The present invention relates to a roll crusher, and more particularly, to a roll crusher having excellent durability and high production efficiency.

As a device for crushing waste concrete or gemstones, various devices such as roll crusher, cone crusher, bark, impact crusher, KENICA and hammer crusher are used. Among these, the cone aggregate crusher is used a lot as a fine aggregate crusher.

The cone crusher is a crushing machine using impact force and compression force, and a cone mantle head formed like an umbrella is installed on a short vertical central axis. In addition, due to the eccentric rotation of the cone mantle head, the stone is bitten down by the cone cave ball (cone cave ball) mounted on the frame is broken down, the rotation speed at this time is about 430 ~ 580rpm.

However, since the cone crusher is crushed by using a vertical striking force, the internal structure is inevitably complicated, and the vibration is largely generated, which causes a lot of trouble.

On the other hand, the conventional roll crusher is usually composed of two rolls and was not suitable for producing fine aggregates of 5 mm or less. In addition, when the roll is driven to rotate using the hydraulic pressure, a failure may occur due to the outflow of the hydraulic oil due to vibration. Moreover, since the power transmission means between the rolls is composed of gears, failures are frequently caused by gear wear due to vibration, and peripheral devices are often fatigued.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a roll crusher excellent in shock absorption capacity and low residual trouble.

In order to achieve the above object, the roll crusher according to the present invention,

And a frame, at least one pair of rolls freely rotatable on the frame, driving means for rotationally driving the rolls, and power transmission means for transmitting rotational power to other rolls paired with the rotationally driven rolls. As,

The power transmission means between the drive roll and the driven roll is characterized in that the rubber tires are installed on the rotating shaft of the drive roll and the rotating shaft of the driven roll to frictionally move with each other.

The drive means of the drive roll is preferably a chain connected between the sprocket provided on the rotating shaft of the drive roll and the drive unit sprocket of the drive unit.

The drive unit is preferably composed of a motor, a wheel connected to the motor, a rotating shaft to which the wheel is coupled, and a driving unit sprocket provided on the rotating shaft.

Another second driven roll may be coupled to the driving roll to be interlocked through a rubber tire.

It is preferable that springs are provided in the rotational shafts of the driven rolls in the lateral directions of the shafts, respectively.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 show the configuration of the roll crusher according to the present embodiment.

As shown in the drawing, the roll crusher includes a frame 700, at least one pair of rolls 100 and 100 'rotatably installed in the frame 700, and driving means for rotationally driving the roll 100. And a power transmission means for transmitting rotational power to the other rolls 100 'paired with the rolls 100 that are rotationally driven.

The lower portion of the roll crusher may be installed a conveyor 750 for transferring the crushed stone.

On the other hand, the raw stone to be crushed (or "waste concrete") is supplied to the rolls 100 and 100 'by the conveyor 913, and the raw stone of a predetermined small size (for example, 5 mm or less) through the distribution screen 933 on the way. Exits the hopper 923 and is conveyed through the conveyor 750.

Here, the power transmission means between the drive roll 100 and the driven roll 100 ', the rotation shaft 150 and the driven roll 100' of the drive roll 100 of the roll 100, 100 ' It is composed of rubber tires 200 and 200 'which are respectively provided on the rotation shaft 150' and are frictionally rotated with each other. When configured as described above, the rotational motion is made quieter by the elasticity of the rubber tire, the price is low, and problems such as conventional gear wear do not occur.

In addition, the chain 400 is connected between the sprocket 155 provided on the rotation shaft 150 of the drive roll 100 and the sprocket 455 installed on the drive unit 450, thereby sprockets ( When the 455 is driven by the motor 500, the driving roll 100 is caused to interlock. Further, the drive unit 450 is composed of a motor 500 and a wheel 600 connected to the motor 500, and the drive unit sprocket 455 on the rotating shaft 650 to which the wheel 600 is coupled. Will be combined.

Of course, it is also possible to use a pulley instead of the sprockets 155 and 455, and to use a belt instead of the chain 400.

In addition, it is also possible to drive the rotation shaft 150 of the drive roll 100 by using the motor 500 and the reduction gear train connected to the motor 500.

Accordingly, when the motor 500 rotates, the wheel 600 rotates with respect to the frame 700, the rotary shaft 650 on which the wheel 600 is installed rotates, and the sprocket 455 provided on the rotary shaft 650. ) And the sprocket 155 installed on the rotating shaft 150 of the driving roll 100 is interlocked by the chain 400. As a result, the rubber tire 200 provided on the rotary shaft 150 of the driving roll 100 is in frictional rotation in contact with the rubber tire 200 'provided on the rotary shaft 150' of the driven roll 100 '.

Through such a state of movement, the stones entered between the rolls 100 and 100 'are crushed.

In this embodiment, another second driven roll 100 "is engaged with the driving roll 100. The second driven roll 100" is disposed below the driven roll 100 '. . Thus, two breaks can be made in succession. In this case, the rotary shaft 150 "and the rubber tire 200" connected to the second driven roll 100 "must also be additionally installed.

On the other hand, on the rotating shaft 150 of the drive roll 100 and the rotating shafts 150 'and 150 "of the driven rolls 100' and 100", springs 160 'and 160 "in the transverse direction of the axes are provided. Are coupled to each other. For this purpose, the other ends of the springs 160 'and 160 "need to be located in the frame 700.

According to the present invention having the above-described configuration, since the rolling between the rolls is made by rubber tires, the wear phenomenon of the rolls and the peripheral parts can be greatly reduced as compared with the gear rolling, and the quiet operation can be expected. There is an advantage that the durability is greatly improved.

In addition, since the rotating shaft to which the roll is coupled is supported by the spring, there is also an advantage that the shock absorbing ability is excellent and there is no residual trouble.

In addition, since the transmission between the drive unit and the drive roll is made by the chain, there is less trouble compared to the hydraulic drive method and grease can be prevented from leaking.

In addition, when three or more rolls are continuously installed, there is an advantage that fine crushing up to a diameter of 5 mm or less is possible.

In addition, since sufficient crushing force can be exhibited even at a low speed operation, dust is significantly reduced compared to a conventional crusher, and there is an advantage that it can be used in all weather regardless of weather.
