Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0027] like figure 1 As shown, a solid material sampling machine of the present invention includes a central tube at the central position, a rotary feeding tube 10 that can rotate axially is sheathed on the outside of the central tube, and a gap is left between the rotary feeding tube 10 and the central tube Feeding cavity. The feeding cavity is mainly used as a channel for materials to be conveyed from bottom to top, and the axial rotation of the rotating feeding pipe 10 provides power for the materials to be conveyed upward. The outer upper part of the rotating feeding pipe 10 is covered with a sliding sleeve 2, and the sliding sleeve 2 is connected with the rotating feeding pipe 10 through a bearing 7 to form a concentric fitting that can rotate relatively and can withstand a certain axial pressure. The barrel 2 is provided with a power motor 8 that drives and co...

Abstract

A solid material sampling machine of the present invention comprises a central tube, a rotating feeding tube is sheathed outside the central tube, a feeding cavity is left between the rotating feeding tube and the central tube, and a feeding cavity is opened at the bottom of the rotating feeding tube. There is a discharge port on the top of the rotating feeding tube, an impact mechanism is installed at the lower part of the center tube, and an impact sampling head is driven and connected to the bottom of the impact mechanism. The lifting mechanism I is connected with a blocking block that can penetrate into the feeding through hole at the end of the descending stroke and block the feeding through hole. The beneficial effect of the invention is: it has the function of impact crushing and collection, and has the ability that the whole batch of materials may be collected and collected with equal chances. It can seal the feed through hole without leaking the bottom sample, and has the functions of full-section sampling and point sampling at any depth. The sampler can sample the bottom material without damaging the objects under the bottom material.

Description

technical field [0001] The invention relates to a solid material sampling machine. Background technique [0002] A typical ore and coal sampling machine adopts a screw-type sampler. Its structure is composed of a rotating screw rod in the middle and a stationary barrel tube on the outside. Downward pressure, under the action of the two, the sampler is inserted into the material for sampling, and the sample enters from the lower opening of the stationary barrel tube through the rotation of the helical blade of the screw rod. The disadvantages of this sampler are: (1) The sampler only has Pressure and rotational torque, hard block materials cannot be crushed, and the spiral groove is easy to be blocked. In case of large stones or large hard materials, the sampling head cannot be broken and inserted under the hard object, resulting in a dead angle under the hard object. Sampling, can only give up and find another sampling point. (2) The edge of the opening of the barrel tube ...
