Abstract

The bachelor's thesis is focused on the design of a single-row potato planter carried in front of a small tractor. The maximum dimensions of the device should not exceed length / width / height = 1000/750/900 mm. The volume of the hopper is set at 40 l. The maximum spacing of the planting trays installed to the chain is 300 mm.

The single-row potato planter consists of the following parts: frame, hopper, feed pipe, positioning foot, struts, spreading blades, swath blades and drive wheels. Furthermore, the planter consists of two sprockets, which are connected by a chain to the carriers. The first sprocket is slid on a drive shaft, which is driven by drive wheels rolling on the ground. The second sprocket is slid on a driven shaft, which is mounted in bearing housings and is tensioned with two tensioning bolts.

From a theoretical point of view, I will describe what this machine is for, what it looks like, what its advantages or disadvantages are, what principle it works on and so on.

The bachelor thesis contains strength calculation of the chain, technological calculations and calculations of selected parts.
