Description

Technical Field

[0001] This invention belongs to the field of fertilization devices, specifically a small-scale fertilization device. Background Technology

[0002] Fertilization refers to agricultural techniques that apply fertilizer to the soil or spray it on plants to provide the nutrients needed by the plants and maintain and improve soil fertility. Small-scale fertilization devices are commonly used tools for growers to perform localized fertilization. However, existing small-scale fertilization devices lack depth adjustment mechanisms and can only apply fertilizer to the soil in a fixed manner. Moreover, most of them are direct fertilization methods without mixing effects, which makes it easy for fertilizer to be locally concentrated or unevenly dispersed in the soil. This not only fails to provide nutrients to crops evenly, but may also have an adverse effect on crop root growth due to excessively high local fertilizer concentrations. Therefore, there is an urgent need for a small-scale fertilization device that can solve the above problems. Summary of the Invention

[0003] This invention provides a small-scale fertilization device to overcome the shortcomings of the prior art.

A spiral blade is rotatably mounted inside the tank. A vertical tube is fitted over the spiral blade and fixedly mounted inside the tank. The tank is equipped with a drive mechanism that drives the spiral blade to move up or down. A hopper is fixedly mounted on the tank, and a feed inlet communicating with the hopper is provided on the tank.

[0006] As described above, a small fertilization device includes a drive mechanism comprising a square rod, a square rod fixedly mounted on a spiral blade, a top-closed vertical cylinder fixedly mounted on a tank body, sliding sleeves slidably fitted at both ends of the square rod, the two sliding sleeves sequentially rotatably connecting the tank body and the vertical cylinder, an externally threaded tube fixedly fitted on the square rod, a nut threadedly fitted on the externally threaded tube, the nut fixedly installed inside the vertical cylinder, a drive motor fixedly mounted on the vertical cylinder, the output shaft of the drive motor extending into the vertical cylinder and fixedly mounted with a bevel gear, a coaxial bevel gear also fixedly mounted on the sliding sleeve on the vertical cylinder, the two bevel gears meshing together.

[0007] As described above, in a small fertilizer applicator, a partition is fixedly installed inside the tank, and a discharge port is opened on the partition. The partition is rotatably connected to a sliding sleeve on the tank body. A first gear is fixedly installed on the sliding sleeve on the tank body, and a second gear is meshed with one side of the first gear. The second gear is rotatably installed on the tank body. An annular plate is rotatably installed inside the tank body. The inner circumference of the annular plate is provided with toothed grooves, which mesh with the second gear. An arc-shaped through groove is opened on the annular plate, which can overlap with the inlet or outlet.

[0008] As described above, in a small fertilizer applicator, an insertion hole is provided on the side of the hopper near the feed inlet, and an L-shaped insert plate is slidably provided in the insertion hole.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] A small fertilizer applicator, such as Figure 1 , Figure 2 As shown, the device includes a frame on which a fertilizer applicator is mounted. The fertilizer applicator includes an inverted conical tank 10 with an opening at the bottom. A spiral blade 11 is rotatably mounted inside the tank 10. A vertical tube 12 is fitted over the spiral blade 11 and fixedly mounted inside the tank 10. The vertical tube 12, spiral blade 11, and tank 10 are coaxially arranged. The outer periphery of the vertical tube 12 is fixedly connected to the inner wall of the tank 10 by several connecting rods. The tank 10 is equipped with a drive mechanism to drive the spiral blade 11 to move up or down. A hopper 13 is fixedly mounted on the tank 10, and a feed inlet 14 communicating with the hopper 13 is opened on the tank 10. This invention has a simple structure and ingenious design. By controlling the downward movement distance of the spiral blades 11, the depth of fertilization can be controlled, making it highly adaptable. When the fertilizer falls into the tank 10, the auger formed by the spiral blades 11 and the vertical pipe 12 will repeatedly lift the soil and fertilizer, achieving a mixing effect and improving the uniformity of fertilizer distribution in the soil. This effectively avoids damage to crop roots caused by excessively high local fertilizer concentrations, meets practical needs, and is suitable for widespread application. When using this invention, the fertilization device is moved by the frame. After moving to the designated position, the spiral blade 11 is driven to rotate and move downward by the drive mechanism. By controlling the downward distance of the spiral blade 11, the depth of the drilled soil is controlled. The rotating spiral blade 11 transports the soil into the tank 10. At this time, fertilizer is added through the hopper 13. The fertilizer enters the tank 10 through the feed inlet 14. During the rotation of the spiral blade 11, it cooperates with the vertical pipe 12 to lift the soil and fertilizer in the tank 10. The soil and fertilizer are discharged from the top of the vertical pipe 12 and then lifted again. This process is repeated to achieve the effect of stirring and mixing. After the fertilizer is added, the spiral blade 11 is driven to rotate in the opposite direction and move upward by the drive mechanism, so that it moves back into the tank 10. At the same time, the spiral blade 11 rotates in the opposite direction and discharges the soil mixed with fertilizer in the tank 10 back to its original position, thus completing the fertilization.

[0018] Specifically, such as Figure 1As shown, the driving mechanism in this embodiment includes a square rod 20, which is fixedly mounted on the spiral blade 11. A top-closed vertical cylinder 21 is fixedly mounted on the tank body 10. Sliding sleeves 22 are slidably fitted at both ends of the square rod 20. The inner circumference of the sliding sleeves 22 is also square. The square rod 20 can only slide within the sliding sleeves 22 and cannot rotate. The two sliding sleeves 22 are rotatably connected to the tank body 10 and the vertical cylinder 21 in sequence. The inner wall of the pre-drilled hole on the vertical cylinder 21 is rotatably connected to the outer circumference of the corresponding sliding sleeve 22 through a sealing shaft. The inner wall of the pre-drilled hole on the tank body 10 is rotatably connected to the corresponding sliding sleeve 22 through a sealing bearing. An externally threaded tube 23 is fixedly fitted on the square rod 20, and the externally threaded tube 23 is threaded. The threaded nut 24 is installed inside the vertical cylinder 21. The threaded nut 24, the external threaded tube 23, the sliding sleeve 22, the vertical cylinder 21, and the spiral blade 11 are coaxially arranged. The outer circumference of the threaded nut 24 is fixedly connected to the inner wall of the vertical cylinder 21 by several connecting rods. The drive motor 25 is fixedly installed on the vertical cylinder 21. The output shaft of the drive motor 25 extends into the vertical cylinder 21 and is fixedly installed with a bevel gear 26. A through hole is opened on the side wall of the vertical cylinder 21 for the output shaft of the drive motor 25 to pass through. A mounting plate is fixedly connected to one side of the drive motor 25 and is fixedly installed on the vertical cylinder 21. The sliding sleeve 22 on the vertical cylinder 21 is also fixedly installed with a coaxial bevel gear 26, and the two bevel gears 26 mesh with each other. The drive motor 25 runs, and through the meshing of the two bevel gears 26, it drives the corresponding sliding sleeve 22 to rotate. The sliding sleeve 22 then drives the square rod 20 and the external threaded tube 23 to rotate together. Since the nut 24 cannot rotate, the external threaded tube 23 rotates and moves up or down along the nut 24, and drives the square rod 20 to rotate and slide along the sliding sleeve 22. The square rod 20 then drives the spiral blade 11 to rotate and move up or down.

[0019] Specifically, such as Figure 1As shown, in this embodiment, a partition 30 is fixedly installed inside the tank body 10. A discharge port 31 is provided on the partition 30. The partition 30 is rotatably connected to a sliding sleeve 22 on the tank body 10. The outer periphery of the sliding sleeve 22 is rotatably connected to the inner wall of a pre-drilled hole on the partition 30 via a sealed bearing. The outer periphery of the partition 30 is fixedly connected to the inner wall of the tank body 10. A first gear 32 is fixedly installed on the sliding sleeve 22 on the tank body 10. The first gear 32 is coaxially arranged with the corresponding sliding sleeve 22. A second gear 33 is meshed with one side of the first gear 32. The second gear 33 is rotatably mounted on the tank body 10. The second gear 33 is rotatably connected to the coaxial support rod through the bearing. The support rod is fixedly mounted on the tank body 10. The annular plate 34 is rotatably mounted inside the tank body 10. The outer periphery of the annular plate 34 is rotatably connected to the inner wall of the tank body 10 through the bearing. The annular plate 34 is located between the partition plate 30 and the top side of the tank body 10. The inner periphery of the annular plate 34 is provided with tooth grooves and meshes with the second gear 33. An arc-shaped through groove 35 is opened on the annular plate 34. The arc-shaped through groove 35 can overlap with the inlet 14 or the outlet 31. The rotation of the square rod 20 drives the sliding sleeve 22 on the tank 10 to rotate together. Then, through the first gear 32 and the second gear 33, the annular plate 34 rotates. When the arc-shaped through groove 35 on the annular plate 34 overlaps with the feed inlet 14, the fertilizer in the hopper 13 falls into the arc-shaped through groove 35. Then, the annular plate 34 pushes the fertilizer to move. When the arc-shaped through groove 35 overlaps with the discharge outlet 31, the fertilizer in the arc-shaped through groove 35 falls into the tank 10 and mixes with the soil. The more rotations of the external threaded pipe 23 and the square rod 20, the deeper the spiral blade 11 moves downward. At the same time, the more rotations of the annular plate 34 driven by the sliding sleeve 22, and the more times the arc-shaped through groove 35 overlaps with the feed inlet 14, the more fertilizer is added into the tank 10. This achieves the function of adding more material during deep digging, increasing practicality and making it more convenient to use.

[0020] Furthermore, such as Figure 1 As shown, in this embodiment, the hopper 13 has an insertion hole 40 on the side near the feed inlet 14. An L-shaped insert plate 41 is slidably disposed in the insertion hole 40, which can close the feed inlet 14. A threaded hole is formed on the L-shaped insert plate 41, and a first threaded rod 42 is threadedly installed thereon. The first threaded rod 42 is rotatably mounted on the hopper 13, and one end of the first threaded rod 42 is rotatably connected to the hopper 13 through a bearing with a seat. When the first threaded rod 42 is rotated, since the L-shaped insert plate 41 cannot rotate, the L-shaped insert plate 41 moves axially along the first threaded rod 42, thereby moving closer to or further away from the feed inlet 14, changing the area of ​​obstruction of the feed inlet 14, thereby changing the amount of fertilizer passing through the feed inlet 14, and further adjusting the amount of fertilizer applied.

[0021] Furthermore, such as Figure 1As shown, the frame in this embodiment includes a support plate 50, on which several casters 51 are fixedly mounted, and a push handle 52 is fixedly mounted on one side of the support plate 50. By pushing the support plate 50 with the push handle 52, the frame and fertilizer applicator can be moved via the casters 51.

[0022] Furthermore, such as Figure 1 As shown, in this embodiment, fixing plates 60 are fixedly installed on both sides of the tank 10. A second threaded rod 61 is rotatably installed on the fixing plate 60. One end of the second threaded rod 61 is rotatably connected to the fixing plate 60 via a bearing. A threaded hole corresponding to the second threaded rod 61 is opened on the support plate 50, and the second threaded rod 61 is threadedly installed in the corresponding threaded hole. By rotating the second threaded rods 61 on both sides, the fertilizer applicator can be moved up or down on the frame, thereby adjusting the position of the bottom of the tank 10 above the ground, making it easier to adapt to more terrains and increasing its practicality.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
