(5) DEVICE FOR SORTING AND OVERLOADING LIVE FISH

one

The invention relates to the fishing industry, in particular to the field of fishing pond ponds, which grow fish, and can be used to sort and reload live fish.

A device for sorting and reloading live fish when fishing pond ponds is known, including flat sorting walls radially fixed on the hollow axis, connected along the periphery of the rims, the floor axis being connected to the fishing chamber 1.

However, when using this device, the fish rolls along flat partitions to the periphery and the whole mass is then dropped to the center, which prevents the fish from orienting in the device and sorted by size through the sorting partitions.

The closest to the proposed technical essence is

device for sorting and reloading live fish, including buckets, radially mounted on a hollow axis with a window for fish passage, the bottom of each of which is a sorting surface of a curvilinear shape, and a drive. The device is installed in the tank for the flow of the water-feeding mixture, which is supplied periodically, therefore the device operates cycl1 personally, aa one turn of the buckets to sort the fish,. Received in eMKodTb G2.

The aim of the invention is to provide continuous sorting and reloading of fish and thereby increasing productivity.

To achieve this goal, a device that includes buckets radially mounted on a hollow axis with a window for fish passage, the bottom of each of which is the screening surface of a curvilinear shape we and the drive, each bucket is provided with an additional screening surface fixed in parallel to the main screening surface x mounted guide trays tilted in opposite directions, and the axis is connected to the drive and has additional windows for the passage of fish and made at its ends of the blue Consistent expansion, the windows formed in the conical expansion x axis under the outlet portions of the guide trays. In the drawings of FIG. 1 shows the proposed device, side view; in fig. 2 is a view A of FIG. 1 with a section along BB, in FIG. 3 is a view of B in FIG. 1 in FIG. - section CC in FIG. 3. A device for sorting and reloading live fish includes buckets consisting of side perforated walls 1 and two sorting surfaces 2 and 3 of curvilinear shape, respectively forming the upper and lower bottoms of the bucket, while the sorting surface 2 is made of parallel rod elements k. The buckets are fixed on the hollow axis 5 and on the outer rims 6, which are connected to the axis 5 by the spokes 7 and between each other by hard links 8. On the sorting surfaces 2 and 3 in the central part of the device there are mounted guide trays 9 located with a slope opposite sides. Axis 5 has conical extensions 10 with ends 11 for the arrival of fish at the ends, located under the outlet sections of the guiding trays 9. The ends of axis 5 are pivotally connected to supports 12, and axis 5 itself is connected with an electromotor 15 via a gearbox 1 To collect the sorted fish on both sides of the axis 5. Install containers 16 in the mouths 17. The device is placed in the discharge channel 18, in which the fish from the pond rolls in a stream. At the installation site of the device in channel 18, the bottom profile is made along the arc of the circumference of the rim 6. The main channel 18 is connected to the outlets 17 by water 19, which have oi-grids at the inlet. Bottom 17 has a water outlet 20 through which fish can be released directly into the reservoir (after determining the mass, sorting and piece quantity). Catching fish, its sorting and reloading using the proposed device is as follows. After the beginning of the descent of water from the pond through the channel 18, the fish enters the zone of action of the bucket device. At the same time, the bulk of the water (without fish) leaves through the water bodies 19. Buckets, rotating on axis 5, capture the fish with water and with further rotation filter the fish. At the same time, the fish, hitting the bucket, strenuously looks for an exit and tends to pass through the rod elements k of the upper bottom of the bucket formed by the sorting surface 2. The rotation speed of the bucket is about 1 rpm, which allows the main mass of fish in the bucket to orient bar element l and try to go through them. Through the sorting surface 2, only fish of a fixed size (according to the thickness of the fish body) passes, i.e., the fish at the initial moment are themselves sorted by size. The fish that passes through the sorting surface 2 - small fish gathers in the space between the upper and lower bottoms of the bucket, and the fish that does not pass - large fish remains above the sorting surface 2. When the bucket continues to turn and leave it from the water, sorting continues already under the influence of its own weight of each individual. During this period, the catch of caught fish begins on the bottom of the bucket down to the guide trays 9. The fish that hit the guide trays 9. Then rolls along them through the windows 11 of the cone-shaped extensions 10 of axis 5 into containers 16. The large fish that remain in the bucket the sorting surface 2 rolls to the right, and the small fish that passes through this surface rolls to the left (into the left container. This is ensured by different directions of inclination of the guide trays 9. The sorting surface 3 and the side walls 1 of the bucket are perforated Water and small fish easily pass through them and this reduces the effort to rotate the buckets of the device. Fish sorted into containers 16 is weighed and reloaded from container 16 into live fish transport. process is not interrupted. Knowing the average mass of an individual of sorted size groups and the total mass in a container, the single quantity is determined with a certain allowable error. Containers or fish pumps (their nozzles) can be installed in order to create a continuous operation in the tank 17. containers with the folding bottom. The proposed device can be used in fish farms for growing and reproducing fish. Using the device provides an economic effect of about 200 thousand rubles. in year. An invention of a device for sorting and reloading live fish, including buckets, radially hardened on a hollow axis with a WINDOW for the passage of fish, the bottom of each of which is a curved shape sorting surface, and an actuator, characterized in that, in order to ensure continuous sorting and overloading the fish and thus increasing productivity; each bucket is provided with an additional sorting surface fixed parallel to the main one; guide trays are mounted on the sorting surfaces; Sloping in opposite directions, the floor is connected to the drive and has additional windows for the passage of fish and cone-shaped expansions made at its ends, while the windows are formed in cone-like extensions of the axis below the output sections of the guide trays.
