A device according to claim 1, characterized in that the guides of the U-shaped elements are made in the form of plates fixed in a flat (L elements from their outer side.

Description

P

The invention relates to devices for sorting objects according to size, namely for sorting agricultural products during their mass processing.

A device for calibrating vegetables is known, comprising a gauge sheet formed by bar elements and diverting conveyors G11.

However, this device has low productivity — and low calibration accuracy.

A device for sorting fruits and vegetables is also known, comprising a chain conveyor with formed sorting cloth with transverse straight elements with levers and rollers dp interacting with copying guides.

The disadvantages of the known device are low productivity and high fruitfulness of fruit.

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

The delivered chain is achieved by the fact that in a device for sorting fruits and vegetables, containing a chain conveyor with transversal elements forming a sorting cloth with levers and rollers for interaction with copier guides, the sorting cloth additionally contains U-shaped elements with between the straight elements, and on the straight elements there are hinged plates with a vertical groove for entering the guides.

In addition, the guides of the U-shaped elements are made in the form of plates, reinforced in the plane of the elements from their outer side.

At 4mg. 1 shows the proposed device, front view in FIG. 2 same, the view of cepxyi in fig. 3 shows the node J in FIG. 1i in FIG. 4 shows section A-A in FIG. 3j in FIG. 5 is a section bB of FIG. 3; FIG. 6 shows a section B-B in FIG. 2

A device for calibrating fruits and vegetables contains a bed 1 with asterisks 2, 3 and 4 mounted on it, on which two closed traction chains 5 are put on and their drive 6. The calibration web is formed by transverse elements made in the form of pairs of alternating - straight elements 7 (Fig. 4 and 5), rigidly fastened with bolts 8 on the traction chains x 5, and a U-shaped element 9 with rollers 10 at the ends placed in guides 11 made with a drop in a vertical plane and mounted above the calibration canvas. The guides 11 are mounted on the frame 1 with the possibility of vertical movement by means of rods 12 attached to them, moved in sleeves 13 and fixed in them by bolts 14. U - shaped elements 9 are provided with guides 15 in the form of plates arranged in the plane of the element and interacting with vertical the groove of the plates 16 (Figures 1, 3 and 4) attached to the sleeves 17 (Fig. 4) of the straight elements 7 adjacent

with U-shaped elements 9. The device also contains a feeding conveyor 18 (Fig. 1) and receiving conveyors 19-22 for each refused fraction. Plates 15 are protected

from a cover 23 (fig. 5). The device may have a specified number of calibration zones, for example, three - D, E and E.

The device works as follows:

at once.

The flow of fruits or vegetables to be sorted comes from the conveyor belt 18. 18. to the calibration belt of the chain conveyor. The tread chains 5 move the straight elements 7, which, by means of the plates 16, interact with their vertical grooves with the guide 15 of the U-shaped elements 9, involve the last

in motion. The n-shaped elements 9, moving their rollers 10 along the direction of the nickle 11, form with a straight element 7 calibrating gap, varying in the calibration zones behind

the difference in flow is directed by a knot 11 in a vertical plane, with this, each zone achieves sorting products of desired size, transported further along the process by receiving conveyors 19-21. The most non-standard fruits or vegetables pass through all working areas, are carried to the receiving conveyor 22.

Thus, the implementation of the transverse elements in the form of alternating straight and G7-shaped rods provide a high-screening

the ability of the calibration cloth improves the performance of sorting each working area. as compared with the machine of the same

The application of the proposed device-assignment and reduces damage

facilities for sorting fruits and vegetables.
