Farmer builds DIY seed metering system with 3D printed elements

Norfolk farmer Jonny Leech has used 3D printing to construct a exact maize seed metering system.

This method is crucial for constant crop efficiency and enhancing his farm’s patchy forage maize yields. With using additive manufacturing, Leech has made vital price financial savings whereas attaining related efficiency to the ready-made machines.

Designing and driving a seed metering system

For the optimum singulation of the seeds, which is vital to constant crop efficiency, a maize metering makes use of a vacuum to suck them into recesses dotted round a rotating disc. Then, in-row spacing will be adjusted by altering the velocity at which it spins. Usually, off-the-shelf variations price $600 per row.

To create an inexpensive various, Leech designed the system utilizing Solidworks and 3D printed the singulation system. “Probably the most difficult a part of designing the disc-based singulator was discovering a approach to management the vacuum so that every seed is launched down the tube at a exact level,” mentioned Leech. To unravel this downside, he positioned a strain gauge on the vacuum manifold to offer the proper strain for pulling seeds onto the disc.

Working by way of fifteen prototype designs, Leech managed to construct a unit that carried out to 99% singulation accuracy at 12 kph. Printing the elements for all six rows took Leech three months to finish. At a value of $70 in complete, 3D printing has supplied enormous price financial savings. 

Every singulator unit was later outfitted with a chain-and-sprocket drive from the rear press wheels. Whereas the pushed aspect makes use of a stainless-steel sprocket, Leech 3D printed a plastic sprocket for the opposite finish of the bicycle chain. The plastic sprockets managed the velocity of 70ha with out exhibiting any indicators of damage. Moreover, 3D printing the sprocket means Leech can manufacture a inventory of substances choices to change the sowing charge. 

Combining 3D printed plastic elements together with his personal chassis and different previous gear within the farm, your entire system in the long run solely costed Leech $12,000.

3D printing farming gear

3D printing is making its approach into farming. Beforehand, additive manufacturing has enabled streamline manufacturing of automated water sensor programs for aquaculture. The know-how has additionally helped rural farms in Myanmar to enhance farming effectivity.

To reuse out of date farming gear, a UK-based on-line spare half provider BuyAnyPart gives 3D printed half alternative service to farmers. Shifting the business ahead, 3D printing has additionally led to new farming practices comparable to open supply farming gear and compact shelving models for vegetation.
