Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically a twin-shaft mixing device for feed production. Background Technology

[0002] The twin-shaft mixer is a material mixing equipment widely used in industries such as feed, chemicals, and coatings. Its core function is to achieve efficient mixing of powders, dry powders, and other materials through a twin-shaft design. The twin-shaft mixer plays an important role in feed processing production lines, with a short mixing cycle, generally achieving the required mixing uniformity in 40-60 seconds. This equipment is developed and manufactured by several high-tech enterprises and features a short mixing cycle (generally achieving the required mixing uniformity in 40-60 seconds), small footprint, and simple operation. In fields such as feed processing, dry powder mortar preparation, and solid waste resource treatment, the twin-shaft mixer ensures material quality by optimizing the feeding sequence and controlling the mixing time, and is also equipped with an after-sales service guarantee system.

[0003] In the processing of biaxial mixing equipment, the rotating positions of the two shafts are fixed, so the mixing trajectory is fixed. Although the mixing speed is relatively fast, the finished product may be unevenly mixed. It is usually impossible to complete the mixing completely and evenly in one go. In order to effectively improve the mixing efficiency, we propose a biaxial mixing equipment for feed production. Utility Model Content

[0012] 1.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a dual-shaft mixing device for feed production, including a mixing tank 1. Rotating discs 2 are movably mounted inside the front and rear ends of the mixing tank 1. A rotating shaft 3 is movably supported between the two rotating discs 2. During the rotation of the rotating shaft 3, a spiral blade 4 will be driven to rotate. The raw materials will be mixed and stirred during the rotation of the spiral blade 4. At the same time, the rotating shaft 3 will drive the spiral blade 4 to rotate around the center of the rotating disc 2 for efficient mixing. The spiral blade 4 is fixedly mounted on the outside of the rotating shaft 3. A drive gear 5 is movably supported behind the rear of the rotating disc 2. A driven wheel 6 is fixedly connected to the rear end of the rotating shaft 3.

[0021] A support sleeve 7 is fixedly installed at the rear end of the mixing box 1. A drive motor 8 is fixedly connected to the rear of the support sleeve 7. When the drive motor 8 is started, the output shaft of the drive motor 8 drives the drive gear 5 to rotate. During the rotation of the drive gear 5, the driven wheel 6 rotates, and the driven wheel 6 rotates on its own.

[0022] A discharge sleeve 9 is fixedly installed at the bottom of the mixing box 1. A telescopic column 10 is fixedly connected to the bottom surface of the discharge sleeve 9. A sealing block 11 is fixedly connected above the output shaft of the telescopic column 10. By controlling the output shaft of the telescopic column 10 to retract, the output shaft of the telescopic column 10 drives the sealing block 11 to move downward, so that the side wall of the sealing block 11 moves to the discharge port opened on the outside of the discharge sleeve 9 for material discharge.

[0023] The driving gear 5 and the driven gear 6 are located inside the support sleeve 7, and the external parts of the driving gear 5 and the driven gear 6 mesh with each other. The output shaft of the drive motor 8 is fixedly connected to the rear axis of the driving gear 5.

[0024] A gear ring is provided on the inner side of the support sleeve 7, and the outer side of the driven wheel 6 is supported on the inner side of the gear ring.

[0025] A discharge groove is provided on the outer side of the discharge sleeve 9, and a guide plate 12 is fixedly installed on the outside of the discharge sleeve 9. The guide plate 12 is located below the discharge groove.

[0026] In summary, this dual-shaft mixing equipment for feed production operates as follows: First, the raw materials to be mixed are filled into the mixing tank 1 from above. Then, the raw materials fall into the inner cavity of the mixing tank 1. Next, the drive motor 8 is started, and its output shaft drives the drive gear 5 to rotate. During the rotation of the drive gear 5, the driven wheel 6 rotates, and the driven wheel 6 rotates on its own axis. Subsequently, the driven wheel 6 drives the rotating shaft 3 to rotate, which in turn drives the spiral blade 4 to rotate. The rotation of the spiral blade 4 mixes and stirs the raw materials. At the same time, the rotating shaft 3 drives the spiral blade 4 to rotate around the center of the rotating disk 2 for efficient mixing. After mixing is complete, the output shaft of the telescopic column 10 is retracted, causing the output shaft of the telescopic column 10 to move the sealing block 11 downward. The side wall of the sealing block 11 moves to below the discharge port on the outside of the discharge sleeve 9 for discharge.
