Seedbed soil block three-dimensional space distribution visualization measuring device and method

Abstract

The invention discloses a seedbed soil block three-dimensional space distribution visualization measuring device and method, and belongs to the technical field of agricultural machinery.The sampler isof a cube frame structure, the lower surface of a bottom plate of the sampler is attached to the upper surface of a triangular support of a measurer, and two inserting plates of the triangular support are connected with two holes of the bottom plate respectively; a fan-shaped goniometer in the measurer is fixedly connected to the near upper end of a cylindrical rod of a support, a distance measuring ruler, a circular ring and an angle pointer of a distance ruler assembly are fixedly connected in sequence from front to back, the lower end of a depth measuring ruler is fixedly connected with aconical positioning needle, and the circular ring is movably connected with the near upper end of the cylindrical rod and the lower portion of the fan-shaped goniometer. The depth measuring ruler andthe distance measuring ruler can form up-and-down and front-and-back relative movement through a connecting piece; the device is simple in structure and convenient to operate, can be used for measuring seedbed soil blocks, can also be used for measuring coordinate positions of other objects in a three-dimensional space, has universality, can also realize visual representation of the seedbed soil blocks in the three-dimensional space, and is used for comparing distribution conditions of the seedbed soil blocks under different treatment conditions in a more intuitive manner.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a measuring device and method for visualizing the three-dimensional spatial distribution of seedbed soil blocks. Background technique [0002] Existing studies have shown that the state of the plow layer soil is not only related to the quality of sowing, but also the distribution of soil aggregates directly affects seed germination and crop yield, and the smaller the soil aggregates, the better the emergence, growth and yield of crops. By evaluating the distribution information of soil clods in the seedbed, it can be used to guide the research on the broken parts of soil clods in the seedbed. At present, the evaluation of the crushing effect of soil clods in seedbeds mostly uses quantitative analysis methods, and there are few related studies on the visualization of spatial distribution of soil clods in seedbeds after operation. Therefore, the present i...
