Abstract

The invention discloses charging automatic control system of boiling type pith-removing machinery. A current sensor is mounted on a motor of the boiling type pith-removing machinery; a material blanking baffle plate is arranged in a bagasse blanking hole of a bagasse conveyor belt before the bagasse enters the boiling type pith-removing machinery; the baffle plate is driven by an electric hydraulic pushing rod; a monitoring system is mounted above the bagasse blanking hole and a spiral blade of the boiling type pith-removing machinery; a PLC (programmable logic controller) is mounted in an operating room, and connected with the display screen; the current sensor is used for transmitting a current value signal of the boiling type pith-removing machinery to the PLC; after being processed by an inner order of the PLC controller, the signal is output to control a motor of the electric hydraulic pushing rod to operate, so that the electric hydraulic pushing rod is driven to work; the opening degree of the blanking baffle plate is regulated to control amount of the bagasse of the bagasse blanking hole, so that the normal dispersing and turning work of the pith-removing machinery to the bagasse is guaranteed; the monitoring system is mounted, so that the operation staff can know the conveying state of the bagasse and the workings tate of the boiling type pith-removing machinery.

Example Embodiment

[0024] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0025] After the sugarcane is squeezed, the bagasse (4) is transported to the bagasse conveyor belt (2), combed through the adjustment baffle (12), and at the same time, the bagasse conveyor belt monitor (3) transmits the field data to the PLC controller (1), The PLC controller (1) issues instructions to control the electro-hydraulic push rod motor (11) to drive the electro-hydraulic push rod (6) to move, and push the bagasse (4) into the bagasse blanking port (8) and enter the boiling type pitting machine (9 ) to remove pitting; a current sensor (14) is installed in the drive circuit of the pitting machine motor (7), and a boiling type pitting machine monitor (5) is installed above the spiral blade of the boiling type pitting machine (9), and the current The sensor (14) and the boiling-type pitting machine monitor (5) are connected to the PLC controller (1) by means of a serial communication bus; the PLC controller (1) communicates with the display touch screen (13), which is convenient for operators The whole system is monitored; the pith is transported to the boiler for combustion through the pith conveyor belt (10).
[0026] The working principle of the present invention is: a current sensor (14) is installed on the pitting machine motor (7), and a blanking baffle is provided at the bagasse blanking port (8) of the bagasse conveyor belt before the bagasse enters the boiling type pitting machine , the baffle is driven by an electro-hydraulic push rod (6), a monitoring system is installed above the bagasse discharge port (8) and the spiral blade of the boiling type pitting machine, a PLC controller (1) is installed in the operating room, and a touch screen is connected ( 13), the current sensor (14) transmits the current value signal of the pitting machine motor (7) to the PLC controller (1), and is processed by the internal command of the PLC controller (1), and the output signal controls the electrohydraulic push rod motor (11 ) to operate, drive the electro-hydraulic push rod (6) to work, and at the same time adjust the opening degree of the blanking baffle, so as to control the amount of bagasse (4) at the bagasse blanking port (8) and ensure that the boiling type pitting machine (9 ) to maintain the normal work of breaking up and throwing bagasse (4); the display touch screen (13) is connected with the monitoring system to install the monitoring system on the top of the bagasse blanking port and the spiral blade of the boiling type pitting machine, and give the operator Understand the conveyance of bagasse (4) and the working status of the boiling type pitting machine (9).
[0027] The above is only a preferred embodiment of the invention, and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the description of the invention and the contents of the accompanying drawings, or directly or indirectly used in other related technical fields, are the same as The theory is included in the patent protection scope of the present invention.
[0028] The applicant originally had 6 pitting machines. Before the 2013 cropping season, it mainly relied on manual control of the bagasse entering the pitting machine. Due to the long distance of the conveyor belt, the bagasse feeding was not very uniform, resulting in sometimes a lot of bagasse entering the pitting machine. , sometimes less, workers need to use a rake to clear it, and when there is a lot of bagasse, the motor load of the pitting machine is heavy, the current is instantly large, and the machine makes a lot of noise. The technician checks and finds that the motor is overheated. Although management has been strengthened, there are still some problems The motors of the two pitting machines were burnt out. After redesigning and installing the automatic feeding control system of the pitting machine of the present invention, the PLC controller (1) internally commands the output signal to control the electrohydraulic push rod motor (11). operation, drive the electro-hydraulic push rod (6) to work, and at the same time adjust the opening degree of the blanking baffle, so as to control the amount of bagasse blanking port (8) and bagasse (4) to ensure that the boiling type pitting machine (9) The normal work of breaking up and throwing bagasse (4) was maintained, 4 operators were reduced in the whole workshop, the pitting machine was working normally, and none of the motors burned out in the 2014 cropping season.
