Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a device for spreading and covering fertilizer with soil in high-standard farmland. Background Technology

[0002] A fertilizer spreading and covering device is a type of machinery used in agricultural production. It is primarily used to evenly spread fertilizer on the surface of farmland soil and then cover it with soil to improve fertilizer utilization and reduce volatilization or loss. This device is widely used in high-standard farmland, orchards, and vegetable cultivation, significantly improving fertilization efficiency, reducing labor intensity, and promoting nutrient absorption by crops, thus meeting the needs of precision agriculture.

[0003] The existing Chinese patent with publication number CN219741224U discloses a device for spreading and covering fertilizer with soil. The existing technical solution mentioned above has the following defects. Although the above technical solution achieves a continuous and efficient fertilizer spreading process by setting an intermittent spreading component in conjunction with high-standard seedling pits in farmland, and further reduces the possibility of fertilizer adhering to the inner wall of the device by setting a tapping component, the soil covering plate in the above technical solution adopts a fixed design and lacks height adjustment function. This makes it impossible to make adaptive adjustments according to different operating scenarios (such as different crop planting depth requirements or differences in soil conditions), which seriously restricts the applicability and operational flexibility of the device and reduces its practicality and adaptability in complex agricultural environments.

[0004] Therefore, based on this, the technical solution of this utility model is proposed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a device for spreading and covering fertilizer in high-standard farmland, comprising a housing, a fixing plate fixedly installed inside the housing, and feeding ports extending through both sides of the top surface of the fixing plate. An electric push rod is fixedly installed at the center of the bottom surface of the fixing plate, and the output end of the electric push rod is fixedly connected to a mounting shell. A second motor is fixedly installed on the upper surface of the bottom end of the mounting shell. A feeding pipe is fixedly installed at the center of the bottom surface of the housing, and the output end of the second motor is fixedly connected to a spreading disc through the feeding pipe. A connecting frame is fixedly connected to one side surface, and a horizontal plate is fixedly connected inside the connecting frame. A first motor is fixedly installed at the middle position of the top surface of the horizontal plate, and a screw is fixedly connected to the output end of the first motor. A threaded cylinder is threadedly connected to the screw, and a fixed frame is fixedly connected to one end of the threaded cylinder. A connecting plate is provided inside the fixed frame. A soil covering roller is fixedly installed at the middle position of the bottom surface of the connecting plate through the opening on the bottom surface of the connecting frame. Limiting blocks are provided on both sides of the threaded cylinder, and one end of the limiting block extends into the limiting groove opened on both sides of the inner wall of the connecting frame.

[0006] A spring is fixedly installed between the connecting plate and the fixed frame. A connecting block is provided at the middle position of both sides of the connecting plate, and one end of the connecting block extends into the interior of the connecting groove opened on both sides of the inner wall of the fixed frame. The connecting block and the connecting groove are rectangular structures, and the connecting block and the connecting groove are slidably connected.

[0007] A guide plate is provided at the middle position of the top surface of the fixed plate, and the guide plate is fixedly connected to the fixed plate.

[0008] Rollers are fixedly installed on both sides of the bottom surface of the box body, located on the bottom surface of the feeding pipe.

[0009] The bottom upper surface of the box is provided with baffles on both sides, the baffles are fixedly connected to the box, and the baffles are matched with the box.

[0010] The front surface of the box is provided with a movable plate, and the movable plate is fixedly connected to the box by screws.

[0011] A handle is provided on one side surface of the connecting frame, and the handle is fixedly connected to the box body.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention involves adding fertilizer into the housing, activating an electric push rod to move the mounting shell and the second motor, causing the spreading disc at the output end of the second motor to move out of the feeding pipe, at which point the feeding pipe is open. Subsequently, the second motor drives the spreading disc to rotate, achieving uniform spreading of fertilizer. Simultaneously, the covering roller at the bottom of the connecting plate completes the covering operation. To address the issue of adjusting the covering height, the device activates the first motor on the horizontal plate to drive the screw to rotate. Under the synergistic action of the limiting block and the limiting groove, the threaded cylinder moves along the screw axis and drives the entire fixed frame to rise and fall, thereby precisely adjusting the working height of the covering roller. This adjustment mechanism effectively solves the limitations of traditional fixed covering plates, enabling the device to flexibly adjust operating parameters according to different crop planting depths or soil conditions, thus improving the adaptability and practical value of the equipment.

[0014] This invention uses the synergistic action of a fixed frame, spring, and connecting plate to apply elastic limiting to the covering roller, ensuring that the covering roller maintains stable contact with the ground during operation. The elastic compensation function of the spring can adapt to changes in ground undulations, ensuring that the covering roller can maintain optimal contact under different terrain conditions, thereby significantly improving the uniformity and density of fertilizer coverage. This elastic buffer mechanism effectively avoids the uneven or missed covering phenomenon caused by uneven ground in traditional rigid structures, further optimizing the covering effect and operational reliability of the device.

[0026] Please refer to Figure 1-4A device for spreading and covering fertilizer in high-standard farmland includes a housing 1. A fixing plate 15 is fixedly installed inside the housing 1. A discharge port 14 extends through both sides of the top surface of the fixing plate 15. An electric push rod 16 is fixedly installed at the center of the bottom surface of the fixing plate 15, and the output end of the electric push rod 16 is fixedly connected to a mounting shell 17. A second motor 18 is fixedly installed on the upper surface of the bottom end of the mounting shell 17. A discharge pipe 12 is fixedly installed at the center of the bottom surface of the housing 1. The output end of the second motor 18 extends through the discharge pipe 12 and is fixedly connected to a spreading disc 11. A connecting frame 3 is fixedly connected to one side surface of the housing 1, and a horizontal plate 5 is fixedly connected inside the connecting frame 3. A first motor 4 is fixedly installed at the center of the top surface of the horizontal plate 5, and a screw 25 is fixedly connected to the output end of the first motor 4. A threaded cylinder 26 is threaded onto the screw 25. A fixing frame 20 is fixedly connected to one end of the threaded cylinder 26, and a connecting plate 22 is provided inside the fixing frame 20. A connecting plate 22 is located at the center of the bottom surface of the connecting plate 22. A soil covering roller 9 is fixedly installed through the opening 8 on the bottom surface of the connecting frame 3. Limiting blocks 6 are provided on both sides of the threaded cylinder 26, and one end of the limiting block 6 extends into the limiting groove 7 opened on both sides of the inner wall of the connecting frame 3. When fertilizer is added to the box 1, the electric push rod 16 is activated to push the mounting shell 17 and the second motor 18 to move, so that the spreading disc 11 at the output end of the second motor 18 moves out of the feeding pipe 12. At this time, the feeding pipe 12 is in an open state. Then the second motor 18 drives the spreading disc 11 to rotate to achieve uniform spreading of fertilizer. At the same time, the soil covering roller 9 at the bottom of the connecting plate 22 completes the soil covering operation. By activating the first motor 4 on the horizontal plate 5 to drive the screw 25 to rotate, under the synergistic action of the limiting block 6 and the limiting groove 7, the threaded cylinder 26 moves along the axial direction of the screw 25 and drives the fixed frame 20 to rise and fall as a whole, thereby precisely adjusting the working height of the soil covering roller 9. This allows the device to flexibly adjust the operating parameters according to different crop planting depths or soil conditions, improving the adaptability and practical value of the equipment.

[0027] In one embodiment, a spring 21 is fixedly installed between the connecting plate 22 and the fixed frame 20. A connecting block 24 is provided at the middle position of both sides of the connecting plate 22, and one end of the connecting block 24 extends into the interior of the connecting groove 23 opened on both sides of the inner wall of the fixed frame 20. The connecting block 24 and the connecting groove 23 are rectangular structures, and the connecting block 24 is slidably connected to the connecting groove 23. Through the synergistic action of the fixed frame 20, the spring 21 and the connecting plate 22, an elastic limit is applied to the covering roller 9, so that the covering roller 9 always maintains stable contact with the ground during operation. The elastic compensation function of the spring 21 can adapt to the changes in ground undulation, ensuring that the covering roller 9 can maintain the best contact state under different terrain conditions, thereby significantly improving the uniformity and density of fertilizer coverage. This elastic buffer mechanism effectively avoids the uneven or missed covering phenomenon caused by uneven ground in traditional rigid structures, further optimizing the covering effect and operational reliability of the device.

[0028] In one embodiment, a guide plate 13 is provided at the middle position of the top surface of the fixing plate 15. The guide plate 13 is fixedly connected to the fixing plate 15. The use of the guide plate 13 can guide the fertilizer on the top of the fixing plate 15 to prevent it from remaining on the top of the fixing plate 15, thereby facilitating the delivery of the fertilizer to the bottom of the box 1.

[0029] In one embodiment, rollers 10 are fixedly installed on both sides of the bottom surface of the housing 1 on the feed pipe 12, and the housing 1 can be moved by using the rollers 10.

[0030] In one embodiment, baffles 19 are provided on both sides of the bottom upper surface of the box 1. The baffles 19 are fixedly connected to the box 1 and match the box 1. The use of the baffles 19 can guide the fertilizer at the bottom of the box 1 to prevent it from remaining at the bottom of the box 1, thereby facilitating the discharge and spreading of fertilizer.

[0031] In one embodiment, a movable plate is provided on the front surface of the housing 1, and the movable plate is fixedly connected to the housing 1 by screws. By loosening the screws and removing the movable plate, the components in the housing 1 can be maintained and repaired.

[0032] In one embodiment, a handle 2 is provided on one side surface of the connecting frame 3. The handle 2 is fixedly connected to the box body 1, and the use of the handle 2 facilitates the movement of the box body 1.

[0033] In one embodiment, the control switch control circuit can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0034] Working principle:

[0035] In use, fertilizer is first added to the housing 1. The electric push rod 16 is then activated to move the mounting shell 17 and the second motor 18, causing the spreading disc 11 at the output end of the second motor 18 to move out of the discharge pipe 12. At this point, the discharge pipe 12 is open. The second motor 18 then drives the spreading disc 11 to rotate, achieving uniform fertilizer spreading. Simultaneously, the covering roller 9 at the bottom of the connecting plate 22 completes the covering operation. This is achieved by activating the first motor 4 on the horizontal plate 5 to drive the screw 25 to rotate. Under the coordinated action of the limiting block 6 and the limiting groove 7, the threaded cylinder 26 moves axially along the screw 25, causing the fixed frame 20 to rise and fall as a whole, thereby precisely adjusting the working height of the covering roller 9. This allows the device to adjust according to the operating height of the covering roller 9. The flexible adjustment of operating parameters based on different crop planting depths or soil conditions enhances the adaptability and practical value of the equipment. The coordinated action of the fixed frame 20, spring 21, and connecting plate 22 applies elastic limiting to the covering roller 9, ensuring that the covering roller 9 maintains stable contact with the ground during operation. The elastic compensation function of the spring 21 can adapt to changes in ground undulations, ensuring that the covering roller 9 maintains optimal contact under different terrain conditions, thereby significantly improving the uniformity and density of fertilizer coverage. This elastic buffer mechanism effectively avoids the uneven or missed covering phenomenon caused by uneven ground in traditional rigid structures, further optimizing the covering effect and operational reliability of the device.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
