Drying oven structure for separating soil animals by using Tullgren method

Abstract

The invention discloses a drying oven structure for separating soil animals by using a Tullgren method. The drying oven structure comprises a plurality of experimental funnels, and further comprises abottom plate and a top plate, wherein a left side plate, a right side plate and a rear end plate are fixedly connected between the bottom plate and the top plate, a door is hinged to the side edge ofthe left side plate through hinges, a plurality of horizontal laminated plates are fixedly connected between the left side plate and the right side plate, a plurality of bulbs are arranged under thelaminated plates and the top plate, the bulbs of each layer are connected in series and are connected with a temperature control switch in series, and the experimental funnels are arranged on the laminated plates and the bottom plate. The drying oven structure has the advantages of being convenient to install and disassemble, low in cost, time-saving and labor-saving, high in safety and the like,and the drying oven structure can be used for automatically performing drying and soil animal separation on soil samples without manual participation, so that the stability of the temperature of the drying oven is guaranteed, and a good use effect is obtained.

Description

technical field [0001] The invention relates to an oven, in particular to an oven structure for separating soil animals by using the Tullgren method, and belongs to the technical field of soil analysis experiment equipment. 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 Tullgren method has been widely used since its invention and improvement, also known as the dry funnel method, which is mainly used for the extraction of small and medium-sized soil animals with a body length of 0.2-2mm. The measurement principle is to use the characteristics of soil animals to avoid light and heat, put soil or hay samples on the movable upper part of the funnel, and the bulb is g...

Problems solved by technology

However, in the traditional method of manually controlling the light bulb switch of the oven, there is a phenomenon that the temperature of the oven is too high due to human error and forgetting to turn off the light, resulting in the phenomenon that the soil animals have not entered the collection tank and died, and the collection accuracy is not high enough; the temperature control is not strict, and it is relatively expensive. Time-consuming and labor-intensive, cannot be automated, etc.
