Description

Technical Field

[0001] The invention relates to the technical field of cone crushers, in particular to an anti-clogging cone crusher for mining. Background Art

[0002] Cone crusher is a commonly used mechanical equipment in mining, building materials and other fields. It is specially used for crushing materials such as ore and rock. It uses the eccentric shaft as the core driving component to drive the movable cone to perform regular rotational and pendulum motion. The distance between the movable cone and the fixed cone continuously changes. After the material enters between the two cones, it will be subjected to strong squeezing, bending and shearing forces. Under the combined action of these forces, the material is gradually crushed to a particle size that meets production requirements.

[0003] When the existing cone crusher is in operation, the eccentric structure drives the movable cone to rotate and swing, and cooperates with the fixed cone to crush materials. In actual operation, when the cone crusher is started to crush stones, if the operator puts a large amount of stones into the crushing chamber at the same time, the crusher has limited crushing processing capacity per unit time, and a large amount of stones rushing in instantly will exceed its normal crushing load. At this time, the stones cannot be crushed and discharged in the crushing chamber in time, and will continue to accumulate. As the accumulation amount increases, the internal space of the equipment is occupied, the flow of materials is blocked, and it is easy to cause blockage inside the equipment. Once blockage occurs, the operation of the crusher is hindered, and problems such as jamming and damage will occur, affecting normal production. For this reason, we propose an anti-blocking cone crusher for mining to solve this problem. Summary of the Invention

[0011] In some embodiments, the feed member further includes a support plate fixedly connected to the top of a plurality of support rods, the bottom of the support plate is fixedly connected to a second motor, the driving end of the second motor is fixedly connected to a stirring wheel, the top of the feed ring is fixedly connected to a top cylinder, and the stirring wheel is arranged in the top cylinder (599).

[0012] In some embodiments, the feed rings and feed troughs are provided in multiple groups, the multiple groups of feed rings are combined and connected to form a complete circle, and the multiple feed troughs correspond to the gaps between the multiple groups of fixed cones and the moving cones respectively.

[0013] In some embodiments, a discharge assembly is provided at the bottom of the base plate, and a push ring is provided inside the discharge assembly for pushing out stones.

Since the feed chute and the fixed cone are set in multiple groups, the stone can be divided into multiple groups to avoid blockage caused by all input. In short, blockage can be prevented by dividing the material; 2. When the moving cone contacts and crushes the fixed cone at the corresponding position, its buffer ring contacts the fixed cone synchronously, which also plays a role in crushing. At the same time, it can drive the plunger to move. The plunger squeezes the spring to play a buffering role. At the same time, the plunger drives the induction block to move. When the induction block is triggered, it will start the hydraulic rod at the corresponding position, drive the arc plate to move, open the opening of the feed chute, and discharge the material for crushing. At this time, the arc plates at other positions do not move, and the opening of the feed chute is closed, which can avoid feeding and crushing at the same time, which may cause blockage. In short, it can avoid blockage caused by simultaneous input. 3. Start the electric push rod, which drives the rotating rod to rotate. After the rotating rod rotates to the right position, it drives the fixed cone to rotate. Then the gap between the fixed cone and the moving cone can be adjusted, thereby adjusting the degree of crushing. 4. Start the third motor, which drives the gear to rotate, thereby driving the ring gear to rotate, and then driving the push plate to rotate. The push plate then drives the crushed stones to rotate. During the rotation process, they will be guided and discharged by the guide plate to avoid blockage; 5. When the moving cone rotates and moves, it will collide with the inner side of the feed ring. Through the collision, the stone can be further knocked down to avoid blocking the feed chute. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0019] See also Figures 1-8 , the present invention provides a technical solution: A cone crusher for mining with an anti-clogging function includes a frame 1, a ring body 2 and a bottom plate 3 fixedly connected to the frame 1, the bottom plate 3 being disposed at the bottom of the ring body 2, and a support block 4 fixedly connected to the bottom of the ring body 2. Because a top plate 54 and a buffer ring 581 are supported and limited by the support block 4, the top plate 54, the buffer ring 581, and the movable cone 55 can be driven to move and contact the fixed cone 573 at the corresponding position to crush stone; The crushing assembly 5 is arranged in the ring body 2. The crushing assembly 5 includes a chassis 51 arranged in the ring body 2. A turntable 52 is rotatably connected in the chassis 51. A first motor 53 is fixedly connected to the bottom of the bottom plate 3. The driving end of the first motor 53 is fixedly connected to the eccentric position of the turntable 52. A top plate 54 is fixedly connected to the top of the bottom plate 3. A moving cone 55 is fixedly connected to the top of the top plate 54. A plurality of grooves 56 are provided in the top plate 54. The bottom of the top plate 54 is supported by the supporting block 4. A matching piece 57 and a buffer piece 58 are provided in the frame 1. The crushing assembly 5 also includes a feeding piece 59 provided on the top of the frame 1. like Figure 5 As shown, the fitting 57 includes an electric push rod 571 fixedly connected to the top of the ring body 2. The bottom end of the electric push rod 571 passes through the ring body 2 and is rotatably connected to a rotating rod 572. A fixed cone 573 is rotatably connected to the inner side of the ring body 2. The bottom of the fixed cone 573 is rotatably connected to the rotating rod 572. Start the electric push rod 571, which drives the rotating rod 572 to rotate. After the rotating rod 572 rotates to the right position, it drives the fixed cone 573 to rotate, and then the gap between the fixed cone 573 and the dynamic cone 55 can be adjusted, thereby adjusting the degree of crushing. The matching pieces 57 are arranged in multiple groups, and the multiple groups of matching pieces 57 are arranged around the central axis of the ring body 2. The multiple fixed cones 573 are all arranged in a bent arc shape, which is arranged in an arc shape to facilitate crushing; like Figure 3 and Figure 4 As shown, the buffer member 58 includes a buffer ring 581 disposed on the outside of the top plate 54. An insert rod 582 is fixedly connected to the inside of the buffer ring 581. One end of the insert rod 582 extends into the groove 56 and is fixedly connected to the sensing block 583. A spring 584 is provided on the outer sleeve of the insert rod 582. The sensing block 583 is a motion sensing block. Once the sensing block 583 senses movement, it will immediately drive the hydraulic rod 594. The sensing block 583 is a prior art and will not be described in detail here. like Figure 5 、 Figure 6 and Figure 7 As shown, the feed member 59 includes a plurality of support rods 591 fixedly connected to the top of the frame 1, a feed ring 592 is fixedly connected between the plurality of support rods 591, a feed trough 593 is defined in the feed ring 592, a hydraulic rod 594 is fixedly connected to the outside of the feed ring 592, and the driving end of the hydraulic rod 594 passes through the feed trough 593 and is fixedly connected to an arc plate 595; The feed member 59 further includes a support plate 596 fixedly connected to the top of the plurality of support rods 591. A second motor 597 is fixedly connected to the bottom of the support plate 596. A stirring wheel 598 is fixedly connected to the driving end of the second motor 597. A top cylinder 599 is fixedly connected to the top of the feed ring 592. The stirring wheel 598 is disposed inside the top cylinder 599. When the movable cone 55 contacts and crushes the fixed cone 573 at the corresponding position, its buffer ring 581 contacts the fixed cone 573 synchronously, which also plays a role in crushing. At the same time, it can drive the insertion rod 582 to move. The insertion rod 582 squeezes the spring 584, which can play a buffering role. At the same time, the insertion rod 582 drives the induction block 583 to move. When the induction block 583 is triggered, it will start the hydraulic rod 594 at the corresponding position, driving the curved plate 595 to move, opening the opening of the feed chute 593, so that the material can be discharged for crushing. At this time, the curved plates 595 at other positions do not move, and the opening of the feed chute 593 is closed, which can avoid feeding and crushing at the same time, which may cause blockage. The feed rings 592 and the feed troughs 593 are provided in multiple groups. The multiple groups of feed rings 592 are combined and connected to form a complete circle. The multiple feed troughs 593 correspond to the gaps between the multiple groups of fixed cones 573 and the moving cones 55. It should be noted that when the moving cone 55 rotates and moves, it will collide with the inner side of the feed ring 592. Through the collision, the stones can be further knocked down to avoid blocking the feed trough 593.

[0020] During use, stones fall into the feed ring 592 and the feed chute 593, and then the first motor 53 is started, which drives the turntable 52 to rotate eccentrically, thereby driving the bottom plate 51 to move. Since the top plate 54 and the buffer ring 581 are supported and limited by the support block 4, the top plate 54, the buffer ring 581 and the movable cone 55 can be driven to move and contact with the fixed cone 573 at the corresponding position to crush the stones. Since the feed chute 593 and the fixed cone 573 are arranged in multiple groups, the stones can be divided into multiple groups to avoid blockage caused by all input; When the moving cone 55 contacts and crushes the fixed cone 573 at the corresponding position, its buffer ring 581 contacts the fixed cone 573 synchronously, which also plays a role in crushing. At the same time, it can drive the insertion rod 582 to move. The insertion rod 582 squeezes the spring 584, which can play a buffering role. At the same time, the insertion rod 582 drives the sensing block 583 to move. When the sensing block 583 is triggered, it will start the hydraulic rod 594 at the corresponding position, drive the arc plate 595 to move, and open the opening of the feed chute 593, so that the material can be discharged for crushing. At this time, the arc plates 595 at other positions have not moved, and the opening of the feed chute 593 is closed, which can avoid simultaneous feeding and crushing, which may cause blockage. Example 2

[0021] See also Figures 1-8 , the present invention provides a technical solution: Different from the first embodiment, the feed member 59 includes a plurality of support rods 591 fixedly connected to the top of the frame 1, a feed ring 592 fixedly connected between the plurality of support rods 591, a feed trough 593 is defined in the feed ring 592, a hydraulic rod 594 is fixedly connected to the outside of the feed ring 592, and the driving end of the hydraulic rod 594 penetrates into the feed trough 593 and is fixedly connected to an arc plate 595; The stones are fed into the top cylinder 599 and then the third motor 65 is started. The third motor 65 drives the stirring wheel 598 to rotate and then mixes the stones evenly to avoid blockage. The feed member 59 further includes a support plate 596 fixedly connected to the top of the plurality of support rods 591. A second motor 597 is fixedly connected to the bottom of the support plate 596. A stirring wheel 598 is fixedly connected to the driving end of the second motor 597. A top cylinder 599 is fixedly connected to the top of the feed ring 592. The stirring wheel 598 is disposed in the top cylinder 599. The top of the top cylinder 599 is expanded outward to increase the input area. When the movable cone 55 contacts and crushes the fixed cone 573 at the corresponding position, its buffer ring 581 contacts the fixed cone 573 synchronously, which also plays a role in crushing. At the same time, it can drive the insertion rod 582 to move. The insertion rod 582 squeezes the spring 584, which can play a buffering role. At the same time, the insertion rod 582 drives the induction block 583 to move. When the induction block 583 is triggered, it will start the hydraulic rod 594 at the corresponding position, driving the curved plate 595 to move, opening the opening of the feed chute 593, so that the material can be discharged for crushing. At this time, the curved plates 595 at other positions do not move, and the opening of the feed chute 593 is closed, which can avoid feeding and crushing at the same time, which may cause blockage. The feed rings 592 and the feed troughs 593 are provided in multiple groups. The multiple groups of feed rings 592 are combined and connected to form a complete circle. The multiple feed troughs 593 correspond to the gaps between the multiple groups of fixed cones 573 and the moving cones 55. like Figure 8 As shown, a discharge assembly 6 is provided at the bottom of the bottom plate 3, and a push ring 63 is provided inside the discharge assembly 6 for pushing out the stone; The discharging assembly 6 includes a bottom cylinder 61 fixedly connected to the top of the bottom plate 3, and the top of the bottom cylinder 61 is fixedly connected to a circular frame 62, and one side of the circular frame 62 is opened. The inner bottom of the circular frame 62 is rotatably connected to a push ring 63, and the bottom of the push ring 63 extends out of the bottom of the circular frame 62 and is fixedly connected to a gear ring 64. The top of the bottom plate 3 is fixedly connected to a third motor 65, and the driving end of the third motor 65 is fixedly connected to a gear 66. The gear 66 meshes with the gear ring 64, and a guide plate 67 is fixedly connected inside the circular frame 62. The third motor 65 drives the gear 66 to rotate, thereby driving the gear ring 64 to rotate, thereby driving the push ring 63 to rotate, and the push ring 63 thereby drives the crushed stone to rotate. Since the friction force on the top of the push ring 63 is large, the crushed stone can be driven to rotate. It should be noted that the discharging assembly 6 is tilted as a whole, which can further accelerate the speed of stone discharge.

[0022] Start the third motor 65, and the third motor 65 drives the gear 66 to rotate, thereby driving the ring gear 64 to rotate, and then driving the push ring 63 to rotate. The push ring 63 drives the crushed stone to rotate. During the rotation, it will be guided and discharged by the guide plate 67 to avoid blockage.
