Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, specifically to a wheat planting and fertilization device. Background Technology

[0002] With the development of modern agricultural industry, various agricultural machines have gradually replaced traditional manual labor, reducing labor intensity, improving field operation efficiency, and promoting the rapid development of wheat planting towards large-scale, intensive, and standardized operations.

[0003] Fertilization is a core agronomic step in wheat cultivation, directly affecting crop growth, stress resistance, and final yield and quality. Currently, wheat planting and fertilization operations are largely mechanized. Integrated sowing and fertilization machines, such as the "Combined Pneumatic Seeder (also called a row seeder) CSC6000," are widely used for planting and fertilizing field crops like wheat and corn. Their main structure includes a beam frame, feed hopper, double-disc furrow opener, and press rollers. They allow for precise control of sowing or fertilization depth, and the rubber press rollers behind the furrow opener enable simultaneous sowing, fertilization, and covering with soil.

[0004] However, in actual operation, it can be observed that the entire equipment relies on a tractor for movement, with the feed hopper moving forward synchronously with the tractor. The fertilizer falls horizontally due to inertia, while the furrow opener moves forward. During this process, the fertilizer moves backward relative to the furrow opener and the press wheel. Because the fertilizer particles are relatively light, when there is strong wind or the soil is hard, the fertilizer is easily disturbed by airflow, shifting from the furrow opener's furrow or being blown out, failing to fall accurately to the pre-applied fertilization location. This leads to decreased fertilization uniformity and reduced fertilizer utilization, affecting not only wheat emergence and subsequent growth but also hindering the realization of high-quality, high-efficiency, and precise fertilization operations. Therefore, to address the shortcomings of existing integrated sowing and fertilization equipment, it is necessary to develop a wheat planting and fertilization device with optimized structure, stable material distribution, and wind resistance to meet the needs of modern agricultural production.

[0005] To address the above problems, the present invention provides a wheat planting and fertilization device. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a wheat planting fertilization device that prevents fertilizer from splashing everywhere during fertilization and also helps to break up clumps of fertilizer.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A wheat planting fertilization device includes a feed box, a base fixedly connected to the bottom of the feed box, a pull rod fixedly connected to the base, and grooving components for preventing fertilizer splashing symmetrically fixedly connected to the side wall of the feed box. Each grooving component includes a first fixed rod, one end of which is fixedly connected to the side wall of the feed box, and the other end of which is hinged to a triangular swing arm. The side wall of the swing arm is hinged to the pull rod, and a connecting rod is hinged to the bottom of the swing arm. A fixed shaft is provided at the bottom of the connecting rod, and discs are fixedly connected to both ends of the fixed shaft. A baffle is provided at the bottom of the connecting rod, and the baffle is located between the two discs. A blocking block is hinged to the bottom of the baffle, and a wedge-shaped push block is fixedly connected to the side of the blocking block near the fixed shaft. Protrusions are symmetrically fixedly connected to the sides of the discs that are close to each other, and the push blocks are located within the movement trajectory of the protrusions. A soil covering component for assisting in leveling the soil is hinged to one end of the feed box, and a discharge component for guiding fertilizer discharge is provided inside the feed box.

[0008] The technical principles of the above solution are as follows: During operation, the entire machine is towed forward by a tractor via a pull rod. The fertilizer in the hopper is discharged in measured quantities by the discharge assembly and falls into the seed furrows pre-formed by the furrowing assembly. The furrowing assembly adopts a hinged contour-following structure. The first fixed rod connects the assembly to the side wall of the hopper. One end of the triangular swing arm is hinged to the pull rod, and the bottom is connected to the furrowing disc via a connecting rod. When the ground undulates, the swing arm can swing around the hinge point, keeping the disc in contact with the ground and ensuring consistent furrowing depth.

[0009] Two symmetrical discs roll and cut the soil under traction, forming a trapezoidal fertilizer trench. When fertilizer falls from the hopper, the baffle and blocking blocks work together to prevent fertilizer particles from splashing to both sides due to the high-speed rotation of the discs, ensuring that all fertilizer falls precisely to the bottom of the trench and avoiding spillage and waste. In addition, the baffle moves forward synchronously with the discs. As the fertilizer particles fall naturally due to gravity, the blocking blocks and fertilizer particles move relative to each other. The protrusions and push blocks on the blocking blocks work together to make the blocking blocks oscillate periodically. When clumps of fertilizer (especially hard clumps formed after absorbing moisture) hit the blocking blocks, the blocking blocks further beat the fertilizer particles during the oscillation, breaking up the clumps. The clumps of fertilizer are crushed or scraped apart, making the fertilizer more evenly distributed in the trench, which is beneficial for root absorption. The hinged structure between the blocking blocks and the baffles can effectively prevent rigid damage.

[0010] The above approach has the following beneficial effects: 1. This solution integrates anti-splashing and fertilizer crushing to improve fertilizer utilization. By placing baffles and blocking blocks between two trenching discs, fertilizer particles thrown to both sides during disc rotation are effectively blocked, ensuring all fertilizer falls to the bottom of the trench, avoiding waste. Simultaneously, the protrusions and push blocks work together to cause the blocking blocks to oscillate periodically. During this oscillation, the blocks crush or scrape apart moisture-absorbing and clump-forming fertilizer, resulting in a more even distribution of fertilizer within the trench, which is beneficial for root absorption and thus improves fertilizer efficiency.

[0011] 2. This solution features contour-following trenching and depth self-adaptation to ensure stable fertilization. The trenching component adopts a triangular swing arm hinge structure: one end of the swing arm is hinged to a fixed rod, the other end is hinged to a tie rod, and the bottom is connected to a disc via a connecting rod. When the ground surface undulates or soil resistance changes, the swing arm can automatically swing around the hinge point, keeping the disc in close contact with the ground, ensuring consistent trenching depth, avoiding over- or under-fertilization due to uneven terrain, and improving fertilization quality.

[0012] 3. In this design, the bottom blocking block of the baffle serves both anti-clogging and protective functions. The hinged blocking block at the bottom of the baffle can lightly press down on the trench bottom during trenching, further leveling the fertilizer bed. When encountering obstacles such as rocks or hard soil clods, the blocking block can swing backward to avoid them, preventing rigid impact damage to the baffle or disc. This ensures continuous operation and extends the service life of key components. Furthermore, a torsion spring is provided between the baffle and the blocking block.

[0013] Beneficial effects: By setting a torsion spring between the baffle and the blocking block, the blocking block is provided with an elastic restoring force, which allows it to automatically return to its original position after swinging backward to avoid obstacles such as stones, thus maintaining the flat and compacting effect on the bottom of the ditch, while ensuring the stable and reliable anti-splash function of the baffle.

[0014] Furthermore, the soil covering assembly includes a roller, with arc-shaped second fixing rods fixedly connected to both ends of the roller, and the other end of each second fixing rod fixedly connected to a corresponding swing arm.

[0015] Beneficial effects: The arc-shaped second fixed rod is connected to the two sides of the swing arm, which allows the roller to float adaptively with the swing arm, always maintaining good contact with the ground, achieving uniform soil covering, and the structure is simple and not easy to be blocked by soil.

[0016] Furthermore, the material discharge assembly includes a material distribution wheel, which is rotatably connected to the inner wall of the material box. The material distribution wheel is coaxially fixedly connected to a rotating wheel, which is located outside the material box. A transmission assembly for controlling the rotation of the material distribution wheel is provided on the base. A material conveying pipe is connected to the side wall of the material box and extends to the top of the corresponding fixed shaft.

[0017] Beneficial effects: The discharge assembly uses a material distribution wheel and a rotating wheel fixed on the same axis, and is driven by a transmission assembly to achieve quantitative and uniform discharge; the outlet of the conveying pipe extends to the top of the fixed shaft, so that the fertilizer falls directly into the groove between the two discs, further enhancing the anti-splashing effect of the baffle and improving the accuracy of fertilizer drop point.

[0018] Furthermore, the transmission component includes a motor, and the output end of the motor is provided with a transmission belt, which is engaged with the rotating wheel for transmission.

[0019] Beneficial effects: The transmission component adopts a motor-driven transmission belt, which ensures smooth power transmission and low noise. The amount of fertilizer discharged can be adjusted by adjusting the motor speed.

[0020] Furthermore, a monitoring component for monitoring the passage of fertilizer is installed inside the conveying pipe. A sensor is fixedly connected to the inner wall of the conveying pipe, and a controller and an alarm are installed on the base. The output end of the sensor is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input end of the alarm.

[0021] Beneficial effects: Sensors on the inner wall of the delivery pipe monitor the fertilizer flow status in real time. When blockage or interruption of fertilizer application occurs, the controller immediately triggers an alarm to alert operators and ensure timely handling, effectively preventing missed or interrupted application and guaranteeing the continuity and uniformity of fertilization. Furthermore, the base is equipped with a battery and a switch for controlling the battery's on / off state.

[0022] Beneficial effects: It provides an independent power supply for the motor and monitoring components, eliminating the need for an external tractor battery and simplifying the wiring layout; the switch facilitates power on / off, saving energy and extending equipment standby time.

[0023] Furthermore, the base is equipped with casters at the bottom.

[0024] Beneficial effects: The base is equipped with rollers, which can support the weight of the whole machine, reduce forward resistance, and facilitate short-distance transfer and transportation in the field, thus improving operational flexibility.

[0025] Furthermore, hooks are fixedly connected to the side wall of the base.

[0026] Beneficial effect: Facilitates mounting the base to a tractor.

[0027] Furthermore, a lid is detachably attached to the top of the hopper.

[0028] Beneficial effects: When opened, it facilitates quick addition of fertilizer; when closed, it effectively prevents foreign objects from falling in, fertilizer from getting damp, or dust from splashing, keeping the inside of the hopper clean and reducing fertilizer loss.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The following detailed description illustrates the specific implementation methods: Example 1:

[0035] As attached Figure 1 and Figure 3As shown: A wheat planting fertilization device includes a feed box 1, a base 2 welded to the bottom of the feed box 1, a pull rod 3 welded to the base 2, and symmetrically fixedly connected ditching components for preventing fertilizer splashing on the side walls of the feed box 1. Each ditching component includes a first fixing rod 101, one end of which is welded to the side wall of the feed box 1, and the other end of which is hinged to a triangular swing arm 5. The side wall of the swing arm 5 is hinged to the pull rod 3, and a connecting rod 6 is hinged to the bottom of the swing arm 5. A fixed shaft 7 is provided at the bottom of the connecting rod 6 (a bearing seat is welded to the bottom of the connecting rod 6, and a bearing is installed in the bearing seat; the fixed shaft 7 passes through the inner ring of the bearing). Both ends of the fixed shaft 7 are fixedly connected to discs 8, and each bottom of the connecting rod 6 is provided with a baffle 9, which is located between the two discs 8. Figure 4 As shown, a stop block 10 is hinged to the bottom of the baffle 9 (the bottom of the stop block 10 is arc-shaped and has several openings to reduce the air resistance on the side wall of the stop block 10 when the disc 8 moves). A push block 201 is fixedly connected to the side of the stop block 10 near the fixed shaft 7. A protrusion 202 is symmetrically welded to the side of the disc 8 that is close to each other. The push block 201 is located within the movement trajectory of the protrusion 202. A torsion spring 11 is provided between the baffle 9 and the stop block 10. The number of grooved components can be adjusted according to the actual situation.

[0036] One end of the material box 1 is hinged to a soil covering component for assisting in leveling the soil. The soil covering component includes a roller 12, and both ends of the roller 12 are fixedly connected to an arc-shaped second fixing rod 102. The other end of the second fixing rod 102 is welded to the corresponding swing arm 5. The material box 1 is provided with a discharge component to guide the fertilizer discharge.

[0037] The specific implementation process is as follows: During operation, the tractor pulls the base 2 forward via the pull rod 3. The fertilizer in the feed box 1 is discharged quantitatively by the discharge assembly and falls into the seed trench pre-formed by the trenching assembly. The first fixed rod 101 connects the trenching assembly to the side wall of the feed box 1. The side wall of the triangular swing arm 5 is hinged to the pull rod 3, and the bottom is connected to the trenching disc 8 via the connecting rod 6. When the ground undulates, the swing arm 5 can swing around the hinge point, so that the disc 8 always keeps in contact with the ground and ensures that the trenching depth is consistent.

[0038] Two symmetrical discs 8 roll and cut the soil under traction, forming a trapezoidal fertilizer trench. When fertilizer falls from the hopper 1, it falls due to inertia. Fertilizer particles are splashed onto the baffle 9 and the blocking block 10 due to wind force. The baffle 9 and the blocking block 10 work together to block fertilizer particles that are splashed to both sides due to the high-speed rotation of the discs 8, ensuring that all fertilizer falls accurately to the bottom of the trench, avoiding spillage and waste. At the same time, the protrusion 202 rotates with the discs 8, and the protrusion 202 regularly collides with the push block 201 on the blocking block 10. Since the baffle 9 and the blocking block 10 are hinged, when the protrusion 202 collides with the push block 201, the protrusion 202 pushes the blocking block 201. When the protrusion 202 rotates to a position away from the baffle 9, the block 10 is reset by the restoring force of the torsion spring 11. As the baffle 9 moves forward synchronously with the disc 8, the fertilizer particles fall naturally under gravity. The block 10 and the fertilizer particles move relative to each other. During the periodic swing, the block 10 collides with the clumps of fertilizer (especially the hard clumps formed after absorbing moisture). During the collision, the clumps of fertilizer are crushed or scraped, making the fertilizer more evenly distributed in the trench, which is beneficial to root absorption.

[0039] In addition, the torsion spring 11 provides elastic restoring force to the block 10, allowing it to automatically return to its original position after swinging backward to avoid obstacles such as stones, thus maintaining the flatness of the trench bottom and ensuring the stable and reliable anti-splash function of the baffle 9. After the fertilizer falls into the trench, the roller 12 at the rear backfills and lightly compacts the soil. The arc-shaped second fixing rod 102 is connected to the swing arms 5 on both sides, allowing the roller 12 to float adaptively with the swing arms 5, always maintaining good contact with the ground, achieving uniform soil coverage, and completing the fertilization operation with a simple structure.

[0040] Because the gaps between the discs 8 in traditional furrow openers are relatively large, fertilizer is easily splashed everywhere or even blown out of the furrow due to wind, reducing fertilizer utilization. In this design, the articulated block 10 at the bottom of the baffle 9 has a dual function: firstly, it gently presses down on the furrow bottom during furrowing to further level the fertilizer bed; secondly, the protrusion 202 cooperates with the push block 201 on the block 10 to cause the block 10 to oscillate periodically. When clumps of fertilizer are impacted by inertia onto the block 10, the block 10 periodically strikes the fertilizer particles during its oscillation, further breaking up the clumps. The articulated structure between the block 10 and the baffle 9 effectively prevents rigid damage. This design achieves multi-functional integration of anti-splashing, fertilizer clumping breaking, and depth adaptive functions.

[0041] Example 2:

[0042] As attached Figure 2As shown, the difference from Embodiment 1 is that the material discharge assembly includes a material distribution wheel 13 (the surface of the material distribution wheel 13 is provided with grooves), the material distribution wheel 13 is rotatably connected to the inner wall of the material box 1, and a rotating wheel 14 is coaxially welded and fixed to the material distribution wheel 13. The rotating wheel 14 is located outside the material box 1, and a transmission assembly for controlling the rotation of the material distribution wheel 13 is provided on the base 2. The transmission assembly includes a motor 16, and a transmission belt 17 is provided at the output end of the motor 16. The transmission belt 17 is in transmission cooperation with the rotating wheel 14.

[0043] A feed pipe 15 is connected to the side wall of the feed hopper 1, extending above the corresponding fixed shaft 7 (a fixing ring is installed on the pull rod 3, and the middle section of the feed pipe 15 is fixed to the pull rod 3 by the fixing ring). A monitoring component for monitoring fertilizer passage is installed inside the feed pipe 15. A sensor 18 is fixedly connected to the inner wall of the feed pipe 15. The preferred model of the sensor 18 is an IMS-CX90150 frame-type photoelectric sensor. A controller 19 and an alarm 20 are installed on the base 2. The preferred model of the controller 19 is an SPC-SFMC-X2214A controller, and the preferred model of the alarm 20 is a BC-809 audible and visual alarm. The output terminal of the sensor 18 is electrically connected to the input terminal of the controller 19, and the output terminal of the controller 19 is electrically connected to the input terminal of the alarm 20. A battery 21 and a switch for controlling the opening and closing of the battery 21 are installed on the base 2.

[0044] The specific implementation process is as follows: During fertilization, the motor 16 is started, and the output end of the motor 16 rotates, driving the transmission belt 17 sleeved on the output end to move. The other end of the transmission belt 17 and the rotating wheel 14 (located outside the material box 1) coaxial with the distributing wheel 13 form a belt drive pair. The rotating wheel 14 rotates with the transmission belt 17, thereby driving the distributing wheel 13 to rotate around its own axis inside the material box 1. When the distributing wheel 13 rotates, the fertilizer particles in the material box 1 fall into the groove of the distributing wheel 13 under the action of gravity. The fertilizer particles are forced out of the outlet at the bottom of the material box 1 as the distributing wheel 13 rotates and enter the conveying pipe 15 which is connected to the side wall of the material box 1.

[0045] After entering the conveying pipe 15, the fertilizer slides down the pipe wall under the influence of gravity. The outlet end of the conveying pipe 15 extends directly above the corresponding fixed shaft 7 (i.e., the shaft between the two trenching discs 8). Therefore, when the fertilizer leaves the pipe, it has a forward inertial component and falls into the center of the trench created by the two discs 8 with an approximately projectile trajectory. During this process, the baffle 9 (located between the two discs 8) further prevents the fertilizer from splashing to both sides, ensuring that all the fertilizer falls to the bottom of the trench. As the fertilizer slides down the conveying pipe 15, the sensor 18 fixed to the inner wall of the conveying pipe 15 detects in real time whether fertilizer is passing through. If the sensor 18 does not detect fertilizer passing through for a period of time (e.g., the distributor wheel 13 is stuck, the conveying pipe 15 is blocked, or the fertilizer is used up), the controller 19 determines that there is a "fertilizer shortage" or "blockage" and immediately sends a trigger signal to the alarm 20. The alarm 20 issues an audible and visual alarm to remind the operator to troubleshoot the problem in time.

[0046] Example 3:

[0047] As attached Figure 1 As shown, the difference from Embodiment 2 is that, in addition, considering the convenience of field operation and transportation, an auxiliary support and movement structure is provided. The bottom of the base 2 is provided with a roller 22 (the roller 22 is a universal wheel with a brake), and a hook 23 is fixedly connected to the side wall of the base 2. The top of the material box 1 is detachably connected to a cover 4 by a latch (a sealing ring is provided between the cover 4 and the material box 1).

[0048] The specific implementation process is as follows: Considering the convenience and stability of field operations, auxiliary support and movable structures are added. Rollers 22 provide the main support for the material box 1 when towed by a tractor. At the same time, rollers 22 reduce forward resistance, facilitating short-distance transport in the field and improving operational flexibility. Hooks 23 allow the base 2 to be suspended from the tractor. The detachable cover 4 on the top of the material box 1 is made of transparent polycarbonate for easy observation of the material level. A sealing ring is provided between the cover and the material box 1, effectively preventing rainwater, dust, and weed seeds from falling in, keeping the fertilizer dry and clean. The cover 4 also features a push-button lock and a handle, allowing for one-handed opening and closing.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
