Description

Wavy eccentric roller crusher

The present invention relates to a crusher for breaking up larger particle sizes into smaller particle size sands.

The general stone crusher mainly comprises a plurality of pairs of rolling wheels, each of which has a different and fixed gap, that is, the gap closest to the inlet is the largest, and the gap closest to the outlet is the smallest. The other gaps from the inlet to the discharge port are sequentially from the next largest to the second, whereby when the larger particle size is thrown into the feed port, the surface of the two relatively rotating rolling wheels is utilized. The stone creates a pinch crushing action to break up the stone into smaller particle sizes suitable for construction or engineering.

However, since the stone particles are irregular in shape and vary in size and are extremely hard materials, so that when crushing is forced between the two rolling rollers of the fixed gap, the stone particles often slip off and cause crushing. The problem of different sizes of stone particles has increased the trouble of the subsequent classification of stone particles. In addition, since the gap between the two rolling wheels is fixed, the rolling wheel must be applied with a very large force when squeezing the larger particle size, except that the stone is often stuck in the rolling. Between the wheels, it takes a considerable amount of time to grind back and forth. The parts are also accelerated due to considerable force. Maintenance and maintenance are required in a short period of time, which increases the maintenance cost of the equipment.

In order to solve the aforementioned problems, the Taiwanese applicant No. M437744 proposed by the applicant in this case An eccentric roller crusher is disclosed, which comprises a first eccentric roller, a second eccentric roller and a feeding cylinder disposed adjacent to each other, and a gap between the first eccentric roller and the feeding cylinder constitutes an inlet The gap between the second eccentric roller and the feeding cylinder constitutes a discharge port, and the first eccentric roller, the second eccentric roller and the feeding cylinder form a feeding channel.

When the first eccentric roller is driven to rotate at the first rotational speed, the first cylindrical body disposed in the first eccentric roller is eccentrically rotated at the second rotational speed to cause the first eccentric roller to vibrate, thereby causing the inlet port to continuously generate The first gap of change. a second eccentric roller and a second eccentric roller are disposed in the second eccentric roller. When the second eccentric seat is driven to rotate at the third rotation speed, the second cylinder is eccentrically rotated at the fourth rotation speed to generate the second eccentric roller. Vibrating, thereby causing the discharge port to produce a constantly changing second gap, so that the larger-sized stone particles input from the inlet port are crushed and crushed into small diameters suitable for construction and engineering through the aforementioned ever-changing gap. Sand grain.

However, due to the complicated structure of the patent No. M437744, not only is maintenance difficult, but also the planes of the eccentric cylinders and the surface of the feeding cylinder are flat, so that the stones are squeezed between the smooth cylinder surfaces of the two rollers because of the lack of The space limited by the stone is easy to slip, so that the stone can not get a good crushing effect.

One of the features of the present creation is that the gap between the rollers used to crush the stone by the stone crusher is made sustainable, whereby the large or small particle size stones enter the gap between the rollers. Both can keep large and small stones in an active state without being stuck, so that the smaller particle size preferentially passes through the gap, while the larger particle size continues to grind and apply pressure on the roller. The process is crushed into smaller particle sizes and eventually becomes a building or completely through the gap between the rollers. Engineering sand.

Another feature of the present invention is that the eccentric roller wheel surface and the feeding wheel wheel surface for pressing the stone particles respectively form corresponding wave-shaped convex portions and wave concave portions, so that the stone particles are between the eccentric roller and the feeding wheel. During the rolling and grinding process, it is limited by the space of the wave concave portion and is pressed with the wave-shaped convex portion, thereby making the crushing of the stone particles easier and the crushing effect is better.

The technical means of the undulating eccentric roller crusher of the present invention comprises: an eccentric crushing wheel, which can be eccentrically arranged with at least one bearing, and a first transmission shaft is combined with the bearing, the wheel of the eccentric crushing wheel Forming a plurality of first wave convex portions and a plurality of first wave concave portions along the axial direction thereof, and the first wave convex portions and the first wave concave portions extend along a circumference of the eccentric crushing wheel; a feeding wheel a second transmission shaft is disposed at the center, the wheel surface of the feed wheel forms a plurality of second wave convex portions and a plurality of second wave concave portions along the axial direction thereof, and the second wave convex portions and the second wave concave portions are along a circumferential extension of the feed wheel; wherein the eccentric crushing wheel is adjacent to the feed wheel, and the first drive shaft and the second drive shaft are parallel to each other such that the first wave convex portion corresponds to the second wave concave portion, and the The first wave concave portion corresponds to the second wave convex portion, the upper side between the eccentric crushing wheel and the feeding wheel constitutes an inlet, and the opposite lower side constitutes a discharge port, between the eccentric crushing wheel and the feeding wheel then When the eccentric crushing wheel and the feeding wheel are driven to rotate at the same speed and in opposite directions, the eccentric crushing wheel is eccentrically operated to continuously expand and close the feeding passage, thereby squeezing the stone broken.

Preferably, the plurality of first wave convex portions disposed on the eccentric crushing wheel are disposed in phase with the first wave concave portion, and the plurality of second wave convex portions and the second wave concave portion disposed on the feeding wheel are spaced apart from each other. Configuration, so that the stone can be averaged between the eccentric crusher and the feed wheel The ground is broken.
