Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and in particular to an auxiliary feeding mechanism for concrete production. Background Technology

[0002] Traditional concrete production typically involves directly conveying various raw materials into the mixing equipment via pipelines. While simple to operate, this method has significant drawbacks. Because the raw materials enter the mixing equipment directly without adequate pre-mixing, uneven mixing is easily achieved. For example, cement may accumulate in localized areas, while additives may be unevenly distributed, negatively impacting the strength and durability of the concrete.

[0003] In addition, the traditional feeding method has low mixing efficiency. During the mixing process, it takes a long time for various raw materials to reach a uniform distribution, which not only increases production time but also reduces production efficiency. Moreover, due to insufficient mixing, multiple stirrings may be required to achieve the desired effect, further increasing energy consumption and production costs. To address these issues, we propose an auxiliary feeding mechanism for concrete production. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary feeding mechanism for concrete production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary feeding mechanism for concrete production includes a conveying box, with a discharge pipe connected to the lower end of the conveying box. A protective box is fixed to one side of the upper end of the conveying box, and a rotating device is installed inside the protective box. A mixing mechanism and a spray pipe are installed on the rotating device. The upper ends of the spray pipe and the mixing mechanism are rotatably sleeved on the upper end of the conveying box. The mixing mechanism is located in the middle of the conveying box, and the spray pipe is located on one side of the conveying box. One end of the spray pipe is connected to an air supply mechanism, and a dispensing pipe is connected to one side of the upper end of the conveying box.

[0007] Preferably, the rotating device includes a drive motor fixed inside a protective box, and sprockets are fixedly fitted on the upper end of the nozzle and the end of the output shaft of the drive motor. A chain meshes between the two sprockets, and multiple spray holes are provided at equal intervals on one side of the nozzle.

[0008] Preferably, the stirring mechanism includes a stirring rod connected to the end of the output shaft of the drive motor, the stirring rod being rotatably sleeved on the upper end of the conveyor box, and a plurality of spiral stirring blades being fixed at equal intervals around the circumference of the stirring rod.

[0009] Preferably, the air delivery mechanism includes a rotary joint connected to the upper end of the nozzle, the rotary joint being rotatably sleeved on the upper end of the protective box, the upper end of the rotary joint being connected to an air delivery pipe, a fixing frame being fixed on one side of the delivery box, an air pump being installed on the fixing frame, and one end of the air delivery pipe being connected to one side of the air pump.

[0010] Preferably, a mounting plate is fixed around the lower end of the discharge pipe, and four screws are evenly spaced through the mounting plate.

[0011] Preferably, an exhaust pipe is connected to one side of the conveying box, and a filter screen is installed inside the exhaust pipe.

[0012] In this utility model, during concrete production:

[0013] 1. Raw material feeding: When feeding concrete, first put all the raw materials that need to be added into the conveyor box through the feeding pipe;

[0014] 2. Mixing and air supply: Start the drive motor in the protection box. The output shaft of the drive motor drives the sprocket to rotate. Through the chain transmission, the nozzle starts to rotate. At the same time, the output shaft of the drive motor also drives the stirring rod to rotate. The spiral stirring blades on the stirring rod mix the raw materials in the conveying box. During the rotation of the nozzle, the air pump starts to work, delivering air into the nozzle through the air supply pipe and rotary joint. Then, the air is sprayed out through the nozzle holes on the nozzle to further promote the mixing of the raw materials.

[0015] 3. Raw material discharge: After the raw materials have been fully stirred and mixed in the conveying box, open the electric valve on the discharge pipe. The lower end of the discharge pipe is fixed to the upper end of the mixing tank by the mounting plate and screws. The mixed raw materials enter the mixing tank through the discharge pipe for further thorough and uniform mixing.

[0016] 4. Gas emission: Throughout the process, the gas generated inside the conveying box is discharged through the exhaust pipe. The filter screen installed inside the exhaust pipe can prevent raw material particles from being discharged with the gas, thus playing a role in environmental protection and preventing raw material waste.

[0017] This utility model has the following advantages:

[0018] 1. Through the synergistic action of the mixing mechanism and the nozzle, the raw materials are fully premixed in the conveying box. The rotation of the mixing rod and the spiral mixing blades can fully agitate the raw materials, while the gas sprayed from the nozzle further breaks up the aggregated state of the raw materials, so that the various raw materials can be more evenly distributed, thereby improving the quality of concrete.

[0019] 2. The pre-mixing process reduces the mixing time of raw materials in the mixing tank, enabling the mixing tank to complete the final mixing process more quickly. This not only shortens the production cycle but also improves production efficiency, meeting the needs of large-scale construction.

[0020] 3. Since the raw materials have been fully mixed in the conveyor box, the stirring time and energy consumption required for the final mixing in the mixing tank are reduced accordingly, which helps to reduce production costs and improve the economic benefits of enterprises.

[0021] In summary, this invention, through the synergistic action of the mixing mechanism and the spray nozzle, ensures that the raw materials are fully premixed in the conveying box, allowing for a more uniform distribution of various raw materials and thus improving the quality of concrete. The premixing process reduces the mixing time of the raw materials in the mixing tank, enabling the mixing tank to complete the final mixing process more quickly. This not only shortens the production cycle but also improves production efficiency, meeting the needs of large-scale construction projects. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-3 An auxiliary feeding mechanism for concrete production includes a conveying box 9, with a discharge pipe 6 connected to the lower end of the conveying box 9. A protective box 2 is fixed to one side of the upper end of the conveying box 9. A rotating device is installed inside the protective box 2. A mixing mechanism and a spray pipe 12 are installed on the rotating device. The rotation of the spray pipe 12 can cause gas to be sprayed out at different positions inside the conveying box 9, thereby expanding the range of action of the gas and improving the mixing effect.

[0028] The upper ends of the nozzle 12 and the stirring mechanism are rotatably sleeved on the upper end of the conveying box 9. The stirring mechanism is located in the middle of the conveying box 9, and the nozzle 12 is located on one side of the conveying box 9. One end of the nozzle 12 is connected to the gas supply mechanism. The upper side of the conveying box 9 is connected to the feeding pipe 1. Electric valves are installed on both the feeding pipe 1 and the discharge pipe 6. The use of electric valves makes the raw material discharge process more automated and controllable. Operators can accurately control the discharge time and flow rate according to the actual production situation, which improves the flexibility and efficiency of production.

[0029] The rotating device includes a drive motor 13 fixed inside the protective box 2. Sprockets 18 are fixedly mounted on the upper end of the nozzle 12 and the output shaft end of the drive motor 13. A chain 14 meshes between the two sprockets 18. Multiple nozzle holes 17 are provided at equal intervals on one side of the nozzle 12. The sprocket-chain transmission method has the characteristics of high transmission efficiency and good stability. It can accurately transmit the power of the drive motor 13 to the nozzle 12, ensuring that the nozzle 12 can rotate according to the design requirements. The nozzle holes 17 can make the sprayed gas evenly distributed in the conveying box 9, better promoting the mixing of raw materials. The sprayed gas can break the agglomeration between raw materials, making the raw materials more dispersed and further promoting the mixing of raw materials.

[0030] The stirring mechanism includes a stirring rod 16 connected to the end of the output shaft of the drive motor 13. The stirring rod 16 is rotatably sleeved on the upper end of the conveyor box 9. Multiple spiral stirring blades 15 are fixed at equal intervals around the stirring rod 16. During the stirring process, the spiral stirring blades 15 can not only mix the raw materials in the horizontal direction, but also produce an up-and-down tumbling effect in the vertical direction, which greatly improves the uniformity and efficiency of stirring and can more fully mix various raw materials together.

[0031] The gas delivery mechanism includes a rotary joint 11 connected to the upper end of the nozzle 12. The rotary joint 11 is rotatably sleeved on the upper end of the protective box 2. The upper end of the rotary joint 11 is connected to the gas delivery pipe 3. A fixed frame 5 is fixed on one side of the delivery box 9. An air pump 4 is installed on the fixed frame 5. One end of the gas delivery pipe 3 is connected to one side of the air pump 4. The compressed air provided by the air pump 4 is delivered to the nozzle 12 through the gas delivery pipe 3 and the rotary joint 11, providing additional power for the mixing of raw materials.

[0032] A mounting plate 7 is fixed around the lower end of the discharge pipe 6. Four screws 8 are evenly spaced through the mounting plate 7. The mounting plate 7 and screws 8 enable the discharge pipe 6 to be securely connected to the upper end of the mixing tank, ensuring that there will be no loosening or leakage during the discharge of raw materials, thus improving the stability and safety of the equipment operation.

[0033] An exhaust pipe 10 is connected to one side of the conveyor box 9. A filter screen is installed inside the exhaust pipe 10. The filter screen can effectively intercept raw material particles and prevent them from being discharged with the gas, which is both environmentally friendly and prevents waste of raw materials.

[0034] In this utility model, during concrete production:

[0035] 1. Raw material feeding: When feeding concrete, first put all the raw materials that need to be added into the conveying box 9 through the feeding pipe 1;

[0036] 2. Stirring and air supply: Start the drive motor 13 in the protection box 2. The output shaft of the drive motor drives the sprocket 18 to rotate. Through the transmission of the chain 14, the nozzle 12 starts to rotate. At the same time, the output shaft of the drive motor also drives the stirring rod 16 to rotate. The spiral stirring blades 15 on the stirring rod stir the raw materials in the conveying box 9. During the rotation of the nozzle 12, the air pump 4 starts to work, and delivers air into the nozzle 12 through the air supply pipe 3 and the rotary joint 11. Then, it is sprayed out through the nozzle hole 17 on the nozzle to further promote the mixing of the raw materials.

[0037] 3. Raw material discharge: After the raw materials have been fully stirred and mixed in the conveying box 9, the electric valve on the discharge pipe 6 is opened. The lower end of the discharge pipe 6 is fixed to the upper end of the mixing tank by the mounting plate 7 and screws 8. The mixed raw materials enter the mixing tank through the discharge pipe 6 for further thorough and uniform mixing.

[0038] 4. Gas emission: During the entire process, the gas generated in the conveying box 9 is discharged through the exhaust pipe 10. The filter screen installed in the exhaust pipe can prevent raw material particles from being discharged with the gas, which plays a role in environmental protection and preventing raw material waste.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto.
