る。 One second after the drop position detector 11 is turned on, the pre-drop total weight WTi (TON) of the grab bucket 5, which has not yet been opened, is read into the calculator 21 from the output signal of the load cell 19. After 1.5 seconds or more have elapsed since the drop position detector 11 was turned on, the grab bucket 5 is opened and the drop is performed. The end of the drop is detected when the load of the grab bucket 5 decreases below the drop end set load (tare load),
At this time, the number of drops is read into the computing unit 2 position. Also, one second after this time, the weight at the end of dropping, WEi (TON), which is the tare load of the load cell 5 at that time, is calculated.
is read into the arithmetic unit 21. Based on the above data, "lifted soil volume" is calculated by "lifted soil weight" and "unit volume weight".
(preset), and the number of drops is determined by the number of times "start excavation" → "end drop". This kind of work is performed for each dumping, and the total amount of soil lifted Q (m 3 ) is calculated using the following formula.

できる利点がある。(Effect of the invention) As explained above, in the soil lifting amount measuring and recording device of the grab bucket type dredger according to the invention, the lifting weight is calculated by the calculator from the difference between the weight signals before and after dropping the grab bucket dredger using a load cell. Then, by dividing this by the unit volume weight, the amount of soil lifted per time is determined, and by adding up the amount of soil lifted each time, the total amount of soil lifted is calculated, so the total amount of soil lifted can be automatically calculated. It can be performed. Moreover, the obtained data can be automatically recorded with a recorder. Therefore, according to the present invention, it is possible to accurately measure and record the amount of soil lifted without much effort. Furthermore, if the weight of the grab bucket is measured before and after dropping after the dropping command is issued from the dropping position detection switch, there is an advantage that the weight can be accurately measured when dropping.
