A device for testing the effectiveness of a pesticide in a partition

Abstract

This utility model relates to the agricultural field and discloses a pesticide effectiveness zoning test device. This utility model uses a limiting device to isolate two adjacent experimental planting areas by inserting a partition plate into the connection point. One side of the support plate on each side rests against the ground. Soil from the edge of the planting area can then be piled onto the support plate, forming a barrier on the ground. The partition plate separates the underground soil at the connection point. After the partition plate is inserted, the threaded rod can be manually turned, causing the abutment rod to slide downwards in the rectangular cavity. Several limiting rods slide outwards through sliding holes and are horizontally inserted into the soil, providing secondary limiting and fixing of the inserted partition plate. This prevents the partition plate from loosening or being pulled out if the soil becomes loose or is subjected to external force such as stones or plant roots during use, thus improving the isolation effect and ensuring the accuracy and reliability of the test data.

Description

Technical Field

[0001] This utility model relates to the agricultural field, and in particular to a pesticide effectiveness zoning test device. Background Technology

[0002] Pesticide effectiveness zoning test is a test method that divides the test area into different environmental zones to evaluate the control effects of different pesticides on crops and pests under different conditions.

[0003] In the process of conducting zoning tests on pesticide effectiveness, materials such as plastic film and wire mesh are usually buried directly between the test planting areas. However, due to the limited depth of these materials in the soil, they are unable to effectively prevent the lateral migration of pesticides in the soil with rainwater or irrigation water, leading to cross-contamination between different test areas and affecting the accuracy and reliability of the test data. Furthermore, in actual use, these materials are easily displaced or damaged by external forces such as stones and plant roots in the soil. Especially during severe weather such as heavy rainfall and strong winds, the loose soil can cause the materials to loosen or even be pulled out, making it impossible for them to maintain a stable isolation effect. Utility Model Content

[0004] The purpose of this invention is to provide a pesticide effectiveness zoning test device, which aims to solve the problems in the prior art.

[0005] This invention is implemented as follows: a pesticide effectiveness zoning test device includes a partition, the bottom longitudinal section of which is triangular, and a limiting device is provided on one side of the partition. The limiting device can limit and fix the partition a second time after it is inserted into the connection between two adjacent test planting sites.

[0006] Preferably, the limiting device includes two support plates, one side of which is inclinedly fixed to both sides of the partition. A circular groove is formed on one side of the partition, and a rectangular cavity is formed inside the partition. A threaded hole is formed on one side of the inner wall of the circular groove, with the inner wall of the threaded hole communicating with the inner wall of the rectangular cavity. Several sliding holes are formed on both sides of the inner wall of the rectangular cavity. Several limiting rods are provided, with the outer surface of each limiting rod slidably installed in the inner wall of the sliding hole. A spring is provided, with both ends of the spring fixedly installed on one side of the limiting rod and one side of the inner wall of the rectangular cavity, respectively. An abutment rod is provided, with one end slidably connected to the inner wall of the rectangular cavity, and both sides of the other end abutting against one side of several limiting rods, respectively. A threaded rod is inserted into the inner wall of the circular groove, with one end spirally penetrating the threaded hole and rotatably installed on one side of the abutment rod. A protective mechanism is provided on one side of the partition for blocking and sealing the entrance of the circular groove.

[0007] Preferably, the limiting device further includes a plurality of telescopic rods, wherein the outer surface of the telescopic rods is installed through the inner wall of the spring, and both ends are respectively fixedly installed on one side of the limiting rod and one side of the inner wall of the rectangular cavity.

[0008] Preferably, a plurality of round rods are rotatably mounted on both sides of one end of the abutment rod, wherein the outer surface of the round rods abuts against one side of the limiting rod.

[0009] Preferably, the protective mechanism includes a protective plate, wherein one side of the protective plate is rotatably mounted on one side of the partition, and the outer surface dimension of the protective plate is larger than the inner wall dimension of the circular groove.

[0010] Preferably, the protective mechanism further includes a rubber block, wherein the rubber block is fixedly installed on the side of the protective plate near the circular groove.

[0011] Preferably, splicing devices are provided on both sides of the partition. The splicing device includes a splicing block.

[0012] Preferably, the cross-section of the card block is T-shaped, and the cross-section of the card slot is T-shaped.

[0013] The beneficial effects of this utility model's disclosed pesticide effectiveness zoning test device are as follows: By setting a limiting device, during the pesticide effectiveness zoning test, a partition is inserted into the connection between two adjacent test planting areas to isolate them, so that one side of the support plate on both sides abuts the ground. Then, the soil at the edge of the planting area can be piled on the support plate to form a barrier on the ground. The partition can separate the underground soil at the connection point. In this way, when conducting experiments on two planting areas with different concentrations or different varieties of pesticides, the partition can effectively block them. After the partition is inserted, the threaded rod can be manually turned, rotating it a certain number of times in the circular groove and threaded hole, and then sliding it downwards. This causes the abutment rod to slide downwards in the rectangular cavity, abutting several limiting rods that slide outwards in the sliding holes and are inserted horizontally into the soil. At this time, the spring is in a contracted state, providing secondary limiting and fixing of the inserted partition. This prevents the partition from loosening and being pulled out if the soil becomes loose or is squeezed by stones or plant roots during use, thus improving the isolation effect and ensuring the accuracy and reliability of the test data.

[0022] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] In this embodiment:

[0024] Reference Figure 1-5 The diagram shows a preferred embodiment of the present invention.

[0025] This embodiment of a pesticide effectiveness zoning test device includes a partition 1. The bottom longitudinal section of the partition 1 is triangular. A limiting device 2 is provided on one side of the partition 1. The limiting device 2 can limit and fix the partition 1 a second time after it is inserted into the connection between two adjacent test planting sites.

[0026] Figure 1-5 The limiting device 2 shown includes two support plates 21, one side of which is inclinedly fixed to both sides of the partition 1. A circular groove 22 is formed on one side of the partition 1, and a rectangular cavity 24 is formed inside the partition 1. A threaded hole 23 is formed on one side of the inner wall of the circular groove 22, wherein the inner wall of the threaded hole 23 is connected to the inner wall of the rectangular cavity 24. Several sliding holes 25 are formed on both sides of the inner wall of the rectangular cavity 24; several limiting rods 29, wherein the outer surface of the limiting rods 29 is slidably installed in the inner wall of the sliding holes 25; and a spring 210, wherein the spring 21... The two ends of 0 are respectively fixedly installed on one side of the limiting rod 29 and one side of the inner wall of the rectangular cavity 24; the abutting rod 27, wherein one end of the abutting rod 27 is slidably connected to the inner wall of the rectangular cavity 24, and one end abuts against one side of several limiting rods 29 on both sides; the threaded rod 28, wherein the threaded rod 28 is inserted into the inner wall of the circular groove 22, and one end of the outer surface is spirally inserted through the threaded hole 23 and rotatably installed on one side of the abutting rod 27; the protective mechanism 26, wherein the protective mechanism 26 is set on one side of the partition plate 1, and is used to block and seal the entrance of the circular groove 22. By setting the limiting device 2, during the pesticide effectiveness zoning test, the partition 1 is inserted at the connection between two adjacent test planting areas to isolate them, so that one side of the support plate 21 on both sides abuts the ground. Then, the soil at the edge of the planting area can be piled on the support plate 21 to form a barrier on the ground. The partition 1 can separate the underground soil at the connection point. In this way, when conducting experiments on two planting areas with different concentrations or different varieties of pesticides, the partition 1 can effectively block them. After the partition 1 is inserted, it can be manually tightened. The threaded rod 28 is rotated a certain number of times in the circular groove 22 and threaded hole 23, and then slides downward, causing the abutment rod 27 to slide downward in the rectangular cavity 24. This abuts against several limiting rods 29, which slide outward in the sliding hole 25 and are inserted horizontally into the soil. At this time, the spring 210 is in a contracted state, which provides secondary limiting and fixing for the inserted partition 1. This ensures that if the soil becomes loose or is squeezed by external forces such as stones or plant roots during use, the partition 1 will not become loose or be pulled out, thus improving the isolation effect and ensuring the accuracy and reliability of the test data.

[0027] Figure 1-5The limiting device 2 shown also includes several telescopic rods 211, the outer surface of which is installed through the inner wall of the spring 210, and both ends are fixedly installed on one side of the limiting rod 29 and one side of the inner wall of the rectangular cavity 24, respectively. By setting the telescopic rods 211, the inner wall of the spring 210 can be supported and reinforced, making it less prone to damage during use and improving the service life of the spring 210. Several round rods 212 are rotatably installed on both sides of one end of the abutment rod 27, and the outer surface of the round rods 212 abuts against one side of the limiting rod 29. By setting the round rods 212, the abutment friction between one side of the abutment rod 27 and one side of the limiting rod 29 can be reduced, making it easier to push the limiting rod 29 out of the sliding hole 25 and insert it into the ground to perform secondary limiting and fixing of the partition 1 when the abutment rod 27 is pushed down.

[0028] Figure 1-5 The protective mechanism 26 shown includes a protective plate 261, one side of which is rotatably mounted on one side of the partition 1. The outer surface dimension of the protective plate 261 is larger than the inner wall dimension of the circular groove 22. By setting the protective mechanism 26, after adjusting the threaded rod 28, the protective plate 261 can be rotated to a certain angle to cover the circular groove 22. This completely encloses the threaded rod 28 inside the circular groove 22, reducing the contact area with the outside, lowering the probability of corrosion and rust, and increasing service life. The protective mechanism 26 also includes a rubber block 262, which is fixedly installed on the side of the protective plate 261 near the circular groove 22. By setting the rubber block 262, after the protective plate 261 completely covers the circular groove 22, the rubber block 262 can seal the gap between the protective plate 261 and the partition 1, making it difficult for moisture or impurities in the outside air to penetrate into the interior of the circular groove 22, thus reducing the probability of corrosion of the threaded rod 28.

[0029] Figure 1-5The partition 1 shown is provided with splicing devices 3 on both sides. The splicing device 3 includes splicing blocks 31. A locking block 33 is fixedly installed on one side of the splicing block 31 and one side of the partition 1. A slot 32 is opened on one side of the splicing block 31 and one end of the partition 1, wherein the locking block 33 is inserted into the inner wall of the slot 32. By setting up the splicing device 3, when using partitions 1 to separate two adjacent experimental planting areas, the locking block 33 on the splicing block 31 can be inserted into the slot 32 on one of the partitions 1, and then the locking block 33 on the adjacent partition 1 can be inserted into the slot 32 on the splicing block 31. This connects and fixes the two adjacent partitions 1 that are set at right angles, making them more secure during separation and facilitating their use in conjunction with the limiting device 2. Furthermore, if one partition 1 is insufficient for blocking, the locking block 33 on the first partition 1 can be inserted into the slot 32 on the second partition 1 to form a new size partition 1, extending the isolation distance and improving applicability. The cross-section of the locking block 33 and the slot 32 are both T-shaped. By arranging both the card block 33 and the card slot 32 in a T-shape, the connection between the two partitions 1 can be made more secure when the card block 33 is inserted into the card slot 32 for splicing, or the connection between it and the splicing block 31 can be made more secure and less prone to shaking.

[0030] Working principle: During the zoning test of pesticide effectiveness, partition 1 is inserted at the junction of two adjacent test planting plots to create a barrier. One side of the support plates 21 on both sides rests against the ground. Soil from the edge of the planting plot is then piled onto the support plates 21, forming a barrier on the ground. Partition 1 separates the underground soil at the junction. This allows for effective isolation when different concentrations or varieties of pesticides are tested on the two planting plots. After the partition 1 is installed, the screws can be manually tightened. The threaded rod 28 rotates a certain number of times in the circular groove 22 and the threaded hole 23, and then slides downwards, causing the abutment rod 27 to slide downwards in the rectangular cavity 24. This abuts against several limiting rods 29, which slide outwards in the sliding hole 25 and are inserted horizontally into the soil. At this time, the spring 210 is in a contracted state, which provides secondary limiting and fixing for the inserted partition 1. This ensures that if the soil becomes loose or is squeezed by external forces such as stones or plant roots during use, the partition 1 will not become loose or be pulled out, thus improving the isolation effect and ensuring the accuracy and reliability of the test data.

[0031] When using partition 1 to separate two adjacent experimental planting areas, the locking block 33 on the splicing block 31 can be inserted into the slot 32 on one of the partition 1, and then the locking block 33 on the adjacent partition 1 can be inserted into the slot 32 on the splicing block 31. This connects and fixes the two adjacent partitions 1 that are set at right angles, making them more secure when performing separation treatment and facilitating their use in conjunction with the limiting device 2. At the same time, if one partition 1 is not enough to block, the locking block 33 on the first partition 1 can be inserted into the slot 32 on the second partition 1 to form a new size partition 1, increasing the isolation distance and improving applicability.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
