[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the utility model.

[0025] like Figures 2 to 7 As shown, this embodiment discloses a feed mixing device, including a mixing shell 3, the mixing shell 3 is in the shape of a cylindrical shell, and a feeding mechanism is arranged at the top of the mixing shell 3; the bottom end of the mixing shell 3 is arranged in a constricted shape and a discharge port 303 is arranged at the bottom end of the constricted shape, and a discharge baffle 12 for controlling the opening and closing state of the discharge port 303 is arranged at the bottom end of the discharge port 303;

[0026] The feeding mechanism includes four feeding hoppers 4, a power motor 8, and a material control plate 5; four feeding ports 301 are arranged at equal intervals at the top of the mixing shell 3 along the circumferential direction of the mixing shell 3, and the four feeding hoppers 4 are fixedly connected to the top of the mixing shell 3 and the bottoms of the four feeding hoppers 4 are arranged corresponding to the four feeding ports 301;

[0027] The material control plate 5 is in the shape of a circular plate, which is located at the top of the mixing shell 3 and is coaxially arranged with the mixing shell 3. The center position of the material control plate 5 is transmission-connected to the power motor 8 fixedly connected to the mixing shell 3 and the material control plate 5 is driven to rotate by the power motor 8. A material through hole 501 is arranged at an eccentric position on the material control plate 5 and the material through hole 501 is arranged corresponding to the discharge port 301; when the material control plate 5 rotates, one of the discharge ports 301 is in a separate communication state with the material through hole 501.

[0028] After installation, the gap between the material control plate and the upper end surface of the mixing shell is very small. When it rotates, only one material discharge port is connected to the material through-hole, and the other three material discharge ports are blocked by the material control plate, so that the materials in the four feed hoppers enter the mixing shell in turn; when designing, the material through-hole is designed as an arc long hole structure, which can increase the feeding time of each material when the material control plate rotates, but care should be taken to avoid the situation where the material through-hole is too long, which may cause two materials to be fed at the same time.

[0029] A material blocking assembly is provided on one side of the interior of the feed hopper 4, and the material blocking assembly includes a material blocking plate 13 and an adjusting bolt 14; the material blocking plate 13 is located on one side of the upper end of the discharge port 301 and the upper end of the material blocking plate 13 is connected to the pin shaft of the inner wall of the feed hopper 4, a bolt through hole is provided on the side wall of one side of the material blocking plate 13 and the adjusting bolt 14 is threadedly connected through the bolt through hole, and one end of the adjusting bolt 14 passes through the bolt through hole and abuts against the end face of the end of the material blocking plate 13 close to the inner wall of the feed hopper 4; when the adjusting bolt 14 is rotated and screwed in toward the inside of the feed hopper 4, the end of the adjusting bolt 14 pushes the bottom end of the material blocking plate 13 to rotate, so as to adjust and control the feeding rate of the discharge port 301, such as Figure 3 , Figure 4 shown.

[0030] By controlling the regulating bolt, the position of the baffle plate can be adjusted, thereby controlling the feeding rate of different materials, making it convenient to control the configuration amount of various materials in the feed, so that materials with a smaller configuration amount can also form an overall material stratification effect through a slower feeding rate, thereby improving the uniformity of pig feed preparation.

[0031] A material guide plate 6 is fixedly connected to the inside of the mixing shell 3, and the material guide plate 6 is located below the material control plate 5; the material guide plate 6 is arranged in a funnel shape and a collection port 601 is arranged at the bottom of the material guide plate 6, and the diameter of the collection port 601 is larger than the cross-sectional outer diameter of the transmission shaft 9, and the top edge of the material guide plate 6 is fixedly connected to the inner wall of the mixing shell 3.

[0032] The guide plate can make the materials entering from different discharge ports converge to the collection port and fall down, thus forming a layered stacking effect of various materials, avoiding the situation that after the materials fall from their respective discharge ports, four material areas are formed on the plane, which makes it more difficult to mix them evenly.

[0033] A filter element 7 is rotatably connected to the interior of the mixing shell 3, and the filter element 7 is located below the material guide plate 6; the filter element 7 is arranged in a conical screen shape, and the bottom edge of the filter element 7 is rotatably connected to the inner wall of the mixing shell 3 through a bearing element, and the top center position of the filter element 7 is transmission-connected to the power motor 8 and the filter element 7 is driven to rotate by the power motor 8.

[0034] The side wall of the mixing shell 3 is provided with a slag discharge port 302 connected to the inside of the mixing shell 3, and the slag discharge port 302 is located on the upper side of the bottom edge of the filter 7; the outer side of the slag discharge port 302 is provided with a slag discharge baffle 11 for controlling the opening and closing state of the slag discharge port 302.

[0035] After the material falls through the collection port at the bottom of the guide plate, it will be diverted and screened on the conical surface of the filter element. Larger material lumps or impurities will roll along the conical surface of the filter element to the edge of the filter element, and can be cleaned through the slag discharge port after a period of time. The design of the filter element being driven to rotate by the power motor can disperse the material falling on the filter element onto the conical surface of the filter element under the action of centrifugal force, quickly achieve the filtering and screening effect, avoid material accumulation and slow screening rate, and improve the material screening rate.

[0036] The power motor 8 is fixedly connected to the center position of the top of the mixing shell 3, and the power motor 8 is connected to the top of the transmission shaft 9. The bottom end of the transmission shaft 9 extends into the mixing shell 3 and passes through the center position of the material control plate 5 and the collection port 601 at the bottom end of the material guide plate 6 in sequence, and then is connected to the center position of the top of the filter element 7.

[0037] A stirring mechanism is provided at the lower part of the mixing shell 3 ; the stirring mechanism comprises a stirring blade 10 , and the stirring blade 10 is located below the filter 7 ; the bottom end of the transmission shaft 9 passes through the center position of the top end of the filter 7 and is fixedly connected to the stirring blade 10 .

[0038] When performing material mixing operations, first, the power motor drives the transmission shaft to rotate slowly, so that various materials gradually enter the mixing shell and accumulate under the filter element. During this process, the stirring blades slowly stir the materials entering the mixing shell; after all the materials in the feed hopper enter the mixing shell, the power motor electric transmission shaft and the stirring blades rotate quickly, and the even mixing operation of the accumulated materials can be completed in a short time.

[0039] When the utility model is used, after the four materials 15 are piled into the mixing housing 3, the pile structure is as follows: Figure 7 As shown in the figure, the thickness value of each material 15 is small, and it finally forms a layered structure with a small thickness, which can easily achieve a uniform stirring effect of the material; while in the batching device of the prior art, each material 2 is directly placed in the stirring shell 1, resulting in a large thickness value of each material 2, and the layered structure formed also has a large thickness value (such as Figure 1 As shown in the figure, it is not easy to achieve uniform stirring of the material in the longitudinal direction during stirring, the technical effect is poor, and the quality of the produced pig feed is difficult to guarantee.

[0040] The utility model adopts the design of arranging a feeding mechanism at the top of the mixing shell, so that when performing the batching operation, different materials are first placed in different feeding hoppers respectively, and then the power motor drives the material control plate to rotate. When the material through hole on the material control plate rotates to below a certain discharge port, the material in the feeding hopper above the discharge port will enter the mixing shell through the discharge port and the material through hole in turn; as the material control plate continues to rotate, the materials in multiple feeding hoppers enter the mixing shell from the material through holes in turn, and under the action of the guide plate, multiple materials finally form a layered structure with a smaller thickness in the mixing shell; when the material layered structure is mixed, the material only needs to move a small amount in the longitudinal direction to achieve the longitudinal mixing effect, which makes it easier to achieve the mixing uniformity of the overall material, thereby effectively improving the production quality of pig feed; and the utility model has the advantages of simple structure, low cost, and easy operation, which can significantly improve the mixing uniformity of pig feed and has excellent market promotion prospects.
