A fertilizer dispenser typically consists of a power unit, transmission system, fertilizing device, control system, and travel mechanism. Depending on the application method, fertilizer dispensers can be categorized as broadcast, deep, and drip. Using a fertilizer dispenser improves fertilization efficiency, reduces labor intensity for farmers, and reduces fertilizer waste, contributing to the sustainable development of agricultural production.

DETAILED DESCRIPTION

[0023] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

The stirring structure 1 includes a stirring box 101 and a box cover 102. The upper surface of the stirring box 101 is installed with the box cover 102. One end of the upper surface of the box cover 102 is installed with the quantitative structure 3. The quantitative structure 3 includes a storage hopper 307 and a rotating disk 304. The storage hopper 307 is installed at one end of the upper surface of the box cover 102. The rotating disk 304 is rotatably connected between the storage hopper 307 and the box cover 102. One end of the upper surface of the box cover 102 is fixedly connected to a servo motor 302 through a connecting structure 301. The rotating disk 304 is connected to the servo motor 304 through a transmission rod 303. 02, the output end can control the servo motor 302 to drive the transmission rod 303 and the rotating disk 304 to rotate one circle, so as to achieve the purpose of overlapping the first feeding port 305 and the second feeding port 306 once, thereby achieving the purpose of quantitative fertilization. The surface of the rotating disk 304 is penetrated by a first feeding port 305, and the surface of the box cover 102 is penetrated by a second feeding port 306. When the first feeding port 305 and the second feeding port 306 overlap or partially overlap with each other, the fertilizer in the storage hopper 307 will fall into the overlapping part of the first feeding port 305 and the second feeding port 306 to the inside of the mixing box 101 and mix with water, which is convenient for the subsequent fertilization process.

[0025] Embodiment 1: An adjustment structure 4 is installed at one end of the lower surface of the box cover 102, and the adjustment structure 4 includes an adjustment groove 401 and a baffle 402. The adjustment groove 401 is opened on the lower surface of the box cover 102 near the second feeding port 306, and the baffle 402 is slidably connected to the inside of the adjustment groove 401. A spring structure 406 is provided between one side surface of the baffle 402 and the inner wall of the adjustment groove 401. An adjustment rod 403 is threadedly connected to the outer surface of the adjustment groove 401, and a turning handle 405 is fixedly connected to the outer end of the adjustment rod 403, and a top block 404 is fixedly connected to the inner end of the adjustment rod 403. When it is necessary to reduce the amount of fertilizer added, the turning handle 405 can be manually rotated to move the threaded rod toward the baffle 402, and the threaded rod passes through The top block 404 squeezes the baffle 402 toward the inside of the adjustment groove 401. At this time, the spring structure 406 is in a compressed state, and the second feed port 306 is partially blocked by the baffle 402, so as to achieve the purpose of accurately controlling and reducing the amount of fertilizer. When the amount of quantitative fertilizer addition needs to be increased, the threaded rod is moved in the opposite direction of the baffle 402. After the squeezing force of the top block 404 is lost, the baffle 402 is pushed outward due to the reset elastic force of the spring structure 406, thereby enlarging the area of ​​the second feed port 306, so as to achieve the purpose of accurately controlling and increasing the amount of fertilizer, realize simple and fast quantitative adjustment, and improve the precise control ability of the fertilizer machine to increase the amount of fertilizer. This design optimizes the user operation experience while ensuring the uniformity and efficiency of fertilization.

[0026] Example 2: The first feeding port 305 and the second feeding port 306 have the same shape and size. An observation window 106 is installed on the side surface of the mixing box 101, which is convenient for directly observing the mixing process and fertilizing process inside the mixing box 101 through the observation window 106. The middle part of the upper surface of the box cover 102 is fixedly connected to the driving motor 103, and the output end of the driving motor 103 is transmission-connected to the transmission shaft 104. The side surface of the transmission shaft 104 is fixedly connected to a number of stirring blades 105. The stirring blades 105 and the transmission shaft 104 are both arranged inside the mixing box 101. The driving motor 103 drives the transmission shaft 104 and the stirring blades 105 to rotate, and the fertilizer and water inside the mixing box 101 are fully stirred and mixed. The lower end of the mixing box 101 is installed with a fertilizing structure 2, and the fertilizing structure 2 includes a discharge pipe 201 and a valve 202. The discharge pipe 201 is installed at the lower end of the mixing box 101, and the surface of the discharge pipe 201 is installed with a valve 202.

[0027] When using the automatic fertilizer adding device of the fertilizer machine, first open the storage hopper 307 and pour fertilizer into it. The fertilizer falls downward under the action of gravity. Next, start the servo motor 302. Through the rotation of the transmission rod 303 and the rotating disk 304, a first feed inlet 305 is provided on the rotating disk 304, and a second feed inlet 306 is also provided on the corresponding box cover 102. When the rotating disk 304 rotates until the first feed inlet 305 and the second feed inlet 306 overlap, the fertilizer in the storage hopper 307 falls into the mixing box 101 through these two overlapping feed inlets. The servo motor 302 drives the rotating disk 304 to rotate at a constant speed. When the first feed inlet 305 moves away from the second feed inlet 306, the first feed inlet 305 is closed. At this time, the fertilizer inside the storage hopper 307 is blocked and cannot continue to fall, achieving the purpose of quantitative fertilizer addition. To adjust the amount of fertilizer applied, manually turn the handle 405. Through the interaction of the threaded rod, top block 404, and spring structure 406, the baffle 402 is squeezed or released, partially blocking or enlarging the second feed inlet 306, achieving precise control of the amount of fertilizer applied. Inside the mixing box 101, the drive motor 103 rotates the drive shaft 104 and stirring blades 105, thoroughly mixing the fertilizer and water. Finally, the valve 202 on the discharge pipe 201 is opened, and the evenly mixed fertilizer is applied to the farmland. The entire process is simple and efficient, ensuring uniform and efficient fertilization.
