Description

Technical Field

[0001] This utility model relates to the field of concrete processing equipment technology, and in particular to a concrete mixing device for building construction. Background Technology

[0002] A concrete mixing plant is a type of mechanical equipment used in the construction industry. It is mainly used to mix raw materials such as cement, sand, gravel, and water in a certain proportion to produce uniform concrete. It is widely used in the construction of infrastructure such as bridges, roads, high-rise buildings, and dams. With the development of construction technology, the requirements for concrete mixing plants are also constantly increasing. The future development trend will be more efficient, intelligent, and environmentally friendly mixing equipment.

[0003] Currently, concrete is the most commonly used building material in construction. Depending on construction needs, concrete can be processed and shaped into various concrete components. Concrete is a mixture of cementitious materials, aggregates, and water in a specific ratio, and admixtures and additives can be added. Therefore, concrete needs to be pre-mixed before use.

[0004] However, concrete mixing equipment still has the following drawbacks. Traditional concrete mixing equipment has a relatively simple structural design and often uses a motor to drive the mixing device. It mixes by directly driving the mixing blades. This direct driving method is prone to interference between the mixing blades, thereby reducing the mixing efficiency and also hindering the uniform distribution of materials inside the mixing drum. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a concrete mixing device for building construction, so as to solve the following shortcomings of the existing concrete mixing device. The traditional concrete mixing device has a relatively simple structural design and mostly uses a motor to drive the mixing device. The mixing is carried out by directly driving the mixing blades. This direct driving method is prone to interference between the mixing blades, thereby reducing the mixing efficiency. It is also not conducive to the uniform distribution of materials inside the mixing drum.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A concrete mixing device for building construction includes: a processing cylinder, a feeding mechanism on one side of the processing cylinder, and a mixing mechanism inside the processing cylinder;

The two stirring blades are fixedly installed on the outside of the driven shaft, and the top end of the driven shaft is movably inserted into the inside of the top plate. The top plate is fixedly installed on the outside of the drive shaft.

[0009] Furthermore, a support leg is fixedly installed at the bottom of the processing cylinder, and a foot pad is fixedly installed at the bottom end of the support leg.

[0010] Furthermore, the feeding mechanism includes a feeding trough, a conveying box, a synchronous motor, a screw conveying shaft, screw conveying blades, a connecting pipe, and a connecting rod. One end of the connecting rod is fixedly connected to the outer wall of the processing cylinder, and the other end of the connecting rod is fixedly connected to one side of the outer wall of the conveying box.

[0011] Furthermore, a feed hole is opened inside one side wall of the bottom of the conveyor box, and a feed trough is fixedly installed on one side outer wall of the conveyor box and located outside the feed hole.

[0014] The beneficial effects of this utility model are:

[0015] Equipped with a mixing mechanism, the processing drum serves as the main container for holding concrete materials during the mixing process. The feeding mechanism is responsible for delivering the concrete materials into the processing drum. In use, the drive motor is turned on, causing the rotating plate to drive the driven shaft to rotate as a whole. Through the meshing of the driven gear and the gear ring, the driven shaft rotates as a whole while rotating itself.

[0026] Please see Figure 1-4 As shown, a concrete mixing device for building construction includes: a processing cylinder 1, a feeding mechanism on one side of the processing cylinder 1, and a mixing mechanism inside the processing cylinder 1.

[0027] The stirring mechanism includes a drive mechanism, a driven shaft 13, a driven gear 19, and stirring blades 16. The drive mechanism includes a drive motor 21, a drive shaft 20, a top plate 17, a gear ring 22, and a rotating plate 11. The drive motor 21 is fixedly installed at the bottom of the processing cylinder 1, and its output end is fixedly connected to the drive shaft 20. The rotating plate 11 is fixedly sleeved on the outside of the drive shaft 20, and its outer wall is embedded inside the side wall of the processing cylinder 1. The gear ring 22 is fixedly installed at the bottom of the rotating plate 11. The bottom end of the driven shaft 13 is movably limited and inserted into the interior of the rotating plate 11. The driven gear 19 is fixedly sleeved on the outside of the bottom end of the driven shaft 13. The driven gear 19 and... The gear ring 22 is engaged and installed. The stirring blade 16 is fixedly installed on the outside of the driven shaft 13. The top end of the driven shaft 13 is movably inserted into the inside of the top plate 17. The top plate 17 is fixedly installed on the outside of the drive shaft 20. The stirring mechanism also includes a mounting frame, a movable shaft 14, a scraper 18, a vertical plate 15, and a stirring blade 12. The mounting frame is fixedly installed on the outside of the drive shaft 20. Both ends of the movable shaft 14 are movably inserted into the inside of the mounting frame. The stirring blade 12 is fixedly installed on the outside of the movable shaft 14. The vertical plate 15 is fixedly installed on one side of the outer wall of the mounting frame. The scraper 18 is fixedly installed on the other side of the outer wall of the vertical plate 15. The scraper 18 is movably connected to the inner wall of the processing cylinder 1.

[0028] Specifically, by incorporating a mixing mechanism, the processing drum 1 serves as the main container for holding the concrete materials during the mixing process. A feeding mechanism delivers the concrete materials into the processing drum 1. During operation, the drive motor 21 is turned on, causing the rotating plate 11 to drive the driven shaft 13 to rotate. This is achieved through the meshing of the driven gear 19 and the gear ring 22, allowing the driven shaft 13 to rotate simultaneously with itself. This, in turn, drives the first mixing blade 12 to rotate, effectively mixing the concrete. Combined with the vertical rotation of the second mixing blade 16, this results in more uniform and reliable concrete mixing, higher mixing efficiency, and benefits the mixing drum. The uniform distribution of the material is achieved by the drive shaft 20 driving the mounting frame to be fixed on the drive shaft 20, allowing the movable shaft 14 to rotate freely inside it. The mixing blade 12 is fixed on the movable shaft 14, ensuring that the blade is in close contact with the concrete during rotation. Under the action of different resistances, the blade acts as a driving force, causing the mixing blade 12 to rotate around the movable shaft 14, thereby achieving vertical rotation, increasing the diversity of mixing methods and improving mixing efficiency. The scraper 18 is fixed on the other side of the vertical plate 15 and contacts the inner wall of the processing cylinder 1. It can remove the adhering substances on the cylinder wall during mixing, keeping the inner wall of the cylinder clean. It can also be used to clean the processing cylinder 1 after mixing, facilitating secondary use.

[0029] In this embodiment, a support leg 2 is fixedly installed at the bottom of the processing cylinder 1, a foot pad 3 is fixedly installed at the bottom end of the support leg 2, a water inlet is fixedly installed at the top of the processing cylinder 1, and a discharge pipe 4 is fixedly installed inside the bottom side wall of the processing cylinder 1. A valve is installed inside the discharge pipe 4.

[0030] Specifically, the device is powered by an external power source, and an external controller is connected to the device. The controller is electrically connected to the motor. Other auxiliary materials or water required for processing can be added into the processing cylinder 1 through the water inlet.

[0031] The feeding mechanism includes a feeding trough 7, a conveying box 8, a synchronous motor 6, a screw conveyor shaft 23, screw conveyor blades 24, a connecting pipe 9, and a connecting rod 5. One end of the connecting rod 5 is fixedly connected to the outer wall of the processing cylinder 1, and the other end of the connecting rod 5 is fixedly connected to the outer wall of one side of the conveying box 8. A feeding hole is opened inside the bottom side wall of the conveying box 8, and a feeding trough 7 is fixedly installed on the outer wall of one side of the conveying box 8 and located outside the feeding hole. The synchronous motor 6 is fixedly installed at the bottom of the conveying box 8, and the output end of the synchronous motor 6 is fixedly connected to the screw conveyor shaft 23. The screw conveyor blades 24 are fixedly sleeved on the outside of the screw conveyor shaft 23 and located inside the conveying box 8. One end of the connecting pipe 9 is connected to the top of the conveying box 8, and the other end of the connecting pipe 9 is connected to the processing cylinder 1.

[0032] Specifically, in use, concrete raw materials are added into the conveying box 8 through the feeding trough 7 and the feeding hole. The synchronous motor 6 drives the spiral conveying shaft 23 to rotate, so that the material moves forward step by step along the spiral conveying blades 24 in the conveying box 8, and finally is poured into the processing cylinder 1 through the connecting pipe 9. The conveying box 8 is set at an incline, which facilitates the feeding of concrete. There is no need to climb up and down to feed the material, which is very convenient and quick.

[0033] In summary, compared with existing technologies, this concrete mixing mechanism has at least the following beneficial effects: By incorporating a mixing mechanism, the processing drum 1 serves as the main container for holding the concrete materials during the mixing process. The feeding mechanism is responsible for delivering the concrete materials into the processing drum 1. During use, turning on the drive motor 21 causes the rotating plate 11 to drive the driven shaft 13 to rotate as a whole. This is achieved through the meshing of the driven gear 19 and the gear ring 22, allowing the driven shaft 13 to rotate simultaneously with itself. This, in turn, drives the first mixing blade 12 to rotate, effectively mixing the concrete. Combined with the vertical rotation of the second mixing blade 16, this results in more uniform and reliable concrete mixing. Higher efficiency and better uniform distribution of materials inside the mixing drum. The drive shaft 20 drives the mounting frame to be fixed on the drive shaft 20, allowing the movable shaft 14 to rotate freely inside it. The mixing blade 12 is fixed on the movable shaft 14, ensuring that the blade is in close contact with the concrete during rotation. Under the action of different resistances, it acts as a driving force, causing the mixing blade 12 to rotate around the movable shaft 14, thereby achieving vertical rotation, increasing the diversity of mixing methods and improving mixing efficiency. The scraper 18 is fixed on the other side of the vertical plate 15 and contacts the inner wall of the processing drum 1. It can remove the adhering substances on the drum wall during mixing, keeping the inner wall of the drum clean. It can also clean the processing drum 1 after mixing, making it convenient for secondary use.

Therefore, the protection scope of this utility model should be determined by the scope of the claims.
