Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a combined fertilization and pesticide application machine for peach orchards. Background Technology

[0002] In the process of large-scale peach orchard planting, fertilization and pesticide application are key agricultural operations to ensure the growth of peach trees and improve fruit yield and quality. At present, fertilization and pesticide application operations in peach orchards mostly rely on single-function equipment or simple composite operation machines, which have many technical pain points and cannot meet the needs of precision operation.

[0003] The application process has several problems: First, the application pressure is difficult to control consistently. When the spray pipe is extended or the number of nozzles is adjusted, the pressure may drop, resulting in insufficient spray distance and failure to cover the upper canopy, or excessive pressure may damage the leaves. Second, the application is poorly adaptable. The fixed angle of the spray pipe makes it impossible to adjust flexibly according to the different tree heights (such as young trees and mature trees) and canopy widths of peach trees, leading to missed spraying inside the canopy and at the top, resulting in incomplete pest and disease control. Third, the application flow rate is out of sync with the speed of the application machine. When the speed is increased, insufficient flow rate may lead to incomplete application, while when the speed is decreased, excessive flow rate may cause pesticide waste and increase the risk of environmental pollution.

Detailed Implementation

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1 Reference Figures 1-5 , Figure 7 and Figures 9-11 This is the first embodiment of the present invention, which provides a combined fertilization and pesticide application machine for peach orchards. The machine includes a fertilization component 1 and a body 11, which moves forward via a trailer. The body 11 is equipped with wheels 12 rotatably connected to the body 11. Each wheel 12 has a blade that inserts into the soil when it travels on the ground, preventing slippage. A transmission mechanism 13 is located on one side of each wheel 12, connecting it to the wheel 12. The transmission mechanism 13 is a gear and chain structure. A fertilizer bin 14 is fixed to the body 11 for storing fertilizer. The fertilizer bin 14 is rotatably connected to the machine. The machine is equipped with an auger 15, which is powered by a transmission mechanism 13. When the walking wheel 12 rotates, it drives the auger 15 to rotate. A discharge pipe 16 is provided below the fertilizer box 14 and is connected to the fertilizer box 14. When the auger 15 rotates, fertilizer can fall from the discharge pipe 16. A trenching disc 17 is provided on the machine body 11, and a power box 18 is fixed on the machine body 11. The power box 18 is powered by the trenching disc 17 and can drive the trenching disc 17 to rotate, thereby making the trenching disc 17 dig trenches on the ground. The discharge pipe 16 moves in the trenches, thereby spreading fertilizer in the trenches. A soil covering disc is also provided on the machine body 11. After the fertilizer is spread by the discharge pipe 16, the soil covering disc can cover the fertilizer with soil.

[0039] The pesticide application component 2, mounted on the fertilizer application component 1, includes a sprayer 21 mounted on the body 11. The sprayer 21 includes a pesticide tank 211 fixed to the top of the body 11 for storing pesticides. A water pump 212 is fixed to one side of the fertilizer tank 14, with its inlet connected to the pesticide tank 211. A support platform 213 is fixed to the top of the body 11, and a support base 214 is fixed to the top of the support platform 213. A rotating pipe 215 is rotatably connected inside the support base 214. A connecting pipe 216 is fixed to the output end of the water pump 212, and the rotating pipe 215 is rotatably connected to... The surface of the connecting pipe 216 and the connection point between the rotating pipe 215 and the connecting pipe 216 are sealed. A connecting seat 217 is fixed to the surface of the rotating pipe 215. There are two connecting seats 217. A spray pipe 218 is fixed inside the connecting seat 217. Multiple spray nozzles 219 are fixed to the spray pipe 218 and are connected to the spray pipe 218. An adjusting pipe 2110 is rotatably connected inside the connecting seat 217. The surface of the adjusting pipe 2110 is in close contact with the inner wall of the spray pipe 218, sealing the connection point between the spray pipe 218 and the spray nozzles 219. The surface is provided with through grooves 2110-1, and there are three sets of through grooves 2110-1, four in a set. The shape of each set of through grooves 2110-1 is different. When the through grooves 2110-1 move to the connection between the spray pipe 218 and the nozzle 219, the agent in the regulating pipe 2110 can enter the nozzle 219 and be sprayed out. A pressure sensor 2111 is provided at the end of the spray pipe 218. The pressure sensor 2111 can detect the liquid pressure inside the spray pipe 218 and the regulating pipe 2110. When the liquid pressure detected by the pressure sensor 2111 is less than a threshold, the water pump... The increased rotation speed of pump 212 allows more pesticide to enter the spray pipe 218 and regulating pipe 2110, thereby increasing the liquid pressure. When the liquid pressure detected by pressure sensor 2111 exceeds the threshold, the rotation speed of pump 212 decreases, slowing down the rate at which pesticide enters the spray pipe 218 and regulating pipe 2110, thus reducing the liquid pressure. This ensures that the liquid pressure in the spray pipe 218 and regulating pipe 2110 remains within a certain range, thereby ensuring that the pesticide sprayed by nozzle 219 is within a certain range, preventing situations where the pesticide cannot reach the fruit trees or where the spraying force is too great.

[0040] Adjusting the speed of water pump 212 by detecting the liquid pressure through pressure sensor 2111 is existing technology, and those skilled in the art should be clear about its working principle, so it will not be described in detail here.

[0041] The nozzles 219 on the spray pipe 218 are also divided into three groups according to the distribution of the through grooves 2110-1, with four nozzles in each group. By rotating the regulating pipe 2110, one through groove 2110-1 in each group can be moved to the side of one nozzle 219 in each group, so that the agent in the regulating pipe 2110 enters the nozzle 219 and the nozzle 219 can spray the agent. As the regulating pipe 2110 continues to rotate, the second through groove 2110-1 in each group can be moved to the side of the second nozzle 219 in each group, so that the second nozzle 219 in that group sprays the agent. By continuing to rotate the regulating pipe 2110, the third and fourth nozzles 219 in each group can spray the agent in sequence, thereby ensuring that the nozzles 219 on the spray pipe 218 work evenly and that the spraying of the agent is uniform.

[0042] The number of groups of nozzles 219 and through channels 2110-1, as well as the division of the quantity within each group, is one implementation method of this embodiment. Those skilled in the art can make their own divisions as needed.

[0043] When the number of spray nozzles 219 that can spray pesticides changes, if the pressure of the liquid in the spray pipe 218 and the regulating pipe 2110 cannot be regulated, that is, if the water pump 212 keeps its speed constant, that is, if the flow rate of pesticides entering the spray pipe 218 and the regulating pipe 2110 remains constant, when there are many working nozzles 219, the spraying stroke of the nozzles 219 becomes shorter, and the leaves of the fruit trees will not be sprayed. When there are few working nozzles 219, the pressure of the spraying pesticides increases, which will lead to excessive spraying force, thereby damaging the leaves of the fruit trees.

[0044] When the fertilizer and pesticide application machine moves at a certain speed, the nozzle 219 can spray pesticides on the fruit trees on one side. When the moving speed of the fertilizer and pesticide application machine decreases, the regulating pipe 2110 is rotated to reduce the number of working nozzles 219, that is, to reduce the real-time spraying amount of pesticides. This prevents the fertilizer and pesticide application machine from staying next to the same fruit tree for too long, which could lead to excessive pesticide spraying. When the moving speed of the fertilizer and pesticide application machine increases, the regulating pipe 2110 is rotated in the opposite direction, allowing more nozzles 219 to work, thereby increasing the real-time spraying amount of pesticides and ensuring that the fruit trees are sprayed with enough pesticides while the machine is moving quickly.

[0045] Example 2 Reference Figures 3-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0046] Specifically, the application assembly 2 also includes a swinging component 22 disposed on the rotating tube 215. The swinging component 22 includes a swing rod 221 rotatably connected to the surface of the rotating tube 215. The surface of the rotating tube 215 is provided with positioning grooves 215-1. There are multiple positioning grooves 215-1, which are distributed circumferentially on the surface of the rotating tube 215. The surface of the swing rod 221 is rotatably connected to a fixing bolt 222 by a thread. The end of the fixing bolt 222 is located in the positioning groove 215-1.

[0047] By pressing the end of the fixing bolt 222 against the positioning groove 215-1, the swing rod 221 and the rotating tube 215 are fixed together, so that the swing rod 221 can drive the rotating tube 215 to rotate. By inserting the end of the fixing bolt 222 into different positioning grooves 215-1, the spray pipe 218 can be in different tilt angles in the initial state.

[0048] When the spray pipe 218 swings under the drive of the rotating pipe 215, the spraying range of the spray pipe 218 can be increased. By adjusting the initial tilt angle of the spray pipe 218, it can be adapted to fruit trees of different heights and canopies.

[0049] Specifically, the swing component 22 also includes a pulley 223 fixed to the surface of the auger 15, a rotating seat 224 fixed to the top of the support platform 213, a rotating shaft 225 rotatably connected inside the rotating seat 224, and a pulley 223 fixed to the surface of the rotating shaft 225. The two pulleys 223 are connected by a belt.

[0050] When the auger 15 rotates, it can drive the rotating shaft 225 to rotate through the belt pulley 223. Since the auger 15 rotates synchronously with the traveling wheel 12, when the traveling wheel 12 stops moving, that is, when the machine stops in place, the auger 15 stops rotating, and at this time the rotating shaft 225 stops rotating.

[0051] Specifically, the swing component 22 also includes a rotating disk 2212 fixed to the end of the rotating shaft 225. A drive column 226 is fixed on one side of the rotating disk 2212, and a guide column 227 is fixed on the top of the support platform 213. A lifting frame 228 slides on the surface of the guide column 227. The setting of the guide column 227 can ensure the stable lifting of the lifting frame 228. An extrusion groove 228-1 is opened on the surface of the lifting frame 228, and the drive column 226 slides in the extrusion groove 228-1.

[0052] When the rotating shaft 225 rotates, it can drive the rotating disk 2212 to rotate, thereby causing the rotating disk 2212 to drive the drive column 226 to squeeze the extrusion groove 228-1, thereby causing the lifting frame 228 to move back and forth. In the figure, the lifting frame 228 is at the lowest point of its stroke.

[0053] Specifically, the swing component 22 also includes a connecting seat 229 rotatably connected to the lifting frame 228. A compression pipe 2210 is fixed on one side of the connecting seat 229. The compression pipe 2210 slides on the surface of the swing rod 221. The connection between the swing rod 221 and the compression pipe 2210 is sealed to prevent gas leakage. A one-way valve 2211 is fixed at the end of the compression pipe 2210. A one-way valve 2211 is also fixed inside the swing rod 221.

[0054] When the lifting frame 228 rises from the current illustrated state, the compression pipe 2210 can be moved by the connecting seat 229, so that the compression pipe 2210 moves away from the swing arm 221 and causes the swing arm 221 to swing. When the lifting frame 228 falls from the highest point, the compression pipe 2210 will move closer to the swing arm 221 again, thereby compressing the air between the swing arm 221 and the compression pipe 2210.

[0055] The one-way valve 2211 allows external gas to enter the compression pipe 2210 and then be compressed by the compression pipe 2210 into the rocker arm 221.

[0056] Example 3 Reference Figures 1-17 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0057] Specifically, the application component 2 also includes an adjustment component 23 disposed on the connecting seat 217. The adjustment component 23 includes a connecting rod 231 fixed to the surface of the adjustment tube 2110. A toothed ring 232 is fixed to the end of the connecting rod 231. A moving groove 217-1 is opened on the surface of the connecting seat 217, and the connecting rod 231 slides in the moving groove 217-1.

[0058] When the gear ring 232 rotates, it can drive the connecting rod 231 to move and drive the regulating tube 2110 to rotate. Since the regulating tube 2110 is rotatably connected to the connecting seat 217, and the connection between the connecting seat 217 and the regulating tube 2110 is sealed, the agent in the connecting seat 217 will not leak from the moving groove 217-1.

[0059] Specifically, the adjusting component 23 also includes a limiting shell 233 fixed on the connecting seat 217, a movable frame 234 sliding inside the limiting shell 233, a rack 235 fixed on one side of the movable frame 234, and the rack 235 meshing with the toothed ring 232.

[0060] When the moving frame 234 moves the rack 235, the rack 235 can drive the toothed ring 232 to rotate, which in turn drives the adjusting tube 2110 to rotate, thereby adjusting the number of working nozzles 219.

[0061] Specifically, the application assembly 2 also includes a power component 24 mounted on the connecting seat 217. The power component 24 includes a support plate 241 fixed to one side of the connecting seat 217, a guide tube 242 fixed on the support plate 241, and a fixed seat 243 fixed inside the guide tube 242. The fixed seat 243 is connected to the swing rod 221 through a conduit, allowing compressed gas inside the swing rod 221 to enter the fixed seat 243. A telescopic tube 2415 is fixed to one side of the fixed seat 243, and the telescopic tube 2415 can extend and retract. A movable seat 244 is fixed to the other side of the telescopic tube 2415. The movable seat 244, the telescopic tube 2415, and the fixed seat 243 together form a retractable storage tank structure. The surface of the movable seat 244... A slider 245 is fixed and slides inside the guide tube 242, preventing the movable seat 244 from rotating inside the guide tube 242. A pull rod 246 is fixed inside the movable frame 234, with the other end of the pull rod 246 fixed to the inner wall of the movable seat 244. The pull rod 246 slides inside the fixed seat 243. The connection between the pull rod 246 and the fixed seat 243 is sealed to prevent gas leakage. A first spring 247 is fixed to the inner wall of the fixed seat 243. The first spring 247 is currently in a stretched state, and the other end of the first spring 247 is fixed to the inner wall of the movable seat 244. A vent hole 244-1 is provided on the surface of the movable seat 244 to discharge compressed gas inside the movable seat 244.

[0062] As the machine's travel speed increases, the rotation speed of the rotating disc 2212 also increases, causing the reciprocating lifting frequency of the lifting frame 228 to increase. This means that the compression pipe 2210 can compress more air into the swing arm 221 in the same amount of time. If the gas flow rate from the swing arm 221 to the fixed seat 243 through the guide tube is greater than the discharge flow rate of the vent hole 244-1, the increase in gas will cause the telescopic pipe 2415 to extend, thereby causing the moving seat 244 to pull the pull rod 246. At this time, the pull rod 246 can drive the rack 235 to move through the moving frame 234, thereby causing the rack 235 to drive the regulating pipe 2110 to rotate through the gear ring 232. This allows more nozzles 219 to enter the working state, increasing the overall spraying flow rate of the nozzles 219, thus ensuring that there is still enough pesticide to spray onto the fruit trees when the machine is traveling at high speed.

[0063] Similarly, when the machine travels at a slower speed, the gas flow rate entering the fixed seat 243 is less than the discharge flow rate of the vent 244-1. Under the pull of the first spring 247, the movable seat 244 can be reset, thereby driving the pull rod 246 to reset, causing the regulating pipe 2110 to rotate in the opposite direction, thereby closing most of the nozzles 219, reducing the overall spray flow rate of the nozzles 219, and preventing excessive pesticides from being sprayed onto the fruit trees when the machine is traveling slowly.

[0064] Specifically, the power component 24 also includes a guide ring 248 fixed to the inner wall of the movable seat 244. There are two guide rings 248, which are nested inside each other. A rotating sleeve 249 is rotatably connected to the surface of the pull rod 246. A drive housing 2410 is fixed to the surface of the rotating sleeve 249. The drive housing 2410 slides between the two guide rings 248. A sealing plate 2411 slides inside the drive housing 2410. A second spring 2412 is fixed to the inner wall of the sealing plate 2411. The other end of the second spring 2412 is fixed to the inner wall of the drive housing 2410. The second spring 2412 is in a compressed state and is used to push the sealing plate 2411 so that the sealing plate 2411 can be pressed against one side of the vent hole 244-1, thereby sealing the vent hole 244-1.

[0065] By rotating the rotating sleeve 249, the rotating sleeve 249 can drive the drive housing 2410 to move, thereby causing the drive housing 2410 to drive the sealing plate 2411 to slide on one side of the vent hole 244-1, thereby adjusting the area of ​​the vent hole 244-1 sealed by the sealing plate 2411, and thus adjusting the flow rate of the gas discharged from the vent hole 244-1.

[0066] Specifically, a drive sleeve 2413 is fixed on the surface of the fixed base 243, and a rotating sleeve 249 slides inside the drive sleeve 2413. A drive thread groove 2413-1 is opened inside the drive sleeve 2413, and a drive block 2414 is fixed on the surface of the rotating sleeve 249. The drive block 2414 slides inside the drive thread groove 2413-1.

[0067] When the moving speed of the machine increases, the gas flow rate entering the fixed seat 243 increases. This causes the moving seat 244 to move away from the fixed seat 243, which can drive the drive block 2414 to slide in the drive thread groove 2413-1. This causes the rotating sleeve 249 to rotate, thereby reducing the area sealed by the sealing plate 2411 of the vent hole 244-1 and increasing the venting capacity of the vent hole 244-1. When the discharge flow rate of the vent hole 244-1 is equal to the gas flow rate entering the fixed seat 243, the moving seat 244 stops moving. If the moving speed of the machine increases or decreases at this time, the gas flow rate entering the fixed seat 243 will change, causing the moving seat 244 to move again. This will drive the pull rod 246 to move, thereby adjusting the angle of the regulating pipe 2110 and thus adjusting the overall spray flow rate of the nozzle 219.

[0068] In summary, the present invention has the following beneficial effects: 1. To ensure stable application pressure and prevent pesticide spraying failure or damage to fruit trees, a pressure sensor 2111 is installed at the end of the spray pipe 218 to monitor the liquid pressure inside the spray pipe 218 and regulating pipe 2110 in real time, and to control the speed of the water pump 212 in conjunction with the pressure: when the pressure is lower than the threshold, the speed of the water pump 212 is increased to increase the pesticide input, preventing the nozzle 219 from failing to spray the pesticide on the fruit trees due to insufficient pressure; when the pressure is higher than the threshold, the speed of the water pump 212 is reduced to reduce the pesticide input, preventing excessive pressure from damaging the leaves of the fruit trees. This design ensures that the nozzle 219 always sprays at an appropriate pressure, which not only ensures the pesticide application effect but also protects the fruit trees from damage.

[0069] Second, improve the adaptability and coverage of pesticide application to suit different tree conditions. On the one hand, by using the cooperation between the fixing bolt 222 in the swinging component 22 and the different positioning grooves 215-1 on the surface of the rotating pipe 215, the initial tilt angle of the spray pipe 218 can be adjusted to suit fruit trees of different heights, such as young trees and mature trees. On the other hand, by using the auger 15 to drive the belt pulley 223 to drive the rotating shaft 225 to drive the rotating disk 2212 to rotate, and by using the drive column 226 to squeeze the squeezing groove 228-1 of the lifting frame 228, the compression pipe 2210 and the swing arm 221 swing back and forth, thereby allowing the spray pipe 218 to dynamically adjust the spraying angle, expand the coverage of the fruit tree canopy, and avoid missed spraying inside the canopy or at the top.

[0070] 3. The system achieves linkage between pesticide application rate and operating speed, precisely controlling pesticide dosage. When the machine's speed changes, the system automatically adjusts the pesticide application rate: When the machine's speed increases, the traveling wheels 12 drive the auger 15 to rotate faster, compressing more air into the swing arm 221 via the compression pipe 2210. The gas enters the fixed seat 243 and pushes the telescopic pipe 2415 to extend. The moving seat 244, through the pull rod 246, drives the moving frame 234 and rack 235 to move, causing the gear ring 232 to drive the adjusting pipe 2110. Rotation increases the number of working nozzles 219 and improves the spray flow rate, ensuring that the fruit trees still receive sufficient pesticide even when moving quickly. When the machine speed decreases, the gas input decreases, the first spring 247 pulls the moving seat 244 to reset, and the regulating pipe 2110 rotates in the opposite direction to close some nozzles 219, reducing the flow rate and preventing excessive pesticide use at slow speeds. At the same time, the drive block 2414 slides in the drive threaded groove 2413-1 to adjust the exhaust volume of the vent hole 244-1, maintain a stable flow rate, and reduce pesticide waste.

[0071] When fertilizing or applying pesticides to fruit trees, the compound operation machine moves to one side of the fruit tree. At this time, the trenching plate 17 can open a trench, allowing the feeding pipe 16 to sprinkle fertilizer into the trench, and then the covering plate will cover the fertilizer.

[0072] If pesticides need to be applied while fertilizing, the water pump 212 can be started to transport the pesticides in the pesticide tank 211 to the spray pipe 218, and then spray them onto the fruit trees from the nozzle 219.

[0073] When the moving speed of the composite operation machine increases, the rotation speed of the traveling wheel 12 increases, which in turn increases the rotation speed of the rotating shaft 225. This increases the reciprocating lifting frequency of the lifting frame 228, and more air is compressed into the swing arm 221 per unit time, allowing more gas to enter the fixed seat 243. At this time, the flow rate of gas entering the fixed seat 243 is greater than the discharge flow rate of the vent hole 244-1, causing the telescopic tube 2415 to extend. This causes the moving seat 244 to pull the pull rod 246. The pull rod 246 can then drive the rack 235 to move through the moving frame 234, which in turn drives the regulating tube 2110 to rotate through the gear ring 232. This allows more nozzles 219 to enter the working state, increasing the overall spraying flow rate of the nozzles 219. This ensures that even when the operation machine is moving at high speed, there is still enough pesticide to spray onto the fruit trees.

[0074] As the movable seat 244 moves, it moves away from the fixed seat 243, which can drive the drive block 2414 to slide in the drive thread groove 2413-1, thereby causing the rotating sleeve 249 to rotate. This reduces the area of ​​the vent hole 244-1 sealed by the sealing plate 2411, increasing the venting capacity of the vent hole 244-1. When the discharge flow rate of the vent hole 244-1 is equal to the gas flow rate entering the fixed seat 243, the movable seat 244 stops moving, that is, the overall spray flow rate of the nozzle 219 remains stable.

[0075] If the moving speed of the machine increases or decreases at this time, the gas flow rate entering the fixed seat 243 will change, causing the moving seat 244 to move again in real time, thereby driving the pull rod 246 to move, thereby adjusting the angle of the regulating pipe 2110 in real time, thereby adjusting the overall real-time spraying flow rate of the nozzle 219, and preventing insufficient or excessive spraying of the agent.
