Description

Technical Field

[0001] This utility model belongs to the field of sorting device technology, specifically relating to a crushed stone sorting device for mining. Background Technology

[0002] In the mining and processing of mineral resources, crushed ore typically needs further classification based on particle size to meet the requirements of subsequent smelting, transportation, or processing. Existing crushing and sorting equipment generally employs a vibrating screen structure. A vibrating mechanism drives the screen plate to generate periodic vibrations, causing the ore to roll on the screen surface and automatically fall according to differences in aperture size, thus achieving particle size classification. To accommodate different types of ore and variations in particle size, the screen plate usually needs to be disassembled or replaced according to production requirements.

[0003] However, existing ore screening equipment still has many shortcomings in practical use. For example, some traditional equipment typically has a single-piece screen plate structure, which requires the entire screen plate to be replaced if a certain area is damaged, resulting in high maintenance costs. The screen plate replacement structure of some equipment is relatively complex, requiring the disassembly of multiple fasteners, which is time-consuming and not conducive to rapid production adjustments. In addition, the tilt angle adjustment mechanism of some existing screening equipment is cumbersome, requiring the disassembly of multiple parts during adjustment, making it difficult to promptly change the rolling speed and screening efficiency of the ore under different ore particle size and flow rate conditions.

[0004] Meanwhile, when there are significant variations in the type or particle size distribution of the ore, screening operations usually require replacing screen plates with different apertures or adjusting the screen plate inclination angle to change the screening speed. However, most existing equipment lacks convenient and quick screen plate disassembly and assembly structures and reasonable adjustable angle mechanisms, resulting in low efficiency in production line debugging and switching, which is not conducive to improving the continuity and stability of ore sorting. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a mining crushing and sorting device that facilitates quick assembly and disassembly of the screen plate, makes it easier to adjust the screening speed according to changes in ore particle size, and has lower maintenance costs. This solves specific problems such as high overall screen plate replacement costs, inconvenient screen plate angle adjustment, and inconvenient maintenance after screen plate damage, thereby improving ore sorting efficiency and equipment adaptability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A crushed stone sorting device for mining includes a vibrating screen body, which includes a U-shaped shell and two screen plates arranged inside the shell. The inner side of the shell is also provided with two support frames for clamping the screen plates.

[0008] The sieve plate is inserted and secured to the support frame from right to left, and a baffle is detachably installed at the right end of the housing;

[0009] The sieve plate includes a support plate, on which multiple evenly arranged perforated plates are laid, and the perforated plates are detachably fixed to the support plate.

[0010] The right end of the support frame is rotatably installed inside the housing, and the left end of the support frame can be adjusted by swinging up and down. Both the front and rear sides of the housing are equipped with locking mechanisms to lock and fix the support frame after adjusting the swing angle.

[0011] Furthermore, two guide grooves, one upper and one lower, are fixed on the left side of the housing, and a discharge pipe is provided on the lower side of the housing.

[0012] Furthermore, locking blocks are fixed on the front and rear side walls of the right port of the housing, and vertical opening slots are provided on the locking blocks, with the lower edge of the baffle locked in the opening slots.

[0013] Furthermore, the support frame is designed as a U-shape with an opening to the right, and the front and rear side walls inside the support frame are provided with slots. Adjustment shafts and rotating shafts are detachably fixed on the front and rear sides of the support frame near the left and right ends, respectively.

[0014] Furthermore, the support plate includes a frame, with several struts arranged in a front-to-back pattern fixed on the inner side of the frame, and protruding brackets fixed on both the front and back sides of the frame.

[0015] Furthermore, several positioning posts arranged horizontally are fixed on the upper surface of the frame near the front and rear sides, and several clips are also fixed on the upper surface of the frame near the front and rear sides.

[0016] Furthermore, the upper surface of the perforated plate has several positioning holes near the front and rear sides, and the front and rear edges of the perforated plate have snap grooves.

[0017] Furthermore, the locking mechanism includes a locking block fitted onto the adjusting shaft, with locking screws threaded onto both ends of the locking block, and the adjusting shaft is hung on the locking block using a mounting plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Existing stone sorting equipment generally suffers from complex disassembly and assembly processes for screen plate replacement, and the need to replace the entire screen plate when it is damaged, resulting in high maintenance costs and low production adjustment efficiency. This device addresses these issues by incorporating two detachable screen plate structures inside the housing. Both screen plates are supported by support plates and are composed of multiple independent perforated plates, allowing for individual replacement of the perforated plates based on their condition, thus avoiding the need for the entire screen plate to be scrapped. The structure of the screen plates being inserted into the support frame from right to left clearly defines the disassembly and assembly path, allowing for direct screen plate replacement by removing the baffles. This effectively solves the technical problems of high maintenance costs and low disassembly and assembly efficiency associated with existing screen plate structures.

[0020] Existing equipment struggles to adjust screening speed and rolling angle when processing different types and sizes of ores, limiting its adaptability to various operating conditions. This new device utilizes a rotating mounting structure on the right end of the support frame, allowing it to swing up and down around a pivot axis. A locking mechanism, through an adjusting shaft and locking screws, creates a stable angle lock, enabling rapid adjustment and subsequent fixation of the support frame after loosening. This allows for rapid changes in the screen plate angle. This structure enables flexible control of the screening speed based on differences in ore particle size, effectively solving the problems of complex angle adjustment and inconvenient production switching in existing equipment.

[0021] Existing crushing and grading equipment suffers from problems such as mixing of materials of different particle sizes, uneven discharge, or blockages in its material discharge structure. This device addresses these issues by installing corresponding upper and lower guide chutes on the left side of the casing, which match the upper and lower screen plates respectively. This allows large and medium-sized ore particles to be discharged independently along their respective guide paths. A discharge pipe at the bottom of the casing is used to transport the finest ore, ensuring a clearly segmented and non-interfering discharge process. This improves grading accuracy, prevents material accumulation, and increases material discharge efficiency.

[0022] Existing vibrating screen equipment generally suffers from slow assembly and disassembly, and the baffle structure is loose and prone to falling off. This device achieves rapid insertion and removal of the baffle through a combination of locking blocks and opening slots. This allows the baffle to be stably locked into the opening slot in the installation state and can be directly pulled out in the disassembly state, significantly improving the efficiency of baffle assembly and disassembly. At the same time, it keeps the baffle stable and prevents it from falling off when the equipment vibrates, thus solving the practical problems of complex baffle structure and inconvenient maintenance.

[0023] Existing screen plate support structures are cumbersome in terms of assembly and positioning, and installation accuracy is difficult to guarantee. This device adopts a U-shaped support frame, which provides sliding positioning for the screen plate through the grooves on the front and rear side walls. At the same time, the adjusting shaft and rotating shaft can be quickly assembled through the threaded head structure, making the assembly of the vibrating screen body simpler and smoother. This structure effectively improves the overall assembly accuracy, avoids screen plate deviation during operation, and improves screening stability. Attached Figure Description

[0033] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a crushed stone sorting device for mining includes a vibrating screen body. The vibrating screen body includes a U-shaped shell 1 and two upper and lower screen plates 2 disposed inside the shell 1. The inner side of the shell 1 is also provided with two upper and lower support frames 6 for clamping the screen plates 2.

[0035] In the ore sorting process, existing screening devices generally suffer from problems such as difficulty in replacing screen plates and fluctuations in screening efficiency with changes in ore particle size. Especially when processing ores of different particle sizes, the disassembly and assembly of the upper and lower screen plates is cumbersome, leading to low production adjustment efficiency. This structure, by setting two screen plates 2 inside the shell 1 and securing them with a support frame 6, allows the screen plates 2 to be stably positioned along the arrangement direction inside the shell 1. The U-shaped shell 1 forms a closed ore discharge space during vibrating screening, effectively preventing ore from scattering outwards during vibration. The upper and lower screen plates 2, when the ore is processed... After entering the housing 1, the belt conveyor sequentially screens the ore, causing large particles to remain on the upper screen plate 2 and be discharged through the upper guide chute 5. Medium particles are screened on the lower screen plate 2 and discharged through the lower guide chute 5. The finest particles fall to the bottom of the housing 1 and are discharged through the discharge pipe 12. This solves the problems of insufficient screening and unclear grading in existing devices, and realizes the functions of continuous screening and multi-stage sorting. The clamping method of the support frame 6 on the screen plate 2 improves the efficiency of screen plate assembly and disassembly, which is conducive to the adaptation and adjustment of the screen plate aperture according to different ore particle sizes, significantly improving the adaptability and flexibility of the equipment.

[0036] The sieve plate 2 is inserted and secured to the support frame 6 from right to left, and a baffle 3 is detachably installed at the right end of the housing 1;

[0037] In existing screening equipment, the insertion and removal direction of the screen plate is restricted and the baffle structure is inconvenient to disassemble, which requires the disassembly of multiple sets of fixing parts when maintaining or replacing the screen plate, resulting in low operating efficiency. This structure adopts the method of inserting the screen plate 2 from right to left, so that the screen plate 2 can slide into the installation position inside the housing 1 along the direction of the support frame 6, thereby reducing the jamming phenomenon during the installation process. The baffle 3 set at the right end of the housing 1 can be quickly opened through a detachable structure. In the assembled state, the baffle 3 blocks the sliding path of the screen plate 2 to prevent the screen plate 2 from falling out. In the disassembled state, it can immediately provide space for the replacement of the screen plate 2, so that the screen plate 2 can be quickly removed or reinstalled during maintenance, effectively solving the problems of difficult screen plate replacement and disassembly and high time cost in existing equipment.

[0038] The sieve plate 2 includes a support plate 22, on which a plurality of evenly arranged perforated plates 21 are laid, and the perforated plates 21 are detachably fixed on the support plate 22.

[0039] Existing integral screen plate structures require replacement of the entire screen plate after damage to a local perforation area, which is not only wasteful of materials but also has high maintenance costs. The support plate 22 provides overall support rigidity through the frame 221 and the internal front and rear arranged support rods 222. The perforated plates 21 are laid on the support plate 22 in a uniform distribution and are detachably fixed by the fastening groove 212-clamping plate 224 structure, so that the perforated plates 21 can be replaced individually according to the wear condition, thereby solving the problem of high maintenance costs of traditional screen plate structures. The independent setting of multiple perforated plates 21 makes it easy to adjust the aperture combination according to the difference in ore particle size, so that the screen plate 2 can maintain ideal screening efficiency under different working conditions, further improving the adaptability of the sorting device.

[0040] The right end of the support frame 6 is rotatably installed inside the housing 1, and the left end of the support frame 6 can be adjusted by swinging up and down. Both the front and rear sides of the housing 1 are provided with locking mechanisms 4 for locking and fixing the support frame 6 after adjusting the swing angle.

[0041] In ore screening equipment, the screen plate inclination angle has a significant impact on the ore rolling speed and screening efficiency. In existing structures, the screen plate inclination angle adjustment is complex and difficult to adjust in a timely manner under different ore particle size conditions. The right end of the support frame 6 is rotatably connected inside the housing 1 through a rotating shaft 63, allowing the left end of the support frame 6 to swing up and down around the rotating shaft 63. When it is necessary to adjust the screening speed, the operator can loosen the locking screw 41 on the locking block 42 in the locking mechanism 4, so that the locking block 42 is unlocked along the adjusting shaft 61, thereby allowing the support frame 6 to change angle. After the support frame 6 is adjusted to the target angle, the locking screw 41 is tightened again to fix the position and realize the rapid adjustment of the screening speed. This structure solves the problem of cumbersome angle adjustment in existing equipment and improves the flexibility and adaptability of the screening device.

[0042] like Figure 2 As shown, two guide grooves 5 are fixed on the left side of the housing 1, and a discharge pipe 12 is provided on the lower side of the housing 1.

[0043] Existing screening devices are prone to blockage or grade confusion when the material discharge path after screening is not designed properly. In this structure, the upper guide chute 5 and the lower guide chute 5 are respectively arranged with the upper screen plate 2 and the lower screen plate 2, so that ores of different particle sizes can be smoothly discharged through their own independent guide paths after screening. The discharge pipe 12 at the bottom of the shell 1 is used to discharge the smallest particle size ore, so that the material flow direction is clear and continuous, thereby effectively avoiding material accumulation and mixing, and improving the accuracy of grading and discharge efficiency.

[0044] like Figure 2 As shown, a locking block 13 is fixed on the front and rear side walls of the right port of the housing 1. The locking block 13 has a vertical opening groove, and the edge of the lower end of the baffle 3 is locked in the opening groove.

[0045] Existing baffle installation structures generally involve complicated fixing methods and time-consuming disassembly; the locking block 13 forms a sliding locking structure through a vertical opening groove, which allows the baffle 3 to be quickly inserted or pulled out along the opening groove direction, solving the problem of low disassembly and assembly efficiency of existing baffles; this structure also ensures that the baffle 3 can be stably positioned when the vibrating screen is working, preventing the baffle 3 from falling off due to vibration and ensuring the operational safety of the screen plate 2.

[0046] like Figure 4 As shown, the support frame 6 is U-shaped with an opening to the right, and the front and rear side walls of the support frame 6 are provided with slots 62. The adjustment shaft 61 and the rotating shaft 63 are detachably fixed on the front and rear sides of the support frame 6 near the left and right ends, respectively. The adjustment shaft 61 and the rotating shaft 63 are fixed to the support frame 6 by threaded heads for installation and support, which makes the installation of the support frame 6 more convenient and quick, and also makes the assembly of the entire vibrating screen body more convenient.

[0047] Existing screen plate support structures require multi-point positioning during installation or disassembly, resulting in complex structures and low maintenance efficiency. The U-shaped support frame 6 reduces installation interference space through left and right opening structures, and the slot 62 provides precise sliding positioning for the screen plate 2. The adjusting shaft 61 is used for angle adjustment, and the rotating shaft 63 is used for rotation support. Both are fixed by threaded head structures, making the installation and replacement process simpler. The overall structure improves the assembly efficiency of the vibrating screen body and effectively solves the problems of complex and cumbersome installation of traditional support structures.

[0048] like Figure 5 As shown, the support plate 22 includes a frame 221, and a number of struts 222 arranged in a front-to-back pattern are fixed on the inner side of the frame 221. The front and rear sides of the frame 221 are both fixed with protruding brackets 225.

[0049] Existing screen plate support structures are prone to deformation during long-term screening, causing changes in the screen plate aperture and affecting screening accuracy. The frame 221 provides overall rigidity, the support rod 222 enhances the load-bearing capacity, and the clamping platform 225 provides a positioning reference for the perforated plate 21, enabling the perforated plate 21 to be stably laid on the support plate 22 and preventing the perforated plate 21 from shifting due to vibration during screening. This structure solves the problem of insufficient strength in traditional screen plate structures and improves screening accuracy and service life.

[0050] like Figure 5 As shown, several positioning posts 223 arranged in a left-right pattern are fixed on the upper surface of the frame 221 near the front and rear sides, and several card plates 224 are also fixed on the upper surface of the frame 221 near the front and rear sides.

[0051] During screening, the orifice plate 21 is prone to moving to the left or right due to vibration, which can lead to a decrease in screening accuracy. The positioning column 223 is inserted into the positioning hole 211 on the orifice plate 21 to keep the orifice plate 21 accurately positioned in the front and back directions. The clamping plate 224 clamps the edge of the orifice plate 21 and cooperates with the fastening groove 212 to achieve a firm clamping structure, thereby effectively preventing the orifice plate 21 from shifting under vibration and improving screening stability.

[0052] like Figure 6 As shown, the upper surface of the perforated plate 21 has several positioning holes 211 near the front and rear sides, and the front and rear edges of the perforated plate 21 have fastening grooves 212.

[0053] Existing perforated sieve plates are prone to loosening when the fixing method is insufficient, which leads to a decrease in screening efficiency. The positioning hole 211 and the positioning column 223 work together to achieve precise positioning of the perforated plate. The locking groove 212 and the clamping plate 224 interlock to form a stable locking structure, which keeps the perforated plate 21 stable and does not shift during the vibrating screening process, effectively solving the problem of the perforated plate structure not being firmly fixed.

[0054] like Figure 7 As shown, the locking mechanism 4 includes a locking block 42 sleeved on the adjusting shaft 61. Locking screws 41 are threadedly installed on both ends of the locking block 42. The adjusting shaft 61 is hung on the locking block 42 by a mounting plate.

[0055] Existing screen plate tilt locking structures generally suffer from the risk of loosening or complex adjustment issues. The locking block 42 is connected to the adjusting shaft 61 through the hanging platform structure, so that the adjusting shaft 61 forms a stable support within the locking block 42. When the locking screw 41 is tightened, it presses firmly against the adjusting shaft 61, so that the support frame 6 can quickly lock after the angle is adjusted. This structure improves the stability of angle adjustment, avoids the angle deviation of the screen plate during vibration, and solves the technical problems of unreliable angle locking and inconvenient adjustment in existing equipment.

[0056] The working principle of this utility model is as follows: When sorting ore by size, the ore is fed into the vibrating screen body by a belt conveyor. At this time, the vibrating screen body vibrates and screens the ore. Under the vibration of the vibrating screen body, the ore rolls to the right along the inclined direction of the upper screen plate 2 and is screened by the screen plate 2. The large ore remains on the upper screen plate 2 and is discharged through the upper guide chute 5. The ore that falls off the screen is screened again by the lower screen plate 2. At this time, the medium-sized ore rolls to the right along the inclined direction of the lower screen plate 2 and is screened by the lower screen plate 2. The medium-sized ore remains on the lower screen plate 2 and is discharged through the lower guide chute 5. The smallest ore falls to the bottom of the inner side of the shell 1 and is discharged through the discharge pipe 12, thereby completing the sorting of the ore by size.

[0057] When the types and fineness of the ore being sorted are different, the baffle 3 can be removed. At this time, the screen plate 2 can be directly removed from the support frame 6, and the perforated plate 21 can be disassembled and replaced with a perforated plate 21 of other aperture. Finally, the screen plates 2 are inserted and snapped into the support frame 6 to complete the replacement of the screen plate 2, making the replacement operation of the screen plate 2 more convenient.

[0058] The sieve plate 2 lays multiple perforated plates 21 on the support plate 22, which makes it easy to replace a single perforated plate 21 when it is damaged, without having to replace the entire sieve plate 2, thus greatly reducing maintenance costs.

[0059] When the sorting speed needs to be adjusted due to different types and fineness of the ore being sorted, loosen the locking screw 41 on the locking block 42, and then adjust the tilt angle of the support frame 6 and the screen plate 2. After the adjustment is completed, tighten the locking screw 41 again to fix the support frame 6, thereby completing the adjustment of the ore screening and sorting speed. The adjustment structure is simpler and the operation is more convenient and faster.

[0060] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
