Description

Technical Field

[0001] This utility model belongs to the field of rice planting technology, and in particular to a rice fertilization device. Background Technology

[0002] Rice is a herbaceous plant belonging to the genus Oryza, and is the most important and oldest food crop in the Oryza genus. Rice cultivation is particularly important in grain production, and rice fertilization is one of the necessary steps to increase rice yield. People often use fertilization devices to fertilize rice. However, most fertilization devices now have fixed spray heads, which are not easy to adjust, resulting in a small spraying range. This requires repeated spraying and covering, which easily leads to waste of fertilizer resources.

[0003] A Chinese patent (authorization announcement number CN211909654U) discloses a fertilizer application device for rice seedling beds, which includes: "a fertilizer box, a support platform, a moving rod, a sleeve rod, and a rotating rod. The fertilizer box is fixedly installed on a trolley. A fixed frame is fixedly connected to the center of the top of the fertilizer box. A drive motor is fixedly installed inside the fixed frame. The output shaft of the drive motor passes through the fertilizer box and extends into the fertilizer box, where it is fixedly connected to a stirring shaft."

[0004] It is evident that the cited patent document suffers from the problem of inconvenience in adjusting the spraying range. Utility Model Content

[0005] The purpose of this invention is to provide a rice fertilization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rice fertilization device, comprising a fertilization base, a fixed box mounted on the top surface of the fertilization base, a horizontal plate above the fixed box, two racks welded to the top surface of the horizontal plate, two vertical plates symmetrically welded to the top surface of the fixed box, a rotating shaft rotatably connected to the inner sidewalls of the two vertical plates via pins, gears meshing with racks fixedly sleeved on the periphery of the two rotating shafts, adjusting plates fixedly sleeved on the periphery of the two rotating shafts, mounting plates welded to the top surface of the two adjusting plates, a nozzle for spraying fertilizer onto the rice on one side of each of the two mounting plates, and a drive assembly for moving the horizontal plate through one side of the fixed box.

[0007] Preferably, the drive assembly includes a drive motor, transmission gears, a base block, and teeth, with the drive motor mounted on one side of the fixed housing.

[0008] Preferably, the output end of the drive motor extends into the inner cavity of the fixed box, and the transmission gear is connected to the output end of the drive motor.

[0009] Preferably, the bottom block is welded to the bottom surface of the horizontal plate, and the teeth are installed on one side of the bottom block, and the teeth mesh with the transmission teeth.

[0010] Preferably, the inner walls on both sides of the fixed box are provided with limiting blocks for restricting the movement of the horizontal plate and the bottom block, and the two sides of the horizontal plate and the bottom block are provided with limiting grooves that are adapted to slide with the limiting blocks.

[0011] Preferably, the top surface of the fertilizer base is equipped with a storage cylinder for storing fertilizer resources, and the periphery of the storage cylinder is provided with a feeding pipe for conveying fertilizer resources.

[0012] Preferably, the free end of the feeding pipe is connected to two conveying pipes via a distributor, and the free ends of the two conveying pipes respectively pass through two mounting plates and are connected to two nozzles.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are:

[0014] This rice fertilization device, by moving a horizontal plate, provides power for the movement of two racks, which in turn cause the gears to rotate in a circular motion. This allows the nozzle to also rotate in a circular motion, thereby adjusting the nozzle angle and expanding the spraying range. Compared to existing devices that spray fertilizer onto rice, this device can adjust the nozzle angle to expand the spraying range and reduce waste caused by repeated spraying.

[0015] The drive components provide power for the longitudinal reciprocating motion of the horizontal plate, allowing the nozzles to adjust their angle. The welded limit blocks and the opening limit grooves limit the longitudinal reciprocating motion of the horizontal plate, preventing deviation. The installed storage cylinder stores fertilizer resources and delivers them to the nozzles for spraying through the feeding pipe and conveying pipe. Attached Figure Description

[0023] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0026] like Figures 1 to 4 The rice fertilization device shown includes a fertilization base 1, with four casters mounted on the bottom surface of the fertilization base 1 and a push handle mounted on the top surface of the fertilization base 1, allowing personnel to move the device to the work area using the push handle.

[0027] A fixed box 2 is installed on the top surface of the fertilizer base 1. A horizontal plate 3 is provided above the fixed box 2. Two racks 4 are welded to the top surface of the horizontal plate 3. Two vertical plates 5 are symmetrically welded to the top surface of the fixed box 2. The inner side walls of the two vertical plates 5 are rotatably connected to the rotating shafts 6 by pins. Gears 7 that mesh with the racks 4 are fixedly sleeved on the periphery of the two rotating shafts 6. By moving the horizontal plate 3, the horizontal plate 3 can drive the two racks 4 to move. Since the two racks 4 mesh with the two gears 7 respectively, the two moving racks 4 will drive the two gears 7 to rotate respectively. Since the rotating shafts 6 are rotatably connected to the inner side walls of the vertical plates 5 by pins, the rotating gears 7 drive the rotating shafts 6 to rotate.

[0028] Adjusting plates 8 are fixedly fitted around the periphery of both rotating shafts 6. Mounting plates 9 are welded to the top surface of both adjusting plates 8. Each mounting plate 9 has a nozzle 10 for spraying fertilizer onto the rice on one side. When the rotating shaft 6 rotates, it will drive the adjusting plates 8 to rotate, which in turn will drive the mounting plates 9 to rotate, thereby driving the nozzles 10 to rotate. This allows the angle of the nozzles 10 to be adjusted, thereby expanding the spraying range of fertilizer and reducing repeated spraying, thus reducing the waste of fertilizer.

[0029] The top surface of the fertilizer base 1 is equipped with a storage cylinder 17 for storing fertilizer resources. The storage cylinder 17 is provided with a feeding pipe 18 for conveying fertilizer resources. The storage cylinder 17 is also equipped with a pump for extracting fertilizer resources. A connecting pipe is connected between the pump and the storage cylinder 17. The feeding pipe 18 is connected to the pump. The free end of the feeding pipe 18 is connected to two conveying pipes 19 through a distributor. The free ends of the two conveying pipes 19 pass through two mounting plates 9 and are connected to two nozzles 10. A pad is installed on the periphery of the storage cylinder 17. The distributor is installed on the surface of the pad. By pumping, the fertilizer resources in the storage cylinder 17 can be conveyed to the feeding pipe 18 through the connecting pipe. At the same time, the fertilizer resources are distributed to the two conveying pipes 19 through the distributor. The fertilizer resources can then be conveyed to the nozzles 10 through the conveying pipes 19 and sprayed out, thus fertilizing the rice.

[0030] A drive assembly for moving the horizontal plate 3 is installed through one side of the fixed box 2. The drive assembly includes a drive motor 11, a transmission gear 12, a base block 13, and teeth 14. The drive motor 11 is mounted on one side of the fixed box 2 and can rotate in both directions. The output end of the drive motor 11 extends into the inner cavity of the fixed box 2. The transmission gear 12 is connected to the output end of the drive motor 11. The base block 13 is welded to the bottom surface of the horizontal plate 3. The teeth 14 are mounted on one side of the base block 13 and mesh with the transmission gear 12. By turning on the drive motor 11... The drive motor 11 can drive the transmission gear 12 to rotate. Since the transmission gear 12 meshes with the tooth 14, when the transmission gear 12 rotates, it will drive the base block 13 to move upward through the tooth 14, which in turn will drive the horizontal plate 3 to move upward. The angle of the nozzle 10 can be adjusted by the rack 4, gear 7, rotating shaft 6, adjusting plate 8 and mounting plate 9. When the drive motor 11 drives the transmission gear 12 to rotate in the opposite direction, it will drive the base block 13 to move downward through the tooth 14, which will drive the horizontal plate 3 to move downward. Thus, the angle of the nozzle 10 can be adjusted by the forward and reverse rotation of the drive motor 11.

[0031] The inner walls on both sides of the fixed box 2 are provided with limiting blocks 15 to restrict the movement of the horizontal plate 3 and the bottom block 13. The two sides of the horizontal plate 3 and the bottom block 13 are provided with limiting grooves 16 that are slidably adapted to the limiting blocks 15. When the horizontal plate 3 and the bottom block 13 move longitudinally back and forth, they will move around the limiting blocks 15 through the limiting grooves 16, which can limit the position of the horizontal plate 3 and the bottom block 13 and prevent deviation.

[0032] Working principle:

[0033] This rice fertilization device, when pushed by a person, sprays fertilizer onto the rice through the nozzle 10. During spraying, the drive motor 11 is turned on, driving the transmission gear 12 to continuously rotate forward and backward. Since the transmission gear 12 meshes with the tooth 14, the rotation of the transmission gear 12 will drive the base block 13 to move upward through the tooth 14, which in turn will drive the horizontal plate 3 and the rack 4 to move upward. Since the rack 4 meshes with the gear 7, the moving rack 4 will drive the gear 7 to rotate, which in turn will drive the rotating shaft 6 and the adjusting plate 8 to rotate. The rotation of the adjusting plate 8 will drive the nozzle 10 to rotate through the mounting plate 9. Combined with the continuous forward and reverse rotation of the transmission gear 12 driven by the drive motor 11, the nozzle 10 can be rotated back and forth, allowing the angle of the nozzle 10 to be adjusted, thereby expanding the spraying range of fertilizer resources, reducing repeated spraying, and reducing waste of fertilizer resources.
