[0029] The cover plate 1 is made of a plurality of square tubes of different lengths fixedly connected to a stainless steel plate, and the cover plate 1 is fixedly installed at a corresponding position on the breeding equipment for use.

[0030] In this embodiment, the screw pump 2 can continuously suck, seal and discharge the aquaculture slurry through the interaction between its own screw and the pump casing, thereby realizing effective transportation of the aquaculture slurry. The specific working principle of the screw pump 2 is well known and widely used in the prior art and will not be repeated here.

[0031] A feed port 21 is disposed in the middle of the screw pump 2 , and one outlet of the three-way solenoid valve 3 is fixedly connected to the feed port 21 of the screw pump 2 via a flange.

[0032] The inlet of the three-way solenoid valve 3 is connected to an external device for containing aquaculture slurry through a hose, which is not indicated in the figure.

[0033] In this embodiment, the three-way solenoid valve 3 can control the flow and flow direction of the aquaculture slurry. In the prior art, the specific control principle of the three-way solenoid valve 3 is well known and widely used, and will not be repeated here.

[0034] like Figure 2-4 As shown, the material storage group 4 includes a plurality of support columns 41 vertically arranged at one end of the screw pump 2, and the plurality of support columns 41 are in a square array. In this embodiment, the number of the support columns 41 is set to four, and the four support columns 41 are in a square array.

[0035] The same supporting plate 42 is fixedly mounted on the four supporting columns 41 .

[0036] A avoidance hole 420 is formed at the middle of the support plate 42 .

[0037] A plurality of ejection cylinders 43 are vertically arranged on one end surface of the support plate 42 close to the support column 41 .

[0038] In this embodiment, the number of the ejection cylinders 43 is three, the three ejection cylinders 43 are in an equilateral triangle array, and the power output ends of the three ejection cylinders 43 pass through the support plate 42 .

[0039] A plurality of weighing sensors 44 are arranged alternately on one end surface of the support plate 42 close to the support column 41 and the three ejection cylinders 43 . The number of the weighing sensors 44 is also three.

[0040] In this embodiment, the working principle of the weighing sensor 44 is well known and widely used, and will not be described in detail here.

[0041] The middle of the three weighing sensors 44 are respectively threadedly connected with studs 45 .

[0042] Three studs 45 penetrate through the support plate 42 and are connected to a storage bag assembly 408 .

[0043] The storage bag assembly 408 includes a same mounting plate 47 movably placed on an end surface of three studs 45 away from the support plate 42 .

[0044] A positioning guide sleeve 46 is fixedly mounted on one end surface of the mounting plate 47 close to the supporting plate 42 and at positions corresponding to the ejection cylinder 43 and the stud 45 respectively.

[0045] A conical surface 460 is disposed at one end of the positioning guide sleeve 46 close to the support plate 42 , and a bearing surface 461 is disposed at the small end of the conical surface 460 of the positioning guide sleeve 46 .

[0046] One end surface of the three studs 45 away from the support plate 42 is in contact with the bearing surface 461 .

[0047] When the power output ends of the three ejection cylinders 43 are extended, they respectively contact the corresponding bearing surfaces 461 of the positioning guide sleeves 46 .

[0048] A storage bag 48 is fixedly mounted on one end surface of the mounting plate 47 away from the supporting plate 42 , and the aquaculture slurry is stored in the storage bag 48 .

[0049] One end of the storage bag 48 passes through the avoidance hole 420 of the mounting plate 47 and the support plate 42 and is connected to a connecting port 50 .

[0050] The connecting port 50 is connected to another outlet of the three-way solenoid valve 3 through a hose.

[0051] The other end of the storage bag 48 is connected to a one-way valve 49 .

[0052] In the prior art, the one-way valve 49 can control the flow of fluid. The specific control principle of the one-way valve 49 is well known and will not be described in detail here.

[0053] With such a design, the mounting plate 47 drives the storage bag 48 to abut against the corresponding stud 45 through the bearing surfaces 461 of multiple positioning guide sleeves 46. The gravity of the storage bag 48 is detected by the weighing sensor 44. When the aquaculture slurry in the storage bag 48 changes, it is detected and fed back by the weighing sensor 44.

[0054] The other end of the discharge pipe 23 is connected to a feeding device of the breeding equipment, which is not indicated in the figure.

[0055] like Figure 1 As shown, the exhaust pipe group 5 includes a three-way joint 51 which is connected to two one-way valves 49 through a hose.

[0056] The other end of the three-way joint 51 is connected to an air supply pipe 52 , and the air supply pipe 52 is also fixedly mounted on the cover plate 1 .

[0057] The other end of the gas delivery pipe 52 is connected to a slag receiving device of the breeding equipment, which is not indicated in the figure.

[0058] The control ends of the screw pump 2, the three-way solenoid valve 3 and the one-way valve 49 are connected to the control system wires of the breeding equipment through wires.

[0059] The control end of the ejection cylinder 43 is communicated with the corresponding solenoid valve in the control system of the breeding equipment through an air pipe.

[0060] The specific working principle of the aquaculture equipment control system for driving the screw pump 2, the three-way solenoid valve 3, the one-way valve 49, and the ejection cylinder 43 is well known in the prior art and will not be described in detail here.

[0061] When in use, the control system of the breeding equipment controls the three-way solenoid valve 3 to open the channel connecting the external device for containing breeding slurry and the connecting port 50, and the channel connecting the three-way solenoid valve 3 to the discharge port 22 is closed. In this way, the external device for containing breeding slurry transports the breeding slurry into the storage bag 48 through the three-way solenoid valve 3 and the connecting port 50.

[0062] The control system simultaneously controls the one-way valve 49 to open, so that when the aquaculture slurry is transported into the storage bag 48 , the mixed air in the storage bag 48 is discharged through the one-way valve 49 via the exhaust pipe group 5 .

[0063] When the gas pipe 52 is connected to one end of the slag receiving device to discharge the aquaculture slurry residue, it proves that the storage bag 48 is full of aquaculture slurry, and the control system controls the three-way solenoid valve 3 to close the channel connecting the external device for storing aquaculture slurry and the connecting port 50.

[0064] Then the control system starts the screw pump 2 and controls the three-way solenoid valve 3 to open the channel connected to the feed port 21. In this way, under the self-priming effect of the screw pump 2, the aquaculture slurry in the storage bag 48 is sucked into the discharge port 22 and transported to the discharge pipe 23, and then the aquaculture slurry is transported to the feeding device.

[0065] At this time, the weighing sensor 44 detects the weight of the storage bag 48. When the reduced weight value of the storage bag 48 reaches the preset value of the weighing sensor 44, the weighing sensor 44 feeds back a signal to the control system. The control system controls the closing of the channel connecting the screw pump 2 and the three-way solenoid valve 3 to the feed port 21, and stops the discharge port 22 of the screw pump 2 from conveying the aquaculture slurry into the discharge pipe 22. In this way, the amount of aquaculture slurry put into the aquaculture equipment can be controlled to achieve quantitative and scientific aquaculture.

[0066] In order to avoid detection errors after the weighing sensor 44 is used for a long time, after the weighing sensor 44 has been used for a period of time, the control system controls to start the ejection cylinder 43, and the power output end of the ejection cylinder 43 extends out to contact the corresponding bearing surface 461 of the positioning guide sleeve 46, and then drives the mounting plate 47 to lift the storage bag 48, and then separates the storage bag 48 acting on the stud 45. At this time, the weighing sensor 44 is not subjected to gravity for zero correction. After the correction is completed, the power output end of the ejection cylinder 43 retracts, and the mounting plate 47 drives the storage bag 48 to act on the stud 45 again to carry out the cyclic feeding work.

[0067] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
