Description

Technical Field

[0001] This utility model relates to the field of material mixing equipment technology, and in particular to a high-efficiency mixing device for silkworm feed. Background Technology

[0002] In modern large-scale sericulture, silkworms are generally fed with formulated compound silkworm feed, rather than the traditional single mulberry leaf feed, to reduce costs and increase productivity. Current silkworm feed formulations typically include mulberry leaf powder, soybean meal powder, starch, agar, and yeast powder. Therefore, mixing equipment is required during compound preparation. Since silkworm feed is mostly composed of powdery substances with a certain degree of viscosity, conventional mixers are not effective at mixing such mixtures. In conventional mixers, the mixing tank (container) remains stationary; only the mixing shaft drives the mixing blades. This single mixing action results in poor mixing efficiency (uneven mixing, and materials easily clumping against the inner wall of the tank). Furthermore, discharging the feed after mixing is inconvenient, requiring manual scooping using a scoop from a horizontally cut outlet on the side of the tank. This is not only difficult to remove completely but also labor-intensive and time-consuming, reducing efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a high-efficiency mixing device for silkworm feed, so as to overcome the shortcomings and defects of the existing technology and products as described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a high-efficiency mixing device for silkworm feed, including a frame, a tank, a mixing shaft, and a reduction drive motor. The tank is ellipsoidal, with mixing shaft insertion holes at both axial ends and a shaft tube. Each shaft tube is supported and positioned by a bearing I fixedly mounted on the frame. The tank is horizontally and rotatably mounted on the frame. A sealed inlet / outlet is provided in the middle of the tank. The mixing shaft enters the tank horizontally through the mixing shaft insertion hole via the shaft tube and is supported by a bearing II installed inside the shaft tube. A sealing ring is provided between the hole wall of the mixing shaft insertion hole and the shaft wall of the mixing shaft. Multiple sets of mixing rods are spaced apart on the mixing shaft, and multiple mixing rods extending into the inner cavity of the tank are also provided on the inner wall of the tank. One end of the mixing shaft is connected to the output shaft of the reduction drive motor mounted on the frame via a sprocket and chain drive. A drive gear is installed on the output shaft of the reduction drive motor, and a corresponding gear ring is coaxially provided on the outer wall of the tank. The drive gear meshes with the gear ring.

[0005] Furthermore, each stirring rod has a stirring ring formed at its end.

[0006] Furthermore, a feeding hopper is also installed on the frame, which is located directly above the tank. When the tank's inlet / outlet is facing upwards, it is directly opposite the feeding port of the feeding hopper.

[0007] The beneficial effects of this utility model are as follows: During operation, the efficient silkworm feed mixing device features a mixing shaft that rotates simultaneously in opposite directions with the tank body, and the mixing rods alternately agitate the feed, thus greatly enhancing the mixing effect. Furthermore, the rotation of the tank body causes the feed to tumble up and down within the tank, which, combined with the agitation of the mixing rods, results in an excellent mixing effect. For discharging, simply rotate the tank body to a position where the inlet / outlet faces downwards, open the inlet / outlet caps, and the feed will automatically fall due to gravity, making it convenient and efficient.

[0013] A high-efficiency mixing device for silkworm feed, such as Figures 1 to 3 As shown, it includes a frame 1, a tank 2, a stirring shaft 3, and a reduction drive motor 4. The tank 2 is ellipsoidal, with stirring shaft insertion holes at both axial ends and a shaft tube 2-1. Each shaft tube 2-1 is supported and positioned by a bearing I 5 fixedly mounted on the frame 1. The tank 2 is horizontally and rotatably mounted on the frame 1. A sealed inlet / outlet 2-2 is provided in the middle of the tank 2. The stirring shaft 3 enters the tank 2 horizontally through the stirring shaft insertion hole via the shaft tube 2-1 and is supported by a bearing II 6 installed inside the shaft tube 2-1. A sealing ring 7 is provided between the hole wall of the stirring shaft insertion hole and the shaft wall of the stirring shaft 3. Multiple sets of stirring rods 10 are spaced apart on the stirring shaft 3, and multiple stirring rods 10 extending into the inner cavity of the tank 2 are also provided on the inner wall of the tank 2.

[0014] One end of the stirring shaft 3 is connected to the output shaft of the geared drive motor 4 mounted on the frame 1 via a sprocket and chain drive. At the same time, a drive gear 8 is mounted on the output shaft of the geared drive motor 4, and a corresponding gear ring 9 is coaxially arranged on the outer wall of the tank 2. The drive gear 8 meshes with the gear ring 9.

[0015] During operation, this high-efficiency silkworm feed mixing device features a mixing shaft 3 that rotates simultaneously in opposite directions with the tank body 2. The mixing rods 10 alternately agitate the feed, significantly enhancing the mixing effect. Furthermore, the rotation of the tank body 2 causes the feed to tumble and roll within it, which, combined with the agitation of the mixing rods 10, results in excellent mixing performance. For discharge, simply rotate the tank body 2 until its inlet / outlet 2-2 faces downwards, open the cover of the inlet / outlet 2-2, and the feed will automatically fall due to gravity – convenient and efficient.

[0016] To further enhance the mixing effect, a mixing ring 10-1 is formed at the end of each mixing rod 10.

[0017] To facilitate material feeding into the tank 2, a feeding hopper 11 is also installed on the frame 1. The feeding hopper 11 is located directly above the tank 2, and when the inlet / outlet 2-2 of the tank 2 is facing upwards, it is directly opposite the discharge port of the feeding hopper 11. When feeding is required, the tank 2 is rotated to the position where its inlet / outlet 2-2 is facing upwards by operating the reduction drive motor 4, and then the material can be fed into the tank 2 through the feeding hopper 11. After feeding is completed, the cover of the inlet / outlet 2-2 is closed.

[0018] The above embodiments are only used to explain the present utility model and are not intended to limit the protection of the present utility model. Any non-substantial modifications made based on the essential solution of the present utility model shall fall within the protection scope of the present utility model.
