Description

Technical Field

[0001] This invention relates to the field of papaya cultivation technology, and in particular to a portable quantitative automatic infusion device for papaya and its usage method. Background Technology

[0002] Papaya is rich in vitamin C, vitamin A, and fiber, which are beneficial to the digestive and immune systems. It also contains an enzyme called papain, which helps promote digestion and improve skin health. However, nutrient deficiencies in papaya can lead to deformed, tumor-like fruits that are unsuitable for consumption or sale, severely limiting the healthy development of the papaya industry. Furthermore, traditional soil and foliar application of chemical fertilizers has low utilization rates, resulting in significant resource waste and environmental pollution, which is detrimental to environmental protection and ecological health. Injecting a small amount of compound fertilizer solution into the pith cavity of the papaya trunk can effectively solve these problems. However, quantitative infusion into the papaya pith cavity requires multiple people and is difficult to perform manually, resulting in low accuracy, high labor costs, and is time-consuming and labor-intensive. Additionally, it is impossible to adjust or extract the appropriate amount of fertilizer based on the specific needs of the papaya pith cavity, leading to poor treatment of nutrient deficiencies and difficulty in ensuring a low recurrence rate. Therefore, there is an urgent need to invent a device that can automatically dispense water in a quantitative manner with one click and deliver it quickly to solve the above problems, so as to ensure that all plants are fertilized evenly, and that it is convenient and quick to operate by a single person, saving time and labor.

[0042] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0043] like Figure 1 As shown, the first aspect of the present invention provides a portable quantitative automatic infusion device for papaya, including a drug supply mechanism, a quantitative control mechanism, and a blockage unblocking mechanism.

[0044] like Figure 1 , 6 As shown, the quantitative control mechanism includes an automatic infusion set 101. A handle 102 is mounted on the side of the automatic infusion set 101, and a USB charging port 103 is provided on the side of the handle 102. A control panel 104 is provided above the automatic infusion set 101. The control panel 104 is provided with a quantitative selection key 105 and a dispensing key 106. A display screen 603 is provided between the quantitative selection key 105 and the dispensing key 106. The control panel 104 is located directly above the handle 102. The automatic infusion set 101 is connected to a drug supply mechanism.

[0045] like Figure 1 , 5 As shown in Figure 6, a stainless steel infusion tube 107 is fixedly installed on the top of the automatic infusion set 101. The bottom end of the stainless steel infusion tube 107 is embedded in one end of a first connecting hose 108. The other end of the first connecting hose 108 is connected to one side of the outlet of the pump 109. One end of a second connecting hose 201 is installed at the other side of the pump 109.

[0046] like Figure 6 As shown, the other end of the second connecting hose 201 is connected to the liquid supply mechanism, a photocurrent velocity sensor is provided between the liquid pump 109 and the first connecting hose 108, and a control circuit board is installed inside the control panel 104.

[0047] It should be noted that when administering compound fertilizer solution or pesticide infusion to the pith cavity of a papaya tree, hold the handle 102 and insert the stainless steel infusion tube 107 into the drilled hole on the papaya trunk. Control the dispensing volume using the quantitative selection key 105 on the control panel 104. Selectable dispensing volumes include 0.3 liters, 0.6 liters, 1 liter, 1.5 liters, and 1.8 liters, which can be selected according to the actual conditions of papaya cultivation, facilitating the planting needs of different papaya pith cavities and improving planting quality. After selecting the dispensing volume, press the dispensing key 106; at this point, the control... The circuit board transmits a control signal to start the liquid pump 109 to extract the medicine. The medicine is delivered through the first connecting hose 108 and the second connecting hose 201, and finally output to the papaya pith cavity through the stainless steel infusion tube 107, achieving the effect of quantitative infusion. The infusion volume is precisely controlled, and the manual adjustment of the extraction volume is saved. The infusion rate is increased. At the same time, it replaces the traditional syringe injection method, which is simple and efficient to operate, further improving the efficiency and quality of papaya cultivation. The USB charging port 103 can charge the power supply battery, improving the device's infusion endurance.

[0048] like Figure 2 , 4 As shown, the liquid medicine supply mechanism includes two sets of dispensing modules. Each set of dispensing modules includes a housing 202. The inner wall of the housing 202 is provided with two symmetrical second slides 203. A second slide groove 204 is installed on each second slide groove 203. A rack 205 is fixedly welded to the top of the second slide groove 204. The teeth on the rack 205 mesh with a gear 206. The gear 206 is installed on the output shaft of a first micro servo motor 207. The bottom of the first micro servo motor 207 is fixedly installed on the inner wall of the housing 202. Two medicine inlet holes 208 are opened on the top of the housing 202. A rectangular liquid storage cavity 209 is provided below each medicine inlet hole 208. A magnet 301 is welded and fixed to the side of the rack 205, and the side of the magnet 301 is in contact with and attached to one side of the rectangular liquid storage cavity 209.

[0049] like Figure 2 , 7 As shown, a waterproof sealing shell 302 is provided inside the rectangular liquid storage cavity 209. A drug injection through hole 303 is opened in the middle of the waterproof sealing shell 302. A nickel metal ring 304 is installed on the outside of the drug injection through hole 303, and the nickel metal ring 304 is placed inside the waterproof sealing shell 302. An electric wire 305 is wound around the outside of the nickel metal ring 304. The input and output ends of the electric wire 305 are connected to a power source. The top of the rectangular liquid storage cavity 209 is connected to a sealing cover 306 through a hinge. A rack through hole 307 is opened on the side of the sealing cover 306. A rack protective cover 308 is welded above the rack through hole 307.

[0050] like Figure 1 ,3 As shown, the bottom of each rectangular liquid storage chamber 209 is connected to one end of a third connecting hose 309, and the other end of the third connecting hose 309 is fixed to the liquid inlet cover 401. The liquid inlet cover 401 is installed above the liquid inlet 402, which is located on the top of the backpack liquid storage tank 403. The chassis 202 is fixed to the front of the backpack liquid storage tank 403. The top of the backpack liquid storage tank 403 is also provided with a liquid outlet 404, and a liquid outlet cover 405 is installed above the liquid outlet 404. The liquid outlet cover 405 is connected to the second connecting hose 201. The backpack liquid storage tank 403 is provided with two shoulder straps 406, and a handle 602 is located on the top of the backpack liquid storage tank 403.

[0051] It should be noted that before administering intravenous fluid to the pith cavity of papaya, a suitable compound fertilizer, chemical fertilizer, or pesticide solution needs to be selected or prepared. First, open the sealing cap 306 and add the solution to be prepared or used into the rectangular storage cavity 209. The solution flows into the waterproof sealing shell 302 below through the injection hole 303. This controls the start of the first micro servo motor 207. The output shaft of the first micro servo motor 207 drives the gear 206 to rotate forward. The gear 206 drives the racks 205 on both sides to move up and down, thereby causing the magnet 301 to move downward on one side of the rectangular storage cavity 209. At this time, the starting power supply provides current to the wire 305 in the corresponding rectangular storage cavity 209, causing the nickel metal ring 304 to generate an electromagnetic field. The force causes the magnet 301 to move downwards, which in turn moves the nickel metal ring 304 and the waterproof sealing shell 302 in the rectangular liquid storage cavity 209 corresponding to the solution to be prepared or used downwards. This presses the solution in the rectangular liquid storage cavity 209, and the pressed solution flows into the backpack liquid storage tank 403 through the third connecting hose 309 for infusion preparation. At this time, the staff carries the backpack liquid storage tank 403 on their back with two shoulder straps. The solution in the backpack liquid storage tank 403 is extracted and injected through the quantitative control mechanism, so that the medicine can be prepared or used according to the appropriate ratio. This achieves precise solution preparation and extraction, effectively improves the quality of papaya planting, and is convenient for extraction at any time, with high portability.

[0052] like Figure 5 As shown, the blockage clearing mechanism includes two sets of extrusion modules. Each set of extrusion modules has the same configuration. Each extrusion module includes two opposing first slides 407. The first slides 407 are fixed in a cross shape. Each first slide 407 is connected to a first groove 408. A rectangular plate 409 is fixed above the first groove 408. An extrusion assembly is installed above the rectangular plate 409. A drive mechanism is connected to both sides of the first groove 408.

[0053] like Figure 5As shown, the extrusion assembly includes an extrusion block 501, the extrusion block 501 has an arc-shaped groove 502, the arc-shaped groove 502 has an arc-shaped protrusion 503 inside, and a connecting post 504 is provided below the extrusion block 501, the connecting post 504 is fixed directly above the rectangular plate 409.

[0054] like Figure 5 As shown, the drive mechanism includes two screw mounting plates 505. The screw mounting plate 505 is fixed to the end of the first slide rail 407. Two double-threaded screws 506 are connected and installed between the two screw mounting plates 505. The two double-threaded screws 506 are symmetrically installed on the same thread side, and each double-threaded screw 506 protrudes from one of the screw mounting plates 505. Each protruding part is used to install a first drive gear 507. A second drive gear 508 meshes between the two first drive gears 507. The second drive gear 508 is fixedly installed on the output rod of the second micro servo motor 509. Transmission nuts 601 are connected and installed at different threads on the two double-threaded screws 506. The transmission nuts 601 corresponding to the same thread on each double-threaded screw 506 are symmetrical and parallel. The rectangular plate 409 is fixed between the two symmetrical and parallel transmission nuts 601.

[0055] It should be noted that certain compound fertilizers, chemical fertilizers, and pesticides contain fine pesticide particles. These particles can cause blockages in the connecting hoses during delivery, slowing down the pesticide output rate or even causing backflow and damaging the pump 109. Therefore, it is necessary to squeeze and clear the blockage of pesticide particles. The second micro servo motor 509 is then activated to drive the second drive gear 508 to rotate. This second drive gear 508 drives the first drive gear 507, which in turn drives the two double-threaded screws 506 to rotate. At this time, different threads on each double-threaded screw 506... The two transmission nuts 601 on the rod move relative to each other. The transmission nuts 601 drive the first slide groove 408 to slide on the first slide rail 407, thereby driving the rectangular plate 409 to slide relative to each other. This causes the rectangular plate 409 to drive the arc-shaped protrusions 503 on the two relatively moving extrusion blocks 501 to extrude the blocked connecting hose. Each set of extrusion components extrudes alternately, which can make the drug particles spread quickly, thereby achieving the effect of quickly clearing the blockage, improving the efficiency of drug delivery, avoiding damage to the automatic infusion set due to frequent blockage, extending the service life of the device, effectively making the infusion smoother and improving the quality of infusion.

[0056] Another aspect of the present invention provides a method of using a portable automatic quantitative infusion device specifically for papaya, applicable to any of the portable automatic quantitative infusion devices specifically for papaya described in any one of the claims, comprising the following steps:

[0057] S1: Powering on the starter causes the nickel metal ring to generate electromagnetic force. According to the drug preparation plan, the third micro servo motor is activated to drive the nickel metal ring to move downwards and squeeze the drug to obtain the prepared drug, which is then stored in a backpack-type storage tank.

[0058] S2: Preset infusion volume, the control circuit board starts the pump to extract the squeezed medicine based on the infusion volume;

[0059] S3: Set the pumping speed of the pump according to the infusion volume to obtain the pumping speed. Based on the pumping speed, inject the squeezed medicine into the papaya pith cavity through the stainless steel infusion tube until the infusion is completed and then turn off the automatic infusion device.

[0060] S4: The flow rate of the liquid medicine in the first connecting hose is detected by the photocurrent velocity sensor to obtain the liquid medicine flow rate value. It is determined whether the liquid medicine flow rate value is less than the preset flow rate value. If it is less than the preset flow rate value, the first connecting hose is blocked. The deviation value between the liquid medicine flow rate value and the preset flow rate value is calculated to obtain the flow rate deviation value.

[0061] S5: Based on the flow rate deviation value, start the second micro servo motor to drive the extrusion module to extrude and clear the liquid particles blocked in the first connecting hose.

[0062] It should be noted that when the wire 305 is energized, the nickel metal ring 304 generates an electromagnetic force, which the magnet 301 uses to attract the nickel metal ring 304 downwards to compress the solution for mixing. If the current is removed from the wire 305, the electromagnetic force disappears, and the magnet 301 can no longer attract the nickel metal ring 304 to continue moving downwards. Therefore, the solution can be quantitatively mixed by controlling the flow of current. The infusion volume varies for each papaya, so it needs to be set according to the actual situation. The pumping speed of the pump 109 can be intelligently adjusted according to the set infusion volume to achieve a rapid and uniform infusion effect. The photocurrent velocity sensor will detect the flow rate in real time. The flow rate of the solution in the first connecting hose 108 is monitored. When drug particles block the first connecting hose 108, the photocurrent velocity sensor acquires the current flow rate of the solution and determines whether the flow rate is less than a preset value. If it is less, it indicates that the first connecting hose 108 is blocked. The deviation between the flow rate and the preset value is calculated, and an abnormal electrical signal is sent to the control system based on the deviation value. This activates the blockage clearing mechanism to squeeze and clear the blocked drug particles in the first connecting hose 108, thereby quickly clearing the blockage and preventing frequent blockages that could damage the device, thus improving the device's lifespan.

[0063] Furthermore, in a preferred embodiment of the present invention, the step of activating the third micro servo motor to drive the nickel metal ring downward to extrude the medicine according to the medicine preparation scheme specifically includes the following steps:

[0064] S102: Obtain historical growth information of papaya malformed tumor fruits, import the historical growth information of papaya malformed tumor fruits into a big data network for identification and matching, obtain the corresponding pesticide type, and obtain the standard dosage of the pesticide type.

[0065] S104: Construct a drug formulation and preparation system based on the corresponding drug type and the standard dosage, and determine the original preparation ratio of the drug according to the drug formulation and preparation system;

[0066] S106: Preset the required amount of pesticide for the current papaya planting, calculate the ratio adjustment factor by the required amount of pesticide and the original mixing ratio of the pesticide, generate the mixing ratio relationship, define the standard dosage of the pesticide type as a specific benchmark value, calculate the relationship between the mixing ratio relationship and the specific benchmark value, and obtain the ratio adjustment factor of the amount of pesticide.

[0067] S108: Calculate the mixing ratio by using the ratio adjustment factor of the dosage and the original mixing ratio of the drug to obtain the mixing ratio after the required dosage change;

[0068] S110: Determine whether the mixing ratio after the change in the required dosage meets the preset ratio range. If it does, use the mixing ratio after the change in the required dosage as the drug preparation plan and upload it to the control terminal.

[0069] It should be noted that the historical growth information of the deformed, tumor-bearing papaya fruits includes information such as the historical individual growth shape, historical number, and historical distribution of the deformed, tumor-bearing fruits. Nutrient deficiency in papaya can cause mutations in the planted papayas, resulting in deformed, tumor-bearing fruits. Since the planting conditions of each papaya are different, different compound fertilizer solutions, chemical fertilizers, and pesticides can be selected or adjusted based on the historical growth information of the papaya. Different dosages of pesticides will correspond to different mixing ratios, so it is necessary to calculate the corresponding mixing ratios after the dosage changes. First, determine the mixing ratio based on the historical growth information. This method involves determining the type of pesticide to be applied and obtaining the standard dosage for that pesticide type. Based on these two factors, the original mixing ratio of the pesticide is determined. The required dosage for papaya cultivation is preset, and then a ratio adjustment factor is calculated based on the original mixing ratio and the required dosage. Finally, the final mixing ratio based on the adjusted dosage is calculated using the original mixing ratio and the ratio adjustment factor. It is then determined whether the adjusted mixing ratio conforms to the preset ratio range. If it does, the adjusted mixing ratio is output as the pesticide solution preparation plan. This method can calculate the pesticide solution preparation ratio based on the required dosage, enabling more precise treatment of papaya nutrient deficiency, improving the targeted treatment of nutrient deficiency, effectively ensuring the quality of papaya pith infusion, and avoiding the recurrence rate of nutrient deficiency.
