Description

1

The invention relates to agriculture, in particular to devices for sorting fruits, for example a block, by quality and size, and can be used in fruit ovary processing lines.

The purpose of the invention is to increase productivity and reduce trauma to the fruit.

Figure 1 presents a diagram of the device, side view; figure 2 is the same, top view.

The fruit sorting machine contains a transporting web 1, including the envelopes slave 2 and driving 3 chains 4 and mounted with alternation and forming cylinders 5 for the fruit cylindrical 6 and conical 7 rollers placed under the upper branch of the blade 1 mechanism 8 of rotation of cylindrical rollers 6 the lighting means 9, the fruit quality control means 10, electrically connected to the means 10, actuators 11 adapted to interact with the hinged shutters 12, and conveyors 13 for retraction fractions.

The machine is equipped with guides 14 mounted on the sides of the blade 1 to interact with the axes 15 of the tapered rollers 7, and in the loading area and quality control of the fruits the guides 14 are located above the upper branch of the blade 1, and in the area of the actuators 11 and are provided with gaps 16 for accommodating the shutters 12.

Cylindrical rollers 6 are freely mounted on axles 17 and are fixed to links of chains 4. At the same time, cylindrical roller 6 of each cell 5 has brackets 18 mounted rotatably at the ends of its axis 17, and axis 15 of conical rollers 7 is rigidly fixed other ends of the brackets 18.

The guides 14 are located relative to the chains 4 of the blade 1 at a height h, ensuring the inclination of the cell 5 for the fetus to the horizon of no more than 15 and calculated by the formula

. h b-sin (j ± 15 °).

where b is the distance between the axes of the cylindrical and tapered rollers;

J is the angle of inclination of the web to the horizon.

In the loading zone, the transporting web 1 may be configured to adjust the angle of inclination in the range of 0-60 to the horizon.

The machine can have any necessary number of parallel webs 1 and shutters 12. In FIG. depicts a variant of the machine with 3 parallel blades and two dampers, which ensures sorting by quality into three equal groups.

The machine works as follows.

The fruits to be sorted in the loading zone enter the cells 5 of the transporting web 1. continuously moving in a closed loop. In the zone

quality control of the fruit under the action of the mechanism 8, the cylindrical rollers 6 are rotated around the axis 15. In this case, the rotation is transmitted to the fetus. The fruits are analyzed by the quality control tool 10, which, in accordance with the quality information, sends a control signal to one of the actuators 11.

At the time of the approach of cell 5 with the fruit in

The location of the actuators 11 corresponding to the quality of the fetus valve 12 rotates, opening the gap 16 in the guides 14. Once the axis 17 enters the gap, the roller 7 loses support, the cell 5 starts to tilt due to gravity due to the rotation of the brackets 18 around the axis 15 and the fruit falls on one of the conveyors 13 for withdrawing the fractions.

By changing the angle of inclination of the transporting web 1 from 0 to 60, the machine can be used in various types of loading: flotation, from baths with water and dry - from a hopper or vibratory feeder,

which expands its technological capabilities.

The use of a common transporting web with movable cells, which implements the operations of loading, transporting, orienting, and sorting, doubles the productivity of the machine and reduces the damage to fruits.
