Description

A kind of soil animal separator

technical field

The utility model belongs to the technical field of agriculture and relates to a soil separator, in particular to a soil animal separator.

Background technique

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. For the collection of soil animals, the Italian scholar Berlesc made a utility model of a drying funnel in the early 20th century, which was improved by Tullgren and widely used. It is called the Tullgren method or the dry funnel method. It is mainly used for the separation and extraction of small and medium-sized soil animals with a body length of 0.2-2 mm. At present, scholars at home and abroad still use the Tullgren method to separate small and medium-sized soil animals. Tullgren separator includes lamp, outer cylinder cover, screen, inner cylinder, funnel, beaker. The size, structure and physical parameters of the Tullgren separator have a great impact on the separation efficiency of soil animals, and there are few reports on this aspect.

Utility model content

The purpose of the utility model is to provide a soil animal separator by improving the Tullgren separator.

The utility model comprises a separator frame, a lamp, a funnel, an aluminum-plastic porous plate, a beaker, a cross bar, a chute, and a funnel frame.

The separator frame consists of struts and cross arms. A horizontally fixed funnel frame is installed on the pole of the separator frame, and the funnel frame is used to place the funnel. The pole has a chute between the cross arm and the funnel frame, and the cross bar is connected to the chute of the pole. Utilizing the chute, the crossbar can change its position, or height, on the strut.

The funnel is installed on the funnel frame. The aluminum-plastic perforated plate is placed in the middle and lower part of the cone of the funnel.

The lamps are installed on the crossbar, and as the height of the crossbar on the pole changes, the height of the lamp on the separator frame also changes accordingly.

The beaker is placed below the funnel and the lamp is above the funnel. Lamps, funnels with aluminum-plastic perforated plates, and beakers form a separation system from top to bottom.

When the utility model is used, the required aluminum-plastic porous plate is installed in the middle and lower part of the cone of the funnel. Put the soil samples that need to be separated into the funnel, and under the heating of the light source of the lamp, the soil animals enter the beaker through the aluminum-plastic porous plate to achieve the purpose of separation.

In the utility model, lamps, funnels with aluminum-plastic porous plates, and beakers can be installed on the same separator frame as required, and multiple separation systems are formed from top to bottom, that is, multiple separation systems are combined together.

The utility model changes the soil temperature by adjusting the height of the lamp. When in use, the soil samples to be separated can be put into a funnel with an aluminum-plastic porous plate and spread flat, and then turn on the lamp to heat. Adjust the distance between the lamp and the funnel as needed. After heating, the temperature in the soil layer in the funnel forms a temperature gradient of high up and low down. The soil animals move from top to bottom and enter the beaker below through the aluminum-plastic porous plate to achieve separation. the goal of.

The utility model is very suitable for the separation and extraction of medium and small soil animals with a body length of 0.2-2mm.

The utility model is an improvement to the traditional collector. (1) The heat source has changed from a sleeve joint type to a separate suspension type. Hang the lamp above the soil sample, heat the soil sample with light, and capture soil animals. The traditional collector changes the intensity of the heat source by changing the wattage of the bulb. The utility model can control the heating intensity of the soil sample by changing the wattage of the lamp, and also by adjusting the vertical distance between the lamp and the soil sample, which is convenient for precise operation. Observe and control the temperature of the soil sample surface. In addition, the lamp of the utility model adopts a spotlight, which can save electric energy. (2) Change the original tubular soil container into a funnel. In this way, it is more flexible and convenient to load and pour soil samples. (3) The aluminum-plastic perforated plate and the funnel are separated. The traditional separation soil cylinder and the screen at the bottom are welded together, resulting in two disadvantages, one is inconvenient to operate, and the other is that the screen is easily damaged due to corrosion. The utility model uses a self-made aluminum-plastic porous plate to replace the iron gauze, which will not be damaged due to rust, and can also be replaced with aluminum-plastic plates of various apertures and densities at any time according to needs, thereby achieving higher separation efficiency. (4) It is also used to catch wet soil animals. When separating wet soil animals, wrap the soil sample with 900-mesh silk gauze.

The utility model can effectively control the temperature and save energy by improving the structure of the conventional separator, and the utility model is convenient to operate, strengthens the human control ability, and improves the separation efficiency.

Two sets of separation systems consisting of lamps 2, funnels 3, and beakers 5 equipped with aluminum-plastic perforated plates 4 were assembled on the same separator frame composed of cross arms 1 and poles 9. After assembling according to the above process, adjust the height of the cross bar 6 through the chute 7, so that the lamp 2 is vertically suspended at 5 cm above the funnel 3, turn on the power, and after heating for 24 hours, the soil animals are separated from the soil sample and collected in a beaker 3 in.

According to needs, on the same separator frame composed of cross arm 1 and pole 9, multiple sets of separation systems composed of lamps 2, funnels 3, and beakers 5 equipped with aluminum-plastic porous plates 4 can be installed, such as four sets . Changing the size of the holes of the aluminum-plastic perforated plate 4 can separate soil animals of different sizes.
