Abstract

The invention relates to a novel urban green land soil sampler, and relates to the field of samplers which can be suitable for soil quality of different urban green lands. The design solves the problem of how to conveniently collect soil samples under different environments and different soil quality conditions. Compared with other products, the invention improves the drill bit of the traditional appliance. The auxiliary rod is added, and the sampling device can be used for sampling deep soil. And two different types of drill bits are provided in the aspect of the drill bit, wherein the M-type drill bit is used for sampling the texture hard soil, and the N-type drill bit is used for sampling the texture loose soil. The bottom of the M-type drill bit and the bottom of the N-type drill bit are changed into pointed ends, so that the drill bits can be easily inserted into soil with different soil qualities. At the top of the two drills, the drill threads are arranged outside the pipe (the sampling space is not occupied), and the drill threads can be connected with a handle with threads inside the pipe barrel during installation, so that a set is formed. When the sample is taken out again, the drill bit and the handle can be unscrewed, so that the soil sample is taken out from the top of the drill bit.

Description

Soil sampler for urban green land soil

Technical Field

The invention relates to a soil sampler which can be used for sampling urban green land soil, in particular to a soil sampler which can be simultaneously suitable for collecting soil samples of different soil qualities.

Background

The urban green land soil is an important environmental foundation for cultivating dense vegetation in cities and exerting the ecological function of the green land. The air permeability, water storage property, fertilizer retention property and the like of the soil are beneficial to the growth of the plants in the green land, and further influence the performances of purifying and beautifying the air of the urban green land. The collection of urban green land soil is a key step in the study of soil texture. At present, the length of a traditional soil sampler is fixed, one soil sampler can only collect one kind of soil, the bottom of the soil sampler is free of any protective measures, the collected soil sample is easy to leak, and the soil sample resource is wasted. The traditional sampler is used for a long time, a large amount of money and labor are consumed, and scientific research work is mainly not in a laboratory and is wasted on the collection of soil samples of urban green land in a large amount. The collection of deep soil sample is traditionally used to be "luoyang shovel", but because the improper can destroy the sample of technical key way during soil sampling, and do not have safeguard measure, loose dry soil is omitted extravagantly easily. New equipment and a new method for sampling deep soil are urgently required in production and scientific research. In urban greening and soil ecological environment research, the soil sampler makes up the defects of the traditional soil sampler, and provides convenience for research on deep soil nutrients and moisture of urban green land soil.

Disclosure of Invention

The utility model discloses an aim at satisfies the requirement of the convenient sample of soil and the sample of different soils, solves the technical problem of more accurate collection soil sample among the soil testing, reduces in the sampling process because of the loose unrestrained waste of soil sample, makes the process of gathering the sample more convenient, high-efficient, and this novel soil sampling ware has the advantage of simple easy operation. The invention provides a special soil sampling tool which has simple structure, stable performance, convenient use and simple operation and can be used for soil detection, investigation and quality evaluation projects. The specific technical scheme is as follows: based on the importance of the soil sampler, the invention is a novel soil sampler for the green land of the city. The three groups are as follows: grip, auxiliary rod, drill (model M, N). An auxiliary rod with replaceable length is arranged below the handle, and threads are arranged below the auxiliary rod to replace different types of drill bits. Compared with other products, the invention improves the drill bit in the traditional mode, and the three elastic sheet devices are arranged on one side of the drill bit close to the soil, so that more soil samples can be obtained under the same surface area. The M type is a traditional type and is more suitable for firmer soil, but loose and desertified soil is not easy to store and collect, and the N type is suitable for looser soil, such as dry desertified soil, sandy soil and the like. N type drill bit (the department contains the shell fragment, can only contract inwards, the shell fragment is inwards contracted during drill bit downstream, during the drill bit upstream, get back to the primary importance through sample weight shell fragment, prevent soil leakage) increased three shell fragment in the sample tube barrel on M type drill bit's basis, soil upwards fills when the drill bit extrudees downwards (will be even hard, the condition under the soil natural state is kept as far as possible), open-ended three shell fragment is extruded to the state of remaining silent because the decurrent action of gravity of soil, the inside shrink of shell fragment does not influence the soil sample, can prevent simultaneously that loose soil sample accident from dropping. The drill threads on the tops of the two drill bits are arranged outside the pipe (the sampling space is not occupied), and the drill bits can be connected with the handle with the threads inside the pipe barrel during installation, so that the drill bits are combined into a whole. When the sample is taken out again, the drill bit and the handle can be unscrewed, so that the soil is taken out from the top of the drill bit. The plug may be pushed through an opening in the side of the bit if it is plugged. Two kinds of drill bits are the tip, change and inject hard soil sample, have realized convenient collection soil sample under different environment. The detachable structure is also convenient for users to a great extent. The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Detailed Description

The utility model discloses in concrete application process, including following step:

A. according to the soil texture state, a proper drill bit is selected, and if hard soil (such as silt-shaped soil and hard soil texture) is met, an M-type drill bit is selected. And screwing the grip and the M-shaped drill bit at the interface, and uniformly pressing the two grips tightly gripping the grip downwards with force until the sampling depth is reached. When the drill bit is pulled out, the drill bit is slowly pulled out in order to avoid the sample from shaking off and avoid the drill bit from being pulled out quickly as much as possible.

B. And selecting a proper drill according to the soil quality state, wherein an N-type drill is selected if the soil (sandy soil) is loosened in a texture manner. And screwing the N-shaped drill bit of the grip at the interface, and uniformly pressing the two grips tightly gripping the grip downwards with force until the sampling depth is reached. When the drill bit is pulled out, the drill bit can be pulled out in an auxiliary mode of rotating if the drill bit feels hard.

(if the combination of the handle and the drill bit can not reach the sampling depth, an auxiliary rod can be added between the handle and the drill bit so as to meet the sampling requirement)

The above description is only the preferred embodiment of the present invention.
