Description

Technical Field

[0001] This utility model relates to the technical field of concrete, and in particular to a self-compacting concrete mixing device. Background Technology

[0002] Self-compacting concrete refers to concrete that can flow and compact under its own weight, completely filling the formwork even with dense reinforcing steel, while achieving good homogeneity, and without requiring additional vibration.

[0003] Existing self-compacting concrete mixing devices, such as the self-compacting concrete batching machine disclosed in utility model patent application number 202021833806.6, mainly include a fixing device, a raw material device, a weighing device, and a mixing device. A conveying pipe and a connecting rod are fixedly connected to the left inner wall of the fixing device, with the connecting rod located below the conveying pipe. The raw material device is set on the left inner wall of the fixing device. In use, through the conveying pipe, three different batching input ports—a gravel raw material box, a dry mortar raw material box, and a water tank—are ultimately introduced into a weighing device for weighing. The rotation of the mixing fan disperses the lumps of dry mortar, while simultaneously ensuring that the various powders in the dry mortar are fully mixed. After being screened by a filter screen, the mixture enters the conveying pipe.

[0004] However, most existing mixing devices are designed for one-time feeding, with aggregates and powders stratified within the device, increasing the difficulty of mixing, prolonging the subsequent mixing time, and making it difficult to mix concrete at the discharge port, which can easily cause blockage and affect the discharge. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a self-compacting concrete mixing device that can not only screen aggregates and powders separately and feed them into the device in batches to facilitate subsequent mixing and improve work efficiency, but also mix and transport concrete at the bottom discharge port to avoid clogging at the discharge port.

[0006] This utility model discloses a self-compacting concrete mixing device, including a mixing mechanism; it also includes two sets of feeding mechanisms, two sets of batching mechanisms, a mixing mechanism, a discharging mechanism, and a water supply mechanism. The two sets of feeding mechanisms are installed on the mixing mechanism to facilitate material screening. The two sets of batching mechanisms are respectively installed on the two sets of feeding mechanisms to feed materials in batches. The mixing mechanism is installed on the mixing mechanism to mix the materials. The discharging mechanism is installed on the mixing mechanism to facilitate material discharge. The water supply mechanism is installed on the feeding mechanism to facilitate water supply. The water supply mechanism first delivers a certain amount of water into the mixing mechanism. Then, the aggregates and powders are respectively conveyed to two sets of feeding mechanisms, which screen them. The batching mechanism feeds the materials into the mixing mechanism in batches. The stirring mechanism is started to stir the materials while dispersing them, enhancing the mixing effect. After the materials in the feeding mechanism are completely discharged, the water supply mechanism sprays water into the two sets of feeding mechanisms to rinse them and deliver clean water to the mixing mechanism to facilitate the formation of concrete. The discharge mechanism stirs the materials at the discharge port to enhance the overall fluidity of the concrete, making it easier to discharge through the mixing mechanism after the concrete is mixed.

[0007] Preferably, the mixing mechanism includes a mixing chamber, a discharge hopper, a discharge pipe, and a valve. The bottom of the mixing chamber is connected to the ground, and the interior of the mixing chamber is provided with a cavity. The top of the discharge hopper is connected to the interior of the bottom of the mixing chamber, and the top of the discharge pipe is connected to the interior of the bottom of the discharge hopper. The valve is installed on the discharge pipe. The concrete is mixed and stirred in the cavity of the mixing chamber. After the mixing is completed, the valve is opened, and the concrete is discharged through the discharge pipe. The discharge hopper is set to accelerate the discharge of concrete.

[0008] Preferably, the feeding mechanism includes a feeding hopper, a hinge, a sealing cover, a handle, and a screen. The bottom of the feeding hopper is connected to the top of the mixing hopper. The top of the feeding hopper has a feed inlet. The hinge is installed on the feeding hopper, the sealing cover is installed on the hinge, the handle is installed on the sealing cover, and the screen is installed inside the feeding hopper. The operator operates the handle to open the sealing cover, feeding the aggregate and powder into the two sets of feeding hoppers respectively. Then, the sealing cover is closed to prevent the powder from scattering. The screen separates the aggregate and powder to ensure the mixing effect of the concrete.

[0009] Preferably, the batching mechanism includes a stepper motor, a first rotating shaft, and four sets of partition plates. The stepper motor is installed on the mixing chamber, the first rotating shaft is rotatably installed in the feeding chamber and is connected to the stepper motor for transmission, and the four sets of partition plates are all installed on the first rotating shaft. When the stepper motor is started, the stepper motor drives the first rotating shaft to rotate 90° each time, so that the partition plates feed the material into the cavity of the mixing chamber in batches, avoiding the accumulation of the same type of material and affecting the mixing effect.

[0010] Preferably, the mixing mechanism includes a first motor, a first reducer, a second rotating shaft, multiple sets of mixing rods, a dispersing disc, and multiple sets of dispersing baffles. The bottom end of the first motor is connected to the top end of the mixing chamber, the output end of the first motor is connected to the input end of the first reducer, and the output end of the first reducer is connected to the input end of the second rotating shaft. Multiple sets of mixing rods are all mounted on the second rotating shaft, the dispersing disc is mounted on the second rotating shaft, and multiple sets of dispersing baffles are mounted on the dispersing disc. When the first motor is started, it drives the second rotating shaft to rotate via the first reducer. The second rotating shaft drives the dispersing disc to rotate, causing the powder and aggregate to fall onto the dispersing disc. The rotating dispersing disc throws them out, thus evenly dispersing the aggregate and powder. At the same time, the second rotating shaft drives the multiple sets of mixing rods to rotate and mix the powder and aggregate to form concrete.

[0011] Preferably, the dispersion disc is made of high-chromium cast iron; high-chromium cast iron has high hardness and excellent wear resistance, and the chromium carbides can effectively resist the cutting and wear of aggregates, avoiding damage to the dispersion disc caused by frequent impacts of aggregates.

[0012] Preferably, the discharge mechanism includes a second motor, a second reducer, a third rotating shaft, and multiple sets of push plates. The second motor is installed on the mixing chamber, and the output end of the second motor is connected to the input end of the second reducer. The output end of the second reducer is connected to the input end of the third rotating shaft, and the multiple sets of push plates are all installed on the third rotating shaft. When the first motor is started, it drives the second rotating shaft to rotate through the first reducer. The second rotating shaft drives the dispersing disc to rotate, and the powder and aggregate fall onto the dispersing disc. The rotating dispersing disc throws them out, so that the aggregate and powder are evenly dispersed. At the same time, the second rotating shaft drives multiple sets of stirring rods to rotate and mix the powder and aggregate to form concrete.

[0013] Preferably, the water supply mechanism includes a water pump, a water delivery hose, two sets of water distributors, two sets of control valves, and multiple sets of nozzles. The water pump is installed on the discharge hopper and its inlet is connected to a water source. The water delivery hose is connected to the water pump's outlet.

Both sets of nozzles are installed on the water delivery hose, and multiple sets of nozzles are respectively installed on the two sets of water distributors. When the water pump is started, clean water is delivered to the cavity of the mixing chamber through the water delivery hose. After the material in the feeding hopper is discharged, the corresponding control valve is opened, and the water delivery hose delivers clean water to the water distributor. The multiple sets of nozzles spray clean water to rinse the screen.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the water supply mechanism first delivers a certain amount of water to the mixing mechanism, and then the aggregate and powder are respectively delivered to two sets of feeding mechanisms. The feeding mechanism screens the aggregate, and the batching mechanism delivers the materials to the mixing mechanism in batches. The stirring mechanism is started to stir the materials while dispersing them, thus enhancing the mixing effect. After the materials in the feeding mechanism are completely discharged, the water supply mechanism sprays water into the two sets of feeding mechanisms to rinse them and deliver clean water to the mixing mechanism, which facilitates the formation of concrete. The discharge mechanism stirs the materials at the discharge port, which enhances the overall fluidity of the concrete and facilitates its discharge through the mixing mechanism after the concrete is mixed.
