Revolvable and retractable boarding ladder with pedals for harvester

Abstract

A car ladder with rotatable and shrinkable foot pedals for harvesters is mainly composed of a car ladder frame, a foot pedal assembly, a pull rod, a tension spring, a connecting rod, a pin shaft, and a joystick, and its structural feature is that the foot pedal assembly Slidingly assembled on the ladder frame of the vehicle; the pull rods are respectively connected with the pedals of the pedal assembly by sliding assembly; one end of the tension spring is assembled on the ladder frame of the vehicle, and the other end is assembled on a foot in the pedal assembly. On the pedal; one end of the connecting rod is slidably connected to a pedal in the pedal assembly, and the other end is connected to the joystick through a pin assembly, and the joystick is placed in the hole of the limit plate. The invention simplifies the structure of the car ladder, reduces the volume, reduces the production cost, is convenient to operate, realizes the rotation and contraction of the pedals, and effectively reduces the overall width of the harvester.

Description

technical field [0001] The invention relates to a car ladder with rotatable and retractable pedals for a harvester, which belongs to the field of machinery. Background technique [0002] Most of the car ladders on the harvester developed in the domestic market are fixed or integral rotary. The fixed loading ladder is fixedly assembled on the harvester and cannot be moved or rotated. Since the pedals protrude from the outside of the whole machine, the width of the whole machine is increased. When harvesting, it is easy to knock down unharvested crops. The integral rotary loading ladder is slidingly assembled on the harvester. When loading, the loading ladder is rotated to the outside of the whole machine, and when harvesting, the loading ladder is rotated to the inside of the whole machine, which will not increase the width of the whole machine. The car ladder has complex structure, large volume and high cost. For this reason, we have invented a kind of simple in structure,...

Problems solved by technology

The fixed ladder is fixed on the harvester and cannot be moved or rotated. Since the pedals protrude from the outside of the whole machine, the width of the whole machine is enlarged. When harvesting, it is easy to knock down the unharvested crops

The integral rotary loading ladder is slidingly assembled on the harvester. When loading, the loading ladder is rotated to the outside of the whole machine, and when harvesting, the loading ladder is rotated to the inside of the whole machine, which will not increase the width of the whole machine. The car ladder has complex structure, large volume and high cost
