Detailed Implementation

[0016] 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.

[0017] Example 1 This embodiment provides a rice soil fertilizer application control device, such as... Figure 1-5As shown, the fertilizer application control device includes a support shell 1. A double-acting screw 2 is rotatably mounted on the left and right sides of the support shell 1 via bearings. A T-shaped slider 3 is threadedly mounted on the left and right sides of the double-acting screw 2. A disassembly and assembly structure 4 is mounted on the side wall of the T-shaped slider 3. A storage cylinder 5 is mounted on the disassembly and assembly structure 4. A stirring structure 6 is mounted on the storage cylinder 5. The disassembly and assembly structure 4 includes a collar 41 installed on the side wall of the T-shaped slider 3. The left and right sides of the collar 41 are equipped with mounting plates 42 through slots 4101, and two sets of L-shaped plates 43 symmetrically arranged on the outer wall of the collar 41. The L-shaped plates 43 are equipped with screws 44 through threaded holes. A locking block 45 is rotatably installed at one end of the screw 44 near the mounting plate 42, and a knob 46 is provided at the other end of the screw 44.

[0018] In use, when the two sets of storage cylinders 5 and their components on the rice soil fertilizer application control device are damaged, the damaged set of storage cylinders 5 can be disassembled individually. By rotating the left and right sets of knobs 46 counterclockwise on the L-shaped plate 43, the screw 44 rotates the connecting plate 47, causing the connecting plate 47 to move the locking block 45 out of the limiting groove 4201, thus freeing the mounting plate 42. This drives the storage cylinder 5, along with the two sets of mounting plates 42, to move upwards from the corresponding locking groove 4101. The storage cylinder 5, along with the stirring structure 6, solenoid valve 7, and discharge pipe 8, is then removed upwards from the collar 41, enabling quick disassembly of the storage cylinder 5. This facilitates the repair of the storage cylinder 5 and its components, including the stirring structure 6, solenoid valve 7, and discharge pipe 8. If the storage cylinder 5 and its components are severely damaged and the repair cost is high, the storage cylinder 5 and its components can be replaced. During installation, the storage cylinder 5 and its components are driven to pass through the upper and lower parts of the collar 41, carrying the solenoid valve 7 and the discharge pipe 8. The storage cylinder 5, along with two sets of mounting plates 42, enters the corresponding two sets of slots 4101. Then, the two sets of knobs 46 are driven to rotate the screw 44 clockwise on the L-shaped plate 43. The screw 44, through the connecting plate 47, drives the locking block 45 into the limiting groove 4201, thereby controlling the up and down movement of the mounting plate 42. This completes the quick installation of the storage cylinder 5 and its components, facilitating disassembly, maintenance, and rapid replacement of the storage cylinder 5 and its components. This avoids the problem that the fertilizer storage box of the existing rice soil fertilizer application control device is fixedly installed on a rectangular steel sleeve, making it inconvenient to disassemble, repair, or replace the fertilizer storage box and fertilizer application device when they are damaged. This improves the efficiency of repairing and replacing the storage cylinder 5 and its components.

[0019] In this embodiment, a through groove 4102 is provided on the collar 41 corresponding to the locking block 45. The collar 41 is slidably connected to the locking block 45 through the through groove 4102. The corresponding side walls of the two sets of mounting plates 42 are connected to the outer wall of the storage cylinder 5. A limiting groove 4201 adapted to the locking block 45 is provided on the mounting plate 42. A connecting plate 47 is provided at one end of the screw 44 near the mounting plate 42. A connecting hole 4501 is provided on the locking block 45. The locking block 45 is rotatably connected to the connecting plate 47 through the connecting hole 4501. A guide block 48 is installed at the bottom of the inner cavity of the L-shaped plate 43. A sliding groove 4502 slidably connected to the guide block 48 is provided at the bottom of the locking block 45. The sliding groove 4502 and guide block 48 are configured such that when the locking block 45 moves away from the limiting groove 4201, it passes through the through groove 4102 and is slidably connected to the guide block 48 through the sliding groove 4502, thereby ensuring that the locking block 45 is always in a stable sliding state, which facilitates the quick assembly and disassembly of the storage cylinder 5. In this embodiment, a solenoid valve 7 is installed at the bottom of the storage cylinder 5 via a connector, and a discharge pipe 8 is installed at the discharge end of the solenoid valve 7 via a connector; a second motor 9 is installed on the left side wall of the support shell 1, and the drive end of the second motor 9 is connected to the left end of the bidirectional lead screw 2; two sets of support plates 10 are installed on the end face and bottom of the support shell 1; a discharge port 11 and two sets of handles 12 symmetrically installed on the outer wall of the storage cylinder 5 are provided on the end face of the storage cylinder 5. The system includes a feeding pipe 8 and a second motor 9. The feeding pipe 8 is started and stopped via the control panel, allowing fertilizer in the storage cylinder 5 to enter the second motor 9 through the feeding pipe 8 and then fertilize the rice soil through the second motor 9. The handle 12 allows the storage cylinder 5 to be lifted upwards or placed downwards into the collar 41 by hand, thus facilitating the assembly and disassembly of the storage cylinder 5.

[0020] Example 2 Unlike Example 1, when fertilizing rice, multiple fertilizers are usually mixed before application. However, existing rice soil fertilizer application control devices lack a stirring function, which leads to uneven mixing of multiple fertilizers and differences in rice growth. Therefore, the stirring structure 6 includes a first motor 61 installed on the end face of the storage cylinder 5. The drive end of the first motor 61 and the inside of the storage cylinder 5 are provided with a rotating shaft 62. Stirring rods 63 are symmetrically installed on the outer wall of the rotating shaft 62 on the front and rear sides. In use, multiple fertilizers are successively introduced into the inner cavity of the storage cylinder 5 through the discharge port 11. The first motor 61 is started by the control switch. The first motor 61 drives the rotating shaft 62 to rotate, and the rotating shaft 62 drives multiple sets of stirring rods 63 to rotate. Under the rotation of the multiple stirring rods 63, the multiple fertilizers in the inner cavity of the storage cylinder 5 are stirred, so that the multiple fertilizers are evenly mixed. The evenly mixed fertilizer is then applied to the rice soil. This avoids the problem of uneven mixing of multiple fertilizers and differences in rice growth caused by the lack of stirring function in the existing rice soil fertilizer application control device. This makes the rice soil fertilizer application control device more effective. In this embodiment, multiple sets of stirring rods 63 are provided, and the multiple sets of stirring rods 63 are evenly distributed along the axial outer wall of the rotating shaft 62.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
