Description

Technical Field

[0001] This utility model belongs to the field of mixing and feeding technology, and in particular relates to a feeding device for a premixed material mixer. Background Technology

[0002] In the feed production process, feed needs to be mixed, which is divided into two key stages: premixing and blending. Premixing, as a pre-processing step before blending, directly affects the uniformity and fineness of the material supply, impacting the subsequent blending quality and the nutritional balance of the finished feed. Existing traditional feed premixing equipment requires a feeding mechanism or device for feeding. Traditional feeding devices include screw, belt, and vibratory feeding methods, but none of them lack a grinding mechanism for the feed. Specifically, when feed ingredients (especially vitamins, minerals, and other additives) are clumped, damp, or have uneven particle sizes, traditional feeding devices cannot break down and refine the material during the feeding process. This results in large particle size differences and poor flowability in the material entering the premixer, leading to material stratification, uneven mixing, and even blockage of conveying pipes and reduced equipment operating efficiency during the premixing stage.

[0003] Therefore, it is very necessary to invent a feeding device for a premixed material mixer. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a feeding device for a premix mixer, including a feeding machine box, a grinding feeding mechanism, a drive motor, a storage chamber, a transition chamber, a grinding chamber, a discharge port, and mounting columns. The feeding machine box is fixedly connected to the premix mixer through mounting columns fixedly installed at the four corners at the bottom. The discharge port installed at the bottom is connected to the inlet port of the premix mixer through a flange. The grinding feeding mechanism installed inside the feeding machine box is equipped with a drive motor. The feeding machine box has a communicating storage chamber, a transition chamber, and a grinding chamber.

[0005] Preferably, the storage chamber, transition chamber, and grinding chamber are arranged sequentially from top to bottom inside the feeding machine box, forming a vertically connected cavity structure.

[0006] Preferably, the material storage chamber is located inside the upper part of the feeding machine box, and the grinding chamber is located inside the lower part of it. The material storage chamber and the grinding chamber are conical cavity structures and are arranged opposite to each other.

[0007] Preferably, the grinding feeding mechanism fixedly installed inside the feeding machine housing includes a drive shaft, a fixed plate, a base, a feeding hole group, a pusher blocking plate, a grinding head, a spiral pattern, and spiral blades. The fixed plate and the base are rotatably mounted on the upper and lower ends of the drive shaft, respectively. The fixed plate and the base are fixedly installed on the upper and lower positions of the feeding machine housing, respectively. A drive motor is fixedly installed on the fixed plate fixed above the feeding machine housing, and the output end of the drive motor is fixed to the upper end of the drive shaft. An even number of feeding holes are opened through the base. Spiral blades are provided on the surface of the grinding head. The pusher blocking plate and the grinding head are fixedly installed on the lower end of the drive shaft, and spiral blades are installed in the upper area of ​​the drive shaft.

[0008] Preferably, the drive shaft is disposed in the storage chamber, the transition chamber and the grinding chamber, wherein the chassis rotatably mounted at the lower end of the drive shaft is fixedly mounted at the lower opening of the grinding chamber, wherein the pusher blocking plate and the grinding head fixedly mounted at the lower end of the drive shaft are disposed in the grinding chamber, the grinding head is located above the pusher blocking plate, the grinding head has a conical grinding structure, and the area below the outer surface of the grinding head is provided with spiral patterns.

[0009] Preferably, the spiral blades installed on the upper part of the drive shaft are located in the storage chamber and the transition chamber, and the spiral blades can drive the material in the storage chamber to be transported sequentially to the transition chamber and the grinding chamber.

[0010] Preferably, the material in the grinding chamber can fall into the discharge pipe through the feeding hole group opened in the chassis. The pushing and blocking plate can push the material on the chassis to move and can block the feeding hole group opened through the chassis. The number of pushing and blocking plates and the feeding hole group are the same.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention, by setting up a grinding-type feeding mechanism, utilizes the conical grinding structure of the grinding head and the spiral pattern on its outer surface to shear, squeeze, and grind feed raw materials with lumps or large particles during the feeding process, effectively improving the particle size uniformity and flowability of the material. No additional grinding equipment is required, simplifying the production process and reducing equipment costs.

[0013] This utility model has a storage chamber, a transition chamber, and a grinding chamber arranged vertically in series from top to bottom to form a cavity structure. The material falls faster by gravity, and the conical cavity design reduces the cross-sectional area of ​​the grinding zone, enhancing the grinding effect. The material passes through storage, transition, and grinding processes in sequence within the cavity, ensuring the continuity and stability of the material supply.

[0014] The combination of the pusher blocking plate and the feeding hole group in this utility model can drive the pusher blocking plate to move by rotating the drive shaft, thereby blocking or opening the feeding hole group on the chassis, accurately controlling the material output, avoiding the material leakage or metering deviation problems caused by the lack of a material interruption structure in traditional feeding devices, and improving the metering accuracy of the feeding.

[0015] In addition, the spiral blades in the upper part of the vertical shaft of this utility model can transport the material in the storage chamber to the transition chamber and the grinding chamber in sequence, forming a synergistic effect with the spiral pattern below the grinding head. The spiral pattern can not only guide the ground material to move downward, but also generate a forced pushing force on the material during the rotation process, ensuring efficient material discharge and improving feeding efficiency.

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a feeding device for a premixed material mixer, including a feeding machine box 1, a grinding feeding mechanism 2, a drive motor 3, a storage chamber 4, a transition chamber 5, a grinding chamber 6, a discharge port 7, and mounting columns 8. The feeding machine box 1 is fixedly connected to the premixed material mixer through the mounting columns 8 fixedly installed at the four corners at the bottom. The discharge port 7 installed at the bottom is connected to the inlet port of the premixed material mixer through a flange. The grinding feeding mechanism 2 installed inside the feeding machine box 1 is equipped with a drive motor 3. The feeding machine box 1 has a communicating storage chamber 4, a transition chamber 5, and a grinding chamber 6.

[0026] Furthermore, the feeding machine housing 1 is entirely welded from 304 stainless steel, possessing excellent corrosion resistance and strength. Its interior, from top to bottom, contains a storage chamber 4, a transition chamber 5, and a grinding chamber 6, forming a vertically connected structure. The storage chamber 4, transition chamber 5, and grinding chamber 6 are separated by the inner wall of the feeding machine housing 1, yet interconnected. This vertically connected chamber structure design allows materials to fall naturally under gravity, while also facilitating cooperation with components such as the drive shaft 21 to achieve material conveying and grinding.

[0027] Furthermore, the storage chamber 4 is located at the upper part of the feeder housing 1, and its shape is a conical structure that is wider at the top and narrower at the bottom. This design is beneficial for material storage and feeding, and can reduce material accumulation and bridging within the storage chamber 4. The grinding chamber 6 is located at the lower part of the feeder housing 1, opposite to the storage chamber 4. It also adopts a conical structure, but it is wider at the bottom and narrower at the top. This conical structure, in conjunction with the conical grinding structure of the grinding head 26, can achieve a better grinding effect on the material entering the grinding chamber 6 when the grinding head 26 rotates. The transition chamber 5 is located between the storage chamber 4 and the grinding chamber 6. It is a cylindrical structure and serves as a connection and transition, allowing material to smoothly enter the grinding chamber 6 from the storage chamber 4.

[0028] Furthermore, the grinding-type feeding mechanism 2 is the core component of the entire feeding device, and is fixedly installed inside the feeding machine housing 1. The drive shaft 21 is a cylindrical metal shaft, with its upper and lower ends rotatably mounted on the fixed plate 22 and the base 23 respectively via bearings. The base 23 is a circular metal plate. The fixed plate 22 and the base 23 are fixedly installed on the upper and lower positions of the feeding machine housing 1 by bolts, serving to support and fix the drive shaft 21. On the fixed plate 22 above the feeding machine housing 1, the drive motor 3 is fixedly installed by bolts. The drive motor 3 is a three-phase asynchronous motor, and its output end is fixedly connected to the upper end of the drive shaft 21 via a coupling, thereby driving the drive shaft 21 to rotate. An even number of feeding hole groups 24, for example, four groups, are opened through the base 23. Each group of feeding hole groups 24 consists of multiple evenly distributed circular holes for material discharge. The grinding head 26 is a conical metal structure with spiral blades 28 fixedly mounted on its surface. The spiral blades 28 are made of stainless steel and are fixed to the surface of the grinding head 26 by welding. Both the pusher blocking plate 25 and the grinding head 26 are bolted to the lower end of the drive shaft 21 and rotate with the drive shaft 21. Spiral blades 28 are also welded to the upper part of the drive shaft 21 for material conveying.

[0029] Furthermore, the drive shaft 21 passes through the storage chamber 4, the transition chamber 5, and the grinding chamber 6. Its lower end is rotatably mounted on the chassis 23 via bearings. The chassis 23 is bolted to the lower opening of the grinding chamber 6, sealing the lower opening and supporting the drive shaft 21. The pusher blocking plate 25 and the grinding head 26, both fixedly mounted at the lower end of the drive shaft 21, are located inside the grinding chamber 6. The grinding head 26 has a conical grinding structure and is located above the pusher blocking plate 25, with a certain gap between them to allow the material to be ground and conveyed within the grinding chamber 6. The lower area of ​​the outer surface of the grinding head 26 is provided with spiral patterns 27. The spiral patterns 27 are spiral protrusions machined on the outer surface of the grinding head 26, which guide the ground material downwards when the grinding head 26 rotates.

[0030] Furthermore, the spiral blades 28 installed on the upper part of the drive shaft 21 are located in the storage chamber 4 and the transition chamber 5. The spiral blades 28 are spiral-shaped metal sheets, fixed to the outer surface of the drive shaft 21 by welding. When the drive motor 3 drives the drive shaft 21 to rotate, the spiral blades 28 rotate accordingly. Utilizing the thrust of the spiral blades 28 and the gravity of the material, the material in the storage chamber 4 is lifted upwards and pushed downwards along the spiral direction of the spiral blades 28, sequentially transported to the transition chamber 5 and the grinding chamber 6, thus achieving continuous material conveying. The pitch and diameter of the spiral blades 28 are designed according to the dimensions of the storage chamber 4 and the transition chamber 5, as well as the material conveying capacity, to ensure smooth material conveying without blockage.

[0031] Furthermore, the material, after being ground in the grinding chamber 6, can fall through the feeding hole group 24 on the chassis 23 into the discharge pipe 7. The discharge pipe 7 is a cylindrical metal pipe, connected to the feed pipe of the premixer via a flange, thus conveying the material to the premixer. The pusher blocking plate 25 is fixedly installed at the lower end of the drive shaft 21, located above the chassis 23. When the drive shaft 21 rotates, the pusher blocking plate 25 rotates accordingly, pushing the material on the chassis 23 to fall through the feeding hole group 24. Simultaneously, the number of pusher blocking plates 25 is the same as the number of feeding hole groups 24, for example, four in each case. When the pusher blocking plate 25 rotates to the position corresponding to the feeding hole group 24, it blocks the feeding hole group 24, preventing material from falling, thereby controlling the material output. The shape and size of the pusher blocking plate 25 match the feeding hole group 24 to ensure effective blocking of the feeding hole group 24.

[0032] The working principle is as follows: First, the material enters the feeding machine box 1 through the conical opening above the storage chamber 4 and is stored in the storage chamber 4. When the drive motor 3 starts, the drive shaft 21 rotates accordingly, driving the spiral blades 28 installed in its upper region to rotate. During the rotation process, the spiral blades 28 use their own spiral structure and the gravity of the material to lift the material in the storage chamber 4 upward and push it downward along the spiral direction, so that the material passes through the transition chamber 5 and enters the grinding chamber 6 in sequence.

[0033] Next, the material enters the grinding chamber 6 and comes into contact with the rotating grinding head 26. The conical grinding structure of the grinding head 26 cooperates with the conical cavity of the grinding chamber 6 to shear, squeeze, and grind the material during rotation, breaking down and refining agglomerated or large particles. At the same time, the spiral pattern 27 in the area below the outer surface of the grinding head 26 generates a downward thrust during rotation, guiding the ground material toward the chassis 23.

[0034] Subsequently, as the drive shaft 21 rotates, the pusher blocking plate 25 rotates synchronously. When the pusher blocking plate 25 rotates to the position other than the feed hole group 24, the feed hole group 24 on the chassis 23 is open. Under the action of gravity and the thrust of the spiral pattern 27, the ground material falls through the feed hole group 24 into the discharge pipe 7, and is finally conveyed to the premixer through the discharge pipe 7. When the pusher blocking plate 25 rotates to the position of the feed hole group 24, the feed hole group 24 is blocked, and the material cannot fall temporarily. By controlling the rotation speed of the drive shaft 21 and the position of the pusher blocking plate 25, precise control of the material output can be achieved.

[0035] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
