Description

Technical Field

[0001] The present invention relates to the technical field of feed processing, and particularly to a mixing device for liquid feed premix. Background Art

[0002] Liquid feed refers to feed in a stable state formed by pre-mixing dry feed with water or some liquid by-products of the food industry in a certain proportion and then through fermentation or non-fermentation methods. Compared with solid feed, liquid feed has its advantages in reducing production costs and improving the growth performance of nursing piglets and weaned piglets.

[0003] During the production process of liquid feed, vitamins and amino acids are also added to improve the nutritional content. The vitamins, amino acids, dry feed, and water are placed in a mixing tank for premixing. When a large amount of liquid feed is produced, the amounts of vitamins, amino acids, and dry feed placed in the mixing tank also increase. However, in farms, vitamins, amino acids, and dry feed are often purchased in bags. This means that not only is it necessary to frequently open the bags, but the mixing tank itself also has a certain height, which means that the staff needs to hold the feed bags in a lifted position for pouring for a period of time. This is not only time-consuming and laborious, but also the input materials are likely to concentrate at the bottom of the tank and are unevenly distributed, which will affect the efficiency and quality of the liquid feed premix. For this reason, we propose a mixing device for liquid feed premix. Summary of the Invention

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The present invention provides a technical solution: as Figure 1 - Figure 7 shown, a liquid feed premix mixing device includes a mixing tank 3. A discharge assembly is provided at the bottom end of the mixing tank 3. A rotating column 10 is rotatably arranged at the center inside the mixing tank 3 through a driving mechanism. A bearing ring 11 is rotatably sleeved on the outer wall of the mixing tank 3. A plurality of stirring blades 12 are fixedly connected to the outer wall of the rotating column 10. At the upper edge of the outer wall of the rotating column 10, a plurality of square blocks 36 are fixedly connected (as Figure 7 shown). A feeding mechanism is provided between each of the plurality of square blocks 36 and the bearing ring 11;

[0029] The feeding mechanism includes a connecting plate 6 and an electric push rod 14. The connecting plate 6 is fixedly connected to the end of the square block 36 away from the rotating column 10. The electric push rod 14 is fixedly installed on the upper end of the bearing ring 11. Diagonal brace plates 5 are symmetrically and fixedly connected to the wall surface of the connecting plate 6 away from the square block 36. A support assembly is provided between the two diagonal brace plates 5 and the mixing tank 3. Two mutually fitting saw plates 23 are provided between the two diagonal brace plates 5. A position-changing mechanism is provided between the two saw plates 23 and the electric push rod 14.

[0030] The discharge assembly includes a discharge pipe 2. The discharge pipe 2 is communicated with the bottom end of the mixing tank 3. A valve 1 is installed on the discharge pipe 2.

[0031] Specifically, opening the valve 1 can discharge the liquid feed mixed inside the mixing tank 3 along the discharge pipe 2.

[0032] The driving mechanism includes three support frames 4. One ends of the three support frames 4 are all fixedly connected to the outer wall of the mixing tank 3. A triangular block 8 is fixedly connected together between the other ends of the three support frames 4. The triangular block 8 is located directly above the mixing tank 3. The three support frames 4 are all located outside the bearing ring 11. A motor 7 is fixedly installed at the lower end of the triangular block 8. The output shaft end of the motor 7 is fixedly connected to the top end of the rotating column 10.

[0033] Specifically, the three support frames 4 and the triangular block 8 are used to support and fix the motor 7. Starting the motor 7 can drive the rotating column 10 to rotate slowly.

[0034] The supporting component includes a support ring 9. The support ring 9 is slidably embedded at the upper edge near the inner wall of the mixing tank 3. A splicing rod 24 is fixedly connected between the inner ring surface of the support ring 9 and the mutually remote wall surfaces of the two inclined support plates 5.

[0035] Specifically, when the multiple inclined support plates 5 are driven to rotate, each inclined support plate 5 will drive the respective connected splicing rod 24 to rotate together. The multiple splicing rods 24 will drive the support ring 9 to rotate in a fitting manner on the inner wall of the mixing tank 3, which will neither cause movement interference nor play a stable supporting role for the inclined support plates 5, and add a stress point.

[0036] The position-changing mechanism includes a support plate 15. The support plate 15 is fixedly connected to the telescopic shaft end of the electric push rod 14. A concave plate 25 is attached to the upper end of the support plate 15. A guiding component and a reciprocating driving component are respectively arranged between the concave plate 25 and the support plate 15. A screw column 20 and a limiting column 29 are respectively rotatably connected between the two inner vertical wall surfaces of the concave plate 25. A transmission component is arranged at one end of the screw column 20. The threads on both sides of the outer wall of the screw column 20 are symmetrically arranged. Sliding blocks 21 are threadedly sleeved on both sides of the outer wall of the screw column 20. The limiting column 29 movably penetrates through the two sliding blocks 21. One ends of the two sliding blocks 21 corresponding to the mixing tank 3 are respectively rotatably connected with a rotating shaft 32. One ends of the two rotating shafts 32 far from the sliding blocks 21 are fixedly connected with a connecting block 22. The mutually corresponding wall surfaces of the two connecting blocks 22 are respectively fixedly connected with the mutually remote wall surfaces of the two saw plates 23. A linkage component is arranged between the two rotating shafts 32 and the concave plate 25.

[0037] The guiding component includes two guide columns 30. The two guide columns 30 are respectively slidably inserted into the two vertical walls of the concave plate 25. The two guide columns 30 are close to the upper end of the support plate 15. Both ends of the two guide columns 30 are fixedly connected with fixing blocks 28. The lower ends of the two fixing blocks 28 are fixedly connected to the upper end of the support plate 15.

[0038] Specifically, by setting the guide posts 30 and the fixed blocks 28, when the concave plate 25 is driven at the upper end of the support plate 15 and slides back and forth, the concave plate 25 will slide back and forth outside the two guide posts 30, improving the stability of the concave plate 25.

[0039] The reciprocating drive assembly includes a square frame 16, which is fixedly connected to the upper end of the support plate 15 away from the concave plate 25. A second motor 17 is fixedly installed at the upper end of the square frame 16. The output shaft end of the second motor 17 is fixedly connected to a turntable 18. An eccentric position on the wall surface of the turntable 18 away from the second motor 17 is rotatably connected to a connecting rod 13. One end of the connecting rod 13 away from the turntable 18 is rotatably connected to a splicing plate 26. The wall surface of the splicing plate 26 away from the connecting rod 13 is fixedly connected to the concave plate 25.

[0040] The transmission assembly includes a support block 27, which is fixedly connected to one of the outer vertical wall surfaces of the concave plate 25. A third motor 19 is fixedly installed at the upper end of the support block 27. The output shaft of the third motor 19 passes through the vertical wall of the concave plate 25 movably. The output shaft end of the third motor 19 is fixedly connected to one end of a stud 20.

[0041] Specifically, starting the third motor 19 can drive the stud 20 to rotate.

[0042] The linkage assembly includes two gears 33 and two L-shaped plates 35. The two gears 33 are respectively fixedly sleeved on the outer walls of two rotating shafts 32. Two torsion springs 31 are fixedly connected between the two gears 33 and the two sliders 21 respectively. The two torsion springs 31 are respectively slidably sleeved on the outer walls of the two rotating shafts 32. One end of each of the two L-shaped plates 35 is symmetrically fixedly connected to the wall surface of the concave plate 25 away from the splicing plate 26. The other end of each of the two L-shaped plates 35 is fixedly connected to a toothed plate 34. One end of each of the two toothed plates 34 away from the L-shaped plate 35 is respectively close to the two gears 33.

[0043] The bottom ends of the two connecting blocks 22 and the bottom ends of the two saw plates 23 are both provided with rounded corners.

[0044] Specifically, the bottom ends of the two connecting blocks 22 are both arc-shaped surfaces, which makes it less likely for the bottom ends of the two connecting blocks 22 to come into contact with each other during reverse rotation, causing movement interference. Similarly, the same is true for the two saw plates 23. At the same time, when the two connecting blocks 22 rotate in opposite directions, they will not be blocked by the upper end surface of the mixing tank 3.

[0045] Working principle: First, an appropriate amount of water is placed into the mixing tank 3. Subsequently, the long sides of the vitamin bag, amino acid bag, and dry feed bag can be inserted respectively between two diagonal braces 5 connected to multiple connecting plates 6. Then, the vitamin bag, amino acid bag, and dry feed bag will be stuck between the corresponding two diagonal braces 5, and the bag body is adjusted to be straightened. Subsequently, the electric push rod 14 corresponding to the dry feed bag is first started. The electric push rod 14 can drive the corresponding supporting plate 15, two mutually attached saw plates 23, and other structures connected to the supporting plate 15 and the two saw plates 23 to move upward together. The two saw plates 23 can first pierce the long side of the dry feed bag upward, and the two saw plates 23 extend into the dry feed bag for a short distance. Then, the second motor 17 is started. The second motor 17 can drive the turntable 18 to rotate. The turntable 18 can drive the connecting rod 13 to swing reciprocally first backward and then forward, and the swing amplitude is small. Then, the connecting rod 13 can drive the splicing plate 26 and the concave plate 25 to move reciprocally for a short distance. The concave plate 25 can drive the stud 20, the limit post 29, two sliders 21, two rotating shafts 32, two gears 33, two torsion springs 31, two connecting blocks 22, and the two saw plates 23 to move reciprocally for a short distance. Then, the two saw plates 23 can saw open the long side of the dry feed bag. At this time, the material in the dry feed bag can fall into the mixing tank 3 along the saw cut in small amounts.

[0046] Subsequently, the transmission component can drive the stud 20 corresponding to the dry feed bag to rotate. Since the threads on both sides of the outer wall of the stud 20 are symmetrically arranged, the two sliders 21 threadedly sleeved on the outer wall of the stud 20 will move away from each other. The two sliders 21 can drive the respective connected rotating shafts 32, gears 33, torsion springs 31, connecting blocks 22, and saw plates 23 to move together, that is, the two saw plates 23 will also move away from each other. When the two saw plates 23 move away from each other to a certain distance between them, at this time, the two gears 33 will move away from each other until they respectively contact the two toothed plates 34. Then, the two gears 33 will rotate accordingly, and the rotation directions are opposite. Then, the two rotating shafts 32 will also rotate in opposite directions and twist the corresponding torsion springs 31. Then, the two connecting blocks 22 and the two saw plates 23 will rotate in opposite directions (it should be noted that at this time, since the two saw plates 23 have moved away from each other for a certain distance, the distance between the two saw plates 23 can satisfy the rotation in opposite directions between the two saw plates 23). Then, the two saw plates 23 will not only rotate in opposite directions but also move away from each other until the two saw plates 23 are respectively pressed against the corresponding two diagonal braces 5. At this time, the two saw plates 23 are respectively parallel to the two diagonal braces 5, and the saw cut of the dry feed bag will be torn open, and the dry feed bag will also be clamped by the two saw plates 23 on the corresponding diagonal braces 5, thereby fixing the dry feed bag to a certain extent (to prevent the bag body from falling). At this time, the material in the dry feed bag will fall into the mixing tank 3 quickly and in large amounts along the torn opening. Similarly, the materials in the vitamin bag and amino acid bag also fall into the mixing tank 3 in the above manner.

[0047] Next, the driving mechanism is used to drive the rotating column 10 to rotate together with multiple stirring blades 12 (the multiple stirring blades 12 can continuously stir the three kinds of materials and water to achieve premixing). The rotating column 10 can also drive multiple square blocks 36 and multiple connecting plates 6 to rotate. The multiple connecting plates 6 can drive the two diagonal bracing plates 5 connected to each of them to rotate. Then, the vitamin bag, amino acid bag, and dry feed bag will rotate accordingly, so as to evenly put the three kinds of materials into the mixing tank 3. And there will be corresponding diagonal bracing plates 5 to push the saw plates 23 that fit them to rotate together. The saw plates 23 are connected to the concave plates 25 through a series of corresponding structures. Then, the concave plates 25 will drive the support plates 15 and the electric push rods 14 to rotate. The electric push rods 14 will drive the bearing rings 11 to rotate on the outer wall of the mixing tank 3 until the materials in the vitamin bag, amino acid bag, and dry feed bag are almost emptied. At this time, there will still be residual materials in the vitamin bag, amino acid bag, and dry feed bag. At this time, under the above principle, the two sliders 21, two rotating shafts 32, two gears 33, two torsion springs 31, two connecting blocks 22, and two saw plates 23 corresponding to the dry feed bag can be driven to return to their positions in the reverse operation. Then, under the action of the two torsion springs 31, the two saw plates 23 will rotate in the opposite direction to the previous one and move closer to each other until they fit together again. At this time, the dry feed bag can be loosened and the staff can pat or shake the dry feed bag to let the residual materials in it fall into the mixing tank 3 (the dry feed bag will be very light at this time and is very easy to take). Similarly, the vitamin bag and amino acid bag are also like this to let the residual materials in them fall into the mixing tank 3, and it is convenient to perform bag-breaking treatment on the next vitamin bag, amino acid bag, and dry feed bag.

[0048] It should be noted that the bearing ring 11 is not only rotatably sleeved on the outer wall of the mixing tank 3, but also has a strong damping effect, that is, the bearing ring 11 will immediately stop rotating after rotating on the outer wall of the mixing tank 3, and without external force, the bearing ring 11 will not rotate. Only when the rotating column 10 drives the multiple square blocks 36 to rotate, the multiple square blocks 36 drive the connecting plates 6 connected to each of them to rotate, the multiple connecting plates 6 drive the two diagonal bracing plates 5 connected to each of them to rotate, the corresponding diagonal bracing plates 5 drive the corresponding saw plates 23 to rotate, and drive the electric push rods 14 to rotate, will the bearing ring 11 be driven to rotate on the outer wall of the mixing tank 3.

[0049] It should also be noted that when preparing the liquid feed in the premix, an appropriate amount of water is first added to the mixing tank 3. Subsequently, the vitamin bag, amino acid bag, and dry feed bag can be evenly distributed and erected above the mixing tank 3. Moreover, the long sides of the vitamin bag, amino acid bag, and dry feed bag will be punctured, sawn, and torn in sequence, and the bag bodies will also be fixed. In addition, the vitamin bag, amino acid bag, and dry feed bag will rotate around the center of the mixing tank 3. In this way, not only can the three kinds of materials be evenly and quickly scattered into the mixing tank 3 and premixed with water, but also there is no need for workers to frequently unpack and lift the bags, saving time and effort, thus improving the efficiency and quality of the liquid feed premix.

[0050] It should be noted that in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
