Abstract
The present invention consists of a device for more efficient harvesting of the ripe fruits of coffee trees, comprising an oscillating mechanism characterized for integrating a set of oscillating parallel cables causing the fruits to be pulled off from a line of branches full of ripe coffee and the coffee beans to progressively fall into the cylinder receiving the coffee fruits. The device prevents the operator from being in contact with the fruit, leaves or branches thus reducing the labour force used for the harvest, it also eliminates the risk for them to be bitten by any worm or insect. At the same time, by using the device hand contact with the coffee fruit is avoided, thus also avoiding crossed pollution of the fruit and increasing the quality of the fruit harvesting.
Description
DEVICE FOR HARVESTING COFFEE HAVING AN OSCILLATING MECHANISM
OBJECT OF THE INVENTION The present invention may be included in the agricultural technical field, in particular, that of fruit harvesters.
More particularly, the object of the invention refers to a device for more efficiently harvesting ripe fruits from the coffee tree, and by means of oscillating cables and a rectilinear movement, making the fruits to fall from a branch line full of ripe coffee.
BACKGROUND OF THE INVENTION
It is known that coffee plantations are currently facing problems out of manual harvesting, so this device for harvesting coffee with oscillating rectilinear movement is intended to replace labour force which is becoming more and more scarce, and provides a mechanism which pulls the fruits off towards a receiving cylinder, thus guaranteeing a faster and more accurate work for which the device is used. Different manual technological elements have been developed for harvesting coffee, but these are not efficient and their cost is not accessible for the small producer. Many of these coffee harvesting machines work with an internal combustion engine, generating polluting carbon monoxide gas. Countries as Brazil use mechanical coffee harvesters coupled to a tractor, but the topography is flat and allows efficient harvest without any problem.
Coffee belongs to the Rubiaceae family and to the genus Coffea, and there are several coffee species. The aerial morphology of the coffee plant has two types of shoots: orthotropic ones, growing vertically and comprising the main stalk and the suckers. Additionally, it has the secondary or plagiotropic shoots, which grow horizontally and comprise primary, secondary and tertiary branches. Here in the primary branches is where blooming and fruits take place in several groups, at about 5 to 10 centimetres between fruits and with several primary branches full of fruits. The main difficulty at the harvest moment is that in the same primary branch there can be ripe fruits, green fruits,
leaves and sometimes flowers, and coffee production from Latin America is produced in very steep regions, hence the difficulty of the harvesting.
Some current solutions such as those described in patent US4538405, include a box comprising two spindles that rotate and hit the fruits in the branches, thrust bearings and vibrating units, which are not easy to use and can affect the coffee plant physiologically.
Therefore, considering the previous documents, it is necessary to find alternatives directed to allow a more homogeneous harvest of the ripe beans and pulling the fruits off efficiently.
DESCRIPTION OF THE INVENTION The present invention provides a device integrating the needs of the harvesting process of the ripe and semi-ripe beans from the coffee tree branches, specifically mechanical harvest of the beans during harvest time, wherein labour force is not cost effective and is scarce. Therefore, an aspect of the invention refers to a device for coffee harvesting characterized in that it comprises:
- a set of extending cables with a mechanical regulator and an oscillating rectilinear movement at the base thereof, allowing the coffee beans to fall.
- a set of hooks arranged along the cables,
- a collecting container for the coffee beans having a box incorporated therein, and
- a perpendicular attaching piece between the set of cables and the collecting container. Preferably, the mechanical regulator comprises a system for height and tension adjustment of the set of extending cables.
The oscillating cables are placed over the branches and due to the rectilinear movement thereof, it causes fatigue to the branches, causing the ripe coffee beans to progressively fall by gravity into the receiving cylinder. The device described in the present invention may be used in a homologous way for harvesting several fruits from fruit trees, such as for example, but not limited to, collection of from plum, cherry, mango, olive, apricot, apple, pear, loquat, tamarind, avocado, walnut, hazel-nut, almond, cashew, breadfruit, cherimoya or pomegranate trees. The present device may be adapted to the morphology of the fruit trees by adjusting the set of hooks of the oscillating mechanism to the tree branches. As a consequence of the physiological fatigue, the peduncle of the fruit is weakened and the oscillating movement caused by the present device allows pulling off the fruits, and those fruits being in the optimum maturation conditions fall by gravity. DESCRIPTION OF THE DRAWINGS
FIG. 1 . It shows a view of the front section of the device of the invention.
FIG. 2. It shows an enlarged view of the side section of the device of the invention.
PREFERRED EMBODIMENT OF THE INVENTION
The following is the description of a preferred embodiment of the invention based on the attached figures.
FIG. 1 shows the oscillating cable (4) which, together with a collecting cylinder (3), allows the beans to fall and be stored. The supports (2) work as mechanical regulators by means of which the cables (4) must oscillate. The fixed links (5) allow the mechanism free movement and reduction of the oscillation requirements transmitted to the coffee plant branches by the cables (4), which are coupled to the fruit-receiving cylinder (3a).
FIG. 2 the supports or pin (2) allows adjusting and positioning the oscillating cables (4), depending on the height of the coffee tree, fixed to a clamp or link (5) so as to reach or regulate the intended position.
