Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of ore mining equipment, in particular to an ore crushing equipment. BACKGROUND

[0002] In the mining of mines and mines, the mined ore needs to be crushed, and crushing equipment needs to be used. There are many types of existing crushing equipment.

[0003] For example, Chinese invention CN117463445B discloses an ore crushing equipment. By driving the corresponding crushing rollers to rotate towards each other, the ore falls between the oppositely arranged crushing rollers and is subjected to first crushing by the extrusion of multiple crushing rollers. The large first crushed stones will roll along the inclined screening plate to the space between the first extrusion plate and the second extrusion plate. The second extrusion plate is also moved up and down during the reciprocating movement of the screening plate, thereby extruding and crushing the large first crushed stones, i.e. secondary crushing.

[0004] However, in the above-mentioned prior art, the ore is crushed by the engagement of the two crushing rollers. Due to the high hardness of the ore, the ore may be stuck by the engagement of the two crushing rollers, or the ore may be too large to be engaged by the two crushing rollers, thereby resulting in poor overall crushing effect and crushing efficiency. SUMMARY

[0005] The present application aims to provide an ore crushing equipment. By arranging the working surface of the moving jaw to be inclined downward, and by reciprocating the moving jaw up and down and cooperating with the fixed jaw, the ore is crushed, thereby solving the problem of poor overall crushing effect and crushing efficiency.

[0006] To solve the above technical problems, the present application is realized by the following technical scheme:

[0007] The present application is an ore crushing equipment, which comprises a frame, a fixed jaw connected to the frame, a moving jaw connected to the frame in a sliding manner, and a driving mechanism connected to the moving jaw in a transmission manner. The fixed jaw comprises a coarse crushing section and a fine crushing section, and the included angle between the working surface of the coarse crushing section and the vertical direction is greater than the included angle between the working surface of the fine crushing section and the vertical direction. The working surface of the moving jaw is arranged to be inclined downward and parallel to the working surface of the fine crushing section, so that the distance between the moving jaw and the coarse crushing section gradually decreases and is greater than the distance between the moving jaw and the fine crushing section. The moving jaw is driven to reciprocate up and down by the driving mechanism, and cooperates with the fixed jaw to crush the ore.

[0008] As a preferred embodiment of the present invention, a gap is left between the coarse crushing section and the fine crushing section to form a screening channel, and a screen plate is connected between the coarse crushing section and the fine crushing section for screening the ore flowing from the coarse crushing section to the fine crushing section, so that the screened ore is discharged from the screening channel.

[0009] As a preferred embodiment of the present invention, the working surface of the moving jaw is provided with a settling groove corresponding to the screen plate to avoid squeezing the ore at this position and causing damage to the screen plate.

[0010] As a preferred embodiment of the present invention, the working surface of the movable jaw is provided with broken teeth evenly distributed.

[0011] As a preferred embodiment of the present invention, the working surface of the fine crushing section is uniformly provided with broken fine teeth, and the cross-section of the broken fine teeth is smaller than that of the crushing teeth, and the distribution density is greater than that of the crushing teeth.

[0012] As a preferred embodiment of the present invention, the frame includes a base support, two side plates connected to the base support, a fixed jaw fixedly connected to the base support, and a movable jaw slidably connected between the two side plates.

[0013] As a preferred technical solution of the present invention, the base support is provided with a first discharge port and a second discharge port, wherein the first discharge port corresponds to the screening channel, and the ore crushed by the moving jaw and the fine crushing section is discharged from the second discharge port.

[0014] As a preferred embodiment of the present invention, the driving mechanism includes an eccentric shaft rotatably connected between two side plates, and a drive motor that is drively connected to the eccentric shaft is fixedly connected between the two side plates; the eccentric shaft is rotatably connected to a plurality of fixed bushings, and each of the two fixed bushings is fixedly connected to a slider, which is slidably connected to the moving jaw through the slider, and the sliding direction of the slider is horizontal.

[0015] As a preferred embodiment of the present invention, buffer baffles are provided on opposite sides of the two side plates. Several guide rods are fixedly connected to the buffer baffles, and the guide rods are movably inserted into the side plates. Springs are sleeved on the guide rods, and limit brackets are fixedly connected to the outer side of the side plates. The limit brackets have through holes that fit with the guide rods with clearance, and one end of the spring abuts against the limit brackets to push the buffer baffles toward the inner side of the side plates.

[0016] As a preferred embodiment of the present invention, the side plate is provided with an insertion port corresponding to the position of the sieve plate, for inserting and pulling the sieve plate through the insertion port; wherein, one end of the sieve plate is fixedly connected to an end plate, and the end plate is fixedly connected to a handle.

[0017] The present invention has the following beneficial effects:

[0018] In this invention, the working surface of the moving jaw is inclined downwards and parallel to the working surface of the fine crushing section. This causes the distance between the moving jaw and the coarse crushing section to gradually decrease and become greater than the distance between the moving jaw and the fine crushing section. The moving jaw is driven to move up and down reciprocally by a drive mechanism and cooperates with the fixed jaw to crush the ore, avoiding the occurrence of ore jamming. At the same time, the gravity of the moving jaw itself is used to improve the crushing effect on the ore when moving downwards, thereby improving the overall crushing efficiency.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0031] Please see Figure 1 , 2 As shown in Figure 5, the present invention is an ore crushing device, including a frame 1, a fixed jaw 2 fixedly connected to the frame 1, a movable jaw 3 slidably connected to the frame 1, and a drive mechanism connected to the movable jaw 3 for transmission.

[0032] Specifically, the frame 1 includes a base support 101 and two side plates 102 connected to the base support 101. The base support 101 is equipped with a mounting support structure, which can be cast. The base support 101 is arched to facilitate the installation of a conveying device below it. The fixed jaw 2 is fixedly connected to the mounting support structure of the base support 101, and the movable jaw 3 is slidably connected between the two side plates 102 via a guide rail slider assembly.

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

[0034] The eccentric shaft 4 is rotatably connected to two or more fixed bushings 402. In this embodiment, two are shown in the figure as an example. Both fixed bushings 402 are fixedly connected to sliders. The back of the movable jaw 3 can be provided with a sliding groove, and the slider is slidably connected to the sliding groove of the movable jaw 3. The sliding direction of the slider is horizontal, so that 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 rotation of the eccentric shaft 4 causes the fixed bushings 402 to move in the up and down direction, the slider will drive the movable jaw 3 to move up and down. Thus, through the rotation of the eccentric shaft 4, the movable jaw 3 only produces 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 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 downwards, and the angle β with the vertical direction is 20° to 45°. The angle α between the working surface of the coarse crushing section 201 and the working surface of the movable jaw 3 is 15° to 30°. The movable jaw 3 is driven to move up and down reciprocally by the drive mechanism 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 down to the fine crushing section 202. At this time, the movable jaw 3 and the fine crushing section 202 cooperate. Due to the smaller distance between them, the ore is further crushed.

[0037] Among them, the working surface of the moving jaw 3 is evenly provided with crushing teeth 302. The crushing effect of the ore can be improved by squeezing the ore with crushing teeth 302. The working surface of the fine crushing section 202 is evenly provided with broken fine teeth 205. 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 that of the crushing teeth 302. By using smaller and denser crushing teeth 302, the further crushing effect of the ore can be improved, ensuring the overall crushing effect.

[0038] By setting the moving jaw 3 parallel to the working surface of the fine crushing section 202, the moving jaw 3 moves up and down reciprocally, creating a pressing and kneading effect on the ore between it and the fine crushing section 202. This is more conducive to crushing the ore and improving the crushing effect. Furthermore, since the moving jaw 3 moves up and down reciprocally, it can effectively prevent the ore from jamming the equipment and effectively ensure the overall crushing efficiency.

[0039] As a preferred embodiment, such as 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. 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 to discharge the screened ore through the screening channel 203. This allows the ore that meets the crushing size requirements to be discharged in a timely manner, avoiding congestion in the fine crushing section 202.

[0040] Meanwhile, the working surface of the moving jaw 3 is provided with a settling groove 301 corresponding to the screen plate 204 to prevent the ore from being squeezed at this position and damaged, thus ensuring the reliability of use. Furthermore, the side plate 102 is provided with an insertion port 105 corresponding to the position of the screen plate 204, for inserting and removing the screen plate 204 through the insertion port 105. One end of the screen plate 204 is fixedly connected to an end plate 206, and a handle 207 is fixedly connected to the end plate 206. The end plate 206 can be connected to the side plate 102 by a hand-tightening screw, facilitating the fixing of the screen plate 204. When disassembly is required, the screen plate 204 can be directly pulled out through the handle 207, thus facilitating the inspection and cleaning of the screen plate 204 and greatly improving the convenience of use.

[0041] In addition, the base support 101 has 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, while the ore crushed by the moving jaw 3 and the fine crushing section 202 is discharged through 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 accumulation of residual ore in the gaps inside the base support 101 due to ore splashing during crushing.

[0042] As another preferred implementation, such as Figure 1 , 4 As shown in Figure 6, buffer baffles 5 are provided on opposite sides of the two side plates 102. Two guide rods 501 are fixedly connected to the buffer baffles 5. The side plates 102 are provided with through holes that fit the guide rods 501 with a clearance, so that the guide rods 501 can move and insert between the side plates 102 through the through holes.

[0043] A spring 502 is fitted onto the guide rod 501. A limit bracket 503 is fixedly connected to the outer side of the side plate 102 by screws. The limit bracket 503 has a through hole that fits the guide rod 501 with clearance. One end of the spring 502 abuts against the limit bracket 503. The guide rod 501 can be a stepped shaft structure. The other end of the spring 502 abuts 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 inside of the side plate 102.

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