[0002] Mine area management refers to the comprehensive management and control of mining activities to reduce environmental damage, ensure safe production and sustainable development. Grouting equipment is indispensable in mine area management. Grouting can effectively prevent water hazards, reinforce strata and surrounding rock, enhance their stability, and prevent accidents such as collapses and roof falls. Grouting equipment generally includes grouting pipes, grouting pumps, and grouting heads. The grouting head is one of the important components of the grouting equipment, which can spray out grout to achieve the purpose of grouting.
[0003] Chinese patent discloses an anti-clogging grouting head (authorization announcement number CN217975425U). This patented technology optimizes the grouting inlet position by combining the grouting structure and the anti-clogging structure, ensuring that the injected cement grout is always mixed in the final step throughout the grouting process, thus preventing cement sludge accumulation and clogging of the grouting head.
[0004] However, existing grouting heads typically inject slurry directly from the head, which can cause splashing during injection, potentially injuring workers and hindering mine remediation efforts. For example, the aforementioned comparative document uses a direct injection method, which, in practical applications, causes splashing when the slurry is ejected from the head, easily injuring nearby workers. Therefore, those skilled in the art have provided a grouting head structure for mine area remediation grouting equipment to address the problems mentioned in the background section.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4This utility model provides a technical solution for the structure of a grouting head in a grouting equipment for mine area remediation: it includes: a grouting device 1, a grouting pipe 11 disposed outside the grouting device 1, a connecting pipe 21 connected to one end of the grouting pipe 11, and a grouting head 2 fixed to one end of the connecting pipe 21. The upper end of the grouting head 2 is threadedly connected to a sealing disc 3, and a sealing groove 34 is formed on the lower surface of the sealing disc 3. An electric telescopic rod 31 is disposed inside the sealing groove 34. An installation sleeve 33 is bolted to the telescopic end of the electric telescopic rod 31. An anti-blocking rod 32 is connected to the lower end of the installation sleeve 33. A connecting sleeve 41 is also sleeved on the outside of the grouting head 2. A shield 4 is installed on the lower surface of the connecting sleeve 41 on the outside of the grouting head 2. This setting uses the shield 4 to shield the sprayed mud, thereby avoiding mud splashing and causing injury to surrounding workers. Furthermore, the setting of the anti-blocking rod 32 enables the grouting head 2 to have an anti-blocking effect, preventing it from becoming blocked and affecting the mine area remediation work.
[0024] like Figure 1 As shown, a grouting pump is installed on the outside of the grouting equipment 1. One end of the grouting pump is connected to the grouting pipe 11, and the other end of the grouting pump is connected to the grouting equipment 1. A sealing sleeve is also installed on the outside of the connecting pipe 21. The sealing sleeve is threaded to the outside of the grouting pipe 11. This arrangement uses the sealing sleeve to achieve the purpose of connecting the grouting pipe 11 and the connecting pipe 21. The grouting pump can extract the mud inside the grouting equipment 1 to carry out the grouting work.
[0025] like Figure 1 and Figure 2 As shown, the connecting sleeve 41 is also symmetrically provided with positioning bolts 44 on the outside, and the grouting head 2 is provided with an installation hole on the outside. The end of the positioning bolt 44 is embedded in the installation hole and threadedly connected to the installation hole. This arrangement can realize the installation and disassembly of the connecting sleeve 41 and the grouting head 2 by using the positioning bolt 44 and the installation hole threadedly connected, which is practical.
[0026] like Figure 2 As shown, the upper surface of the shield 4 is symmetrically provided with positioning pins 42, and the lower surface of the connecting sleeve 41 is provided with positioning holes 43 that engage with the positioning pins 42. This arrangement allows the shield 4 to be installed by embedding the positioning pins 42 into the positioning holes 43, so as to prevent mud splashing.
[0027] like Figure 2 As shown, the upper radius of the shield 4 is the same as the radius of the connecting sleeve 41, and the lower radius of the shield 4 is larger than the radius of the connecting sleeve 41. The shield 4 is arranged in a trumpet shape, which can achieve the purpose of shielding the mud by using the trumpet-shaped shield 4.
[0028] like Figure 4As shown, the grouting head 2 has an external thread on its outside and an internal thread that engages with the external thread on the inside of the sealing groove 34. This arrangement allows the sealing disc 3 to be installed by engaging the external and internal threads.
[0029] like Figure 4 As shown, the lower end of the anti-blocking rod 32 penetrates the lower surface of the grouting head 2, and the lower end of the anti-blocking rod 32 is tapered. This design uses the anti-blocking rod 32 to prevent the grouting head 2 from becoming blocked and affecting the mine area management work.
[0030] The working principle of this utility model is as follows: When using the grouting head structure of the grouting equipment for mine area remediation, the grouting pipe 11 can be connected to the connecting pipe 21 through the sealing sleeve. After connection, the shield 4 can be installed on the lower surface of the connecting sleeve 41 by embedding the positioning pin 42 into the positioning hole 43. After installation, the connecting sleeve 41 can be fixed by the positioning bolt 44. In this way, during the mine area remediation work, the slurry inside the grouting equipment 1 can be extracted by the grouting pump. After extraction, the slurry will enter the grouting head 2 through the grouting pipe 11 to achieve the purpose of grouting. The shield 4 can shield the grouting head 2, thus avoiding slurry splashing and affecting the workers and the mine area remediation work. At the same time, when the grouting head 2 is blocked, the anti-blocking rod 32 can be raised and lowered inside the grouting head 2 by the operation of the electric telescopic rod 31, thereby achieving anti-blocking treatment of the grouting head 2 and avoiding blockage of the grouting head 2, which would affect the mine area remediation work.
[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
