[0021] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] like Figures 1 to 3 As shown, the automatic suction grouting vehicle 100 of the embodiment of the present invention includes a chassis 1, a walking assembly 2, a suction assembly 3, a stirring assembly 4 and a grouting assembly 5. The chassis 1 is arranged on the walking assembly 2, and the walking assembly 2 is used to drive the chassis 1 to move. The suction assembly 3 is arranged on the chassis 1, and the suction assembly 3 includes a vacuum generator 301, a storage barrel 302 and a suction pipe 303. The vacuum generator 301 is connected to the storage barrel 302 and is used to extract the air in the storage barrel 302 to form a negative pressure in the storage barrel 302. The suction pipe 303 is arranged on the storage barrel 302 and is used to use the negative pressure in the storage barrel 302 to suck the dry powder slurry into the storage barrel 302. The stirring assembly 4 is arranged on the chassis 1 and is connected to the storage barrel 302. It is used to receive the dry powder slurry discharged from the storage barrel 302 and stir and mix it with water to form a slurry. The grouting assembly 5 is arranged on the chassis 1 and is connected to the stirring assembly 4, and is used to prepare qualified slurry by the stirring assembly 4 for grouting.

[0023] When the automatic suction grouting vehicle 100 of the embodiment of the present invention is in use, the chassis 1 is installed on the walking component 2, and the automatic suction grouting vehicle 100 can be flexibly moved on site in the coal industry by driving the walking component 2. The vacuum generator 301 is started and connected to the storage barrel 302 to extract the air in the storage barrel 302 to form a negative pressure. The dry powder slurry is sucked into the storage barrel 302 by the negative pressure through the suction pipe 303. The dry powder slurry in the storage barrel 302 is stirred and mixed with water by the stirring component 4. The stirring component 4 ensures that the ratio of dry powder to water is uniform to form a slurry suitable for grouting. The prepared slurry is grouted through the grouting component 5. The grouting component 5 ensures the uniform injection of the slurry to achieve the purpose of reinforcement.

[0024] The automatic suction grouting vehicle 100 of the embodiment of the present invention greatly reduces the workload of manual handling, feeding and mixing by automatically sucking, mixing and grouting. The high degree of automation reduces the time of manual operation and improves the efficiency and continuity of grouting operations. The machine automatically controls the water-cement ratio to avoid the instability of the water-cement ratio during manual feeding, ensuring that the performance of the grouting material can be fully utilized. By accurately controlling the proportion and uniformity of the slurry, the grouting reinforcement effect is more reliable, which helps to improve the safety production level of the coal industry. Due to the reduction of manual operation, the dust and noise pollution on site are reduced, and the working environment is improved.

[0025] In some embodiments, the suction assembly 3 further includes a filter cartridge 304, through which the vacuum generator 301 is connected to the storage barrel 302, and the filter cartridge 304 is used to filter the dry powder slurry. The filter cartridge 304 is located between the vacuum generator 301 and the storage barrel 302. During operation, the filter cartridge 304 will filter the dry powder slurry to prevent it from being sucked into the vacuum generator 301.

[0026] In some embodiments, the filter cartridge 304 includes a cartridge body, a plurality of filter elements, and a valve. The plurality of filter elements are arranged in the cartridge body at intervals along the axial direction of the cartridge body, and the valve is arranged at the bottom of the cartridge body to open the cartridge body.

[0027] Multiple filter elements can achieve multi-stage filtration, which is beneficial to improving the working reliability of the filter cartridge 304. In addition, after the filter cartridge 304 has worked for a certain period of time, the dry powder slurry filtered in the cartridge is cleared by opening the valve to ensure the filtering effect of the filter cartridge 304.

[0028] In some embodiments, a first air pipe 305 is provided between the top of the cylinder and the vacuum generator 301 , a second air pipe 306 is provided between the bottom of the cylinder and the top of the material storage barrel 302 , and the first air pipe 305 is arranged away from the suction pipe 303 .

[0029] The first air pipe 305 is connected between the top of the filter cartridge 304 and the vacuum generator 301, and is used to transmit the negative pressure generated by the vacuum generator 301, so as to suck the dry powder slurry into the filter cartridge 304. The second air pipe 306 is connected between the bottom of the filter cartridge 304 and the top of the storage barrel 302, and is used to suck the filtered dry powder slurry. The first air pipe 305 is set away from the suction pipe 303, so that interference between the suction pipe 303 and the first air pipe 305 can be avoided, ensuring the smooth progress of the suction process.

[0030] In some embodiments, the suction assembly 3 also includes a reversing valve 307, which is disposed between the first air pipe 305 and the vacuum generator 301. When the weight of the dry powder slurry in the storage barrel 302 exceeds a preset value, the reversing valve 307 is reversed to allow the vacuum generator 301 to blow air into the storage barrel 302.

[0031] When the weight of the dry powder slurry in the storage barrel 302 reaches a preset value, the weight detection device sends a signal. The reversing valve 307 is reversed according to the signal of the weight detection device, so that the airflow direction generated by the vacuum generator 301 is reversed and air is blown into the storage barrel 302. The air blown in by the vacuum generator 301 can help loosen the dry powder slurry in the storage barrel 302, prevent the slurry from agglomerating, and ensure the uniform distribution of the slurry in the storage barrel 302. When the weight of the slurry in the storage barrel 302 is lower than the preset value, the reversing valve 307 is reversed again to resume the material suction state.

[0032] The combination of the reversing valve 307 and the weight detection device enables the weight of the dry powder slurry in the storage barrel 302 to be automatically controlled to avoid overloading. By automatically controlling the weight of the slurry, the safety risks that may be caused by overloading the storage barrel 302 are reduced. Blowing air into the storage barrel 302 can prevent the slurry from agglomerating and maintain good fluidity and uniformity of the slurry. Automatic reversing reduces the frequency of manual intervention and improves the work efficiency of the grouting operation.

[0033] In some embodiments, the automatic suction grouting vehicle 100 of the embodiment of the present invention further includes a plurality of support ears 6 and a plurality of support columns 7, and the plurality of support ears 6 correspond to the plurality of support columns 7 one by one. The plurality of support ears 6 are arranged at intervals along the circumference of the storage barrel 302, and the support ears 6 are downwardly stopped on the top surface of the support column 7, and the bottom of the storage barrel 302 is spaced from the chassis 1. A pressure sensor 8 is provided between the support ears 6 and the support column 7, and the pressure sensor 8 is used to detect the weight of the dry powder slurry in the storage barrel 302.

[0034] When the weight of the dry powder slurry in the storage barrel 302 changes, the pressure on the support ear 6 will also change accordingly. The pressure sensor 8 converts the detected pressure value into an electrical signal and transmits it to the control system. The control system calculates the weight of the slurry in the storage barrel 302 based on the signal of the pressure sensor 8 and compares it with the preset value. If the weight of the slurry in the storage barrel 302 exceeds the preset value, the control system will instruct the reversing valve 307 to reverse, and the vacuum generator 301 will start to blow air into the storage barrel 302 to reduce the weight of the storage barrel 302. When the weight of the slurry in the storage barrel 302 is lower than the preset value, the control system instructs the reversing valve 307 to resume the suction state.

[0035] The use of the pressure sensor 8 provides accurate weight detection, which helps to ensure the accuracy and efficiency of the grouting operation. The design of the support mechanism and the pressure sensor 8 allows the storage barrel 302 to remain stable during transportation and grouting, thereby improving safety performance. The entire weight detection and reversing control process has a high degree of automation, which reduces manual intervention and improves operating efficiency. By monitoring the weight of the storage barrel 302 in real time, the operator can understand the state of the slurry in a timely manner, which facilitates the adjustment and optimization of the grouting parameters. The risk of equipment damage caused by excessive weight of the slurry in the storage barrel 302 is avoided, thereby extending the service life of the equipment.

[0036] In some embodiments, a discharge port is provided at the bottom of the storage barrel 302, and a discharge valve 9 is provided on the discharge port. The automatic suction grouting vehicle 100 of the embodiment of the present invention further includes a screw feeder 10, and the stirring assembly 4 includes a stirring barrel 401. The feed port of the screw feeder 10 is connected to the discharge port of the storage barrel 302, and the discharge port of the screw feeder 10 is connected to the stirring barrel 401.

[0037] When the dry powder slurry in the storage barrel 302 reaches a certain amount, the control system will instruct the discharge valve 9 to open. The dry powder slurry is discharged through the discharge port and enters the screw feeder 10. The dry powder slurry enters the feed port of the screw feeder 10. The screw feeder 10 transports the dry powder slurry to the discharge port through the rotation of the screw. The dry powder slurry enters the mixing barrel 401 from the discharge port of the screw feeder 10. In the mixing barrel 401, the dry powder slurry is mixed with water and a uniform slurry is formed through the action of the stirring component 4.

[0038] The use of the screw feeder 10 makes the transportation of dry powder slurry more continuous and efficient. The cooperation between the mixing barrel 401 and the screw feeder 10 ensures the full mixing of the dry powder slurry and water, and improves the uniformity of the slurry and the quality of grouting. The process of discharging, conveying and stirring is automated, which reduces manual intervention and reduces labor intensity. The setting of the discharge valve 9 and the screw feeder 10 allows the system to flexibly adjust the discharge and transportation of materials as needed. The design of the screw feeder 10 reduces the wear of materials during the transportation process and improves the reliability and service life of the equipment. The design of the entire system can adapt to different working conditions and improve the scope of application of the automatic suction grouting vehicle 100.

[0039] In some embodiments, the number of the mixing barrels 401 and the discharge ports are both multiple and one-to-one corresponding, and the design of each of the multiple mixing barrels 401 and the discharge ports is:

[0040] There are multiple mixing barrels 401 and one-to-one corresponding discharge ports. This design allows the preparation and output of a variety of different slurries. Each discharge port is provided with a discharge valve 11 for controlling the discharge of the slurry in each mixing barrel 401. Each mixing barrel 401 is provided with a stirring device to ensure that the dry powder slurry is fully mixed with water to form a uniform slurry. Multiple mixing barrels 401 and discharge ports allow multiple slurries to be processed simultaneously, significantly improving production efficiency. Different mixing barrels 401 can be used for the preparation of slurries with different ratios, increasing the flexibility of the system. Each mixing barrel 401 is independently controlled for easy individual maintenance and cleaning.

[0041] In some embodiments, the stirring assembly 4 further includes a horizontal stirrer 402, which is disposed on the stirring barrel 401 and is used to stir the water and dry powder slurry in the stirring barrel 401. The horizontal stirrer 402 is installed on the stirring barrel 401 and is used to stir the water and dry powder slurry in the stirring barrel 401, which can reduce the overall height of the stirring assembly 4 to save space.

[0042] In some embodiments, a water inlet is provided on the mixing barrel 401, and a flow meter 12 is provided at the water inlet.

[0043] The flow meter 12 is installed at the water inlet and is used to detect and monitor the flow rate of water entering the mixing barrel 401 in real time. When the mixing component 4 starts working, water flows into the mixing barrel 401 through the water inlet. The flow meter 12 measures the flow rate of water flowing through the water inlet in real time and transmits the data to the control system. The control system automatically adjusts the opening degree of the water inlet according to the data provided by the flow meter 12 to control the flow rate of water entering the mixing barrel 401. After the dry powder slurry enters the mixing barrel 401 from the screw feeder 10, the control system controls the coordination of the mixing motor and the water inlet according to the preset ratio and the data of the flow meter 12 to ensure the accuracy of the mixing ratio.

[0044] The use of the flow meter 12 enables the water intake to be precisely controlled, ensuring the mixing ratio of the dry powder slurry and water and improving the quality of the slurry. By real-time monitoring and adjusting the flow, the mixing process can be optimized, the mixing efficiency and the uniformity of the slurry can be improved. Automated flow control reduces the need for manual intervention, reduces labor intensity and improves production efficiency. Precise control of the flow helps reduce the waste of water resources and meets the requirements of energy conservation and emission reduction. The flow meter 12 can be adjusted according to different slurry characteristics and requirements, enhancing the mixing system. Precise control of the water intake can reduce the risk of slurry overflow or shortage and improve the safety of the operation.
