The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] This application provides a multi-stage splash-proof crushing device for limestone, as shown in the schematic diagram below. Figure 1-4 As shown. The limestone multi-stage anti-splash crushing device includes a crusher body 10, a feed box 20 connected to the top of the crusher body 10, and an anti-splash mechanism 30 connected inside the feed box 20;

[0026] The splash-proof mechanism 30 includes a first guide plate 31 connected to one end of the inside of the feed box 20, and a second guide plate 32 connected to the other end of the inside of the feed box 20. The second guide plate 32 is located at the bottom of the first guide plate 31, and an extension protection component 33 is connected to the end of the first guide plate 31 away from the inner wall of the feed box 20.

[0027] It should be noted that in this embodiment, the feed box 20 at the top of the crusher body 10 is used to receive limestone material, and the splash-proof mechanism 30 inside the feed box 20 plays a key role. The first guide plate 31 first receives the incoming material and provides initial guidance. Subsequently, the material slides down to the second guide plate 32 located at its bottom, and the second guide plate 32 further guides the material into the crusher body 10. The extended protective component 33 at the end of the first guide plate 31 can be adjusted in length as needed to enhance the blocking and guiding effect on the material.

[0028] Optionally, such as Figure 1 and Figure 3 As shown, both the first guide plate 31 and the second guide plate 32 are inclined, and the included angle between the first guide plate 31 and the second guide plate 32 is 30-45°.

[0029] In this embodiment, both the first guide plate 31 and the second guide plate 32 are inclined, and the two maintain an angle of 30-45°. This angle design allows the material to slide from the first guide plate 31 to the second guide plate 32, forming a buffer transition, and the impact force of the material is dispersed during the angle change.

[0030] Optionally, such as Figure 1 and Figure 2 As shown, both the first guide plate 31 and the second guide plate 32 are connected to the body of the feed box 20 via a rotating shaft 34.

[0031] In this embodiment, the first guide plate 31 and the second guide plate 32 are connected to the feed box 20 via a rotating shaft 34, allowing the first guide plate 31 and the second guide plate 32 to rotate around the rotating shaft 34 at a certain angle. When material impacts the first guide plate 31 and the second guide plate 32, they can automatically adjust their angle according to the magnitude of the impact force. The rotating shaft 34 provides the first guide plate 31 and the second guide plate 32 with a certain degree of flexibility, adapting to materials of different sizes and hardness, and avoiding feeding difficulties caused by differences in material characteristics; at the same time, the rotation process can buffer the impact of the material, reducing damage to the first guide plate 31, the second guide plate 32, and the feed box 20.

[0032] Optionally, such as Figure 2 and Figure 3 As shown, the first guide plate 31 and the second guide plate 32 are provided with an inner recess 311 at one end near the inner wall of the feed box 20. A torsion spring 312 is provided inside the inner recess 311 and is sleeved on the outside of the shaft of the rotating shaft 34.

[0033] In this embodiment, the first guide plate 31 and the second guide plate 32 have an inner recess 311 at one end near the inner wall of the feed box 20, and a torsion spring 312 inside the inner recess 311 is sleeved on the rotating shaft 34. When the material impacts the first guide plate 31 and the second guide plate 32 and causes them to rotate, the torsion spring 312 deforms and generates elastic force; after the material passes through, the elastic force of the torsion spring 312 drives the first guide plate 31 and the second guide plate 32 to return to their original positions.

[0034] Optionally, such as Figure 1 and Figure 3 As shown, flexible shielding plates 313 are connected to the upper surface of the first guide plate 31 and the second guide plate 32 near the inner wall of the feed box 20. One end of the flexible shielding plate 313 is connected to the inner wall of the feed box 20.

[0035] In this embodiment, flexible baffles 313 are connected to the upper surfaces of the first guide plate 31 and the second guide plate 32 near the inner wall of the feed box 20, with one end of the flexible baffle 313 connected to the inner wall of the feed box 20. When the first guide plate 31 and the second guide plate 32 rotate, the flexible baffle 313 deforms accordingly, always filling the gap between the first guide plate 31, the second guide plate 32 and the inner wall of the feed box 20. The flexible baffle 313 effectively prevents material from splashing from the gap between the first guide plate 31, the second guide plate 32 and the inner wall of the feed box 20, enhancing the splash prevention effect; its flexibility does not affect the normal rotation of the first guide plate 31 and the second guide plate 32, ensuring the flexibility of the device.

[0036] Optionally, such as Figure 2 and Figure 3 As shown, a Hall sensor 21 is connected to the outer surface of the feed box 20, and the Hall sensor 21 is connected to the rotating shaft 34 on the first guide plate 31.

[0037] In this embodiment, a Hall sensor 21 is connected to the outer surface of the feed box 20. The Hall sensor 21 is connected to the rotating shaft 34 on the first guide plate 31, and can detect parameters such as the rotation angle and speed of the rotating shaft 34 in real time, and convert these parameters into electrical signals and transmit them to the relevant control system. The operator can monitor the working status of the first guide plate 31 in real time through the control system. When the first guide plate 31 experiences abnormal rotation, jamming, or other problems, it can be detected and dealt with in a timely manner to prevent the fault from escalating and improve the reliability and safety of equipment operation.

[0038] Optionally, such as Figure 1 and Figure 2 As shown, the extended protection component 33 includes an extension plate 331 that is inserted into one end of the first guide plate 31 away from the inner wall of the feed box 20, and a permanent magnet 332 that is connected to one end of the extension plate 331 that extends to the first guide plate 31. An electromagnet 333 is provided on one side of the permanent magnet 332. The electromagnet 333 and the permanent magnet 332 are magnetically attracted to each other. The electromagnet 333 is connected to the inside of the first guide plate 31.

[0039] In this embodiment, the extended protection component 33 includes an extension plate 331 that is inserted into the end of the first guide plate 31 away from the inner wall of the feed box 20, and a permanent magnet 332 that is connected to the end of the extension plate 331 extending to the first guide plate 31. An electromagnet 333 is provided on one side of the permanent magnet 332. The electromagnet 333 and the permanent magnet 332 are magnetically attracted to each other. The electromagnet 333 is connected to the inside of the first guide plate 31. The Hall sensor 21 transmits the rotation information of the rotating shaft 34 on the first guide plate 31 to the PLC. The PLC controls the on / off state and current magnitude of the electromagnet 333 according to the rotation of the first guide plate 31. If the rotation angle is too large, it indicates that there is a lot of material or the material is too large. If the rotation angle is too small, the PLC controls the on / off state and current magnitude of the electromagnet 333 to change the magnetic force between the electromagnet 333 and the permanent magnet 332, thereby adjusting the extension length of the extension plate 331.

[0040] With the help of the PLC, Hall sensor 21 and electromagnet 333, the length of extension plate 331 can be automatically and flexibly adjusted according to the actual rotation of the first guide plate 31, so that the anti-splash and material guiding capabilities of the first guide plate 31 are always in the best state, and better adapt to materials of different quantities and sizes. This automated adjustment method is not only convenient and stable to operate, but also reduces manual intervention, further improving the adaptability, practicality and intelligence level of the device.

[0041] The specific operation method of this utility model is as follows:

[0042] The limestone material first enters the feed box 20 and falls onto the first guide plate 31. Since the first guide plate 31 and the second guide plate 32 are both inclined and form an angle of 30-45°, the material slides down to the second guide plate 32 at a buffered speed under the guidance of the first guide plate 31, and is then further guided by the second guide plate 32 into the crusher body 10 for crushing.

[0043] Under the impact of the material, the first guide plate 31 and the second guide plate 32 rotate around the rotating shaft 34, and the torsion spring 312 in the concave opening 311 deforms; after the material passes through, the elastic force of the torsion spring 312 causes the guide plate to return to its original position. At the same time, the flexible baffle 313 deforms as the guide plate rotates, always filling the gap between the guide plate and the inner wall of the feed box 20 to prevent material from splashing.

[0044] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
