[0002] Concrete is one of the most important civil engineering materials in modern times. It is a kind of artificial stone prepared by mixing cementitious materials, granular aggregates (also known as aggregates), water, and additives and admixtures added when necessary in a certain proportion, and through uniform stirring, dense forming, and curing and hardening. Concrete has the characteristics of rich raw materials, low price, and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make its application range very wide, and it is not only used in various civil engineering projects, but also an important material in the shipbuilding industry, mechanical industry, ocean development, geothermal engineering, etc.

[0003] For example, in the patent named: A Concrete Mixer Facilitating Cleaning (patent application number: CN202322576603.3), a concrete mixer facilitating cleaning is disclosed. The bottom of the mixing barrel is horizontally divided into multiple rotating covers from bottom to top. One side of the rotating cover is horizontally rotatably connected to one side above the bottom of the mixing barrel, and the other side is fixed by a fixing rod. When it is necessary to clean the mixing barrel, after the stirring mechanism is lifted by the lifting frame until it is completely separated from the mixing barrel, the fixing rod is removed, and the multiple rotating covers above the bottom of the mixing barrel can rotate horizontally freely. The staff can rotate and stagger each rotating cover for cleaning, which is more convenient and simple, and ensures the cleaning effect. However, the stirring blades will rise to a certain height synchronously, which is more troublesome to clean, and additional tools are needed to clean the inner wall of the mixing barrel, and the use efficiency needs to be improved.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] The present utility model provides a dispersion stirring device for concrete preparation as Figures 1 to 6 shown, including a frame 1, and a discharge hopper 2 is fixedly connected to the frame 1. During specific use, a control valve (not shown in the figure) is provided on the discharge hopper 2. Considering that existing concrete mixers are usually of an integrated design and the mixing drum is usually relatively deep, to improve the cleaning efficiency, a mixing drum 3 is rotatably provided above the discharge hopper 2. The discharge hopper 2 is communicated with the mixing drum 3 to form a mixing barrel body. A plurality of mixing drums 3 are provided, and the mixing drums 3 can rotate. When stirring operation is required, the mixing drum 3 and the discharge hopper 2 are coaxially communicated up and down; when cleaning is required, the mixing drum 3 is rotated to stagger it from the discharge hopper 2, and at the same time, a plurality of mixing drums 3 are staggered from each other. Since the height of a single mixing drum 3 is small, it is convenient for cleaning.

[0024] A circular ring 7 is fixedly connected to the inner wall of the mixing drum 3, and a sliding frame 8 is slidably provided on the circular ring 7. Two sliding frames 8 are provided, and the two sliding frames 8 are symmetrically distributed about the axis of the mixing drum 3. A mixing blade 9 is fixedly connected between the two sliding frames 8. The sliding frame 8 slides on the circular ring 7 to drive the mixing blade 9 to rotate, and the mixing blade 9 dispersedly stirs the material; since the mixing blade 9 is arranged inside the mixing drum 3, it is convenient for cleaning.

[0025] A scraping plate 10 is fixedly connected to the carriage 8, and the scraping plate 10 is slidably attached to the inner wall of the mixing drum 3. When the carriage 8 slides on the ring 7, the scraping plate 10 scrapes and cleans the inner wall of the mixing drum 3 to prevent materials from adhering to the inner wall of the mixing drum 3.

[0026] And during the cleaning process, the scraping plate 10 can scrape and clean the inner wall of the mixing drum 3 without the need to use additional tools.

[0027] By setting the mixing drum body to be composed of a discharge hopper 2 and a mixing drum 3 spliced together, and the mixing blades 9 are arranged inside the mixing drum 3, it is convenient for cleaning. At the same time, the scraping plate 10 scrapes and cleans the inner wall of the mixing drum 3 to prevent materials from adhering to the inner wall of the mixing drum 3, without the need to use additional tools, improving the usage efficiency.

[0028] Ring sleeves 4 are fixedly connected to both sides of the outer wall of the discharge hopper 2, and round sleeves 5 are fixedly connected to both sides of the outer wall of the mixing drum 3. A vertical shaft 6 is inserted through between the round sleeve 5 and the corresponding ring sleeve 4. The mixing drum 3 rotates around one of the vertical shafts 6. When the mixing operation needs to be carried out, the mixing drum 3 and the discharge hopper 2 are coaxially connected up and down to form a mixing drum body, and the other vertical shaft 6 is inserted into the corresponding round sleeve 5 and ring sleeve 4 to fix the position of the mixing drum 3, thus facilitating the dispersion mixing operation.

[0029] Cylinders 11 are fixedly connected to both sides of the frame 1, and a cross plate 12 is fixedly connected between the telescopic ends of the two cylinders 11. One of the vertical shafts 6 is fixedly connected to the cross plate 12. When the telescopic end of the cylinder 11 is controlled to extend, the vertical shaft 6 fixedly connected to its bottom is driven by the cross plate 12 to move upward and be pulled out from the corresponding round sleeve 5 and ring sleeve 4, so that the mixing drum 3 can rotate around the other vertical shaft 6, and multiple mixing drums 3 are staggered from each other, thus facilitating cleaning; when stirring is required after the cleaning is completed, the mixing drum 3 and the discharge hopper 2 are adjusted to be coaxially connected up and down, and the telescopic end of the cylinder 11 is controlled to retract, and the vertical shaft 6 fixedly connected to its bottom is driven by the cross plate 12 to move downward, and the vertical shaft 6 is inserted into the corresponding round sleeve 5 and ring sleeve 4.

[0030] To drive the mixing blades 9 to rotate, a spline sleeve 15 is inserted through the mixing blades 9. The spline sleeve 15 is fixedly connected to the mixing blades 9, and the spline sleeve 15 is coaxially arranged with the mixing drum 3. A driving component matched with the spline sleeve 15 is arranged on the cross plate 12. The driving component includes a motor 13 and a spline shaft 14. The motor 13 is fixedly connected to the cross plate 12. A circular groove for the driving shaft of the motor 13 to pass through is opened on the cross plate 12. The spline shaft 14 is fixedly connected to the driving shaft of the motor 13, and the spline shaft 14 is matched with the spline sleeve 15.

[0031] When stirring is required after the cleaning is completed, adjust the mixing drum 3 and the discharge hopper 2 to be coaxially connected up and down. Control the retraction of the telescopic end of the cylinder 11. Drive the spline shaft 14 fixedly connected to the bottom thereof to move downward through the cross plate 12. The spline shaft 14 is inserted into the inside of the spline sleeve 15. The motor 13 rotates to drive the spline shaft 14 to rotate, and the spline shaft 14 rotates to drive the spline sleeve 15 to rotate. The stirring blades 9 disperse and stir the materials. When the telescopic end of the cylinder 11 extends, drive the spline shaft 14 fixedly connected to the bottom thereof to move upward through the cross plate 12, and pull it out of the spline sleeve 15, without affecting the rotation of the mixing drum 3.
