[0001] The utility model belongs to the field of animal behavior observation equipment. More specifically, the utility model relates to an earthworm behavior pattern observation device. Background Technique

[0002] Pheretima guillelmi is the dried body of the earthworm Pheretima aspergillum ( Pheretima aspergillum ), after removing the internal organs and sediment, mainly distributed in Guangdong and Guangxi, and is a traditional animal medicine in China. Pheretima guillelmi is a genuine medicinal material variety of "Ten Flavors in Guangxi", and the market demand is large. Artificially cultured Pheretima aspergillum is the main source of traditional Chinese medicine resources at present. Observing the behavioral activities of earthworms helps to understand the living habits of earthworms and lay a foundation for the scientific cultivation of earthworms.

[0003] Patent publication number CN220799662U discloses an earthworm cultivation device for cultivating and observing earthworms in a near-natural state, including a cultivation box and an observation mechanism. The side wall and bottom surface of the cultivation box are both reticulated to prevent the earthworms in its inner cavity from escaping. The observation mechanism includes an observation part and a guide column. The observation part is used to observe the burrowing path of earthworms in the soil. The guide column is a hollow transparent column body. The guide column is located in the inner cavity of the cultivation box. The end of the guide column is fixedly connected to the bottom surface of the cultivation box, and the axis of the guide column is perpendicular to the bottom surface of the cultivation box. The observation element of the observation part is located in the inner cavity of the guide column and can be slidably connected to the guide column. This patented technology can observe the burrowing behavior and path of earthworms in the wild environment without damaging the soil where the earthworms live.

[0004] Patent publication number CN216314922U discloses an experimental device for visual observation and cultivation of earthworms in the laboratory.

[0037] like Figure 1-2 As shown, this utility model provides a device for observing earthworm behavior patterns, which includes:

[0038] Lifting structure 1;

[0039] A translation structure is provided on the lifting structure 1;

[0040] An infrared camera 2 is mounted on the translation structure and is connected to an external display device.

[0041] In this technical solution, the lifting structure 1 can adjust the height of the translation structure. The lifting structure 1 can be a hydraulic lifting rod or a pneumatic lifting rod. The translation structure includes a lateral movement structure and a longitudinal movement structure to enable the infrared camera 2 to move in the left-right or front-back directions. The external display device can be a mobile phone or a computer. The infrared camera 2 can connect to the external display device via wireless communication technologies such as Bluetooth to observe earthworms.

[0042] This invention utilizes a translation structure to move the infrared camera 2 above the earthworm, and then uses a lifting structure 1 to adjust the distance between the infrared camera 2 and the earthworm, so as to adjust the focal length of the infrared camera 2 and make it easier to observe the earthworm's behavior when foraging on the ground more clearly.

[0043] In another technical solution, the lifting structure 1 includes four hydraulic lifting rods, which are connected to the four corners of the translation structure to support the translation structure.

[0044] In this technical solution, the hydraulic lifting rod and the translation structure are detachably connected. Specifically, snap-fit ​​holes can be provided on the lower surface of the four corners of the translation structure, and the movable part of the hydraulic rod can be detachably inserted into the snap-fit ​​holes to achieve detachable fixation between the hydraulic rod and the translation structure.

[0045] In another technical solution, the translation structure includes:

[0046] Mounting frame 3 has a rectangular cross-section;

[0047] The lateral movement structure includes a first threaded rod 4, a second threaded rod 5, a first belt 6, and a first motor 7. The first threaded rod 4 is rotatably disposed at the left end of the mounting frame 3, and a first belt 6 pulley is disposed at one end of the first threaded rod 4. The second threaded rod 5 is rotatably disposed at the right end of the mounting frame 3, and a second belt 10 pulley is disposed at one end of the second threaded rod 5.

The second belt 10 is fixedly connected to the sliding block so that the movement of the second belt 10 drives the sliding block 9 to reciprocate within the sliding groove.

[0049] In this technical solution, the first motor 7 drives the second threaded rod 5 to rotate, and the second threaded rod 5 drives the first threaded rod 4 to rotate via the first belt 6. The rotation of the first threaded rod 4 and the second threaded rod 5 causes the moving rod 8 to reciprocate in the front-back direction. The second motor 11 drives the sliding block 9 to reciprocate in the groove of the moving rod 8 via the second belt 10, so as to realize the reciprocating motion of the sliding block 9 in the left-right direction.

[0060] In this technical solution, the tension spring 1203 drives the U-shaped frame 1202 to move downward, so that the tension wheel 1204 installed in the U-shaped frame 1202 can closely abut against the second belt 10, so that the second belt 10 is kept taut between the third pulley, the fourth pulley and the drive wheel of the second motor 11.

[0061] In another technical solution, the telescopic rod includes a first cylinder and a second cylinder. The bottom of the first cylinder is provided with a first limiting edge, and the second cylinder is sleeved inside the first cylinder.
