Abstract
The utility model relates to a modified soil stratified sampling device, specifically speaking improve sampling device to insert plate size and structure, alleviate bury most advanced stress concentration problem and improve the intensity and the rigidity of picture peg of picture peg. A modified soil stratified sampling device, includes the sample bucket, separates board cavity, baffle slide, picture peg, the baffle includes: carry an arm -tie and n sheetmetal, wherein n is the positive integer, is equipped with n on the inner wall of sample bucket to the baffle slide, and a n sheetmetal imbeds n respectively can follow n respectively and slide to the baffle slide baffle slide, a n sheetmetal, and the picture peg is gradually narrow structure of main part, characterized by: the picture peg buries and holds to the isosceles trapezoid structure, and the trapezoidal bottom width that goes up is 100mm, belongs to the agricultural machinery field. The stratified sampling device after this kind of method improvement picture peg structure is adopted, the requirement of margin of safety and high rigidity can be satisfied.
Description
Technical field
The utility model relates to a kind of soil layering sampler of improvement, specifically improve size and the structure of sampler plate, alleviate plate and to bury point stresses concentration problem improve the strength and stiffness of plate.
Background technology
Advocate in the society advancement setting up " resource-conserving " and " environmentally friendly " at current this, precision agriculture becomes the new trend of current social development, for agricultural modernization development provides technical support and superior equipment.Wherein, the sampling of soil, collection and surveying work just become the important component part of precision agriculture development, and fine or not degree direct influence of its sampling is to the accuracy of measurement result.With the soil of eco-functional regionalization, Daxing'an Mountainrange for research object, in soil housekeeping, soil is sampled on the spot.In view of the soil of different soil can not be carried out separately sampling by existing soil sample equipment, try to carry out optimal design on a kind of basis of soil layering sampler, improve size and the structure of plate, and then promote sampling work high-quality, complete efficiently.For soil collecting equipment provides accurate guarantee, for precision agriculture development lays a good foundation.
Summary of the invention
The purpose of this utility model is:
In order to solve existing soil layering sampler plate in sampling process, the most advanced and sophisticated problem that stress is concentrated that often occurs of burying, directly causes the wearing and tearing at plate tip and fractures, affecting the serviceable life of plate.Design a kind of soil layering sampler of improvement, comprise sample bucket, dividing plate chamber, dividing plate slideway, plate, described dividing plate comprises: lift plate and n sheet metal, wherein n is positive integer, and the inwall of sample bucket is provided with n to dividing plate slideway, and n sheet metal embeds n respectively to dividing plate slideway, n sheet metal can slide along n to dividing plate slideway respectively, plate is the gradually narrow structure of main body, it is characterized in that: plate buries end for isosceles trapezoidal structure, and trapezoidal upper bottom width is 100mm.Under the prerequisite meeting plate working strength and rigidity, board plug structure be optimized and improve, to meet the request for utilization of plate, reducing its maintenance, operating cost, improve its serviceable life.
Accompanying drawing explanation
Fig. 1 is existing soil layering sampler cut-away view, and in Fig. 1,1 is lift plate, and 2 is dividing plate chamber, and 3 is sample bucket, and 4 is dividing plate slideway, and 5 is n sheet metal, and 6 is plate;
Fig. 2 is the soil layering sampler cut-away view after improving board plug structure, and in Fig. 2,6 is plate.
Embodiment
A kind of soil layering sampler of improvement, comprise sample bucket, dividing plate chamber, dividing plate slideway, plate, described dividing plate comprises: lift plate and n sheet metal, wherein n is positive integer, and the inwall of sample bucket is provided with n to dividing plate slideway, and n sheet metal embeds n respectively to dividing plate slideway, n sheet metal can slide along n to dividing plate slideway respectively, plate is the gradually narrow structure of main body, it is characterized in that: plate buries end for isosceles trapezoidal structure, and trapezoidal upper bottom width is 100mm.In FIG, because the most advanced and sophisticated A place static stress and distortion that buries of soil layering sampler plate 6 is maximum, rigidity is minimum, is the part needing to carry out structure improvement.Therefore, its size and structure are improved in the basis that former plate material Q235 and thickness 5mm is constant, as shown in Figure 2.In fig. 2, change plate 6 into isosceles trapezoidal structure by isosceles triangular structure, tip B C size of burying is increased to 100mm.
Sampler is carried out to the foundation of three-dimensional model in ProE software, import finite element analysis software ANSYS again, stress and strain model is carried out to the soil layering sampler after improving, applying displacement constraint and load carry out solving calculating, after being improved, the Finite element analysis results table of comparisons of stratified sampling device plate and existing plate, as shown in table 1.
Plate after table 1 improves and the Finite element analysis results table of comparisons of existing plate
As can be seen from Table 1, maximum stress suffered by the plate after improvement is 0.12Mpa, reduces 0.03Mpa than maximum stress 0.15Mpa suffered by existing plate.Due to the permissible stress of plate material Q235, obviously, thus improve after Q235 layers of material sampler plate meet intensity request for utilization.Meanwhile, the plate maximum deformation quantity after modified node method is 0.371 × 10
-4m, more existing plate maximum deformation quantity reduces 0.237 × 10
-4m, and improvement its maximum distortion of back card/back board and maximum stress all do not appear at plate front end B and C place.Therefore, the Be very effective after modified node method, maximum stress and maximum distortion reduce all to some extent, add the serviceable life of plate.
Stratified sampling device after adopting this kind of method to improve board plug structure, can meet the requirement of margin of safety and high rigidity, and processing, easily manufactured, and decrease maintenance, operating cost, effect of optimization is good.Consider each side factor, adopt during suggestion practical application and improve back card/back board replacement existing apparatus plate.This optimization is proposed, design and application for soil layering sampler has established good theoretical foundation, reasonably planning and first-hand data are provided to the optimization problem of sampler, technical indicators such as improving the practicality of precision agriculture and reliability is of great practical significance.
