Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and in particular to an intelligent mixing device for agricultural fertilizers and pesticides for controlling corn leaf spot. Background Art

[0002] Corn leaf spot is a common fungal disease in corn production, caused by Helicoverpa maydis. It is prone to outbreaks under high temperature and humidity. The disease primarily affects leaves, initially producing small, brown, water-soaked spots that expand into oval or nearly circular lesions with brown edges and yellow-brown centers. When humid, a gray-black mold layer forms on the surface of the lesions. In severe cases, the lesions become continuous, causing leaf dieback and impacting photosynthesis, which can reduce yield by 10%-30% or even more. The disease can also infect leaf sheaths, bracts, and ears, reducing grain quality. Prevention and control measures require comprehensive measures, including the selection of disease-resistant varieties, appropriate crop rotation, removal of diseased debris to reduce the source of fungi, spraying fungicides such as carbendazim and tebuconazole at the early stages of the disease, and strengthening field management to enhance plant resistance.

[0003] Chinese patent CN216451901U discloses a pesticide mixing irrigation box for agricultural fertilization and irrigation, comprising a mixing irrigation device, the top of which is fixedly connected to a motor; the pesticide mixing irrigation box for agricultural fertilization and irrigation can improve the mixing irrigation device's ability to fully stir fertilizer and water, avoid the problem of insufficient mixing of fertilizer and water during the mixing process, improve the working efficiency of the mixing irrigation device, and reduce the workload of staff. It solves the problem that a general pesticide mixing irrigation box has a simple structure and cannot fully stir the fertilizer and water inside the pesticide mixing irrigation box, resulting in the need for secondary stirring between the fertilizer and water, which increases the workload of staff and reduces the working efficiency of the pesticide mixing irrigation box, thereby improving the efficiency of the pesticide mixing irrigation box for agricultural fertilization and irrigation.

[0004] In the comprehensive prevention and control system of corn leaf spot, the precise preparation of agricultural fertilizer and pesticide compound formulations is a key link in achieving the synergistic effect of "nutritional disease resistance-chemical antibacterial". This technology requires that functional substances such as fungicides (such as triazoles, methoxyacrylates), trace element fertilizers (zinc, manganese, potassium, etc.) and biostimulants be dissolved in irrigation water or spray carriers according to scientific proportions, and precise operations are implemented through integrated water and fertilizer or foliar spraying technology.

[0031] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] See also Figures 1 to 9In an embodiment of the present invention, an intelligent mixing device for agricultural fertilizers and pesticides for controlling corn leaf spot disease includes a mixing tank 1, a plurality of medicine storage tanks 2 arranged on the outside of the mixing tank 1, a plurality of infusion mechanisms 3 arranged at the top of the mixing tank 1, and a stirring mechanism arranged inside the mixing tank 1. The top of the mixing tank 1 is connected to a water inlet 101, and an electronic flow meter 102 is provided on the water inlet 101. The bottom of the mixing tank 1 is connected to a liquid outlet 103, and an electromagnetic valve 104 is provided on the liquid outlet 103. The liquid outlet 103 is connected to the fertilizer or pesticide spraying equipment on the agricultural equipment to directly output for use. The number of infusion mechanisms 3 is the same as the number of medicine storage tanks 2. The infusion mechanism 3 is used to input the liquid fertilizer or pesticide in the medicine storage tank 2 into the mixing tank 1. The infusion mechanism 3 includes a cylinder 301, a piston 302 slidably installed in the cylinder 301, and a screw fixedly installed on the top of the piston 302. The rod 303 and the first gear 304 threadedly mounted on the screw 303, a driving disk 6 for pushing the first gear 304 downward is provided above the mixing tank 1, when the driving disk 6 pushes the first gear 304 downward, the first gear 304 drives the piston 302 downward through the screw 303 to input the liquid fertilizer or medicine in the cylinder 301 into the mixing tank 1, the screw 303 can only move up and down relative to the cylinder 301 and cannot rotate on its own, and a limiting structure can be provided on the cylinder 301 to limit the screw 303; the height of the first gear 304 on the screw 303 determines the stroke of the piston 302, the higher the height, the more raw materials are output from the cylinder 301 each time the piston 302 is pressed down, and thus the higher the proportion in the compound preparation, the system converts the ratio parameter into a specific position value of the first gear 304 through a preset mathematical model, such as a stroke-volume conversion formula;

[0033] A spring 306 is fixedly connected to the top of the cylinder 301, and a connecting ring 305 is rotatably mounted on the bottom of the first gear 304. The top of the spring 306 is fixedly connected to the connecting ring 305. The arrangement of the spring 306 enables the first gear 304 to drive the first screw 303 and the piston 302 to move upward under the elastic action of the spring 306 when the driving plate 6 moves upward, until the piston 302 contacts the top inner wall of the cylinder 301, thereby resetting the piston 302.

[0034] The bottom of the cylinder 301 is connected to a liquid inlet pipe 307 and a liquid outlet pipe 308. The bottom end of the liquid inlet pipe 307 extends into the bottom of the inner cavity of the medicine storage tank 2, and a filter 311 is fixedly installed at the bottom end of the liquid inlet pipe 307. The bottom end of the liquid outlet pipe 308 extends into the interior of the mixing tank 1. A first one-way valve 309 is provided on the liquid inlet pipe 307, and a second one-way valve 310 is provided on the liquid outlet pipe 308. The first one-way valve 309 allows the liquid fertilizer or medicine in the medicine storage tank 2 to be input into the cylinder 301 through the liquid inlet pipe 307, while the liquid fertilizer or medicine in the cylinder 301 cannot be input into the medicine storage tank 2 through the liquid inlet pipe 307. The second one-way valve 310 allows the liquid fertilizer or medicine in the cylinder 301 to be input into the mixing tank 1 through the liquid outlet pipe 308, while the liquid fertilizer or medicine in the mixing tank 1 cannot enter the cylinder 301 through the liquid outlet pipe 308.

[0035] During specific use, the medicine for treating corn leaf spot and liquid fertilizer are put into the medicine storage tank 2 through the feeding port 201 above the medicine storage tank 2. Before preparing the compound preparation of agricultural fertilizer and pesticide, the position of each first gear 304 on the screw 303 is adjusted first. The higher the height of the first gear 304 on the screw 303, the higher the proportion of the medicine or liquid fertilizer corresponding to the cylinder 301 in the compound preparation of agricultural fertilizer and pesticide. Therefore, the ratio of each liquid fertilizer and medicine is adjusted according to the formula, and then the piston 302 is driven to move downward and then upward once, so that the liquid fertilizer or medicine in the medicine storage tank 2 is filled into the cylinder 301. When preparing the compound preparation of agricultural fertilizer and pesticide, water is input through the water inlet 101, and the flow rate of the input water is calculated by the electronic flow meter 102, and the drive disk 6 is controlled to move downward at the same time. After the driving disc 6 contacts the first gear 304, the driving disc 6 pushes the first gear 304 to move downward, thereby pushing the piston 302 downward through the screw 303, so that the liquid fertilizer or medicine in the cylinder 301 is input into the mixing tank 1 through the liquid outlet pipe 308. The input speed of the liquid fertilizer and the water is adapted to the input speed so as to be mixed according to the ratio. After the piston 302 moves downward until it contacts the bottom inner wall of the cylinder 301, the driving disc 6 is controlled to move upward, so that the first gear 304 moves upward under the elastic action of the spring 306, thereby driving the piston 302 to move upward through the screw 303, and then the liquid fertilizer or medicine in the medicine storage tank 2 is input into the cylinder 301 through the liquid inlet pipe 307 to replenish the liquid fertilizer or medicine in the cylinder 301.

[0036] The present invention realizes the precise proportioning and efficient mixing of agricultural fertilizers and pesticides through the coordinated arrangement of the mixing tank 1, the medicine storage tank 2, the infusion mechanism 3 and the stirring mechanism. The threaded cooperation between the screw 303 and the first gear 304 in the infusion mechanism 3, and the elastic reset effect of the spring 306, enables the cylinder 301 to accurately extract and transport the medicine or liquid fertilizer. By adjusting the position of the first gear 304 on the screw 303, the proportion of each component can be accurately controlled, thereby achieving the effect of flexibly adjusting the ingredients of the compound preparation according to the formula. At the same time, the one-way valve arrangement on the liquid inlet pipe 307 and the liquid outlet pipe 308 ensures the unidirectional flow of the medicine, avoids backflow and cross contamination of the mixed liquid, and improves the precision and reliability of the dispensing. Moreover, by only setting a drive disk 6, multiple pistons 302 can be driven to move according to different strokes, reducing the number of electrical drive components used, thereby reducing the failure rate and improving the dispensing precision.

[0037] In this embodiment, preferably, the driving disk 6 includes a lifting disk 601 and a plurality of push plates 602. The edge of the lifting disk 601 is provided with a plurality of slots 605, and the plurality of push plates 602 are inserted into the slots 605. The push plates 602 are provided with through holes 603 adapted to the screw rods 303. The diameter of the through holes 603 is larger than the diameter of the screw rods 303, so that the screw rods 303 can pass through the through holes 603. The lifting disk 601 is threaded with a plurality of locking bolts 604 for locking the push plates 602. When the lifting disk 601 moves downward, the locking bolts 604 are locked. When the lifting plate 601 is in motion, the screw 303 gradually extends into the through hole 603. After the push plate 602 contacts the first gear 304, as the lifting plate 601 continues to move downward, the push plate 602 gradually pushes the first gear 304 downward until the piston 302 contacts the bottom inner wall of the cylinder 301; the push plate 602 can be removed from the slot 605, so that when part of the cylinder 301 and the medicine storage tank 2 are not in use, the push plate 602 corresponding to the cylinder 301 can be removed, so that when the lifting plate 601 moves downward, it will not drive the piston 302 in the cylinder 301 to move.

[0038] In this embodiment, preferably, a first electric push rod 4 is fixedly installed at the center of the top of the mixing tank 1, and a tension sensor 5 is fixedly installed at the output end of the first electric push rod 4. The detection end of the tension sensor 5 is fixedly connected to the lifting plate 601, and a first infrared ranging sensor 704 is fixedly installed on the top of the mixing tank 1. The first infrared ranging sensor 704 is used to measure the distance between the lifting plate 601 and the first infrared ranging sensor 704; the lifting plate 601 can be driven to rise and fall by the first electric push rod 4, and through the setting of the tension sensor 5 and the first infrared ranging sensor 704, it can be detected whether the position of the first gear 304 is consistent with the preset value, that is, after the raw material ratio of the agricultural fertilizer and pesticide compound preparation is set, the initial height of each first gear 304 remains fixed, and after the lifting plate 601 contacts the first first gear 304, it is affected by the reaction force of the first gear 304 on the lifting plate 601, and the tension value detected by the tension sensor 5 is The value increases significantly. At this time, the first infrared ranging sensor 704 is used to detect the distance between the lifting plate 601 and the first infrared ranging sensor 704, thereby calculating the initial height of the first contacted first gear 304. After the lifting plate 601 contacts the second first gear 304, the tension value detected by the tension sensor 5 continues to increase significantly, and the first infrared ranging sensor 704 continues to detect the distance between the lifting plate 601 and the first infrared ranging sensor 704, thereby calculating the initial height of the second contacted first gear 304. This process is repeated until the initial heights of all first gears 304 are measured. If, after long-term use, the first gear 304 moves up and down relative to the screw rod 303 and deviates from the initial height, it is detected that the initial height of the first gear 304 has changed. At this time, an alarm can be issued to remind the user to adjust the initial height of the first gear 304, so as to correct it in time and avoid the problem of reduced dispensing accuracy caused by long-term use of the equipment.

[0039] In this embodiment, preferably, the stirring mechanism includes a third motor 9, a stirring shaft 10 rotatably installed inside the mixing tank 1 and two sets of stirring blades 11 fixedly mounted on the stirring shaft 10. The third motor 9 is fixedly installed at the bottom end of the mixing tank 1, and the stirring shaft 10 can be driven to rotate by the third motor 9. When the stirring shaft 10 rotates, the stirring blades 11 are driven to rotate, thereby mixing the raw materials in the mixing tank 1; a premixing chamber 12 is provided at the top of the inner cavity of the mixing tank 1, and the stirring blades 11 located above are located in the premixing chamber 12. A plurality of drainage holes 1201 are provided at the bottom of the premixing chamber 12, and the liquid outlet pipe 3 The bottom end of 08 extends into the premixing chamber 12, and the water inlet 101 is connected to the premixing chamber 12 through a pipeline; through the setting of the premixing chamber 12, the raw materials and water input into the mixing tank 1 first enter the premixing chamber 12, and are stirred by the stirring blades 11 in the premixing chamber 12, so that the raw materials and water entering the premixing chamber 12 are first premixed, and the raw materials entering the bottom of the mixing tank 1 can be preliminarily mixed evenly, and then, in the process of configuring the agricultural fertilizer and pesticide compound preparation, the agricultural fertilizer and pesticide compound preparation can be discharged through the liquid outlet 103. At this time, the accuracy of the raw material ratio of the agricultural fertilizer and pesticide compound preparation can also be guaranteed, so as to facilitate emergency use.

[0040] In this embodiment, preferably, a touch panel 13 is provided on the top of the mixing tank 1, and the ratio between the raw materials can be manually input through the touch panel 13 to automatically mix the ingredients according to the ratio. A processor and a control module are provided in the touch panel 13, and the control module is connected to the signals of electrical components such as the first motor 702, the second motor 711, the third motor 9, and the first electric push rod 4 to receive and send signals to control the operation of each electrical component.

[0041] See also Figures 5 to 7703, a second gear 703 is fixedly mounted on the top of the mixing tank 1, and the second gear 703 is fixedly mounted on the top of the mixing tank 1. A second infrared ranging sensor 8 is fixedly installed on the side away from the second electric push rod 705, and the second infrared ranging sensor 8 is used to detect the distance between the first gear 304 and the second infrared ranging sensor 8; the driving assembly includes a rotating ring 708, a ring gear 709 fixedly mounted on the rotating ring 708, and a third mounting bracket 710 fixedly mounted on the top of the mixing tank 1, the rotating ring 708 is rotatably connected to the top wall of the mixing tank 1, the second mounting bracket 706 is fixedly mounted on the rotating ring 708, and a second motor 711 is fixedly installed on the top of the third mounting bracket 710, and a third gear 712 meshing with the ring gear 709 is fixedly mounted on the output end of the second motor 711. The third gear 712 can be driven to rotate by the second motor 711. When the third gear 712 rotates, the rotating ring 708 is driven to rotate through the ring gear 709. When the rotating ring 708 rotates, the second mounting bracket 706 is driven to rotate, thereby realizing that the second mounting bracket 706 is driven to move in a circular trajectory by the driving assembly;When the initial height deviation of the first gear 304 is detected, the second mounting bracket 706 is driven by the driving assembly to move in a circular trajectory. When the second mounting bracket 706 moves, the second infrared ranging sensor 8 is driven to move via the first mounting bracket 701. When the second infrared ranging sensor 8 moves, it detects the distance between the first gear 304 and the second infrared ranging sensor 8. If the position deviation of the first gear 304 is detected, the output end of the second electric push rod 705 is controlled to extend to drive the second gear 703 to move, so that the second gear 703 engages with the first gear 304. The second gear 703 is then driven to rotate by the first motor 702, thereby driving the first gear 304 to rotate. When the first gear 304 rotates, it rises and falls relative to the screw 303 until the first gear 304 moves to a preset initial height, thereby automatically correcting the first gear 304 when the first gear 304 is offset. In addition, after the ratio of each raw material is input through the touch panel 13, the initial height of each raw material corresponding to the first gear 304 can be automatically calculated, so that the initial height of each first gear 304 can be automatically adjusted by the adjustment mechanism 7. ;

[0042] Working principle: The present invention realizes the calculation of the ratio of each raw material and the mixing of ingredients according to the ratio, relying on the coordinated operation of the intelligent design of the system and the mechanical structure. The user inputs the ratio data between the raw materials of agricultural fertilizers and pesticides through the touch panel 13 on the top of the mixing tank 1. The system automatically converts the initial height of each raw material corresponding to the first gear 304 based on the structural parameters such as the pitch of the screw 303 and the stroke of the piston 302 in the infusion mechanism 3, using a preset algorithm, and completes the digital calculation and conversion of the ratio parameters.

[0043] In the batching execution link, the adjustment mechanism 7 plays a key role. Driven by the driving component, the second mounting bracket 706 makes a circular motion along the top of the mixing tank 1, driving the second infrared ranging sensor 8 to scan and detect the actual height of each first gear 304. Once a deviation is detected between the actual height and the preset height calculated by the system, the second electric push rod 705 immediately pushes the second gear 703 to engage with the offset first gear 304, and then the first motor 702 drives the second gear 703 to rotate. By utilizing the thread matching characteristics of the first gear 304 and the screw 303, the first gear 304 is accurately adjusted to the preset position to complete the initial calibration of each raw material ratio.

[0044] When the actual batching is carried out, the first electric push rod 4 drives the driving disk 6 to move downward, and the push plate 602 contacts each first gear 304 in turn during the descent process. During this period, the tension sensor 5 and the first infrared ranging sensor 704 work closely together to monitor the contact sequence and position information of the first gear 304 in real time, and compare and verify with the preset ratio data. When the first gear 304 is pushed downward by the push plate 602, it drives the piston 302 to compress the liquid raw material in the cylinder 301. Under the action of the first one-way valve 309 and the second one-way valve 310, the raw material is input into the premixing chamber 12 of the mixing tank 1 through the liquid outlet pipe 308 according to the preset proportion; at the same time, the water inlet 101 accurately controls the water inlet through the electronic flow meter 102, so that the input speed of each raw material and the input speed of water strictly match the formula requirements, ensuring that the raw materials are mixed in proportion.

[0045] In addition, the system also has an error compensation function. During the long-term use of the equipment, if the first gear 304 is offset due to reasons such as device vibration, the system will automatically perform a detection and correction process before each batching to avoid the accumulation of proportion errors caused by the position change of the first gear 304, thereby ensuring that the proportion accuracy of the agricultural fertilizer and pesticide compound preparations always meets the requirements; and the design of the premixing chamber 12 and the stirring blade 11 can enable the raw materials and water entering the mixing tank 1 to be preliminarily mixed first, further ensuring that the output compound preparation has uniform composition and accurate proportions.

[0046] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
