The air intake box 303 is connected to the exhaust port of the air extraction device 201 through a pipeline; a vibration motor 306 is provided in the inner cavity of the screening box 301, and the vibration motor 306 is used to vibrate the filter screen 302. Impurity outlets 316 and a seed outlet 317 are provided on the right side wall of the screening box 301 from top to bottom in sequence, and the seed outlet 317 is connected to the storage box 4; Please refer to Figure 4 and Figure 5 , an inlet is provided at the top of the screening box 301, and the screening box 301 is connected to the storage box 202 through the inlet. A blanking member 206 is provided in the screening box 301. The blanking member 206 includes an electric telescopic rod and a blocking plate installed on the moving end of the electric telescopic rod. The blocking plate blocks the inlet. By moving the electric telescopic rod with the blocking plate, the inlet can be opened or closed; Please refer to Figure 1 , Figure 2 and Figure 8, the sowing assembly 5 includes a material box 501, a plurality of blanking pipes 502 communicatively arranged at the bottom of the material box 501, a plurality of material plates 503 arranged in the inner cavity of the material box 501, and a plurality of second driving members 504 (electric telescopic rods). The moving end of the second driving member 504 is connected to the material plate 503. The number of material plates 503 corresponds to the number of blanking pipes 502 one by one. The material box 501 is installed on the bottom wall of the mobile device 1. An inlet is provided on the top wall of the material box 501, and the inlet communicates with the discharge port of the storage box 4 (a blocking plate and an electric telescopic rod for driving the blocking plate to move are installed inside the storage box 4. The blocking plate seals the discharge port, and the electric telescopic rod drives the blocking plate to move to control the opening and closing of the discharge port); the plurality of blanking pipes 502 are arranged in sequence along the direction perpendicular to the moving direction of the mobile device 1.

[0019] Working principle: Seed collection: Align the air inlet hood 204 with the ground near the wild plants, and then start the air extraction device 201 to generate negative pressure at the inlet of the air inlet hood 204, so as to suck the seeds on the ground into the inner cavity of the air inlet hood 204 and enter the inner cavity of the storage box 202 through the conduit 203. During the process of collecting seeds, the driving device drives the brush roller 205 to rotate to sweep the ground to move the seeds on the ground, facilitating the air inlet hood 204 to adsorb them; Seed screening: After a period of time, the blanking member 206 works to communicate the storage box 202 with the screening box 301, so that the objects stored inside the storage box 202 enter the screening box 301 and fall above the filter screen 302. Then the blanking member 206 controls the separation of the storage box 202 from the screening box 301; the vibration motor 306 works to vibrate the filter screen 302 to shake off the objects (including seeds) smaller than the aperture of the filter screen 302, filtering out large impurities such as branches, leaves, and soil (remaining above the filter screen 302). The gas discharged by the air extraction device 201 enters the inner cavity of the air inlet box 303 through the pipeline, and enters the screening box 301 through the air inlet and blows towards the seeds passing through the filter screen 302 for air separation (removing light impurities such as empty shells and dust). The generated impurities are discharged from the impurity outlet 316, and the seeds after air separation fall to the bottom of the inner cavity of the screening box 301 and enter the storage box 4 for storage; when the air inlet box 303 blows air to the seeds for air separation, the flow sensor 315 is used to detect the magnitude of the air flow rate. When the air flow rate is lower than the threshold, the controller 305 controls the air pump 304 to start to supplement air into the air inlet box 303 to increase the air flow rate blowing towards the seeds (the increased air flow is precisely controlled according to the magnitude of the air flow rate detected by the flow sensor 315); Sowing: The seeds inside the storage box 4 enter the inner cavity of the material box 501, and the second driving member 504 drives the material plate 503 to move, releasing the blockage of the feed pipe 502, so that the seeds inside the material box 501 fall to the ground in the sowing area through the feed pipe 502. At the same time, the mobile device 1 moves to allow the seeds to continue to fall to the sowing area.

[0020] It should be noted that in order to improve the survival rate after sowing, soil turning equipment and fertilizing and watering equipment are installed on the material box 501. Before sowing, the soil in the sowing area is turned over first, and the land after sowing is fertilized and watered. The processes of soil turning, fertilizing and watering are all existing technologies and will not be described in detail here.

[0021] It should also be noted that the seeds collected in this application refer to seeds that fall to the ground, such as moss, bluegrass, etc.

[0022] In this embodiment, as a further optimized solution, please refer to Figure 2 and Figure 4 A second guide block 309 is provided at the bottom of the inner cavity of the screening box 301, and the top wall of the second guide block 309 is an inclined surface. The seeds after air selection fall onto the top wall of the second guide block 309 and pass through the seed outlet 317 under the action of gravity, so that the seeds are discharged from the seed outlet 317 conveniently; first guide blocks 307 are provided on the inner walls on the left and right sides of the screening box 301, and the two first guide blocks 307 are located between the air inlet and the filter screen 302. The top walls of the two first guide blocks 307 are inclined surfaces. The seeds passing through the filter screen fall onto the inclined surface at the top of the first guide block 307, guiding the seeds so that they are concentrated close to the air inlet, ensuring that the wind from the air inlet is better blown to the seeds of the lower material, thereby increasing the effect of air selection.

[0023] In this embodiment, as a further optimized solution, please refer to Figure 2 and Figure 4 A guide plate 308 is provided on the right inner wall of the screening box 301, the left end of the guide plate 308 is tilted downward, the right end of the guide plate 308 is tilted downward, and the right end of the guide plate 308 is flush with the impurity outlet 316, and a deflector 313 is provided on the right wall of the screening box 301, the deflector 313 covers the impurity outlet 316, and openings are provided on both sides of the deflector 313, and the two openings are respectively located on the left and right sides of the moving direction of the mobile device 1; during the air selection process, when some seeds fall to the left side of the guide plate 308, due to the downward tilt of the left side of the guide plate 308, the seeds will not be guided and discharged by the guide plate 308, and the guide plate 308 can hold the impurities generated by the screening and guide the impurities to be discharged from the impurity outlet 316, and the deflector 313 guides the impurities discharged from the impurity outlet 316 to the left and right sides of the moving direction of the mobile device 1.

[0024] In this embodiment, as a further optimized solution, please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 . A chute 311 (the chute 311 is horizontally arranged) is formed on the inner side wall of the screening box 301. A slider 318 is slidably arranged in the inner cavity of the chute 311. A moving plate 310 is arranged on the slider 318. The moving plate 310 is located directly above the filter screen 302. A first driving member 320 is installed on the screening box 301. The first driving member 320 includes a nut sleeve slidably arranged in the inner cavity of the chute 311, a screw rod screwed in the nut sleeve, and a motor for driving the screw rod to rotate. A slot is formed on the right side wall of the slider 318. A magnetic block 319 (the magnetic block 319 can move left and right in the slot, but the magnetic block 319 is not separated from the slot) is slidably arranged in the inner cavity of the slot. The nut sleeve is connected to the right side wall of the magnetic block 319. A storage groove is formed at the bottom of the moving plate 310. A pushing member 322 (such as a push plate, the push plate can be magnetically adsorbed and is made of a metal material that can be magnetically adsorbed, such as iron) is slidably arranged in the inner cavity of the storage groove. An elastic member 321 (spring) is arranged between the storage groove and the pushing member 322. An emission port is formed on the right side wall of the screening box 301. The emission port is flush with the filter screen 302. A cover plate 312 is hinged to the top of the inner cavity of the emission port. When the feeding member 206 is activated to introduce the objects inside the storage box 202 into the screening box 301, the first driving member 320 works to move the nut sleeve to the left, pushing the magnetic block 319 to move into the inner cavity of the storage groove inside the slot, for adsorbing the pushing member 322 to move it upward to form a gap between the pushing member 322 and the top of the filter screen 302. The nut sleeve continues to move leftward, making the magnetic block 319 drive the slider 318 and the moving plate 310 to move leftward to level and disperse the objects introduced above the filter screen 302, facilitating the screening of seeds. Before the feeding member 206 is activated (that is, before the objects inside the storage box 202 are introduced into the screening box 301), the first driving member 320 works to move the nut sleeve to the right, making the magnetic block 319 move rightward out of the inner cavity of the storage groove, so that the magnetic force received by the pushing member 322 disappears. Under the action of the elastic member 321, the bottom of the pushing member 322 contacts the top of the filter screen 302. As the nut sleeve continues to move rightward, the magnetic block 319 pulls the slider 318 and the moving plate 310 to move rightward, making the pushing member 322 move rightward to push the impurities remaining above the filter screen 302 to the right. When the impurities directly contact the cover plate 312, it is used to push the cover plate 312 to rotate to open the emission port, so that the impurities above the filter screen 302 are discharged from the emission port.

[0025] In this embodiment, as a further optimized solution, please refer to Figure 4 . A guiding plate 314 is arranged on the top wall of the flow guiding cover 313. The impurities discharged from the emission port will fall onto the top of the flow guiding cover 313 and are guided by the guiding plate 314 to be discharged from the left and right sides in the advancing direction of the mobile device 1.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
