Description

Technical Field

[0001] This invention relates to the field of agricultural pest control technology, specifically to an automatic pesticide dispensing and spraying device with multiple pesticide tanks. Background Technology

[0002] In agricultural production, automated crop spraying devices are increasingly used to achieve precise crop care and pest control. One existing automated crop spraying device uses advanced image recognition technology to determine the cause of crop diseases, and then selects and sprays the appropriate pesticides, which improves the efficiency and scientific nature of agricultural production to some extent. However, this device faces some significant technical challenges in practical application. First, to meet the needs of different pesticide formulations for different diseases, the device contains multiple independent containers holding pre-mixed pesticides. This results in a complex overall structure and a large footprint, increasing manufacturing costs and limiting its application in small farmlands or complex terrain.

[0003] Secondly, while the multiple mixing chambers are designed for precise pesticide application, in practice, due to factors such as the structure of the mixing chambers and the stirring method, pesticide mixing is often insufficient. This can lead to uneven pesticide concentration, affecting the spraying effect, failing to effectively treat the crop's disease, and even potentially damaging the crop due to excessively high local pesticide concentrations. Furthermore, pesticide residue often remains in the mixing chambers after spraying. This residue not only wastes pesticide but may also affect the accuracy of subsequent pesticide application and spraying effectiveness due to spoilage or cross-contamination. In conclusion, while existing automatic crop spraying devices based on image recognition of crop disease causes offer certain advantages in terms of intelligence and precision, their internal structure and operating methods still present significant technical challenges in areas such as space utilization, mixing efficiency, and residue handling.

The first airflow inlet and the first liquid outlet are both connected to the first stirring space. The first liquid outlet leads to the total liquid outlet. The first sliding member is configured to compress or cancel the compression of the first stirring space after sliding up and down.

[0012] As a further technical solution, it also includes:

[0013] A drug delivery tube, one end of which is connected to the drug liquid chamber, and the other end of which is disposed on the first sliding member and passes through the first sliding member to communicate with the first stirring space;

[0014] An electrically controlled valve is installed on the drug delivery tube. There are several electrically controlled valves, and each drug delivery tube is equipped with an electrically controlled valve.

[0015] As a further technical solution, the bottom support has a concave arc bottom groove, the edge of the bottom support is the lowest point of the concave arc bottom groove, and the first liquid outlet is located on one side of the concave arc bottom groove.

[0016] As a further technical solution, it also includes:

[0017] The first blade is rotatably disposed within the first stirring space. The first blade is always in sliding contact with the bottom wall of the concave arc bottom groove, and the upper and lower ends of the first blade are respectively in harmony with the top of the concave arc bottom groove and the bottom of the first sliding member. The first blade is configured such that after the first sliding member descends and slides, the upper and lower ends of the first blade are in sliding contact with the first sliding member and the concave arc bottom groove, respectively.

[0018] As a further technical solution, the first gas flow inlet is located above the first liquid flow outlet, and further includes:

[0019] The second sliding member is slidably disposed in the second inner cavity, and the second sliding member moves up and down synchronously with the first sliding member.

[0027] The working principle and beneficial effects of this invention are as follows:

[0028] In this invention, when medication needs to be prepared, external airflow enters the first inner cavity through the first airflow inlet. The first sliding member moves up and down under the action of the driving device. When the first sliding member descends, it compresses the first inner cavity, at which point the liquid medication and airflow are fully mixed under pressure. Subsequently, the first sliding member continues to descend, completely squeezing out the mixed liquid medication, which flows through the first liquid outlet to the main liquid outlet, achieving a complete medication preparation and spraying action. Introducing air and utilizing the sliding member to compress the cavity allows for thorough mixing and complete drainage of the liquid medication within a single cavity, avoiding the structural complexity and space occupation problems associated with multiple cavities, making the device more concise and compact. This unique mixing and drainage method ensures the accuracy and consistency of each medication preparation, reduces liquid medication residue and waste, and improves the utilization rate of the liquid medication. The simple structural design reduces equipment costs and manufacturing difficulty, while also reducing the possibility of malfunctions and facilitating maintenance. The air intake and the movement parameters of the sliding member can be flexibly adjusted according to different liquid medication formulations and spraying requirements, making it highly adaptable.

[0039] Reference Figures 1-4 An embodiment of the present invention provides an automatic dispensing and spraying device with multiple medicine tanks, comprising an outer shell 1, the bottom of which has a main liquid outlet 101 communicating with the outside; an inner shell 2 disposed inside the outer shell 1, the inner shell 2 having a first inner cavity 201, and a second inner cavity 202 formed between the outer shell 1 and the inner shell 2, the first inner cavity 201 having a first airflow inlet 203 and a first liquid outlet 204, the first airflow inlet 203 communicating with the outside; and a plurality of medicine bottles 3 arranged in the outer shell 1. On the outer wall, the medicine bottle 3 has a medicine cavity 301, which leads to the first inner cavity 201; the bottom support 4 is disposed in the first inner cavity 201; the first sliding member 5 is slidably disposed in the first inner cavity 201, and a first stirring space 501 is formed between the first sliding member 5 and the bottom support 4. The first airflow inlet 203 and the first liquid outlet 204 are both connected to the first stirring space 501, and the first liquid outlet 204 leads to the main liquid outlet 101. The first sliding member 5 is configured to compress or cancel the compression of the first stirring space 501 after sliding up and down.

[0040] In this embodiment, the outer shell 1 is a hollow cylindrical structure with a main liquid outlet 101 at its bottom. The inner shell 2 is also cylindrical and is installed inside the outer shell 1, forming an annular second inner cavity 202 between the two. Multiple medicine bottles 3 are evenly arranged circumferentially on the outer wall of the outer shell 1, and each medicine bottle 3 has a medicine cavity 301 inside. The bottom support 4 is fixed to the bottom of the first inner cavity 201 of the inner shell 2, and the first sliding member 5 slides in cooperation with the inner wall of the first inner cavity 201. First, different medicines are injected into the medicine cavities 301 of each medicine bottle 3. When medicine needs to be prepared, external airflow enters the first inner cavity 201 through the first airflow inlet 203. The first sliding member 5 slides up and down under the action of the driving device. When the first sliding member 5 descends, it compresses the first inner cavity 201, at which time the medicine and airflow are fully mixed under pressure. Subsequently, the first sliding member 5 continues to descend, completely squeezing out the mixed liquid, which flows through the first liquid outlet 204 to the main liquid outlet 101, completing one batch of dispensing and spraying. Introducing air and utilizing the sliding member to squeeze the chamber allows for thorough mixing and complete drainage of the liquid within a single chamber, avoiding the structural complexity and space constraints of multiple chambers, making the device more concise and compact. This unique mixing and drainage method ensures the accuracy and consistency of each dispensing, reduces liquid residue and waste, and improves liquid utilization. The simple structural design reduces equipment costs and manufacturing difficulty, while also reducing the likelihood of malfunctions and facilitating maintenance. The air intake and sliding member movement parameters can be flexibly adjusted according to different liquid formulations and spraying requirements, making it highly adaptable.

[0041] Furthermore, it also includes a drug delivery tube 6, one end of which is connected to the liquid medicine chamber 301, and the other end is disposed on the first sliding member 5 and passes through the first sliding member 5 to communicate with the first stirring space 501; an electric control valve 7 is disposed on the drug delivery tube 6, and there are several electric control valves 7, with each drug delivery tube 6 being provided with an electric control valve 7.

[0042] In this embodiment, the delivery tube 6 is a long and thin pipe, one end of which is connected to the liquid chamber 301 of the liquid bottle 3, and the other end passes through the first sliding member 5 and is connected to the first stirring space 501. Each delivery tube 6 is equipped with an electrically controlled valve 7. After the image recognition system determines the type of crop disease, the control system determines the type of liquid to be extracted according to the preset formula. When a certain liquid needs to be extracted, the corresponding electrically controlled valve 7 opens. At this time, as the first sliding member 5 moves upward, a negative pressure is generated in the first stirring space 501, and the liquid is drawn from the liquid chamber 301 into the first stirring space 501 through the delivery tube 6. When a certain type of liquid does not need to be extracted, the corresponding electrically controlled valve 7 remains closed, and the liquid will not be extracted. The extraction method of generating negative pressure by moving the first sliding member upward is simple in structure and stable in operation, and can accurately extract the required amount of liquid. The precise control of the electrically controlled valve avoids unwanted liquid mixing, ensuring the accuracy and purity of the liquid formula. It can quickly respond to changes in crop diseases and adjust the pesticide application plan in a timely manner, improving operational efficiency and flexibility. It reduces errors caused by human judgment and operation, improving the reliability and consistency of pesticide application. It effectively utilizes equipment space, realizing an intelligent and automated pesticide application process, reducing labor intensity and costs.

[0043] Furthermore, the bottom support 4 has a concave arc bottom groove 401, the edge of the bottom support 4 is the lowest point of the concave arc bottom groove 401, and the first liquid outlet 204 is located on one side of the concave arc bottom groove 401.

[0044] In this embodiment, the base support 4 is disc-shaped, with its central part being the highest and its edges concave to form a concave arc groove 401. The first liquid outlet 204 is located on one side of the concave arc groove 401. During the preparation and stirring process, the mixed liquid naturally flows to the concave arc groove 401 at the edge of the base support 4 due to gravity. When the first sliding member 5 is squeezed, the liquid can flow quickly and concentratedly along the concave arc groove 401 to the first liquid outlet 204, thus being smoothly discharged for spraying. The design of the high central part and concave edge of the base support 4 more effectively guides the liquid to converge towards the edge, allowing the liquid to flow more quickly and concentratedly to the first liquid outlet 204, significantly improving the discharge efficiency. The concave arc groove 401 with its concave edge can minimize the residue of the liquid on the base support 4, ensuring that the liquid is fully discharged and maximizing the utilization rate of the liquid. This helps to ensure that the discharge volume of the liquid is stable and consistent after each preparation, further improving the accuracy and effect of preparation and spraying. This reduces the accumulation of the drug solution inside the device, lowers the possibility of drug deterioration and cross-contamination, and ensures the quality and efficacy of the drug solution.

[0045] Furthermore, it also includes a first blade 8, which is rotatably disposed within the first stirring space 501. The first blade 8 is always in sliding contact with the bottom wall of the concave arc bottom groove 401, and the upper and lower ends of the first blade 8 are respectively matched with the top of the concave arc bottom groove 401 and the bottom of the first sliding member 5. The first blade 8 is configured such that after the first sliding member 5 slides down, the upper and lower ends of the first blade 8 are in sliding contact with the first sliding member 5 and the concave arc bottom groove 401, respectively.

[0046] In this embodiment, a first blade 8 is added to the multi-tank automatic dispensing and spraying device. When the first sliding member 5 descends, it pushes the first blade 8 to rotate, and simultaneously, the upper and lower ends of the first blade 8 slide tightly against the first sliding member 5 and the concave arc bottom groove 401, respectively. When the first sliding member 5 rises, the first blade 8 rotates in the opposite direction under the action of the liquid medicine and airflow. The rotation of the first blade 8 can further enhance the mixing effect of the liquid medicine and airflow, making the liquid medicine mixture more uniform and thorough. The tight sliding contact with the first sliding member 5 and the concave arc bottom groove 401 reduces leakage and residue of the liquid medicine during the stirring process, and improves the utilization rate of the liquid medicine. It can promote the flow of the liquid medicine in the first stirring space 501 and avoid local uneven mixing. It can also scrape the inner wall in real time.

[0047] Furthermore, the first airflow inlet 203 is located above the first liquid outlet 204 and also includes a second sliding member 9. The second sliding member 9 is slidably disposed in the second inner cavity 202, and the second sliding member 9 moves up and down synchronously with the first sliding member 5. The second sliding member 9 is configured to block or unblock the first airflow inlet 203 or the first liquid outlet 204 after moving up and down.

[0048] In this embodiment, during operation, the first sliding member 5 and the second sliding member 9 rise synchronously. Since the first airflow inlet 203 is located above the first liquid outlet 204, gas is initially drawn in from the first airflow inlet 203 during the initial rise, causing a certain amount of gas to be stored in the first stirring space 501. Subsequently, the second sliding member 9 slides to block the first airflow inlet 203. The side of the second sliding member 9 close to the inner shell 2 has a baffle, which is tightly attached to the inner shell 2, thus forming a closed state in the first stirring space 501. As the first sliding member 5 rises, the baffle of the second sliding member 9 continues to slide on the outer wall of the inner shell 2, maintaining the dimensional closed state of the first stirring space 501. The first sliding member 5 and the second sliding member 9 continue to slide upwards, the negative pressure continues to decrease, and the liquid medicine is drawn into the first stirring space 501 from the liquid medicine chamber 301 through the delivery tube 6 and leaks out of the first liquid outlet 204. After the injection is completed, due to the presence of air, the liquid level in the first stirring space 501 is lower than the spatial height of the first stirring space 501. Next, the first sliding member 5 and the second sliding member 9 slide down to apply pressure. During this downward pressure, the first sliding member 5 pumps the mixed medicine solution into the next chamber. Continuing to pressurize, all remaining medicine solution and excess liquid in the first stirring space 501 are discharged. Afterward, the second sliding member 9 seals the lower section of the pressurized second inner chamber 202. This sequence of actions—first drawing in air to create negative pressure, then drawing in liquid, and finally pressurizing and discharging—allows for precise control of the amount of medicine drawn in and discharged, ensuring the accuracy and stability of the dispensing process. It effectively utilizes spatial relationships, achieving a continuous process of gas drawing in, medicine drawing in, mixing and pressurizing, and discharging through the rational movement of the sliding members, thus improving work efficiency. The negative pressure method ensures sufficient medicine drawing in, avoiding residue and waste, and improving medicine utilization. Multiple pressurization and discharging processes maximize the discharge of medicine solution from the first stirring space 501, reducing medicine accumulation and lowering the risk of medicine deterioration and cross-contamination.

[0049] Furthermore, the second inner cavity 202 is an annular cavity, and the bottom has a frustum-shaped section 205, the diameter of which gradually decreases toward the main liquid outlet 101.

[0050] In this embodiment, as the liquid medicine flows from the first inner cavity 201 to the main liquid outlet 101, when it passes through the frustum-shaped section 205 of the second inner cavity 202, the flow velocity of the liquid medicine gradually increases due to the gradually decreasing diameter, thus allowing it to flow more smoothly to the main liquid outlet 101. The design of the frustum-shaped section 205 can guide the flow, accelerate the flow speed of the liquid medicine, improve the drainage efficiency, and reduce the residence time of the liquid medicine in the device. This helps to ensure the continuous and stable discharge of the liquid medicine, avoid blockages or poor flow, and improve the reliability of the device. The gradually decreasing diameter can generate a certain pressure difference, promote the discharge of the liquid medicine, reduce dependence on external power, and save energy.

[0051] Furthermore, it also includes a second blade 10, which is rotatably disposed within the frustum-shaped section 205. The second blade 10 maintains sliding contact with both the inner wall of the frustum-shaped section 205 and the bottom wall of the inner shell 2.

[0052] In this embodiment, when the liquid medicine flows through the frustum-shaped section 205, it drives the second blade 10 to rotate. The rotation of the second blade 10 further promotes the flow of the liquid medicine, allowing it to flow more smoothly to the main liquid outlet 101. The rotation of the second blade 10 enhances the flow dynamics of the liquid medicine, accelerates the discharge speed, and improves working efficiency. The sliding contact with the inner wall of the frustum-shaped section 205 and the bottom wall of the inner shell 2 reduces leakage and residue of the liquid medicine during the flow process, improving the utilization rate of the liquid medicine. It further promotes the mixing and uniform distribution of the liquid medicine, ensuring the consistency of the liquid medicine composition. It increases the stability of the liquid medicine flow, reduces the generation of turbulence and vortices, and is conducive to precise control of the discharge volume of the liquid medicine.

[0053] Furthermore, it also includes a main shaft 11, which rotates through the outer shell 1, the inner shell 2, the bottom support 4 and the first sliding member 5. The first blade 8 and the second blade 10 are disposed on the main shaft 11, and the main shaft 11 is threadedly connected to the first sliding member 5.

[0054] In this embodiment, when the first sliding member 5 moves up and down, its threaded connection with the main shaft 11 causes the main shaft 11 to rotate. The rotation of the main shaft 11 further drives the first blade 8 and the second blade 10 to rotate, thus playing a role in the mixing and flow of the medicinal liquid. By using the sliding of the first sliding member 5 to drive the rotation of the main shaft 11, the linkage of component actions is achieved, reducing the need for additional drive devices and simplifying the equipment structure and control process. The rotation of the main shaft 11 drives the blades to rotate, enhancing the stirring and flow effect of the medicinal liquid, making the mixing more uniform and the flow smoother. The threaded connection ensures stable and reliable transmission between the first sliding member 5 and the main shaft 11, enabling precise control of the blade rotation speed and angle.

[0055] Furthermore, both the first blade 8 and the second blade 10 are arranged in several circles and are tilted.

[0056] In this embodiment, during equipment operation, as the main shaft 11 rotates and the liquid medicine flows, multiple inclined first blades 8 and second blades 10 simultaneously function to stir and propel the liquid medicine. The several circumferentially arranged blades can act on the liquid medicine over a wider range, improving the efficiency and uniformity of stirring and flow. The inclined blades generate axial and radial thrust during rotation, enhancing the mixing effect and flow rate of the liquid medicine. The uniformly arranged and inclined blade design makes the forces acting on the liquid medicine within the device more balanced, reducing local eddies and stagnation. This increases the contact area and contact time between the blades and the liquid medicine, further improving the mixing quality and discharge stability of the liquid medicine.

[0057] Furthermore, the first airflow inlet 203 and the first liquid outlet 204 are both arranged in several circles on the inner shell 2.

[0058] In this embodiment, during device operation, multiple first airflow inlets 203 simultaneously introduce air, allowing the gas to enter the first stirring space 501 more evenly and mix thoroughly with the liquid medicine. Multiple first liquid outlets 204 simultaneously discharge liquid, ensuring smooth and uniform discharge of the liquid medicine. The circumferentially arranged multiple airflow inlets and liquid outlets enable a more uniform distribution of gas and liquid medicine within the first stirring space, improving mixing efficiency and discharge efficiency. Increasing the number of airflow and liquid discharge channels reduces local resistance, making the airflow and liquid flow smoother and reducing pressure loss. The evenly distributed inlet and outlet design helps reduce pressure fluctuations within the device, improving the stability and reliability of equipment operation. It adapts to the needs of large-flow operations, enabling the preparation and spraying of large quantities of liquid medicine in a short time, improving work efficiency.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
