Single-row chain potato planter is intended for the mechanization of planting potatoes. It is aggregated with motoblocks and mototractors with a capacity of at least 6 liters. p.

The principle of operation of the potato planter:

The drive of the landing mechanism is actuated by the support wheels through the drive shaft. The torque from the drive shaft is transmitted to the landing mechanism through a chain transmission equipped with a roller tensioner. The tensioner is necessary to prevent sagging of the chain after adjusting the landing step. Adjustment is made by moving the chain to additional sprockets.

The design of the main unitspotato planter for a walk-behind tractor:

Support wheels and drive shaft:
ground-track wheels have a diameter of 340 mm, rim thickness - 3 mm, width - 110 mm;
the diameter of the drive shaft is 25 mm.
Landing mechanism
The main node of the potato planter is a bunker with a shaft in which the planting mechanism is located. In the mine there are support stars with a chain and baskets. The landing mechanism uses a PR-12.7 — 18.2 drive chain (ant, number of links 98), 12 baskets with a diameter of 50 mm are installed on it.

The hopper for potatoes with a capacity of 20 liters is made of sheet steel with a thickness of 0.8 mm.

The keel-shaped opener of the potato planter is made of sheet steel with a thickness of 2 mm. The keel of the opener is reinforced, thickness - 3 mm.

To wrap the planted potatoes and create a soil ridge on a frame made of a steel corner 32x32x3 mm, adjustable disc hillers with a diameter of 275 mm and a thickness of 2 mm are installed. Smooth and reliable rotation of each disk is ensured by a pair of 202 bearings.

Towing unit
Depending on the model of the traction unit, the potato planter can be equipped with various towing units. The towing unit is attached to a special bracket with the help of bolted connections. To ensure stable operation of the potato planter on uneven soil, the bracket is fixed on a movable sleeve.
