Embodiment Construction

[0027] soil animal separator see figure 1 . It is mainly composed of an outer cylinder 1, an inner cylinder 4, an incandescent lamp 2, a temperature probe 3, a screen 5, a screen 6, a screen 7, a separation frame 8, a funnel 9, a beaker 10 and a temperature control system 11.

[0028] Both the outer cylinder 1 and the inner cylinder 4 are made of metal plates with a thickness of 1.5 to 2 mm. The outer cylinder is 18 cm high and 16 cm in diameter, and the inner cylinder is 16.5 cm high and 14 cm in diameter. The top of the outer cylinder 1 is closed, the heating source (incandescent lamp) 2 is fixed on the top of the outer cylinder 1, the wire of the incandescent lamp 2 is connected to the temperature control system 11, and there are four ￠1cm ventilation holes on the top of the outer cylinder except for a lamp holder of the incandescent lamp 2 And a ￠1cm temperature measuring hole, the temperature measuring probe 3 is inserted into the soil sample to be tested through the tem...

Abstract

The invention belongs to the field of agricultural technologies and particularly relates to an SCM-controlled (single-chip microcomputer) soil-animal separator. The SCM-controlled soil-animal separator is composed of three metallic screen mesh layers. The screen meshes are different in shape and pore shape, and the pores stagger. Each screen mesh layer is provided with certain spacing. The top of an outer cylinder is provided with a plurality of air holes. A temperature control is controlled through an SCM; actually measured temperature is compared to set temperature through the SCM; thyristor operating angle is controlled so as to control the power of an incandescent lamp and control the temperature of a separator soil sample. The SCM-controlled soil-animal separator has the advantages that the problems that the pore diameter of the separator screen meshes is either too large or too small, liquid in a collector overflows and temperature is either too low or too high are solved, the power of a light source can be conveniently changed according to difference in soil sample thickness and humidity, with no need of changing incandescent lamps different in watt level or adjusting height between the lamp source and the soil sample, optimal temperature is set more accurately, and the optimal effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a soil animal separator controlled by a single-chip microcomputer. Background technique [0002] There are tens of thousands of soil animals living in the soil. They are an important part of the soil ecosystem. They participate in the decomposition of biological residues, change soil properties, and affect the formation and development of soil and the material cycle and energy of the ecosystem. Mobility matters. At the beginning of the 20th century, the Italian scholar Berlesc invented the insect drying funnel, which was improved by Tullgren and widely used. It is called the Tullgren method or the dry funnel method. Mainly used for body length 0.2 ～ Separation and extraction of small and medium soil fauna up to 2 mm. At present, scholars at home and abroad mostly use the Tullgren method to separate and extract small and medium-sized soil animals. However, the ...
