Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to a fertilization device for agricultural planting. Background Technology

[0002] In agricultural planting, the uniformity and precision of fertilization operations directly affect crop yield and soil sustainability. Traditional fertilization devices mostly use mechanical vibration to drive the feeding, achieving fertilizer spreading through the cooperation of a distribution plate and a discharge port. With the development of precision agriculture technology, the industry has placed higher demands on the dynamic adjustment capabilities, anti-interference performance, and adaptability to multiple scenarios of fertilization devices. Especially when dealing with complex terrain and diverse crop planting patterns, key technical issues such as vibration interference compensation and rapid adjustment of discharge parameters need to be addressed.

[0003] However, existing agricultural fertilization devices typically rely on fixed-frequency vibrators to drive the feeding, which cannot compensate for the mechanical vibrations and density fluctuations caused by material adhesion during the operation of the traction equipment. This results in uneven distribution of fertilizer in the spreading and discharging trays, with localized accumulation or material shortages, leading to uneven fertilization of crops and affecting yield consistency. Furthermore, parameters such as discharging interval and feeding flow rate are mostly adjusted by replacing parts, lacking modular and rapid adjustment designs (such as detachable blocking blocks and screw-driven connecting screws). This makes it difficult to adapt to the dynamic needs of different crop row spacings, soil moisture, and terrain undulations, limiting the application scenarios of the same device and resulting in low operating efficiency.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A fertilizer applicator for agricultural planting includes a diagonal support rod 101. A mounting plate 102 is fixedly installed on one side of the diagonal support rod 101. The mounting plate 102 has a mounting hole 103. A fertilizer applicator 104 is provided on the side of the diagonal support rod 101 away from the mounting plate 102. The fertilizer applicator 104 includes a storage box 105 and a sensor head 203. A connecting plate 106 is fixedly installed at the bottom of the storage box 105. A connecting screw 201 is screwed onto the connecting plate 106. A feeding trough 202 is provided at the bottom of the inside of the storage box 105. A connecting wire 204 is fixedly installed on one side of the sensor head 203. A sensor controller 205 is fixedly installed on the side of the connecting wire 204 away from the sensor head 203.

[0023] The above scheme uses a combination of diagonal braces and mounting plates to fix the fertilizer applicator to the traction equipment. The storage bin guides the fertilizer through a discharge trough, and the connecting screw fixes the relative position of the storage bin and the fertilizer applicator. The sensor head forms a signal transmission path with the sensor controller through a connecting line to achieve real-time monitoring of the fertilizer falling density.

[0024] In this embodiment, preferably, the fertilization mechanism 104 further includes a fertilizer box 206, the top of the fertilizer box 206 is provided with a discharge port 301, a connecting plate 106 is fixedly installed on the top of the fertilizer box 206 near the discharge port 301, and a diagonal brace 101 is fixedly installed on the side of the fertilizer box 206 away from the connecting plate 106.

[0025] The above solution utilizes a discharge port at the top of the fertilizer box to receive fertilizer falling from the storage box; the secondary fixation of the connecting plate and the diagonal brace enhances the structural stability between the fertilizer box and the traction equipment, preventing component displacement due to vibration during operation.

[0026] In this embodiment, preferably, the fertilizer box 206 has a discharge port 302 on the side away from the diagonal support rod 101, a discharge plate 303 is movably installed in the discharge port 302, a baffle 304 is fixedly installed at the top of the discharge plate 303, and a vibration spring 305 is fixedly installed at the bottom of the discharge plate 303.

[0027] The above scheme utilizes a movable discharge tray design at the discharge port to dynamically adjust the fertilizer discharge volume; baffles form a diversion channel on the discharge tray to achieve directional distribution of fertilizer; and vibration springs absorb external vibration interference through elastic deformation, maintaining the working stability of the discharge tray.

[0028] In this embodiment, preferably, the vibration spring 305 is fixedly installed on the top of the partition plate 306, the partition plate 306 is fixedly installed inside the fertilizer box 206, and the first vibrator 401 is fixedly installed on the side of the discharge tray 303 near the vibration spring 305.

[0029] The above scheme uses a partition plate to fix and support the vibration spring, which in turn transmits vibration energy. The first vibrator drives the vibration spring to generate high-frequency micro-amplitude vibration, which promotes continuous and uniform discharge of fertilizer from the discharge plate and prevents fertilizer from accumulating and clogging at the discharge port.

[0030] In this embodiment, preferably, a hopper 402 is fixedly installed inside the fertilizer box 206 near the discharge port 301, a second vibrator 403 is fixedly installed on one side of the hopper 402, and a connecting rod 404 is fixedly installed on the side of the hopper 402 near the second vibrator 403.

[0031] The above scheme uses the inclined guide surface of the hopper to guide the fertilizer from the storage box to the spreading tray; the second vibrator drives the hopper to vibrate to prevent the fertilizer from sticking; the limiting plate ensures that the vibration amplitude of the spreading tray is controllable by restricting the displacement range of the connecting rod.

[0032] In this embodiment, preferably, a limiting plate 405 is fixedly installed at the bottom end of the connecting rod 404, a support spring 406 is fixedly installed at the top end of the limiting rod, a spreading plate 501 is fixedly installed at the top end of the support spring 406, and a third vibrator 502 is fixedly installed on the spreading plate 501 near the support spring 406.

[0033] Through the above scheme, the elastic vibration transmission structure of the supporting spring effectively transmits the driving force of the third vibrator to the spreading disc, enabling the spreading disc to generate multi-dimensional vibration to achieve uniform fertilizer spreading; the limiting plate precisely fixes the supporting spring to the connecting rod through rigid constraint, ensuring that the vibration energy is transmitted along the predetermined path and preventing the spring from deviating and failing; under the coordinated drive of the third vibrator and the supporting spring, the spreading disc forms a stable vibration mode, ultimately achieving secondary fine distribution of fertilizer before discharge.

[0034] In this embodiment of an agricultural fertilization device, the user fixes the mounting plate 102 to the traction equipment through the mounting hole 103 and completes the assembly and fixation using the diagonal brace 101. Then, fertilizer is injected into the storage bin 105, and the device is driven to the farmland area by the traction equipment. When fertilization begins, the device is connected to the traction equipment and powered on. At this time, the third vibrator 502 starts first and drives the discharge hopper 402 to vibrate, causing the fertilizer in the storage bin 105 to fall through the discharge trough 202 into the spreading tray 501. Then, under the action of the second vibrator 403, the spreading tray 501 reciprocates through the support spring 406, evenly spreading the fertilizer onto the surface of the discharge tray 303. Finally, the first vibrator 401 drives the discharge tray 303 to vibrate axially along the vibration spring 305, causing the fertilizer to be diverted by the baffle 304 and evenly discharged onto the field. During material discharge, the sensor head 203 (infrared reflective sensor) continuously emits an infrared beam and receives the reflected signal from the material. If the vibration of the traction equipment causes uneven fertilizer density, the sensor head 203 will generate an electrical signal in real time and transmit it to the sensor controller 205 (embedded microcontroller) through the connecting line 204. After the sensor controller 205 extracts the effective density feature value through the built-in filtering algorithm, it sends frequency adjustment commands to the first vibrator 401, the second vibrator 403 and the third vibrator 502 through the connecting wires between them, thereby dynamically correcting the amplitude and frequency of each vibration component to ensure that the fertilizer density is maintained within the set threshold range. In addition, when it is necessary to expand the fertilizer discharge interval, the user can insert a detachable blocking block between the baffles 304 to change the width of the diversion path through mechanical limiting to achieve interval control.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
