Description

Technical Field

[0001] The invention relates to the technical field of agricultural pest control, and in particular to an automatic medicine dispensing and spraying device with multiple medicine boxes. Background Art

[0002] In the field of agricultural production, in order to achieve precise maintenance of crops and control of pests and diseases, the application of automatic crop spraying devices is becoming more and more widespread. An existing automatic crop spraying device uses advanced image recognition technology to determine the cause of crop disease, and then selects and sprays the corresponding medicines, which improves the efficiency and scientificity of agricultural production to a certain extent. However, there are some significant technical problems in the actual application of this device. First, in order to meet the needs of dispensing medicines for different causes of disease, a variety of independent containers containing premixed medicines are set inside the device. However, this results in a more complex overall structure of the equipment and occupies a larger space, which not only increases the manufacturing cost of the device, but also limits its application in small farmlands or complex terrains to a certain extent.

[0003] Secondly, although the setting of multiple mixing chambers is intended to achieve precise drug dispensing, in actual operation, due to factors such as the structure of the mixing chamber and the stirring method, the drug mixing is often not sufficient. This may lead to uneven drug concentration, affect the spraying effect, fail to effectively treat the cause of the crop, and may even cause damage to the crop due to excessive local drug concentration. In addition, after the device completes the spraying operation, there will often be residual liquid in the mixing chamber. These residual liquids not only cause a waste of drugs, but may also affect the subsequent accuracy of drug dispensing and the spraying effect due to the deterioration or cross-contamination of the residual liquid. In summary, the existing crop automatic spraying device based on image recognition of crop causes for selective spraying has certain advantages in intelligence and precision, but due to the limitations of its internal structure and working method, there are still technical problems that need to be solved in terms of space occupation, mixing effect and residual liquid treatment.

[0023] Reference Figure 1~Figure 4In an embodiment of the present invention, an automatic dispensing spray device for multiple medicine boxes is proposed, comprising an outer shell 1, the bottom of the outer shell 1 has a total liquid flow outlet 101, and the total liquid flow outlet 101 is connected to the outside; an inner shell 2 is arranged inside the outer shell 1, the inner shell 2 has a first inner cavity 201, and a second inner cavity 202 is formed between the outer shell 1 and the inner shell 2, the first inner cavity 201 has a first air flow inlet 203 and a first liquid flow outlet 204, and the first air flow inlet 203 is connected to the outside; there are a plurality of liquid medicine bottles 3, and the plurality of liquid medicine bottles 3 are arranged on the outer shell 1. On the outer wall, the medicine liquid bottle 3 has a medicine liquid cavity 301, and the medicine liquid cavity 301 leads to the first inner cavity 201; the bottom support member 4 is arranged in the first inner cavity 201; the first sliding member 5 is arranged in the first inner cavity 201 for lifting and sliding, and a first stirring space 501 is formed between the first sliding member 5 and the bottom support member 4, the first air flow inlet 203 and the first liquid flow outlet 204 are both connected to the first stirring space 501, and the first liquid flow outlet 204 leads to the total liquid flow outlet 101, and the first sliding member 5 is configured to compress or cancel the compression of the first stirring space 501 after lifting and sliding.

[0024] In this embodiment, the outer shell 1 is a hollow cylindrical structure, and a total liquid outflow outlet 101 is provided at the bottom thereof. The inner shell 2 is also cylindrical and is installed inside the outer shell 1, and a ring-shaped second inner cavity 202 is formed between the two. A plurality of medicine bottles 3 are evenly arranged on the outer wall of the outer shell 1 in a circumferential manner, and each medicine bottle 3 has a medicine liquid 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 with the inner wall of the first inner cavity 201. First, different medicine liquids are respectively injected into the medicine liquid cavity 301 of each medicine bottle 3. When it is necessary to dispense medicine, the external airflow enters the first inner cavity 201 through the first airflow inlet 203. The first sliding member 5 is lifted and slid under the action of the driving device. When the first sliding member 5 descends, it compresses the first inner cavity 201, and at this time, the medicine liquid and the airflow are fully mixed under the action of pressure. Subsequently, the first sliding member 5 continues to descend, completely squeezing out the mixed liquid medicine, which flows to the total liquid outlet 101 through the first liquid outlet 204, thus completing a complete dispensing and spraying action. By introducing air and using the sliding member to squeeze the cavity, it is possible to fully mix and drain the liquid medicine in a single cavity, avoiding the structural complexity and space occupation problems caused by setting up multiple cavities, making the device more concise and compact. This unique mixing and draining method ensures the accuracy and consistency of each dispensing, reduces liquid medicine residue and waste, and improves the utilization rate of the liquid medicine. The simple structural design reduces the equipment cost and manufacturing difficulty, while also reducing the possibility of failures, making it easy to maintain and service. The amount of air entering and the motion parameters of the sliding member can be flexibly adjusted according to different liquid medicine formulas and spraying requirements, and has strong adaptability.

[0025] Furthermore, it also includes a drug delivery tube 6, one end of which is connected to the drug liquid chamber 301, and the other end is arranged on the first sliding member 5, and passes through the first sliding member 5 to be connected to the first stirring space 501; an electric control valve 7 is arranged on the drug delivery tube 6, there are several electric control valves 7, and each drug delivery tube 6 is provided with an electric control valve 7.

[0026] In this embodiment, the drug delivery tube 6 is a slender pipe, one end of which is connected to the drug liquid chamber 301 of the drug liquid bottle 3, and the other end passes through the first sliding member 5 and is connected to the first stirring space 501. An electric control valve 7 is installed on each drug delivery tube 6. After the image recognition system determines the type of crop disease, the control system determines the type of drug liquid to be extracted according to the preset formula. When a certain drug liquid needs to be extracted, the corresponding electric control valve 7 is opened. At this time, as the first sliding member 5 moves upward, negative pressure is generated in the first stirring space 501, and the drug liquid is drawn from the drug liquid chamber 301 into the first stirring space 501 through the drug delivery tube 6. When a certain type of drug liquid does not need to be extracted, the corresponding electric control valve 7 remains closed, and the drug liquid will not be extracted. The drug extraction method in which the first sliding member moves upward to generate negative pressure has a simple structure and stable operation, and can accurately extract the required amount of drug liquid. The precise control of the electric control valve avoids the mixing of unnecessary drug liquid and ensures the accuracy and purity of the drug liquid formula. It can quickly respond to changes in crop diseases and adjust the dispensing plan in time, improving operation efficiency and flexibility. It reduces errors in manual judgment and operation, and improves the reliability and consistency of dispensing. It effectively utilizes equipment space, realizes an intelligent and automated dispensing process, and reduces labor intensity and costs.

[0027] Furthermore, the bottom support member 4 has a concave arc bottom groove 401 , the edge of the bottom support member 4 is the lowest point of the concave arc bottom groove 401 , and the first liquid outlet 204 is located at one side of the concave arc bottom groove 401 .

[0028] In this embodiment, the bottom support member 4 is disc-shaped, with the highest middle part and the concave edge forming a concave arc bottom groove 401. The first liquid flow outlet 204 is located on one side of the concave arc bottom groove 401. During the dispensing and stirring process, the mixed liquid medicine naturally flows to the concave arc bottom groove 401 at the edge of the bottom support member 4 due to gravity. When the first sliding member 5 is squeezed, the liquid medicine can flow quickly and concentratedly along the concave arc bottom groove 401 to the first liquid flow outlet 204, so as to be discharged smoothly for spraying. The design of the concave edge of the middle part of the bottom support member 4 can more effectively guide the liquid medicine to converge to the edge, so that the liquid medicine can flow to the first liquid flow outlet 204 more quickly and concentratedly, significantly improving the discharge efficiency. The concave arc bottom groove 401 with a concave edge can minimize the residual liquid medicine on the bottom support member 4, ensure that the liquid medicine is fully discharged, and maximize the utilization rate of the liquid medicine. It helps to ensure that the discharge amount of the liquid medicine after each dispensing is stable and consistent, further improving the accuracy and effect of dispensing and spraying. The accumulation of liquid medicine inside the device is reduced, the possibility of liquid medicine deterioration and cross contamination is reduced, and the quality and efficacy of the liquid medicine are guaranteed.

[0029] Furthermore, it also includes a first blade 8, which is rotatably arranged in 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 respectively cooperate with the top of the concave arc bottom groove 401 and the shape of the bottom of the first sliding member 5. The first blade 8 is configured so that after the first sliding member 5 slides downward, the upper and lower ends of the first blade 8 respectively slide against the first sliding member 5 and the concave arc bottom groove 401.

[0030] In this embodiment, a first blade 8 is newly added to the automatic dispensing spraying device of the multi-medicine box. When the first sliding member 5 descends, the first blade 8 is pushed to rotate, and at the same time, the upper and lower ends of the first blade 8 are tightly slidably abutted with 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 medicine liquid and the airflow. The rotation of the first blade 8 can further enhance the mixing effect of the medicine liquid and the airflow, making the medicine liquid mixed more evenly and fully. The tight sliding abutment with the first sliding member 5 and the concave arc bottom groove 401 reduces the leakage and residue of the medicine liquid during the stirring process, and improves the utilization rate of the medicine liquid. It can promote the flow of the medicine liquid in the first stirring space 501 to avoid the occurrence of local uneven mixing. And the inner wall can be scraped in real time.

[0031] Furthermore, the first air flow inlet 203 is located above the first liquid flow outlet 204, and also includes a second sliding member 9, which is slidably arranged in the second inner cavity 202, and the second sliding member 9 rises and slides synchronously with the first sliding member 5. The second sliding member 9 is configured to block or unblock the first air flow inlet 203 or the first liquid flow outlet 204 after rising and sliding.

[0032] In this embodiment, during operation, the first sliding member 5 and the second sliding member 9 first rise synchronously. Since the first airflow inlet 203 is located above the first liquid outlet 204, gas is first sucked from the first airflow inlet 203 at the initial stage of rising, so that a certain amount of gas is stored in the first stirring space 501. Subsequently, the second sliding member 9 slides to block the first airflow inlet 203. A rib is provided on the side of the second sliding member 9 close to the inner shell 2, and the rib is close to the inner shell 2. At this time, a closed state is formed in the first stirring space 501. As the first sliding member 5 rises, the rib of the second sliding member 9 continues to slide on the outer wall of the inner shell 2, maintaining the closed state of the size of the first stirring space 501. The first sliding member 5 and the second sliding member 9 continue to slide upward, and the negative pressure continues to decrease. The drug liquid is sucked into the first stirring space 501 from the drug liquid cavity 301 through the drug 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 space height of the first stirring space 501. Then, the first sliding member 5 and the second sliding member 9 slide down for pressurization. As the pressure is pressed down, the first sliding member 5 pumps the mixed liquid medicine out to the next cavity. Continue to press down to discharge all the residual liquid medicine and excess liquid in the first stirring space 501, and then the second sliding member 9 blocks and pressurizes the lower section of the second inner cavity 202. This action sequence of first sucking air to form a negative pressure, then sucking liquid, and then pressurizing and discharging liquid can accurately control the suction and discharge amount of the liquid medicine, and ensure the accuracy and stability of the medicine dispensing. The spatial position relationship is effectively utilized, and the continuous process of gas suction, liquid medicine suction, mixed pressurization and liquid discharge is realized through reasonable sliding member action, which improves work efficiency. The method of forming negative pressure liquid suction can ensure the full suction of the liquid medicine, avoid liquid medicine residue and waste, and improve the utilization rate of the liquid medicine. Multiple pressurization and liquid discharge can discharge the liquid medicine in the first stirring space 501 to the greatest extent, reduce the accumulation of liquid medicine, and reduce the risk of liquid medicine deterioration and cross contamination.

[0033] Furthermore, the second inner cavity 202 is an annular cavity, and has a truncated cone section 205 at the bottom, and the diameter of the truncated cone section 205 gradually decreases towards the total liquid flow outlet 101 .

[0034] In this embodiment, in the process of the medicinal liquid flowing from the first inner cavity 201 to the total liquid outflow outlet 101, when passing through the truncated cone section 205 of the second inner cavity 202, the flow rate of the medicinal liquid will gradually increase due to the gradual decrease in diameter, so that it will flow to the total liquid outflow outlet 101 more smoothly. The design of the truncated cone section 205 can play a role in guiding flow, speed up the flow rate of the medicinal liquid, improve the drainage efficiency, and reduce the residence time of the medicinal liquid in the device. It helps to ensure the continuous and stable discharge of the medicinal liquid, avoid blockage or poor flow, and improve the reliability of the device. The gradually decreasing diameter can produce a certain pressure difference, promote the discharge of the medicinal liquid, reduce dependence on external power, and save energy.

[0035] Furthermore, it also includes a second blade 10 , which is rotatably disposed in the truncated cone section 205 , and the second blade 10 maintains sliding contact with the inner wall of the truncated cone section 205 and the bottom wall of the inner shell 2 .

[0036] In this embodiment, when the medicine liquid flows through the truncated cone section 205, it drives the second blade 10 to rotate. The rotation of the second blade 10 further promotes the flow of the medicine liquid, allowing it to flow more smoothly to the total liquid outflow port 101. The rotation of the second blade 10 can enhance the flow dynamics of the medicine liquid, speed up the discharge speed of the medicine liquid, and improve work efficiency. The sliding abutment with the inner wall of the truncated cone section 205 and the bottom wall of the inner shell 2 reduces the leakage and residue of the medicine liquid during the flow process and improves the utilization rate of the medicine liquid. It further promotes the mixing and uniform distribution of the medicine liquid and ensures the consistency of the composition of the medicine liquid. It increases the stability of the flow of the medicine liquid, reduces the generation of turbulence and vortices, and is conducive to accurately controlling the discharge amount of the medicine liquid.

[0037] 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 arranged on the main shaft 11, and the main shaft 11 is threadedly connected to the first sliding member 5.

[0038] In this embodiment, when the first sliding member 5 is lifted and slid, the threaded connection with the main shaft 11 drives 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, thereby playing a role in the mixing and flow of the liquid medicine. The sliding of the first sliding member 5 drives the main shaft 11 to rotate, thereby realizing the linkage of the movements of the components, reducing the additional driving device, and simplifying the equipment structure and control process. The rotation of the main shaft 11 drives the blades to rotate, thereby enhancing the stirring and flow effects of the liquid medicine, making the liquid medicine mix more evenly and flowing more smoothly. The threaded connection method makes the transmission between the first sliding member 5 and the main shaft 11 stable and reliable, and can accurately control the rotation speed and angle of the blades.

[0039] Furthermore, the first blades 8 and the second blades 10 are arranged in a plurality of circles and are inclined.

[0040] In this embodiment, during the operation of the equipment, with the rotation of the main shaft 11 and the flow of the medicine, multiple inclined first blades 8 and second blades 10 act simultaneously to stir and push the medicine. Several circularly arranged blades can act on the medicine in a larger range, improving the efficiency and uniformity of stirring and flow. The inclined blades can generate axial and radial driving forces when rotating, enhancing the mixing effect and flow speed of the medicine. The design of evenly arranged and inclined blades makes the force on the medicine in the device more balanced, reducing local eddy currents and stagnation. The contact area and action time between the blades and the medicine are increased, further improving the mixing quality of the medicine and the stability of discharge.

[0041] Furthermore, the first air flow inlet 203 and the first liquid flow outlet 204 are arranged on the inner shell 2 in a plurality of circles.

[0042] In this embodiment, when the device is working, multiple first air flow inlets 203 take in air at the same time, so that the gas can enter the first stirring space 501 more evenly and mix fully with the liquid medicine. Multiple first liquid flow outlets 204 discharge liquid at the same time to ensure the smoothness and uniformity of liquid medicine discharge. The multiple air flow inlets and liquid flow outlets arranged in a circle can make the gas and liquid medicine more evenly distributed in the first stirring space, improve the mixing effect and discharge efficiency. The number of channels for air intake and liquid discharge is increased, the local resistance is reduced, the flow of air and liquid flow is smoother, and the pressure loss is reduced. The evenly distributed inlet and outlet design helps to reduce the pressure fluctuations inside the device and improve the stability and reliability of the equipment operation. It can adapt to the operation requirements of larger flow rates, and can complete the preparation and spraying of a large amount of liquid medicine in a short time, thereby improving work efficiency.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
