• the present invention relates to specially developed technical and functional enhancements introduced into the subsets that configure a machine for collecting and cleaning coffee beans in coconut.
• the present coconut coffee bean harvester is classified as a trailing machine to perform three distinct operations: a) collection of previously raked coconut beans; b) perform a complete cleaning process separating the grains (seeds) from other disposable parts; and c) storing in a bucket provided on the machine itself, where said bucket has means so that it can be tilted for rapid unloading at the desired time.

• the machine includes a first cardan shaft to be coupled to the tractor PTO, and thus different subassemblies are driven simultaneously, starting with a conveyor belt of the material to be processed.
• This set is designed to provide different advantages, ie it is a treadmill that works with a certain inclination so that only its front end touches the floor, where side skates give means for this end to copy all soil irregularities, accompanying its profile during the movement of the machine on the material to be harvested which, in turn, consists of coffee beans (coconut) and others.
• This retraction occurs at a considerable speed, as the conveyor has several rubberized transverse vanes, which act as true blades, continuously harvesting the material and throwing it over another two overlapping sets defined as stirring set and sieve set.
• This route begins a first step of cleaning by suction through side ducts and a fan.
• the stirring assembly shakes the material to loosen the remaining bonds between coffee beans and their branches.
• the grains pass through two vibrating screens and are then collected by other sets and driven to an upper hopper, and in this course another suction set performs the last cleaning step. Completely cleaned grains are packed in said bucket, which in turn has the resources to be tilted at the time of unloading.
• the constructive shape and arrangement of the subassemblies on the one-piece chassis make it possible to achieve a compact and cost effective harvester. substantially low for small and medium producers.
