A measuring device and method for visualization of three-dimensional spatial distribution of seedbed soil blocks

Abstract

A measuring device and method for visualizing the three-dimensional spatial distribution of seedbed soil blocks belongs to the technical field of agricultural machinery. The sampler of the present invention is a cube frame structure, and the lower surface of the bottom plate is attached to the upper surface of the tripod of the measuring device. The two sides of the tripod are The inserting boards are respectively connected with the two holes of the bottom plate, the fan-shaped angle gauge in the measuring device is fixed on the upper end of the cylindrical rod of the bracket, the distance gauge, ring and angle pointer of the distance gauge assembly are fixed in sequence from front to back, and the lower end of the depth gauge The conical positioning needle is fixedly connected, and the ring is movably connected with the upper end of the cylindrical rod and the fan-shaped angle ruler. The depth gauge can move up and down with the distance gauge through the connecting piece; the device of the present invention is simple in structure, easy to operate, and can be used It is not only used for measuring seedbed soil clods, but also can be used to measure the coordinate position of other items in three-dimensional space. It is versatile and can also realize the visual representation of seedbed soil clods in three-dimensional space, which can be used to compare seedbed soil under different treatment conditions in a more intuitive way. distribution of blocks.

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 soil blocks in a seedbed. Background technique [0002] Existing studies have shown that the state of the topsoil 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. Through the evaluation of the distribution information of the seedbed clods, it can be used to guide the research on the broken parts of the seedbed clods. At present, quantitative analysis method is mostly used to evaluate the effect of soil block crushing in seedbed, and there is little relevant research on the visualization of the spatial distribution of soil blocks in the seedbed after operation. Therefore, the pres...
