[0030] See Figures 1 to 5 As shown, this utility model discloses a concrete admixture mixing production device, which includes supports 2 arranged on both sides, and a mixing tank 1 rotatably arranged between the supports 2 on both sides. The mixing tank 1 has a U-shaped cross section and a mixing cavity 1a with one end open. The mixing cavity 1a is provided with a suitable spiral strip 3, which is fixed on the blade shaft 4. The blade shaft 4 is rotatably installed on the mixing tank 1.
[0031] Working principle
[0032] During mixing, first adjust the positioning bolts and insert them into the positioning through holes to prevent the mixing drum from rotating. Then, add the raw materials to be mixed sequentially or simultaneously as needed. Then, rotate the drum forward or in reverse or alternately to fully mix the raw materials.
[0033] When discharging, adjust the positioning bolts and pull them out of the positioning through holes. Then, rotate the mixing drum from the direction of discharge to the specific position. Adjust the positioning bolts again and insert them into the positioning blind holes to completely pour out the mixed raw materials.
[0034] To clean, simply rotate the mixing tank in the opposite direction.
[0035] In some embodiments, see Figure 4 and 5 As shown, a positioning bolt 9 is provided on one side of the bracket 2;
[0036] The mixing tank 1 is provided with at least one positioning through hole 1c and at least one positioning blind hole 1d;
[0037] The positioning through hole 1c and the positioning blind hole 1d are adapted to the positioning bolt 9.
[0038] Positioning bolts are used to position the mixing tank;
[0039] The positioning through-hole is used to restrict the rotation of the mixing drum during mixing;
[0040] Positioning blind holes are used to restrict the rotation of the mixing tank during material discharge or cleaning.
[0041] In some embodiments, see Figure 4 and 5 As shown, the bracket 2 is provided with a nut seat 2a, and the positioning bolt 9 is adjustablely installed in the nut seat 2a;
[0042] The positioning through hole 1c and the nut seat 2a are both located directly above the blade shaft 4.
[0043] In some embodiments, see Figure 5 As shown, the angular distance between the positioning blind hole 1d and the positioning through hole 1c is greater than 90° or greater than -90°, and the positioning blind hole 1d and the positioning through hole 1c are on the same circumference.
[0044] In this way, the mixing tank opening faces downwards after rotation, making it easier to pour out the mixed materials and also easier to clean.
[0045] In some embodiments, see Figure 2 and 3 As shown, the blade shaft 4 is rotatably mounted on the inner bearing seat 5 via a bearing, and the inner bearing seat 5 is mounted on the mixing tank 1.
[0046] In some embodiments, see Figure 4 and 5 As shown, the mixing tank 1 is rotatably mounted on the outer bearing seat 6 via the tank shaft 1b and bearings on both sides, and the outer bearing seat 6 is mounted on the bracket 2.
[0047] In some embodiments, see Figure 4 and 5 As shown, the blade shaft 4 penetrates the barrel shaft 1b on any side, and a mixing handle 7 is installed on the through side of the blade shaft 4.
[0048] In some embodiments, see Figure 1 As shown, the bottom of the mixing tank 1 is provided with a discharge handle 8.
[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
