The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1

[0025] The preferred embodiment of the coal drop hopper anti-leakage device provided by the utility model is as follows Figure 1-5 The figure shows a device for preventing coal leakage in a coal drop shaft, comprising a coal drop shaft 111. An arc-shaped groove is provided in the middle of the outer wall of the coal drop shaft 111, a material discharging assembly 2 is provided in the middle of the interior of the coal drop shaft 111, and a coal leakage prevention assembly 3 is provided on the top of the coal drop shaft 111. A sliding trough body is integrally connected to the middle of the interior of the coal drop shaft 111.

[0026] The material discharging assembly 2 specifically includes the following structures: an arc-shaped groove seat 211, fixedly installed in the arc-shaped groove; a toggle rod 212, set in the arc-shaped groove seat 211;

[0027] One end of the toggle rod 212 extends into the interior of the coal drop shaft 111, and one end of the toggle rod 212 is fixedly connected to a rotating disk 213, which is movably connected to the sliding trough body. The top of the rotating disk 213 is adapted to be installed with an inclined flow platform 214, and a leakage disk frame 216 is provided on the top of the inclined flow platform 214. The leakage disk frame 216 is fixedly installed on the inner wall of the coal drop shaft 111, and the inclined flow platform 214 and the leakage disk frame 216 are rotatably connected via a rotating shaft 215.

[0028] A steel ball groove 217 is provided on the rotating disk 213 and the inclined flow platform 214, and a steel ball 218 is built into the steel ball groove 217. A compression spring 219 is fixedly connected between the top of the steel ball 218 and the top of the drain disk frame 216.

[0029] The rotating disk 213 is provided with slag flow holes 2111 at equal intervals on its circumference, and the leakage disk frame 216 is provided with slag leakage holes 2110 at equal intervals on its circumference.

[0030] In this embodiment, when debris falls from the leakage disk rack 216, the debris falls onto the inclined flow table 214 through the debris leakage hole 2110. When too much debris accumulates on the inclined flow table 214, the toggle rod 212 is repeatedly rotated, and the toggle rod 212 drives the rotating disk 213 to rotate, so that the inclined flow table 214 on the rotating disk 213 rotates accordingly. During this process, the steel ball 218 is repeatedly disengaged from the steel ball groove 217 under the compression of the compression spring 219, thereby driving the debris on the inclined flow table 214 to oscillate, so that the debris gradually falls from the debris flow hole 2111, achieving the effect of thinning the material.

[0031] Example 2

[0032] See also Figure 1-Figure 5 , and on the basis of Example 1, it is further obtained that: the anti-leakage coal assembly 3 specifically includes the following structures: an inner casing 311, which is sleeved on the inner wall of the coal drop shaft 111; a grid plate 312, which is fixedly installed on the bottom of the inner casing 311;

[0033] A semicircular convex ring 313 is fixedly installed on the top of the inner casing 311, and a clamping ring groove seat 314 is fixedly installed on the inner side of the top of the inner casing 311, and the clamping ring groove seat 314 has a matching clamping ring 315 built in;

[0034] A second movable seat 317 is fixedly mounted on the back of the coal drop shaft 111. A connecting arm 318 is movably connected to the second movable seat 317. The other end of the connecting arm 318 is movably connected to a first movable seat 316. The first movable seat 316 is fixedly mounted on the clamping ring 315.

[0035] A lock box 321 is fixedly installed on the top of the coal drop shaft 111. The lock box 321 is located on one side of the semicircular convex ring 313.

[0036] An elastic U-shaped clip 322 is fixedly installed at the middle position inside the lock box 321, and a locking tooth block 1 323 is in contact with both sides of the elastic U-shaped clip 322. The other side of the locking tooth block 1 323 is meshed with a locking tooth block 2 324 between one side of the inner wall of the lock box 321. One end of the locking tooth block 2 324 passes through one side of the inner wall of the lock box 321 and one side of the semicircular convex ring 313 in sequence and extends to the outside, and is fixedly connected to the switch valve plate 325. A switch valve shaft 326 is fixedly connected to the middle position of the switch valve plate 325. The other end of the switch valve shaft 326 passes through the semicircular convex ring 313 and the lock box 321 in sequence and extends to the interior of the lock box 321; a pinching block 327 is fixedly connected to the top of the locking tooth block 1 323.

[0037] In this embodiment, an inner casing 311 is provided on the inner wall of the coal drop shaft 111 to greatly buffer the coal flow from touching the inner wall of the coal drop shaft 111, thereby preventing the inner wall of the coal drop shaft 111 from being frequently broken through and damaged by the coal flow. At the same time, a mesh plate 312 is installed at the bottom of the inner casing 311. The mesh plate 312 has a thickness of 0.10 meters and is composed of 54 small grids of 0.15 meters × 0.15 meters × 0.1 meters. During operation, the coal flow falls into the mesh plate 312, filling the mesh plate 312 to form a protective film, thereby achieving the effect of preventing coal leakage, preventing the coal drop shaft from being frequently worn, reducing the number of coal leakages in the coal drop shaft of the coal conveyor belt, protecting the environment, and ensuring the safe operation of the coal conveying system.

[0038] In this embodiment, when the mesh plate 312 needs to be removed, the user pinches the pinching block 327 by hand, and the pinching block 327 drives the locking tooth block 1 323 to squeeze the elastic U-shaped clamp 322 against each other, and the elastic U-shaped clamp 322 undergoes elastic deformation. At this time, the locking tooth block 1 323 is disengaged from the engagement state with the locking tooth block 2 324. At this time, the user pulls out the switch valve plate 325, which can drive the switch valve shaft 326 to be pulled out, and then pulls out the clamping ring 315 in the clamping ring groove seat 314, finally realizing the disassembly and replacement of the mesh plate 312, thereby preventing the mesh plate 312 from being damaged by the coal flow for a long time.

[0039] Working principle: When it is necessary to remove the grid plate 312, the user pinches the pinching block 327 by hand, and the pinching block 327 drives the locking tooth block 1 323 to squeeze the elastic U-shaped clip 322 against each other, and the elastic U-shaped clip 322 undergoes elastic deformation. At this time, the locking tooth block 1 323 is out of engagement with the locking tooth block 2 324. At this time, the user pulls out the switch valve plate 325, which can drive the switch valve shaft 326 to be pulled out. Then, the clamping ring 315 is pulled out from the clamping ring groove seat 314, and finally the grid plate 312 is disassembled and replaced. Conversely, the grid plate 312 is installed. When there is debris from the grid plate 312, The plate 312 falls on the leakage disk rack 216, and the debris falls onto the inclined flow table 214 through the debris leakage hole 2110. When too much debris accumulates on the inclined flow table 214, the toggle rod 212 is repeatedly rotated to drive the rotating disk 213 to rotate, so that the inclined flow table 214 on the rotating disk 213 rotates accordingly. During this process, the steel ball 218 is repeatedly disengaged from the steel ball groove 217 under the compression of the compression spring 219, thereby driving the debris on the inclined flow table 214 to oscillate, so that the debris gradually falls from the debris flow hole 2111, which is convenient for later collection and recycling.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
