Description
Technical Field
[0001] This utility model relates to the field of mining equipment technology, specifically to an adjustable mining hopper based on mining operations. Background Technology
[0002] In the current mining industry, ore extraction and processing is a complex and technically demanding process. In particular, during the ore extraction stage, ore is typically extracted through blasting operations. The blasted rock is then temporarily stored in large silos by transport trucks. Subsequently, this rock needs to be crushed by a crusher to meet the requirements for further processing or transportation.
[0003] Most existing crushers are equipped with fixed feed hoppers, where the height distance between the feed pipe of the hopper and the crusher's rotor is fixed. This design directly affects the crushing effect and throughput of the crusher. Specifically, the lower the feed pipe position, the longer the trajectory of the stone within the crushing chamber, and the better the crushing effect; conversely, the higher the feed pipe position, the greater the impact velocity of the falling stone, thus increasing the throughput. However, this fixed feed hopper design has significant limitations.
[0004] Because fixed feed hoppers cannot be adjusted according to actual production needs, in practical applications, it is often necessary to adapt various hopper specifications or replace the entire crushing equipment to different production environments and requirements. This not only leads to high initial investment costs but may also result in low production efficiency and resource waste due to mismatch between the hopper and production needs. Furthermore, fixed hoppers have poor adaptability and flexibility when handling stones of different hardness or volume, failing to fully utilize the crusher's performance. Therefore, the mining industry urgently needs a mining hopper that can be adjusted according to actual production needs to improve crushing efficiency and reduce costs. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable mining hopper based on mining operations, which solves the problem that existing fixed hoppers cannot be adjusted.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable mining hopper based on mining operations, comprising a crusher, wherein the top of the crusher is provided with a feed inlet, and an adjustable hopper is provided at the feed inlet. The adjustable hopper includes an assembly hopper, a fixed inner hopper, and a bottom hopper. The fixed inner hopper is fixed at the feed inlet. The assembly hopper is detachably connected to the outside or top of the fixed inner hopper, and the bottom hopper is located inside the fixed inner hopper and inside the crusher.
[0007] Preferably, the assembly hopper includes a first assembly hopper half-ring and a second assembly hopper half-ring assembled together. When the first assembly hopper half-ring and the second assembly hopper half-ring are assembled together, they can be sleeved on the outside of the fixed inner hopper or fixed to the top of the fixed inner hopper.
[0008] Preferably, the inlet is provided with an inner positioning ring connecting the fixed inner hopper and the bottom hopper.
[0009] Preferably, the inner positioning ring extends upward to form an upper extension that fits against the inner wall of the fixed inner hopper, and the inner wall surface of the upper extension is an inclined surface.
[0010] Preferably, the two sides of the inner positioning ring extend outward to form side extensions fixed to the inner wall of the crusher, and the bottom hopper is disposed on the side extensions.
[0011] Preferably, a side positioning platform is fixed to the tail end of the side extension, and guide rails are fixed to the two side extensions.
[0012] The bottom hopper includes a first bottom hopper half ring and a second bottom hopper half ring that are interlocked with each other. The top of the first bottom hopper half ring and the second bottom hopper half ring are provided with sliders that are slidably connected to the guide rail. The top side of the first bottom hopper half ring and the second bottom hopper half ring is connected to the side positioning platform by an elastic element.
[0013] Preferably, insert plates are provided on the opposite side walls of the first bottom hopper half-ring and the second bottom hopper half-ring, and insertion cavities are opened on the opposite side walls of the second bottom hopper half-ring and the first bottom hopper half-ring, and the insert plates are inserted into the insertion cavities.
[0014] Preferably, the elastic element includes:
[0015] The first cylinder is fixed on the first bottom hopper half ring or the second bottom hopper half ring;
[0016] The second cylinder is fixed on the side positioning platform and is sleeved on the first cylinder to form a cavity;
[0017] The spring is located inside the cavity, and its two ends are fixed to the first cylinder and the second cylinder, respectively.
[0018] The beneficial effects of this utility model are as follows: By using the adjustable mining hopper provided by this utility model, compared with the prior art, this hopper is composed of an assembly hopper, a fixed inner hopper, and a bottom hopper, realizing the modularization of the hopper's function. The first and second assembly hopper half-rings of the assembly hopper are assembled together as a whole, and can be sleeved on the outside of the fixed inner hopper or fixed on the top of the fixed inner hopper as needed, greatly improving the adaptability and versatility of the hopper. When the assembly hopper is sleeved on the outside of the fixed inner hopper, it can reinforce and protect the fixed inner hopper, effectively preventing deformation caused by impact during long-term use and extending the service life of the hopper. When the assembly hopper is fixed on the top of the fixed inner hopper, it is equivalent to lengthening the height of the hopper, which increases the material drop distance and improves the crushing effect, especially when processing materials that require a long crushing trajectory, it can significantly improve the crushing quality. The bottom hopper consists of a first bottom hopper half-ring and a second bottom hopper half-ring. When processing large pieces of ore, if the ore gets stuck in the bottom hopper, the two half-rings of the bottom hopper can open and close outward along the guide rail and automatically reset with the help of elastic elements. This effectively avoids equipment downtime caused by blockage by large pieces of ore and improves production efficiency. Attached Figure Description

[0029] The technical solutions of the present invention 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 invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.
[0030] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0031] Reference Figure 1-8 This implementation plan describes an adjustable mining hopper based on mining operations.
[0032] like Figure 1 and Figure 2 As shown, the system includes a crusher 1, with a feed inlet 2 at the top. An adjustable hopper is located at the feed inlet 2, comprising an assembly hopper 3, a fixed inner hopper 4, and a bottom hopper 5. The fixed inner hopper 4 is fixed to the feed inlet 2. The assembly hopper 3 is detachably connected to the outside or top of the fixed inner hopper 4. The bottom hopper 5 is located inside the fixed inner hopper 4, at the feed inlet 2, and extends into the crusher 1, forming an inner hopper hidden inside the crusher 1. This extends the material drop distance and shortens the distance the material travels from the feed inlet 2 to the impact plate inside the crusher 1, allowing the material to fall directly onto the impact plate and preventing material deviation. It should be noted that the bottom of the bottom hopper 5 is suspended above the impact plate inside the crusher 1, with a certain gap maintained between them.
[0033] like Figure 6 As shown, the assembly hopper 3 includes a first assembly hopper half-ring 31 and a second assembly hopper half-ring 32 assembled together. In specific implementations, such as... Figures 1 to 4 As shown, when the first assembly hopper half-ring 31 and the second assembly hopper half-ring 32 are assembled together, they can be sleeved on the outside of the fixed inner hopper 4 or fixed to the top of the fixed inner hopper 4.
[0034] In one embodiment, when the first assembly hopper half-ring 31 and the second assembly hopper half-ring 32 constituting the assembly hopper 3 are assembled together and sleeved on the outside of the fixed inner hopper 4, the outside of the fixed inner hopper 4 is reinforced and protected, preventing the fixed inner hopper 4 from being deformed by impact during long-term use.
[0035] In another embodiment, when the first assembly hopper half-ring 31 and the second assembly hopper half-ring 32 constituting the assembly hopper 3 are assembled together and fixed to the top of the fixed inner hopper 4, an extended hopper is formed at the top of the fixed inner hopper 4, which increases the height of the hopper and lengthens the material drop distance, thereby improving the crushing effect.
[0036] like Figure 5 As shown, an inner positioning ring 6 is provided at the inlet 2, connecting the fixed inner hopper 4 and the bottom hopper 5, forming a transition between the fixed inner hopper 4 and the bottom hopper 5, so that the ore can fall smoothly from the fixed inner hopper 4 into the bottom hopper 5.
[0037] In a preferred embodiment, the inner positioning ring 6 extends upward to form an upper extension 62 that fits against the inner wall of the fixed inner hopper 4. The inner wall of the upper extension 62 is a slope 7. Since the upper extension 62 fits against the inner wall of the inner hopper 4, it seals the gap between the fixed inner hopper 4 and the bottom hopper 5. The design of the slope 7 can prevent the formation of steps and ensure that the ore falls smoothly.
[0038] In another preferred embodiment, the inner positioning ring 6 extends outward on both sides to form side extensions 61 fixed to the inner wall of the crusher 1, and the bottom hopper 5 is disposed on the side extensions 61.
[0039] Furthermore, a side positioning platform 8 is fixed to the tail end of the side extension 61, and guide rails 10 are fixed to the two side extensions 61; such as Figure 7 As shown, the bottom hopper 5 includes a first bottom hopper half ring 51 and a second bottom hopper half ring 52 that are interlocked with each other. The top of the first bottom hopper half ring 51 and the second bottom hopper half ring 52 are both provided with sliders 11 that are slidably connected to the guide rail 10. The top side of the first bottom hopper half ring 51 and the second bottom hopper half ring 52 is connected to the side positioning platform 8 by an elastic member 9.
[0040] Insert plates 54 are provided on the opposite side walls of the first bottom hopper semi-ring 51 and the second bottom hopper semi-ring 52. Insert cavities 53 are opened on the opposite side walls of the second bottom hopper semi-ring 52 and the first bottom hopper semi-ring 51. Insert plates 54 are inserted into the insert cavities 53.
[0041] In practical implementation, since the inner diameters of the assembly hopper 3, the fixed inner hopper 4, and the bottom hopper 5 decrease sequentially, the bottom hopper 5, which is located at the bottom, has the smallest inner diameter. Therefore, it is formed by connecting two first bottom hopper half-rings 51 and second bottom hopper half-rings 52. When a large amount of ore falls in and is stuck in the bottom hopper 5, the first bottom hopper half-rings 51 and second bottom hopper half-rings 52 can open and close to both sides. At this time, the first bottom hopper half-rings 51 and second bottom hopper half-rings 52 are slidably connected to the guide rail 10 through the slider 11. After the ore falls, the first bottom hopper half-rings 51 and second bottom hopper half-rings 52 are closed by the push of the elastic element 9.
[0042] like Figure 8 As shown, the elastic element 9 includes a first cylinder 91, a spring 92, and a second cylinder 93. The first cylinder 91 is fixed to either the first bottom hopper half-ring 51 or the second bottom hopper half-ring 52; the second cylinder 93 is fixed to the side positioning platform 8 and is sleeved on the first cylinder 91 to form a cavity; the spring 92 is located in the cavity and its two ends are fixed to the first cylinder 91 and the second cylinder 93, respectively.
[0043] In practice, when a large amount of ore falls into the hopper and gets stuck in the bottom hopper 5, the first bottom hopper semi-ring 51 and the second bottom hopper semi-ring 52 open to the sides and move the first cylinder 91 outwards and retract into the second cylinder 93, at which point the spring 92 is compressed. After the ore falls, the elastic force of the spring 92 pushes the first bottom hopper semi-ring 51 and the second bottom hopper semi-ring 52 back to their original positions, causing them to close.
[0044] During this process, the insert plate 54 moves within the insert cavity 53 to seal the gap between the first bottom hopper half ring 51 and the second bottom hopper half ring 52 when they open and close.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
