Abstract
The utility model relates to a high division ratio screw drill sampler, which belongs to the technical field of weighing and sampling in transportation, and is mainly used to mechanically sample bulk material loaded on vehicles or vessels. The utility model is characterized in that: a plurality of helical blades are arranged on a main shaft with a spiral sampling drill, a positioning pipe is arranged on the periphery of the main shaft, and a distributing platform with a feed distributor is arranged on the top of the positioning pipe. The utility model has the advantages that: the division ratio can be chosen between one third and one twelfth, and the sample reservation quantity is greatly reduced, thus decreasing the load and costs of sampling at a lower level.
Description
Technical field
The utility model relates to the weighing Sampling techniques field of transportation aspect, is mainly used in vehicle-mounted (automobile, train) boat-carrying bulk material (as: coal, ore in sand form, ore) is realized the mechanical sampling process.
Technical background
The present spiral Sampling Machine of using, its division adopts 1/2 than mostly, and this division is than little, and the amount of keeping sample is many, brings many difficulties for next stage sample preparation work, and increases equipment investment.
Summary of the invention
The purpose of this utility model provides a kind of its division than the high-shrinkage proportion by subtraction spiral drill Sampling Machine that can reach 1/3-1/12.
The purpose of this utility model be achieved in that sample that the spiral sampling that is connected on the main shaft drills through by helical blade along sampling brill positioning pipe vertical transport to the cloth platform, distributing device is evenly distributed to the sample of cloth platform in n the grid (n=3-12), the material of getting in one of them grid is stored in the collection bucket as increment (1/n), material in all the other (n-1) individual grids by deadweight in elephant trunk falls go back to former compartment, thereby realization 1/n curtailed sampling.
The utility model has the advantages that: its feeding mouth can according to the amount of keeping sample what, be chosen the division ratio by the maximum particle size design of material.Its division ratio can be selected at 1/3-1/12, especially realizes 1/12 high-shrinkage proportion by subtraction, has significantly reduced the sample amount of keeping sample like this, thereby has reduced the load and the cost of next stage sample preparation.
Description of drawings
