Tractor and agricultural machinery traction connection device and agricultural machinery

Abstract

The application provides a traction connection device for a tractor and an agricultural implement, including a lifting device installed on the tractor, a docking device for installing the agricultural implement, and a valve block set for connecting the pipeline between the tractor and the agricultural implement. The first valve block and the second valve block arranged on the docking device, the first valve block can be mated with the second valve block, the lifting device includes a first support fixed to the tractor, pivotally connected to the first support The traction mechanism on the seat and the lifting mechanism used to drive the traction mechanism to rotate and lift. The traction mechanism is provided with a traction hook that moves under its drive. The traction hook is detachably connected to the docking device, and when connected, the traction mechanism is driven by the lifting mechanism. The mechanism rotates and rises to drive the docking device to rise to the docking height position, and then drives the traction hook through the traction mechanism to drive the docking device close to the tractor so that the first valve block and the second valve block are mated and plugged. The application realizes the fast connection between the tractor and the agricultural machinery without manual operation.

Description

technical field [0001] The present application relates to the field of mechanical equipment, in particular to a traction connecting device for a tractor and an agricultural implement and an agricultural machinery. Background technique [0002] In the field operation machinery, except for a few self-propelled machinery and special-purpose machinery, the rest almost all use an agricultural machinery composed of tractors and agricultural implements. When not in use, the tractor and agricultural implements can be separated, so that It can greatly improve the utilization rate of the tractor, so that the tractor can be connected with different agricultural implements to carry out operations under different working conditions. At present, the agricultural machinery and tools used are usually directly connected to the tractor manually. In this way, the electrical, hydraulic and other pipeline interfaces need to be disconnected artificially when disconnected. Every time they are reco...

Problems solved by technology

At present, the agricultural machinery and tools used are usually directly connected to the tractor manually. In this way, the electrical, hydraulic and other pipeline interfaces need to be disconnected artificially when disconnected. Every time they are reconnected, the pipeline interfaces need to be reconnected manually. The operation is time-consuming. Laborious, with risk of injury and incorrect connection of connectors
