A multi-compartment shrink divider

Abstract

The present invention relates to a multi-separation groove reduction device, which comprises a box, baffles, a connection rod mechanism, a long connection rod, a horizontal movement mechanism, material receiving grooves, a material falling hopper and a drive mechanism, wherein the horizontal movement mechanism is connected with the box and is used for driving the box to drive, the box is arranged below the material falling hopper, the upper end of the box is the opening, more than three sequentially-aligned material distribution separation grooves are arranged inside the box, the material receiving grooves are arranged below the box, the number of the material receiving grooves is more, a plurality of the material receiving grooves are aligned along the direction perpendicular to the aligning direction of the material distribution separation grooves, the outlets are arranged below each material distribution separation groove, the directions of the outlets of each material distribution separation groove are not exactly the same, the outlets are respectively corresponding to the one material receiving groove, the baffle is arranged above the position above any two adjacent material distribution grooves, each baffle is rotatably arranged on the box through a rotation shaft, and the adjusting device is connected with the rotation shaft and is used for controlling the size of the opening between the any two adjacent baffles.

Description

technical field [0001] The invention relates to the technical field of shrinking and dividing, in particular to a multi-slot shrinking and dividing device. Background technique [0002] In the design of mechanized sample collection and preparation, the reducer is an instrument mainly used to complete the reduction of samples, and it is also the key equipment in the sample preparation system. The more times the reducer cuts the sample, the higher the reduction accuracy. [0003] Such as figure 1 with figure 2 As shown, currently the most widely used shrink divider mainly includes a blanking hopper 7, a box body 1, an adjustment rod 2, a rotating shaft 3, a baffle plate 4, an adjustment bracket 5, a material separation groove 6, a blanking hopper 7, and a horizontal movement mechanism 8 and receiving trough 9, the samples in the drop hopper 7 fall evenly from the lower outlet, and the shrinking device moves back and forth along the direction of the arrow under the action of...

Problems solved by technology

However, since this splitter can only adjust the opening of one distribution compartment when the splitter is splitting, when the sample volume is small, in order to meet the requirements of sample retention, it is necessary to increase the opening of the baffle, but because the drop hopper The opening is constant, so the time for the sample to enter the shrinker is short, and the speed of the shrinker is constant during reciprocating operation, which will result in fewer cuts of the sample. According to the requirements of GB474, the minimum cutting time for the shrinkage of the synthetic reserved sample The number of times is 60, and the existing shrinker does not meet the sample retention requirements when the sample volume is small
