[0033] In this embodiment, the loading assembly 101 transports the raw materials to the subsequent processing link. The first moving wheel 104 is installed at the bottom of the loading device 105, so that the entire loading assembly 101 can be easily moved. The loading device 105 is used to load solid materials or part of the premix. The liquid tank 106 stores the liquid components used for grouting, such as water or other liquid additives.

[0034] The grouting assembly 102 is mainly responsible for proportioning, storing and conveying slurry. The batching box 107 is used to mix solid materials and liquids in proportion. The connector matches the outlet on the feeder 105 to facilitate material transmission. The liquid inlet head is connected to the liquid tank 106 to add the required liquid components. The slurry storage barrel 108 is connected to the batching box 107 and is used to store the mixed slurry. The grouting pump 109 is connected to the slurry storage barrel 108 through a pipeline and is used to pump the slurry to the grouting site.

The solid-liquid mixing is completed inside the batching box 107 to form a uniform slurry. The mixed slurry is transported to the slurry storage barrel 108 for temporary storage. As needed, the slurry in the slurry storage barrel 108 is pumped to the designated grouting point by the grouting pump 109. During the whole process, the control component 103 continuously monitors the amount of slurry in the slurry storage barrel 108, and automatically starts the batching box 107 for replenishment when necessary.

[0037] Thus, the automatic batching and grouting process is realized through the control component 103, reducing the need for manual intervention. Through the design of the moving wheel, the system can be flexibly moved in the underground environment to adapt to different working surface requirements.

[0038] The feeder 105 includes a feeding box 112, a feeding screw 113, a discharging barrel 114 and a driving motor 115. The feeding screw 113 is tiltedly arranged in the feeding box 112, the output end of the driving motor 115 is fixedly connected to the feeding screw 113, and the discharging barrel 114 is arranged on one side of the feeding screw 113.

[0039] The loading box 112 is used to accommodate the solid raw materials to be processed. The loading screw 113 is installed obliquely in the loading box 112, and is used to push the raw materials from the bottom of the box upward to the discharge barrel 114. The discharge barrel 114 is arranged on one side of the loading screw 113, and is used to guide the raw materials into the batching box 107. The output end of the driving motor 115 is fixedly connected to the loading screw 113 to provide power for the loading screw 113.

[0040] The feeder 105 further includes a bag breaking blade 116 , and the bag breaking blade 116 is disposed at the bottom of the feeding screw 113 .

[0041] The bag breaking blade 116 is disposed at the bottom of the feeding screw 113 and is used for cutting the raw material packaging bag so that the raw material can flow smoothly into the feeding box 112 .

[0042] The feeding assembly 101 further includes a limiting plate 117 , which is disposed on the top of the bag breaking blade 116 and fixed in the feeding box 112 .

[0043] The limiting plate 117 is installed above the bag breaking blade 116 and fixed inside the feeding box 112, which plays a role in limiting the flow speed of the raw materials and preventing excessive accumulation of the raw materials.

The drain valve 123 is arranged at the bottom of the filter box 121 and is connected to the discharge barrel 114.

[0046] The cover plate 118 is rotatably connected to the feeding box 112 and is located on one side of the feeding box 112, and is used to close the feeding box 112 and control dust emission. The fan 120 of the dust collector 119 is installed on the cover plate 118, and is used to generate negative pressure suction to collect dust generated during the feeding process. The air inlet pipe of the filter box 121 is connected to the fan 120, and is used to filter dust particles in the air. The exhaust pipe 122 is installed on the top of the filter box 121, and is used to discharge the clean air after filtration. The drain valve 123 is installed at the bottom of the filter box 121 to discharge the liquid that absorbs cement ash during the filtration process. In order to improve the utilization efficiency of raw materials, the liquid that absorbs cement ash can also be introduced into the material box.

[0047] The dust collector 119 further includes a first agitator 124 , which is disposed in the filter box 121 .

[0048] The first agitator 124 is installed inside the filter box 121, and is used to agitate and mix the liquid and dust collected in the filter box 121, so as to achieve a better absorption effect.

[0049] The batching box 107 includes a box body 125, a gravity sensor 126, a stirring motor 127, a first stirring rod 128 and a mud pump 129. The gravity sensor 126 is arranged at the bottom of the box body 125, the stirring motor 127 is fixed at the top of the box body 125, the first stirring rod 128 is fixedly connected to the output end of the stirring motor 127 and is located in the box body 125, and the mud pump 129 is connected to the box body 125 and connected to the slurry storage barrel 108.

[0050] The box 125 is used as a main container for mixing solid raw materials and liquids. A gravity sensor 126 is installed at the bottom of the box 125 to detect the weight of the material in the box 125, so as to achieve accurate batching. The stirring motor 127 is fixed on the top of the box 125 to provide power for the stirring process. The first stirring rod 128 is fixedly connected to the output end of the stirring motor 127, located in the box 125, and is used to mix the raw materials. The mud pump 129 is connected to the box 125 and to the slurry storage barrel 108, and is used to pump the mixed slurry into the slurry storage barrel 108.

[0051] The slurry storage barrel 108 includes a barrel body 130, a driven wheel 131, a driving wheel 132, a transmission belt 133 and a second stirring rod 134. The barrel body 130 is arranged on one side of the box body 125. The second stirring rod 134 is rotatably arranged in the barrel body 130. The driving wheel 132 is connected to the output end of the stirring motor 127. The driven wheel 131 is fixed on the second stirring rod 134. The transmission belt 133 is connected to the driven wheel 131 and the driving wheel 132.

[0052] The barrel body 130 of the slurry storage barrel 108 is used as a container for storing the mixed slurry. The driven wheel 131 is installed on the second stirring rod 134 for transmitting power. The driving wheel 132 is connected to the output end of the stirring motor 127 for driving the second stirring rod 134. The transmission belt 133 connects the driving wheel 132 and the driven wheel 131 for transmitting power. The second stirring rod 134 is installed in the barrel body 130 for keeping the slurry uniform.

[0053] The control component 103 includes a liquid level detection unit 135, a residual amount calculation unit 136 and a control unit 137. The liquid level detection unit 135 is used to detect the liquid level height in the collection barrel 130. The residual amount calculation unit 136 is used to calculate the mud residual in the barrel 130 based on the liquid level height. The control unit 137 is used to control the box 125 to feed and stir the mixed mud again after the mud residual is lower than a preset value.

[0054] The liquid level detection sensor is installed in the slurry storage barrel 108 to monitor the liquid level of the slurry in the barrel in real time. The signal from the liquid level detection sensor is received and converted into a data format that can be understood by the control system.

[0055] The remaining amount calculation unit 136 receives the liquid level information provided by the liquid level detection unit 135 and calculates the actual remaining amount of the slurry in the barrel 130 based on the liquid level.

[0056] The control unit 137 receives data from the surplus calculation unit 136 and makes decisions according to a preset logic, such as controlling the operation of the batching box 107, such as starting the stirring motor 127, opening the feed valve, etc.

[0057] When the slurry level in the slurry storage barrel 108 changes, the sensor in the liquid level detection unit 135 will detect the change. The signal processor converts the liquid level signal collected by the sensor into a digital signal and transmits it to the remaining amount calculation unit 136. After receiving the liquid level signal, the remaining amount calculation unit 136 uses the capacity data of the barrel 130 in the memory and the current liquid level height to calculate the slurry remaining in the barrel 130. The calculation result will be compared with the preset threshold value. When it is lower than the threshold value, the batching box 107 can be controlled to mix and mix the ingredients to produce new slurry.

[0058] In this way, the control component 103 can effectively manage the entire grouting process, ensure the continuous supply of mud, and maintain the stable operation of the system. This not only improves production efficiency, but also reduces the need for manual intervention and enhances the reliability and safety of the entire system.

[0059] Second embodiment

[0060] See also Figure 6 The present invention also provides a method for using a mobile integrated automated grouting system in a coal mine, comprising:

[0061] S201: Move the grouting assembly 102 to the location where grouting is required in the well for connection;

[0062] First, the operator needs to ensure that the grouting system is in a safe state and all power sources are turned off.

[0063] Use appropriate transportation tools or equipment (such as mine cars, trailers, etc.) to transport the grouting assembly 102 to the designated working surface underground. After arriving at the destination, connect the grouting assembly 102 to the fixed facilities underground according to the requirements of the operation manual. This may include pipeline connection, power connection, etc.

[0064] Check whether all connections are firm and reliable to prevent leakage and other problems during the grouting process.

[0065] S202: Move the loading assembly 101 to the loading position via the first moving wheel 104, place the cement bag on the loading device 105, and add the mixed liquid into the liquid tank 106;

[0066] The operator starts the moving wheel on the loading assembly 101 and pushes it to the location where the cement bags are stored. The cement bags are placed on the loading device 105 manually or using a robotic arm to ensure that they are placed firmly to avoid falling during the movement. At the same time, the pre-prepared mixed liquid is added to the liquid tank 106 of the system. The composition and proportion of the mixed liquid should be determined according to actual needs and strictly implemented as required. After adding the mixed liquid, check the sealing of the liquid tank 106 to ensure that no leakage occurs during the subsequent mixing process.

[0067] S203 moves the feeding assembly 101 and docks it with the batching box 107;

[0068] Start the moving wheel again and move the loading assembly 101 loaded with cement bags to the side of the batching box 107. During docking, ensure that the interface between the loading assembly 101 and the batching box 107 is aligned and tightly connected to prevent the material from spilling or leaking during the transmission process.

[0069] S204: adding the cement in the feeder 105 and the mixed liquid in the liquid tank 106 into the batching tank 107 in proportion for stirring;

[0070] The required ratio of cement and mixed liquid is set in the batching box 107. The cement is automatically or manually poured into the batching box 107 through the feeder 105. An appropriate amount of mixed liquid is drawn from the liquid tank 106 and added to the batching box 107. The stirring device is turned on to fully mix the cement and the mixed liquid to form a uniform slurry.

[0071] S205 The mud after stirring enters the mud storage barrel 108 for storage;

[0072] When the mud reaches a predetermined consistency and uniformity, the stirring is stopped. The valve between the batching box 107 and the mud storage barrel 108 is opened to allow the mud to flow into the mud storage barrel 108 for storage. The mud storage barrel 108 should have good sealing performance to prevent the mud from deteriorating or overflowing.

[0073] S206 starts the grouting pump 109 to output the mud for grouting.

[0074] After completing the above steps, check whether the entire system has any abnormal conditions. If everything is normal, start the grouting pump 109 to transport the slurry in the slurry storage barrel 108 to the location where grouting is required through the pipeline. During the grouting process, the operator should closely monitor the pressure gauge and other indicators to ensure the safety and effectiveness of the grouting process.

[0075] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
