Embodiment 1

[0028] (1) Place the naturally dried soil sample on the feed hopper 4, and tap a large soil block with a rubber hammer. At this time, the mesh baffle plate 3 will block impurities such as plant roots, solid waste and stones in the sample. In the feed hopper 4, fine particles enter the integrated machine.

[0029] (2) Insert the 10-mesh screen 9, replace the corresponding coupling 13 according to the required soil particle size, turn on the servo motor 2 and control the running speed, and start grinding.

[0030] (3) After grinding, take out the sample collection box 10, check whether the ground soil sample meets the requirement of 2 mm, if it is qualified, pack it into a bag for the next step of experimental data determination; if the amount of ground sample does not meet the experimental requirements, Then repeat the above procedure for secondary grinding.

Embodiment 2

[0032] (1) Place the naturally dried soil sample on the feed hopper 4, and tap a large soil block with a rubber hammer. At this time, the mesh baffle plate 3 will block impurities such as plant roots, solid waste and stones in the sample. In the feed hopper 4, fine particles enter the integrated machine.

[0033] (2) Insert the 100-mesh screen 9, change the length of the corresponding coupling 13 according to the required soil particle size, turn on the servo motor 2 and control the running speed, and start grinding.

[0034] (3) After grinding, take out the sample and collect 10, check whether the ground soil sample meets the requirement of 0.15mm, if it is qualified, pack it into a bag for the next step of experimental data determination; if the amount of ground sample does not meet the experimental requirements, Then repeat the above procedure for secondary grinding.

Abstract

The invention relates to the technical field of soil sample screening-grinding equipment, particularly to a soil analysis sample screening-grinding movable all-in-one machine for laboratory analysis. The technical scheme of the machine is that the movable all-in-one machine includes a machine body, a feeding treatment system, a grinding system and a classified screening system, wherein the machine body is formed by a cuboid box body; a feeding treatment system is arranged at the upper part of the side wall of the box body; the classified screening system is positioned at the middle lower part of the box body; the grinding system is positioned at the middle upper part of the box body and is arranged in the middle part. Tests show that the all-in-one machine can one-step pulverize soil into particles not larger than 2 mm in diameter and counting for 85% above, and one-step pulverize soil into particles not larger than 0.15 mm in diameter and counting for 65% above, and the screening yield is 100%. The machine has the advantages that the obtained materials are common, the operation is simple, high quality and efficiency are realized, no pollution to a soil sample is caused, and the result is reliable.

Description

technical field [0001] The invention relates to a soil analysis sample screening-grinding movable all-in-one machine. Background technique [0002] Grinding and crushing of soil samples is the basic link in the analysis of related indicators such as soil nutrients and components in the laboratory. Different nutrient determination and component analysis have different requirements for the particle size of soil samples, and the most commonly used ones are 0.15mm and 2mm. This requires different grinding equipment and screens. [0003] At present, the grinding and crushing of soil samples mainly include manual grinding and machine crushing, each with its own advantages and disadvantages. [0004] There are mainly two types of manual grinding devices: medicine grinding mortar and push-type grinding disc. The advantage is that the particle size of soil samples can be manually controlled according to the experimental requirements, and the plant roots, solid waste, Impurities su...
