Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , figure 2 As shown, the present invention includes a handle and a drill body 9 that can be opened and closed. The handle includes two circular hollow nested steel pipes, that is, an outer steel pipe 1 and an inner steel pipe 2; wherein the outer steel pipe 1 contains a second A spring 3 is provided with an opening 6 on the upper wall of the outer steel pipe 1 . One end of the inner steel pipe 2 is nested in the outer steel pipe 1 and can reciprocate axially relative to the outer steel pipe 1. The first spring 3 is located at the end of the nested end of the inner steel pipe 2 and the inner wall of the outer steel pipe 1. between. The pipe body in which the inner steel pipe 2 is located in the outer steel pipe 1 is provided with a positioning device that is positioned in the opening 6 when the drill body is opened. The positioning ...

Abstract

The invention relates to soil sample collecting equipment, in particular to a soil sample collector for collecting a soil sample in a plough layer for various conventional soil sample analysis. The soil sample collector comprises a handle and a drilling body, wherein the handle comprises two hollow nested steel tubes; a first spring is accommodated in the outer-layer steel tube; an open pore is arranged on the upper wall of the outer-layer steel tube; one end of the inner-layer steel tube can be nested in the outer-layer steel tube in a reciprocating moving manner; the first spring is positioned between the end part of the inner-layer steel tube and the inner wall of the outer-layer steel tube; a positioning device positioned in the open pore when the drilling body is opened is arranged on a tube body of the inner-layer steel tube positioned in the outer-layer steel tube; the drilling body is formed by hinging two parts with the same structure; and the two parts are respectively connected with the inner-layer steel tube and the outer-layer steel tube. The soil sample collector has small size; the handle and the drilling body are compactly combined; when the soil sample collector is free from influencing the growth of peripheral plants when being used for collecting the soil samples on the surface layer of soil, and the advantages are especially remarkable when the crop plants are higher and the planting density is larger; and the soil sample collector can be also used for transplanting plants at the seedling stage.

Description

technical field [0001] The invention relates to soil sample collection equipment, in particular to a soil sample collector which can collect plow layer soil samples for analysis of various conventional soil samples. Background technique [0002] For agricultural production, timely collection of soil samples for the determination of physical and chemical indicators will help to understand the state of soil nutrients in a timely manner, and corresponding measures can be taken in a timely manner according to the nutrient status of crops to effectively ensure high and stable crop yields. [0003] At present, the method of grasping the soil nutrient status during crop growth is mostly to use soil auger sampling, and there are many kinds of soil augers, but most of them have long handles. These soil augers are easy to operate when the crop plants are short, and when the plants are tall to collect soil samples, the rotation of the handle will affect the growth of surrounding plants...
