[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The purpose of this invention is to provide a device for insects to actively feed on plant branches, thereby solving the problems existing in the prior art and effectively improving the accuracy of observation results.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown, this embodiment provides a device for insects to actively feed on plant branches, comprising:

[0028] Insect cage 1 has a circular inlet at the center of its upper end, through which experimental insects can enter the insect cage 1. Different experimental insects can be used for different experiments. In this embodiment, the experimental insect is the wood tussock moth.

[0029] Plant cages 2 are provided in several units, and each plant cage 2 is connected to an insect cage 1 via a connecting pipe 3. During the experiment, the length of each connecting pipe 3 is kept consistent to ensure that the distance from each plant cage 2 to the insect cage 1 is the same. A circular plant hole is provided at the center of the lower end of each plant cage 2, through which the plant branch to be observed can be inserted into the plant cage 2. This is the plant to be observed in this embodiment.

[0030] Support device 4 is installed at the lower end of insect cage 1 and is used to support insect cage 1.

[0031] In actual use, the entire device is moved to the experimental site by the movable support device 4. The plant branches to be observed are inserted into the corresponding plant cages 2, and then several experimental insects are put in through the insect inlet. The researchers observe which plant branches in the plant cages 2 the experimental insects go to, which facilitates the research on the feeding characteristics of the experimental insects.

[0032] In this embodiment, the insect cage 1, the plant cage 2, and the connecting tube 3 are all made of transparent material. The purpose of using transparent material is to allow staff to see the movement trajectory of each experimental insect intuitively, which makes it convenient for staff to observe.

[0033] In this embodiment, the insect cage 1, plant cage 2, and connecting pipe 3 are all made of existing transparent plastic material, which has the advantages of low price and light weight, thereby reducing the overall manufacturing cost of the device and making the entire device easy to transport.

[0034] In this embodiment, the connecting pipe 3 is an adjustable telescopic pipe. By controlling the extension and retraction of the adjustable telescopic pipe, the distance between each plant cage 2 and the insect cage 1 can be adjusted (it should be noted that during the experiment, the length of each adjustable telescopic pipe after extension should be kept consistent) so as to be suitable for plants of different volumes.

[0035] In this embodiment, the adjustable telescopic tube includes a first telescopic outer tube and a first telescopic inner tube. The inner diameter of the first telescopic outer tube is larger than the outer diameter of the first telescopic inner tube, allowing the first telescopic outer tube to slide on the outside of the first telescopic inner tube. The end of the first telescopic outer tube away from the first telescopic inner tube is bonded and fixed to the outer wall of the insect cage 1, and the end of the first telescopic inner tube away from the first telescopic outer tube is bonded and fixed to the outer wall of the plant cage 2. A first positioning groove is provided on the outer wall of the first telescopic inner tube. A first positioning spring and a first positioning post are installed in the first positioning groove. One end of the first positioning spring is fixed to the bottom of the first positioning groove, and the other end of the first positioning spring is fixedly connected to the first positioning post. A plurality of first positioning holes are spaced apart on the side wall of the first telescopic outer tube, through which the first positioning post can pass.

[0036] When it is necessary to adjust the length of the first telescopic outer tube and the first telescopic inner tube, the first positioning pin needs to be pressed to disengage it from the original first positioning hole. Without the limiting effect of the first positioning pin, the first telescopic outer tube and the first telescopic inner tube can slide relative to each other. When they have extended or retracted to the expected length, the first positioning pin can be inserted back into the corresponding first positioning hole, thereby achieving the positioning function of the first telescopic outer tube and the first telescopic inner tube.

[0037] In this embodiment, the support device 4 includes a support telescopic tube, which has the same structure as the adjusting telescopic tube. The support telescopic tube includes a second telescopic outer tube and a second telescopic inner tube. The inner diameter of the second telescopic outer tube is larger than the outer diameter of the second telescopic inner tube. The second telescopic outer tube is slidably connected to the outside of the second telescopic inner tube. The second telescopic inner tube is inside the second telescopic outer tube and extends upward. The upper end of the second telescopic inner tube is fixedly connected to the lower end of the insect cage 1. A second positioning groove is provided on the outer wall of the second telescopic inner tube. A second positioning spring and a second positioning post are installed in the second positioning groove. One end of the second positioning spring is fixed to the bottom of the second positioning groove, and the other end of the second positioning spring is fixedly connected to the second positioning post. A plurality of second positioning holes are distributed at intervals on the side wall of the second telescopic outer tube, through which the second positioning post can pass.

[0038] When it is necessary to adjust the length of the second telescopic outer tube and the second telescopic inner tube, the second positioning pin needs to be pressed to disengage it from the original second positioning hole. Without the limiting effect of the second positioning pin, the second telescopic outer tube and the second telescopic inner tube can slide relative to each other. After they have extended or retracted to the expected length, the second positioning pin can be inserted back into the corresponding second positioning hole, thereby achieving the positioning function of the second telescopic outer tube and the second telescopic inner tube.

[0039] In addition, those skilled in the art can replace the support telescopic tube with other devices with telescopic functions, such as hydraulic cylinders, pneumatic cylinders, and electric push rods.

[0040] In this embodiment, a movable base 5 is installed at the lower end of the support device 4, and the lower end of the second telescopic outer tube is bonded and fixed to the upper surface of the movable base 5. The lower surface of the movable base 5 is provided with several casters, preferably existing casters with brakes.

[0041] In actual use, staff can use the movable base 5 to move the entire device. When the device moves to the working position, the brake device on the caster wheel can be activated to ensure the overall stability of the device and prevent it from moving during the experiment.

[0042] In this embodiment, both the insect cage 1 and the plant cage 2 are cylindrical structures. In addition, those skilled in the art can replace them with cuboid shells or cube shells, etc., and are not limited to this one.

[0043] In this embodiment, each plant cage 2 has a cage support tube 6 between its lower surface and the support device 4. The number of cage support tubes 6 is the same as the number of plant cages 2, and they correspond one-to-one. The cage support tube 6 is a telescopic tube structure. Specifically, the cage support tube 6 can be the same as the telescopic support tube structure described above. The cage support tube 6 includes a third telescopic outer tube and a third telescopic inner tube. The inner diameter of the third telescopic outer tube is larger than the outer diameter of the third telescopic inner tube. The third telescopic outer tube is slidably connected to the outside of the third telescopic inner tube. The upper end of the third telescopic inner tube is hinged to the lower end of the plant cage 2. The outer wall of the third telescopic inner tube is provided with a third positioning groove. A third positioning spring and a third positioning post are installed in the third positioning groove. One end of the third positioning spring is fixed to the bottom of the third positioning groove, and the other end of the third positioning spring is fixedly connected to the third positioning post. Several third positioning holes are distributed at intervals on the side wall of the third telescopic outer tube, and the third positioning post can pass through the third positioning holes. A hinge seat is fixed on the lower surface of the plant cage 2 and the support device 4. The two ends of the cage support tube 6 are respectively hinged to the hinge seat of the lower surface of the plant cage 2 and the support device 4. That is, the end of the third telescopic outer tube away from the third telescopic inner tube is hinged to the hinge seat on the support device 4, and the end of the third telescopic inner tube away from the third telescopic outer tube is hinged to the lower end of the plant cage 2.

[0044] In practical use, the plant cage 2 is supported by the cage support tube 6. In addition, when the connecting tube 3 is extended or retracted to adjust the distance between the insect cage 1 and the plant cage 2, the tilt angle of the cage support tube 6 will also change accordingly, and the length of the cage support tube 6 also needs to be adjusted accordingly.

[0045] In this embodiment, there are 2-5 plant cages 2, and each plant cage 2 is evenly distributed around the insect cage 1. Those skilled in the art can set the specific number of plant cages 2 according to actual needs, and it is not limited to 2-5, but can be more.
