Description

Technical Field

[0001] This invention relates to the field of cement concrete mixing technology, specifically to a cement concrete mixing device with material feeding control function. Background Technology

[0002] In the field of construction engineering, cement concrete is an important building material, and its quality directly affects the safety and durability of construction projects. The preparation of cement concrete usually relies on cement concrete mixing equipment, which produces concrete that meets the requirements of the project by precisely controlling the proportion and mixing process of raw materials such as cement, sand, gravel, and water.

[0003] Traditional cement concrete mixing plants often encounter numerous problems during the material feeding process. On the one hand, due to the lack of a precise material feeding control mechanism, it is difficult to accurately control the amount of raw materials such as cement and sand, which can easily lead to deviations in the concrete mix proportions, thereby affecting the strength, durability, and other properties of the concrete.

[0004] According to the description in the patent announcement (authorization announcement number: CN219563631U) of a cement mortar mixing device for preventing sedimentation, the cement mortar mixing device for preventing sedimentation includes "mixing device, motor" etc., to realize the mixing work.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This anti-settling cement mortar mixing device uses a mixing unit and motor to perform the mixing work. When using this device, the materials are directly put into the mixing unit for stirring. During the material input process, due to the lack of a precise material feeding control mechanism, it is difficult to accurately control the amount of raw materials such as cement and sand, which can easily lead to deviations in the concrete mix ratio, thereby affecting the strength, durability and other properties of the concrete. Therefore, this device needs to be improved. Summary of the Invention

[0010] Preferably, the mixing tank is fixedly connected to the top of the processing table, the rotating shaft is rotatably connected to the inside of the mixing tank, the left side of the cleaning frame is in contact with the inside of the mixing tank, and the left side of the cleaning frame is triangular, which facilitates the cleaning of the material attached to the inside of the mixing tank under the action of the cleaning frame.

[0011] Preferably, the feeding pipe extends through the inside of the processing table, and the bottom of the hopper is fixedly connected to the top of the mixing tank, so as to facilitate the storage of materials required for cement concrete through the hopper.

[0012] Preferably, the hopper, fixing frame, first cylinder and baffle are provided in two sets, and the two sets of hopper, fixing frame, first cylinder and baffle are symmetrically distributed inside the fixing frame, so that different materials required for cement concrete can be stored separately by setting two sets.

[0013] Preferably, there are two sets of fixing plates and weight sensors, which are symmetrically distributed on the front side of the mounting base, so that the required amount of material can be controlled by the weight sensors.

[0014] Preferably, the water spraying mechanism includes a water tank, which is fixedly connected to the top of the processing table. A conveying pipe is fixedly connected to the right side of the water tank. A pump body is fixedly connected to the periphery of the conveying pipe.

A second nozzle is fixedly connected to the bottom of the first nozzle.

[0015] Preferably, the pump body is fixedly connected to the top of the processing table, and the first nozzle is fixedly connected to the inside of the mixing tank, so that the water in the water tank can be transported to the water storage tank through the conveying pipe via the pump body.

[0017] Preferably, there are two sets of tamping rods, which are symmetrically distributed on the left and right sides of the bottom of the mounting plate. The two sets of tamping rods are slidably connected to the two sets of hoppers, so that the materials stored in the hoppers can be tamped and dispersed by the tamping rods to avoid the raw materials from clumping.

[0018] Compared with the prior art, the present invention provides a cement concrete mixing device with material feeding control function, which has the following beneficial effects:

[0019] 1. This cement concrete mixing device with material feeding control function, through its set mixing mechanism, firstly feeds cement through the top of the mixing tank when cement concrete needs to be mixed, and then feeds the required materials into two hoppers. Through two sets of symmetrically distributed hoppers, a fixed frame, a first cylinder, and a baffle, the feeding of different materials can be controlled separately. The first cylinder pushes the baffle to slide in the hopper, which can flexibly adjust the size of the feeding port and achieve precise control of the material flow. With the help of two sets of weight sensors installed inside the fixed plate, the weight of the feeding material is monitored in real time. According to the set proportion parameters, the second cylinder pushes the fixed plate to precisely control the amount of material fed, effectively ensuring the proportion accuracy of cement concrete and improving the stability of finished product quality. When the material enters the mixing tank, the servo motor drives the rotating shaft and mixing rod to rotate at high speed, which can quickly and evenly mix cement concrete. The cleaning frame around the rotating shaft moves synchronously. Its left side is in close contact with the inner side of the mixing tank and is triangular, which can scrape off the material adhering to the inner wall of the mixing tank in time during the mixing process to avoid material residue.

[0020] 2. This cement concrete mixing device with material feeding control function uses a spray mechanism to store water in a water tank. The water is then pumped through a delivery pipe to a water storage tank, and then sprayed evenly into the mixing tank by a first and second nozzle fixed inside the mixing tank. This allows for the addition of the required water during the cement concrete mixing process. The multi-nozzle design ensures that the water and materials are fully in contact and mixed, avoiding concrete quality problems caused by uneven local water distribution. Furthermore, the second nozzle allows for convenient rinsing of materials adhering to the inside of the mixing tank during subsequent cleaning.

[0021] 3. This cement concrete mixing device with material feeding control function, through the set tamping mechanism, when storing the materials required for cement concrete under the action of the hopper, drives the mounting plate and tamping rod to move up and down in the hopper through the third cylinder. Under the action of the tamping rod, the material in the hopper is tamped to prevent the material from accumulating and blocking in the hopper, ensuring the smooth feeding of the material. At the same time, it can also tamp the material to avoid the phenomenon of material clumping, thereby ensuring the subsequent mixing effect. Attached Figure Description

[0038] Two sets of hoppers 25, fixing frames 291, first cylinders 293, and baffles 292 are provided. The two sets of hoppers 25, fixing frames 291, first cylinders 293, and baffles 292 are symmetrically distributed inside the fixing frame 24.

This allows the amount of material required to be controlled by the weight sensors 298.

[0039] Example 2

[0040] Please see Figure 1-8 Furthermore, based on Embodiment 1, the water spraying mechanism 3 includes a water tank 31, which is fixedly connected to the top of the processing table 1. A conveying pipe 33 is fixedly connected to the right side of the water tank 31. A pump body 32 is fixedly connected to the periphery of the conveying pipe 33.

[0041] The pump body 32 is fixedly connected to the top of the processing table 1, and the first nozzle 35 is fixedly connected to the inside of the mixing tank 22, so that the water in the water tank 31 can be transported to the water storage tank 34 through the conveying pipe 33 via the pump body 32.

[0042] Example 3

[0043] Please see Figure 1-8 Based on Examples 1 and 2, the material tamping mechanism 4 further includes a load-bearing frame 41, which is fixedly connected to the top of the fixed frame 24. A top plate 42 is fixedly connected to the top of the load-bearing frame 41, and a third cylinder 43 is fixedly connected to the top of the top plate 42. A mounting plate 44 is fixedly connected to the bottom of the third cylinder 43, and the mounting plate 44 is slidably connected to the inside of the load-bearing frame 41. A tamping rod 45 is fixedly connected to the bottom of the mounting plate 44 and is slidably connected to the inside of the hopper 25. Two sets of tamping rods 45 are provided, symmetrically distributed on the left and right sides of the bottom of the mounting plate 44, and the two sets of tamping rods 45 are slidably connected to the inside of the two hoppers 25, so that the material stored in the hopper 25 can be tamped and dispersed by the tamping rods 45, avoiding the caking of raw materials.

[0044] In actual operation, when this device is used to mix cement concrete, cement is first added through the top of the mixing tank 22, and the required materials are then added into the two hoppers 25. The first cylinder 293 moves the baffle 292, allowing the material to enter the top of the fixed plate 297. The weight sensor 298 weighs the required amount. When the set value is reached, the first cylinder 293 re-engages the baffle 292 to slide back into the hopper 25, stopping the material feeding. The first cylinder 293, baffle 292, fixed plate 297 and weight sensor 298 are respectively provided in two sets, which can control the material in the hopper 25 to achieve precise control of material flow. The two sets of weight sensors 298 can monitor the weight of the material in real time. When the required amount is on the top of the two fixed plates 297 and the weighing is completed, the second cylinder 295 can drive the mounting base 296 and fixed plate 297 to move, so that the bottom of the hopper 25 is opened, and the material can enter the mixing box 22.

[0045] When the material enters the mixing tank 22, the servo motor 26 drives the rotating shaft 27 and the stirring rod 29 to rotate at high speed, which can quickly and evenly stir the material to make it fully mixed. The cleaning frame 28 around the rotating shaft 27 moves synchronously. Its left side is in close contact with the inner side of the mixing tank 22 and is triangular. It can scrape off the material adhering to the inner wall of the mixing tank 22 in time during the mixing process to avoid material residue.

[0046] During the mixing process, the water tank 31 stores water, which is then pumped by the pump body 32 and transported to the water storage tank 34 through the delivery pipe 33. Water is then evenly sprayed into the mixing tank 22 by the first nozzle 35 and the second nozzle 36 fixed inside the mixing tank 22. This allows the necessary water to be added during the cement concrete mixing process. The multi-nozzle design ensures that the water and materials are fully in contact and mixed, avoiding concrete quality problems caused by uneven local water distribution. Furthermore, the second nozzle 36 allows for convenient rinsing of the materials adhering to the inside of the mixing tank 22 during subsequent cleaning, improving the cleaning effect and preventing material residue from affecting the quality of subsequent concrete mixing.

[0047] When the materials required for cement concrete are stored and prepared for feeding under the action of the hopper 25, the third cylinder 43 drives the mounting plate 44 and the tamping rod 45 to move up and down in the hopper 25. Under the action of the tamping rod 45, the materials in the hopper 25 are tamped to prevent the materials from accumulating and blocking in the hopper 25, ensuring the smooth feeding of the materials. At the same time, the materials can be broken up to avoid the formation of lumps, thereby ensuring the subsequent mixing effect. After the mixing is completed, the cement concrete can be fed through the feeding pipe 23.

[0048] In use, the servo motor 26, the first cylinder 293, the second cylinder 295, the third cylinder 43, the pump body 32 and the weight sensor 298 can be connected to the same PLC control system. The PLC control system is existing technology, and those skilled in the art are well aware of the specific operation methods and steps of this system. This case will not describe it in detail.

[0049] The weight sensor used in this case is model 298: BSS-5t.
