Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural seedling cultivation technology, specifically to an agricultural seedling irrigation device. Background Technology
[0002] When irrigating seedlings in agriculture, water pumps draw water from the water source and deliver it through a pipeline system to various watering nozzles for seedling cultivation. The nozzles evenly disperse the water into tiny droplets, gently sprinkling the water onto the seedlings like a fine spring rain. The nozzles have a fine atomization effect, which can avoid damage to the seedlings caused by large amounts of water, such as knocking them over or breaking them.
[0003] Reference patent document: Patent Publication No. CN119302210B, Patent Publication Date 2025-05-02, discloses an agricultural seedling spraying device, relating to the field of spray irrigation technology, including a support plate and a nozzle assembly fixedly installed on the support plate; the nozzle assembly includes a fixed cylinder, a fixed ring rotatably installed on the upper part of the fixed cylinder, and a connecting seat fixedly installed at the bottom of the fixed cylinder, the connecting seat communicating with the fixed cylinder, the connecting seat being fixedly connected to the support plate, an inner cover fixedly installed on the fixed ring, multiple filter screens fixedly installed on the inner cover, a drain hole opened on the inner cover, and a blocking ring rotatably installed on the outside of the inner cover. The advantages are: the water power during the spraying process drives the inner cover and the spray head to rotate, which can not only change the spraying direction, but also change the maximum spraying range. At the same time, during the spraying process, the impact generated by the pulse is used to clean the impurities adhering to the filter screen, and the blocking ring is used to discharge the impurities, thereby improving the spraying efficiency.
[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:
[0005] Traditionally, irrigating seedlings is often accompanied by fertilization and the addition of nutrient supplements. However, current irrigation methods typically involve directly connecting pumped water to sprinkler heads via pipes. Since sprinkler heads cannot usually be connected to nutrient supplement bottles, fertilization cannot be performed simultaneously with irrigation. This forces fertilization and irrigation to be done in separate steps, increasing the time and labor costs of agricultural production and requiring more manpower to complete the irrigation and fertilization tasks separately.
[0006] Therefore, this utility model provides an agricultural seedling irrigation device. Utility Model Content
[0007] In order to solve the problem that traditional seedling irrigation devices cannot simultaneously carry out fertilization and irrigation, the purpose of this utility model is to provide an agricultural seedling irrigation device.

[0010] The mixing component, located at one end of the delivery pipe, is used to uniformly mix the nutrient solution and water.
[0011] Preferably, the mixing assembly includes a mixing box fixedly installed at one end of the delivery pipe, the other end of the mixing box fixedly installed at the middle of one side of the sprinkler head, two symmetrically distributed mixing blocks rotatably installed in the middle of the mixing box, gears fixedly installed at the bottom of the two mixing blocks, the two gears meshing with each other, and a drive motor fixedly installed at the bottom of the mixing box, with the middle of the bottom end of one of the gears fixedly installed at the drive end of the drive motor.
[0012] Preferably, the drive assembly includes a servo motor fixedly installed on one side of the lower part of the drug delivery tube, and the bottom end of the spiral conveying blade is fixedly installed on the drive end of the servo motor.
[0013] Preferably, a drug administration cap is threaded onto the upper side of the drug administration bottle, and the upper part of the drug administration cap has multiple anti-slip grooves distributed at equal intervals.
[0014] Preferably, a handle is fixedly installed on one side of the conveying pipe, and multiple anti-slip grooves are formed on the outer surface of the handle in a circular array.
[0015] Preferably, two symmetrically distributed protective covers are installed in the middle of the conveying pipe. The two protective covers are installed by bolts, and sealing rings are fixedly installed on opposite sides of the two protective covers.
[0016] Beneficial effects
[0017] This utility model provides an agricultural seedling irrigation device. Compared with the prior art, it has the following advantages:
[0018] Beneficial effects:
[0019] 1. This application uses a servo motor to drive the spiral conveyor blade to rotate, quantitatively delivering the nutrient solution in the dosing bottle to the delivery pipe to mix with the water flow. Combined with the one-way flow function of the check valve, it effectively prevents the backflow of clear water and contamination of the nutrient solution, ensuring that the seedlings receive a precise ratio of nutrient supplementation, thereby significantly improving the efficiency of crop management and enabling fertilization and irrigation to be carried out simultaneously.
[0020] 2. This application uses a drive motor to rotate two meshing gears, causing two mixing blocks to rotate relative to each other in the mixing box, generating shear force to quickly stir and mix the nutrient solution and water. This ensures that the mixture is fully homogenized before being sprayed out through the sprinkler head, avoiding excessively high local concentrations that could burn seedlings or insufficient concentrations that could affect fertilizer efficiency. This significantly improves the uniformity and safety of irrigation and fertilization. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-4 This utility model provides a technical solution: an agricultural seedling irrigation device, including a sprinkler head 1, with a dispensing mechanism 2 on one side of the sprinkler head 1 for replenishing nutrient solution during irrigation. The dispensing mechanism 2 includes:
[0028] The drug delivery assembly 21 includes a delivery pipe 211 disposed on one side of the sprinkler head 1. The delivery pipe 211 is made of high-strength PVC material, possessing good corrosion resistance and pressure resistance, and can adapt to the erosion of various chemical substances and changes in water pressure in agricultural irrigation environments. A check valve 212 is threaded in the middle of the delivery pipe 211. This check valve 212 is a spring-loaded one-way valve structure, with its flow direction from the drug delivery pipe 213 to the delivery pipe 211. It effectively prevents clean water from entering the drug delivery pipe 213, ensuring a stable one-way delivery of water and nutrient solution in the irrigation system. The other side of the check valve 212 is threaded with... The device is equipped with a drug delivery tube 213, and a spiral conveying blade 214 is rotatably installed in the middle of the drug delivery tube 213. The spiral conveying blade 214 is made of stainless steel and the surface is polished, which not only reduces the adhesion residue of nutrient solution during the delivery process, but also improves the delivery efficiency. At the same time, the outer side of the spiral conveying blade 214 is in close contact with the inner wall of the drug delivery tube 213 to ensure quantitative drug delivery. The lower part of the spiral conveying blade 214 is equipped with a drive assembly, and the upper part of the delivery tube 211 is threaded with a drug delivery bottle 216. The drug delivery bottle 216 is made of transparent food-grade plastic, which makes it convenient for operators to observe the remaining amount of nutrient solution in the bottle and replenish it in time.
[0029] The mixing component 22 is located at one end of the delivery pipe 211 and is used to uniformly mix the nutrient solution and water.
[0030] The mixing assembly 22 includes a mixing box 221 fixedly installed at one end of the delivery pipe 211, and the other end of the mixing box 221 fixedly installed at the middle of one side of the sprinkler head 1. Both ends of the mixing box 221 are connected to the delivery pipe 211 and the sprinkler head 1 respectively through flanges. Two symmetrically distributed mixing blocks 222 are rotatably installed in the middle of the mixing box 221. Gears 224 are fixedly installed at the bottom of the two mixing blocks 222, and the two gears 224 are meshed with each other. A drive motor 223 is fixedly installed at the bottom of the mixing box 221. The bottom middle of one of the gears 224 is fixedly installed at the drive end of the drive motor 223. The drive motor 223 is a 39HS type stepper motor, which can control the rotation speed of the two mixing blocks 222 according to the drug administration situation, thereby ensuring the uniform mixing of water and nutrient solution.
[0031] The drive assembly includes a servo motor 215 fixedly mounted on one side of the lower part of the drug delivery tube 213, and the bottom end of the spiral delivery blade 214 fixedly mounted on the drive end of the servo motor 215. The servo motor 215 is a micro servo motor of model PD6, which can control the rotation speed of the spiral delivery blade 214 under its drive, thereby controlling the drug delivery amount.
[0032] A drug administration cap 217 is threaded onto the upper side of the drug administration bottle 216. The upper part of the drug administration cap 217 has multiple anti-slip grooves that are evenly spaced, so that the operator can easily open and close the drug administration cap 217 and put nutrient solution and other supplements into the drug administration bottle 216.
[0033] A handle 2111 is fixedly installed on one side of the delivery pipe 211. Multiple anti-slip grooves are distributed in a ring array on the outer surface of the handle 2111. Workers can hold the handle 2111 to pick up the sprinkler head 1 to water the seedlings.
[0034] Two symmetrically distributed protective covers 218 are installed in the middle of the conveying pipe 211. The two protective covers 218 are installed by bolt splicing, and sealing rings are fixedly installed on the opposite sides of the two protective covers 218. The servo motor 215, drive motor 223 and check valve 212 are all located inside the protective cover 218 to protect them and prevent the equipment's service life from being reduced due to the long-term effects of impurities, dust and water.
[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0036] During operation, the delivery pipe 211 is connected to an external water supply pipe, allowing water to flow through the delivery pipe 211 and the mixing tank 221. The water is then evenly sprayed out through the sprinkler head 1 to irrigate the crop seedlings. Simultaneously, when fertilization is needed during irrigation, the dosing cap 217 can be opened to place the nutrient solution into the dosing bottle 216. By starting the servo motor 215, the spiral conveying blade 214 is rotated, transporting the nutrient solution through the dosing pipe 213 and the check valve 212 to the delivery pipe 211 to mix with the water. The solution then flows into the mixing tank 221. The drive motor 223 starts, driving two meshing gears 224 to rotate, which in turn drives two mixing blocks 222 to rotate relative to each other. This ensures that the nutrient solution entering the mixing tank 221 is fully mixed with the water. The mixture is then evenly sprayed out through the sprinkler head 1, thus supplementing the nutrient solution for the crop seedlings while irrigating.
