Description

Technical Field

[0001] This invention relates to the field of fruit tree fertilization technology, and in particular to a fertilization machine for weeding the ground around fruit trees. Background Technology

[0002] During the planting process, weeding and fertilizing around the fruit trees are very important agricultural management measures, which can promote the healthy growth of the fruit trees and increase yield and fruit quality.

[0003] Patent CN112586121B discloses a fertilizer applicator for weeding the ground around fruit trees. The applicator includes a vehicle body with an upward-opening fertilizer chamber on its upper surface and a downward-opening braking chamber on its lower inner wall. This invention is simple in structure and easy to operate. When fertilizing the soil around fruit trees, a fixing mechanism automatically restricts the device from the fruit trees, and the fertilizing mechanism punches holes in the soil around the trees to apply fertilizer, achieving the effect of applying fertilizer into the ground without damaging the tree roots. During operation, the device continuously removes weeds. After fertilizing the area around the fruit trees, the fixing mechanism can be released to stop fertilization, thus achieving weeding only around the fruit trees without spilling fertilizer. However, this fertilizer applicator achieves weeding by cutting the weeds with a rotating weeding wheel, failing to pull the weed roots out of the soil, resulting in poor weeding effectiveness.

[0004] To address the aforementioned issues, we propose a fertilizer applicator for weeding the ground around fruit trees. This applicator can pull impurities out of the soil along with their roots during fertilization, thus improving the weeding effect. Summary of the Invention

[0005] In order to overcome the shortcomings of existing weeding and fertilizing machines that can only cut weeds but cannot pull the roots out of the soil, this invention provides a fertilizing machine for weeding the ground around fruit trees.

[0006] A fertilizer applicator for weeding the ground around fruit trees includes a frame, a mounting frame fixedly connected to the frame, a pusher plate fixedly connected between the mounting frame and the frame, a transversely symmetrical motor fixedly connected to the side of the pusher plate near the mounting frame, the output shaft of the motor being rotatably connected to the mounting frame, and a weeding roller fixedly connected to the output shaft of the motor. The weeding roller has equidistantly distributed protrusions, which interlock and mesh. A sprayer is fixedly connected inside the weeding roller. The frame is equipped with a soil loosening component for loosening the soil, and the soil loosening component is equipped with a fertilizer applicator for fertilizing.

[0007] To further explain, the soil loosening component includes a mounting ring, which is fixedly connected to the frame. The mounting ring is slidably connected to transversely symmetrical soil loosening plates, and an arc-shaped rack is fixedly connected to the soil loosening plates. The mounting frame is rotatably connected to transversely symmetrical gear-deficient shafts, which mesh with adjacent arc-shaped racks. A pulley assembly is connected between the gear-deficient shaft and the adjacent motor output shaft. A transversely symmetrical telescopic rod is fixedly connected to the mounting ring. The telescopic end of the telescopic rod is fixedly connected to the adjacent soil loosening plate, and a first spring is connected between the telescopic end and the fixed end of the telescopic rod.

[0008] To further explain, the fertilization assembly includes a pusher frame, which is fixedly connected to a loosening plate. A transversely symmetrical connecting plate is fixedly connected to the mounting ring. A connecting pipe is rotatably connected to the connecting plate. One end of the connecting pipe is rotatably connected to an adjacent sprayer. The pusher frame and the adjacent connecting pipe are press-fitted together. The other end of the connecting pipe is connected to a fertilizer box. A baffle is slidably connected inside the fertilizer box. A guide rod is fixedly connected to the fertilizer box. The baffle is slidably connected to the adjacent guide rod. A second spring is connected between the baffle and the adjacent guide rod. A first torsion spring is connected between the connecting pipe and the adjacent connecting plate.

[0009] To further explain, the baffle is equipped with extrusion protrusions that extend beyond the fertilizer box.

[0010] Further explanation: It also includes a discharge component for conveying the pulled weeds to the side. The discharge component is set on the mounting frame and includes a fan. The fan is fixedly connected to the top of the mounting frame and a flexible hose is connected to the fan. A fixing plate is fixedly connected to the top of the mounting ring. A guide plate is fixedly connected to the fixing plate. An air outlet frame is fixedly connected to the side of the guide plate near the fan and is connected to the end of the flexible hose.

[0011] Further explanation: It also includes an adjustment component for adjusting the angle of weed discharge. The adjustment component is set on the guide plate and includes an adjustment plate. The adjustment plate is rotatably connected to the side of the guide plate away from the air outlet frame. An arc-shaped plate is fixedly connected to the guide plate. A fixing block is fixedly connected to the adjustment plate. A locking rod is slidably connected to the fixing block. A third spring is connected between the locking rod and the fixing block. A second torsion spring with front and rear symmetry is connected between the adjustment plate and the guide plate.

[0012] To further explain, the curved plate has equally spaced slots, and the locking rods are inserted into adjacent slots.

[0013] Further explanation: It also includes a soil removal component for clearing soil from the roots of weeds. The soil removal component is set on the mounting frame and the pusher plate. The soil removal component includes a horizontally symmetrical mudguard. The horizontally symmetrical mudguard is slidably connected between the mounting frame and the pusher plate. An electric push rod is fixedly connected to the pusher plate. The telescopic end of the electric push rod is fixedly connected to a squeezing frame. A fourth spring is connected between the mudguard and the pusher plate.

[0014] To further explain, the mudguard has a toothed comb structure.

[0015] To further explain, the side of the extrusion frame closest to the mudguard has a laterally symmetrical inclined structure, and the extrusion frame and the inclined surface are in extrusion fit with the mudguard.

[0016] The present invention has the following advantages: 1. When the two weeding rollers rotate outward, the weeds located between the two weeding rollers will be clamped by the convex plates on the weeding rollers and pulled upward, thereby pulling the weeds out of the soil with their roots. When weeding, the sprayer can supply fertilizer in the weeding rollers into the fertilizer box, and the fertilizer box will sprinkle fertilizer under the two weeding rollers for fertilization. When the loosening plate slides up and down, it can clear the soil around the fruit trees.

[0017] 2. When the fan operates, it blows air downwards through the hose and air outlet frame. The weeds discharged by the rotating weed roller will be discharged to the right along the guide plate under the action of the wind.

[0018] 3. When the weeds are discharged to the right along the guide plate, they will also move along the direction of the adjustment plate. By controlling the up and down rotation of the adjustment plate to adjust the angle, the weeds can be discharged to the designated position along the tilt direction of the adjustment plate.

[0019] 4. The mudguards move in and out continuously to beat and squeeze the weeds, thereby breaking up the soil at the base of the mudguards and preventing sand and gravel from damaging the weeding rollers. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0034] Example 1: A fertilizer applicator for weeding the ground around fruit trees, such as... Figures 1-7 As shown, the device includes a frame 1, a mounting frame 2, a pusher plate 3, a motor 4, a weeding roller 5, a sprayer 6, a soil loosening component, and a fertilizer application component. The mounting frame 2 is fixedly connected to the front of the frame 1. The pusher plate 3 is fixedly connected to the rear of the mounting frame 2 and the frame 1. The lower part of the pusher plate 3 is fixedly connected to the left and right symmetrical motors 4. The output shaft of the motor 4 is rotatably connected to the mounting frame 2. The weeding roller 5 is fixedly connected to the output shaft of the motor 4. The weeding roller 5 is provided with equidistantly distributed protrusions. The protrusions on the left and right weeding rollers 5 are interlocked. The sprayer 6 is fixedly connected inside the weeding roller 5. The frame 1 is provided with a soil loosening component for loosening the soil. The soil loosening component is provided with a fertilizer application component for fertilizing.

[0035] When using the device, the operator pushes the trolley plate 3, which moves the device to a suitable position via the frame 1. Then, the operator starts the motor 4. The output shaft of the motor 4 rotates, causing the two weeding rollers 5 on the left and right to rotate outward. The weeds located between the two weeding rollers 5 are clamped by the convex plates on the weeding rollers 5 and pulled upward, thus pulling the weeds out of the soil by the roots. During weeding, the sprayer 6 can supply fertilizer from the weeding rollers 5 into the fertilization component for fertilization, while the soil loosening component can loosen the soil. After weeding and fertilization are completed, the operator turns off the motor 4.

[0036] Example 2: Based on Example 1, such as Figure 1 , Figure 3 and Figure 4 As shown, the soil loosening assembly includes a mounting ring 7, a soil loosening plate 8, an arc-shaped rack 9, a gear-less shaft 10, a pulley assembly 11, a telescopic rod 12, and a first spring 13. The mounting ring 7 is fixedly connected to the front of the frame 1. The soil loosening plate 8 is slidably connected to both sides of the mounting ring 7. The arc-shaped rack 9 is fixedly connected to the rear side of the soil loosening plate 8. The gear-less shaft 10 is rotatably connected to both sides of the mounting frame 2. The gear-less shaft 10 meshes with the adjacent arc-shaped rack 9. The gear-less shaft 10 is connected to the adjacent output shaft of the motor 4 via a pulley assembly 11. The pulley assembly 11 consists of two pulleys and a flat belt. One pulley is fixedly connected to the output shaft of the motor 4, and another pulley is fixedly connected to the gear-less shaft 10. A flat belt is fitted between the two pulleys. The telescopic rod 12 is fixedly connected to both sides of the mounting ring 7. The telescopic end of the telescopic rod 12 is fixedly connected to the adjacent soil loosening plate 8. The first spring 13 is connected between the telescopic end and the fixed end of the telescopic rod 12.

[0037] By setting up a soil loosening component, the soil around the fruit trees can be cleared. The specific operation is as follows: When the output shaft of motor 4 rotates, it drives the gearless shaft 10 to rotate through the pulley group 11. The rotation of the gearless shaft 10 drives the arc rack 9 to move downward. The downward movement of the arc rack 9 causes the soil loosening plate 8 to slide downward in an arc. The downward sliding of the soil loosening plate 8 causes the telescopic rod 12 to shorten, and the first spring 13 to deform. When the gearless shaft 10 rotates to disengage from the arc rack 9, under the action of the first spring 13, the telescopic rod 12 extends and drives the soil loosening plate 8 to slide upward and reset. When the gearless shaft 10 rotates to re-engage with the arc rack 9, the above actions are repeated, so that the soil loosening plate 8 can move up and down continuously. When the soil loosening plate 8 slides up and down, it can clear the soil around the fruit trees.

[0038] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the fertilization assembly includes a pusher frame 14, a connecting plate 15, a connecting pipe 16, a fertilizer box 17, a baffle 18, a guide rod 19, a second spring 20, and a first torsion spring 21. The pusher frame 14 is fixedly connected to the front inner side of the loosening plate 8. The upper front side of the mounting ring 7 is fixedly connected to the left and right symmetrical connecting plates 15. The front of the connecting plate 15 is rotatably connected to the connecting pipe 16. The upper end of the connecting pipe 16 is rotatably connected to the front end of the adjacent sprayer 6. The pusher frame 14 and the adjacent connecting pipe 16 are in a pressing fit. The lower end of the connecting pipe 16 is connected to the fertilizer box 17. The baffle 18 is slidably connected inside the fertilizer box 17. The front of the baffle 18 is provided with a pressing protrusion extending out of the fertilizer box 17. The guide rod 19 is fixedly connected to the middle of the fertilizer box 17. The baffle 18 is slidably connected to the adjacent guide rod 19. The second spring 20 is connected between the baffle 18 and the adjacent guide rod 19. The first torsion spring 21 is connected between the connecting pipe 16 and the adjacent connecting plate 15.

[0039] By setting up a fertilization assembly, fertilizer can be spread onto the soil. The specific operation is as follows: The sprayer 6 draws fertilizer from the weeding roller 5 and directs it into the connecting pipe 16, which in turn directs it into the fertilizer box 17. At this time, the fertilizer is positioned above the baffle 18. When the loosening plate 8 slides downwards, the pusher 14 also moves downwards. The downward movement of the pusher 14 pushes the connecting pipe 16 to rotate inwards, causing the first torsion spring 21 to deform. The inward rotation of the connecting pipe 16 drives the fertilizer box 17 and the baffle 18 to move inwards. When the pressing protrusions on the left and right baffles 18 move inwards until they contact each other, the fertilizer box 17 continues to move inwards. The movement will cause the baffle 18 to slide, so that the baffle 18 no longer blocks the inside of the fertilizer box 17. The second spring 20 will deform, and the fertilizer in the fertilizer box 17 will fall out from the bottom. Since the fertilizer box 17 is located in the middle of the device at this time, the fallen fertilizer is also located below the two weeding rollers 5 on the left and right. When the loosening plate 8 slides upward and drives the push frame 14 to move upward, under the action of the first torsion spring 21 resetting, the connecting pipe 16 will drive the fertilizer box 17 to move outward and reset. Under the action of the second spring 20 resetting, the fertilizer box 17 moves outward and causes the baffle 18 to reset and block the fertilizer again.

[0040] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a discharge assembly for conveying the pulled weeds to the side. The discharge assembly includes a blower 22, a hose 23, an air outlet frame 24, a fixing plate 25, and a guide plate 26. The blower 22 is fixedly connected to the upper middle part of the mounting frame 2, and the hose 23 is connected to the blower 22. The fixing plate 25 is fixedly connected to the upper side of the mounting ring 7, and the guide plate 26 is fixedly connected to the fixing plate 25. The air outlet frame 24 is fixedly connected to the left side of the guide plate 26, and the air outlet frame 24 is connected to the tail end of the hose 23.

[0041] By setting up the discharge component, the pulled weeds can be discharged to the side. The specific operation is as follows: The operator starts the blower 22. The blower 22 blows air down the guide plate 26 through the hose 23 and the air outlet frame 24. The weeds discharged by the rotating weed roller 5 will be discharged to the right along the guide plate 26 under the action of the wind. When the device is finished, the operator turns off the blower 22.

[0042] like Figure 1 and Figure 10 As shown, it also includes an adjustment assembly for adjusting the weed discharge angle. The adjustment assembly includes an adjustment plate 27, an arc plate 28, a fixing block 29, a locking rod 30, a third spring 31, and a second torsion spring 32. The right side of the guide plate 26 is rotatably connected to the adjustment plate 27, the right rear side of the guide plate 26 is fixedly connected to the arc plate 28, the left rear side of the adjustment plate 27 is fixedly connected to the fixing block 29, the locking rod 30 is slidably connected to the fixing block 29, the arc plate 28 has equally spaced slots, the locking rod 30 is inserted into the adjacent slots, the locking rod 30 is connected to the fixing block 29 by the third spring 31, and the adjustment plate 27 and the guide plate 26 are connected by symmetrical second torsion springs 32.

[0043] The angle and position of the weed discharge can be adjusted by setting the adjustment component. The specific operation is as follows: When the weeds are discharged to the right along the guide plate 26, they will also move along the direction of the adjustment plate 27. When it is necessary to adjust the position of the weed discharge, the operator pulls the locking rod 30 to slide backward. The third spring 31 deforms, and the locking rod 30 no longer locks the arc plate 28 after sliding backward. At this time, the operator can control the adjustment plate 27 to rotate up and down to adjust the angle. After the adjustment plate 27 is adjusted, the operator releases the locking rod 30. Under the action of the third spring 31 resetting, the locking rod 30 slides forward and resets to lock into the slot of the arc plate 28, thereby fixing the angle of the adjustment plate 27. After the adjustment plate 27 is adjusted, the weeds will be discharged to the designated position along the tilt direction of the adjustment plate 27.

[0044] like Figure 1 , Figure 11 and Figure 12 As shown, it also includes a soil removal component for clearing soil from the roots of weeds. The soil removal component includes a mudguard 33, an electric push rod 34, a squeezing frame 35, and a fourth spring 36. The mudguard 33 is slidably connected between the mounting frame 2 and the trolley plate 3. The front of the mudguard 33 has a toothed comb structure. The electric push rod 34 is fixedly connected to the lower part of the trolley plate 3. The extension end of the electric push rod 34 is fixedly connected to the squeezing frame 35. The lower part of the squeezing frame 35 has a left-right symmetrical inclined structure. The squeezing frame 35 and the inclined surface squeeze and cooperate with the mudguard 33. The fourth spring 36 is connected between the mudguard 33 and the trolley plate 3.

[0045] By setting up a soil-removing component, the soil at the roots of weeds can be broken up. The specific operation is as follows: The operator controls the extension and retraction of the electric push rod 34 to drive the squeezing frame 35 to move up and down. When the squeezing frame 35 moves upward, it squeezes the two mudguards 33 on the left and right sides to slide inward, and the fourth spring 36 deforms. When the squeezing frame 35 slides downward, the mudguards 33 slide outward and reset under the action of the fourth spring 36. The up and down movement of the squeezing frame 35 can drive the mudguards 33 to move inward and outward continuously. The mudguards 33 beat and squeeze the weeds, thereby breaking up the soil at the roots of the mudguards 33 and preventing sand and gravel from being mixed in with the soil and damaging the weeding roller 5.

[0046] It should be understood that the above description is for illustrative purposes only and is not intended to limit the invention. Those skilled in the art will understand that variations of the invention are included within the scope of the claims herein.
