SU351505A1 - DEVICE FOR COLLECTING FRUIT - Google Patents

Description

The invention relates to machines for mechanized harvesting of fruits, mainly from shaped, for example, palmet plants.

Various machines for harvesting fruits are known, including a frame, finger shields embedded in treetops, a vibrator, catchers, and outboard transporters. The shaking tool of these machines are horizontal fingers mounted on vibrating shields. However, the fruits, penetrating through a layer of fingers and branches, receive significant damage.

The purpose of the invention is to reduce damage to the separated fruits. This is achieved by the fact that the fingers mounted on the vibrating shields on the face, have a comb-like surface along the length of both sides in the plane of vibration. The shields move on the frame of the device to the center of a row of trees and the fingers come into contact with the branches. Since the combed surface of the fingers is made of elastic material, it does not interfere with their introduction and does not damage the crown elements, and when the fruits are exposed to the ridges of the comb surface, they fold down, and the fruits, having passed all the fingers fingers, fall with little kinetic energy on the catchers and

FIG. 1 shows the described device, a general view; in fig. 2- Rus with fingers.

The device for collecting fruits is mounted on the tractor and includes a frame / spanning tree, supported on the support wheel 2 and hinge 3. On the frame / on both sides there are guide rails 4, in which the moving frames 5 with side vertical shields 6 are moved, with catchers 7 and outboard conveyors 8. The moving frames 5 are moved by hydraulic cylinders I, which are connected to frame 7 on one side and moving frame 5 sliders on the other.

On the side vertical boards 6, the fingers 10 are secured in a staggered manner, in which the working surface is made in the form of combs with elastic protrusions 11. The vibration of the side vertical boards 6 with the fingers 10 is provided by a hydraulic cylinder 9 with a distributor 12.

Fruit harvesting by the device is carried out as follows. The unit moves along a number of trees and stops against each of them. The tractor driver uses the hydraulic cylinder 9 to move the side vertical shields 6 with the fingers 10 to the axis of the row, while the fingers 10 are inserted into the crown, dividing it into a number of horizontal sections. The elastic protrusions 11 in the zone of contact of the fingers 10 with the branches are partially deformed and tightly cover them. In the space free from the branches, they occupy the initial position and close, forming catching surfaces. After inserting the fingers 10 into the crown, the hydraulic cylinder 9 and the distributor 12 vibrate them. Due to the oscillation of the branches, the fruits are separated and fall onto the corresponding Rus catching surfaces formed by the fingers 10 with elastic protrusions 11. Falling into the joint zone of the elastic protrusions 11, the fruits under their own weight bend them and fall on the lower Rus, and then on the catchers 7 and

outboard conveyors 8, which take them to the container.

The small distance between the rus protects the fruit from damage.
