Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to an adjustable bracket used for pesticide field efficacy tests. Background Art

[0002] The field efficacy test of pesticides is a test of the effect of pesticides on harmful organisms in the field. It is a very important method to determine whether new pesticide varieties can be widely promoted and applied in agricultural production. Field efficacy tests can be divided into small areas, large areas and large-scale demonstrations. This is a study and comparison of several different pesticides under natural conditions, using several different immediate conditions and requirements to identify the most effective and economically effective pesticide varieties, and at the same time determine their field use scope, control targets, minimum effective dosage, concentration and other technical conditions. Generally, pesticides that have been proven to be effective through indoor experiments must first be tested in small areas, and projects with better test results must then be tested in large areas. Before formal promotion, large-scale demonstrations are often required to gain extensive experience. Therefore, field testing of pesticides is a task that must be done before pesticides become commodities.

[0003] In order to facilitate subsequent management and observation, it is necessary to set up a bracket in the field to facilitate the installation of functional equipment, such as cameras and fill lights. The existing bracket structure is relatively simple, and most of them are fixed structures, which cannot be adjusted down according to the size of the test field. There are also adjustable brackets in the prior art. For example, the utility model with publication number CN218570976U records a retractable greenhouse bracket for agricultural planting, including six sleeves, and the upper sides of the six sleeves are fixedly connected to a linkage box. Through the provided rotating disk, the adjusting rotating rod is inserted into the cross hole provided on the rotating disk, and then the adjusting rotating rod is rotated to make the rotating disk drive the first gear to rotate through the first rotating rod, and the first gear is connected to the first tooth groove provided on the cylindrical fixing rod through meshing, so as to achieve the effect of moving the cylindrical fixing rod to the front and rear sides. The height and width can be adjusted through this device, but the length adjustment and convenient disassembly and assembly process cannot be achieved. In addition, when functional equipment needs to be installed, the functional equipment cannot be moved, so that the entire test field cannot be observed and managed. In order to overcome this technical problem, the utility model provides an adjustable bracket for pesticide field efficacy test. Utility Model Content
