DE388954C - Machine for extracting the palm fruits from the fruit clusters - Google Patents

Description

There are devices for releasing the palm fruits (Elaeis guineensis) from their Fruit clusters known, in which the latter in a box-like housing of S hinged arms are processed, which hold the fruit by flinging the clusters of fruit around separate from these. Since the angular, egg-shaped fruit of the oil palm is very delicate is, are used in these devices

ίο the fruits, almost invariably damaged. However, this has the major disadvantage that a fermentation or acidic process occurs immediately, which affects the fruits very unfavorably. Finally, with this device mostly not all fruits removed from the perennials.

There are also devices for peeling pulses with a cross-section Arched rust-like trough known through which arms strike from below. the Trough runs in these devices. down to a point and grab the flapping arms so far into the hollow that these devices for releasing the palm fruits from their perennials are unsuitable.

The invention relates to a device tion for separating the palm fruits from the fruit clusters, which is also a A trough-shaped grate and eye arms for processing the fruit clusters are provided are, in which, however, the abovementioned inconveniences are avoided in that the trough-shaped which receives the fruit clusters Grate is given a semicircular cross-section, the center of which is perpendicular lies above the shaft of the flapping arms. As a result, the striking arms • the tuft of fruit in the hollow is given a circular and rolling motion so that the Clusters hit on all sides by the flapping arms and so quickly and safely by the fruit to be freed. As a result of the semicircular cross-section of the trough, however, can also the fruit is not crushed or smashed.

On the drawing the new device is in

Fig. Ι in a side view and in

Fig. 2 shown in plan.

The trough a into which the fruit tufts are placed is exactly above the center of the striking mechanism b. The grate c of the trough has an arcuate cross-section, the center of which is far outside the impact

poor so that they enter the trough only a little when the machine is running. The fruits chopped off by the beater arms pass through the grate onto the conveyor cloth d, through which they are fed to a collecting container *, which is provided with a conveyor screw as usual. When the fruit falls off the conveyor cloth, shrub residues, sand and other impurities are removed in the known manner by means of a wind sweep /.
