Description

Technical Field

[0001] This invention relates to a fertilization device, and more specifically, a strong-push type side-deep fertilization device for rice. Background Technology

[0002] Side-deep fertilization in rice cultivation is a key agronomic measure to increase rice yield and improve fertilizer utilization. Its core requirement is to precisely apply fertilizer to the deep soil layer beside the rice roots, preventing fertilizer exposure and volatilization or runoff with water. However, existing rice fertilization devices still have many shortcomings in practical applications: traditional devices often rely on the fertilizer's own gravity or simple pushing structures, making it difficult to stably deliver fertilizer to the depth required for side-deep fertilization, often resulting in shallow burial of fertilizer, which hinders full absorption by the rice roots and leads to low fertilizer utilization. Rice-specific fertilizers are mostly granular or powdered, and are prone to clumping during storage and transportation due to moisture and compression. Existing devices lack effective anti-caking and unblocking structures, easily causing blockages in the fertilizer delivery channels, affecting the continuity and uniformity of fertilization. Therefore, there is an urgent need for a high-efficiency fertilization device that can achieve deep, precise fertilization to meet the needs of modern rice cultivation. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a strong-push rice side-deep fertilization device, which has the advantages of being able to deliver fertilizer to a deeper position and make the fertilizer more dispersed in the soil by blowing air.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A powerful push-type side-deep fertilization device for rice includes a fertilizer discharge pipe, a motor fixed to the upper part of the fertilizer discharge pipe, a conveying screw fixed to the output shaft of the motor, the conveying screw being located inside the fertilizer discharge pipe, a conveying pipe connected to the upper part of the fertilizer discharge pipe, and an air blowing pipe connected to the lower part of the fertilizer discharge pipe.

[0006] The lower end of the fertilizer discharge pipe is fixed with a connecting sleeve, and a trenching shovel is fixed on the connecting sleeve.

[0007] The upper part of the fertilizer discharge pipe is fixed with a connecting frame, which is fixed on a crossbeam. Multiple fertilizer discharge pipes can be installed on the crossbeam.

[0008] A connecting seat is fixed on the crossbeam, and two vertical rods are vertically slidably connected to the connecting seat. A soil covering component is fixed between the lower ends of the two vertical rods. A telescopic rod is fixed on the connecting seat, and the movable end of the telescopic rod is fixed to the soil covering component.

[0009] A support plate is fixed to the upper side of the crossbeam, a collar is fixed to the upper part of the support plate, a fertilizer box is fixed to the collar, a connector is provided at the lower end of the fertilizer box, the upper end of the plastic hose is connected to the connector, and the lower end of the plastic hose is connected to the upper part of the conveying pipe.

[0010] A slot is provided on the left side of the connector, and a gate is slidably connected to the support plate. The gate can be inserted into the slot and extend into the connector to control the size of the connector opening. A telescopic rod three is fixed on the support plate, and the movable end of the telescopic rod three is fixed on the gate.

[0011] A side frame is fixed to the collar, and a fan is fixed to the side frame. The air outlet of the fan is connected to the upper part of the air blowing pipe.

[0012] Both ends of the upper side of the crossbeam are fixed with lifting rods. The two lifting rods are vertically slidably connected to the fixed frame. The fixed frame is fixed with two telescopic rods. The movable ends of the two telescopic rods are respectively fixed to the upper ends of the two lifting rods. The fixed frame is fixed with two screw sockets, and each screw socket is provided with a screw hole.

[0013] The fertilizer box is fixed to a bracket at its upper part. A round rod is vertically slidably connected to the bracket. The round rod is coaxial with the fertilizer box and the connector. Multiple protrusions are evenly distributed on the round rod. A stop pin is fixed on the round rod and blocks the lower side of the bracket. A round plate is fixed to the upper part of the round rod. A compression spring is sleeved on the upper part of the round rod. The compression spring is located between the round plate and the bracket. A telescopic rod four is fixed to the bracket. A toggle plate is fixed to the movable end of the telescopic rod four and presses against the upper side of the round plate.

[0014] A portal frame is fixed to one side of the fertilizer box. A horizontal rod is slidably connected to the portal frame. A hammer is fixed to the left end of the horizontal rod. A compression spring is sleeved on the horizontal rod and is located between the hammer and the portal frame.

[0036] A force-push type rice side-deep fertilization device includes a fertilizer discharge pipe 101. A motor 104 is fixed to the upper part of the fertilizer discharge pipe 101. A conveying screw 109 is fixed to the output shaft of the motor 104. The conveying screw 109 is located inside the fertilizer discharge pipe 101. A conveying pipe 102 is connected to the upper part of the fertilizer discharge pipe 101, and an air blowing pipe 108 is connected to the lower part of the fertilizer discharge pipe 101.

[0037] like Figure 5-6 As shown;

[0038] After the motor 104 starts, it drives the conveying screw 109 on the output shaft to rotate at high speed in the fertilizer discharge pipe 101. After the fertilizer enters the upper part of the fertilizer discharge pipe 101 through the conveying pipe 102, it moves to the lower part of the fertilizer discharge pipe 101 under the spiral pushing action of the conveying screw 109. At the same time, the air blowing pipe 108 connects to the airflow and blows air to the lower part of the fertilizer discharge pipe 101. The airflow and the fertilizer pushed by the screw form a synergistic effect, which pushes the fertilizer to the outlet of the fertilizer discharge pipe 101, realizing the efficient delivery of fertilizer, delivering the fertilizer to a deeper position, and the air blowing makes the fertilizer more dispersed in the soil, which is more convenient for the fertilizer to be absorbed.

[0039] The lower end of the fertilizer discharge pipe 101 is fixed with a connecting sleeve 107, and a trenching shovel 106 is fixed on the connecting sleeve 107.

[0040] like Figure 5-6 As shown;

[0041] During the movement of the device, the lower end of the fertilizer discharge pipe 101 is directly in contact with the field soil via the ditching shovel 106 fixed by the connecting sleeve 107. As the device moves forward, the ditching shovel 106 cuts into the soil, forming a trench that meets the requirements of side-deep fertilization. The fertilizer delivered by the fertilizer discharge pipe 101 can be directly discharged into the trench, laying the foundation for the precise burial of fertilizer in the soil and ensuring that the fertilization depth meets the growth needs of rice.

[0042] A connecting frame 105 is fixed to the upper part of the fertilizer discharge pipe 101. The connecting frame 105 is fixed to the crossbeam 201, and multiple fertilizer discharge pipes 101 can be installed on the crossbeam 201.

[0043] like Figure 5-8 As shown;

[0044] The fertilizer discharge pipe 101 is securely connected to the crossbeam 201 via the connecting frame 105, providing reliable support and positioning for the fertilizer discharge pipe 101. The crossbeam 201 provides a uniform installation benchmark for the fertilizer discharge pipe 101, ensuring the installation angle and positional accuracy of components such as the fertilizer discharge pipe 101 and the furrowing shovel 106. Simultaneously, it facilitates the synchronous movement of the entire fertilizer discharge pipe 101 via the crossbeam 201, ensuring uniformity and consistency of fertilization in the field. With multiple fertilizer discharge pipes arranged on the crossbeam 201, the device can complete the fertilization of multiple rows of rice in a single movement, significantly reducing the number of field operations and travel distances. This is particularly suitable for large-scale planting needs in large-area rice fields, reducing labor and time costs.

[0045] A connecting seat 204 is fixed on the crossbeam 201. Two vertical rods 202 are vertically slidably connected to the connecting seat 204. A soil covering component 205 is fixed between the lower ends of the two vertical rods 202. A telescopic rod 203 is fixed on the connecting seat 204. The movable end of the telescopic rod 203 is fixed on the soil covering component 205.

[0046] like Figure 7-8 As shown;

[0047] After the trenching shovel 106 digs the trench and completes fertilization, the telescopic rod 203 can adjust the extension amount according to the soil conditions and fertilization depth. The movable end drives the covering part 205 to slide vertically along the vertical rod 202 on the connecting seat 204, adjusting the contact height between the covering part 205 and the ground. When the covering part 205 moves forward with the device, it pushes the soil on both sides of the trench back into the trench, realizing the covering operation after fertilization and avoiding fertilizer exposure and volatilization.

[0048] A support plate 405 is fixed to the upper side of the crossbeam 201. A collar 404 is fixed to the upper part of the support plate 405. A fertilizer box 401 is fixed to the collar 404. A connector 409 is provided at the lower end of the fertilizer box 401. The upper end of the plastic hose 103 is connected to the connector 409. The lower end of the plastic hose 103 is connected to the upper part of the conveying pipe 102.

[0049] like Figure 5-6 As shown in Figures 10-11;

[0050] The fertilizer box 401 is fixed to the crossbeam 201 by the collar 404 and the support plate 405, so as to correspond with the position of the fertilizer discharge pipe 101. The fertilizer in the fertilizer box 401 flows out through the connector 409 at the lower end under the action of gravity, and is transported to the delivery pipe 102 of the fertilizer discharge pipe 101 through the plastic hose 103. The plastic hose 103 has a certain degree of flexibility and can adapt to slight displacement and angle changes during the operation of the device, ensuring the smooth flow of fertilizer and providing a continuous fertilizer supply for the subsequent strong push fertilization of the fertilizer discharge pipe 101.

[0051] A slot 408 is provided on the left side of the connector 409. A gate 407 is slidably connected to the support plate 405. The gate 407 can be inserted into the slot 408 and extend into the connector 409 to control the opening size of the connector 409. A telescopic rod 406 is fixed on the support plate 405. The movable end of the telescopic rod 406 is fixed on the gate 407.

[0052] like Figure 10-11 As shown;

[0053] The telescopic rod 406 drives the gate 407 to slide along the support plate 405 through its telescopic movement. After the gate 407 is inserted into the slot 408 on the left side of the connector 409, it can extend into the inside of the connector 409. By adjusting the depth of the gate 407 into the connector 409, the opening size of the connector 409 is changed, thereby adjusting the flow rate of fertilizer from the fertilizer box 401 and realizing the control of the fertilizer discharge of the fertilizer box 401.

[0054] A side frame 402 is fixed on the collar 404, and a fan 403 is fixed on the side frame 402. The air outlet of the fan 403 is connected to the upper part of the air blowing pipe 108.

[0055] like Figure 5-6 As shown in Figures 10-11;

[0056] The side frame 402 provides stable installation support for the blower 403. After the blower 403 is started, it generates high-pressure airflow. The airflow is delivered to the air blowing pipe 108 through the air blowing port. The air blowing pipe 108 guides the airflow to the lower part of the fertilizer discharge pipe 101, where it meets the fertilizer pushed by the conveying screw 109. On the one hand, the airflow provides downward thrust to the fertilizer, enhancing the conveying power of the fertilizer. On the other hand, it can blow away any fertilizer that may clump in the fertilizer discharge pipe 101, ensuring that the fertilizer is discharged evenly and smoothly into the trench, thus improving the fertilization effect.

[0057] Both ends of the upper side of the crossbeam 201 are fixed with lifting rods 304. The two lifting rods 304 are vertically slidably connected to the fixed frame 301. The fixed frame 301 is fixed with two telescopic rods 303. The movable ends of the two telescopic rods 303 are respectively fixed to the upper ends of the two lifting rods 304. The fixed frame 301 is fixed with two screw sockets 302. Each screw socket 302 is provided with a screw hole.

[0058] like Figure 7-9 As shown;

[0059] The device can be fixed to a mobile carrier such as agricultural machinery by means of the screw socket 302 and screw holes on the fixed frame, so that the device can be moved and operated. When the telescopic rod 2 303 extends and retracts synchronously, it drives the lifting rods 304 on both sides of the crossbeam 201 to slide vertically along the fixed frame 301, thereby adjusting the overall height of the crossbeam 201 and the fertilizer pipe 101 and the ditching shovel 106 below, so as to adapt to different field terrain, soil thickness or fertilizer depth requirements, and ensure the accuracy of ditching and fertilization positions.

[0060] A bracket 501 is fixed to the upper part of the fertilizer box 401. A round rod 510 is vertically slidably connected to the bracket 501. The round rod 510 is coaxially arranged with the fertilizer box 401 and the connector 409. Multiple protrusions 509 are evenly distributed on the round rod 510. A stop pin 511 is fixed on the round rod 510 and blocks the lower side of the bracket 501. A round plate 504 is fixed to the upper part of the round rod 510. A compression spring is sleeved on the upper part of the round rod 510. The compression spring is located between the round plate 504 and the bracket 501. A telescopic rod 502 is fixed to the bracket 501. A toggle plate 503 is fixed to the movable end of the telescopic rod 502 and presses against the upper side of the round plate 504.

[0061] like Figure 10-13 As shown;

[0062] When the telescopic rod 502 extends and retracts cyclically, it drives the actuating plate 503 to move up and down. The actuating plate 503 presses down on the circular plate 504, causing the circular rod 510 to slide down along the bracket 501, while the compression spring is compressed. When the telescopic rod 502 extends, the actuating plate 503 moves upward, and the compression spring returns to its original position, generating an upward elastic force that pushes the circular plate 504 and the circular rod 510 to return to their original position. The stop pin 511 can limit the upward sliding stroke of the circular rod 510. When the circular rod 510 moves up and down reciprocally, the protrusions 509 on its surface agitate the fertilizer in the fertilizer box 401 to prevent the fertilizer from clumping and ensure that the fertilizer can flow out smoothly through the connector 409, thus ensuring the continuity of fertilization.

[0063] A portal frame 507 is fixed to one side of the fertilizer box 401. A horizontal rod 506 is slidably connected to the portal frame 507. A hammer head 508 is fixed to the left end of the horizontal rod 506. A compression spring is sleeved on the horizontal rod 506. The compression spring is located between the hammer head 508 and the portal frame 507. One end of the inclined rod 505 is hinged to the circular plate 504, and the other end of the inclined rod 505 is hinged to the horizontal rod 506.

[0064] like Figure 10-13 As shown;

[0065] When the circular plate 504 moves up and down with the circular rod 510, the horizontal rod 506 is driven to slide laterally along the portal frame 507 through the hinged diagonal rod 505. When the circular plate 504 moves downward, the diagonal rod 505 pushes the horizontal rod 506 to slide away from the fertilizer box 401, and the hammer head 508 moves away from the side wall of the fertilizer box 401 and compresses the compression spring on the horizontal rod 506. When the circular plate 504 returns to its original position, the compression spring releases its elastic force, pushes the horizontal rod 506 to slide closer to the fertilizer box 401, and the hammer head 508 hits the side wall of the fertilizer box 401, generating a vibration effect, shaking off the fertilizer attached to the inner wall of the fertilizer box 401, avoiding fertilizer residue and waste, and further preventing fertilizer caking, thus ensuring the fertilizer discharge efficiency of the fertilizer box 401.
