Abstract
The bottom of the aggregate storage bin is provided with a big discharging outlet and a small discharging outlet, each discharging outlet is respectively provided with a discharging gate which can be opened and closed, each discharging gate is connected with own rotating shaft which is driven by own cylinder. The automatic control system of the device sends out the discharging instruction to simultaneously open the two discharging gates to supply the material to the weighing storehouse, when the material supply reaches a certain value, the discharging outlet of the big discharging gate is closed, at the same time, the small discharging outlet still supplies with the small amount, until to the setting value, to close the discharging gate of the small discharging outlet to stop supplying. The utility model can greatly reduces the over weighing value, and can not influence the supplying time and the work efficiency, and can ensure the accuracy and the stability of the aggregate weighing.
Description
Technical field
The utility model relates to the discharge door mechanism of asphalt mixing plant hot aggregate storage bin.
Background technology
In asphalt mixing plant, the hot aggregate after the screening is stored in the aggregate bin, at the bottom of the storehouse of aggregate bin Dump gate is set, no matter present import equipment or home equipment, its Dump gate is the simple gate formula.The discharge process of aggregate bin is as follows: sends the instruction manipulating cylinder by the automatic control system of equipment, opens Dump gate at the bottom of the storehouse, and to the discharging of weighing storehouse, when reaching the setting weight value, the Weighing module output information in weighing storehouse, Dump gate is closed in the control system instruction.Because aggregate is successively to fall, therefore, reach and set the weighing value information and instruct when closing Dump gate when control system obtains aggregate in the weighing storehouse, this moment is some aggregate between Dump gate bottom and material top, weighing storehouse, also do not count in the weighing of Weighing module, be called super weighing.The super weighing of this part has influenced weighing accuracy, and is difficult to control, causes weighing error greater than setting, has directly influenced the grating quality of bituminous concrete, has reduced the quality and the service life of high grade pavement.If weighing error will be controlled at setting (be not more than weighing value ± 3%), the essential feeding speed that reduces, this can cause weighing time lengthening, cycle period to increase again, has reduced productivity ratio.
Summary of the invention
The purpose of this utility model provides a kind of discharge door mechanism of aggregate bin, both can improve the weighing accuracy of aggregate by this device, does not influence cycle period and productivity ratio again.
For achieving the above object, the discharge door mechanism of the aggregate bin that the utility model provides adopts following technical scheme: the bottom of aggregate bin is provided with two discharge ports of size, each discharge port is respectively arranged with Dump gate to be opened/closed, each Dump gate is connected in separately the rotating shaft, and rotating shaft is respectively by separately air cylinder driven.
The operation principle of this device is as follows: the automatic control system of equipment is sent discharging instruction manipulating cylinder, two Dump gate are opened simultaneously to weighing storehouse feed, when feed reaches certain value, the Dump gate of big discharge port is closed, this moment, little discharge port was still with little supply feed, until arriving setting value, the Weighing module output information in weighing storehouse, control system instruct the Dump gate of closing little discharge port to stop feed.Adopt this device, not only can reduce super weighing value, and do not influence feed time and productivity ratio, can also reduce to produce weighing error simultaneously, guaranteed the degree of accuracy and the stability of aggregate weighing owing to the impact of feed blanking.The actual use shows that the aggregate weighing precision improves 1 times, and precision is by original ± 3%, bring up to ± 1～1.5%.

Fig. 1 is the front view of the discharge door mechanism of aggregate bin.
Fig. 2 is the cutaway view along A-A direction among Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model provides the discharge door mechanism of the aggregate bin 1 on the asphalt mixing plant.Two discharge ports 2,3 of size are set in the bottom of aggregate bin 1, each discharge port is respectively arranged with arc Dump gate 4,5 to be opened/closed, Dump gate 4,5 is connected in separately the rotating shaft 6,7, one end of rotating shaft 6,7 is connected with rocking arm 8,9 respectively, drive rotating shafts 6,7 activities by separately cylinder by rocking arm 8,9, thereby handle the switching of Dump gate 4,5.
The duty of this device is by automatic control system and the program setting and the control of equipment, its operation principle is as follows: the automatic control system of equipment is sent discharging instruction manipulating cylinder, two Dump gate 4,5 are opened simultaneously to weighing storehouse feed, when being fed to certain value, the Dump gate of big discharge port 2 closes 4, and this moment, little discharge port 3 was still with little supply feed, until arriving setting value, the Weighing module output information in weighing storehouse, the Dump gate that 5 little discharge ports are closed in the control system instruction stops feed.
