That is, the chains 61 and 62 are installed in the front sprockets 51 and 52 and the rear sprockets 53 and 54 in the form of a loop, and move in a certain orbit according to their rotation. According to this configuration, the portion between the first and second positions of the chains 61 and 62 moves along a linear path.

The chains 61 and 62 may include a first chain 61 and a second chain 62 respectively installed at both ends (ie, left and right positions) of the first and second shafts 20 and 30. For example, the first chain 61 may be installed on the left front and rear sprockets 51 and 53, and the second chain 62 may be installed on the right front and rear sprockets 52 and 54.

A plurality of scrapers 70 are installed on the chains 61 and 62 at regular intervals, and are configured to scrape and remove foreign substances in the construction waste as they move between the first and second positions. The spaced space between the plurality of scrapers 70 forms a space through which construction waste, for example, waste concrete lumps pass. The scraper 70 is in the form of a bar connecting the first chain 61 and the second chain 62, and may have a bar shape in which both sides are bent as in the present embodiment.

A plurality of mount members 80 for mounting the scraper 70 may be formed on the chains 61 and 62.

When explaining the operating state of the device for removing foreign substances in construction waste of the configuration described above, as the rotation driver 40 operates, the rotation power is transmitted to the first shaft 20 so that the front sprockets 51 and 52 rotate. Then, the first and second chains 61 and 62 installed therein are rotated. The second shaft 30 connected to the first and second chains 61 and 62 also rotates with it, so that the first and second chains 61 and 62 continue to rotate.

The first and second chains 61 and 62 move linearly between the first and second positions in which the first and second shafts 20 and 30 are respectively installed, and a plurality of scrapers 70 connected therebetween It will move in a straight line.

When the construction waste is input from the top, the construction waste is guided by the guide unit 12 and is introduced to the moving scraper 70, and foreign substances such as reinforcement, wire, and vinyl contained in the construction waste are transferred to the scraper 70 ), it is scraped and caught. Accordingly, the foreign matter moves to the edge of the foreign matter removal device while being caught by the scraper 70 and the auxiliary chain 90 and falls from the side. Collection tanks for collecting foreign substances may be disposed under both sides of the foreign substance removing device.

The construction waste from which the foreign substances are removed by this action passes through the space between the scraper 70 and the auxiliary chain 90 and falls downward, and is fed into the crusher 1 such as a double jaw crusher.

On the other hand, foreign substances such as reinforcing bars or wires are often integrated with the waste concrete mass (that is, in the form of reinforcing bars or wires protruding outside the waste concrete mass).In this case, the size of the waste concrete mass is relatively large. Reinforcing bars or wires can be moved in a form spanning two or more adjacent scrapers 70.

At this time, it is possible to move in a state where the waste concrete lump is caught between the two scrapers 70, and if this does not fall from the side of the foreign matter removal device and remains sandwiched between the scrapers 70, the chains 61 and 62 ) Or the sprocket (51, 52, 53, 54), which interferes with the rotation of the first shaft 20 or the second shaft 30 acts as a load. When such a rotational load is excessive, it may affect the performance or life of the foreign material removal device.

In order to minimize such an effect, a torque limiter that detects whether a rotation load applied to the first shaft 20 or the second shaft 30 reaches a preset value may be connected to the rotation driver 40. When the rotational load reaches a preset value, the torque limiter generates a signal, and the rotation driver 40 may operate to change the rotational driving direction according to issuance of a signal from the torque limiter. For example, while the rotation driver 40 is rotating in the forward direction, rotational load can be reduced by changing the rotational driving direction in the reverse direction according to the generation of a signal from the torque limiter, and further, rotation by reciprocating the scraper 70 It can induce the deviation of the object that generates the load.

On the other hand, an alarm is connected to the torque limiter, and an alarm can be generated when a signal from the torque limiter is generated, and when an alarm occurs, an operator can directly remove an object caught between the scraper 70.
