[0037] Please refer to Figures 1 to 4 , the present invention provides a continuous excavation and filling carrier device for coal mines, including:

[0038] The first pipe body 1, which is vertically embedded in the first conveying well;

[0039] The second pipe body 2, which is vertically embedded in the second conveying well, and the second conveying well is located on one side of the first conveying well;

[0040] The transmission wheels 3 that are symmetrically arranged up and down and can rotate, and a chain 4 is drivingly connected between the two transmission wheels 3, and the chain 4 penetrates through the first pipe body 1 and the first pipe body 2; and

[0041] A plurality of one-way support assemblies 5 arranged in an array on the chain 4, which are used to extend and support the filling body in the first pipe body 1 and be received in the second pipe body.

[0042] Furthermore, the first pipe body 1 has a first inner diameter, the second pipe body 2 has a second inner diameter, and the second inner diameter is smaller than the first inner diameter.

[0043] That is to say, in this embodiment, through the cooperation of the transmission wheel, the chain and the one-way support assembly 5, the filling bodies can be supported one by one and sent into the roadway for conveying so as to be sent to the goaf for filling. And, since the one-way support assembly 5 can extend and support the filling body in the first pipe body and be received in the second pipe body, the second inner diameter of the second pipe body can be configured to be smaller than the first inner diameter of the first pipe body, thereby greatly reducing the construction amount and reducing the investment in pipe bodies.

[0044] In this embodiment, as Figure 2 , the one-way support assembly 5 includes:

[0045] The sliding seat 51, one end of which is connected to the chain 4 and the other end is hinged with the support arm 52;

[0046] A plurality of mounting plates 53 arranged in an array along the length direction of the support arm 52, wherein the mounting plates 53 are fixed on the support arm 52;

[0047] A support arm 54 disposed on the mounting plate 53; and

[0048] The limiting arm 58 is disposed at one end of the mounting plate 53 away from the support arm 54 . The limiting arm 58 can be supported by a one-way support seat 510 . The one-way support seat 510 is fixed to one side of the sliding seat 51 .

[0049] In addition, a lightweight limiting plate 511 is fixed on the sliding seat 51, and when the support arm 52 is located in the first tube body 1, the one-way support seat 510 and the limiting arm 58 provide limiting and support for it; when the support arm 52 is located in the second tube body 2, the lightweight limiting plate 511 provides limiting and support for it.

[0050] As a preferred embodiment, one end of the limit arm 58 is hinged to the support plate 57, and the other end is a free end. The support plate 57 is fixed to the middle part of the support arm 52, and an adjustment rod 59 is hinged between the limit arm 58 and the support plate 57.

[0051] The inclination angle of the limiting arm 58 can be adjusted by telescopic adjustment of the adjusting rod 59, thereby changing the inclination angle of the support arm 52 when the support arm 52 is located in the first tube body 1, so as to adapt to different material discharge requirements.

[0052] As a preferred embodiment, the support arm 54 is connected to the mounting plate 53 by rotating around the R axis, a telescopic rod 55 is fixed to one end of the support arm 54 away from the support arm 52, a support pad 56 is fixed to the output end of the telescopic rod 55, and a chain is used to connect two adjacent support pads 56. The length of the chain between two adjacent support pads 56 is sufficient to allow the support pads 56 to move a certain distance; and by driving the support arm 54 to rotate, the distribution of its support points can be dispersed as a whole to ensure the overall support.

[0053] As a preferred embodiment, the one-way support seat 510 has a support groove.

[0054] In this embodiment, a limiting track 21 distributed along the axial direction is fixed to the side where the first tube body 1 and the second tube body 2 are close to each other. The limiting track 21 is I-shaped, and the sliding seat 51 is groove-shaped. The limiting blocks are symmetrically fixed at the groove, which are used to be connected with the limiting track 21 for sliding and limiting.

[0055] In this embodiment, Figure 3 and 4A gap transmission component 6 is disposed below the first tube body 1, a vibration reduction component 7 is disposed at the bottom of the gap transmission component 6, and the gap transmission component 6 includes:

[0056] A plurality of wheel seats 62 distributed in an array, wherein the wheel seats 62 are fixed on the bottom plate 61 by using columns 63;

[0057] Synchronous wheels 64 symmetrically rotatably disposed on the wheel seat 62, and a synchronous belt 66 is also connected between the two synchronous wheels 64; and

[0058] A driving wheel 65 for driving the synchronous belt 66 to rotate;

[0059] The plurality of driving wheels 65 are coaxially fixedly connected and driven by an external motor.

[0060] By configuring a plurality of wheel seats 62 distributed in an array, the gaps between the wheel seats can be used to cut the filling body during the process of conveying the filling body. Specifically, the filling body often includes processed gangue, fly ash, etc. When conveyed from top to bottom, it is packaged in a bag to ensure that the filling body does not scatter everywhere. When the filling body falls into the gap conveying component 6, the bag can be cut by the knife body (not shown in the figure) between the wheel seats 62, so that it scatters naturally, which is convenient for subsequent conveying through the horizontal conveying component 8.

[0061] In this embodiment, the vibration reduction assembly 7 includes:

[0062] Two groups of vibration reduction chambers 72 are symmetrically arranged, and each group of vibration reduction chambers 72 is a plurality of chambers arranged in an array;

[0063] A vibration reduction arm 71, the bottom of which is slidably disposed in the vibration reduction chamber 72 by a piston seal, and the top of which is connected to the bottom plate 61;

[0064] A branch pipe 73, one end of which is connected to the bottom of the vibration reduction chamber 72, and the other end of which is collected in the air supply pipe 74, and a one-way valve is provided on the air supply pipe 74 so that the gas can enter the branch pipe 73 in one direction; and

[0065] The pressure relief pipe 75 is connected to the side of the vibration reduction chamber 72 and is collected in a pressure relief main pipe. A pressure relief valve is provided on the pressure relief main pipe.

[0066] In this embodiment, gas can be supplied to the gas supply pipe 74 through an external gas supply device, and then the gas enters each vibration reduction chamber 72 through the branch pipe 73 to provide gas vibration reduction for the vibration reduction chamber 72 .

[0067] In specific implementation, through the cooperation of the transmission wheel, the chain and the one-way support assembly 5, the filling bodies can be supported one by one in the first pipe body. Then, when the filling body is located below the first pipe body, due to the deflection of the one-way support assembly 5, the filling body falls onto the gap transmission assembly 6, and the damping assembly 7 provides buffering. After that, the filling body enters the horizontal transmission assembly 8 after cutting and blanking, so as to realize the transportation in the roadway and be sent to the gob area for filling.

[0068] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
