Embodiment 1

[0031] The quantitative composting sampler includes an ellipsoidal drill bit 1, a closable screw device 5, a first movable connecting rod device 8, a sample collection tube 10, a closeable agitator 11 with a scale, and a second movable connecting rod device 13;

[0032] The ellipsoidal drill bit 1 is provided with a sampling hole 3, and the closable screw device 5 includes a support rod 6 and four first blades 7, and the four first blades 7 are each provided with a square hole in the lower right corner. 9. The first movable connecting rod device 8 includes a first control handle 12, four connecting rods and four first loop hooks 4, and the four first loop hooks 4 respectively pass through the four connecting rods and the first control handle 12 is connected to the outer edge, the four first loop hooks 4 of the first movable link device 8 are respectively connected to the four square holes 9 of the closable screw device 5, and the first movable link device 8 is set in the sampl...

Embodiment 2

[0042] The installation process of this embodiment is the same as the above-mentioned embodiment 1. The main difference lies in the working principle: after the sampling is completed, the closable spiral device 5 is in the closed state, and the upper control handle 12 is pressed to displace the closable agitator 11 with scales. Stir the sample in the sample cylinder 10 by pushing and turning the upper control handle 12, repeat 3 times to make the sample evenly mixed, and finally restore the closeable agitator 11 with scale to the highest point 0cm scale line, and move the upper control handle Close it to complete the stirring of the sample.

Embodiment 3

[0044] The installation process of this embodiment is the same as 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 spiral device 5, and close the closable agitator 11 with graduations by pushing. , Press the position of the movable connecting rod device 8 connected with the scaled closeable agitator 11 to achieve the purpose of quantitative sampling, and push the extruded compost sample into the sample collection bag. After the sample collection is completed, the closable screw device 5 and the scaled 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 sampling device and a sampling method thereof. Background technique [0002] With the rapid development of animal husbandry on a large scale, the amount of livestock and poultry manure is also considerable. If these waste treatment and utilization facilities operate poorly and are not used in time, they will inevitably cause environmental pollution during the composting process. Therefore, the pollution of livestock and poultry breeding is agricultural An important part of non-point source pollution. The pollution of livestock and poultry manure to the environment is mainly diffused through water, soil, atmosphere and organisms. The composting process of manure is the research focus of environmental science and ecology because of its complex composition. In the process of composting manure, chemical analysis and testing are often required. Due to the differences i...
