Description

Technical Field

[0001] The invention relates to a device for cultivating earthworms in a laboratory, and belongs to the field of laboratory experimental cultivation equipment. Background Art

[0002] Earthworms have a long history of use in traditional Chinese medicine formulas. They are also widely used as bait and feed. Earthworm feces contain a variety of rich amino acids and can be used as organic fertilizers. Therefore, earthworm farming also has good market prospects. However, the growth of earthworms has very high environmental requirements. If the temperature, humidity and light intensity do not meet the survival requirements of earthworms, it is easy to cause the death of earthworms. At present, earthworm farming mostly adopts opaque boxes or box structures, and the control of light is mostly manual and timed to increase the light. This traditional farming structure is not suitable for laboratory observation of earthworm growth habits. At the same time, because earthworms are light-avoiding, the previous structure will easily escape from the breeding layer, causing losses to earthworm farming. Summary of the invention

[0005] The present invention adopts a fully transparent box. At the same time, the "spherical rubber small sucker" and "glass wall protrusion" that fix the pull-out screen and the interception net are all fully transparent, ensuring the illumination in the breeding box during the day, so that the earthworms are always kept in the breeding matrix of the "pull-out screen". At night, when the outdoor light intensity is small, the "light-controlled induction lamp" above the interception net lights up, because the "transparent plastic interception net" has good light transmittance, ensuring that there is illumination above the "pull-out screen", and the "light-controlled induction lamp" below the pull-out screen lights up, ensuring that there is illumination below the "pull-out screen", and also making the earthworms always stay in the breeding matrix of the "pull-out screen". Thus, the purpose of preventing earthworms from escaping from the breeding matrix is ​​achieved.

[0006] The technical solution further defined in the present invention is: a spray device is arranged on the top of the transparent box structure, and the spray device includes a placement device fixedly arranged on the left and right side walls of the box, and a plurality of spray pipes are arranged in parallel on the placement device, and a plurality of nozzles are arranged on the spray pipes.

[0007] Furthermore, the placer is movably mounted on the top edges of the left and right side walls of the box body through a slide groove opened below it along its length direction. A group of plug holes are opened on the placer, and the spray pipes are plugged into the plug holes.

[0008] Furthermore, one end of the spray pipe is sealed, and the other end is connected to a water inlet hose. The other end of the water inlet hose is connected to a fully automatic booster pump arranged on the side wall of the box structure below the interception net, and the fully automatic booster pump is connected to a water source.

[0009] Furthermore, a humidity sensor is installed on the side wall of the box above the pull-out screen, and the humidity sensor is communicatively connected with the full-automatic booster pump.

[0010] Furthermore, it also includes a pull-out type earthworm manure collection chamber arranged at the bottom of the breeding box, and a water outlet pipe is arranged below the collection chamber.

[0011] Furthermore, a rotatable foldable lamp stand is installed on the top of the box structure, and the light-controlled induction lamp above the interception net is installed on the rotatable foldable lamp stand.

[0012] Furthermore, the light-controlled induction lamp below the pull-out screen is a rechargeable LED light-controlled induction lamp.

[0013] Furthermore, handles are provided on the side ends of the pullable screen and the intercepting net respectively.

[0014] Furthermore, universal wheels are installed at the bottom of the transparent box structure.

[0015] Beneficial effects: Compared with the prior art, the laboratory earthworm breeding device provided by the present invention has the following advantages: through the design of the transparent box structure and the supplementary lighting of two light-controlled induction lamps, the purpose of preventing earthworms from escaping from the breeding matrix is ​​achieved; at the same time, it is convenient to observe the influence of temperature, humidity and lighting environment on the growth process of earthworms; through the height difference design of the front wall and the rear, left and right side walls of the transparent box structure, it is convenient to push, pull and seal the interception net, and at the same time, a suitable space is reserved for the installation of the spraying equipment; by arranging glass wall protrusions and spherical rubber small suction cups on the side walls of the transparent box structure, the screen and the interception net are fixed and load-bearing; through the design of the interception net, earthworms can be prevented from climbing up and escaping, and the mesh design does not affect the light exposure; by arranging a water outlet pipe under the collecting chamber, excess liquid in the collecting chamber can be discharged at any time to prevent liquid from being deposited in the collecting chamber, causing excessive humidity in the earthworm growth environment.
