Description

Technical Field

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

[0002] During the planting and growth of rice, fertilization is necessary. Nitrogen, phosphorus, potassium, and micronutrient fertilizers must be added appropriately to ensure the rice receives the necessary nutrients. Proper fertilization promotes rice growth. Generally, fertilization is done at the same time as rice sowing. During the subsequent growth process, topdressing is required based on the actual growth conditions. Traditional topdressing involves manually spreading fertilizer by hand, which is inefficient.

[0003] Chinese patent application number CN202221737780.4 discloses a rice planting fertilization device, including a box shell. Fixed plates are fixed to the front and rear sides of the box shell, and a bottom plate is fixed to the bottom of the fixed plates. A motor is fixed to the top of the inner cavity of the box shell, and a stirring shaft is fixed to the output shaft of the motor. The bottom of the stirring shaft extends through to and is movably connected to the bottom of the box shell. A bearing seat is fixed to the bottom of the stirring shaft, and the other end of the bearing seat is fixed to the top of the bottom plate. This device can adjust the discharge speed, increasing fertilization efficiency. However, when adding fertilizer, the rice growth height varies at different stages, and the discharge height needs to be adjusted according to the rice height for more even fertilization. Unfortunately, this device cannot adjust the discharge height, making it inconvenient to use.

[0004] Based on this, the present invention designs an adjustable rice topdressing device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable rice topdressing device.

[0007] An adjustable rice topdressing device includes an adjusting plate and a fertilizer bucket. A shoulder strap is fixed to one side of the adjusting plate, and handles are symmetrically fixed to both sides of the adjusting plate. A discharge port is opened at the bottom of the side wall of the fertilizer bucket, and a feed port is opened at the top of the fertilizer bucket. A discharge plate is rotatably opened at the bottom of the inner cavity of the fertilizer bucket, and a dividing strip is fixed at the top of the discharge plate. A sliding groove is opened at the center of the side of the adjusting plate, and a slider slides in the sliding groove. The fertilizer bucket is fixed on the slider. A positioning hole is opened on the slider and the sliding groove, and a positioning rod is threaded into the positioning hole.

[0008] Furthermore, the top of the discharge plate and the bottom of the discharge port are located on the same horizontal plane, the separator is evenly fixed on the discharge plate, the chute is provided through the top and bottom of the adjustment plate, and the positioning holes on the chute are provided at equal intervals.

[0009] Furthermore, it also includes a stirring component, which includes a motor, a filter screen, a rotating rod, and a dispersing rod. The motor is installed at the top of the inner cavity of the fertilizer tank, the filter screen is movable on the inner wall of the fertilizer tank, the rotating rod is installed at the output end of the motor and rotates through the filter screen, one end of the rotating rod is connected to the discharge plate, and the dispersing rod is fixed on the part of the rotating rod located above the filter screen.

[0010] Furthermore, the filter screen is positioned on the central plate of the fertilizer tank, and the discharge disc is threadedly fixed to the bottom end of the rotating rod.

[0011] Furthermore, the top of the fertilizer tank is threaded with a lid, the discharge port is located on the lid, the motor is mounted on the top of the lid and an isolation frame is provided on the outside, and the isolation frame is threadedly fixed to the top of the lid.

[0012] Furthermore, an adjusting component is installed on the discharge port. The adjusting component includes a bottom groove, a top groove, a mounting groove, and a dividing rod. The bottom groove and the top groove are symmetrically arranged at the upper and lower ends of the discharge port. The mounting groove is connected to the top groove and passes through the fertilizer tank. The dividing rod moves between the bottom groove and the top groove.

[0013] Furthermore, the bottom trough is installed through the side of the fertilizer bucket, and the length of the dividing rod is equal to the maximum vertical distance from the bottom trough to the top trough, while the length of the dividing rod is less than the maximum vertical distance from the bottom trough to the installation groove.

[0014] Furthermore, the bottom groove is provided with uniformly spaced positioning grooves, the depth of which is less than the depth of the top groove.

[0015] Beneficial effects

[0016] 1. By setting up a chute, slider, positioning hole and positioning rod, when applying fertilizer to rice, the position of the slider can be adjusted according to the specific height of the rice growth. The slider is fixed by the threaded engagement of the positioning rod and the positioning hole, thereby realizing the adjustment of the height of the discharge port at the bottom of the fertilizer tank, which is convenient for applying fertilizer.

[0017] 2. By incorporating a stirring component, during topdressing, the motor drives the rotating rod to break up the falling fertilizer using a dispersing rod, preventing clumping. The broken fertilizer falls through a filter screen onto the discharge plate, where the rotating rod drives the discharge plate to rotate, using centrifugal force to fling the fertilizer out for easy discharge. By incorporating an adjusting component, when adjustments are needed, an appropriate number of dividing rods can be removed and movably installed between the bottom and top troughs from the mounting slot, and fixed using the positioning slot. The dividing rods act as barriers, allowing for adjustment of the fertilizer application rate. By incorporating a bucket lid, the stirring component is mounted on the lid, facilitating its installation and removal inside the fertilizer bucket. Attached Figure Description
