Embodiment

[0020] Such as figure 1 As shown, a small animal separation device in soil comprises a hollow cylinder section 1 and a funnel 2, the cylinder section 1 has a height of 400mm and a diameter of 400mm, and the diameter of the large end of the funnel 2 is 400mm and the diameter of the small end is 20mm , The height is 400mm.

[0021] The upper opening of the cylinder section 1 is provided with a top cover 4. In this embodiment, the top cover 4 is a circular aluminum plate with a thickness of 1 mm and a diameter of 405 mm. The outer edge of the circular aluminum plate is also provided with a skirt with a thickness of 5 mm. side.

[0022] The lower opening of the barrel section 1 is connected to the large end of the funnel 2. There is a horizontal screen 6 inside the barrel section 1. The screen 6 is located at a distance of 300 mm from the upper opening. The screen 6 is a wire screen with 6 meshes and a diameter of 380 mm. .

[0023] The funnel 2 is fixed on a support frame 5, a...

Abstract

A separation device for small animals in soil comprises a hollow barrel joint and a funnel; an upper opening of the barrel joint is provided with a top cover; a lower opening of the barrel joint is in butt joint with the large end of the funnel; a horizontal screen is arranged in the barrel joint; on the inner wall of the barrel joint, a first supporting block is arranged on the bottom face of the screen; the screen is fixed to the first supporting block; a gap is formed between the outer edge of the screen and the inner wall of the barrel joint; a baffle is arranged on the outer edge of the screen; a motor with an upward rotating shaft is fixed to the middle portion of the screen; fan blades are fixed to the rotating shaft of the motor; a heating plate is arranged below the screen; on the inner wall of the barrel joint, a second supporting block is arranged on the bottom face of a heating plate which is fixed to the second supporting block; a gap is formed between the outer edge of the heating plate and the inner wall of the barrel joint; the funnel is fixed to a supporting frame; and a collecting bottle is arranged below the small end of the funnel. The separation device can efficiently and fast separate the small animals in the soil.

Description

technical field [0001] The invention relates to a device for separating small animals in soil. Background technique [0002] Soil animals are an important part of the soil ecosystem. They participate in the decomposition of biological residues, change soil properties, and play an important role in the formation and development of soil and the material cycle and energy flow of the ecosystem. As one of the indispensable biological components in the ecosystem, soil fauna is not only an important biological indicator of soil fertility, but also closely related to the formation, development, succession of soil and the biogeochemical cycle of the ecosystem. In recent years, there have been more and more studies on the impact and mechanism of land use, fertilization conditions, vegetation types, nitrogen deposition, soil heavy metal pollution, pesticide pollution, and acid rain on soil animal community structure and species diversity. Among these studies, the most critical One of ...
