[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1

[0024] See also Figures 1-4 A seedling sowing density controllable seeding device includes a base 100. A powerful motor body 200, a storage box and a conveyor belt are installed on the top of the base 100. The top of the powerful motor body 200 is transmission-connected to a negative pressure fan body 300. A negative pressure plate 400 is installed on the side of the negative pressure fan body 300. A seeding head 500 is installed at the bottom of the negative pressure plate 400. An interception net 600 is installed inside the seeding head 500. When the negative pressure fan body 300 is activated, a sufficient amount of seeds can be adsorbed in the seeding head 500 through the negative pressure plate 400.

[0025] The bottom of the seeding head 500 is equipped with an anti-drop assembly 700. This assembly includes an air pressure device 701, which extends through the seeding head 500. The air pressure device 701 is composed of a rigid air pressure chamber and an air pressure hose, and is fixedly connected to the negative pressure plate 400. One end of the air pressure device 701 is fixedly connected to an elastic airbag 1 702. When a sufficient amount of seeds are adsorbed into the seeding head 500, the seeds are subjected to sufficient pressure, squeezing the elastic airbag 1 702, causing it to deform. The gas stored in the elastic airbag 1 702 is then squeezed into the air pressure device 701, increasing the pressure within the air pressure device 701. The other end of the air pressure device 701 is slidably connected to a curved rod 703. As the pressure within the air pressure device 701 increases, the curved rod 703, which is slidably connected to the air pressure device 701, moves. The bottom of the negative pressure plate 400 is rotatably connected to a torsion spring rod 704. A transmission rod 705 is fixedly connected to the outside of the torsion spring rod 704. A protective plate 706 is fixedly connected to the side of the transmission rod 705. The protective plate 706 is located on the side of the arc rod 703 and is fixedly connected to the arc rod 703. When the arc rod 703 moves, the torsion spring rod 704 and the negative pressure plate 400 are rotatably connected, and the torsion spring rod 704 and the protective plate 706 are connected via the transmission rod 705. As a result, the arc rod 703 drives the transmission rod 705 to rotate, and the transmission rod 705 drives the protective plates 706 to rotate. The protective plates 706 on both sides rotate to the bottom of the seeding head 500, thereby preventing seeds from falling during the transfer process and reducing the impact on the use of the device. When the seeds stop being adsorbed in the seeding head 500, the seeds fall naturally under the action of their own gravity, and the elastic airbag 702 loses its restriction and then resets itself, so that the anti-drop component 700 is reset under the action of the torsion spring rod 704 for the next use.

[0026] When in use, the negative pressure fan body 300 is activated, and a sufficient amount of seeds can be adsorbed in the seeding head 500 through the negative pressure plate 400. At this time, the seeds are subjected to sufficient pressure to squeeze the elastic airbag 1 702, causing the elastic airbag 1 702 to deform. The gas stored in the elastic airbag 1 702 is then squeezed into the air pressure device 701, which increases the pressure in the air pressure device 701, driving the arc rod 703 slidably connected to the air pressure device 701 to move. Due to the rotation connection between the torsion spring rod 704 and the negative pressure plate 400, the torsion spring rod 703 is rotated. 704 and the protective plate 706 are connected by a transmission rod 705, so that the arc rod 703 drives the transmission rod 705 to rotate, and the transmission rod 705 drives the protective plate 706 to rotate, and the protective plates 706 on both sides rotate to the bottom position of the seed-pointing head 500; and when the seeds stop being adsorbed in the seed-pointing head 500, the seeds fall naturally under the action of their own gravity, and the elastic airbag 702 loses its restriction and then resets under its own action, so that the anti-drop component 700 is reset under the action of the torsion spring rod 704.

[0027] Example 2

[0028] See also Figures 1-4 Based on the first embodiment, an auxiliary assembly 800 is provided on the protective plate 706. The auxiliary assembly 800 includes an air pressure chamber 801. The air pressure chamber 801 is fixedly connected to the protective plate 706 and extends through the protective plate 706. One end of the air pressure chamber 801 is fixedly connected to a second elastic airbag 802. When the protective plates 706 on both sides rotate to the seeding head 500, the second elastic airbag 802 is squeezed, and the gas stored in the second elastic airbag 802 is squeezed into the air pressure chamber 801 to which it is fixed, increasing the pressure in the air pressure chamber 801. The other end of the air pressure chamber 801 is slidably connected to a push plate 803, and a blocking block 804 is fixedly connected to the side of the push plate 803. When the pressure in the air pressure chamber 801 increases, the push plate 803 that is slidingly connected to the air pressure chamber 801 moves, so that the push plate 803 drives the blocking block 804 fixedly connected to it to move, and the blocking block 804 then moves to the gap between the two protective plates 706 to seal, further preventing seeds from falling.

[0029] During use, based on Example 1, when the protective plates 706 on both sides rotate to the seeding head 500, the elastic airbag 2 802 is immediately squeezed, and the gas stored in the elastic airbag 2 802 is immediately squeezed into the air pressure chamber 801 fixedly connected thereto, so that the pressure in the air pressure chamber 801 increases, driving the push plate 803 slidingly connected to the air pressure chamber 801 to move, so that the push plate 803 drives the blocking block 804 fixedly connected thereto to move, and the blocking block 804 immediately moves to the gap between the two protective plates 706 for sealing.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
