Abstract
Description
Technical Field
[0001] This utility model relates to a sampler, specifically a coal sampler, belonging to the technical field of coal sampling devices. Background Technology
[0002] Steel plants require a large amount of coal in the steelmaking process, so they need to purchase a lot of coal. Before purchasing, the coal needs to be sampled and tested to ensure that the steelmaking boiler can operate safely and economically during the steelmaking process.
[0003] However, traditional coal samplers use a screw conveyor to feed coal into the sampling bottle during the sampling process. After the sampling bottle is full, a large amount of coal dust remains inside the sampler and cannot be discharged. During the next sampling, the coal dust from the previous sampling will enter the next sampling bottle, affecting the detection results of the coal dust in the next sampling. At the same time, since the screw conveyor is located inside the sampler, it is inconvenient to clean. After long-term use, coal dust will adhere to its surface, thus affecting the sampling efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a coal sampler to solve the above-mentioned problems. After a sampling is completed, the residual coal powder inside the sampler can be cleaned quickly and timely to avoid affecting the next sampling. At the same time, it can facilitate the cleaning of the screw rod, avoiding a large amount of coal adhering to the screw rod and ensuring the sampling efficiency.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a coal sampler, including a sampling cylinder, a rotating plate rotatably connected to the sampling cylinder, a connecting block fixedly connected to the sampling cylinder, a sampling structure provided on the connecting block, a blocking structure provided on the connecting block, the blocking structure including multiple guide posts, multiple guide posts threadedly connected to the connecting block, the same retaining ring slidably connected to the multiple guide posts, and a hook plate rotatably connected to the connecting block.
[0006] Preferably, a return spring is sleeved on the outside of the guide post, one end of the return spring abuts against the connecting block, and the other end of the return spring abuts against the retaining ring.
[0007] Preferably, the plurality of guide posts are arranged in a circumferential array about the center of the retaining ring, and one end of the cross-section of the guide post has a T-shaped structure.
[0008] Preferably, one end of the retaining ring cross-section is funnel-shaped, and one end of the hook plate cross-section is L-shaped.
[0009] Preferably, two handles are fixedly connected to the connecting block, and a protrusion is fixedly connected to the rotating plate.
[0010] Preferably, the sampling structure includes a spiral rod, which is rotatably connected to the connecting block, and a crank handle is fixedly connected to one end of the spiral rod.
[0011] Preferably, the crank handle has a Z-shaped structure, and one end of the sampling cylinder cross-section is inclined.
[0012] Preferably, the sampling cylinder is provided with a collection structure, the collection structure includes a collection bucket, the sampling cylinder is threadedly connected to the collection bucket, the bottom end of the collection bucket is threadedly connected to a baffle, and a transparent plate is fixedly connected to one side of the collection bucket.
[0013] The beneficial effects of this utility model are as follows: A rotating plate is rotatably connected to the sampling cylinder, and a connecting block is fixedly connected to the sampling cylinder. The connecting block is equipped with a sampling structure, and multiple guide posts are threadedly connected to the connecting block. The same retaining ring is slidably connected to the multiple guide posts, and a hook plate is rotatably connected to the connecting block. After one sampling is completed, the retaining ring can be pulled, and the retaining ring slides on the multiple guide posts. Multiple return springs retract, continuously pushing the retaining ring until one side of the retaining ring is located inside the hook plate. At this time, the retaining ring is released. Since the end of the hook plate cross-section has an L-shaped structure, the multiple return springs will not extend and drive the retaining ring to return to its original position under the action of the hook plate. At this time, the retaining ring will not block the rotating plate, so the rotating plate can be rotated. After the rotating plate rotates, it will not block the remaining coal powder inside the sampling cylinder, thus facilitating the rapid removal of the remaining coal powder inside the sampling cylinder and avoiding affecting the next sampling. At the same time, after the rotating plate rotates, it will not block the sampling structure, which facilitates the cleaning of the sampling structure and avoids a large amount of coal powder adhering to the sampling structure, ensuring the efficiency of sampling.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 As shown, a coal sampler includes a sampling cylinder 1, a rotating plate 2 rotatably connected to the sampling cylinder 1, a connecting block 8 fixedly connected to the sampling cylinder 1, a sampling structure 4 provided on the connecting block 8, a blocking structure 3 provided on the connecting block 8, the blocking structure 3 including a plurality of guide posts 302, a plurality of guide posts 302 threadedly connected to the connecting block 8, a common retaining ring 301 slidably connected to the plurality of guide posts 302, and a hook plate 304 rotatably connected to the connecting block 8.
[0021] As a technical optimization of this utility model, a return spring 303 is sleeved on the outside of the guide post 302. One end of the return spring 303 abuts against the connecting block 8, and the other end of the return spring 303 abuts against the retaining ring 301. The multiple guide posts 302 are arranged in a circular array about the center of the retaining ring 301. One end of the cross section of the guide post 302 has a T-shaped structure, one end of the cross section of the retaining ring 301 has a trumpet shape, and one end of the cross section of the hook plate 304 has an L-shaped structure. Therefore, the retaining ring 301 can block the rotating plate 2 under the action of the return spring 303.
[0022] As a technical optimization of this utility model, two handles 7 are fixedly connected to the connecting block 8, and a protrusion 6 is fixedly connected to the rotating plate 2, so that the rotating plate 2 can be easily rotated by holding the protrusion 6.
[0023] As a technical optimization of this utility model, the sampling structure 4 includes a spiral rod 402, which is rotatably connected to the connecting block 8. One end of the spiral rod 402 is fixedly connected to a crank handle 401, which has a Z-shaped structure. One end of the cross-section of the sampling cylinder 1 is inclined, so that the coal powder can be moved from the end of the sampling cylinder 1 to the inside of the collection bucket 501 by rotating the crank handle 401, thereby realizing the sampling of coal powder.
[0024] As a technical optimization of this utility model, the sampling cylinder 1 is provided with a collection structure 5, the collection structure 5 includes a collection bucket 501, the sampling cylinder 1 is threadedly connected to the collection bucket 501, the bottom end of the collection bucket 501 is threadedly connected to a baffle 502, and a transparent plate 503 is fixedly connected to one side of the collection bucket 501. Therefore, the coal powder after sampling can be collected through the collection bucket 501.
[0025] When using this invention, to sample coal, first hold both handles 7 and insert the sampling cylinder 1 into the coal pile. Since one end of the sampling cylinder 1 is inclined, insertion is easier. Then, turn the crank 401, which drives the screw rod 402 to rotate. Under the action of the screw rod 402, coal dust in the coal pile enters the collection bucket 501 for collection. A transparent plate 503 on one side of the collection bucket 501 allows for easy observation of the sample amount. Once the collection bucket 501 is full of coal dust, stop turning the crank 401 and pull the sampling cylinder 1 out of the coal pile, thus completing one coal dust sampling. Since coal dust remains inside the sampling cylinder 1 after sampling, pull the retaining ring 301. The retaining ring 301 slides on multiple guide posts 302, causing multiple return springs 303 to retract, continuously pushing the retaining ring 301 until one side of the retaining ring 301 is inside the hook plate 304. When the retaining ring 301 is released, because the end of the hook plate 304 has an L-shaped structure, the multiple return springs 303 will not extend and drive the retaining ring 301 to return to its original position under the action of the hook plate 304. At this time, the retaining ring 301 will not block the rotating plate 2, so the rotating plate 2 can be rotated. After the rotating plate 2 rotates, it will not block the remaining coal powder inside the sampling cylinder 1, thus facilitating the quick removal of the remaining coal powder inside the sampling cylinder 1 and avoiding affecting the next sampling. At the same time, after the rotating plate 2 rotates, it will not block the screw rod 402, which makes it easy to clean the screw rod 402, thus avoiding a large amount of coal powder adhering to the screw rod 402 and ensuring the sampling efficiency. When it is necessary to remove the coal powder inside the collection bucket 501, the baffle 502 can be rotated. When the baffle 502 is twisted off from the collection bucket 501, the coal powder inside the collection bucket 501 can be quickly removed. At the same time, twisting off the baffle 502 also makes it easy to clean the inside of the collection bucket 501.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
