[0039] According to a first aspect of the present invention, see Figures 1 to 4 , provides a concrete unloading system for use in mines, comprising a filling layer 1, a protective steel pipe 2, a transport steel pipe 3, a pouring chute 4 and a material receiving unit;

[0040] A hole is drilled into the mine at a preset position on the ground to form an installation hole, the protective steel pipe 2 is installed in the installation hole, and the filling layer 1 is arranged between the hole wall 6 of the installation hole and the outer wall of the protective layer; the transport steel pipe 3 is installed on the inner side of the protective steel pipe 2;

[0041] The top of the transport steel pipe 3 is detachably connected to a material pouring trough 4, and the material pouring trough 4 is located above the ground surface; the bottom of the transport steel pipe 3 is connected to a material receiving unit;

[0042] The transport vehicle is located below the receiving unit to receive the concrete delivered by the receiving unit, that is, the concrete passes through the pouring chute 4, the transport steel pipe 3, and the receiving unit in sequence and enters the transport vehicle.

[0043] In the embodiment of the present application, the operation of the concrete unloading system applied to the mine realizes the shortest vertical distance transportation of mine concrete from the ground to the underground through the pipe hole (that is, the transport steel pipe 3), effectively improves the average daily transportation capacity of concrete, saves a lot of transportation costs, and at the same time reduces the frequency of vehicles (that is, transport vehicles) passing through the secondary inclined shaft for explosion-proof materials, reduces the exhaust emissions of transport vehicles, and has the effect of eliminating the safety hazard of vehicle stalling on slopes and improving the efficiency of concrete transportation.

[0044] Optionally, the concrete unloading system applied to the mine further includes a ground insulation room;

[0045] A ground insulation room is constructed outside the installation hole, and the entrance of the pouring chute 4 is located in the ground insulation room.

[0046] In the above implementation, the ground insulation room can be used to keep materials warm in winter and facilitate standardized management.

[0047] Optionally, the concrete unloading system applied to the mine further includes a hydraulic cover plate 7;

[0048] The hydraulic cover plate 7 is openably and closably disposed at the entrance of the pouring chute 4 .

[0049] In the above embodiment, the hydraulic cover plate 7 can prevent debris from entering the discharge hole of the pouring chute 4, and can effectively control the material delivery amount during the concrete discharge process.

[0050] Optionally, a hydraulic gate 8 is provided at the top port of the transport steel pipe 3;

[0051] The top port of the transport steel pipe 3 is opened or closed by the hydraulic gate 8 .

[0052] In the above embodiment, the discharge amount of concrete can be effectively controlled by the hydraulic gate plate 8, and the operation is simple and convenient.

[0053] Alternatively, see Figure 2 and Figure 3 , the mounting hole comprises a first portion and a second portion, the first portion is located above the second portion;

[0054] The first portion is located in the topsoil layer, and the second portion is located in the bedrock layer;

[0055] The protective steel pipe 2 is embedded in the first part; the lower part of the transport steel pipe 3 is embedded in the second part of the installation hole.

[0056] In the above embodiment, according to the different characteristics of the topsoil layer and the bedrock layer, since the bedrock layer has sufficient bearing capacity, the transport steel pipe 3 is directly set in the drill hole of the bedrock layer, which helps to ensure the stability and safety of the concrete unloading system used in the mine, and also helps to optimize the construction process and reduce costs.

[0057] Alternatively, see Figure 4 , the concrete feeding system applied to the mine also includes a fixed steel plate 9;

[0058] The fixing steel plate 9 is connected to the bottom of the transport steel pipe 3 , and the fixing steel plate 9 is fixed to the roof of the tunnel 13 in the mine through an anchor cable 12 .

[0059] In the above embodiment, the fixed steel plate 9 helps to ensure the stability of the transported steel pipe 3 .

[0060] Optionally, the concrete feeding system applied to a mine further includes a rib plate 10;

[0061] The fixing steel plate 9 is provided with ribs 10, and the ribs 10 are arranged around the bottom outer side of the transport steel pipe 3. This can improve the fixing strength of the fixing steel plate 9.

[0062] Optionally, the filling layer 1 is made of cement mortar, which can better protect the transport steel pipe 3.

[0063] Optionally, a casting foundation 11 is provided on one side of the transport pipeline close to the pouring trough 4. The casting foundation 11 helps to ensure the stability of the drilling process and also helps to better fix the transport steel pipe 3.

[0064] Optionally, the inclination angle of the mounting hole is not greater than 1.5 degrees, which helps to ensure the stability of the concrete feeding process.

[0065] Exemplarily, the top of the transport steel pipe 3 is fixed in the casting foundation 11 by a fixing steel plate 9 , and a rib plate 10 is provided on the fixing steel plate 9 , and the rib plate 10 is arranged around the outer side of the top of the transport steel pipe 3 .

[0066] It should be noted that due to the large relative height difference between the surface and the output port of the underground concrete, the material (i.e., concrete) falls rapidly in the transport steel pipe 3, causing a large amount of material splashing at the receiving port, and cannot smoothly enter the vehicle. The receiving unit can effectively solve the problem of splashing caused by the large impact force of the material at the receiving port in the early stage of operation, ensuring the optimal operation of the system. The device has an automatic opening and closing gate controlled by a hydraulic system, which can control the height of the receiving port while controlling the material loading amount, meeting the use needs of various types of concrete transportation vehicles.

[0067] In a specific implementation, the concrete feeding system used in mines has built a ground insulation room, a ground material conveying control device, and a feeding casing from the ground to the underground. At the same time, multiple projects such as underground loading channels, dredging drainage ditches, and underground automatic material receiving devices are constructed underground, and finally a complete concrete feeding system is formed. It fully considers factors such as ground construction sites, feeding hole construction, underground transportation routes, material delivery safety, feeding equipment automation, and winter material warmth, and thus formulates a construction plan for the underground and underground auxiliary systems and loading channels.

[0068] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
