The invention relates to fish farming and can be used in fish farmers when feeding fish.

The purpose of the invention is to increase reliability and eliminate crushing of feed.

The proposed device allows feeding of various fish species (carp, salmon, etc.), using both granular and pasty feeds, and feeding is carried out both by scattering pellets over a large area, and directly on the feeding table, This is ensured by the smooth adjustment of the stop with a shock absorber.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one.

The device consists (Fig. 1) of the hopper

1dl feed and mounted on it successively located steamer 2, dispenser 3, spreader 4, and also stops 5, consistently along the line of distribution of feed (Fig. 2). The hopper 1 is mounted for movement along this line (not shown).

The cutter 2 and the spreader 4 (Fig. 2) are mounted on a vertical axis 6 with the possibility of swinging and are equipped with levers 7 and 8 for interacting with the stops 5. The levers 7 and 8 have stops 9 and 10 interacting with the cutter 2 and the spreader 4 during the distribution of the feed . When the bunker moves in the opposite direction, the levers 7 and 8 are idling, they are equipped with springs 11 and 12 to return to their original position.

To return to the original position after the delivery of the portion of feed of the cutter itself

2 and the spreader 4 are springs 13 and 14. To limit and regulate the stroke of the shutter, there is a stop 15 fixed on it and interacting with the elastic element 16 of the bunker 1 (Fig. 3). To limit and regulate the course of the spreader, an emphasis 17 is used, fixed on the bunker 1 and equipped with a shock absorber 18.

The cutter 2 is made-shaped, with the main opening 19 for the passage of feed formed in the upper shelf, and the lower shelf has an additional opening 20 for the passage of feed displaced relative to the main one.

The spreader 4 is a scoop with vertical partitions 21.

The dispenser 3 is made in the form of a frame, the internal dimensions of which correspond to the dimensions of the outlet of the hopper 1. The dispenser 3 is equipped with a feed dose regulator 22 mounted for movement by means of a screw 23 equipped with risks 24 determining the volume change of the dispenser 3 (Fig. 3) ;

The device works as follows. Depending on the feeding technology, the required volume of the dispenser 3 is set, corresponding to a single dose.

feed, by rotating the screw 23 to the corresponding (dispensed by the volume of the frame of the dispenser 3) risks 24. At the same time, the regulator 22 moves inside the frame of the dispenser 3. Load 1 feed (preferably granulated) into the hopper. In the initial position, the Cutter 2 is in a position in which the upper opening 19 is aligned with the outlet of the hopper 1 and the opening of the dispenser 3, the opening of the latter is blocked from below by the lower shelf of the isolator 2, which ensures filling the dispenser volume with feed. When this spreader 4 feed is located under the lower hole 20.

When moving the hopper 1 along the distribution line of the feed (not shown) levers

0 7 and 8 collide with stops 5, the number of which is determined by the number of feeding places and the density of fish landing. They rotate about axis 6, carried away by stops 9 and 10, levers 25 and 26, realizing the movement of the associated cutter 2 and the spreader 4, until the lower opening 20 of the cutter 2 coincides with the opening of the metering device 3. The amount of movement of the selector 2 must be at least double the width of the holes 19 and 20, i.e. double shear of the dispenser frame 3 so that the upper shelf of the cutter 2 completely blocks the outlet of the hopper 1 before the lower hole 20 begins to align with the opening of the dispenser frame 3. As the opening 20 coincides with the dispenser frame 3, the feed from

5 of the latter is poured into the scoop of the spreader 4 of the feed, which moves synchronously with the cutter 2. With the further movement of the bunker 1, the levers 7 and 8 descend from the stop 5, and under the action of the springs 13 and 14 the shutter 2 and the spreader 4 return to their original position . At the same time, the movement of the trimmer 2 is limited to the stop 15, which through the elastic element 16 acts with a blow to the wall of the bunker 1, thereby helping to fill the dose frame of the 5th torus 3 with food, excluding feed formation in the hopper 1. The feed spreader 4 does not have resistance to movement, since is pumped independently of the cutter 2 under the action of the spring 14, with acceleration it moves to the adjustable stop 17. At the same time

0 distributed between the partitions 21 of the scoop, receiving acceleration, by inertia makes further movement, evenly distributed over the water surface, forming a feeding spot, the value of which depends on the amount of feed and the speed of movement of the spreader 4. by adjusting the thrust of the spring 14 by changing its length by

adjusting screw (not shown). The baffles 21 contribute to the uniform distribution of the feed in the spreader scoop (they prevent the feed from moving to the scoop angle during its accelerated movement) and serve as guides for the feed movement from the scoop at the moment of scatter.

If it is necessary to distribute the feed without scattering it over the water surface (for example, when carp is covered from the feed table) it is necessary to set the adjustable stop 17 to a position where the scoop of the spreader 4 feed distribution is shifted relative to the lower opening 20 of the shutter 2. At the same time, the lever 8 leaves the areas of accessibility of the stop 5, and the feed, when moving the cutter 2 through the opening 20, directly pours into the water (for example, on the feeding table). When the bunker 1 moves in the opposite direction, the feed will not be distributed, since the levers 7 and 8, hitting the stops 5, turn on axis 6 in the opposite direction from the working side. In this case, the stops 9 and 10 round the ends of the trimmer 2 and the spreader 4. The levers 7 and 8 return to their original position with the help of springs 11 and 12. The total time of movement of the bunker 1 in the forward and reverse directions determines the feeding cycle.

The use of the proposed device will improve the reliability of its operation due to the presence of an independent suspension of the feed spreading mechanism, which ensures its free movement with a given acceleration, to exclude crushing of the feed, since the spread of the feed is due to its inertial movement

at the moment the scoop stops with food, i.e. the feed is not mechanically affected causing abrasion. The presence of vertical partitions in the scoop contributes to a uniform dispersion of feed over the water surface, which ensures its better palatability. The elimination of crushing feed and its even spread ensure a reduction in feed coefficient due to a decrease in feed loss.
