Description

Technical Field

[0001] This invention belongs to the field of agricultural sprayer technology, specifically relating to an electric strip-and-row sprayer for soybean-corn strip intercropping. Background Technology

[0002] my country is a major soybean consumer, but its self-sufficiency rate has long been low, resulting in a high dependence on imports. Soybean-corn strip intercropping can increase soybean planting area and yield with limited arable land resources, helping to improve my country's soybean self-sufficiency and reduce reliance on imported soybeans. For example, some regions have achieved significant increases in soybean production through this planting model, providing strong support for local soybean supply.

[0003] With the continuous development of agricultural technology, the soybean-corn strip intercropping model has gradually become widely used. In this model, soybeans and corn are planted at specific row ratios and intervals to improve land utilization and grain yield. However, traditional spraying devices often suffer from uneven spraying, potential phytotoxicity to non-target crops, and low operational efficiency when applying pesticides to soybean-corn strip intercropping. Due to the significant differences in the growth characteristics of soybeans and corn, traditional spraying systems cannot be precisely adjusted according to the different heights, densities, and growth stages of the crops. This results in the spraying range not accurately covering the required areas of the crops and is prone to improper or excessive spraying of the sides of soybeans or corn, thus affecting the effectiveness of pesticide application.

[0004] Furthermore, existing sprayers used in soybean-corn intercropping generally employ a fixed spray width and angle, which cannot be adjusted according to differences in crop height, spacing, or crop growth cycle. This limitation results in significant differences in spraying effectiveness between soybeans and corn, and makes precise application difficult. In particular, when corn plants are tall, existing spraying equipment cannot effectively cover the sides of the corn, thus affecting spraying efficiency and even wasting pesticides.

[0005] Therefore, there is a need for a spraying device specifically designed for soybean-corn strip intercropping that can flexibly adjust the spray width, spray angle, and spray direction according to different growth stages of crops, differences in crop height, and planting spacing, in order to improve the effectiveness of pesticide application and operational efficiency.

[0017] The beneficial effects of this invention are as follows: 1. Improved spraying accuracy: Through the design of the row spray boom control system, combined with image processing technology, the sprayer can monitor and digitally process crop row curvature information in real time, precisely control the spraying position, and achieve precise row-to-row spraying of soybeans and corn strips. This intelligent adjustment ensures that the pesticide is applied only to the target crop, avoiding phytotoxicity to non-target crops.

[0018] 2. Improved Operational Efficiency: This sprayer, through its electric push-rod adjustment system, can automatically adjust the extension and retraction of the spray boom frame according to the crop height and strip planting spacing, greatly improving operational efficiency. Especially when the spacing between soybean and corn strips changes, the sprayer can flexibly adapt, ensuring continuous and efficient spraying operations.

[0019] 3. Reduced pesticide waste: This sprayer effectively avoids pesticide waste through precise nozzle assembly and adjustment and intelligent row alignment.

[0020] 4. Enhanced Adaptability and Flexibility: This sprayer is designed to adapt to variations in planting width, crop height, and row spacing. When the spacing between soybean and corn strips changes, the side spray boom automatically adjusts the spray width to adapt to complex planting environments and achieve precise crop application. Furthermore, the adjustable and detachable nozzle assembly greatly enhances the equipment's adaptability. The vertical flipping function of the side spray boom allows the spray system to automatically adjust the spray angle and width according to the crop's growth stage or planting pattern, providing a more flexible spraying solution. Especially when soybeans and corn are intercropped, the spray width and angle can be adjusted to meet the spraying needs of different crops.

[0021] 5. Improved operational mobility: The electric push rod's lifting function allows the sprayer to spray at different plant heights, ensuring smooth operation even in complex terrain and densely cropped environments, thus improving operational mobility and adaptability. Flexible adjustments to various spraying modes enable precise coverage of the desired crop areas, improving spraying effectiveness and efficiency, reducing waste of pesticides or fertilizers, and saving on pesticide costs.

[0022] 6. Stability of the Tilting Support System: The design of the tilting block, spring, and tilting support shaft ensures the stability and reliability of the spray system during the tilting process. The tilting block tilts freely and is supported by the elasticity of the spring, ensuring smooth movement of the upper slide rod, avoiding over-tilting or operational errors, and improving the operational safety of the system.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Example 1: An electric strip-and-row boom sprayer for soybean-corn strip intercropping aims to improve spraying accuracy and operational efficiency, reduce unnecessary pesticide waste, and achieve precise and efficient pesticide application. To achieve the above technical objectives, such as... Figure 1 As shown, the sprayer mainly includes a frame 4, a lateral adjustment spray boom system, and a row spray boom control system. The frame is equipped with wheels 13 at the bottom. The frame 4 is fixed with a steering wheel 10, a sprayer water pump controller 8, a hydraulic operating lever 9, a driver's seat 7, a medicine tank 6, a diesel engine 5, a three-cylinder plunger pump 3, a generator 15, a hydraulic oil tank 12, and an image processor 14. The diesel engine 5 is connected to the generator 15 and the three-cylinder plunger pump 3 via a belt. Since the sprayer uses the diesel engine 5 and the generator 15 for range extension instead of using a conventional engine as the power source, the ability to operate continuously is greatly improved.

[0035] like Figure 2 As shown, the lateral adjustment spray bar system includes a spray bar mechanism 1, a first electric actuator 1015, and a second electric actuator 1012. The spray bar mechanism 1 consists of a central spray bar frame 1011, a side spray bar frame 1013, a corn nozzle assembly, and a soybean nozzle assembly. The corn assembly is fixed below the side spray bar frame via a square tube fixing plate 103. The soybean assembly is fixed to the central spray bar frame 1011 in the same manner. The connection between the central spray bar frame 1011 and the side spray bar frame 1013 is as follows: The upper and lower sliding rods on the side spray boom frame 1013 are directly inserted into the upper and lower longitudinal beams of the middle spray boom frame 1011. The two ends of the second electric push rod 1012 are connected to the upper and lower sliding rods of the middle spray boom frame 1011 and the side spray boom frame 1013, respectively. With the help of the second electric push rod 1012, the side spray boom frame can move telescopically relative to the middle spray boom frame 1011. This not only enables precise alignment of the corn belt, but also allows for flexible adjustment of the working width of the sprayer, thus achieving controllability of the working area.

[0036] like Figure 4-5 As shown, the intermediate spray bar frame 1011 has two top longitudinal beams in the middle, and two sliders 101 are fixed directly below each top longitudinal beam. The intermediate spray bar frame 1011 is connected to two slide rails 102 set on the lifting frame through the sliders 101. The two first electric push rods 1015 are connected to the upper part of the lifting frame and the side spray bar frame, respectively. With the help of the first electric push rods 1015, the intermediate spray bar frame 1011 with the sliders 101 fixed can move parallel on the slide rails 102, and at the same time drive the lateral movement of the soybean nozzle assembly below, thereby completing the precise alignment of the soybean belt.

[0037] like Figure 3 As shown, in the electric strip-type row-to-row sprayer for soybean-corn intercropping, the soybean nozzle assembly consists of four soybean nozzles 108, a spray pipe fixing component 107, a square tube fixing plate 103, an adjusting spray bar vertical beam 1014, bolts, and a soybean spray pipe 109. The four soybean nozzles 108 are respectively fixed on the soybean spray pipe 109. One end of the adjusting spray bar vertical beam 1014 is connected to the spray pipe fixing component 107 by bolts, and the other end is fitted into the fixing beam and fixed by bolts. There are two side spray bar frames 1013, which include the corn nozzle assembly. The components and connection methods are the same as those of the soybean nozzle assembly. Before operation, the nozzles installed on the spray pipe can be pre-adjusted according to the actual row spacing of the crops to determine the installation distance between the nozzles. This achieves the advantages of adjustable and detachable nozzle assembly with strong adaptability.

[0038] To further explain, since the spacing between the corn strip and the soybean strip inevitably varies during planting, traditional sprayers cannot adjust to changes in spacing during spraying operations, resulting in the inability to spray the corn strip within a certain width. The electric strip-and-row sprayer for soybean-corn strip intercropping can utilize the flexible extension and retraction of the side spray bar frame 1013 to automatically adjust the corn nozzle 106 left and right when the spacing between the corn strip and the soybean strip changes, thus completing precise row-and-row spraying of the corn strip.

[0039] In the aforementioned electric strip-and-row sprayer for soybean-corn strip intercropping, the vertical lifting of the spray bar mechanism is achieved by the reciprocating extension and retraction of the lifting electric push rod 202 in the lifting frame 2, thereby enabling spraying of plants at different heights and improving the passability and adaptability of the operation.

[0040] The electric row-splitting sprayer for soybean-corn strip intercropping is characterized by its row-splitting control system, which mainly consists of an image acquisition device and an image processor 14. The image acquisition device includes an industrial camera mounting bracket and an industrial camera 1010, which is mounted directly in front of the sprayer frame for better image acquisition of the crops. Using the industrial camera 1010, the bending information of the crop rows can be transmitted to the image processor in real time for digital processing and to generate a feedback signal. Upon receiving the signal, the electric actuator extends and retracts, driving the sprayer frame to move laterally, thus achieving precise row-splitting spraying of the soybean and corn rows.

[0041] During operation, the pre-set operating height of the spray boom mechanism 1 needs to be determined in advance based on the height of the soybean and corn plants, using the lifting electric actuator 202. The soybean nozzle 108 and corn nozzle 106 are installed directly above the corresponding crop rows. Simultaneously, the sprayer water pump controller 8 is activated, drawing soybean and corn pesticides from the two pesticide tanks 6 via a three-cylinder plunger pump 3 and transmitting them to the corn nozzle 106 and soybean nozzle 108 through flexible hoses, thus achieving normal pesticide spraying. The image processor 14 and industrial camera 1010 are then activated. The industrial camera 1010 transmits real-time crop row bending and weed information to the image processor 14, extracting crop row information based on deep learning algorithms and performing digital processing to generate feedback signals. These signals are then sent to the first electric actuator 1015 and the second electric actuator 1012, controlling their extension and retraction. Because the control signals for the electric actuators are separate and adjustable, the independent and overall movement of the central spray boom frame 1011 and the side spray boom frame 1013 can be achieved. This not only enables automatic and precise row-to-row spraying of soybean strips, but also, when there is a difference in the spacing between the soybean and corn strips, it drives the corn nozzle 106 to automatically adjust the left and right alignment of the corn strip, thus achieving automatic and precise row-to-row spraying of the corn strip. Depending on the different growth conditions of the crops, their heights will vary. This spray boom mechanism can adjust up and down in a timely manner according to the crop height, and can also change the spray width in real time to cope with planting environments of varying widths. Furthermore, when spraying a single crop, the individual nozzle components can be flexibly adjusted to achieve net-field spraying, demonstrating strong adaptability.

[0042] The sprayer in this embodiment not only improves the accuracy and efficiency of spraying, but also effectively reduces pesticide waste and enhances its adaptability to different planting environments, resulting in significant economic benefits and environmental protection.

[0043] Example 2: Based on Example 1, the side spray boom bracket is equipped with a vertical flipping function. Specifically, as shown... Figure 1 and Figure 2 As shown, the side spray boom frame 1013 includes a lower sliding rod 1022 and an upper sliding rod 1033, which are fixed together by a frame. The middle spray boom frame 1011 includes a lower longitudinal beam 1020, an upper longitudinal beam 1034, a bottom crossbeam 1017, and an end frame.

[0044] A lower longitudinal beam 1020 is provided at the bottom of the intermediate spray boom frame 1011, and an upper longitudinal beam 1034 is provided at the top. A lower track groove 1021 is provided on the inner side wall of the lower longitudinal beam 1020, and an upper track groove 1035 is provided on the inner side wall of the upper longitudinal beam 1034. The lower sliding rod 1022 is fitted into the lower track groove 1021.

[0045] A side sliding post 1036 is fitted inside the upper track groove 1035, and a flipping block 1037 is provided between the two side sliding posts 1036. The two sides of the flipping block 1037 are assembled into the shaft holes of the corresponding side sliding posts 1036 through the end shaft 1038. Thus, the flipping block 1037 can be freely flipped along the end shaft 1038.

[0046] A spring 1039 is fitted inside the upper track groove 1035. A spring seat is provided at the inner end of the spring 1039, and the spring seat is fixed to the inner wall of the upper longitudinal beam 1034. The outer end of the spring 1039 is supported on the inner wall of the side sliding column 1036. Parallel through holes are provided on the flip block 1037, and the upper sliding rods 1033 are respectively fitted into the corresponding through holes.

[0047] An adjusting spray bar vertical beam 1014 is fixed on the upper slide bar 1033. A corn spray pipe 105 is fixed at the bottom of the adjusting spray bar vertical beam 1014. A corn spray head 106 is installed on the corn spray pipe 105. The corn spray pipe 105 is connected to the liquid supply pipeline.

[0048] A bottom crossbeam 1017 is fixed to the lower longitudinal beam 1020. A support base 1018 is fixed to the bottom of the bottom crossbeam 1017. A third electric actuator 1019 is hinged to the front side of the support base 1018. The distal push rod of the third electric actuator 1019 is hinged to the push-pull shaft 1023 of the side spray boom frame 1013. The push-pull shaft 1023 is fixed to the inner end of the sliding rod 1022.

[0049] A U-shaped auxiliary beam 1030 is fixedly placed at the end of the lower longitudinal beam 1020. A side support plate 1031 is fixed to the outside of the U-shaped auxiliary beam 1030. An inclined groove is provided on the side support plate 1031, which includes an inner inclined surface 1027 at the near end and an outer surface 1028 at the far end. A flip support shaft 1029 is provided at the top of the outer surface 1028. A U-shaped seat 1026 is fixed to the outer end of the flip support shaft 1029.

[0050] Based on the above structure, this embodiment can achieve the following: Figure 9 The three state changes shown are: the side spray boom 1013 expanding outwards, the side spray boom 1013 retracting inwards, and the side spray boom 1013 flipping vertically. For example... Figure 6 As shown, if the width of the middle spray boom 1011 is *a* and the width of the side spray boom 1013 is *b*, then the length of the width *l* of the entire spray frame is *a* ≤ *l* ≤ *a* + 2*b*. Therefore, the width range it can cover for soybean spraying is *a* to *a* + 2*b*. Alternatively, when soybeans and corn are intercropped, the soybeans with a width of *a* in the middle are sprayed in conjunction with the corn on both sides with a width of *b*. Or, when there is a height difference between corn and soybeans, the width range for spraying the corn on both sides can be *b* respectively. Figure 9As shown in Figure ①, when the corn plants have grown significantly taller, the side spray boom 1013 is in an upright position with a height range of b, allowing for side spraying of the corn. The vertical flipping function of the side spray boom enables the spraying system to automatically adjust the spray angle and width according to the crop's growth stage or planting pattern, providing a more flexible spraying solution. Especially when soybeans and corn are intercropped, the spray width and angle can be adjusted to meet the spraying needs of different crops.

[0051] The extension and retraction of the side spray boom can be controlled by the extension and retraction of the third electric actuator, thereby precisely adjusting the spray width to ensure that the spray range matches the crop's growth status, reducing resource waste and improving spraying efficiency. Figure 9 As shown in Figure ②, when the third electric actuator 1019 is extended forward, the side spray boom 1013 in the retracted state can be changed to the extended state; conversely, when the third electric actuator 1019 is retracted, the side spray boom 1013 in the extended state can be changed to the retracted state. Figure 9 As shown in Figure ①, in the extended state, when the end of the third electric actuator 1019 continues to move outward, the push-pull shaft 1023 is constrained by the inclined guide rod 1025, causing the push-pull shaft 1023 to slide downward along the inclined surface of the inclined guide rod 1025 and enter the inclined groove. Simultaneously, under the support of the flip support shaft 1029, the sliding rod 1022 is forced to flip upward. Finally, the push-pull shaft 1023 falls to the bottom of the groove formed by the inclined surface. A limit rod 1032 is fixed at the top of the lower track groove 1021 as a stop to prevent the side spray boom frame 1013 from flipping inward excessively.

[0052] During the upward rotation of the flip support shaft 1029, the entire side spray bar bracket 1013 rotates along the axis of the push-pull shaft 1023. This causes the upper slide bar 1033 to also rotate upward. As the upper slide bar 1033 rotates, it slides along the through hole of the flip block 1037. Simultaneously, the rotated upper slide bar 1033 pushes the flip block 1037 inward, thereby compressing the spring 1039 through the side slide post 1036. Finally, the flip block 1037 elastically presses against the outside of the upper slide bar 1033. Figure 9 In the diagram, d1, d2, and d3 represent the lengths of different springs 1039. The design of the flipping block, spring, and flipping support shaft ensures the stability and reliability of the spray system during the flipping process. The flipping block can flip freely and is supported by the elasticity of the spring, ensuring smooth movement of the upper slide rod, avoiding excessive flipping or operational errors, and improving the operational safety of the system.

[0053] This spraying system not only avoids over-application and reduces pesticide waste, but also improves the uniformity and accuracy of spraying, ensuring precise application of pesticides or fertilizers and enhancing the overall efficiency of agricultural production. The system achieves flipping and adjustment functions through the cooperation of multiple structural components, featuring a simple design and intuitive operation. The sloping grooves and limiting rods effectively guide the movement of the spray frame, reducing complex operating steps, lowering the possibility of malfunctions, and facilitating daily maintenance and operation. Through flexible adjustments of multiple spraying modes, it can accurately cover the required areas of the crop, improving spraying effect and efficiency, reducing waste of sprayed pesticides or fertilizers, and saving on pesticide usage costs.

[0054] Based on the above scheme, the operation process of the spray system with the added vertical flipping function of the side spray boom frame is as follows. First, ensure that all components of the spray frame are installed properly, especially key components such as the electric actuator, push-pull shaft, spring, and flipping block. Check whether the liquid path is unobstructed and whether the corn spray pipe is securely connected. After the system is ready, the spray frame is in good working condition to ensure that the spraying operation can be carried out smoothly. Then, according to the growth stage of the crop and the area to be sprayed, use the controller to adjust the extension and retraction of the third electric actuator 1019 to adjust the side spray boom frame 1013 to the extended or retracted state. At this time, the spraying system can adjust the spray width according to the crop width or plot requirements to ensure that the spraying range covers the required area of ​​the crop, avoid over-spraying or omissions, and improve spraying efficiency. When the crop, such as corn, is relatively tall, or needs to be sprayed from the side, activate the third electric actuator 1019 to control the side spray boom frame to flip vertically. Guided by the push-pull shaft 1023 and the inclined guide rod 1025, the side spray boom frame flips to the appropriate position along the flipping support shaft 1029. The spray gun can be adjusted to an upright position during the flipping process (e.g., Figure 9 As shown in ①, the corn spray pipe can spray from the side, adapting to the spraying needs of tall crops such as corn and ensuring uniform spraying and coverage. By operating accessories such as the flip block 1037 and spring 1039, the spraying angle can be further adjusted so that the corn spray pipe 105 can be precisely aimed at the crop, avoiding waste. If more precise spraying is required, the spray width and spraying angle can be further adjusted according to the crop height and growth status. After completing the spraying task, the controller is used to retract the third electric push rod 1019, so that the side spray bar frame returns from the vertical position to the original horizontal position. At this time, the push-pull shaft 1023, driven by the inclined guide rod 1025, re-enters the lower track groove 1021, and the side spray bar frame returns to the initial state. The system returns to the retracted state, which facilitates the storage or transfer of the equipment to the next spraying area, reduces the space occupied, and ensures equipment safety.

[0055] After each use, check the wear condition of all components of the spray system to ensure that there are no abnormalities in parts such as springs, slide rails, and tilting blocks, that the hydraulic lines are unobstructed, and that the electric actuator is functioning properly. Regular inspection and maintenance help extend the service life of the equipment and ensure that the spray system is in optimal working condition every time it is used.

[0056] The specific embodiments described above are merely illustrative or explanatory of the principles of the present invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the present invention should be included within the protection scope of the present invention.
