Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a high-speed precision seed metering device for an intelligent no-till seeder. Background Technology

[0002] A seed metering device is a key component of a seeder. Its main function is to accurately discharge seeds from the seed box and place them into the soil to achieve efficient and precise sowing. The working principle of a seed metering device usually involves a rotating shaft, a seed-discharging wheel, and blades. Through the synergistic action of these components, seeds are evenly sown into the soil according to predetermined row and plant spacing.

[0003] Existing seed metering devices cannot guarantee 100% seed capture during use, which can cause intermittent seed supply in the delivery pipe, resulting in insufficient seed placement in the seed pit, uneven seed distribution in the soil, and affecting crop planting. Summary of the Invention

Detailed Implementation

[0019] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Please see Figures 1-5 According to one embodiment of the present invention, a high-speed precision seed metering device for an intelligent no-till seeder includes a feed trough assembly 1, which includes a feed trough 101, a guide rail 102, a guide rail outlet 103, and an output slot 104. The guide rail 102 is fixedly disposed inside the feed trough 101, and the guide rail outlet 103 is disposed at the end of the guide rail 102. A plurality of linearly arranged output slots 104 are also fixedly disposed on one side of the feed trough 101. A drive disk assembly 2 includes a drive disk 201, mounting holes 202, and a drive shaft 203. A plurality of drive disks 201 are arranged in a linear array in the feed trough 101, and each drive disk 201 has a plurality of mounting holes 202 arranged circumferentially. A drive shaft 203 is also provided in the middle of the drive disk 201, and several drive disks 201 are fixedly connected to each other through the drive shaft 203; the suction assembly 3 includes a suction pipe 301, a suction head 302, a suction cylinder 303 and a pull rod 304. The suction pipe 301 is fixedly installed in the mounting hole 202. One end of the suction pipe 301 is connected to the suction head 302, and the other end of the suction pipe 301 is fixedly connected to the suction cylinder 303. The suction pipe 301, the suction head 302 and the suction cylinder 303 are connected. The pull rod 304 is slidably inserted in the suction cylinder 303. A piston is installed on the pull rod 304 and is slidably inserted in the inner cavity of the suction cylinder 303.

[0021] In practical application, when crop seeds are output through this high-speed precision seed metering device, the feed trough 101 in the seed metering device is used to hold the crop seeds to be output. Several drive discs 201 are arranged in a linear array in the feed trough 101, and all drive discs 201 are fixedly connected to each other via a drive shaft 203. One end of the drive shaft 203 is connected to a power output source, which can be any type of motor, not specifically described here. When the drive shaft 203 drives several drive discs 201 to rotate synchronously, due to the... The drive disc 201 has several mounting holes 202 circumferentially, and a suction pipe 301 is fixedly installed in each mounting hole 202. A suction cylinder 303 is installed at one end of the suction pipe 301. A pull rod 304 is slidably arranged on one side of the suction cylinder 303, and a piston at one end of the suction cylinder 303 is slidably installed in the suction cylinder 303. When the suction cylinder 303 rotates to one side of the guide rail 102, the pull rod 304, which is linked to the guide rail 102, slides towards the center of the drive disc 201 under drive. During the sliding process, the pull rod 304 moves towards the center of the suction cylinder 303. The piston continuously draws external gas into the inner cavity of the suction cylinder 303. Therefore, during the gas flow, a negative pressure vacuum is created at one end of the suction head 302. This allows the suction head 302 to rotate within the material trough 101, utilizing the negative pressure vacuum to extract seeds from the trough. Furthermore, when seeds are adsorbed at one end of the suction head 302, the inner cavity of the suction cylinder 303 remains under negative pressure to prevent seeds from falling during movement. Since the spring between the pull rod 304 and the suction cylinder 303 is stretched at this time, when seeds are adsorbed... When the seed suction head 302 moves with the suction cylinder 303 to the side of the guide rail outlet 103, the pull rod 304 disengages from the side of the guide rail outlet 103. Due to the disappearance of the limiting structure, the pull rod 304 slides away from the center of the drive disk 201 under the action of elastic force. This causes the piston at one end of the pull rod 304 to squeeze the air in the inner cavity of the suction cylinder 303 and spray the seeds adsorbed at one end of the suction head 302 out from one end of the suction head 302, causing the seeds to fall onto the output groove 104, so that the seed metering device can continuously and evenly transport seeds.

[0022] Please see Figure 4 In a preferred embodiment of the present invention, the suction assembly 3 further includes an L-shaped plate 305, a first elastic element 306, and a second elastic element 307. The L-shaped plate 305 is slidably mounted on the pull rod 304, and the L-shaped plate 305 is elastically connected to the suction cylinder 303 through the first elastic element 306. The other end of the L-shaped plate 305 is elastically connected to the pull rod 304 through the second elastic element 307.

[0023] In practical application, the L-shaped plate 305 is elastically slidably mounted on the pull rod 304, and a first elastic element 306 is assembled between the L-shaped plate 305 and the suction cylinder 303, and a second elastic element 307 is assembled between the L-shaped plate 305 and the pull rod 304. When seeds are adsorbed at one end of the suction head 302, the gas intake is restricted on one side of the suction head 302, so the inner cavity of the suction cylinder 303 is under negative pressure. At this time, when the L-shaped plate 305 moves toward the center of the drive disk 201, it needs to be resisted by two sets of springs and the pressure in the inner cavity of the suction cylinder 303. When no seeds are adsorbed on one side of the suction head 302, the pressure in the inner cavity of the suction cylinder 303 remains unchanged, so one end of the L-shaped plate 305 is only subjected to the elastic force of the two sets of springs. Therefore, under the action of the elastic force, the L-shaped plate 305 can continue to move toward the center of the drive disk 201 and abut against the side of the pressure plate 310.

[0024] Please see Figure 3 In a preferred embodiment of the present invention, the suction assembly 3 further includes a push rod 308 and a roller 309. The push rod 308 is fixedly mounted on one end of the L-shaped plate 305, and the roller 309 is rotatably mounted on the end of the push rod 308, and the roller 309 rolls against the guide rail 102.

[0025] In practical application, several drive discs 201 are connected by several push rods 308. The end of each push rod 308 is rotatably equipped with a roller 309. The roller 309 rolls against one end of the guide rail 102, so that when the drive disc 201 drives the push rods 308 to move, the roller 309 rolls against the guide rail 102, reducing the frictional resistance experienced by the push rods 308 during movement.

[0026] Please see Figure 5 In a preferred embodiment of this invention, the suction assembly 3 further includes a pressure plate 310, a linkage rod 311, and a push arm 312. Several linkage rods 311 are slidably mounted on one end of the drive disk 201. One end of each linkage rod 311 is fixedly connected to a pressure plate 310, which movably abuts against one side of the pull rod 304. The other end of each linkage rod 311 is rotatably connected to a push arm 312, one end of which is slidably mounted on the drive disk 201.

[0027] In practical application, the pressing plate 310 is slidably mounted on one end of the drive disk 201. When the suction head 302 is not adsorbed with seeds, the pull rod 304 presses against the pressing plate 310 during the sliding process, so that the pressing plate 310 moves toward the center of the drive disk 201. During this process, the pressing plate 310 can synchronously pull the linkage rod 311 at one end to move. Since the end of the linkage rod 311 is rotatably connected to the push arm 312, and the push arm 312 is limited and slidably mounted on the drive disk 201, when the linkage rod 311 pulls the push arm 312 toward the center of the drive disk 201, the end of the push arm 312 moves closer to the trigger rod 405, so that the trigger rod 405 can control the seeds to be discharged from one side of the seed replenishment bin 401 during the movement, and make the seeds slide along the inclined guide groove 404 into the output groove 104 to replenish the seeds not adsorbed on the suction head 302 on that side.

[0028] Please see Figure 2 and Figure 5 In a preferred embodiment of the present invention, the high-speed precision seed metering device of the intelligent no-till seeder further includes a reseeding component 4. The reseeding component 4 includes a reseeding bin 401, a blocking block 402, a pin 403, an inclined guide groove 404, and a trigger rod 405. Several reseeding bins 401 are fixedly disposed at one end of the feed trough 101. A blocking block 402 is slidably assembled in the reseeding bin 401. The bottom of the blocking block 402 is connected to the pin 403. One end of the inclined guide groove 404 is connected to the reseeding bin 401, and the other end of the inclined guide groove 404 is disposed on one side of the output groove 104. The trigger rod 405 is fixedly and rotatably disposed on one side of the reseeding bin 401, and one end of the trigger rod 405 is movably abutting against the pin 403. The other end of the trigger rod 405 is disposed on one side of the push arm 312.

[0029] In practical application, when the push arm 312 is in the driving state and is attached to the trigger rod 405, the trigger rod 405 is pressed against the inclined guide groove 404 under the pushing action, so that the blocking block 402 and the pin 403 slide against the elastic force under the pushing action. During the movement, the gap between the blocking block 402 and the seed replenishment chamber 401 is opened, so that the seeds stored in the inner cavity of the seed replenishment chamber 401 can fall through the gap onto the inclined guide groove 404 and slide along the inclined guide groove 404 to the surface of the output groove 104, thereby realizing the replenishment of seeds.

[0030] Please see Figure 2 In a preferred embodiment of the present invention, the output slot 104, the drive disk 201 and the inclined guide slot 404 are all disposed in the same horizontal plane.

[0031] In practical application, when the suction head 302 with seeds adsorbed moves to one end of the guide rail outlet 103, the air inside the suction cylinder 303 sprays the seeds toward the bottom of the inclined guide groove 404, so that the seeds fall onto the output groove 104 after contacting the bottom of the inclined guide groove 404. The supplementary seeds discharged from the seed replenishment bin 401 can slide along the inner cavity of the inclined guide groove 404 onto the output groove 104, so that the output seeds are all directionally discharged along the output groove 104.

[0032] The above embodiments of the present invention provide a high-speed precision seed metering device for an intelligent no-till planter. By setting a plurality of rotating drive discs 201 inside the feed trough 101, and setting a plurality of seed-adsorbing components 3 on the drive discs 201, the seed metering device can continuously adsorb seeds while detecting the adsorption status of the seeds. When seeds are detected to have fallen, seeds can be automatically replenished to keep the number of seeds at the output end stable.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
