[0019] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-2 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0020] like Figure 1-2 As shown: Example

[0021] A new type of auger for a mixer comprises a stirring shaft 1, on which fixed rods 2 arranged at vertical intervals are fixed, and also comprises a turning mechanism, which comprises an outer spiral belt arranged at the end of the fixed rod 2, a middle spiral belt 4 fixedly connected to the middle position of the fixed rod 2, and an inner spiral belt 5 arranged at the lower part of the fixed rod 2; a scraping mechanism, which comprises a fixed plate 6 arranged between the fixed rods 2, a U-shaped groove provided in the middle position of the fixed plate 6, a scraper 9 placed in the groove, and the scraper 9 is connected to the fixed plate 6 through an installation assembly.

[0022] In this embodiment, the stirring shaft 1 is installed on the housing of the mixer, and fixed rods 2 are vertically installed on the stirring shaft 1 at intervals. The fixed rods 2 are arranged on both sides of the stirring shaft 1 and fixed on the stirring shaft 1. Multiple layers of spiral ribbons are provided on the fixed rods 2, which are the outer spiral ribbon 3, the middle spiral ribbon 4 and the inner spiral ribbon 5 from the outside to the inside, and the spirals between each layer of spiral ribbons are opposite, so that the material can be fully stirred. A scraping mechanism is provided at the position between the fixed rods 2, and the scraping mechanism can scrape the material stuck to the mixer housing. In addition, since the scraper 9 needs to be replaced after working for a period of time, in order to facilitate replacement, the scraper 9 and the fixed plate 6 are connected by a mounting assembly, and the mounting assembly includes a bolt 8, a movable hole 7 and a mounting hole 10. Example

[0023] The scraper 9 is provided with a mounting hole 10 . The mounting hole 10 is L-shaped and opens at the lower end of the scraper 9 , with the open end located at the edge of the scraper 9 .

[0024] Different from the above embodiment, in this embodiment, the mounting hole 10 is L-shaped and is provided on the scraper 9. Since the scraper 9 and the fixing plate 6 are plug-in connected, there is basically no gap after insertion. During installation, the bolt 8 is moved to the opening position of the mounting hole 10. After the scraper 9 is inserted, the bolt 8 is moved to the middle position and locked. Example

[0025] The scraper 9 is provided with a bolt 8 , and the scraper 9 is also provided with a moving hole 7 . The bolt 8 passes through the moving hole 7 and can move in the moving hole 7 . After being tightened, the bolt 8 is fixed to the scraper 9 .

[0026] Different from the above embodiment, in this embodiment, the bolt 8 on the scraper 9 is used to position the middle position of the scraper 9. Example

[0027] Both ends of the groove on the fixing plate 6 are closed, and the scraper 9 can be inserted into the groove.

[0028] Different from the above embodiment, in this embodiment, the scraper 9 is inserted into a groove on the fixing plate 6 along the axial direction of the stirring shaft 1 . Example

[0029] After the scraper plate 9 is connected to the fixed plate 6 , the positions of the movable hole 7 and the mounting hole 10 correspond to each other.

[0030] Different from the above embodiment, in this embodiment, the positions of the movable hole 7 and the mounting hole 10 correspond to each other, which facilitates the movement of the bolt 8 from one end to the other.

[0031] The working method (or working principle) of this utility model:

[0032] When this technology is working, the auger adopts three layers of spiral belts, and the spiral directions of the spiral belts of each layer are opposite, which can stir the material back and forth during mixing and improve the mixing efficiency. In order to facilitate the replacement of the scraper 9, a moving hole 7, a mounting hole 10 and a bolt 8 are set. When disassembling, loosen the bolt 8, move the bolt 8 to one end, and the scraper 9 can be pulled out. This method does not require the entire bolt 8 to be removed, and reduces the time for aligning the upper nut. After inserting the new scraper 9, move the bolt 8 to the middle position and lock it.

[0033] In the present invention, unless otherwise clearly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly specified and limited, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0034] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
