[0043] The lower surface of the top plate 3 does not contact the upper surface of the bottom plate 1. An inlet hole 4 is vertically opened at the middle position of the top plate 3. A mixing barrel 5 is fixedly connected to the lower surface of the top plate 3. It is assumed that the shape of the mixing barrel 5 is a circular barrel, and the upper end of the mixing barrel 5 is an open mouth. In this embodiment, the diameter of the open mouth is equal to the aperture of the inlet hole 4, and the axis of the open mouth coincides with the axis of the inlet hole 4.
[0044] The lower surface of the mixing barrel 5 is fixedly connected to the upper surface of the bottom plate 1 through a bracket.

[0045] A mixing component is further provided on the support plate 8, and a controller 7 for controlling the mixing component is provided on the top plate 3. Refer to Figure 1 and Figure 2 , the mixing component includes:
[0046] A mounting frame 9, fixed on the support plate 8. In this embodiment, when viewed in the horizontal X direction in Figure 1 , the mounting frame 9 is in an inverted "U" shape.
[0047] A lifting motor 10, the non-rotating shaft end of which is fixed on the mounting frame 9. In this embodiment, it is assumed that the axis of the rotating shaft of the lifting motor 10 is along the Y direction, the Y direction is along the horizontal direction, and the Y direction is perpendicular to the X direction.
[0048] A driving disk 11, fixed on the rotating shaft of the lifting motor 10. In this embodiment, the driving disk 11 is a circular disk, and the axis of the driving disk 11 coincides with the axis of the rotating shaft of the lifting motor 10.
[0049] An eccentric shaft 12, fixed on the surface of the driving disk 11 away from the lifting motor 10. The axis of the eccentric shaft 12 is along the Y direction, and the axis of the eccentric shaft 12 does not coincide with the axis of the driving disk 11.

[0056] The process of using this equipment
[0057] Pour the materials needed for concrete mixing into the feed holes 4: cement, lime, water, etc.
[0058] Simultaneously, the mixing motor 17 and the lifting motor 10 are activated. The lifting motor 10 causes the drive disc 11 and the eccentric shaft 12 to rotate as a whole. Since the eccentric shaft 12 passes through the slotted hole, it drives the linkage plate 13, the first limiting rod 14, the second limiting rod 15, the equipment plate 16, the mixing motor 17, and the mixing rod 18 to rise and fall as a whole. At the same time, the mixing motor 17 also drives the mixing rod 18 to rotate, so that the material is mixed vertically while being mixed by the rotation of the mixing rod 18, thus achieving mixing in two dimensions. After mixing is completed, the valve on the discharge pipe 6 is opened to allow the concrete to flow out of the mixing tank 5.
[0059] Example 2: A concrete mixing device for civil engineering. Since the mixing rod 18 is inserted through the feed hole 4 in Example 1, the operator will be interfered with by the mixing rod 18 when pouring concrete into the feed hole 4. Therefore, this example is used to solve the problem of interference by the mixing rod 18 when pouring materials.
[0060] The difference between this embodiment and Embodiment 1 lies in the support plate 8. In this embodiment, a limiting component is used instead of the support plate 8. The limiting component includes:
[0061] The fixing sleeve 21 is fixed to the upper surface of the top plate 3; the fixing sleeve 21 has a sliding groove along the vertical direction.
[0062] The sliding plate 22 and the fixed sleeve 21 are movably mounted on the sliding plate 22 by means of the sliding groove. The sliding plate 22 can slide vertically relative to the fixed sleeve 21, and the upper end of the sliding plate 22 passes through the sliding groove.
[0063] The limiting bolt 23 is threaded onto the fixing sleeve 21. In this embodiment, the axis of the limiting bolt 23 is along the Y direction, and the end of the limiting bolt 23 abuts against the surface of the slide plate 22. Through the friction of the limiting bolt 23, the slide plate 22 and the above-ground structure are ensured to not move arbitrarily vertically relative to the fixing sleeve 21 as a whole. In other solutions, multiple limiting bolts 23 can be set to prevent the slide plate 22 and the above-ground structure from moving arbitrarily.
[0064] The connecting plate 24 is rotatably connected to the slide plate 22 at its lower end via a pivot. Viewed in the X direction, the connecting plate 24 is inverted L-shaped. The pivot of the connecting plate 24 is along the Y direction. The mounting bracket 9 and the parts connected to the mounting bracket 9 in the aforementioned embodiment 1 are correspondingly mounted on the connecting plate 24.
[0065] A sleeve 25 is fixed to the circumferential side wall of the fixing sleeve 21. A vertical through hole is provided along the upper edge of the sleeve 25. In this embodiment, the upper surface of the sleeve 25 is flush with the upper surface of the fixing sleeve 21. When the lower surface of the connecting plate 24 abuts against the upper surface of the sleeve 25, the stirrer 18 is positioned precisely in the corresponding position within the mixing tank 5, ensuring that the mixing tank 5 can meet the requirements for stirring the materials within it.
[0066] The L-shaped folding rod 26 is fixed to the vertical part of the connecting plate 24, and the vertical part of the folding rod 26 can be inserted into the through hole. The lower end of the folding rod 26 is adapted to the shape of the through hole.
[0067] The difference between the usage process of Example 2 and Example 1 is that before pouring the materials required for concrete mixing into the feed hole 4, the limiting bolt 23 needs to be loosened first. Then, the slide plate 22 and all parts connected to the slide plate 22 are moved upward until the bending rod 26 disengages from the through hole of the sleeve plate 25. At this time, the mixing rod 18 also disengages from the mixing drum 5. At this time, the sleeve plate 25, the bending rod 26, and all parts connected to the sleeve plate 25 can rotate relative to the slide plate 22, so that the axis of the mixer no longer coincides with the axis of the feed hole 4, until the mounting bracket 9 abuts against the side of the top plate 3 after rotating around the axis of the connecting plate 24. At this time, the mixer avoids the feed hole 4, and the mixer no longer interferes with the feed hole 4, making it convenient for the material to enter the mixing drum 5 from the feed hole 4.
[0068] After pouring in the material, rotate all parts connected to the slide plate 22 until the folding rod 26 is aligned with the through hole of the sleeve plate 25. Then move the slide plate 22 and all parts connected to the slide plate 22 vertically until the lower end of the folding rod 26 is inserted into the through hole. Ensure that the folding rod and all parts connected to the slide plate 22 cannot rotate freely around the axis of the connecting plate 24. At the same time, during the descent of the connecting plate 24, it contacts the upper surface of the sleeve plate 25, indicating that the agitator 18 has reached the position corresponding to the mixing tank 5. At this time, tighten the limiting bolts again.
[0069] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
