Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Example 1

The utility model provides a novel stirrer blade, as shown in figure 1 and figure 2, including first blade 2 and second blade 3, on the main shaft 1 of the fixed mixer of first blade 2, first blade is followed mixer main shaft helix distributes, adjacent first blade on the helix at interval 90 degrees, and first blade with the contained angle of mixer main shaft axis is less than 90 degrees, and 2 outer ends of first blade are equipped with first recess, and second blade 3 is fixed on the first recess, 3 outer sword salient of second blade are in the outer sword of first blade 2. The first blades 2 rotate along with the main shaft 1, the first blades 2 arranged in a staggered mode play a role in stirring materials, the second blades 3 rotate along with the first blades 2, the second blades 3 cut the bonding materials on the inner wall of the stirrer, and the bonding materials enter the stirring range of the first blades 2 after being separated from the inner wall, so that the functions of preventing bonding and cleaning the bonding materials are achieved.

The second blades 3 may be made of tungsten steel, and in one embodiment, the second blades 3 have a size of 10mm by 20mm, the first grooves have a size of 10mm by 10mm, and three second blades 3 are used, and the three second blades 3 are uniformly distributed along the outer edge of the first blade 2. Second blade 3 can reduce gradually along the direction height of main shaft 1 rotation, makes second blade 3 be the arc, is convenient for cut bonding thing, and the cutting edge of second blade 3 can be sharper than the cutting edge of first blade 2, and bonding thing hardness is higher than the hardness of stirring thing, and the cutting edge of sharper is convenient for second blade 3 and cuts bonding thing, and second blade 3 plays the stirring effect, and second blade 3 can pass through welded fastening on first blade 2.

The first blade 2 is fan-shaped or spiral, and the spiral blade is beneficial to improving the stirring effect. The arc length of the outer end of the first blade 2 is 15-30 mm, and a blade with the diameter of 15mm, 24mm or 30mm is adopted in the specific implementation. The minimum distance between the outer end of the second blade 3 and the shell of the stirrer is 3-10 mm, and the shell is easily scratched when the distance is too small; the spacing is too large, which reduces the efficiency of cutting the adhesive, and in particular embodiments, the spacing is controlled to be 3mm or 10 mm. The height of the first blade 2 can be reduced along the rotation direction of the main shaft, namely the height of the front end of the first blade 2 is reduced, which is beneficial to reducing resistance; simultaneously first blade 2 advances the end and can also be equipped with the cutting edge to the cutting stirring thing, in order to do benefit to the reduction resistance, improve stirring effect.

The novel blade of the stirrer can be applied to a single-shaft stirrer or a double-shaft stirrer, and when the novel blade of the stirrer is applied specifically, the first blades 2 are uniformly distributed on the main shaft 1 in a staggered manner; the novel blade of the stirring machine can greatly reduce the bonding phenomenon of the inner wall of the stirring machine, reduce the manual cleaning steps and effectively reduce the working current of the motor of the stirring machine.

Example 2

Different from the embodiment 1, as shown in fig. 2, the bottom end of the second blade 3 is provided with a second groove, and when the second blade 3 is installed in the first groove, the second groove is nested at two sides of the first blade 2, so that the stress surface at the bottom of the second blade 3 is enlarged, and the second blade 3 is firmer and is not easy to fall off. Meanwhile, a through hole penetrating through the first blade 2 and the second blade 3 is formed in one side face of the second blade 3, and the second blade 3 is fixed on the first blade 2 through a bolt and a nut.

The bottom end of the first blade 2 can be fixed on a hoop, and the first blade 2 is detachably fixed on the main shaft 1 of the stirring machine through the hoop.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
