[0029] See also Figure 1 As shown, a feed mixing device comprises a box body 1, the cross section of the box body 1 is circular, a feed port 2 is arranged at the center of the top of the box body 1, a feed hopper 3 is connected to the feed port 2, the lower end of the feed hopper 3 is located in the box body 1, a discharge port 4 is arranged at the bottom of the box body 1, a supporting leg structure is fixed on the bottom surface of the box body 1, the feed enters the box body 1 from the feed port 2 via the feed hopper 3, and is discharged from the box body 1 from the discharge port 4; a mixing and stirring device is arranged in the box body 1, and different feed raw materials can be mixed in the box body 1.

[0030] The box body 1 is provided with an annular notch 5, which divides the box body 1 into an upper box body and a lower box body, and a collecting box 6 is detachably connected to the outside of the box body 1, and the collecting box 6 connects the upper box body and the lower box body; the mixing and stirring device is located in the lower box body, and a sieve plate 12 is provided at the upper opening of the lower box body. The material is sieved by the sieve plate 12 before entering the lower box body, and large particles in the material are filtered out, so that small particles fall into the lower box body, which is convenient for subsequent mixing.

[0031] The mixing and stirring device includes a driving motor 7, which is fixed at the bottom center of the box body 1. A first through hole is provided at the bottom center of the box body 1. An output shaft 8 of the driving motor 7 passes through the first through hole, and the output shaft 8 of the driving motor 7 is connected to a stirring shaft 9. The stirring shaft 9 and the output shaft 8 of the driving motor 7 are coaxially arranged. The stirring shaft 9 is located in the box body, and the upper end of the stirring shaft 9 passes through the center of the sieve plate 12. A first stirring blade 10 and a second stirring blade 11 are provided on the stirring shaft 9. The first stirring blade 10 is located above the sieve plate 12, and the second stirring blade 11 is provided on the stirring shaft 9. The mixing blade 11 is located below the sieve plate 12, and the first mixing blade 10 and the second mixing blade 11 are both connected to the mixing shaft 9. When the driving motor 7 is working, the first mixing blade 10 and the second mixing blade 11 rotate accordingly. The second mixing blade 11 can mix the feed in the box body 1, and the first mixing blade 10 can move the material on the sieve plate 12. In addition, a dredging blade 13 is also provided on the mixing shaft 9. The dredging blade 13 is located in the feed hopper 3. The dredging blade 13 can dredge the material in the feed hopper 3 to avoid blockage of the feed.

[0032] See also Figure 1 , Figure 2 and Figure 3 As shown, the sieve plate 12 includes a center plate 1201 and a material guide plate 1202, the center plate 1201 is provided with a downwardly concave accommodation space, and a second through hole 20 is provided at the center of the center plate 1201, the upper end of the stirring shaft 9 passes through the second through hole 20, and a sieve hole 20 is provided around the second through hole in the accommodation space of the center plate 1201. At this time, the first stirring blade 10 is located in the accommodation space. When the material falls into the accommodation space, the first stirring blade 10 moves with the rotation of the stirring shaft 9, thereby moving the material in the accommodation space. In the process of material movement, particles smaller than the diameter of the sieve hole will fall into the lower box body;

[0033] The material guide plate 1202 is annular and is also provided with sieve holes. The inner edge of the material guide plate 1202 is connected to the outer edge of the center plate 1201, and the connection is an arc transition. The horizontal height of the outer edge of the material guide plate 1202 is lower than the height of its inner edge. At the same time, a partition mesh tube 14 is provided at the connection between the material guide plate 1202 and the center plate 1201. The holes on the partition mesh tube 14 are equal to the size of the sieve holes. At this time, after the material in the accommodating space is moved by the first stirring blade 10, the material will move with it. Under the action of centrifugal force, the material with a diameter smaller than the holes on the partition mesh tube 14 will pass through the partition mesh tube 14 and enter the collection box. Such a setting can allow the material to enter the lower box through two channels, thereby increasing the flow efficiency of the material and avoiding the problem of accumulation and blockage in the accommodating space.

[0034] See also Figure 1 , Figure 4 and Figure 5 As shown, in addition, a notch extending upward is provided at the lower edge of the first stirring blade 10, and there are several notches and the several notches are arranged along the length direction of the first stirring blade 10, so that the first stirring blade forms a tooth rake-like structure. During the movement of the first stirring blade 10, the material can be stirred to a certain extent to increase the mixing effect. At the same time, there are several first stirring blades 10, and several first stirring blades 10 are fixed on the positioning sleeve 15. The positioning sleeve is sleeved on the stirring shaft and is fixedly connected to the stirring shaft. Several first stirring blades 10 are arranged in a circular array around the central axis of the stirring shaft to initially increase the stirring efficiency.

[0035] Since the materials retained in the accommodating space are mostly large-particle materials, an extension sheet 16 is also fixed on the positioning sleeve 15. The extension sheets 16 are also arranged in a circular array around the positioning sleeve 15, but each extension sheet 16 is located between two adjacent first stirring blades 10. A sliding sheet 17 is arranged at the end of each extension sheet 16. The sliding sheet 17 is inclined. The angle α formed between the plane where the sliding sheet 17 is located and the first stirring blade 10 is 40-70°. When the sliding sheet 17 moves with the first stirring blade 10, the material can enter between the sliding sheet 17 and the bottom surface of the accommodating space. The gap between the low edge of the sliding sheet 17 and the bottom surface of the accommodating space is equal to the diameter of the hole on the center disk. In this way, the large-particle materials can be crushed by the sliding sheet, and finally the material reaches a diameter that can pass through the hole on the center disk, thereby further increasing the mixing efficiency.

[0036] See also Figure 1 and Figure 6As shown, the bottom surface of the above-mentioned collecting box 6 is an inclined surface, that is, the bottom of the collecting box 6 is funnel-shaped, and the lower box body includes an upper cylinder and a lower barrel. There is a gap between the upper cylinder and the lower barrel, and the sieve plate 12 is fixed to the upper end of the upper cylinder. An inclined support plate 18 is arranged on the bottom surface of the collecting box 6, and one end of the inclined support plate 18 is located between the upper cylinder and the lower barrel, and the inclined support plate is connected to the upper cylinder and the lower barrel at the same time. At this time, a feeding channel 19 is formed between the upper cylinder and the lower barrel, so that the material particles entering the collecting box 6 can smoothly enter the lower box for mixing.

[0037] When using the device, first seal the discharge port 4, then start the motor, add feed to the feed port 2, the feed is screened by the sieve plate 12, and the feed smaller than the diameter of the sieve hole of the sieve plate 12 falls into the lower box and is stirred by the mixing and stirring device. The large particles of feed intercepted by the sieve plate 12 are stirred by the first stirring blade, which initially increases the stirring efficiency and avoids the accumulation of feed in the accommodating space. In this process, the sliding plate on the extension plate crushes the large particles of feed, and finally makes the material reach a diameter that can pass through the holes on the center plate, further increasing the stirring efficiency.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
