Description

Technical Field

[0001] The utility model relates to the field of fertilization devices, in particular to a root irrigation fertilization device for corn cultivation. Background Art

[0002] Corn is one of the most important food crops in the world and an important cash crop in many countries. In the process of corn cultivation, root fertilization is a very important part, which can improve corn yield and quality while reducing fertilizer waste.

[0003] By researching and developing new root fertilization devices for corn cultivation, we can achieve the goals of precise fertilization, improving fertilizer utilization, reducing pesticide residues, and providing better technical support for corn production. Such devices must take into account the growth characteristics of corn, such as root growth depth, growth rate and other factors, to ensure that fertilizer can be effectively transported to the corn root system and achieve accurate and uniform fertilizer spraying.

[0004] At present, the root fertilization device for corn cultivation mixes water and fertilizer in a certain proportion, and then transports the mixture through a pipe to a drip irrigation pipe laid on the ground of the corn field. The fertilizer solution is then transported to the drip irrigation point, and the fertilizer solution is drip-irrigated around the roots of the corn plants through a dripper. However, the drip irrigation pipe is mostly a whole and cannot be changed according to the planting density of corn and the land conditions. This may cause the drip irrigation pipe to be entangled, and the fertilizer solution to be transported unevenly, resulting in low fertilizer utilization. Secondly, the fertilizer and water are not mixed well, and the efficiency is low. Therefore, a root fertilization device for corn cultivation is proposed to solve the above problems. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The water outlet 11 flows into the delivery pipe 12, and the outer wall of the delivery pipe 12 is fixedly connected with an installation node 13. Both ends of the installation node 13 are detachably connected with a drip irrigation pipe 14. There are multiple groups of installation nodes 13. The drip irrigation pipe 14 can be installed on different installation nodes 13 to control the interval between them. The outer wall of the drip irrigation pipe 14 is provided with a drip hole 15, and the water and fertilizer flow out little by little through the drip hole 15 and flow into the root of the corn. The inner wall of the installation node 13 is fixedly connected with a rubber sealing ring 20, and the outer wall of the rubber sealing ring 20 is in contact with the end of the drip irrigation pipe 14. When the drip irrigation pipe 14 is installed on the installation node 13, the rubber sealing ring 20 is squeezed to ensure the sealing performance, and a valve can be set on the installation node 13 or a protective cover can be installed to prevent water and fertilizer leakage when not in use. The inner wall of the drip irrigation pipe 14 is elastically connected with a buckle assembly through a reset spring 16. The buckle assembly includes a clamping block 17. One end of the reset spring 16 is fixedly connected to the inner side of the clamping block 17, and the other end of the reset spring 16 is fixedly connected to the inner wall of the drip irrigation pipe 14. The surface of the clamping block 17 is set as an inclined surface. In the process of inserting the drip irrigation pipe 14 into the installation node 13, the inner wall of the installation node 13 squeezes the clamping block 17 obliquely. The surface squeezes the return spring 16 to retract. At the same time, the elastic force generated by the deformation of the return spring 16 gives the block 17 an elastic force in the opposite direction to reset it. A card slot 18 is provided on the inner wall of the mounting node 13. The outer wall of the card block 17 is snapped with the inner wall of the card slot 18. After the drip irrigation pipe 14 is fully inserted into the mounting node 13, the card block 17 pops out and is snapped into the card slot 18 to fix it on the mounting node 13. A pressing block 19 is slidably connected to the inner wall of the mounting node 13. The inner side of the pressing block 19 is in contact with the outer wall of the card block 17. Pressing the pressing block 19 inwards can press the card block 17 out of the card slot 18.

[0031] Reference Figure 1 and Figure 3A motor 4 is welded to the top of the top cover 3, and a turntable 5 is fixedly connected to the output shaft of the motor 4. The inner wall of the turntable 5 is rotatably connected to a rotating shaft 6. Starting the motor 4 can make the turntable 5 drive the rotating shaft 6 to make a circular motion. A gear 7 is fixedly connected to the top of the rotating shaft 6, and an inner gear ring 8 is fixedly connected to the inner wall of the top cover 3. The inner wall of the inner gear ring 8 meshes with the outer wall of the gear 7. A plurality of stirring structures 9 are fixedly connected to the outer wall of the rotating shaft 6. The circular motion of the rotating shaft 6 can make the gear 7 rotate while making a circular motion due to the inner gear ring 8, thereby driving the stirring structure 9 to rotate, thereby greatly improving the stirring effect and improving the water-fertilizer mixing efficiency.

[0032] Working principle: water is pumped into the mixing bin 1 through the water pumping port 2, and fertilizer is put into the mixing bin 1 through the feed port 10, the motor 4 is started to drive the turntable 5 to rotate, thereby driving the rotating shaft 6 and the gear 7 to make a circular motion. At the same time, the gear 7 drives the rotating shaft 6 to rotate under the action of the inner gear ring 8, and drives the stirring structure 9 to rotate while making a circular motion, thereby improving the mixing effect of fertilizer and water and improving the mixing efficiency. After that, the water-stop fertilizer is opened to enter the delivery pipe 12 through the water outlet 11, and then flows into the drip irrigation pipe 14 through the delivery pipe 12, and flows into the corn root through the drip hole 15 for fertilization. It needs to be based on the corn planting density. When adjusting the intervals between multiple groups of drip irrigation pipes 14 according to land conditions, press the pressing block 19 inward to squeeze the reset spring 16 to retract the card block 17 and release the card connection with the card slot 18. At this time, the drip irrigation pipe 14 can be removed from the installation node 13, and a protective cover is installed on the installation node 13 to prevent leakage. Then, the drip irrigation pipe 14 is inserted into other installation nodes 13, and the card block 17 is squeezed and retracted by the inner wall of the installation node 13. After it is fully inserted, the reset spring 16 pushes the card block 17 into the card slot 18, thereby fixing the drip irrigation pipe 14 on the installation nodes 13 with appropriate intervals, thereby preventing the drip irrigation pipe 14 from being entangled and causing the fertilizer utilization rate to be low.
