Abstract [en]

Korngården AB is the biggest hop producer in Sweden. They are

located in the south of the country and their farm currently

consists of 5000 m2. Korngården AB is a newly founded company and

is just starting up its business. The next step forward in their

development is investing in a hop harvester. Therefore, in this

thesis a first draft for a portable hop harvester is presented.

The goal of this project was to design a machine that can be

easily transported between hop farms in the vicinity and harvest

50 – 100 bines per hour.

Starting up this project a study of hop harvesting solutions was

made. To give this project a target I was provided with a

specification of user demands by Korngården AB. During the concept

generation different solutions were developed and with the help of

a Pugh matrix the solutions was compared against each other. The

chosen concept was 3-D modeled in the CAD program SolidWorks.

During this process a number of companies was contacted to get an

idea of what this hop harvester would cost to produce. This turned

in to the cost estimate which was one of the goals of this thesis.

From the 3-d models assembly drawings was created.

The result of this thesis is a hop harvester that strips the bines

using steel picking fingers that hits the cones and leaves of the

bine. The cones and leaves are then separated using a series of

tilted rubber bands. When exiting the striping section the bine

will be chopped into smaller pieces using a wood chipper. At the

moment the cost estimate shows that the hop harvester would cost

around 200 000 sek to produce which is 25 000 sek more than what

Korngården AB specified in their specification of user demands.
