Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of grass seed hole sowing, and more specifically, relates to a small grass seed hole sowing device. Background Technology
[0002] In the agricultural industry, sowing is inevitable. Farmers sowing by themselves is not only inefficient, but also puts a strain on their bodies due to long hours of bending over. The emergence of grass seed sowing devices has not only improved sowing efficiency, but also greatly reduced the labor intensity of farmers. It can sow seeds at precise intervals and depths, which is conducive to the even distribution and good growth of seeds, laying a solid foundation for subsequent field management and a bumper harvest.
[0003] Different grass seeds are of different sizes, and therefore require different sizes of sowing devices. When changing grass seeds, the sowing device also needs to be changed. Each time the grass seed variety is changed, a lot of time is spent disassembling and installing the appropriate sowing device, which seriously affects the sowing efficiency. Moreover, due to the rich variety of grass seed varieties, keeping multiple sowing devices in stock to adapt to different grass seeds undoubtedly greatly increases equipment costs and management difficulty.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a small grass seed hole sowing device in order to achieve a more practical purpose. Utility Model Content

A long plate is disposed between the second arc-shaped plate and the first arc-shaped plate. One end of the long plate is connected to the second arc-shaped plate, and the other end of the long plate is connected to the first arc-shaped plate. An air box is fixedly disposed on the side of the fixed block facing the long plate. A second air chamber is disposed inside the air box.

The long plate drives the second arc-shaped plate to move, and the second arc-shaped plate drives the third annular plate to move, thereby driving all the first arc-shaped plates to move. By sliding the first arc-shaped plates, the size of the opening on the second annular plate is controlled, thus changing the opening size according to the size of the grass seed. This allows the device to be adjusted according to the size of the grass seed, regardless of its size. This enables the device to be used in various applications without having to disassemble the sowing device multiple times. This device not only improves sowing efficiency but also saves costs, eliminating the need to purchase multiple sowing devices.
[0019] The fixed block has a ramp at the opening, which reduces the size of the entry point when the first arc plate blocks the opening. This achieves consistency in both the longitudinal and lateral directions, ensuring that no excess grass seeds enter the seeding tray and avoiding the situation of multiple seeds in one pit during sowing. This improves the sowing quality and uniformity, and provides a guarantee for the growth of crops in the later stage. Attached Figure Description

[0046] Specific usage method of this utility model:
[0047] Grass seeds enter the seed inlet 15 from the outside, and then enter the seeding device from the seed inlet 15.
[0048] When the grass seed is not suitable for the current size of the sowing device, the piston 22 is pushed to slide, and the piston 22 pushes the gas in the first air chamber 23 into the second air chamber 36.

[0049] Meanwhile, the fixing block 25 has a ramp at the opening, which reduces the size that can be entered when the first arc plate 31 blocks the opening, achieving consistency in the longitudinal and lateral directions, preventing multiple grass seeds from entering the sowing device and affecting subsequent sowing, and avoiding the situation of multiple seeds in one pit.
[0050] After adjusting the device, place it on the ground and push the push rod 12. The push rod 12 will drive the device forward, and the track 14 will contact the ground. The first rotating shaft 18 will rotate, which will drive the track 14 to move. The movement of the track 14 will drive the second rotating shaft 21 to rotate. The second rotating shaft 21 will drive the internal first annular plate 24 to rotate, thereby driving the rotation of the internal seeding device to achieve seeding.
[0051] At the same time, when the first arc plate 31 slides, the first sliding plate 29 will slide inside the first cavity 39, so that the first sliding plate 29 always keeps in contact with the fixed block 25, thus preventing grass seeds from falling into the device and causing blockage and damage to the inside of the device.
