Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to an injection fertilizing and pesticide applying device for preventing and controlling root diseases and insect pests of fruit trees. Background Art

[0002] In order to make fruit tree seedlings grow stronger, it is necessary to manually inject fertilizers and drugs into the roots of fruit trees to reduce the occurrence of diseases and insect pests. The traditional injection fertilizer and drug application device has a simple structure and mainly consists of three parts: a hose, a handle, a drain pipe, and a booster pump. The manufacturing cost is low.

[0003] However, in the actual injection process, firstly, the drainage holes on the outside of the drainage pipe are in a fixed state, and the root system of the fruit tree seedlings is relatively wide. During the injection process, it is necessary to manually adjust the drainage angle of the drainage holes, which is time-consuming and labor-intensive. In addition, before the injection operation, it is necessary to manually clean the injection ground and remove hard objects such as stones and branches on the ground to prevent the drainage pipe from colliding with hard objects during the injection process and causing damage to the drainage pipe. Moreover, after the injection is completed, it is necessary to manually clean the soil that may remain on the surface of the drainage pipe, which is very troublesome. Finally, after the injection is completed, it is often necessary to manually step on the injected ground to allow the liquid medicine to fully contact the fruit tree roots. The overall workload is large. Therefore, an injection fertilization and pesticide application device for the prevention and control of fruit tree root diseases and pests is provided. Summary of the Invention

In addition, when the injection of the liquid medicine is completed and the rotating drainage head is pulled out from the ground, when the cleaning inclined plate and the rotating drainage head are against each other, the rotating drainage head will be squeezed, forming a further processing operation for the sticky mud on the outside of the rotating drainage head, keeping the rotating drainage head clean for the next injection operation;

[0017] 4. Finally, after the injection of the liquid medicine is completed, the soil in the injection area will become wet. By beating and squeezing the extrusion plate, the stability of the soil can be maintained, which is more conducive to the growth of the roots of fruit tree seedlings.

DETAILED DESCRIPTION

[0028] See Figures 1-9 The hopper 5 is connected with the water inlet hose 2 at one end and the water inlet hose 3 at the other end of the hopper 5 is connected with the water inlet hose 2 at the other end of the hopper 5. The hopper 5 is connected with the water inlet hose 2 at the other end of the hopper 5. The hopper 5 is connected with the water inlet hose 2 at the other end of the hopper 5.

[0029] First, a power pump is fixedly installed on the upper side of the grip handle 1, and a switch for controlling the start of the power pump is installed on the side wall of the grip handle 1. Then, when it is necessary to perform fertilization and pesticide application operations, the water inlet hose 2 and the corresponding medicine tank or cartridge and other equipment are first connected. The staff holds the grip handle 1 and moves the device to the corresponding fertilization and pesticide application position, and steps on the foot pedal 6 with their feet. The foot pedal 6 drives the fixed block 4, the fixed transport pipe 3, the rotating drainage head 5 and the drill bit to move downward, so that the drill bit is inserted into the ground and near the roots of the fruit tree. The power pump is started by the switch to discharge the medicine liquid through the "water inlet hose 2-fixed transport pipe 3-rotating drainage head 5-drainage hole" method, so that the medicine liquid moves to the vicinity of the roots of the fruit tree, thereby completing the injection operation of the medicine liquid. After the injection is completed, the device is pulled out as a whole with force, thereby completing a medicine liquid injection operation. The above are all existing technologies and no unnecessary details are given.

[0030] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 , a control component for controlling the rotation of the rotating drainage head 5 is installed on the outside of the foot pedal 6, and the control component includes a rotating wheel 16 rotatably installed on the lower side of the foot pedal 6, and the lower side of the foot pedal 6 is rotatably connected to the first rotating rod 14, and the first rotating rod 14 is connected to the rotating wheel 16 through the pulley assembly 15, and the first rotating rod 14 is connected to the rotating drainage head 5 through the first gear 12 and the second gear 13. A power cylinder 8 is sleeved in the rotating wheel 16, and the lower side of the power cylinder 8 is fixedly connected to the fixed box 10, and a wave chute 20 is opened on the outside of the power cylinder 8, and a fixed protrusion 17 is slidably connected in the wave chute 20. The fixed protrusion 17 is fixedly connected to the rotating wheel 16, and the upper side of the power cylinder 8 is fixedly connected to the upper top plate 7, and the lower side of the fixed box 10 is fixedly connected to a plurality of conical protrusions 24, and the outer surface of each conical protrusion 24 is smoothly set;

[0031] First, before performing the injection operation, the fixed box 10 is placed on the ground and the conical protrusion 24 is inserted into the ground to complete a simple fixing operation of the fixed box 10. Then, during injection, especially when stepping on the foot pedal 6, the foot pedal 6 will move downward as a whole relative to the fixed box 10 and the power cylinder 8. During this process, under the action of the wave chute 20 and the fixed protrusion 17, the rotating wheel 16 will rotate back and forth relative to the foot pedal 6. The rotating wheel 16 drives the first rotating rod 14 to rotate back and forth through the pulley assembly 15. The first rotating rod 14 drives the rotating drainage head 5 to rotate back and forth through the first gear 12 and the second gear 13. As a result, during the injection process, the medicine discharged by the rotating drainage head 5 can quickly spread to the surroundings, thereby improving the injection effect.

[0032] like Figure 5 、 Figure 6 、 Figure 7 、 Figure 8, a cleaning assembly is installed on the outside of the fixed box 10, and the cleaning assembly includes two cleaning inclined plates 11. The side walls of the two cleaning inclined plates 11 are fixedly connected to the second rotating rod 34, and the outer side of the second rotating rod 34 is fixedly connected to the rotating ring 35. There are two third rotating rods 21 that are rotatably connected in the fixed box 10, and the outer sides of the two third rotating rods 21 are fixedly connected to the limiting plate 22. The rotating ring 35 and the third rotating rod 21 are rotatably connected, and a second torsion spring 33 is fixedly connected between the rotating ring 35 and the limiting plate 22. The outer side of the third rotating rod 21 is fixedly connected to the fixing ring 31, and the fixing ring 31 and the fixed box 10 are fixedly connected. A torsion spring 32, a clamping rod 30 is fixedly connected to the outside of the third rotating rod 21, a rack 27 is slidably connected to the fixed box 10, a moving rod 28 is fixedly connected to the outside of the rack 27, two clamping plates 29 are fixedly connected to the outside of the moving rod 28, a driven rod 25 is rotatably connected in the fixed box 10, and the driven rod 25 passes through the power cylinder 8 and is rotatably connected to the upper inner wall of the power cylinder 8, a third gear 26 is fixedly connected to the outside of the driven rod 25, the third gear 26 is meshed with the rack 27, a straight slide groove 9 is opened on the outside of the driven rod 25, a straight slide rod 18 is slidably connected in the straight slide groove 9, and the straight slide rod 18 is fixedly connected to the rotating wheel 16;

[0033] First, a through groove is opened on the outside of the power cylinder 8, and the straight slide rod 18 passes through the through groove. Secondly, during the rotation of the rotating wheel 16, the rotating wheel 16 drives the driven rod 25 to rotate back and forth through the straight slide groove 9 and the straight slide rod 18. The driven rod 25 drives the moving rod 28 to move back and forth through the third gear 26 and the rack 27. The clamping rod 30 is located between the two clamping plates 29 and is against one of the clamping plates 29. During the back and forth movement of the moving rod 28, the moving rod 28 drives the clamping rod 30 to rotate back and forth with the third rotating rod 21 as the center through the clamping plate 29. Figure 7 The third rotating rod 21 rotates counterclockwise when the moving rod 28 and the clamping rod 30 move to the left. The third rotating rod 21 rotates counterclockwise when the moving rod 28 and the clamping rod 30 move to the right. The rotating ring 35 drives the cleaning inclined plate 11 to rotate counterclockwise through the second rotating rod 34. Then the moving rod 28 and the clamping rod 30 start to move to the right, and finally the cleaning inclined plate 11 rotates clockwise. In the process of the rotating drainage head 5 being inserted into the ground, the cleaning inclined plate 11 rotates back and forth, and the cleaning inclined plate 11 and the ground are abutted, which can form a scraping motion on the ground in the area, similar to sweeping, to remove hard objects such as stones and branches on the ground, thereby reducing the possibility of damage to the rotating drainage head 5 caused by the hard objects on the upper side of the ground during the insertion of the rotating drainage head 5, thereby extending the service life of the rotating drainage head 5.

[0034] Moreover, when the injection of the liquid medicine is completed and the rotating drainage head 5 is pulled out from the ground, the rotating drainage head 5 will also rotate back and forth, which can shake off the mud that may be stuck to the outside of the rotating drainage head 5. Moreover, in this process, the cleaning inclined plate 11 will also rotate back and forth. When the cleaning inclined plate 11 and the rotating drainage head 5 collide with each other, an extrusion collision will be formed on the rotating drainage head 5, forming a further processing operation on the mud stuck to the outside of the rotating drainage head 5, keeping the rotating drainage head 5 clean for the next injection operation.

[0035] like Figure 9 , an extrusion assembly is installed on the outside of the cleaning inclined plate 11, and the extrusion assembly includes a plurality of oblique rods 41 fixedly installed in the cleaning inclined plate 11, and an oblique ring 42 is slidably connected to the outside of each oblique rod 41, and the lower side of the oblique ring 42 is slidably connected to the extrusion plate 23 through the connecting rod 19, and a stabilizing rod is fixedly connected between two adjacent oblique rings 42; the lower side of the rotating ring 35 is fixedly connected to the rotating cylinder 36, and the outer side of the rotating cylinder 36 is slidably connected to the moving ring 38, and an arc groove is opened on the outer side of the moving ring 38, and a control rod 43 is slidably connected in the arc groove, and the control rod 43 is fixedly connected to one of the oblique rings 42, and a straight spring 37 is fixedly connected between the moving ring 38 and the rotating ring 35, and a plurality of triangular blocks 39 are fixedly connected to the outer side of the moving ring 38, and two round head rods 40 are fixedly connected to the outside of the fixed box 10, and a buffer spring is fixedly connected between the connecting rod 19 and the extrusion plate 23, and the extrusion plate 23 is arranged for an inclination;

[0036] First, during the back and forth rotation of the cleaning inclined plate 11, since the moving ring 38 and the rotating cylinder 36 are connected for up and down sliding, the moving ring 38 and the triangular block 39 will rotate with the rotating ring 35. During this process, when the triangular block 39 and the round head rod 40 abut against each other, the moving ring 38 will move upward relative to the rotating ring 35 under the obstruction of the round head rod 40, and the straight spring 37 will be deformed until the lower end of the round head rod 40 and the triangular block 39 abut against each other. At this time, the moving ring 38 continues to rotate with the rotating cylinder 36. Under the action of 37, the movable ring 38 will move downward relative to the rotating ring 35, causing the movable ring 38 to move up and down relative to the rotating ring 35 during this process. The movable ring 38 drives the oblique ring 42 to move through the control rod 43, and the oblique ring 42 drives the extrusion plate 23 to move up and down through the connecting rod 19. The extrusion plate 23 can form a knocking and squeezing effect on the ground. After the injection of the liquid medicine is completed, the soil in the injection area will become wet. The knocking and squeezing of the extrusion plate 23 can maintain the stability of the soil, which is more convenient for the growth of the roots of fruit trees.

[0037] In the present invention, when it is necessary to carry out fertilization and pesticide application operations, the water inlet hose 2 is first connected to the corresponding medicine tank or cartridge and other equipment, the staff holds the handle 1 to move the device to the corresponding fertilization and pesticide application position, and steps on the foot pedal 6 with the foot. The foot pedal 6 drives the fixed block 4, the fixed transport pipe 3, the rotating drainage head 5 and the drill bit to move downward, so that the drill bit is inserted into the ground and near the root system of the fruit tree. The power pump is started by the switch to discharge the medicine liquid through the "water inlet hose 2-fixed transport pipe 3-rotating drainage head 5-drainage hole" method, so that the medicine liquid moves to the vicinity of the root system of the fruit tree, thereby completing the injection operation of the medicine liquid. After the injection is completed, the device is pulled out as a whole with force, thereby completing a medicine liquid injection operation. The above are all existing technologies and no redundant description is made.

[0038] Before performing the injection operation, the fixed box 10 is first placed on the ground, and the conical protrusion 24 is inserted into the ground to complete a simple fixing operation of the fixed box 10. Then, during the injection, especially when the foot pedal 6 is stepped on, the foot pedal 6 will move downward relative to the fixed box 10 and the power cylinder 8 as a whole. During this process, under the action of the wave chute 20 and the fixed protrusion 17, the rotating wheel 16 will rotate back and forth relative to the foot pedal 6. The rotating wheel 16 drives the first rotating rod 14 to rotate back and forth through the pulley assembly 15. The first rotating rod 14 drives the rotating drainage head 5 to rotate back and forth through the first gear 12 and the second gear 13. As a result, during the injection process, the liquid medicine discharged by the rotating drainage head 5 can quickly spread to the surroundings, thereby improving the injection effect.

[0039] The third rotating rod 21 rotates counterclockwise when the third rotating rod 21 drives the lower rotating ring 35 to rotate counterclockwise through the second torsion spring 33. The rotating ring 35 drives the cleaning inclined plate 11 to rotate counterclockwise through the second rotating rod 34. Then the moving rod 28 and the clamping rod 30 start to move rightward, and finally the cleaning inclined plate 11 rotates clockwise. In the process of the rotating drainage head 5 being inserted into the ground, the cleaning inclined plate 11 rotates back and forth. The cleaning inclined plate 11 and the ground are in contact with each other, which can form a scraping motion on the ground in the area, similar to sweeping, to remove hard objects such as stones and branches on the ground, thereby reducing the possibility of the rotating drainage head 5 being damaged by the hard objects on the upper side of the ground during the process of the rotating drainage head 5 being inserted into the ground, thereby extending the service life of the rotating drainage head 5.

[0040] Moreover, when the injection of the liquid medicine is completed and the rotary drainage head 5 is pulled out from the ground, the rotary drainage head 5 will also rotate back and forth, which can shake off the mud that may be stuck on the outside of the rotary drainage head 5. Moreover, during this process, the cleaning inclined plate 11 will also rotate back and forth. When the cleaning inclined plate 11 and the rotary drainage head 5 collide with each other, an extrusion collision will be formed on the rotary drainage head 5, thereby further processing the mud stuck on the outside of the rotary drainage head 5 and keeping the rotary drainage head 5 clean for the next injection operation.

[0041] During the back and forth rotation of the cleaning inclined plate 11, since the moving ring 38 and the rotating cylinder 36 are connected for up and down sliding, the moving ring 38 and the triangular block 39 will rotate with the rotating ring 35. During this process, when the triangular block 39 and the round head rod 40 abut against each other, the moving ring 38 will move upward relative to the rotating ring 35 under the obstruction of the round head rod 40, and the straight spring 37 will be deformed until the lower end of the round head rod 40 and the triangular block 39 abut against each other. At this time, the moving ring 38 continues to rotate with the rotating cylinder 36. 7, the movable ring 38 will move downward relative to the rotating ring 35, causing the movable ring 38 to move up and down relative to the rotating ring 35 during this process. The movable ring 38 drives the oblique ring 42 to move through the control rod 43, and the oblique ring 42 drives the extrusion plate 23 to move up and down through the connecting rod 19. The extrusion plate 23 can form a knocking and squeezing effect on the ground. After the injection of the liquid medicine is completed, the soil in the injection area will become wet. The knocking and squeezing of the extrusion plate 23 can maintain the stability of the soil, which is more convenient for the growth of the root system of the fruit tree.
