The invention relates to an aquatic bait feeding device based on an agricultural Internet of things, which comprises the following working procedures:

when fish in the culture pond 11 needs to be fed, the first motor 12 is powered on, the first motor 12 drives the main shaft 14 and the driven shaft to enable the sliding plate 15 to move leftwards when being powered on, the second ratchet wheel 27 cannot drive the reciprocating screw rod 26 to rotate, the oxygen inflating block 51 can work and inflate air into water when the sliding plate 15 moves leftwards, the triangular plate 30 can abut against the second limiting block 31 in the process that the sliding plate 15 moves leftwards, so that the fish can only pass through the fish passing cavity 16 from a gap between the two triangular plates 30, the sensor 61 can count the passing fish, the first filter screen 18 abuts against the first limiting block when the sliding plate 15 moves leftwards, so that the first filter screen 18 is in a vertical state, and floating objects such as dead fish floating on the water surface in the motion process of the sliding plate 15 can be intercepted by the first filter screen 18 and abut against the left side surface of the first filter screen 18.

When the sliding plate 15 moves to the right limit, the first motor 12 is powered off, the sensor 61 finishes counting work, the blocking block 50 is pushed by the first ejector rod 32 and moves leftwards, so that the water inlet 21 can circulate, at the moment, water in the culture pond 11 drives floating objects in the collecting cavity 17 to flow into the waste cavity 19 through the water inlet 21, the floating objects are retained on the second filter screen 20, then the water pump 70 is powered on to return water into the culture pond 11 through the water outlet 22, the second motor 39 is powered on at the same time, the data obtained by the first sensor 61 can control the power-on time of the second motor 39, fish materials enter the feeding hole 43 when the second motor 39 is powered on, the elliptical disc 71 is driven to rotate when the second motor 39 rotates, so that the connecting plate 47 moves leftwards and rightwards, and fish materials in the feeding hole 43 can intermittently fall into the water immersion cavity 29 through the water passage port 48 in the process, the amount of the fish material entering the soaking cavity 29 is in direct proportion to the power-on time of the second motor 39, and the fish material entering the soaking cavity 29 swells when meeting water, at the moment, the baffle 35 can prevent the fish from entering the soaking cavity 29 to eat the fish material which does not swell completely.

After the second motor 39 is powered off, the first motor 12 drives the spindle 14 to rotate reversely, when the second motor 39 is powered off, the connecting plate 47 is always positioned at the right limit position due to the elastic force of the third spring, and the material passing port 48 is positioned in the through groove 44, at the moment, the sliding plate 15 moves rightwards, at the moment, the oxygen applying block 51 stops working due to the action of the first ratchet wheel, so that the fish is prevented from being sucked into the oxygen applying hole 55 and being cut by the blade 59, after the sliding plate 15 moves rightwards for a certain distance, the blocking block 50 is reset into the water inlet 21 due to the elastic force of the second spring, at the moment, the water pump 70 stops working, at the moment, the rotation of the spindle 14 can drive the second ratchet wheel 27 through the second synchronous belt 28 and drive the reciprocating screw 26 to rotate, the reciprocating screw 26 can drive the screw block 34 and the material pushing plate 33 to periodically move leftwards and rightwards, and the material pushing plate 33 can push the fish material positioned in the soaking cavity 29 when moving leftwards, meanwhile, when the push plate 33 moves leftwards, the baffle 35 is pushed through the second ejector rod 37 and the baffle 35 is separated from the permanent magnet 36, so that fish materials pushed by the push plate 33 can enter the culture pond 11, when the sliding plate 15 moves to the right limit position, the first motor 12 is powered off, and at the moment, the push plate 33 moves leftwards and rightwards for a plurality of periods and then stays at the right limit position, then the permanent magnet 36 attracts the baffle 35 and enables the baffle 35 to be abutted against the permanent magnet 36 to complete resetting, the sliding plate 15 can scatter the fish materials entering the culture pond 11 in the process of rightward movement of the sliding plate 15 so as to prevent fish from gathering and snatching, and the first filter screen 18 is in a parallel state due to the fact that the first limit block is lost in the process of rightward movement of the sliding plate 15, floating objects cannot be pushed rightwards, and due to the fact that the triangular plates 30 lose the abutting effect of the second limit block 31, gaps between the two triangular plates 30 can be enlarged, the load on the first motor 12 is reduced and the fish can move more freely to obtain fish feed.

Compared with the prior art, the invention has the following beneficial effects: the fish feeding device can detect the number of fishes in the culture pond before feeding, and can automatically determine the amount of the thrown fish material according to the number of the fishes, so that the situation that the fishes are difficult to grow due to excessive fish material or insufficient fish material is avoided;

the fish feed can be firstly expanded and then put in, so that the condition that the fish feed expands in the fish maw and props up the fish is avoided;

the invention is provided with the moisture-proof mechanism, can realize the complete separation of the thrown fish material and the fish material in the storage cavity, and avoids the storage cavity from being affected with moisture.

The invention collects the floating objects floating on the water surface in the process of counting the number of the fishes and separates the floating objects from the culture pond, and meanwhile, the invention can carry out oxygen aeration work in the process so as to ensure the water quality in the pond.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
