Abstract

A device for sorting fish, consisting of a frame, rollers installed on it, a drive of rollers, an adjusting device, characterized in that the adjusting device is made in the form of a crank mechanism, the connecting rods being movably connected to the lower ends of the rollers to ensure the movement of the lower ends of the rollers in a vertical staggered planes.

Description

The proposed utility model is designed for sorting fish and can be used in food processing industry.

Known conveyor sorting device [1], containing many adjacent adjacent to each other endless conveyor belts. The distance dividing adjacent conveyor belts is greater at the discharge end than at the loading end of said belts. Each conveyor belt has a profile with inclined sides, so that between the adjacent conveyor belts of each pair a V-shaped sorting channel with continuous inclined sides is formed. Each side is located at an angle relative to the axis of the conveyor belt, the value of which lies in the range of the order of 70-85 ° to ensure a stable position of the sorted object in each channel. Each conveyor belt comprises a plurality of articulated sections forming said continuous inclined sides. Each articulated section is made with an open opening on the ridge between the inclined sides.

The device has a complex structure, which entails less reliability, as well as an increase in cost.

A device for sorting fish [2] is known, consisting of a frame, rollers installed on it, the distance between the rollers at the beginning where the roller drive is installed remains constant, and at the end it is changed using the adjustment bar. Fish is fed to the receiving surface with guides that contribute to a more uniform supply of fish to the plane of the rollers. The plane formed by the rollers is bounded by the sides. Beneath the rollers, transverse belt conveyors are installed for different sizes of fish with inclined surfaces guiding the fish falling between the rollers onto the transverse belt conveyors, which subsequently unload it into containers. At the end of the rollers there is a tapering inclined plane with sides for collecting large fish in the container that have not been sorted on the rollers.

However, manual adjustment of the gap between the rollers complicates the operation of the device and requires additional time.

The closest of the known analogues is a device for sorting fish [3], which is accepted as a prototype. Sorting of fish consists of a frame, rollers mounted on it, the axes of which lie in the same plane, and the distance between the rollers at the beginning, where the roller drive is installed, remains constant, and at the end it is changed using an adjusting device, thereby ensuring a uniform change in arithmetic progression of the distance between the rollers in the plane.

Fish is fed to the upper inclined surface with diverging fan guides, which contribute to a more uniform supply of fish to the plane of the rollers. The plane formed by the rollers is bounded by the sides. At the bottom, under the rollers, transverse belt conveyors are installed for different sizes of fish with inclined surfaces. At the end of the rollers there is a tapering inclined plane with sides for collecting large fish that have not been sorted on rollers in a container.

The use of an integral kinematic drive in an adjusting device complicates its manufacture and carrying out repair and adjustment work, and also increases the transverse dimension of the sorting assembly.

The technical result of the proposed device for sorting is to reduce the size, simplify the design of the adjusting device and, as a result, reduce the complexity of its manufacture and maintenance.

The technical result is achieved by the fact that the adjusting device is made in the form of a crank mechanism, the connecting rods being movably connected to the lower ends of the rollers to ensure the movement of the lower ends of the rollers in a vertical plane in a checkerboard pattern.

In FIG. 1 shows a general view of a side sorting apparatus.

In FIG. 2 shows a top view of a sorting device.

In FIG. 3 shows the initial position of the rollers with a minimum gap between them.

In FIG. 4 shows the extreme position of the rollers with a maximum gap between them.

The sorting device consists of a frame assembled from racks 1, 2, profiles 3 connecting them, a drive platform 4 and restrictive sidewalls 5 mounted on a frame of rollers 6, a drive of rollers 7 installed on the drive platform 4. Under the rollers 6 are inclined plates 8. Below the plates 8 are belt conveyors 9, a conveyor drive 10 with a shaft 11, mounted on the frame. A container for the material to be sorted is installed under each conveyor 12. A tray 13 is installed at the end of the rollers 6, and a container for material that has not been sorted 14 is installed below it. from the crank 16 mounted on the frame to which the connecting rods 17 are attached at one end, and the other ends of the connecting rods 17 are movably connected to the rollers 6.

A device for sorting fish works as follows. The material is fed to the rollers 6, which are installed at an angle to the horizon and rotate by means of the drive of the rollers 7, due to this, the fish moves along and falls between them as it moves. Rollers 6 rotate in one direction in order to avoid pinching of the sorted material. The shift of the mass of the sorted material in the direction perpendicular to the axes of the rollers 6 does not occur, since their diameters are selected taking into account the dimensions of the sorted material. Under the rollers with movable axles 6 there are inclined plates 8 guiding the material that has been sorted onto conveyor belts 9, which subsequently unload it into containers for sorted material 12. Belt conveyors 9 are driven by a conveyor drive 10 using a shaft 11. Material that failed to sort, slides at the end of rollers 6 into the tray 13, and from there the container for material not undergoing sorting 14 installed under it. The distance between the lower ends of the rollers 6 is set using an adjusting device 15, turning crank 16, drives the connecting rods 17 that move the lower ends of the rollers 6 in a plane perpendicular to the axes of rotation of rollers 6, which rollers 6 are positioned in a staggered configuration.
