Description

Technical Field

[0001] This utility model relates to the field of mixing equipment, specifically to a gradient mixing device for chicken feed based on pre-activated solid trace elements. Background Technology

[0002] In the current poultry industry, pre-activated solid trace elements are widely used in chicken feed formulation because they can improve chicken immunity and egg quality. However, these trace elements have fine particles, are prone to absorbing moisture and clumping, and their activity is easily affected by vigorous stirring and high temperatures, making it difficult for conventional mixing equipment to adapt to their characteristics.

[0003] Existing chicken feed mixing equipment mostly uses a single stirring mode, which not only fails to pre-activate trace element additives but also easily leads to uneven dispersion, resulting in localized over- or under-dispersion. Furthermore, vigorous stirring can damage the activity of trace elements, affecting the quality of subsequent feed. These problems lead to nutritional imbalances in feed, hindering the improvement of poultry farming efficiency, and urgently require specialized gradient mixing devices to solve these pain points.

[0004] Based on this, the present utility model is proposed. Utility Model Content

[0032] like Figures 1-5 As shown, the gradient mixing device for chicken feed based on pre-activated solid trace elements includes: a top plate 1, a feed inlet 2, a pre-activation section, a first mixing chamber 8, a first motor 9, a second mixing chamber 10, a third mixing chamber 11, a rotating column 13, a mixing plate 15, a speed change mechanism, a base 21, a support leg 22, a feed cylinder 23, a valve 24, a chute 25, an opening and closing plate 26, and a pull rod 27.

[0033] A feed inlet 2 is installed on the top plate 1. A pre-activation section is installed at the top of the top plate 1. The first mixing chamber 8, the second mixing chamber 10, and the third mixing chamber 11 are installed sequentially from top to bottom at the bottom of the top plate 1. Several extension plates 12 are installed on the first mixing chamber 8, the second mixing chamber 10, and the third mixing chamber 11. Adjacent extension plates 12 on the first mixing chamber 8, the second mixing chamber 10, and the third mixing chamber 11 are connected by bolts to ensure that the first mixing chamber 8, the second mixing chamber 10, and the third mixing chamber 11 form a stable whole. Circular outlets for discharging material are respectively opened at eccentric positions on the lower surfaces of the first mixing chamber 8, the second mixing chamber 10, and the third mixing chamber 11. The feed inlet 2 is used to convey material into the first mixing chamber 8. A base 21 is installed at the bottom of the third mixing chamber 11, and support legs 22 are installed at the bottom of the base 21. The base 21 and the support legs 22 together constitute a stable support device for supporting the entire device. The feeding cylinder 23 is installed on the lower surface of the third mixing chamber 11 and connected to the outlet of the lower surface of the third mixing chamber 11 for discharging the material in the third mixing chamber 11. A valve 24 is installed on the feeding cylinder 23; this valve 24 is an electric valve that can control the opening and closing of the feeding cylinder 23 as needed.

[0034] The pre-activation section includes: an assembly frame 3, a rotating frame 4, a second motor 5, a ball mill drum 6, and a cylinder 7. The assembly frame 3 is mounted on the upper surface of the top plate 1. The rotating frame 4 is mounted on the top plate 1, with one end rotatably connected to the assembly frame 3. The second motor 5 is mounted on the rotating frame 4. The ball mill drum 6 is rotatably mounted inside the rotating frame 4 and connected to the output end of the second motor 5. The ball mill drum 6 has a filling port, and abrasive is filled inside. Trace element raw materials are then added to the ball mill drum 6 through the filling port. Turning on the second motor 5 drives the ball mill drum 6 to rotate, using the abrasive to grind the trace element raw materials, resulting in uniform grinding. One end of the cylinder 7 is rotatably mounted on the top plate 1, and the other end is rotatably connected to the rotating frame 4. The end of the ball mill drum 6 furthest from the second motor 5 is connected to the first mixing chamber 8 via a connecting pipe. A filter screen is provided at the end of the connecting pipe connected to the ball mill drum 6, ensuring that only ground material meeting the particle size requirements enters the connecting pipe. Opening cylinder 7 can drive rotating frame 4 to rotate ball mill drum 6, thereby pouring out the material in ball mill drum 6 that meets the particle size requirements.

[0035] Three rotating columns 13 are respectively rotatably installed in the first mixing chamber 8, the second mixing chamber 10, and the third mixing chamber 11. Mixing plates 15 are installed on the side wall of the rotating columns 13. There are two mixing plates 15, one long and one short. When the rotating columns 13 rotate, they drive the mixing plates 15 to rotate, agitating and mixing the materials in their respective chambers. The different lengths of the two mixing plates 15 increase the degree of mixing disorder and prevent the formation of vortices. A speed-changing mechanism is connected to the rotating columns 13, and through the linkage of the speed-changing mechanism, the rotational speed of the upper and lower rotating columns 13 can be changed. Furthermore, a keyway 14 is provided at the top of the rotating columns 13.

[0036] There are two speed-changing mechanisms, respectively located at the connection between the first mixing chamber 8 and the second mixing chamber 10, and at the connection between the second mixing chamber 10 and the third mixing chamber 11. Each speed-changing mechanism includes a gear ring plate 16, a mounting bracket 17, a first gear 18, a second gear 19, and a spline 20. The gear ring plate 16 is connected to the bottom end of the rotating column 13, and the two can rotate synchronously. The gear ring plate 16 has one ring of internal teeth. The mounting bracket 17 is coaxially arranged with the rotating column 13, and each mounting bracket 17 in the two speed-changing mechanisms is fixedly connected to the inner wall of the second mixing chamber 10 or the third mixing chamber 11, respectively. The first gear 18 is rotatably mounted on the mounting bracket 17 in an eccentric position and meshes with the gear ring plate 16. The rotation of the gear ring plate 16, through meshing linkage, enables the first gear 18 to rotate. The second gear 19 is rotatably mounted at the center position of the mounting bracket 17 and meshes with the first gear 18 to achieve a transmission relationship. The spline 20 is mounted on the bottom end of the second gear 19 and rotates synchronously with the second gear 19. The spline 20 and the keyway 14 are shaped to fit together and can form a synchronous rotational connection after insertion. The first motor 9 is installed at the center of the top plate 1, and the output end of the first motor 9 is connected to the keyway 14 at the top, which can drive the rotating column 13 in the first mixing chamber 8 to rotate.

[0037] The second mixing chamber 10 and the third mixing chamber 11 are respectively provided with sliding grooves 25. Opening and closing plates 26 are rotatably mounted on the lower surfaces of the first mixing chamber 8 and the second mixing chamber 10. The shape and position of the opening and closing plates 26 correspond to the outlets on the lower surfaces of the first mixing chamber 8 and the second mixing chamber 10. Rotation allows the outlets to be opened and closed, releasing the material. A pull rod 27 is formed at one end of the opening and closing plate 26 facing the sliding groove 25, and the pull rod 27 extends out of the sliding groove 25. The pull rod 27 is L-shaped for easy pushing and pulling. In this embodiment, a damping shaft is used at the rotatable connection of the opening and closing plate 26, providing resistance during rotation and preventing arbitrary rotation when not in use.

[0038] In operation, the equipment initially blocks the corresponding outlets with each of the opening and closing plates 26. First, lignite powder is mixed with lignin and other materials, then a solid oxidant and MOF derivative catalyst are added. The mixture is then fed into the ball mill through the filling port at the top of the rotating drum 6 for ball milling. The mechanical force of the ball milling process breaks down the mineral structure, while the catalyst accelerates the transformation of trace elements, thus performing pre-activation treatment. The final product has high trace element activity and achieves a slow-release effect, extending the action time, and ultimately allows the product to enter the first mixing chamber 8. Subsequently, all remaining raw materials for chicken feed are fed into the first mixing chamber 8 through the feed inlet 2. The first motor 9 is activated, driving the connected rotating column 13 to rotate. The materials in the first mixing chamber 8 are initially mixed under the action of the mixing plate 15. Then, the upper lever 27 is pulled, causing the opening and closing plate 26 to rotate and open the outlet. With the rotation of the mixing plate 15, the materials finally fall through the outlet into the second mixing chamber 10. Simultaneously, the rotation of the rotating column 13 in the first mixing chamber 8, through the rotation of the toothed ring plate 16 connected to it, drives the corresponding first gear 18 and second gear 19 to rotate synchronously. Since the diameter of the second gear 19 is smaller than the inner diameter of the toothed ring plate 16, the second gear 19 will eventually drive the spline 20 to rotate, and the speed will be increased, thereby driving the rotating column 13 in the second mixing chamber 10 to rotate faster, so that the material is further mixed. Controlling the corresponding opening and closing plate 26 can allow the material in the second mixing chamber 10 to enter the third mixing chamber 11, and through the same speed change mechanism, the mixing speed in the third mixing chamber 11 is further increased. This equipment can achieve the pre-activation of solid trace elements and has three mixing gradients, which can ensure the thorough mixing of feed materials and avoid the deactivation of effective components in the feed due to direct high-speed mixing.

[0039] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
