Abstract
Description
Technical Field
[0001] The utility model relates to the field of round balers, in particular to a feeding mechanism of a double-roller round baler. Background Art
[0002] The working mode of the round baler is that power is transmitted to the round baler gearbox, and the round baler gearbox drives the sprocket through the chain drive to rotate the rollers in the frame assembly and the rear cover assembly. The sprocket drive of the round baler drives the rotation of the grass pusher and the auger, and the grass enters the mechanism through the feeding mechanism. The existing feeding mechanism is generally composed of a feeding base plate, a feeding base plate opening and closing cylinder, a base plate hanger, a feeding roller and other components. This type of feeding mechanism adopts a single-roller structure feeding method. The feeding inlet of this structure is small. When the round baler picks up a lot of materials with a high density, blockage is inevitable. When the feeding material is blocked, it is necessary to stop the machine and start the feeding base plate opening and closing cylinder to open the feeding base plate to spit out the blocked material, and then start the feeding base plate opening and closing cylinder again to reset and continue the operation. When the picked-up materials are large and dense, the above situation will occur frequently, thereby reducing the operating efficiency of the round baler. Utility Model Content
