Description

Technical Field

[0001] The utility model relates to the field of sesame sowing equipment, in particular to a pressure-adjustable soil sealing roller of a sesame sowing machine. Background Art

[0002] The covering roller of a sesame planter is a crucial component. Its primary function is to cover the soil after sowing, ensuring the sesame seeds are properly buried and providing a favorable growing environment. As the planter moves, the covering roller rotates as the planter moves, pressing down on the soil on both sides of the sowing furrow. The soil collapses and covers the planted seeds, while also leveling the soil to ensure a uniform and compact surface, which is conducive to seed germination and growth.

[0003] The current covering roller is movably mounted on the rear of the frame through a bracket. When the seeder is working, the soil is covered and buried by the pressure exerted by the gravity of the covering roller itself. When encountering soil of different soil qualities or large changes in soil moisture, the pressure exerted by the covering roller on the soil will also change. The current installation method of the covering roller cannot adjust the downward pressure accordingly, resulting in poor soil covering and burying effect, affecting the sowing quality, and needs to be improved.

[0024] Example 1, see attached Figure 1-4 6. A pressure-adjustable soil-sealing roller for a sesame seeding machine, comprising two horizontally arranged frame beams 21, a soil-sealing roller body 22 and an adjusting mechanism 23. A support 211 is provided on the bottom surface of the frame beam, and a movable beam 231 is connected to the support. The two ends of the soil-sealing roller body 22 are rotatably connected between the middle parts of the two movable beams 231 through a roller shaft. When the soil-sealing roller body contacts the ground and moves forward, the soil-sealing roller body 22 rotates and covers the soil due to the friction of the ground; the adjusting mechanism 23 comprises a long screw 232 and a manual wheel 234. The upper part of the long screw is vertically slidably connected to the sliding hole at the end of the frame beam 21. The long screw 2 The lower end of 32 is provided with a U-shaped fork 233, which is mounted on the outer end of the movable beam 231. The U-shaped fork and the movable beam 231 are hinged by a pin shaft 235. The sealing roller body 22 can swing up and down between the two frame beams 21 through the movable beam. The manual wheel 234 is threadedly connected to the long screw 232 at the upper end of the frame beam 21. The middle part of the long screw is equipped with a support spring 236. The upper end of the support spring is against the bottom surface of the frame beam 21, and the lower end is against the upper surface of the U-shaped fork 233. Turning the manual wheel 234 can stretch the screw 232 upward and change the compression amount of the support spring 236.

[0025] Two ear plates 212 are symmetrically provided on both sides of the support 211. The end of the movable beam 231 is hinged between the lower ends of the two ear plates 212 through a transverse axis. The movable beam 231 can rotate relative to the frame beam 21 to adjust the angle between the two. Two vertical long holes 214 are symmetrically provided on the upper part of the ear plate 212. Bolts 215 are installed between the vertical long holes and the support 211. After loosening the bolts 215, the height of the two ear plates on the support 211 can be vertically adjusted, thereby increasing the height adjustment range of the covering roller body.

[0026] An operating platform 27 is provided between the outer ends of the frame beams 21. The operating platform is densely covered with a number of anti-slip holes 271. These dense anti-slip holes can increase the friction of the operating platform. It is safer to work on the operating platform 27 when standing and avoid slipping.

[0027] When the soil sealing roller of this embodiment is working, the soil sealing roller body 22 contacts the ground and moves forward. The soil sealing roller body 22 rotates due to the friction of the ground to cover the soil. During this process, the soil sealing roller body swings up and down between the frame beams through the two movable beams. The long screw 232 connected to the soil sealing roller body 22 slides up and down in the sliding hole on the frame beam 21, and the spring provides top pressure for the soil sealing roller body. If you want to change the downward pressure of the soil sealing roller body 22, turn the manual wheel 234 by hand. The manual wheel 234 pulls the screw 232 upward through the thread, and the angle between the frame beam 21 and the movable beam 231 changes, thereby changing the compression amount of the support spring 236, adjusting the top pressure of the support spring 236 on the soil covering roller, and then changing the pressure applied by the soil covering roller to the soil, so that it can adapt to the soil covering and burying requirements of different soil conditions.

[0028] Example 2, see attached Figure 1 、 5 This embodiment is basically the same as the embodiment, except that: a plurality of annular grooves 221 are provided at equal intervals along the axial direction of the side surface of the soil-covering roller body 22, and a transition arc is provided between the annular grooves and the main body of the soil-covering roller body; the annular grooves 221 can form annular protrusions on the soil-covering roller, and these annular protrusions can increase the lateral squeezing force of the soil-covering roller on the soil, making it easier for the soil to enter the sowing furrow.

[0029] A support cross bar 24 is fixedly connected between the ends of the two movable beams 231, and a scraper 25 is fixedly connected to the support cross bar 24 by a screw 241. A number of arc-shaped plates 251 corresponding to the circular groove 221 are evenly provided on the inner side of the scraper. When the soil-sealing roller 22 rolls to seal the soil, soil will adhere to the circular groove. The arc-shaped plate 251 on the scraper 25 extends into the circular groove to scrape off the adhered soil in time to ensure the soil covering and burying effect.

[0030] The support crossbar 24 is a square rod, tilted toward the earth-sealing roller 22. This allows the curved plate 251 to tilt and extend into the circular groove, reducing the reverse force on the scraper 25 and improving its stability and service life. A sleeved circular shaft 242 is provided at each end of the square rod. A sleeve is provided on the upper surface of the movable beam 231. The shaft fits within the sleeve 26 of the sleeve. This sleeve allows for easy installation and removal of the support crossbar 24, facilitating replacement and maintenance of the scraper 25.
