Description

Technical Field

[0001] The utility model belongs to the technical field of agriculture. Specifically, it particularly relates to a measuring tool for measuring the persistent foaming property of pesticides. Background Art

[0002] To ensure the crop yield, during the growth period of crops, people put pesticides and water into a container and then stir them. A large number of water bubbles will be generated during the stirring process, making it impossible for people to confirm the amount of pesticides in the container, resulting in the pesticides often being prepared too much or too little, which has an impact on the crops. According to the national standard GB / T 28137-2011 Determination Method for Persistent Foaming Property of Pesticides, this standard is applicable to pesticide products that need to be diluted with water before application, and there are strict requirements for the amount of foam generated after mixing and stirring pesticides and water in this standard.

[0003] In the existing technology for measuring the persistent foaming property according to GB / T 28137-2011, when the foam exceeds the 250 mL scale line, usually according to the requirements in 3.5.2, a scale is used to measure the height above the scale line for estimation, but the estimation result is not accurate enough. Summary of the Utility Model

[0004] Aiming at the problems in the related technology, the utility model provides a measuring tool for measuring the persistent foaming property of pesticides to overcome the above-mentioned technical problems existing in the existing related technology.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a measuring tool for measuring the persistent foaming property of pesticides, including a measuring component and a graduated cylinder with a stopper. The measuring component includes a fixed plate, a moving plate, a marking plate, and a handle. On both sides of the fixed plate, limiting grooves are symmetrically opened. The limiting grooves are located on one side of the midline of the fixed plate. A moving groove is opened on the moving plate. The moving groove is in a "匚" shape in the middle of the moving plate. The moving plate is installed on the fixed plate through the moving groove. A slider is arranged inside the moving groove. The slider corresponds to the limiting groove and is located in the limiting groove.

[0007] Further, an installation hole is opened on one side of the moving plate. The installation hole is located in the middle of the moving plate and penetrates through one side of the moving plate and communicates with the moving groove. An indicating needle is arranged on one side of the moving plate. The lower side of the indicating needle is flush with the lower side of the moving plate. The indicating needle is located on one side of the moving groove.

[0008] Further, a fixing bolt is installed in the installation hole. The fixing bolt fits with the installation hole. A rotating knob is installed at the upper end of the fixing bolt. The moving plate is fixed on the fixed plate through the fixing bolt.

[0009] Furthermore, a ruler is provided on the fixed plate, the ruler and the indicator needle are perpendicular to each other, a marking plate is provided on the fixed plate, the marking plate is located at the lower end of the ruler, the marking plate and the indicator needle are parallel to each other, and the zero scale of the ruler coincides with the top of the marking plate.

[0010] Furthermore, a handle is connected to the lower end of the fixing plate, and the handle is located directly below the marking plate.

[0011] Furthermore, an elastic clip is provided on the fixing plate.

[0012] Furthermore, a rubber pad is provided on the inner side of the elastic clip.

[0013] Furthermore, the stoppered measuring cylinder fits with the elastic clip, the stoppered measuring cylinder is provided with a stopper, the graduation value of the stoppered measuring cylinder is 2mL, the 0-250mL scale lines are 20cm-21.5cm apart, and the bottom of the stopper is 4cm-6cm away from the 250mL scale line of the stoppered measuring cylinder (the same as 3.3 in GB / T 28137-2011).

[0014] The utility model has the following beneficial effects: by using a measuring tool for measuring the persistent foaming property of pesticides, the operation is first performed according to the specification of GB / T 28137-2011 for measuring the persistent foaming property, and when the foam exceeds the 250mL scale line, the measuring component is used for measurement, and the upper end of the marking plate is first aligned with the bottom of the foam to make it the bottom position of the foam, and then the elastic clamp is used to clamp the stopper measuring cylinder, so that the measuring component is fixed on the stopper measuring cylinder, and the rubber pad on the elastic clamp not only protects the stopper measuring cylinder to prevent the stopper measuring cylinder from being worn during the clamping process, but also increases the friction, so that the elastic clamp clamps the stopper measuring cylinder more tightly, and after determining the bottom position of the foam and fixing the measuring component, the fixing bolt is loosened by rotating the knob, so that the movable plate can move on the fixing plate, and then the movable plate is moved to make the lower end of the indicating needle move to the highest position of the foam, and then the fixing bolt is tightened by rotating the knob again. The bolt is tightened to fix the movable plate. During this process, the movable plate can only make linear movements in the up and down directions with the cooperation of the limit groove and the slider, and the indicator needle is kept horizontal. After determining the position of the indicator needle, the measuring component can be removed from the stoppered measuring cylinder.

The data is then compared with the scale line of the stoppered measuring cylinder to read the specific value to obtain the volume of the foam. Through the precise measurement of the measuring component, the large error between the estimated value after measuring the foam height with a ruler and the actual value is avoided, so that the obtained result is more accurate. Through the simple structural design, the tool is very simple to operate, and there are no restrictions on the operator, making the tool more applicable.
