Description

The proposed utility model is intended for operation in industrial aquaculture enterprises - on open water bodies (on watercraft and floating platforms) and in close proximity to them.

Known auto-feeder for fish "Reflex - 100" [1], consisting of a bunker and installed on it, through hinges, a lid. To prevent spontaneous opening of the lid (waves on the water, wind, etc.) there are hinges for hanging the locking device.

The disadvantage of this device is that the cover in the process of opening or closing has a large wind, which, when exposed to wind, can lead to a sharp slamming or transition to the extreme open position with high acceleration, which is a potential hazard to personnel.

Known auto-feeder "Reflex" 200 kg [2], consisting of a hopper and installed on it, through hinges, a lid. To prevent spontaneous opening of the lid (waves on the water, wind, etc.) there are hinges for hanging the locking device. There is a stopper to fix the cover in the open position.

The disadvantage of this device is that in the open state the cover has a large wind capacity, which, when exposed to wind, can cause the auto feeder to swing together with the floating craft on which it is installed. And when the lid is closed - to a sharp slamming with high acceleration, which poses a potential danger to personnel.

Known feed dispenser for fish [3], consisting of a hopper and a cover mounted on it. The lid has no hinges, and if it is necessary to open the hopper, the lid is completely removed.

The disadvantage of this device is that the cover is not connected in any way with the bunker and, when exposed to wind and waves on the water, can be lost when it enters the reservoir.

Known feed dispenser for fish [4], consisting of a hopper and installed on it, through hinges, a lid. To prevent spontaneous opening of the lid (sea waves, wind, etc.) there are locking devices.

The disadvantage of this device is that the cover in the process of opening or closing has a large wind, which, when exposed to wind, can lead to a sharp slamming or transition to the extreme open position with high acceleration, which is a potential hazard to personnel.

The closest known analogue is a device for distributing food to fish [5], adopted as a prototype, consisting of a bunker and installed on it, through hinges, covers. To prevent spontaneous opening of the covers (waves on the water, wind, etc.) there are locking devices.

The disadvantage of this device is that the covers in the process of opening or closing have a large wind, which, when exposed to wind, can lead to a sharp slamming or transition to the extreme open position with high acceleration, which is a potential hazard to personnel.

The technical result of the proposed device is to reduce windage in the process of opening and closing the lid, as well as the impossibility of spontaneous opening or closing of the lid.

The technical result is achieved in that the device is equipped with a hinge-lever mechanism, including two pairs of rods, one end pivotally connected to the cover, and the other end pivotally connected to the frame.

FIG. 1 shows a general view of the device with a closed lid.

FIG. 2 shows a general view of the device with the lid open.

The device consists of a hopper 1, with a cover 2 installed on it, connected to the hopper by means of a pair of rods 3, a pair of rods 4 and a frame 5.

The rods placement parameters are shown in Fig. 3. Dimensions are calculated using the following formulas:

X1 = 0.929X

Y1 = 0.2X

L1 = 0.377X

X2 = 0.018X

Y2 = 0.254X

Z2 = 0.315X

In this case, a deviation of ± 10% is allowed. At the same time, a deviation from the calculated dimensions will lead to an increase in windage during the opening and closing of the lid.

The device works as follows. When the cover 2 is lifted, the rods 3 and 4 move the cover 2 to the side, and then, according to the trajectories of the fixing points of the rods 3 and 4 on the cover 2 (see Fig. 2), the cover 2 performs a complex translational-rotational movement, bending around the hopper 1 with maintaining the minimum distance between the cover 2 and the hopper 1 (see Fig. 2). Further, under the action of gravity, the cover takes on the position of the lowest potential energy 2 'and abuts against the frame 5 from the side (see Fig. 2). In this case, the rods take the position 3 'and 4', respectively.

If it is necessary to close the lid 2, the lid rises and makes a translational rotational movement along the same path as when opening, but in the other direction.

Thus, in the process of opening / closing the lid, minimal windage is provided and the possibility of spontaneous opening and closing of the lid is excluded.
