A soil sample collection tool

Abstract

The invention provides a soil sample collection tool, which includes a handle, a connecting piece, a pedal piece, a spring, a baffle plate and a fresh-keeping film roll. The pedal part is fixed on the outer wall of the connecting part; one end of the connecting part is vertically connected to the handle, and the other end is sequentially provided with a sample inlet, a sample collection groove and a mantle groove; the sample inlet is set at the port of the connecting part. The spring, the baffle and the fresh-keeping film roll are arranged in the mantle tank; the inner walls on both sides of the mantle tank are provided with scale lines for measuring the height of the soil sample entering the inner side of the mantle tank. It also includes an elastic soil sheet, which is laid flat on the inner wall of the bottom of the sample collection tank, one end of which is fixed at the injection port, and this end is flush with the injection port; the other end of the elastic soil sheet is close to the mantle groove, And the end is connected with a pull cord. The elastic soil sheet set in the present invention is beneficial to take out the soil samples after entering the sample collection tank, and the mantle film tank has better distribution and collection functions for soil samples, and through the setting of the sample inlet, the soil samples will not stick to the sample collection The inner walls on both sides of the groove facilitate the complete removal of the sample.

Description

【Technical field】 [0001] The invention relates to the technical field of a soil sample collection device, in particular to a soil sample collection tool. 【Background technique】 [0002] Soil sample collection is involved in many fields, especially in the development of agricultural science and technology, the collection of soil samples is essential. Soil sample collection is an important part of soil analysis work, which is directly related to the correctness of the analysis results. Soil sample collection is random, extensive and representative. When collecting soil samples, it is necessary to pay attention to the size of the soil sample, the collection point, and the collection time. and collection range. Generally, there are 5 to 20 sampling points, which are selected according to the different directions of soil research, and each sampling point is as quantitative as possible to make the work more effective. When collecting soil samples, it is necessary to take out and...

Problems solved by technology

As far as the current situation is concerned, most of the soil sample collection tools are generally T-shaped or more complex structures. It is troublesome to collect soil with general devices, or the soil sample will stick to the inner wall of the sample collection tank when collecting soil, causing Sampling is difficult to quantify

One of the most prominent problems to be solved now is how to prevent the soil sample from sticking to the inner wall of the bulldozing device, and how to quantitatively take out the soil sample
