TECHNICAL FIELD

[0001] The present application relates to the technical field of ore crushing, in particular to an ore crushing device with splash-proof function. BACKGROUND

[0002] In ore crushing processing, the screening of the crushed material is a key link that determines the overall production efficiency and product quality. The core of the screening process is how to efficiently and uniformly separate materials of different particle sizes, and ensure the long-term stable operation of the screening device. Traditional screening equipment, such as vibrating screen and drum screen, etc.

[0003] At present, in the screening process, the material is prone to accumulate and harden on the surface of the screen, causing the screen hole to be blocked. This not only sharply reduces the screening efficiency and processing capacity, but also requires frequent manual cleaning, which seriously affects the continuity of production, and has the problem of high energy consumption. The power transmission chain is long, the friction loss is large, the screening and crushing links often need to do work repeatedly, and the material transfer between equipment is frequent, resulting in a large amount of invalid energy consumption, and the overall energy efficiency is low. Secondly, the traditional screening mechanism adopts rigid connection and simple harmonic motion, the motion trajectory is single and the force cannot be adjusted, the dispersing effect on the material lumps is limited, and it is easy to cause over-crushing of brittle minerals. More importantly, this rigid motion mode directly transmits the huge impact load to the screen box and supporting structure, causing equipment fatigue, loose connecting parts, increased noise, and shortening the service life of the equipment. In addition, the grinding and particle size grading of ore crushing are usually carried out in two independent devices, which increases the energy consumption and dust pollution risk in the material transfer process. The single rotation of the grinding and crushing cannot form a multi-dimensional and multi-level composite force field in the grinding cavity, which limits its ability to crush different particle size materials, and reduces the uniformity and crushing efficiency of the final product.

[0015] 2. In this invention, the uniform rotational motion of the first motor in the swaying and turning assembly is transformed into a stable and efficient spatial oscillation of the turning frame. By utilizing the cooperation of the arc-shaped swaying rod, the T-shaped slider and the slide groove, the simple circumferential input is transformed into a composite motion of reciprocating sliding and oscillation of the arc-shaped swaying block within a defined track. This motion is further transmitted to one end of the turning frame through the arc-shaped swaying seat and the connecting rod, while the other end of the turning frame uses the fixed rotating rod as the fulcrum, forming a non-uniform, multi-track spatial oscillation. The swaying not only conforms to the gentle motion of natural material throwing, but also automatically adjusts the turning force and range according to the ore particle size and accumulation state, realizing a dynamic adaptive turning process, which significantly improves the uniformity and efficiency of ore screening inside the turning frame.

[0016] 3. In this invention, the oscillating frame in the oscillating and turning assembly effectively breaks up ore clumps and prevents material from directionally accumulating on the bottom surface of the turning frame, thereby completely preventing the problem of screen hole clogging. The turning amplitude and coverage of the turning surface of the turning frame, along with the significant flexibility and buffering characteristics of the turning action, greatly reduce the rigid impact and instantaneous load of the ore on the mechanical structure, improve the durability and operational stability of the equipment, and enhance the automation and operational continuity of the entire screening system. It not only optimizes screening efficiency and uniformity, but also achieves high-efficiency, low-wear, and long-life reliable operation through intelligent mechanical adjustment.

[0017] 4. In this invention, the oscillating and turning components work together with the pushing and processing components to synchronize the turning action with the scraping and feeding rhythm. Whenever the turning action causes the ore to fall through the screen holes to the bottom of the screening box, the reciprocating scraping of the discharge frame is immediately activated, like a robotic arm continuously and steadily pushing qualified fine materials to the collection channel. This achieves seamless connection between screening and collection in terms of time and space, significantly avoiding the retention and repeated grinding of fine materials at the bottom of the screening box, and ensuring the continuous operation of screening efficiency. The turning holes and sealing plug structure set on the turning frame allow large pieces of material that cannot pass through the turning frame to be discharged through the discharge bin door, effectively improving the utilization rate of raw materials and the particle size qualification rate of the final product.

[0018] 5. In this invention, the second motor in the interlaced grinding assembly drives the swing arm to perform planar composite motion. Through the linkage between the swing disk and the surrounding support rods, the power is synchronously transmitted to all grinding columns. This not only achieves synchronous driving and balanced force field distribution of multiple grinding units, but also causes each grinding column to drive the grinding base at the bottom to produce regular oscillation. The grinding racks on the edge of the grinding base continuously mesh with the central fixed interlaced gears, forming radial interlaced shearing forces to perform the first fine dissection of the ore. The grinding cone at the bottom of the grinding base and the grinding balls fixed at the bottom of the grinding box form axial rotational grinding pressure in relative motion, which deeply crushes the falling finer particles. They are naturally connected in vertical space, forming a three-dimensional composite grinding force field, which significantly improves grinding efficiency and product uniformity.

[0019] 6. In this invention, the drive motor synchronously drives all the interlaced triangular crushing blades through a single chain, enabling multiple sets of blades to form a coordinated shearing motion, significantly improving the single-pass crushing efficiency and avoiding energy waste caused by repeated crushing from the source. The first motor not only drives the tilting frame to perform reciprocating oscillating screening, but also synchronously drives the circular discharge frame to move horizontally through a gear and rack mechanism, automatically pushing qualified particles into the next process, achieving "one motor, two effects." This completely eliminates the need for separate motors for screening and discharge, significantly reducing the total installed power and standby energy consumption of the equipment. In the fine grinding stage, the second motor drives the swing arm, which synchronously drives multiple grinding columns through a set of planar linkage mechanisms. The grinding chassis revolves around a central point; simultaneously, it rotates on its own axis through the meshing of a rack and pinion with a fixed gear, forming a composite grinding motion that combines revolution and rotation. This multi-directional, coordinated grinding method, compared to traditional single-dimensional grinding, can refine ore in a shorter time and with more uniform force, thus significantly shortening the effective operating time of the motor and reducing energy consumption per unit output. Through power reuse and motion coupling, energy is concentrated for effective work, reducing energy loss in the transmission process and motor idling. This achieves a leap from localized high efficiency to system-wide energy saving, enabling the equipment to perform high-intensity crushing and grinding tasks while having lower operating energy consumption and better economic performance.

[0026] Referring to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , the inside of the screening box 30 is provided with a swing turnover assembly, the swing turnover assembly is used for screening and filtering the primary crushed ore, the turnover frame 37 provided in the swing turnover assembly turns over the crushed ore, the turnover frame 37 is movably arranged at the bottom center of the crushing box 10, the bottom of the turnover frame 37 is uniformly provided with a plurality of holes for screening the crushed ore, the swing turnover assembly further includes an arc-shaped swing rod 45 and an arc-shaped swing seat 40, the motor bottom plate 31 is fixedly installed at the inner bottom of the screening box 30, the first motor 32 is fixedly installed at the top center of the motor bottom plate 31, the arc-shaped swing rod 45 is fixedly installed at the output end of the first motor 32 through the rotating shaft 33, the arc-shaped swing rod 45 is driven by the first motor 32 to stably rotate, the fixed rotating rod 35 is movably connected inside the screening box 30, the arc-shaped connecting plate 36 is fixedly installed at the center of the fixed rotating rod 35, and the arc-shaped connecting plate 36 is fixedly installed at the bottom of the turnover frame 37.

[0027] Referring to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8An arc-shaped connecting rod 38 is fixedly installed at the bottom of the flipping frame 37 at the end away from the arc-shaped connecting plate 36, and the arc-shaped connecting rod 38 is fixedly installed on the top of the arc-shaped rocker seat 40. The arc-shaped rocker rod 45 is movably connected to the arc-shaped rocker block 43 through the support pivot 44, and the arc-shaped rocker block 43 moves inside the arc-shaped rocker seat 40. A T-shaped groove 41 is provided on the inner side of the arc-shaped rocker seat 40, and a T-shaped slider 42 is slidably connected in the T-shaped groove 41. The T-shaped slider 42 is fixedly installed on the arc-shaped rocker block 43. The arc-shaped rocker block 43 moves back and forth stably and smoothly under the action of the T-shaped groove 41 and the T-shaped slider 42.

[0028] See Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 After the first motor 32 located at the bottom of the screening box 30 starts, its output end drives the rotating shaft 33 to perform uniform circular motion with the fixed arc-shaped rocking rod 45. The arc-shaped rocking rod 45 drives the arc-shaped rocking block 43 through the supporting rotating shaft 44 at its end. The T-shaped slider 42 fixed on the arc-shaped rocking block 43 is constrained to slide in the T-shaped groove 41 inside the arc-shaped rocking seat 40, thus transforming it into a compound motion of reciprocating sliding and swinging of the arc-shaped rocking block 43 in the T-shaped groove 41. The power of the motion is transmitted to the arc-shaped connecting rod 38 fixed to it through the arc-shaped rocking seat 40, thereby pushing one end of the flipping frame 37. At the same time, the other end of the flipping frame 37 is fixed to the fixed rotating rod 35 through the arc-shaped connecting plate 36, forming a rotation fulcrum. Therefore, Driven continuously by the first motor 32, the turning frame 37 does not simply rotate or move in a straight line, but rather forms a non-uniform, complex spatial oscillation, continuously turning over the material that has fallen to the upper layer of the screening box 30 after crushing. This transforms the simple rotational input into a turning motion that is more suitable for loosening and screening ore, resulting in a better motion trajectory. It can effectively break up ore clumps and prevent the bottom holes of the turning frame 37 from clogging. In addition, the turning frame 37 adopts a simple structure with a large degree of freedom of movement centered on the fixed rotating rod 35, ensuring the amplitude and flexibility of the turning action of the turning frame 37, reducing the rigid impact of ore on the structure of the turning frame 37, and achieving a highly efficient, gentle, and wide-coverage turning effect. This significantly improves the uniformity and efficiency of ore screening inside the turning frame 37.

[0029] See Figure 5 , Figure 6 , Figure 7 and Figure 8The oscillating and flipping assembly includes a motor base plate 31 and a fixed rotating rod 35. A pushing and discharging assembly is provided on the fixed rotating rod 35. The pushing and discharging assembly is used to push the ore screened by the flipping frame into the grinding box 70. The U-shaped discharge frame 57 in the pushing and discharging assembly moves horizontally back and forth at the bottom of the screening box 30. The pushing and discharging assembly includes a limiting base 50 and a supporting gear 54. The limiting base 50 is fixedly installed at both ends of the motor base plate 31. A fixed slide groove 51 is opened at the top of the limiting base 50. A fixed slider 52 is slidably connected in the fixed slide groove 51. A rack plate 53 is fixedly installed between the tops of the fixed sliders 52. The supporting gear 54 is fixedly installed at both ends of the fixed rotating rod 35, and the supporting gear 54 is movably meshed with the rack plate 53. A fixed hole 55 is opened at the center of the limiting base 50. The rack plate 53 moves back and forth stably and smoothly under the action of the fixed slide groove 51 and the fixed slider 52.

[0030] See Figure 5 , Figure 6 , Figure 7 and Figure 8 An arc-shaped support rod 56 is fixedly installed at the bottom center of the rack plate 53, and the arc-shaped support rod 56 matches the size of the fixed hole 55. The arc-shaped support rod 56 moves through the fixed hole 55. The U-shaped discharge frame 57 is fixedly installed at the bottom end of the arc-shaped support rod 56. The bottom of the screening box 30 is provided with a screening hole 58. The U-shaped discharge frame 57 moves at the top center of the screening hole 58. The flipping frame 37 is provided with a flipping hole 34 at the bottom of the end away from the motor base plate 31, and a sealing plug is provided inside the flipping hole 34. The screening box 30 is provided with a discharge chamber door 39 at the end away from the motor base plate 31. The crushed ore in the flipping frame 37 is discharged to the outside of the discharge chamber door 39 through the flipping hole 34.

[0031] See Figure 5 , Figure 6 , Figure 7 and Figure 8When the first motor 32 drives the tilting frame 37 to reciprocate, the fixed rotating rod 35, which is fixed to the bottom of the tilting frame 37, rotates stably in both directions. The support gears 54 at both ends of the fixed rotating rod 35 convert this rotational motion into precise horizontal reciprocating linear motion of the rack plate 53 meshing with it within the fixed slide groove 51 of the limiting base 50. The motion of the rack plate 53 is transmitted to the U-shaped discharge frame 57 at the end through the arc-shaped support rod 56 at its bottom, causing it to reciprocate and scrape synchronously above the screening holes 58 at the bottom of the screening box 30, thus cleaning the U-shaped discharge frame 57. The scraping action is naturally synchronized with the turning rhythm of the turning frame 37. The qualified ore that is turned and dispersed and passes through the screen holes can be immediately collected by the reciprocating U-shaped discharge frame 57 and pushed to the collection area, avoiding the accumulation of ore at the bottom of the screening box 30 and maintaining the continuous high efficiency of screening. Through the turning holes 34 with sealing plugs set on the turning frame 37, large pieces of material can be directly discharged quickly through the discharge bin door 39 without passing through the screen. The large pieces of ore that are stuck inside the turning frame 37 are put back into the feed hopper 18 and enter the crushing box 10 for further crushing.

The swing arm 62 is movably connected to a swing disk 63. Grinding columns 71 are evenly connected around the top of the grinding box 70. A first support rod 72 is fixedly installed on the top of the grinding column 71. Several second support rods 73 are fixedly installed around the swing disk 63, and the first support rod 72 and the second support rod 73 are movably connected.

An arc-shaped discharge hood 80 is fixedly installed at the bottom of the grinding box 70.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 and Figure 10 After screening, the fine material enters the grinding chamber 70 through the guide chamber 81 and guide pipe 82. The second motor 61 is started, driving the swing arm 62 to rotate, which in turn drives the swing arm 62 and the swing disk 63 to perform a planar compound motion. The swing disk 63 is movably connected to the first support rod 72 fixed on the top of several grinding columns 71 through the second support rod 73 around its perimeter, thereby transmitting power to all grinding columns 71. The grinding columns 71 synchronously drive the grinding base 74 at the bottom to rotate. The grinding base 74 meshes with the interlaced gear 76 fixed at the center of the bottom of the grinding chamber 70. The grinding rack 75 on the edge of the grinding base 74 meshes with the interlaced gear. 76 meshes, producing lateral, staggered shearing and grinding of the ore; simultaneously, the grinding cone 77 at the bottom of the grinding chassis 74 moves relative to the grinding ball 78 fixed at the bottom of the grinding box 70, applying rotational crushing to the ore. Through the synergistic effect of this composite force field, efficient energy conversion and utilization are achieved. Multi-dimensional grinding driven by a single motor significantly reduces the power consumption per unit output. Under the action of these two composite grinding forces, the ore is thoroughly crushed, and the ore material that finally meets the fineness requirements falls through the base holes 79 around the bottom of the grinding box 70, is collected and discharged uniformly through the arc-shaped discharge hood 80, and completes the requirements from ore crushing.

[0034] Working principle: Ore is injected through the feed hopper 18 at the top of the crushing box 10. The drive motor 14 located at the bottom of the crushing box 10 is started. The output end of the drive motor 14 drives the first gear 15 to rotate. The first gear 15 drives the second gear 16, which is fixed on one of the rotating gears 13, to move synchronously through the chain 17. Since the rotating gears 13 at the ends of the two sets of triangular crushing blades 11 mesh with each other, and the bottom of the blades is stably supported by a dedicated blade base 12, the power of the rotating gears 13 is synchronously transmitted to the two sets of triangular crushing blades 11, so that the adjacent pair of triangular blades move stably. The reverse rotational motion creates a continuous and powerful shearing and tearing force between the two sets of triangular crushing blades 11, thereby efficiently crushing the ore. To prevent material splashing during the crushing process, a splash guard assembly is installed at the top of the crushing box 10. The main body of the splash guard assembly is an arc-shaped cover plate 20 covering the triangular crushing blades 11. A set of arc-shaped splash guard strips 21 with decreasing diameters are installed at the end of the arc-shaped cover plate 20 near the feed hopper 18. These arc-shaped splash guard strips 21 form a stepped barrier, which can effectively block and guide the splashed ore particles back to the working area, ensuring a clean and safe working environment.

[0035] After initial crushing, the ore falls into the screening box 30 below. Then, the first motor 32 on the motor base plate 31 inside the screening box 30 is activated. The first motor 32 drives the arc-shaped rocker arm 45 to perform circular motion. The arc-shaped rocker arm 45 slides within the T-shaped groove 41 inside the arc-shaped rocker seat 40 via the arc-shaped rocker block 43 at its end, thus converting the circular motion into the reciprocating rocking motion of the arc-shaped rocker seat 40 and the arc-shaped connecting rod 38 rigidly connected to it. The arc-shaped connecting rod 38 directly drives the tilting frame 37 to perform synchronous rocking motion. Specifically, the end of the arc-shaped rocker arm 45 is movably connected to the arc-shaped rocker block 43 via a support shaft 44. The arc-shaped rocker block 43 is nested inside the arc-shaped rocker seat 40, and the T-shaped slider 42 fixed on the arc-shaped rocker block 43 is precisely... The T-shaped groove 41 is embedded in the inner side of the arc-shaped rocker seat 40. So when the arc-shaped rocker arm 45 makes a circular motion, it will drive the arc-shaped rocker block 43 to move. However, since the T-shaped slider 42 is restricted to sliding in the T-shaped groove 41, the circular motion of the arc-shaped rocker arm 45 is forced into a precise reciprocating rocking motion with a limited arc around the fixed rotating rod 35. The entire turning frame 37 swings through the arc-shaped connecting plate 36 and the fixed rotating rod 35. This swinging motion can provide more stable guidance, withstand greater lateral force, ensure controllable motion trajectory, reduce shaking and wear, and continuously turn over and screen the ore material in the turning frame 37, so that qualified particles after preliminary crushing can be separated through the holes at the bottom of the turning frame 37.

[0036] The swaying motion of the tilting frame 37, via the arc-shaped connecting plate 36 at its bottom, drives the fixed rotating rod 35 to reciprocate. The support gears 54 at both ends of the fixed rotating rod 35 then rotate stably. These support gears mesh and drive the rack plate 53 below to perform precise horizontal reciprocating linear motion along the fixed slide groove 51 of the limiting base 50. The arc-shaped support rod 56 at the bottom of the rack plate 53 ultimately drives the circular discharge frame 57 to reciprocate horizontally in sync. The qualified ore, after being screened by the tilting frame 37, settles at the bottom of the screening box 30. The particles, which are pushed smoothly from the screening holes 58 into the channel leading to the grinding box 70 by the horizontally reciprocating U-shaped discharge frame 57 like a scraper, are separated from the coarse material that fails to pass through the screening and remain in the turning frame 37. The turning frame 37 has a turning hole 34 at the bottom of the end away from the motor base plate 31, and a sealing plug is provided inside. When the turning frame 37 swings to an inclined downward angle, the sealing plug in the turning hole 34 opens, and the coarse material is discharged through the turning hole 34 to the discharge bin door 39, realizing the efficient automatic and physical separation of coarse and fine materials.

[0037] The screened fine material enters the grinding chamber 70 through the guide chamber 81 and guide pipe 82. The second motor 61 is started, driving the swing arm 62 to rotate, which in turn causes the swing arm 62 and the swing disk 63 to perform a planar compound motion. The swing disk 63 is movably connected to the first support rod 72 fixed on the top of several grinding columns 71 through the second support rod 73 around its perimeter, thereby transmitting power to all grinding columns 71. The grinding columns 71 synchronously drive the grinding base 74 at the bottom to rotate. The grinding base 74 and the interlocking gear 74 fixed at the center of the bottom of the grinding chamber 70 are connected to the grinding base 74. 6. The grinding rack 75 on the edge of the grinding chassis 74 meshes with the interlaced gear 76, producing lateral interlaced shearing and grinding of the ore; at the same time, the grinding cone 77 at the bottom of the grinding chassis 74 moves relative to the grinding ball 78 fixed at the bottom of the grinding box 70, applying rotational crushing to the ore. Under the action of these two combined grinding forces, the ore is completely crushed, and the ore material that finally meets the fineness requirements falls through the base holes 79 around the bottom of the grinding box 70, is collected and discharged uniformly by the arc-shaped discharge hood 80, and completes the requirements of ore crushing.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
