Object of the invention

s 10

The present invention relates to a self-propelled device for the collection of fruits such as olives, nuts and the like, in particular for the collection of olives, of the type comprising a vibrating element to cause the fruit to fall, a receiving element for collection thereof and a transport element to move the collected fruit to a suitable storage container, arranged these elements, vibrator, receiver and conveyor, correspondingly coupled in a self-propelled tractor element and remote control. Thus, the self-propelled device for harvesting fruits of the present invention is not constituted from a receiving element coupled to a tractor vehicle, but the receiver is the self-propelled device itself.

Background of the invention

20 25

Various types of fruit picking devices based on vibrating and picking devices, well separated or operating together, are known. In the first case, the vibrating device causes a vibration of the branches of the tree in question to cause the fruit to fall on canvases arranged on the ground and it is manually collected from them. In the case of the collecting device, it normally takes the form of an inverted umbrella and is placed around the tree in order to collect the fruits that are manually dropped. In the case of the operation of both devices together, the vibrating device drops the fruit which, in turn, is collected in the collecting device. Usually, the vibrating device is coupled to the tree by means of jaws arranged in tractor vehicles and the collecting device is also coupled to the tree, collecting the fruit and directing it, by gravity, towards the apex of the cone that forms the umbrella

inverted, subsequently unloading the fruit through a hopper towards a

container.

For example, in ES 2 065 213, "Fruit harvester

detached by vibration ", a fruit harvesting machine is described

s

detached by vibration that consists of two machines that can go

mounted on the same or different tractor; in this second case they can

Work in a coordinated or independent way. The machine that causes the

Fruit shedding is a multidirectional mass vibrator

eccentric, which grabs the trunk or branches of the trees using the clamp

10

its front end and subject them to vibration. All movements for

place the machine in the proper position and the vibration is operated with a

hydraulic circuit whose oil tank is at the rear of the tractor. The

machine that collects the downed fruits consists of a set of canvases

mounted in what is called "inverted umbrella", which extends under the

fifteen

Treetop The fruits collected at the bottom of the umbrella can be

stored in a warehouse where they arrive aspirated by a pipe and a

cyclone. The equipment may also be devoid of the suction system; in

such case, the vibrator-umbrella set can be raised to unload the

fruits through a trapdoor that opens at the bottom of the umbrella.

ES 2 200 658, "Olive harvesting machine", comprises a

small tractor vehicle that supports a folding double fan structure,

so that in the deployed position each fan receives the fruits that

they fall from the tree through the use of pneumatic vibrating rods that

they feed a compressed air equipment incorporated into the tractor vehicle. The

25

fans include openings as far as the olives reach by

glide. In turn, faced with these openings there are some bases

inclined, at whose lower edges boxes or drawers are placed to

Collect the fruits. The bases are formed by rods, through whose

spaces pass the leaves and other waste falling to the ground.

ES 2 027 101, "Vibrating machine for fruit collection", describes

   a machine shaped like an inverted umbrella, mounted on a chassis

of two equal parts attached to each tractor blade, by appropriate means. In the chassis are mounted the tractor rods that open laterally in two halves, between the rods there is a fabric that opens in the form of a fan, providing the set of one or more vibrators and the chassis of a

s gate at its base to be emptied.

Summary of the invention

The self-propelled device for the collection of fruits of the present invention, especially for the collection of olives, is of the type comprising a vibrating element to cause the fruit to fall, an element

10 receiver for the collection of the same and a transport element to move the collected fruit to a suitable storage container, where

• the vibrating element consists of a clamp-like head with pressure means to hug the tree trunk,

• the receiving element takes the form of an inverted umbrella for the collection of the fruit and

• the fruit transport element moves the collected fruit to a storage container,

these vibrator, receiver and conveyor elements being arranged correspondingly coupled to a self-propelled and control tractor element

20 remote.

More particularly, the aforementioned vibrator, receiver and conveyor elements are arranged in a self-propelled tractor or vehicle element and operated by radio control. This vehicle consists of a "U" frame with four small floating wheels

25 diameter or with a tractor unit for movement. In its central section it is provided with a frame, while in the lateral sections the inverted collection umbrella rods and the fruit transport device are arranged from the umbrella to the storage receptacle. Said vehicle further comprises a crossbar in the upper position with respect to the section

center in which the vibrating element is installed, consisting of a head

as a clamp with pressure means to hug the tree trunk, which

it has turning means on a vertical axis arranged at the end of a

longitudinal arm, whose other end is arranged on a means of

transverse translation based on an endless chain, while the element of

fruit transport consists of endless conveyor belts

arranged horizontally and along the inner part of each side of the

frame and that continue in two sections of endless conveyor belts

which is constituted by a drawer, optionally folding bottom, hung from

two telescopic and tilting stringers on the frame on the sides of the

framework of its central section and that constitute the evacuation device of the

The present invention does not need to be coupled to a tractor or any vehicle and

allows to improve safety, mobility and visibility. In operation, the

device of the present invention is directed remotely towards the tree

objective and is positioned so that it is inside the square formed

by the "U" shaped frame of the tractor element. The tractor element is

equipped with leveling means to adapt to the inclination of the ground,

thus allowing to work on sloping terrain up to approximately 18 ° and

save slopes up to 40 °. Its low center of gravity decreases

considerably the risk that the device will tip over. In addition, the control

remote from it allows the operator to work from the ground and away from the

device, eliminating the risk of accidents and allowing visual control of the

area surrounding the tree where you are working.

Therefore, the self-propelled device for harvesting fruits from the
