Description

Technical Field

[0001] This utility model relates to the field of mining crushing devices, and in particular to a mining crushing device. Background Technology

[0002] Crushing equipment in mining operations is a key piece of equipment used to crush large pieces of ore into smaller pieces. Cone crushers utilize the eccentric rotation of the moving cone within the fixed cone to continuously subject the ore to compression, bending, and shearing within the crushing chamber, resulting in a large crushing ratio, high efficiency, low energy consumption, and more uniform product particle size.

[0003] However, in existing mining crushing devices, all the mined ores of various sizes are poured into the inside of the crushing device, which not only occupies the internal space of the crushing device, but also makes it difficult to directly and quickly crush large pieces of ores. Therefore, we propose a mining crushing device to solve the problems mentioned above. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a mining crushing device that can solve the technical problem that in existing mining crushing devices, all the mined ores of various volumes are poured into the inside of the crushing device, which occupies the internal space of the crushing device and is not conducive to the direct and rapid crushing of large pieces of ores.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a cone crusher body, a screen box fixedly installed at the outer end of the cone crusher body, an installation frame fixedly installed on the inner wall of the screen box, a vibrating support leg fixedly installed at the upper end of the installation frame, an alloy spring provided on the outer side of the vibrating support leg, a metal mesh plate fixedly installed at the upper end of the vibrating support leg, a vibrating motor fixedly installed at the outer end of the metal mesh plate, a guide slope fixedly installed at the inner end of the screen box, a discharge port opened at the inner end of the screen box, and a discharge frame fixedly installed at the lower end of the screen box.

[0006] As a preferred embodiment of this utility model, a mounting platform is fixedly installed at the lower end of the cone crusher body, and a power motor is fixedly installed at the outer end of the mounting platform.

[0007] As a preferred embodiment of this utility model, a conveyor belt is provided on the lower side of the mounting platform, and the conveyor belt is located on the lower side of the discharge rack.

[0008] As a preferred embodiment of this utility model, a moving cone is rotatably installed inside the cone crusher body, and a crossbeam is rotatably installed at the upper end of the moving cone, with the crossbeam fixedly installed at the top of the cone crusher body.

[0009] As a preferred embodiment of this utility model, an elastic dust cover is fixedly connected to the outer end of the metal mesh plate, and the end of the elastic dust cover away from the metal mesh plate is fixedly connected to the mounting frame.

[0010] As a preferred embodiment of this utility model, the guide slope is fixedly connected to the outer wall of the cone crusher body, and the cone crusher body is located on the lower side of the metal mesh plate.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. Equipped with a screen box, metal mesh plate and vibrating motor, the ore to be crushed falls onto the upper side of the metal mesh plate. The vibrating motor drives the metal mesh plate to vibrate. Smaller stones fall directly into the inside of the screen box, while larger ones enter the inside of the cone crusher for crushing. This screens out the smaller stones, allowing the larger pieces of ore to enter the crushing chamber and preventing them from entering together and affecting the crushing efficiency.

[0013] 2. Equipped with a guide slope, a feeding port, and a discharge rack, the screened small ore falls from the feeding port to the discharge rack along the inclined direction of the guide slope, and then falls onto the conveyor belt for transportation together with the crushed ore. The structure is coherent and highly practical. Attached Figure Description

[0020] Example

[0021] Please refer to Figure 1-4 As shown, this utility model provides a crushing device for mining operations.

[0022] A screen box 2 is fixedly installed at the outer end of the cone crusher body 1. A mounting frame 3 is fixedly installed on the inner wall of the screen box 2. A vibrating support leg 4 is fixedly installed at the upper end of the mounting frame 3. An alloy spring 5 is installed on the outer side of the vibrating support leg 4. A metal mesh plate 7 is fixedly installed at the upper end of the vibrating support leg 4. A vibrating motor 8 is fixedly installed at the outer end of the metal mesh plate 7. A moving cone 12 is rotatably installed inside the cone crusher body 1. A crossbeam 13 is rotatably installed at the upper end of the moving cone 12 and is fixedly installed at the top of the cone crusher body 1. An elastic dust cover 6 is fixedly connected to the outer end of the metal mesh plate 7. The end of the elastic dust cover 6 away from the metal mesh plate 7 is fixedly connected to the mounting frame 3. This allows smaller stones to be screened out, allowing larger pieces of ore to enter the crushing chamber, preventing them from entering together and affecting crushing efficiency.

[0023] A guide slope 9 is fixedly installed at the inner end of the screening box 2, and a discharge port 10 is opened at the inner end of the screening box 2. A discharge rack 11 is fixedly installed at the lower end of the screening box 2. A mounting platform 14 is fixedly installed at the lower end of the cone crusher body 1, and a power motor 15 is fixedly installed at the outer end of the mounting platform 14. A conveyor belt 16 is provided on the lower side of the mounting platform 14, and the conveyor belt 16 is located on the lower side of the discharge rack 11. The guide slope 9 is fixedly connected to the outer wall of the cone crusher body 1, and the cone crusher body 1 is located on the lower side of the metal mesh plate 7, with a continuous structure and strong practicality.

[0024] Specific working principle:

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when using this mining crushing device, the ore to be crushed is poured from the top of the screen box 2 into the interior of the cone crusher body 1. The ore falls onto the top of the metal mesh plate 7. The vibrating motor 8 drives the metal mesh plate 7 to vibrate, the alloy spring 5 vibrates up and down, and the vibrating support leg 4 vibrates regularly. This allows the smaller pieces of ore to pass directly through the metal mesh plate 7 and fall into the interior of the screen box 2, no longer entering the interior of the cone crusher body 1 for further crushing. Larger pieces of ore slide into the interior of the cone crusher body 1, and the power motor 15 drives... The moving cone 12 rotates, crushing the ore during the rotation. The crushed ore falls from the lower part of the mounting platform 14 to the upper part of the conveyor belt 16 for conveying and leaving. The smaller pieces of ore that enter the screen box 2 slide down the inclined angle of the guide slope 9 to the feed port 10, and then slide down from the discharge rack 11 to the upper part of the conveyor belt 16 for conveying and leaving together. The above completes a series of operations of the mining crushing device. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
