Description

Technical Field

[0001] This invention relates to the field of grape cultivation technology, and more specifically to a fertilization device for grape cultivation. Background Technology

[0002] Grapes are woody vines belonging to the genus *Vitis* in the family Vitaceae. Their twigs are cylindrical with longitudinal ridges, hairless or sparsely pubescent, and their leaves are ovate. Their panicles are dense or sparse, with well-developed basal branches. Their fruits are spherical or elliptical. They flower from April to May and fruit from August to September.

[0003] During the grape growing season, fertilization should be carried out according to the growth status of the grapes and the fertility of the soil. Fertilization can be carried out in two ways: topdressing at the roots of the grape seedlings and topdressing on the leaves. Different fertilization methods are suitable for different situations.

[0004] Chinese patent application number CN202221796645.7 discloses a fertilization device for grape cultivation, belonging to the field of grape technology. It addresses the problem that in existing grape cultivation processes, fertilization is necessary, but due to the high height of the grape trellis, the fertilization position and height cannot be adjusted according to the different root positions of the grapevines, resulting in reduced fertilization effectiveness. The device includes a support base with symmetrically arranged movable seats fixed to its bottom side wall. Rollers are installed on the bottom side wall of the movable seats. Symmetrically arranged guide plates are fixed to the outer walls of both sides of the support base, and a slidable storage box is connected between the side walls of the guide plates that are close to each other. This utility model, through the combination of a first shaft, a second shaft, stirring blades, adjusting gears, adjusting racks, a drive motor, a circulation plate, and a circulation gear, can adjust the fertilization spray position according to the different heights of the grapevines. During the height adjustment process, it can automatically stir and mix waste materials, improving practicality.

[0005] Chinese patent application CN202110462629.8 discloses a fertilizer application device specifically for grape cultivation, including a carriage and: a mixing mechanism movably connected to the carriage for proportioning fertilizer and breaking up large fertilizer clumps; a fertilizer application mechanism movably connected to the carriage for depth-controlled fertilization of the grapevines, the fertilizer application mechanism including a soil-breaking component and a controllable component; the soil-breaking component for rotary soil breaking at the rootstock of the grapevines, and the controllable component for depth adjustment of the soil-breaking component by converting the rotary motion into linear reciprocating motion; and a drive system movably installed on the carriage for driving the mixing mechanism to proportion and break up the fertilizer and driving the fertilizer application mechanism to fertilize the grapevines. This invention can proportion, mix, break up, and apply fertilizer, making fertilization environmentally friendly and reliable.

[0006] However, of the two existing technologies mentioned above, one uses soil breaking for root fertilization and the other uses spraying for foliar fertilization. When different fertilization methods are required, different equipment is needed, resulting in a certain waste of resources. The equipment functions are relatively simple and cannot be designed to combine root fertilization and foliar fertilization.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0047] like Figures 1 to 15 As shown, the present invention provides a fertilization device for grape cultivation, comprising: a vehicle body 1; a mounting plate 2 fixedly installed on the vehicle body 1; a root fertilization mechanism 3 for fertilizing the grape roots; and a foliar fertilization mechanism 4 for fertilizing the grape leaves.

[0048] The vehicle body 1 is preferably electrically driven, and angle irons are installed on the wheels of the vehicle body 1 to prevent slippage when the vehicle body 1 moves in the soil.

[0049] The root fertilization mechanism 3 includes: a storage box 31 for storing fertilizer, the storage box 31 being fixedly installed on the mounting plate 2, a discharge pipe 32 communicating with the storage box 31, a guide pipe 33 sleeved and installed on the discharge pipe 32, a control component 34 for controlling the amount of fertilizer discharged, and a soil breaking component 35 for breaking up the soil.

[0050] When fertilizing the roots of grapes, the soil needs to be broken up to facilitate the transport of fertilizer into the soil, thereby making it easier for the grape roots to absorb it.

[0051] The soil-breaking component 35 includes: a power source 351 fixedly installed on the storage tank 31; a movable frame 352 fixedly installed on the movable end of the power source 351; and telescopic rods 359 that limit the movement of the movable frame 352. Two telescopic rods 359 are provided, symmetrically arranged on both sides of the power source 351. The movable ends of both telescopic rods 359 are fixedly connected to the movable frame 352. The fixed end of one telescopic rod 359 is fixedly connected to the storage tank 31, and the fixed end of the other telescopic rod 359 is fixedly connected to the liquid storage tank 4. 1. A fixed connection is made to the connecting pipe 353 fixedly installed on the movable frame 352, a movable pipe 354 rotatably installed on the outside of the connecting pipe 353, a fixed pipe 355 inserted and installed on the vehicle body 1, a guide groove 356 opened in the fixed pipe 355, a rolling element 357 rotatably installed on the movable pipe 354, and a soil drilling element 358 installed on the movable pipe 354; the rolling element 357 is rotatably installed in the guide groove 356; the connecting pipe 353 is connected to the guide pipe 33; the guide pipe 33 is fixedly connected to the movable frame 352.

[0052] When the ground is broken, the power source 351 is started, which drives the movable frame 352 to move downward. The movable frame 352 drives the connecting pipe 353 to move downward. The connecting pipe 353 drives the movable pipe 354 to move downward. The movable pipe 354 drives the rolling element 357 to roll in the guide groove 356. The guide groove 356 is composed of a vertical groove and a spiral groove. The vertical groove and the spiral groove are connected to each other. That is, when the rolling element 357 moves along the path of the guide groove 356, it first moves downward along the vertical groove and then enters the spiral groove. Under the guidance of the spiral groove, the movable pipe 354 rotates. Thus, when the movable pipe 354 moves along the path of the guide groove 356, it first moves downward along the axial direction of the fixed pipe 355 and then rotates circumferentially along the fixed pipe 355.

[0053] It should be noted that the rolling element 357 is preferably a bull's eye ball bearing.

[0054] The movement of the movable tube 354 can drive the movement of the drilling component 358. The drilling component 358 includes: a storage groove opened on the movable tube 354, a connecting rod 3582 movably installed in the storage groove, a connecting spring 3581 fixedly installed between one end of the connecting rod 3582 and the inner wall of the storage groove, a drill bit 3583 fixedly installed at the other end of the connecting rod 3582, an arc-shaped block 3584 fixedly installed on the drill bit 3583, and a soil-breaking groove 3585 opened on the drill bit 3583. Multiple storage grooves are provided, and each storage groove is correspondingly provided with a connecting rod 3582 and a connecting spring 3581. All connecting rods 3582 are fixedly connected to the drill bit 3583.

[0055] Specifically, when the movable tube 354 moves downward along the axial direction of the fixed tube 355, it drives the connecting rod 3582 to move downward. The connecting rod 3582 drives the drill bit 3583 to move downward. When the drill bit 3583 comes into contact with the ground, it is resisted by the soil and moves downward slowly. At this time, the movable tube 354 continues to move downward along the axial direction of the fixed tube 355 and drives the connecting spring 3581 to compress. At this time, the connecting rod 3582 gradually retracts into the receiving groove. When the movable tube 354 comes into contact with the drill bit 3583, it drives the drill bit 3583 to continue to move downward. Then the rolling element 357 enters the spiral groove. At this time, the movable tube 354 rotates, which in turn drives the drill bit 3583 to rotate. The rotating head drills into the soil, thereby achieving the function of breaking the soil.

[0056] Because the drill bit 3583 has a soil-breaking groove 3585, the cutting effect on the soil is improved, thereby increasing the soil-breaking efficiency.

[0057] When the rolling element 357 moves to the bottom of the spiral groove, the soil breaking is completed. At this time, the power source 351 drives the movable frame 352 to move upward and reset. The movable frame 352 drives the connecting tube 353 to move upward. The connecting tube 353 drives the movable tube 354 to move upward. The movable tube 354 drives the drilling element 358 to reset upward. When the movable tube 354 moves upward, it does not have a blocking effect on the drill bit 3583. At this time, the elastic force of the connecting spring 3581 can drive the connecting rod 3582 to reset. The connecting rod 3582 drives the drill bit 3583 to reset, so that the drill bit 3583 separates from the movable tube 354.

[0058] It should be noted that the power source 351 is preferably a pneumatic cylinder or a hydraulic cylinder.

[0059] When the power source 351 drives the movable frame 352 to move downward, the movable frame 352 drives the connecting pipe 353 to move downward, and simultaneously drives the guide pipe 33 to move downward. When the guide pipe 33 moves downward, it drives the control component 34 to operate. The control component 34 includes: a mounting groove opened on the discharge pipe 32, a movable rod 344 movably installed in the mounting groove, a return spring 345 fixedly installed between one end of the movable rod 344 and the inner wall of the mounting groove, and a fixedly installed at the other end of the movable rod 344. The components include a connecting strip 343, a support rod 342 fixedly installed on the connecting strip 343, a sealing block 341 fixedly installed at the end of the support rod 342, an abutment rod 346 movably installed inside the guide pipe 33, a guide block 347 fixedly installed on the abutment rod 346, and a reset component 348 that drives the abutment rod 346 to reset. In its initial state, the sealing block 341 can seal the inner cavity of the discharge pipe 32. The top of the sealing block 341 is arc-shaped, which facilitates the fertilizer to slide down from the top of the sealing block 341.

[0060] Specifically, when the guide tube 33 moves downward, it can drive the reset component 348 to move downward, which in turn can drive the abutment rod 346 to move downward. The reset component 348 includes: a mounting shell 3481 fixedly installed in the guide tube 33, a slide rod 3482 fixedly installed in the mounting shell 3481, a slider 3483 slidably installed on the slide rod 3482, and a reset spring 3484 fixedly installed between the slider 3483 and the inner wall of the mounting shell 3481; the slider 3483 is fixedly connected to the abutment rod 346.

[0061] When the abutment rod 346 moves downward, the linkage tube 353 drives the movable tube 354 to move along the path of the guide groove 356. When the bottom end of the movable tube 354 abuts against the drill bit 3583, the abutment rod 346 abuts against the connecting strip 343 and drives the guide block 347 to move downward. When the movable tube 354 drives the drill bit 3583 to continue moving downward, the abutment rod 346 drives the connecting strip 343 to move downward. The connecting strip 343 drives the support rod 342 and the movable rod 344 to move downward. The support rod 342 drives the sealing block 341 to move downward. At this time, the sealing block 341 does not have a sealing effect on the inner cavity of the discharge pipe 32. The fertilizer in the storage box 31 enters the movable tube 354 in sequence through the discharge pipe 32, the guide pipe 33, and the linkage tube 353. At the same time, the movable rod 344 drives the return spring 345 to stretch.

[0062] As in the appendix of this invention Figure 7 As shown, the discharge pipe 32 is divided into a thin pipe section and a thick pipe section. The thin pipe section is located above the thick pipe section, and the sealing block 341 is located in the thick pipe section.

[0063] As the abutment rod 346 drives the connecting bar 343 to continue moving downwards, the guide block 347 abuts against the outer side of the thick pipe section. Since the bottom of the guide block 347 is inclined, after it abuts against the outer side of the thick pipe section, the guide block 347 is subjected to an abutment force, causing the abutment rod 346 to move. The abutment rod 346 drives the slider 3483 to slide along the axial direction of the slide rod 3482 within the mounting housing 3481, and compresses the second return spring 3484. As the abutment rod 346 slides along the axial direction of the slide rod 3482, the bottom end of the abutment rod 346 gradually abuts against the connecting bar 343. 43 Separation: When the guide block 347 approaches the vertical surface of the discharge pipe 32 and abuts against the outer side of the thick section of the discharge pipe 32, the abutting rod 346 is completely separated from the connecting strip 343. At this time, through the elastic force of the reset spring 3484, the movable rod 344 can be driven to reset upward. The movable rod 344 drives the connecting strip 343 to reset upward. The connecting strip 343 drives the support rod 342 to reset upward. The support rod 342 drives the sealing block 341 to reset upward, so that the sealing block 341 seals the inner cavity of the discharge pipe 32 again. At this time, the fertilizer cannot be discharged from the discharge pipe 32.

[0064] Since the downward movement distance of the abutment rod 346 is the same each time, the time during which the sealing block 341 does not seal the discharge pipe 32 is the same each time. This ensures that the fertilizer is discharged at the same time each time, thus achieving quantitative fertilizer discharge. This results in uniform fertilizer application, avoiding excessive or insufficient fertilizer application that could affect grape growth. Furthermore, it eliminates the need for manual control of fertilizer application, improving ease of use.

[0065] When the bottom end of the movable tube 354 abuts against the top of the drill bit 3583, the fertilizer entering the movable tube 354 cannot be discharged. When the rolling element 357 moves to the bottom end of the spiral groove, the soil breaking is completed. At this time, the power source 351 drives the movable frame 352 to reset upward. The movable frame 352 drives the guide tube 33 and the connecting tube 353 to reset upward. At this time, the guide tube 33 drives the reset element 348 to move upward. The reset element 348 drives the abutment rod 346 to move upward. The abutment rod 346 drives the guide block 347 to move upward. When the guide block 347 separates from the coarse pipe section, the elastic force of the reset spring 3484 drives the abutment rod 346 and the guide block 347 to reset, preparing for subsequent use.

[0066] At the same time, the linkage tube 353 drives the movable tube 354 to move upward, and the movable tube 354 drives the drilling component 358 to reset upward. When the movable tube 354 moves upward, it no longer has a blocking effect on the drill bit 3583. At this time, the connecting spring 3581 can drive the connecting rod 3582 to reset through the elastic force. The connecting rod 3582 drives the drill bit 3583 to reset, so that the drill bit 3583 separates from the movable tube 354. At this time, the fertilizer can be discharged from the bottom of the movable tube 354. Since the top of the drill bit 3583 is fixedly installed with an arc-shaped block 3584, when the fertilizer falls on the top of the arc-shaped block 3584, it will quickly slide into the soil, thereby avoiding the accumulation of fertilizer on the top of the drill bit 3583 and improving the discharge efficiency.

[0067] Furthermore, the drill bit 3583 is equipped with a soil-breaking groove 3585, through which fertilizer can fall into the soil, thereby further improving the discharge efficiency.

[0068] In addition, during the upward reset process of drill bit 3583, when the movable tube 354 moves along the path of the spiral groove, it can drive drill bit 3583 to rotate. By utilizing the centrifugal force, it is easier to throw out the fertilizer at the top of drill bit 3583, thereby further improving the discharge efficiency.

[0069] In this invention, the root fertilization mechanism 3 enables the quantitative application of fertilizer while breaking the soil, thus ensuring uniform fertilization and preventing excessive or insufficient fertilization that could affect grape growth. Furthermore, it eliminates the need for manual control of the fertilization amount, improving ease of use. On the other hand, it enables the rapid delivery of fertilizer to the soil, preventing fertilizer accumulation at the top of the drill bit 3583 and improving discharge efficiency.

[0070] The foliar fertilization mechanism 4 includes: a storage tank 41 for storing foliar fertilizer concentrate and water, the storage tank 41 being fixedly connected to the mounting plate 2; a collection tank 42 fixedly mounted on the vehicle body 1; a collection and discharge assembly 43 that simultaneously draws foliar fertilizer concentrate and water from the storage tank and discharges the mixture into the collection tank 42; a nozzle 44; a conveying assembly 45 that transports the mixture in the collection tank 42 to the nozzle 44; and an adjustment assembly 46 that adjusts the spraying range of the nozzle 44.

[0071] A partition is fixedly installed on the inner wall of the storage tank 41, thereby dividing the storage tank 41 into two independent storage spaces. One storage space stores the foliar fertilizer concentrate, and the other storage space stores water. By storing the foliar fertilizer concentrate and water separately, the storage time can be increased. Compared with storing the foliar fertilizer concentrate and water together, this avoids the problem of nutrient loss and decomposition caused by long-term storage of the mixture. At the same time, when using, a certain amount of foliar fertilizer concentrate and water are drawn up separately and mixed, avoiding the problem of excessive mixture leading to waste.

[0072] When applying fertilizer to grape leaves, the foliar fertilizer stock solution needs to be diluted with water first. That is, the foliar fertilizer stock solution and water are mixed into a certain concentration of solution before being sprayed on the leaves so that they can be better absorbed and utilized by the leaves. When applying fertilizer to grape leaves, a certain amount of foliar fertilizer stock solution and water are drawn from the storage tank 41 by the intake and discharge component 43 and stirred to form a mixture of a certain concentration of solution. The mixture is then transported to the collection tank 42.

[0073] The dispensing assembly 43 includes: a sleeve 431 fixedly installed on the storage tank 41; a movable tube 432 slidably installed inside the sleeve 431; the movable tube 432 is fixedly connected to the movable frame 352; a first one-way valve is installed on the movable tube 432; a linkage spring 433 drives the movable tube 432 to reset; one end of the linkage spring 433 is fixedly connected to the storage tank 41; the other end of the linkage spring 433 is fixedly connected to the movable tube 432; and a connecting tube 437 connects the movable tube 432 and the collection tank 42. 437 is preferably a retractable hose, a piston 435 slidably installed in the moving pipe 432, a fixing rod 434 fixedly installed between the piston 435 and the storage tank 41, and a liquid guide pipe 436 connecting the moving pipe 432 and the storage tank 41. Two liquid guide pipes 436 are provided to draw foliar fertilizer stock solution and clean water respectively. The connecting pipe 437 is preferably a retractable hose, and a second one-way valve is installed on both liquid guide pipes 436. A mixing unit 438 is used to mix and stir the foliar fertilizer stock solution and clean water during the liquid inflow and outflow process.

[0074] When the foliar fertilizer concentrate and water are being drawn in, the power source 351 is activated to move the movable frame 352 downwards. The movable frame 352 then moves the moving tube 432 downwards. At this time, the piston 435 slides relative to the moving tube 432, thereby generating suction. At this time, the first one-way valve closes and the second one-way valve opens. The foliar fertilizer concentrate and water enter the moving tube 432 through the corresponding liquid guide tubes 436. At the same time, the mixing unit 438 performs initial stirring and mixing of the foliar fertilizer concentrate and water, so that the foliar fertilizer concentrate and water are mixed evenly.

[0075] When the mixture is discharged, the power source 351 drives the movable frame 352 to move upward, and the movable frame 352 drives the moving pipe 432 to move upward. At this time, the piston 435 slides relative to the moving pipe 432, thereby squeezing the mixture. At this time, the first one-way valve opens and the second one-way valve closes. The mixture is discharged into the collection tank 42 through the connecting pipe 437, thus avoiding the problem of mixture backflow. At the same time, the mixing unit 438 stirs and mixes the foliar fertilizer stock solution and water again. Through two stirring and mixing, the foliar fertilizer stock solution and water are fully mixed, so that the composition of the mixture is consistent, thereby ensuring the nutritional effect of the mixture.

[0076] The mixing unit 438 includes: a linkage rack 4381 fixedly mounted on the sleeve 431; a linkage gear 4382 meshing with the linkage rack 4381; a drive bevel gear 4383 rotatably mounted on the moving tube 432 and coaxially connected to the linkage gear 4382; a driven bevel gear 4384 meshing with the drive bevel gear 4383; an installation strip fixedly mounted inside the moving tube 432; a stirring blade 4385 rotatably mounted on the installation strip and coaxially connected to the driven bevel gear 4384; an inner tube 4386 fixedly mounted inside the moving tube 432; a first one-way valve mounted below the inner tube 4386; and a guide groove 4387 formed on the inner wall of the inner tube 4386.

[0077] Specifically, when the foliar fertilizer stock solution and water are drawn in, the moving tube 432 moves downward and drives the connecting rack 4381 to move downward. The connecting rack 4381 drives the connecting gear 4382 to rotate, which in turn drives the active bevel gear 4383 to rotate. The active bevel gear 4383 drives the driven bevel gear 4384 to rotate, and the driven bevel gear 4384 drives the stirring blade 4385 to rotate, thereby performing the initial stirring and mixing of the foliar fertilizer stock solution and water, so that the foliar fertilizer stock solution and water are mixed evenly.

[0078] When the mixture is discharged, the moving tube 432 moves upward and drives the connecting rack 4381 to move upward. The connecting rack 4381 drives the connecting gear 4382 to rotate, which in turn drives the active bevel gear 4383 to rotate. The active bevel gear 4383 drives the driven bevel gear 4384 to rotate, and the driven bevel gear 4384 drives the stirring blade 4385 to rotate, thereby re-stirring and mixing the foliar fertilizer concentrate and water, further improving the uniformity of the mixture.

[0079] Furthermore, an inner tube 4386 is fixedly installed in the inner cavity of the moving tube 432. The inner cavity of the inner tube 4386 is funnel-shaped, and a guide groove 4387 is opened on the inner wall of the inner tube 4386. When the liquid is discharged, the mixed liquid flows through the guide groove 4387 to the discharge port of the inner tube 4386. Since the discharge port is small, the mixed liquid is mixed again during the process of passing through the discharge port, thereby further improving the uniformity of the mixture.

[0080] In this invention, the intake and discharge component 43 allows for multiple stirring and mixing of the foliar fertilizer concentrate and water during the intake and discharge process, greatly improving the uniformity of the mixture and ensuring that the overall composition of the mixture remains consistent, thereby guaranteeing the nutritional effect of the mixture.

[0081] In addition, when the foliar fertilizer concentrate is mixed with water, the power source 351 is activated to move the movable frame 352 downwards. The movable frame 352 moves the moving pipe 432 downwards, and at the same time, the movable frame 352 moves the connecting pipe 353 downwards, thereby driving the soil drill 358 to break the soil and quantitatively dispensing the fertilizer. When the mixture is discharged, the power source 351 is activated to move the movable frame 352 upwards, and the movable frame 352 moves the moving pipe 432 upwards. At the same time, the soil drill 358 completes breaking the soil, and the movable frame 352 moves the connecting pipe 353 upwards, thereby driving the soil drill 358 upwards. At this time, the fertilizer is delivered into the soil. When the soil drill 358 returns to its original position, the mixture is completely discharged into the collection tank 42, thus preparing for subsequent foliar fertilizer spraying.

[0082] It should be noted that when the foliar fertilizer concentrate is replaced with other agricultural agents, such as pesticides, this invention also has the function of spraying pesticides on grape leaves.

[0083] The conveying assembly 45 includes: a limiting frame 451, a slide plate 452 fixedly mounted on a support plate 4612 and slidably mounted within the limiting frame 451, the limiting frame 451 limiting the slide plate 452, a second power source 453 whose bottom and top of the support plate 4612 are fitted together and drive the slide plate 452 to move, the second power source 453 fixedly mounted on the inner wall of the limiting frame 451, the movable end of the second power source 453 fixedly connected to the slide plate 452, a capsule 454 fixedly mounted between the slide plate 452 and the limiting frame 451, an inlet pipe 455 connecting the capsule 454 and the collection tank 42, and an outlet pipe 456 connecting the capsule 454 and the nozzle 44; a third check valve is installed on the inlet pipe 455 and a fourth check valve is installed on the outlet pipe 456.

[0084] When applying fertilizer to grape leaves, the second power source 453 is activated to move the slide plate 452. When the slide plate 452 compresses the capsule 454, the third one-way valve closes and the fourth one-way valve opens. At this time, the mixed liquid in the capsule 454 is squeezed and enters the nozzle 44 through the outlet pipe 456, and is sprayed onto the leaf surface through the nozzle 44. When the slide plate 452 moves the capsule 454 back to its original position, the third one-way valve opens and the fourth one-way valve closes. At this time, the mixed liquid in the collection tank 42 is drawn into the capsule 454 through the inlet pipe 455. By using the second power source 453 to drive the slide plate 452 to move back and forth, the mixed liquid can be automatically transported and sprayed onto the leaf surface, thus realizing foliar fertilization.

[0085] It should be noted that the preferred power source 2 453 is a cylinder.

[0086] The adjustment assembly 46 includes: a height adjustment unit 461 and an angle adjustment unit 462; the height adjustment unit 461 includes: a power source 3 4611 fixedly installed on the vehicle body 1, a support plate 4612 fixedly installed on the movable end of the power source 3 4611, and a limit plate 4613 fixedly installed on the support plate 4612; a limit frame 451 is fixedly connected to the support plate 4612; a limit opening is opened on the mounting plate 2, and the limit plate 4613 slides in the inner cavity of the limit opening, thereby limiting the up and down movement of the support plate 4612.

[0087] When the spraying height of the nozzle 44 is adjusted, the power source 3 4611 is started to drive the support plate 4612 to move up and down, which in turn drives the nozzle 44 to move up and down, thereby realizing the adjustment of the spraying height of the nozzle 44.

[0088] It should be added here that the preferred power source 34611 is an electric telescopic pole.

[0089] The angle adjustment unit 462 includes: a transmission gear 4622 rotatably mounted on the support plate 4612, a transmission rack 4621 meshing with the transmission gear 4622, a U-shaped plate 4623 coaxially connected with the transmission gear 4622, an arc-shaped plate 4624 fixedly mounted on the support plate 4612, and a guide groove 4625 formed on the arc-shaped plate 4624; the transmission rack 4621 is fixedly connected to the slide plate 452; the nozzle 44 is hingedly mounted on the U-shaped plate 4623; the guide groove 4625 is S-shaped, and the nozzle 44 is slidably mounted in the guide groove 4625.

[0090] When the spray angle of the nozzle 44 is adjusted, the second power source 453 is started to drive the slide plate 452 to move back and forth, which in turn drives the transmission rack 4621 to move back and forth. The transmission rack 4621 drives the transmission gear 4622 to rotate in both directions, which in turn drives the U-shaped plate 4623 to swing around the circumference of the transmission gear 4622. The U-shaped plate 4623 drives the nozzle 44 to swing, and at this time the horizontal spray angle of the nozzle 44 can be adjusted.

[0091] Since the nozzle 44 is slidably installed in the guide groove 4625, which is S-shaped, when the nozzle 44 moves along the guide groove 4625, the nozzle 44 deflects at the hinge point with the U-shaped plate 4623. As the nozzle 44 moves from the highest point to the lowest point of the guide groove 4625, the nozzle 44 achieves pitch swing, thereby adjusting the pitch spray angle of the nozzle 44.

[0092] By adjusting the height and angle of the nozzle 44, the spraying range of the nozzle 44 is expanded, ensuring that both the front and back of the leaves are covered, thereby improving the nutrient absorption efficiency and utilization effect.

[0093] It should be noted that nozzle 44 is preferably an atomizing nozzle; the uniform spraying of the atomizing nozzle further ensures that both the front and back of the leaves are covered, further improving the absorption efficiency and utilization of nutrients.

[0094] In this invention, when the conveying component 45 is started, it synchronously drives the angle adjustment unit 462 to operate. While realizing the automatic conveying of the mixed liquid and spraying it on the leaf surface, it drives the nozzle 44 to move horizontally and vertically, thereby expanding the spraying range of the nozzle 44. At the same time, in conjunction with the height adjustment unit 461, the spraying height of the nozzle 44 can be adjusted, further expanding the spraying range of the nozzle 44 and ensuring that both the front and back sides of the leaf are covered, thereby improving the nutrient absorption efficiency and utilization effect.

[0095] In this invention, the root fertilization mechanism 3 and the foliar fertilization mechanism 4 work together to deliver fertilizer into the soil for root fertilization of grapes, and also to spray foliar fertilizer on the grape leaves. This allows for two different fertilization modes for grapes, namely root fertilization and foliar fertilization, to meet the different fertilization needs of grapes.

[0096] It also includes: a stirring mechanism 5; the stirring mechanism 5 includes: a connecting rack 51 fixedly installed on the support plate 4612; a long shaft rotatably installed on the storage tank 31 and the liquid storage tank 41; a connecting gear 52 fixedly sleeved on the long shaft; a stirring plate 53 fixedly installed on the long shaft; the connecting rack 51 and the connecting gear 52 mesh with each other; the stirring plate 53 is located inside the storage tank 31.

[0097] When the power source 3 4611 is started, it drives the support plate 4612 to move up and down. The support plate 4612 drives the connecting rack 51 to move up and down. The connecting rack 51 drives the connecting gear 52 to rotate in both directions, which in turn drives the mixing plate 53 to rotate in both directions. This can stir and disperse the fertilizer in the storage box 31, preventing the fertilizer from clumping and affecting the feeding.

[0098] In this invention, the mixing mechanism 5 and the height adjustment unit 461 work together to adjust the spraying height of the nozzle 44 while mixing the fertilizer to prevent it from clumping and affecting the feeding process, thus preparing for subsequent fertilizer application.
