Description

The invention relates to the agricultural industry and can be used in the sorting of agricultural products.

The purpose of the invention is to improve the sorting accuracy.

Constructive implementation of additional elements allows creating conditions in which the quality of control of fruits is improved.

The drawing shows a diagram of a device for sorting fruits.

The device for sorting the fruits contains a loading hopper 1, a piecewise delivery mechanism 2, a fruit feeding mechanism 3 into the control zone, an analyzer 4 with a light source and an actuator 5, a fruit rotation assembly 6 in the control zone, made in the form of a drum 7, a bottom with a hole, drive (not shown), tray 8. The fruit feeding mechanism 3 has cells 9 formed by flexible endless ribbons connected by transverse plates.

A device for sorting the fruit works as follows.

From the loading bunker 1, the fetus is delivered by the mechanism 2 of the single issue to the cells of the mechanism 3 for feeding the fetus to the control zone, the bottom of which before and after the control zone is a stationary base with an opening and in the control zone the surface of the drum of the fetal rotation unit opposite to the movement of the fetus 5. After By analyzing the analyzer 4, the fruits are divided into two streams by the separation actuator 5, which is located under the fixed tray 8.

When it enters the cell9, the fruit moves progressively with speed V by the mechanism 3 feeding the fruit to the control zone, rolling along the surface of the base and occupying a stable position at the back of the cell wall 9. When in contact with the surface of the rotating drum 7, the fetus receives an additional rotation around its axes,

Thus, in the control zone of the analyzer 4, the fruit performs three types of movement: translational motion, rolling over the surface of the drum 7, rotation around its axis, obtained from interacting with the surface of the rotating drum 7.

Progressive motion of the fetus on

s.in value

D allows the analyzer 4 to view the surface of the fetus within the limits of the angle oL, determined by the scattering indicator of the surface of the investigated fruit (T) - the diameter of the fruit).

To view the entire surface of the fetus once, at the same time, At, the fetus rotates due to two last movements by an angle, for two times - by .4JT-di, and for three times - by b -ll-ct. Due to rolling on the surface of the drum 7 while moving the fruit

by the value of sin j Б „, it rotates at an angle with.

From what has been said, as a result of the interaction with the drum 5, the fruit 2 must additionally turn through an angle

If you compare the movement of the drum 7 with the movement of the conveyor rollers at the same speed of movement of the fetus

50 mm / s and with a drum diameter of 750 mm, for a single viewing of the surface of the fetus the drum must perform 1/3 rev / s, for a double one - 1 1/3 rev / s, and for a triple one - 2

In contrast to the known device, the fruit in the proposed device is in contact with only one permanently and at a constant speed the rotating-MiMCH element and is constantly located at the back wall of the cell. In addition, when hit on the drum, the fetus already has a rotational movement due to rolling over the surface A,

Claims (1)

These factors ensure a stable position of the fetus during its finding in the control zone and allow it to bring its rotational speed to a value that provides multiple control of the surface of the analyzed fetus. As a result, the proposed device provides higher reliability of control results. Invention Formula A device for sorting fruits, including a loading bunker, fur. Editor P.
