DESCRIPTION

Fruit harvesting machine.

This utility model refers to a tree fruit harvesting machine, which includes a structure mounted on wheels, which carries a tree vibrator, a fruit peeler, as well as storage tanks.

In the application for utility model No. 200002278 of the same applicant, a tree fruit harvesting machine is described in which the structure of the machine is composed of two parallel vertical poartics that are joined at the lower end of their lateral branches by means of two racks, which run inside said branches. These frames are longitudinally separated by a distance greater than the thickness of the tree trunks, to allow their movement around them, with a frame running on each side of the tree. The aforementioned frames define fruit receiving trays that are inclined downwards towards their internal edge, where they are finished off in longitudinal channels with drive screws. On these channels the fruit collecting trays lose. One of the frames is fitted, above the fruit collecting tray, with longitudinal tracks along which a vibrator can move, the jaws of which are located above the gap between the longitudinal frames. This separation between the frames is also traversed by a probe that is in charge of starting up the vibrator and a displacement cylinder thereof, as the machine moves with respect to the shaft to vibrate and when the shaft of the shaft impacts on the probe.

In the machine described, the shelled fruit storage tanks are included in the racks, which complicates their constitution, does not allow adequate volume tanks and their emptying takes place at a height that does not allow loading. direct on means of storage or transport.

The object of the present invention is to provide the machine with storage tanks for peeled fruits that do not alter the general structure of the machine, offer a high capacity and can be emptied easily and quickly, facilitating the dumping in means or elements of storage and / or transport.

According to the present invention, the machine has at the rear, immediately behind each frame, a storage hopper. After this hopper, the peeler is arranged on the corresponding side, which empties into the hopper. Below the hopper, the longitudinal channel and drive spindle are extended, until it reaches and empties into the peeler on the same side.

With the aforementioned constitution, the structure of the machine is not altered or interfered with, since the peeled fruit storage hoppers are located next to it, being only necessary to extend the longitudinal channel and drive spindle below these hoppers.

To facilitate the emptying of the storage hoppers, these are mounted on a horizontal tilting axis, parallel to the longitudinal axis of the structure, with the opening or emptying mouth of the hopper located above said axis.

The tipping of the storage hoppers is carried out by hydraulic actuating cylinders.

All the characteristics set forth can be better understood with the following description, made with reference to the attached drawings, in which a non-limiting embodiment is shown.

In the drawings:

Figure 1 is a front elevation of the machine.

Figure 2 is a front perspective of the machine.

Figure 3 is a rear perspective of the machine, with the hoppers in the loading position.

Figure 4 is a partial rear perspective of the machine, with the hoppers in the unloading position.

The machine shown in the drawings includes a structure that is composed of two parallel vertical portics, referenced with numbers 1 and 2, which are joined, at the lower end of their lateral branches, by separate frames that are generally referenced with the numbers 3 and 4. The machine has lower support wheels 5 for its movement.

The frames 3 and 4 run inside the lateral branches of the porticoes 1 and 2, in an inclined position, descending towards the center of the machine, being closed at the top by continuous surfaces 6 that define fruit collecting trays. Each frame 3 and 4 includes, below the lower edge of the trays 6, respective channels 7 through the interior of which drive spindles 8 run.

Structures 3 and 4 are internally separated from each other by a distance slightly greater than that of the bulk of the trees to vibrate. This separation is closed by a gabled roof 9, made up of flexible bands that protrude from the inner edge of the channels 7.

One of the frames, referenced with number 4 in the example described, has mounted, above the tray 6, a vibrator 10 that is mounted on guides 11 on which it can move along a certain length.

With the aforementioned constitution, the machine moves embracing the shaft between the channels 7, this separation being closed by the flexible cover 9. Between structures 3 and 4 there is a probe, not represented in the drawings, which when in contact with the trunk of the shaft activates the vibrator 10 and a hydraulic cylinder, not shown, responsible for moving the vibrator in a longitudinal direction. The displacement speed of the vibrator is a function of the displacement of the machine and the length of the guides 11, so that when the vibrator 10 finishes its displacement, the jaws of the same open, releasing the trunk of the tree, to be able to continue the machine with its movement to a next tree. The release operation will have a specific time.

ES 1 047 707 U ned that will always depend on the type of shaft to vibrate and that is controlled by an adjustable timer, in charge of placing the vibrator 10 in the inactive position and returning it to the initial position, in the guides 11.

The machine also includes a cockpit 12 located in its front part, and side locks 13 located above the frames.

3y4.

According to the present invention, the machine includes at its rear and below each of the frames 3 and 4, a storage hopper 14, below which the channels 7 and drive spindles 8 extend. A continuation of these hoppers are arranged peelers 15, of known constitution.

The channels 7 with the corresponding screws 8 lead to the peelers 15, which in turn lead to the hoppers 14.

As can best be seen in Figures 3 and 4, the hoppers 14 are mounted through tilt shafts 16 and are related to drive cylinders 17. Above the hinge shafts 16 the hoppers have an opening or emptying mouth. 18. On the axis 16 the hoppers 14 can tilt between a storage position, represented in figure 4, in which the emptying mouth 18 is located above the tilt axis 16, and an emptying position, shown in figure 4 , in which they occupy an inverted position, the mouth 18 being located below the axis 16. The movement of the hoppers from one position to another is achieved by means of the cylinders 17.

With the aforementioned constitution, the machine has, behind each structure 3 and 4, a deposit of considerable capacity, without affecting the structure or general constitution of the machine.

On the other hand, the emptying of the tanks or hoppers 14 is achieved with the machine's own means, by means of the cylinders 17, by placing the hoppers in an inverted position, also leaving the emptying mouth 18 in this position at a height enough for the fruits to be collected directly by containers or containers or by trailers or other transport vehicles.
