Description

Technical Field

[0001] This utility model relates to the technical field of crop fertilization, specifically to a fertilization device for crops grown under plastic film. Background Technology

[0002] Mulching technology, with its significant advantages in water retention, fertilizer retention, temperature increase, and weed suppression, is widely used in the cultivation of crops such as peanuts and cotton. Traditional fertilization methods for mulched crops often involve manual breaking of the film. This method not only consumes a lot of manpower, but frequent breaking of the film can also easily lead to damage to the mulch, impairing its heat and moisture retention effects, affecting its regulatory role on the soil microenvironment, and ultimately reducing crop yield and quality.

[0003] To address the drawbacks of manual fertilization, existing plastic film crop fertilization devices mostly employ pipeline laying for integrated water and fertilizer operation. However, the pipeline laying lacks flexibility and is difficult to adjust according to the planting row spacing of crops, failing to meet diverse planting needs and limiting the device's applicability. Utility Model Content

[0004] This utility model proposes a special fertilization device for mulched crops. By using the elastic expansion and contraction of the corrugated pipe in the connecting mechanism, it can adapt to different planting row spacings of crops and improve the versatility of the device.

[0005] Therefore, the technical solution adopted is as follows: A fertilizer application device for plastic film-covered crops includes a main fertilizer delivery pipe, which is connected to multiple branch pipes via a connecting mechanism. Each branch pipe is connected to multiple fertilizer application branch pipes. The connecting mechanism includes a movable block fixed to the branch pipes. The movable block has a cross-shaped through hole inside. Each side of the movable block has a connecting ring that is coaxially fixed and connected to the main fertilizer delivery pipe. A corrugated pipe is connected between each of the two connecting rings and the movable block. The movable block is connected to the corrugated pipe and the branch pipes respectively through the cross-shaped through hole.

[0006] A further technical solution is that an adjusting slide rod is fixed between the two connecting rings, a limit block is fixed on the movable block, and the adjusting slide rod passes through the limit block and is slidably connected to it.

[0007] A further technical solution is that the limiting block has a threaded hole, and an adjusting screw passes through the threaded hole. The adjusting screw can be rotated to abut against an adjusting slide rod passing through the inside of the limiting block.

[0008] A further technical solution is that a main valve is connected to the main fertilizer conveying pipe, and a branch valve is connected to each branch pipe.

[0009] A further technical solution is that the fertilizer application branch pipe includes a flexible hose, one end of which is connected to a branch pipeline, and the other end is fixedly connected to a discharge head.

[0010] A further technical solution is that a positioning cone is fixed on the discharge head, and the tip of the positioning cone is inserted into the ground for fixation.

[0011] The working principle and beneficial effects of this application are as follows: 1. The elastic expansion and contraction of the bellows in the connecting mechanism allows the movable block to slide along the adjusting slide rod and fix its position using the adjusting screw, thereby adjusting the spacing between adjacent branch pipes to adapt to different planting row spacings for different crops and improving the versatility of the device.

[0012] 2. The movable block has cross-shaped through holes inside, so that the branch pipes are always perpendicular to the main fertilizer conveying pipe. This regular layout avoids local resistance changes caused by bending of the branch pipes and ensures smooth flow of fluid in the pipeline.

[0013] 3. A flexible hose is installed on the final fertilization branch pipe and is finally fixed by a positioning cone. This allows the hose to be rotated to a certain extent to accurately locate the planting position of each row of crops and apply fertilizer, compensating for errors in crop planting spacing and ensuring that fertilization is in place.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figures 1-4 As shown, a fertilizer application device for plastic film-covered crops includes a main fertilizer delivery pipe 1. The main fertilizer delivery pipe 1 is connected to multiple branch pipes 3 via a connecting mechanism 2. Each branch pipe 3 is connected to multiple fertilizer application branch pipes 4. The connecting mechanism 2 includes a movable block 23 fixed to the branch pipes 3. The movable block 23 has a cross-shaped through hole inside. Each side of the movable block 23 has a connecting ring 21 that is coaxially fixed and connected to the main fertilizer delivery pipe 1. A corrugated pipe 22 is connected between each of the two connecting rings 21 and the movable block 23. The movable block 23 is connected to the corrugated pipe 22 and the branch pipes 3 respectively through the cross-shaped through hole.

[0019] In this embodiment, by laying branch pipes 3 in farmland where crops are cultivated, and covering the crops and branch pipes 3 with plastic film, the main fertilizer conveying pipe 1 is connected to the branch pipes 3 through the connecting mechanism 2. After mixing fertilizer and water to form water-soluble fertilizer, it is transported to the main fertilizer conveying pipe 1 through equipment such as a water pump. The fertilizer solution flows from the branch pipes 3 into the fertilizer application branch pipes 4, and finally the fertilizer is accurately applied to the vicinity of the crop roots, so as to achieve the effect of not damaging the plastic film and the fertilizer being evenly applied to the soil around the crop roots.

[0020] The device utilizes a connecting ring 21, a corrugated pipe 22, and a movable block 23. By leveraging the expansion and contraction characteristics of the corrugated pipe 22, the movable block 23 is adjusted to move the branch pipes 3, thereby flexibly adjusting the spacing between the branch pipes 3 to meet the laying requirements of different crop row spacings and improve the versatility of the device. In addition, the branch pipes 3 are always perpendicular to the main fertilizer conveying pipe 1. This regular layout avoids local resistance changes caused by bending of the branch pipes 3, ensuring smooth fluid flow in the pipeline.

[0021] like Figure 3 As shown, an adjusting slide rod 26 is fixed between the two connecting rings 21, and a limiting block 24 is fixed on the movable block 23. The adjusting slide rod 26 passes through the limiting block 24 and is slidably connected to it. In this embodiment, the adjusting slide rod 26 passes through the limiting block 24 and is installed between a pair of connecting rings 21 to provide guidance for the sliding of the movable block 23, limit its movement direction, and ensure stability during adjustment.

[0022] Based on this, a threaded hole is provided on the limiting block 24, and an adjusting screw 25 passes through the threaded hole. The adjusting screw 25 can be rotated to abut against the adjusting slide rod 26 passing through the inside of the limiting block 24. The adjusting screw 25 is threadedly connected to the limiting block 24. After tightening, the limiting block 24 is fixed on the adjusting slide rod 26, locking the position of the branch pipe 3 and preventing the movable block 23 from loosening due to the force of water flow.

[0023] like Figure 1 As shown, a main valve 5 is installed on the main fertilizer conveying pipe 1, and branch valves 6 are installed on the branch pipes 3. The main valve 5 is installed on the main fertilizer conveying pipe 1 to control the fluid flow and total flow of the entire fertilization system, facilitating system start-up, shutdown, and overall adjustment. The branch valves 6 are installed on each branch pipe 3, allowing for individual control of the flow and flow of each branch pipe 3, adapting to the fertilization needs of crops in different areas, improving flexibility, and accommodating situations where different crop types and planting spacings exist within a single farmland.

[0024] like Figure 4 As shown, the fertilizer application branch pipe 4 includes a flexible hose 41. One end of the flexible hose 41 is connected to the branch pipe 3, and the other end is fixedly connected to a discharge head 42. The flexible hose 41, connected to the branch pipe 3, is made of flexible material and can be bent to adjust the position of the discharge head 42, allowing the discharge head to accurately apply fertilizer to the soil around the peanut roots. Additionally, a positioning cone 43 is fixed to the discharge head 42, with its tip inserted into the ground for fixation. The positioning cone 43, once inserted into the soil, fixes the position of the discharge head 42, preventing displacement of the discharge head 42 due to water pressure or external forces during fertilization, thus ensuring stable fertilization placement.

[0025] During use, the branch pipe 3 is laid in the farmland where crops are cultivated. The branch pipe 3 is connected to the fertilizer conveying main pipe 1 through the connecting mechanism 2. The movable block 23 in the connecting mechanism 2 is adjusted, and the sliding limit block 24 is slid through the adjusting rod 26 to adjust the spacing between adjacent branch pipes 3. The adjusting screw 25 is tightened to fix the position. The discharge head 42 of the fertilizer branch pipe 4 is inserted into the soil through the positioning cone 43 and aligned with the vicinity of the crop roots. Then, the mulch film is used to cover both the crops and the branch pipe 3 to reduce water and fertilizer evaporation. The fertilizer and water are mixed in proportion to form water-soluble fertilizer. The main valve 5 on the fertilizer conveying main pipe 1 and the branch valve 6 on the branch pipe 3 are opened. The water-soluble fertilizer flows into the branch pipe 3 through the fertilizer conveying main pipe 1 and is then discharged from the discharge head 42 through the hose 41 of the fertilizer branch pipe 4, and is precisely applied to the area around the crop roots.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
