Description

Technical Field

[0001] The utility model belongs to the technical field of laboratory experimental breeding equipment, and particularly relates to a device for breeding and collecting earthworms in a laboratory. Background Technique

[0002] Earthworms play an important role in the ecosystem. As a model organism in the soil, there are many studies, especially in soil toxicology. However, the growth of earthworms has 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. Most of the existing earthworm breeding and collecting devices are simply designed and have single functions, making it difficult to meet the requirements for controlling the growth environment and collecting earthworms in a laboratory environment. Currently, most earthworm breeding is carried out using opaque box bodies or box structures, making it difficult to control light and humidity. This traditional breeding structure is not suitable for laboratories to observe the growth habits of earthworms. In addition, the existing earthworm collection methods mainly rely on manual labor, with low efficiency and easy damage to earthworms, which has an adverse impact on the smooth progress of subsequent experiments. Content of the Utility Model

[0039] Embodiment 1

[0040] As Figures 1 to 6 shown, a device for laboratory earthworm breeding and collection includes an earthworm breeding box 1.

[0041] The earthworm breeding box 1 is a transparent box made of plexiglass. The transparent box is 0.60 meters long, 0.50 meters wide and 0.60 meters high. The transparent box is convenient for observing the activities and growth of earthworms in the box.

[0042] Referring to Figure 1 and Figure 4 , a transparent plastic interception net 3 is covered on the top of the earthworm breeding box 1.

[0044] The nozzle 12 is installed below the transparent plastic interception net 3. The nozzle 12 can be installed in the earthworm breeding box 1 through a bracket. The nozzle 12 should not affect the user's feeding of earthworms, because when the earthworms need to be fed, the user feeds them by opening the transparent plastic interception net 3 on the top of the earthworm breeding box 1.

[0045] The installation method of the nozzle 12 and the fully automatic booster pump 16 can also refer to the installation of the nozzle 12 on the box body through a placer in the patent application with the publication number CN112262824A.

[0046] Reference Figure 2 , the nozzle 12 is provided with fine holes, which can atomize water to ensure uniform humidity. When the humidity in the earthworm breeding box 1 is lower than the set humidity of the humidity sensor 10, the controller 13 starts the fully automatic booster pump 16. The fully automatic booster pump 16 pumps water from the external water tank through the water inlet pipe 15, and the water flow then enters the nozzle 12 through the rubber hose 14. The nozzle 12 starts to spray water. When the humidity in the earthworm breeding box 1 reaches the set humidity target, the controller 13 controls the fully automatic booster pump 16 to stop working.

[0049] Reference Figure 1 , a stainless steel drawer 5 is provided below the tempered glass bottom plate 4. The stainless steel drawer 5 is a sliding drawer installed in the earthworm breeding box 1. Four corners of the stainless steel drawer 5 are provided with pulleys 7. The pulleys 7 are installed in the drawer slide rail 21. The side of the stainless steel drawer 5 is provided with a stainless steel handle 17, which is convenient for pulling out and retracting the stainless steel drawer 5. Among them, the mechanism of the sliding drawer is well-known, so it will not be elaborated here.

[0050] Refer to Figure 5 and Figure 6, a vibration screening device is provided inside the stainless-steel drawer 5. The vibration screening device includes a stainless-steel screen 9, which is installed in the upper-middle part of the stainless-steel drawer 5. Drill holes at the edges of the stainless-steel screen 9 and the stainless-steel drawer 5 with an electric drill to form openings 18, and screw into the openings to fix the stainless-steel screen 9 on the stainless-steel drawer 5. The specification of the stainless-steel screen 9 is 12 mesh. The vibration screening device also includes a vibration motor 19, which is installed below the stainless-steel screen 9. According to actual needs, it can also be installed above the stainless-steel screen. The vibration motor 19 is connected to the stainless-steel screen 9.

[0053] Refer to Figures 1 to 6 , the working process of a device for laboratory earthworm breeding and collection proposed in this application is as follows:

[0054] When using this device, it should be checked first whether there are any problems affecting its use. When using this equipment, connect it to an external power supply to start the humidity control system, and the whole device starts to operate;

[0055] The user sends earthworms and soil into the earthworm breeding box 1 for earthworm breeding, and controls the light and dark environment through the light-tight plastic baffle 2 to simulate the natural growth environment of earthworms. When it is necessary to feed the earthworms, the user can feed them by opening the transparent plastic interception net 3 on the top of the earthworm breeding box 1.

[0056] The user can monitor the humidity level inside the earthworm breeding box 1 in real time through the humidity sensor 10. When the humidity is lower than the set value, the humidity sensor 10 starts the fully automatic booster pump 16 through the controller 13. The fully automatic booster pump 16 pumps water from an external water tank through the water inlet pipe 15, and the water flow is then transported to the nozzle 12 through the rubber hose 14. The nozzle 12 atomizes and sprays the water into the earthworm breeding box 1 to increase the humidity. When the humidity reaches the set value, the controller stops the operation of the fully automatic booster pump 16 to keep the humidity inside the earthworm breeding box 1 within an appropriate range.

[0057] The top of the earthworm breeding box 1 is covered with a transparent plastic interception net 3, which ensures air circulation while preventing earthworms from escaping. When earthworms need to be collected, the user can pull out the tempered glass bottom plate 4 at the bottom of the earthworm breeding box 1, and the earthworm and soil mixture will fall into the stainless steel drawer 5. Start the vibration motor 19, and the stainless steel screen 9 starts to vibrate, screening the soil particles to the bottom of the stainless steel drawer 5, while the earthworms remain on the stainless steel screen 9, and the earthworm collection work can be carried out.

[0058] Through the universal wheels 8 installed at the bottom of the whole device, the user can easily adjust the position of the device according to the experimental needs. During use, the user should regularly check the operation status of the humidity control system to ensure that there is enough water in the water tank, and check whether the rubber hose 14, the water inlet pipe 15 and the nozzle 12 are unobstructed. At the same time, regularly clean the stainless steel drawer 5 and the stainless steel screen 9 to ensure the screening effect and the normal operation of the equipment.

[0059] In addition, in order to facilitate the opening of the transparent plastic interception net 3, the light-proof plastic baffle 2 is designed as a box structure surrounded on all four sides without a top and a bottom. During use, an opaque top cover that can be lifted can be installed on the top of the light-proof plastic baffle 2 according to actual needs, or other opaque covers can be covered outside the transparent plastic interception net 3 or the light-proof plastic baffle 2. During use, the number of baffles of the light-proof plastic baffle 2 can also be reduced according to actual needs, such as only setting baffles on two sides.

[0060] Through the above design, the present utility model provides a laboratory earthworm breeding and collection device that can effectively control the growth environment of earthworms, realize the automatic separation and collection of earthworms and soil. This device not only improves the experimental efficiency, reduces manual operation, but also ensures the safety of earthworms during breeding and collection, and has good practical value.
