The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0025] A negative pressure pneumatic seed suction and spraying device comprises a seed dropper 5, a fan 6 and a spraying channel.

[0026] The seeding channel includes an air intake section 1, a seed transport section 2, a seed suction section 3 and a seed spraying section 4. Among them, the seed suction section 3 includes a main seeding pipe 31 and an auxiliary seeding pipe 32. The bottom end of the main seeding pipe 31 is vertically arranged and connected to the fan 6, the top end of the main seeding pipe 31 is connected to the bottom end of the main seeding pipe 31 through a bending portion 33, and the top end of the main seeding pipe 31 is tilted forward and connected to the rear end of the seed spraying section 4, and the front end of the auxiliary seeding pipe 32 is connected to the bending portion 33.

[0027] The fan 6 of this embodiment is a high-speed fan, which provides power for the air of the main sowing pipe 31, increases its fluid velocity, makes the fluid velocity of the auxiliary sowing pipe 32 less than the fluid velocity of the main sowing pipe 31, and generates negative pressure in the main and auxiliary sowing pipes 32, which forms a force on the seeds reaching the seed suction section 3, pushes the seeds from the auxiliary sowing pipe 32 to the main sowing pipe 31, and achieves the seed suction effect. At the same time, the power provided by the fan 6 pushes the seeds in the main sowing pipe 31 into the spraying section 4, and sprays out from the front end of the spraying section 4 to complete the sowing.

[0028] In this embodiment, the seed spraying section 4 is a straight pipe, which provides a fixed track for the seeds pushed by the fan 6, guides the seeds to be sprayed along the fixed track and direction under the action of air force, and finally reaches the sowing area.

[0029] Preferably, the auxiliary sowing pipe 32 is arranged parallel to the top of the main sowing pipe 31, so that the resistance of the seeds entering the main sowing pipe 31 from the auxiliary sowing pipe 32 is reduced, and the diameter of the auxiliary sowing pipe 32 is smaller than the diameter of the main sowing pipe 31. After entering the main sowing pipe 31, the seeds are more dispersed, thereby allowing the seeds to be sprayed over a larger range.

[0030] The rear end of the air intake section 1 is connected to the outside air, the rear end of the seed transport section 2 is connected to the front end of the air intake section 1, and the front end of the seed transport section 2 is connected to the rear end of the auxiliary spraying pipe 32. A seed drop tube 11 is provided on the top side wall of the air intake section 1, and the top of the seed drop tube 11 is connected to a seed drop device 5. The seed drop device 5 is used to control the falling speed of the seeds and send the seeds into the air intake section 1. After that, due to the negative pressure generated in the main spraying pipe 31, the seeds are sucked into the seed suction section 3 through the air intake section 1 and the seed transport section 2.

[0031] In this embodiment, the seed transport section 2 is a bendable hose. In addition, the front end of the seed transport section 2 is higher than the rear end of the seed transport section 2, and the front end diameter of the seed transport section 2 is smaller than the rear end diameter of the seed transport section 2, so that the gas flow rate at the front end of the seed transport section 2 is greater than the gas flow rate at the rear end of the seed transport section 2, and negative pressure is generated at the front end of the seed transport section 2, further providing thrust for the seeds to move forward.

[0032] Similarly, the diameter of the air intake section 1 gradually decreases from the rear end to the front end, generating negative pressure at the front end of the air intake section 1, further providing forward thrust to the seeds and the external air entering the air intake section 1.

[0033] In addition, a seed adjustment plate 12 is provided in the air intake section 1. The seed adjustment plate 12 is arranged below the seed drop tube 11 and extends forward and backward. The front end of the adjustment plate is tilted downward, and the bottom end of the seed drop tube 11 is also tilted forward, which is used to control the trajectory and direction of the seeds so that the seeds move forward in a directed manner after entering the air intake section 1.

[0034] This embodiment uses air power to spray seeds to a designated area, has a simple structure, and is applicable to a wide range of areas. It also reduces damage to original vegetation, shortens the recovery period, and reduces sowing costs.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
