Problems solved by technology

Most of the existing elutriation and separation devices with cover sieves are cover sieves. Manual elutriation requires a lot of work, high cost, time-consuming and labor-consuming, waste of water, and after elutriation, the samples of small benthic animals washed out are often not transferred completely, resulting in The sample is lost, which increases the experimental error

Embodiment Construction

[0022] The present invention will be further described below in combination with specific embodiments and with reference to the accompanying drawings.

[0023] See Figure 1 to Figure 4 , an automatic elutriation device for small benthos samples, comprising a housing 1, the housing 1 is provided with a net bag, and also includes a water outlet 3 located above the net bag, and the net bag includes a first net bag 411, the second net pocket 421 located below the first net pocket 411, the third net pocket 431 located below the second net pocket 421, and the diameter of the third net pocket 431 is larger than the second net pocket 421, and the third net pocket 431 is larger than the second net pocket 421. The diameter of the second net pocket 421 is greater than the first net pocket 411, and in the present embodiment, the aperture of the first net pocket 411 is 500 μm, the aperture of the second net pocket 421 is 200 μm, and the aperture of the third net pocket 431 is 31 μm, and o...

Abstract

An automatic washing device for small benthic animal samples comprises a shell provided with three nets inside and a water outlet arranged above the nets. The shell is provided with a pump used for pumping water; the pump is connected to the water outlet through a first water pipe and a second water pipe, and a rotary connector is arranged between the first water pipe and the second water pipe. Compared with the prior art, the device has the advantages that the pump is arranged, after the pump operates, the water is circulated to wash the samples, and force and time are saved; the nets with different meshes are arranged, two batches of the small benthic animal samples with different sizes can be separated through one-step washing, and efficiency is high; the water flow of the water outlet can be adjusted, a protection cover is arranged, insects in the air and other organisms are prevented from mixing with the samples and interfering counting, a water discharge component is capable of moving out of the position above the shell, the interior of the shell can be operated conveniently, water can be used circularly, and water source can be saved.

Description

technical field [0001] The invention relates to the field of elutriation devices for small-scale benthic animal samples in the study of benthic ecological environments such as oceans and lakes, in particular to an automatic elutriation device for small-scale benthic animal samples. Background technique [0002] Small benthic animals are an important link connecting organic debris and primary productivity as well as water layer-benthic coupling, and are an important part of benthic ecosystems; small benthic animals themselves are many economic fish, shrimp and shellfish The high-quality bait for larvae is the basic link in the small benthic food web, and plays an important role in the material cycle and energy flow of the benthic ecosystem; with the deepening of research on the response of small benthic animals to climate anomalies and human disturbances, In particular, the benthic squiggles have been found to be sensitive to environmental stress. In recent years, small benth...
