Description

Olive picking shovel.

Object of the invention

The present invention relates to a shovel intended to be attached to a tractor or agricultural trailer, specially designed for the collection of olives, specifically for the transfer of them from the ground to the interior of the cited trailer.

The object of the invention is to facilitate very considerable the maneuvers of load of said shovel.

Background of the invention

As is known, in the olive harvest the olive trees are subjected to a process of bending or vibrating so that the release of the olives occurs, which fall to the soil, from where they must subsequently be collected and loaded into a agricultural trailer for later cleaning and processing.

Olives usually fall on a tarp, plastic sheet or other material that covers the floor, for prevent them from mixing with the earth, and from here they are transferred to a shovel that can be mounted on an agricultural tractor or on the trailer itself associated with said tractor, so that it is said shovel responsible for raising olives from ground level until unloading above the trailer.

This solution presents in practice and how fundamental problem the difficulty of transferring the olives from the ground to the inside of the shovel, since if use a shovel of dihedral configuration, which can support one of its edges on the ground, so that the olives are simply sweeps inwards, the loading capacity of the shovel It is small and the number of maneuvers to be performed with it very high, while using a shovel with greater capacity load, for example configure a receptacle prismatic-rectangular, open superiorly, the olives can no longer be swept inwards, but instead they must be paled with an important participation by the hand of work.

Description of the invention

The pickup blade that the invention proposes solves the problem fully satisfactorily previously exposed, so that with a high capacity of load, allows that load to be produced in the simplest way possible, specifically by "sweeping" the olives on the floor.

To do this and more specifically, this blade is constituted from a receptacle basically prismatic-rectangular, open top, without practically capacity limitation, which is defined exclusively for the power of the lifting mechanisms to unloading of said receptacle within the agricultural trailer, with the special feature that said receptacle is framed by two lateral arms that emerge from a wide tray of width coinciding with that of the aforementioned body or receptacle and with any surface deemed convenient, so that tray and through the aforementioned arms joins articulated to the rear face of the body, at a medium level in height thereof, with the special feature that the front face of said body, the one corresponding to said tray, is curved-convex, having as its axis of curvature the axis of tilt of the arms, so that the tray is able to be level horizontal and lower, as an extension of the lower base of the receptacle body, and cylinder-driven ascending lateral that act on the mentioned arms, until the bottom of it reaches the mouth of the receptacle, without loss of contact with the front surface of the latter, is say no possibility of falling for olives, which neither they can fall by the ends of the trays because they They have container partitions for that purpose.

In this way and with the tray located on the soil, the olives can be swept into the same, and after filling it can be emptied on the receptacle constituted by the body, returning again to the horizontal and receiving position, and repeating this cycle so many times as necessary until the receptacle is filled later, at which time the lift will occur for unloading on the agricultural tractor.

According to another of the characteristics of the invention it is provided that said tray be foldable at in order to reduce its volumetric occupation in situation inoperative.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to a representation schematic in perspective, an olive picker shovel performed in accordance with the object of the present invention.

Figure 2.- Shows a schematic profile of the set represented in the previous figure, in the same position of the shovel, which allows the sweeping of the olives inwards Of the same.

Figure 3.- Shows a similar representation to figure 2, in which the blade appears in a situation of unloading of its tray on its larger capacity receptacle.

Figure 4.- Shows, finally, a profile similar to that in figure 2, in which the blade tray appears in folded situation.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the olive picking shovel that is recommended is structure from a body (1), determinant of a wide receptacle that tends to the rectangular prism, of considerable capacity, endowed with a rear wall structure (2) that gives it enough rigidity to allow its fixing to the lifting means of the load, whether it be the tilting arms of an agricultural tractor or of a mechanism of similar elevation coupled directly to the trailer, logically with capacity to support the load that supposes the total filling of the receptacle defined by the body (1).

This body (1) is complemented by a tray front (3), of width coinciding with that of said body (1) and which extends sharply forward, said tray being (3) subsequently closed by the front wall of the body (1), and counting with lateral containment partitions (5) high progressively decreasing towards its free limb, partitions that subsequently extended in arms (6) that frame the body (1) and that they finally articulate themselves to it through a rear axle (7), preferably materialized in two bolts coaxial

The arms (6) are assisted by respective hydraulic or pneumatic cylinders (8) that allow tilting of the tray. The front wall (4) of the body (1) is curved-convex, specifically it is a cylindrical wall whose axis of curvature is the axis of tilt of the arms (6).

According to this structuring the shovel Picker is capable of showing the position shown in the Figures 1 and 2, in which the tray (3) rests on the ground and in which olives can easily access inside the same by direct sweeping on the ground or by any other medium, and once the tray (3) has the load of olives appropriate, the actuation of the cylinders (8) causes the raising it to the limit situation shown in the Figure 3, in which the rear wall of the tray, up to that moment constituted by the front wall (4) of the body (1), passes to be below the bottom of the tray (3) and in which consequently said tray unloads by simple gravity on the receptacle defined by the body (1). This cycle will be repeated. as many times as necessary until the receptacle is loaded (1), and after said load will be when the shovel as a whole is raised above the agricultural trailer, for unloading inside the latter.

It only remains to note that, as note especially in figure 4, the tray (3) is fragmented into three sectors, related to each other through articulated joints (9), which allow said tray to adopt the extended situation shown in figures 1, 2 and 3, corresponding to the normal working situation of the shovel, or a folding situation, the one shown in figure 4, suitable for dramatically reduce the volumetry of the set in situation inoperative of it, such as in a situation of transport.

Claims (4)

1. Olive picking shovel, which being of the type that incorporates a determining body of a substantially prismatic-rectangular receptacle, of great capacity, which with the collaboration of lifting arms is capable of unloading on an agricultural trailer, is characterized because said body is associated with a tray of width coinciding with that of the body and with any appropriate surface dimension, a tray that is subsequently closed with the body's own front wall and whose lateral containment partitions extend backwards in parallel arms that are articulated to the posterior and middle area of the base body, so that said tray is capable of constituting a prolongation of the bottom of the body, resting on the ground, for the collection of olives by sweeping, and tilting upwards until facing the mouth of the body, for gravity discharge within the receptacle defined by this and last. 2. Olive picking blade according to claim 1, characterized in that the front wall of the body is curved-convex, specifically cylindrical, with an axis of curvature coinciding with the axis of tilting of the tray, so that the rear edge of the latter, During its tilting, it permanently maintains contact with the surface of the body. 3. Olive picking blade, according to previous claims, characterized in that the tilting movement of the tray is determined by two lateral cylinders, hydraulic or pneumatic, which extend between the lateral arms associated with the tray and the blade body itself. 4. Olive picking blade, according to previous claims, characterized in that the tray is structured by means of several sectors jointly linked to each other, which allow it to be folded in an inoperative situation, to minimize its volumetric occupation.
