Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for supplying metal scrap to a crusher.

(Prior Art) As a method of supplying metal scrap such as cutting scraps to a rotary crusher that has been conventionally crushed by a rotor equipped with several hammers, a feeding roller is provided near the supply port of the hopper. There is one in which a metal scrap is sent into a crushing chamber of a crusher by a roller.

(Problems to be solved by the invention) However, in the above-mentioned conventional technique, since the metal scrap supplied into the hopper is fed into the crusher main body only by the feeding roller, the cutting waste of the viscous material is eliminated. When processing scraps, etc., these scraps become entangled with each other and form a lump, which easily causes a hanging phenomenon in the hopper, making it impossible to supply metal scrap to the crushing chamber, causing a drop in the operating rate. ing. Further, even when the scrap reaches the supply port, the entangled scrap is pulled into the crushing chamber as a lump, causing overload and increasing the load fluctuation rate. For this reason, power consumption increases, which causes a high cost of scrap processing.

The object of the present invention is to constantly supply a fixed amount of metal scrap to the crusher body, thereby improving the operation rate of the crusher, reducing power consumption, stabilizing load fluctuations, and processing metal scrap. It is to reduce costs.

(Means for Solving the Problem) A first feature of the present invention is that a supply plate of a hopper has a slide plate on one side and a push plate on the other side so as to form a V shape. The slide board has a slider slidable with respect to the hopper, and the pushing board has a movable sliding portion provided with a feeding roller at its tip, and the slide board and the pushing board are provided. Is to adjust the amount of metal scrap fed into the supply port by the forward / backward movement.

A second feature is that a metal scrap pressing gate is slidably attached to the hopper above the pushing board.

(Operation) The metal scrap supplied into the hopper moves to the vicinity of the supply port by natural fall and is fed into the crusher main body by a fixed amount by the rotating feeding roller. If the metal scraps are entangled with each other to form a lump and the metal scrap cannot be fed only by the feeding roller, the slide plate and the pushing plate move alternately to push the metal scrap from the supply port, and It is sent to the crusher body by the dengue roller. When the metal scrap is suspended in the hopper, the gate operates to cover the metal scrap in the hopper and presses the metal scrap toward the supply port. Operates and sends metal scrap to the crusher body.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

The crusher main body 1 is provided with an inclined container-shaped hopper 2, and the hopper has an outer lower surface supported by a column 3. At the lower supply port 2c of the hopper 2, a slide board 4 is formed on one side and a pushing board 5 is formed on the opposite side so as to form a V shape.
Is provided, and the supply amount of the metal scrap S is adjusted by the forward / backward movement of the slide plate and the push-in plate.

Explaining a specific configuration of the slide board 4, an outer side plate 2b is provided along the side plate 2a outside one side plate (left side) of the hopper 2. A slider 4a is housed between the two side plates 2a and 2b so as to be slidable in the vertical direction along the both side plates. The slider 4a can be moved forward and backward by driving a hydraulic cylinder 4b having a long stroke of a piston rod attached to the lower side of the side plate 2a of the hopper 2.

The pushing board 5 is provided with a sliding portion 5a which is slidable vertically along the mounting hole 2d. A feeding roller 5b is attached to the front end of the sliding portion 5a, and a geared motor 5c for driving the feeding roller is attached to the rear end of the sliding portion 5a. The sliding portion 5a can be moved back and forth by driving a drive cylinder 5d attached to the outside of the outer plate of the hopper 2.

A gate 6 is arranged on the outer plate above the pushing board 5.
The gate 6 is swingable by driving a hydraulic cylinder 6b attached to the outside of the hopper 2 around a pin 6a fixed to an outer plate, and normally one side surface of the hopper 2 is closed (solid line shown). State). The gate 6 acts to forcibly press the lumped scrap S in the hopper 2 against the supply port 2c.

The supply port 2c of the hopper 2 communicates with the crushing chamber 1a of the crusher main body 1, and in this crushing chamber 1a, a roller 8 rotatably supporting several hammers 7 is rotatably supported. A receiving blade 1b is provided below the entrance of the crushing chamber, and a great bar 9 for discharging the crushed scrap S is arranged around the lower half of the crushing chamber. The rotor 8 can be rotationally driven via a V-belt 11 by a motor 10 attached to the outside of the crusher body 1. 12 is a damper.

Next, the operation will be described.

In order to adjust the amount of scrap S supplied from the supply port 2c in advance, the position of the slider 4b of the slide board 4 is set to the cylinder 4a.
And the position of the pushing board 5 is set appropriately. First, when metal scrap S is fed into the hopper 2 from above the hopper 2 by the lifting magnet M, this scrap is moved to the side plate inside the hopper.
It slides down along 2a and reaches the supply port 2c. Here, the scrap S is fed into the crushing chamber 1a by an appropriate amount by the rotation of the feeding roller 5b. When the scraps S are entangled with each other in the hopper 2 and cannot be fed by the feeding roller 5b, the slide board 4 that senses this operates to lower the slider 4a, and the scraps S stopped midway To near the supply port 2c. At this time, the pushing board 5 is appropriately moved up and down to adjust the size of the supply port 2c, and the scrap is pushed in.

When the scrap S is suspended in the hopper 2 in the middle of the hopper 2, the cylinder 6b is actuated to move the gate 6 to cover the hopper, and the stagnant scrap is pressed down. After the slide board 4 makes it possible to push it, the push board 5 sends it into the crushing chamber 1a. In this way, the scrap S is sent into the crushing chamber 1a by an appropriate amount, crushed therein, and discharged outside the gap of the great bar 9 and the damper 12.

(Effect of the Invention) As described above, according to the present invention, the supply amount of metal scrap to the crusher main body is increased and decreased by the forward and backward movements of the V-shaped slide plate and the pushing plate at the supply port of the hopper. A proper amount can be used, and since the pushing plate is provided with a floating roller, the metal scrap can be efficiently pushed into the crusher body. Further, overload due to excessive supply of metal scrap will not occur, which contributes to cost reduction due to reduction in power consumption accompanying a reduction in load variation rate. Also, by providing a gate, even if scrap is suspended in the hopper, it can be forcibly pushed toward the supply port, without interrupting operation and improving the operating rate. .
