Description

Technical Field

[0001] This utility model relates to the field of ore screening technology, specifically an ore screening device. Background Technology

[0002] Mining is the technology and science of extracting mineral resources from within the Earth's crust and on its surface. In a broader sense, mining also includes the extraction of coal and oil. The mining industry is an important raw material industry. Metallic ores are the main raw materials for the smelting industry, while non-metallic ores are important chemical raw materials and building materials. After the ores are extracted, they need to be screened and processed. Different ores undergo different deep processing.

[0003] Chinese utility model patent CN221581058U discloses a ore screening device, including a screening component. The screening component includes a screen plate with multiple sets of small holes and multiple sets of large holes. The screen plate is mounted on a support frame, and a blockage removal component is mounted on the support frame. The blockage removal component includes a movable plate slidably mounted on the support frame. The movable plate has multiple sets of top columns (first type) adapted to the small holes and multiple sets of top columns (second type) adapted to the large holes. This device removes soil and stuck ore from small holes using a top column one, and removes soil and ore from large holes using a top column two. It also allows the movable plate to be placed on one side of the support frame, preventing it from blocking the screen plate and causing the ore to fall after screening. It eliminates the need for water flushing to remove soil and ore from small and large holes, saving costs. However, this existing ore screening device requires manual lifting of the top columns to clean the soil and ore from the screen holes. This cleaning method increases the labor intensity for workers, and the top columns push up ore of varying sizes from both holes, causing them to mix together and flow into the storage tank, inconveniencing the ore screening process.

[0004] Therefore, this utility model provides an ore screening device to solve the above problems. Utility Model Content

[0005] This utility model provides an ore screening device, which aims to solve the problems mentioned in the background art, such as the existing ore screening devices cleaning the mud and ore in the screen holes by manually lifting the top column, which increases the labor intensity of workers, and the top column pushes the ore of different sizes in the holes upward, causing the ore of different sizes to mix together and flow into the storage box, which brings inconvenience to the ore screening work.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ore screening device, comprising a base, wherein a first support plate and two sets of second support plates symmetrically arranged on the rear side of the end face of the base are symmetrically installed on the front side of the end face of the base, and a fixing shell is installed on the upper side wall of the first support plate and the second support plate, wherein a screen plate and a cleaning structure arranged on the mounting groove are installed on the fixing shell through a mounting groove. The cleaning structure includes four sets of vertical plates installed on the upper part of the fixed shell. The upper ends of the four sets of vertical plates are connected by a top plate. Hydraulic cylinders are installed on the front and rear sides of the top plate through through holes. A connecting block is provided at the driving end of the hydraulic cylinder. The lower sides of the two sets of connecting blocks are connected by a moving plate. A first push rod is installed on the rear bottom side of the moving plate, and a second push rod is installed on the front bottom side of the moving plate. By setting up a cleaning structure, the hydraulic cylinder drives multiple sets of first and second push rods to move downwards, pushing out the mud and stuck ore in the large and small screen holes. This replaces manual operation, reducing the labor intensity of workers. At the same time, after the large and small ore in the large and small screen holes are pushed downwards, they fall into the corresponding collection chambers on the collection box, avoiding the mixing of large and small ore. This solves the problem that existing ore screening devices rely on manually lifting the top column to clean the mud and ore in the screen holes. This cleaning method increases the labor intensity of workers, and the top column pushes the large and small ore in the large and small holes upwards, causing the large and small ore to mix together and flow into the storage box, which brings inconvenience to the ore screening work.

[0007] Preferably, two sets of limiting blocks are installed on the front and back of the sieve plate, threaded sleeves are symmetrically installed on the bottom of the sieve plate on the left and right sides, and a fixing ring is installed on the bottom of the fixing shell corresponding to the threaded sleeve, and bolts are installed on the inner wall of the fixing ring.

[0008] Preferably, the end face of the base is provided with a collection box, the inner cavity of the collection box is provided with two sets of partitions, the end face of the base is installed with a guide strip, and the bottom of the collection box is provided with a connecting groove corresponding to the guide strip.

[0009] Preferably, handles are installed on the front and rear side walls of the collection box, and a traveling wheel is installed at the bottom of the base and at the corner. The traveling wheel is a lockable universal wheel.

[0010] Preferably, the movable plate, the top plate, and the sieve plate are arranged in pairs parallel to each other, and multiple sets of the first and second top rods are provided, with spikes at the lower ends of the first and second top rods.

[0011] Preferably, the sieve plate has a large sieve hole corresponding to the second top rod, and the sieve plate has a small sieve hole corresponding to the first top rod.

[0012] Preferably, a slot is provided on the fixed shell corresponding to the limiting block, and the slot and the limiting block are adapted to each other.

[0013] Beneficial effects: By setting up a cleaning structure, the hydraulic cylinder drives multiple sets of first and second push rods to move downwards, pushing out the mud and stuck ore in the large and small screen holes, replacing manual operation and reducing the labor intensity of workers. At the same time, after the large and small ores in the large and small screen holes are pushed downwards, they fall into the corresponding collection chambers on the collection box, avoiding the mixing of large and small ores. This solves the problem that existing ore screening devices rely on manually lifting the top column to clean the mud and ore in the screen holes. This cleaning method increases the labor intensity of workers, and the top column pushes the large and small ores upwards, causing them to mix together and flow into the storage box, which brings inconvenience to the ore screening work. This makes the ore screening device more effective. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 This embodiment provides an ore screening device, such as... Figure 1-4As shown, the ore screening device includes a base 1, a first support plate 2 symmetrically installed on the front side of the end face of the base 1 and two sets of second support plates 3 symmetrically arranged on the rear side of the end face of the base 1, and a fixed shell 4 is installed on the upper side wall of the first support plate 2 and the second support plate 3. The fixed shell 4 is equipped with a screen plate 5 and a cleaning structure 6 arranged on the installation groove 41 through the installation groove 41. The cleaning structure 6 includes four sets of vertical plates 61 installed on the upper part of the fixed shell 4. The upper ends of the four sets of vertical plates 61 are connected by a top plate 62. Hydraulic cylinders 63 are installed on the front and rear sides of the top plate 62 through through holes 621. A connecting block 64 is provided at the driving end of the hydraulic cylinder 63. The lower sides of the two sets of connecting blocks 64 are connected by a moving plate 65. A first push rod 66 is installed on the rear bottom side of the moving plate 65, and a second push rod 67 is installed on the front bottom side of the moving plate 65.

[0018] In use, the two sets of hydraulic cylinders 63 are activated via the control panel. The two sets of hydraulic cylinders 63 extend downwards synchronously, causing the connecting blocks 64 to move downwards. The connecting blocks 64, in turn, move the moving plate 65 downwards. The moving plate 65, carrying multiple sets of first push rods 66 and second push rods 67, moves them into the corresponding small screen holes 52 and large screen holes 51. This pushes out the mud and stuck ore in the large screen holes 51 and small screen holes 52, replacing manual operation and reducing the labor intensity of workers. Simultaneously, the ore of different sizes pushed out of the large and small screen holes 51 and 52 falls downwards into the corresponding ore collection chambers on the collection box 11, preventing the mixing of large and small ores. This solves the problem of existing ore screening devices requiring manual lifting of the top column to clean the mud and ore from the screen holes, which increases the labor intensity of workers and causes the ore to mix together and flow into the storage box, making ore screening inconvenient. Therefore, this ore screening device performs better.

[0019] In this embodiment, a collection box 11 is provided on the end face of the base 1, and two sets of partitions 111 are provided in the inner cavity of the collection box 11. A guide strip 12 is installed on the end face of the base 1, and a connecting groove 112 is provided on the bottom of the collection box 11 corresponding to the guide strip 12. The partition 111 can be used to divide the collection box 11 into three collection chambers, which can be used to collect and store different sizes of ore separately after screening. In this embodiment, handles 13 are installed on the front and rear side walls of the collection box 11, and a walking wheel 14 is installed at the bottom of the base 1 and at the corner. The walking wheel 14 is a lockable universal wheel. The walking wheels 14 facilitate the movement of the ore screening device, improving the flexibility of the device. At the same time, the walking wheels 14 can be locked, which can lock the parked screening device in place. In this embodiment, the movable plate 65, the top plate 62, and the sieve plate 5 are arranged in pairs parallel to each other. Multiple sets of the first top rod 66 and the second top rod 67 are provided. The lower ends of the first top rod 66 and the second top rod 67 are provided with spikes. A large sieve hole 51 is opened on the sieve plate 5 corresponding to the second top rod 67, and a small sieve hole 52 is opened on the sieve plate 5 corresponding to the first top rod 66.

[0020] Example 2 Unlike Embodiment 1, the screen plate of the existing ore screening device is fixedly installed on the device. After long-term use, the screen plate will deform and wear, making it inconvenient to replace the screen plate. Therefore, two sets of limiting blocks 7 are installed on the front and back of the screen plate 5. Threaded sleeves 8 are symmetrically installed on the bottom of the screen plate 5 and on the left and right sides. A fixing ring 9 is installed on the bottom of the fixing shell 4 and corresponding to the threaded sleeve 8. Bolts 10 are installed on the inner wall of the fixing ring 9. In use, multiple sets of bolts 10 are disassembled one by one, and then the screen plate 5 is moved upward. The screen plate 5 is disassembled by using the mounting groove 41 and taking multiple sets of limiting blocks 7 away from the slot 42. Then, a new screen plate 5, limiting blocks 7 and threaded sleeve 8 are replaced. The screen plate 5 is moved downward to the mounting groove 41, so that the screen plate 5 and multiple sets of limiting blocks 7 enter the slot 42 and the threaded sleeve 8 is aligned with the fixing ring 9. The bolts 10 and threaded sleeve 8 are threaded together by using a wrench, so that the threaded sleeve 8 and the fixing ring 9 are fixed together, thus fixing the screen plate 5 and facilitating the replacement of the screen plate 5, thereby improving the use effect of the ore screening device. In this embodiment, a slot 42 is provided on the fixed shell 4 and corresponding to the limiting block 7. The slot 42 and the limiting block 7 are adapted to each other.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
