Description

Technical Field

[0001] This invention relates to the field of feed processing technology, specifically to a liquid feed premix mixing device. Background Technology

[0002] Liquid feed refers to feed that is premixed with water or some liquid food industry by-products in a certain proportion, and then stabilized through fermentation or non-fermentation methods. Compared with solid feed, liquid feed has advantages in reducing production costs and improving the growth performance of suckling piglets and weaned piglets.

[0003] In the process of preparing liquid feed, vitamins and amino acids are added to enhance nutritional content. Vitamins, amino acids, dry feed, and water are premixed together in a mixing tank. When producing large quantities of liquid feed, the amounts of vitamins, amino acids, and dry feed added to the mixing tank also increase. However, in livestock farms, vitamins, amino acids, and dry feed are often purchased in bags, which means frequent bag opening is necessary. Furthermore, the mixing tank itself is quite tall, requiring workers to hold the feed bags up and pour them out for a period of time. This is not only time-consuming and labor-intensive, but also results in uneven distribution of feed, tending to concentrate at the bottom of the tank, which affects the efficiency and quality of the liquid feed premix. Therefore, we propose a liquid feed premix mixing device. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides a technical solution: such as Figure 1 - Figure 7 The liquid feed premix mixing device shown includes a mixing tank 3, a discharge assembly at the bottom of the mixing tank 3, a rotating column 10 rotatably mounted at the center of the mixing tank 3 via a drive mechanism, a bearing ring 11 rotatably mounted on the outer wall of the mixing tank 3, multiple stirring blades 12 fixedly connected to the outer wall of the rotating column 10, and multiple square blocks 36 (e.g., ...) fixedly connected to the upper edge of the outer wall of the rotating column 10. Figure 7 As shown), a feeding mechanism is provided between each of the multiple 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 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. The wall surface of the connecting plate 6 away from the block 36 is symmetrically and fixedly connected with inclined bracing plates 5. A support assembly is provided between the two inclined bracing plates 5 and the mixing tank 3. Two closely fitting saw blades 23 are provided between the two inclined bracing plates 5. A repositioning mechanism is provided between the two saw blades 23 and the electric push rod 14.

[0030] The discharge assembly includes a discharge pipe 2, which is connected to the bottom of the mixing tank 3, and a valve 1 is installed on the discharge pipe 2.

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

[0032] The drive mechanism includes three support frames 4. One end of each support frame 4 is fixedly connected to the outer wall of the mixing tank 3. The other ends of the three support frames 4 are all fixedly connected to a triangular block 8. 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 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 will drive the rotating column 10 to rotate slowly.

[0034] The support assembly includes a support ring 9, which is slidably embedded in the inner wall of the mixing tank 3 near the upper edge. The inner ring surface of the support ring 9 and the wall surfaces of the two diagonal bracing plates 5 that are far apart from each other are fixedly connected with splicing rods 24.

[0035] Specifically, when multiple inclined support plates 5 are driven to rotate, each inclined support plate 5 will drive its connected splicing rod 24 to rotate together. The multiple splicing rods 24 will drive the support ring 9 to rotate against the inner wall of the mixing tank 3, which will not cause motion interference, but will also provide a stable support for the inclined support plate 5 and add a force point.

[0036] The repositioning mechanism includes a support plate 15, which 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 guide assembly and a reciprocating drive assembly are respectively provided between the concave plate 25 and the support plate 15. A stud 20 and a limiting post 29 are rotatably connected between the two inner vertical walls of the concave plate 25. A transmission assembly is provided at one end of the stud 20. The threads on both sides of the outer wall of the stud 20 are symmetrically arranged. A slider 21 is threaded onto both sides of the outer wall of the stud 20. The limiting post 29 movably passes through the two sliders 21. A rotating shaft 32 is rotatably connected to one end of each slider 21 corresponding to the mixing tank 3. A connecting block 22 is fixedly connected to the end of each rotating shaft 32 away from the slider 21. The corresponding wall surfaces of the two connecting blocks 22 are fixedly connected to the wall surfaces of the two saw blades 23 that are far from each other. A linkage assembly is provided between the two rotating shafts 32 and the concave plate 25.

[0037] The guide assembly includes two guide posts 30, which are slidably inserted into two vertical walls of the concave plate 25. The two guide posts 30 are close to the upper end of the support plate 15. Both ends of the two guide posts 30 are fixedly connected to fixing blocks 28, and 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 guide posts 30 and fixing 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, thereby improving the stability of the concave plate 25.

[0039] The reciprocating drive assembly includes a 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 frame 16. A turntable 18 is fixedly connected to the output shaft end of the second motor 17. A connecting rod 13 is rotatably connected to the wall of the turntable 18 away from the second motor 17. A splicing plate 26 is rotatably connected to the end of the connecting rod 13 away from the turntable 18. The wall 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 walls of the concave plate 25. A motor 3 19 is fixedly installed at the upper end of the support block 27. The output shaft of the motor 3 19 movably passes through the vertical wall of the concave plate 25, and the output shaft end of the motor 3 19 is fixedly connected to one end of the stud 20.

[0041] Specifically, starting motor 319 will drive 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 the two rotating shafts 32. Each of the two gears 33 is fixedly connected to a torsion spring 31 between it and the two sliders 21. 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. The ends of the two toothed plates 34 away from the L-shaped plates 35 are 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 blades 23 are all rounded.

[0044] Specifically, the bottom ends of both connecting blocks 22 are curved surfaces, which makes it less likely for the bottom ends of the two connecting blocks 22 to come into contact with each other and cause motion interference when they rotate in opposite directions. Similarly, the two saw blades 23 are also like this. At the same time, the two connecting blocks 22 are not obstructed by the upper surface of the mixing tank 3 when they rotate in opposite directions.

[0045] Working principle: First, add an appropriate amount of water to the mixing tank 3. Then, insert the vitamin bag, amino acid bag, and dry feed bag along their long sides between the two inclined support plates 5 connected to the multiple connecting plates 6. The vitamin bag, amino acid bag, and dry feed bag will then be secured between the corresponding two inclined support plates 5. Adjust the bags to be upright. Next, start the electric push rod 14 for the corresponding dry feed bag. The electric push rod 14 drives the corresponding support plate 15, two closely fitting saw blades 23, and other structures connected to the support plate 15 and the two saw blades 23 to move upwards. The two saw blades 23 can first pierce the long side of the dry feed bag upwards, and then the two saw blades 23 extend into... A small portion of the feed is poured into the dry feed bag. Then, motor 17 is started. Motor 17 drives turntable 18 to rotate. Turntable 18 drives connecting rod 13 to swing back and forth with a small amplitude. Then connecting rod 13 drives splicing plate 26 and concave plate 25 to move back and forth a short distance together. Concave plate 25 drives stud 20, limit post 29, two sliders 21, two rotating shafts 32, two gears 33, two torsion springs 31, two connecting blocks 22 and two saw blades 23 to move back and forth a short distance together. Then the two saw blades 23 can cut the long side of the dry feed bag. At this time, a small amount of material in the dry feed bag can fall into the mixing tank 3 along the cut.

[0046] Subsequently, the transmission assembly drives the stud 20 corresponding to the dry feed bag to rotate. Because the threads on both sides of the stud 20's outer wall are symmetrically arranged, the two sliders 21 threaded onto the outer wall of the stud 20 will move away from each other. The two sliders 21 can drive their respective connected rotating shafts 32, gears 33, torsion springs 31, connecting blocks 22, and saw blades 23 to move together. That is, the two saw blades 23 will also move away from each other. When the two saw blades 23 move away from each other to a certain distance, the two gears 33 will move away from each other until they contact the two toothed plates 34 respectively. Then, the two gears 33 will rotate accordingly, but in opposite directions. The two rotating shafts 32 will also rotate in opposite directions and twist the corresponding torsion springs 31. Therefore, the two connecting blocks 22 and the two saw blades 23 will rotate in opposite directions. (It should be noted that since the two saw blades 23 have moved away from each other by a certain distance, the distance between the two saw blades 23 can satisfy the opposite rotation of the two saw blades 23.) Then the two saw blades 23 will not only rotate in opposite directions but also move away from each other until the two saw blades 23 are respectively attached to the two corresponding inclined support plates 5. At this time, the two saw blades 23 are parallel to the two inclined support plates 5, and the saw cut of the dry feed bag will be torn open. The dry feed bag will also be clamped by the two saw blades 23 to the corresponding inclined support plates 5, thereby fixing the dry feed bag to a certain extent (to prevent the bag from falling). At this time, the material in the dry feed bag will fall into the mixing tank 3 in large quantities and quickly along the tear. Similarly, the material in the vitamin bag and amino acid bag will fall into the mixing tank 3 in the same way as described above.

[0047] Next, the drive mechanism drives the rotating column 10 and multiple stirring blades 12 to rotate together (the multiple stirring blades 12 can continuously stir the three materials and water to achieve premixing). The rotating column 10 can also drive multiple blocks 36 and multiple connecting plates 6 to rotate together. The multiple connecting plates 6 can drive the two inclined support plates 5 connected to them to rotate together. Then the vitamin bag, amino acid bag and dry feed bag will rotate accordingly, so that the three materials are evenly put into the mixing tank 3. And the corresponding inclined support plate 5 will push the saw blade 23 that is attached to it to rotate together. The saw blade 23 is connected to the concave plate 25 through a series of corresponding structures. Then the concave plate 25 will drive the support plate 15 and the electric push rod 14 to rotate together. The electric push rod 14 will drive the bearing ring 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 as much as possible. At this point, there will still be residual material in the vitamin bag, amino acid bag, and dry feed bag. 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 blades 23 corresponding to the dry feed bag can be driven back to their original positions by reversing the operation. Then, under the action of the two torsion springs 31, the two saw blades 23 will move in the opposite direction to the previous rotation and move closer to each other until they are pressed together again. At this time, the dry feed bag can be loosened and the worker can pat or shake the dry feed bag to let the residual material inside fall into the mixing tank 3 (the dry feed bag will be very light at this time and very easy to pick up). Similarly, the vitamin bag and amino acid bag will also let the residual material inside fall into the mixing tank 3, and it is convenient to break the next vitamin bag, amino acid bag, and dry feed bag.

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

[0049] It should also be noted that when premixing liquid feed, an appropriate amount of water is first added to mixing tank 3. Then, the vitamin bags, amino acid bags, and dry feed bags can be evenly distributed and placed above mixing tank 3. The long sides of the vitamin bags, amino acid bags, and dry feed bags will be punctured, sawed, and torn in sequence, and the bags will be fixed in place. The vitamin bags, amino acid bags, and dry feed bags will also rotate around the center of mixing tank 3. This not only allows the three materials to be evenly and quickly sprinkled into mixing tank 3 and premixed with water, but also eliminates the need for workers to frequently open and lift the bags, saving time and effort, thereby improving the efficiency and quality of liquid feed premix.
