Description

Crusher drive

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, Taiwan Patent No. 101204239 provides an eccentric roller crusher including a first eccentric roller disposed at a position adjacent to each other, and a second The eccentric roller and a feeding cylinder, the 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 discharging port, the first eccentric roller, the first Between the two eccentric rollers and the feeding cylinder, a feeding passage is formed; when the first eccentric seat in the structure rotates at the first rotation speed, the first cylinder rotates eccentrically at the second rotation speed and generates vibration, thereby making the inlet port Producing a constantly changing first gap; when the second eccentric seat is rotated at the third rotation speed, the second cylinder is eccentrically rotated at a fourth rotation speed and generates vibration, thereby causing the discharge port to generate a constantly changing second gap. The larger-sized stone particles input from the inlet port are crushed and crushed into small-sized sand suitable for construction and engineering through the aforementioned ever-changing gap.

The first eccentric roller, the second eccentric roller and the feeding cylinder of the above-mentioned Patent No. 101204239 are respectively driven by independent power, and therefore, the entire transmission mechanism is complicated, and the relative rotation speed between the eccentric roller and the feeding cylinder is relatively impossible. Control is in the most ideal state, thus reducing the efficiency of crushed stone.

The purpose of this creation is to solve the problem that the conventional crusher uses a two rolling wheel with a fixed gap to squeeze the stone. When a large particle size is encountered, the rolling wheel must be applied very large. The force, in addition to the easy to have the stone particles stuck between the rolling wheels, has to take a considerable amount of time to grind back and forth, the machine parts also accelerate the wear due to the considerable force, which increases the maintenance cost of the machinery and equipment. .

Another purpose of this creation is to solve the problem that the transmission mechanism of Taiwan Patent No. 101204239 is complicated, and the relative rotational speed between the eccentric roller and the feeding cylinder cannot be controlled in an optimal state, so that the crushed stone cannot be further improved. The problem of efficiency.

One of the features of this creation is the use of a crusher between the rollers that squeeze the stone. The gap is set to be sustainable, whereby both large and small particle sizes can keep the large and small stones in an active state without getting stuck, regardless of whether the large or small particle size enters the gap between the rollers. The smaller particle size of the stone preferentially passes through the gap, while the larger particle size is crushed into a smaller particle size during the continuous grinding and pressure application of the drum, and finally becomes a building or engineering through the gap between the rollers. sand.

Another feature of the creation is that the drum is simultaneously vibrated and impacted during the rolling and grinding process, thereby making the crushing of the stone easier, and the broken stone does not cause a jam phenomenon, and is easier. fall.

Another feature of the present invention is that the two rollers used to roll the abrasive stone have a linkage relationship with each other, so that the relative rotational speeds of the two rollers can be controlled at a certain ratio, thereby improving the crushing efficiency of the stone.

The technical means of the present invention is to provide a transmission device for a crusher, comprising a fixed gear connected to a main shaft of a feeding cylinder, and a movable gear unit connected to an eccentric roller, the movable gear unit having the same axial direction but eccentricity a combination of an outer ring body and an inner ring body, wherein the inner ring body eccentrically combines the eccentric wheel of the eccentric roller; an end surface of the outer ring body is movably provided with a plurality of circumferentially distributed rollers, and the roller The shaft meshes with the fixed gear to be driven to each other, whereby when the eccentric of the eccentric roller rotates at a high speed, the friction force eccentrically drives the inner ring body to vibrate and rotates at a lower speed, and then the friction of the inner ring body with a low rotation speed The eccentrically moves the outer ring body to vibrate and further produces a low-speed rotation, and finally the outer ring body drives the fixed gear to rotate; the stone material is injected from the gap between the feeding cylinder and the eccentric roller, so that the larger particle size of the stone passes through the changing gap. It is crushed and crushed into small-size sand suitable for construction and engineering.

Further, the creation includes a fixed gear that is concentrically placed on a feed. At least one end of the cylinder; a movable gear unit includes an outer ring body and an inner ring body, the inner ring body has a first eccentric hole in the center thereof, and the first eccentric hole cooperates with an eccentric wheel coupled to a driving shaft; The center of the outer ring body has a second eccentric hole, and a plurality of circumferentially distributed rollers are movably disposed at one end surface thereof, and an outer diameter of the inner ring body is smaller than an inner diameter of the second eccentric hole, and the inner ring body is matched In the second eccentric hole, the roller meshes with the fixed gear to be driven to each other.

Preferably, the present invention can provide a plurality of fixed shafts circumferentially distributed at one end of the outer ring body, and a ball bearing is mounted on each fixed shaft as a roller for engaging the fixed gear.

With the crusher transmission of the present invention, in addition to the more efficient and labor-saving crushing of the stone, the transmission mechanism is also reduced in cost due to simplification, and the eccentric roller for rolling the stone can be used. The relative rotation speed of the feeding cylinder is more certain, and the effect of crushing the stone is better, so it is a novelty and progressive creation.
