Title: Foreign matter-removing device of rice transplanter
Inventor: WAKUTA TADAO
IPC: A01C5/06
Filed: 1988-09-20
Abstract: PURPOSE:To prevent the generation of a mud push by introducing a foreign matter-removing device composed of rotators and disposing an interval- controlling means where the interval of the rotators in the shaft core direction at the upper portion of the rotation passageway of the rotators is smaller than that of the rotators at the lower portion thereof. CONSTITUTION:An interval L1 between rotators 1 at the upper portion of the rotation passageway of the rotators 1 in the shaft core direction is shortened compared with that L2 at the lower portion by an interval-controlling means. A cam 1b and a spring 1c rubbedly contacting with the rotators 1 and controlling the rotators 1 to the posture of a reverse V shape on the front view are attached to a supporting shaft 17a. Gears 1d are formed on the opposing surfaces of two rotators 1, respectively, and the intermeshing of the gears 1d at the upper phase controls a deviation between the positions of the left and right rotators 1 in the rotation direction. Thereby, foreign matters located at positions approximately vertical in the rotation direction of the wheel 16 can be also pushed into the soil with a pair of the left and right rotators 1 without slipping off.

Abstract: PURPOSE:To perform the synchronization/comparison processes with no conflict in terms of the control of constitution by sending the synchronization request information to a computer of another system via a network and at the same time fetching the synchronization request information having made a round of the network via a computer of its own system when a synchronization request is produced. CONSTITUTION:When the synchronization and comparison requests are produced, these requests are registered into a transmission data intermediate file 33 via the synchronization and comparison request linkage subroutines 31 and 32. At the same time, a network data transmission program 34 is started. The program 34 takes the data out of a file 33 and sends it to a network. This transmitted data is received by a network data reception program 35 and registered into a reception data intermediate file 36. Then a synchronization/ comparison process program 37 is started. The program 37 takes the data out of the file 36 and decides the maintenance and the end of synchronization for a synchronization table, a comparison table, and a time-out table respectively based on the request data. Thus the synchronization/comparison processes are attained with no conflict.
