A manipulate linkage device of a tractor

Abstract

The invention relates to a tractor control linkage device, a lifter control assembly, a handle and a rocker arm, wherein an electric push rod is arranged at the rocker arm; The auxiliary clutch control assembly comprises a handle and a rocker arm, an electric push rod is arranged at the rocker arm, and a PTO electric push rod conversion relay is connected with the electric push rod of the auxiliary clutch control rocker arm; Steering linkage switch, set steering PTO linkage mode switch and lift linkage mode switch; Steering The PTO linkage mode switch is provided with a first common terminal and a second common terminal at both ends, respectively, for steering. PTO- A lif linkage mode switch is provided with a third common end and a fourth common end at both end, and a lifting rocker arm travel switch is connected between that second common end and the third common end. The manipulate linkage device of a tractor realizes the linkage control through the combination of electromechanics,and has the advantages of simple operation, diverse modes, large application range, low production cost, economy and practicality.

Description

technical field [0001] The invention relates to the technical field of a tractor control linkage structure, in particular to a tractor control linkage device. Background technique [0002] For agricultural machinery for mechanized operations, a suspension mechanism is usually installed at the rear of the tractor, and the hydraulic device controls the action of the suspension mechanism, so that the agricultural machinery is in the working position of lifting or various plowing depths, and the output power of the tractor is provided to the agricultural machinery. tools to perform various tasks. [0003] Existing linkage devices: one can only be realized under the premise of an electronically controlled lifter and a programmable controller, and the functions cannot be switched, and the mode is single; the other is based on the premise that the PTO is an electronically controlled wet clutch structure It can only be realized under the control of the mechanical PTO, and does not ...

AI Technical Summary

Problems solved by technology

[0003] Existing linkage devices: one can only be realized under the premise of an electronically controlled lifter and a programmable controller, and the functions cannot be switched, and the mode is single; the other is based on the premise that the PTO is an electronically controlled wet clutch structure It can only be realized under the control of mechanical PTO, and it does not involve the lifting-PTO linkage function under the control of mechanical PTO

The third type is purely mechanical connection, the functions cannot be switched, and the mode is single, and it does not involve the working mode of reverse independent and linkage switching with lifting. Not suitable for special working conditions such as fertilization and spraying

The fourth type is still a purely mechanical connection, the functions cannot be switched, the mode is single, and it does not involve the working mode of reversing independent and linked with PTO. Sometimes special circumstances, not applicable, the scope of application is still small
