[0001] The utility model belongs to the technical field, and particularly relates to a quantitative mechanism for pesticide filling. Background Art

[0002] In agricultural production, pesticides are widely used. In order to ensure that pesticides can be accurately and efficiently applied to crops, pesticides need to be accurately filled. Traditional pesticide filling methods may have problems such as low precision and large errors. This will not only affect the use effect of pesticides, but may also lead to waste of resources or adverse consequences due to inaccurate dosage, such as insufficient efficacy or unnecessary impact on the environment. With the development of technology, the requirements for quantitative institutions are getting higher and higher. It needs to have high accuracy, stability and reliability. For example, it can adapt to pesticides of different viscosities and densities to ensure that the amount filled each time meets the standards.

[0003] However, during the use of existing pesticide filling quantitative mechanisms, when running for a long time or facing complex working conditions, inaccurate quantitative measurements may occur, resulting in large dosage deviations for some products, thereby reducing product consistency. Utility Model Content

[0004] The purpose of the utility model is to provide a quantitative mechanism for pesticide filling. By setting up a quantitative filling mechanism, the problem of inaccurate quantitative measurement that may occur during long-term operation or in complex working conditions is solved, resulting in large dosage deviations of some products, thereby reducing the consistency of the product.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a quantitative mechanism for pesticide filling, comprising a quantitative tube, on which a quantitative mechanism and a one-way flow component are arranged;

[0007] A drug inlet pipe is connected to the left outer wall of the metering tube, and a drug outlet pipe is connected to the right outer wall of the metering tube. The bottoms of the metering tube, the drug inlet pipe and the drug outlet pipe are fixedly connected to two supporting legs. The metering mechanism includes a metering component 1, a limit component and a metering component 2. The metering component 1 includes a threaded barrel rotatably passing through the metering tube, a threaded rod is threadedly passed through the inner wall of the threaded barrel, a piston 1 is slidably connected to the inner wall of the metering tube, and the front side of the piston 1 is rotatably connected to the threaded barrel.

[0008] Furthermore, a slide rod 1 is fixedly connected to the inner walls of the front and back sides of the quantitative tube, the slide rod 1 slides through the piston 1, and a gear 1 is fixedly connected to the outer wall of the threaded tube.

[0009] Furthermore, the position limiting assembly comprises a rotation groove provided on the quantitative tube, a clamping ring is fixedly connected to the outer wall of the threaded barrel, and the outer wall of the clamping ring is rotated to extend into the rotation groove.

[0010] Furthermore, the quantitative component 2 includes a rotating shaft rotatably connected to the front side of the quantitative tube, and a gear 2 is fixedly connected to the outer wall of the rotating shaft, and the gear 2 is meshed with the gear 1.

[0011] Furthermore, a motor is fixedly connected to the front side of the rotating shaft, a motor sleeve is fixedly connected to the outer wall of the motor, and a back side of the motor sleeve is fixedly connected to the quantitative tube.

[0012] Furthermore, the one-way flow component includes one-way flow component 1 and one-way flow component 2, the one-way flow component 1 includes an adapter ring fixedly connected to the inner walls of the drug inlet pipe and the drug outlet pipe respectively, and the inner walls of the drug inlet pipe and the drug outlet pipe are fixedly connected with a cross support frame.

[0013] Furthermore, piston 2 is fixedly connected to the inner walls of the two adapter rings, and sliding rod 2 is fixedly connected to the sides of the two pistons away from each other. The sides of the two sliding rods away from piston 2 slide through the outer walls of the two cross support frames and extend to the outside.

[0014] Furthermore, the one-way circulation component 2 includes limit plates respectively fixedly connected to the sides of the two sliding rods 2 that are away from each other, and springs are sleeved on the two sliding rods 2.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting a quantitative mechanism, when the drug inlet pipe and the drug outlet pipe of the device are connected to the drug source and the container respectively, the motor on the motor sleeve is started, and the motor drives the second gear to rotate through the rotating shaft, and the second gear drives the threaded barrel to rotate through the first gear, thereby driving the threaded rod to rotate, so that the piston 1 on the threaded rod slides backward under the action of the sliding rod 1, and the pesticide from the pesticide source is drawn into the quantitative pipe through the drug inlet pipe, so that the required dosage can be drawn from the original pesticide storage container with high precision, ensuring that the amount of pesticide in each container is accurate, avoiding problems caused by excessive or insufficient use, and ensuring that each container gets the correct dosage without wasting pesticides or causing excessive use;

[0017] 2. By setting a one-way flow mechanism, when the device extracts pesticides, the second piston on the adapter ring in the medicine inlet pipe moves to the right under the action of the negative pressure in the quantitative tube, thereby pushing the limit plate to move to the right and compressing the spring. At this time, the pesticide enters the quantitative tube through the gap between the second piston and the adapter ring, so that the accuracy of the pesticide flow can be ensured. Since the pesticide can only flow in one direction, the flow control is more precise, avoiding flow fluctuations and waste caused by uneven pesticide flow or pipeline blockage. When the pressure inside the container is higher than that outside, the one-way flow mechanism only allows the pesticide to flow to the target container, and will not flow back from the target container to the large container, which can avoid cross contamination and waste of pesticides.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] By setting a slide bar 214, the threaded rod 212 is rotated, so that the piston 213 on the threaded rod 212 slides backward under the action of the slide bar 214, and the pesticide from the pesticide source is drawn into the quantitative tube 1 through the drug inlet tube 101.

[0043] By providing the one-way flow component 2 32, the accuracy of the pesticide flow can be ensured. Since the pesticide can only flow in one direction, the flow control is more precise, avoiding flow fluctuations and waste caused by uneven pesticide flow or pipeline blockage.

[0044] A specific application of this embodiment is as follows: when in use, firstly, the device is stably placed at a corresponding position through the support legs 103, the medicine inlet pipe 101 is connected to the pesticide source, the medicine outlet pipe 102 is connected to the container to be filled, and the motor 233 on the motor sleeve 234 is started. The motor 233 drives the gear 232 to rotate through the rotating shaft 231, and the gear 232 drives the threaded cylinder 211 to rotate through the gear 1 215, thereby driving the threaded rod 212 to rotate, so that the piston 1 213 on the threaded rod 212 slides backward under the action of the slide rod 1 214, and the pesticide from the pesticide source is drawn into the quantitative tube 1 through the medicine inlet pipe 101, so that the required dosage can be extracted from the original pesticide storage container with high precision, ensuring that the amount of pesticide in each container is accurate, avoiding problems caused by excessive or insufficient use, and ensuring that each container gets the correct dosage without wasting pesticides or causing excessive use. When the device extracts pesticides, the piston 2 313 on the adapter ring 311 in the medicine inlet pipe 101 will move to the right under the action of the negative pressure in the quantitative tube 1, thereby pushing the limit plate 321 to move to the right and compressing the spring 322. At this time, the pesticide enters the quantitative tube 1 through the gap between the piston 2 313 and the adapter ring 311, so that the accuracy of the pesticide flow rate can be ensured. Since the pesticide can only flow in one direction, the flow control is more precise, avoiding flow fluctuations and waste caused by uneven pesticide flow or pipeline blockage. When the pressure inside the container is higher than that outside, the one-way flow mechanism only allows the pesticide to flow to the target container, and will not flow back from the target container to the large container, so as to avoid cross contamination and waste of pesticides. After the pesticide in the quantitative tube 1 is full, the motor 233 is started again to make the motor 233 rotate in the opposite direction, and the pesticide in the quantitative tube 1 is pushed into the container through the medicine outlet pipe 102.
