[0034] Reference Figure 1-Figure 10A peanut root system deep root fertilization device comprises a backpack storage box 1 and a grip tube 2, a T-shaped fixed tube 401 is slidably mounted on the inner wall of the grip tube 2 near the bottom, a baffle 4 is fixedly mounted on the lower surface of the T-shaped fixed tube 401, an insertion tube 3 is fixedly mounted on the lower surface of the baffle 4, a plurality of guide sleeves 10 are fixedly mounted on the inner wall of the insertion tube 3 in an aligned manner, an insertion syringe 11 is slidably mounted on the inner walls of the plurality of guide sleeves 10, a feeding tube 13 is fixedly mounted on the lower surface of the baffle 4, a plurality of discharge tubes 14 are fixedly mounted on the outer surface of the feeding tube 13 near the insertion syringe 11 in an aligned manner. A material receiving tube 15 is fixedly installed on the inner wall of the inserted syringe 11 near one end of the feeding barrel 13, the top of the material receiving tube 15 is abutted against the lower surface of the discharge tube 14, and a discharge port 1401 is provided on the lower surface of the discharge tube 14. The inserted syringe 11 is connected with the interior of the feeding barrel 13 through the material receiving tube 15, the discharge port 1401 and the discharge tube 14. A second limiting protrusion 1001 is provided on the inner wall of the guide sleeve 10, and a second limiting groove 1101 is provided on the circumferential outer surface of the inserted syringe 11. The second limiting protrusion 1001 is slidably installed with the inner wall of the second limiting groove 1101.

[0035] Pressing down the grip tube 2 causes the grip tube 2 to move downward relative to the insertion tube 3. The grip tube 2 drives the square pull rod 31 to move downward through the fixed rod 3101, and the downward movement of the square pull rod 31 drives multiple driving blocks on its outer surface to move downward. The driving blocks drive multiple insertion syringes 11 through the driving groove 32, the driving column 17 and the connecting plate 16. The guide sleeves 10 are extended from the top in sequence and inserted into soil layers of different depths, and then subsequent fertilization is carried out. Through this device, the roots of peanuts at different depths can be fertilized, so that the roots of peanuts can grow evenly, thereby ensuring the yield of peanuts.

[0036] In this embodiment, a support block 26 is fixedly installed on the lower surface of the discharge pipe 14 near the bottom end, and a square sliding column 27 is slidably inserted on the outer surface of the support block 26. The bottom end of the square sliding column 27 passes through the outer surface of the support block 26 and a limiting block is fixedly installed, and a sealing plate 28 is fixedly installed on the top of the square sliding column 27. The upper surface of the sealing plate 28 is abutted against the lower surface of the discharge pipe 14, and the discharge port 1401 is blocked by the sealing plate 28. The outer surface of the square sliding column 27 is sleeved with a third spring 29, and the third spring 29 is arranged between the sealing plate 28 and the support block 26. The end of the sealing plate 28 away from the support block 26 is abutted against the outer surface of the receiving pipe 15 near the top.

[0037] When the insertion syringe 11 extends and moves, it drives the receiving tube 15 to slide toward the guide sleeve 10, so that the feed port of the receiving tube 15 is connected with the discharge port 1401, which will cause the fertilizer particles in the uppermost section of the feeding barrel 13 to fall into the interior of the insertion syringe 11 through the receiving tube 15 for temporary storage, and then the fertilizer particles in the feeding barrel 13 enter the interior of the corresponding insertion syringe 11 one by one.

[0038] In this embodiment, a mounting sleeve 1102 is fixedly installed on the inner wall of the insertion syringe 11, and a square slide bar 18 is slidably installed on the inner wall of the mounting sleeve 1102. A sealing block 12 is fixedly installed on one end of the square slide bar 18. The sealing block 12 is slidably installed with the inner wall of the discharge end of the insertion syringe 11. Two stoppers 19 are symmetrically arranged on the outer surface of the square slide bar 18. The two stoppers 19 are arranged on both sides of the mounting sleeve 1102. The sliding distance of the square slide bar 18 is limited by the two stoppers 19. The other end of the square slide bar 18 penetrates the outer surface of the material receiving tube 15 and is slidably installed therewith. A fixing block 22 is fixedly installed on the other end of the square slide bar 18. A fixing groove is provided inside the fixing block 22. The fixing groove is relative to the fixing block 22. A block 23 is rotatably installed between the inner walls on both sides, and a torsion spring 24 is provided at the rotation installation fulcrums near the two ends of the block 23. An oblique angle is provided on the top of the block 23. The setting of the oblique angle makes the end of the block 23 sharp and easier to be inserted into the protrusion on the lower surface of the card plate 25. A plurality of card plates 25 are fixedly installed on the outer surface of the feeding barrel 13 near the material receiving pipe 15. A plurality of protrusions are provided on the lower surface of the card plate 25, and the top of the block 23 is abutted against the protrusion on the lower surface of the card plate 25. A limiting ring 20 is fixedly installed on the outer surface of the square slide bar 18 near the fixed block 22. A second spring 21 is sleeved on the outer surface of the square slide bar 18, and the second spring 21 is arranged between the limiting ring 20 and the material receiving pipe 15.

[0039] Under the action force of the first spring 8, the square pull rod 31 will reset upward. At this time, the insertion syringe 11 will slowly retract into the inside of the guide sleeve 10 in sequence. Since the insertion syringe 11 will drive the square slide bar 18 to move when it retracts, the square slide bar 18 will rub against the protrusion on the lower surface of the card plate 25 through the top of the card block 23, so that the card block 23 pushes the square slide bar 18 to move towards the soil direction. The square slide bar 18 will move to another block 19 and resist the mounting sleeve 1102. At this time, the sealing block 12 is pushed to the outside of the insertion syringe 11, and the discharge end of the insertion syringe 11 is opened. The fertilizer particles inside the insertion syringe 11 will slide into the hole where the insertion syringe 11 is inserted for storage. In the subsequent time, the fertilizer particles will slowly release their fertility to nourish the peanut root system. After the card block 23 moves to the position of the smooth surface of the end of the card plate 25, the sealing block 12 will seal the discharge end of the insertion syringe 11 again under the action force of the second spring 21.

[0040] In this embodiment, a square pull rod 31 is slidably inserted into the upper surface of the baffle 4, and the bottom end of the square pull rod 31 passes through the lower surface of the baffle 4. The outer surface of the square pull rod 31 on the side opposite to the material receiving tube 15 is aligned and fixed with multiple drive blocks, and the outer surfaces of the multiple drive blocks are penetrated with drive grooves 32. Two connecting plates 16 are symmetrically fixedly installed on the end of the syringe 11 inserted close to the material receiving tube 15, and a driving column 17 is fixedly installed between the two connecting plates 16. The driving column 17 is slidably installed on the inner wall of the driving groove 32. A fixing rod 3101 is fixedly installed on the inner wall of the grip tube 2, and the top end of the square pull rod 31 is fixedly installed on the outer surface of the fixing rod 3101. The circular outer surface of the T-shaped fixed tube 401 near the bottom is sleeved with a first spring 8, and the first spring 8 is arranged between the grip tube 2 and the baffle 4. A plurality of top columns 9 are equidistantly fixedly installed on the bottom end of the grip tube 2, and the drive groove 32 consists of a straight groove and an oblique groove.

[0041] The grip tube 2 drives the square pull rod 31 downward through the fixed rod 3101, and the downward movement of the square pull rod 31 drives multiple driving blocks on its outer surface to move downward. The driving blocks drive multiple insertion syringes 11 through the driving groove 32, the driving column 17 and the connecting plate 16, and the guide sleeves 10 are extended from the top in sequence and inserted into soil layers of different depths.

[0042] In this embodiment, the top end of the feeding cylinder 13 passes through the upper surface of the baffle 4 and is fixedly installed with a hose connector 30, the feeding end of the hose connector 30 is fixedly connected with a hose 6, and the outer surface of the backpack storage box 1 on one side close to the bottom end is fixedly installed with an electric discharge valve 5, the other end of the hose 6 passes through the top of the grip tube 2 and is fixedly connected with the discharge end of the electric discharge valve 5, a feeding port is provided at the top of the backpack storage box 1, and a momentary switch 7 is fixedly installed at the top of the grip tube 2.

[0043] In this embodiment, a plurality of first limiting protrusions 402 are equidistantly arranged on the circumferential outer surface of the T-shaped fixed tube 401 near the top end, and a first limiting groove 403 matching the plurality of first limiting protrusions 402 is opened on the inner wall of the grip tube 2 near the bottom end. The first limiting protrusion 402 is slidably installed on the inner wall of the first limiting groove 403, and the first limiting protrusion 402 and the first limiting groove 403 are cooperated to prevent the insertion tube 3 from rotating.

[0044] In this embodiment, the angle between the center line of the multiple guide sleeves 10 and the center line of the insert tube 3 is 60°, and the angle between the discharge pipe 14 and the feed tube 13 is 60°. The inclined setting of the discharge pipe 14 of the guide sleeve 10 allows the fertilizer particles to be discharged smoothly.

[0045] In this embodiment, through the setting of the torsion spring 24, the block 23 is erected and rotated toward the direction of the receiving tube 15, so that the top of the block 23 is always against the lower surface of the card plate 25, and the multiple protrusions on the lower surface of the card plate 25 are set in the middle position of the card plate 25 to ensure that the front and rear sections of the card plate 25 have a smooth area. The protrusions on the lower surface of the card plate 25 are set to increase the friction resistance between the top of the block 23 and the lower surface of the card plate 25. In actual use, a layer of rubber pad can be attached to the top of the block 23 to further increase the friction.

[0046] In this embodiment, it should be noted that in actual use, the setting of each driving groove 32 needs to meet the requirement that the inserted syringe 11 extends out of the guide sleeve 10 from top to bottom in sequence, and the straight groove and the oblique groove of the driving groove 32 can be set as shown in the figure.

[0047] It should be noted that when the present invention is used, the user adds solid granular fertilizer into the backpack storage box 1 from the feeding port at the top of the backpack storage box 1, and then the user carries the backpack storage box 1 on the back, and manually presses the inching switch 7, so that the electric signal emitted by the inching switch 7 controls the electric discharge valve 5, and a certain amount of solid granular fertilizer is transported from the backpack storage box 1 to the inside of the hose 6, and then enters the inside of the feeding tube 13 through the hose 6 and the hose connector 30 for temporary storage. The device can be used to quantitatively feed the feeding tube 13;

[0048] The user manually holds the top of the grip tube 2 and then inserts the insertion tube 3 into the soil layer where the peanut roots are located. Due to the setting of the first spring 8, there will be no relative sliding between the grip tube 2 and the insertion tube 3. When the lower surface of the baffle 4 contacts the upper surface of the soil layer, the grip tube 2 is continued to be pressed down. Due to the restriction of the baffle 4, the insertion tube 3 will not continue to sink, and the grip tube 2 will move downward relative to the insertion tube 3. The grip tube 2 drives the square pull rod 31 to move downward through the fixed rod 3101, and the downward movement of the square pull rod 31 drives multiple driving blocks on its outer surface to move downward. The driving blocks drive multiple insertion syringes 11 through the driving groove 32, the driving column 17 and the connecting plate 16. The guide sleeves 10 are extended from the top in sequence and inserted into soil layers of different depths, and then subsequent fertilization is carried out. The device can be used to fertilize the roots of peanuts at different depths, so that the roots of peanuts can grow evenly, thereby ensuring the yield of peanuts.

[0049] When the insertion syringe 11 extends and moves, it drives the receiving tube 15 to slide in the direction of the guide sleeve 10, so that the feed port of the receiving tube 15 is connected with the discharge port 1401. It should be noted that, through the arrangement of driving grooves 32 with different structures, multiple receiving tubes 15 can be connected with the discharge port 1401 from top to bottom. When the uppermost receiving tube 15 is connected with the discharge port 1401, the fertilizer particles in the uppermost section of the feeding tube 13 will fall into the interior of the insertion syringe 11 through the receiving tube 15 for temporary storage, and the fertilizer particles in the feeding tube 13 will enter the interior of the corresponding insertion syringe 11 one by one.

[0050] When discharging fertilizer particles, it is only necessary to stop pressing the grip tube 2. Under the action of the first spring 8, the square pull rod 31 will reset upward. At this time, the insertion syringe 11 will slowly retract into the inside of the guide sleeve 10 in sequence. Since the insertion syringe 11 will drive the square slide bar 18 to move when it retracts, the square slide bar 18 will rub against the protrusion on the lower surface of the card plate 25 through the top of the card block 23, so that the card block 23 pushes the square slide bar 18 to move toward the soil. The square slide bar 18 will move to another stopper 19 and abut against the installation sleeve 1102. At this time, the sealing block 12 is pushed to the outside of the insertion syringe 11, and the discharge end of the insertion syringe 11 is opened. The fertilizer particles inside the insertion syringe 11 will slide into the hole where the insertion syringe 11 is inserted for storage. In the subsequent period of time, the fertilizer particles will slowly release their fertility to nourish the peanut root system.

[0051] As the clamping block 23 moves to the position of the smooth surface at the end of the clamping plate 25, the sealing block 12 will re-seal the discharge end of the insertion syringe 11 under the action of the second spring 21. Repeating the above steps can continuously carry out deep root fertilization on the peanut root system. It should be noted that the user should not press down the grip tube 2 too fast so that the fertilizer particles can evenly fall into the interior of the insertion syringe 11.

[0052] The control method of the electrical components in this solution is controlled by an external controller matched therewith, and the control circuit can be realized by simple programming by technicians in this field. It belongs to the common knowledge in this field and is only used without improvement. In addition, the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and circuit connection in detail.

[0053] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
