Abstract
Description
Technical Field
[0001] This utility model relates to a mixing device for Chinese herbal feed additives for ducks, belonging to the field of mixing technology. Background Technology
[0002] Traditional Chinese medicine (TCM) feed additives can not only effectively enhance the immunity and improve the growth of laying ducks, but also improve egg quality, meeting consumers' demand for green and safe poultry products. However, the full effectiveness of TCM feed additives in practical applications largely depends on their uniform mixing with the base feed. Traditional mixing methods often involve manual or mechanical stirring.
[0003] Traditional mechanical mixers have many drawbacks during use: 1. Traditional mixers are prone to causing gravity stratification or uneven axial mixing when mixing materials with large differences in specific gravity and particle size, such as Chinese medicine powder and feed carrier, resulting in poor mixing uniformity and affecting the breeding effect.
[0004] 2. When additives enter the mixer, they tend to accumulate near the discharge point, resulting in uneven initial distribution and increasing the difficulty and time of subsequent mixing.
[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0006] This invention addresses the shortcomings of the prior art by providing a mixing device for Chinese herbal feed additives for laying ducks. It can solve the stratification phenomenon caused by density differences, ensure that the mixture is highly uniform in both the vertical and horizontal directions, and solve the problem of uneven initial distribution of feed, thus achieving efficient mixing.
[0007] To solve the above technical problems, the present invention adopts the following technical solution: A mixing device for traditional Chinese medicine feed additives for laying ducks includes a mixing silo, with multiple feeding silos surrounding it. The bottom of each feeding silo is connected to the inner cavity of the mixing silo via a horizontally positioned feeding cylinder. A vertically positioned main shaft is installed inside the mixing silo, with stirring blades fixedly installed at the bottom. A hollow shaft geared motor passes through the top of the main shaft and is connected to a worm gear screw jack via a connector. The hollow shaft geared motor is fixedly connected to the top of the mixing silo, and the worm gear screw jack is fixedly connected above the hollow shaft geared motor via a longitudinal support rod. The feeding port of the feeding cylinder is located near the main shaft, and a feeding plate is fixedly installed on the main shaft body, located below the feeding port.
[0008] Furthermore, a bushing is fitted onto the main body of the spindle, and the bushing is fixed to the center of the mixing chamber by a plurality of circumferentially distributed transverse support rods.
[0009] Furthermore, the feeding end of the feeding cylinder is inserted into the wall of the mixing silo.
[0010] Furthermore, a screw is inserted inside the feed cylinder, and one end of the screw is connected to the feed motor via a coupling. The feed motor is fixed to the outer side of the end of the feed cylinder.
[0011] Furthermore, the fabric plate is located above the bushing and the transverse support rod.
[0012] Furthermore, all the feeding bins are installed inside the support frame.
[0013] Furthermore, a weighing sensor is installed at the connection between the feeding hopper and the support.
[0014] Furthermore, the main shaft is connected to the hollow shaft geared motor via a flat key.
[0015] Furthermore, the bottom of the mixing hopper is provided with a discharge port, and a discharge valve is installed on the discharge port.
[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: While the mixing blades rotate at high speed to perform radial mixing, they also move up and down along the entire height of the mixing bin, breaking up the stratification phenomenon caused by the density difference of the materials and ensuring that the mixture is highly uniform in both the vertical and horizontal directions. A material distribution plate is fixedly installed on the main shaft below the feed port. The high-speed rotating material distribution plate acts like a centrifugal spreading disc, instantly breaking up the falling material and evenly spreading it across the entire cross-section of the mixing hopper. This achieves material dispersion upon entering the hopper, avoids local accumulation, and creates uniform starting conditions for subsequent efficient mixing. Weighing sensors can provide real-time weight feedback, which the control system uses to precisely control the start, stop, and running time of each feeding motor, driving the screw to achieve quantitative, continuous, and controllable material conveying.
[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation
[0020] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0021] like Figures 1-4 As shown in the figure, this utility model provides a mixing device for Chinese medicine feed additives for ducks, including a mixing bin 1, and a plurality of feeding bins 10 are arranged around the mixing bin 1. The bottom of the feeding bins 10 is connected to the inner cavity of the mixing bin 1 through a horizontally arranged feeding cylinder 9.
[0022] The mixing silo 1 is equipped with a vertically oriented main shaft 2. The top of the main shaft 2 passes through a hollow shaft reduction motor 4 and is connected to a worm gear screw jack 5 via a connector. The hollow shaft reduction motor 4 is fixed to the top of the mixing silo 1, and the worm gear screw jack 5 is fixed above the hollow shaft reduction motor 4 via a longitudinal support rod 6.
[0023] The main shaft 2 is connected to the hollow shaft geared motor 4 via a key. The hollow shaft geared motor 4 can transmit torque to the main shaft 2, driving it to rotate at high speed. The main shaft 2 can also move up and down inside the hollow shaft geared motor 4. The structure of the worm gear screw jack 5 is existing technology, and the worm gear screw jack 5 provides power for the lifting of the main shaft 2.
[0024] The bottom of the main shaft 2 is fixedly equipped with stirring blades 3 that can move with it.
[0025] A bushing 7 is fitted onto the main body of the main shaft 2. The bushing 7 is fixed to the center of the mixing chamber 1 by multiple circumferentially distributed transverse support rods 8. The fixed bushing 7 provides a rigid guide channel for the lifting and lowering movement of the main shaft 2, ensuring that the rotating shaft 7 moves vertically along a preset axis. It can also provide radial support to resist the lateral force on the rotating shaft 7 and maintain the stability of the movement.
[0026] The feeding end of the feeding cylinder 9 is inserted into the wall of the mixing silo 1. A screw 16 is inserted into the feeding cylinder 9. One end of the screw 16 is connected to the feeding motor 11 through a coupling. The feeding motor 11 is fixed to the outside of the end of the feeding cylinder 9.
[0027] The feed inlet of the feed cylinder 9 is located close to the main shaft 2. A material distribution plate 14 is fixedly installed on the main body of the main shaft 2. The material distribution plate 14 is located below the feed inlet and above the bushing 7 and the transverse support rod 8. The material distribution plate 14 rotates with the main shaft 2, scattering the material entering from the feed inlet to the surrounding area to improve the mixing efficiency.
[0028] All the feeding bins 10 are installed inside the brackets 13, and weighing sensors 12 are installed at the connection between the feeding bins 10 and the brackets 13. The weighing sensors 12 are used to monitor the weight of the material in the feeding bins 10 in real time in order to achieve accurate feeding.
[0029] The bottom of the mixing silo 1 is provided with a discharge port 15, and a discharge valve is installed on the discharge port 15.
[0030] The specific working principle of this utility model is as follows: The control system precisely controls the start, stop, and running time of each feeding motor 11 based on the preset formula ratio and the real-time feedback from the weighing sensor 12. The feeding motor 11 drives the screw 16 to rotate, quantitatively and continuously pushing specific types and weights of additives from the feeding bin 10 into the inner cavity of the mixing bin 1.
[0031] When the material falls into the mixing hopper 1 from the feed port, the high-speed rotating main shaft 2 drives the material distribution plate 14 to rotate together. The rotating material distribution plate 14 is like a centrifugal spreading disc, which instantly disperses the falling material and throws it around the mixing hopper 1, avoiding the accumulation of material at the feed point and making it initially evenly distributed on the cross section of the mixing hopper 1, thus improving the efficiency of subsequent mixing.
[0032] The stirring blades 3 simultaneously rotate at high speed (for horizontal mixing) and move up and down (for vertical mixing). This combined motion allows the stirring blades 3 to cover the entire effective volume of the mixing bin 1, completely breaking the stratification of materials and achieving efficient and uniform mixing.
[0033] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
