Description

Technical Field

[0001] The utility model relates to the technical field of ore mining, in particular to a crusher. Background Art

[0002] Ore is not only an important resource for economic development, but also the foundation of scientific and technological progress and scientific research. It plays a vital role in the progress and development of human society. Antimony ore is a type of ore. Antimony ore refers to mineral rocks containing antimony. As an important metal element, antimony has a wide range of application value in the industrial field. In the antimony mining process, large pieces of antimony ore need to be crushed into the required size by a crusher. The crusher is a pulverizing machine that crushes the mined antimony ore and other raw ores into small particles through squeezing and bending.

[0003] In existing crushers, the rotor rotates at high speed, feeding antimony ore and other ore materials into the crushing box. The high-speed rotating hammers exert a strong impact on the antimony ore and other ore materials, causing them to be impacted and crushed. Antimony ore and other ore material particles smaller than the sieve plate mesh size pass through the sieve mesh and are discharged from the bottom. The larger antimony ore and other ore materials are blocked on the sieve plate and continue to be crushed by the impact, grinding, and squeezing of the hammers.

[0004] In existing crushers of this type, some antimony ore and other ore materials may be over-crushed into fine powder, while other parts of antimony ore and other ore materials have not been completely crushed to the appropriate particle size. When processing antimony ore and other ore materials with high hardness and strong abrasiveness, the service life of the hammer head will be greatly shortened, and the hammer head needs to be replaced frequently. For this reason, we propose a crusher. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a crusher with multi-layer crushing, so that the product particle size is more uniform, the number of cyclic crushing times of ore materials such as antimony ore is reduced, the production efficiency is improved, the service life of the hammer head is extended, the maintenance cost and downtime of the equipment are reduced, and the problems in the background technology can be effectively solved.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a crusher comprising a bottom plate, an upper surface of which is provided with a shell, and a crushing mechanism;

[0007] Crushing mechanism: It includes a rotating column, a turntable, a breaking hammer, a rotating column and a crushing roller. The upper end between the left and right inner walls of the shell is rotatably connected with a rotating column, and the outside of the rotating column is provided with evenly distributed turntables. The two adjacent turntables are respectively rotatably connected with breaking hammers through pin shafts. The rotating columns are rotatably connected to the lower ends between the left and right inner walls of the shell, and the outside of the rotating columns are respectively provided with crushing rollers. The double-layer crushing treatment by the hammer head and the crushing roller is ensured to ensure the uniformity of the crushed ore materials such as antimony ore, instead of the traditional crushing form that only uses the hammer head. At this time, the crushing burden of the hammer head will be greatly reduced, and the wear of the hammer head is reduced to a certain extent, and there is no need to frequently replace the hammer head.

[0008] Furthermore, a single chip microcomputer is provided on the outside of the base plate, and an input terminal of the single chip microcomputer is electrically connected to an external power supply to provide electrical connections for various electrical appliances.

[0009] Furthermore, the crushing mechanism also includes a pulley and a motor 1. The motor 1 is arranged at the rear end of the upper surface of the base plate. The left end of the output shaft of the motor 1 and the left end of the rotating column are respectively provided with pulleys. The two pulleys are connected by a belt. The input end of the motor 1 is electrically connected to the output end of the single-chip microcomputer to ensure the stable operation of the preliminary crushing.

[0010] Furthermore, the crushing mechanism also includes gear 1, gear 2 and motor 2. Motor 2 is arranged at the rear end of the upper surface of the bottom plate. Gear 1 is provided at the right end of the output shaft of motor 2. Gear 2 is respectively arranged at the right end of the rotating column. Two adjacent gears 2 are meshed and connected. Gear 1 is meshed and connected with the gear 2 on the rear side. The input end of motor 2 is electrically connected to the output end of the single-chip computer to achieve uniform crushing.

[0011] Furthermore, lifting blocks are provided on the left and right sides of the shell to facilitate movement.

[0012] Furthermore, a feed port is provided at the front side of the shell, and a discharge port is provided at the bottom end of the shell, so as to facilitate the crushing of ore materials such as antimony ore.

[0013] Furthermore, a bracket is provided at the bottom end of the base plate to provide stable support.

[0014] Furthermore, a threaded hole is provided on the edge of the feed port, and the feed port can be connected to a material guide plate or a protective cover through threads. Installing the material guide plate facilitates feeding, and installing the protective cover can prevent the crushed material from splashing out.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the crusher has the following advantages:

[0016] 1. Antimony ore and other ore materials are initially crushed under the high-speed operation of the breaker hammer. After crushing, the antimony ore and other ore materials with a size smaller than the gap between the crushing rollers are directly discharged. The ore materials with a size larger than the gap between the crushing rollers cannot be discharged and will be discharged after being squeezed and crushed by the crushing rollers. The double-layer crushing process of hammer head and crushing roller extrusion ensures the uniformity of the crushed antimony ore and other ore materials.

[0017] 2. When processing ore materials with high hardness and strong abrasiveness such as antimony ore, the high-speed crushing hammer is used for preliminary relative crushing. At this time, the crushing does not need to be completed in one step. The subsequent deep crushing is postponed and handed over to the subsequent crushing roller to replace the traditional crushing method using only the hammer head. At this time, the crushing burden of the hammer head will be greatly reduced, and the wear of the hammer head will be reduced to a certain extent, and there is no need to frequently replace the hammer head.
