Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to ore refining material crushing equipment. Background Art

[0002] The development of ore is an important means for people to absorb minerals. Minerals are not necessarily on the surface and need to be mined in mines. In the existing technology, in the mining of mines and mines, the mined ore needs to be crushed, and crushing equipment is needed. There are many types of crushing equipment, such as jaw crusher, hammer crusher, impact crusher, roll crusher and so on.

[0003] After the existing ore is crushed, the size of the ore particles varies greatly. If the ore particles do not meet the requirements, the crushed ore needs to be poured into the ore crusher again for secondary crushing. However, some of the ore particles in the ore crushed once meet the requirements. If all of them are crushed for the second time, it will obviously waste equipment resources and reduce ore processing efficiency. Utility Model Content

[0004] To this end, the utility model provides an ore refining material crushing device, which uses a crushing mechanism to solve the problem that after the ore is crushed, the ore particles have very different sizes and the crushed ore needs to be poured into the ore crusher again for secondary crushing.

[0014] The utility model embodiment has the following advantages:

[0015] 1. The weight of the ore and the inclined surface of the splash plate make the splash plate slide into the obstacle avoidance groove, thereby contracting the spring. At the same time, the splash plates on both sides open to allow the ore to fall into the drum screen. After the ore inside the feed port falls out, the splash plate loses its squeezing force, and the spring force resets the splash plate to block the top of the crushing chamber to prevent the broken stones from splashing out, thereby improving safety during use.

[0016] 2. Through the gaps on the drum screen, the qualified ore falls out of the crushing device through the bottom of the drum screen, and the unqualified ore continues to be hammered and crushed by the hammer crusher body inside the drum screen, so that only the qualified ore can be discharged from the crushing device, preventing the situation where the ore is not completely crushed and needs secondary crushing.

[0017] 3. When the swing arm rotates, the connecting shaft and the through slot cooperate to make the movable arm move back and forth left and right. The movable arm moves through the slide plate to make the connecting plate move back and forth left and right. The connecting plate moves through the rack and the gear to make the hollow cylinder drive the drum screen to rotate forward and backward, so as to screen the broken ore inside the drum screen, prevent the broken ore from accumulating at the bottom of the drum screen to cause blockage, and prevent the discharge of the broken ore from being affected.

[0035] The use process of the utility model is as follows: when using the utility model, an external power supply is connected. When the ore needs to be crushed, the motor 5 is started. The motor 5 rotates through the rotating shaft 6 to make the hammer crushing device body 7 rotate inside the drum screen 8. At this time, the ore is added into the feed port 2 and contacts the splash plate 20. The weight of the ore and the inclined surface of the splash plate 20 make the splash plate 20 slide into the obstacle avoidance groove 3, thereby causing the spring 22 to contract. At the same time, the splash plates 20 on both sides are opened to allow the ore to fall into the drum screen 8, and the rotating hammer crushing device body 7 is used to rotate and hammer the ore, so that the ore is crushed inside the drum screen 8. After the ore inside the feed port 2 falls, the splash plate 20 loses the squeezing force, and the splash plate 20 is reset by the elastic force of the spring 22, and the top of the crushing chamber 4 is blocked to prevent the crushed stones from splashing out, thereby improving the safety during use. The crushed qualified ore passes through the drum screen 8 falls out from the bottom, and the unqualified ore continues to be crushed inside the drum screen 8, so that only the qualified ore can be discharged from the outside of the crushing device 1, so as to prevent the ore from being incompletely crushed and requiring secondary crushing. The swing arm 19 is driven to rotate while the rotating shaft 6 rotates. The swing arm 19 rotates through the cooperation of the connecting shaft 18 and the through groove 17, so that the movable arm 16 moves back and forth left and right. When the movable arm 16 moves, it is connected by the sliding of the slide plate 14 and the slide groove 15 to prevent the through groove 17 from being separated from the connecting shaft 18. At the same time, when the slide plate 14 moves, it drives the connecting plate 13 to move back and forth left and right. The movement of the connecting plate 13 drives the rack 12 to move back and forth, and then the hollow cylinder 10 drives the drum screen 8 to rotate forward and backward through the gear 11 meshing with the rack 12, so as to screen the crushed ore inside the drum screen 8, prevent the crushed ore from accumulating at the bottom of the drum screen 8 to cause blockage, and prevent the discharge of the crushed ore from being affected.
