Description

Technical Field

[0001] The utility model relates to the field of horizontal mixers, and more specifically, to a horizontal double-screw feed mixing mixer. Background Art

[0002] The small mixed ration feed mixer is designed according to the nutritional needs of livestock and poultry such as cattle and sheep in different growth and development stages. It mixes and processes roughage, green fodder and concentrate in proportion according to the designed ration formula for different stages to form a mixed feed with relatively balanced nutrition.

[0003] CN205799845U discloses a forced horizontal mixer, which includes a frame, a horizontal mixing tank mounted on the frame, a sealing cover provided on the top of the horizontal mixing tank, a feed port provided on the sealing cover, a horizontally arranged mixing shaft provided in the horizontal mixing tank, a double-helix mixing blade installed on the mixing shaft, a mixing motor provided at the rear of the horizontal mixing tank, the mixing motor connected to the mixing shaft via a coupling, and a discharge door panel provided on the front lower side of the horizontal mixing tank.

[0004] The existing mixers have the following problems during use: 1. The existing discharge port is located on one side of the mixing tank body. The single-sided discharge causes uneven mixing and inconvenience in discharging. In order to fully discharge the material, a dumping device is often provided, which increases the complexity of the device; 2. The mixing blades repeatedly collide during the mixing process, causing deformation when mixing hard feed, reducing the mixing effect, and causing imbalance in the mixing shaft. The vibration and noise during the mixing process increase and affect the service life of the motor; 3. The mixing tank body is mostly cylindrical, and the feed is easily retained at the bottom seam, which is difficult to clean. Over time, it will cause corruption and affect the health of livestock and poultry. Utility Model Content
