Description

Technical Field

[0001] This utility model relates to the field of agricultural plant protection equipment technology, specifically a measuring cup for quantitative root irrigation application of pesticides. Background Technology

[0002] In agricultural production, the application of pesticides is a crucial measure for controlling pests and diseases and ensuring crop yields. However, traditional pesticide application methods often suffer from inaccurate dosage. Farmers mostly rely on experience or simple tools to estimate the amount of pesticides needed, which may lead to insufficient pesticide use, resulting in ineffective pest and disease control, or excessive pesticide use, which not only increases costs but also pollutes the environment and may even cause food safety problems such as excessive pesticide residues in agricultural products.

[0003] While some existing pesticide application devices can achieve quantitative application to a certain extent, they are complex in structure and inconvenient to operate. For example, some electronic metering devices are expensive and easily damaged in field environments; some mechanical metering devices are cumbersome to adjust and difficult to quickly and accurately adjust the dosage according to actual conditions. Therefore, we propose a measuring cup for quantitative root irrigation application of pesticides. Utility Model Content

[0004] The purpose of this invention is to provide a measuring cup that is simple in structure, easy to use, and capable of accurately measuring pesticides, so as to solve the problem of inaccurate measurement in existing pesticide application methods, improve the efficiency and accuracy of pesticide application, and reduce pesticide waste and environmental pollution.

[0017] 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.

[0018] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a technical solution: a measuring cup for quantitative root irrigation of pesticides, including a cup body 1, a connecting cylinder 3 connected to the bottom of the cup body 1, and a water pipe 4 connected to the outside of the connecting cylinder 3. A connecting pipe 2 is installed on the outside of the cup body 1, and the end of the water pipe 4 is connected to the connecting pipe 2. A valve body 8 for controlling the opening and closing of the end of the water pipe 4 is provided inside the connecting cylinder 3, and a support rod 5 is fixedly connected inside the valve body 8. The end of the support rod 5 extends into the cup body 1, and a float ball 10 is installed on the outside of the end of the support rod 5 located inside the cup body 1.

[0019] It should be noted that the valve body 8 of the cup body 1 and the float 10 can be made of polyvinyl chloride (PVC) plastic. This material has good chemical stability, corrosion resistance and transparency, making it suitable for contact with pesticides and easy to observe the liquid level.

[0020] Please see Figure 2 The top of the connecting cylinder 3 is integrally provided with a connecting part 12, and the connecting part 12 is fixedly connected to the cup body 1. The bottom of the inner wall of the connecting part 12 is fixedly connected with an annular seat 6, and a positioning cylinder 7 is integrally provided in the center opening of the annular seat 6. The support rod 5 is slidably connected in the positioning cylinder 7, and a spring 9 is sleeved on the outside of the support rod 5 between the positioning cylinder 7 and the valve body 8.

[0021] It should be noted that when using the measuring cup of this utility model, firstly, the connecting tube 2 on the outside of the cup body 1 is connected to the pesticide spraying rod via a thread. During the process of injecting pesticide into the cup body 1, the amount of pesticide contained in the cup body 1 can be directly observed through the scale on the outside of the cup body 1. In the initial state, when the cup body 1 is empty, the valve body 8 is located at the bottom of the connecting cylinder 3 under the elastic force of the spring 9. At this time, the water pipe 4 is connected to the inside of the connecting cylinder 3, so that the pesticide in the pesticide tank is placed inside the cup body 1. After the pesticide enters the cup body 1, as the height of the pesticide rises, the float 10 floats with the surface of the pesticide. The buoyancy of float 10 is greater than the elastic force of spring 9, causing valve body 8 to rise. When float 10 reaches a certain height, valve body 8 blocks the opening between water pipe 4 and connecting cylinder 3, allowing the set amount of pesticide solution to enter the cup body 1. At this time, the pesticide solution in cup body 1 can be poured directly to the application site through the pesticide tank control lever. After the pesticide solution is applied to the roots, valve body 8 returns to the bottom position of connecting cylinder 3 under the action of spring 9. At this time, the pesticide solution enters cup body 1 again. After reaching the set amount, valve body 8 closes the opening between water pipe 4 and connecting cylinder 3 again, so that the amount of pesticide solution entering cup body 1 is consistent each time, achieving the purpose of quantitative and precise application of pesticides to the roots.

[0022] Please see Figure 1 The outer side of the cup body 1 is marked with a vertical scale to display the amount of pesticide inside the cup body 1.

[0023] It should be noted that the cup body 1 is made of transparent plastic material, which makes it easy to observe the pesticide liquid level. The scale on the cup body 1 makes it easy to know the amount of pesticide liquid that the cup body 1 can hold.

[0024] When manufacturing the cup body 1, a cup body 1 with a specific shape and capacity is produced through injection molding. The wall thickness of the cup body 1 should ensure sufficient strength and rigidity, while also considering cost and processing difficulty. Clear graduations are printed on the surface of the cup body 1. The graduation range should be reasonably determined according to the capacity of the measuring cup, for example, from 0 ml to 500 ml, with a graduation every 10 ml, to accurately measure the amount of pesticide. A standard threaded end is machined at the end of the connecting tube 2 on the outer side of the top of the cup body 1. The thread specification should match the common handheld connection part of the pesticide box to ensure smooth tightening.

[0025] Please see Figure 2 The support rod 5 is provided with an external thread on the outside of one end of the float 10, and the end of the support rod 5 with the external thread is threaded with a nut 11.

[0026] It should be noted that the nut 11 can be used to easily fix the float 10 to the support rod 5, and it also makes it easy to disassemble and replace the float 10.

[0027] Please see Figure 2 The end of the connecting tube 2 away from the cup body 1 is provided with an internal thread.

[0028] It should be noted that the port of the connecting pipe 2 is a threaded connection hole, which facilitates connection with the handheld pesticide handle of the pesticide box. This allows the pesticide solution inside the pesticide box to be placed in the connecting pipe 2 through the handheld pesticide handle, and then enter the water pipe 4 through the connecting pipe 2, until it enters the connecting cylinder 3 through the port of the water pipe 4. The internal thread at the end of the connecting pipe 2 can match the connection point of the handheld pesticide handle of the pesticide box, and can be tightened to fix it on the handheld pesticide handle by screwing it on, ensuring the sealing between the connecting pipe 2 and the handheld pesticide handle and preventing pesticide leakage.

[0029] Please see Figure 3 The float 10 is made of hollow plastic.

[0030] It should be noted that hollow plastic balls are used as floats 10. Hollow plastic balls have a low density and can provide sufficient buoyancy in pesticides. Polyethylene (PE) plastic can be used. It is lightweight and has moderate buoyancy, so that floats 10 can move up and down flexibly with the changes in the pesticide liquid level, thereby driving the support rod 5 and valve body 8 to control the opening and closing of the water pipe 4.

[0031] When manufacturing the float 10, it is made using a blow molding process to produce a hollow plastic ball of suitable diameter. The surface of the ball should be smooth and free of burrs to avoid affecting the float's floating performance. The valve body 8 can be manufactured by machining or injection molding. The valve body 8 should be equipped with a support rod 5 connected to the float 10 to ensure that the up-and-down movement of the float 10 can effectively control the opening and closing of the valve body 8. A spring 9 is selected so that the buoyancy of the float 10 is greater than the elastic force of the spring 9. The manufactured float 10, valve body 8 and spring 9 are assembled together and adjusted to ensure that the opening and closing action of the valve body 8 is flexible and reliable, and can accurately control the replenishment of pesticides according to changes in liquid level.

[0032] Please see Figure 2 and Figure 3 The height of valve body 8 is greater than the diameter of water pipe 4.

[0033] It should be noted that the height of the valve body 8 is set greater than the diameter of the water pipe 4 to ensure that the valve body 8 can completely close the end of the water pipe 4, preventing leakage when it is necessary to stop the flow of pesticides and ensuring the accuracy of quantitative control.
