DETAILED DESCRIPTION

[0025] In order to better understand the present invention, the following is a detailed description with reference to the accompanying drawings and embodiments.

[0026] Example: Figures 1-4 As shown, a high-efficiency auger for feed mixing trucks includes a tapered shaft 1, on which a spiral blade 2 is wound. The spiral blade 2 includes a starting portion 21 and a spiral portion 22 at the bottom end, and the blade width of the spiral portion 22 gradually decreases from bottom to top. Two points are selected on the edge line of the starting portion 21 of the spiral blade 2, and the edge portion is cut off along the straight line formed by the two points to form a notch 211. The starting portion 21 and the notch 211 portion of the spiral blade 2 are the starting portion 21. The outer edge line of the starting portion 21 includes a curved segment 212 and a straight segment 213 connecting the curved segment and the outer edge line of the spiral portion 22. The angle α formed between the two end points of the straight segment 213 and the center of the tapered shaft 1 is 60-90 degrees. The notch 211 provides sufficient falling space for the feed stirred and transported to the top by the spiral blade 2, so that the feed can fall back to the bottom and be sent into the spiral blade 2 again for secondary stirring, so that the feed can be stirred more quickly and evenly. The provision of the notch 211 also reduces the power required for the auger to rotate, thereby lowering the requirements for the driving device.

[0027] Multiple sets of reamers 3 are installed at intervals along the outer edge of the spiral blade 2. These reamers 3 can cut longer roughage such as grass, facilitating even mixing of the feed. The reamers 3 can be of the same model, or different models can be used in combination. In this embodiment, the reamers 3 include two types: a large triangular reamer 3 and a small, elongated reamer 3. The combination of these two reamers 3 enhances the shearing effect.

[0028] One or more baffle plate brackets 41 are provided near the curved section 212 of the starting portion 21. The baffle plate brackets 41 are inclined to the upper surface of the spiral blade 2. A baffle plate 4 is mounted on the baffle plate brackets 41 via bolts 9. The angle between the upper surface of the baffle plate 4 and the spiral blade 2 is greater than 90 degrees, thereby gathering feed at the edge toward the center of the auger, facilitating rapid and uniform mixing of the feed.

[0029] The lower edge of the spiral blade 2 (i.e. the inlet of the spiral blade 2) is provided with a material shoveling plate 5, the front end of the material shoveling plate 5 is downwardly inclined, the material shoveling plate 5 can deliver the feed on the floor of the feed mixer truck into the spiral blade 2, and can also protect the spiral blade 2. The material shoveling plate 5 is provided with a strip-shaped hole 8, the material shoveling plate 5 is installed on the front end of the spiral blade 2 through a bolt 9 installed in the strip-shaped hole 8, and is convenient to replace. The extension length of the material shoveling plate 5 can be adjusted by adjusting the position of the bolt 9 in the strip-shaped hole 8. The material shoveling plate 5 is made of alloy or rubber and the like, and is solid and durable.

[0030] The lower end of the tapered shaft 1 is further provided with a material scraping plate 6, the material scraping plate 6 can push the feed to the discharge port of the feed mixer truck, and is convenient to discharge the feed quickly. The upper surface of the material scraping plate 6 is provided with a protective plate 7, the protective plate 7 is made of wear-resistant steel plate, and is solid and durable. The protective plate 7 is provided with a strip-shaped hole 8, the protective plate 7 is installed on the material scraping plate 6 through a bolt 9 installed in the strip-shaped hole 8, and is convenient to replace. The extension length of the protective plate 7 relative to the material scraping plate 6 can be adjusted by adjusting the position of the bolt 9 in the strip-shaped hole 8, so that the feed can be discharged better. The protective plate 7 is provided with a bolt protection strip 71 at the position on one side of the strip-shaped hole 8, the bolt protection strip 71 can avoid the bolt 9 from loosening or being damaged due to friction during the feed mixing process.

[0031] The auger of the feed mixer truck in the embodiment adopts the spiral blade 2 which gradually narrows from bottom to top, and is provided with a gap 211 at the lower part of the spiral blade 2, so that sufficient falling space is provided for the feed, the feed can fall back to the bottom and be sent into the spiral blade 2 again for mixing, the feed can be mixed more quickly and uniformly, the mixing efficiency is improved, and the required mixing power is smaller. The inlet of the spiral blade 2 is provided with the replaceable material blocking plate 4 and the material shoveling plate 5, the feed on the edge and the bottom of the mixer truck can be gathered into the auger, and rapid mixing is realized. The material scraping plate 6 provided with the protective plate 7 can discharge the feed quickly, and is solid and durable.
