Technical Field
[0001] This utility model relates to the technical field of ore processing equipment, and more specifically, to an ore crushing device for mining. Background Technology
[0002] Crushing equipment for mining is an indispensable and important piece of equipment in the mining and ore processing process. It is used to crush large blocks of ore into smaller pieces to meet the requirements of subsequent processes such as mineral processing, grinding, transportation, and smelting. The toothed roll crusher is a common type of mining crushing equipment. The toothed roll crusher relies on two relatively rotating toothed rolls to crush materials. When the material enters the crushing chamber between the two toothed rolls, the teeth on the rolls mesh with each other, squeezing, splitting, and breaking the material. For larger pieces of material, the teeth on the rolls first bite them, and then, through the relative rotation of the two rolls, the material is crushed into smaller pieces under the pressure of the teeth. As the toothed rolls continue to rotate, the smaller pieces of material are further crushed and ground until their particle size meets the set requirements and is discharged from the gap between the toothed rolls. Since crushed ore may fly off during the crushing process, it is necessary to carry out crushing protection operations.
[0003] In related technologies, during the use of crushers, a semi-enclosed protective frame is generally installed on the top of the crusher's feed hopper to block and protect the crushed stones during the crushing process.
[0004] However, in the current use of crushers, the protective frames are generally of fixed size, while the feed space requirements for ore crushing vary with the size of the ore being processed. This makes it difficult for the protective frames to adapt to the protection requirements of different sized ore feeds, affecting the protective flexibility and adaptability of the crusher.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Reference Figures 1-4 This utility model provides a technical solution: a mining ore crushing equipment, including a crusher body 1 and a protective extension mechanism. Crushing rollers 2 are installed on both sides inside the crusher body 1, and a protective frame 3 is installed on the top of the crusher body 1. This provides the user with a medium to adjust the size of the feed inlet of the protective frame 3 according to the external ore crushing and feeding requirements, and to extend the protection range of the protective frame 3. This avoids the situation where it is difficult to adjust the protective feed when the protective frame 3 is in use, thus improving the crushing protection feed flexibility and adaptability of the protective frame 3.
[0031] Reference Figures 1-4 In a preferred embodiment, the protective extension mechanism includes a protective net 4, which is movably connected to both sides of the protective frame 3. An extension frame 5 is movably connected to the outer side of the protective frame 3. The outer side of the protective net 4 is fixedly connected to the inner side of the extension frame 5. A protective opening 6 is opened on the front side of the top of the extension frame 5. A protective plate 7 located at the bottom of the protective opening 6 is movably connected to the front side of the interior of the extension frame 5. An extension connection mechanism is fixedly connected to both sides of the front side of the extension frame 5. According to the actual crushing and feeding requirements of the external ore, by holding the extension frame 5 and moving it upward, the feeding point on the front side of the protective frame 3 can be expanded. At the same time, the outer perimeter of the protective frame 3 is also expanded. The protection range is extended to ensure that the protective frame 3 can extend the protection for the ore crushed by the crushing roller 2. The extension connection mechanism includes a connecting seat 8, a connecting groove 9, and a connecting block 10. The connecting seat 8 is fixedly connected to both sides of the front side of the extension frame 5. The connecting groove 9 is opened on the inner side of the rear side of the connecting seat 8. The connecting block 10 is movably connected to the top inside the connecting groove 9. The rear side of the connecting block 10 is fixedly connected to the front side of the protective frame 3. This allows for the extension and lifting connection between the extension frame 5 and the protective frame 3, while preventing positional deviation during the adjustment of the extension frame 5. Therefore, the stability of the extension adjustment of the extension frame 5 is improved.
[0032] Reference Figures 2-3In a preferred embodiment, a protective strip 11 is movably connected to the bottom of the rear side of the extension frame 5. A protective belt 12 located inside the protective opening 6 is fixedly connected to the top of the protective strip 11. The bottom of the protective belt 12 is fixedly connected to the top of the protective plate 7. This provides a medium for extending the protection of the protective plate 7, preventing the protective plate 7 from being too high after the extension frame 5 is raised, making it difficult to continue feeding protection of the front side of the protective frame 3 and the extension frame 5. This improves the flexibility of the protective plate 7. Lifting openings 13 are provided on both sides of the front side of the protective strip 11. A lifting frame 14 is movably connected inside the lifting opening 13. The front side of the lifting frame 14 is fixedly connected to the rear side of the extension frame 5, which can perform lifting and lowering connection between the protective strip 11 and the extension frame 5, preventing the protective strip 11 from shifting position during use. This improves the stability of the protective strip 11 during use.
[0033] Reference Figures 2-3 In a preferred embodiment, magnetic plates 15 are embedded and connected to both sides of the rear side of the inner wall of the extension frame 5, and magnetic suction plates 16 connected to the magnetic plates 15 are embedded and connected to both sides of the rear side of the protective frame 3. This allows for pre-positioning of the extension frame 5 and the protective frame 3 after adjustment, avoiding difficulties in pre-positioning the extension frame 5 during use and preventing inconvenience in subsequent operations. This improves the ease of use of the extension frame 5. Magnetic suction pieces 17 are embedded and connected to both sides of the front side of the protective strip 11. The front side of the magnetic suction pieces 17 is magnetically connected to the rear side of the magnetic plates 15. The magnetic plates 15 can be used to magnetically position the protective strip 11 after operation, thus improving the ease of use of the protective strip 11.
[0034] Reference Figures 2-3 In a preferred embodiment, an operating port 18 is provided at the bottom of the protective strip 11, and a screw cylinder 19 located inside the operating port 18 is fixedly connected to the bottom of the rear side of the extension frame 5. A stud 20 is threadedly connected inside the screw cylinder 19, which can provide the user with a medium for stable positioning between the extension frame 5 and the protective frame 3, thus improving the convenience of adjusting and positioning the extension frame 5. A force application port 21 connected to the screw cylinder 19 is provided at the bottom of the rear side of the extension frame 5. A force application plate 22 is movably connected inside the force application port 21. The rear side of the force application plate 22 is fixedly connected to the front side of the stud 20, which can expand the clamping force application range of the stud 20 and perform anti-slip work, thus improving the force application and positioning effect of the stud 20.
[0035] Specifically, the working process or working principle of this mining ore crushing equipment is as follows: During use, when the crushing feed range in front of the protective frame 3 needs adjustment, first, hold the protective strip 11 to move the protective belt 12 upwards. At this time, because the protective belt 12 is made of flexible rubber, the protective plate 7 moves upwards from the rear of the protective belt 12, causing the front of the protective belt 12 to move downwards, preparing for subsequent protection of the feed space in front of the protective frame 3 and the extension frame 5. Simultaneously, the lifting frame 14 moves inside the lifting port 13, protecting the protective plate 7 and the extension frame. The extension frame 5 is connected by a lifting mechanism. During this process, the magnetic plate 17 moves with the protective strip 11. The magnetic plate 15 magnetically positions the protective plate 7 and the extension frame 5 after the extension frame moves upward. The screw threaded to the rear of the protective strip 11 can also be used to secure the protective strip 11 and the extension frame 5 together. Then, the extension frame 5 is held in place, causing the connecting seat 8 to move upward. At this time, the connecting block 10 moves inside the connecting groove 9, connecting the extension frame 5 and the protective frame 3. Simultaneously, the magnetic strip moves with the extension frame. The frame 5 moves via the magnetic suction plate 16 to perform magnetic pre-positioning between the adjusted extended frame 5 and the protective frame 3. Then, the hand-held stud 20 rotates in conjunction with the screw cylinder 19 to apply a forward-moving threaded force to the force-applying plate 22, causing the front of the force-applying plate 22 to contact and abut against the rear of the protective frame 3. This applies force and positions the adjusted extended frame 5 and the protective frame 3, allowing the extended frame 5, in conjunction with the protective net 4, to expand the feeding space in front of the protective frame 3 and extend the protective range around the protective frame 3. When the external ore conveyor... When the ore is conveyed into the crusher body 1 and comes into contact with the crushing roller 2, the ore passes through the feed space in front of the protective frame 3 and the extension frame 5 and enters the crusher body 1 to come into contact with the crushing shaft. At this time, since the protective plate 7 is flexibly connected to the extension frame 5 through the protective belt 12, it protects the feed space in front of the protective frame 3 and the extension frame 5 while ensuring that the external ore can enter, preventing ore fragments from flying out through the feed area in front of the protective frame 3 and the extension frame 5, and ensuring the protective effect of the protective frame 3 and the extension frame 5 on the feed crushing of the crusher body 1.
[0036] It should be noted that the crusher body 1, crushing roller 2 and protective frame 3 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
