Detailed implementation manners

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the present invention provides an intelligent three - combination tire - type crushing and screening station, including:

[0030] The bottom frame 1, the support combination frame 2, the feeder 4, the impact crusher 5, the environmental protection screen 6, the main belt conveyor 7 for the discharge of the impact crusher, the feeding belt conveyor 8 for the environmental protection screen, the discharge belt conveyor 9 under the environmental protection screen, the return belt conveyor 10 for the material on the screen, the electric control system 12, the split upper frame 13, and the ultrasonic sensor 19;

[0031] The supporting assembly frame 2 is installed on the bottom frame 1, the feeder 4 and the impact crusher 5 are fixedly installed on the bottom frame 1, the impact crusher discharging main belt conveyor 7 is installed at the bottom of the impact crusher 5, the environmental protection screen upper belt conveyor 8 and the environmental protection screen lower discharging belt conveyor 9 are respectively installed on the top and bottom of the environmental protection screen 6, the feeder 4 is installed with a feed silo 3, and the ultrasonic sensor 19 is installed on the feed silo 3.

[0032] Through the above structure, the raw material is fed to the feed bin 3, fed to the feed port of the impact crusher through the feeder 4, and then enters the impact crusher 5 for crushing; when the material size is too large, and the material contains materials that are not easy to crush, such as steel bars, the material layer at the feed port of the impact crusher will be raised and blocked. In serious cases, the impact crusher 5 will be stuck and shut down, affecting production efficiency. Subsequent cleaning is time-consuming and laborious. Through the ultrasonic sensor 19 installed on the upper end of the feed bin 3, the ultrasonic sensor 19 will monitor the relationship between the material layer thickness on the feeder 4 and the warning line h0-is the maximum thickness allowed for the feeder 4 in real time; when the ultrasonic wave transmits the signal to the PLC frequency conversion controller that controls the feeder 4 through the material level control intelligent system, the frequency conversion controller sends a signal to change the frequency of the feeder motor. Reducing the frequency can reduce the feeding amount of the feeder 4 to prevent the feed port of the impact crusher from being blocked. Resuming the increased frequency can increase the feeding amount of the feeder 4, so that the impact crusher 5 can achieve the maximum crushing efficiency.

[0033] It should be noted that through the PLC-intelligent controller and intelligent remote monitoring of the electric control system 12, the key parameters in the electric control system 12, such as current, voltage, power, and feeding height, are monitored in real time on the display screen on the electric control cabinet, and the ultrasonic sensor 19 can capture the real-time status of each signal with high precision, providing accurate information for subsequent data collection and processing;

[0034] The automatic temperature measurement system signal is transmitted to the cloud platform through the internal communication network for further analysis and storage control system, which has fault monitoring function. Once a fault is detected, the control system will take prompt measures, intelligent fault display, and alarm buzzer will sound to prevent the fault from expanding and causing more serious consequences;

[0035] Based on the collected data, the smart chip control system intelligently controls the entire process system of the crushing station according to preset strategies and rules. Through Internet technology, users can remotely access and control the smart electric control cabinet, including real-time viewing of equipment status, remote control of equipment switches and parameter settings, and receiving fault diagnosis reports. This not only improves the safety, stability and reliability of the crushing station's working system, but also reduces manual intervention and management costs.

[0036] Specifically, a counterattack crusher 5 is provided with a counterattack crusher feed inlet. A transfer chute 11 is provided on the main discharge belt conveyor 7 of the counterattack crusher. A transfer chute 18 is provided on the environmental protection screen feeding belt conveyor 8. A post-screen chute 16 is provided on the environmental protection screen 6. A screen discharge bin 17 is provided at the bottom of the environmental protection screen 6.

[0037] Specifically, a bearing housing 22 is installed on the counterattack crusher 5. An automatic lubrication system 20 and a bearing temperature sensor 21 are installed on the bearing housing 22. An oil filling hole is provided on the bearing housing 22. The automatic lubrication system 20 is installed in the oil filling hole. The automatic lubrication system 20 includes a grease storage tank, a pressure pump, a flow sensor and a controller. It should be noted that the model of the bearing temperature sensor 21 is PT100. When the bearing temperature sensor 21 is placed in the measured environment, the platinum resistance element inside it will change the resistance value with the change of the environmental temperature. By measuring the resistance value of the platinum resistance element and using a specific mathematical formula, the temperature of the measured environment can be calculated, and then it is fed back to the screen of the electric control system 12 through a signal. When the bearing temperature value exceeds the set warning value, the electric control system 12 will send out an alarm signal to indicate that the bearing temperature is too high, and then prompt to stop the machine and carry out maintenance to prevent the bearing from being damaged by high temperature.

[0038] Working principle:

[0039] It can realize automatic monitoring of material jamming and blockage, automatically adjust the feeding amount, automatically monitor the bearing temperature, and automatically refuel at regular intervals and in fixed quantities; for the control and operation of this solution, the ultrasonic sensor 19 installed on the feeder 4 monitors the stacking height of the feeding bin 3 on the feeder 4, and judges whether the material layer height of the feeding bin 3 on the feeder 4 and the feeding port of the impact crusher exceeds the warning line. If the material layer height is lower than the warning line, through signal feedback to the feeder 4, the PLC controls the feeder 4 to increase the running speed and increase the feeding amount. If the material layer height is higher than the warning line, through signal feedback to the feeder, the PLC controls the feeder 4 to reduce the running speed and decrease the feeding amount. In this way, the feeding port of the impact crusher will not be blocked, and the impact crusher 5 can be kept at the maximum load for efficient production. The ultrasonic sensor 19 transmits the signal to the electric control system 12, thereby controlling the feeding speed of the feeder 4; the automatic lubrication system 20 on the bearing seat 22 of the impact crusher 5 can be monitored and adjusted in real time. The operator sets parameters such as the lubrication time interval and flow rate through the electric control system 12 and starts the device. The pressure pump starts to work, generating pressure to extrude the grease from the grease storage tank. At the same time, the controller adjusts the working state of the pressure pump according to the preset value to ensure that the grease is output at a constant flow rate; the grease is transported to the lubrication points through the pipeline system. The electric control system 12 continuously monitors the working state of the device and automatically adjusts the parameters as needed to ensure an ideal lubrication effect. By connecting a bearing temperature sensor 21 to the bearing seat 22, the temperature of the bearing can be uploaded to the electric control system 12. When the bearing temperature is relatively high, an alarm signal will be issued, indicating that the bearing temperature rise is too large and the machine needs to be stopped for inspection to avoid damage to the bearing due to excessive temperature.
