A System to Simplify the Use of Mounted Shakers for Harvesting Olives and Dry Fruits

Abstract

The shakers for harvesting olives and dry fruits have reached a high standard and their use is increasing rapidly. In order to satisfy the different demand, manufacturers offer a wide range of shakers, from the more expensive self-propelled ones to those to be mounted on the tractor’s power lift, with shaking headers of different mass and size, suitable for the different orchard characteristics. Self-propelled shakers have high steering capacity and optimum visual field for the operator, so their working capacity is very high with respect to that of mounted shakers, which are less expensive but have lower steering capacity and a limited view on the header. Therefore the approaching of mounted shakers to the plant and the fastening of the header to the trunk or branch of the tree is more difficult, and a second operator to pilot the tractor driver is needed, in order to increase the machine working capacity and to avoid plant and/or shaker damages. This paper proposes to use a system composed of a CCD video camera, installed on the frame of a mounted shaker and connected to a TFT monitor, fitted in the tractor cab. Comparative tests with and without the above system were carried out. The video camera was mounted on the shaker frame. The system is relatively cheap, user-friendly and can be mounted on any shaker. It provides the driver with an easy view of the lower dead angle and increases the working capacity and productivity of the machine.
