Embodiment 1

[0031] The quantitative compost sampler includes an ellipsoidal drill bit 1, a closeable screw device 5, a first movable link device 8, a sample collection cylinder 10, a closed agitator 11 with a scale, and a second movable link device 13;

[0032] The ellipsoidal drill bit 1 is provided with a sampling hole 3, and the closeable screw device 5 includes a strut 6 and four first blades 7, and the lower right corners of the four first blades 7 are all provided with small square holes 9. The first movable link device 8 includes a first control handle 12, four connecting rods and four first loop hooks 4, and the four first loop hooks 4 pass through the four connecting rods and the first control handle respectively. The outer edges of 12 are connected, and the four first ring hooks 4 of the first movable link device 8 are respectively connected with the four square holes 9 of the closeable screw device 5, and the first movable link device 8 is located in the sample collection cylind...

Embodiment 2

[0042] The installation process of this embodiment is the same as that of the above-mentioned embodiment 1, the main difference lies in the working principle: after the sampling is completed, the closable screw device 5 is in a closed state, and the upper control handle 12 is pressed to make the closable agitator 11 with a scale realize dislocation, Stir the sample in the sample collection cylinder 10 by pushing and turning the upper control handle 12, repeat 3 times to make the sample mix evenly, and finally return the closed agitator 11 with scale to the highest point 0cm scale line, and turn the upper control handle Close it to complete agitation of the sample.

Embodiment 3

[0044] The installation process of this embodiment is the same as that of the above-mentioned embodiment 1, the main difference lies in the working principle: after the stirring is completed, press the lower control handle of the sampler to open the closable screw device 5, and close the closable agitator 11 with scale by pushing , press the position of the movable link device 8 connected to the closed agitator 11 with a scale to achieve the purpose of quantitative sampling, and push out the compost sample into the sample collection bag. After the sample is collected, the closable screw device 5 and the graduated closable agitator 11 can be opened for flushing, and the next sampling can be continued.

Abstract

The invention discloses a quantitative compost sampling device and a sampling method thereof. The quantitative compost sampling device comprises an ellipsoid drilling bit, a closable screw device, a first movable connection rod device, a sample collection barrel, a closable stirrer with scales, and a second movable connection rod device; the center of the closable screw device is connected with a supporting rod, and the right lower corner of each of four blades is respectively provided with a square pore which is connected with the movable connection rod device; the upper part of the movable connection rod device is provided with a control handle, and the control handle can be rotated to drive the closable screw device to sample. The quantitative compost sampling device can quantitatively sample compost and is small in size, convenient to carry, detachable and convenient to wash, simple in structure and low in cost; by designing the ellipsoid drilling bit, the disturbance on the surface of a compost body is small; the closable design of the closable screw device can realize the multipoint sampling; by adopting the closable stirrer with the scales, the problem that a sample is to mixed in a non-uniform manner can be solved; the closable stirrer with the scales can be used as a piston in a closed state, so that a quantitative sampling purpose can be realized.

Description

technical field [0001] The invention relates to a compost sampling device, in particular to a quantitative compost sampler and a sampling method thereof. Background technique [0002] With the rapid development of large-scale animal husbandry, the amount of manure produced by livestock and poultry is also considerable. If these waste treatment and utilization facilities are not effective and are not used in time, the process of composting will inevitably cause environmental pollution. Therefore, livestock and poultry breeding pollution is an important aspect of agriculture. An important part of non-point source pollution. The pollution caused by livestock and poultry manure to the environment mainly spreads through water, soil, air and biology. Due to the complex composition in the composting process of feces, it is the research focus of environmental science, ecology and other disciplines. During the composting of manure, it is often necessary to carry out chemical analys...
