較器１に送られ゛（設定された掻取り量と比較される。When unloading, the scraping amount and unloading amount are set. Thus, the speed signal V is based on the set scraping purpose. is outputted from the moving speed regulator 2 and sent to the moving speed controlling device 3, and the batts 1 to 1 conveyor scraping section moves at a predetermined speed according to the command signal 13 from the controlling device 3 and scrapes the waste material 1.
Rige is held. In addition, the scraping amount detector 4 detects the
In the case of the phototube method described above, the scraping suspension is detected as the ratio of the time it takes for the bucket to move one pitch to the light shielding time, and the signal is sent to the processing unit 5, where it is The actual scraping amount is calculated, and the signal is sent to the comparator 1 (compared with the set scraping amount).

The set unloaded M is compared with the average flow rate output as 0, and if the set unloaded amount and the extracted average flow rate are not equal, a deviation signal is sent to the comparator 9J. H1
! The coefficient corresponding to the deviation is output from the unloading M adjuster 10 and sent to the scraping m correction device 6, where the calculated value sent from the C arithmetic processing device 5 is output. The amount of scraping is corrected by applying the amount of scraping m, and the corrected amount of scraping is output to the comparator 1. If there is a difference between the corrected scraping boat and the set scraping amount, the deviation is output from the comparator 1, and the -C control is performed in the same manner as described above.

優れた効果を奏し得る。According to the scraping amount control method of a continuous unloader of the present invention, the average flow rate is excluded from the stacked volume at regular intervals, the average flow rate and the set unloading amount are compared, and scraping is performed according to the difference. Since the correction is made by 1J, it is not affected by instantaneous load fluctuations, and it directly detects scraping and lifting.
- The moving speed of the conveyor scraping section is controlled by 011/C, which is not affected by the detection delay caused by the scale on bell 1 and achieves stable control, which produces various excellent effects on the pipe. obtain.
