[0002] In the mining of mines and mines, the mined ore needs to be crushed, which requires the use of crushing equipment, and there are many types of existing crushing equipment.

[0003] For example, Chinese invention CN117463445B discloses an ore crushing equipment, which drives the corresponding crushing rollers to rotate towards each other, so that the ore falls between the oppositely arranged crushing rollers and is squeezed by multiple crushing rollers to perform the first crushing of the ore. Large pieces of first crushed stone will roll along the inclined screening plate to between the first extrusion plate and the second extrusion plate. The screening plate can also drive the second extrusion plate to move up and down during the reciprocating swinging process, thereby squeezing and crushing the large pieces of first crushed stone, that is, secondary crushing.

[0004] However, in the above-mentioned prior art, when two oppositely arranged crushing rollers are used to crush the ore, the ore is crushed by the bite of the two crushing rollers. Due to the high hardness of the ore, the ore is often stuck by the bite of the two crushing rollers, or the ore is too large to be bitten by the two crushing rollers, resulting in poor overall crushing effect and crushing efficiency.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0031] See also Figure 1 , 2 As shown in Figure 5, the present invention is an ore crushing equipment, including a frame 1, the frame 1 is fixedly connected to a fixed jaw 2, slidably connected to a movable jaw 3, and connected to a driving mechanism that is transmission-connected to the movable jaw 3.

[0032] Specifically, the frame 1 includes a base support 101, two side plates 102 connected to the base support 101, a mounting support structure is provided on the base support 101, the base support 101 and the mounting support structure can be a casting structure, and the base support 101 is arched, so that a conveying device can be provided below it. The fixed jaw 2 is connected and fixed to the mounting support structure of the base support 101, and the movable jaw 3 is slidably connected between the two side plates 102 through a guide rail slider assembly.

[0033] like Figure 2 , 4 As shown in FIG. 6 , the driving mechanism includes an eccentric shaft 4 rotatably connected between two side plates 102 , a driving motor 401 drivingly connected to the eccentric shaft 4 is fixedly connected between the two side plates 102 , and the eccentric shaft 4 and the driving motor 401 can be driven by gears.

[0034] The eccentric shaft 4 is rotatably connected to two or more fixed sleeves 402. In this embodiment, two of the fixed sleeves 402 are taken as examples. Both fixed sleeves 402 are fixedly connected to a slider. A sliding groove can be set on the back of the movable jaw 3, and the slider is slidably connected to the sliding groove of the movable jaw 3, and the sliding direction of the slider is horizontal. During the rotation of the eccentric shaft 4, since the slider can slide in the horizontal direction, it will not drive the movable jaw 3 to move horizontally. When the eccentric shaft 4 rotates to cause the fixed sleeve 402 to move up and down, the slider drives the movable jaw 3 to move up and down, so that the rotation of the eccentric shaft 4 causes the movable jaw 3 to only produce up and down reciprocating motion.

[0035] The fixed jaw 2 includes a coarse crushing section 201 and a fine crushing section 202, and the angle between the working surface of the coarse crushing section 201 and the vertical direction is greater than the angle between the working surface of the fine crushing section 202 and the vertical direction. The working surface of the movable jaw 3 is arranged to be inclined downward and parallel to the working surface of the fine crushing section 202, so that the distance between the movable jaw 3 and the coarse crushing section 201 gradually decreases and is greater than the distance between the movable jaw 3 and the fine crushing section 202.

[0036] like Figure 5 As shown, the working surface of the movable jaw 3 is inclined downward, and the angle β with the vertical direction is 20°~45°, and the angle α between the working surface of the coarse crushing section 201 and the working surface of the movable jaw 3 is 15°~30°. The movable jaw 3 is driven by the driving mechanism to reciprocate up and down, and cooperates with the coarse crushing section 201 of the fixed jaw 2 to perform preliminary crushing of the ore. The ore after preliminary crushing automatically rolls to the fine crushing section 202. At this time, the movable jaw 3 cooperates with the fine crushing section 202, and since the mutual distance is smaller, further crushing of the ore is achieved.

[0037] Among them, the working surface of the movable jaw 3 is evenly provided with crushing teeth 302, and the crushing effect of the ore can be improved by squeezing the ore through the crushing teeth 302. The working surface of the fine crushing section 202 is evenly provided with broken fine teeth 205, and the cross-section of the broken fine teeth 205 is smaller than that of the crushing teeth 302, and the distribution density is greater than the distribution density of the crushing teeth 302. By using smaller and denser crushing teeth 302, the further crushing effect of the ore can be improved to ensure the overall crushing effect.

[0038] By setting the movable jaw 3 parallel to the working surface of the fine crushing section 202, the movable jaw 3 reciprocates up and down, and produces a downward pressing and kneading effect on the ore between the movable jaw 3 and the fine crushing section 202, which is more conducive to crushing the mine and improving the crushing effect. In addition, since the movable jaw 3 reciprocates up and down, it can effectively avoid the situation where the ore is stuck in the equipment, and can effectively ensure the overall crushing efficiency.

[0039] As a preferred embodiment, Figure 3 , 5 As shown in Figure 6, a gap is left between the coarse crushing section 201 and the fine crushing section 202 to form a screening channel 203, and a screen plate 204 is connected between the coarse crushing section 201 and the fine crushing section 202 to screen the ore flowing from the coarse crushing section 201 to the fine crushing section 202, and the screened ore is discharged from the screening channel 203, so that the ore with the crushed size meeting the requirements can be discharged in time to avoid congestion in the fine crushing section 202.

[0040] At the same time, the working surface of the movable jaw 3 is provided with a sink 301 corresponding to the sieve plate 204 to avoid squeezing the ore at this position and causing damage to the sieve plate 204, thereby ensuring the reliability of use. In addition, the side plate 102 is provided with an insertion port 105 corresponding to the position of the sieve plate 204, which is used to insert and pull out the sieve plate 204 through the insertion port 105. Among them, one end of the sieve plate 204 is fixedly connected to an end plate 206, and the end plate 206 is fixedly connected to a handle 207. The end plate 206 can be connected to the side plate 102 by hand screws, which is convenient for fixing the sieve plate 204. When disassembly is required, the sieve plate 204 can be directly pulled out by the handle 207, so as to facilitate the inspection and cleaning of the sieve plate 204, which greatly improves the convenience of use.

[0041] In addition, the base support 101 is provided with a first discharge port 103 and a second discharge port 104. The first discharge port 103 corresponds to the screening channel 203, so that the ore screened by the screen plate 204 is discharged through the screening channel 203 and the first discharge port 103, and the ore crushed by the movable jaw 3 and the fine crushing section 202 is discharged from the second discharge port 104. A guide plate can be installed on the inner wall of the second discharge port 104, so that the crushed ore can be accurately discharged through the second discharge port 104, avoiding the occurrence of residual accumulation in the gaps in the base support 101 due to the splashing of ore during crushing.

[0042] As another preferred embodiment, Figure 1 , 4 As shown in FIG. 6 , buffer baffles 5 are provided on opposite sides of the two side panels 102 , and the buffer baffles 5 are fixedly connected to two or four guide rods 501 . The side panels 102 are provided with through holes that are clearance-matched with the guide rods 501 , so that the guide rods 501 can movably intersperse with the side panels 102 through the through holes.

[0043] The guide rod 501 is sleeved with a spring 502, and the outer side surface of the side plate 102 is fixedly connected to the limiting bracket 503 by screws. The limiting bracket 503 is provided with a through hole that matches the gap with the guide rod 501, and one end of the spring 502 is against the limiting bracket 503. The guide rod 501 can be a stepped shaft structure, and the other end of the spring 502 is against the shoulder of the guide rod 501, thereby generating an axial thrust on the guide rod 501, which is used to push the buffer baffle 5 toward the inner side of the side plate 102.

[0044] When ore is poured between the fixed jaw 2 and the movable jaw 3, or when the ore hits the buffer baffle 5 during the crushing process, the spring 502 is compressed to reduce the impact and protect the side plate 102, thereby preventing the ore from damaging the side plate 102, thereby effectively ensuring the overall reliability and stability.
