Description

Technical Field

[0001] This utility model belongs to the field of crushers, and specifically relates to a feeding device for a cone crusher. Background Technology

[0002] Cone crushers, as secondary crushing machinery for medium or fine crushing of ore in mines, have advantages such as strong crushing capacity and high material utilization rate.

[0003] In existing cone crushers, the large vertical drop between the feed belt and the crusher boom cap results in significant potential energy in the ore. Furthermore, when the ore is fed into the crushing chamber from the feed belt via the front chute, it tends to concentrate on one side of the chamber. This can lead to problems such as loosening of the upper frame, burnt-out boom and eccentric bushings, and damage to the hydraulic system and motor shaft, all of which affect the normal operation of the crusher. Long-term operation can also damage the crusher and shorten its service life. Utility Model Content

[0004] The purpose of this invention is to provide a cone crusher feeding device to solve the problem of easy damage to cone crushers during long-term operation in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A cone crusher feeding device includes a cone crusher, the cone crusher including a front chute and a crusher boom cap; the front chute is located directly below the external feed belt, and a foundation buffer plate is fixedly installed at the bottom of the front chute of the cone crusher.

[0007] The shape of the basic buffer plate matches the shape of the bottom of the front slide, and a through hole is provided in the middle of the basic buffer plate.

[0008] The front conveyor is also equipped with a ore discharge hopper, which is cylindrical and has a support ring fixedly fitted in the middle. The lower part of the ore discharge hopper passes through a through hole and is secured to the foundation buffer plate by its own support ring.

[0009] The central axes of the basic buffer plate, the ore feeding hopper, and the crusher boom cap are collinear.

[0010] This utility model also has the following features:

[0011] Furthermore, the inner surface of the front chute of the cone crusher is lined with a liner.

[0012] Furthermore, the basic buffer plate is welded to the bottom of the front chute of the cone crusher.

[0013] Furthermore, the base buffer plate is a high-manganese steel plate.

[0014] Compared with the prior art, this utility model has the following technical effects:

[0015] (I) The cone crusher feeding device of this utility model uses a combination of a base buffer plate and a feed hopper for feeding, guiding the ore directly above the crusher boom cap, avoiding a series of problems caused by the ore impacting one side of the crushing chamber; in the early stage of crushing, some ore fills and accumulates in the gap formed by the feed hopper and the base buffer plate and creates a slope, forming a "ore hitting ore" phenomenon with the subsequent feed ore, which plays a role in buffering the impact force of the ore. At the same time, the accumulated ore protects the protruding support part on the outside of the feeding port, thereby ensuring the overall safe and stable operation of the cone crusher.

[0016] (II) The cone crusher feeding device of this utility model features a symmetrical design for the ore feeding hopper. When the upper part of the ore feeding hopper is severely worn, it can be rotated 180°, extending the service life of the feeding device and reducing labor intensity. The cone crusher feeding device of this utility model has a convenient structure, is easy to operate, and is suitable for large-scale industrial use and promotion. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the overall structure of the cone crusher feeding device of this utility model.

[0018] The labels in the diagram represent the following: 1. Cone crusher; 2. Front conveyor; 3. Crusher boom cap; 4. Feed belt; 5. Foundation buffer plate; 6. Downfeed hopper; 7. Support ring; 8. Liner. Detailed Implementation

[0019] It should be noted that, unless otherwise specified, all components in this utility model are components known in the prior art. For example, the cone crusher, the front conveyor, and the crusher boom cap are all commonly used components known in the prior art.

[0020] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments. All equivalent modifications made based on the technical solutions of this application fall within the protection scope of the present invention.

[0021] like Figure 1 As shown, a cone crusher feeding device includes a cone crusher 1, which includes a front chute 2 and a crusher boom cap 3. The front chute 2 is located directly below the external feed belt 4, and a foundation buffer plate 5 is fixedly installed at the bottom of the front chute 2 of the cone crusher 1.

[0022] The shape of the base buffer plate 5 matches the shape of the bottom of the front slide 2, and a through hole is provided in the middle of the base buffer plate 5.

[0023] The front conveyor 2 is also equipped with a ore discharge hopper 6. The ore discharge hopper 6 is cylindrical, and a support ring 7 is fixedly fitted in the middle of the ore discharge hopper 6. The lower part of the ore discharge hopper 6 passes through a through hole and is secured to the foundation buffer plate 5 by its own support ring 7.

[0024] The central axes of the basic buffer plate 5, the ore feeding hopper 6, and the crusher boom cap 3 are collinear.

[0025] The ore funnel 6 is designed with a symmetrical structure. When the upper part of the ore funnel 6 is severely worn, it can be flipped 180° up and down, which extends the service life of the overall device and reduces labor intensity.

[0026] It should be noted that, Figure 1 The cone crusher 1 shown in the image is part of a cone crusher, including a moving cone, a fixed cone, a crushing chamber, and a front chute 2;

[0027] The cone crusher 1 in this application is a known existing device in the art; those skilled in the art can clearly understand the shape and structure of a complete cone crusher.

[0028] Furthermore, the inner diameter of the ore feeding hopper 6 is matched with the particle size of the ore to be crushed, and its height is matched with the vertical distance from the feed belt 4 to the crusher arm cap 2, ensuring that the ore can enter the crushing chamber of the machine smoothly and continuously.

[0029] As a preferred option, the inner surface of the front conveyor 2 of the cone crusher 1 is lined with a liner 8.

[0030] As a preferred option, the base buffer plate 5 is welded to the bottom of the front chute 2 of the cone crusher 1.

[0031] As a preferred option, the base buffer plate 5 is a high manganese steel plate. As a high-strength steel, high manganese steel will work harden on the surface when subjected to strong impact, forming a hardened layer. The greater the impact load, the deeper the surface hardened layer, the stronger the wear resistance, and the longer the service life.

[0032] In use, the base buffer plate 5 is welded below the liner plate 8 laid on the front chute 2 of the cone crusher, and the feed hopper 6 is placed in the circular hole of the base buffer plate 5. In the initial crushing stage, some ore fills and accumulates in the gap formed by the feed hopper 6 and the base buffer plate 5, creating a slope. During subsequent feeding, the incoming ore and the sloped ore create a "ore-on-ore" phenomenon, buffering the impact force of the ore. Simultaneously, the accumulated ore protects the support ring 7 on the outer side of the feed hopper 6. The feed hopper 6 is positioned directly above the crusher boom cap 7 to prevent unilateral impact from the ore on the crushing chamber, thus avoiding a series of problems.
