DETAILED DESCRIPTION

[0026] The embodiments of the present application will be described in detail below with reference to the drawings. In the case of no conflict, the following examples and features in the examples can be combined with each other.

[0027] As shown in Figures 1-3 , a precise material falling device according to the embodiments of the present application comprises:

[0028] Chute 1, with a discharge port 2 at its tail end;

[0029] The belt conveyor 3 is located below the material drop port 2. The chute 1 is inclined above the belt conveyor 3. In actual operation, the chute 1 is stably supported by a support frame. Support components and support structures are provided above the chute 1 to support upstream transportation structures such as transfer stations.

[0030] The adjusting plate 4 and the bottom end of the chute 1 are provided with a sliding part 5. The adjusting plate 4 is slidably connected to the discharge port 2 through the sliding part 5, and the adjusting plate 4 can partially cover the discharge port 2.

[0031] Adjustment component 6, the output end of adjustment component 6 is fixedly connected to adjustment plate 4, and adjustment component 6 can adjust the coverage area of ​​adjustment plate 4 at material discharge port 2;

[0032] Safety redundancy component 7 is located at the end of the adjusting plate 4. In use, the adjusting plate 4 slides on the sliding component 5 via the adjusting component 6, thereby adjusting the coverage area of ​​the adjusting plate 4 over the material discharge port 2. This adjusts the drop point of the coal as it falls from the discharge port 2, ensuring the coal accurately lands at the center of the belt conveyor 3. The integrity of the adjusting plate 4 can be observed from the outside at any time. The adjusting component 6 allows for flexible adjustment of the coal drop point, maintaining accuracy under different operating conditions. Furthermore, the safety redundancy component 7 ensures that when overloaded coal passes over the adjusting plate 4, it will not fall onto the belt conveyor 3, preventing additional equipment damage. This solves the problem in existing technologies where the coal drop point cannot be flexibly adjusted, leading to belt misalignment, severe material spillage, and failure to meet rated output; in severe cases, it can cause serious belt misalignment and scraping.

[0033] like Figure 1 As shown, the transport direction of the belt conveyor 3 is not the same as the discharge direction of the discharge port 2. The discharge direction of the discharge port 2 is the side of the belt conveyor 3. If the transport direction of the belt conveyor 3 is front-to-back, the discharge port 2 is left-to-right, which facilitates the adjustment of the position of the coal on the belt conveyor 3.

[0034] like Figure 2 As shown, a guide plate 11 is provided at the tail end of the chute 1 near the discharge port 2. The guide plate 11 has a triangular rounded design. When passing through the guide plate 11, the coal automatically concentrates towards the center, thereby ensuring that the coal can be discharged in a concentrated manner.

[0035] like Figure 3As shown, the sliding member 5 is a channel steel chute 51 fixedly connected to both sides of the tail end of the chute 1, and the adjusting long plate 4 is slidingly connected to the channel steel chute 51, so that the adjusting long plate 4 can partially cover the material fall opening 2. The channel steel chute 51 is connected to the bottom of the chute 1 by welding, and the adjusting long plate 4 is inserted into the groove of the channel steel chute 51 and is located outside the chute 1, so that the installation integrity of the adjusting long plate 4 can be conveniently observed and the adjusting long plate 4 can be conveniently repaired at any time.

[0036] Further, the adjusting member 6 includes an L-shaped bracket 61, a mounting block 62, a nut 63, a rotating lead screw 64, and a rotating motor 65. The L-shaped bracket 61 is fixedly connected to both sides of the bottom end of the chute 1, the mounting block 62 is fixedly connected to both sides of the bottom end of the adjusting long plate 4, the nut 63 is fixedly connected to the mounting block 62, the rotating lead screw 64 is rotatably connected to the nut 63 through the L-shaped bracket 61 and is threadedly rotatably connected to the L-shaped bracket 61, and the output end of the rotating motor 65 is fixedly connected to the end of the rotating lead screw 64. Starting the rotating motor 65 drives the rotating lead screw 64 to rotate on the L-shaped bracket 61, so that the rotating lead screw 64 moves forward and backward, thereby driving the adjusting long plate 4 to move forward and backward at the material fall opening 2, so as to adjust the coverage area of the adjusting long plate 4 at the material fall opening 2, thereby adjusting the material falling position of the coal at the material fall opening 2.

[0037] Further, the safety redundancy member 7 includes a connecting long pipe 71, an ear 72, and a steel wire rope 73. The connecting long pipe 71 is fixedly connected to the adjusting long plate 4, the ear 72 is fixedly connected to both sides of the connecting long pipe 71, one end of the steel wire rope 73 passes through the ear 72, and the other end of the steel wire rope 73 is fixedly connected to a support bracket above. It is to be noted that the other end of the steel wire rope 73 is fixedly connected to a support bracket of an upstream conveying structure, so that the steel wire rope 73 is connected up and down. An upstream support bracket 8 is arranged above the chute 1, and the other end of the steel wire rope 73 is fixedly connected to the upstream support bracket 8. It is to be noted that in actual use, the chute 1 and the upstream conveying device are both provided with support brackets for supporting. The upstream support bracket 8 is fixedly connected with a fixing ear 74, and the other end of the steel wire rope 73 passes through the fixing ear 74. The steel wire rope 73 is taut on the adjusting long plate 4. When the coal transported is too much, the adjusting long plate 4 cannot bear the gravity of the coal at this time, forming an overload. At this time, the adjusting long plate 4 is pulled by the steel wire rope 73, so as to prevent the adjusting long plate 4 from falling onto the belt conveying member 3 due to overload, thereby causing additional equipment loss.

[0038] As shown in FIG. 1, Figure 2 The tail end of the chute 1 is designed in a rounded shape. The rounded design makes the tail end of the chute 1 smoother, so that the coal can better fall to the material fall opening 2.

[0039] In conclusion, the working principle of the precise blanking device is as follows: during use, the rotating motor 65 is started to drive the rotating screw rod 64 to rotate on the L-shaped support 61, so that the rotating screw rod 64 moves forward and backward, thereby driving the adjusting long plate 4 to slide in the channel steel chute 51, so as to adjust the covering area of the adjusting long plate 4 covering the blanking opening 2, thereby adjusting the falling point of the coal falling from the blanking opening 2, so that the coal can accurately fall to the center position of the belt conveyor 3, the integrity of the adjusting long plate 4 can be observed from the outside at any time, the falling point of the coal can be flexibly adjusted by the rotating screw rod 64, so that the accuracy of the coal falling point is maintained under different working conditions, and the adjusting long plate 4 is pulled by the steel wire rope 73 to ensure that the adjusting long plate 4 will not fall on the belt conveyor 3 to cause additional equipment loss when the overloaded coal passes through the adjusting long plate 4, the problem that the coal falling point cannot be flexibly adjusted in the prior art is solved, the belt machine is prone to deviation, the leakage is serious, the rated output cannot be met, and the serious problem that the belt is seriously deviated and scratched is solved.
