Description

Technical Field

[0001] This utility model relates to the technical field of corn fertilization equipment, specifically a quantitative fertilization device for corn planting. Background Technology

[0002] Fertilizer application is necessary during corn planting to ensure the corn receives the nutrients it needs for growth. Currently, fertilizer applicators are commonly used for fertilization during corn planting.

[0003] A search revealed that CN210671295U discloses an agricultural equidistant fertilizer applicator. Addressing the problems of uneven material discharge from the hopper and the tendency for material to clog the hopper in existing fertilizer applicators, the following solution is proposed: It includes a base plate, with a machine body on top of the base plate. Four support seats are fixedly installed at the bottom of the base plate, each with a rotating groove at its bottom. Rollers are rotatably installed within the rotating grooves. A hopper is located at the bottom of the base plate. Two support seats on the same horizontal axis have a common rotating rod, with both ends of the rod extending into corresponding rotating grooves. Rollers are rotatably installed on the corresponding rotating rod. An eccentric wheel is fixedly fitted onto the rotating rod. This invention has a simple structure, is easy to use, and can vibrate the outside of the hopper by striking it, thus accelerating the material discharge efficiency and effectively preventing hopper clogging.

[0004] While the aforementioned fertilizer applicator has achieved some success in solving the problem of funnel blockage, it still has the following limitations: First, uneven fertilizer distribution: Although the tapping mechanism promotes fertilizer fall, the tapping force and frequency may lead to uneven fertilizer fall speed, resulting in uneven distribution of fertilizer in the farmland soil and affecting the balanced absorption and growth of corn. Second, limited adjustment of feed rate: The design does not provide a fertilizer feed rate adjustment device, making it impossible to flexibly adjust the fertilizer application rate according to different soil conditions, corn growth stages, and fertilizer types, thus limiting its applicability. Third, lack of crushing function: For fertilizers that are prone to caking, the fertilizer applicator lacks a crushing device, making it impossible to effectively treat caking fertilizer before application, which may lead to poor or uneven fertilization.

[0008] The driven sprocket is connected to the drive sprocket fixedly connected to the output shaft of the drive motor via a drive chain.

[0009] Specifically, the crushing component includes a rotating shaft and several crushing paddles mounted on the rotating shaft.

[0010] Specifically, the fertilizer application assembly also includes a nut fixedly connected to the lower surface of the arc-shaped limiting plate, the nut having an internal threaded connection to a fastening screw, and the arc-shaped plate having a through hole for the fastening screw to move.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting up a crushing component, allows the crushing paddle and rotating shaft of the crushing component to rotate synchronously during operation, which can crush the clumps of fertilizer in the fertilizer bin and solve the problem of fertilizer discharge blockage from the root.

[0016] 2. This utility model, by setting an arc-shaped limiting plate, a limiting through groove, a blocking plate, a fastening nut, and a fastening screw, allows the blocking plate to slide within the limiting through groove during use, thereby adjusting the opening of the discharge port. Once the opening of the discharge port is adjusted appropriately, simply tighten the fastening screw to press the blocking plate firmly, preventing the blocking plate from shifting and providing a simple and quick adjustment of the fertilizer discharge amount.

[0017] 3. By setting a drive motor, the PID module can match different operating speeds. During operation, as long as the tractor moves forward at a constant speed, the PID module can ensure that the drive motor rotates at the set speed, thereby ensuring the uniformity of fertilization.

A drive motor 5 is installed on one side of the fertilization component 4 and on the inner side of the front of the frame to provide power to the fertilization component 4.

[0028] The fertilizer application assembly 4 includes a fertilizer box 401 fixedly connected to the inner surface of the frame 1. A feeding hopper 402 is fixedly connected to the lower end of the fertilizer box 401. An arc-shaped groove 403 is provided at the lower end of the feeding hopper 402. An arc-shaped plate 404 is fixedly connected to the outer side of the arc-shaped groove 403. A feeding wheel 405 is rotatably connected between the arc-shaped groove 403 and the arc-shaped plate 404. A discharge port 406 is provided on the arc-shaped plate 404. An arc-shaped limiting plate 407 is fixedly connected to the lower surface of one end of the arc-shaped plate 404. A blocking plate 4 adapted to the discharge port 406 is slidably connected inside the arc-shaped limiting plate 407. 08. A rotating shaft 409 is fixedly connected to the axis of the feeding wheel 405. A driven sprocket 410 is fixedly connected to the middle of the rotating shaft 409. A first sprocket 411 is fixedly connected to both ends of the rotating shaft 409. A crushing part 412 is rotatably connected inside the fertilizer box 401. A second sprocket 413 is fixedly connected to one end of the crushing part 412 through the side wall of the fertilizer box 401. The first sprocket 411 and the second sprocket 413 are connected by a chain 414. The driven sprocket 410 is connected by a drive chain 6 to a drive sprocket 7 fixedly connected to the output shaft of the drive motor 5.

[0029] The crushing component 412 includes a rotating shaft 4121 and several crushing paddles 4122 mounted on the rotating shaft 4121.

[0030] The fertilizer application component 4 also includes a nut 415 fixedly connected to the lower surface of the arc-shaped limiting plate 407. The nut 415 is internally threaded with a fastening screw 416, and the arc-shaped plate 407 has a through hole for the fastening screw 416 to move.

[0031] Among them, a receiving hopper 7 is fixedly connected to the lower surface of the arc plate 404, the lower end of the receiving hopper 8 is fixedly connected to the upper end of the guide pipe 9, and the lower end of the guide pipe 9 is fixedly connected to the feeding teeth 10.

[0032] The arc-shaped limiting plate 407 has a limiting groove 4071 that is compatible with the blocking plate 408.

[0033] The drive motor 5 can be powered by the tractor's battery.

[0034] Working principle: During operation, the drive motor 5 is started, which drives the driven sprocket 410 to rotate via the drive sprocket 7 and drive chain 6. The rotating shaft 409 rotates synchronously under the drive of the driven sprocket 410. The first sprocket 411 connected to both ends of the rotating shaft 409 is transmitted to the second sprocket 413 via the chain 414, driving the crushing part 412 to rotate. That is, the rotating shaft 4121 and the crushing paddle 4122 rotate synchronously, crushing the lumpy fertilizer in the fertilizer box 401 into uniform particles, preventing blockage during feeding. As the feeding wheel 405 rotates with the rotating shaft 409, it actuates the crushing part 412. Fertilizer flows from the hopper 402 to the discharge port 406. The blocking plate 408 slides through the limiting groove 4071 of the arc-shaped limiting plate 407, adjusting the opening of the discharge port 406 to control the amount of fertilizer falling per unit time. The fastening screw 416 and nut 415 work together to adjust and fix the blocking plate 408 to a suitable position, ensuring a stable discharge rate. The fertilizer falls into the receiving hopper 8 through the discharge port 406 and is guided to the spreading teeth 10 through the guide pipe 9. The spreading teeth 10 move through the soil as the device moves, ensuring the fertilizer is evenly distributed into the soil for precise deep application. The drive motor 5 is powered by the tractor battery and its speed is adjusted by a PID control module to match different operating speed requirements.
