Title: Regulating reservoir
Inventor: NAKAI TAIRA
IPC: E03F1/00
Filed: 1982-03-18
Abstract: PURPOSE:To increase the amount of drainage in the early period of inflow by a method in which a small water tank having an overflow portion on its upper part is provided at the inlet and outlet of a regulating reservoir, the lower parts of both small tanks are connected with a water conveyance pipe and the lower part of the water tank on the outlet side is provided with a drain port. CONSTITUTION:When rains start to fall, great amounts of rain water flows through an inflow pipe 1 into the first regulating tank 2, and the rain water concurrently flows into a drain tank 4 through a drain port 22 and a water conveyance pipe 23 and is discharged to downstream from a discharge pipe 5. In this case, in the first regulating tank 2, the water level is raised and the amount of drainage passing through the water conveyance pipe 23 is increased, but when the amount of inflow water becomes too great to handle, the water flows from the overflow portion into the second regulating tank 3. The rain water is discharged through the drain tank 4 from the drain port 32, but during the period, the water level of the second regulating tank 2 is raised to regulate the amount of drainage to the river. By this, the amount of drainage through the water conveyance pipe 23 even in the early period of inflow can be increased.

Abstract: PURPOSE: To improve the short turn performance of a four wheel drive machine by providing a clutch in the front drive and bringing the clutch to off position by a command from a section foe detecting that the lifting mechanism of the working tool is in the lifting position thereby reducing the radius to turning.  
     CONSTITUTION: When turning while lifting the working tool 10 equipped with the power agricultural machine 9, a drive cut-switch for the front wheels is turned on while the control lever 17 is rotated to the lifting position of the working tool to raise the lift arm 15. Consequently, the working tool 10 is suspended above the ground while the detecting section 12 functions to change over a valve by a solenoid. Consequently the cylinder will contract to bring the clutch through a clutch arm 5 into off state thus to stop the rotation of a power taking shaft 3 for the front wheels. Since only the rear wheels 20 are driven, the agricultural machine 9 is turned with small radius through single turning operation of the power agricultural machine 9 to the left or right.
