Technical Field

[0001] The utility model relates to the field of agricultural medicine, in particular to a quantitative proportioning device for liquid medicine. Background Art

[0002] Wheat fields are farmlands specifically used to grow wheat or other grains. During the growth of wheat fields, weeds will compete for water, nutrients and sunlight, seriously affecting the growth and yield of crops. Therefore, wheat fields need to use herbicides to control the growth of weeds. Herbicides can effectively eliminate or reduce weeds in wheat fields, ensuring that wheat or other grains can obtain sufficient nutrients, water and sunlight, which is conducive to their normal growth and high yield.

[0003] Different types of plants have different sensitivities to the concentration of herbicides. Too low a concentration will not be able to effectively control weeds, while too high a concentration will have adverse effects on surrounding plants. However, traditional manual liquid medicine proportioning often relies on the experience and skills of the operator, and there are problems such as inaccurate proportioning and poor stability. Therefore, the utility model proposes a liquid medicine quantitative proportioning device. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0028] like Figure 1As shown, the utility model provides a technical solution: a quantitative proportioning device for liquid medicine, comprising a mixing tank 1, a proportioning component 2 is fixedly connected to the top of the mixing tank 1, a plurality of snap-fit ​​components 8 are slidably connected to the outside of the proportioning component 2, the proportioning component 2 comprises a proportioning tank, the bottom end of the proportioning tank is fixedly connected to the top of the mixing tank 1, a threaded rod 22 is threadedly connected to the top of the proportioning tank, a limiting block 23 is fixedly connected to the top of the proportioning tank, a piston 24 is fixedly connected to the bottom end of the threaded rod 22, a handle 25 is fixedly connected to the end of the threaded rod 22 away from the piston 24, the mixing tank 1 is a container for mixing liquid medicine, an observable scale plate is arranged on the outside, so as to facilitate observation of the inside of the proportioning tank 21, the proportioning component 2 is slidably connected to the plurality of snap-fit ​​components 8 on the outside, and this connection method is helpful to adjust and fix the proportioning component 2. By adjusting the clamping assembly 8, the position of the proportioning assembly 2 can be flexibly controlled, thereby achieving accurate proportioning of the liquid medicine. The proportioning tank is fixedly connected to the top of the mixing tank 1 and is a key component for controlling the flow rate of the liquid medicine. The top is threadedly connected to the threaded rod 22, so that the threaded rod 22 can adjust the depth of the proportioning tank by rotation, thereby accurately controlling the flow rate of the liquid medicine. The bottom is fixedly connected to a piston 24, and the piston 24 can move along the threaded rod 22 by rotating the threaded rod 22. The handle 25 is used for manual operation.

[0029] like Figure 3 As shown, the outer side of the threaded rod 22 is threadedly connected to the inner wall of the limit block 23, the outer side of the piston 24 is slidably connected to the inner wall of the proportioning tank, and the outer side of the piston 24 is slidably connected to each positioning block 82. The tight fit between the threaded rod 22 and the limit block 23 limits the rotation range of the threaded rod 22, thereby controlling the up and down movement range of the proportioning tank. The connection between the piston 24 and the inner wall of the proportioning tank can prevent the liquid medicine from leaking or overflowing from the side of the proportioning tank, thereby ensuring the safety and stability of the liquid medicine proportioning process and preventing the piston 24 from deflecting due to friction or instability.

[0030] like Figure 2 As shown, an electronic valve 6 is fixedly connected to one side of the proportioning tank away from the water pump 3, an end of the electronic valve 6 away from the proportioning tank is fixedly connected to a liquid outlet pipe 7, and an end of the liquid outlet pipe 7 away from the electronic valve 6 is fixedly connected to the mixing tank 1. After being controlled by the electronic valve 6, the liquid medicine flows from the proportioning tank to the mixing tank 1 through the liquid outlet pipe 7, and the fixed connection of the liquid outlet pipe 7 ensures the flow direction and flow stability of the liquid medicine. Example

[0031] like Figure 2 as well as Figure 4As shown, the clamping assembly 8 includes a slide plate 81, the outer side of the slide plate 81 is slidably connected to the inner wall of the proportioning tank, the side of the slide plate 81 close to the proportioning tank is fixedly connected to a positioning block 82, and the side of the slide plate 81 away from the positioning block 82 is fixedly connected to a pull ring 83. The clamping assembly 8 can be set according to specific needs. The spacing between each clamping assembly 8 is 50 mm for the clamping column or 100 mm for the mixing tank. The sliding connection between the slide plate 81 and the proportioning tank allows the slide plate 81 to slide smoothly along the inner wall of the proportioning tank. The position of the piston 24 can be adjusted by moving the slide plate 81. The fixed connection of the pull ring 83 allows the operator to conveniently move the slide plate 81 manually. Through the pull ring 83, the operator can easily adjust the position of the slide plate 81;

[0032] The side of the positioning block 82 close to the slide plate 81 is engaged with the inner wall of the proportioning tank, and the bottom end of the positioning block 82 is connected to the top end of the piston 24. The positioning block 82 is close to the side of the slide plate 81 and is engaged with the inner wall of the proportioning tank, ensuring a firm connection between the positioning block 82 and the proportioning tank to avoid affecting the normal movement of the piston 24. The positioning block 82 always maintains a fixed position during the proportioning process. Through contact with the piston 24, the positioning block 82 can ensure that the piston 24 can stop rotating upward through contact with the positioning plate when it moves in the proportioning tank, thereby improving the convenience of operation.

[0033] Working principle:

[0034] like Figure 1-4 As shown, first determine the required proportion, then slide the outer side of the slide plate 81 on the inner wall of the proportioning tank 21, the slide plate 81 can slide smoothly along the inner wall of the proportioning tank 21, and the operator can conveniently manually move the slide plate 81 through the pull ring 83 fixedly connected to the side of the slide plate 81 away from the positioning block 82. Through the operation of the pull ring 83, the position of the proportioning assembly 2 can be flexibly controlled, and the threaded rod 22 can be driven to rotate by the rotation of the handle 25. The threaded rod 22 is tightly matched with the inner wall of the limit block 23 through its outer thread, which limits the rotation range of the threaded rod 22, thereby controlling the up and down movement of the piston 24. When it moves to the position of the positioning block 82, it is restricted by the positioning block 82 and stops rotating. At this time, the water pump 3 is started, and the liquid medicine is sucked into the proportioning tank 21 through the liquid pipette 4. At the same time, the side of the proportioning tank away from the water pump 3 is fixedly connected with the electronic valve 6, and the electronic valve 6 controls the liquid medicine to flow from the proportioning tank to the mixing tank 1 through the liquid outlet pipe 7, and then flows out through the valve at the bottom.
