Description

Technical Field

[0001] This invention relates to the field of disease control technology, specifically to an application device and method for controlling plant root diseases. Background Technology

[0002] Root rot is a common disease encountered during plant cultivation. This disease is usually spread through the soil. If these diseases are not controlled in a timely and effective manner, plant growth will be affected, and the disease may even gradually worsen, affecting all plants in the entire plot.

[0003] Root rot is mainly caused by the combined effects of pathogen infection, environmental factors, and other factors.

[0004] The main pathogens include soil-borne fungi and bacteria, among which soil-borne fungi are the main pathogenic group, including Fusarium (which secretes toxins that damage the root system and cause browning of the vascular bundles), Rhizoctonia (which causes root and stem rot and is susceptible to seedlings), Pythium (which is prevalent in humid and cold environments and causes water-soaked rot of the roots), and Phytophthora (which causes black rot of the root and stem).

[0005] Environmental factors such as excessive soil moisture, long-term waterlogging, or poor drainage can cause root hypoxia, leading to decreased resistance and the proliferation of anaerobic pathogens; soil compaction and poor aeration can also inhibit root development.

[0006] Existing pesticide application equipment typically applies pesticides to the ground surface or leaves, making it difficult to precisely control plant root diseases. Alternatively, it requires manual application of the pesticide application device into the soil, resulting in a large workload and low efficiency.

[0007] The present invention addresses the above-mentioned technical problems. Summary of the Invention

[0008] In view of the existing technical problems, the present invention provides a pesticide application device and method for preventing and controlling plant root diseases, so as to solve the problems in the prior art.

[0009] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0010] A pesticide application device for preventing and controlling plant root diseases includes an outer shell with wheels at the lower end of the outer shell, a first mounting plate inside the outer shell, and a root application mechanism on the first mounting plate.

[0011] The root application mechanism includes a displacement mechanism and a first medicine tank. The displacement mechanism can move in both horizontal and vertical directions. The lower end of the displacement mechanism is connected to a spiral lifting mechanism, and the lower end of the spiral lifting mechanism is connected to a soil drilling and backfilling mechanism. The spiral lifting mechanism has a flow channel. The upper port of the flow channel is connected to the first medicine tank through a first pipe, and the lower port of the flow channel is connected to the soil drilling and backfilling mechanism. An opening and closing mechanism is provided in the flow channel near its lower port.

[0012] The backfilling mechanism includes a first gear and a second gear rotatably connected to the spiral lifting mechanism. The first gear and the second gear mesh with each other. The first gear is connected to the left half of the drill bit through a first connecting arm, and the second gear is connected to the right half of the drill bit through a second connecting arm. The left half of the drill bit and the right half of the drill bit extend out of the lower end of the outer shell. During the rotation of the first gear and the second gear, the left half of the drill bit and the right half of the drill bit can be engaged or disengaged.

[0013] Preferably, the spiral lifting mechanism includes a spiral column, the lower end of which is connected to a conical barrel, the lower end of which is connected to a hollow column, a first through hole penetrating the middle of the spiral column, the first through hole, the inner cavity of the conical barrel and the inner cavity of the hollow column forming the flow channel, the opening and closing mechanism being located inside the conical barrel near its lower port, the first gear and the second gear being connected inside the hollow column, and the left half drill bit and the right half drill bit extending out of the lower end of the hollow column;

[0014] The outer periphery of the spiral column is provided with a first spiral groove, and the outer shell is provided with a first slider at the position corresponding to the spiral column. The first slider is slidably engaged with the first spiral groove. The outer periphery of the hollow column is provided with a second spiral groove, and the outer shell is provided with a second slider at the position corresponding to the hollow column. The second slider is slidably engaged with the second spiral groove.

[0015] With this configuration, when the displacement mechanism drives the spiral lifting mechanism to move vertically, the first slider slides into the first spiral groove, and the second slider slides into the second spiral groove, realizing the spiral lifting of the spiral lifting mechanism, causing the liquid medicine to move and shake in the flow channel for further mixing.

[0016] Preferably, the displacement mechanism includes a first rack and a third gear disposed horizontally on the first mounting plate. The third gear meshes with a second rack. The second rack is vertically connected to the upper end of the spiral lifting mechanism. A fourth gear is rotatably connected to the second rack, and the fourth gear meshes with the first rack. The length of the third gear is the same as the length of the first rack.

[0017] With this configuration, the fourth gear meshes with the first rack, and when the fourth gear rotates, it drives the second rack and the spiral lifting mechanism to move horizontally to adjust the horizontal distance between the root application mechanism and the plant. The third gear meshes with the second rack, and when the third gear rotates, it drives the second rack and the spiral lifting mechanism to move vertically.

[0018] Preferably, it also includes a shaking mechanism, which includes a second mounting plate disposed within the outer casing. A first rotating shaft is rotatably connected to the second mounting plate in the vertical direction. The first rotating shaft is connected to a connecting block via an eccentric block, and the connecting block is connected to the first medicine container.

[0019] With this setup, when in use, the rotation of the first rotating shaft drives the eccentric block, connecting block, and the first medicine container to rotate as a whole. Due to the design of the eccentric block, the first medicine container shakes during the rotation, further mixing the liquid medicine inside the first medicine container.

[0020] Preferably, a drive wheel is rotatably connected to the first mounting plate, which meshes with a first driven wheel and a second driven wheel respectively. The central axis of the first driven wheel is connected to the central axis of the third gear through a bevel gear set, and the second driven wheel is connected to the first rotating shaft.

[0021] With this configuration, the rotation of the driving wheel simultaneously drives the rotation of the first driven wheel and the second driven wheel. The rotation of the first driven wheel drives the bevel gear set and the third gear to rotate, thereby realizing the vertical movement of the screw lifting mechanism. The rotation of the second driven wheel drives the first rotating shaft to rotate, thereby realizing the rotation and shaking of the first medicine tank to prevent pesticide deposition.

[0022] Preferably, the device further includes a sampling mechanism, which includes a mounting bracket connected to the outer side of the housing near its lower end. A first movable frame is movably connected to the mounting bracket in the vertical direction. A third rack is provided on both sides of the mounting bracket in the vertical direction. A fifth gear is provided on both sides of the first movable frame and meshes with the third rack. A fourth rack is provided on both sides of the first movable frame in the vertical direction and meshes with a sixth gear. The sixth gear is provided on both sides of a second movable frame. A fifth rack is provided on both sides of the second movable frame in the vertical direction and meshes with the fifth gear. The sixth gear also meshes with the sixth rack. The sixth rack is provided on both sides of the third movable frame in the vertical direction. An annular blade is provided at the bottom of the third movable frame, with the lower end of the annular blade extending beyond the lower end of the third movable frame. A transverse cutting blade is also provided at the bottom of the third movable frame, located above the annular blade.

[0023] With this configuration, when the first moving frame moves vertically, the third rack meshes with the fifth gear, causing the fifth gear to rotate. The fifth rack meshes with the fifth gear, causing the second moving frame to move vertically. The second moving frame is equipped with a sixth gear, which meshes with the sixth rack, causing the third moving frame to move vertically. When the third moving frame extends downward, the annular blade cuts the soil with roots vertically. Then, the transverse blade extends and cuts the soil with roots after the annular blade has cut it horizontally. After the cutting is completed, the first, second, and third moving frames move back to their original positions in the opposite direction. Then, the soil with roots is removed, making it easier to observe the condition of the plant roots for precise pesticide application.

[0024] Preferably, the system further includes a soil loosening mechanism, which includes connecting arms connected to both sides of the outer casing. One end of each connecting arm is rotatably connected to the outer casing, and the other end is connected to a soil loosening wheel. A baffle is rotatably connected to the connecting arm and is located between the soil loosening wheel and the outer casing. A soil crushing wheel is rotatably connected to the baffle and is located between the baffle and the soil loosening wheel. The soil crushing wheel rotates in the opposite direction to the soil loosening wheel.

[0025] With this setup, the loosening wheel turns over the soil, and the turned-over soil clods are thrown out along the tangential direction of the loosening wheel. Then the crushing wheel rotates, and because the crushing wheel and the turning wheel rotate in different directions, they will generate opposite forces to crush the soil clods. The crushed soil clods and the soil that has not been consolidated into clods fall into the field through the gap between the crushing wheel and the baffle.

[0026] Preferably, it also includes a leaf spraying mechanism, which includes a hollow fixing rod fixed to the outer shell, a liquid storage sleeve sleeved on the hollow fixing rod, a liquid storage cavity inside the liquid storage sleeve, a plurality of hollow support rods distributed circumferentially on the liquid storage sleeve, a spraying hose passing through the hollow support rod, one end of the spraying hose communicating with the liquid storage cavity, and the other end connected to a nozzle;

[0027] The first mounting plate is provided with a second medicine tank, which is equipped with a pressure pump. The outlet of the pressure pump is connected to the liquid storage chamber through a second pipe, which passes through the hollow fixing rod.

[0028] With this setup, when the leaves need to be sprayed, the pressure pump starts, the liquid in the second tank enters the storage chamber through the second pipe, and then is sprayed out through the spray hose and nozzle.

[0029] Preferably, the upper end of the hollow fixing rod is connected to a fixing seat, and the fixing seat has fixing rods distributed along its circumference that correspond to the positions of the hollow support rods. One end of each fixing rod is connected to the fixing seat, and the other end is connected to the hollow support rod at the corresponding position.

[0030] This design uses fixed support rods to support and fix the hollow support rods, preventing them from deflecting or falling off during spraying.

[0031] A method for applying pesticides to control plant root diseases, using the aforementioned pesticide application equipment for controlling plant root diseases, includes the following steps:

[0032] Step 1: Dig out the plant roots with soil attached and observe to determine if there are any diseases. If the roots are found to be diseased, push the above-mentioned application equipment for preventing and controlling plant root diseases into the field.

[0033] Step 2: The displacement mechanism first moves horizontally to move the root application mechanism to a position close to the plant. Then, the displacement mechanism moves vertically. At this time, the left and right half of the drill bit are engaged. As the displacement mechanism drives the left and right half of the drill bit to move downward, the left and right half of the drill bit drill into the soil.

[0034] Step 3: The first medicine tank is activated. The medicine liquid in the first medicine tank enters the flow channel through the first pipe. Then, the first gear and the second gear rotate to drive the left half drill bit and the right half drill bit to open. At this time, the opening and closing mechanism is opened, and the medicine liquid enters the plant root system.

[0035] Step four: After the application of the pesticide is completed, the displacement mechanism drives the root application mechanism to move upward. During the upward movement, the first gear and the second gear rotate in opposite directions, causing the left half of the drill bit and the right half of the drill bit to engage. During the engagement process, the soil is backfilled into the root application position.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention can better match the position of plant roots by moving the root application mechanism in both vertical and horizontal directions. At the same time, when the root application mechanism moves downward in the vertical direction, it drives the soil backfilling mechanism to rotate into the soil. Then, the rotation of the first gear and the second gear drives the left half of the drill bit and the right half of the drill bit to open, and the medicine is applied into the root soil, realizing precise application of medicine to the plant roots. Moreover, the reverse rotation of the first gear and the second gear can drive the left half of the drill bit and the right half of the drill bit to engage. During the engagement process, the soil is backfilled into the root application position, which reduces labor intensity and improves application efficiency and effect. Attached Figure Description

[0050] As attached Figure 1 - Appendix Figure 11 The device shown is a pesticide application device for preventing and controlling plant root diseases. It includes an outer shell 1, with a walking wheel 10 at the lower end of the outer shell 1. A first mounting plate 50 is provided in the horizontal direction inside the outer shell 1, and a root application mechanism is provided on the first mounting plate 50.

[0051] refer to Figure 2 , Figure 3 and Figure 5 The root application mechanism includes a displacement mechanism and a first medicine tank 11. The displacement mechanism can move in both horizontal and vertical directions. The lower end of the displacement mechanism is connected to a screw lifting mechanism, and the lower end of the screw lifting mechanism is connected to a soil drilling and backfilling mechanism. The screw lifting mechanism is provided with a flow channel. The upper port of the flow channel is connected to the first medicine tank 11 through a first pipe 13, and the lower port of the flow channel is connected to the soil drilling and backfilling mechanism. An opening and closing mechanism 68 is provided in the flow channel near its lower port.

[0052] The displacement mechanism includes a first rack 51 and a third gear 54 arranged horizontally on a first mounting plate 50. The third gear 54 is mounted on the first mounting plate 50 via a bracket 540. The central axis of the first rack 51 and the third gear 54 are parallel. The third gear 54 meshes with a second rack 53. The second rack 53 is vertically connected to the upper end of the screw lifting mechanism. A fourth gear 52 is rotatably connected to the second rack 53. The fourth gear 52 meshes with the first rack 51. The length of the third gear 54 is the same as the length of the first rack 51.

[0053] A drive wheel 57 is rotatably connected to the first mounting plate 50. The drive wheel 57 meshes with the first driven wheel 56 and the second driven wheel 88 respectively. The central axis of the first driven wheel 56 is connected to the central axis of the third gear 54 through the bevel gear set 55. The second driven wheel 88 is connected to the first rotating shaft 87.

[0054] refer to Figure 4 and Figure 5 The spiral lifting mechanism includes a spiral column 61, with the lower end of a second rack 53 connected to the upper end of the spiral column 61. The lower end of the spiral column 61 is connected to a conical barrel 63, and the lower end of the conical barrel 63 is connected to a hollow column 65. A first through hole 67 passes through the middle of the spiral column 61. The first through hole 67, the inner cavity of the conical barrel 63, and the inner cavity of the hollow column 65 form a flow channel. An opening and closing mechanism 68 is located inside the conical barrel 63 near its lower end. A first gear 71 and a second gear 72 are rotatably connected inside the hollow column 65, and the left half-drill bit 75 and the right half-drill bit 76 extend out of the lower end of the hollow column 65. The axis of the spiral column 61, the central axis of the conical barrel 62, and the axis of the hollow column 65 are all on the same straight line.

[0055] The outer periphery of the spiral column 61 is provided with a first spiral groove 62, and the outer shell 1 is provided with a first slider (not shown in the figure) corresponding to the position of the spiral column 61. The first slider is slidably engaged with the first spiral groove 62. The outer periphery of the hollow column 65 is provided with a second spiral groove 66, and the outer shell 1 is provided with a second slider (not shown in the figure) corresponding to the position of the hollow column 65. The second slider is slidably engaged with the second spiral groove 66. During the lifting process, the first slider is slidably engaged with the first spiral groove 62, and the second slider is slidably engaged with the second spiral groove 66 to realize the spiral lifting mechanism.

[0056] Meanwhile, in order to ensure the stability of the lifting process of the screw lifting mechanism, a limiting ring 610 is fitted on the screw column 61. The screw column 61 and the limiting ring 610 are in movable cooperation. The limiting ring 610 does not affect the lifting process of the screw column 61. A hydraulic rod 611 is symmetrically provided on both sides of the limiting ring 610. When the screw lifting mechanism deviates during the lifting process, the hydraulic rod 611 on the deviated side is compressed and the hydraulic rod 611 on the other side is extended.

[0057] refer to Figure 7 and Figure 3 The backfilling drilling mechanism includes a first gear 71 and a second gear 72 rotatably connected to a screw lifting mechanism. The first gear 71 and the second gear 72 mesh with each other. The first gear 71 is connected to the left half drill bit 75 through the first connecting arm 73, and the second gear 72 is connected to the right half drill bit 76 through the second connecting arm 74. The left half drill bit 75 and the right half drill bit 76 extend out of the lower end of the outer shell 1 and extend downward out of the lower end of the outer shell 1. During the rotation of the first gear 71 and the second gear 72, the left half drill bit 75 and the right half drill bit 76 can be engaged or disengaged. When the left half drill bit 75 and the right half drill bit 76 are engaged together, they form a drill bit structure with a pointed tip. In this way, when the screw lifting mechanism descends, the drill bit structure formed by the engagement of the left half drill bit 75 and the right half drill bit 76 can drill into the soil. The rotation of the first gear 71 and the second gear 72 causes the left half-drill bit 75 and the right half-drill bit 76 to open, and the pesticide solution immediately enters the soil. After the pesticide application is completed, during the upward movement of the spiral lifting mechanism, the first gear 71 and the second gear 72 rotate in opposite directions, causing the left half-drill bit 75 and the right half-drill bit 76 to engage. The left half-drill bit 75 and the right half-drill bit 76 can then drive the soil back into the root application position, preventing the evaporation of moisture and pesticide solution from the soil at the application position.

[0058] The present invention also includes a shaking mechanism, please refer to [reference needed]. Figure 6 and Figure 3 The shaking mechanism includes a second mounting plate 81 disposed inside the outer casing 1. The second mounting plate 81 is arranged in the horizontal direction. A first rotating shaft 87 is rotatably connected to the second mounting plate 81 in the vertical direction via a bearing. The first rotating shaft 87 is connected to a connecting block 85 via an eccentric block 83. The connecting block 85 is connected to the first medicine container 11.

[0059] This embodiment also includes a sampling mechanism 2, for reference. Figure 1 , Figure 9 and Figure 10 The sampling mechanism 2 includes a mounting frame 21 connected to the outer side of the outer shell 1 near its lower end. A first movable frame 22 is movably connected to the mounting frame 21 in the vertical direction. A motor 27 is mounted on the mounting frame 21. The output shaft of the motor 27 is connected to a lead screw 28. The lead screw 28 is set vertically. A lead screw slider 29 is slidably sleeved on the lead screw 28. The lead screw slider 29 is fixedly connected to the middle of the top plate of the first movable frame 22. The motor 27 drives the first movable frame 22 to move up and down.

[0060] In this embodiment, the first movable frame 22 includes a first top plate, a first back plate, and first side plates connected to both sides of the first top plate and the first back plate. The second movable frame 23 includes a second back plate and second side plates disposed on both sides of the second back plate. The third movable frame 24 includes a third back plate, a bottom plate, and third side plates connected to both sides of the third back plate. The two sides of the bottom plate are respectively connected to the bottom ends of the two third side plates, and the rear side of the bottom plate is connected to the third back plate.

[0061] The mounting bracket 21 has two vertically aligned third racks 210 on both sides, with two third racks 210 respectively located on the two first side plates. The first movable frame 22 has two fifth gears 220 on both sides that mesh with the third racks 210. The first movable frame 22 also has two vertically aligned fourth racks 221 on both sides. The two fifth gears 220 and two fourth racks 221 are respectively located on the two second side plates. The fourth rack 221 meshes with a sixth gear 231, which is located on both sides of the second movable frame 23. The second movable frame 23 also has two vertically aligned fifth racks 230 on both sides, which mesh with the fifth gears 220. The two sixth gears 231 and two fifth racks 230 are respectively located on the two third side plates. The sixth gear 231 also meshes with the sixth racks. The third moving frame 240 is engaged with a sixth rack 240, which is vertically positioned on both sides of the third moving frame 24. Two sixth racks 240 are respectively positioned on the two third side plates. The bottom of the third moving frame 24 is provided with an annular blade 26, which is positioned on the bottom plate of the third moving frame 24. The lower end of the annular blade 26 extends beyond the lower end of the third moving frame 24, with the blade facing downward. Thus, during the downward movement of the third moving frame 24, the annular blade 26 contacts the soil first and cuts the soil longitudinally. The bottom plate of the third moving frame 24 is also provided with a transverse cutting blade 25, which is positioned above the annular blade 26. The transverse cutting blade 25 can be a blade positioned horizontally. The blade is driven by a motor to move horizontally and cuts the soil laterally. The transverse cutting blade 25 can also be designed as a scissor-like structure, with one end of the two blades hinged together. This allows the soil to be cut laterally when the two blades rotate. The design of the transverse cutting blade 25 can also refer to the existing opening and closing mechanism structure; simply replace the central opening and closing plate with the blades. The blade edges should face the center, thus achieving transverse cutting of the soil. The specific design can be chosen according to the actual situation, as long as it can cut the soil laterally. After longitudinal and transverse cutting, the soil will be located separately in the third moving frame 24, which can then be picked up by a person for observation and assessment to determine if there are any diseases.

[0062] This embodiment also includes a soil loosening mechanism 3, please refer to... Figure 8 and Figure 1 The soil loosening mechanism 3 includes connecting arms 32 connected to both sides of the outer shell 1. One end of the connecting arm 32 is rotatably connected to the outer shell 1, and the other end is connected to a soil loosening wheel 33. A baffle 34 is rotatably connected to the connecting arm 32. The baffle 34 is located between the soil loosening wheel 33 and the outer shell 1. A soil crushing wheel 36 is rotatably connected to the baffle 34. The soil crushing wheel 36 is located between the baffle 34 and the soil loosening wheel 33. The center line of the soil crushing wheel 36 is parallel to the center line of the soil loosening wheel 33, and the soil crushing wheel 36 and the soil loosening wheel 33 rotate in opposite directions.

[0063] After the loosening wheel 33 loosens the soil, soil clods are thrown out along the tangential direction of the loosening wheel 33. The crushing wheel 36 rotates, and because the crushing wheel 36 and the loosening wheel 33 rotate in opposite directions, they generate opposing forces that crush the soil clods. The crushed soil clods and unconsolidated soil enter the soil through the gap between the crushing wheel 36 and the baffle 34. This prevents soil compaction and poor aeration, which can obstruct root respiration and cause root rot due to water accumulation.

[0064] This embodiment also includes a leaf application mechanism, see reference. Figure 11 and Figure 1 , Figure 2 The leaf application mechanism includes a hollow fixing rod 41 fixed vertically on the outer shell 1. A liquid storage sleeve 42 is fixedly sleeved on the hollow fixing rod 41. The liquid storage sleeve 42 has a liquid storage cavity inside. Multiple hollow support rods 43 are distributed around the circumference of the liquid storage sleeve 42. A spraying hose 44 is inserted through the hollow support rod 43. One end of the spraying hose 44 is connected to the liquid storage cavity, and the other end is connected to a nozzle 45.

[0065] A second medicine tank 12 is mounted on the first mounting plate 50. The second medicine tank 12 contains a pressure pump, the outlet of which is connected to a liquid storage chamber via a second pipe 14. The second pipe 14 passes through a hollow fixing rod 41. The upper end of the hollow fixing rod 41 is connected to a fixing seat 47. The fixing seat 47 has fixing supports 46 distributed circumferentially around it, corresponding to the positions of the hollow support rods 43. One end of each fixing support 46 is connected to the fixing seat 47, and the other end is connected to the corresponding hollow support rod 43.

[0066] A method for applying pesticides to control plant root diseases, using... Figures 1-11 A pesticide application device for controlling plant root diseases includes the following steps:

[0067] Step 1: When the motor 27 drives the first moving frame 22 to move vertically, the third rack 210 meshes with the fifth gear 220, causing the fifth gear 220 to rotate. The fifth rack 230 meshes with the fifth gear 220, causing the second moving frame 23 to move vertically. The second moving frame 23 is equipped with a sixth gear 231, which meshes with the sixth rack 240, causing the third moving frame 24 to move vertically. When the third moving frame 24 extends downward, the annular blade 26 cuts the soil with roots vertically. Then, the transverse blade 25 extends horizontally to cut the soil with roots cut by the annular blade 26. After the cutting is completed, the first moving frame 22, the second moving frame 23, and the third moving frame 24 move back to their original positions in the opposite direction. Then, the soil with roots is removed and manually inspected to determine if there are any diseases. If the roots are found to be diseased, then pesticide application is performed.

[0068] Step two: The fourth gear 52 rotates, driving the second rack 53 and the spiral lifting mechanism to move horizontally, adjusting the horizontal distance between the root application mechanism and the plant. Then, the driving wheel 57 drives the first driven wheel 56 and the second driven wheel 88 to rotate. The first driven wheel 56 drives the third gear 54 to rotate, which in turn drives the second rack 53 and the spiral lifting mechanism to move vertically. At this time, the left half drill bit 75 and the right half drill bit 76 are engaged. As the displacement mechanism drives the left half drill bit 75 and the right half drill bit 76 to move downward, the left half drill bit 75 and the right half drill bit 76 drill into the soil. At the same time, the second driven wheel 88 drives the first rotating shaft 87 and its eccentric block 83, connecting block 85 and the first medicine tank 11 to rotate as a whole, so as to shake the medicine liquid in the first medicine tank 11 evenly.

[0069] Step 3: The first medicine tank 11 is activated. The medicine liquid in the first medicine tank 11 enters the flow channel through the first pipe 13. Then, the first gear 71 and the second gear 72 rotate to drive the left half drill bit 75 and the right half drill bit 76 to open. At this time, the opening and closing mechanism 68 is opened, and the medicine liquid enters the plant root system.

[0070] Step 4: After the application of the pesticide is completed, the displacement mechanism drives the root application mechanism to move upward. During the upward movement, the first gear 71 and the second gear 72 rotate in opposite directions, causing the left half drill bit 75 and the right half drill bit 76 to engage. During the engagement process, the soil is backfilled into the root application position.

[0071] Step 5: When it is necessary to spray the plant leaves, start the pressure pump in the second medicine tank 12. The medicine in the second medicine tank 12 is sprayed onto the plant leaves through the second pipe 14, the spray hose 44 and the nozzle 45.

[0072] After all the pesticide application is completed, when it is necessary to turn the soil, the loosening wheel 33 rotates to turn the soil up, and the turned soil clods are thrown out along the tangential direction of the turning wheel. Then the crushing wheel 36 rotates. Since the crushing wheel 36 and the loosening wheel 33 rotate in opposite directions, they will generate opposing forces to crush the turned soil clods. The crushed soil clods and the soil that has not been consolidated into clods fall into the field through the gap between the crushing wheel 36 and the baffle 34.
