Abstract
Plunger type hay baler having a frame 1 forming an internal pressing channel 5 in which a pressing plunger 9 moves in a reciprocating movement, an intake orifice 6 through which hay loads into the pressing channel 5 and a loading chute 7 which connects to the pressing channel 5 at the orifice 6. A loader 35 which operates in synchronization with the alternating movement of the plunger 9, periodically introduces into the loading channel 7 basic loads and causes them to go from the loading chute 7 into the pressing channel 5. The loader 35 and pressing plunger 9 are respectively associated with a transmission system 32, 22, 25, 24, 27, 28, 30 for transforming a continuously circular movement of a driving crankshaft 12 of the pressing plunger 9 into an alternating circular movement of the driving pivot 28 of the loader 35.
Claims8
A plunger type hay baler comprising:
- a frame internally defining a pressing channel;
- an intake orifice in said pressing channel for introduction of hay;
- a loading chute connected to said pressing channel at said intake orifice;
- a pressure plunger reciprocatable in said pressure channel
- loader means for periodically introducing hay from said loading chute to said pressing channel;
- a transmission system for synchronously driving said pressing plunger and said loading means, and for driving said loading means along a closed path of movement, said transmission system including,
- (a) a driving crankshaft,
- (b) first and second driving pivots associated with said loader means, and
- (c) means for converting rotational movement of said driving crankshaft to reciprocating rotary movement of said loader means
- means for automatically adjusting a position of one of said first and second driving pivots as a function of a rotational position of said driving crankshaft, whereby a shape of said closed path changes as a function of said rotational position of said driving crankshaft.
