Seeders are the main tool for agricultural production. With the rapid development of facility agriculture, new requirements are put forward for its supporting sowing equipment. Traditional crop seed sowing uses equipment to dig trenches, people to sow seeds and cover the soil.

[0003] After searching, it is proposed in an agricultural corn sowing device with patent application number CN202321631401.8 that "the utility model uses a feeder. When in use, the corn seeds in the storage compartment will enter the large feeder trough or the small feeder trough.

[0024] The quantitative seeding device 3 includes a feeding box 301, the back side of which is fixedly connected to the front side of the moving plate 203, a storage cylinder 302 is fixedly installed on the top of the feeding box 301, a feeding valve is provided at the bottom of the storage cylinder 302, and the output port of the feeding valve is located inside the feeding box 301, a lifting arc plate 304 is fixedly installed on the inner wall of the feeding box 301, and a rotating shaft 307 is rotatably connected to the inner wall of the feeding box 301 through a driving motor 306, and the rotating shaft 307 is located at the center of the inner side of the lifting arc plate 304;

[0025] A driving slot 308 is formed inside the rotating shaft 307 . A placement block 310 is slidably connected to the inner wall of the driving slot 308 via a sliding rod 309 . The placement block 310 is located at the opening of the driving slot 308 .

[0026] By setting up a quantitative sowing device 3, seeds fall from the storage tube 302 to the rotating shaft 307, and then the output flow of seeds through the placement block 310 is controlled by controlling the rotation speed of the driving motor 306, thereby adjusting the outflow quantity of seeds. In addition, the placement block 310 can be adjusted in position inside the driving groove 308 through the sliding rod 309, so that the device can adjust the planting density according to the planting needs, so that the device can meet the planting needs.

[0027] Specifically, a diverter arc plate 303 is fixedly installed on the inner wall of the unloading box 301, and the diverter arc plate 303 is located above the rotating shaft 307. The top of the lifting arc plate 304 is fixedly connected with a slope bar 305, and the placement directions of the two slope bars 305 are opposite.

[0028] In this embodiment, the seeds can be diverted and guided by the diverter arc plate 303 and the slope strip 305 , thereby preventing the seeds from directly colliding with the rotating shaft 307 .

[0029] Specifically, two arc blocking plates 311 are fixedly installed on the outer side of the placement block 310 , and the arc blocking plates 311 are located on the inner side of the opening of the driving groove 308 .

[0030] In this embodiment, the blocking arc plate 311 is provided to shield the opening of the driving groove 308 while the placement block 310 moves, thereby preventing seeds from falling into the driving groove 308 when the placement block 310 slides inside the driving groove 308.

[0031] When in use, the device is first moved to a designated position by the mobile base 1, and then the intervals between the unloading boxes 301 and the intervals between the placement blocks 310 are adjusted according to the types of seeds stored in the storage cylinder 302;

[0032] The movable plate 203 is pulled in advance, so that the movable plate 203 drives the unloading box 301 to slide horizontally on the inner side of the adjustment frame 201 along the direction of the cross bar 202. When each movable plate 203 moves to a suitable interval, the hinge pin 204 is screwed into the limiting groove 205, so that the hinge pin 204 can limit the movable plate 203;

[0033] Then, the placement block 310 is pulled, so that the placement block 310 drives the two blocking arc plates 311 to slide along the opening of the driving groove 308 through the sliding rod 309, so that the relative position between the placement block 310 and the rotating shaft 307 is adjusted, and the intervals between the placement blocks 310 are also adjusted. In addition, since the setting of the blocking arc plates 311 can shield the opening of the driving groove 308 while the placement block 310 moves, it is avoided that when the placement block 310 slides inside the driving groove 308, the seeds will not fall into the driving groove 308;

[0034] After the interval adjustment of the seeds falling is completed, the discharge valve at the bottom of the storage tube 302 is opened, so that the seeds fall from the storage tube 302 and slide along the diverter arc plate 303 and the slope strip 305, so that the seeds finally fall into the placement block 310 set inside the rotating shaft 307, and then the drive motor 306 is started, so that the movable end of the drive motor 306 drives the rotating shaft 307 to flip, and when the opening of the placement block 310 is opposite to the ground, the seeds will automatically fall from the placement block 310 into the soil.

[0035] In summary, the agricultural sowing device, by providing the interval adjustment device 2, can use the movable plate 203 to drive the quantitative sowing device 3 to slide horizontally on the inner side of the adjustment frame 201 along the direction of the cross bar 202, so that the intervals between the quantitative sowing devices 3 can be adaptively adjusted, which can adapt to the planting of seeds of different varieties and avoid planting intervals that are too large or too small, thereby achieving uniform sowing of seeds, which is beneficial to improving the quality of sowing, facilitating the germination and growth of seeds, and significantly improving the scope of application of the sowing equipment, thereby improving the practicality of the sowing device;

[0036] By setting up a quantitative sowing device 3, seeds fall from the storage tube 302 to the rotating shaft 307, and then the output flow of seeds through the placement block 310 is controlled by controlling the rotation speed of the driving motor 306, thereby adjusting the outflow quantity of seeds. In addition, the placement block 310 can be adjusted in position inside the driving groove 308 through the sliding rod 309, so that the device can adjust the planting density according to the planting needs, so that the device can meet the planting needs.
