Abstract
Description
Technical Field
[0001] This utility model relates to the field of seeder technology, specifically to a hand-cranked anti-jamming seeder. Background Technology
[0002] A seeder is a planting device that breaks up and spreads materials. A commonly used model is the centrifugal seeder, where seeds fall from a seed box onto a spreading wheel and are spread tangentially under centrifugal force. It can also spread powdery or granular fertilizers, lime, and other materials.
[0003] When existing seeders spread materials, some of the material particles are too small, making it easy for the material to get into the shaft that drives the spreading wheel, causing the shaft to jam and affecting the stability of the spread material. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hand-cranked anti-jamming seeder that can prevent the shaft from jamming, thereby improving the stability of the sown material.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hand-cranked anti-jamming seeder, comprising a material box, a material trough inside the material box, a base below the material box, a rotating shaft between the material box and the base, a spreading disc fitted around the outer periphery of the rotating shaft, a material inlet at the bottom of the material box, the material in the material trough entering the spreading disc through the material inlet, being dispersed and spread out by the rotation of the spreading disc, and a sealing component on the side of the rotating shaft facing the material inlet, the sealing component being used to prevent material from entering the rotating shaft to avoid jamming.
[0006] The present invention is further configured such that: the bottom of the material box is provided with a downwardly extending positioning rod; the rotating shaft includes a fixed part and a rotating part; the rotating part can rotate around the fixed part; the outer periphery of the fixed part is fitted and fixed to the outer periphery of the positioning rod; the center of the spreading disc is provided with a positioning protrusion extending to both sides; the positioning protrusion is provided with a positioning groove; and the bottom end of the rotating part is fixed in the positioning groove.
[0007] The present invention is further configured such that: the sealing assembly includes a dustproof gasket and an O-ring, the dustproof gasket is disposed at the junction of the fixing part and the positioning rod, the outer periphery of the fixing part is provided with an annular groove, and the O-ring is embedded in the annular groove.
[0008] The present invention is further configured such that: a gearbox and a manual crank are provided on the outside of the material box, and the manual crank drives the rotating shaft to rotate through the gearbox.
[0009] The present invention is further configured such that: one end of the manual crank extends into the gearbox as an extension end, the extension end is fitted with a drive gear, the gearbox is provided with a rotatable conical gear disk, the center of the conical gear disk is provided with a driven gear that meshes with the drive gear, the outer side of the conical gear disk is provided with a conical gear that meshes with the conical gear disk, the bottom of the conical gear is provided with a transmission gear, and the outer periphery of the rotating part is provided with teeth that mesh with the transmission gear.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] When spreading materials, after the materials are poured into the trough, the materials in the trough enter the spreading disc through the material inlet. The spreading disc is then dispersed by the paddle plate as it rotates, and the centrifugal force generated causes the materials to be evenly spread outwards. Furthermore, by setting a sealing component on the side of the rotating shaft facing the material inlet, the material can be prevented from entering the rotating shaft when it rotates, thus avoiding the rotating shaft from jamming and improving the stability of spreading materials.

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] like Figures 1 to 5 As shown, this utility model discloses a hand-cranked anti-jamming seeder, including a material box 2, a material trough inside the material box 2, a base 1 below the material box 2, a rotating shaft 3 between the material box 2 and the base 1, a spreading disc 4 fitted around the outer periphery of the rotating shaft 3, and multiple evenly distributed paddles on the surface of the spreading disc 4. The bottom of the material box 2 has a material inlet 21. When spreading the material, after the material is poured into the material trough, the material in the material trough enters the spreading disc 4 through the material inlet 21. The material is dispersed by the paddles through the rotation of the spreading disc 4 and is spread outward by the centrifugal force generated. A sealing component is provided on the side of the rotating shaft 3 facing the material inlet 21. The sealing component is used to prevent the material from entering the rotating shaft 3 to avoid jamming of the rotating shaft 3, thereby improving the stability of spreading the material.
[0021] In this embodiment, a downwardly extending positioning rod 5 is provided at the bottom of the material box 2. The positioning rod 5 has an internal hexagonal cross-section. The rotating shaft 3 includes a fixed part 31 and a rotating part 32. The rotating part 32 is fitted onto one end of the fixed part 31 so that the rotating part 32 can rotate around the fixed part 31. The outer periphery of the fixed part 31 is fitted and fixed to the outer periphery of the positioning rod 5. The center of the spreading disc 4 is provided with a positioning protrusion 41 extending to both sides. The positioning protrusion 41 has a positioning groove 411 inside. The positioning groove 411 has an internal hexagonal cross-section. The bottom end of the rotating part 32 is fixed in the positioning groove 411. Through the setting of the positioning rod 5 and the positioning protrusion 41, the fixed part 31 and the rotating part 32 can be fitted onto the outer periphery of the positioning rod 5 and inserted into the positioning groove 411 in the positioning protrusion 41, respectively. This allows the two ends of the rotating shaft 3 to be subjected to force, preventing the axis of the rotating shaft 3 from shifting during the rotation of the rotating part 32, thereby ensuring the stability of the rotating part 32 when rotating.
[0022] In this embodiment, the sealing assembly specifically includes a dustproof gasket 6 and an O-ring seal 7. The dustproof gasket 6 is disposed at the junction of the fixed part 31 and the positioning rod 5. The fixed part 31 has an annular groove 311 on its outer periphery. The O-ring seal 7 is embedded in the annular groove 311. Through the deformation generated by the compression of the dustproof gasket 6 and the O-ring seal 7, the fixed rod can be tightly pressed, preventing external dust and other impurities from entering the rotating part 32 below and causing the rotating part 32 to jam. Furthermore, since the rotating shaft 3 is composed of the fixed part 31 and the rotating part 32, when the spreading disc 4 is driven to rotate, the fixed part 31 will not rotate with the rotating part 32, thereby ensuring that the sealing assembly is stationary relative to the fixed part 31. This reduces the wear on the sealing assembly and ensures the stability of the long-term seal.
[0023] In this embodiment, the rotation of the spreading disc 4 is driven by the interaction between the gearbox 8 and the manual crank 9 located on the outside of the material box 2. Specifically, one end of the manual crank 9 extends into the gearbox 8 as an extension end, and a drive gear 81 is fixedly fitted onto the extension end. A rotatable conical gear disk 82 is provided inside the gearbox 8, that is, the conical gear disk 82 is rotatably connected to the inside of the gearbox 8. A driven gear 821 that meshes with the drive gear 81 is provided at the center of the conical gear disk 82. A conical gear 83 that meshes with the conical gear disk 82 is provided on the outside of the conical gear disk 82. A transmission gear 831 is provided at the bottom of the conical gear 83. Teeth 8 are provided on the outer periphery of the rotating part 32 that mesh with the transmission gear 831. 4. By adopting the above design, after the manual crank 9 is rotated, the driving gear 81 can be rotated. As the driving gear 81 rotates, the bevel gear disk 82 can rotate through the driven gear 821 meshing with the driving gear 81. The rotation of the bevel gear disk 82 can drive the bevel gear 83 to rotate. Then, through the transmission gear 831 integrally set with the bevel gear 83 meshing with the teeth 84 on the outer periphery of the rotating part 32, the rotating part 32 can be driven to rotate. In this way, the driving force generated by the rotation of the manual crank 9 can be converted into the power to drive the rotating part 32 to rotate through the gearbox 8. Furthermore, the above design can make the overall structure more compact and facilitate its widespread use.
[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
