[0024] A guide plate 92 is fixed on the side of the discharge hopper 9 for limiting the baffle 91. When the baffle 91 blocks and seals the discharge port, the guide plate 92 limits the baffle 91 to ensure that the baffle 91 effectively blocks and seals the discharge port.

[0028] A spraying assembly is slidingly arranged on the top of the inner cavity of the mixing tank 1, and grease is sprayed into the material in the mixing tank 1 through the arranged spraying assembly. The sliding of the spraying assembly is synchronized with the rotation of the stirring shaft 4, that is, during the stirring process of the stirring assembly, the position of the spraying assembly moves, which is convenient for spraying grease at different positions, avoiding excessive grease spraying at a single grease spraying position, and improving the mixing efficiency of various materials and grease.

[0029] The top of the mixing tank 1 is open, and a removable sealing cover 3 is provided at the open part of the mixing tank 1. By removing the sealing cover 3, it is convenient to clean the inside of the mixing tank 1 or maintain and replace the internal components of the mixing tank 1. The stirring shaft 4 passes through the sealing cover 3 and extends to the top of the mixing tank 1. Several groups of positioning components are provided on the lower side of the sealing cover 3. The positioning components include a mounting frame 6 and a guide rod 64. The guide rod 64 is fixed to the lower part of the side of the sealing cover 3. A positioning plate 63 is fixed to the side of the mounting frame 6. The positioning plate 63 is slidably connected to the guide rod 64. A second gear 44 located at the top of the inner cavity of the mixing tank 1 is fixed to the side of the stirring shaft 4. The spraying component is installed in the mounting frame 6. Several latch teeth 65 are installed on the side of the mounting frame 6, and the latch teeth 65 are meshed with the second gear 44.

[0030] When the electric telescopic cylinder 51 drives the stirring shaft 4 to rotate, the stirring shaft 4 drives the second gear 44 to rotate synchronously, and the second gear 44 drives the mounting frame 6 to move through the latch 65 on the side of the mounting frame 6, so that the mounting frame 6 drives the spraying component to move to adjust the spraying position of the spraying component, so as to avoid the spraying component always spraying grease towards the same position, resulting in excessive grease at that position, and adopting the mobile spraying method to improve the mixing efficiency of the material and grease, so as to facilitate the mixed preparation of piglet feed; preferably, the positioning component is provided with two groups, that is, two groups of spraying components are provided, and under the influence of the second gear 44, the two groups of spraying components move in opposite directions, so as to facilitate the spraying of grease to multiple positions during the stirring process.

[0031] The spray assembly includes a spray tube 61 installed in the installation frame 6, and a nozzle 62 connected to the inner cavity of the spray tube 61 is installed on the side of the spray tube 61.

A delivery pipe 73 is provided at the discharge end of the liposuction pump 71, and a shunt pipe 74 is installed at the end of the delivery pipe 73 away from the liposuction pump 71. The delivery pipe 73 is connected to the inner cavity of the spray assembly in several groups of positioning components through the shunt pipe 74. The shunt pipe 74 is fixed on the side of the spray tube 61 and is connected to the inner cavity of the spray tube 61. The liposuction pump 71 is controlled to work, and the liposuction pump 71 extracts grease from the grease storage box 7 through the connecting pipe 72, and the liposuction pump 71 conveys the extracted grease to the diversion pipe 74 through the conveying pipe 73, and the diversion pipe 74 conveys the grease to each spraying pipe 61, and the grease entering the spraying pipe 61 is sprayed on the outside of the material through the nozzle 62, and is fully mixed under the stirring action of the stirring component; the spraying amount and spraying speed of the grease in the spraying component can be achieved by adjusting the working state of the liposuction pump 71, so as to spray an appropriate amount of grease according to the amount of material in the mixing tank 1, so as to avoid excessive grease affecting the quality of the feed, and at the same time prevent too little grease from having an effective benefit.

[0032] A cleaning rack 66 is fixed to the lower side of the sealing cover 3 near the mounting frame 6, and a cleaning plate 67 is fixed to the side of the cleaning rack 66, and the cleaning plate 67 is in sliding contact with the nozzle of the nozzle 62. During the movement of the mounting frame 6, the fixed cleaning rack 66 and the spray pipe 61 move relative to each other, so that the nozzle of the nozzle 62 can be cleaned by the cleaning plate 67 on the side of the cleaning rack 66 to avoid grease accumulation and clogging of the nozzle 62.

[0033] It should be noted that rosemary extract can significantly enhance the antioxidant capacity of soybean oil, inhibit the lipid oxidation reaction of soybean oil during processing and storage, thereby extending its shelf life. Rosemary also has the effect of antibacterial and antiseptic, can effectively inhibit the growth of microorganisms in soybean oil, and maintain its sanitary quality. In addition, rosemary contains a variety of beneficial ingredients, such as vitamins, minerals, etc., which can further improve the nutritional value of soybean oil. After the rosemary effective ingredients are extracted, they are mixed into soybean oil to prepare special grease, and then the special grease is sprayed on the outside of the material and mixed into feed, which increases the energy density and nutritional value of the feed, makes it easier to digest and absorb, can effectively improve the immune function of piglets, and provide sufficient nutrition for piglets; at the same time, an appropriate amount of grease spraying can improve the taste of feed, increase the appetite and feed intake of animals, and promote the growth and development of piglets.

[0034] The electric telescopic cylinder 51, liposuction pump 71, servo motor 83, etc. used in the present invention are all commonly used electronic components in the prior art, and their working methods and circuit structures are all well-known technologies. The operation of the electric telescopic cylinder 51, liposuction pump 71, servo motor 83 and other electronic components is controlled by setting a switch group or a PLC controller, and this method is a commonly used technical means for technicians and will not be elaborated here.

[0035] When using: The material to be mixed is put into the feed barrel 81, and the material enters the conveying barrel 8 through the feed barrel 81. The servo motor 83 is controlled to drive the auger conveying structure 82 to rotate, and the auger conveying structure 82 conveys the material in the conveying barrel 8 to the mixing tank 1 to realize the addition of the material. During the material adding process, the material adding amount or material adding speed can be controlled by the auger conveying structure 82.

[0036] The electric telescopic cylinder 51 is controlled to work and extend. During the extension and retraction process, the electric telescopic cylinder 51 drives the rack 5 to reciprocate, and the rack 5 drives the first gear 43 meshing with it to rotate, so that the stirring component rotates forward and reversely, thereby improving the material mixing efficiency. Traditional stirring components usually rotate in the same direction. During the rotation, it is not easy for the material to adhere to the front of the stirring component, but a large amount of material usually adheres to the back of the stirring component, affecting the material mixing efficiency. The stirring component in this solution adopts a forward and reverse rotation method to reduce the adhesion of the material on the stirring component.

[0037] During the material stirring process, the liposuction pump 71 is controlled to work, and the liposuction pump 71 extracts grease from the grease storage box 7 through the connecting pipe 72, and the liposuction pump 71 transports the extracted grease to the diversion pipe 74 through the delivery pipe 73, and the diversion pipe 74 transports the grease to each spray pipe 61. The grease entering the spray pipe 61 is sprayed on the outside of the material through the nozzle 62, and is fully mixed under the stirring action of the stirring component.

[0038] When the electric telescopic cylinder 51 drives the stirring shaft 4 to rotate, the stirring shaft 4 drives the second gear 44 to rotate synchronously. The second gear 44 drives the mounting frame 6 to move through the latch teeth 65 on the side of the mounting frame 6, so that the mounting frame 6 drives the spray pipe 61 to move to adjust the spraying position of the spraying component, thereby preventing the spraying component from always spraying grease at the same position, resulting in excessive grease at that position. The mobile spraying method is used to improve the mixing efficiency of the material and grease, which is convenient for the mixing preparation of piglet feed.

[0039] Affected by the telescopic movement of the electric telescopic cylinder 51, the installation frame 6 drives the spray pipe 61 to move back and forth, which is convenient for the mobile use of the spray assembly, and during the movement of the installation frame 6, the fixed cleaning rack 66 moves relative to the spray pipe 61, which is convenient for cleaning the nozzle of the nozzle 62 through the cleaning plate 67 on the side of the cleaning rack 66, avoiding grease accumulation and clogging the nozzle 62, and facilitating the use of the spray assembly.

[0040] After the feed is prepared and mixed, a person pushes the baffle 91 to move and open the discharge port. Under the stirring action of the spiral blade 41 in the stirring assembly, the mixed feed in the mixing tank 1 is forced to be discharged from the discharge port, making it easy to take the prepared feed out of the mixing tank 1; the discharge hopper 9 arranged at the discharge port plays a guiding and conveying role to prevent the feed from spilling when it is taken out.

[0041] The undisclosed parts in the present invention are all prior art, and their specific structures, materials and working principles are not described in detail. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
