Description

Technical Field

[0001] This utility model belongs to the field of farmland remediation technology, specifically relating to a uniform sprayer for foliar inhibitors on contaminated farmland. Background Technology

[0002] In my country, most soils exceeding pollutant standards are in a state of slight or mild pollution, and arable land generally falls into this category. Given the country's large population and limited land resources, coupled with immense pressure to meet agricultural demand, slightly or mildly polluted arable land still needs to undertake high-intensity agricultural production tasks. Under these circumstances, ensuring safe production on polluted arable land is crucial. Foliar control technology, as an effective means of controlling the absorption and translocation of heavy metals from crops to the aboveground parts, is of great significance. Foliar control agents are mainly applied through sprayers.

[0003] Existing foliar inhibitor sprayers for contaminated farmland have some obvious defects in actual use. On the one hand, the internal stirring device of the existing sprayers is relatively simple in design, and most of them can only achieve stirring in a single direction or with limited effect. They cannot make the liquid in the tank form an efficient composite flow field, which makes it difficult for the components in the liquid to be fully mixed evenly. Especially for some foliar inhibitors with complex components that are easy to precipitate or separate, the concentration of effective components in the liquid may be inconsistent between sprays, which seriously affects the protection and repair effect on crops.

[0004] On the other hand, existing sprayers lack effective measures to prevent pesticide particles from adhering to the inner walls of the device. As spraying progresses, a large number of pesticide particles gradually adhere to the inner walls of the pesticide tank. Prolonged adhesion of these particles not only wastes pesticide but also exacerbates the unevenness of the pesticide composition within the tank because they cannot return to the mixing center for further mixing. In subsequent spraying processes, the sprayed pesticide may contain a significant amount of components from these adhered particles, leading to excessively high pesticide concentrations in some areas of the crop, while other areas may fail to achieve the desired control effect due to insufficient active ingredients.

[0005] In summary, the existing foliar inhibitor sprayers for contaminated farmland have shortcomings in terms of mixing effect and prevention of adhesion to the inner wall, which seriously affect the spraying quality of foliar inhibitors and the treatment effect on contaminated farmland, and urgently need to be improved and innovated. Utility Model Content

[0006] The purpose of this invention is to provide a uniform sprayer for foliar control agents on contaminated farmland, which can form a composite flow field of main swirling flow and secondary breaking flow, greatly improving the uniformity of the agent mixing, so that the components of the control agent are fully mixed. At the same time, the agent particles adhering to the inner wall of the device can be scraped off during the mixing process to avoid the waste of residual components.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A uniform sprayer for foliar inhibitors on contaminated farmland includes a device body. A partition is fixed inside the device body near the top, dividing the interior of the device body into a pesticide tank and an installation tank. The pesticide tank is located at the bottom of the installation tank.

[0009] A water pump is installed on the outside of the device body. The input end of the water pump extends into the medicine tank of the device body through a hose. The output end of the water pump is fixed with a handle through a hose. An atomizing nozzle is provided at the end of the handle.

[0010] The medicine tank is rotatably connected to a main stirring paddle and a secondary stirring paddle, and the installation chamber is equipped with a drive mechanism.

[0011] The drive mechanism includes a rotating shaft rotatably connected inside the partition. A motor is installed inside the mounting chamber, and the output end of the motor is connected to the rotating shaft. The rotating shaft and the auxiliary stirring paddle are driven by a first transmission belt. A driven gear is installed on the outside of the main stirring paddle and inside the mounting chamber. A driving gear is meshed on the outside of the driven gear. A rotating block is fixed at the center of the driving gear and is rotatably connected to the partition. The auxiliary stirring paddle is connected to the rotating block by a second transmission belt.

[0012] The diameter of the driving gear is larger than the diameter of the driven gear.

[0013] A scraping plate is fixed to the bottom of the rotating shaft. The scraping plate is attached to the bottom end of the inner wall of the device body. A scraping side plate is fixed to the end of the scraping plate away from the rotating shaft, and the scraping side plate is attached to the inner wall of the device body.

[0014] A guide vane is fixed to one side of the scraping side plate, and the guide vane is set at an angle.

[0015] A protrusion is provided near the center of the scraping plate, at the position corresponding to the hose fixed at the water pump input end.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention, through the arrangement of a main stirring paddle and a secondary stirring paddle, can form a composite flow field of main swirling flow and secondary breaking flow, which greatly improves the uniformity of chemical mixing and ensures that all components of the control agent are fully mixed. At the same time, through the arrangement of scraping bottom plate and scraping side plate, the chemical particles adhering to the inner wall of the device can be scraped off during the mixing process, avoiding component residue and waste, and allowing them to flow back to the mixing center for secondary mixing. This effectively ensures that the concentration of the sprayed agent is consistent, significantly improving the effect of foliar control operations on contaminated farmland and the utilization rate of the agent.

Detailed Implementation

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-4As shown, a uniform sprayer for foliar inhibitors on contaminated farmland includes a device body 1. A partition 5 is fixed inside the device body 1 near the top, dividing the inside of the device body 1 into a liquid tank 6 and an installation tank 7. The liquid tank 6 is located at the bottom of the installation tank 7. An inlet is provided on the outside of the device body 1 at a position corresponding to the liquid tank 6. A sealing cap is provided on the inlet, so that after the user pours the medicine into the device body 1, the inlet is blocked by the sealing cap. The medicine can be a natural polymer inhibitor, a mineral-based inhibitor, a chelated inhibitor, or a synthetic polymer inhibitor.

[0026] A water pump 2 is installed on the outside of the device body 1. The input end of the water pump 2 extends into the medicine tank 6 of the device body 1 through a hose. The hose extends to the bottom of the medicine tank 6, which can fully absorb the medicine inside the device body 1. The output end of the water pump 2 is fixed to a handle 3 through a hose. The end of the handle 3 is equipped with an atomizing nozzle. A shoulder strap 4 is installed on one side of the device body 1. The user lifts the device body 1 by carrying the shoulder strap 4, and then starts the water pump 2, so that the water pump 2 can absorb the medicine inside the medicine tank 6 and deliver it into the handle 3, and spray it through the atomizing nozzle.

[0027] The main stirring paddle 9 and the auxiliary stirring paddle 10 are rotatably connected inside the medicine tank 6. The drive mechanism is installed inside the installation chamber 7. The drive mechanism drives the main stirring paddle 9 and the auxiliary stirring paddle 10 to rotate, thereby stirring the medicine inside the medicine tank 6.

[0028] See attached document Figure 3 The drive mechanism includes a rotating shaft 8 rotatably connected inside the partition 5. A motor 15 is installed inside the installation chamber 7. The output end of the motor 15 is connected to the rotating shaft 8. The rotating shaft 8 and the auxiliary stirring paddle 10 are driven by a first transmission belt 11. The auxiliary stirring paddle 10 and the rotating shaft 8 are equipped with transmission wheels, which are driven to rotate by the first transmission belt 11, so that the rotating shaft 8 and the auxiliary stirring paddle 10 rotate synchronously. A driven gear 14 is installed on the outside of the main stirring paddle 9 and inside the installation chamber 7. A driving gear 13 is meshed on the outside of the driven gear 14. A rotating block 20 is fixed at the center of the driving gear 13, and the rotating block 20 is rotatably connected to the partition 5. The auxiliary stirring paddle 10 and the rotating block 20 are connected by a second transmission belt 12. As above, the rotating block 20 and the auxiliary stirring paddle 10 are provided with corresponding transmission wheels. The second transmission belt 12 drives the transmission wheels to rotate, which in turn drives the auxiliary stirring paddle 10 to rotate the rotating block 20.

[0029] When driving the main stirring paddle 9 and the auxiliary stirring paddle 10 to rotate, the motor 15 can be driven, causing the output end of the motor 15 to drive the rotating shaft 8 to rotate. The rotating shaft 8, through the first transmission belt 11, can drive the auxiliary stirring paddle 10 to rotate. Furthermore, through the transmission of the second transmission belt 12, it drives the rotating block 20 and the driving gear 13 to rotate. Through the meshing connection between the driving gear 13 and the driven gear 14, the driving gear 13 can drive the driven gear 14 and the main stirring paddle 9 to rotate, thus driving the main stirring paddle 9 and the auxiliary stirring paddle 10 to rotate. This allows the main stirring paddle 9 to stir the liquid inside the medicine tank 6, forming a main swirling flow, while the auxiliary stirring paddle 10 forms a secondary breaking composite flow field, thereby achieving better stirring of the liquid inside the medicine tank 6. (See attached diagram.) Figure 3 The diameter of the driving gear 13 is larger than that of the driven gear 14. This arrangement causes the rotational speed of the main stirring paddle 9 to be greater than that of the driving gear 13, which in turn causes the rotational speed of the main stirring paddle 9 to be greater than that of the auxiliary stirring paddle 10. This results in the main stirring paddle 9 and the auxiliary stirring paddle 10 rotating at different speeds, causing the liquid inside the chemical tank 6 to form turbulence, ensuring the stirring effect and making the spraying effect more uniform. The device body 1 is equipped with a battery that can power the electrical components inside the device body 1.

[0030] See attached document Figure 4 A scraping plate 16 is fixed to the bottom of the rotating shaft 8. The scraping plate 16 is attached to the bottom end of the inner wall of the device body 1. A scraping side plate 17 is fixed to the end of the scraping plate 16 away from the rotating shaft 8, and the scraping side plate 17 is attached to the inner wall of the device body 1. When the rotating shaft 8 rotates, it can drive the scraping plate 16 to rotate, thereby allowing the scraping plate 16 to scrape the bottom end of the medicine tank 6. Through the setting of the scraping side plate 17, the scraping side plate 17 can scrape the side wall of the medicine tank 6, so that the medicine particles attached to the inner wall of the medicine tank 6 can be scraped off by the scraping plate 16 and the scraping side plate 17, avoiding To prevent poor mixing of the chemicals, a guide plate 18 is fixed to one side of the scraping side plate 17, and the guide plate 18 is set at an angle. The guide plate 18 can guide the chemicals scraped off by the scraping side plate 17, so that the chemicals can return to the swirling flow of the main stirring paddle 9 and the auxiliary stirring paddle 10. Furthermore, a protrusion 19 is provided near the middle of the scraping bottom plate 16 at the position corresponding to the hose fixed at the input end of the water pump 2. The protrusion 19 can prevent the hose from being blocked when the water pump 2 absorbs chemicals.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
