  By the way, according to the law requiring the separation of industrial waste, it becomes necessary to strictly separate the waste treatment materials discharged when the building is renovated or demolished for each material. However, in the conventional floor material peeling device, the scraper 51A only vibrates and cannot move in the linear direction. Therefore, when the scraper 51 is provided at the tip of the arm 52A of the work machine 52 and operates, the scraper is against the peeling surface 53 such as a wall surface. As a result of drawing a circular orbit, there is a drawback in that the base material is shaved together with the building material. For this reason, after peeling off, the worker has to perform the work of manually peeling off the base material from the building material and separating it, resulting in poor work efficiency and increased human rights costs. Furthermore, in order to move the scraper of the conventional floor material peeling apparatus horizontally, a skill required for the operator of the work machine 52 is required, and there is a drawback that the work efficiency cannot be increased.

  The present invention has been made in view of the above-described drawbacks of the prior art, and can easily and efficiently peel off building materials such as wall materials and carpets from the base material in the work of remodeling or dismantling the building. Therefore, an object of the present invention is to provide a scraper device for stripping building materials that can reduce various costs because post-processing work for separating the base material and the building materials can be made unnecessary.

  The means of the present invention configured to solve the above-described problems includes a base that is detachably provided at the end of an arm of a work machine, a movable support that is mounted on the base, protrudes from the base, and can advance and retreat in a linear direction. A support driving means provided on the base for moving the movable support forward and backward in a linear direction; a scraper support pivotally supported on the front end side of the movable support and swingable in the front-rear direction; and the scraper support A scraper provided on the body, and a vibration means mounted on the movable support and configured to vibrate the scraper in the front-rear direction via the scraper support.

  The scraper may be attached to the scraper support by reversing the upper and lower sides.

Since the present invention is configured as described in detail above, the following effects can be obtained.
(1) Since the scraper can advance and retreat in the linear direction regardless of the arm tip of the work machine drawing a circular orbit, the building material can be easily and reliably peeled off from the base material. Therefore, it is also suitable to use for work which does not want to damage the base material as in the case of renovating a building.
(2) Since only the building material can be reliably peeled from the base material, the post-treatment work for separating the base material and the building material after peeling can be eliminated.
(3) Since the scraper can be attached to the scraper support by reversing the top and bottom, if the scraper blade is worn or damaged by the work, it can be used by converting the top and bottom at the site. it can.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2, reference numeral 1 denotes a base that is detachably attached to the tip of an arm A of a working machine such as a hydraulic excavator by pin connection.

By comprising the plate 2E and the bracket 2F projecting from the partition plate 2E, the base 1 has a box shape with an opening 1A on the front side and a housing portion 1B in the rear, and the top surface of the top plate 2D. A pair of mounting brackets 3, 3 for connecting with the arm A are projected.

  Reference numeral 4 denotes a movable support member that is inserted into the base body 1 so as to be swingable in the front-rear direction in a state of protruding from the opening 1A. The movable support member 4 includes a movable bottom plate 4A that is in contact with the bottom plate 2A of the housing part 2, and The front and rear sides of the pair of movable side plates 4B and 4B and the movable top plate 4C are formed in a rectangular tube shape, and a support bracket 4D is provided at the front end of the lower surface of the movable top plate 4C.

  Reference numeral 5 denotes a hydraulic cylinder as a support driving means for moving the movable support 4 forward and backward in the direction of the arrow B. The hydraulic cylinder 5 has the rear end of the cylinder 5A as a partition plate 2E of the base body 1. The piston rod 5B is pivotally supported via a bracket 2F, and the tip of the piston rod 5B is connected to the support bracket 4D by a connecting pin 6. Then, by operating the hydraulic cylinder 5 with the hydraulic oil supplied from the hydraulic excavator, the movable support 4 advances and retreats in the linear direction while protruding from the base 2.

  7 is a scraper support that is positioned in front of the movable support 4 and is pivotally supported on the support bracket 4D by the connecting pin 6 and whose lower end side can swing in the front-rear direction. The scraper support 7 is made of a horizontally long steel plate, A bracket 7A for pivotally supporting the support bracket 4D protrudes from the center upper side of the rear surface. A lower plate 8A is bent forward on the front surface of the scraper support 7, and a mounting plate 8 having a pair of bolt holes drilled apart in the longitudinal direction is fixed. Note that the scraper support 7 and the mounting plate 8 may be integrally formed.
