Adjustable reduction device

Abstract

The invention provides an adjustable reduction device which comprises a rack, wherein a vertical partition plate is arranged inside the rack; the rack is divided into a plurality of cutting grooves; an adjustable reduction mechanism is connected with the upper part of the partition plate; the adjustable reduction mechanism comprises an adjusting plate and a connecting rod mechanism; the adjusting plate is hinged with the upper part of the partition plate through a rotating shaft arranged at a lower part; the connecting rod mechanism is positioned on the outer side of the rack; one end of the connecting rod mechanism is connected with one end of the rotating shaft; the adjusting plate can be driven to rotate for a preset angle when the connecting rod mechanism is rotated. By virtue of the adjustable reduction mechanism, the adjustable reduction device is capable of adjusting a reduction ratio according to demands, the reduction ratio can be adjusted within 1 / 2-1 / 32, requirements can be matched without a plurality of reduction devices, the reduction efficiency is improved, the reduction ratio can be adjusted randomly, automatic operation can be easily achieved, and moreover the cost can be lowered.

Description

technical field [0001] The invention relates to the field of shrinking and dividing devices, in particular to an adjustable shrinking and dividing device. Background technique [0002] At present, coal, iron ore and other mineral products industries conduct 1 / 2-1 / 32 reduction analysis of samples, usually using a splitter with a reduction ratio of 1 / 2. However, such an operation has high labor intensity, low efficiency, and small reduction ratio, and the reduction ratio cannot be adjusted according to needs, which is not conducive to realizing automatic operation. Contents of the invention [0003] Based on this, it is necessary to provide an adjustable shrinkage device with adjustable shrinkage ratio and high efficiency. [0004] An adjustable shrinking device, including a frame, the upper part of the frame is divided into a plurality of cutting grooves through a vertical partition, and an adjustable shrinking mechanism is connected to the upper part of the partition, and...
