For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0029] See appendix Figures 1-5As shown in the figure, a concrete mixing moisture control system according to an embodiment of the present invention includes a support frame 1 and a moisture control component 2. A concrete mixer 101 is provided on the upper end of the support frame 1. The moisture control component 2 is located on the upper end of the concrete mixer 101 and its other end is connected to one end of the support frame 1. An external plate 301 is attached to one side of the support frame 1. A feed hopper 4 is slidably connected to the upper end of the external plate 301. An embedded ring 401 is fixedly installed on one end surface of the feed hopper 4. A hole is opened on the upper surface of the middle section of the feed hopper 4, and a microwave moisture sensor 7 is provided in the hole.

[0030] The embedded ring 401 can be inserted into one end of the inner wall of the feed inlet of the concrete mixer 101.

[0031] Support rods 3 are fixedly installed at both ends of the lower surface of the outer plate 301, and the support rods 3 can be fixed by bolts.

[0032] A snap-fit ​​block 5 is installed inside the hole of the feed hopper 4. A connecting block 6 is fixedly installed on one end of the upper surface of the inner wall of the snap-fit ​​block 5. The microwave moisture sensor 7 is fixedly connected to one end of the lower surface of the connecting block 6.

[0033] In the above technical solution, the moisture control component 2 and the microwave moisture sensor 7 in the feed hopper 4 work together to accurately detect the moisture required by the concrete raw materials, provide real-time data for the system, facilitate the controller 203 to accurately adjust the moisture, ensure stable concrete quality, and facilitate the use of a concrete mixing moisture control system.

[0034] To further improve the moisture control capability of the concrete mixer, the outer plate 301 expands the sliding space of the feed hopper 4, making it easier for workers to complete the feeding work. The feed hopper 4 is used to receive and transport concrete raw materials into the concrete mixer 101. The embedded ring 401 at one end of the feed hopper 4 can ensure a tight connection with the feed port of the concrete mixer 101 to prevent raw material leakage. Then, the internal microwave moisture sensor 7 can detect the moisture content of the feed material, and then water is injected through the moisture control component 2 to ensure that the moisture content of the concrete reaches the ideal state during mixing, reducing the tediousness of manual water addition, thereby improving the stability of moisture control.

[0035] See appendix Figure 4 As shown, a groove 303 is provided at one end of the upper surface of the outer plate 301, and a slider 305 is slidably installed in the groove 303. A threaded hole is provided at one end of the slider 305, and a lead screw 304 is threadedly connected in the threaded hole. A motor 302 is provided on one side of the outer plate 301. One end of the output shaft of the motor 302 is connected to one end of the lead screw 304. A linkage frame 306 is fixedly connected to one end of the upper surface of the slider 305. The feed hopper 4 is fixedly installed at one end of the upper surface of the linkage frame 306. A limit groove 402 is provided at one end of the upper surface of the embedded ring 401.

[0036] To improve stability during material feeding, the slider 305 slides linearly within the groove 303 via the lead screw 304, causing the feed hopper 4 on the linkage frame 306 connected to the upper surface to move. This allows the embedding ring 401 at one end of the feed hopper 4 to embed into the feed inlet of the concrete mixer 101, thereby ensuring accurate feeding and stability during material feeding, preventing material leakage, facilitating detection by the microwave moisture sensor 7, and making it easy to move. When not needed, the bolts inserted on the support rod 3 can be removed, allowing it to be moved away from the concrete mixer 101, reducing space occupation and facilitating the installation and maintenance of the microwave moisture sensor 7.

[0037] See appendix Figures 2 to 5 As shown, the moisture control component 2 includes a connecting frame 201, which is fixedly installed on one side of the support frame 1. A support plate 202 is fixedly connected to the other end of the connecting frame 201. The support plate 202 is located at the upper end of the concrete mixer 101. A water pump 204 and a controller 203 are respectively installed at both ends of the upper surface of the support plate 202. The controller 203 and the water pump 204 are connected by a signal connection. The controller 203 is wirelessly connected to a microwave moisture sensor 7. A water inlet pipe 206 is connected to the input end of the water pump 204. The other end of the water inlet pipe 206 is connected to a water tank 205, which is located at the lower end of the support frame 1. A water outlet pipe 210 is connected to the output end of the water pump 204. A reinforcing frame 207 is attached to one end of the lower surface of the water outlet pipe 210. The other end of the reinforcing frame 207 is fixedly connected to one end of the support plate 202. A nozzle 211 is installed at one end of the water outlet pipe 210, and the nozzle 211 is correspondingly positioned to correspond with the concrete mixer 101. A connecting rod 208 is fixedly connected to one end of the lower surface of the reinforcement frame 207. A limiting block 209 is fixedly installed at one end of the connecting rod 208. A groove is provided on one side of the limiting block 209, and the water outlet pipe 210 can be limited and fixed through the cooperation of the limiting block 209 and the limiting groove 402. The microwave moisture sensor 7 and the controller 203 are respectively model Hydro-MixVI and S7-200SMART, and the water pump 204 is model 75DWB60-5.

[0038] To improve moisture control during concrete mixing, a microwave moisture sensor 7 detects the moisture content of the concrete raw materials entering the feed hopper 4 in real time. The detected data is then wirelessly transmitted to a controller 203 located on the support plate 202. After receiving the moisture data from the microwave moisture sensor 7, the controller 203 analyzes and processes it according to a preset program and algorithm. If the detected moisture content does not meet the requirements for concrete mixing, the controller 203 connects to the water pump 204 via a signal connection, sending a command to the water pump 204. The input end of the water pump 204 is then connected to the water tank 205 located at the lower end of the support frame 1 via a water inlet pipe 206. After 204 is started, water is drawn from water tank 205. The water enters water outlet pipe 210 through the output end of water pump 204. Water outlet pipe 210 is fixed to one end of bearing plate 202 by reinforcing frame 207 to ensure the stability of water outlet pipe 210. The nozzle 211 at one end of water outlet pipe 210 is set to correspond to concrete mixer 101. Then water is sprayed into concrete mixer 101, thereby realizing the adjustment and control of water in the concrete mixing process. When controlling water, the feed hopper 4 is driven by screw 304 to move closer to one end of concrete mixer 101, so that the limiting groove 402 and limiting block 209 at one end of embedded ring 401 fit with water outlet pipe 210, improving the stability when water is discharged.

[0039] In this embodiment of the invention, when the motor 302 is working, its output shaft drives the lead screw 304 to rotate. Since the threaded hole on the slider 305 is threadedly connected to the lead screw 304, the lead screw 304 then drives the slider 305 to move within the slide groove 303. Simultaneously, the slider 305 moves, and the feed hopper 4 moves along with it via the linkage frame 306 connected to its upper surface. After the feed hopper 4 is in position, the embedded ring 401 at one end is inserted into the inner wall of the feed inlet of the concrete mixer 101, ensuring that the raw materials smoothly enter the mixer. Then, through the microwave moisture sensor 7 in the snap-fit ​​block 5 within the hollow hole on the upper surface of the middle section of the feed hopper 4, after the raw materials are fed, the slider 305 drives the feed hopper 4 to move and leave a space between it and the concrete mixer 101. The microwave moisture sensor 7 then detects the moisture content of the concrete raw materials in real time and transmits the data wirelessly to the controller 203. After receiving the moisture data from the microwave moisture sensor 7, the controller 203 performs analysis according to a preset program and algorithm. When the detected moisture content does not meet the requirements for concrete mixing, the controller 203 and the water pump 204 are connected via a signal. When moisture adjustment is needed, the controller 203 sends a command to the water pump 204. The input end of the water pump 204 is connected to the water tank 205 located at the lower end of the support frame 1 through the water inlet pipe 206. After the water pump 204 starts, it draws water from the water tank 205. The water enters the water outlet pipe 210 through the output end of the water pump 204, and then passes through the nozzle at one end of the water outlet pipe 210. 211 is set up in correspondence with concrete mixer 101 to spray water into concrete mixer 101 to achieve control of concrete mixing moisture. When feeding, the water outlet pipe 210 can be moved to one end to prevent it from affecting the engagement of the embedded ring 401. After feeding is completed, the feed hopper 4 moves backward to engage the water outlet pipe 210 in the limiting block 209. The starting screw 304 drives the feed hopper 4 to move, so that the limiting groove 402 at one end of the embedded ring 401 and the limiting block 209 work together to fix the water outlet pipe 210.

[0040] The overall structure of this utility model embodiment can improve the accuracy of moisture control during concrete mixing, and can reduce errors and the need to rely on traditional manual experience and timed sampling methods, thereby reducing the fatigue and efficiency impact caused by manual water addition.
