Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a high-uniformity concrete stirring device. Background Art

[0002] Concrete, abbreviated as concrete, is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; mixed with water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering. In the concrete production process, a concrete mixing device is needed to mix the raw materials so that the required concrete products can be obtained.

[0003] The patent specification with announcement number CN213440398U discloses a concrete mixing device with uniform mixing. The rotating shaft can be controlled to rotate in opposite directions to the mixing barrel through gear No. 1, gear No. 2 and the first conveyor belt, so that the main stirring blade and the stirring barrel have opposite stirring directions, which can make the concrete raw materials mixed more evenly, and under the action of gear No. 3, gear No. 4 and the transmission assembly, the secondary stirring blade will rotate during the stirring process of the main stirring blade, thereby further improving the uniformity of the mixing of the concrete raw materials and thus improving the quality of the concrete product.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: when the above device is used to stir concrete, concrete is easily accumulated at the bottom of the stirring device, and the accumulated concrete at the bottom is not easy to swing again, that is, the accumulated concrete is not easy to be stirred again by the stirring device, which makes the concrete unevenly stirred. Therefore, further improvement is needed. Utility Model Content

[0005] The utility model provides a high-uniformity concrete mixing device, which solves the problem in the related art that it is inconvenient to mix concrete with high uniformity.

[0006] The technical solution of the utility model is as follows:

[0007] A high uniformity concrete mixing device comprises a mixing tank, wherein a bottom cover is arranged at the lower end of the mixing tank, a cross-shaped connecting rod is fixedly connected to the inner wall of the mixing tank, a round block is fixedly connected to one end of the cross-shaped connecting rod, and a mixing assembly is arranged inside the mixing tank.

[0008] Preferably, a first annular groove is provided at one end of the mixing tank, a rotating groove is provided at the upper end of the bottom cover, a second annular groove is provided on the inner wall of the rotating groove, and a limiting groove is provided at one end of the round block.

[0009] Preferably, the stirring assembly comprises a rotating shaft movably arranged inside the stirring tank, stirring blocks are evenly fixedly connected to the outer surface of the rotating shaft, and a follower block is fixedly connected to the lower end of the rotating shaft.

[0010] Preferably, one end of the follower block is fixedly connected to a round rod, the round rod is rotatably connected to the inside of the rotating groove, and one end of the round rod is fixedly connected to an extension block.

[0011] Preferably, the extension block is rotatably connected to the inside of the second annular groove, a cross-shaped connection block is fixedly connected to the outer surface of the follower block, and one end of the cross-shaped connection block is fixedly connected to the first annular block.

[0012] Preferably, a second ring block is fixedly connected to the outer surface of the first ring block, the second ring block is rotatably connected to the first ring groove, and a cross-shaped connecting shaft is fixedly connected to the outer surface of the rotating shaft.

[0013] Preferably, one end of the cross-shaped connecting shaft is fixedly connected with a third ring block, and the outer surface of the third ring block is evenly fixedly connected with cleaning blocks.

[0014] Preferably, the cleaning block is attached to the inner wall of the mixing tank, the upper end of the rotating shaft is fixedly connected with a driving shaft, the driving shaft is rotatably connected to the inside of the limiting groove, and the driving shaft is externally connected to a motor.

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. The utility model drives the driving shaft to rotate inside the first ring groove through a motor. At this time, the driving shaft will synchronously drive the rotating shaft and the follower block to rotate. The stirring block can stir and mix the concrete inside the mixing tank. The second ring block will rotate inside the first ring groove. As the cross-shaped connecting block and the first ring block rotate, the cross-shaped connecting block and the first ring block will lift the concrete at the bottom of the mixing tank, that is, lift the concrete on the upper end of the bottom cover. Because the concrete at the bottom of the mixing tank is the most turbid, as the concrete at the bottom of the mixing tank is lifted, the stirring block stirs the lifted concrete again, thereby enhancing the degree of concrete mixing, thereby improving the uniformity of the concrete, and solving the problem of inconvenience in mixing the concrete with high uniformity.

[0017] 2. The utility model can limit the extension block by the presence of the second ring groove, so as to prevent the round rod from escaping from the inside of the rotating groove. The presence of the limiting groove can prevent the position of the rotating shaft from shifting. When the inner wall of the mixing tank needs to be cleaned, the staff separates the mixing tank from the bottom cover. Due to the presence of the extension block, the staff will simultaneously drive the rotating shaft to move when pulling the bottom cover. At this time, the rotating shaft drives the third ring block to move. Since the cleaning block is attached to the inner wall of the mixing tank, as the third ring block drives the cleaning block to move along the inner wall of the mixing tank, the concrete attached to the inner wall of the mixing tank is cleaned.
