Abstract

The invention relates to agricultural machinery, in particular fruit picking machines. The aim of the invention is to increase the efficiency of fruit collection by increasing the completeness of their picking. This goal is achieved by the fact that in the fruit cultivator containing a base with a drive located on it and a frame kinematically connected to it, on whose shaft fingers 5 of a crescent shape are mounted, a comb 6 is installed on the base, equipped with a vertical movement mechanism, fingers are mounted on a screw lines of at least two turns with the possibility of adjusting the angle of inclination in a plane perpendicular to the axis of the shaft, and the fingers are made elastic. The fingers penetrate the crown, moving simultaneously along the row, and simultaneously vibrate, stitching the fruit. 2 ill.

Description

FiM

The invention relates to agricultural machinery, in particular to fruit picking machines.

The goal is to increase the efficiency of the device.

Figure 1 shows a general view of a str., Rear view; figure 2 is a diagram of the interaction of combs and fingers.

The fruit strainer contains a base 1 on which a drive 2 and a frame 3 are mounted. A shaft 4 is kinematically connected to the drive 2.

On the shaft 4 are installed along a helical line elastic fingers 5 of a crescent shape.

The fingers 5 are mounted with the possibility of adjusting the angle of inclination in a plane perpendicular to the axis of the shaft 4. The helix, in which the fingers 5 are mounted, has at least two turns. A comb 6 is mounted on the base 1 and on the frame 3 with the possibility of vertical movement. The mechanism 7, for example, a hydraulic cylinder, carries out the vertical movement, the size of the vertical movement of the comb is 1/8 of the length of the fingers 5. A catcher 8 is installed to receive the picked fruit from the tree crown.

The vehicle is driven and steered — a moving vehicle and moved along a row of trees, Fingers 5, turning c are integrated into a cut, meeting the resistance of the branches and simultaneously shifting along the row, fingers 5 vibrate, and out of the load of branches make a complex chaotic movement, forcing

the branches of trees in contact with them in the nearby area of the fingers oscillate 5. Fruits, tearing themselves off, fall onto the catching device 8.

When using a scrubber to harvest fruit with thin branches to increase the amplitude of finger vibration, they are additionally informed of vibration due to contact with comb 6. For this, by means of mechanism 7, the comb is introduced into the contact zone with fingers 5. The size of the overlap zone of fingers 6 and comb 7 depends from the thickness of the branches and can reach 1/8 of the length of the fingers 5,

Upon contact of the fingers 5 with the comb 6, the fingers deviate from the usual trajectory in their movement, receive additional kinetic energy due to short-term engagement with the comb

and oscillate with a larger amplitude.

Formula and zobretten. A fruit strainer containing working bodies mounted on the chassis frame in the form of elastic fingers placed on a vertical shaft and a drive, and so that, in order to increase the efficiency of the device, elastic fingers are mounted on the shaft along a helical lines with the possibility of adjusting the angle of inclination relative to the axis of the shaft; moreover, a finger comb having a vertical movement mechanism is mounted on the frame.
