Abstract

An automatic seedling plate van based on double-chain transmission comprises a machine frame, a fetching device, a lifting device, a placement mechanism, a traveling mechanism and a control system. The fetching device comprises grabbing fingers, a transmission chain mechanism, an unpowered roller mechanism and the like and is used for achieving fetching of seedling plates. The lifting device comprises a guide mechanism, a chain transmission mechanism, a tensioning mechanism and the like and is used for achieving vertical movement of the fetching device and three-dimensional placement of the seedling plates. The placement mechanism comprises a support and supporting boards, and the paired supporting boards are arranged at equal intervals. The traveling mechanism is of a symmetrically distributed four-wheel system structure, and two driving wheels are controlled by a direct current geared motor in a directional differential mode to travel and turn. The control system comprises a loading system and a traveling system and is composed of a single-chip microcomputer, various sensors and the like. Automatic loading and tracking moving of the van are achieved by detecting signals of the control system. Integration of loading, unloading and transportation of the seedling plates in industrialized seedling production is achieved, and automatic carrying of the seedling plates can be completed.

Description

Technical field [0001] The invention relates to an automatic transport vehicle for seedling trays, in particular to an automatic transport vehicle for seedling trays based on double-chain transmission suitable for industrialized seedling raising enterprises. Background technique [0002] In factory planting, automated machines such as automatic grafting machines, seedling boxes, automatic seeding systems, and environmental control systems are widely used. However, between these agricultural machinery, the seedling trays are mainly transported manually, which is not highly mechanized, low in efficiency and high in cost. There are many researches on handling devices abroad. Most of the seedling trays are transported to the truck by manpower, or stacked in rows, and then transported by tractor or manpower. However, these structures are complex and expensive, and it is difficult to be applied in small-scale enterprises. Therefore, in combination with the development trend of mechan...
