Agricultural baling press overload safety device - has springs and adjustable stops allowing tines to slip when load is excessive

摘要

The agricultural baling press for hay, straw, etc. incorporates an overload prevention system. On a reciprocating arm (1) which carries rollers (4) which travel inside a guide slot (5) are suspended tines (7) which follow an elliptical path. The arm is attached to a chain drive (2) which causes this movement. The region of this arm between the lines incorporates friction layers (6) both sides. Behind the rear tine is a further tine (15) and between them is a spring (10) mounted around the carrier arm (1). This forms an overload protection, and instead of friction layers, rollers may be used. At the outer end of the carrier arm is a resilient buffer for the leading line. An adjustable stop (11) is include one end of the spring.
