[Prior art]

 In general, a cone crusher is a kind of machine that grinds relatively large stones into fine stones, and is generally used for secondary grinding and tertiary grinding. FIG. 1 is a conventional hydraulic conical crusher, which includes:

The upper body 3 is fixed above the lower body 2, has a concave weight plate 31 provided on the inner edge thereof, and has a material feed room 32 and a material dividing board 33 provided above the upper body 3. The divider 33 is driven by a motor 1 fixed on a frame 321 on the side of the material feed roam 32. As shown in FIG. 2, the position spindle 4 is located at the center of the upper and lower bodies 2 and 3, and its upper end is placed in a stereotactic body 35 located at an intermediate position of the upper body 3. A bearing metal 36 ′, a bearing metal seat 36 and a shaft sleeve 37 are provided in the body 35, a oscillating weight body 40 is provided in a middle portion of the main shaft 4, and a convex weight plate 41 is provided on a conical surface of the oscillating thrust body 40. A pressing nut 401 is provided above the convex weight plate 41.

The eccentric body 5 is located around the lower step of the main shaft 4 and presents a circular body, the bottom end of which extends outward to form a coupling surface 51, and the convex edge of the hydraulic cylinder 6. It is placed on the copper piece 601 above the surface 60, and a large bevel gear 52 is provided on the coupling surface 51 so as to mesh with the small bevel gear 22 of the transmission shaft 21. A hydraulic cylinder 6 is provided, an upper end of the hydraulic cylinder 6 is an open end used to insert a bottom end of the main shaft 4, and an outer periphery of the open end forms a convex edge surface 60 and A copper piece 601 is provided on the edge surface 60 to support the eccentric body 6, a piston 61 is provided in the hydraulic cylinder 6, and a lower stopper thrust plate 62 and a stop push plate 63 are provided on the piston 61, and An upper stopper plate 42 is provided at the bottom end of the main shaft 4, which is a stopper above the piston 61. The transport pipe 64 is supported at a predetermined position by a thrust plate 63 and is connected to a hydraulic pump (not shown) at the bottom edge of the hydraulic cylinder 6.

Thus, when the transmission shaft 21 rotates the eccentric body 5, the main shaft 4 performs a conical operation with the rotation of the eccentric body 5 and the inner metal sleeve 54 inside, and the main shaft 4 operates with the piston 61. The lifting and lowering operation allows the grinding gap to be adjusted between the concave and convex weight plates 31 and 41 by moving up and down in the inner metal sleeve 54 without stopping the machine during operation, thereby saving time. And it has the effect of saving labor and increasing production capacity.

As shown in FIG. 2, the main shaft 4 is located at the center of the upper and lower bodies 2, 3, and the upper end is placed in a stereotactic seat 35 intermediate the upper body 3, and A fixed type shaft copper seat 36, a bearing metal 36 ', and a shaft sleeve 37 are provided in the positioning body 35 and used for positioning the upper end of the main shaft 4, and this is used as a rotation center fulcrum, and the main shaft 4 is eccentric at the lower stage. A conical swinging motion can be performed with the rotation of the body 5.

[0007]

[Problems to be solved by the invention]

 However, in the above-described localization fulcrum localization structure of the main shaft 4, in actual use, the bearing metal 36 'is worn by continuous rotation, and when the friction reaches a certain level, the clearance increases to increase the rotation of the main shaft 4. The situation in which the fulcrum is loosened occurs, and once the loosened condition occurs, the upper end is easily shaken when the main shaft 4 performs the eccentric oscillating motion, so that damage is easily generated, so that the bearing metal 36 'needs to be constantly replaced.

The main object of the present invention is that the clearance of the bearing metal seat is adjustable, so that it does not loosen after wear due to the use of the bearing metal, and always keeps the eccentric rotation of the main shaft smoothly. Another object of the present invention is to provide a bearing metal seat for localization of a main shaft of a conical crusher, which enhances an effect of extending a service life.

[0009]

[Means for Solving the Problems]

 The present invention relates to a kind of bearing metal seat for localization of a main shaft of a conical crusher, which includes: The bearing metal seat is composed of an upper bearing metal seat and a lower bearing metal seat, and is disposed above and below the bearing metal of the main shaft, respectively, and the top and bottom surfaces of the upper and lower bearing metal seats are convex edges. In addition, a few localization holes are provided on the protruding edge body, and a vertical bolt is inserted to further position the upper and lower bearing metal seats on the localization seat body of the upper body. Use a screw hole in each stereotactic space to tighten the necessary number of adjustment screws, and fix the stereotaxic seat with the heads of the upper and lower adjustment screws at the same time. The middle bearing metal is firmly connected to the lower bearing metal seat, and a gap is reserved in the upper and lower bearing metal seats in advance.

[0010] Thus, in the bearing metal seat adjustable structure, when the bearing metal seat is worn to some extent, the eccentric swaying rotation of the main shaft can be smoothly held by merely tightening each adjustment screw evenly. Without loosening, it saves the number and time of replacing bearing metal seats and enhances the effectiveness of extending service life.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, as shown in FIG. 3 and FIG. 4, one embodiment of the present invention is an improvement to the localization structure of the rotation fulcrum at the upper end of the main shaft in the conical crusher. The bearing metal seat 36 used for localization of the main shaft 4 is constituted by an upper bearing metal seat 36A and a lower bearing metal seat 36B, and is placed above and below the bearing metal 36 'of the main shaft 4, respectively. A convex body 361 is formed on the top and bottom surfaces of the seats 36A and 36B, and a few positioning holes 362 are provided on the convex body 361 so as to face each other, and a vertical bolt 363 and a nut 363 are inserted. The lower bearing metal seats 36A, 36B are used to localize on the localization seat 35 of the upper body 3 of the conical crusher.

Further, a screw hole 364 is provided between each of the localization holes 362 to be used to tighten a required number of adjustment screws 365, and the localization seat 35 is simultaneously fixed with the heads of the upper and lower adjustment screws 365. The upper and lower bearing metal seats 36A and 36B firmly connect the intermediate bearing metal 36 ', and a gap S is reserved between the upper and lower bearing metal seats 36A and 36B in advance.

As a result, the bearing metal seat 36 has an adjustable structure, and when the bearing metal 36 ′ is worn to a certain degree, the eccentric swaying rotation of the main shaft 4 can be smoothly performed by merely tightening each adjusting screw 365 evenly. It can be retained and not loosened, saving the number and time of replacement of the bearing metal seat 36 'and increasing the effectiveness of extending the service life. An oil seal 366, a dustproof block 367, and a dustproof block positioning plate 368 are further provided on the bottom surface of the lower bearing metal seat 36B.

The gap S between the upper and lower bearing metal seats 36A, 36B is used by the injection pipe 369 to send lubricating oil to the bearing metal 36 'for lubrication. In addition, a shaft sleeve 37 is provided on the outer periphery of the main shaft 4, and is fixed to the main shaft 4 by a shaft end plate 38 and a positioning member 39. When assembling the present embodiment, the lower bearing metal seat 36B → the oil seal 366 → the dustproof block 367 → the dustproof block bottom plate 368 → the bearing metal 36 ′ → the upper bearing metal seat 36A → the bolt 363 → the adjusting screw 365 in this order. The upper body 3 is assembled into the upper body 3 and is further assembled on the main shaft 4 so that the upper end of the main shaft 4 can use the bearing metal 36 'as a fulcrum of the eccentric swing rotation.

With the above configuration, even when the bearing metal 36 ′ has been worn to some extent, it is not necessary to immediately replace the bearing metal 36 ′, and the adjustment screw 365 is simply adjusted to adjust the upper and lower bearing metal seats. Only by connecting 36A and 36B, there is no defect that the upper end of the main shaft 4 is loosened due to the wear of the bearing metal 36 '. When the bearing metal 36' has already worn out until it can no longer be used, it must be replaced. I just need.

In the present embodiment, by adopting such an adjustment method, the life of the bearing metal 36 ′ can be increased by about three times or more compared to employing the method of the fixed shaft bearing metal seat. In addition, the time for replacing the bearing metal 36 'can be saved. Therefore, the life of the bearing metal 36 'is prolonged, and the effect of reducing the cost is enhanced.
