Description

Technical Field

[0001] The utility model relates to the field of sowing equipment, in particular to an integrated assembly and disassembly type sesame sowing device. Background Art

[0002] Sesame seeds are small, and the sowing effect is often affected by sesame seeds getting stuck in the gaps of the seeding assembly. During the sowing operation, the seeding assembly needs to be frequently disassembled from the seeder bracket for cleaning to ensure the sowing quality. The utility model patent with the authorization announcement number CN 219182040U discloses a quick-detachable sesame sowing mechanism driven by a synchronous shaft, in which a driven gear is installed on the driving shaft of the seeding assembly, and a driven gear meshing with the driving gear is installed on the base through a spline shaft. Therefore, when the seeding assembly and the base are disassembled and assembled, the driving gear and the driven gear can be automatically separated or engaged to realize the removal or assembly of the seeding assembly. However, a seeder is usually designed with multiple seeding assemblies for efficient multi-row sowing. The above-mentioned connection structure can only be disassembled or assembled one by one, which makes the operation process more cumbersome, time-consuming and labor-intensive.

[0007] Preferably, the inner side surface of the end of the upper crossbeam is connected to a horizontal axis through a support plate. The horizontal axis is designed as a height-adjustable structure on the support plate. The direction of the horizontal axis is consistent with the length direction of the hexagonal driven shaft, and the chain support forms a tensioning structure on the horizontal axis.

[0008] Preferably, a support roller corresponding to the position of the chain is rotatably connected to the horizontal axis, and an annular groove is provided on the surface of the support roller.

A driving sprocket 241 is correspondingly provided at the end of the hexagonal driving shaft 24, and a chain 27 is connected between the driving sprocket 241 and the driven sprocket 231. A power source for driving the hexagonal driving shaft 24 to rotate is installed on the seeder.

[0019] A circular allowance hole 252 is provided at the inner end of the transverse notch 251, and the circular allowance hole 252 is coaxial with the hexagonal driven shaft 23. The size of the transverse notch 251 is larger than the cross-sectional size of the hexagonal driven shaft 23, and the size of the circular allowance hole 252 is larger than the size of the transverse notch 251. The circular allowance hole 252 can lift the hexagonal driven shaft 23 upward to a certain height, so that the seeding assembly 22 can be lifted to a certain height from the seeding assembly base 21 and detached from it.

[0020] A plate-shaped base 291 is provided on the surface of the upper crossbeam 29, and the seeding assembly base 21 is mounted on the surface of the plate-shaped base 291 by screws. The plate-shaped base 291 provides stable support for the seeding assembly base 21 to ensure stability.

[0021] When the sowing device of this embodiment is working, the power source on the seeder drives the hexagonal driving shaft 24 to rotate, and the hexagonal driving shaft 24 drives the hexagonal driven shaft 23 to rotate through the chain 27, and the hexagonal driven shaft 23 drives several seeding components 22 to run synchronously for seeding. When disassembly and maintenance are required after the seeding operation, the chain 27 is first loosened, and then the upper bearing seat 253 on each L-shaped support 25 is loosened in turn, and the hexagonal driven shaft 23 is lifted up to a certain height. Each seeding component 22 is raised to a certain height from its respective seeding component base 21 to achieve separation between the two, and then the hexagonal driven shaft 23 is moved horizontally to pull it out of the horizontal notch 251.

At the same time, the annular groove 282 can act as a horizontal limiter to prevent the chain 27 from swinging, ensure the driving effect between the sprockets, and provide stable power for the seeding assembly 22. The support roller 281 is made of plastic to prevent damage to the chain 27 during the rolling tensioning process of the support roller 281.
