Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a precision fertilization device for crops. Background Technology

[0002] Precision fertilization technology is a core technology for achieving agricultural modernization, improving fertilizer utilization, and reducing agricultural non-point source pollution. It is also an important research direction for the development of green and precision agriculture. In recent years, researchers at home and abroad have conducted extensive research on two core aspects: precise control of fertilizer application and precise location of fertilizer application. However, existing field fertilization equipment still has significant technical shortcomings and cannot meet the needs of large-scale, precision crop cultivation.

[0003] Existing fertilization equipment lacks directional precision. Traditional equipment often adopts a large-scale spreading fertilization mode, resulting in fertilizer being scattered and landing randomly. It is impossible to accurately deliver fertilizer to the roots of crops, and most of the fertilizer remains on the soil surface or in blank areas. This not only leads to extremely low fertilizer utilization and serious waste of resources, but also easily causes soil enrichment and pollution.

[0004] Meanwhile, the equipment's quantitative control is crude, and the traditional volumetric and gravity-type fertilizer discharge structures have poor stability. The amount of fertilizer discharged is easily affected by the physical properties of fertilizer such as fluidity, caking degree, and dryness / wetness. The amount of fertilizer discharged varies, making it impossible to achieve constant and precise quantitative fertilization. This can easily lead to problems such as fertilizer deficiency and fertilizer damage, seriously affecting the uniform growth of crops and restricting the widespread application of precision fertilization operations. Summary of the Invention

[0005] To address the technical problems in existing technologies, such as the inability to accurately deliver fertilizer to the roots of crops and the inconsistent output due to fertilizer clumping, thus failing to achieve constant and precise quantitative fertilization, this invention provides a targeted quantitative precision fertilization device for crops.

[0006] The present invention provides a precision fertilization device for crops, which adopts the following technical solution: A precision fertilization device for crops includes a frame, wheels, a storage bin, and a discharge pipe; the wheels are rotatably mounted on the bottom of the frame; the storage bin is located on the upper part of the frame, and the discharge pipe is located at the bottom of the storage bin and connected to the storage bin; an adaptive fertilization component is provided at the bottom end of the discharge pipe. A main shaft is rotatably mounted on the frame, and the main shaft is connected to the traveling wheels for transmission. A feeding wheel for quantitatively conveying fertilizer is installed inside the discharge pipe, and a discharge transmission mechanism for driving the feeding wheel to rotate is installed on the discharge pipe. The discharge transmission mechanism is connected to the main shaft, and the main shaft drives the feeding wheel to rotate through the discharge transmission mechanism. An adjustment component is installed on the discharge transmission mechanism.

[0007] This invention features a main shaft that synchronously drives the walking wheels and feeding wheels via a motor, ensuring synchronized movement and material feeding. It also includes a switchable adjustment mechanism that allows for independent movement without fertilization or simultaneous movement and fertilization. An adaptive fertilization component is located at the end of the discharge pipe, automatically conforming to the crop and delivering fertilizer to its roots. This invention precisely controls the amount of fertilizer applied around the crop, ensuring even and reasonable fertilizer application and improving crop growth quality.

[0008] A fixed platform is fixedly installed at the top of the frame, near the mounting base, and a mounting plate is fixedly installed at the end away from the mounting base; a motor that drives the walking wheels to rotate is fixedly installed on the fixed platform, and a storage box is fixedly installed on the mounting plate; the discharge pipe is fixedly installed at the bottom of the mounting plate; the motor is connected to the main shaft through a belt.

[0009] Provide an installation platform for the motor and storage bin; start the motor, which drives the main shaft to rotate via a belt.

[0010] The walking wheel is provided with a connecting shaft, and the walking wheel is rotatably connected to the mounting base through the connecting shaft; a driven transmission wheel is fixedly sleeved on the connecting shaft, and a driving transmission wheel that cooperates with the driven transmission wheel is fixedly sleeved on the main shaft; the driven transmission wheel and the driving transmission wheel are connected by a bottom chain.

[0011] The main shaft drives the traveling wheels to rotate via a bottom chain, enabling the equipment to move back and forth and complete the fertilization operation for crops.

[0012] The discharge transmission mechanism includes a drive shaft, a driven gear, and a driving gear; a drive shaft for driving the feeding wheel is rotatably arranged outside the discharge pipe. The drive shaft is provided with a protrusion, and the driven gear is provided with a groove that mates with the protrusion. The protrusion slides through the groove. The driving gear is fixedly sleeved on the main shaft. The driven gear and the driving gear form a gear engagement.

[0013] When the main shaft rotates, the drive shaft rotates through the transmission between the drive gear and the driven gear, causing the feeding wheel in the discharge pipe to rotate, thus conveying the material inside the storage box to the outside through the discharge pipe and completing the fertilization operation.

[0014] An adjustment assembly is provided on the driven gear, the adjustment assembly including a mounting block, a directional slide rod and a locking slider; the mounting block is provided on the side of the driven gear, there are two directional slide rods, which are respectively provided at both ends of the mounting block, and the locking slider is slidably provided on the directional slide rod.

[0015] This allows the locking slider to slide back and forth along the length of the directional slider.

[0016] The locking slider has a positioning pin on the side near the drive shaft, and the drive shaft has an engagement positioning hole and a disengagement positioning hole that cooperate with the positioning pin; the end of the directional slider is fixedly provided with a limit end, and a locking spring is provided between the limit end and the locking slider; an unlocking lever is rotatably provided on the mounting block.

[0017] Under the elastic force of the locking spring, the locking slider moves closer to the drive shaft, causing the locating pin to be inserted into the engagement or disengagement locating hole, thus fixing the installation position of the driven gear. Rotating the unlocking lever will make it contact the locking slider, pushing the locking slider to move away from the drive shaft, causing the locating pin to disengage from the engagement or disengagement locating hole. At this time, the setting position of the driven gear on the drive shaft can be moved.

[0018] The storage bin is equipped with a dispersing mechanism; the dispersing mechanism includes a dispersing roller, a shaft, and a transmission chain; the dispersing roller is rotatably mounted inside the storage bin, and a shaft is provided at each end of the dispersing roller. The shaft extends outward through the storage bin, and a support member for supporting the shaft is fixedly mounted on the mounting plate.

[0019] The rotation of the dispersing roller can disperse the fertilizer in the storage box, prevent the discharge pipe from getting blocked, and ensure uniform discharge and stable fertilizer application.

[0020] A drive sprocket is mounted on the shaft, and a sprocket that cooperates with the drive sprocket is mounted on the main shaft. The drive sprocket and the sprocket on the main shaft are connected by a drive chain.

[0021] During the rotation of the main shaft, the dispersing roller shaft inside the storage box is driven to rotate through the transmission chain, which disperses the fertilizer in the storage box, effectively preventing fertilizer from clogging the discharge pipe and ensuring a uniform and stable amount of fertilizer applied.

[0022] The adaptive fertilization component includes a sliding sleeve, an arc plate, a thrust spring, and a pull rod; the sliding sleeve is slidably sleeved on the end of the discharge pipe, and the sliding sleeve is connected to the discharge pipe; the arc plate is disposed on the sliding sleeve at the end away from the discharge pipe, and a discharge port is opened at the bottom end of the sliding sleeve near the arc plate.

[0023] By bringing the curved plate into contact with the crops, the discharge port is moved to the roots of the crops. Users no longer need to repeatedly adjust the direction of the equipment to align with the crops when fertilizing. Through the adaptive fitting structure of the adaptive fertilization component, fertilizer can be accurately delivered to the roots of the crops, greatly improving the accuracy of fertilization.

[0024] The sliding sleeve is provided with a connecting lug, and the discharge pipe is provided with a connecting plate that mates with the connecting lug; one end of the pull rod is fixedly provided on the connecting lug, and the other end of the pull rod slides through the connecting plate and is provided with a limit piece at its end; the thrust spring is provided between the connecting lug and the connecting plate.

[0025] Under the elastic force of the thrust spring, the sliding sleeve can slide on the discharge pipe and fit against the crop, so that the arc plate contacts the crop. When the arc plate contacts the crop, the sliding sleeve stops sliding due to the resistance of the crop, so that the discharge port is accurately aligned with the crop roots, achieving precision fertilization. Users do not need to repeatedly adjust the direction of the equipment to align with the crop when fertilizing. Through the adaptive fitting structure of the adaptive fertilization component, fertilizer can be accurately delivered to the crop roots, greatly improving the accuracy of fertilization.

[0026] In summary, the beneficial effects of the present invention are as follows: 1. This invention features a main shaft that synchronously drives the traveling wheels, dispersing mechanism, and feeding wheels via a motor, enabling synchronized walking and feeding operations for integrated fertilization. It is easy to operate and features a switchable adjustment mechanism, allowing for independent walking without fertilization or simultaneous walking and fertilization. Fertilization start and stop are flexible and controllable, with material output as needed. The dispersing mechanism breaks up clumps of fertilizer, preventing blockage of the discharge pipe and ensuring uniform output and stable fertilization rate.

[0027] 2. An adaptive fertilization component is installed at the end of the discharge pipe. Under the action of the thrust spring in the adaptive fertilization component, the sliding sleeve can slide on the discharge pipe and conform to the crop, so that the arc plate contacts the crop. When the arc plate contacts the crop, the sliding sleeve stops sliding due to the resistance of the crop, so that the discharge port is precisely aligned with the crop roots, achieving precision fertilization. Users do not need to repeatedly adjust the direction of the equipment to align with the crop when fertilizing. Through the adaptive conforming structure of the adaptive fertilization component, fertilizer can be accurately delivered to the crop roots, greatly improving the accuracy of fertilization.

[0028] In summary, this invention can accurately control the amount of fertilizer applied around crops, ensuring uniform and reasonable fertilizer application, improving the crop growth environment, and enhancing the quality of crop growth. Attached Figure Description

[0031] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0032] The first embodiment of the present invention, referred to Figure 1 and Figure 2 As shown, a precision fertilization device for crops is disclosed, comprising a frame 1, wheels 2, a storage bin 5, and a discharge pipe 7. Mounting seats 13 and supporting feet 18 are welded downwards from the bottom of both ends of the frame 1, respectively. The wheels 2 are rotatably mounted on the mounting seats 13. A support base 16 is bolted to the bottom of the frame 1, and a main shaft 4 is rotatably mounted on the support base 16. A fixed platform 14 is bolted to the top of the frame 1, near the mounting seat 13, and a mounting plate 15 is bolted to the end away from the mounting seat 13. A motor 24 for driving the wheels 2 is bolted to the fixed platform 14, and the storage bin 5 is welded to the mounting plate 15. The discharge pipe 7 is welded to the bottom of the mounting plate 15 and communicates with the storage bin 5. The motor 24 is connected to the main shaft 4 via a belt 241.

[0033] The traveling wheel 2 is equipped with a connecting shaft, and the traveling wheel 2 is rotatably connected to the mounting base 13 through the connecting shaft. A driven transmission wheel 21 is fixedly sleeved on the connecting shaft, and a driving transmission wheel 22 that cooperates with the driven transmission wheel 21 is fixedly sleeved on the main shaft 4. The driven transmission wheel 21 and the driving transmission wheel 22 are connected by a bottom chain 23. In use, the motor 24 drives the main shaft 4 to rotate through the belt 241, and the main shaft 4 drives the traveling wheel 2 to rotate through the bottom chain 23, thereby enabling the equipment to move back and forth to complete the crop fertilization operation.

[0034] Reference Figure 4 As shown, a feeding wheel 3 for quantitatively conveying fertilizer is provided on the upper side inside the discharge pipe 7. A discharge transmission mechanism 8 for driving the feeding wheel 3 to rotate is provided on the discharge pipe 7. The main shaft 4 drives the feeding wheel 3 to rotate through the discharge transmission mechanism 8, so that the fertilizer is evenly conveyed from inside the storage box 5 to the outside through the discharge pipe 7 for fertilizing crops.

[0035] Specifically, refer to Figures 5 to 7 As shown, the discharge transmission mechanism 8 includes a drive shaft 82, a driven gear 83, and a driving gear 84. The drive shaft 82, which drives the feeding wheel 3, is rotatably mounted outside the discharge pipe 7. A support frame 85 is welded onto the discharge pipe 7 to support the drive shaft 82. One end of the drive shaft 82 passes through the side wall of the discharge pipe 7 and is fixedly connected to the feeding wheel 3. The other end of the drive shaft 82 is rotatably mounted on the support frame 85.

[0036] A protrusion 821 is integrally formed and protrudes outward from the drive shaft 82. A groove 831 is formed on the driven gear 83 to cooperate with the protrusion 821. The protrusion 821 slides through the groove 831, allowing the drive shaft 82 to rotate synchronously with the driven gear 83. The driving gear 84 is fixedly sleeved on the main shaft 4, and the driven gear 83 and the driving gear 84 form a gear engagement. When the main shaft 4 rotates, the drive shaft 82 is driven to rotate through the transmission between the driving gear 84 and the driven gear 83, causing the feeding wheel 3 in the discharge pipe 7 to rotate, thus conveying the material inside the storage box 5 outward through the discharge pipe 7 to complete the fertilization operation.

[0037] The driven gear 83 is provided with an adjustment component 86. By operating the adjustment component 86, the installation position of the driven gear 83 on the drive shaft 82 can be adjusted so that the driven gear 83 and the driving gear 84 can be engaged or disengaged. Thus, when fertilization is not required, the engagement between the driven gear 83 and the driving gear 84 can be disconnected, so that the discharge pipe 7 will not fertilize when the main shaft 4 rotates.

[0038] The adjusting assembly 86 includes a mounting block 861, a directional slide rod 863, and a locking slider 862. The mounting block 861 is welded to the side of the driven gear 83. Two directional slide rods 863 are welded to the two ends of the mounting block 861, respectively. The locking slider 862 is slidably mounted on the directional slide rod 863. A locating pin 866 is welded to the end of the locking slider 862 near the drive shaft 82. The drive shaft 82 has an engagement locating hole 823 and a disengagement locating hole 822 that cooperate with the locating pin 866. A limiting end 864 is welded to the end of the directional slide rod 863. A locking spring 865 is provided between the limiting end 864 and the locking slider 862, and the locking spring 865 is sleeved on the directional slide rod 863. Under the elastic force of the locking spring 865, the locking slider 862 moves closer to the drive shaft 82, causing the locating pin 866 to be inserted into the engagement locating hole 823 or the disengagement locating hole 822, fixing the installation position of the driven gear 83. When the locating pin 866 is inserted into the engagement locating hole 823, the driven gear 83 and the driving gear 84 form a gear engagement; when the locating pin 866 is inserted into the disengagement locating hole 822, the driven gear 83 and the driving gear 84 are disengaged.

[0039] An unlocking lever 867 is rotatably mounted on the mounting block 861. Rotating the unlocking lever 867 allows it to contact the locking slider 862, pushing the locking slider 862 to move away from the drive shaft 82. This causes the positioning pin 866 to disengage from the engagement positioning hole 823 or the disengagement positioning hole 822, allowing the driven gear 83 to be moved from its position on the drive shaft 82. A push rod 12 is welded obliquely upward at the end of the frame 1 away from the traveling wheel 2 for easy gripping and use by the user.

[0040] When fertilizing crops, first turn the unlocking lever 867 to unlock the adjusting component 86 structure, move the driven gear 83 to disengage the driven gear 83 from the driving gear 84, and adjust the positioning pin 866 to the position of the corresponding separation positioning hole 822. Then turn the unlocking lever 867 again to release the abutment between the unlocking lever 867 and the locking slider 862. Under the elastic force of the locking spring 865, the positioning pin 866 is inserted into the separation positioning hole 822 to fix the position of the driven gear 83.

[0041] The motor 24 is started, driving the walking wheels 2 to rotate. The user holds the push rod 12 and moves the equipment to the area to be fertilized. Then, the adjustment component 86 is operated again to adjust the driven gear 83 to engage with the driving gear 84, and it is then fixed in place by the positioning pin 866. At this time, the main shaft 4 drives the walking wheels 2 to rotate while simultaneously driving the feeding wheel 3 to discharge fertilizer. The fertilizer is continuously and quantitatively output through the discharge pipe 7, fertilizing the crops. This fertilization method can precisely control the amount of fertilizer applied around the crops, effectively improving the quality of crop growth.

[0042] The second embodiment of the present invention, referred to Figure 3 As shown, a dispersing mechanism 6 for dispersing fertilizer is provided inside the storage bin 5. The dispersing mechanism 6 includes a dispersing roller 61, a shaft 62, and a transmission chain 63. The dispersing roller 61 is rotatably mounted inside the storage bin 5, and shafts 62 are respectively provided at both ends of the dispersing roller 61. The shafts 62 extend outward through the storage bin 5, and a support member 17 for supporting the shafts 62 is fixedly mounted on the mounting plate 15. A transmission sprocket 621 is driven on the shaft 62, and a sprocket that cooperates with the transmission sprocket 621 is driven on the main shaft 4. The transmission sprocket 621 and the sprocket on the main shaft 4 are connected by the transmission chain 63.

[0043] During the rotation of the main shaft 4, the dispersing roller shaft 61 inside the storage box 5 is driven to rotate through the transmission chain 63, which disperses the fertilizer in the storage box 5, effectively preventing the fertilizer from clogging the discharge pipe 7, and ensuring that the amount of fertilizer applied is uniform and stable.

[0044] The third embodiment of the present invention, referred to Figure 4 As shown, an adaptive fertilization component 9 is provided at the bottom of the discharge pipe 7, which can accurately deliver fertilizer to the roots of crops. The adaptive fertilization component 9 includes a sliding sleeve 91, an arc-shaped plate 92, a thrust spring 95, and a pull rod 96. The sliding sleeve 91 is slidably sleeved on the end of the discharge pipe 7 and is connected to the discharge pipe 7; the arc-shaped plate 92 is welded to the end of the sliding sleeve 91 away from the discharge pipe 7, and a discharge port 912 is opened at the bottom of the sliding sleeve 91 near the arc-shaped plate 92.

[0045] A connecting lug 911 is welded onto the sliding sleeve 91, and a connecting plate 71 that mates with the connecting lug 911 is welded onto the discharge pipe 7. One end of the pull rod 96 is fixedly welded to the connecting lug 911, and the other end of the pull rod 96 slides through the connecting plate 71 and has a limit piece at its end. The thrust spring 95 is disposed between the connecting lug 911 and the connecting plate 71 and is sleeved on the pull rod 96.

[0046] Under the elastic force of the thrust spring 95, the sliding sleeve 91 can slide on the discharge pipe 7 and fit against the crop, so that the arc plate 92 contacts the crop. When the arc plate 92 contacts the crop, the sliding sleeve 91 stops sliding due to the resistance of the crop, so that the discharge port 912 is precisely aligned with the crop roots, achieving precision fertilization. Users do not need to repeatedly adjust the direction of the equipment to align with the crop when fertilizing. Through the adaptive fitting structure of the adaptive fertilization component 9, fertilizer can be accurately delivered to the crop roots, greatly improving the accuracy of fertilization.

[0047] This invention features a main shaft 4 that synchronously drives the traveling wheels 2, the dispersing mechanism 6, and the feeding wheels 3 via a motor 24. This integrated approach to fertilization, with synchronized movement and material feeding, makes operation convenient. An adjustable component 86 allows for independent movement without fertilization or simultaneous movement and fertilization, providing flexible and controllable start / stop for on-demand material discharge. The dispersing mechanism 6 breaks up clumps of fertilizer, preventing blockage of the discharge pipe 7 and ensuring uniform discharge and stable fertilization rates.

[0048] An adaptive fertilization component 9 is configured at the end of the discharge pipe 7, which can automatically conform to the crop and deliver fertilizer to the crop roots without repeatedly adjusting the equipment position, ensuring precise fertilization positioning.

[0049] This invention can accurately control the amount of fertilizer applied around crops, ensuring uniform and reasonable fertilizer application, improving the crop growth environment, and enhancing the quality of crop growth.
