Abstract

The harvesting device comprises a system of arms (16, 19) with articulations (15, 18), said arms being movably mounted (14a) on guides (12) which in turn are rotatably mounted (11a) on a mounting support (2, 7, 8, 9) mounted on a vehicle (Figs. 1 and 2). The harvesting device also comprises a trailer (Figs. 3 and 4), which is coupled to the mounting support for the transport of empty grain tanks and suspension of full grain tanks. The operator on the platform (22) at the free end of the arm (19) can have the parts of the device execute all movements (V, O, 11a, 14a) by means of a control element. His two hands are free for plucking, he can move (30a, 30b) the empty tanks (30) by means of the articulated arm (16, 19) and he can reach the tank (30c) to be filled.

Description

 DESCRIPTION

"Harvester

Various self-propelled or attached harvesting devices are known which essentially work according to three different systems:

1 - mobile platform with extendable work surfaces;

2 - G.e; ienkarm with self-propelled substructure;

^' 3 - Conveyor belts with joints that transport the crop to a container.

A3] these devices have the disadvantage that they can only be used in systems with specific characteristics (row spacing, tree height), that when driving through the rows they damage the plants and the fruits, that the working speed is slow to the working rhythm Worker is bound and that the empty container must be transported separately, which in turn will damage plants and crops.

The object of the invention is to create a device which is suitable for carrying out the harvesting, cutting, binding and other similar work in various types of plant in which the row spacing, the height, the crown shape and the density of the trees vary: can.

Furthermore, the invention. Device, the damage to plants and crops on a mini mun limit secure optimal penetration between the crowns and at the same conditions the Arbeitsbedin _¬ and thus optimize the performance.

This Λufijtibo is solved according to the invention by that at least one articulated arm is used, which has a working surface with the necessary switching elements for at least one operator at the free end, while at the opposite end there is a vertical lifting mechanism which, according to a vertical axis, is connected to a self-propelled or coupled vehicle assembled base frame, is pivotable. According to the invention, the empty containers are found during the preliminary

^• Move (harvest) between the rows of the system on the loading area of a trailer, which has a lower shelf on which the container to be filled is in the front position and, as soon as it is full, along longitudinal guides under the loading area.

₁ 5 ten rolls and is put down.

Be it the hanger for the empties as well as two lifting mechanisms mounted next to one another, according to the invention, do not take a significantly larger slurry. 20 th as the empties themselves or as the self-driving vehicle (tractor).

The interplay of movements in two directions, ^' which the working platform with the operator

25 allows penetration between the plants in a row and between the branches of the plant itself, so that optimal working conditions are possible for harvesting, pruning and similar work. According to the invention, the adjustment of the

30 empty containers are carried out from the loading area into the filling position by means of the lifting and swiveling mechanism of the articulated arm. The device can be equipped with a compressed air system for cutting tools and with a remote control for the vehicle.

35 be. The invention is explained in more detail with reference to an embodiment of an apparatus according to the invention, in particular for fruit harvesting, which is shown schematically in the accompanying drawings.

FIG. 2 is a plan view of the device shown in FIG. 1 with a lifting mechanism in section, according to plane II-II in FIG. 1. ':>

Fig. 3 is a side view of the hanger for the containers.

FIG. 4 is a front view of the hanger according to the section plane IV-IV shown in FIG. 3.

On the hydraulic arms of a tractor or a self-hauling or towed vehicle, a support frame 2,7,8,9 with support roller 5 with axis of rotation .6, which can serve as a compressed air container, is mounted by means of eyes 3.4. The entire support frame is vertical, movable in that the hydraulic lifting device is set in motion and lies on the floor 1 during operation of the device by means of roller 5; by means of pins 11 and brackets 10, a vertical pair of guides 12 for a carrier 14 with rollers 23, mounted on rollers 23, are pivoted by pins 15, 1 a Doppelar 16 which is pivotable by means of hydraulic cylinders (not shown). i The carrier 14 is by means of hydraulic or compressed air: cylinder, which acts on a chain running over a deflection roller 13 at the upper end of the guides 12, ver 14a. At the free end of the double arm 16

_^ is pivoted by means of pin 18, the second pivotable 18a arm 19, which in turn carries the pivotable 21a 21 working platform 22 at the opposite end. Rigid or flexible transmission elements 17, 20 with the corresponding ic, deflection levers or / and wheels or - sectors provide in a known manner a connection between the movement 15a of the double arm with respect to the carrier 14, and the movement 18a of the second arm, respectively. of the movement 21a of the platform 22 for the operator, on which the switching elements for the various movement elements and for the vehicle are also provided.

The mechanism that controls the movements 15a, 18a,

-> ₀ 21a connects such that the platform 22 is essentially horizontal, or orthogonal to the guides will hold £ 12g. The platform 22 can, because of the articulated arm 16, 15 and the bearing 11, any point

-} 2,7,8,9. An angle that is greater than 90 °. Preferably, the pivoting movement 11a extends from beyond the middle driving line to over 90 ° to it. The vertical movement 14a of the carrier 14 with

; v-, the articulated arm 16, 19 causes within the circle bogense tors any point, within the maximum vertical run, can be reached - V -. It is advantageous that the different working positions can be reached in different ways, for example, before or after the perpendicular is taken over the point to be reached

- 0 - has been vertical by lifting or lowering

- V - this can be achieved so that obstacles such as branches can be skilfully avoided. Because of the range, an operator Furthermore, can the second, on an articulated arm is mounted on the same frame 11, support with "his EIGE nen." Arm in work or inzwi _^ be seen independently at different iChem Erntebehang, requires work.

The compact design of the articulated arm and the lifting mechanism make it possible to mount several devices on the same support frame and / or on the same vehicle.

The unity of the construction results from the fact that because of the single cylinder for the operation of the articulated arms 16, 19, in an extremely retracted position, an arm 19 moves in between the other arm 16 or overlaps with it laterally. The harvesting process with the device described above provides for the use of a well thought-out hanger before its function is closely related to that of the device.

The trailer according to the invention (FIGS. 3, 4) has a drawbar 24 and an optionally extendable loading area 31a for the empty containers 30, underneath this loading area, between the wheels 28, a second loading area provided with rollers, locking means and possibly a drive is provided, on which the container 30 to be filled is placed in the front position, which is removed 30a and adjusted 30b with the aid of the articulated arm described above. As soon as the container 30c is full, it is moved 30d backwards and placed on the floor 1 by means of guides 26 which can be pivoted about the pins 27a.

This hanger enables uninterrupted advance. The workers penetrate between the rows, whereby they always have the empty containers within reach and they can dispose of the full containers at any time, without further journeys for the distribution of the empties, for the adjustment of containers that are not completely filled, or their subsequent filling to do.
