Description

Improved structure of 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 particles create a sandwich crushing action to break the stone into a smaller particle size suitable for construction or engineering purposes.

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, Taiwan Patent No. 101204239 provides a An eccentric roller crusher comprising a first eccentric roller disposed adjacent to each other, a second eccentric roller and a feeding cylinder, wherein a gap between the first eccentric roller and the feeding cylinder forms an inlet opening, 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; the first eccentric seat in the structure is at the first rotation speed Rotating, causing the first cylinder to rotate eccentrically at a second rotational speed and generating vibration, thereby causing the inlet port to generate a constantly changing first gap; and when the second eccentric seat is rotated at the third rotational speed, the second cylinder is The fourth rotation speed is eccentrically rotated and generates vibration, so that the discharge port produces a constantly changing second gap, so that the larger particle size stone injected from the inlet port is crushed and formed into a suitable shape through the aforementioned constant gap. Small particle size sand for construction and engineering.

The above-mentioned Patent No. 101204239 utilizes two eccentric rollers to cooperate with one feeding cylinder to crush the stones. Therefore, two power systems are required to drive the two eccentric rollers, and the entire transmission mechanism is complicated and the manufacturing cost is high.

The purpose of this creation is to solve the problem that the conventional crusher uses two eccentric rollers to press a feeding cylinder to squeeze the stone particles, and must be equipped with two power systems to drive the two eccentric rollers, so that the mechanism is complicated and the manufacturing cost is low. Higher problem.

One of the features of the present invention is that an eccentric roller is operated with a feeding cylinder to continuously change the gap between the eccentric roller and the feeding cylinder to crush and crush the stone, thereby regardless of the large particle size or When the small-sized stone particles enter the gap between the rollers, the large and small stones are also kept in an active state without being stuck, so that the smaller-sized stones preferentially pass through the gap, and the larger particles are larger. The stone particles of the diameter are crushed into smaller particle sizes during the continuous grinding and pressure application of the drum, and finally become the construction or engineering sand through the gap between the rollers.

Based on this, the technical means of the present invention comprises an eccentric roller and a feeding cylinder, wherein the eccentric roller has a cylinder, at least one eccentric wheel extending through the inner diameter of the cylinder, the outer diameter of the eccentric wheel and the cylinder Between the inner diameters of the bodies, at least one bearing is disposed; the feeding cylinder is disposed at a center of the center adjacent to the eccentric roller, so that a gap between the eccentric roller and the feeding cylinder forms a feeding passage, and respectively on the upper and lower sides of the feeding passage An inlet port and a discharge port are formed, and when the eccentric roller rotates, a constantly changing gap is generated between the cylinder and the feeding cylinder.

When the eccentric roller is matched with a feeding cylinder, the virtual connection between the center of the eccentric roller and the center of the feeding cylinder may be a horizontal line.

When the eccentric roller is engaged with a feeding cylinder, the virtual connection between the center of the eccentric roller and the center of the feeding cylinder may form an angle with a virtual horizontal line; and based on the virtual horizontal line, the The eccentric drum is higher than the feed cylinder or the feed cylinder is higher than the eccentric cylinder.

Another feature of the present invention is that an eccentric roller can be operated with two feeding cylinders, so that an inlet port, a feeding channel and a discharging port are formed between the eccentric roller and the two feeding cylinders to crush the stone particles.

Based on this, another technical means of the present invention includes an eccentric roller and two feeding cylinders, wherein the eccentric roller has a cylinder and at least one eccentric wheel disposed inside the inner diameter of the cylinder, and the eccentric wheel is externally Between the diameter and the inner diameter of the cylinder, at least one bearing is disposed; the two feeding cylinders are respectively disposed at a center of the center adjacent to the eccentric roller, so that a gap between the eccentric roller and one of the feeding cylinders constitutes an inlet port, The gap between the eccentric roller and the other feeding cylinder constitutes a discharge port, and the eccentric roller and the two feeding cylinders form a feeding passage. When the eccentric roller rotates, the cylinder body and the two feeding cylinders simultaneously generate continuously The gap between changes.

When the eccentric roller is matched with the two feeding cylinders, the center of the eccentric roller forms an angle with the virtual connecting line of the center of the two feeding cylinders, and the two feeding cylinders are respectively located above and below a virtual horizontal line.

In order to achieve a better crushing effect of the stone, the eccentricity of the eccentric roller of the present invention is 6 mm, so that the gap varies from 2 mm to 14 mm.

In order to make the eccentric roller of this creation obtain a good vibration impact effect, the creation is to make the eccentric roller generate a rotation speed of 400~500 rpm, so that the cylinder body generates a rotation speed of 10-15 rpm and generates vibration at the same time.

With the improved eccentric roller crusher of the present invention, the driving mechanism of the eccentric roller can be simplified, thereby reducing the manufacturing cost of the crusher, and thus creating a novelty and progress.
