Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer applicator technology, and in particular to a root-directed fertilizer applicator for agricultural planting. Background Technology
[0002] In agricultural planting, in order to apply fertilizer to plant roots in a targeted manner, there is a type of liquid fertilizer gun on the market. It can draw liquid fertilizer through a pump connected to a pipe, and then insert the perforated gun into the soil near the plant roots for fertilization. The liquid fertilizer gun used in agricultural planting is a lightweight agricultural tool specially designed to accurately inject liquid fertilizer (such as dissolved chemical fertilizer solution, organic fertilizer liquid, water-fertilizer mixture, etc.) into the soil root area. Its core function is to replace traditional spreading with "targeted injection" to achieve efficient delivery of liquid nutrients. It is especially suitable for fruit trees, vegetables, cash crops and other scenarios with high requirements for fertilization precision.
[0003] When existing fertilizer guns are inserted into the soil where plant roots are located, mud and sand easily enter through the perforated nozzle. With prolonged use, soil and fertilizer residue tend to adhere to the inside of the nozzle, which can easily clog the fertilizer holes. To address this, we propose a root-directed fertilizer applicator for agricultural planting. Utility Model Content
[0004] The main purpose of this invention is to provide a root-directed fertilizer applicator for agricultural planting. It features a sleeve mechanism at the nozzle tube of the fertilizer gun body. The conical tube of the sleeve mechanism can be fitted over the outside of the nozzle tube, forming an outer protective structure with an L-shaped fixing block and a double-mouth liquid bladder block. The nozzle tube can be inserted into the soil near the roots using the conical tube. As the double-mouth liquid bladder block is opened under pressure, the fertilizer solution discharged from the nozzle tube can flow along the double-mouth liquid bladder block towards the plant roots for targeted fertilization. This effectively avoids the problem of mud and sand entering the nozzle tube and condensing with the fertilizer solution, thus effectively solving the problems in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A root-directed fertilizer applicator for agricultural planting includes a fertilizer gun body and a nozzle tube. The nozzle tube is fixedly connected to the tube body of the fertilizer gun body. It also includes a fitting mechanism, which comprises a conical cylinder, an L-shaped fixing block, a double-mouth liquid bladder block, a T-shaped main half-tube, a T-shaped secondary half-tube, a pedal, and a rotating support ring. The conical cylinder is fitted onto the outer side of the nozzle tube. The conical cylinder has annularly distributed outlets near its own conical tip on its straight tube body for mounting the L-shaped fixing block and the double-mouth liquid bladder block. The L-shaped fixing block... A rectangular block is formed by bonding the concave surface of the double-hole liquid bladder block, and an L-shaped fixing block is locked to the outer tube wall of the nozzle tube by bolts. A T-shaped main half-tube and a T-shaped auxiliary half-tube are screwed onto the nozzle opening and fitted onto the outside of the nozzle tube. The outer sides of the large tubes of the T-shaped main half-tube and the T-shaped auxiliary half-tube are respectively fixed with main hole blocks and auxiliary hole blocks for screwing bolts. A swivel ring is screwed onto the outside of the nozzle tube inside the T-shaped main half-tube and the T-shaped auxiliary half-tube. A foot pedal is welded to the back of the T-shaped auxiliary half-tube and the auxiliary hole block.
[0007] Furthermore, the surface of the secondary hole block is recessed with an L-shaped groove for mounting the L-shaped interlocking ribs, and the L-shaped interlocking ribs are symmetrically fixed on the surface of the main hole block.
[0008] By adopting the above technical solution, the main hole block can be positioned and locked in the L-shaped groove of the auxiliary hole block by inserting the L-shaped interlocking rib, ensuring the assembly firmness after the main hole block and the auxiliary hole block are connected.
[0009] Furthermore, the T-shaped main half-pipe and the T-shaped auxiliary half-pipe are joined together to form a T-shaped threaded pipe, and a spring fitted inside the T-shaped threaded pipe is fitted on the outside of the gun head tube. The spring is fitted between the swivel support ring and the top cavity of the T-shaped threaded pipe, and the inner diameter of the straight pipe body of the T-shaped threaded pipe is larger than that of the swivel support ring, and the diameter of the top cavity of the T-shaped threaded pipe is smaller than the diameter of the spring coil.
[0010] By adopting the above technical solution, the T-shaped threaded tube composed of the T-shaped main half tube and the T-shaped auxiliary half tube can be screwed into the conical cylinder. Subsequently, a spring can be inserted into the T-shaped threaded tube to form an elastic support between the T-shaped threaded tube and the swivel ring.
[0011] Furthermore, the large liquid port of the dual-port liquid bladder block faces the nozzle tube, and the small liquid port of the dual-port liquid bladder block faces the outside of the cone-shaped cylinder.
[0012] By adopting the above technical solution, the liquid fertilizer discharged from the nozzle can pass through the large liquid outlet of the double-mouth liquid sac block, then be discharged from the small liquid outlet to supply the plant roots.
[0013] Furthermore, a rectangular groove is recessed in the outer wall of the nozzle tube for mounting the double-hole liquid bladder block and the L-shaped fixing block, and an installation hole for screwing bolts is opened between the block of the L-shaped fixing block and the tube body of the nozzle tube. An enlarged hole for accommodating bolt heads is opened on the outside of the installation hole of the L-shaped fixing block.
[0014] By adopting the above technical solution, after the double-hole liquid bladder block and the L-shaped fixed block are bonded and assembled into a rectangular block, they can be snapped into the rectangular groove of the gun head tube. Then, an internal hex bolt can be screwed into the L-shaped fixed block and the gun head tube to lock them. At the same time, the head of the internal hex bolt can be hidden in the enlarged hole of the L-shaped fixed block.
[0015] Furthermore, the gun head tube has a threaded outer tube wall on the outside of the tube body near the T-shaped main half tube, and a swivel ring is screwed onto the threaded outer tube wall of the gun head tube.
[0016] By adopting the above technical solution, the gun head tube can be fitted with a swivel support ring for screw-on installation using a threaded tube wall.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This utility model features a sleeve mechanism installed at the nozzle of the fertilizer gun body. The conical tube of the sleeve mechanism can be sleeved on the outside of the nozzle tube, forming an outer protective structure with an L-shaped fixing block and a double-mouth liquid bladder block. The nozzle tube can be inserted into the soil near the root system with the help of the conical tube. As the double-mouth liquid bladder block is opened under pressure, the fertilizer solution discharged from the nozzle tube can be directed to the plant roots along the double-mouth liquid bladder block for targeted fertilization, effectively avoiding the problem of mud and sand entering the nozzle tube and condensing with the fertilizer solution, causing blockage.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figure 1-4 As shown, an agricultural root-directed fertilizer applicator includes a fertilizer gun body 1 and a nozzle tube 2. The nozzle tube 2 is fixedly connected to the tube body of the fertilizer gun body 1. It also includes a fitting mechanism 3, which comprises a conical cylinder 4, an L-shaped fixing block 6, a double-mouth liquid bladder block 7, a T-shaped main half-tube 8, a T-shaped secondary half-tube 9, a pedal 14, and a rotating support ring 16. The conical cylinder 4 is fitted onto the outer side of the nozzle tube 2. The conical cylinder 4 has annularly distributed outlets 5 near its own conical tip on its straight tube body for mounting the L-shaped fixing block 6 and the double-mouth liquid bladder block 7. The L-shaped fixing block... The L-shaped block 6 is bonded to the concave surface of the double-mouth liquid bladder block 7 to form a rectangular block, and the L-shaped fixing block 6 is locked to the outer tube wall of the gun head tube 2 by bolts. The conical tube 4 is screwed to the opening of the tube and a T-shaped main half tube 8 and a T-shaped auxiliary half tube 9 are fitted on the outside of the gun head tube 2. The outer sides of the large tubes of the T-shaped main half tube 8 and the T-shaped auxiliary half tube 9 are respectively fixed with a main hole block 10 and an auxiliary hole block 11 for screwing bolts. A swivel ring 16 is screwed to the outside of the gun head tube 2 inside the T-shaped main half tube 8 and the T-shaped auxiliary half tube 9. A foot pedal 14 is welded to the back of the T-shaped auxiliary half tube 9 and the auxiliary hole block 11.
[0027] The auxiliary hole block 11 has an L-shaped groove 13 for mounting the L-shaped interlocking rib 12 on its surface, and the L-shaped interlocking rib 12 is symmetrically fixed on the surface of the main hole block 10.
[0028] By adopting the above technical solution, the main hole block 10 can be inserted into the L-shaped groove 13 of the auxiliary hole block 11 for positioning and locking, ensuring the assembly firmness of the main hole block 10 and the auxiliary hole block 11 after docking.
[0029] The T-shaped main half-tube 8 and the T-shaped auxiliary half-tube 9 are joined together to form a T-shaped threaded tube, and a spring 15 is inserted inside the T-shaped threaded tube and sleeved on the outside of the gun head tube 2. The spring 15 is inserted between the swivel ring 16 and the top cavity of the T-shaped threaded tube, and the inner diameter of the straight tube of the T-shaped threaded tube is larger than the ring body of the swivel ring 16, and the diameter of the top cavity of the T-shaped threaded tube is smaller than the diameter of the spring ring of the spring 15.
[0030] By adopting the above technical solution, the T-shaped threaded tube composed of the T-shaped main half tube 8 and the T-shaped secondary half tube 9 can be screwed into the conical cylinder 4. Then, a spring 15 can be inserted into the T-shaped threaded tube to form an elastic support between the T-shaped threaded tube and the swivel ring 16.
[0031] The large liquid port of the dual-port liquid bladder block 7 faces the nozzle tube 2, and the small liquid port of the dual-port liquid bladder block 7 faces the outside of the cone tube 4.
[0032] By adopting the above technical solution, the liquid fertilizer discharged from the nozzle tube 2 can pass through the large liquid outlet of the double-mouth liquid bag block 7, then be discharged from the small liquid outlet to supply the plant roots.
[0033] The outer wall of the gun head tube 2 is recessed with a rectangular groove for mounting the double-mouth liquid bladder block 7 and the L-shaped fixing block 6. The L-shaped fixing block 6 and the tube body of the gun head tube 2 are provided with a mounting hole for screwing bolts. The mounting hole of the L-shaped fixing block 6 is enlarged on the outside to accommodate the bolt head.
[0034] By adopting the above technical solution, after the double-hole liquid bladder block 7 and the L-shaped fixing block 6 are bonded and assembled into a rectangular block, they can be snapped into the rectangular groove of the gun head tube 2. Then, an internal hex bolt can be screwed into the L-shaped fixing block 6 and the gun head tube 2 for locking. At the same time, the head of the internal hex bolt can be hidden in the enlarged hole of the L-shaped fixing block 6.
[0035] Among them, the gun head tube 2 is provided with a threaded outer tube wall on the outside of the tube body near the T-shaped main half tube 8, and a swivel support ring 16 is screwed onto the threaded outer tube wall of the gun head tube 2.
[0036] By adopting the above technical solution, the gun head tube 2 can be fitted with the swivel support ring 16 for screw-on installation using the threaded tube wall.
[0037] It should be noted that this utility model is a root-oriented fertilizer applicator for agricultural planting. A fitting mechanism 3 is installed at the nozzle tube 2 of the fertilizer gun body 1. A spring 15 slides upwards from the head of the nozzle tube 2 along its straight section to the side of the tube near the fertilizer gun body 1. Then, the rotating support ring 16 of the fitting mechanism 3 can be screwed onto the nozzle tube 2 on the side of the spring 15. Next, the T-shaped main half-tube 8 and the T-shaped secondary half-tube 9 can be joined outside the spring 15 and the rotating support ring 16 to form a T-shaped threaded tube. At this time, the main hole block 10 can be inserted into the L-shaped rib 12. The insertion is positioned and locked in the L-shaped groove 13 of the auxiliary hole block 11. Then, the main hole block 10 and the auxiliary hole block 11 can be locked by screwing bolts, so as to ensure that the T-shaped main half tube 8 and the T-shaped auxiliary half tube 9 can be firmly assembled into a T-shaped threaded tube. Then, the cone cylinder 4 can be sleeved on the outside of the gun head tube 2 and screwed into the T-shaped threaded tube. At this time, the rectangular block formed by the L-shaped fixing block 6 and the double-hole liquid bladder block 7 can be inserted from the outlet 5 of the cone cylinder 4 and contact the gun head tube 2. Then, the L-shaped fixing block 6 is screwed and locked in the gun head tube 2 using an internal hex bolt.
[0038] When the fertilizer gun body 1 is screwed onto the pipe supplying liquid fertilizer, the grower can step on the pedal 14 to insert the cone-shaped tube 4 into the soil where the plant roots are located. When the cone-shaped tube 4 enters the soil, the L-shaped fixing block 6 and the double-mouth liquid bladder block 7 can block the outlet 5 to prevent soil from entering the cone-shaped tube 4 and the gun head tube 2. Then, the fertilizer gun body 1 is slightly lifted, so that the gun head tube 2, along with the L-shaped fixing block 6, squeezes the double-mouth liquid bladder block 7 at the outlet 5, deforming it. Then, the large and small liquid outlets of the double-mouth liquid bladder block 7 are squeezed and deformed. When the spring 15 inside the T-shaped threaded tube is pressed against the rotating support ring 16, it contracts elastically. At this time, the liquid chamber can be opened at the body 1 of the fertilizer gun, allowing the liquid fertilizer to flow from the inner cavity of the body 1 of the fertilizer gun along the nozzle tube 2 into the conical tube 4. Finally, the liquid fertilizer in the conical tube 4 can flow from the double-mouth liquid bag block 7 to the plant roots for directional fertilization. Then, the pedal 14 is released, the spring 15 loses pressure and elastically recovers, thereby re-locking the conical tube 4 with the nozzle tube 2. Then, the conical tube 4 can be pulled out upwards.
[0039] After the bolts at L-shaped block 6 are removed, L-shaped block 6 and double-hole liquid bladder block 7 can be disassembled and cleaned. Then, T-shaped threaded tube can be screwed off from cone cylinder 4, so that cone cylinder 4 can be removed for cleaning. Double-hole liquid bladder block 7 can be made of elastic rubber to give it good elastic deformation ability.
