Description

Technical Field

[0001] This utility model relates to the field of screen technology, and more specifically, to a mining screen that is easy to store. 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, with metallic ores being the main raw materials for the smelting industry and non-metallic ores being important chemical raw materials and building materials.

[0003] For example, the Chinese utility model patent (publication number: CN208853248U) discloses a "mining screen". The specification of the mining screen states that: the mining screen is provided with a hinge connecting the first screen and the second screen, so that both the first screen and the second screen can rotate around the hinge. When the first screen and the second screen are rotated to overlap, the size of the whole device is changed, making it easy to carry. The guide rail and the slider can slide against each other, thereby driving the connecting parts to slide relative to the fixed seat. The position of the first screen and the second screen relative to the fixed seat can be adjusted to meet the needs of miners to change the distance between the first screen and the second screen and themselves as needed, so as to facilitate the screening operation.

[0004] Regarding the aforementioned technologies, this device has some shortcomings. In actual use, the screening angle is relatively simple, and it can only operate in the vertical direction. This fixed structural design results in a short contact path between the material and the screen surface and insufficient contact time, which limits the material from fully tumbling and passing through the screen, making it difficult to achieve a more thorough screening effect and affecting the overall screening efficiency and quality.

[0005] Therefore, we have made improvements to this by proposing a mining screen that is easy to store. Utility Model Content

[0032] Example 1

[0033] Please refer to Figures 1-5 A mining screen that is easy to store includes a first screen frame 1 and a second screen frame 2. A hinge 10 is provided on the front of the connection between the first screen frame 1 and the second screen frame 2. A fixing box 3 is hinged to the lower outer side of the first screen frame 1 and the second screen frame 2. Several fixing bolts 6 are provided at the bottom of the fixing box 3.

[0034] The upper part of the inner side of the outer surface of the two fixed boxes 3 is hinged with a first connecting rod 7, and the upper part of the outer side of the first screen frame 1 and the second screen frame 2 is hinged with a second connecting rod 8. One end of the second connecting rod 8 is hinged to one end of the first connecting rod 7 at the corresponding position. The screen 9 is fixedly installed inside the first screen frame 1 and the second screen frame 2. A locking component is provided on the inner surface of the fixed box 3.

[0035] Furthermore, the bottom of the fixing box 3 is provided with threaded holes corresponding to the position and number of fixing bolts 6. The fixing box 3 is threadedly connected to the fixing bolts 6 through the threaded holes on the bottom. This achieves precise alignment and reliable locking of the fixing bolts 6 and the fixing box 3.

[0036] Furthermore, a sealing plate 4 is hinged to the opening on the front of the fixed box 3, and a latch is provided at the connection between the sealing plate 4 and the side of the front of the fixed box 3. This effectively seals the internal structure of the fixed box 3, preventing impurities from entering and affecting the operation of the transmission components, while also allowing staff to easily open it for internal inspection and maintenance, thus balancing protection and operability.

[0037] Furthermore, a handle 11 is fixedly installed on the outer surface of the fixed box 3. This provides a direct gripping point for the handling, relocation, and folding of the device, making operation more effortless and convenient.

[0038] Furthermore, the first screen frame 1, the second screen frame 2, and the screen mesh 9 are all made of stainless steel. They possess excellent corrosion resistance and structural strength, effectively resisting material erosion and moisture attack, significantly extending the service life of the device and reducing maintenance costs.

[0039] Example 2

[0040] The mining screen provided in Embodiment 1 is further optimized. Specifically, the locking assembly includes a positioning post 5 that is movably inserted into the inner surface of the fixed box 3. A baffle 13 is fixedly installed on one end of the positioning post 5 inside the fixed box 3. A symmetrically distributed spring 12 is fixedly installed between the inner surface of the baffle 13 and the inner surface of the fixed box 3. Limiting grooves 15 are opened on the outer sides of the first screen frame 1 and the second screen frame 2. The limiting grooves 15 are engaged with the positioning post 5.

[0041] Furthermore, an operating block 14 is fixedly installed at the front end of the baffle 13. This provides the operator with a clear force point, facilitating the application of force and effectively improving the convenience and control of the adjustment process.

[0042] Furthermore, the fixing box 3 is provided with sliding holes that are compatible with the positioning post 5. The fixing box 3 is slidably connected to the positioning post 5 through the sliding holes. The sliding holes provide precise guidance and stable support for the positioning post 5, ensuring smooth movement and preventing deviation during extension and retraction, thereby improving the accuracy and reliability of the positioning operation.

[0043] The following is the usage process of the mining sieve that is easy to store, provided by this utility model:

[0044] In use, firstly, drill threaded holes corresponding to the positions and number of fixing bolts 6 on a hard surface using a drilling tool. Keep the first screen frame 1 and the second screen frame 2 in their unfolded state, aligning the bottoms of the two fixing boxes 3 with the corresponding drilled holes. Then, insert the fixing bolts 6 through the bottom of the fixing box 3 from the inside and screw them into the pre-drilled holes in the ground, thus firmly fixing the fixing box 3 to the ground and completing the base installation. Next, tilt the top of the first screen frame 1 and the second screen frame 2 backwards. Utilizing the hinge relationship between the first connecting rod 7 and the second connecting rod 8 and the fixing box 3, tilt the first screen frame 1 and the second screen frame 2 backwards to a preset angle. Under the limiting action of the fixing box 3, maintain this tilted posture and stably install them on the ground. At this point, the worker can then place the material... The material is thrown onto the screen 9 on the first screen frame 1 and the second screen frame 2. Since the screen 9 is tilted with the screen frame, the material rolls down the surface of the screen 9 under the action of gravity. During this process, the screen 9 fully screens the material, which significantly improves the screening efficiency and quality. After use, the first screen frame 1 and the second screen frame 2 are first reset to the vertical position, so that the first connecting rod 7 and the second connecting rod 8 are folded, so that the first screen frame 1 and the second screen frame 2 are stored vertically between the two fixed boxes 3. Then, the fixing bolts 6 between the fixed boxes 3 and the ground are removed, so that the fixed boxes 3 are released from the fixed connection with the ground. Then, the two fixed boxes 3 are folded backward, which drives the first screen frame 1 and the second screen frame 2 to move synchronously. Finally, the whole device is folded and stored, which greatly reduces the volume and makes it easy to carry and store. It has high practicality and ease of operation.

[0045] When the first sieve frame 1 and the second sieve frame 2 are vertically reset between the two fixed boxes 3, the operating block 14 is first moved from inside the fixed box 3. The operating block 14 drives the baffle 13 connected to it to move. The movement of the baffle 13 causes the positioning post 5 to retract into the fixed box 3. At the same time, the movement of the baffle 13 stretches the spring 12, causing it to undergo elastic deformation. After the positioning post 5 is fully retracted to a suitable position that does not affect the reset of the first sieve frame 1 and the second sieve frame 2, the first sieve frame 1 and the second sieve frame 2 are vertically reset between the two fixed boxes 3. Then the limiting position of the operating block 14 is released. At this time, under the action of the elastic restoring force of the spring 12, the spring 12 drives the positioning post 5 to move in the opposite direction through the baffle 13 and accurately lock into the preset limiting groove 15 on the side of the first sieve frame 1 and the second sieve frame 2. This ensures the stability of the first sieve frame 1 and the second sieve frame 2 in a vertical state between the two fixed boxes 3, so as to facilitate the subsequent stable folding and storage operation of the first sieve frame 1 and the second sieve frame 2.
