Problems solved by technology

However, in actual operation, due to the operator's misoperation, when the lifting operation is not carried out, or when the lifting height is not enough, it will start to turn. Since the agricultural machinery is still combined with the soil at this time and is in a working state, so the steering at this time, the agricultural machinery Side thrust can damage agricultural implements and endanger the safety of relevant personnel

Abstract

The invention discloses a tractor steering and lifting linkage device. The device comprises a lifting base, an operation rod is connected with the middle of the lifting base in a sliding mode, a direction gear is connected with the outer periphery of the operation rod in a toothing mode, one side of the operation rod is connected with one end of a front axle, an inner gear is connected with the middle of the operation rod in a toothing mode, a screw is sleeved with the middle of the inner gear, a steering sensor is in rivet connection with the middle of the front axle, a control panel is connected with the middle of the left side of the lifting base in a clamped mode, a controller is welded to the middle of the control panel, a lifting oil cylinder is installed below the lifting base, a lifting valve is fixedly connected with the right side of the lifting oil cylinder through a bolt, and a lifting sensor is in rivet connection with the bottom of the left side of the lifting oil cylinder. The device is simple, reasonable and easy to use through an electronic control system, when an operator does not conduct lifting control but conduct steering operation, a lifting mechanism automatically lifts an agricultural implement, safety is improved, and the linkage device is used for a tractor steering operation and lifting system.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a steering and lifting linkage device for a tractor. Background technique [0002] For the development of increasingly mature wheeled tractor technology, people have a great demand for ergonomic comfort and automatic operation on the basis of meeting functional requirements. For the development of agricultural machinery, the design concept of error-proof and fool-proof It is also subtly affecting the development of this industry. [0003] At present, domestic tractors are all rear-mounted agricultural implements. Since the lifters of the suspension mechanism adopt independent mechanical or electronically controlled structures, they have no relationship with the steering system. Generally, the lifting joystick or electric control button is operated first to make the lifting control valve control the oil circuit and work on the oil cylinder to achieve lifting. When ...
