Example Embodiment

[0028] The patent of the present invention will be further explained below in conjunction with the drawings. The automatic track-changing walking chassis of the leafy vegetable harvesting robot of the present invention, such as figure 1 , 2 , 3 and 4. The motion mechanism includes a traveling wheel, a traveling wheel fixing frame, a driving device, a fixing bolt and a lock nut (20). The said traveling wheel fixing frame is a universal wheel rotating frame, the upper part of the traveling wheel fixing frame is a cylindrical platform and a hollow frame, and the four traveling wheel fixing frames are respectively fixed on the rail car chassis by fixing bolts and lock nuts (20). The four corners of 1) are called walking wheel fixing frame 1-4; the walking wheels are double-sided track wheels, and the walking wheels are fixedly placed in the middle of the walking wheel fixing frame, respectively called walking wheels 1-4 The driving device is composed of a driving motor (16), a syn...

Abstract

The invention relates to an automatic rail changing walking chassis of a facility leaf vegetable harvesting robot. According to the technical scheme, the automatic rail changing walking chassis comprises a rail car chassis, a movement mechanism, a steering mechanism, a control mechanism and a storage battery. The movement mechanism is used for driving a rail car to move and stop on rails and driving all walking wheels to rotate and walk in the rail changing process. The steering mechanism is used for controlling all the walking wheels to conduct steering work for determining angles three times in the rail changing process. The control mechanism is used for positioning all the working positions of the rail car, controlling the timing sequence matching of the movement mechanism and the steering mechanism and controlling the displacement in all the movement processes. The automatic rail changing walking chassis can be used for bearing other operation machines to complete conveying work and can move along the rails stably and quickly to precisely stop at a set stopping position at the tail ends of the rails, so that various complex functions of parallel rail changing work and the like are achieved autonomously. The automatic rail changing walking chassis is simple in structure, compact in car body, small in occupied area in the rail changing process, free of other auxiliary facilities, high in degree of automation and capable of conducting full-automatic or remote control greenhouse operation.

Description

technical field [0001] The invention relates to the field of agricultural robots, in particular to an automatic track-changing walking chassis and a track-changing method of a facility leaf vegetable harvesting robot, which are used for walking and changing tracks on parallel tracks in a greenhouse. technical background [0002] The rail car is a kind of driving route that can move along the track and use the track to achieve the purpose of logistics transportation. The rail car can automatically drive along the planned route without driving, can do acceleration, deceleration and braking planning, and the parking position is accurate. Compared with other automatic guided vehicles (AGV), rail cars have the characteristics of simple control, reliability and good adaptability. [0003] In the production of facility agriculture, solar greenhouses only rely on solar radiation to obtain heat in cold winter, which cannot fully meet the needs of crop growth and development. Heating...
