Full terrain profiling device of harvester

Abstract

The invention provides a full terrain profiling device of a harvester and relates to the technical field of agricultural machinery. Suspension devices are separately arranged at the two sides of a header (6), each suspension device comprises a sliding sleeve (9), a suspending guide bar (10) and a suspension spring (12), the sliding sleeves (9) are fixed to side faces of the header (6), the suspending guide bars (10) penetrate into the sliding sleeves (9), lower ends of the suspending guide bars (10) are connected with fixed knife parts (8) of a cutter knife (5), upper ends of the suspension springs (12) are connected to the side faces of the header (6), lower ends of the suspension springs (12) are connected to the fixed knife parts (8) of a cutter knife (5), the suspending guide bar (10)at one side is fixedly connected with a shaft bracket (11), a rocking lever transmission shaft (3) is arranged at one side of the header (6) and is rotatably connected with the shaft bracket (11) through a bearing (14), and a rocking lever (4) is connected onto the rocking lever transmission shaft (3) at the outer side of the bearing (14)through a hinge part. The full terrain profiling device hasthe advantages that the structural design is reasonable, and the profiling of the cutter knife is more flexible.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester all-terrain profiling device for harvesters. Background technique [0002] Patent No. 00107270.6 discloses a single-ridge profiling device, which uses a swing ring and a rocker shaft with splines to connect with the cutter to drive the cutter to achieve shearing motion. The front end of the rocker shaft is fixed on the On the bearing seat connected with the knife beam, and hang on the side of the harvesting platform through the guide post, the guide post is equipped with a compression spring to cooperate with the cutting knife to realize the profiling function. When the profiling structure provided by this patent is actually used, due to the rigid connection between the cutter and the suspension device, when the harvester rides on the ridge for multi-ridge operations, the cutter will follow the topography of the higher side of the ridge. Affect the har...

Problems solved by technology

When the profiling structure provided by this patent is actually used, due to the rigid connection between the cutter and the suspension device, when the harvester rides on the ridge for multi-ridge operations, the cutter will follow the topography of the higher side of the ridge. Affect the harvesting effect of other ridges; the spring is used in a compressed state, the cutting knife is not flexible enough to copy, and the movement produces greater resistance, which also increases the energy consumption of mechanical equipment; in order to eliminate the axial displacement Adverse effect, the rocker shaft connected to the transmission shaft is splined, which has a large running noise, and the splined connection is easy to damage
