Abstract

PURPOSE: To easily and surely collect a metal piece by fixing a drum on which a cross-sectionaly C-shaped magnet is arranged on an axle, loading a wheel on the axle freely rotatably and loading a collection drum on the wheel so as to cover the magnet. CONSTITUTION: A U-shaped frame is formed by connecting respective terminals of frame members 1, 2 with a connection member 3, and the axle 4 is supported rotatably at a position opposite to the connecting position of the connection member 3. The wheels 5, 6 are supported with the axle 4 freely rotatably, and also, the drum 7 is fixed on the axle. A C-shaped magnet 8 is fixed on the drum 7 with its opening part faced in a moving direction. The collection drum 9 having a diameter larger than the outside diameter of the drum and smaller than the outside diameter of the wheel is fixed respective internal faces of the wheels 5, 6 opposite each other. A collection box 10 is provided between the connecting position of the connection member 3 of the frame members 1, 2 and an axle mounting position and also, has its upper face located at a position lower than the axle mounting position.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal piece collecting device which can collect metal pieces scattered on a floor surface easily and easily. [0002] Conventionally, when collecting metal pieces scattered on the floor surface, the following three methods have been used. The first is to manually pick up scattered metal pieces and put them in a bag. The second method is to collect scattered metal pieces in one place with a broom and put all the collected pieces into a bag. Third, the magnet in my hand was moved over the scattered metal pieces, and the drawn metal pieces were released by hand and put in a bag. [0003] In the conventional recovery method,
Since all of them are carried out manually, there is a problem that a large amount of labor and time are required for recovery in a wide range. In order to solve such a problem, the metal piece recovery device of the present invention has been devised. According to the present invention, a drum having a magnet having a C-shaped cross section is fixed to an axle, a wheel is rotatably attached to the axle, and the magnet is attached to the wheel. The above-described problems are solved, including a structure in which a collecting drum is mounted so as to cover it, and a structure in which a rectangular concave portion is formed in the axle, which is almost the same as the above-described structure except the above. According to the present invention, the magnet fixed to the drum is moved horizontally by the rolling motion of the wheels, and the magnetism of the magnet acts to collect the metal pieces scattered on the floor surface. Collection work can be performed quickly and easily. Further, in the case where the axle is formed with a rectangular recess, when the protrusion formed at one end of the lever is inserted into the recess and the lever is rotated in the direction of arrow a, the axle and the magnet are separated. When the unit moves together and the opening having the C-shaped cross section is in the state directly below, the magnetism fixed to the drum does not act and the metal piece on the floor is not attracted to enable the traveling state. An embodiment of the present invention will be described with reference to FIGS. 1, 2, 3 and 4. Two ends of the frame members 1 and 2 are connected by a connecting member 3 to form a U-shaped frame as shown in FIG. The axle 4 is rotatably supported. Wheels 5 and 6 are rotatably supported on the axle 4 and a drum 7 is fixed thereto. A C-shaped magnet 8 is fixed to the drum 7 with its opening facing the traveling direction. Wheels 5,
A collection drum 9 having a longer diameter than the outer diameter of the drum and a shorter diameter than the outer diameter of the wheel is arranged and fixed on each of the inner surfaces facing each other. The recovery box 10 is provided between the connecting position of the connecting members 3 of the frame members 1 and 2 and the axle mounting position, and the upper surface thereof is below the center of the axle mounting position. A blade 11 is fixed to the side surfaces of the frame members 1 and 2 to separate iron pieces, nails and the like from the collecting drum 9 and guide them to the collecting box 10. The connecting member 3 has a hook-shaped pulling hook 1
2 is fixed with one side thereof facing upward, a bracket 13 is fixed obliquely downward, and a wheel 14 is attached to the tip of the bracket. The drum 7 to which the magnet 8 is fixed is fixed to the axle 4 and does not rotate. However, it can be rotated by 90 degrees by inserting a lever (not shown) into the short recess formed in the axle 4. This magnet 8 is C
The mold is magnetized, and the open part is fixed on the front side during recovery, and the open part is fixed on the lower side during recovery operation by lever operation. When the apparatus is stored, the stand 13 provided with the rotating wheel 14 is grounded on the floor. Rotating wheel 1 on stand 13
Since 4 is provided, it is possible to move in this state. Also, when storing in a narrow space, the rubber cushion 15
It is also possible to store it by leaning against it. The present invention, which is constructed as described above, has an effect that only metal pieces can be collected easily and reliably on a wide range of floor surfaces.
