Description

Technical Field

[0001] This utility model relates to the field of termite bioassay technology, and in particular to a test apparatus for pesticide-treated soil pretreatment of termites. Background Technology

[0002] Soil pretreatment efficacy tests for termites are a crucial step in evaluating pesticide control effects. The core of these tests lies in simulating termite migration behavior in pesticide-treated soil and analyzing the inhibitory effect of the pesticide on termite activity. Traditional experimental setups typically employ a transparent tube connected to bait boxes on both sides. Pretreated soil is filled into the tube, and the activity and pathways by which termites penetrate the treated soil are observed. Such setups must meet basic requirements such as stable connections, controllable environment, and guidance of termite behavior to ensure the accuracy and repeatability of experimental data.

[0003] Traditional instruments have a simple tube structure and lack an effective odor guiding mechanism. The bait odor cannot diffuse gradually to the medicated soil area, making it difficult for termites to be continuously attracted and penetrate the medicated soil layer. The success rate of experiments is generally less than 65%. Traditional instruments rely on frosted spouts or simple sticks for fixation, which are prone to loosening and falling off when the experiment is moved or vibrated, frequently causing the experiment to be interrupted. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a test apparatus for pesticide soil pretreatment of termites.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A test apparatus for pesticide soil pretreatment of termites includes a transparent tube, a first box and a second box located at both ends of the transparent tube, and a connecting mechanism fixedly connected to the outer walls of the first box and the second box respectively. The transparent tube includes an outer hollow tube and an inner hollow tube, with a connecting rod fixedly connected between the outer hollow tube and the inner hollow tube. A filter screen is provided between the outer hollow tube and the inner hollow tube. The connecting mechanism includes a connecting box fixedly connected to the first box and the second box respectively. An insertion rod is provided inside the connecting box, and the insertion rod passes through the outer hollow tube and the inner hollow tube to connect the transparent tube to the first box and the second box.

[0007] Preferably, the outer hollow tube and the inner hollow tube are respectively provided with a first insertion hole and a second insertion hole that match the insertion rod, and the bottom end of the insertion rod can pass through the first insertion hole and the second insertion hole in sequence.

[0008] Preferably, a slip ring is slidably provided inside the connecting box, the insertion rod is fixedly connected to the inner ring of the slip ring, the top end of the insertion rod extends to the top of the connecting box, the bottom end of the insertion rod passes through the connecting box and then through the first insertion hole and the second insertion hole, and a spring sleeved on the insertion rod is fixedly connected between the slip ring and the connecting box.

[0009] Preferably, a pressure rod is hinged to the inner wall of the inner hollow tube, the bottom end of the insertion rod passes through the first insertion hole and the second insertion hole and abuts against the pressure rod, and the other end of the pressure rod abuts against the filter screen.

[0010] Preferably, a counterweight is fixedly connected to the side of the pressure rod, and the end of the pressure rod away from the counterweight in its natural state contacts the inner wall of the inner hollow tube.

[0011] Preferably, a magnet is fixedly installed on the connecting rod, and the filter screen is a metal component.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this application, the transparent tube is quickly connected to the first box and the second box respectively through the connection mechanism, without the need for complex alignment or tool assistance, thus improving assembly efficiency. Its through-type plug connection can ensure that the connection is stable when the instrument is moved or vibrated, avoiding test interruption caused by the loosening or failure of the traditional frosted port, and improving the success rate of the experiment.

[0014] 2. In this application, when the insert rod is inserted, it pushes the pressure rod to rotate around the hinge point. Through the lever principle, the pressure of the insert rod is converted into a uniform clamping force on the filter screen, which effectively prevents the filter screen from shifting due to soil flow or termite activity.

[0015] 3. In this application, the filter screen allows odor transfer between the first and second boxes on both sides, which improves the attraction effect of the bait and can effectively increase the enthusiasm of termites to cross the medicated soil. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown, this utility model provides a test apparatus for pesticide soil pretreatment of termites, including a transparent tube 1, a first box 2 and a second box 3 located at both ends of the transparent tube 1, and a connecting mechanism 4 fixedly connected to the outer walls of the first box 2 and the second box 3 respectively. The transparent tube 1 includes an outer hollow tube 11 and an inner hollow tube 12, with a connecting rod 6 fixedly connected between the outer hollow tube 11 and the inner hollow tube 12. A filter screen 5 is provided between the outer hollow tube 11 and the inner hollow tube 12. The connecting mechanism 4 includes a connecting box 41 fixedly connected to the first box 2 and the second box 3 respectively. An insertion rod 42 is provided inside the connecting box 41, and the insertion rod 42 passes through the outer hollow tube 11 and the inner hollow tube 12 to connect the transparent tube 1 with the first box 2 and the second box 3.

[0024] In this embodiment, the outer hollow tube 11 and the inner hollow tube 12 are respectively provided with a first insertion hole 13 and a second insertion hole 14 that match the insertion rod 42. The bottom end of the insertion rod 42 can pass through the first insertion hole 13 and the second insertion hole 14 in sequence. A slip ring 43 is slidably provided inside the connecting box 41. The insertion rod 42 is fixedly connected to the inner ring of the slip ring 43. The top end of the insertion rod 42 extends to the top of the connecting box 41. The bottom end of the insertion rod 42 passes through the connecting box 41 and then through the first insertion hole 13 and the second insertion hole 14. A spring 44 sleeved on the insertion rod 42 is fixedly connected between the slip ring 43 and the connecting box 41.

[0025] Specifically, by pulling the insertion rod 42, the slip ring 43 can be moved and the spring 44 can be squeezed. After the transparent tube 1 is connected to the first box 2 and the second box 3, the insertion rod 42 is released and reset under the elastic force of the spring 44. The insertion rod 42 passes through the first insertion hole 13 and the second insertion hole 14 in sequence to realize the connection between the transparent tube 1 and the first box 2 and the second box 3. After the instrument is fixed, it is not easy to loosen or fall off when it is moved, which would cause the test to fail.

[0026] In this embodiment, a pressure rod 7 is hinged to the inner wall of the inner hollow tube 12. The bottom end of the insertion rod 42 passes through the first insertion hole 13 and the second insertion hole 14 and then abuts against the pressure rod 7. The other end of the pressure rod 7 abuts against the filter screen 5. A counterweight 71 is fixedly connected to the side of the pressure rod 7. In its natural state, the end of the pressure rod 7 away from the counterweight 71 contacts the inner wall of the inner hollow tube 12.

[0027] Specifically, after the insertion rod 42 passes through the second insertion hole 14, the bottom end pushes the pressure rod 7 to rotate around the hinge point, and the other end abuts against the filter screen 5. Using the lever principle, the pressure of the insertion rod 42 is converted into a fixing force on the filter screen 5 to prevent the filter screen 5 from shifting or falling off. During the experiment, the filter screen 5 is fixed by the clamping force to avoid displacement affecting the experiment. The counterweight 71 ensures that the pressure rod 7 remains hanging down in its natural state.

[0028] In this embodiment, a magnet 61 is fixedly installed on the connecting rod 6, and the filter screen 5 is a metal component.

[0029] Specifically, the filter 5 is placed between the outer hollow tube 11 and the inner hollow tube 12. The magnet 61 attracts the filter 5 to complete the auxiliary positioning. The magnetic attraction provides a non-destructive fixing method, avoiding the use of glue or screws, and can achieve quick disassembly and assembly. The filter 5 can be disassembled without tools, improving replacement efficiency and making maintenance convenient.

[0030] How to use and how to work this device:

[0031] When using this device, the outer hollow tube 11 and the inner hollow tube 12 are first fixed by the connecting rod 6 to form a double-layer structure. A metal filter 5 is placed in the middle and the filter 5 is attracted by the magnet 61 to assist in positioning and simplify the disassembly and assembly process. The filter 5 allows odor to be transferred between the first box 2 and the second box 3 on both sides, which improves the attraction effect of the bait and can effectively increase the enthusiasm of termites to cross the medicated soil.

[0032] Pull the top of the insertion rod 42 to make the slip ring 43 slide in the connecting box 41 and compress the spring 44. Then, align the two ends of the transparent tube 1 with the first box 2 and the second box 3 to ensure that the position of the insertion rod 42 matches the position of the first insertion hole 13 and the second insertion hole 14. Release the insertion rod 42, and the spring 44 will rebound and push the insertion rod 42 through the insertion hole in sequence, locking the transparent tube 1 and the first box 2 and the second box 3. After the bottom end of the insertion rod 42 passes through the second insertion hole 14, it presses against the pressure rod 7. Using the lever principle, the other end of the pressure rod 7 is forced to touch the filter screen 5 to ensure that the filter screen 5 is fastened. The spiral guide pattern guides the termites to migrate along the preset path, monitors the termite activity in real time, and records the behavioral data of penetrating the medicinal soil.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
