[0002] Feed additives usually contain a variety of different ingredients, such as vitamins, minerals, amino acids, and various functional additives, etc., which have large differences in physical properties (such as particle size, density). When producing feed additives, a stirring device is needed to stir various additives uniformly.

[0003] A stirring device for producing feed additives is disclosed in Chinese Patent Publication No. CN212467873U, which includes a stirring box, a fixed frame, and a rotating rod. A motor is fixedly installed on the upper surface of the stirring box, and the power output end of the motor is fixedly connected with the rotating rod through a shaft coupling. The motor is rotatably connected with the stirring box through a bearing, and the rotating rod is fixedly connected with a spiral conveying structure through a bolt at one end. The spiral conveying structure is rotatably connected with the stirring box through a bearing at the other end. Two brackets are fixedly connected with the stirring box through bolts on both sides of the inner wall, and a fixed frame is fixedly connected with the adjacent ends of the two brackets through bolts. A feeding port is arranged on one side of the upper surface of the stirring box, and a discharging port is arranged at the bottom of one side of the stirring box. The device drives the rotating rod by the motor to rotate the spiral conveying structure, which conveys the feed and additives at the bottom of the stirring box to the upper side. This not only prevents uneven stirring of the additives, but also plays a role in stirring the feed, which can reduce the impact of uneven additives on the nutritional value of the feed. At the same time, the motor drives the rotating rod to rotate the connecting rod and the fixed plate, which scrapes the additives adhering to the inner wall of the stirring box, avoiding the reduction of the nutritional value of the feed due to the adhesion of additives.

[0028] As Figures 1-3As shown, the present application provides a kind of production feed additive stirring device, including the stirring box 1 with feed inlet 11 in top, the bottom of stirring box 1 is connected with discharge pipe 11, discharge pipe 11 is inserted with baffle 2, the inner bottom of stirring box 1 is funnel type, rotationally arranged with shaft 3 in stirring box 1, the lower end of shaft 3 extends to discharge pipe 11, the lower end of shaft 3 in discharge pipe 11 is equipped with screw conveying structure 4, stirring assembly 5 is arranged on shaft 3 in stirring box 1, the upper end of shaft 3 extends to stirring box 1 outside and is connected with driving motor 6, the top of stirring box 1 is equipped with lifting adjustment assembly 7 for driving shaft 3 and driving motor 6 to move upward or downward, when using, feed additive raw materials enter stirring box 1 by feed inlet 11 in the top of stirring box 1, driving motor 6 drives shaft 3 to rotate, drives stirring assembly 5 to rotate, and the feed additive raw materials in stirring box 1 are stirred and mixed, because the inner bottom of stirring box 1 is funnel type, material is gathered to discharge pipe 11 under the action of gravity, shaft 3 drives screw conveying structure 4 to rotate when rotating, and the feed additive raw materials gathered in discharge pipe 11 are conveyed upward, prevent the feed additive raw materials from being stirred unevenly, when discharging, driving motor 6 is closed, baffle 2 on discharge pipe 11 is extracted, and screw conveying structure 4 is moved upward by driving shaft 3 through lifting adjustment assembly 7, so that screw conveying structure 4 is separated from discharge pipe, material is gathered to discharge pipe 11 and is discharged under the action of gravity, compared with prior art, material in stirring box 1 can be effectively discharged, material residue is reduced, raw material waste is reduced, and production cost is reduced.

[0029] As Figure 1 and Figure 2 shown, lifting adjustment assembly 7 includes lifting cylinder 71, mounting plate 72 and two guide rods 73, lifting cylinder 71 is fixedly arranged on the top of stirring box 1, two guide rods 73 are symmetrically fixedly arranged on the top of stirring box 1, mounting plate 72 is movably arranged on two guide rods 73, the telescopic rod of lifting cylinder 71 is fixedly connected with mounting plate 72, driving motor 6 is fixedly arranged on mounting plate 72, the upper end of shaft 3 penetrates mounting plate 72 and is connected with the output shaft of driving motor 6, when lifting cylinder 71 drives mounting plate 72 to move upward or downward along two guide rods 73, driving motor 6 and shaft 3 also correspondingly carry out height adjustment, the symmetric arrangement of two guide rods 73 provides stable guiding effect for the movement of mounting plate 72, so that it can move stably along guide rod 73.

[0030] As Figure 2As shown in the figure, the bottom of the mounting plate 72 is fixedly provided with a positioning cylinder 8, which is sleeved on the rotating shaft 3, and the lower end of the positioning cylinder 8 can abut against the top of the stirring box 1. When the lifting cylinder 71 drives the mounting plate 72 to descend and the lower end of the positioning cylinder 8 abuts against the top of the stirring box 1, the distance between the lower end of the rotating shaft 3 and the top of the baffle 2 reaches a preset value, which is 1 cm in this embodiment. Thus, the baffle 2 is prevented from being worn by the contact between the lower end of the rotating shaft 3 and the top of the baffle 2 when the rotating shaft 3 rotates, and the feed additive raw materials in the barrel can be effectively upwardly conveyed to fully mix the feed additive raw materials.

[0031] As shown in the figure, Figure 2 and Figure 3 the stirring assembly 5 includes a plurality of stirring rods 51 uniformly arranged on the rotating shaft 3. The stirring rods 51 are located above the spiral conveying structure 4, and rotate with the rotating shaft 3 when the rotating shaft 3 rotates, thereby stirring the feed additive raw materials in the stirring box 1. The stirring rods 51 cooperate with the spiral conveying structure 4 to fully mix the feed additive raw materials of each component.

[0032] As shown in the figure, Figure 2 and Figure 3 the end of the stirring rod 51 away from the rotating shaft 3 is fixedly provided with a scraper 9, the side of the scraper 9 away from the stirring rod 51 is adapted to the inner wall of the stirring box 1, and the scraper 9 abuts against the inner wall of the stirring box 1. The scraper 9 moves synchronously with the stirring rod 51 when the stirring rod 51 rotates around the rotating shaft 3. In the stirring process, the feed additive raw materials adhering to the inner wall of the stirring box 1 can be scraped off and re-rolled into the stirring area in time, thereby promoting the full mixing of the feed additive raw materials of each component and further improving the mixing uniformity.

[0033] As shown in the figure, Figure 2 a bearing 10 is arranged between the positioning cylinder 8 and the rotating shaft 3, which ensures smooth and stable rotation of the rotating shaft 3.

[0034] As shown in the figure, Figure 2 a first sealing ring (not shown in the figure) is arranged at the connection between the rotating shaft 3 and the stirring box 1, and a second sealing ring (not shown in the figure) is arranged at the connection between the baffle 2 and the discharge pipe 11. The arrangement of the first and second sealing rings ensures the sealing of the stirring box 1, prevents the feed additive raw materials in the stirring box 1 from leaking and causing waste, and avoids pollution to the working environment.

[0035] As shown in the figure, Figure 1 in this embodiment, the driving motor 6 is a reversible motor, which can drive the rotating shaft 3 to rotate in both directions. The material in the discharge pipe 11 can be upwardly or downwardly conveyed. When discharging, the driving motor 6 drives the rotating shaft 3 to drive the spiral conveying structure 4 to downwardly convey the material, which can accelerate the discharging and prevent the material from being blocked in the discharge pipe 11.

[0036] The above merely provides preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the principles and technical scope of the present application shall fall into the scope of the present application.
