Vertical shaft rotary traction mechanism of forage harvesting and flattening machine

Abstract

The invention provides a vertical shaft rotation type drawing mechanism for a forage grass cutting flatting mill. The vertical shaft rotation type drawing mechanism comprises a first horizontal shaft protecting cover, a first horizontal shaft, a bevel gear, a power input box, a rotation box, a vertical shaft, a second horizontal shaft, a connecting plate, a limiting box, a connecting frame, a cylindrical roller and a supporting frame. A tractor transmits power to the first horizontal shaft, the first horizontal shaft transmits power to the vertical shaft, the vertical shaft transmits power to the second horizontal shaft, the second horizontal shaft transmits power to the forage grass cutting flatting mill, and power transmission is finished. When the tractor makes a turn, a power transmission system works normally, the power input box and the limiting box make a turn together with the tractor, the power input box rotates around the vertical shaft with the axis of a round sleeve as the center, and the forage grass cutting flatting mill can be immobile at the original position. When the tractor continues to run after making a turn, the rotation box is subject to forward traction and pulls the forage grass cutting flatting mill to work. When the vertical shaft rotation type drawing mechanism is in work, the supporting frame is put away and locked at 0 degree; after the work is finished, the supporting frame is placed down to be locked at 90 degrees, and the forage grass cutting flatting mill is supported.

Description

technical field [0001] The patent of the invention belongs to the technical field of agricultural machinery, in particular to a vertical shaft rotary traction mechanism of a forage harvesting and flattening machine. Background technique [0002] The traction mechanism of the existing traction-type pasture harvesting and flattening machine is rigidly connected to the tractor. This connection can ensure that the pasture harvesting and flattening machine can work normally under the traction of the tractor, but the pasture harvesting and flattening machine produces The steering resistance torque is large. When the turning radius is too small, the tractor wheels will interfere with the traction frame of the forage harvesting and flattening machine, increasing the turning radius of the tractor, which is not conducive to the machine's headland operation. The vertical shaft rotary traction mechanism provided by the present invention, the traction frame can realize large-angle turni...
