Abstract:
A load moving trolley, comprising a sub-trolley frame (1), a raising and lowering assembly, a hook structure (4), and a travel assembly (2). The sub-trolley frame (1) comprises a top panel (1-1) and side panels (1-2). The top panel is rectangular, and the side panels are arranged vertically and surrounding the edge of the top panel. The side panels and the top panel jointly define the sub-trolley frame (1), in which is formed an accommodation slot (1-6). The hook structure (4) is arranged on the raising and lowering assembly, and the raising and lowering assembly and the travel assembly (2) are arranged in the accommodation slot (1-6), the raising and lowering assembly being able to rise or lower relative to the sub-trolley frame (1). The load moving trolley is arranged above cultivation frames of a multi-level standing cultivation rack. The hook structure is arranged on the raising and lowering assembly, and the raising and lowering assembly is able to rise or lower relative to the sub-trolley frame, and thereby complete automatic suspension of an irrigation device or a photography device. The travel assembly is able to move along the length direction of the multi-level standing cultivation rack and drive the irrigation device or the photography device to automatically irrigate or automatically photograph plants in the cultivation frames. The invention features a high level of automation and does not require climbing operations by human workers, thus providing working efficiency.
