Description

Technical Field

[0001] The invention belongs to the technical field of agricultural sprayers, and in particular relates to an electric belt-dividing row spray boom sprayer for soybean-corn belt-shaped composite planting. Background Art

[0002] my country is a major soybean consumer, but its soybean self-sufficiency rate has been low for a long time, and its dependence on foreign countries is high. Soybean-corn strip compound planting can increase the planting area and yield of soybeans under limited arable land resources, which will help improve my country's soybean self-sufficiency and reduce dependence on imported soybeans, thereby ensuring the country's food security strategy. For example, some regions have achieved a significant increase 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-composite planting model has gradually been widely used. In this planting model, soybeans and corn are planted at a certain row ratio to improve land utilization and grain yield. However, when applying pesticides to soybean-corn strip-composite planting, traditional spray devices often have problems such as uneven spraying, easy pesticide damage to non-target crops, and low operating efficiency. Due to the large differences in the growth characteristics of soybeans and corn, traditional spray systems cannot be accurately adjusted according to the different heights, densities and growth stages of crops, resulting in the spraying range cannot accurately cover the required area of ​​the crop, and it is easy to spray improperly or overspray on the sides of soybeans or corn, thus affecting the effect of pesticide application.

[0004] In addition, existing sprayers generally use fixed spray width and fixed spray angle designs in soybean-corn intercropping, and cannot adjust the spray angle and spray width according to crop height differences, spacing changes, or crop growth cycles. This limitation causes a large difference in spray effect between soybeans and corn, and it is difficult to achieve precise spraying, especially when the corn plants are tall, the existing spray equipment cannot effectively cover the sides of the corn, which affects the spraying effect and even wastes the spray agent.

[0005] Therefore, a spraying equipment specifically for soybean-corn strip composite planting is needed, which can flexibly adjust the spray width, spray angle and spray direction according to the different growth stages of crops, crop height differences and planting spacing to improve the application effect and work efficiency.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1: A soybean-corn strip-shaped composite planting electric strip-row sprayer, with the purpose of improving spray accuracy and operation efficiency, reducing unnecessary drug waste, and achieving accurate and efficient spraying of pesticides. To achieve the above technical objectives, Figure 1 As shown, the sprayer mainly includes a frame 4, a lateral adjustment spray boom system, a row spray boom control system and other main components; a wheel 10 is arranged at the bottom of the frame, and a steering wheel 10, a sprayer water pump controller 8, a hydraulic operating lever 9, a driver's seat 7, a medicine box 6, a diesel engine 5, a three-cylinder plunger pump 3, a generator 15, a hydraulic oil tank 12 and an image processor 14 are fixed to the frame 4. The diesel engine 5 is connected to the generator 15 and the three-cylinder plunger pump 3 through a belt. Since the sprayer is extended by the diesel engine 5 and the generator 14, it does not use a conventional engine directly as a power source, which greatly improves the ability of continuous operation.

[0027] like Figure 2As shown, the lateral spray boom adjustment system has a spray boom mechanism 1 and a first electric push rod 1015, a second electric push rod 1012, wherein the spray boom mechanism 1 is composed of an intermediate spray boom frame 1011 and a side spray boom frame 1013, a corn nozzle assembly and a soybean nozzle assembly, the corn assembly is fixed to the lower side spray boom frame through a square tube fixing cross plate 103, and the soybean assembly is fixed to the intermediate spray boom frame 1011 in the same way, and the connection between the intermediate spray boom frame 1011 and the side spray boom frame 1013 is , the upper and lower sliding bars on the side spray rod frame 1013 are directly inserted into the upper and lower longitudinal beams of the middle spray rod frame 1011, and the two ends of the second electric push rod 1012 are respectively connected to the upper and lower sliding bars of the middle spray rod frame 1011 and the side spray rod frame 1013. With the help of the second electric push rod 1012, the telescopic movement of the side spray rod frame relative to the middle spray rod frame 1011 can be realized, which can not only complete the precise row alignment of the corn belt, but also can flexibly adjust the operating width of the sprayer, thereby realizing the controllability of the operating area.

[0028] like Figure 4-5 As shown, there are two top longitudinal beams in the middle of the middle spray boom frame 1011, and two sliders 101 are fixed directly below each top longitudinal beam. The middle spray boom frame 1011 is connected to two slide rails 102 arranged on the lifting frame through the sliders 101; the two ends of the two first electric push rods 1015 are respectively connected to the lifting frame and the upper part of the side spray boom frame. With the help of the first electric push rods 1015, the middle spray boom frame 1011 fixed with the sliders 101 can achieve parallel movement 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.

[0029] like Figure 3 As shown, in the electric belt-to-row spray boom sprayer for the soybean-corn strip composite planting, the soybean spray head assembly consists of four soybean spray heads 108, a spray pipe fixing part 107, a square tube fixing horizontal plate 103, an adjusting spray boom vertical beam 1014, bolts, and a soybean spray pipe 109. The four soybean spray heads 108 are fixed on the soybean spray pipe 109 respectively. One end of the adjusting spray boom vertical beam 1014 is connected to the spray pipe fixing part 107 by a bolt, and the other end is inserted into the fixed beam and fixed by a bolt. There are two side spray boom frames 1013, which include the corn spray head assembly. The components and connection methods are the same as the soybean spray head assembly. Before the operation, the spray heads installed on the spray pipe can adjust the installation distance between the spray heads in advance according to the actual row spacing of the crop. The advantages of the adjustable and detachable spray head assembly and strong adaptability are achieved.

[0030] It is further explained that since the spacing between the corn belt and the soybean belt will inevitably differ during planting, the traditional sprayer cannot adjust with the change of spacing during the spraying operation, resulting in the inability to spray the corn belt within a width normally. The electric strip-to-row spray boom sprayer for the composite planting of soybean and corn strips can utilize the flexible telescopic characteristics of the side spray boom frame 1013. When the spacing between the corn belt and the soybean belt changes, it drives the corn nozzle 106 to automatically adjust the rows left and right, thereby completing the precise row spraying of the corn belt.

[0031] In the electric belt-row sprayer for soybean-corn strip-shaped composite planting, the vertical lifting of the spray bar mechanism is achieved by the back-and-forth telescopic movement of the lifting electric push rod 202 in the lifting frame 2, thereby achieving spraying of plants at different heights, thereby improving the passability and adaptability of the operation.

[0032] The electric strip-type row-by-row spray boom sprayer for the strip-type composite planting of soybean and corn is characterized in that the row-by-row spray boom control system mainly includes an image acquisition device and an image processor 14. The image acquisition device mainly includes an industrial camera mounting frame and an industrial camera 1010. The industrial camera 1010 is installed in front of the spray boom frame to better read the image of the crop. With the help of the industrial camera 1010, the crop row bending information can be transmitted to the image processor in real time, and digital processing is performed to generate a feedback signal. After receiving the signal, the electric push rod performs telescopic movement and drives the lateral movement of the spray boom frame to complete the precise row spraying of the soybean and corn rows.

[0033] During operation, according to the height of soybean and corn plants, the pre-height of the spray rod mechanism 1 needs to be set in advance under the action of the lifting electric push rod 202. The soybean nozzle 108 and the corn nozzle 106 are installed directly above the corresponding crop rows. At the same time, the sprayer water pump controller 8 is started, and the soybean agent and corn agent respectively installed in the two medicine boxes 6 are extracted by the three-cylinder plunger pump 3, and transmitted to the corn nozzle 106 and the soybean nozzle 108 with the help of a hose to achieve normal spraying of the agent. Turn on the image processor 14 and the industrial camera 1010. With the help of the industrial camera 1010, the crop row bending information and weed information can be transmitted to the image processor 14 in real time, and the crop row information is extracted and digitized based on the deep learning algorithm to generate a feedback signal, and the signal is sent to the first electric push rod 1015 and the second electric push rod 1012 respectively to control the telescopic movement of the electric push rod. Since the control signal of the electric push rod is separate and adjustable, the independent movement and overall movement of the middle spray rod frame 1011 and the side spray rod frame 1013 can be realized, which can not only realize the automatic and precise row spraying of the soybean belt, but also drive the corn nozzle 106 to complete the automatic left and right row adjustment of the corn belt when there is a difference in the spacing between the soybean belt and the corn belt, and complete the automatic and precise row spraying of the corn belt. According to the different growth conditions of the crops, their heights will be different. The spray rod mechanism can be adjusted up and down in time according to the height of the crops, and the spray width can be changed in real time in the face of planting environments of varying widths. In addition, when spraying a single crop, each nozzle assembly can be flexibly adjusted to complete the net spraying of the crop, which has strong adaptability.

[0034] The sprayer of this embodiment not only improves the accuracy and operating efficiency of spraying, but also effectively reduces the waste of pesticides, enhances the adaptability to different planting environments, and has significant economic benefits and environmental protection effects.

[0035] Embodiment 2: Based on Embodiment 1, the side spray rod frame is provided with a vertical flip function. Figure 1 and Figure 2 As shown, the side spray rod frame 1013 includes a lower sliding rod 1022 and an upper sliding rod 1033, which are fixed as a whole through a frame. The middle spray rod frame 1011 includes lower longitudinal beams 1020, 1034 and 1017, and an end frame.

[0036] A lower longitudinal beam 1020 is provided at the bottom of the middle spray rod frame 1011, 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 slide bar 1022 is matched and sleeved in the lower track groove 1021.

[0037] A side sliding column 1036 is mounted in the upper track groove 1035, and a flip block 1037 is arranged between the side sliding columns 1036 on both sides. The two sides of the flip block 1037 are assembled in the shaft holes of the corresponding side sliding columns 1036 through the end shaft 1038. Therefore, the flip block 1037 can be freely flipped along the end shaft 1038.

[0038] A spring 1039 is mounted in the upper rail groove 1035, a spring seat is arranged at the inner end of the spring 1039, the spring seat is fixed to the inner wall of the upper longitudinal beam 1034, and the outer end of the spring 1039 is supported on the inner wall of the side sliding column 1036. Parallel through holes are arranged on the flip block 1037, and the upper sliding rods 1033 are matched and mounted in the corresponding through holes.

[0039] An adjusting spray boom vertical beam 1014 is fixed on the upper slide bar 1033 , a corn spray pipe 106 is fixed at the bottom of the adjusting spray boom vertical beam 1014 , a corn spray pipe 105 is installed on the corn spray pipe 106 , and the corn spray pipe 105 is connected to the liquid supply pipeline.

[0040] A bottom crossbeam 1017 is fixed to the lower longitudinal beam 1020, 1018 is fixed to the bottom of the bottom crossbeam 1017, a third electric push rod 1019 is hinged to the front side of 1018, and the distal push rod of the third electric push rod 1019 is hinged to the push-pull shaft 1023 of the side spray rod frame 1013. A push-pull shaft 1023 is fixed to the inner end of the lower sliding rod 1022.

[0041] A U-shaped auxiliary beam 1030 is fixed below the end of the lower longitudinal beam 1020, a side support plate 1031 is fixed outside the U-shaped auxiliary beam 1030, an inclined groove is provided on the side support plate 1031, and the inclined groove includes an inner inclined surface 1027 at the proximal end and an outer facade 1028 at the distal end, and a flip support shaft 1029 is provided at the top of the outer facade 1028. A U-shaped seat 1026 is fixed at the outer end of the flip support shaft 1029.

[0042] Based on the above structure, this embodiment can achieve the following Fig. 9 The three state changes shown are: the side spray rod frame 1013 expands outward, the side spray rod frame 1013 retracts inward, and the side spray rod frame 1013 flips vertically. Figure 6 As shown, if the width of the middle spray boom frame 1011 is a, and the width of the side spray boom frame 1013 is b, then the length of the width l of the entire spray rack is, a≤l≤a+2b, so that it can cover the soybean spraying width range of a to a+2b; or, when soybeans and corns are interplanted, the soybeans with a middle width of a and the corns with a width of b on both sides are sprayed; or, when there is a height difference between corns and soybeans, the width range of the corns on both sides that can be sprayed separately is b. Fig. 9As shown in ①, when the corn plant becomes significantly taller, the side spray rod frame 1013 is in an upright state, and its height range is b, and the corn can be sprayed from the side. The vertical flip function of the side spray rod frame enables the spray system to automatically adjust the spray angle and spray width according to the growth stage or planting pattern of the crop, providing a more flexible spraying solution. Especially when soybeans and corn are interplanted, the spraying needs of different crops can be met by adjusting the spraying width and angle.

[0043] Through the telescopic control of the third electric push rod, the side spray rod frame can be extended and retracted, so as to accurately adjust the spraying width, ensure that the spray range matches the crop growth status, reduce resource waste and improve spraying efficiency. Fig. 9 As shown in ②, when the third electric push rod 1019 is controlled to extend forward, the side spray rod frame 1013 in the contracted state can be changed to the extended state, or when the third electric push rod 1019 is controlled to contract, the side spray rod frame 1013 in the extended state can be changed to the contracted state. Fig. 9 As shown in ①, in the extended state, when the end of the third electric push rod 1019 is controlled to continue to move outward, the push-pull shaft 1023 will be constrained by the inclined guide rod 1025, so that the push-pull shaft 1023 slides downward along the inclined surface of the inclined guide rod 1025 and enters the inclined groove. At the same time, under the support of the flip support shaft 1029, the lower slide rod 1022 is forced to flip upward. Finally, the push-pull shaft 1023 will fall into the bottom position 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 rod frame 1013 from transitioning to the inside and flipping.

[0044] When the flip support shaft 1029 flips upward, the entire side spray rod frame 1013 rotates along the axis of the push-pull shaft 1023, causing the upper slide bar 1033 to flip upward as well. When the upper slide bar 1033 flips, it slides along the through hole of the flip block 1037. At the same time, the flipped upper slide bar 1033 pushes the flip block 1037 to move inward, thereby compressing the spring 1039 through the side sliding column 1036. Finally, the flip block 1037 elastically presses against the outer side of the upper slide bar 1033. Fig. 9 In the figure, d1, d2 and d3 respectively represent the lengths of different installed lower springs 1039. The design of the flip block, spring and flip support shaft ensures the stability and reliability of the spray system during the flipping process. The flip block flips freely and is supported by the elasticity of the spring to ensure the smooth movement of the upper slide bar, avoiding excessive flipping or operating errors and improving the operational safety of the system.

[0045] This spray system can not only avoid over-application and reduce the waste of pesticides, but also improve the uniformity and accuracy of spraying, ensure the precise application of pesticides or fertilizers, and improve the overall benefits of agricultural production. The system realizes the flipping and adjustment functions through the cooperation of multiple structural components, with simple design and intuitive operation. The design of inclined grooves and limit rods effectively guides the movement of the spray rack, reduces complex operation steps, reduces the possibility of failure, and facilitates daily maintenance and operation. Through the flexible adjustment of multiple spraying modes, it can accurately cover the required area of ​​crops, improve the spraying effect and efficiency, reduce the waste of spraying pesticides or fertilizers, and save the cost of pesticide use.

[0046] Based on the above scheme, the use process of the spray system with a vertical flip function added to the side spray rod rack is as follows. First, ensure that all components of the spray rack are installed intact, especially key components such as electric push rods, push-pull shafts, springs, and flip blocks. Check whether the liquid path is unobstructed and whether the spray pipe is firmly connected. After the system is ready, the spray rack is in good working condition to ensure that the spraying operation can proceed smoothly. Then, according to the growth stage of the crop and the area to be sprayed, the controller is used to adjust the extension and contraction of the third electric push rod 1019, and the side spray rod rack 1013 is adjusted to an extended or contracted 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 excessive spraying or omissions, and improve the spraying efficiency. When the crop, such as corn, is high, or needs to be sprayed from the side, the third electric push rod 1019 is started to control the side spray rod rack to flip in the vertical direction. Guided by the push-pull shaft 1023 and the oblique guide rod 1025, the side spray rod rack flips to a suitable position along the flip support shaft 1029. During the turning process, the spray rack can be adjusted to an upright position (such as Fig. 9 As shown in ① in the figure), the spray pipe can be sprayed from the side to meet the spraying needs of high crops such as corn, ensuring the uniformity and coverage of the spraying. By operating accessories such as the flip block 1037 and the spring 1039, the spraying angle can be further adjusted so that the spray pipe 105 can be accurately aimed at the crop to avoid waste. If more precise spraying is required, the spray width and spraying angle can be further adjusted according to the crop height and growth conditions. After completing the spraying task, the controller is used to retract the third electric push rod 1019 so that the side spray rod frame returns to its original horizontal state from the upright state. At this time, the push-pull shaft 1023, driven by the oblique guide rod 1025, re-enters the lower track groove 1021, and the side spray rod frame returns to its initial state. The system returns to the retracted state, which is convenient for the storage or transfer of the equipment to the next spraying area, reducing the occupied space and ensuring the safety of the equipment.
