Embodiment Construction

[0028] The specific embodiment of the present invention, as shown in the accompanying drawings, is a drum-type soil aggregate stripper, which includes a drum-type soil sieve 1, a sample drum 2 and a speed-regulating motor base. The base of the speed-regulating motor is composed of a switch 9, an indicator light 8, a speed-regulating device, a timing device, a reversing device, a power adapter device, a transmission device and other auxiliary parts; The window is equipped with a cover plate 20 to fix the drum-type soil sieve. A rubber ring 12 made of rubber material is arranged on the edge of the sample drum disc to increase the friction with the transmission wheel. The other end of the sample drum has a pouring hole 13 It is used to pour out the ground soil sample powder, and it is usually blocked by the pouring hole plug 14; the drum-type soil sieve is made of a perforated steel plate with a cylindrical frame, one end of which is welded with a steel plate as the bottom, and th...

Abstract

The invention discloses a roller type soil aggregate stratified stripper, which comprises a roller type soil screen, a sample roller and a speed adjusting motor base, wherein the speed adjusting motor base comprises a transmission wheel which is in frictional transmission with the exterior of the sample roller and the roller type soil screen is fixed in the sample roller. The roller type soil aggregate stratified stripper has the advantages that the usage is convenient, the error is reduced, the operation time is saved and the work efficiency is increased. According to the invention, manual stripping is replaced by a simple mechanical mechanism, so that uncertain error caused by manual operation is avoided; by building a relatively accurate mathematical model of the radial distribution of matter in the soil aggregate along the aggregate with the assistance of a simple functional relationship, the roller type soil aggregate stratified stripper can process soil aggregates or aggregate samples with a wide diameter scope and is especially capable of processing small grain-sized samples which are hard to process with manual stripping; meanwhile, the quality reliability of stripped matter of the soil aggregate or aggregate samples can be effectively improved and the artificial error is reduced.

Description

technical field [0001] The invention relates to a stripper, in particular to a drum type soil aggregate layer stripper. Background technique [0002] Soil aggregates are an important part of soil science research, and their composition has an important impact on soil nutrients and water and the growth of crops. Due to the limitation of research methods, previous studies on soil aggregates only treated it as a whole, ignoring the internal physical structure and spatial variation of soil aggregates in the research process. The invention of this instrument will realize the layering and stripping of soil aggregates, and technically make it possible to accurately establish a mathematical model of the distribution of various substances in soil aggregates (such as plant nutrients, pesticide residues, heavy metal pollutants, etc.), so it is useful for enriching soil It is of great significance to improve scientific research methods and promote the development of soil science. Con...
