Description

one

The invention relates to the field of mechanization of agricultural production and the food industry, namely to devices for sorting fruit, vegetables and potatoes.

Notify the device for sorting fruits, consisting of feeding, measuring and dividing elements, in which the separating element, made in the form of a flap or pusher, is located above the conveyor and directs the objects into the channel corresponding to a certain fraction

one.

Such separating elements have a long response time, since in order to separate one object from another, they need to complete a full cycle consisting of working and idling strokes. This limits the productivity of the machine.

A device for sorting parts on dimensional parameters is known. OO contains a transport disk with cells for accommodating controlled parts and a single-shaft sensor made in the form of a pre-deformed flat spring with a rod and a sorting gate. During the passage of the transport disk, the controlled parts, which correspond to the size of the upper limit of the sensor, act on the rod, which presses

about

Sludge from one position to another and opens the sorting valve.

This device is intended for sorting parts by size in small tolerances, and its design does not allow sorting of fruits that are easily damaged and differ in shape and size.

A device for visual sorting of fruits using a coitrol drum 3 is known. It contains a feeding conveyor with fixed elements of a piece iodachi ilodi attached to it with a constant schag, fixed diversion channels for irnem ilodies fixed on it, a sorting drum located on its surface with the same constant schag sorting positions, having fruit pushers into the drainage channels, a command unit for visual inspection of nlodes, electromagnetic gliding with pressure elements for the transmission of command signal to the ejector and mechanism for returning the ejector to its original position.

The command unit examines the defectiveness of the fruit, supplies the sigpal to the electromagnetic mechanism, which by the pressure element drives the ejector of the sorting drum, which releases the fruit into the tapping channel.

This device is closest to the invention in its technical essence and the achieved result.

However, this device has narrow technological capabilities, since it can only sort grain sizes and shapes due to the limited size of the sorting drum positions and pushers made in the form of electromagnet rods with insufficient speed and short stroke. In addition, the device is structurally difficult and unreliable due to the presence of current collectors and a large number of electromagnets that require, to the extent, that the working area is clean.

The purpose of the invention is to expand technological capabilities and simplify the design.

This is achieved by the fact that the ejector pushers are made in the form of double-arm levers hinged at the sorting positions, on the shoulders facing the middle part of the drum which are fixed the ends of the pre-deformed flat elastic elements, the free arms of the levers are set to interact with the pressure elements of the electromagnetic mechanism, and the mechanism return ejector to its original position is made in the form of a cam disc installed with the ability to interact with the elements of the post hydrochloric supplying the input conveyor of the fruit.

FIG. 1 shows the described device, side view; in fig. 2 is a cross section along LL in FIG. i.

The device includes a feeding conveyor with elements of single-serving fruit, for example roller chain conveyor 1, sorting drum 2, command unit 3 of fruit sorting, diversion channels 4. Drum 2 consists of flanges 5 that have protrusions with a periphery equal to that of the roller conveyor, the two shoulders of the arms 6 are hinged. The ends of the previously deformed flat springs 7 are fixed on the shoulders of the levers 6 facing the middle part of the drum, while the length of the spring exceeds the distance between the points L. second seal in the trailing arm. To drive the roller conveyor 1, sprockets 8 are mounted on the same axis as the drum.

In the area of the upper branch duct, electromagnets 9 are installed on the transnorter's frame to interact their rods with the free arms of the arms 6. On the shaft parallel to the drum axis, in the lower part, there is a mechanism 10 for returning the ejectors to the initial position, made in the form of a cam disc. The disk is installed with the possibility of interaction with the rollers of the conveyor.

Fruits 11, arranged one by one between the rollers of transnorter 1, are fed through

the control zone in the zone for sorting; ibarabi 2. The fruit grading command unit 3 determines the defect of the fetus, and at the time of the passage of the marked fruit in

The zone of action of electromagnets 9 supplies them with a sigal. The electromagnets act on the rods of the free arms of the double-arm levers 6 and the springs 7 are transferred from the initial (concave) position to the convex one. Spring pushes the fruit in the branch channel. When the drum 2 is rotated, the spring, having made a working stroke, returns to its initial position with a cam disc 10, which is driven into rotation by coupling to

conveyor rollers. When passing through the control zone of a standard fetus, the command unit does not send a signal to the electromagnets 9, the spring remains in the initial position, and the fetus leaves the drum in the corresponding bypass channel.

The use of a device with ejectors of the proposed design allows sorting of fruits that differ sharply in size and shape, which will increase the annual load

devices 3-5 times.

Soil plots do not affect the performance of the entire device, since all the rubbing elements are located in the contaminated area.

The stationary installation of electromagnets outside the drum makes it possible to get rid of current collectors and reduce the size of the drum, which simplifies the design and increases the reliability of operation.
