Background
With the increasing research on the regional distribution and ecological functions of soil animals, how to separate soil animals from soil by using a separation device is an important first step in the relevant research. Whether soil animals can be separated out quickly or not directly influences the carrying efficiency of related researches, whether high-quality soil animal samples can be separated out or not determines the difficulty degree of follow-up observation.
The principle of the existing separation and insect drying equipment is mainly that strong light is added on the upper part of soil by utilizing the negative phototaxis and high temperature resistance of soil animals, the temperature of the equipment reaches a certain temperature, the soil animals move, and the animals are separated from the soil by utilizing the influence of gravity.
The main structures of the common insect drying equipment are a bulb, a funnel, a soil sample sieve and a receiving container. The general working principle is as follows: the funnel is provided with a soil sample sieve, the soil sample is placed in the soil sample sieve, and the soil animals are forced to move downwards and pass through the soil sample sieve by utilizing the illumination and heat provided by the bulb above the funnel, and finally fall into the receiving container. The insect drying device is simple in device, and can perform certain soil animal separation work, but has the following defects: when soil animals are separated, soil particles in the soil sample sieve easily fall into the receiving container, so that the separation quality is reduced; the temperature and the illumination intensity required for separation are provided only by the bulb, so that the working efficiency is low; the open device also makes during operation easily attract some phototaxis insects to fly into or impurity gets into the receiving container, influences experimental data.
The prior separation and insect drying equipment has a portable insect drying device and an insect drying box which can separate a large amount of soil animals in a laboratory, but in experimental use, the separation and insect drying equipment has the following problems:
1. the conventional separation and drying device takes a long time to separate soil animals.
2. The common insect separating and drying equipment only supports the separation of dry soil animals or wet soil animals and has single function.
3. In the process of carrying out soil animal separation experiments by using common separation and insect drying equipment, soil particles with small particle sizes are carried by soil animals passing through a soil sample sieve and fall into a receiving container together due to the action of gravity, so that the experimental observation is influenced by the existence of the soil animals and the soil particles in the receiving container.
4. Conventional separation and drying apparatus requires relatively frequent alcohol addition by laboratory personnel to the receiving vessel when separating the dried soil animals.
5. The temperature required for drying the insects is mainly provided by heating of the bulbs, and the temperature of the soil is difficult to meet the optimal value required for drying the insects in different seasons and different environments.
6. In a common insect separating and drying device or an insect drying box, the required light source is provided by independent bulbs, and the efficiency is low.
7. Ordinary separation and dry by fire worm device simple structure and mostly be the semi-open type, lack stability during the experiment, if the collision appears or rock, make soil sample sieve in soil impurity fall into receiving container or soil sample spill device easily.
