DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The present invention provides a device for inhibiting fish pathogens based on bacteriophages. The output shaft is driven to rotate by a motor, and the output shaft drives the driven shaft to rotate through a transmission gear. The inclined blades on the output shaft and the inclined blades on the driven shaft rotate in opposite directions to mix the bacteriophage powder and the feed. During the mixing process, the rotating inclined blades continuously turn the bacteriophage powder and the feed, thereby improving the mixing effect, ensuring the quality of the bacteriophage feed, and ensuring that the bacteriophage effectively inhibits fish pathogens. Please refer to Figure 1-Figure 6 , including: a preparation tank 100 and a mixing mechanism 200.

[0026] The preparation tank 100 includes a tank body 110, a discharge pipe 120 and a discharge valve 130. The bottom of the tank body 110 is connected to the discharge pipe 120, and the discharge valve 130 is arranged on the discharge pipe 120. Among them, the tank body 110 is a circular tank with an opening at the top, and the bottom of the tank body 110 is conical. The conical base has a slope to facilitate the material to fall along the slope. The feed falls through the bottom of the tank body 110 into the discharge pipe 120 for discharge. The discharge pipe 120 is opened by controlling the discharge valve 130 to allow the feed in the tank body 110 to fall into the discharge pipe 120 for discharge.

[0027] The mixing mechanism 200 is arranged on the tank body 110, and the mixing mechanism 200 includes a top cover 210, a quantitative dispensing tube 220, a motor 230, an output shaft 240, a driven shaft 250, an inclined blade 260 and a transmission gear 270. The top cover 210 is fixed at the top opening of the tank body 110, the quantitative dispensing tube 220 is arranged at the rear side of the top cover 210, the motor 230 is arranged on the right side of the top cover 210, the output end of the motor 230 is connected to the output shaft 240 located in the tank body 110, the left side of the bottom of the top cover 210 is rotatably connected to the driven shaft 250, the output shaft 240 and the driven shaft 250 are both provided with inclined blades 260, and a transmission gear 270 meshing with each other is arranged between the output shaft 240 and the driven shaft 250; The quantitative delivery tube 220 is a transparent tube with scale marks on the outer wall and a plug structure inserted from the side at the bottom. Feed is delivered into the quantitative delivery tube 220, and the added amount is read through the scale marks. After adding, the plug is pulled out to allow the feed to leak from the bottom of the quantitative delivery tube 220 into the tank body 110. The output shaft 240 and the inclined blades 260 on the driven shaft 250 are staggered, and the top cover 210 is closed at the top opening of the tank body 110. The motor 230 drives the output shaft 240 to rotate synchronously, and the output shaft 240 drives the driven shaft 250 to rotate through the transmission gear 270. Due to the changing direction of the transmission gear 270, the output shaft 240 and the driven shaft 250 rotate in the opposite direction, thereby causing the output shaft 240 and the inclined blades 260 on the driven shaft 250 to rotate in the opposite direction.

[0028] Since the feed needs to be discharged after mixing, in order to facilitate the transportation of the feed, the discharge pipe 120 adopts an L-shaped pipe, and a discharge mechanism 300 is arranged inside the discharge pipe 120. The discharge mechanism 300 includes a discharge shaft 310, a driven bevel gear 320 and a spiral blade 330. The discharge shaft 310 is rotatably connected to the discharge pipe 120, and the driven bevel gear 320 is arranged at the outer end of the discharge shaft 310. The spiral blade 330 is arranged at one end of the discharge shaft 310 located in the discharge pipe 120. The output shaft 240 extends out of the tank body 110, and a driving bevel gear 280 meshing with the driven bevel gear 320 is arranged at the bottom of the output shaft 240; When the output shaft 240 rotates, it synchronously drives the driving bevel gear 280 to rotate. The driving bevel gear 280 drives the discharge shaft 310 to rotate through the driven bevel gear 320. The discharge shaft 310 synchronously drives the spiral blade 330 to rotate to perform spiral feeding.

[0029] Since the feed needs to be made into granules for feeding, and the directly discharged feed is in blocks, an extrusion component 400 is provided at the end of the discharge pipe 120. The extrusion component 400 includes an end cover 410 and an extrusion hole 420. The end cover 410 is screwed to the end of the discharge pipe 120, and the end cover 410 is provided with evenly distributed extrusion holes 420. When the spiral blade 330 delivers the feed, the feed is extruded through the extrusion hole 420 in the form of strips, and is broken into feed pellets.

[0030] Since the strip feed needs to be cut off, the left end of the spiral blade 330 is in contact with the inner wall of the end cover 410, and the right end of the spiral blade 330 is in contact with the right end of the discharge pipe 120. When the spiral blade 330 rotates, the left end is in contact with the inner wall of the end cover 410 and rotates, continuously cutting the strip feed on the end cover 410 to form feed particles. The spiral blade 330 scrapes off the feed remaining at the right end of the discharge pipe 120 for transportation to avoid feed deposition.

[0031] When the feed is piled up, it is difficult to fall naturally. Therefore, a feeding auxiliary component 500 is provided at the lower part of the output shaft 240. The feeding auxiliary component 500 includes a collar 510 and an arc-shaped spring piece 520. The collar 510 is fixed at the lower part of the output shaft 240. The outer wall of the collar 510 is provided with evenly distributed arc-shaped spring pieces 520. When the output shaft 240 rotates, the arc-shaped spring pieces 520 contact the discharge pipe 120. When the output shaft 240 rotates, the collar 510 is synchronously driven to rotate, so that the arc-shaped spring piece 520 continuously strikes the discharge pipe 120, and the vibration generated by the striking causes the feed to fall.

[0032] Since vibration and noise are generated during operation, evenly distributed legs are provided around the bottom of the tank body 110, and buffer pads are provided at the bottom of the legs. The tank body 110 is erected by the legs, and the discharge pipe 120 is erected for discharge. When vibration occurs, the impact force generated by the vibration is absorbed by the buffer pad, thereby reducing the vibration and the noise generated by the vibration.

[0033] Since the arc-shaped spring piece 520 needs to contact the outer wall of the discharge pipe 120 and knock the discharge pipe 120, in order to prevent the rotating arc-shaped spring piece 520 from hitting the discharge valve 130 when knocking, evenly distributed positioning holes are opened on the lower outer wall of the output shaft 240, and positioning bolts connected to the positioning holes are provided on the ring 510. The ring 510 slides up and down at the lower part of the output shaft 240 to adjust the position. After the position of the ring 510 is adjusted, the positioning hole is connected to fix the position by the positioning bolt, thereby realizing the adjustment and positioning of the position of the arc-shaped spring piece 520.

[0034] Since the arc-shaped spring piece 520 needs to continuously strike the discharge tube 120 , the arc-shaped spring piece 520 adopts a C-shaped elastic metal sheet to avoid damage caused by striking, and can rebound after contact deformation, which is convenient for subsequent striking.

[0035] During specific use, the phage powder and the feed are put into the tank body 110 through the quantitative feeding tube 220, and the motor 230 drives the output shaft 240 to rotate synchronously. The output shaft 240 drives the driven shaft 250 to rotate through the transmission gear 270, so that the output shaft 240 and the inclined blades 260 on the driven shaft 250 rotate in opposite directions to stir and mix the phage powder and the feed. The rotating inclined blades 260 continuously turn over the phage powder and the feed to improve the mixing effect. When the output shaft 240 rotates, it synchronously drives the driving bevel gear 280 to rotate, and the driving bevel gear 280 rotates through the driving gear 270. The driven bevel gear 320 drives the discharge shaft 310 to rotate, and the discharge shaft 310 synchronously drives the spiral blade 330 to rotate to perform spiral feeding. When the spiral blade 330 delivers the feed, the feed is extruded in strips through the extrusion hole 420, and feed particles are formed after breaking, which is convenient for feeding. When the spiral blade 330 rotates, the left end continuously cuts the strip feed on the end cover 410 to form feed particles. When the output shaft 240 rotates, it synchronously drives the ring 510 to rotate, so that the arc-shaped spring piece 520 continuously knocks on the discharge pipe 120, and the vibration generated by the knocking causes the feed to fall.

[0036] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
