[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0027] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0028] The present utility model will be further described below in conjunction with specific embodiments, but it is not limited to the present utility model.

[0029] Embodiment 1

[0030] A sampling system with a circulating feeding track provided in this embodiment includes a stationary track 21, a sampling trolley 23, a sample discharging point 26, and at least one feeding trolley 25; the stationary track 21 is in a "U" shape and is installed on a steel structure 22; a moving track 24 is installed on the sampling trolley 23; the feeding trolley 25 is installed on a closed track, and the feeding trolley 25 can travel along the closed track.

[0031] In the present utility model, a ring-shaped closed track can be formed by enclosing between the moving track 24 and the stationary track 21, and a plurality of feeding trolleys 25 can be arranged on the above-mentioned ring-shaped closed track to transport the coal samples collected at multiple sampling points respectively. Further, to prevent the feeding trolleys 25 from colliding with each other in opposite directions, the plurality of feeding trolleys 25 can travel unidirectionally on the ring-shaped closed track in a clockwise / counterclockwise direction.

[0032] As a specific example, such as Figures 2 to 4As shown in the figure, the moving track 24 in the present utility model includes a transverse track 27 and two connecting tracks 28. The transverse track 27 is installed on the sampling cart 23 through a bracket 29. The connecting tracks 28 are respectively located at both ends of the transverse track 27. One end of the connecting track 28 is connected to one end of the transverse track 27, and the other end of the connecting track 28 away from the transverse track 27 extends above the stationary track 21. Under the above structure, the transverse track 27 and the two connecting tracks 28 are connected to form a "U"-shaped moving track 24, which encloses a circular closed track with the stationary track 21. Under such a track structure, when the sampling cart 23 travels along the independent track and approaches the coal transportation vehicle, the sampling device in the sampling trolley on the sampling cart 23 samples and sends the coal sample into the feeding trolley 25. Subsequently, the feeding trolley 25 drives into the stationary track 21 along the transverse track 27 and the connecting track 28, and then walks along the stationary track 21 to above the sample discharging point 26, and then puts the coal sample into the sample discharging point 26, and so on in a cycle. Under the above structure, only the sampling cart 23 and the sampling trolley on it need to travel a small distance, and the sampling device does not need to continuously travel back and forth between the sampling points in the carriage and the fixed sample discharging point for sampling and sample discharging operations, so the time consumed is short and the sampling efficiency is high.

[0033] Based on the above solution, as Figure 4 shown, to ensure that the feeding trolley 25 can drive onto or off the moving track 24 smoothly, in the present utility model, the other end of the connecting track 28 away from the transverse track 27 bends towards the direction close to the stationary track 21 and then extends and fits above the stationary track 21 to form a small-angle slope for the feeding trolley 25 to drive.

[0034] In the present utility model, the feeding trolley 25 can be of a cabin structure, with a feeding port opened at the top and a discharging gate installed at the bottom in an openable manner; during sampling, the coal sample is sent into the feeding trolley 25 through the feeding port, and when the feeding trolley 25 travels above the sample discharging point 26, the discharging gate is opened to discharge the coal sample into the sample discharging point 26.

[0035] In the present utility model, a sampling trolley is installed on the sampling cart 23. The sampling trolley can reciprocate along the trolley track on the sampling cart 23, and a sampling device is installed on the sampling trolley; the above structure can directly adopt the relevant structures in the existing technology, so it will not be elaborated in this application.

[0036] In the present utility model, the sample discharging point 26 is located at a corner of the closed track away from the transverse track 27 to avoid interfering with other structures as much as possible.

[0037] Embodiment 2

[0038] The sampling system provided in this embodiment is basically the same as that in Embodiment 1, except that guide wheels 210 are installed on both sides of the connecting track 28 opposite to the stationary track 21, and the guide wheels 210 are in rolling connection with the stationary track 21; the above-mentioned guide wheels 210 can ensure that the moving track 24 is aligned with the stationary track 21, preventing accidents such as the feeding trolley 25 hitting the track or derailing due to track misalignment.

[0039] Embodiment 3

[0040] The sampling system provided in this embodiment is basically the same as that in Embodiment 1, except that a bottom wheel 211 is installed at the bottom of one end of the connecting track 28 close to the transverse track 27, and the bottom wheel 211 is in rolling connection with the stationary track 21; under the above structure, the anti-deviation guiding of the moving track 24 is realized through the rim of the bottom wheel 211; at the same time, the moving track 24 moves on the stationary track 21 through the bottom wheel 211, which can change the sliding friction that may occur when the two are directly in contact during movement into rolling friction, reduce the friction force, and reduce the wear on the track.

[0041] It should be noted that the bottom wheel 211 in this embodiment can also be used in cooperation with the guide wheel 210 in Embodiment 2.

[0042] The above are only preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be able to realize that any equivalent replacement and obvious changes made by using the content of the specification of the present invention should be included in the protection scope of the present invention.
