Description

Technical Field

[0001] This utility model relates to the field of plant protection technology, and in particular to an indoor insecticide testing device. Background Technology

[0002] Indoor insect efficacy tests are used to evaluate the toxicity of insecticides to insects in indoor environments and are a commonly used testing method in plant protection.

[0003] For example, Chinese utility model patent application number 202321801836.2 discloses an indoor insect efficacy testing device, including a screw-top cap, a transparent bottle glued to the screw-top cap, two half-caps on the left and right sides set at the top opening of the transparent bottle, and a transparent cover covering the outside of the transparent bottle and the half-caps. The bottom of the transparent cover is screwed to the screw-top cap, and a hole is provided between the two half-caps for plants to pass through. A mesh is provided at the top opening of the transparent cover, and a rubber block is provided at the top mounting opening of the transparent cover.

[0004] While the aforementioned patent allows the entire plant to be used in efficacy testing, effectively ensuring leaf freshness, enabling insects to feed normally, and guaranteeing the accuracy of efficacy testing, it still has certain shortcomings. By piercing the rubber block with the syringe needle and pushing the syringe piston to water the plant through the needle, it is difficult to achieve uniform watering of the plant, which is not conducive to uniform moisture retention of the plant leaves. In practical applications, some plant leaves may dry out due to insufficient watering, causing the test insects to dislike feeding on them, resulting in significant experimental errors.

[0005] Therefore, it is necessary to provide an indoor insecticide testing device to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an indoor insecticide testing device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an indoor insecticide testing device, comprising a test chamber, wherein a spray pipe is rotatably installed on the top of the test chamber, and a plurality of nozzles are fixedly connected to the outer surface of the spray pipe. The top of the test chamber is also provided with a rotating mechanism and a water supply mechanism, wherein the water supply mechanism is used to supply water to the spray pipe, and the rotating mechanism is used to drive the spray pipe to rotate and spray water evenly onto the plants.

[0008] As a further description of the above technical solution: the rotating mechanism includes a frame fixedly installed on the top of the test chamber. A drive motor is fixedly installed on the top of the inner wall of the frame. A drive gear is fixedly connected to the output end of the drive motor. A driven gear meshes with the outer surface of the drive gear. The driven gear is fixedly sleeved on the outer surface of the spray pipe. By setting up the rotating mechanism, the spray pipe and multiple nozzles can be driven to make circular motion around the branches or plants, thereby achieving uniform water spraying on the leaves of the branches or plants. This ensures the uniformity of water spraying to moisturize the leaves and avoids the situation where some leaves dry out and become inactive due to uneven water spraying, which is beneficial to improving the accuracy of the test results.

[0009] As a further description of the above technical solution: the water supply mechanism includes a water tank fixedly installed on the top of the test chamber, a water pump fixedly installed on the bottom of the inner wall of the water tank, a water supply pipe fixedly connected to the outlet end of the water pump, and the end of the water supply pipe away from the water pump fixedly passing through the water tank and rotatably connected to the top end of the spray pipe through a sealed bearing. Through the coordinated use of the water supply mechanism, the spray pipe and the nozzle, water can be sprayed onto the branches or leaves of the plant.

[0010] As a further description of the above technical solution: a hole for the plant to pass through is provided in the middle of the bottom of the test chamber, and an annular suturing sponge is fixedly connected inside the hole. A positioning cylinder is fixedly connected to the bottom of the test chamber at the position corresponding to the hole, and a plant culture dish is placed below the test chamber at the position corresponding to the positioning cylinder.

[0011] As a further description of the above technical solution: the test chamber has a door hinged to the front, and a permanent magnet is fixedly installed on the front of the test chamber and at the position corresponding to the side of the door. The door is made of metal material. The permanent magnet magnetically attracts the door, making it magnetically attracted and fixed on the test chamber, thus playing a certain role in fixing the door to prevent insects from escaping from the gap between the door and the test chamber during the test.

[0012] As a further description of the above technical solution: the top of the test chamber is equipped with a storage battery and a control panel.

[0013] This utility model has the following beneficial effects:

[0014] Compared with existing technologies, this indoor insecticide testing equipment, through the coordinated use of a water supply mechanism, spray pipes, and nozzles, can automatically spray water onto the surface of branches or plant leaves within the test chamber. Furthermore, the rotating mechanism drives the spray pipes and multiple nozzles to move in a circular motion around the branches or plants, thereby achieving uniform water spraying onto the leaves. This ensures the evenness of watering and moisturizing the leaves, preventing uneven watering that could lead to some leaves drying out and becoming inactive, and thus improving the accuracy of the test results.

Detailed Implementation

[0021] 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.

[0022] Reference Figure 1-4This utility model provides an indoor insecticide testing device, which includes a test chamber 1. The test chamber 1 has several densely packed ventilation holes on its outer side. A spray pipe 2 is rotatably installed on the top of the test chamber 1. Several nozzles 3 are fixedly connected to the outer surface of the spray pipe 2. The top of the test chamber 1 is also provided with a rotating mechanism 4 and a water supply mechanism 5. The water supply mechanism 5 is used to supply water to the spray pipe 2, and the rotating mechanism 4 is used to drive the spray pipe 2 to rotate and spray water evenly on the plants.

[0023] The rotating mechanism 4 includes a frame 401 fixedly installed on the top of the test chamber 1. A drive motor 402 is fixedly installed on the top of the inner wall of the frame 401. A drive gear 403 is fixedly connected to the output end of the drive motor 402. A driven gear 404 meshes with the outer surface of the drive gear 403. The driven gear 404 is fixedly sleeved on the outer surface of the spray pipe 2. The output end of the drive motor 402 rotates to drive the drive gear 403 to rotate, which in turn drives the driven gear 404 to rotate, thereby driving the spray pipe 2 to rotate. This causes multiple nozzles 3 to make circular motions around the branches or plants, thereby achieving uniform water spraying on the leaves of the branches or plants. This ensures the uniformity of water spraying to moisturize the leaves and avoids the situation where some leaves dry out and become inactive due to uneven water spraying, which is beneficial to improving the accuracy of the test results.

[0024] The water supply mechanism 5 includes a water tank 501 fixedly installed on the top of the test chamber 1. The top of the water tank 501 is provided with a water inlet to facilitate the experimenter to fill the water tank 501 with water. A water pump 502 is fixedly installed on the bottom of the inner wall of the water tank 501. The outlet end of the water pump 502 is fixedly connected to a water supply pipe 503. The end of the water supply pipe 503 away from the water pump 502 is fixedly inserted through the water tank 501 and rotatably connected to the top of the spray pipe 2 through a sealed bearing 11. The water supply mechanism 5 can supply water to the spray pipe 2 and spray water onto the blades through the nozzles 3 on the outside of the spray pipe 2.

[0025] A hole is provided in the middle of the bottom of the test chamber 1 for plants to pass through. An annular slit-filling sponge 6 is fixedly connected inside the hole. The annular slit-filling sponge 6 can fill the gap between the branches or plants and the inner wall of the hole when they are inserted into the hole, preventing insects from escaping through the gap. A positioning cylinder 12 is fixedly connected to the bottom of the test chamber 1 at the position corresponding to the hole. A plant culture dish 7 is placed below the test chamber 1 at the position corresponding to the positioning cylinder 12. The plant culture dish 7 is used to hold culture medium (such as nutrient solution or potting soil) to cultivate fresh branches or plants, improve plant activity, and prevent them from drying out and becoming inactive quickly.

[0026] The test chamber 1 has a hinged door 8 on its front. A permanent magnet (not shown in the figure) is fixedly installed on the front of the test chamber 1 and at the position corresponding to the side of the door 8. The permanent magnet makes the door 8 similar to a magnetic door. The door 8 is made of metal. The permanent magnet magnetically attracts the door 8 and fixes it to the test chamber 1, which plays a certain role in fixing the door 8 to prevent insects from escaping from the gap between the door 8 and the test chamber 1 during the test.

[0027] The top of the test chamber 1 is equipped with a storage battery 9 and a control panel 10. The water pump 502 and the drive motor 402 are electrically connected to the storage battery 9 through the control panel 10. The storage battery 9 is used to supply power to the water pump 502 and the drive motor 402, and the control panel 10 is used to control the start and stop of the water pump 502 and the drive motor 402.

[0028] Working principle: In use, first overcome the magnetic attraction of the permanent magnet to the door 8 and open the door 8. Then, place the fresh branch or plant with the pesticide sprayed on the leaves into the test chamber 1, and pass the branch or plant through the inside of the annular sizing sponge 6 and the positioning tube 12 in sequence, so that the branch or plant is located at the bottom of the test chamber 1 and inserted into the plant culture dish 7. The combination of the annular sizing sponge 6 and the positioning tube 12 can limit the branch or plant, making it close to a vertical position. Add an appropriate amount of culture medium (nutrient water or potting soil) into the plant culture dish 7. Then, adjust the opening of the door 8 to a near-closed state. At this time, put the insect to be tested into the test chamber 1, and then completely close the door 8 to conduct the insect pesticide test. The experimenter observes and records the mortality of the insects in the test chamber 1 through the ventilation holes on the outside of the test chamber 1.

[0029] During the experiment, to prevent the leaves from dehydrating and dying, it is necessary to spray water on the leaves regularly to keep them moist. First, add an appropriate amount of clean water to the water tank 501 through the water inlet. Then, start the water pump 502 and drive motor 402 through the control panel 10. The water pump 502 delivers the clean water in the water tank 501 to the spray pipe 2 through the water supply pipe 503. Finally, the nozzles 3 spray the water onto the leaves of the branches or plants. At the same time, the output end of the drive motor 402 rotates, driving the drive gear 403 to rotate, and driving the driven gear 404 meshing with it to rotate, which in turn drives the spray pipe 2 to rotate. This causes multiple nozzles 3 to make circular motions around the branches or plants, thereby achieving uniform water spraying on the leaves of the branches or plants. This ensures the uniformity of water spraying to keep the leaves moist and avoids the situation where some leaves dry out and die due to uneven water spraying, which helps to improve the accuracy of the experimental results.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
