[0003] The existing mixer uses a leaf-shaped stirring tool, which is similar in shape to a leaf, and forms a stirring effect through the mixer's driving device. However, this structure has the problem that cement particles are easily agglomerated at the bottom of the container during the stirring process, which will affect the actual test results. Moreover, this stirring tool rotates radially and cannot achieve up and down interaction, which will also affect the actual test results. Utility Model Content

[0012] The lower stirring blade is provided with a first blade and a second blade, the first blade extends obliquely upward, and the second blade extends obliquely downward.

[0013] By extending the first blade and the second blade in different directions, a small-range stirring effect is formed, so that the cement particles at the lower end are better stirred and the stirring rate is accelerated.

[0014] The upper stirring blade is provided with a third blade, and the third blade extends toward one side of the lower stirring blade.

[0015] The third blade forms a cooperative effect with the first blade, and cooperates up and down to form a stirring effect, thereby improving the stirring efficiency and forming an upward and downward interactive effect.

[0016] Among them, the first blade, the second blade and the third blade are all blunt blade structures.

[0017] The blunt knife setting is used to break up the cement particles that are clumped together, so that the cement particles and water can be better matched.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Example 1

[0033] This embodiment provides a mixing tool for a cement slurry mixer, as shown in the attached Figure 1-3 As shown, including:

[0034] The stirring shaft 11 , the upper end of the stirring shaft 11 is used to cooperate with the stirring machine, specifically cooperate with the driving mechanism in the stirring machine, to achieve the radial rotation effect of the stirring shaft 11 .

[0035] The upper stirring blade 12 is sleeved on the upper end of the stirring shaft 11 . The upper stirring blade 12 and the stirring shaft 11 form a linkage effect. The upper stirring blade 12 can rotate with the stirring shaft 11 .

[0036] The lower stirring blade 13 is sleeved on the lower end of the stirring shaft 11 . The lower stirring blade 13 and the stirring shaft 11 also form a linkage effect. The lower stirring blade 13 can rotate with the stirring shaft 11 .

[0037] The spiral blade 14, a bolt blade sleeve, is arranged on the stirring shaft 11. The spiral blade 14 is spirally shaped as its name implies. The spiral blade 14 is located between the upper stirring blade 12 and the lower stirring blade 13. Here, the spiral blade 14 can be against the upper stirring blade 12 and the lower stirring blade 13, or the spiral blade 14 can be located between the two, and the spiral blade 14 can slide up and down relative to the stirring shaft 11.

[0038] This structural setting creates a stirring effect both up and down, and the spiral blades 14 interact up and down to form a vortex effect, so that the cement particles interact better, the stirring is more sufficient, and the cement particles are less likely to agglomerate. At the same time, each component is independently set and can be disassembled and cleaned during the cleaning process.

[0039] Specifically, as attached Figure 1-3 As shown, the lower stirring blade 13 is provided with a first blade 131 and a second blade 132. The number of the first blades 131 is two, and the two first blades 131 are symmetrically arranged, and the first blades 131 extend horizontally outward. The number of the second blades 132 is also two, and the two second blades 132 are also symmetrically arranged, and the second blades 132 extend obliquely downward, where the downward direction is away from the upper stirring blade 12. By extending the first blade 131 and the second blade 132 in different directions, a small-range stirring effect is formed, so that the cement particles at the lower end can be better stirred and the stirring rate can be accelerated. In addition, the blades of the lower stirring blade 13 can also extend horizontally outward, and the stirring effect can also be achieved. The pressure difference generated by the blades can also adsorb the cement particles at the lower end of the container.

[0040] Specifically, as attached Figure 1-3 As shown, the lower stirring blade 13 is provided with a first blade 131 and a second blade 132, the first blade 131 extends obliquely upward, and the second blade 132 extends obliquely downward. By extending the first blade 131 and the second blade 132 in different directions, a small-scale stirring effect is formed, so that the cement particles at the lower end are better stirred and the stirring rate is accelerated. The difference between the technical solution here and the above technical solution is that the first blade 131 extends obliquely upward and can be set corresponding to the third blade located above to improve the effect of rotary stirring.

[0041] Specifically, as attached Figure 1-2 As shown, the upper stirring blade 12 is provided with a third blade 121, and the number of the third blades 121 can be two, three, or four, and each third blade 121 is distributed in a circumferential array. The third blade 121 extends toward one side of the lower stirring blade 13. The third blade 121 forms a cooperation effect with the first blade 131, and the upper and lower cooperation forms a stirring effect, improves the stirring efficiency, and forms an upper and lower interactive effect.

[0042] Specifically, the first blade 131, the second blade 132, and the third blade 121 are all blunt blade structures. The blunt blade structure specifically means that the outer surface of the blade is not a sharp surface, but also has a certain thickness. The blunt blade setting is used to break up the aggregated cement particles, so that the cement particles and water can be better matched.

[0043] Specifically, as attached Figure 1-2 As shown, the first blade 131, the second blade 132, and the third blade 121 are all provided with through holes. The provision of the through holes creates a circulation effect and reduces resistance. The number and size of the through holes here can be adjusted according to actual needs.

[0044] Specifically, as attached Figure 1-2 As shown, the stirring shaft 11 is provided with a stepped groove 111, and the upper stirring blade 12 is against the stepped groove 111 to form a fixed offset effect. The stepped groove 111 of the stirring shaft 11 is located near the top surface, and the cross-sectional size of the stirring shaft 11 near the top surface is larger than the cross-sectional size of the rest of the stirring shaft 11, so a stepped structure is formed. The installation process is to first sleeve the upper stirring blade 12 on the stirring shaft 11, then sleeve the spiral blade 14, and finally sleeve the lower stirring blade 13. The lower stirring blade 13 and the stirring shaft 11 can be fixed by nuts, can be fixed by snap-on connection, or can be fixed by welding. It is preferably fixed with nuts here, so that each component can be disassembled, which is convenient for cleaning and improves convenience. If one of the components is damaged, it can also be replaced.

[0045] Specifically, as attached Figure 2As shown, the first buffer 15 and the second buffer 16 are also included. The first buffer 15 and the second buffer 16 are both sleeved on the stirring shaft 11. The first buffer 15 is located between the upper stirring blade 12 and the spiral blade 14, and the second buffer 16 is located between the lower stirring blade 13 and the spiral blade 14. The arrangement of the buffer enables the spiral blade 14 to form an axial up-and-down movement effect, better realize the vortex effect, improve the stirring efficiency, and better realize the up-and-down interaction effect.

[0046] Specifically, as attached Figure 1-2 As shown, the spiral blade 14 includes a first fixing portion 141 and a second fixing portion 142, the first fixing portion 141 abuts against the first buffer 15, and the second fixing portion 142 abuts against the second buffer 16. The arrangement of the first fixing portion 141 and the second fixing portion 142 enables the spiral blade 14 to achieve a better fixing effect, and makes the force given by the buffer to the bolt blade more stable.

[0047] Specifically, the first buffer member 15 and the second buffer member 16 are straight springs or conical springs or elastic structures.

[0048] Specifically, the overall assembly steps are: firstly, the upper stirring blade 12 is abutted against the stepped groove 111, and then the first buffer member 15, the spiral blade 14, the second buffer member 16, and the lower stirring blade 13 are installed, and finally a fixing effect is formed.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
