[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] Please see Figure 1 A portable alpine meadow wild plant seed collection and sowing device includes: a mobile device 1, which refers to a mobile vehicle (such as a mobile cart), and also includes: a seed collection component 2, a screening component 3 and a sowing component 5;

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 The seed collection assembly 2 includes an air intake hood 204, a conduit 203, a storage box 202, and an air extraction device 201 connected in sequence. The air extraction device 201 includes a housing, fan blades installed inside the housing, and a motor for driving the fan blades to rotate. A brush roller 205 is rotatably installed in the inner cavity of the air intake hood 204. A drive device (motor) is installed on the side wall of the air intake hood 204. The output shaft of the drive device is connected to the shaft of the brush roller 205 to drive the brush roller 205 to rotate.

[0034] It should be noted that the air inlet of the suction device 201 is connected to the storage box 202 through the air inlet pipe. The inside of the air inlet pipe is equipped with a filter screen to prevent the sucked-up objects from remaining in the inner cavity of the storage box 202.

[0035] Please see Figure 2 and Figure 4 The screening component 3 includes a screening box 301, a filter screen 302 disposed inside the screening box 301, and an air separation component located below the filter screen 302. The air separation component includes an air inlet box 303, an air pump 304, a flow sensor 315 (gas flow sensor), and a controller 305 (such as a PLC controller). The screening box 301 is installed on the top wall of the mobile device 1, and an air inlet is provided on the left side wall of the screening box 301. The air inlet box 303 is installed on the left side wall of the screening box 301, and the air inlet and air inlet box 304 are connected. 3. The air pump 304 is installed on the top wall of the mobile device 1. The air outlet of the air pump 304 is connected to the air inlet box 303. The flow sensor 315 is installed in the inner cavity of the air inlet. The air inlet box 303 is connected to the exhaust port of the air extraction device 201 through a pipe. The inner cavity of the screening box 301 is equipped with a vibration motor 306, which is used to vibrate the filter screen 302. The right side wall of the screening box 301 is provided with an impurity outlet 316 and a seed outlet 317 from top to bottom. The seed outlet 317 is connected to the storage box 4.

[0036] Please see Figure 4 and Figure 5The top of the screening box 301 has an inlet, which connects the screening box 301 to the storage box 202. The screening box 301 has a feeding component 206, which includes an electric telescopic rod and a sealing plate installed on the moving end of the electric telescopic rod. The sealing plate blocks the inlet, and the electric telescopic rod moves the sealing plate to open or close the inlet.

[0037] Please see Figure 1 , Figure 2 and Figure 8 The seeding assembly 5 includes a feed box 501, several feeding pipes 502 connected to the bottom of the feed box 501, several material plates 503 disposed in the inner cavity of the feed box 501, and several second driving components 504 (electric telescopic rods). The moving end of the second driving component 504 is connected to the material plate 503. The number of material plates 503 corresponds one-to-one with the number of feeding pipes 502. The feed box 501 is installed on the bottom wall of the mobile device 1. The top wall of the feed box 501 has a feed inlet, which is connected to the discharge port of the storage box 4 (the storage box 4 is equipped with a baffle plate and an electric telescopic rod for driving the baffle plate to move. The baffle plate blocks the discharge port, and the electric telescopic rod moves the baffle plate to control the opening and closing of the discharge port). The several feeding pipes 502 are arranged sequentially along the direction perpendicular to the movement of the mobile device 1.

[0038] Working principle:

[0039] Seed collection: Point the air intake hood 204 toward the ground near the wild plants, and then start the air extraction device 201 to create a negative pressure at the inlet of the air intake hood 204, which is used to suck the seeds on the ground into the inner cavity of the air intake hood 204, and then enter the inner cavity of the collection box 202 through the conduit 203. During the seed collection process, the driving device drives the brush roller 205 to rotate and sweep the ground to move the seeds on the ground, so that the air intake hood 204 can adsorb them.

[0040] Seed screening: After a period of time, the feeding component 206 operates, connecting the collection box 202 and the screening box 301, allowing the objects collected inside the collection box 202 to enter the screening box 301 and fall onto the filter screen 302. Then, the feeding component 206 controls the separation of the collection box 202 and the screening box 301. The vibration motor 306 operates, causing the filter screen 302 to vibrate, shaking off objects smaller than the aperture of the filter screen 302 (including seeds), filtering out large impurities such as branches, leaves, and soil (which remain above the filter screen 302). The gas discharged by the exhaust device 201 enters the inner cavity of the air inlet box 303 through a pipe and enters the screening box through the air inlet. The air inlet box 301 blows air onto the seeds passing through the filter screen 302, performing air separation (removing light impurities such as empty shells and dust). The resulting impurities are discharged from the impurity outlet 316, while the air-separated seeds 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 onto the seeds for air separation, the flow sensor 315 is used to detect the air flow rate. When the air flow rate is lower than the threshold, the controller 305 controls the air pump 304 to start, replenishing air into the air inlet box 303 to increase the air flow rate blown onto the seeds (the increased airflow is precisely controlled according to the air flow rate detected by the flow sensor 315).

[0041] Sowing: The seeds inside the storage box 4 enter the inner cavity of the material box 501. The second driving component 504 drives the material plate 503 to move, releasing the blockage of the discharge pipe 502, so that the seeds inside the material box 501 fall onto the ground of the sowing area through the discharge pipe 502. At the same time, the mobile device 1 moves, so that the seeds continue to fall into the sowing area.

[0042] It should be noted that, in order to improve the survival rate after sowing, soil turning equipment and fertilization and watering equipment are installed on the feed box 501. Before sowing, the soil in the sowing area is turned over, and the land after sowing is fertilized and watered. The processes of turning over the soil, fertilizing and watering are all existing technologies and will not be described in detail here.

[0043] It should also be noted that the seeds collected in this application refer to seeds that have fallen to the ground, such as sedges and Kentucky bluegrass.

[0044] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 4The bottom of the inner cavity of the screening box 301 is provided with a second guide block 309. The top wall of the second guide block 309 is inclined. Seeds after air separation 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 can be discharged from the seed outlet 317. The inner walls of the left and right sides of the screening box 301 are provided with first guide blocks 307. 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. Seeds that pass through the filter screen fall onto the inclined surface at the top of the first guide block 307, which guides the seeds and makes them concentrate near the air inlet, ensuring that the air inlet blows the downward seeds better and increases the effect of air separation.

[0045] In this embodiment, as a further optimization, 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 inclined downward, and the right end of the guide plate 308 is inclined downward. The right end of the guide plate 308 is flush with the impurity outlet 316. A flow guide hood 313 is provided on the right side wall of the screening box 301. The flow guide hood 313 covers the impurity outlet 316. Openings are provided on both sides of the flow guide hood 313. The two openings are located on the left and right sides of the moving direction of the mobile device 1, respectively. During the air separation process, when some seeds fall to the left side of the guide plate 308, the seeds will not be guided away by the guide plate 308 because the left side of the guide plate 308 is inclined downward. The guide plate 308 can hold the impurities generated by screening and guide the impurities to be discharged from the impurity outlet 316. The flow guide hood 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.

[0046] In this embodiment, as a further optimization, please refer to... Figure 4 , Figure 5 , Figure 6 and Figure 7A sliding groove 311 (horizontally arranged) is provided on the inner wall of the screening box 301. A slider 318 is slidably arranged in the inner cavity of the sliding groove 311. A movable plate 310 is provided on the slider 318. The movable plate 310 is located directly above the filter screen 302. A first driving component 320 is installed on the screening box 301. The first driving component 320 includes a threaded sleeve slidably arranged in the inner cavity of the sliding groove 311, a screw screwed into the threaded sleeve, and a motor for driving the screw to rotate. A slot is provided on the right side wall of the slider 318. A magnetic block 319 is slidably arranged in the inner cavity of the slot (the magnetic block 319 can be opened in the slot). The moving plate 310 moves left and right, but the magnetic block 319 does not separate from the slot. The screw sleeve is connected to the right side wall of the magnetic block 319. A storage slot is provided at the bottom of the moving plate 310. A pusher 322 (such as a push plate, which can be magnetically attracted and is made of a magnetically attracted metal material, such as iron) is slidably provided in the inner cavity of the storage slot. An elastic element 321 (spring) is provided between the storage slot and the pusher 322. A discharge port is provided on the right side wall of the screening box 301. The discharge port is flush with the filter screen 302. A cover plate 312 is hinged to the top of the inner cavity of the discharge port. When the unloading part 206 is activated, the contents of the storage box 202 are discharged. When the object is introduced into the screening box 301, the first driving component 320 operates, causing the screw sleeve to move to the left, pushing the magnetic block 319 into the inner cavity of the receiving groove. This magnetic block is used to attract the pusher 322, causing it to move upward and create a gap between it and the top of the filter screen 302. The screw sleeve continues to move to the left, causing the magnetic block 319, along with the slider 318 and the moving plate 310, to move to the left, spreading and dispersing the object introduced into the receiving box 202 above the filter screen 302, facilitating seed screening. Before the unloading component 206 is activated (i.e., before the object inside the receiving box 202 is introduced into the screening box 301), the object is removed from the receiving box 202. When the first driving member 320 operates, it moves the screw sleeve to the right, causing the magnetic block 319 to move to the right and move out of the inside of the receiving groove. This causes the magnetic force on the pusher 322 to disappear. Under the action of the elastic member 321, the bottom of the pusher 322 contacts the top of the filter screen 302. As the screw sleeve continues to move to the right, the magnetic block 319 pulls the slider 318 and the moving plate 310 to the right, causing the pusher 322 to move to the right and push the impurities remaining on the filter screen 302 to the right. The impurities directly contact the cover plate 312, which pushes the cover plate 312 to rotate, opening the discharge port and allowing the impurities on the filter screen 302 to be discharged from the discharge port.

[0047] In this embodiment, as a further optimization, please refer to... Figure 4 The top wall of the flow deflector 313 is provided with a guide plate 314. Impurities discharged from the discharge port will fall onto the top of the flow deflector 313 and be guided by the guide plate 314 to be discharged from the left and right sides of the moving device 1 in the forward direction.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
