Description

Technical Field

[0001] The utility model relates to the technical field of coal mine transportation equipment, in particular to a middle trough flushing mechanism of a scraper. Background Art

[0002] Due to the limited space and hazardous environment in underground coal mines, fully mechanized mining and transportation equipment must be easy to use, cost-effective, safe, and reliable. When the scraper's middle trough transports coal, a small amount of coal slag accumulates on its bottom plate, which needs to be flushed clean. The existing scraper flushing method is to flush water directly into the bottom plate through the flushing holes on the trough side. However, due to the varying sizes of the flushing holes, flushing is inconvenient. The water pipe is easily dislodged when it is stuck in the flushing hole, resulting in a waste of water resources. The flushing personnel have to hold the flushing hand all the time, which results in a waste of manpower and reduced work efficiency. In addition, water spilling next to the machine during flushing can make the road surface slippery, posing a safety hazard to personnel passing by. In order to fundamentally solve the problems of poor safety of flushing in the middle trough, waste of water resources, and waste of personnel, a flushing mechanism is needed. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a scraper middle tank flushing mechanism, in which a connecting pipe is fixed to the flushing hole, a joint is provided at one end of the connecting pipe away from the middle tank, and the joint is connected to the external water pipe. No personnel supervision is required during flushing and the water pipe will not fall off.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a scraper middle trough flushing mechanism, including a middle trough, a flushing hole for connecting the inner and outer spaces on the side of the middle trough, and a connecting component arranged in the flushing hole; the connecting component includes a connecting pipe fixedly arranged in the flushing hole, and a joint connected to one end of the connecting pipe located outside the middle trough.

[0005] Preferably, the flushing hole is located between the bottom plate and the middle plate of the middle trough.

[0006] Preferably, the connecting pipe includes a positioning pipe fixedly connected to the flushing hole and a joint portion integrally provided with the positioning pipe and fixedly connected to the joint.

[0007] Preferably, the connecting pipe includes a positioning pipe fixedly connected to the flushing hole and an expanding pipe or a bundled pipe integrally provided with the positioning pipe.

[0008] Preferably, the connecting pipe includes a positioning pipe fixedly connected to the flushing hole and an expanding pipe integrally arranged with the positioning pipe at one end away from the middle groove; the inner diameter of the equal-section diameter pipe corresponding to the expanding pipe is equal to the maximum inner diameter of the expanding pipe; the equal-diameter pipe is provided with an internal thread or an external thread, and the equal-diameter pipe is threadedly connected to one end of the joint through the internal thread or the external thread.

[0009] Preferably, the connecting pipe includes a positioning pipe fixedly connected to the flushing hole and a bundled-end pipe integrally arranged with the positioning pipe at one end away from the middle groove; the inner diameter of the equal-section diameter pipe corresponding to the bundled-end pipe is equal to the minimum inner diameter of the expanded pipe; the equal-diameter pipe is provided with an internal thread or an external thread, and the equal-diameter pipe is threadedly connected to one end of the joint through the internal thread or the external thread.

[0010] Preferably, the model of the connector is KJ10, the connector is threadedly connected to the connecting pipe, and the connecting pipe is welded to the inner wall of the flushing hole.

[0011] The beneficial effects of the utility model are as follows: the utility model fixes a connecting pipe at the flushing hole, and provides a joint at the end of the connecting pipe away from the middle groove. The joint is connected to the external water pipe, and no personnel supervision is required during flushing, and the water pipe will not fall off, thereby improving work efficiency; if the water pipe does not fall off, water will not flow on the road surface, and water resources will not be wasted, thereby improving the safety of the working environment.

[0015] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0016] Example 1:

[0017] like Figure 1-Figure 2 As shown, a scraper middle tank flushing mechanism includes a middle tank 1, a flushing hole 2 is opened on the side of the middle tank 1 for connecting the inner and outer spaces, and a connecting component is arranged in the flushing hole 2; the connecting component includes a connecting pipe 3 fixedly arranged in the flushing hole 2, and a joint 4 connected to one end of the connecting pipe 3 located outside the middle tank 1.

[0018] The flushing hole 2 is located between the bottom plate and the middle plate of the middle tank 1.

[0019] The connecting pipe 3 includes a positioning pipe fixedly connected to the flushing hole 2 and a joint portion integrally provided with an end of the positioning pipe away from the middle groove 1 and fixedly connected to the joint 4 .

[0020] The model of the joint 4 is KJ10, the joint 4 is threadedly connected to the connecting pipe 3, and the connecting pipe 3 is welded to the inner wall of the flushing hole 2.

[0021] Example 2:

[0022] What is different from Example 1 is that the connecting pipe 3 includes a positioning pipe fixedly connected to the flushing hole 2 and a flaring pipe integrally arranged with the positioning pipe at one end away from the middle groove 1; the inner diameter of the equal-section diameter pipe corresponding to the flaring pipe is equal to the maximum inner diameter of the flaring pipe; the equal-diameter pipes are provided with internal threads or external threads, and the equal-diameter pipes are threadedly connected to one end of the joint 4 through the internal threads or external threads, and the other end of the joint 4 is fixedly connected to the external water pipe; the flaring pipe refers to a pipe whose diameter gradually increases as it extends from the positioning pipe toward the direction away from the middle groove 1.

[0023] One end of the flared pipe away from the positioning pipe is connected to a pipe with a uniform cross-sectional diameter.

[0024] Example 3:

[0025] What is different from Example 1 is that the connecting pipe 3 includes a positioning pipe fixedly connected to the flushing hole 2 and a bundled-end pipe integrally arranged with the positioning pipe at one end away from the middle groove 1; the inner diameter of the equal-section diameter pipe corresponding to the bundled-end pipe is equal to the minimum inner diameter of the expanded pipe; the equal-diameter pipes are provided with internal threads or external threads, and the equal-diameter pipes are threadedly connected to one end of the joint 4 through the internal threads or external threads, and the other end of the joint 4 is fixedly connected to the external water pipe; the bundled-end pipe refers to a pipe whose diameter gradually decreases as it extends from the positioning pipe toward away from the middle groove 1.

[0026] One end of the bundled tube away from the positioning tube is connected to a pipe with a uniform cross-sectional diameter.

[0027] The design of the expanded pipe and the bundled pipe is to adapt to different types of joints and flushing holes 2 with different inner diameter standards, so that the scraper middle tank flushing mechanism has a wider range of adaptability; the setting of the pipe with a constant cross-sectional diameter is to facilitate the threaded connection with the joint 4;

[0028] Example 4:

[0029] What is different from Example 1 is that when facing flushing holes 2 with different inner diameter standards, the medium cross-sectional diameter pipe of Example 2 or Example 3 can be welded to the flushing hole 2 according to actual conditions, and an internal thread or an external thread can be set on the positioning pipe to fix the positioning pipe to the joint 4.
