A tractor power output control device

Abstract

The invention relates to a power output operating device for a tractor. The power output operating device comprises an operating lever, a connecting arm, a pull rod, a rocker arm and a push pin, wherein the operating lever is integrally fixed with the connecting arm through a hinge joint seat; and the push pin extends into a rear axle transmission case. The power output operating device is characterized in that one end of the rocker arm which is arranged horizontally is non-rotationally connected with the push pin; the push rod is in vertical hinge joint between the connecting arm and the other end of the rocker arm; a rectangular hole is formed on a seat plate; a jointed shaft stretches over the rectangular hole, and the two ends of the jointed shaft are fixed together with the seat plate; the operating lever is hinged with the jointed shaft through the hinge joint seat; a pressure plate for shielding the rectangular hole is fixed on the seat plate, and is provided with a hinge joint seat hole; the size of the hinge joint seat hole is slightly larger than the physical dimension of the hinge joint seat; and the hinge joint seat penetrates through the hinge joint seat hole. The operating lever is hinged on the seat plate on the side edge of a driver seat, so that the leg accommodating space in a cab is large, and people can get on / off conveniently; a driver can operate the operating lever conveniently in a labor-saving way; and the rectangular hole is shielded by using the pressure plate, so that the leak tightness of the cab is high.

Description

technical field [0001] The invention relates to the arrangement or installation of a power plant control mechanism on a general vehicle, in particular to a tractor power output control device. Background technique [0002] We know that tractors are indispensable power machinery for agricultural mechanization. The tractor power take-off device is a working mechanism that transmits the power of the tractor engine to agricultural implements (such as the cutter and reel of the harvester, the rotary tiller shaft of the rotary tiller, etc.) through the power take-off shaft arranged on the rear axle. Its power output control device is to control the power output shaft to obtain high and low speeds. The tractor power output control device mainly includes a joystick, a connecting arm, a pull rod, a rocker arm, and a dial pin. One end of the arm is hinged, and the other end of the rocking arm is non-rotatably connected with the dial pin, and the dial pin stretches into the rear axle...

AI Technical Summary

Problems solved by technology

Due to the need for a certain length of space when the joystick is shifted to move forward and backward, the rectangular hole in the front of the seat panel is relatively large, resulting in poor sealing of the cab

In addition, the control end of the joystick is set next to the driver's left leg, and the position of the driver getting on and off the car and resting his legs is limited; the driver needs to lean forward to operate the joystick, which is inconvenient to operate.
