Traction connection device for tractor and agricultural implement and agricultural machinery

Abstract

The invention provides a traction connecting device for a tractor and an agricultural implement, which comprises a lifting device installed on the tractor, a butt joint device for installing an agricultural implement and a valve block set used for being in butt joint with a pipeline of the tractor and the agricultural implement, wherein the valve block set comprises a first valve block installed on the tractor and a second valve block arranged on the butt joint device, the first valve block is connected with the second valve block in a matched insertion mode, the lifting device comprises a first support fixedly connected with the tractor, a traction mechanism pivoted to the first support and a lifting mechanism used for driving the traction mechanism to rotate and ascend and descend, the traction mechanism is provided with a traction hook driven by the traction mechanism to move, the traction hook is detachably connected with the butt joint device, during connection, the lifting mechanism drives the traction mechanism to rotate and ascend so as to drive the butt joint device to ascend to the butt joint height position, and then the traction mechanism drives the traction hook to drive the butt joint device to get close to the tractor, so that the first valve block and the second valve block can be connected in a matched insertion mode. The traction connecting device realizes quick connection between the tractor and the agricultural implement 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...

AI Technical Summary

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
