Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a fertilization device used in the potato planting process. Background Technology

[0002] Potatoes, also known as spuds or yams, are annual herbaceous plants belonging to the Solanaceae family and the Solanum genus. Their tubers are the world's fourth most important food crop, after wheat, rice, and corn. Originally from the Andes Mountains of South America, they are now widely cultivated around the world. They adapt to various climates and soil conditions, are particularly cold- and drought-resistant, and are relatively easy to grow and manage. They can be eaten as a staple food by steaming, boiling, or baking, or they can be made into a variety of dishes by frying, deep-frying, and stir-frying. They can also be processed into starch, potato chips, and French fries, possessing multiple values ​​as a food, vegetable, and industrial raw material. As a high-yield crop, they play a key role in ensuring global food security and are an important part of the agricultural economy in many regions.

[0003] Fertilization devices used in potato cultivation are specialized agricultural equipment that combines agricultural machinery design, precision fertilization concepts, and automated control technology. They enable quantitative, targeted, and efficient fertilization based on potato growth characteristics and soil fertility. Existing fertilization devices control fertilizer discharge by setting an adjustable gate in the fertilizer drop channel and changing the gate opening size. However, once the gate opening size is manually set, it remains fixed and cannot be automatically adjusted according to the machine's forward speed or terrain undulations. Current technology involves adding chains and gear sets to the traveling wheels (or drive wheels) and connecting them to transmission components. A connecting rod connects to the gate lever; when the cam rotates, it pushes the connecting rod, which in turn moves the gate lever, controlling the gate opening size according to the traveling wheel speed. However, mechanical gaps exist in the gear meshing, chain-sprocket engagement, and connecting rod joints. When the traveling wheel speed changes, the gear set must first eliminate these gaps before driving the cam, causing the gate opening adjustment to lag behind the actual speed change. This results in insufficient nutrients in certain areas, leading to slow seedling growth, restricted tuber enlargement, and ultimately reduced yield. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fertilization device for potato planting, aiming to improve the mechanical gaps in the existing technology, such as gear meshing, chain and sprocket meshing, and connecting rod joints. When the speed of the traveling wheel changes, the gear set must first eliminate the gaps before driving the cam to rotate, causing the gate opening adjustment to lag behind the actual speed change, resulting in insufficient local nutrients, slow seedling growth, restricted tuber enlargement, and ultimately reduced yield.

Specifically, when servo motor 3041 is turned on, its output drives the transmission shaft 3042 to rotate, which in turn drives the helical gear 3043 on its outer wall to rotate. The transmission shaft 3042 can rotate at the right end of the protective cover 3048, reducing the offset during rotation and providing stable support for rotation. Through the meshing of the helical gear 3043 and the helical rack 303, the helical rack 303 slides vertically inside the front end of the load-bearing plate 1 to adjust its position. Since the helical rack 303 drives the trenching shovel 301 to move through the connecting block 302, the trenching shovel...

Each load-bearing column 6 is equipped with casters 7 at the bottom, allowing the equipment to turn flexibly. The bottom rear end of the outer wall of the load-bearing plate 1 has limit plates 8 on the left and right sides. The bottom end of the limit plates 8 has rollers 9 inside. The rollers 9 can push the soil into the fertilization trench after fertilization to fill it and reduce fertilizer loss. The top of the outer wall of the load-bearing plate 1 has a fertilizer storage box 10, which can be opened with a handle 11 for storing fertilizer. Through the coordinated work of various components, the equipment's mobility and fertilizer storage function are ensured.

[0021] Working principle: When the servo motor 2041 is turned on, its output end can drive the worm gear 2042 to rotate. Through the meshing of the worm gear 2042 and the worm wheel 2043, the worm wheel 2043 drives the rotating shaft 202 to rotate in the middle of the fertilizer outlet trough 201. This, in turn, drives the multiple rotating plates 203 welded to the outer wall of the rotating shaft 202 to rotate together. The protective cover 2044 protects the servo motor 2041 and the transmission components. Its top is fixed to the bottom of the load-bearing plate 1. The right end of the fertilizer outlet trough 201 is connected to the left end of the protective cover 2044 to ensure the stable operation of the entire mechanism. By adjusting the rotation speed of the rotating plates 203, the amount of fertilizer passing through the fertilizer outlet trough 201 can be changed, thereby controlling the amount of fertilizer discharged. When the servo motor 3041 is turned on, its output drives the transmission shaft 3042 to rotate, which in turn drives the helical gear 3043 welded to its outer wall to rotate. The transmission shaft 3042 can rotate at the right end of the protective cover 3048, providing stable support for the rotation. Through the meshing of the helical gear 3043 and the helical rack 303, the helical rack 303 slides vertically inside the front end of the load-bearing plate 1. Since the helical rack 303 drives the trenching shovel 301 to move through the connecting block 302, the height of the trenching shovel 301 can be adjusted. The ratchet 3044 and pawl 3045 on the right side of the outer wall of the transmission shaft 3042 cooperate to restrict the reverse rotation of the transmission shaft 3042. The pull rod 3047 can slide in the slide groove 3049 on the right side of the top of the protective cover 3048. Pulling the pull rod 3047 will disengage the pawl 3045 from the ratchet 3044 and adjust the height of the trenching shovel 301, so as to dig fertilization trenches of different depths as needed.
