Hereinafter, with reference to the accompanying drawings will be described in detail the advantages, features and preferred embodiments of the present invention.

2 is a perspective view of a jaw crusher including a shock absorber according to the present invention. As shown in Figure 2, the jaw crusher comprising a shock absorber according to the present invention, the transport device 10 is inputted and transported construction waste, jaw crusher 20 and the jaw crusher to crush the construction waste to a certain size It includes a shock absorber 30 for buffering the impact of the construction waste discharged from the discharge to the conveyor belt (40). Under the shock absorber 30, a conveyor belt 40 for transferring the crushed construction waste to the next process is disposed.

The conveying apparatus 10 transfers the construction wastes collected from the demolition site, in particular, aggregates and cement agglomerates, and the injected construction wastes to the jaw crusher 20. The conveying apparatus 10 may use various conveying systems such as a conveyor belt or a bend.

The jaw crusher 20 shreds the construction waste conveyed by the conveying apparatus 10 to a predetermined size. Jaw crusher 20 is a device used for primary crushing of gemstones such as 200 to 350mm in size, mainly crushing using a compressive force. One of the jaws, a steel plate made of steel disposed on both sides of the jaw crusher 20, is fixed and the other is moving. Rotates along the wheel and the gap between the two jaws changes. Therefore, when the construction waste such as aggregate or cement or concrete mass of several cm to 1m is put between the jaws on both sides, the gap between the jaws is changed to apply pressure to break the injected construction waste, and the crushed construction waste is the weight and the jaw. Is discharged to the lower discharge port (not shown) by the pushing force while rotating. Jaw crusher 20 is determined according to the size of the jaw and can adjust the size of the construction waste is crushed by adjusting the bottom gap of the fixed jaw and the moving jaw, that is, the outlet gap. In particular, movable jaw crushers are so powerful that they can break even the hardest rock types.

The shock absorber 30 is disposed below the outlet of the jaw crusher 20 to discharge construction waste crushed by the jaw crusher. The shock absorber 30 buffers the impact of the construction waste falling out of the jaw crusher 20 and then transports it toward a specific direction (front in FIG. 2) to be discharged to the conveyor belt 40. Therefore, the crushed construction waste is buffered by the shock absorber 30 without falling directly from the jaw crusher 20 to the conveyor belt 40, thereby greatly alleviating the impact on the conveyor belt, thereby damaging the conveyor belt. Can be prevented.

Conveyor belt 40 is disposed in the lower portion of the shock absorber 30 is crushed by the jaw crusher 20 and conveys the construction waste transported by the shock absorber to the next process. The next process of conveying the construction waste by the conveyor belt 40 includes a sorting / classifying process of shredded construction waste or a shredding process by an impact crusher or the like.

Figure 3 is a perspective view of the shock absorber according to the present invention from the back, Figure 4 is a side view of the shock absorber according to the present invention, Figure 5 is a cross-sectional view of the crank according to the present invention. Referring to Figures 3 to 5 the configuration of the shock absorber according to the present invention will be described.

The shock absorber 30 according to the present invention includes a flat plate-shaped frame 31, a buffer spring 34 for supporting the lower part of the frame, a crank 35 and a crank for transmitting a vibration force in a specific direction to the frame. It includes a drive motor 36 for driving.

The frame 31 has a flat plate shape and is disposed between the lower part of the outlet of the jaw crusher 20 and the upper part of the conveyor belt 40 to receive and transport the construction waste discharged through the outlet to the conveyor belt. Discharge. Preferably, the frame 31 is arranged to be inclined downward by a predetermined angle toward the front. Frame 31 transfers the construction waste in a specific direction (front in Figure 2) by the vibration of the crank in conjunction with the lower crank (35). The material of the frame 31 is to use a steel plate of a certain thickness of high strength in order to prevent damage due to the impact of construction waste.

On the other hand, the frame 31 is composed of a plurality of reinforcing beams spaced apart at regular intervals rather than a flat plate shape so as to separate small-sized garbage or impurities from the construction waste discharged by the jaw crusher 20. It may be. In this case, garbage or impurities smaller than the spaced interval between the reinforcing beams among the construction wastes introduced into the shock absorber 30 are discharged to the lower portion of the frame 31 through the space between the reinforcing beams.

In addition, in order to prevent the construction waste put into the frame 31 to be jumped out of the frame by vibrating while being transferred in a specific direction, it is preferable to form side walls 32 of a predetermined height on both sides of the frame.

In addition, the plane of the frame 31 to include a guide 33 for collecting and discharging construction waste to the center of the frame. Preferably, the two guides 33 of a certain height are arranged to face each other. At this time, the two guides 33 form a shape in which the interval gradually narrows toward the front, that is, the discharge portion of the frame adjacent to the conveyor belt 40 at a predetermined position in the front and rear direction of the frame 31. Therefore, the construction waste is transported forward along the plane of the frame 31 and collected in the center by the guide 33 so that it can be completely discharged to the conveyor belt 40 without falling to the floor when discharged from the frame.

The shock absorbing spring 34 is connected to the lower portion of the frame 31 to support the lower portion of the frame to absorb the impact of the construction waste, and in conjunction with the crank 35 to allow the frame to vibrate. Preferably, it is to include a plurality of buffer springs 34 to stably support the frame 31 and to effectively absorb the impact caused by construction waste.

The crank 35 is integrally installed on the frame 31 and rotates in one direction in association with the driving motor 36. The drive motor 36 and the crank 35 are interlocked by the drive belt 37. The crank 35 receives the driving force from the driving motor and rotates in one direction to convert the force generated by the rotational motion into a linear reciprocating motion in a specific direction. Specifically, the crank is rotated up and down by the driving motor. It vibrates and converts into a force directed in a specific direction (front in FIG. 2). At this time, since the crank 35 is integrally installed with the frame 31, the vibration force of the crank is transmitted to the frame to vibrate the frame together.

As shown in FIG. 4, the crank 35 has a tapered shape in cross section from one side end to the other end in the imaginary circle, and the center of the imaginary circle is interlocked with the driving motor 36. Thus, the distance from the center of the circle to each end of the crank 35 is different. If the distance from the center of the circle to one end of the crank 35 is a and the distance from the center of the circle to the tapered other end of the crank is b, a becomes larger than b. The distance from the center of the circle to each end can be modified as needed. Thus, when the crank 35 rotates and one end with a distance from the center of the circle goes down from the top to bottom, i.e., when one end moves from the position of 90 ° to the position of -90 ° through the position of 0 °, The tapered other end with the distance b from the center of the ascends up to be at a position of 90 °. Accordingly, the height of the crank at the center of the circle is reduced from a to b, resulting in a force descending by (a-b). On the contrary, when the tapered other end descends from the position of 90 ° to the position of -90 ° through the position of 0 °, one end is raised to the position of 90 °, so the height of the crank at the center of the circle is b to a. This increases the force by (ab). At this time, the rotation direction of the crank is to be the transport direction of the construction waste. Specifically, one end of the crank is rotated in a direction from top to bottom toward the front. Accordingly, a force that vibrates up and down while the crank 35 rotates is generated, and directionality is added to the force that vibrates up and down by the rotation direction of the crank, so that the conveyor belt 40 in a specific direction, that is, in FIG. Pushing force toward the front is applied to transport the construction waste is discharged to the conveyor belt.

Of course, the structure of the crank 35 may be modified in various ways.

One portion of the frame 31 distributes the force applied to the frame 31 when the crushed construction waste falls to the frame 31 of the shock absorber as the shock absorber of the present invention vibrates by the rotation of the crank 35. The grooves can be prevented from being dug, and eventually the life of the shock absorber 30 can be extended.

As described above, the jaw crusher including the shock absorber according to the present invention has a remarkable effect of preventing damage to the conveyor belt because the shock absorbing the construction waste discharged from the jaw crusher and then discharged to the conveyor belt.

In other words, jaw crusher comprising a shock absorber according to the present invention,

Firstly, a shock absorber is included between the jaw crusher for crushing construction waste to a certain size and the conveyor belt for conveying the crushed construction waste, so that the construction waste discharged from the jaw crusher does not fall directly onto the conveyor belt but is impacted by the shock absorber. This relaxed release to the conveyor belt prevents the conveyor belt from tearing or damage due to shredded construction waste and significantly reduces maintenance and repair costs.

Secondly, by forming side walls of a certain height on both sides of the frame of the shock absorber to prevent construction waste transported by the vibration of the frame to protrude out of the frame, it is possible to prevent the injury of the operator,

Thirdly, because the shock absorber is vibrated by the crank and the drive motor, the impact of the construction waste shredded in the jaw crusher is more absorbed when it falls on the frame of the shock absorber, thereby extending the life of the shock absorber.

Finally, the construction waste transported along the frame is collected in the center of the frame using a guide, so that the construction waste can be completely discharged to the conveyor belt without falling to the floor.
