Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a water-brushed stone slurry quantity-controlled anti-condensation construction control system and a control method. Background Art

[0002] With the acceleration of urbanization, the demand for the protection and restoration of historical buildings is growing. In the restoration and protection of traditional historical buildings, especially the restoration of water-brushed stone veneers, there are many challenges. Existing technical solutions often lack attention to precise batching and post-construction quality inspection, resulting in a large difference between the restoration effect and the original building style. In addition, the preparation and inspection process of the sample is time-consuming and inefficient, the proportion data is not accurately recorded, there is a lack of effective machine learning algorithms to optimize the batching scheme, and the quantity control and anti-condensation measures of the water-brushed stone slurry are insufficient. These problems have seriously affected the construction quality and efficiency, and thus affected the progress and cost of the entire project.

[0003] Specifically, the existing technology has the following limitations in the field of restoration of water-brushed stone veneer of historical buildings:

[0004] 1. The traditional method of repairing water-brushed stone finishes often relies on the experience and intuition of construction workers to manually weigh the proportions of cement, stone and pigment when mixing ingredients. This operation method that relies on personal feelings lacks consistency and repeatability, and leads to insufficient precision in the proportion of raw materials. The quality inspection after construction is difficult to meet the expected standards, which affects the coordination of the appearance of the restored building and the historical style, resulting in differences in texture and durability between the restored wall and the original wall. For example, construction workers may add too much water based on their feelings, resulting in increased fluidity of the stone slurry, but this also makes the stone slurry prone to cracks and fall off after drying on the wall; other examples include incorrect color matching of cement walls, resulting in differences in warm and cold colors, making it impossible to achieve perfect repair and restoration.

[0005] 2. In traditional repair work, the recording of the proportion data of the ingredients often relies on manual records, lacking systematic and digital management, recording and analysis. Especially for the same construction object, if a repair project is completed by different workers at different times, each worker may adjust the proportion according to his own experience, resulting in differences in the final repair effect. This lack of standardization and data-driven methods limits the predictability and controllability of the repair work, and often lacks the proportion information of the past repair due to data loss, which leads to differences in the proportion information of the water-brushed stone slurry used in the second repair construction. In addition, due to the characteristics of the water-brushed stone slurry, it is necessary to apply it to the wall and wait until it dries before verifying the effect of the proportion. If a sample is used, it will take time and raw material costs; at the same time, since the water-brushed stone slurry has high requirements for the precision of the raw material proportion, the water-brushed stone slurry that is mixed and mixed by relying solely on the experience of the construction personnel in the existing technology is prone to errors in the color proportion after mixing. If the error is found after the wall is solidified and washed, it is not only necessary to knock it out and re-construct, which reduces the construction efficiency, but also difficult to determine the proportion adjustment direction and specific dosage calculation by naked eye.

[0006] 3. In the current construction process, the amount of water-brushed stone slurry is not accurately controlled, which will lead to waste of raw materials and construction quality problems; and, due to the complexity of water-brushed stone construction, if the anti-condensation measures are insufficient, the water-brushed stone slurry will easily dry and condense during the construction process, causing waste of raw materials, affecting the continuity of the construction progress and the quality of repair, and may even cause damage to the mixer, further increasing the construction cost. In addition, due to the complex proportion of water-brushed stone itself, the cost of separating and recycling the raw materials of discarded water-brushed stone is higher than that of concrete with a single component. Therefore, after solidification, it is often discarded. Traditional concrete can be reused after reprocessing even if it solidifies due to untimely construction. Therefore, how to ensure that the water-brushed stone slurry used in each construction can meet the needs of a single construction under the premise of stable proportion quality is of great significance. In the past, in the production process of water-brushed stone slurry for construction finishes, it needed to be used up in about an hour after normal mixing. Although it could be done in small quantities multiple times traditionally, it was difficult to ensure the stable quality of each batch, and each calculation of the amount and viscosity required estimation and observation by experienced construction personnel, which increased the burden on construction personnel and reduced construction efficiency. At the same time, each batch of water-brushed stone slurry could not guarantee the stability of the mix ratio and quality, which had an impact on subsequent wall flushing and other aspects.

[0007] Therefore, in order to better protect and inherit the unique style and cultural value of historical buildings, it is urgent to provide a more efficient, accurate and reliable water-brushed stone veneer restoration solution to significantly improve the quality and efficiency of restoration work. Summary of the invention

[0008] In order to solve the problems existing in the prior art mentioned above, the purpose of the present invention is to provide a water-brushed stone slurry controlled quantity anti-condensation construction control system and control method, which adopts visual recognition and data processing technology to achieve precise batching and quality inspection, and improve construction efficiency and quality; through intelligent switching of different working modes, it adapts to construction needs, reduces raw material waste, and ensures construction continuity and quality stability; and through automatic cleaning and raw material ratio memory functions, it reduces labor costs and quickly restores the construction status. It is especially suitable for water-brushed stone slurry construction with complex proportions and high precision requirements, and effectively protects the historical architectural style.

[0009] In order to achieve the above-mentioned purpose and other related purposes, the present invention adopts the following technical solutions:

[0010] In a first aspect of the present invention, a water-brushed stone slurry quantity control and anti-condensation construction control system is provided, comprising a mixer body, wherein the mixer body comprises a silo, a mixing area and a slurry outlet, and further comprises a control unit, a visual recognition unit, a data collection unit and a data processing and storage unit, wherein:

[0011] There are several silos, each of which is provided with a discharge valve, a discharge channel and a weighing sensor. The discharge valve is arranged at the bottom of the silo, and the discharge valve is connected to the mixing area through the discharge channel. The discharge valve and the weighing sensor are connected to the control unit by electrical signals for determining and controlling the quantitative feeding of raw materials.

[0012] The mixing zone is provided with a servo motor, a slurry discharge valve, a slurry discharge channel and a displacement sensor; the slurry discharge valve is arranged at the bottom of the mixing zone, and the slurry discharge valve is communicated with the slurry discharge port through the slurry discharge channel, and a displacement sensor is arranged in the slurry discharge channel, and the displacement sensor is used to monitor and record the actual slurry discharge volume and single emptying volume of the water-brushed stone slurry; the servo motor is connected to the control unit by electrical signals, and the start and stop and operation interval are controlled by the control unit, and the discharge valve and the slurry discharge valve are also connected to the control unit by electrical signals, and are controlled to open and close by the control unit;

[0013] The control unit includes a PLC controller, which is used to control the opening and closing of the discharge valve, the slurry discharge valve, the operating state of the servo motor in the mixing area, and is also used to control the switching of different working modes of the mixer body; the PLC controller is electrically connected to the visual recognition unit, the data collection unit, and the data processing and storage unit respectively; the visual recognition unit is used to collect visual data of water-brushed stone and cement in real objects or photos, and transmit it to the data collection unit through the control unit; the data collection unit is used to collect visual data, construction information data, real-time data of weighing sensors and displacement sensors, and transmit it to the data processing and storage unit through the control unit for processing Data processing; the data processing storage unit is used to analyze the data collected by the data collection unit, and obtain the raw material ratio of the water-brushed stone slurry based on the collected visual data. The raw material ratio includes stone type, stone particle size, stone ratio, mud-stone ratio, cement color pigment ratio. At the same time, based on the mud-stone ratio in the raw material ratio, the solidification time of the unit weight of the water-brushed stone slurry under the current raw material ratio is analyzed, and combined with the entered construction information data, the total daily amount and the batch amount for a single mixing are calculated, and the results of the data analysis are fed back to the control unit to control the mixer body to batch, stir and discharge the slurry, and the results of the data analysis are stored and recorded.

[0014] As a preferred technical solution, the outlet of the discharge channel extends into the mixing zone, so that the raw materials fall into the mixing zone through the outlet of the discharge channel, and the discharge channel adopts a closed channel.

[0015] As a preferred technical solution, the raw materials include dry materials and water, and the sensor includes a weight sensor for weighing the dry materials and a flow sensor for weighing water.

[0016] A second aspect of the present invention provides a method for controlling the amount of water-brushed stone slurry and anti-condensation construction, comprising the following steps:

[0017] S1. Obtain the raw material ratio of water-brushed stone slurry through visual data collection and intelligent recognition, wherein the raw material ratio includes stone type, stone particle size, stone ratio, mud-stone ratio, and cement color pigment ratio; and determine the setting time of unit weight of water-brushed stone slurry under the current raw material ratio according to the mud-stone ratio in the raw material ratio;

[0018] S2. Enter the construction information, and obtain the total amount for the day based on the raw material ratio. At the same time, obtain the batch amount for a single mixing according to the setting time of the unit weight of the water-brushed stone slurry and the preset average construction area per person per hour;

[0019] S3. According to the batch dosage and the preset material discharge sequence, the precise batching is controlled and the water-brushed stone slurry is automatically stirred and mixed in batches;

[0020] S4, after all the raw materials in step S3 are discharged, continue to stir and monitor the viscosity of the water-brushed stone slurry until it meets the requirements and then discharge the slurry. When discharging the slurry, the actual discharge amount of the water-brushed stone slurry is recorded in real time through the displacement sensor;

[0021] S5. After a single slurry discharge is completed, steps S3 and S4 are repeated until the accumulated actual slurry discharge volume reaches the total daily volume and then the program is switched to the automatic cleaning program.

[0022] As a preferred technical solution, the control system can adapt to different construction requirements and conditions by switching working modes, and the working modes include continuous operation mode, short stop mode, long stop mode or stop mode:

[0023] When the mixer body is started for the first time, it automatically switches to the continuous operation mode, the slurry outlet valve is closed, and the servo motor maintains the continuous stirring state until the viscosity of the water-brushed stone slurry meets the requirements and automatically switches to the short stop mode;

[0024] When switched to the short stop mode, the opening and closing of the slurry discharge valve is manually controlled, and the servo motor switches from the continuous stirring state to the interval stirring state. When discharging slurry, the displacement sensor cumulatively records the actual slurry discharge amount of the water-brushed stone slurry. After a single slurry discharge is completed, steps S3 and S4 are repeated until the actual slurry discharge amount reaches the total daily amount, and then the automatic cleaning procedure is performed;

[0025] When switched to the long stop mode, the slurry discharge valve is opened, and the servo motor maintains continuous stirring until the water-brushing stone slurry in the mixing area is emptied, then the slurry discharge valve is closed, and the displacement sensor records the emptied amount of the water-brushing stone slurry during the emptied state; the emptied amount is included in the remaining amount of the day, and the remaining amount of the day = the total amount of the day - the actual slurry discharge amount + the emptied amount. When switching back from the long stop mode to the short stop mode, steps S3 and S4 are repeated until the remaining amount of the day is completed, and then the automatic cleaning procedure is performed;

[0026] When switched to the stop mode, the slurry outlet valve opens and the servo motor maintains continuous stirring until the water-brushed stone slurry in the mixing area is drained, then the slurry outlet valve is paused and closed, and an automatic cleaning procedure is performed at the same time.

[0027] Furthermore, when the automatic cleaning program is performed, the current raw material ratio is automatically recorded and memorized, and when the mixer body is started again, the raw material ratio is automatically read and the construction information of the day is prompted to be input.

[0028] Furthermore, when the construction project is different, by performing the operation of step S1, after completing step S1 to obtain a new raw material ratio, the new raw material ratio information automatically overwrites the original raw material ratio, and the solidification time is recalculated and determined.

[0029] As a preferred technical solution, in step S2, the construction information includes the number of construction workers and the construction duration for the day. Combined with the preset average construction area per person per hour, the construction area for the day is automatically calculated and converted to the total amount for the day in combination with the raw material ratio.

[0030] As a preferred technical solution, in step S4, the viscosity of the water-brushed stone slurry is monitored in real time through the rotational torque feedback of the servo motor.

[0031] As a further preferred technical solution, in step S4, the time it takes for the ripples on the surface of the water-brushed stone slurry to calm down is also monitored by a visual module to assist in determining the viscosity of the water-brushed stone slurry in the current stirring state.

[0032] As described above, the present invention has the following beneficial effects:

[0033] (1) The water-brushed stone slurry quantity control and anti-condensation construction control system and control method of the present invention utilize advanced visual data acquisition and intelligent recognition technology to obtain a more accurate water-brushed stone slurry raw material ratio, avoid errors caused by human experience, and reduce trial and error costs. At the same time, since it relies on the data processing system for automatic calculation, there is no need for ratio identification and calculation experience for the construction finish, which saves training costs and improves construction efficiency and quality. It can achieve accurate batching and ensure that the quality inspection after construction can meet higher standards, thereby better restoring and protecting the original appearance of historical buildings. In addition, through clear construction finish boundary lines, it is possible to obtain a more accurate construction area of ​​the construction finish through visual data acquisition and analysis, and then more accurately calculate the required raw material quantity, optimize construction planning and resource allocation, improve construction efficiency and quality control, and ensure the aesthetics and consistency of construction results. In addition, accurate area measurement also helps to reduce raw material waste, reduce construction costs, and provide important reference data for subsequent maintenance and restoration work.

[0034] (2) The present invention provides a water-brushed stone slurry quantity-controlled anti-setting construction control system and control method. Through this intelligent construction control system, combined with the raw material ratio of the water-brushed stone slurry and the input construction information, it can ensure the effective grasp of the setting time of the water-brushed stone slurry per unit weight, and on this basis, realize the on-demand production of batch quantities. At the same time, through uninterrupted batch production and visual recognition and the rotational torque feedback data of the servo motor, real-time monitoring of the viscosity of the water-brushed stone slurry during the mixing process is realized, thereby ensuring the continuity of the construction process and the quality stability of each batch of water-brushed stone slurry, and ultimately achieving the purpose of improving construction efficiency and quality.

[0035] (3) The water-brushed stone slurry quantity control and anti-condensation construction control system and control method of the present invention can adapt to different construction conditions and requirements through flexible switching of four working modes, improve construction efficiency, reduce raw material waste, ensure construction quality, and also reduce the workload of operators. Specifically, in the continuous operation mode, the uniformity and quality of the water-brushed stone slurry can be ensured by monitoring the viscosity during the continuous mixing process, avoiding the waste of raw materials or construction quality problems caused by insufficient mixing; in the short-stop mode, construction personnel are allowed to manually control the single slurry output according to the actual construction progress, and reduce unnecessary mixing through intermittent mixing. While preventing solidification or segregation, it also ensures that the stone does not sink to the bottom and the uniformity. At the same time, the actual slurry output is recorded by the displacement sensor, which helps to accurately control the use of raw materials; in the long-stop mode, it can ensure that the water-brushed stone slurry will not stay in the mixer for a long time and solidify. At the same time, the emptying volume is recorded by the displacement sensor to accurately calculate the remaining amount of the day, providing data support for subsequent construction or raw material preparation; in the stop mode, by completely emptying the water-brushed stone slurry in the mixer, the raw materials can be effectively prevented from solidifying and remaining in the equipment.

[0036] (4) The control system and control method for controlling the amount of water-brushed stone slurry and preventing coagulation of the present invention reduce the workload and time of manual cleaning through the automatic cleaning function, and can help to quickly restore the mixer to the previous construction state when it is restarted through the automatic memory recording of the raw material ratio. Especially for water-brushed stone slurry with complex raw material ratio and low error requirement, the automatic memory record extraction can improve the construction efficiency while ensuring the stable quality of the water-brushed stone slurry.

[0039] In order to better understand the purpose, structure and function of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] In the description of the present invention, it should be noted that the positional relationships indicated by terms such as “longitudinal”, “lateral”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside” and “outside” etc. cited in this specification are based on the positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Example 1

[0041] This embodiment provides a water-brushed stone slurry quantity control and anti-condensation construction control system, including a mixer body, a control unit, a visual recognition unit, a data collection unit and a data processing and storage unit, wherein:

[0042] like Figure 1 As shown, the mixer body includes a plurality of silos for storing raw materials, a mixing zone and a slurry outlet; the silos are detachably fixed on the mixer body, and each silo is provided with a discharge valve, a discharge channel and a weighing sensor, and the weighing sensor is electrically connected to the control unit for determining and controlling the quantitative feeding of the raw materials; the discharge valve is arranged at the bottom of the silo, and the discharge valve is connected to the mixing zone through the discharge channel, and further, the outlet of the discharge channel extends into the mixing zone, so that the raw materials fall into the mixing zone through the outlet of the discharge channel, and the discharge channel adopts a closed channel, which avoids dust pollution in the raw materials and reduces the weighing error caused by flying dust when feeding after weighing.

[0043] In this embodiment, the raw materials include dry materials and water, and the dry materials include various types of gravel, cement powder and cement color pigments. The weighing sensor includes a weight sensor and a flow sensor, which are used to weigh the dry materials and water respectively. The flow sensor adopts a flow meter, and the flow meter is arranged at the outlet end of the discharge valve of the silo filled with water. The weight sensor adopts a subtraction scale, and the subtraction scales are symmetrically arranged in pairs at the installation position between the silo filled with dry materials and the mixer body. Subtraction weighing can be used to make the ingredients more accurately, and the precise control of the amount of feeding can be fed back to the control unit in time to control the closing of the discharge valve, thereby improving the accuracy of the proportioning and avoiding waste.

[0044] The mixing zone is provided with a servo motor, a slurry discharge valve, a slurry discharge channel and a displacement sensor; the slurry discharge valve is arranged at the bottom of the mixing zone, and the slurry discharge valve is communicated with the slurry discharge port through the slurry discharge channel, a displacement sensor is arranged in the slurry discharge channel, and the displacement sensor is electrically connected to the control unit by signals, and is used to monitor and record the actual slurry discharge volume and single emptying volume of the water-brushed stone slurry; the servo motor is electrically connected to the control unit by signals, and is controlled by the control unit to start and stop and operate at intervals, the discharge valve and the slurry discharge valve are also electrically connected to the control unit by signals, and are controlled to open and close by the control unit, so that the mixer body has a switchable working mode during the mixing process, and the working mode includes four working modes: continuous operation mode, short stop mode, long stop mode and stop mode.

[0045] The control unit includes a PLC controller, which is used to control the opening and closing of the discharge valve, the slurry discharge valve, the operating state of the servo motor in the mixing area, and is also used to control the switching of different working modes of the mixer body; the PLC controller is electrically connected to the visual recognition unit, the data collection unit, and the data processing and storage unit respectively; the visual recognition unit is used to collect visual data of water-brushed stone and cement in real objects or photos, and transmit it to the data collection unit through the control unit; the data collection unit is used to collect visual data, construction information data, real-time data of weighing sensors and displacement sensors, and transmit it to the data processing and storage unit through the control unit for digital processing. The data processing and storage unit is used to analyze the data collected by the data collection unit, and obtain the raw material ratio of the water-brushed stone slurry according to the collected visual data, wherein the raw material ratio includes the type of stone, stone particle size, stone ratio, mud-stone ratio, cement color pigment ratio, and at the same time, according to the mud-stone ratio in the raw material ratio, the setting time of the unit weight of the water-brushed stone slurry under the current raw material ratio is analyzed and obtained, and the total daily amount and the batch amount for a single mixing are calculated in combination with the entered construction information data, and the above results after data analysis are fed back to the control unit to control the mixer body to batch, stir and discharge the slurry, and the results after data analysis are stored and recorded.

[0046] Since the setting time of cement mortar is mainly affected by cement type, water-cement ratio, ambient temperature and humidity, additives, etc., the approximate initial setting time and final setting time under a specific water-cement ratio and formula can be obtained through experimental testing under laboratory conditions, and the corresponding empirical formula can be obtained; in actual use, the initial setting time of cement mortar can be determined by inputting a specific ratio and accurately quantifying and standardizing the mixing by mechanical equipment such as a mixer. In short, the setting time of cement mortar per unit weight is input into the controller after the data is obtained in the preliminary experiment, and the initial setting time can be calculated by looking up the table when it is needed in the subsequent use process. In this embodiment, since the addition of stones does not affect the setting time of cement mortar itself under unit weight, the actual proportion of cement mortar can be obtained according to the ratio of mud and stone in the raw material ratio, and the water-cement ratio can be obtained from the cement dosage and water dosage in the raw material ratio, and then according to the setting time data of cement mortar per unit weight at the current water-cement ratio, the setting time of water-brushed stone mortar per unit weight under the current raw material ratio is calculated and analyzed. Example 2

[0047] like Figure 2 As shown, this embodiment provides a method for controlling the amount of water-brushed stone slurry to prevent condensation, which utilizes the control system in Example 1. The method includes:

[0048] S0. Clean the construction surface to ensure that the boundary line of the construction surface is clear, which is conducive to improving the accuracy of visual data collection and avoiding errors caused by manual measurement.

[0049] S1. Obtain the raw material ratio of water-brushed stone slurry by performing visual data collection and intelligent recognition on the construction finish or construction reference photos. The raw material ratio includes stone type, stone particle size, stone ratio, mud-stone ratio, cement color pigment ratio. At the same time, determine the solidification time of unit weight of water-brushed stone slurry under the current raw material ratio based on the mud-stone ratio in the raw material ratio.

[0050] In this embodiment, when the original reference surface is retained on the construction surface, the raw material ratio is obtained by scanning and identifying the construction surface, ensuring that the repaired wall surface is the same as the original wall surface, thereby maintaining the consistency and aesthetics of the building.

[0051] In other embodiments, when there is no original reference surface on the construction finish, the raw material ratio is obtained by scanning and identifying the construction reference photo.

[0052] S2. Manually enter construction information, which includes the number of construction workers and the construction duration of the day. Combined with the preset average construction area per person per hour, the construction area of ​​the day is automatically calculated, and combined with the raw material ratio, it is automatically converted to the total amount of the day. At the same time, based on the solidification time of the unit weight of water-brushed stone slurry, the batch amount for a single mixing is automatically calculated.

[0053] S3. According to the batch dosage and the preset discharge sequence, the precise batching is controlled and the mixing is automatically carried out in batches. Specifically, the control unit controls the silo where each raw material is located to automatically open the discharge port to discharge the material, and at the same time controls the order, interval and mixing time of each raw material being put in. The precise batching is achieved by setting a weighing sensor at the discharge port of each raw material silo to monitor the dosage of each raw material in the batch dosage.

[0054] S4. When all the raw materials in batches in step S3 are added, continue to stir and monitor the viscosity of the water-brushed stone slurry until the viscosity of the water-brushed stone slurry meets the requirements and then the slurry is discharged from the slurry discharge channel for standby use. The actual discharge amount of the water-brushed stone slurry is measured and accumulated and recorded in real time by a flow sensor arranged in the slurry discharge channel; wherein, the viscosity of the water-brushed stone slurry is monitored in real time through the rotational torque feedback data of the servo motor, and the surface ripple calming time of the water-brushed stone slurry is assisted by the visual module to monitor the surface ripple calming time of the water-brushed stone slurry, so as to judge the viscosity of the water-brushed stone slurry in the current stirring state. When the rotational torque feedback data and the surface ripple calming time fall within the range of previous experimental data, it is determined that the viscosity of the water-brushed stone slurry has met the requirements.

[0055] S5, after a single slurry discharge is completed, steps S3 and S4 are repeated until the accumulated actual slurry discharge amount reaches the total daily amount and then the automatic cleaning program is switched. In this embodiment, the water used in the automatic cleaning program comes from a silo filled with water.

[0056] During the mixing process, the control system can adapt to different construction requirements and conditions by switching working modes, including continuous operation mode, short stop mode, long stop mode or stop mode:

[0057] When the mixer body is started for the first time, it automatically switches to the continuous operation mode, the slurry outlet valve is closed, and the water-brushed stone slurry is batched and mixed normally. The servo motor maintains a continuous stirring state until the viscosity of the water-brushed stone slurry meets the requirements and then automatically switches to the short stop mode.

[0058] When switched to the short-stop mode, the opening and closing of the slurry discharge valve is switched to manual control, and the control unit controls the servo motor in the mixing area to switch from the continuous stirring state to the interval stirring state. When discharging slurry, the displacement sensor cumulatively records the actual slurry discharge amount of the water-brushed stone slurry. After a single slurry discharge is completed, steps S3 and S4 are repeated until the actual slurry discharge amount reaches the total daily amount, and then the automatic cleaning procedure is performed; through the interval stirring in the short-stop mode, it can prevent solidification and ensure that the stone does not sink to the bottom, while also avoiding segregation caused by too long mixing time. In addition, the controllability of the single slurry discharge amount can effectively adapt to different construction containers and is not limited by the size of the construction site, so that more precise repair operations can be performed;

[0059] When switched to the long stop mode, the slurry discharge valve is opened, and the control unit controls the servo motor in the mixing area to maintain continuous stirring until the servo motor is paused and the slurry discharge valve is closed after the water-brushing stone slurry in the mixing area is emptied. During the emptying, the displacement sensor records the emptying amount of the water-brushing stone slurry. At this time, the emptying amount of the water-brushing stone slurry discharged through the slurry discharge channel is included in the remaining amount of the day, and the remaining amount of the day = the total amount of the day - the actual slurry discharge amount + the emptying amount. When switching from the long stop mode to the short stop mode again, step S3 and step S4 are performed until the remaining unfinished part of the total amount of the day is completed, that is, when the remaining amount of the day is completed, the automatic cleaning procedure is performed;

[0060] When switched to the stop mode, the slurry outlet valve opens, and the control unit controls the servo motor in the mixing area to maintain continuous stirring until the water-brushed stone slurry in the mixing area is emptied, then the slurry outlet valve is closed and an automatic cleaning procedure is performed;

[0061] When the automatic cleaning procedure is performed, the current raw material ratio is automatically recorded and memorized. When the mixer body is started again, the raw material ratio is automatically read and the construction information of the day is prompted to be entered;

[0062] When the construction projects are different, by performing the operation of step S1, after completing step S1 to obtain a new raw material ratio, the new raw material ratio information automatically covers the original raw material ratio, and the solidification time is recalculated to ensure the consistent stability of the water-brushed stone slurry mixed in the same construction project, and ensure the independence between different projects.

[0063] The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention. It is known to those skilled in the art that various changes or equivalent replacements may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and raw materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application belong to the scope protected by the present invention.
