Description

Technical Field

[0001] The present invention relates to the technical field of cone crushers, and more particularly to a large multi-cylinder hydraulic cone crusher. Background Art

[0002] The cone crusher adopts two sealing methods: dry oil or water, which prevents dust and impurities from entering the machine body, thereby ensuring the cleanliness of the lubricating oil, extending the service life of the sliding bearing and thrust ball bearing, and making the machine run reliably. This machine is mainly composed of a frame, transmission, hollow eccentric shaft, bowl-shaped bearing, crushing cone, adjustment device, adjustment sleeve, spring and hydraulic station for adjusting the discharge port. When the crusher is working, the motor drives the eccentric sleeve to rotate through the horizontal shaft and a pair of bevel gears. The axis of the crushing cone performs a rotary pendulum motion under the force of the eccentric sleeve, causing the surface of the crushing wall to sometimes approach and sometimes move away from the surface of the mortar wall, so that the ore is continuously squeezed and bent in the crushing chamber and crushed.

[0003] The shortcomings of the existing technology are: when the stone is crushed by the crushing wall and the mortar wall, the crushing wall swings periodically, so that the gap between the crushing wall and the mortar wall periodically increases and decreases, thereby achieving the effect of crushing the stone. However, there is still a certain difference in the volume of the crushed stone, and many stones will not be completely crushed. In the later use, the crushed stone needs to be screened, which makes the crushed stone effect poor and difficult to use directly without screening. For this reason, we propose a large multi-cylinder hydraulic cone crusher. Summary of the Invention

[0016] The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The large multi-cylinder hydraulic cone crusher involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] like Figure 1-11As shown, in one embodiment, a large multi-cylinder hydraulic cone crusher is proposed, including a lower shell 1, an upper shell 102 is installed on the upper end of the lower shell 1 through a hydraulic component 101, a discharge machine base 2 is installed in the lower shell 1, a crushing component 3 is arranged between the discharge machine base 2 and the upper shell 102, a discharge port 4 is opened on the surface of the discharge machine base 2, the discharge port 4 includes a fine material discharge port 401 and a coarse material discharge port 402, the fine material discharge port 401 and the coarse material discharge port 402 are both opened in the discharge machine base 2, the fine material discharge port 401 is provided with a screening mechanism 5, the screening mechanism 5 is provided. The sub-mechanism 5 includes a recessed groove 501, a connecting chute 506, a discharge chute 505, a fixed screening rod 502 and a dynamic screening rod 503. The recessed groove 501 is opened in the fine material discharge port 401, and multiple fixed screening rods 502 are equidistantly installed in the recessed groove 501. Multiple dynamic screening rods 503 are slidingly connected in the discharge machine base 2. The lower end of the dynamic screening rod 503 is fixedly connected with a connecting plate 504. The discharge chute 505 is opened in the coarse material discharge port 402. The connecting chute 506 is opened in the discharge machine base 2 and is connected with the discharge chute 505 and the recessed groove 501.

[0018] In actual application of the embodiment of the present invention, after the stone is transported into the crusher, the crushing assembly 3 is controlled to operate, and the crushing wall swings periodically, so that the gap between the crushing wall and the mortar wall is periodically enlarged and reduced, completing the crushing of the stone. When the crushed volume is smaller than the gap between the crushing wall and the mortar wall, it will fall downward onto the discharge machine base 2. Since the upper end surface of the discharge machine base 2 is provided with an inclined surface, and the fine material discharge port 401 and the coarse material discharge port 402 are both located at the lowest point of the inclined surface, at this time The crushed stones will fall into the fine material discharge port 401 which is currently in the open state, and then fall on the fixed screening rod 502 and the dynamic screening rod 503. At this time, the stones that do not meet the crushing volume standards can be intercepted between the fixed screening rod 502 and the dynamic screening rod 503, while the stones that meet the crushing volume standards will fall through the gap between the fixed screening rod 502 and the dynamic screening rod 503 and be intercepted by the fixed screening rod 502. The stones on 502 and the dynamic screening rod 503 can be pushed to both sides, so that the stones that do not meet the volume standards are pushed into the recessed groove 501, and then enter the discharge chute 505 through the connecting chute 506, and finally enter the coarse material discharge port 402 from the discharge chute 505 for discharge, thereby achieving the effect of filtering and screening the crushed stones, so that the stones discharged through the fine material discharge port 401 can be directly used to meet the standards. Since the crusher can adjust the volume of stone crushing, the height of the mortar wall in the upper shell 102 can be controlled to adjust the gap range between the mortar wall and the crushing wall, so that stones of different volumes can be crushed according to different needs. At this time, the connecting plate 504 can be controlled to rise and fall, driving the dynamic screening rod 503 to rise and fall, changing the distance between the fixed screening rod 502 and the fixed screening rod 502, thereby achieving the range of adjusting the stone volume screening, thereby achieving the adjustment of the crushed stone volume according to the equipment. The volume of the crushed stone filtration is synchronously adjusted.

[0019] like Figure 4-7 As shown, in one embodiment, a pair of reciprocating screws 6 are rotatably connected in the discharge machine base 2, and the circumferential surface of the reciprocating screw 6 is threadedly connected to a connecting seat 601, and the connecting seat 601 is provided with a plurality of conical push blocks 602, which are located between the fixed screening rod 502 and the dynamic screening rod 503.

[0020] When the embodiment of the present invention is actually applied, the reciprocating screw rod 6 is controlled to rotate, and the reciprocating screw rod 6 will drive the connecting seat 601 to move back and forth, and synchronously drive multiple conical pushing blocks 602 to move back and forth, pushing the stones intercepted between the fixed screening rod 502 and the dynamic screening rod 503. When the conical pushing block 602 moves to the front and rear sides, the intercepted stones can be pushed into the concave groove 501 and then fall into the connecting chute 506 for discharge and separation. Since both ends of the fixed screening rod 502 and the dynamic screening rod 503 are located in the concave groove 501, the fallen and crushed stones will not directly fall on the fixed screening rod 502 and the dynamic screening rod 503. The conical pushing block 602 moves to the extreme positions on both sides of the fixed screening rod 502 and the dynamic screening rod 503 to push out the stones that do not meet the crushing volume. This achieves the goal of preventing the falling stones from being pushed into the concave groove 501 by the conical pushing block 602 without being screened, providing time for the stone screening and filtering at the crushing port.

[0021] like Figure 7-9 As shown, in one embodiment, a plurality of slide rods 7 are slidably connected in the connecting seat 601, and the slide rods 7 are fixedly connected to the conical push block 602. A push plate 701 is installed at the lower end of the slide rod 7, and a spring 702 is installed between the push plate 701 and the connecting seat 601. A pair of driven rods 703 are rotatably connected in the discharge machine base 2, and a convex roller 704 is installed on the circumferential surface of the driven rod 703. The push plate 701 is slidably connected to the convex roller 704.

[0022] When the embodiment of the present invention is actually applied, the driven rod 703 is controlled to rotate, and the driven rod 703 drives the convex roller 704 to rotate. At this time, the convex roller 704 will push the push plate 701 to move upward. At the same time, through the cooperation of the spring 702 and the slide bar 7, the conical push block 602 can be driven to shake up and down. When the conical push block 602 moves back and forth to push the stone, the up and down shaking of the conical push block 602 promotes the movement of the stone falling between the fixed screening rod 502 and the dynamic screening rod 503, and there will be no accumulation and blockage of stones. This can ensure that the crushed stones that meet the standards are stably screened and fall, and at the same time, it can prevent some stones from being stuck between the fixed screening rod 502 and the dynamic screening rod 503, and push the crushed stones that do not meet the standards to both sides for discharge.

[0023] like Figure 4 and 7 As shown, in one embodiment, the output end of the driving motor 8 installed in the discharge machine base 2 is connected to one of the reciprocating screw rods 6, the reciprocating screw rods 6 are connected through a first sprocket set 801, and the reciprocating screw rods 6 and the driven rod 703 are connected through a second sprocket set 802.

[0024] When the embodiment of the present invention is actually applied, the operation of the driving motor 8 is controlled to drive the reciprocating screw 6 to rotate. Through the cooperation of the first sprocket group 801, the two reciprocating screws 6 are controlled to rotate, so that the conical push block 602 moves back and forth. At the same time, through the cooperation of the second sprocket group 802, the two driven rods 703 can be controlled to rotate, driving the conical push block 602 to shake up and down, thereby realizing the shaking of the conical push block 602 during the reciprocating movement back and forth. When the conical push block 602 pushes the stone to move to both sides, it can drive the nearby stone to shake, thereby promoting the downward discharge of the crushed stone that meets the standards.

[0025] like Figure 5-7 As shown, in one embodiment, a plurality of guide rods 9 are installed in the discharge machine base 2, and the guide rods 9 are all slidingly connected to the connecting plate 504. A threaded rod 901 rotatably connected in the discharge machine base 2 is threadedly connected to the connecting plate 504. A first rack 902 is slidingly connected in the discharge machine base 2, and the first rack 902 is engaged with a first gear 903 installed on the circumferential surface of the threaded rod 901.

[0026] When the embodiment of the present invention is actually used, since a plurality of guide rods 9 are provided in the machine base, the connecting plate 504 can be guided to move up and down. When the control rack slides in the discharge machine base 2, the rack will drive the first gear 903 to rotate, and the first gear 903 will drive the threaded rod 901 to rotate. At this time, the connecting plate 504 is driven to move up and down through the cooperation of the guide rod 9, so that the height position of the plurality of dynamic screening rods 503 installed on the connecting plate 504 is moved, and the gap between the dynamic screening rod 503 and the fixed screening rod 502 is adjusted. Since the crusher can change the volume of stone crushing by adjusting the gap between the crushing wall and the mortar wall in the crushing assembly 3, it can be adapted and adjusted according to the volume of stone crushed by the crusher, thereby achieving the effect of filtering stones of different volumes.

[0027] like Figure 4-7 As shown, in one embodiment, an electric push rod 904 is installed in the discharge machine base 2, and a connecting frame 905 is installed at the output end of the electric push rod 904, and the connecting frame 905 is fixedly connected to the first rack 902.

[0028] When the embodiment of the present invention is actually used, the electric push rod 904 is controlled to operate, and the electric push rod 904 will drive the connecting frame 905 to move, and the connecting frame 905 drives the rack to move, thereby achieving the effect of controlling the overall height position of the movable screening rod 503, adjusting the gap between it and the fixed screening rod 502, and meeting the effect of filtering stones of different volumes.

[0029] like Figure 2 and 4As shown, in one embodiment, a connecting shaft 10 rotates in the discharge machine base 2, and a sealing plate 1001 is installed on the circumferential surface of the connecting shaft 10, and the sealing plate 1001 is used to seal the top of the fine material discharge port 401 and the coarse material discharge port 402.

[0030] When the embodiment of the present invention is actually applied, the connecting shaft 10 is controlled to rotate, and the connecting shaft 10 will drive the sealing plate 1001 to rotate. At this time, the sealing plate 1001 will block one of the fine material discharge port 401 and the coarse material discharge port 402, and the stone crushed by the crushing component 3 is discharged through one of the discharge ports. During normal crushing, the sealing plate 1001 blocks the coarse material discharge port 402, and the crushed stone passes through the fine material discharge port 401. When the crushing component 3 crushes the stone load, the hydraulic component 101 is in operation, driving the upper shell 102 to move upward, so that a larger gap is generated between the crushing wall and the mortar wall, so that the uncrushed stone is discharged, and then the equipment load state is released. At this time, the unfinished stone will fall into the coarse material discharge port 402 to achieve a separation effect, avoiding mixing with the crushed stone.

[0031] like Figure 12-14 As shown, in one embodiment, a guide frame 1002 is installed at the upper end of the lower shell 1, and the circumferential surface of the guide frame 1002 is slidably connected to a connecting block 1003, and a second rack 1004 is installed on the surface of the connecting block 1003, and the second rack 1004 is engaged with a second gear 1005 installed on the circumferential surface of the connecting shaft 10, and a connecting rod 1006 is installed on the circumferential surface of the upper shell 102, and the connecting rod 1006 is slidably connected to the connecting block 1003, and a tension spring 1007 is installed between the connecting rod 1006 and the connecting block 1003.

[0032] In actual application of the embodiment of the present invention, when the hydraulic assembly 101 is operated to drive the upper shell 102 to move upward, so that a larger gap is generated between the crushing wall and the mortar wall, the upper shell 102 will drive the connecting rod 1006 to move upward. At this time, through the cooperation of the tension spring 1007, the connecting rod 1006 will drive the connecting block 1003 and the second rack 1004 to move upward. The second rack 1004 will drive the second gear 1005 to rotate, and the second gear 1005 will drive the connecting shaft 10 to rotate, thereby controlling the blocking plate 1001 to block the coarse material discharge port 402. The falling stones will fall into the coarse material discharge port 402 and be discharged. Since a tension spring 1007 is installed between the connecting block 1003 and the connecting rod 1006, when the hydraulic component 101 drives the upper shell 102 to move upward, the rotation angle of the sealing plate 1001 and the connecting shaft 10 is limited. This can avoid motion interference when the hydraulic component 101 drives the upper shell 102 to move upward too much. When the connecting shaft 10 drives the connecting block 1003 and the second rack 1004 to move upward through the connection of the tension spring 1007, there is a certain extension adaptation space.
