The present invention relates to a compactor. Therefore, the configuration of the present invention and its operation will be described in detail with reference to FIGS. 2 to 8.

As shown, there is a mantle core 30 having a conical mantle 20 formed inwardly of the concave 10 having a triangular inner circumferential surface and a mantle core 30 having a dust sealing portion 31 on its outer circumferential surface. There is a support sheet 40 having a curved cross section fastened in the form of a circular ring to the outside of the outer circumferential surface of the main shaft (A), the shock absorbing means of the inside sandwiched between the mantle core 30 and the support sheet 40 There is a dust seal 50 having a horizontal contact portion 51 in close contact with 60. In addition, an elastic spring 61 inserted into a plurality of through holes 41 formed at a predetermined interval to the upper portion of the support sheet 40 and an elastic tube 65 fitted to the outer circumferential surface of the support sheet 40 are formed. The shock absorbing means 60 of the stage structure is formed. Therefore, when they combine to absorb the impact generated when breaking the rock between the inner circumference of the concave 10 in accordance with the interlocking of the mantle 20 through the impact buffer means 60, to prevent the inflow of dust It is.

That is, the present invention borrows the existing concretizer which crushes the rock through the concave 10 having the inner circumferential surface in the shape of the cone and the mantle which is the cone shape. And the mantle core, the support sheet 40 is fastened to the lower end of the mantle 20 is equally applicable. If there is a difference, there is a big difference in that the elastic spring 61 protruding to the upper portion of the support sheet 40 is formed, and the elastic tube 65 positioned to surround the outer circumferential surface of the support sheet 40 is installed. .

The bottom of the cone-shaped mantle 20 has a mantle core having a dust sealing portion 31 protruding downward and the main shaft (B) is integrally coupled to the center. When the main shaft (B) has an eccentric peristaltic movement through the barbell gear, the mantle (20) fastened to the top is also eccentric peristaltic or rotational movement inside the concave (10). By this operation, the rock sandwiched between the concave 10 and the mantle 20 is crushed. At this time, the components of the mantle core, such as the bottom of the mantle 20, the support sheet 40, the dust sealing 50 is also vibrated under the impact, in the present invention, the upper and outer surfaces of the support sheet 40 The shock absorbing means 60 is provided at the end to block the breakage of the gas.

That is, as shown in FIGS. 2 to 8, a plurality of through holes 41 are formed at regular intervals to the upper end of the support sheet 40, and the elastic springs 61 are inserted into the through holes 41, respectively. The site | part interviewed with this support sheet 40 is a mentle core integrated in the lower end of the mentle 20, and the dust sealing 50 of the lower end. More precisely, the dust sealing 50 is placed on the upper portion of the support sheet 40 to be interviewed. Therefore, when the inner circumferential surface of the mantle 20 and the concave 10 causes a collision, the upper surface of the dust sealing 50 and the support sheet 40 also collides. The contact portion of the dust seal 50 is a horizontal contact portion 51, and the contact portion 51 is in a state of being interviewed with the upper end of the elastic spring 61 protruding to the upper portion of the support sheet 40 to absorb shock. can do. The collision generated by the rock fracture between the outer circumferential surface of the mantle and the inner circumferential surface of the concave 10 is transmitted to the lower end of the mantle, wherein the elastic spring 61 is supported by the support sheet 40 and the dust sealing 50. It is a structure that absorbs shocks. The present invention has another shock absorbing structure except for the shock absorbing structure of the elastic spring 61, which is the elastic tube 65 shown in Figs.

The elastic tube 65 is wound around the outer surface of the support sheet 40, the volume is expanded when the elastic tube 65 is inflated, the upper end is protruded to the upper end of the support sheet 40. That is, although the state is wound on the outer surface of the support sheet 40, the upper end is projected to the upper portion of the support sheet 40 is to be able to actually contact the contact portion 51 of the dust sealing 50. Therefore, when an impact is transmitted by the collision between the mantle 20 and the concave 10, the primary shock is absorbed through the elastic spring 61 described above, and the elastic tube 65 when the impact is excessive. Elastic force is applied to achieve the secondary shock absorption.

Another advantage of such an elastic tube 65 in the present invention is that the elastic tube 65 is completely surrounded around the outer peripheral surface of the support sheet 40 can prevent the penetration of dust. When the dust penetrates into the inside of the support sheet 40 in the crusher such as the present invention, which can blow a lot of dust by crushing the rock, various problems occur. For example, in the case of a conventional cone crusher, an embodiment in which a skin or a leather and rubber packing are inserted inside has always resulted in cleaning after a constant use. In addition, in the case of the cone crusher, in which an elastic spring is incorporated to absorb shocks, dust may enter the elastic spring and cause problems in the elastic force. By the way, in the case of the present invention, since the dust to be caught in the inner elastic spring 61 by the elastic tube 65 protruding from the outer circumferential surface of the support sheet 40, the effect is doubled.

Then look at a more detailed configuration and its operation of the present invention.

The elastic spring 61 and the elastic tube 65, the impact buffer means 60 in the present invention, the upper end of the elastic spring 61 is higher than the upper end of the elastic tube 65, the elastic spring at the time of collision It is preferable that the elastic force of the first acts after the elastic force of the elastic tube 65 to act to absorb the shock. As shown in Figure 5 and 6 (a), the elastic spring 61 and the elastic tube 65, which is the shock absorbing means 60 of the present invention has a difference in the installed height. The upper end of the elastic spring 61 is higher than the upper end of the elastic tube (65). If the upper portion of the elastic spring 61 protruding to the top of the support sheet 40 is reduced down by pressing the dust seal 50, the shock is absorbed using only the elastic force of the elastic spring 61. Done. 5 and 6 (b), the bottom surface of the dust sealing 50 presses the upper end of the elastic tube 65, and from this time, the elastic force and the elastic tube of the elastic spring 61 are pressed. The elastic force of 65 acts at the same time to absorb the shock. Eventually, the elastic spring 61, which is the shock absorbing means of the present invention, is installed so that its upper end can be formed at a higher position than the elastic tube 65, and when a certain force is applied to the length of the elastic seal, dust sealing ( It is preferable to provide the elastic tube 65 at a position where the bottom surface of the 50 may be in contact with the upper surface of the elastic tube 65.

Next, in the present invention, the shock absorbing means 60 is preferably made to be vertically interlocked by putting a spring cap 62 on the upper end of the elastic spring 61. 3 and 4 illustrate a spring cap 62 in the form of a cap that can cover the top surface of the elastic spring 61. The spring cap 62 serves to allow the elastic spring 61 to more stably interview the contact portion 51 of the dust seal 50, and at the same time, the elastic spring 61 is formed by the dust seal 50. When it is pressurized, it is capped so as not to be squeezed to the side while condensing. When the spring cap 62 is covered and subjected to the elastic force of the elastic spring 61, the elastic spring 61 is crushed in a vertical direction while exerting elastic force to the inside of the through hole 41 of the support seat 40 to exert elastic force. do. In addition, the spring cap 62 may also serve to prevent the elastic force of the spring from being lost by various types of dust or dirt that may be caught in the elastic spring 61.

In the present invention, the idea of all the inventions focuses on the smooth operation of the shock absorbing means 60 and the direction of increasing its effect. Therefore, various embodiments of the elastic spring 61 and the elastic tube 65 to be the impact buffer 60 is an important matter. This embodiment will now be described in detail with the drawings shown. In the present invention, the elastic tube 65, it is preferable to increase the elastic force by injecting air or nitrogen gas therein.

3 and 4, it is possible to use the air or nitrogen gas to generate a high pressure inside the elastic tube 65 of the rubber material. If the air of the general atmosphere is blown inside the elastic tube 65 to form a constant pneumatic force, the elastic force will be doubled to enhance the function of absorbing shock. Of course, it is also beneficial to inject nitrogen gas instead of the air to form the internal pressure.

In addition, in the present invention, the elastic tube 65 is to be replaced by using a hose 67 of a general rubber material. Although the elastic tube 65 of the above-described embodiment is manufactured and used for the compactor of the present invention, it is also possible to connect a tube or a hose that can be generally used and use the wound around the outer circumferential surface of the support sheet 40 to achieve the same purpose. Can be. Since it is simply to absorb the shock, it is not necessary to have a unique shape or shape, but is wound on the outer surface of the support sheet 40, but the upper end of the support sheet 40 slightly protrudes to form a dust seal 50. Any structure can be used as long as it can exert elasticity during the interview.

Of course, the inside of the hose 67 is preferably used to fill the fiber yarn 68 to increase the elastic force. The inside of the hose is filled with a fiber that can generate a higher elasticity to increase the function. Fiber yarn 68 may be used to put a general fiber or cotton, elastic yarns and rubber pieces to generate elasticity. In terms of durability, it may be more effective to absorb the impact by filling the fiber yarn 68 than it is empty or filled with air.

Next, since the elastic tube 65 of the present invention must be wound around the outer circumferential surface of the support sheet 40 to generate elastic force, securing a stable position is important. Therefore, it is preferable to use the embodiment shown in Figures 3 and 4 shown.

That is, in the support sheet 40 to which the elastic tube 65 is wound, the support step 47 is formed so that the elastic tube 65 is not pushed to the lower end when pressed. When the close contact portion 51 of the dust sealing 50 comes down while pressing the elastic tube 65, the elastic tube 65 is also subjected to the same pressure to remove the fear to flow down the outer peripheral surface of the support sheet 40. . Although the elastic tube 65 is wound on the outer circumferential surface of the support sheet 40 and is pressed, the bottom of the elastic tube 65 has a support step 47 protruding from the support sheet 40, so that the elastic tube 65 is formed. It is blocking the case of pushing down to the bottom. By supporting the lower end of the elastic tube 65 more stably, while increasing the absorbing power of the impact while ensuring its durability.

Meanwhile, in the support sheet 40 to which the elastic tube 65 is wound for the same purpose, the seating groove 72 is formed around the outer circumferential surface thereof so that the elastic tube 65 can be fitted to the outer surface of the support sheet 40. It is preferable to form 3 and 5 illustrate a support sheet 40 in which the seating grooves 72 are not formed, and FIGS. 4 and 6 illustrate embodiments in which the seating grooves 72 are formed on the side surfaces of the support sheet 40. Doing. The seating groove 72 allows the elastic tube 65 to secure its position more stably when the outer circumferential surface of the support sheet 40 is wound. 3 and 5, the elastic tube 65 wound on the support sheet 40 without a seating groove is subjected to a large force or a load and an impact to the upper side, the elastic tube 65 is supported by the support sheet 40 There is also a chance to climb to the top of). However, the inner side of the support sheet 40, more precisely to form a seating groove 72 to dig into the inner circumferential surface to the upper portion of the support step (47), the inner circumferential surface of the elastic tube 65 is pinched in the seating groove 72 If you can, it won't fall easily. It will perform a function of securing a more stable position and absorbing the desired impact.

In particular, although Fig. 4 and 7 of the present invention shows a seating groove 72 having a rounded inner circumferential surface, it is not limited thereto. The tapered mounting groove 72 may be used instead of the round surface.

In other words, in the present invention, the seating groove 72 may be formed in a tapered oblique plane whose cross section is smoothly rounded or inclined toward the inner circumferential surface.
