Technical Field

[0002] Hammer crushers are equipment that crush materials by impact. They are suitable for crushing medium-hard materials such as limestone, slag, coke, and coal in industries such as cement, chemical, power, and metallurgy. When crushing materials, hammer crushers often produce flying debris, so gates need to be installed to improve safety and control the material input.

[0003] The existing hammer crusher gate is moved by manually operating a handle or drive assembly to control the gate when feeding is required;

Furthermore, if operators forget to close the gate after opening it, crushed material fragments may fly out, posing a safety hazard. Therefore, we propose an intelligent switching device for hammer crusher gates. Utility Model Content

The device is characterized in that: a single-chip microcomputer 15 is disposed on the outer side of the base 1, the input end of the single-chip microcomputer 15 is electrically connected to the output end of an external power supply; a drive shaft 6 is rotatably connected inside the crushing chamber 3, a hammer disc 12 is fixedly connected to the outer surface of the drive shaft 6, uniformly distributed fixing rods 13 are fixedly connected inside the hammer disc 12, and uniformly distributed hammer heads 14 are rotatably connected to the outer surface of each fixing rod 13; uniformly distributed impact liner plates 11 are fixedly connected to the upper surface of the crushing chamber 3; a pulley 7 is fixedly connected to the front end of the drive shaft 6; a drive shaft 8 is rotatably connected to the left side of the upper surface of the base 1, and a feed inlet 4 is fixedly connected to the front end of the drive shaft 8. Belt pulley 2 9 is connected to belt pulley 1 7 via belt drive. Motor 2 is fixedly connected to the left side of the upper surface of base 1. The front end of the output shaft of motor 2 is fixedly connected to the rear end of transmission shaft 2 8. The input end of motor 2 is electrically connected to the output end of microcontroller 15. When microcontroller 15 is operated, motor 2 is started. The output shaft of motor 2 rotates, which drives transmission shaft 2 8 to rotate, causing belt pulley 2 9 to rotate, which drives belt pulley 1 7 to rotate, which drives transmission shaft 1 6 to rotate, which drives hammer disc 12 to rotate, causing hammer head 14 to rotate around transmission shaft 1 6, thereby crushing the material. During crushing, the material impacts the impact liner 11, thereby improving the crushing effect. Screen plate 10 is fixedly connected to the lower side of the inside of crushing chamber 3. The upper surface of screen plate 10 has evenly distributed screen holes. The crushed material falls out of crushing chamber through the screen holes on screen plate 10. It also includes gate switch mechanism 5.

[0024] Gate switching mechanism 5: It includes a rotating shaft 52, an electric push rod 53, a connecting rod 54, a gear 55, a gear 56, and a rotating shaft 57. The rotating shaft 57 is rotatably connected to the rear surface of the crushing chamber 3. The gear 56 is fixedly connected to the front end of the rotating shaft 57. The connecting rod 54 is fixedly connected to the outer surface of the rotating shaft 57. The electric push rod 53 is rotatably connected to the rear surface of the crushing chamber 3.

The device 51 is fixedly connected to the inner upper surface of the feed inlet 4. The proximity sensor 51 is bidirectionally electrically connected to the microcontroller 15. When the material to be crushed is placed in the feed inlet 4, the proximity sensor 51 detects the material and sends a signal to the microcontroller 15. The microcontroller 15 controls the electric push rod 53 to run, causing the telescopic end of the electric push rod 53 to extend, driving the connecting rod 54 to rotate around the second rotating shaft 57, causing the second gear 56 to rotate, driving the first gear 55 to rotate, causing the first rotating shaft 52 to rotate, driving the gate 16 to rotate counterclockwise, allowing the material to enter the crushing chamber 3. When the material has entered, the proximity sensor 51 can no longer detect the material and sends a signal to the microcontroller 15. The microcontroller 15 controls the telescopic end of the electric push rod 53 to retract, causing the gate 16 to reset.

[0025] The working principle of the intelligent gate switch device for a hammer crusher provided by this utility model is as follows: When using this intelligent gate switch device, the material to be crushed is placed in the feed inlet 4. At this time, the proximity sensor 51 detects the material and sends a signal to the microcontroller 15. The microcontroller 15 controls the electric push rod 53 to run, causing the telescopic end of the electric push rod 53 to extend, driving the connecting rod 54 to rotate around the second rotating shaft 57, causing the second gear 56 to rotate, driving the first gear 55 to rotate, causing the first rotating shaft 52 to rotate, driving the gate 16 to rotate counterclockwise, allowing the material to enter the crushing chamber 3. The microcontroller 15 is then operated to start the motor 2, and the output of the motor 2... The rotation of the shaft drives the second transmission shaft 8 to rotate, which in turn drives the second pulley 9 to rotate, which in turn drives the first pulley 7 to rotate, which in turn drives the first transmission shaft 6 to rotate, which in turn drives the hammer disc 12 to rotate, causing the hammer head 14 to rotate around the first transmission shaft 6, thereby crushing the material. During crushing, the material impacts the impact liner 11, thereby improving the crushing effect. The crushed material falls out of the crushing chamber through the screen holes on the screen plate 10. Material that cannot pass through the screen holes will continue to be impacted by the hammer head 14 on the screen plate 10 until it is crushed. When all the material has entered, the proximity sensor 51 can no longer detect the material and transmits a signal to the microcontroller 15. The microcontroller 15 controls the extension end of the electric push rod 53 to retract, so that the gate 16 is reset.

[0026] It is worth noting that in the above embodiments, the motor 2 is YBZR200L-8, the proximity sensor 51 is NI20-CP40-VP4X2, the electric actuator 53 is JRZ06, and the microcontroller 15 is STC89C51. The microcontroller 15 controls the operation of the motor 2, the proximity sensor 51, and the electric actuator 53 using methods commonly used in the prior art.
