Technical Field

[0001] The utility model belongs to the technical field of solution analysis and detection, in particular to an automatic stirring device for soil solution. Background Art

[0002] In the soil resource survey, it is generally necessary to stir the soil solution when doing mechanical composition determination. The purpose of stirring the soil mechanical composition is to mix the immiscible liquids in the soil evenly, prepare a uniform mixture or emulsion, and strengthen the mass transfer process. At the same time, stirring can also fully disperse the gas in the liquid, strengthen mass transfer or chemical reaction. In addition, stirring can also prepare a uniform suspension, accelerate the dissolution and leaching of solids, or cause liquid-solidification chemical reactions.

[0003] At present, manual stirring is commonly used for mechanical composition determination in soil resource surveys, and then the straw method or hydrometer method is used for analysis to obtain data calculation. This method has the following problems. Low work efficiency; large-scale determination consumes a lot of manpower and material resources; the sedimentation barrel will inevitably shake during manual stirring, and if an electric stirrer is used, the spiral blade will aggravate the shaking of the sedimentation barrel; manual stirring is difficult to maintain the uniformity of the sample; manual stirring has the situation that the number of stirring times, strength, stroke, etc. are difficult to unify, resulting in inconsistent sample stirring and dispersion effects, which affects the measurement results when the hydrometer method is used for analysis.

[0004] Therefore, a new technical solution is urgently needed in the prior art to solve this problem. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is: an automatic stirring device for soil solution, comprising a lifting bracket, an operation controller, a sedimentation barrel and a stirring body; the lifting bracket comprises a directional slide rod, an electric slide rail, a slider, a base, a cover plate and a lifting connection plate; the directional slide rod and the electric slide rail are both vertically arranged between the base and the cover plate; the slider is slidably connected with the electric slide rail; the middle part of the lifting connection plate is fixed to the slider, and the two ends of the lifting connection plate are slidably connected with the directional slide rod; a plurality of dovetail grooves are arranged on the base; a positioning slide plate is embedded in the dovetail groove; the positioning slide plate is slidably connected with the dovetail groove, and the positioning slide plate and the dovetail groove are combined to form a sedimentation barrel station; the operation controller is used to control the operation of the lifting bracket; the operation controller is arranged on the base;

[0007] A base is fixedly arranged at the bottom of the sedimentation barrel; the base is slidably connected with the dovetail groove; there are plural stirring bodies, which are arranged corresponding to the stations of the sedimentation barrel, and the top of the stirring body is vertically fixed on the lifting connection plate.

[0008] Preferably, the stirring body comprises a stirring rod and a stirring blade; the top end of the stirring rod is vertically fixed on the lifting connecting plate, and the stirring blade is arranged at the bottom end of the stirring rod; the stirring blade is a flat plate structure with a plurality of through holes.

[0009] Preferably, the electric slide rail is provided with an origin switch, an upper limit switch and a lower limit switch.

[0010] Through the above design scheme, the utility model can bring the following beneficial effects:

[0011] 1. The operation controller controls the operation of the lifting bracket, driving the stirring body to automatically stir the solution, saving a lot of manpower;

[0012] 2. The positioning slide plate and the dovetail groove are combined to form multiple sedimentation barrel stations, which can stir multiple samples at the same time, saving a lot of manpower while achieving the unification of stirring times, strength, stroke, etc., making the stirring and dispersion effect consistent and improving the accuracy of the hydrometer method measurement results;

A base is fixed at the bottom of the sedimentation barrel; the base is connected with the dovetail groove in a sliding manner; the positioning slide is connected with the dovetail groove in a sliding manner, and the positioning slide and the dovetail groove are combined to form a sedimentation barrel station; in this way, the sedimentation barrel can be stably set on the station, accurately positioned and prevented from shaking during stirring.

Such a stirring body will not produce shaking caused by spiral blades, and the stirring effect is better when the lifting bracket moves up and down automatically. BRIEF DESCRIPTION OF THE DRAWINGS
