Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of impact crusher, and relates to a wear -resistant plate hammer. BACKGROUND

[0002] The plate hammer is a key component in the impact crusher, which is usually installed on the surface of the rotor. The plate hammer is driven by the high-speed rotating rotor to rotate at high speed and repeatedly hit the materials entering the crushing cavity, thereby completing the crushing operation.

[0003] During the high-speed rotation of the plate hammer, the materials will collide violently, which will easily cause the temperature of the surface of the plate hammer to rise. At this time, the high temperature will accelerate the wear of the plate hammer, shorten the service life of the plate hammer, and reduce the crushing efficiency of the equipment. In order to reduce the impact of high temperature on the plate hammer, a cooling system such as a liquid cooling or air cooling system is used to cool the plate hammer. However, during the actual operation of the plate hammer, when the materials are dense, large in particle size or high in humidity, an obstacle will be formed in the contact area between the materials and the plate hammer, which will make the air flow not easy to directly contact the surface of the plate hammer, thereby reducing the cooling effect of the plate hammer. Although the liquid cooling system can more quickly and effectively reduce the temperature of the plate hammer, the plate hammer and the rotor will continuously contact the materials and be impacted by the materials during operation, which will easily cause the liquid cooling system to leak.

Mounting shafts 4 are installed at the center ends of both ends of the outer wall of the rotor 1, used to connect and install the rotor 1 to an impact crusher. A mounting bearing 5 is provided at the end of the mounting shaft 4 near the rotor 1, used to reduce the friction generated during rotation between the mounting shaft 4 and the impact crusher, allowing the rotor 1 to rotate smoothly. A pulley set 6 is provided at the end of one set of mounting shafts 4 away from the rotor 1. A drive motor 7 is connected to one end of the pulley set 6, used to provide power for the rotation of the rotor 1. The model number of the pulley set 6 is HC-SFS702. Multiple sets of crushing teeth 3 are installed around the outer wall of the rotor 1, used to further crush or grind materials when the rotor 1 rotates.

[0027] The rotating assembly is mounted on rotor 1 and is used in conjunction with rotor 1.

[0028] Example 2

[0029] like Figures 1-5As shown, the wheel assembly includes a first transmission rod 10 and gear set 11, the first transmission rod 10 is rotatably connected through a set of mounting shaft bracket 4 inside the second rotating rod 30, the first transmission rod 10 is provided with a gear set 11 at one end, the gear set 11 is connected with a first adjusting motor 12 at one end, the model is HC-SFS702, the second rotating rod 30 is extended to the inside of the rotor 1 at one end and is connected with a first valve disc 13 at the middle end, a plurality of first adjusting grooves 14 are provided on the first valve disc 13 at equal intervals, a first sliding block 15 is slidably connected in the first adjusting groove 14, a plurality of first sliding blocks 15 are located at one end of the plurality of first adjusting grooves 14 away from the second rotating rod 30, a first connecting plate 16 is connected at one end of the first sliding block 15, and the first connecting plate 16 is connected with the first plate hammer 8 at one end.

[0030] As shown in Figures 1-5 , the wheel assembly also includes a second transmission rod 22, the second transmission rod 22 is rotatably connected through a set of mounting shaft bracket 4 away from the first transmission rod 10 inside the first rotating rod 17, the second transmission rod 22 is provided with a gear set 11 at one end, the gear set 11 is connected with a second adjusting motor 23 at one end, the model is HC-SFS702, the first rotating rod 17 is extended to the inside of the rotor 1 at one end and is connected with a second valve disc 18 at the middle end, a plurality of second adjusting grooves 19 are provided on the second valve disc 18 at equal intervals, a second sliding block 20 is slidably connected in the second adjusting groove 19, a plurality of second sliding blocks 20 are located at one end of the plurality of second adjusting grooves 19 away from the first rotating rod 17, a second connecting plate 21 is connected at one end of the second sliding block 20, and the second connecting plate 21 is connected with the second plate hammer 9 at one end.

[0031] As shown in Figures 1-5 , a plurality of guide frames 24 opposite to the positions of the first plate hammer 8 and the second plate hammer 9 are fixedly connected around the inside of the rotor 1, a plurality of guide rods 25 penetrating through the inside of the guide frame 24 are fixedly connected at one end of the first plate hammer 8 and the second plate hammer 9, a limiting block 26 is fixedly connected at one end of the guide rod 25, the guide rod 25 can limit the moving track of the first plate hammer 8 and the second plate hammer 9 when they move, and provide certain supporting effect when they work.

[0032] During operation, the mounting bracket 4 is installed with the mounting bearing 5 and then mounted on the impact crusher. In use, the output of the drive motor 7, in conjunction with the pulley assembly 6, drives the mounting bracket 4 and rotor 1 to rotate inside the impact crusher. The first hammer 8, located outside the rotor 1, crushes the fed material. After a period of operation, the output of the first regulating motor 12 drives the gear set 11 to rotate the first transmission rod 10, which in turn rotates the second rotating rod 30 and the first valve disc 13. This causes the first slider 15 to slide inside the first regulating groove 14 to a position close to the second rotating rod 30. At this time, the first hammer 8, driven by the first connecting plate 16, moves through the sliding groove 2 into the rotor 1. Simultaneously, the second regulating motor... The output end drives the gear set 11 to rotate the second transmission rod 22, which in turn drives the first rotating rod 17 and the second valve disc 18 to rotate. This causes the second slider 20 to slide inside the second adjusting groove 19 to the end away from the first transmission rod 10. At this time, the second hammer 9, driven by the second connecting plate 21, extends out of the rotor 1 through the sliding groove 2. This allows multiple sets of first hammers 8, which are in a high-temperature state, to leave the working area, and allows multiple sets of second hammers 9 to enter the working area. This enables multiple sets of first hammers 8 and second hammers 9 to work alternately, allowing each set of first hammers 8 or second hammers 9 to have a certain cooling time, reducing the risk of overheating and damage, and reducing downtime caused by high temperature of first hammers 8 or second hammers 9, thereby improving the continuous operation capability of the equipment.

[0035] like Figures 1-5 As shown, multiple sets of exhaust holes 29 are equidistantly arranged around the inside of the first rotating rod 17 and the second rotating rod 30.

[0036] In working, the refrigerant gas is delivered to the inside of the first rotating rod 17 and the second rotating rod 30 through the gas delivery pipe 28, and then is discharged to the inside of the rotor 1 through the gas discharge hole 29, so as to rapidly cool the first plate hammer 8 or the second plate hammer 9 staying in the inside of the rotor 1, and the refrigerant gas can continuously be discharged through the connecting gap between the chute 2 and the first plate hammer 8 or the second plate hammer 9, so as to cool the contact area of the two with the chute 2, to improve the comprehensiveness of the cooling, and when the refrigerant gas is discharged through the connecting gap, the refrigerant gas is located in the inside of the impact crusher, so as to reduce the stability of the inside of the impact crusher in operation, and cool the first plate hammer 8 or the second plate hammer 9 in the working state, to reduce the cycle of the two.
