Description

Technical Field

[0001] This utility model relates to the field of fertilization technology, specifically to an agricultural fertilization device. Background Technology

[0002] Agricultural fertilization refers to agricultural techniques that apply fertilizer to the soil or spray it on plants to provide the nutrients needed by the plants and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, enrich the soil, and improve economic benefits.

[0003] Patent document CN221829461U discloses an agricultural fertilization control device. By incorporating a stirring mechanism, it can uniformly mix various fertilizers during use. By setting a metering mechanism, it ensures consistent fertilizer amounts in each planting hole, which is beneficial for ensuring planting quality and improving ease of use. While the device can dispense fertilizer in measured quantities, the dispensed fertilizer cannot be effectively dispersed. Furthermore, if the outlet is blocked, the material cannot be discharged evenly.

[0004] Patent document CN223110516U discloses an agricultural fertilization control device. It features a fertilizer bin for holding the required fertilizer. A first motor drives a second gear, which in turn rotates a first rotating rod, causing a dispensing disc to rotate. Simultaneously, a spiral auger rotates, evenly distributing the fertilizer from the fertilizer bin. The fertilizer then falls onto the dispensing disc, where a dispensing plate evenly spreads it. This device is suitable for both solid organic and inorganic fertilizers. While the device allows fertilizer to fall at a uniform speed and be evenly distributed, it only allows for circumferential distribution, not directional application. When fertilization is needed on the sides of a field ridge where plants are growing, the device may distribute the fertilizer to the left and right sides of the ridge, resulting in waste. Utility Model Content

[0005] The main purpose of this invention is to provide an agricultural fertilization device that can ensure uniform discharge of waste and directionally scatter the discharged waste.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] An agricultural fertilization device includes a mounting plate with a hopper fixed on it. A mixing unit is installed inside the hopper. A discharge pipe is fixedly connected to the lower end of the hopper, and a spray pipe is fixedly connected to the lower end of the discharge pipe. An air pump is fixed to the rear end of the spray pipe, and the air outlet of the air pump is connected to the spray pipe. A nozzle is installed at the front end of the spray pipe. Two fixing frames are fixed to the lower end of the mounting plate, and a walking unit is installed at the lower end of the fixing frames. A clearing unit is installed inside the discharge pipe. The lower end of the clearing unit passes through the spray pipe and is connected to the walking unit. During operation, the clearing unit can move inside the discharge pipe and ensure that fertilizer flows smoothly from the discharge pipe into the spray pipe.

[0008] Specifically, the unblocking unit reciprocates within the discharge pipe along the axial direction of the discharge pipe.

[0009] Specifically, the walking unit includes a rotating shaft rotatably connected to the lower end of the fixed frame, with two rollers concentrically fixed on the rotating shaft, and a cam fixed on the rotating shaft between the two rollers; the unblocking unit includes a square rod, the upper end of which passes through the spray pipe and extends into the discharge pipe, the square rod and the spray pipe are elastically and slidably sealed together, the square rod and the discharge pipe are concentric, a cross plate is fixed to the upper end of the square rod, and multiple unblocking columns are fixed to the upper end of the cross plate, and the lower end of the square rod contacts the outer edge of the cam.

[0010] Specifically, the lower end of the square rod is arc-shaped.

[0011] Specifically, a fixing block is fixed on the square rod below the spray tube, and a spring is sleeved on the square rod between the fixing block and the spray tube. The upper end of the spring is pressed against the lower end of the spray tube, and the lower end of the spring is pressed against the upper end of the fixing block.

[0012] Specifically, the unblocking unit rotates inside the discharge pipe.

[0013] Specifically, the walking unit includes a rotating shaft rotatably connected to the lower end of the fixed frame, with two rollers concentrically fixed on the rotating shaft, and a second bevel gear concentrically fixed on the rotating shaft between the two rollers; the unblocking unit includes a spiral auger located inside the discharge pipe, with the spiral auger concentric with the discharge pipe, and a rotating rod concentrically fixed at the lower end of the spiral auger, the rotating rod passing through the spray pipe, the rotating rod being rotatably and sealingly connected to the spray pipe, and a first bevel gear concentrically fixed at the lower end of the rotating rod, the first bevel gear meshing with the second bevel gear.

[0014] Specifically, the axial direction of the spray pipe is parallel to the travel direction of the device.

[0015] Specifically, the mounting plate has two support rods fixed at its lower end and a handrail fixed at its upper end.

[0016] Specifically, the stirring unit includes a connecting plate fixed to the upper end of the hopper, a motor fixed on the connecting plate, a stirring shaft concentrically fixed on the output shaft of the motor, the stirring shaft being located inside the hopper, a scraper fixed on the stirring shaft, and the scraper slidingly contacting the inner wall of the hopper.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The mixing unit effectively mixes different types of fertilizers in the hopper, ensuring a uniform distribution of fertilizer components. This avoids the time-consuming and labor-intensive problem of manual mixing, improving fertilization quality and crop absorption efficiency. The design of the scraper sliding in contact with the inner wall of the hopper further prevents fertilizer adhesion and reduces residue waste.

[0019] 2. The unblocking unit operates during the device's movement, continuously clearing fertilizer buildup in the discharge pipe via the walking unit. This effectively eliminates the risk of blockage caused by damp or clump-forming fertilizer, ensuring a smooth flow of fertilizer from the hopper to the spray pipe without manual intervention, thus improving operational continuity and reliability.

[0020] 3. The air pump can spray fertilizer evenly in the form of airflow, and the axis of the spray pipe is parallel to the direction of travel, ensuring that the fertilizer accurately covers the field ridges. This avoids the waste and local over-application problems of traditional fertilization. At the same time, the start and stop control of the air pump simplifies the operation and achieves rapid and large-area fertilization results.

[0021] 4. The overall design of the device facilitates pushing and moving. The walking unit automatically triggers the dredging unit to work during movement, forming an integrated operation. This significantly reduces the need for manual dredging, making it particularly suitable for long-distance field operations, thus improving user experience and work efficiency.

[0032] A dredging unit is installed inside the discharge pipe 13. The lower end of the dredging unit passes through the spray pipe 14 and is connected to the traveling unit.

[0033] During operation, the dredging unit can move within the discharge pipe 13 and ensure that fertilizer flows smoothly from the discharge pipe 13 into the spray pipe 14.

[0034] The unblocking unit reciprocates within the discharge pipe 13 along the axial direction of the discharge pipe 13.

[0035] The walking unit includes a rotating shaft 6 that is rotatably connected to the lower end of the fixed frame 5. Two rollers 7 are concentrically fixed on the rotating shaft 6, and a cam 16 is fixed on the rotating shaft 6 between the two rollers 7.

[0036] The unblocking unit includes a square rod 17, the lower end of which is arc-shaped. The upper end of the square rod 17 passes through the spray pipe 14 and extends into the discharge pipe 13.
