METHOD AND DEVICE OF CONTROL FOR TRANSPLANTING QUANTITY OF SEEDLING FOR RICE TRANSPLANTER

摘要

PROBLEM TO BE SOLVED: To provide a rice transplanter controlling quantity of transplanted seedlings by providing a detecting function for remaining the seedlings, a detecting function for transplanted seedlings and a detecting function for consumption of the seedlings on the transplanter. SOLUTION: The transplanter increases or decreases feeding quantity of the seedlings on the seedling stand to a seedling take up port according to the detected remaining quantity of the seedlings by installing a detecting function to the seedling stand for the remaining quantity of seedling mats. The transplanter controls the quantity of the transplanting seedlings by detecting seedlings transplanted to a paddy field by electric signals and calculating traveling speed of the transplanter and intervals of transplanted stubs from intervals and time differences of the signals. The quantity of the seedling to be transplanted is controlled by detecting the seedlings transplanted to the paddy field by the function of detecting the quantity of the seedlings transplanted to the paddy field, and calculating and displaying the transplanted area, quantity of seedlings used in the transplanting and intervals of the transplanted stubs. The feeding quantity of the seedlings fed to the seedlings take out port from the seedling stand set to transplant the predetermined area with a predetermined number of the seedling mats or the quantity of the seedlings taken out by the seedling transplanting machine is controlled by installing the function detecting the quantity of the used seedlings and detecting the quantity of the transplanted seedlings to the paddy field and calculating the transplanted area and used seedlings.
