The annular groove on the outer wall of the crushing chamber and the internal components constitute a protective system. Multiple fixed hollow plates are equidistantly distributed in the annular groove. Hollow rods fixed on the upper and lower sides of the fixed hollow plates provide support for the buffer structure. The springs inside the hollow rods have an elastic buffering function. When the equipment vibrates during operation or is impacted by external forces, the moving column fixedly connected to one end of the spring will move under the extension and contraction of the spring. The moving column drives the arc plate to move synchronously. The arc plate slides along the annular grooves opened on the upper and lower sides of the inner ring plate, forming a flexible protection for the outer wall of the crushing chamber, effectively reducing the damage of external forces to the shell.

The drive bevel gear meshes with the bottom of the toothed ring rotatably connected to the inner side of the hollow column. Thus, the rotational motion of the drive bevel gear is transmitted to the toothed ring, causing the toothed ring to rotate stably inside the hollow column. The crusher fixed on the top of the toothed ring rotates at high speed under the drive of the toothed ring.

[0013] As a further description of the above technical solution:

[0014] A switch is fixedly connected to the top front side of the base, and the switch is electrically connected to the nozzle.

[0023] Each of the hollow rods has a sliding groove on both sides inside, and each of the movable columns has a slider fixedly connected to both sides at one end. The sliders are slidably connected to the interior of the corresponding sliding groove.

[0024] The above technical solution ensures that when the equipment is subjected to vibration or external impact, the spring extension drives the moving column to move, and the slider slides along the slide groove, ensuring that the moving column can only move in a straight line in a predetermined direction.

[0025] As a further description of the above technical solution:

[0026] A baffle is fixedly connected to the top of the crushing chamber, and the size of the baffle matches that of the feed inlet.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the drive shaft of the cone crusher drives the drive bevel gear, gear ring and crusher to rotate, and crushes the raw materials in the crushing chamber. When the outer wall of the crushing chamber is impacted, the ring plate is squeezed, which causes the moving column to squeeze the spring into the hollow rod to absorb the impact force. When the impact force is too large, the ring plate will rotate to relieve the force, thus achieving flexible protection of the outer wall of the crushing chamber, reducing external damage and ensuring the long-term stable operation of the equipment.

[0030] 2. In this utility model, the external cleaning fluid supply system is activated and the liquid is delivered to the nozzle, thus realizing the supply of cleaning fluid.

[0038] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a cone crusher housing protective structure, including a base 1. The base 1 serves as the foundation of the entire equipment, providing stable support for the upper structure. A hollow column 3 is fixedly connected to the top of the base 1. The hollow column 3 is not only a vertical connecting component of the structure, but also has a power assembly on its front side, enabling efficient crushing operations. A crushing chamber 8 is fixedly connected to the top of the hollow column 3. The crushing chamber 8 provides a closed space for material crushing. A feed inlet 9 is opened at the top of the crushing chamber 8, serving as the channel for materials to enter the crushing chamber 8, facilitating crushing. Material is smoothly fed in. An annular groove 10 is provided on the outer wall of the crushing chamber 8. This groove provides space for the installation of subsequent protective structures. Multiple fixed hollow plates 12 are equidistantly fixed inside the annular groove 10. These fixed hollow plates 12 provide stable support for the buffer protective structure and disperse external impact. Hollow rods 13 are fixedly connected to the upper and lower sides of each of the fixed hollow plates 12. These hollow rods 13 guide the extension and retraction of springs 14. Springs 14 are fixedly connected inside each of the hollow rods 13, reducing impact when the equipment vibrates or is subjected to external forces. The other ends of the springs 14 are fixed... Multiple movable columns 15 are connected and move flexibly under the action of springs 14. One end of each movable column 15 is fixedly connected to an arc-shaped plate 16, which fits against the outer wall of the crushing chamber 8 to directly resist external forces and protect the shell. One side of each arc-shaped plate 16 is slidably connected to the same annular plate 17, which limits the sliding trajectory of the arc-shaped plates 16. The annular plate 17 has annular grooves 18 on its upper and lower sides to guide the movement of the arc-shaped plates 16. A cleaning mechanism 2 is provided at the top of the crushing chamber 8 to clean the feed inlet 9 and its surroundings to prevent material from entering the chamber. The power assembly includes a drive shaft 4, which serves as the starting component for power input, receiving and transmitting external power. The rear end of the drive shaft 4 passes through the front side of the hollow column 3 and is fixedly connected to a drive bevel gear 5. A gear ring 6 is rotatably connected to the inner side of the hollow column 3. A crusher 7 is fixedly connected to the top of the gear ring 6. The crusher 7 powerfully crushes the input material. A baffle 11 is fixedly connected to the top of the crushing chamber 8. The baffle 11 can prevent foreign objects from accidentally falling into the feed inlet 9. The size of the baffle 11 matches that of the feed inlet 9, ensuring the protective effect without affecting the smoothness of feeding.

[0040] Specifically, when the external power drives the drive shaft 4 to rotate, the drive bevel gear 5 rotates synchronously, causing the gear ring 6 to rotate stably within the hollow column 3. The crusher 7, fixed to the top of the gear ring 6, rotates at high speed under the drive of the gear ring 6, crushing the raw material in the crushing chamber 8. Its top feed inlet 9 is the channel for material entry; the material to be crushed is fed in through this point. The annular groove 10 on the outer wall of the crushing chamber 8 and its internal components constitute a protective system. Multiple fixed hollow plates 12 are equidistantly distributed within the annular groove 10. Hollow rods 13 fixed on the upper and lower sides of the fixed hollow plates 12 provide support for the buffer structure. The hollow rods 13... The spring 14 of the part has an elastic buffer function. When the equipment vibrates or is impacted by external force during operation, the moving column 15, which is fixedly connected to one end of the spring 14, will move under the extension and contraction of the spring 14. The moving column 15 drives the arc plate 16 to move synchronously. The arc plate 16 slides along the annular groove 18 opened on the upper and lower sides of the inner ring plate 17 to ensure the stability of the movement of the arc plate 16, forming a flexible protection for the outer wall of the crushing chamber 8, effectively reducing the damage of external force to the shell, ensuring the long-term stable operation of the cone crusher, and preventing foreign objects from accidentally falling into the feed inlet 9, preventing foreign objects from entering the crushing chamber 8 and damaging the crusher 7.

[0041] Reference Figure 2 The cleaning mechanism 2 includes an arc plate 201, which can gather materials and provide a base for subsequent components. Multiple U-shaped frames 202 are fixedly connected at equal intervals to the bottom of the arc plate 201. The U-shaped frames 202 are used to install and support the components below, ensuring that they are in the right position during operation. The bottom of each U-shaped frame 202 is rotatably connected to a rotating shaft 203. The rotating shaft 203 can rotate flexibly, causing the connected components to change angles to adapt to different cleaning needs. Rotating blocks 204 are fixedly connected to the outer walls of each rotating shaft 203. The rotating blocks 204 rotate with the rotating shaft 203, thereby adjusting the direction of the nozzle 205. The bottom of each rotating block 204 is fixedly connected to a nozzle 205, which is used to spray cleaning fluid.

[0042] Specifically, when the external cleaning fluid supply system is started and the liquid is delivered to the nozzle 205 through the pipeline, the nozzle 205 is connected to the rotating shaft 203 through the rotating block 204. The angle of the nozzle 205 can be changed by rotating the rotating shaft 203 to achieve multi-directional rotation, so that the cleaning fluid can be sprayed at different angles to the feed inlet 9 and its surrounding area.

[0043] Reference Figure 1 , Figure 4 and Figure 5The base 1 has a switch 19 fixedly connected to its top front side. The switch 19 controls the start and stop of the entire equipment. It is electrically connected to the nozzle 205, allowing the operator to easily control whether the nozzle 205 sprays cleaning fluid. The hollow column 3 has multiple tripods 20 fixedly connected at equal intervals on its lower outer wall. The tripods 20 enhance the stability of the hollow column 3, ensuring it stands firmly on the base 1. The bottoms of the multiple tripods 20 are fixedly connected to the top of the base 1, further reinforcing the connection between the hollow column 3 and the base 1. A support frame 21 is fixedly connected to the bottom of the base 1, which serves to lift... The high base 1 serves to prevent damage that may occur if the base 1 and the entire device come into direct contact with the ground. The bottom of the support frame 21 is fixedly connected to the base plate 22, which increases the contact area with the ground and makes the device more stable. Multiple hollow rods 13 serve as guide structures for moving parts. Slide grooves 23 are provided on both sides of the inside of the rods. The slide grooves 23 provide sliding tracks for the sliders 24. Multiple moving columns 15 have sliders 24 fixedly connected to both sides of one end. The sliders 24 are slidably connected to the inside of the corresponding slide grooves 23, so that the moving columns 15 can move back and forth smoothly within the hollow rods 13.

[0044] Specifically, the nozzle 205 is controlled to open and close. The operator can easily start the cleaning mechanism 2 by operating the switch 19, so that the nozzle 205 sprays the cleaning liquid at the appropriate time, strengthens the connection between the hollow column 3 and the base 1, disperses the pressure and vibration generated during the operation of the equipment, and prevents the hollow column 3 from tilting or shaking due to uneven force. When the equipment is subjected to vibration or external impact, the spring 14 extends and retracts to drive the moving column 15 to move, and the slider 24 slides along the slide groove 23 to ensure that the moving column 15 can only move in a straight line in the predetermined direction.

[0045] Working Principle: When using the protective structure of the cone crusher shell, when the external power drives the drive shaft 4 to rotate, the drive bevel gear 5 rotates synchronously, driving the gear ring 6 to rotate stably within the hollow column 3. The crusher 7, fixed on the top of the gear ring 6, rotates at high speed under the drive of the gear ring 6, crushing the raw material with the crushing chamber 8. The top feed inlet 9 is the channel for material entry, and the material to be crushed is fed in from here. Multiple fixed hollow plates 12 are equidistantly distributed in the annular groove 10. The hollow rods 13 fixed on the upper and lower sides of the fixed hollow plates 12 provide support for the buffer structure. The springs 14 inside the hollow rods 13 have an elastic buffering function. When the equipment vibrates during operation or is subjected to external impact, the springs 14 are fixedly connected to one end of the springs 14. The movable column 15 moves under the extension and retraction of the spring 14. The movable column 15 drives the arc plate 16 to move synchronously. The arc plate 16 slides along the annular groove 18 opened on the upper and lower sides of the inner ring plate 17 to ensure the stability of the movement of the arc plate 16, forming a flexible protection for the outer wall of the crushing chamber 8, effectively reducing the damage of external forces to the shell, and ensuring the long-term stable operation of the cone crusher. When the external cleaning fluid supply system is started, the liquid is transported to the nozzle 205 through the pipeline. The nozzle 205 is connected to the rotating shaft 203 through the rotating block 204. The angle of the nozzle 205 can be changed by rotating the rotating shaft 203 to achieve multi-directional rotation, so that the cleaning fluid can be sprayed at different angles to the feed inlet 9 and its surrounding area.
