[0026] As shown in FIG. 4 and FIG. 5, the chain 9 is formed by connecting a plurality of chain plates 901 at their ends with hinges. On one side of the chain plates 901 facing the opposite side of the sprocket, each of the chain plates 901 has a cylindrical first groove 902, and each of the first grooves 902 has a conical drill 903 disposed therein. The conical surfaces of the drills 903 face the openings of the corresponding first grooves 902, and each of the first grooves 902 has a first arc-shaped notch 904 at its openings, so that the soil discharged when the drill is drilled has a sufficient accumulation space. A first through hole 905 is opened on the bottom surface of the first groove 902, a gear post 906 is disposed in the first through hole 905, the lower end of the gear post 906 is fixedly connected to the top surface of the corresponding drill 903, a ring gear 907 is slidably connected to the gear post 906, and the ring gear 906 is rotatably connected to the first through hole 905 via a bearing 908. A first spring 909 is fitted on the gear post 906 and between the drill 903 and the bearing 908, and both ends of the first spring 909 are fixedly connected to the drill and the inner ring of the bearing 908 respectively. When the drill is not subjected to force, the first spring 909 automatically moves into the first groove. A contact block 910 is rotatably connected to the upper end of each of the gear posts 906, and a horizontal rack 10 is fixedly attached to the inner wall of the housing 2 on the side corresponding to the chain plate 901 close to the ground, and each of the gear posts 906 can mesh with the rack 10, that is, when the chain plate 901 moves to one side of the ground and approaches the rack, the corresponding gear post meshes with the rack, and at this time, as the chain plate continues to move, the gear post rotates with the rack, and the corresponding drill also rotates.

[0027] As shown in Figures 1, 3 and 4, a circular belt 11 is arranged inside the housing 2 and near the opening of the housing in the center of the chain 9, and the belt 11 is stretched by four belt pulleys 12, where the belt pulley 12 of the sprocket closest to the traveling direction of the device is rotatably connected to the inner wall of the housing 2, one end of the remaining three belt pulleys 12 are all rotatably connected to electric slide blocks 13, which are all electrically connected to the control system, and the belt pulley 12 of the sprocket closest to the traveling direction of the device is rotatably connected to the inner wall of the housing 2, one end of the remaining three belt pulleys 12 is ... A horizontal first electric guide rail is fixedly attached to the location corresponding to the belt pulley closest to the housing 2, and the corresponding electric slide block 13 is slidably attached to the first electric guide rail 14, the other two belt pulleys 12 are located in the center of the housing 3, and one of the belt pulleys 12 is located directly above the other belt pulley 12, and an identical vertical second electric guide rail 15 is arranged on one side of the two electric slide blocks 13 located in the center of the housing 2, and the corresponding electric slide block 13 is slidably attached to the second electric guide rail 15.As shown in FIG. 1, the electric slide block moves the belt pulley located at the middle lower position to the lowest position of the second electric guide rail, and together with the two belt pulleys close to the sprockets, forms two mutually symmetrical inclined planes below the belt. At this time, the belt is in working condition, and when the chain plate moves below the belt, the contact block at the upper end of the corresponding gear post contacts the belt, causing the belt to rotate due to frictional force. Under the action of the belt inclined plane, with the rotation of the chain, the gear post moves downward, pushing the rotating drill to protrude the first groove, and the drill can further drill a hole in the ground. When the chain plate moves to the center of the belt, the drill is at the deepest position in the ground and continues to move. Then, the gear post slowly moves up according to another slope of the belt, and the drill gradually returns into the first groove. The electric slide block drives the belt pulley located in the middle lower part to move up along the second electric guide rail, and the electric slide block drives the belt pulley located in the middle upper part to move down along the second electric guide rail, and the electric slide block closest to the sprocket drives the corresponding belt pulley to move in the direction of the corresponding sprocket, until the lower part of the belt is stretched horizontally. At this time, the belt is in an inactive state, and the drill on the chain plate is not stretched, so that the device can move normally on the road surface and will not cause any damage to the road surface.

[0028] As shown in Figures 1, 3 and 4, a cylindrical sorting box 16 is fixedly mounted in the center of the inside of the housing 2 and above the belt 11. The end face of the sorting box 16 is fixedly connected to the inner wall of the housing 2. The sorting box 16 and the seed storage chamber are connected through a seed transport pipe 17. The plant seeds in the seed storage chamber can enter the sorting box 16 through the seed transport pipe by gravity. A cylindrical sorting disk 18 is rotatably mounted between the sorting box 16 and the belt 11. The sorting disk 18 is rotatably connected to the inner wall of the housing 2. A second through hole 19 is opened on the side of the sorting box 16 and at the position corresponding to the sorting disk 18. As shown in Figure 3, the upper side of the sorting disk 18 enters the second through hole 19 and is slidably connected to the sorting box, thereby preventing the seeds from spontaneously falling through the second through hole. The side of the sorting disk 18 A number of second grooves 20 are uniformly opened in the circumferential direction of the surface, and the size of the second grooves 20 is larger than the size of the seeds, but two seeds cannot be stored at the same time. When the electric slide block moves the belt pulley located at the top of the center of the housing to the top, the side of the sorting disc 18 contacts the belt 11, and the rotating belt can rotate the sorting disc at this time. At this time, the seeds in the sorting box enter the second grooves, and as the sorting disc rotates, they move out of the sorting box one by one through the second through holes (because the seeds are of different sizes, two or three seeds may be output, that is, the sorting disc may output one to three seeds at the same time, which does not affect the use of this device). Several third grooves 21 are uniformly distributed on the outer surface of the belt. As the sorting disc continues to rotate, the seeds in the second grooves 20 fall into the third grooves of the belt respectively, and move with the rotation of the belt.

[0029] As shown in FIG. 4 and FIG. 6, a passage 911 is opened on the inner axis of the gear post 906 and the drill 903, a conical enlarged opening 912 is opened on the end face of the contact block 910, the enlarged opening 912 communicates with the passage 911, a conical plug 913 is disposed on the drill 903 at a position corresponding to the passage 911, a plurality of guide bars 914 are uniformly distributed on the plug 913 in the circumferential direction of one side corresponding to the drill 903, the guide bars 914 are fixedly connected to the plug 913, a guide groove 915 is opened on the drill 903 at a position corresponding to the guide bars 914, and the guide bars 914 are inserted into the corresponding guide grooves 915 and can slide therewith. The second spring 916 is disposed on the bottom diameter of the guide bar 914 and the corresponding guide groove 915, which is connected to the belt. The second spring pushes the plug through the guide bar to move away from the passage, opening the passage in a natural state. When the chain plate moves until it contacts the ground, the plug also hits the ground, offsetting the action of the second spring and causing the plug to block the passage. When the chain plate moves under the belt, the seeds in the third groove on the belt fall into the corresponding wide opening and enter the passage. After the drill drills a hole in the ground, when the drill moves up, the plug leaves the ground, at which point the plug is opened by the second spring, and the seeds in the passage fall into the hole dug in the ground.

[0030] As shown in FIG. 3, a seeding box is fixedly mounted in the center of the inside of the housing and above the belt, the seeding box and the seed storage chamber are connected through a seed transport pipe, a cylindrical seeding disk is rotatably mounted on the inner wall of the housing and between the seeding box and the belt, a second through hole is opened on the side of the seeding box at a position corresponding to the seeding disk, the upper side of the seeding disk enters the second through hole and is slidably connected to the seeding box, a plurality of second grooves are uniformly opened in the circumferential direction on the side of the seeding disk, and the size of the second grooves is larger than the size of the seeds, but two seeds cannot be stored at the same time, and when the belt pulley located above the center of the housing is at the top end, the side of the seeding disk contacts the belt.

[0031] As shown in FIG. 8, a second hopper 24 with its trumpet mouth facing upward is disposed between the belt pulley 12 located inside the housing and in the traveling direction of the device and the chain plate 901 close to the ground. The second hopper 24 is fixedly connected to the inner wall of the housing 2. A cover plate 25 is disposed at the lower opening of the second hopper 24. The cover plate 25 is hingedly connected to the second hopper 24. A torsion spring is disposed at the connection part. The torsion spring causes the second hopper to close by itself. A trigger lever 26 perpendicular to the bottom surface of the cover plate 25 is fixedly attached. When the belt rotates to move the third groove above the second hopper, the seeds in the third groove fall into the second hopper. When the chain plate passes under the second hopper, the corresponding contact block presses the trigger lever, counteracting the force of the torsion spring, and the cover plate rotates around the hinge connection point to open, allowing the seeds in the second hopper to fall into the wide opening.

[0032] As shown in FIG. 1, a V-shaped scraper 27 is disposed on the outside of the housing 2, at one end away from the moving direction of the device and close to the ground. The scraper is hinged to the housing 2 via a connecting rod 28, a second electric telescopic lever 29 is hinged to the connecting rod 28, and the other end of the second electric telescopic lever 29 is hinged to the housing 2. The second electric telescopic lever 29 is electrically connected to the control system. When the device moves forward, the scraper scrapes the soil on the ground, and the soil falls back to the ground into the corresponding holes to cover the seeds.

An annular groove is opened on the side of the sprocket 8 for the gear post 906 and the contact block 910 to pass through. The gear post 906 and the contact block 910 are connected to the sprocket Avoid interference.

[0034] As described above, when this device is used, the driving mechanism drives the rotating shaft through the transmission assembly to rotate, the rotating shaft rotates the sprocket, and the sprocket rotates the chain, and then the control system controls the movement of the electric slide block to operate the belt, and the chain plate close to the belt drives the belt to rotate through the contact block, and the slope on the belt also pushes the drill through the contact block and the gear post to extend the first groove and move below the ground, and at the same time, under the action of the rack and the gear post, the drill rotates, and the drill can dig a hole for sowing in the ground. At the same time, the seeds in the seed storage chamber also fall into the third groove on the belt through the seed sorting box and the seed sorting disk, and then fall into the hole through the corresponding middle passage between the gear post and the drill, and finally, under the action of the scraper, the soil piled up at the mouth of the hole re-enters the hole and covers the seeds.

[0035] By disposing a hole drilling assembly on each chain plate, the device can open multiple sowing holes in the ground with a uniform matrix while moving, and can sow seeds at the same time. Moreover, by changing the moving speed of the device as necessary, the drilling and sowing speeds can be automatically changed, making the user's operation easier and more convenient. Moreover, the hole drilling assembly drills holes while rotating, making it easier to drill deeper holes in the ground, which is suitable for crops with high sowing depth requirements. At the same time, by disposing a seed sorting assembly inside the housing, the seeds are divided into a certain number of parts and transported to the sowing assembly via the belt, and the sowing assembly throws the seeds into the holes in the ground at the moment the hole drilling is completed. This design not only has high sowing efficiency, but also allows the seeds to be sown evenly on the ground with a certain interval, so that each plant has enough growth space, and the seeds can absorb nutrients in the soil evenly, which allows the seeds to grow better. Meanwhile, the uniform distribution of the seeds is convenient for harvesting after late maturity.
