Technical Field
[0001] This utility model relates to the field of concrete mixing technology, and in particular to a commercial concrete mixing device. Background Technology
[0002] Ready-mixed concrete refers to concrete used for commercial purposes, such as concrete that can be sold or purchased. Most construction projects now use ready-mixed concrete. It is a general term for engineering composite materials in which cementing materials bind aggregates into a whole. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water in a certain proportion, and then mixing, molding and curing it. It is widely used in civil engineering.
[0003] A commercial concrete mixing device disclosed in publication number CN218138912U includes a mixing tank. Three support legs are fixedly installed at the lower end of the mixing tank. A discharge pipe is fixedly connected to one side of the lower end of the mixing tank, and a spiral discharge pipe is connected to the lower end of the discharge pipe. A motor is fixedly installed near the middle of the top of the mixing tank. A water inlet pipe is fixedly connected to one side of the top of the mixing tank near the motor, and another water inlet pipe is fixedly connected to the other side of the top of the mixing tank near the motor. A feed pipe is fixedly connected to the outside of the mixing tank near the top. The output shaft of the motor passes through the interior of the mixing tank, and a connecting rod is fixedly installed at the bottom of the output shaft. This commercial concrete mixing device facilitates scraping the concrete on the inner wall of the mixing tank and prevents dust from being raised and discharged from the feed pipe during concrete mixing.
[0004] However, this type of commercial concrete mixing device has the following disadvantages: during the mixing process, the concrete has strong adsorption properties and is easily adsorbed onto the inner wall of the mixing device, making subsequent cleaning inconvenient and making it difficult for personnel to perform dust suppression operations inside the mixing device. Utility Model Content
[0005] The technical problem solved by the utility model is to provide a commercial concrete mixing device that is highly practical, easy to operate, and has a simple structure. This solves the problem mentioned in the background art that during the concrete mixing process, the concrete has strong adsorption properties and easily adheres to the inner wall of the mixing device, making subsequent cleaning inconvenient and making it difficult for personnel to perform dust suppression operations inside the mixing device.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a commercial concrete mixing device, comprising a mixing drum, a drive motor fixedly connected to the middle of the bottom surface of the mixing drum, a mixing assembly provided at the output end of the drive motor, a top plate snapped onto the top of the mixing drum, a conical cylinder fixedly connected to the top of the top plate, a fixing ring fixedly connected to one side of the inner wall of the conical cylinder, a circular groove provided at the adjacent position of the top surface of the fixing ring, an atomizing nozzle provided inside the circular groove, a cavity provided in the inner wall of the conical cylinder, a water storage tank provided on one side of the mixing drum, and a water spraying assembly provided inside the water storage tank.
[0007] Optionally, the stirring assembly includes a vertical rod fixedly connected to the shaft at the output end of the drive motor, a cross bar fixedly connected to the outer surface of the vertical rod, and a scraping bar fixedly connected to the bottom of the cross bar.

[0009] Optionally, the water spray assembly includes a water pump fixedly connected to the bottom wall of the water storage tank, with an inlet pipe inserted into the inlet end of the water pump and an outlet pipe inserted into the output end of the water pump, one end of which is inserted into one side of the conical cylinder.
[0010] Optionally, a fixing plate is snapped onto one side of the water storage tank, and a transparent plate is embedded on one side of the water storage tank.
[0011] Optionally, a support rod is fixedly connected to the bottom of the stirring tank, and a stabilizing ring is fixedly connected to the bottom of the support rod.
[0012] This utility model provides a commercial concrete mixing device, which has the following beneficial effects:
[0013] 1. This commercial concrete mixing device, through the structural design of the drive assembly, mixing drum, and mixing components, allows personnel to transport concrete into the mixing drum along the conical cylinder when mixing is required. Then, the personnel can connect the drive motor power supply, causing the drive motor to rotate the vertical rod. Subsequently, the cross rod drives the scraping rod to clean the concrete adhering to the inside and inner wall of the mixing drum. This facilitates rapid mixing of concrete and makes subsequent cleaning of the mixing drum's inner wall convenient.
[0014] 2. This commercial concrete mixing device, through the coordinated use of a conical cylinder, atomizing nozzles, and water spraying components, allows personnel to connect the water pump power supply while concrete is being fed into the mixing drum. This enables the water inlet pipe to deliver water to the outlet pipe, and the water is then sprayed into the conical cylinder through the atomizing nozzles. This process effectively reduces dust emitted from the concrete, thus achieving the purpose of dust suppression in the mixing drum. Attached Figure Description

[0022] When personnel use the ready-mixed concrete mixing equipment, they can place the ready-mixed concrete inside the conical cylinder 5. During the concrete transportation process, personnel can turn on the power to the water pump 91, which will transport water from the water storage tank 8 to the inlet pipe 92. Then, the outlet pipe 93 will transport water to the cavity inside the conical cylinder 5. Subsequently, the atomizing nozzle 7 will spray the water into the conical cylinder 5 in an atomized form, creating a water curtain that reduces dust. Then, personnel can turn on the power to the drive motor 2, which will drive the vertical rod 31 to rotate. The cross rod 32 will then mix the concrete inside the mixing drum 1. The scraping rod 33 will then clean the inner wall of the mixing drum 1, making it convenient for personnel to clean foreign objects from the inner wall of the mixing drum 1.
[0023] Please see Figures 1 to 4 A top plate 4 is snapped onto the top of the mixing drum 1. A conical cylinder 5 is fixedly connected to the top of the top plate 4.

One end of the water outlet pipe 93 is inserted into one side of the conical cylinder 5.
[0024] By using the cone 5, atomizing nozzle 7, and water spraying assembly 9 in coordination, when personnel are conveying concrete into the mixing drum 1, they can immediately turn on the power to the water pump 91, so that the water inlet pipe 92 delivers water to the inside of the water outlet pipe 93. Then, the water is sprayed into the inside of the cone 5 through the atomizing nozzle 7, which reduces the dust emitted by the concrete, thereby achieving the effect of dust reduction in the mixing drum 1.
[0025] Please see Figures 1 to 4 A fixing plate 10 is snapped onto one side of the water storage tank 8, and a transparent plate 11 is embedded on one side of the water storage tank 8.

[0027] Please see Figures 1 to 4 A support rod 12 is fixedly connected to the bottom of the mixing drum 1, and a stabilizing ring 13 is fixedly connected to the bottom of the support rod 12.
[0028] By setting up the support rod 12 and the stabilizing ring 13, the stabilizing ring 13 can improve the stability of the mixing drum 1 during the use of the mixing drum 1 by personnel, thereby reducing the vibration of the mixing drum 1.
[0029] In this invention, the working steps of the device are as follows:
[0030] When personnel use the ready-mixed concrete mixing equipment, they can place the ready-mixed concrete inside the conical cylinder 5.

Subsequently, the atomizing nozzle 7 will spray the water into the conical cylinder 5 in an atomized form, creating a water curtain that reduces dust. Then, personnel can turn on the power to the drive motor 2, which will drive the vertical rod 31 to rotate. The cross rod 32 will then mix the concrete inside the mixing drum 1. The scraping rod 33 will then clean the inner wall of the mixing drum 1, making it convenient for personnel to clean foreign objects from the inner wall of the mixing drum 1.
