Technical Field
[0001] This utility model relates to the field of mixing device technology, specifically a dry mortar mixing control device. Background Technology
[0002] Dry-mixed mortar is a pre-mixed building material mainly composed of cement, sand, admixtures, and additives, widely used in masonry and plastering projects. Compared with traditional wet mortar, dry-mixed mortar has advantages such as convenient construction, stable quality, and saving time and materials. In building construction, the performance of dry-mixed mortar directly affects the quality of the project; therefore, the proportioning and uniform mixing of the raw materials are crucial.
[0003] Patent CN219027988U discloses a proportioning control device for dry-mixed mortar, relating to the technical field of proportioning control devices. It addresses the problem in existing technologies where the output of raw materials cannot be accurately controlled during raw material proportioning in dry-mixed mortar production, hindering the accurate mixing of different raw materials. The device comprises a material conveying pipe fixedly installed below the material box, a discharge box fixedly installed below the material conveying pipe, a conveying box below the discharge box, a discharge roller inside the discharge box, a discharge groove outside the discharge roller, symmetrically arranged mating blocks on both sides of the discharge roller, a mating groove on the side of the mating block closest to the discharge roller (the groove is arc-shaped), an inclined groove above the mating groove on one side of the mating block, a guide pipe below the discharge roller, and an encoder fixedly installed at the rear end of the discharge box, the encoder being fixedly connected to the roller shaft of the discharge roller.
[0004] While existing technologies can achieve precise proportions of different raw materials in dry-mixed mortar, the quantitative output using a discharge roller has significant limitations. For example, if the discharge roller outputs a fixed value (e.g., 500 grams) per revolution, it becomes difficult to accurately output 6310 grams of raw material. This method of quantitative output easily leads to inaccurate proportions in practical applications, thus affecting the overall performance of the dry-mixed mortar. Therefore, based on the shortcomings of existing technologies, we propose a dry-mixed mortar mixing control device to improve the accuracy of proportions and the uniformity of mixing, meeting the higher requirements of the modern construction industry for dry-mixed mortar production.

[0016] Please see Figures 1-4 This utility model provides a technical solution: A dry-mixed mortar mixing control device includes a conveying assembly 100 for premixing and conveying raw materials, such as...

The top of the bracket 210 is provided with two weighing sensors 220 arranged symmetrically front and back for real-time monitoring of the weight difference of the raw materials in the rectangular storage box 230. The rectangular storage box 230 is located directly above the bracket 210 for storing a single raw material.

The output end of the conical discharge bin 232 is provided with a discharge device 240 for controlling the output amount of the raw material. like Figure 4 As shown, the discharge component 240 includes a rectangular guide pipe 241 connected to the conical discharge bin 232, used to guide the raw materials into the premixing conveying pipe 110. The output end of the rectangular guide pipe 241 is connected to the premixing conveying pipe 110. The outer wall of the rectangular guide pipe 241 is provided with a weighing plate 242. The bottom of the weighing plate 242 abuts against the weighing sensor 220 and is used to transfer the weight to the weighing sensor 220. The right side of the rectangular guide pipe 241 is provided with a mounting plate 243 for fixing the electric telescopic rod 244.

The weighing sensor 220 and the electric telescopic rod 244 are used together. The external power supply and controller work together. The weighing sensor 220 is used to detect the weight difference before and after the output. When the detected weight difference is the required output ratio, the controller controls the movable rod of the electric telescopic rod 244 to extend, so that the baffle plate 245 closes the rectangular guide tube 241. like Figure 1 As shown, the output end of the premixed conveying pipe 110 is equipped with a mixing component 300 for final mixing of raw materials and discharge.
[0017] In this embodiment, as Figure 2 As shown, the premixed conveying pipe 110 is equipped with an auger 120 for conveying raw materials by a screw. The left end of the premixed conveying pipe 110 is equipped with a first motor 130 through the pipe cover for driving the auger 120 to rotate, providing the power source for the auger 120 and operating with an external power supply.
[0018] Specifically, in combination Figure 3 and Figure 4As shown, the top of the premixing conveying pipe 110 is provided with a plurality of first rectangular clearance openings 111, and the rectangular guide pipes 241 of the plurality of proportioning components 200 pass through the plurality of first rectangular clearance openings 111 respectively, so that the rectangular guide pipes 241 of the proportioning components 200 can pass through to connect to the premixing conveying pipe 110. The top of the bracket 210 has a second rectangular clearance opening 211 for the rectangular guide tube 241 to pass through, ensuring that the rectangular guide tube 241 is installed in an accurate position. The top of the bracket 210 and near the front and rear sides are provided with limiting uprights 212 to ensure that the rectangular storage box 230 can only move up and down.

The bottom of the weighing horizontal plate 242 and near the front and rear sides are provided with circular clearance holes b2421 for the limiting uprights 212 to pass through, to prevent the weighing horizontal plate 242 from shifting and affecting the accuracy of the weighing sensor 220.
[0019] Furthermore, such as Figure 2 As shown, the mixing assembly 300 includes a mixing tank 310 for containing and mixing raw materials. The right end of the premixing conveying pipe 110 passes through the outer wall of the mixing tank 310. A rotating rod 330 is rotatably connected to the top of the inner wall of the mixing tank 310 via a bearing. A second motor 320 is provided on the top of the mixing tank 310 for driving the rotating rod 330 to rotate. It is powered by an external power source to provide power to the rotating rod 330. The outer wall of the rotating rod 330 is provided with multiple stirring blades 340 for stirring the raw materials in the mixing tank 310 to make them evenly mixed. The bottom of the mixing tank 310 is equipped with a discharge pipe 350 for discharging the mixed mortar.

[0020] In this embodiment, the dry-mixed mortar mixing control device first replenishes raw materials into the rectangular storage bin 230 through the feeding pipe 231, and then starts the external power supply to enable the weighing sensor 220 and the controller to enter the working state. When a mixing ratio is required, the controller controls the electric telescopic rod 244 to retract according to the preset mixing ratio parameters, and the baffle plate 245 opens the raw material flow through the rectangular guide pipe 241. The raw material enters the premixing conveying pipe 110 from the conical discharge bin 232 through the rectangular guide pipe 241. The weighing sensor 220 detects the weight change of the rectangular storage bin 230 in real time. When the weight difference reaches the preset value, the controller drives the electric telescopic rod 244 to extend, and the baffle plate 245 opens the rectangular guide pipe 241 to open the raw material flow. 5. A closed rectangular guide pipe 241 is formed; simultaneously, the first motor 130 drives the auger 120 to rotate in the premixing conveying pipe 110, conveying the initially mixed raw materials to the mixing tank 310; the second motor 320 drives the rotating rod 330 and the stirring blade 340 to rotate, performing secondary mixing of the raw materials, and finally the mixed mortar is discharged through the discharge pipe 350; during the process, the limiting upright 212 passes through the circular clearance hole a2331 of the auxiliary horizontal plate 233 and the circular clearance hole b2421 of the weighing horizontal plate 242, ensuring that the rectangular storage tank 230 and the weighing horizontal plate 242 move only in the vertical direction, avoiding horizontal deviation from interfering with the detection accuracy of the weighing sensor 220.
