[0002] Concrete is an artificial stone material made by mixing cementitious materials, aggregates, water, and, when necessary, admixtures and additives in appropriate proportions, followed by stirring, molding, curing, and hardening. It is one of the most widely used building materials in modern construction engineering. Concrete processing equipment refers to the general term for various machines and equipment used in the production, mixing, transportation, pouring, molding, curing, and post-processing of concrete. Together, they constitute a complete processing system for concrete from raw materials to the final product, ensuring efficient and high-quality construction of concrete projects.

[0003] A search revealed Chinese Patent Publication No. CN205766819U, which discloses a concrete processing equipment, including a concrete mixing silo and a concrete processing device. The concrete processing device has a discharge port on its lower right, a feeding silo on its upper left, and a water feeding silo on its upper right. The concrete mixing silo is installed inside the concrete processing device. A water flow conduit is located on the rotating shaft corresponding to the water inlet pipe. An electric motor is installed on the left side of the concrete processing device corresponding to the rotating shaft. The beneficial effects of this invention are: Firstly, the concrete processing equipment has a water flow conduit on the rotating shaft, with the water inlet directly connected to the water flow conduit. Combined with the water outlet pipe on the hollow mixing rod, the internal water supply method allows for faster water penetration into the concrete, improving the efficiency of concrete processing.

[0004] The aforementioned patent specification mentions that "the concrete processing equipment firstly has a water flow pipe on the rotating shaft, the water inlet chamber is directly connected to the water flow pipe, and then, in conjunction with the water outlet pipe on the hollow mixing rod, uses an internal water supply method to make the water in the concrete penetrate faster, thus improving the efficiency of concrete processing."

In severe cases, it can even jam the entire machine, affecting its service life. Furthermore, a large amount of concrete sticks to the mixer during the mixing process, affecting its mixing efficiency.

[0031] Example: A concrete processing equipment, referring to Figure 1 , Figure 3 and Figure 4 The system includes a mixing tank 1 and a water storage tank 3. The mixing tank 1 serves as the core container for concrete processing and its main function is to provide a mixing space for concrete raw materials. The water storage tank 3 is used to store water for cleaning. A cleaning mechanism 2 is fixedly connected to the bottom of the mixing tank 1.

[0032] The drive assembly 22 is externally fixedly connected to a grooved column 23, which serves to fix the mixing blades 24 and transmit power, while guiding the flow of stones. Multiple mixing blades 24 are externally fixedly connected to the grooved column 23, which serve to mix concrete raw materials. The working principle is that they rotate with the grooved column 23. The guide grooves on the outside and the inclined placement can promote the flow of materials and enhance the collision and mixing between materials.

Multiple short scrapers 28 are fixedly connected to the outside of the ring 26. Their function is to clean the upper and middle areas of the inner wall of the mixing tank 1. The working principle is that as the ring 26 rotates, its shorter length adapts to the curvature of the upper part of the tank wall, scraping away concrete residue in this area. A water pumping assembly 29 is fixedly connected to the top of the water storage tank 3. Its function is to transport water from the water storage tank 3 to the mixing tank 1 for cleaning. The water pumping assembly 29 includes a water pump 291, which provides pumping power.

The bottom of the water pump 291 is fixedly connected to the top of the water storage tank 3, and the output end of the water pump 291 is fixedly connected to the transport pipe 292, which is used to transport water. The outside of the transport pipe 292 is fixedly connected to the spray head 293, which is used to spray water onto the inner wall of the mixing tank 1 in the form of a spray. Its working principle is to disperse the water flow into fine water columns or water mist through the internal porous structure, so as to evenly cover the tank wall. Specifically, the mixing drum 1 serves as the core container, providing a dedicated space for mixing concrete raw materials and ensuring the orderly conduct of mixing operations. The water storage tank 3 is specifically for storing cleaning water, facilitating equipment cleaning operations. In the bottom cleaning mechanism 2, the protective shell 21 effectively isolates the concrete, water, and external dust and impurities inside the mixing drum 1, protecting the internal drive component 22 from contamination and damage. The motor 221 of the drive component 22 provides rotational power, and the rotating shaft 222 efficiently transmits power, ensuring the stable operation of the cleaning mechanism 2. Overall, this improves the practicality, durability, and ease of maintenance of the equipment.

[0033] A lifting assembly 210 is fixedly connected to the outside of the mixing tank 1. The lifting assembly 210 includes a fixed plate a2101, which is used to install and fix a cylinder 2102. Its function is to provide extension and retraction power to adjust the angle of the mixing tank 1. The working principle is that compressed air drives an internal piston, causing the telescopic shaft 2103 to extend or retract. The fixed plate a2101 is fixedly connected to the outside of the mixing tank 1. A rotating plate 211 is rotatably connected to the outside of the lifting assembly 210. A fixing ring 212 is fixedly connected to the outside of the rotating plate 211. A gas cylinder is fixedly connected to the top of the fixed plate a2101. Cylinder 2102, the drive end of cylinder 2102 is fixedly connected to telescopic shaft 2103, the function of which is to transmit the telescopic power of cylinder 2102. The working principle is that it telescopically extends and retracts with the piston movement of cylinder 2102. The power is transmitted to rotating plate 211 through ball 2104. The top of telescopic shaft 2103 is rotatably connected to ball 2104, the function of which is to realize multi-angle rotation. The outside of ball 2104 is rotatably connected to the inside of rotating plate 211. The lower outside of grooved column 23 is fixedly connected to anti-jamming disc 213, the function of which is to prevent stones from getting stuck between the bottom of mixing tank 1 and grooved column 23. Specifically, the lifting component 210 enables flexible adjustment of the angle of the mixing tank 1, the fixed plate a securely mounts the cylinder 2102, the cylinder 2102 uses compressed air to drive the telescopic shaft 2103 to extend and retract, and with the multi-angle rotation function of the ball 2104, the power is efficiently transmitted to the rotating plate 211, realizing convenient adjustment of the angle of the mixing tank 1. The fixed ring 212 works with the rotating plate 211 to ensure structural stability, and the anti-jamming disc 213 can effectively prevent stones from getting stuck between the bottom of the mixing tank 1 and the groove column 23, avoiding jamming that affects the operation of the equipment, and improving the overall operational flexibility, operational stability and practicality of the equipment.

[0034] Reference Figure 2 , Figure 5 and Figure 6The mixing drum 1 has a fixed internal discharge port 4 for discharging the mixed concrete. After mixing, the baffle 54 is opened, and the concrete flows out from the discharge port 4 under gravity. The mixing drum 1 also has a fixed external metering mechanism 5, which includes a fixed plate b51. The fixed mechanism works by using an internal threaded structure to engage with a threaded post 521, providing stable support and an adjustment base for the opening / closing assembly 52. ​​The fixed plate b51 is externally fixed to the outside of the mixing drum 1, and its internal and external threads are connected to... The opening and closing assembly 52 includes a threaded post 521, which is used to achieve axial movement by rotation. The external thread of the threaded post 521 is connected to the inside of the fixed plate b51. The bottom of the threaded post 521 is fixedly connected to a limit post 522, which is used to connect the threaded post 521 and the limit block 523 and restrict the rotation of the baffle 54. The external rotatably connected to the limit block 523 is used to cooperate with the limit post 522 to restrict the rotational freedom of the baffle 54. The external fixed connection of the limit block 523 is to the outside of the connecting post b53. Specifically, after mixing, the discharge port 4 can discharge concrete by opening the baffle 54 and using gravity, thus achieving convenient concrete discharge. The fixed plate b of the metering mechanism 5 provides stable support and adjustment base for the opening and closing component 52 through the threaded structure. The threaded column 521 achieves axial movement by rotation, and together with the limiting column 522 and the limiting block 523, it restricts the rotational freedom of the baffle 54, ensuring that the opening and closing of the baffle 54 is controllable, which facilitates the control of the concrete discharge amount, improves the convenience and quantitative accuracy of the discharge operation, and enhances the flexibility and practicality of the equipment.

[0035] The opening and closing component 52 is externally fixedly connected to a connecting column b53, which is used to transmit the displacement of the opening and closing component 52. The working principle is that it moves up and down with the limit block 523, driving the baffle 54 to move synchronously. The connecting column b53 is externally fixedly connected to a baffle 54, which is used to control the opening and closing and the opening degree of the discharge port 4. The working principle is that it moves up and down along the groove, changing the coverage area with the discharge port 4. The baffle 54 is externally slidably connected to the inner groove of the mixing tank 1, and the inner groove of the mixing tank 1 is slidably connected to the outer side of the baffle 54. Specifically, the connecting column b can move up and down with the limiting block 523, accurately transmitting the displacement of the opening and closing component 52 to the baffle 54, so that the two move synchronously; the baffle 54 changes the coverage area with the discharge port 4 by sliding along the groove inside the mixing tank 1, thereby flexibly controlling the opening and closing and the size of the opening of the discharge port 4, which is convenient to adjust the concrete discharge amount according to the needs. The overall design makes the discharge control more precise and the operation more convenient, improving the quantitative discharge capacity and the flexibility of use of the equipment.

[0036] The implementation principle of this application embodiment is as follows: First, the motor 221 is started to drive and rotate the rotating shaft 222, causing the rotating shaft 222 to drive the grooved column 23 to rotate synchronously. This causes the multiple externally fixed stirring blades 24 to rotate accordingly. Because the stirring blades 24 have guide grooves on their exterior and are placed at an angle, and the grooved column 23 also has multiple guide grooves on its exterior, the raw materials such as stones fed into the mixing tank 1 can be guided to flow during rotation. Meanwhile, the anti-jamming disc 213 at the bottom of the grooved column 23 rotates synchronously with it, preventing stones from getting stuck between the bottom of the mixing tank 1 and the grooved column 23. The connecting column a25 at the top of the grooved column 23 rotates with the grooved column 23, causing the ring 26 to rotate, thus... Multiple long scrapers 27 at the bottom of the ring 26 and multiple short scrapers 28 on the outside rotate synchronously. The long scrapers 27 act on the inner wall of the mixing tank 1, and the short scrapers 28 act on the top edge of the mixing tank 1. When the agitator needs to be cleaned, the water pump 291 of the water storage tank 3 is started to pump out the water in the water storage tank 3, so that the transport pipe 292 delivers it to the spray head 293. At the same time, the cylinder 2102 is started to drive the telescopic shaft 2103 to extend and retract. The ball 2104 at the top of the telescopic shaft 2103 rotates inside the rotating plate 211, driving the rotating plate 211 and the external fixing ring 212 to move, thereby adjusting the tilt angle of 293 and cleaning the mixing tank 1 and the agitator from all directions.

[0037] After mixing, the threaded column 521 is rotated to move up and down inside the fixed plate b51, causing the threaded column 521 to drive the bottom limiting column 522 to move synchronously. As a result, the limiting column 522 drives the limiting block 523 to move up and down within the range of the fixed plate b51. The limiting block 523 drives the baffle 54 to slide in the groove inside the mixing tank 1 through the connecting column b53, changing the size of the gap between the baffle 54 and the discharge port 4. The concrete then flows out from the gap, thus adjusting the discharge amount.
