[0035] The present invention will be further described in detail below with reference to specific embodiments, but the implementation manner of the present invention is not limited thereto.

[0036] See also Figures 1 to 4 The utility model provides a grouting device, including: a stirring device 100, a storage hopper 200, a feeding mechanism 300 and a frame 700.

[0037] The stirring device 100 is fixed on the upper part of the frame 700 and is used for stirring materials.

[0038] The storage hopper 200 is fixed on the frame 700 and is located below the stirring device 100, and is used to receive the material leaked from the stirring device 100. The storage hopper 200 is equipped with a liquid level detection device at a suitable position to detect the liquid level in the storage hopper 200.

[0039] The feeding mechanism 300 is fixed at the lower part of the frame 700 and is located below the storage hopper 200, and is used to transport the material in the storage hopper 200 to the subsequent grouting pipe (not shown in the figure), and then the grouting pipe delivers the material to the place where grouting construction is required.

[0040] Furthermore, the grouting equipment of the present invention further comprises a control cabinet 400, which comprises a PLC controller 410 and a control panel 420. The control panel 420 is connected to the input end of the PLC controller 410, and corresponding parameters can be set through the control panel 420.

[0041] In a preferred embodiment of the present invention, the stirring device 100 includes a stirring barrel 110, a stirring shaft (not shown in the figure), a stirring blade (not shown in the figure) and a stirring motor 140. Figure 1 The mixing barrel 110 is fixed to the upper part of the frame 700, and a mesh plate 114 is provided on the top thereof to filter materials with larger particles, and a discharge port 111 is provided on the bottom. The discharge port 111 corresponds to the opening area on the upper part of the storage hopper 200, and the discharge port 111 is equipped with a discharge valve (not shown in the figure). The stirring shaft is arranged in the mixing barrel 110. The stirring blades are arranged around the stirring shaft. The stirring motor 140 is fixed to the mixing barrel 110 or to the frame 700. The stirring motor 140 is connected to the stirring shaft through a reducer (not shown in the figure) for driving the stirring shaft to rotate and stir the material in the mixing barrel 110. At the same time, the stirring motor 140 is also electrically connected to the output end of the PLC controller 410.

[0042] The stirring device 100 is also equipped with a water inlet pipe 112 for adding water to the stirring drum 110. A flow meter 113 is provided on the water inlet pipe 112 and is electrically connected to the input of the PLC controller 410. Before stirring, the water inlet volume of the stirring drum 110 can be set on the control panel 420, and the flow meter 113 then controls the water inlet volume.

[0043] Preferably, the discharge valve is a solenoid valve 115 , which is electrically connected to the output end of the PLC controller 410 . The PLC controller 410 can control the opening and closing of the solenoid valve 115 to control the discharge situation of the stirring device 100 .

[0044] In a preferred embodiment of the present invention, the feeding mechanism 300 includes a screw feeder 310 and a screw pump 320. The screw feeder 310 is disposed below the storage hopper 200. The top of the screw feeder 310 serves as the feed inlet. The spiral blades of the screw feeder 310 can be driven to rotate by a feeding motor 311 disposed on one side. The feed end of the screw pump 320 is connected to the discharge end of the screw feeder 310, and the discharge end of the screw pump 320 is connected to the grouting pipe. Both the feeding motor 311 and the screw pump 320 are electrically connected to the output end of the PLC controller 410 and can be started or stopped by the PLC controller 410.

[0045] In addition, the grouting pipe is provided with a flow sensor 510 and a pressure sensor 520. The flow sensor 510 and the pressure sensor 520 are electrically connected to the input end of the PLC controller 410, and can transmit the material flow information and pressure information of the grouting pipe to the PLC controller 410.

[0046] In a preferred embodiment of the present invention, the liquid level detection device uses a liquid level sensor 610. The liquid level sensor 610 is electrically connected to the input terminal of the PLC controller 410 and can transmit the material level information in the storage hopper 200 to the PLC controller 410. During operation, a threshold value can be set in advance for the liquid level of the material in the storage hopper 200. If the liquid level sensor 610 detects that the liquid level in the storage hopper 200 is lower than the preset threshold value, the PLC controller 410 can control the feeding motor 311 and the screw pump 320 to suspend operation based on the detection result of the liquid level sensor 610. When the feeding mechanism 300 suspends operation, once the stirring device 100 resumes feeding, if the liquid level sensor 610 detects that the liquid level in the storage hopper 200 is higher than the preset threshold value, the PLC controller 410 can control the feeding motor 311 and the screw pump 320 to start and resume operation based on the detection result of the liquid level sensor 610.

[0048] Of course, in addition to the liquid level sensor 610, other types of liquid level detection devices may be used as the liquid level detection device and installed at a suitable location in the storage hopper 200. The location of the liquid level detection device should be selected to ensure that the material is not insufficient or lacking during the operation of the feeding motor 311 and the screw pump 320, thereby ensuring the effective operation of the equipment.

[0049] In the present invention, since a liquid level detection device is provided, when the grouting equipment encounters a shortage of material or insufficient material during operation, the liquid level detection device will promptly know that the liquid level in the storage hopper 200 is lower than the preset threshold value, and then transmit this information to the PLC controller 410. The PLC controller 410 then controls the feeding motor 311 and the screw pump 320 to suspend operation, thereby avoiding the idling phenomenon of the feeding mechanism 300 and protecting the corresponding components from damage due to idling, thereby extending the service life of the equipment and achieving the effect of increasing efficiency.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
