Abstract

The invention relates to the equipment of the agro-industrial complex for the automatic sorting of fruits and oats, by its surface defects. The purpose of the invention is to improve the performance of the device. New in the device is that there is an elevator with a feed and their plates between the supply bunker and the piece transfer and transfer mechanism, and the piece transfer and reception set consists of a cylindrical drum and a series of outer shells of larger diameter concentric to the cylindrical drum and connected with it by means of partitions, the openings for connecting with vacuum are made in the partitions and are connected by channels with the cavity of the inner cylinder, while the feeding plates of the Elevato and in the reception area singler angled sliding into apertures, the conveying belt of the elevator is in contact with the shells, and the elevator speed is synchronized with speed mechanism singler reception and transmission, which allows to increase the device performance. 1 3. п.

Description

The invention relates to equipment for sorting fruits and vegetables according to surface defects.

The aim of the invention is to increase productivity.

The introduction of new nodes and their design eliminates the conditions when the fruit is not captured, as well as increase the speed of movement of fruits or vegetables when sorting

FIG. 1 shows a device, side view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. 3; in fig. 5 shows a section B-B in FIG. one; in fig. 6 is a view of FIG. one.

A device for sorting fruits and vegetables contains a feed hopper 2 mounted in a common housing 1, a belt elevator 3 installed between the feed hopper 2 and the mechanism of single-piece reception and transmission, made in the form of a cylindrical drum and through holes 5 connected to a vacuum source 6, electronic devices 7 detection of surface defects, means 8 for supplying fruits or vegetables to the zone of action of electronic devices 7, ejector 9 defective fruits, tray 10 for removing defective fruits, tray 11 for removing fruit quality and the overall actuator device 12.

In the upper part of the feed hopper 2, calibrating rollers 13 are installed.

The feed plates 14 of the elevator 3 are mounted on the conveyor belt 15 at an angle of roll l to the longitudinal axis of the conveyor belt and to the openings 5.

The receiving unit of the mechanism for single-piece reception and transmission consists of a cylindrical drum 16 mounted in bearings 17 on a fixed axis 18, and a series of external shells 19 centered around the drum 16 and connected to it by partitions 20.

The holes 5 are located in the partitions 20 and are connected by channels 21 to the cavity of the drum 16, which is directly connected to the vacuum source 6.

The transmitting unit 22 of the transmission and reception mechanism 4 is located in the cavity of the cylindrical drum 16 and is made in the form of a flexible element 23 and a series of rollers 24 having guide grooves 25.

The rollers 24 are rotatably mounted around their axis on levers 26 arranged in a star-shaped manner and fixed on the fixed axis 18, and the flexible element 23 is placed in guide grooves 25 made on the surfaces of the rollers 24.

Means 8 for supplying fruits to the zone of action of electronic devices 7 is made in the form of two cylinders 27 and 28 mounted on a common axis 29 with the possibility of turning

scheni in opposite directions. The cylinder 27 of a larger diameter consists of several sectors 30, and the cylinder 28 of a smaller diameter is solid.

The transfer of fruits and vegetables into the proposed device is carried out by the vehicle 31.

The proposed device can be made mnogoruchevym and each fraction, calibrated on the rollers 13, corresponds to its own stream.

The operation of the device for sorting fruits and vegetables is carried out as follows.

Fruits or vegetables of standard size 5 are transported by vehicle 30 to the upper part of the feed bin 2 to the sizing rollers 13, where they are divided into a number of fractions, each fraction being further transported along its own stream.

Calibrated fruits enter the feed bin 2, where they are captured by the feed plates 14 of the elevator 3 and transported to the receiving zone of the fruits and vegetables of the piece-and-gear mechanism 4.

In the reception area of mechanism 4, through synchronization of the rotational speeds of elevator 3 and mechanism 4, each feed plate 14 corresponds to hole 5, in which several fruits can be taken from each feed plate 14 to holes 5 and only one fruit is caught by hole 5.

In the transfer zone of the mechanism 4, the fruits are individually separated from the holes 5 due to the fact that the flexible element 23 placed in the guide grooves of the rollers 24 closes the channels 21,

Fruits individually arrive at one of the sectors 29 of the means 8 for feeding fruits and vegetables into the zone of action of electronic devices 7, where the fruits are twisted by rotating the smaller cylinder 27 in the direction opposite to the rotation of the cylinder 26.

In the zone of operation of electronic devices 7, the fruits are controlled by electronic devices 7. When a surface defect 5 is detected, devices 7 produce a pulse, which is processed by an electronic system associated with the ejector 9.

Ejector 9 when receiving a signal from the electronic system throws defective fruits or vegetables into tray 10, and high-quality fruits or vegetables enter tray 11.
