Description

Technical Field

[0001] This utility model relates to the field of fertilizer application devices for agronomists, and more particularly to a quantitative fertilizer application device for agronomists. Background Technology

[0002] The quantitative fertilization device can be applied to various planting areas such as farmland, orchards, and vegetable greenhouses. It is suitable for fertilization operations during the growing season of various crops and cash crops. By applying fertilizer in a quantitative manner, it can improve fertilizer utilization, reduce resource waste, and ensure a stable supply of nutrients required for plant growth.

[0003] Traditional fertilization methods involve digging suitable pits in the soil according to the plant growth spacing, then having operators directly grab granular or powdered fertilizer by hand and put it into the pits, finally covering the pits with soil. The chemical components in the fertilizer come into direct contact with the skin of the hands, which can lead to dry skin, redness, peeling, or even chemical burns after prolonged work, damaging the operator's skin health. The amount of fertilizer applied by hand is entirely dependent on experience and cannot be precisely measured, resulting in uneven application and soil pollution or root burn due to excessive fertilizer.

[0004] In existing technologies, quantitative fertilizer application devices consisting of a loading box, a hose, and a discharge rod pre-load fertilizer into the loading box, which is connected to the discharge rod via a hose. A lever on the discharge rod controls fertilizer flow. The operator holds the discharge rod, aligns it with the pit, and pulls the lever. Under gravity, the fertilizer in the loading box flows through the hose to the discharge port of the discharge rod, dispensing the fertilizer. Releasing the lever closes the fertilizer flow channel and stops dispensing. However, in actual long-term operation, new problems arise. Opening and closing the lever relies entirely on manual operation. The operator must continuously exert force to pull the lever to control fertilizer dispensing. After prolonged operation, hand muscles become fatigued and sore, leading to unstable control of the lever and inaccurate quantitative fertilizer application. Utility Model Content

The bottom of the discharge port 18 has a discharge pipe 19 that allows the fertilizer to fall near the plants that need fertilization by gravity.

[0023] Working principle: During fertilization, the mobile power supply 11 supplies power to the system, triggering motor 201 to operate. Motor 201, as the power source, directly drives the connected bevel gear 202 to rotate. Utilizing the vertical steering characteristic of bevel gear meshing transmission, bevel gear 202 drives the meshing bevel gear 203 to rotate synchronously. Since bevel gear 203 is fixedly connected to support rod 204, power is transmitted to support rod 204, enabling it to achieve a stable speed. During this process, the fixed frame 205 provides rigid support to support rod 204, strictly limiting its radial offset and avoiding transmission errors caused by component shaking during long-term operation. Support rod 204 drives turntable 206 to rotate. 6. The rotating disk 206 rotates along a fixed path in the rotating groove 209 at the top of the feeding bucket 1. The rotating groove 209 further constrains the movement trajectory of the rotating disk 206. The limiting groove 207 on the rotating disk 206 continuously fixes the position of the mixing bucket 301. When the rotating disk 206 drives the feeding hole 208 to rotate to the bottom of the mixing bucket 301, the fertilizer will fall into the discharge port 18 along the feeding hole 208. When it is necessary to adjust the feeding speed, the speed of the motor 201 is adjusted by the controller 12. When the speed increases, the rotating disk 206 rotates faster, the alignment frequency of the feeding hole 208 and the mixing bucket 301 per unit time increases, and the feeding speed increases. When the speed decreases, the feeding speed also decreases, thereby realizing adjustable quantitative fertilization. Furthermore, fertilizer enters the mixing tank 301 through the feed inlet 5. To prevent fertilizer from clumping and blocking the discharge pipe 19 due to improper storage, the motor 302 is started, driving the connected rotating shaft 303 to rotate at high speed. The blades 304 on the rotating shaft 303 rotate synchronously, using the cutting action of the blades 304 to crush the clumped fertilizer. While the clumps are being crushed, the rotating shaft 303 also drives the rotating rod 305 to rotate synchronously. The scraper 306 at the end of the rotating rod 305 rotates in close contact with the inner wall of the mixing tank 301. The scraper 306 can clean the powder remaining on the inner wall surface of the mixing tank 301. After mixing, the fertilizer falls into the discharge port 18 through the discharge hole 208 at the bottom of the mixing tank 301. The fertilizer rolls out of the discharge pipe 19 naturally by its own gravity. In addition, the support plate 9 at the bottom of the device and the universal wheels 10 can move the entire fertilization device, effectively solving the problem of clumping and blockage in traditional fertilization.
