Seedling tray moving device for vegetable transplanting machine

Abstract

The invention relates to a vegetable transplanting machine seedling tray moving device, and belongs to the agricultural and forestry machinery technology field. The device comprises a fixed stand and seedling tray clamping mechanisms. At least one side of the fixed stand is equipped with a chain transmission mechanism composed of upper and lower horizontal shaft chain wheels driven by a vertical stepping motor and chains surrounding the chain wheels. The chains at two sides are fixedly connected with corresponding ends of an upper horizontal clamping groove plate and a lower horizontal clamping groove plate of a seedling tray stand. Two ends of each clamping groove plate are fixedly connected with two vertical side plates respectively. An upper horizontal shaft and a lower horizontal shaft go through the two vertical side plates and the two vertical side plates, the upper horizontal shaft and the lower horizontal shaft form a moving pair. The upper horizontal shaft and the lower horizontal shaft are fixedly connected with an upper end and a lower end of a vertical connection plate. An inner wire thread insert is fixed on the connection plate. The wire thread insert and a horizontal screw rod form a screw pair. The screw rod is in transmission connection with a transverse stepping motor installed at one side of the vertical side plate. The seedling tray clamping mechanisms are distributed the horizontal shaft at intervals. The seedling tray moving device solves the problem of rapid, accurate and automatic moving of seedling trays through a simple and reasonable vertical and horizontal combined movement mechanism, and therefore the seedling tray moving device lays the foundation for design and manufacturing of a vegetable transplanting machine taking seedling automatically.

Description

technical field [0001] The invention relates to a seedling tray moving device, in particular to a seedling tray moving device for a vegetable transplanting machine, belonging to the technical field of agricultural and forestry machinery. Background technique [0002] As far as the applicant knows, the existing vegetable transplanting machines all need to manually take the seedlings and then feed the seedlings. For example, in the technical solutions disclosed in Chinese patents with publication numbers CN204119785U and CN204217400U, the vegetable transplanting machines are semi-automatically operated and need to be completed manually. Taking seedlings and feeding seedlings is not only labor-intensive, but also has extremely low transplanting efficiency. In addition, rising labor costs have led to an increase in vegetable production costs. [0003] The seedling trays in the prior art have hole seedlings distributed at regular intervals vertically and horizontally. When trans...
