[0039] The medicine applying assembly 2 is arranged on the fertilizer applying assembly 1, and comprises a spraying part 21 arranged on the machine body 11, wherein the spraying part 21 comprises a medicine tank 211 fixed to the top of the machine body 11, the medicine tank 211 is used for storing medicine, one side of the fertilizer tank 14 is fixed with a water pump 212, the water inlet end of the water pump 212 is communicated with the medicine tank 211, the top of the machine body 11 is fixed with a supporting table 213, the top of the supporting table 213 is fixed with a supporting seat 214, the supporting seat 214 is rotatably connected with a rotating pipe 215, the output end of the water pump 212 is fixed with a connecting pipe 216, the rotating pipe 215 is rotatably connected to the surface of the connecting pipe 216, the connecting position of the rotating pipe 215 and the connecting pipe 216 is sealed, the surface of the rotating pipe 215 is fixed with a communicating seat 217, the number of the communicating seat 217 is two, the communicating seat 217 is fixed with a spraying pipe 218, the spraying pipe 218 is fixed with a spray head 219, the number of the spray head 219 is multiple, the spray head 219 is communicated with the spraying pipe 218, the communicating seat 217 is rotatably connected with an adjusting pipe 2110, the surface of the adjusting pipe 2110 is close to the inner wall of the spraying pipe 218, and the communicating position of the spraying pipe 218 and the spray head 219 can be sealed, the surface of the adjusting pipe 2110 is provided with a through groove 2110-1, the number of the through groove 2110-1 is three groups, four groups are a group, the shapes of the through grooves 2110-1 in each group are different, when the through groove 2110-1 moves to the communicating position of the spraying pipe 218 and the spray head 219, the medicine in the adjusting pipe 2110 can enter the spray head 219 and then be sprayed out, the end of the spraying pipe 218 is provided with a pressure sensor 2111, the pressure sensor 2111 can detect the liquid pressure in the spraying pipe 218 and the adjusting pipe 2110, when the liquid pressure detected by the pressure sensor 2111 is less than a threshold value, the rotating speed of the water pump 212 is increased, so that more medicine enters the spraying pipe 218 and the adjusting pipe 2110, thereby increasing the liquid pressure, when the liquid pressure detected by the pressure sensor 2111 is greater than the threshold value, the rotating speed of the water pump 212 is reduced, so that the speed of the medicine entering the spraying pipe 218 and the adjusting pipe 2110 is slowed down, thereby reducing the liquid pressure, so as to ensure that the liquid pressure in the spraying pipe 218 and the adjusting pipe 2110 is within a certain range, thereby ensuring that the medicine sprayed out of the spray head 219 is within a certain range, and avoiding the cases that the medicine cannot be sprayed to the fruit trees or the spraying force is too large.

[0040] The rotating speed of the water pump 212 adjusted by the liquid pressure detected by the pressure sensor 2111 is prior art, and the working principle thereof is clear to those skilled in the art, which will not be described here.

[0041] The spray heads 219 on the spray pipe 218 are divided into three groups, each group having four spray heads 219 according to the distribution of the through slots 2110-1. By rotating the adjusting pipe 2110, one through slot 2110-1 in each group of through slots 2110-1 is moved to one side of one spray head 219 in each group of spray heads 219, so that the medicament in the adjusting pipe 2110 enters the spray head 219, and the spray head 219 can spray the medicament. As the adjusting pipe 2110 continues to rotate, a second through slot 2110-1 in each group of through slots 2110-1 is moved to one side of a second spray head 219 in each group of spray heads 219, so that the second spray head 219 in the group sprays the medicament. As the adjusting pipe 2110 continues to rotate, a third and a fourth spray head 219 in each group of spray heads 219 can spray the medicament in turn, so as to ensure that the spray heads 219 on the spray pipe 218 work uniformly and ensure the uniformity of the sprayed medicament.

[0042] The number of groups of spray heads 219 and the number of spray heads 219 in each group are divided as an embodiment of the present embodiment, and those skilled in the art can divide them according to the needs.

[0043] When the number of spray heads 219 that can spray the medicament changes, if the pressure of the liquid in the spray pipe 218 and the adjusting pipe 2110 cannot be adjusted, that is, the flow rate of the medicament entering the spray pipe 218 and the adjusting pipe 2110 remains unchanged, when the number of working spray heads 219 is large, the stroke of the spray head 219 spraying the medicament is short, and the leaves of the fruit trees cannot be sprayed. When the number of working spray heads 219 is small, the pressure of the spray head 219 spraying the medicament increases, which can cause the spraying force to be too large, thereby causing damage to the leaves of the fruit trees.

[0044] When the fertilizing and medicating combined working machine moves at a certain speed, the spray heads 219 can spray the medicament to the fruit trees on one side. When the moving speed of the fertilizing and medicating combined working machine decreases, the adjusting pipe 2110 is rotated to reduce the number of working spray heads 219, that is, to reduce the real-time spraying amount of the medicament, thereby preventing the fertilizing and medicating combined working machine from staying beside the same fruit tree for too long, which can cause the medicament to be sprayed too much. When the moving speed of the fertilizing and medicating combined working machine increases, the adjusting pipe 2110 is rotated in the opposite direction, so that more spray heads 219 can work, thereby increasing the real-time spraying amount of the medicament, and ensuring that the fruit trees are sprayed with enough medicament while the working machine moves quickly.

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

[0046] Specifically, the medicine applying assembly 2 further comprises a swing member 22 arranged on the rotating pipe 215, the swing member 22 comprises a swing rod 221 rotatably connected to the surface of the rotating pipe 215, the surface of the rotating pipe 215 is provided with a plurality of positioning grooves 215-1 which are circumferentially distributed on the surface of the rotating pipe 215, and the surface of the swing rod 221 is threadedly rotatably connected with a fixing bolt 222, and the end of the fixing bolt 222 is located in the positioning groove 215-1.

[0047] The end of the fixing bolt 222 extrudes the positioning groove 215-1, so that the swing rod 221 and the rotating pipe 215 are fixed together, so that the swing rod 221 can drive the rotating pipe 215 to rotate, and by inserting the end of the fixing bolt 222 into different positioning grooves 215-1, the spraying pipe 218 can be at different inclination angles in the initial state.

[0048] When the spraying pipe 218 swings under the driving of the rotating pipe 215, the spraying range of the spraying pipe 218 can be increased, and by adjusting the initial inclination angle of the spraying pipe 218, different height and crown of the fruit trees can be adapted.

[0049] Specifically, the swing member 22 further comprises a belt pulley 223 fixed to the surface of the auger 15, the top of the support table 213 is fixed with a rotating seat 224, the rotating seat 224 is rotatably connected with a rotating shaft 225, the surface of the rotating shaft 225 is also fixed with a belt pulley 223, and the two belt pulleys 223 are connected through a belt.

[0050] When the auger 15 rotates, the rotating shaft 225 can be driven to rotate through the belt pulley 223, and since the auger 15 rotates synchronously with the walking wheel 12, when the walking wheel 12 is stationary, i.e. the working machine is stopped at the original position, the auger 15 stops rotating, and at this time, the rotating shaft 225 stops rotating.

[0051] Specifically, the swing member 22 further comprises a rotating disc 2212 fixed to the end of the rotating shaft 225, the rotating disc 2212 is fixed with a driving column 226 on one side, the top of the support table 213 is fixed with a guide column 227, the surface of the guide column 227 is slidably provided with a lifting frame 228, and the guide column 227 is arranged to ensure stable lifting of the lifting frame 228, the surface of the lifting frame 228 is provided with an extrusion groove 228-1, and the driving column 226 slides in the extrusion groove 228-1.

[0052] When the rotating shaft 225 rotates, the rotating disc 2212 can be driven to rotate, so that the rotating disc 2212 drives the driving column 226 to extrude the extrusion groove 228-1, so that the lifting frame 228 moves up and down reciprocatingly, and in the figure, the lifting frame 228 is at the lowest point of its stroke.

[0053] Specifically, the swing member 22 further comprises a connecting seat 229 rotatably connected to the lifting frame 228, one side of the connecting seat 229 is fixedly connected with a compression pipe 2210, the compression pipe 2210 slides on the surface of a swing rod 221, the connecting position of the swing rod 221 and the compression pipe 2210 is sealed to prevent gas leakage at the connecting position, and the end of the compression pipe 2210 is fixedly connected with a one-way valve 2211, and the swing rod 221 is also fixedly connected with the one-way valve 2211.

[0054] When the lifting frame 228 rises from the current state shown in the figure, the compression pipe 2210 can be driven to move through the connecting seat 229, so that the compression pipe 2210 moves away from the swing rod 221 while driving the swing rod 221 to swing, and when the lifting frame 228 falls from the highest point, the compression pipe 2210 will again approach the swing rod 221, so as to compress the air between the swing rod 221 and the compression pipe 2210.

[0055] The one-way valve 2211 is arranged, so that the gas outside can only enter the compression pipe 2210, and then the gas is compressed into the swing rod 221 by the compression pipe 2210.

[0056] Embodiment 3 Referring to Figures 1-17 This embodiment is based on the previous two embodiments.

[0057] Specifically, the medicine applying assembly 2 further comprises an adjusting member 23 arranged on the communicating seat 217, the adjusting member 23 comprises a connecting rod 231 fixedly connected to the surface of an adjusting pipe 2110, the end of the connecting rod 231 is fixedly connected with a tooth ring 232, the surface of the communicating seat 217 is provided with a moving groove 217-1, and the connecting rod 231 slides in the moving groove 217-1.

[0058] When the tooth ring 232 rotates, the connecting rod 231 can be driven to move, and the adjusting pipe 2110 can be driven to rotate, because the adjusting pipe 2110 is rotatably connected to the communicating seat 217, and the connecting position of the communicating seat 217 and the adjusting pipe 2110 is sealed, the medicine in the communicating seat 217 will not leak from the moving groove 217-1.

[0059] Specifically, the adjusting member 23 further comprises a limiting shell 233 fixedly connected to the communicating seat 217, a moving frame 234 slides in the limiting shell 233, one side of the moving frame 234 is fixedly connected with a gear rack 235, and the gear rack 235 is engaged with the tooth ring 232.

[0060] When the moving frame 234 drives the gear rack 235 to move, the gear rack 235 can drive the tooth ring 232 to rotate, so that the tooth ring 232 drives the adjusting pipe 2110 to rotate, and the number of working nozzles 219 can be adjusted in this way.

[0061] Specifically, the medicine applying assembly 2 further comprises a power component 24 arranged on the communication seat 217. The power component 24 comprises a support plate 241 fixed to one side of the communication seat 217. A guide pipe 242 is fixed to the support plate 241. A fixing seat 243 is fixed in the guide pipe 242. The fixing seat 243 is communicated with the guide pipe and the swing rod 221, so that the compressed gas in the swing rod 221 can enter the fixing seat 243. An extension pipe 2415 is fixed to one side of the fixing seat 243. The extension pipe 2415 can be telescopically moved. A moving seat 244 is fixed to the other side of the extension pipe 2415. The moving seat 244, the extension pipe 2415 and the fixing seat 243 jointly form a telescopic storage tank structure. A sliding block 245 is fixed to the surface of the moving seat 244. The sliding block 245 slides in the guide pipe 242, so that the moving seat 244 cannot rotate in the guide pipe 242. A pull rod 246 is fixed in the moving frame 234. The other end of the pull rod 246 is fixed to the inner wall of the moving seat 244. The pull rod 246 slides in the fixing seat 243. The joint between the pull rod 246 and the fixing seat 243 is sealed, so as to prevent gas leakage. A first spring 247 is fixed to the inner wall of the fixing seat 243. The first spring 247 is in a stretched state at present. The other end of the first spring 247 is fixed to the inner wall of the moving seat 244. A gas discharge hole 244-1 is arranged on the surface of the moving seat 244. The gas discharge hole 244-1 can discharge the compressed gas in the moving seat 244.

[0062] When the running speed of the working machine increases, the rotating speed of the rotating disc 2212 increases, so that the reciprocating lifting frequency of the lifting frame 228 increases, that is, the compressed pipe 2210 can compress more air into the swing rod 221 in the same time. At this time, if the gas flow of the swing rod 221 entering the fixing seat 243 through the guide pipe is greater than the discharge flow of the gas discharge hole 244-1, the extension pipe 2415 is elongated with the increase of the gas, so that the moving seat 244 pulls the pull rod 246. At this time, the pull rod 246 can drive the rack 235 to move through the moving frame 234, so that the rack 235 drives the adjusting pipe 2110 to rotate through the gear ring 232, so as to make more nozzles 219 enter the working state, improve the overall spraying flow of the nozzles 219, and ensure that the working machine can still have enough pesticide sprayed on the fruit trees when running fast.

[0063] Similarly, when the running speed of the working machine decreases, the gas flow entering the fixing seat 243 is less than the discharge flow of the gas discharge hole 244-1 at this time. Under the pulling of the first spring 247, the moving seat 244 can be reset, so as to reset the pull rod 246, so as to reversely rotate the adjusting pipe 2110, so as to close most of the nozzles 219, reduce the overall spraying flow of the nozzles 219, and avoid that too much pesticide is sprayed on the fruit trees when the working machine runs slowly.

[0064] Specifically, the power component 24 further comprises a guide ring 248 fixed to the inner wall of the moving seat 244, the number of the guide rings 248 is two, the guide rings 248 are arranged in a nested manner, the surface of the pull rod 246 is rotationally connected with a rotating sleeve 249, the surface of the rotating sleeve 249 is fixed with a driving shell 2410, the driving shell 2410 slides between the two guide rings 248, the driving shell 2410 internally slides with a sealing plate 2411, the inner wall of the sealing plate 2411 is fixed with a second spring 2412, the other end of the second spring 2412 is fixed to the inner wall of the driving shell 2410, the second spring 2412 is in a compressed state, used for pushing the sealing plate 2411, so that the sealing plate 2411 can be extruded on one side of the air vent hole 244-1, thereby the air vent hole 244-1 can be sealed.

[0065] By rotating the rotating sleeve 249, the rotating sleeve 249 drives the driving shell 2410 to move, so that the driving shell 2410 drives the sealing plate 2411 to slide on one side of the air vent hole 244-1, thereby adjusting the area of the air vent hole 244-1 sealed by the sealing plate 2411, so as to adjust the flow of the air vent hole 244-1.

[0066] Specifically, the surface of the fixed seat 243 is fixed with a driving sleeve 2413, the rotating sleeve 249 slides in the driving sleeve 2413, the driving sleeve 2413 is internally provided with a driving thread groove 2413-1, the surface of the rotating sleeve 249 is fixed with a driving block 2414, the driving block 2414 slides in the driving thread groove 2413-1.

[0067] When the moving speed of the working machine increases, the flow of the gas entering the fixed seat 243 increases, at this time, the moving seat 244 moves away from the fixed seat 243, which drives the driving block 2414 to slide in the driving thread groove 2413-1, so that the rotating sleeve 249 rotates, thereby reducing the area of the air vent hole 244-1 sealed by the sealing plate 2411, and increasing the exhaust capacity of the air vent hole 244-1, when the flow of the air vent hole 244-1 and the flow of the gas entering the fixed seat 243 are equal, the moving seat 244 stops moving, at this time, if the moving speed of the working machine increases or decreases, the flow of the gas entering the fixed seat 243 changes, so that the moving seat 244 moves again in real time, thereby driving the pull rod 246 to move, so as to adjust the angle of the adjusting pipe 2110, thereby adjusting the overall spraying flow of the nozzle 219.

[0068] In summary, the present application has the following beneficial effects: One, ensure stable spraying pressure, avoid ineffective spraying or damage to fruit trees, by setting pressure sensor 2111 at the end of spray pipe 218, real-time monitoring of the liquid pressure inside spray pipe 218 and adjusting pipe 2110, and controlling the speed of water pump 212 in linkage: when the pressure is lower than the threshold, the speed of water pump 212 is increased to increase the input of pesticide, to prevent the nozzle 219 from not spraying the fruit trees due to insufficient pressure; when the pressure is higher than the threshold, the speed of water pump 212 is reduced to reduce the input of pesticide, to avoid damage to the leaves of fruit trees due to excessive pressure, this design ensures that the nozzle 219 always sprays at the appropriate pressure, which not only ensures the effect of pesticide application, but also protects the fruit trees from damage.

[0069] Two, improve the adaptability and coverage of pesticide application, adapt to different tree conditions, on the one hand, by using the cooperation of fixed bolt 222 in swing piece 22 and different positioning grooves 215-1 on the surface of rotating pipe 215, the initial inclination angle of spray pipe 218 can be adjusted to adapt to fruit trees of different heights such as young trees and adult trees; on the other hand, by driving the belt pulley 223 with the auger 15, the rotating shaft 225 drives the rotating disc 2212 to rotate, through the driving column 226 extruding the extrusion groove 228-1 of the lifting frame 228, the compression pipe 2210 and the swing rod 221 are reciprocally swung, and then the spray pipe 218 dynamically adjusts the spraying angle to expand the coverage of the tree canopy, avoiding missed spraying in the canopy or the top.

[0070] Three, realize the linkage of pesticide application flow and operation speed, accurately control the amount of pesticide, when the speed of the working machine changes, the system can automatically adjust the pesticide application flow: when the speed of the working machine increases, the rotating wheel 12 drives the auger 15 to increase the speed, the compression pipe 2210 compresses more air into the swing rod 221, the gas enters the fixed seat 243 to push the telescopic pipe 2415 to extend, the moving seat 244 moves the moving frame 234 and the rack 235 through the pull rod 246, so that the gear ring 232 drives the adjusting pipe 2110 to rotate, increasing the number of working nozzles 219 and the spraying flow, to ensure that the fruit trees can still obtain enough pesticide when moving fast; when the speed of the working machine decreases, the amount of gas input decreases, the first spring 247 pulls the moving seat 244 to reset, the adjusting pipe 2110 reversely rotates to close part of the nozzles 219, reducing the flow, to avoid excessive pesticide when moving slowly, at the same time, the driving block 2414 slides in the driving thread groove 2413-1, adjusting the exhaust amount of the air vent 244-1, to maintain stable flow and reduce waste of pesticide.

[0071] In use, when it is necessary to apply fertilizer and pesticide to fruit trees, the combined working machine is moved on one side of the fruit trees, at this time the furrowing disc 17 can open a trench, the fertilizer pipe 16 can sprinkle the fertilizer into the trench, and then the covering disc can bury the fertilizer.

[0072] When the fertilizer is applied, if the pesticide needs to be applied, the water pump 212 is started to deliver the pesticide in the pesticide tank 211 to the spraying pipe 218, and then sprayed to the fruit trees from the spray head 219.

[0073] When the moving speed of the combined machine is increased, the rotating speed of the walking wheel 12 is increased, so that the rotating speed of the rotating shaft 225 is increased, thereby increasing the reciprocating lifting frequency of the lifting frame 228, and more air is compressed into the swing rod 221 per unit time, so that more gas enters the fixed seat 243, and at this time, the flow of the gas entering the fixed seat 243 is greater than the discharge flow of the air vent 244-1, so that the telescopic pipe 2415 is elongated, thereby pulling 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, so that the rack 235 drives the adjusting pipe 2110 to rotate through the gear ring 232, so that more spray heads 219 enter the working state, and the overall spraying flow of the spray head 219 is increased, so as to ensure that the machine can still spray enough pesticide to the fruit trees when moving at a high speed.

[0074] When the moving seat 244 moves away from the fixed seat 243, the driving block 2414 can slide in the driving threaded groove 2413-1, so that the rotating sleeve 249 rotates, thereby reducing the area of the air vent 244-1 sealed by the sealing plate 2411, and increasing the exhaust capacity of the air vent 244-1. When the discharge flow of the air vent 244-1 and the flow of the gas entering the fixed seat 243 are equal, the moving seat 244 stops moving, that is, the overall spraying flow of the spray head 219 remains stable.

[0075] At this time, if the moving speed of the machine is increased or decreased, the flow of the gas entering the fixed seat 243 will change, thereby causing the moving seat 244 to move again in real time, thereby driving the pull rod 246 to move, so as to adjust the angle of the adjusting pipe 2110 in real time, thereby adjusting the real-time spraying flow of the spray head 219, to prevent insufficient or excessive spraying of the pesticide.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
