<p>The granular fertilizer distributor has two spreader grids which are reciprocated, connected by connecting rods to swinging arms which can be adjusted through an angle of 90 deg. This movement is controlled by two sliders guided by a crank forming part of a control device. Each slider controls at least one transmission cylinder which remains in contact with the associated pistons. The cylinders and pistons are connected by lines to the cylinders which have their pistons connected to the swinging arms. The guide channels for the piston rods discharge into an oil bath in which are also mounted the controllers for the slider cranks. The cylinders are connected by lines to the oil reservoir which include pressure and check valves.</p> |
