Description

Technical Field

[0001] This utility model relates to the field of fertilizer spreading devices, and in particular to an adjustable continuous fertilizer spreading device. Background Technology

[0002] Scientific fertilization is key to ensuring high yield and quality of crops. Liquid fertilizers are highly soluble and easily absorbed, and can distribute nutrients evenly and cover a wider area. Atomized spraying allows nutrients to penetrate the root system quickly, improving utilization and reducing volatilization and leaching, making them suitable for efficient operations in precision agriculture.

[0003] Most existing liquid fertilizer spraying devices adopt a fixed design, with multiple nozzle water boxes rigidly connected to the bracket by welding or bolts to carry out horizontal planar spraying operations. However, due to the different row spacing of crops, nozzles without lateral displacement adjustment function can only carry out directional spraying on fixed areas, which can easily lead to repeated spraying or omission of adjacent crops, affecting nutrient uniformity and increasing unnecessary fertilizer consumption. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing sprayers, which lack lateral displacement adjustment, can only perform directional spraying on fixed areas, easily causing repeated spraying or omission of adjacent crops, which affects nutrient uniformity and increases excessive fertilizer consumption. Therefore, an adjustable continuous fertilizer spreading device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable continuous fertilizer spreading device includes a mobile vehicle with a mounting base fixed on its top. A lifting plate slides vertically on the mounting base. A pair of movable seats are provided on the mounting base. A fixed shaft is fixed on both the lifting plate and the movable seats. The same traction plate is rotatably sleeved on the two fixed shafts. A connecting plate is fixed on the top of the movable seats. A limit rod is fixed on the connecting plate. The limit rod is horizontally slidably connected to the mounting base.

[0007] Preferably, a lead screw is rotatably connected to the top of the mobile vehicle, a motor for driving the lead screw to rotate is fixed on the mounting base, and a sliding opening is provided on the mounting base to facilitate the movement of the traction plate.

[0008] Preferably, the mobile vehicle is provided with a liquid storage tank on the top, a power pump is provided on the top of the liquid storage tank, a temporary storage box is provided on the mobile seat, and multiple spray heads are installed at the bottom of the temporary storage box. The power pump and the temporary storage box are fixedly connected to the same hose on opposite side walls.

[0009] Preferably, a plug is fixedly connected to the temporary storage box, a pair of screws are threadedly connected to the movable seat, a clamp is rotatably connected to one end of the screw, a slide rod is fixedly connected to the clamp, and the slide rod and the movable seat are horizontally slidably connected.

[0010] Preferably, the opposite sidewalls of the two clamps are in contact with the insert block.

[0011] Preferably, a threaded ring tube is fixedly provided at the end of the hose away from the power pump, and a threaded tube is fixedly provided on the temporary storage box, and the threaded tube and the threaded ring tube are threadedly connected.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This invention, through the design of components such as a traction plate and a movable seat, enables the motor to be started when spraying liquid fertilizer. Under the coordinated action of the motor and the traction plate, the movable seat drives the temporary storage box to move horizontally and flexibly, allowing the spray head to move horizontally to spray fertilizer onto crops in different horizontal areas and with different row spacings. This ensures the uniformity and comprehensiveness of the spraying and improves the flexibility of the device. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-4 An adjustable continuous fertilizer spreading device includes a mobile vehicle 1, a mounting base 2 fixed to the top of the mobile vehicle 1, a lifting plate 3 sliding vertically on the mounting base 2, and a pair of movable seats 4 mounted on the mounting base 2. Both the lifting plate 3 and the movable seats 4 are fixed with a fixed shaft 41. A traction plate 42 is rotatably mounted on the two fixed shafts 41. The traction plate 42 rotates through the fixed shafts 41, converting the vertical movement of the lifting plate 3 into the horizontal displacement of the movable seats 4. A connecting plate 43 is fixed to the top of the movable seats 4, and a limit rod 44 is fixed to the connecting plate 43. The limit rod 44 provides a preset trajectory and support force for the horizontal movement of the movable seats 4, ensuring stable horizontal movement of the movable seats 4. The limit rod 44 and the mounting base 2 are horizontally slidably connected.

[0027] A lead screw 31 is rotatably connected to the top of the mobile vehicle 1. A motor 32 for driving the lead screw 31 to rotate is fixed on the mounting base 2. The motor 32 drives the lead screw 31 to rotate, causing the lifting plate 3 to move up and down. The mounting base 2 has a sliding opening 45 to facilitate the movement of the traction plate 42. The sliding opening 45 is designed to prevent the traction plate 42 from shifting horizontally.

[0028] The mobile vehicle 1 is equipped with a liquid storage tank 5 on its top. The liquid storage tank 5 features a large-capacity design, reducing the frequency of fertilizer refills and improving operational continuity. A power pump 6 is installed on top of the liquid storage tank 5, providing stable pressure to ensure smooth delivery of liquid fertilizer through the hose 8 to the temporary storage box 7. The flow rate is controllable, preventing uneven spraying or clogging. The temporary storage box 7 is mounted on the mobile base 4, and multiple spray nozzles are installed at the bottom of the temporary storage box 7. The power pump 6 and the temporary storage box 7 are fixedly connected to the same hose 8 on opposite side walls.

[0029] A plug 71 is fixedly connected to the temporary storage box 7. A pair of screws 73 are threadedly connected to the movable seat 4. A clamping plate 72 is rotatably connected to one end of the screws 73. A sliding rod 74 is fixedly connected to the clamping plate 72, and the sliding rod 74 and the movable seat 4 are horizontally slidably connected. By rotating the screws 73, the clamping plate 72 is pushed to slide along the sliding rod 74, thus achieving a stable clamping of the plug 71. The operation is simple, the locking is reliable, and it ensures that the temporary storage box 7 will not loosen or shift during operation, thereby improving the spraying accuracy.

[0030] The opposite sidewalls of the two clamping plates 72 are in contact with the insert block 71.

[0031] A threaded ring tube 81 is fixedly installed at the end of the hose 8 away from the power pump 6, and a threaded tube 82 is fixedly installed on the temporary storage box 7, with the threaded tube 82 and the threaded ring tube 81 being threadedly connected. The quick connection between the threaded ring tube 81 and the threaded tube 82 ensures good sealing and prevents liquid leakage, while also facilitating disassembly and maintenance.

[0032] The functional principle of this utility model can be explained through the following operation methods:

[0033] First, liquid fertilizer is added to the storage tank 5, and then the mobile vehicle 1 moves to the work area.

[0034] Then start the motor 32, drive the lead screw 31 to rotate and drive the lifting plate 3 to rise and fall vertically. At this time, the traction plate 42 is pulled by the fixed shaft 41, pushing the moving seat 4 to slide horizontally along the limit rod 44. The horizontal position of the spray head can be changed by adjusting the height of the lifting plate 3.

[0035] During the fertilization process, the power pump 6 is started to pump the fertilizer into the temporary storage box 7 through the hose 8. The liquid is evenly sprayed through the bottom spray head. During operation, the fertilizer spreading width can be changed by adjusting the height of the lifting plate 3 in real time: when raised, the moving seat 4 expands the spraying range, and when lowered, the spraying range is reduced. The traction plate 42 deflects adaptively within the sliding port 45 to maintain transmission stability.

[0036] When it is necessary to replace the temporary storage box 7, loosen the screw 73 so that the clamp 72 releases its grip on the insert block 71 through the guide of the slide bar 74, and remove the temporary storage box 7 from the moving base 4.

[0037] Then, loosen the threaded ring tube 81 so that it falls off the threaded tube 82, thus disassembling the temporary storage box 7. The removable temporary storage box 7 facilitates subsequent cleaning and maintenance by the operator.

[0038] The device achieves fertilizer application range adjustment through mechanical linkage, and the flexible connection of the hose 8 ensures normal operation of the moving parts, thus realizing precise and controllable continuous fertilizer application.

[0039] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
