In the related technology, the width (the size in the front-back direction) of the belt stopping sampling frame is not adjustable, and one set of belt stopping sampling frame can only be suitable for sampling the material flow on the belt within the same width range. For example, when the width of the belt-off sampling frame is too small or the radian of the belt-off sampling frame does not match with the radian of the belt, the edge plate of the belt-off sampling frame cannot be used to intercept the material flow in a complete cross section on the belt as a sub-sample, so that the representativeness of the belt-off sampling cannot be ensured, and even the bias test period is delayed.

Since the first side plate connecting part 21 is detachably and adjustably connected to the first frame connecting part 111 and the second side plate connecting part 31 is detachably and adjustably connected to the second frame connecting part 121, the widths of the first side plate assembly and the second side plate assembly can be matched with the width of the belt 200 by increasing or decreasing the number of the first side plate 2 and the second side plate 3, so that the belt-stopping sampling frame 100 can adapt to belts 200 with different widths; the first abutting parts 22 can be abutted and matched with corresponding positions of the belt 200 by adjusting the relative positions of the first side plate connecting parts 21 and the first frame body connecting parts 111, and the second abutting parts 32 can be abutted and matched with corresponding positions of the belt 200 by adjusting the relative positions of the second side plate connecting parts 31 and the second frame body connecting parts 121, so that the belt-stopping sampling frame 100 can adapt to the belts 200 with different radians. Further, the belt-stopping sampling frame 100 provided by the embodiment of the invention can be adapted to sampling of material flows on the belts 200 with different widths and different radians, so that the representativeness of belt-stopping sampling is ensured, and the bias test can be completed on schedule.

In some embodiments, the first beam 11 is provided with a first slot 112, the second beam 12 is provided with a second slot 122, each of the first slot 112 and the second slot 122 extends in a front-back direction, the plurality of first side plates 2 are inserted into the first slot 112, and the plurality of second side plates 3 are inserted into the second slot 122.
Therefore, the left and right positions of the first side plates 2 can be limited by the two side walls of the first slots 112, which are oppositely arranged in the left and right directions, so that the first side plates 2 are aligned in the left and right directions, the formed first side plate assembly is relatively flat and has no large gap, and the phenomenon that the representativeness of the subsample is influenced because the subsample to be collected on the belt flows out of the first side plate assembly is effectively avoided; the position of the left and right directions of the second side plate 3 can be limited by the two groove side walls of the second slot 122 which are relatively arranged in the left and right directions, so that the second side plate 3 is aligned in the left and right directions, the formed second side plate assembly is smooth and has no large gap, and the problem that the sub-sample to be collected on the belt flows out from the second side plate assembly to influence the representativeness of the sub-sample is effectively avoided. Therefore, the insertion of the first plurality of side plates 2 into the first slots 112 and the insertion of the second plurality of side plates 3 into the second slots 122 are advantageous to improve the sampling representativeness of the tape stop sampling frame 100.
As will be appreciated by those skilled in the art: the distance between the two slot side walls of the first slot 112 oppositely disposed in the left-right direction should be slightly larger than the thickness of the first side plate 2 in the left-right direction, so that the first side plate 2 can move in the front-rear direction; accordingly, the distance between the two slot side walls of the second slot 122, which are oppositely disposed in the left-right direction, should be slightly larger than the thickness of the second side panel 3 in the left-right direction, so that the second side panel 3 can move in the front-rear direction.
It should be noted that, when the first side plate connection hole is a third elongated hole, the second side plate connection hole is a fourth elongated hole, the first side plate 2 is connected to the frame body 1 through the fastener, and the second side plate 3 is connected to the frame body 1 through the fastener, the first beam body 11 and the second beam body 12 may be slightly deformed when receiving a certain force in order to stably position the first side plate 2 on the first beam body 11 and the second side plate 3 on the second beam body 12 in the up-down direction. For example, when the fastening member is a bolt and the bolt on the first beam 11 is tightened, the two side walls of the first beam 11, which are oppositely disposed in the left-right direction, are slightly deformed by the pressing action of the nut of the bolt and the nut engaged with the bolt, so that the first side plate 2 is stably clamped between the two side walls of the first beam 11, which are oppositely disposed in the left-right direction; when the bolts on the second beam 12 are tightened, the two side walls of the second beam 12, which are oppositely arranged in the left-right direction, are slightly deformed by the pressing action of the nuts of the bolts and the nuts engaged with the bolts, so that the second side plate 3 is stably clamped between the two side walls of the second beam 12, which are oppositely arranged in the left-right direction.
