Self-rescue device of self-propelled agricultural vehicle

Abstract

Provided is a self-rescue device of a self-propelled agricultural vehicle. The self-rescue device includes an upper leg mechanism and a lower leg mechanism; the upper leg mechanism is connected with awheel hub of a slipping wheel of the self-propelled agricultural vehicle; one end of the lower leg mechanism is hinged to the upper leg mechanism, the other end of the lower leg mechanism is providedwith a self-rescue boot, and the lower leg mechanism swings freely along a hinge joint to make the bottom surface of the self-rescue boot parallel to the ground consistently; when the upper leg mechanism and the lower leg mechanism are positioned on the same line, the sum of the lengths of the upper leg mechanism and the lower leg mechanism is larger than the wheel radius of the self-propelled agricultural vehicle; when the self-propelled agricultural vehicle is driven forwards, the upper leg mechanism rotates together with the slipping wheel to drive the lower leg mechanism to move until theself-rescue boot of the lower leg mechanism is in contact with the ground and supports the slipping wheel off the ground to move forwards to achieve self-rescue.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a self-propelled agricultural vehicle self-rescue device for field crops. Background technique [0002] The self-propelled high-gap boom sprayer for field operations has a wide range of operations and high efficiency, and has gradually been accepted by farmers in recent years; however, due to the harsh environment of field operations, especially paddy fields, the wheels often slip and stop moving, requiring a tractor Entering the field for rescue will inevitably crush the crops. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a self-propelled agricultural vehicle self-rescue device, which can be installed to relieve the skid when the agricultural vehicle slips. [0004] In order to achieve the above object, the present invention provides a self-rescue device for self-propelled agricultural vehicles, including: [0005] an ...
