Description

Technical Field

[0001] This utility model relates to the field of coal mine sampling technology, and more specifically, to a full-section sampling tool for coal flow systems. Background Technology

[0002] Full-section sampling of the coal flow system is a crucial step in coal quality testing. Traditional sampling methods rely on manual sampling of coal from a stopped conveyor belt, which has significant drawbacks: Power outage registration is required before sampling (taking an average of 30-60 minutes per instance), severely restricting continuous production; manual sampling is limited to the edge of the conveyor (coverage <40%), making it difficult to obtain representative samples from the entire cross-section, resulting in deviations of 15%-20% for key indicators such as ash and sulfur content. More seriously, the risk of personnel's sleeves and tools being caught in the transmission mechanism while working near the operating conveyor belt is as high as 0.3 times per thousand samples, violating Article 378 of the "Coal Mine Safety Regulations" regarding protective measures for working near dynamic equipment, and urgently needs improvement.

[0003] In summary, how to provide a full-section sampling tool for coal flow systems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A full-section sampling tool for a coal flow system includes a support column. The bottom end of the support column is equipped with an adjustment mechanism that drives the support column to move back and forth and up and down. The outer end of the support column is equipped with an automatic sampling mechanism. The outer end of the sampling mechanism is equipped with a sealing mechanism that seals the guide end of the sampling mechanism. The front of the support column is equipped with a positioning mechanism for quickly snapping on a sampling bag. The top of the sampling mechanism is equipped with a feeding mechanism.

[0007] On the other hand, the sampling mechanism includes a U-shaped fixing plate and a U-shaped fixing block. The U-shaped fixing plate is installed on the upper surface of the support column. Through holes are opened on the inner walls of both sides of the U-shaped fixing plate. Rotating rods are rotatably connected inside the two sets of through holes of the U-shaped fixing plate. A sampling sleeve is installed between the two sets of rotating rods. The U-shaped fixing block is installed on the front of the support column.

A hydraulic cylinder is installed on the upper surface of the connecting block. The output end of the hydraulic cylinder is installed on the outer surface of the sampling sleeve.

[0008] On the other hand, the adjustment mechanism includes a base placed on the ground. The upper surface of the base has a slot, and the inner walls of the front and rear sides of the slot have grooves. Threaded rods are rotatably connected inside the two sets of grooves of the base. A first motor is installed on the front of the base, and the output shaft of the first motor is installed at the front end of the threaded rod. A sliding plate is threaded to the outside of the threaded rod, and a first electric telescopic rod is installed at the top of the sliding plate. A support column is installed at the output end of the first electric telescopic rod.

[0009] On the other hand, the sealing mechanism includes a first arc-shaped fixing block, which is installed on the outer surface of the sampling sleeve. A second electric telescopic rod is installed on the front side of the first arc-shaped fixing block, and a second arc-shaped fixing block is installed at the output end of the second electric telescopic rod.

[0010] On the other hand, the positioning mechanism includes a positioning plate, which is installed on the front of the support column. A groove is provided on the upper surface of the positioning plate, and a positioning frame is engaged inside the groove of the positioning plate. The position of the groove inside the positioning plate is located at the lower end of the rotation path of the sampling sleeve guide end.

[0011] On the other hand, the feeding mechanism includes a U-shaped fixing frame, which is installed on the upper surface of the U-shaped fixing plate.

Detailed Implementation

[0022] 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 scope of protection of the present utility model.

[0023] The core of this utility model is to provide a full-section sampling tool for coal flow systems, and to combine it with... Figures 1-4 The components of this tool will be described in detail below:

[0024] like Figure 1 As shown, the full-section sampling tool for the coal flow system includes a support column 2. An adjustment mechanism 1 is installed at the bottom of the support column 2 to drive its forward, backward, up, and down movement. An automatic sampling mechanism 3 is installed at the outer end of the support column 2. A sealing mechanism 4 is installed at the outer end of the sampling mechanism 3 to seal its guide end. A positioning mechanism 6 for quickly engaging the sampling bag is installed on the front of the support column 2. A feeding mechanism 5 is installed at the top of the sampling mechanism 3. Specifically, by activating the sampling mechanism 3, the sampling end of the sampling mechanism 3 is inserted into the interior of the coal mine at the upper end of the conveyor belt. Then, by activating the sampling mechanism... The repositioning of sampling mechanism 3 guides the coal accumulated inside the sampling mechanism 3 into the sampling bag, enabling the sampling mechanism 3 to automatically collect coal from the upper end of the conveyor belt during startup. This allows the sampling mechanism 3 to replace manual labor in collecting coal samples from a stopped conveyor belt, simplifying the sampling process. It eliminates the need for power outage registration procedures for the conveyor belt and ensures timely, safe, and reliable sampling across the entire cross-section of the coal flow. This reduces the labor intensity of the sampling process and improves the efficiency of sampling and testing, thus enhancing the practicality of the device.

[0025] like Figures 2-4As shown: The sampling mechanism 3 includes a U-shaped fixing plate 302 and a U-shaped fixing block 305. The U-shaped fixing plate 302 is installed on the upper surface of the support column 2. Through holes are opened on the inner walls of both sides of the U-shaped fixing plate 302. Rotating rods 303 are rotatably connected inside the two sets of through holes of the U-shaped fixing plate 302. A sampling sleeve 301 is installed between the two sets of rotating rods 303. The U-shaped fixing block 305 is installed on the front of the support column 2. Through holes are opened on the inner walls of both sides of the U-shaped fixing block 305. Connecting blocks 304 are rotatably connected inside the two sets of through holes of the U-shaped fixing block 305. A hydraulic cylinder 306 is installed on the upper surface of the connecting block 304. The output end of the hydraulic cylinder 306 is installed on the outer surface of the sampling sleeve 301.

[0026] Specifically, by pushing the support column 2, the sampling end of the sampling mechanism 3 is adjusted and moved to the top of the coal mine on the upper end of the coal conveyor belt. Then, by starting the hydraulic cylinder 306, the sampling port at the rear end of the sampling sleeve 301 is rotated, inserting the sampling port of the sampling sleeve 301 into the inside of the coal mine on the upper end of the coal conveyor belt. By starting the hydraulic cylinder 306, the sampling sleeve 301 is reset, allowing the coal inside the sampling sleeve 301 to be discharged into the sampling bag along the internal channel. This allows the sampling mechanism 3 to replace manual labor in taking coal samples on a stopped conveyor belt. This simplifies the sampling process, eliminates the need for power outage registration for the conveyor belt, and ensures timely, safe, and reliable sampling of the entire cross-section of the coal flow. This reduces the labor intensity of the sampling process and improves the efficiency of sampling and testing, thus enhancing the practicality of the device.

[0027] The adjustment mechanism 1 includes a base 101, which is placed on the ground. A slot is provided on the upper surface of the base 101. Grooves are provided on the inner walls of the front and rear sides of the slot of the base 101. A threaded rod 104 is rotatably connected inside the two sets of grooves of the base 101. A first motor 105 is installed on the front side of the base 101. The output shaft of the first motor 105 is installed at the front end of the threaded rod 104. A sliding plate 103 is threadedly connected to the outside of the threaded rod 104. A first electric telescopic rod 102 is installed at the top of the sliding plate 103. A support column 2 is installed at the output end of the first electric telescopic rod 102.

[0028] Specifically, by starting the first motor 105, the threaded rod 104 triggers the sliding plate 103 to slide back and forth on the upper end of the base 101. Then, by starting the first electric telescopic rod 102, the support column 2 is pushed up and down on the upper end of the base 101. This allows the support column 2 and the sampling mechanism 3 to move back and forth and up and down during use, enabling the sampling mechanism 3 to sample coal from the upper end of various coal mine conveyor belts, thus expanding the applicability of the device. When the inlet of the sampling sleeve 301 comes into contact with the coal at the upper end of the coal mine conveyor belt, the adjusting mechanism 1 is started to push the inlet of the sampling sleeve 301 deeper into the conveyed coal mine. This allows the sampling sleeve 301 to collect more coal in a single sampling process, thereby reducing the time spent by the subsequent sampling mechanism 3 during the sampling process.

[0029] The sealing mechanism 4 includes a first arc-shaped fixing block 401, which is installed on the outer surface of the sampling sleeve 301. A second electric telescopic rod 402 is installed on the front of the first arc-shaped fixing block 401, and a second arc-shaped fixing block 403 is installed at the output end of the second electric telescopic rod 402. A protective cover plate 404 is installed on the lower surface of the second arc-shaped fixing block 403, and the back of the protective cover plate 404 abuts against the feed inlet of the sampling sleeve 301. Specifically, when the sampling sleeve 301 is sampling, the second electric telescopic rod 402 is activated to pull the second arc-shaped fixing block 403, thereby moving the protective cover plate 404 to abut against the outer end of the feed inlet of the sampling sleeve 301. This allows the sealing mechanism 4 to seal the feed inlet of the sampling sleeve 301, thereby minimizing the spillage of the sampled coal accumulated inside the sampling sleeve 301 during rotation.

[0030] The positioning mechanism 6 includes a positioning plate 601, which is installed on the front of the support column 2. A groove is formed on the upper surface of the positioning plate 601, and a positioning frame 602 is engaged inside the groove of the positioning plate 601. The position of the groove inside the positioning plate 601 is located at the lower end of the rotation path of the guide end of the sampling sleeve 301. Specifically, when the sampling bag is sleeved into the groove of the positioning plate 601, the positioning frame 602 is pushed to engage with the groove of the positioning plate 601 and the inside of the sampling bag, so that the positioning mechanism 6 restricts the movement of the sampling bag during use. By using the snap-fit ​​method to install the sampling bag inside the positioning mechanism 6, the sampling bag can be quickly installed and removed, thereby reducing the time spent by the staff in the process of installing and removing the sampling bag.

[0031] The feeding mechanism 5 includes a U-shaped fixing frame 501, which is installed on the upper surface of the U-shaped fixing plate 302. A second motor 502 is installed on the top of the inner wall of the U-shaped fixing frame 501. A connecting rod 503 is installed on the output shaft of the second motor 502. Two sets of flexible plates 504 are installed on the outer surface of the connecting rod 503. The sampling sleeve 301 is located on the rotation path of the two sets of flexible plates 504. Specifically, by starting the second motor 502, the two sets of flexible plates 504 are driven to rotate. Since the sampling sleeve 301 is located on the rotation path of the two sets of flexible plates 504, the two sets of flexible plates 504 tap the sampling sleeve 301 during rotation, thereby accelerating the feeding speed of the feeding end of the sampling sleeve 301. This reduces the time consumed by the sampling mechanism 3 during use, thus improving the practicality of the device.

[0032] The top of the sampling sleeve 301 has a groove, and an acrylic plate 7 is installed inside the groove of the sampling sleeve 301. Specifically, the acrylic plate 7 is made of transparent material, which allows the staff to see through the acrylic plate 7 whether there is any blockage inside the sampling sleeve 301. This makes it convenient for the staff to clean the inside of the sampling sleeve 301 in a timely manner, thereby avoiding data errors caused by prolonged use of the sampling sleeve 301 with blockage.

[0033] The upper surface of the support column 2 has two sets of grooves, and the two sets of grooves are slidably connected to the limiting rods 8. The bottom ends of the two sets of limiting rods 8 are installed on the upper surface of the slide plate 103. Specifically, by sliding the support column 2 to the outer ends of the two sets of limiting rods 8, the two sets of limiting rods 8 restrict the movement path of the support column 2, thereby minimizing the risk of the support column 2 shifting its position during adjustment and movement, which could cause the first electric telescopic rod 102 to bend. This improves the service life of the first electric telescopic rod 102.

[0034] In summary: By pushing the support column 2, the sampling end of the sampling mechanism 3 is adjusted and moved to the top of the coal mine on the upper end of the coal conveyor belt. Then, by starting the hydraulic cylinder 306, the sampling port at the rear end of the sampling sleeve 301 is rotated, and the sampling port of the sampling sleeve 301 is inserted into the inside of the coal mine on the upper end of the coal conveyor belt. By starting the hydraulic cylinder 306, the sampling sleeve 301 is reset, so that the coal inside the sampling sleeve 301 is discharged into the sampling bag along the internal channel. Thus, the sampling mechanism 3 can replace manual labor to take coal samples on the stopped conveyor belt. By starting the first motor 105, the threaded rod 104 triggers the sliding plate 103 to slide back and forth on the upper end of the base 101. Then, by starting the first electric telescopic rod 102, the support column 2 is pushed up and down on the upper end of the base 101. Thus, the support column 2 and the sampling mechanism 3 can move back and forth and up and down during use, so that the sampling mechanism 3 can sample coal from the upper end of various coal mine conveyor belts during use.

[0035] Simultaneously, by activating the second electric telescopic rod 402, the second arc-shaped fixing block 403 is pulled to move the protective cover plate 404, which then abuts against the outer end of the guide port of the sampling sleeve 301, thereby sealing the guide port of the sampling sleeve 301 with the sealing mechanism 4. By activating the second motor 502, the two sets of flexible plates 504 are rotated. Since the sampling sleeve 301 is located on the rotation path of the two sets of flexible plates 504, the two sets of flexible plates 504 beat the sampling sleeve 301 during rotation, thereby accelerating the feeding speed of the guide end of the sampling sleeve 301.
