Description

A paddy field soil profile sample collector

technical field

The utility model relates to a paddy field soil profile sample collector, which is suitable for collecting 0-40cm paddy field soil profile soil samples.

Background technique

During the investigation of paddy field soil profiles, it was found that the current soil auger or tube sampler would seriously disturb and compact the soil samples, and often even damage the surface layer, so there is a great need for a method that can collect undisturbed soil profile samples without damaging the sampling points and Vegetation tools.

Utility model content

The purpose of the utility model is to provide a paddy field soil profile sample collector which is simple, easy to operate, good in tensile strength, compressive strength, corrosion resistance, light in weight and small in size in view of the deficiencies in the prior art.

The utility model realizes above-mentioned object through following technical scheme:

A paddy field soil profile sample collector, comprising a cylindrical collection cylinder, the two ends of the collection cylinder are open, the middle part is hollow, a sealing cover is installed on one end of the collection cylinder, and the edge of the cylinder wall at the other end forms a cutting edge. The collection tube is provided with a scale in the vertical direction, and the collection tube is provided with a plurality of collection holes communicating with the inside of the collection tube at positions corresponding to the scales.

The collection tube is also equipped with a handle that facilitates the insertion and extraction of the collection tube into and out of the paddy field soil.

The sealing cap is screwed on the collecting tube.

The collection tube has a height of 30-50 cm and an inner diameter of 7-8 cm.

The collection tube is provided with a collection hole every 5cm along the scale, and the diameter of the collection hole is 3-5cm.

The utility model adopting the above-mentioned technical scheme has the following advantages: a sealing cover is placed on the upper part of the collection tube to seal the collection tube and facilitate operation; the bottom of the sealing cover is provided with a handle to facilitate the insertion and extraction of the collection tube; The lower wall of the cylinder is sharper, forming a cutting edge, so that it can be easily inserted into the deep layer of the soil, so that the collected soil will not be compacted and mixed. There are collection holes on the wall of the collection cylinder, so that it is convenient to sample the positions of each scale. In this way, the soil at different depths and regions can be reasonably sampled and classified, so as to ensure that the soil profiles of paddy fields with different heights of 0-30cm are collected at one time, and the soil between the soil layers does not interfere with each other, so that the measurement results are more accurate.

To sum up, the device is easy to disassemble, small in size, easy to carry, and can be operated by one person. The operation is simple, and the depth of soil can be selected. Lightweight and small in size, it is suitable for paddy field soil profile sample collection.

Description of drawings

Fig. 1 is the structural representation of the utility model;

FIG. 2 is a cross-sectional view of FIG. 1 .

Detailed ways

Below in conjunction with accompanying drawing, the specific implementation manner of this patent is described in further detail.

As shown in Figures 1 and 2, a paddy field soil profile sample collector includes:

A cylindrical collection tube 1, the collection tube 1 is made of stainless steel tube, the inside diameter of the collection tube 1 is 7cm, and the height is 40cm. Under the label, the 0cm baseline must be very clear, make a mark every 1cm, and only need to write the scale at 5cm and its multiples. Drill six circular holes vertically downward on the collection tube 1 as the collection holes 4. The centers of the collection holes 4 are located at the scales of 5cm, 10cm, 15cm, 20cm, 25cm and 30cm in turn. The diameter of the collection holes 4 is 3cm.

The upper end of a collecting tube 1 is provided with the screw thread of high about 2cm, can be screwed into sealing cap 2 in the screw thread, handle 3 is installed on the collecting tube away from the about 1cm place of collecting tube upper end.

The utility model is used in a specific way.

Insert the collecting tube 1 vertically into the soil, cover the sealing cover 2, press the handle 3 firmly with both hands, and then rotate left and right to push the collecting tube 1 downward. When the required depth is reached, the handle 3 is pulled up. After the collection cylinder 1 is extracted from the soil, take samples from the 4 collection holes located at 5cm, 10cm, 15cm, 20cm, 25cm and 30cm with tweezers.
