the front and rear in cooperation with the support member. Is preferred.
[0017]
This is because the configuration of the restricting means becomes simple. Further, since the peeling blade is supported in the middle of the length by the support member and the guide member, the effective length of the peeling blade can be increased as compared with the case where the guide means is not provided. If the effective length of the peeling blade is increased, the flooring can be peeled even in a narrow space.

Further, a pin 3e protruding downward is attached near the outer periphery of the disk-shaped plate 3a. The pin 3e engages with a long hole 4e, which will be described later, and restricts rotation so that the frame 4 swings around the pin 10 within a certain range with respect to the bracket 3 when the frame 4 is attached to the bracket 3. In addition, it is preferable to arrange a vibration transmission or noise generation prevention member made of an elastic material or the like between the bracket 3 and the frame 4.
[0024]
The frame 4 attached to the bracket 3 spans a groove-shaped main body 4a that is open at the bottom when viewed from the front, a disk-like plate 4b that is attached to the upper part of the main body 4a, and lower portions of the left and right side walls of the main body 4a. And a peeling blade support member 4c provided.
[0025]
A through hole 4d into which the pin 10 is inserted is formed in the center of the disk-like plate 4b. The disk-like plate 4b has a long hole 4e extending in the circumferential direction.
[0026]
The pin 10 includes a large-diameter portion 10a bolted to the lower surface of the disk-shaped plate 4b, a medium-diameter portion 10b that passes through the through holes 3f and 4d of the disk-shaped plates 3a and 4b, and a small-diameter formed with a screw. It consists of the part 10c, and the upper end of the pin 10 is secured by a nut. The length of the medium diameter portion 10b is slightly longer than the thickness of the two disk-like plates 3a and 4b overlapped, and the frame 4 attached to the bracket 3 can swing around the pin 10.
[0027]
The front end of the pin 3e is inserted into the long hole 4e, and the frame 4 is restricted so as to be rotatable with respect to the bracket 3 only within the movable range of the pin 3e.
[0028]
An exciter 5 disposed between the left and right side walls of the frame body 4a includes two eccentric rotors 5a arranged on the left and right sides, and has a known configuration in which the hydraulic motor rotates in opposite directions to generate vertical vibrations. It is.

It has. The blade body 6c can be replaced according to the type of floor material to be peeled off.
[0030]
The guide means of the peeling blade 6 is configured as follows. A U-shaped support member 4f is bolted to the center portion of the support member 4c of the frame 4, and the blade support portion 6b of the peeling blade 6 has a gap in a space 4g formed by both the support members 4c and 4f. Is inserted. Also, sliding members 12 and 13 are interposed on the inner surface of the space 4g facing the peeling blade, so that the peeling blade 6 moves up and down smoothly in the space to prevent direct vibration transmission of the frame 4. . In order to prevent abrasion between the peeling blade 6 and the sliding members 12 and 13, it is preferable to provide a lubricant supply device that supplies a lubricant between the peeling blade 6 and the sliding members 12 and 13.
[0031]
The floor material peeling apparatus 1 having the above configuration is attached to the tip of an arm 2a of a hydraulic excavator 2 and used as follows.
[0032]
First, as shown in FIGS. 1 and 2, the arm 2a and the boom 2b are moved so that the peeling blade 6 and the floor F surface form an appropriate angle, and the cylinder 8 is expanded and contracted to the floor F to be peeled off. The inclination of the floor material peeling apparatus 1 is adjusted.
[0033]
After completion of the inclination adjustment, the tip of the peeling blade 6 is pressed against the surface of the floor F, the vibrator 2 is driven to vibrate the peeling blade 6 and the arm 2a and the boom 2b are operated to tilt the floor material peeling device 1 with respect to the floor F. The floor material Fa is peeled off by moving the floor material peeling device 1 in the forward direction while maintaining the above. At this time, the contact portion between the floor F and the peeling blade 6 is on the near side, and the operating state and the working position can be easily confirmed by the operator of the excavator 2.
[0034]
When the work place is wide and the excavator 2 can be moved, the excavator 2 may be moved. This is because the inclination of the peeling device 1 with respect to the floor can be kept constant.
[0035]
Even if the floor F to be peeled is uneven or distorted, the bracket 3 and the frame 4 rotate around the vertical axis, and the arm 2a and the bracket 3 rotate around the horizontal axis. Since the movement is allowed to a certain amount, an excessive load is not applied to the excavator 2.
[0036]
When the ceiling or wall floor material is peeled off, the arm 2a, boom 2b and hydraulic cylinder 8 are operated to adjust the floor material peeling device 1 so as to make an appropriate position or inclination with respect to the ceiling or wall. Then peel off the flooring. The peeling device 1 may be used with the mounting direction of the arm 2 and the link 14 reversed depending on the work site and contents.
[0037]
The present invention is not limited to the above embodiment, and the configuration of each part can be changed as appropriate. For example, during the peeling operation, a protrusion that contacts the floor F and keeps the inclination of the peeling device 1 with respect to the floor F constant may be provided on the bottom of the frame 4 or the vibrator 5 or the like. The protrusion may be provided integrally with the frame 4 or the like, or may be detachable.
[0038]
In the peeling device 1 of the above embodiment, the peeling blade 6 is attached to the vibrator 5 with a bolt, but the peeling blade 6 is not necessarily attached to the vibrator 5. When the peeling blade 6 is not attached to the vibrator 5, when the vibrator 5 vibrates, the peeling blade 6 is hit by the vibrator 5 and vibrates. In this case, in order to prevent the peeling blade 6 from swinging in the left-right direction, the sliding member may be a groove shape so that the left and right side walls of the sliding member are positioned on the left and right of the peeling blade. In this way, when the peeling blade 6 swings in the left-right direction, it comes into contact with the sliding member and does not swing more than a predetermined amount in the left-right direction, and the vibration is efficiently transmitted to the peeling blade 6.
