Title: Boom actuation of an under-stem mulcher or under-stem clearer with an electric motor
Inventor: RECK RUDI DIPL ING
IPC: A01B39/26
Filed: 1993-08-09
Abstract: The booms of the under-stem mulchers or under-stem clearers available on the market have to be drawn inwards either mechanically (complicated) or hydraulically (not environmentally friendly) when there are young plants or when they move in reverse. This object is to be achieved by means of two electric motors. As result, the system becomes more cost-effective than the hydraulic system and environmentally friendly. Electric motors can draw the booms inwards and move them outwards via a rope drive, rack drive or friction-wheel drive. At the same time, the movement can take place manually via a switch or via a touch contact. The outermost and innermost position is determined by limit switches. In the touch-contact circuit shown in Figure 8, contacts are mounted in the touch-contact guide, Figure 7, and move the boom inwards or outwards as required. As long as the touch contact is pressed inwards by a vine stem, the boom moves inwards. As soon as the touch contact is free again, the boom moves outwards again. Under-stem mulchers and under-stem clearers are employed in viniculture and fruit-growing during environmentally friendly farming. <IMAGE>
