Technical Field
The invention relates to the technical field of mite collection, in particular to a device for efficiently separating and collecting mites.
Background
Mites belong to a class of small animals of the phylum arachnoidea, the eurocomias, the phylum of arthropoda, the body size is generally around 0.5 mm, some as small as 0.1 mm, most species less than 1 mm. Mites have been found in the world in a number of 50000, next to insects. A number of categories are related to medicine. The mites are closely related to the health of people, and the mites harm the stored matters, so that the quality of the stored matters is reduced, even the use value of the stored matters is completely lost, and great economic loss is caused for people; some species may also be lodged on the body surface and in the body of humans, causing acariasis in the corresponding tissues and organs; some kinds of excretions, secretions, are extremely strong allergens, such as dust mites and house dust mites, which can cause allergic diseases in humans. Therefore, it is important to the understanding and research work of the flour mites.
Acquisition of research materials is the basis of research work. In practice it is often necessary to separate the mites from dust, flour, rice, feed or other carriers. The existing separation method plays an important role in actual work, but when the sizes of mites and carrier particles are close, carrier particles are mixed in the screening result, mites cannot be separated cleanly, and a large number of clean mites are sometimes needed in actual scientific research work.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 3, a device for efficiently separating and collecting mites comprises a barrel 1, a barrel cover 2 arranged at the top of the barrel 1, a first groove 21, a second groove 22, an elastic ring 23, air holes 24, a cold light source 3, a sample separating screen 4, a carrier placing table 41, a transparent pipe barrel 5, a through hole 51 and a black film 6.
The cylinder 1 is made of light-tight materials. The top of the barrel cover 2 is provided with an air hole 24, and the right center of the bottom of the barrel cover 2 is provided with a strip-shaped cold light source 3. The bottom of the barrel cover 2 at the periphery of the cold light source 3 is sequentially provided with a sample separating screen 4 and a transparent barrel 5. The bottom of the tub cover 2 is provided with a first recess 21 and a second recess 22. The sample separating sieve 4 and the transparent tube 5 are respectively inserted into the first groove 21 and the second groove 22, and the sample separating sieve 4 and the transparent tube 5 are connected with the barrel cover 2 through the elastic ring 23. The aperture of the sample separating screen 4 is 0.1-1 mm, the bottom of the sample separating screen 4 is provided with a carrier placing table 41, and the carrier placing table 41 is contacted with the inner wall of the bottom of the cylinder body 1.
The outer wall of the transparent tube 5 is covered with a black film 6, and the transparent tube 5 and the black film 6 are provided with through holes 51. The transparent tube 5 is made of transparent plastic or transparent glass, and the bottom of the transparent tube 5 is contacted with the inner wall of the bottom of the cylinder 1. The width of the black film 6 is 1/2-3/4 of the height dimension of the transparent tube 5, and the horizontal center lines of the black film 6 and the transparent tube 5 are on the same straight line.
When separating and collecting mites, the carriers containing mites are placed on the carrier placing table 41, the sample separating sieve 4 and the transparent tube 5 are respectively installed on the barrel cover 2, the barrel cover 2 is installed on the barrel body 1, and the cold light source 3 is turned on. Since mites have phototaxis, they climb out from the carrier placement stage 41 toward the sample sieve 4. Since the body size of mites is generally about 0.5 mm, some are as small as 0.1 mm, most types are smaller than 1mm, the aperture of the sample separating sieve 4 is 0.1-1 mm, and the aperture of the sample separating sieve 4 is selected according to the types of mites. Mites climb out of the sample sieve 4 from the through holes 51 to the back of the black film 6. The cylinder 1 is made of a light-tight material and forms a dark environment with the black film 6, mites can stay on the back of the black film 6, and then the mites on the back of the black film 6 are collected.
The invention can rapidly and effectively obtain a large number of mites required by experiments, and the prior art has low efficiency and poor effect. The mites collected by the invention are pure and free of carrier scraps, and a large amount of carrier scraps are adhered to the prior art. The invention has simple and convenient operation process, complicated working procedures and great consumption of manpower and material resources in the prior art. The mites collected by the invention are all surviving individuals and have complete limbs, and the mites collected by the prior art have a certain limb injury.
