Abstract
Description
Technical Field
[0001] This utility model relates to the field of ore crushing technology, and more specifically, to an ore crushing machine with good grinding effect. Background Technology
[0002] A ore crusher, also known as a rock crusher, is a type of equipment widely used in the mining industry. It is mainly used to crush large ores into smaller particles for subsequent processing and treatment.
[0003] Traditional ore crushers have the following shortcomings: First, the size and uniformity of the feed directly affect the crushing effect. If the feed is too large or uneven, the jaw plates may not be able to effectively crush all the material, resulting in some material not being fully crushed. Second, the geometry of the crushing chamber and the adjustment of the discharge port also affect the crushed particle size. When the discharge port is large, the material passage speed will be slower, but if the material distribution in the crushing chamber is uneven, some material may also not be fully crushed; if these larger particles are not subjected to secondary crushing, it may negatively affect the operating efficiency of the entire production line and product quality. Larger particles may not be able to pass smoothly through subsequent grinding and beneficiation processes, thus affecting the operating efficiency of the entire production line; therefore, improvements are needed. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a crusher with good grinding effect, which has the advantage of good grinding effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a crusher with good grinding effect, comprising a shell, an inlet at the top of the shell, two baffles fixedly installed at the bottom of the shell, a discharge port one between the baffles and the inner side of the shell, a discharge port two between the inner sides of the two baffles, a screening plate fixedly installed above the discharge port one between the top of the baffles and the inner side of the shell, triangular plates evenly fixedly installed on the inner side of the screening plate, and a screening hole between every two triangular plates.
[0006] As a preferred technical solution of this utility model, bases are fixedly installed on both sides of the shell, and rectangular plates located on both sides of the shell are fixedly installed on the top of the bases. Movable grooves are opened on the inner side of the rectangular plates, and elastic blocks corresponding to the shell are movably installed inside the movable grooves. A telescopic spring is elastically installed at the bottom of the movable grooves, and the telescopic spring is located inside the elastic block.
[0007] As a preferred technical solution of this utility model, the movable groove is provided with limiting grooves on both sides, and the elastic block is fixedly installed with limiting blocks located inside the limiting grooves on both sides of the bottom.
[0008] As a preferred embodiment of this utility model, a first crushing plate is fixedly installed on the inner side of the shell, a second crushing plate is movably installed on the inner side of the shell, and rotating wheels are movably installed at both ends of the top of the second crushing plate.
[0009] As a preferred embodiment of this utility model, a platform is fixedly installed on the rear side of the housing, and a servo motor is fixedly installed on the top of the platform. The output end of the servo motor is connected to the rotating wheel via a transmission belt.
[0010] As a preferred embodiment of this utility model, a fixing block is fixedly installed on the outer side of the output end of the servo motor, and the fixing block is located on the outer side of the transmission belt.
[0011] As a preferred embodiment of this utility model, a conveyor belt is provided below the discharge port 2 on the lower part of the housing, and the other end of the conveyor belt extends to the upper part of the inlet.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model involves pouring the ore to be crushed into the feed inlet, then starting the servo motor to crush the ore. The fine ore particles are screened through the screening holes and triangular plates, while larger ore particles fall through the discharge port into the conveyor belt. The conveyor belt then transports the ore particles back to the feed inlet for secondary crushing. Compared with traditional crushers, this crusher with better grinding effect uses a screening plate to screen the ore and a conveyor belt to transport the ore particles back to the feed inlet for secondary crushing.
[0014] 2. This utility model uses the shell to compress the elastic block, causing the rotating wheel to deform and move into the interior of the movable groove, thereby compressing the telescopic spring. The telescopic spring releases its elastic potential energy, pushing the elastic block outward, thus causing the elastic block to compress and fix the outer wall of the shell. Compared with traditional crushers, this crusher with good grinding effect effectively alleviates vibration by compressing and fixing the outer wall of the shell with the elastic block.

[0021] 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.
[0022] like Figures 1 to 5 As shown, this utility model provides a crusher with good grinding effect, including a shell 1, a feed inlet 2 on the top of the shell 1, two baffles 3 fixedly installed at the bottom of the shell 1, a discharge port 4 between the baffles 3 and the inner side of the shell 1, a discharge port 5 between the inner sides of the two baffles 3, a screening plate 6 fixedly installed above the discharge port 4 between the baffles 3 and the inner side of the shell 1, triangular plates 16 evenly fixedly installed on the inner side of the screening plate 6, and a screening hole 15 between every two triangular plates 16.
[0023] The ore to be crushed is poured into the feed inlet 2, and then the servo motor 12 is started. The servo motor 12 drives the rotating wheel 10 to rotate through the transmission belt 13. The rotating wheel 10 drives the second crushing plate 9 to move back and forth, thereby crushing the ore between the first crushing plate 8 and the second crushing plate 9. The crushed ore particles fall above the screening plate 6 and are screened through the screening holes 15 and the triangular plate 16. The larger ore particles fall into the conveyor belt 7 through the discharge port 25. The conveyor belt 7 transports the ore particles to the feed inlet 2 for secondary crushing.
[0024] The ore to be crushed is poured into the feed inlet 2, and then the servo motor 12 is started to crush the ore. The fine ore particles are screened through the screening holes 15 and the triangular plate 16, while the larger ore particles fall into the conveyor belt 7 through the discharge outlet 2 5. The conveyor belt 7 transports the ore particles to the feed inlet 2 for secondary crushing. Compared with traditional crushers, this crusher with better grinding effect screens the ore through the screening plate 6 and transports the ore particles to the feed inlet 2 through the conveyor belt 7 for secondary crushing.
[0025] The housing 1 has bases 17 fixedly installed on both sides, and rectangular plates 18 located on both sides of the housing 1 are fixedly installed on the top of the bases 17. The rectangular plates 18 have movable grooves 19 on their inner sides. Elastic blocks 20 corresponding to the housing 1 are movably installed inside the movable grooves 19. A telescopic spring 23 is elastically installed at the bottom of the movable grooves 19. The telescopic spring 23 is located inside the elastic block 20.
[0026] When the rotating wheel 10 is in operation, the vibration it generates causes the housing 1 to shake slightly, which in turn causes the housing 1 to press against the elastic block 20. This causes the rotating wheel 10 to deform and move into the movable groove 19, thereby pressing against the telescopic spring 23. The telescopic spring 23 then deforms and releases its elastic potential energy, pushing the elastic block 20 outward. This causes the elastic block 20 to press against and fix the outer wall of the housing 1, effectively mitigating the vibration.
[0027] The shell 1 compresses the elastic block 20, causing the rotating wheel 10 to deform and move into the movable groove 19, thereby compressing the telescopic spring 23. The telescopic spring 23 releases its elastic potential energy, pushing the elastic block 20 outward, thus pressing and fixing the elastic block 20 against the outer wall of the shell 1. Compared with traditional crushers, this crusher with better grinding effect effectively alleviates vibration by pressing and fixing the outer wall of the shell 1 with the elastic block 20.
[0028] Among them, the movable groove 19 has limit grooves 21 on both sides, and the elastic block 20 has limit blocks 22 fixedly installed on both sides of the bottom of the limit grooves 21.
[0029] The movement of the elastic block 20 inside the movable groove 19 causes the limiting block 22 to move inside the limiting groove 21, thereby limiting the elastic block 20.
[0030] Among them, a first crushing plate 8 is fixedly installed on the inner side of the shell 1, a second crushing plate 9 is movably installed on the inner side of the shell 1, and a rotating wheel 10 is movably installed at both ends of the top of the second crushing plate 9.
[0031] The rotor 10 drives the second crushing plate 9 to move back and forth, and the second crushing plate 9 crushes the ore through the gap at the bottom of the first crushing plate 8.
[0032] The housing 1 has a platform 11 fixedly installed on the rear side, and a servo motor 12 is fixedly installed on the top of the platform 11. The output end of the servo motor 12 is connected to the rotating wheel 10 through a transmission belt 13.
[0033] Start the servo motor 12, which drives the wheel 10 to rotate via the transmission belt 13. The wheel 10 drives the second crushing plate 9 to move back and forth, thereby crushing the ore between the first crushing plate 8 and the second crushing plate 9.
[0034] A fixing block 14 is fixedly installed on the outer side of the output end of the servo motor 12, and the fixing block 14 is located on the outer side of the transmission belt 13.
[0035] By installing the fixing block 14 on the outside of the output end of the servo motor 12, the fixing block 14 plays a limiting role on the transmission belt 13, preventing the transmission belt 13 from detaching from the servo motor 12.
[0036] The housing 1 has a conveyor belt 7 located below the discharge port 2 5, and the other end of the conveyor belt 7 extends above the inlet 2.
[0037] Fine ore particles are screened through screening holes 15 and triangular plates 16, while larger ore particles fall into the inside of conveyor belt 7 through discharge port 2 5. The conveyor belt 7 then transports the ore particles to the inside of feed port 2 for secondary crushing.
[0038] Working principle and usage process of this utility model:
[0039] The ore to be crushed is poured into the feed inlet 2, and then the servo motor 12 is started. The servo motor 12 drives the rotating wheel 10 to rotate through the transmission belt 13. The rotating wheel 10 drives the second crushing plate 9 to move back and forth, thereby crushing the ore between the first crushing plate 8 and the second crushing plate 9. The crushed ore particles fall above the screening plate 6 and are screened through the screening holes 15 and the triangular plate 16. The larger ore particles fall into the conveyor belt 7 through the discharge port 25. The conveyor belt 7 transports the ore particles to the feed inlet 2 for secondary crushing.
[0040] When the rotating wheel 10 is in operation, the vibration it generates causes the housing 1 to shake slightly, which in turn causes the housing 1 to press against the elastic block 20. This causes the rotating wheel 10 to deform and move into the movable groove 19, thereby pressing against the telescopic spring 23. The telescopic spring 23 then deforms and releases its elastic potential energy, pushing the elastic block 20 outward. This causes the elastic block 20 to press against and fix the outer wall of the housing 1, effectively mitigating the vibration.
