Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary crushing device for large pieces of ore. Background Art
[0002] In the mining or gravel industry, it is often necessary to crush ore or other materials. Generally, the equipment for crushing and processing includes: cone crusher, jaw crusher, impact crusher, hammer crusher, roll crusher, impact crusher, compound crusher, etc.
[0003] Generally, crushers process larger pieces of materials, and the product particle size is relatively coarse, usually greater than 8 mm. Its structural feature is that there is a certain gap between the crushing parts and they do not contact each other. Crushers can be further divided into primary crushers, secondary crushers and fine crushers.
[0004] For primary crushing operations, a jaw crusher is generally used to process larger pieces of materials or ore; a jaw crusher consists of a machine shell, a rotor, a striking plate, a hammer head, a bracket, a lining plate, etc.
[0005] A jaw crusher is a crushing machine that uses the extrusion and bending action of two jaw plates to crush various hardness materials in primary or secondary crushing. Its crushing mechanism consists of a fixed jaw plate and a movable jaw plate. When the two jaw plates approach, the material is crushed, and when the two jaw plates separate, the material blocks smaller than the discharge opening are discharged from the bottom.
[0006] Under some non-industrial test conditions, there are cases where some large pieces of ore materials are too large to be fed into the jaw crusher. In practice, these large pieces of materials are generally broken by manual hammering or renting other large hydraulic equipment for stamping, which causes some difficulties to the entire crushing operation. Content of the Utility Model

[0022] Such as Figure 1As shown in Fig. 4, an auxiliary crushing device for large pieces of ore includes a support frame 1. A bottom cylinder 4 is provided at the bottom of the support frame 1, and large pieces of ore are placed inside the bottom cylinder 4. A pulley block 2 is provided at the top of the support frame 1, and a solid steel column 3 is suspended below the pulley block 2. The solid steel column 3 is located above the bottom cylinder 4.
[0023] As Figure 1 shown, the support frame 1 includes a support frame main body 11. The support frame main body 11 is a frame structure. A central cylinder 12 is provided at the center inside the support frame main body 11. The central cylinder 12 is fixed to the support frame main body 11 through a support rod 13. A pulley support 14 is provided at the top of the support frame main body 11, and a pulley fixing ring 15 is provided at the top of the pulley support 14. The pulley block 2 is fixed on the pulley fixing ring 15.
[0024] It should be noted that the axes of the pulley block 2, the solid steel column 3, the central cylinder 12, and the bottom cylinder 4 are concentric.
[0025] As Figure 2 shown, the pulley block 2 includes a fixed pulley 21 fixed on the pulley fixing ring 15. The fixed pulley 21 is in transmission connection with a movable pulley 22, and a hook 23 is connected below the movable pulley 22. To ensure normal operation, steel wire ropes are wound around the fixed pulley 21 and the movable pulley 22, and the steel wire ropes are connected to a drum mechanism, which is a well-known technology to those skilled in the art.
[0026] As Figure 3 shown, the solid steel column 3 includes a column body 31, and a lifting lug 32 is provided above the column body 31. Among them, the outer diameter of the column body 31 is slightly smaller than the inner diameter of the central cylinder 12 of the support frame 1, so that the solid steel column 3 can smoothly pass through the central cylinder 12 in the up and down directions. At this time, the function of the central cylinder 12 of the support frame is to ensure that the solid steel column 3 can move freely up and down and prevent it from tipping over.
[0027] As Figure 4 shown, the bottom cylinder 4 includes a lower cylinder 41, and an upper cylinder 42 is provided above the lower cylinder 41. An upper cylinder cover 43 is covered on the upper cylinder 42. Among them, the upper cylinder cover 43 is composed of two semi-circular plates. A circular hole 44 is dug out in the center of the upper cylinder cover 43, and the diameter of the circular hole 44 is larger than that of the solid steel column 3 to ensure that the solid steel column 3 can fall into the circular hole 44.
[0028] Furthermore, the upper cylinder cover 43 is movably connected to the upper cylinder 42, and the two can be movably separated from each other.
[0029] Furthermore, the upper cylinder 42 has no bottom and its diameter is slightly smaller than that of the lower cylinder 41. The height of the lower cylinder 41 is about one-fifth of the height of the upper cylinder 42. The upper cylinder 42 is placed on the lower cylinder 41. This structure can realize the free disassembly and combination of the cylinders, and at the same time, the structure of the bottom cylinder 4 can prevent the ore from splashing when it is crushed.
[0030] The working principle of the present utility model is as follows:
[0031] The support frame 1 is fixed by the bottom anchor bolts. The pulley block 2 is pre-assembled onto the pulley bracket 14. The bottom cylinder 4 is placed below the support frame 1. During operation, the pulley block 2 passes through the center cylinder 12 via the lifting lug 32 to lift the solid steel column 3. Large pieces of ore are placed inside the bottom cylinder 4. By instantaneously releasing the tension of the pulley block 2, the solid steel column 3 falls freely and smashes the ore inside the bottom cylinder. Through cyclic operation, the preliminary crushing of large pieces of minerals is achieved until they can be smoothly fed into the subsequent crushing operation equipment.
[0032] During operation, multiple pulley blocks 2 can be adopted to reduce the manual load.
[0033] This device has a simple structure and is convenient to operate. It does not require other mechanical power and electricity, and can be used as an auxiliary operation for material crushing.
[0034] The above are only the preferred embodiments of the present utility model. It should be noted that for those skilled in the art, without departing from the overall concept of the present utility model, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present utility model.
