Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and in particular to a pretreatment device for soil testing. Background Technology

[0002] In the field of soil composition analysis, sample pretreatment is a crucial step affecting data accuracy. Traditional soil grinding devices often suffer from the following problems: separation of grinding and sieving: after grinding, samples must be manually transferred to an independent sieve device, which can easily lead to secondary agglomeration of soil clumps or cross-contamination; difficult sieve maintenance: fixed filter screens are difficult to disassemble and clean, and residual particles can clog the mesh, reducing sieving efficiency; low automation: tilting the grinding container relies on manual operation, making it impossible to accurately control the feeding angle and speed, affecting the uniformity of subsequent filtration. To address these issues, we propose a pretreatment device for soil analysis. Utility Model Content

[0010] Beneficial effects This invention provides a pretreatment device for soil testing. It has the following beneficial effects: (1) In this soil testing pretreatment device, a rotary motor drives a "C"-shaped connecting rod to rotate an inclined grinding rod, the tilt angle of which enhances the shearing force on the clumped soil; at the same time, the grinding box is controlled by a servo motor to rotate, forming a compound motion with the grinding rod, accelerating the uniformity of crushing; the telescopic device retracts to pull the locking block and the storage box to move downwards; the servo motor drives the grinding box to flip and pour the soil into the storage box; the soil falls directly into the detachable filter screen, qualified particles enter the bottom cavity of the storage box, and large particles remain on the screen surface. The flip angle of the grinding box and the downward distance of the storage box are precisely matched to ensure that the soil falls accurately into the filtration area, avoiding errors caused by manual transfer and realizing full-process automation.

[0011] (2) In this soil testing pretreatment device, the filter screen is fixed to the second connecting block through the third connecting block, and the second connecting block is connected to the slider through the first connecting block; by moving the slider upward along the slide groove, the filter screen can be moved out of the storage box for cleaning or replacement; the connecting cylinder at the bottom of the storage box has a torsion spring driven rotating column and a squeezing block inside; when the telescopic device pushes the card block into the connecting cylinder, the squeezing block is pressed against the side of the card block by the torsion spring, forming a self-locking fixation, ensuring that the storage box does not shift during grinding.
