[0002] At present, most belt sampling machines are in a fixed form. The cutter cuts a complete oblique cross section of the material flow along a plane perpendicular to the center line of the belt above the belt. Due to the movement of the belt, the cross section is aligned with the center line of the belt. At certain angles, the sampling process is an oblique cut rather than the ideal vertical cut
At the same time, the side plate of the cutter blocks the material flow, and the material accumulates and overflows the belt.
The general trough idler is composed of a slanted roller on the left and a horizontal roller on the bottom. The three-section roller supports the upper belt to form a trough shape. The trough shape is formed by three sections of broken lines plus two transition arcs. The cutter The circular arc working trajectory does not coincide with the broken line trough profile, especially the sampling blind area is formed at the transitional arc, and a complete material flow cross-section in the true sense cannot be taken, and it is impossible for the cutter to cut the oblique cross-section due to the limited volume. All the materials in the section are collected

Embodiment Construction
[0013] exist figure 1 Among them, the main belt conveyor (5) is divided into normal section, shaping section, sampling section, recovery section and normal section from left to right. The standard troughed idler (1) on the left and the standard troughed idler (1) on the left and right are the normal section; the standard troughed idler (1) and several semicircular arc idlers (2) constitute It is the shaping section, and the groove radii of the semicircle-arc rollers (2) in the shaping section are different, and gradually become smaller from the normal section to the shaping section, and gradually become larger from the shaping section to the normal section; The roller (2) constitutes a sampling section, and the groove radii of the semicircular arc supporting rollers (2) in the sampling section are the same. The sampling trolley (3) straddles the main belt conveyor (5), and can walk along the conveying direction of the main belt conveyor (5) in the shaping section, the samplin...

The invention relates to a reciprocating shuttle synchronous belt sampler which is arranged on a belt conveyor, moves with the belt conveyor simultaneously and cuts a complete material flow cross section. A standard grooved carrier roller of an original main belt conveyor sampling section is detached and replaced by a plurality of semicircle carrier rollers formed by a plurality of rollers; a sampling cart provided with a rotatable cutter can reciprocate along the conveying direction of a main belt and keeps moving simultaneously with the main belt conveyor in the sample section, and meanwhile,, one sampling is finished after the rotatable cutter rotates a circle. The invention realizes vertical cutting sampling to movable belts and adopts the true and complete material flow cross section without sampling blind areas.
Description
Technical field [0001] The invention relates to the technical field of belt sampling, in particular to a reciprocating shuttle synchronous belt sampling machine which moves synchronously with the belt conveyor on the belt conveyor and cuts a complete material flow cross section perpendicular to the belt conveying direction. Background technique [0002] At present, most belt sampling machines are in a fixed form. The cutter cuts a complete oblique cross section of the material flow along a plane perpendicular to the center line of the belt above the belt. Due to the movement of the belt, the cross section is aligned with the center line of the belt. At a certain angle, the sampling process is an oblique cut rather than an ideal vertical cut. At the same time, the side plate of the cutter blocks the material flow, and the material accumulates and overflows the belt. The general trough idler is composed of one inclined roller on the left and one horizontal roller on the botto...
