Description

one

The invention relates to agriculture, namely, sericulture, and may find application in pedigree sericulture stations and in cutting factories, occupied by the production of pedigree and industrial grains of silkworm.

Sorting cocoons by diameter is one of the most important operations in preparing them for grenage.

It is known that medium sized cocoons are of the highest quality with high technological properties. That is why, when sifting on silt, at the power plants and nostry stations, cocoons of average diameter are selected, and cocoons with a diameter of more and less than average are rejected.

A device for calibrating tuber crops is known, consisting of a row of fan-arranged and consumption of endless straps on which potatoes are moving. When the belts diverge, the tubers, depending on their size, fall between remy. In this case, the division of tubers by size occurs.

It is also known to have a device for sorting potatoes, consisting of a series of veneered and divergent endless belts equipped with a stirrer.

However, lime calibrators for potatoes are not suitable for sorting tubers having an oval-oblong shape. Therefore, these devices calibrate andolodovato objects produced poor quality.

The purpose of the invention is to improve the productivity and calibration quality of cocoi.

This is achieved by the device having a siabzhen orientation unit of cocoons made of two cone-shaped disks placed on both sides of each pair of fan-shaped belts, with guide pins installed for orientation cocoons and one of the disks of the orientation mechanics unit fixed in the direction of movement on the shaft hard, and the other is set loosely.

FIG. I schematically depicts the proposed device, side view; FIG. 2 shows a view of an arrow A in FIG. 1 (devices with orientation unit and gauge mechanism).

The device contains three independent working bodies: a feeding mechanism, an orientation unit, a calibration mechanism, and an irivod.

The feeding mechanism includes a bunker 1, an elevator 2 with a belt 3 and several buckets 4 that are irikreilennyh to it and a pitched tray 5. The dimensions of the bucket are designed so that it only stays in place

one cocoon. At the top of the bunker, at a certain angle, there is a resetter 6, which throws the extra cocoon back into the bunker. The orientation node is made up of several parallel-parallel sections, each of which consists of two cone-shaped disks 7 and 8, which carry out the transortisation of the cocoons with their simultaneous orientation. One of the disks is fixed on a 9 liter shaft rigidly, and the other disk is mounted loosely, which is necessary for rotation of one of the disks at a slower speed, this contributes to the fast rotation of the cocoons that are mounted across the belt. For the final fixation of the cocoons, the figured guides 10 and 11 are mounted strictly along the length of the belts.

The calibration mechanism is designed to calibrate cocoons in diameter. It contains fan-shaped tensioned on the pulleys 12 and 13 of the driving shafts 9 and 14, the pulley 15 of the bypass shaft 16 and the pulleys 17 of the tensioning device, rubber-coated round belts 18 and a multi-compartment chamber 19 for collecting the calibrated cocoi.

The device works in the following way.

Kokoi cleaned off cotton wool is loaded into the feed mechanism bunker 1, where it is caught by the buckets 4 of the continuously turning-in elevator 2. If more than one cocoon falls into the bucket, the excess is removed by the diverter 6. Moving along the ramp trap 5, the cocoi fall into the gap between the discs 6. n 8, which transport and lay their belts 18, and if the cocoids fall across the gap between the disks (see Fig. 2, position I), due to the difference in the speed of the disks, they rotate in length (see Fig. 2, position ii). If the cocoons are lying across the straps 18 across (see Fig. 2, the position

Iii), when moving, interacting with the figured guides 10 and 11, rotated to the required position (see Fig. 2, position IV).

Next, on the surface of the belts 18, a successive separation of the cocoons but the diameter into fractions occurs: first, a fine fraction is released, then a subsequent fraction, which falls into chamber 19 for the calibrated cocoons.

The calibration mechanism operates from drive shafts 9 and 14 and bypass shaft 16, on which pulleys 12 and 13 are mounted, and tensioning of fan-shaped belts 18 is carried out by means of pulleys 15 and 17.

According to the data of the wittel, the use of a device for calibrating cocoons increases labor productivity by 4 times and significantly improves the accuracy and quality of the separation of cocoons.
