[0003] When sampling coal, the moisture content of the coal from individual mining sites is too high, which easily causes coal accumulation and blockage at the feeding port and other parts of the vehicle sampling machine, making it inconvenient to transport through the feeding belt. When sampling a large amount of coal, frequent sampling failures easily lead to low sampling efficiency. At the same time, workers are required to carry out maintenance and cleaning, increasing the labor intensity. How to invent an anti-blocking structure for a sampling machine to improve these problems has become an urgent problem for those skilled in the art. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides an anti-blocking structure for a sampling machine, aiming to improve the problems that excessive coal moisture easily causes coal accumulation and blockage at the feeding port and other parts of the vehicle sampling machine, resulting in low sampling efficiency, and the need for workers to carry out maintenance and cleaning, increasing the labor intensity.

[0024] Please refer to Figure 1 and Figure 2 , the present utility model provides a technical solution: an anti-blocking structure for a sampling machine, including a sampling machine body 100 for sampling coal, and further including

[0025] The anti-blocking detection mechanism 200, the anti-blocking detection mechanism 200, the anti-blocking detection mechanism 200 includes an adjustment component 210 and a pressing-down component 220. The adjustment component 210 includes a slide rail 211 and a sliding ring 213. The slide rail 211 is installed on both sides of the sampler body 100. The sliding ring 213 is sleeved on the sampler body 100, and the sliding ring 213 is in limiting sliding connection with the slide rail 211. The anti-blocking detection mechanism 200 is limit-installed outside the adjustment component 210. A moisture measuring instrument 230 is installed at the bottom of the pressing-down component 220. The adjustment component 210 slides up and down on the sampler body 100, so that when the sampler body 100 penetrates into the coal, the adjustment component 210 is located above the coal to prevent the coal from accumulating on the adjustment component 210 and the pressing-down component 220. The pressing-down component 220 controls the position of the moisture measuring instrument 230, so that when it is necessary to detect the moisture in the coal, the pressing-down component 220 controls the moisture measuring instrument 230 to be located below the adjustment component 210, which is convenient for the moisture measuring instrument 230 to insert into the coal to measure the moisture of the coal and enable the sampler body 100 to take corresponding countermeasures in advance.

[0026] Please refer to Figures 2 to 4 , the adjustment component 210 further includes a limit block 215. The limit block 215 is fixedly installed on the inner wall of the sliding ring 213. The slide rail 211 is in limiting sliding connection with the limit block 215. The sliding ring 213 is sleeved outside the two slide rails 211 in a limiting sliding manner. Ropes 212 are respectively arranged inside the slide rails 211. One end of each rope 212 is connected to a reel. The other end of the rope 212 is in limiting connection with the sliding ring 213. One end of the rope 212 is connected to a reel, and the reel is used to drive the sliding ring 213 to rise and position. When a section of the rope 212 is released, the sliding ring 213 will slide down to be conveniently located above the coal pile. The reel can be replaced with other structures such as an electric hoist for winding and releasing the rope 212. Connecting blocks 214 are fixedly connected to both sides of the top of the sliding ring 213, and the connecting blocks 214 are fixedly connected to the ropes 212. The limit block 215 is arranged in an isosceles trapezoid shape. A chute matching the limit block 215 is opened on one side of the slide rail 211. The limit block 215 is arranged in an isosceles trapezoid shape, which is convenient for being stuck inside the slide rail 211 and also convenient for sliding up and down.

[0027] Please refer to Figure 3 and Figure 4, the pressing component 220 includes an installation ring 221 and a limit slider 222. There are two sets of installation rings 221. The two ends of the two sets of installation rings 221 are respectively fixedly connected with limit sliders 222. The limit sliders 222 are slidably connected to the sliding ring 213 in a limiting manner. Electric push rods 224 are respectively fixedly connected to the outer sides of the tops of the two sets of installation rings 221. The tops of the electric push rods 224 are respectively fixedly connected with positioning plates 223. The positioning plates 223 are respectively fixedly connected to the backs of the connecting blocks 214. The electric push rods 224 are used to drive the two sets of installation rings 221 to rise and fall respectively. The two sets of installation rings 221 are used to drive the moisture meter 230 up and down. The rising of the moisture meter 230 is used to prevent the bottom of the moisture meter 230 from being damaged. The lowering of the moisture meter 230 facilitates measurement. The two sets of installation rings 221 are both arc-shaped, and the two sets of installation rings 221 enclose a shape similar to a frustum of a cone. The side of the limit slider 222 close to the sliding ring 213 is an isosceles trapezoid, and a groove matching the limit slider 222 is provided on the outer wall of the sliding ring 213. There are four sets of moisture meters 230. The four sets of moisture meters 230 are respectively installed at both ends of the installation ring 221 directly below the limit slider 222. The four sets of moisture meters 230 are respectively electrically connected to the sampling machine body 100 through a single-chip microcomputer, etc. When the moisture monitored by the moisture meter 230 is greater than the set value, the sampling machine body 100 is controlled to make corresponding symmetrical reductions to reduce the risk of blockage.

[0028] Working principle: The sampling machine body 100 samples coal. When the sampling machine body 100 inserts into the coal pile, the sliding ring 213 is released in advance so that the sliding ring 213 is located at the lower end of the sampling machine body 100. At this time, the sampling machine body 100 descends to mine coal. While the sampling machine body 100 is working, the electric push rod 224 controls the installation ring 221 to descend, so that the installation ring 221 drives the moisture meter 230 to be located at the bottom of the sliding ring 213, so that the moisture meter 230 penetrates into the coal to detect the moisture content in the coal. If the moisture content in the coal is relatively high, it will transmit a signal to increase the rotation speed of the sampling machine body 100 and slow down the descending speed at the same time, preventing blockage caused by entering a large amount of coal with high moisture at one time.

[0029] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
