Abstract

1519307 Maintaining a harvester body upright INSTITUTUL DE CERCETARI SI PROIECTARI DE MASINI AGRICOLE 15 Sept 1975 37853/75 Heading AIF [Also in Division G3] A device for maintaining the body of a harvester-thresher upright is characterised by the fact that in order to achieve a continuous variation of the speed of the righting movement it uses a pendulum 6 which activates a flow controller B which controls an adjustable valve A the latter taking a part of the flow of a pump 1 proportional to the tilting angle of the body, the absorbed flow passing first through the valve A and then the controller B and the rest of the flow of the pump passing through an electrically activated distributor 2 to hydrostatic cylinders 4 which right the body. In the embodiment the pendulum 6 is fixed to a rotary slide 13 in the controller, Fig. 4, causing a back pressure at f in the adjustable valve Fig. 2 to move the slide 10 thereof and inhibit flow through the valve A. Also fixed to the coupling is a ferromagnetic core which when the pendulum is tilted one way increases the coupling between two coils (L1, L2) Fig. 6, (not shown) and a transistor (To) starts oscillating. The collector voltage is rectified and subsequently amplified and used to excite an electromagnet (3) which operates the distributor 2 to direct flow to the cylinders 4 to right the body and switch off the circuit. When the pendulum tilts the other way it operates an identical circuit actuating the cylinders in the opposite sense. A horn (22) and a light (23) in the control circuit, Fig. 5 (not shown) operate to warn if the maximum rate of the machine has been exceeded or if the circuit has a fault.
