By arranging a lower cone sleeve at the lower part of the moving cone of the gyratory crusher and arranging a T-shaped extrusion block with a long service life on the outer side of the lower cone sleeve, the utility model can effectively ensure the service life of the moving cone, and it is more convenient to maintain the moving cone, and there is no need to replace the entire cone, which greatly saves resources and has high economic efficiency.

[0004] When the above-mentioned dynamic cone is in use, the T-shaped extrusion block crushes materials such as iron ore, and the T-shaped extrusion block contacts the material, and the T-shaped extrusion block is subjected to force, which makes the T-shaped slot easily deformed by the force, thereby making it difficult to remove the subsequent T-shaped extrusion block from the T-shaped slot, and after removing it, it is difficult to install a new T-shaped extrusion block in the deformed T-shaped slot. For this purpose, a hydraulic gyratory crusher is proposed. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 - Figure 7As shown, the utility model provides a technical solution: a hydraulic gyratory crusher, comprising a frame 1, a power device is installed on the inner wall of the frame 1, a transmission shaft 5 is installed on the output end of the power device, a top cone assembly 2 is installed on the top of the transmission shaft 5, a moving cone assembly 3 is installed and connected to the transmission shaft 5, and an anti-deposit assembly 4 is installed inside the frame 1.

[0026] The moving cone assembly 3 includes a fixed frame 301, which is installed on the transmission shaft 5. A crushing blade 302 is installed on the inner wall of the fixed frame 301. A limiting block 303 for fixing the crushing blade 302 is installed inside the fixed frame 301. A limiting component for fixing the limiting block 303 is installed at the bottom end of the fixed frame 301. The limiting component includes a limiting frame 304, which is fixedly installed at the bottom end of the fixed frame 301. A slider 305 is installed inside the limiting frame 304. A through hole is opened inside the slider 305. A screw 306 is installed on the limiting frame 304. One end of the screw 306 passes through the through hole and passes through the slider 305 to be threadedly connected with a nut 307.

[0027] The top cone assembly 2 includes a top cone frame 201, which is installed at the top of the transmission shaft 5. The top of the top cone frame 201 is fixedly connected with a protective cover 202. The top of the top cone frame 201 is installed with a limiting rod 203, which is fixed to the top cone frame 201 by bolts. A rectangular hole is opened at the top of the transmission shaft 5, and the outer wall of the limiting rod 203 is adapted to the inner wall of the rectangular hole.

[0028] The anti-accumulation component 4 includes a motor No. 1 401, which is fixedly mounted on the frame 1, a disc 402 is fixedly connected to the output end of the motor 401, a movable frame 403 is slidably connected to the frame 1, a tooth piece 404 is fixedly connected to the movable frame 403, and one side of the movable frame 403 is slidably connected to one side of the disc 402.

[0029] One side of the disc 402 is fixedly connected with a cylinder, one side of the movable frame 403 is provided with an arc hole, and one side of the disc 402 is movably connected with one side of the movable frame 403 through the cylinder and the arc hole.

[0030] The outside of the transmission shaft 5 is fixedly connected with a transmission member, and the inner wall of the fixing frame 301 is provided with a transmission groove, and the outer wall of the transmission member and the inner wall of the transmission groove are matched.

[0031] A square hole is formed at the bottom of the fixing frame 301 , and the bottom of the limiting block 303 passes through the bottom of the fixing frame 301 through the square hole and contacts the sliding block 305 .

[0032] The screw 306 and the nut 307 are threadedly connected, but only a portion of the screw 306 is provided with threads. The portion of the screw 306 that contacts the limiting frame 304 and the slider 305 is provided with threads. Therefore, when in use, the force on the screw 306 can be reduced to reduce damage to the threads on the screw 306. The bending of the screw 306 has a small effect on the threads on the screw 306, which makes it difficult to separate the screw 306 and the nut 307. At the same time, when the limiting block 303 applies force to the slider 305, the main force is the limiting frame 304.

[0033] At the same time, the limiting block 303 has an inclination, and the inclination can be used to improve the convenience of separation. When fixing the crushing blade 302, it is necessary to clamp and fix the crushing blade 302 in six directions in the space. The structure of the fixing frame 301 itself can realize the limitation of the crushing blade 302 in three directions, and the three directions are perpendicular to each other. The limitations in the other three directions are respectively limited by two limiting components and a top cone component 2. For a crushing blade 302, there are two limiting blocks 303 and corresponding limiting components in contact with it respectively. During installation, the fixing frame 301 can be fixed to the transmission shaft 5 by means of a threaded rod. At this time, the top cone component 2 is placed on the fixing frame 301, and the top of the top cone frame 201 and the fixing frame 301 are in contact, so that the blades are in contact. At this time, the protective cover 202 is opened, and the protective cover 202 and the top cone frame 201 are detachably connected. Because the protective cover 202 is in use , the iron ore will not be crushed, so the protective cover 202 will not be subjected to excessive force, and the detachable part between the protective cover 202 and the top cone frame 201 will not be damaged, which will lead to the situation that it cannot be disassembled, so that the limiting rod 203 contacts the inner wall of the rectangular hole, and the bolt and nut 307 fix the limiting rod 203, so that the position of the top cone frame 201 is fixed, and the top cone frame 201 limits the crushing blade 302 in one direction, and installs the limiting block 303 through the square hole, and then installs the slider 305, the screw 306 and the nut 307, and limits the movement of the limiting block 303 through the slider 305, the screw 306 and the nut 307, and limits the crushing blade 302 through the limiting block 303, and limits the crushing blade 302 in two directions through two limiting blocks 303 and corresponding limiting components, thereby limiting the crushing blade 302 in six directions.

[0034] At the same time, when replacing the crushing blade 302, the restriction of the bolt nut 307 on the limiting rod 203 is released, and the limiting rod 203 is moved so that the limiting rod 203 and the rectangular hole are separated. At this time, the top cone frame 201 can be taken out from the transmission shaft 5. At this time, the top of the crushing blade 302 is not restricted by the top cone frame 201. Due to the inclined design of the limiting block 303, the crushing blade 302 can be taken out from the top of the fixing frame 301 and reinstalled, and then the top cone assembly 2 is installed again to complete the fixation of the crushing blade 302. Through the arrangement of the top cone assembly 2 and the moving cone assembly 3, the crushing blade 302 is placed in the fixed frame 301, and the fixed frame 301 can limit the crushing blade 302 in three directions. Then, the crushing blade 302 is fixed in the remaining three directions through the two limiting assemblies and the top cone assembly 2, and the top cone assembly 2 and the limiting assembly are detachable. By disassembling the limiting assembly and the top cone assembly 2, the crushing blade 302 and the fixed frame 301 can be separated, thereby ensuring the convenience of replacing the crushing blade 302.

[0035] The output end of motor No. 1 401 rotates, causing the disc 402 and the cylinder to rotate, and the cylinder applies force to the movable frame 403 through the arc hole, causing the movable frame 403 to move. Since the disc 402 and the cylinder are in circular motion, the movable frame 403 and the tooth piece 404 will move back and forth. Through the back and forth movement of the tooth piece 404, the crusher is unblocked and the ore blockage is reduced. Through the setting of the anti-accumulation component 4, the output end of motor No. 1 401 rotates, and the rotation of the disc 402 causes the tooth piece 404 to move back and forth. When the tooth piece 404 moves upward, the ore accumulation can be reduced. When the tooth piece 404 moves downward, a downward force is applied to the accumulated ore, increasing the tendency of the ore to move downward, thereby improving the crushing effect of the crusher on the ore.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
