Description

Technical Field

[0001] This utility model relates to the field of fertilizer distribution technology, specifically a fertilizer dispenser for precision fertilization. Background Technology

[0002] In agricultural planting, fertilization is a crucial step in ensuring crop yield and quality. Traditional fertilization methods mainly rely on manual spreading or the use of simple spreading equipment. These methods suffer from problems such as uneven fertilizer distribution, inaccurate dosage control, and serious volatilization and loss, resulting not only in huge economic waste and environmental pollution, but also failing to meet the technical requirements of modern agriculture for "precision agriculture".

[0003] An existing patent (authorization announcement number: CN223207527U) discloses an auxiliary structure for a rice fertilization device. The key technical point of the solution is that by setting up a motor and a stirring rod, the motor drives the stirring rod to rotate at high speed in the mixing chamber, which strongly stirs the water and fertilizer. This stirring action can make the fertilizer fully dissolve in the water, ensuring that the fertilizer and water are evenly mixed. For different types of fertilizers, the rotation of the stirring rod can break up the clumps between fertilizer particles, dispersing them and forming a finer mixture. In this way, during the fertilization process, the fertilizer can be applied more evenly to the rice field, avoiding the situation of too much or too little fertilizer in some areas, and improving the fertilization effect and uniformity.

[0004] However, the above-mentioned technical solutions still have certain defects. Although such equipment is highly efficient, it has obvious drawbacks: First, its structure is complex and its cost is high, making it unsuitable for small and medium-sized farmers or small plots of land in hilly areas; second, its fertilization mechanism mostly uses independent power drive, and the amount of fertilizer applied is not synchronized with the machine's speed, resulting in uneven fertilization when the machine starts or stops or changes speed, making it difficult to achieve truly precise control. Therefore, a fertilizer dispenser for precision fertilization is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a fertilizer dispenser for precision fertilization to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A fertilizer dispenser for precision fertilization includes a frame, an auxiliary wheel on the front part of the frame, a transmission component inside the frame to move the frame, a soil loosening component at the bottom of the frame to till the soil, and a fertilizer distribution component on the side of the soil loosening component at the bottom of the frame to dynamically dispense fertilizer. The transmission assembly includes a drive motor fixedly mounted at the bottom of the frame, a fixed housing mounted on the side of the drive motor, a shaft connected to the output end of the drive motor, a pulley passing through the shaft, and a drive wheel driven by the pulley via a belt. The distribution assembly includes a transmission rod fixedly installed at the center of the drive wheel, a discharge roller fixedly connected to the transmission rod, a material conveying channel extending through the discharge roller, a material collection bucket at the top of the material conveying channel, a discharge cavity at the bottom of the material conveying channel, and a limit element threadedly provided at the end of the transmission rod away from the discharge roller.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: As a further embodiment of this utility model: the transmission assembly also includes a traveling wheel disposed at the end away from the drive motor, and the shaft is rotatably disposed within the fixed housing.

[0008] As a further improvement of this utility model, multiple sets of anti-slip blocks are provided on the circumferential surface of the walking wheel.

[0009] As a further improvement of this utility model, the anti-slip blocks are arranged in an inclined manner.

[0010] As a further embodiment of this utility model: the loosening component includes a frame fixed to the bottom of the vehicle frame, a bracket connected to the frame via a hinge shaft, multiple sets of elastic reset components between the bracket and the frame, and multiple ground-turning claws installed at the bottom of the bracket.

[0011] As a further improvement of this utility model, the discharge roller is a cylindrical structure with multiple sets of circular grooves on its surface.

[0012] As a further improvement of this utility model: the material conveying channel is made of flexible wear-resistant material, and its inner wall is elastically fitted with the material holding structure of the discharge roller.

[0013] As a further improvement of this utility model, the discharge roller is detachable and is equipped with multiple replaceable discharge rollers with different volume specifications for material holding structures.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the linkage between the transmission component and the distribution component, not only eliminates the need for an additional power source for the fertilizer distribution component, but also ensures that the amount of fertilizer applied is only linked to the travel distance. Regardless of the speed of the equipment, the amount of fertilizer obtained per unit area of ​​land remains constant, thus solving the problem of uneven fertilization caused by speed changes.

[0015] 2. This utility model, by incorporating a soil-loosening component, addresses the issue that traditional fixed soil-loosening claws, when encountering rocks, may be forced to stop, or even suffer bending, breakage, or damage to the frame or transmission system. This design, however, utilizes a lifting and resetting mechanism to allow obstacles to pass smoothly, thus improving the equipment's durability and reliability. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] In one embodiment, such as Figures 1-5 As shown, a fertilizer dispenser for precision fertilization includes a frame 1. The front part of the frame 1 is provided with auxiliary wheels 2. The frame 1 is also provided with a transmission component 3 that drives the frame 1 to move. The bottom of the frame 1 is also provided with a soil loosening component 4 for tilling the soil. The side of the soil loosening component 4 at the bottom of the frame 1 is also provided with a fertilizer distribution component 5 for dynamic fertilizer dispensing. In this embodiment, the transmission assembly 3 provides power to drive the frame 1 and its bottom wheels 34 forward. The front auxiliary wheel 2 is responsible for guidance and balance, ensuring stable movement of the equipment. While the equipment is moving, the loosening assembly 4 installed at the bottom of the frame 1 starts to work, breaking up and turning over the soil in front, and distributing fertilizer to the turned soil through the distribution assembly 5, ensuring that every inch of soil is evenly and accurately fertilized.

[0020] In one embodiment, such as Figure 4 As shown, the transmission assembly 3 includes a drive motor 31 fixedly installed at the bottom of the frame 1. A fixed housing 32 is installed on the side of the drive motor 31. A shaft is connected to the output end of the drive motor 31. A pulley 33 passes through the shaft. The pulley 33 drives a drive wheel 36 via a belt. A traveling wheel 34 is located at the end away from the drive motor 31. The shaft is rotatably mounted inside the fixed housing 32. Multiple sets of anti-slip blocks are arranged on the circumferential surface of the traveling wheel 34, and the anti-slip blocks are arranged at an angle. The drive motor 31 drives the pulley 33 to rotate through the drive shaft. The pulley 33 transmits power to the drive wheel 36 via the belt, providing power to the distribution assembly 5. At the same time, the shaft of the main body drives the traveling wheel 34 to rotate. During the movement of the equipment, the anti-slip blocks arranged at an angle on the circumferential surface of the traveling wheel 34 will continuously insert into and detach from the soil, providing continuous grip.

[0021] In one embodiment, such as Figure 3 As shown, the loosening assembly 4 includes a frame 41 fixed to the bottom of the chassis 1. A bracket 42 is connected to the frame 41 via a hinge shaft. Multiple sets of elastic reset members 43 are provided between the bracket 42 and the frame 41. Multiple turning claws 44 are installed at the bottom of the bracket 42. Under the weight of the equipment and the forward thrust, the turning claws 44 insert into the soil. As the equipment moves forward, the soil is broken and tilled to prepare for subsequent fertilization and ditching. At this time, the bracket 42, the turning claws 44 and the frame 41 can be regarded as a whole. They can rotate simply via the hinge shaft, but the elastic reset members 43 are compressed, providing a downward pressure to ensure that the turning claws 44 can stably cut into the soil. When the turning claws 44 encounter hard obstacles during the forward movement, a huge reverse impact force is generated. This impact force will force the turning claws 44 and the bracket 42 connected to them to lift upward around the hinge shaft. The upward lifting action of the bracket 42 will further compress or stretch the elastic reset members 43. During this process, the impact energy is absorbed by the elastic component, preventing the rigid impact from being directly transmitted to the entire frame 1.

[0022] In one embodiment, such as Figure 5As shown, the distribution assembly 5 includes a transmission rod 55 fixedly installed at the center of the drive wheel 36. The transmission rod 55 is fixedly connected to a discharge roller 53, which passes through a material conveying channel 52. A collection bucket 51 is provided at the top of the material conveying channel 52, and a discharge chamber 54 is provided at the bottom of the material conveying channel 52. A limiting element 56 is threaded onto the end of the transmission rod 55 away from the discharge roller 53. The discharge roller 53 is a cylindrical structure with multiple sets of circular grooves on its surface. The material conveying channel 52 is made of flexible wear-resistant material, and its inner wall elastically fits the material-containing structure of the discharge roller 53. The discharge roller 53 is detachable and is equipped with multiple replacement discharge rollers 53 with different material-containing structures and volume specifications. One end of the moving rod 55 is directly fixed to the center of the drive wheel 36. For every rotation of the traveling wheel 34, the driving rod 55 is forced to rotate one revolution. When the discharge roller 53 rotates with the driving rod 55, the circular grooves on its surface will pass through the outlet of the upper collection bucket 51 in sequence. Each circular groove scoops up a fixed volume of fertilizer as it passes through. When the circular groove rotates to the position of the lower discharge chamber 54, due to the loss of pressure from the fertilizer above and the opening facing downwards, the fertilizer contained inside will automatically fall under the action of gravity and be evenly applied to the soil that has been tilled by the loosening component 4 through the discharge chamber 54. The faster the traveling wheel 34 rotates, the faster the fertilizer is distributed. The fertilizer distribution speed can be automatically adjusted through a simple structure.

[0023] The above embodiment discloses a fertilizer dispenser for precision fertilization, wherein the power of the drive motor 31 is transmitted to the drive wheel 36 through a belt transmission system. The inclined anti-slip blocks on the drive wheel 36 firmly grip the ground, driving the entire frame 1 to move forward stably. The auxiliary wheel 2 at the front is responsible for guidance and balance. As the device moves forward, the ground loosening component 4 at the bottom of the frame 1 starts to work, and the soil turning claw 44 breaks the soil under the push of the device, creating neat trenches for fertilization. If it suddenly encounters obstacles such as rocks, the turning claw 44 will instantly lift over them under the action of the hinge shaft and the elastic reset component 43, and then quickly reset to protect itself from damage and maintain the continuity of operation. The rotation of the drive wheel 36 directly drives the discharge roller 53 to rotate synchronously through the transmission rod 55 fixed on its shaft. When the evenly distributed circular grooves on the surface of the discharge roller 53 rotate to the top, they scoop up a fixed volume of fertilizer from the conveying channel 52 below the collection bucket 51. When the circular grooves rotate to the bottom and are aligned with the discharge cavity 54, the fertilizer falls into the soft trench just dug by the turning claw 44 under the action of gravity. A fixed volume of fertilizer is released every time the rollers advance a fixed distance.

[0024] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
