Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, in particular to a high-efficiency crushing device for mining rocks. Background Art

[0002] The development of human society depends on materials, and mineral resources are one of these important material bases. At present, more than 95% of energy, more than 80% of industrial raw materials and more than 70% of agricultural production materials come from mineral resources. Mineral resources mostly come from mines, and open-pit mining of building stone mines, as part of various types of mines in my country, accounts for about 60% of the total number of mines. Therefore, the degree of its comprehensive utilization of resources plays a decisive role in the overall development of comprehensive utilization of mine resources in my country. When blasting and mining the rocks on the mines, sometimes the rocks after blasting are large in size, and rock crushing equipment is needed for secondary crushing.

[0003] At the same time, mine stone refers to a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. Mine stone is an indispensable and important material in the construction industry. In the mining and reuse of mine stone, in order to facilitate the transportation of ore, large pieces of ore need to be broken into smaller pieces through crushing equipment. In the process of crushing mine stone, crushing equipment is needed.

[0004] The structure of the rock crushing device used in traditional mining is relatively simple. The force-bearing area during crushing is small, the crushing force utilization rate is low, and the crushing efficiency is low. Traditional mining rock crushing equipment has limitations in processing speed and efficiency, especially in continuous operation and large-scale processing. During force crushing, the crushing of the mined rock fragments is not uniform, resulting in unsatisfactory processing effect. The surface area of ​​larger rock fragments is relatively small, resulting in slow crushing conduction speed. During the crushing process, the outer layer of the rock fragment particles will be crushed first, while the inside remains solid, resulting in uneven force crushing. Due to the large volume of the particles, the internal mass transfer process slows down and the overall reaction rate decreases, which leads to prolonged mining duration or requires higher crushing temperature and energy to complete the force crushing process. Large particles are difficult to be completely and evenly crushed by the crushing elements, which increases the technical challenges in the operation process, especially when the contact area between the mining rock and the crushing rod is limited, it takes longer to achieve sufficient force crushing and processing. Summary of the invention

[0021] Working principle: First, start the linkage motor, which drives a group of external toothed pulleys installed on its output shaft to rotate on the fixed frame. The rotation of this group of external toothed pulleys drives another group of external toothed pulleys to rotate through a group of internal toothed belts, and makes the internal toothed belt operate. The inlaid blocks installed on the side walls of the internal toothed belt move with the operation of the internal toothed belt and follow the operation route of the internal toothed belt. The sliding column installed on the top of the inlaid block slides on the driving slide installed inside the driving platform. The movement of the inlaid block drives the driving platform to move through the sliding column, so that the driving platform slides horizontally on the slide rail along the slider installed at the bottom. When the inlaid block reaches the operating corner of the internal toothed belt, it rotates 180 degrees by itself, and the sliding column on the top also slides horizontally inside the driving slide. The inlaid block drives the driving platform to move in the opposite direction, so that the driving platform reciprocates back and forth, and makes the mining rocks that are in contact with the crushing mechanism fully vibrate, so that the rotating disk rotates inside the tower-shaped load-bearing pool along the fixed bearing, and the large-diameter fixed ring installed on the left side of the rotating disk. , a middle diameter fixing ring 1, a small diameter fixing ring 1, a large diameter fixing ring 2 installed on the right side of the fixing plate, a middle diameter fixing ring 2 and the inner wall of the middle diameter fixing ring 2 are all installed with multiple sets of circumferentially distributed double-conical impact rods, and the double-conical impact rods installed on the rotating plate and the fixed plate are cross-arranged. When the rotating plate rotates, the double-conical impact rods installed on the rotating plate and the double-conical impact rods installed on the fixed plate form a relative rotational motion, and because the diameter of the large diameter fixing ring 1 is larger than that of the large diameter fixing ring 2, the diameter of the middle diameter fixing ring 1 is larger than that of the middle diameter fixing ring Second, the diameter of the small-diameter fixed ring 1 is larger than that of the small-diameter fixed ring 2, so that when the rotating disk rotates, the double-conical impact rod can generate intensive extrusion force and extremely small contact area. When the mining rocks are guided between the rotating rotating disk and the fixed disk through the input channel, the intensive double-conical impact rods continuously impact and crush the mining rocks. Moreover, due to the annular characteristics, the mining rocks will rotate multiple times between the rotating disk and the fixed disk, and contact the double-conical impact rods multiple times, so as to achieve the effect of full contact, impact and crushing.

[0022] The present invention provides a high-efficiency crushing device for mining rocks. It has the following beneficial effects:

[0023] 1. The present invention makes the rotating disk rotate along the fixed bearing inside the tower-shaped bearing pool, and the large-diameter fixed ring 1, the middle-diameter fixed ring 1, the small-diameter fixed ring 1 installed on the left side of the rotating disk, and the large-diameter fixed ring 2, the middle-diameter fixed ring 2 and the inner wall of the middle-diameter fixed ring 2 installed on the right side of the fixed disk are all equipped with multiple groups of circumferentially distributed double-conical impact rods, and the double-conical impact rods installed on the rotating disk and the fixed disk are cross-arranged. When the rotating disk rotates, the double-conical impact rods installed on the rotating disk and the double-conical impact rods installed on the fixed disk form a relative rotational motion, and because The diameter of large diameter fixing ring one is larger than that of large diameter fixing ring two, the diameter of medium diameter fixing ring one is larger than that of medium diameter fixing ring two, and the diameter of small diameter fixing ring one is larger than that of small diameter fixing ring two, so that when the rotating disk rotates, the double-conical impact rods can generate intensive extrusion force and extremely small contact area. When the mined rocks are guided between the rotating rotating disk and the fixed disk through the input channel, the intensive double-conical impact rods continuously impact and crush the mined rocks, so that the original minerals of the mined rock fragments can fully contact and bear the force and carry out efficient contact crushing.

[0024] 2. The present invention drives a group of external toothed pulleys installed on its output shaft to rotate on the fixed frame through a linkage motor. The rotation of the group of external toothed pulleys drives another group of external toothed pulleys to rotate through a group of internal toothed belts, and the internal toothed belt is operated. The inlaid blocks installed on the side walls of the internal toothed belt move with the operation of the internal toothed belt and follow the operation route of the internal toothed belt. The sliding column installed on the top of the inlaid block slides on the driving slide groove installed inside the driving platform. The movement of the inlaid block drives the driving platform to move through the sliding column, so that the driving platform slides horizontally on the slide rail along the sliding block installed on the bottom. When the inlaid block reaches the operating corner of the internal toothed belt, it rotates 180 degrees by itself, and the sliding column on the top also slides horizontally inside the driving slide groove. The inlaid block drives the driving platform to move in the opposite direction, so that the driving platform reciprocates back and forth, and makes the mining rocks contacted and crushed inside the contact crushing mechanism fully vibrate, so that a small range of accumulation occurs when the contact crushing mechanism works.
