Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Example 1

The utility model provides a mineral sampling device, includes ore bucket 1, ore bucket 1 upper end is feed inlet 2, and the lower extreme is discharge gate 3, is provided with feed divider 4 and intercommunication feed divider 4 outwards extends chute 5 in ore bucket 1 side for the discharge of mineral sample. The screening assembly comprises two groups of rotating wheels 6, the two groups of rotating wheels 6 are respectively arranged at two ends of the bucket 1, the two groups of rotating wheels 6 are connected through chains 7, the chains 7 are arranged at two ends of the rotating wheels 6, spacing bars 8 are arranged between the two groups of chains 7, mineral aggregate sorting is carried out by utilizing the spacing of the spacing bars 8, mineral aggregate larger than the spacing can stay on the spacing bars 8, mineral aggregate, broken slag and the like smaller than the spacing of the spacing bars 8 can fall from the spacing positions and fall to a discharge port 3 for the next procedure. The rotating wheel 6 is driven by a first driving motor 10, the output end of the first driving motor 10 is connected to the rotating wheel 6, and a conveying surface formed by the driving chain 7 and the separating rod 8 conveys mineral aggregate staying on the separating rod 8 to the distributing opening 4 to finish sampling.

Utilize screening function of separating rod 8 to select granule, disintegrating slag and dust etc. in the mineral aggregate to discharge gate 3, transport the mineral aggregate that remains on the separating rod 8 to the sample connection through first driving motor 10, avoid taking a large amount of residues in the sample for inconvenient follow-up sample detects, needs the secondary to select.

Too large minerals can stay on the separating rod 8, but the minerals cannot pass through the separating opening 4, and the too large minerals are not needed to be detected in sample detection, so a primary selection assembly is arranged above the screening assembly in the ore bucket 1 for separating the too large minerals.

The primary separation assembly comprises two groups of separation rods 9, the separation rods 9 are horizontally arranged, the arrangement direction is staggered with the direction of the separation rods 8, and two ends of the separation rods 9 are rotatably connected to the inner walls of the ore hoppers 1 above the two groups of rotating wheels 6.
