Embodiment 1

[0020] Embodiment 1 is a collection and separation device for soil animals. The container body 1 is a cone-shaped body made of transparent plastic, thick at the top and thin at the bottom, open at the top, and spike-shaped at the bottom of the cone. The inner cavity of the container body 1 is provided with a set of separation ladders stepped from top to bottom, and the separation ladders 2 are placed on the annular boss 11 on the inner wall of the container body 1 . The middle part of each separating ladder 2 is a screen 21, and the periphery of the screen 21 is a downwardly bent arc skirt, which is an umbrella-like structure with a flat top, which can prevent soil animals from escaping. A guide plate 3 is provided on the separation ladder plate 2 on the top floor, and the guide plate 3 extends from the top of the inner wall of the container body 1 to the screen mesh 21 of the separation ladder plate 2 on the top floor to form a bowl-shaped converging guide structure. The siev...

Embodiment 2

[0023] Embodiment 2. The structure of this embodiment is basically the same as that of Embodiment 1. The material of the container body 1 is also transparent plastic. The difference is that the container body 1 is a segmented structure, which is segmented according to the position of the separating ladder plate 2. The number of segments Corresponding to the number of separation risers 2, each section has a separation riser 2, and each section is screwed. Each section is integrally formed with its separated ladder plate 2, and a plug-in handle 12 is installed on the top section, and a light-emitting diode is installed on the handle 12. In this embodiment, before inserting the sampling, the sections where the bait is placed are assembled, after the sampling is completed, the soil animals can be taken out by unscrewing each section, and each section can be used as a sieve sample container, which can further screen out the soil and Soil animals are separated cleanly.

Abstract

The invention provides a collection and separation device for soil animals. The collection and separation device comprises a container body internally provided with attracting substances, wherein thecontainer body is a cone-shaped body of which the upper end is provided with an opening, the cone base is in a spinal shape, an inner cavity of the container body is internally provided with separation ladder plate groups in a ladder shape from top to bottom, the middles of separation ladder plates are provided with screens, and an umbrella-shaped anti-escape structure is formed by extending to the inner wall of the lower portion of the container body from the edges of the screens; the separation ladder plate on the top layer is provided with a guide plate, the guide plate extends to the screen of the separation ladder plate on the top layer from the top end of the inner wall of the container body to form a bowl-shaped converging guide structure, and sieve holes of the screen of the separation ladder plate on each layer gradually decrease from top to bottom. Multiple layers of the separation ladder plates are provided with sieve holes gradually decreasing from top to bottom, the animals of smaller body shape can fall onto the bottoms of the container body, and the animals of larger body shape can fall onto the separation ladder plate on each layer in sequence, thereby classifiedlytrapping the soil animals, reducing the later sorting difficulties, and improving the work efficiency.

Description

technical field [0001] The invention relates to a collection device for soil animals, in particular to a device for collecting and separating soil animals which is convenient to put into farmland. Background technique [0002] Tens of thousands of soil animals live in the soil. They are an important part of the soil ecosystem. They participate in the decomposition of biological residues, change the properties of the soil, and affect the formation and development of the soil and the material cycle and energy flow of the ecosystem. are all significant. The related research on soil animals can provide soil zoological evidence for evaluating the quality of ecosystems, restoring damaged ecosystems, and maintaining and managing ecosystems. Soil animals are widely distributed, and there are soil animals almost anywhere on the earth's surface where life exists. The individual quantity and types of soil animals are very rich. Collembola, mites and nematodes together constitute the ...
