The specific embodiment
As Fig. 1-shown in Figure 4, in the material transferring system for spreading machine of the embodiment of the invention, a plurality of feeding tube bodies 1 vertically are installed in the anterior hopper of paver side by side and the rear portion paves between the parts, and the open-top of the leading portion of feeding tube body constitutes charging aperture 11, and the feeding tube rear end is provided with discharging opening 12; The leading portion of the feeding shaft 13 in the feeding tube body is provided with many group stirring vanes 14, stirring vane has certain propelling angle, therefore material can be pushed to back segment when material is stirred, the back segment of feeding shaft is provided with defeated material spiral 15, can be with mass transport to discharging opening 12.
As Fig. 1, shown in Figure 4, the top of feeding tube body 1 back segment is provided with a heater 2.Heater comprises a combustion chamber 21, at the top of combustion chamber burner nozzle 22 is installed, and the bottom of combustion chamber is provided with the heat-conducting plate 23 that a far infrared Heat Conduction Material is made, and can the material in the feeding tube body be heated.
As shown in Figure 5, heater also includes gas pipeline 24 that is connected with burner nozzle 22 and the combustion control system that combustion process is controlled, described combustion control system includes a microcomputer control device 25, computer control device obtains the combustion chamber temperature information by the temperature pick up 26 that is installed in the combustion chamber, computer control device obtains flame combustion state information by the probe 20 that is arranged on the burner nozzle place, computer control device is by ignition transformer 27 control burner igniting, computer control device leads to the pressure switch 28 that is connected on the gas pipeline and obtains pipeline pressure information, and computer control device is also by being connected the break-make of two main valves, the 29 control gas pipelines on the gas pipeline.
Combustion control system can be realized processes such as automatic igniting, auto extinguishing protection and the automatic control of temperature.Concrete control principle is as follows:
Automatic IGNITION CONTROL principle: at first open the steel cylinder gate valve, combustion gas enters gas pipeline 24, regulate pressure regulator valve, gaseous-pressure is met the demands, pressure switch 28 is opened, make computer control device 25 obtain signal, instruction unpack main valve 29,27 high-tension ignitions of instruction ignition transformer, probe 20 detects flame after several seconds, and signal passed to computer control device, light a fire successfully.If probe in detecting is less than flame, computer control device can not get signal, and instruction is closed main valve and reported to the police loss of ignition.
The temperature Automatic Control Theory: temperature pick up 26 detects actual temperature, and gives computer control device 25 with temperature signal, and when temperature was higher than target temperature, main valve 29 was closed in instruction; When temperature was lower than target temperature, automatic ignition procedure was restarted in control.
The blowout protection principle: be contained near the probe 20 of burner nozzle flame detection all the time, when combustion failure causes fray-out of flame, probe will send signal to computer control device 25, and main valve station 29 is closed in the computer control device instruction, reports to the police simultaneously.When the design of two main valves had guaranteed a main valve fault, system also can the safety cut-off combustion gas.
