Description

Technical Field

[0001] This invention relates to the field of seeder technology, specifically to a hole-planting garlic sprouting seeder. Background Technology

[0002] Garlic, as an important economic crop, is significantly affected by its planting process, which greatly impacts its subsequent growth and yield. Traditional manual planting methods are not only extremely inefficient and labor-intensive, but more importantly, operators struggle to precisely control the orientation of each garlic clove during continuous work—ensuring it is planted upright with the bud tip strictly facing upwards. Incorrect planting orientation directly leads to delayed emergence, gaps in rows, and weak seedlings, ultimately severely reducing yield and quality. To replace manual labor, various garlic planting machines have emerged on the market. While they have made some progress in achieving spot planting and improving operational efficiency, they have fundamental shortcomings in addressing the core agronomical requirement of garlic planting—"positive bud planting." Existing machines generally lack effective and reliable control mechanisms for the orientation of garlic cloves during the processes of the seed-grabbing mechanism picking up the cloves from the seed box, transporting them to the planting point via a conveyor, and finally releasing them into the planting furrow. Garlic cloves are prone to uncontrollable rolling, deflection, and posture changes during these stages, resulting in random orientation when they fall into the planting furrow. The positive bud rate is generally low and unstable, far from meeting the requirements for high-quality planting. Therefore, we propose a hole-planting garlic sprouting machine. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a hole-planting garlic sprouting machine, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a hole-planting garlic sprouting machine, comprising a frame, a machine frame fixedly installed on the top of the frame, a plurality of spring drum-type seed metering devices fixedly installed on the top of the machine frame, a plurality of duckbill-type seeding devices arranged inside the frame, an engine fixedly installed on the top of the frame, a gearbox fixedly installed on the side of the top of the frame near the engine, and a drive device arranged inside the frame; The drum-type seed metering device includes a rotating rod and several seed-receiving discs. An inner vortex spring box is fixedly installed at the bottom of the inner wall of each seed-receiving disc. An inner rotating cover is rotatably connected to the top of the inner vortex spring box, and a vortex spring body is disposed inside the inner rotating cover. A vortex spring connecting piece is fixedly installed at the bottom of the inner rotating cover, and one end of the vortex spring connecting piece is fixedly connected to one end of the vortex spring body. A spiral seed-guiding groove is disposed inside each seed-receiving disc for single-seed directional placement. A first hinged lug is fixedly installed on one side of the inner rotating cover, and a seed pusher is rotatably connected inside the first hinged lug. The seed pusher is in conjunction with the spiral seed guide groove. An outer discharge block is fixedly installed on the outside of the seed receiving plate. The outer discharge block is connected to the inside of the seed receiving plate. Seed drum lugs are fixedly installed on the outside of the seed receiving plate and on the corresponding sides of the outer discharge block. The rotating rod is rotatably connected to the top of the frame through a bearing seat. The rotating rod passes through the seed drum lugs and is rotatably connected to them. A seed dispensing blade is fixedly installed on the outside of the rotating rod and on the corresponding side of the outer discharge block. The seed dispensing blade cooperates with the outer discharge block. The circumferential scraping action of the seed dispensing blade forces the garlic seeds away from the outer discharge block, realizing single-seed precision sowing. The duckbill-type seeding device includes a crankshaft and a drop tube. The drop tube is slidably mounted inside the frame via a ring clamp. A second hinge lug is fixedly mounted on one side of the drop tube. A sliding sleeve is slidably connected to the outside of the drop tube. An installation ring block is fixedly mounted on the top of the sliding sleeve. A trigger rod is fixedly mounted on one side of the installation ring block. The bottom end of the trigger rod is slightly higher than the working plane of the duckbill-type clamp. Correspondingly, linkage rods are hinged on both sides of the sliding sleeve. Two duckbill-type clamps are rotatably connected to the bottom of the drop tube. The other end of the linkage rod is rotatably connected to the duckbill-type clamps. Several synchronous connecting rods are rotatably connected inside the crankshaft. There is a predetermined eccentricity between the crankshaft rotation center and the hinge point of the synchronous connecting rod. The synchronous connecting rod is rotatably connected to the second hinge lug. When the crankshaft rotates one revolution, the eccentricity drives the drop tube to complete one lifting stroke. The lower dead point of this stroke triggers the duckbill-type seeding device to perform an opening and closing action.

[0005] Optionally, the drive device includes a central connecting shaft, which is mounted inside the frame via a bearing housing, and ground wheels are fixedly mounted on both sides of the central connecting shaft.

[0006] Optionally, a second sprocket and a third sprocket are fixedly installed at the output end of the gearbox, a first sprocket is fixedly installed on the outer side of the central connecting shaft, and a first chain is drivenly connected to the outer sides of the first sprocket and the second sprocket.

The outer side of the third sprocket and the fifth sprocket is rotatably connected with a second chain. The outer side of the crankshaft is fixedly installed with a sixth sprocket. The outer side of the fifth sprocket and the sixth sprocket is connected to the third chain for transmission.

[0008] Optionally, an eighth sprocket is fixedly installed on the outer side of the crankshaft away from the sixth sprocket, and a seventh sprocket is fixedly installed on the outer side of one end of the rotating rod and above the eighth sprocket. A fourth sprocket is connected to the outer sides of the seventh and eighth sprockets. The entire vehicle is powered by a gasoline engine and drives the various components through a chain drive with a certain transmission ratio.

[0009] Optionally, a connecting hose is fixedly installed at the bottom of the external discharge block. The bottom end of the connecting hose is fixedly connected to the top of the drop pipe for moving the garlic cloves. The inner diameter of the connecting hose and the inner diameter of the drop pipe are both about 1.5cm to prevent the garlic cloves from rolling over during the movement.

[0010] Optionally, a handle is fixedly installed on one side of the top of the frame for the user to operate the device from the rear.

[0011] Optionally, a rotating mounting frame is provided on one side of the vehicle frame, and a soil covering roller is rotatably connected inside the rotating mounting frame to perform the soil covering operation after sowing is completed.

[0012] Optionally, the top of the seed tray is threaded with a sealing cap to prevent the garlic seeds from popping out from above during the feeding process.

[0013] This invention provides a hole-planting garlic sprouting machine, which has the following beneficial effects: 1. This hole-planting garlic sprouting machine combines a drum-type seed metering device and a duckbill-type seeding device, and adopts a linked seeding structure. After starting, it can perform linked movement, feeding, drilling, planting and covering with soil. Moreover, by adopting a multiple seeding structure, it can effectively improve seeding efficiency and make planting faster.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Please see Figures 1 to 10The present invention provides a technical solution: a hole-planting garlic sprouting machine, including a frame 1, a machine frame 21 fixedly installed on the top of the frame 1, a plurality of spring drum seed metering devices 3 fixedly installed on the top of the machine frame 21, a plurality of duckbill seeding devices 4 arranged inside the frame 1, an engine 5 fixedly installed on the top of the frame 1, a gearbox 6 fixedly installed on the side of the top of the frame 1 near the engine 5, and a drive device 7 arranged inside the frame 1. The seed-discharging device 3 includes a rotating rod 31 and several seed-receiving discs 33. A sealing cap is threaded onto the top of each seed-receiving disc 33 to prevent garlic seeds from popping out during feeding. An inner vortex spring box 34 is fixedly installed at the bottom of the inner wall of each seed-receiving disc 33. An inner rotating cover 35 is rotatably connected to the top of the inner vortex spring box 34. A vortex spring body is housed inside the inner rotating cover 35. A vortex spring connecting piece 38 is fixedly installed at the bottom of the inner rotating cover 35, with one end of the connecting piece 38 fixedly connected to one end of the vortex spring body. A spiral seed-guiding groove 39 is provided inside the seed-receiving disc 33 for directional single-seed accommodating. A first hinge lug 36 is fixedly installed on one side of the inner rotating cover 35. The first hinge lug 36 rotates internally... A seed pusher 37 is connected, which cooperates with the spiral seed guide groove 39. An outer discharge block 310 is fixedly installed on the outside of the seed receiving plate 33. The outer discharge block 310 is connected to the inside of the seed receiving plate 33. Seed drum lugs 311 are fixedly installed on the outside of the seed receiving plate 33 and on the corresponding sides of the outer discharge block 310. A rotating rod 31 is rotatably connected to the top of the frame 21 through a bearing seat. The rotating rod 31 passes through the seed drum lugs 311 and is rotatably connected to them. A seed dispensing blade 32 is fixedly installed on the outside of the rotating rod 31 and on the corresponding side of the outer discharge block 310. The seed dispensing blade 32 cooperates with the outer discharge block 310. The circumferential scraping action of the seed dispensing blade 32 forces the garlic seeds away from the outer discharge block 310, realizing single-seed precision sowing. The duckbill-type seeding device 4 includes a crankshaft 41 and a drop tube 43. The drop tube 43 is slidably mounted inside the frame 1 via a ring clamp. A second hinge lug 44 is fixedly mounted on one side of the drop tube 43. A sliding sleeve 45 is slidably connected to the outside of the drop tube 43. An mounting ring block 46 is fixedly mounted on the top of the sliding sleeve 45. A trigger rod 47 is fixedly mounted on one side of the mounting ring block 46. The bottom end of the trigger rod 47 is slightly higher than the working plane of the duckbill-type clamp 49. Correspondingly, linkage rods 48 are hinged to both sides of the sliding sleeve 45. Two duckbill-type clamps 49 are rotatably connected to the bottom of the drop tube 43. The other end of the linkage rod 48 is rotatably connected to the duckbill-type clamps 49. Several synchronous connecting rods 42 are rotatably connected inside the crankshaft 41. There is a predetermined eccentricity between the rotation center of the crankshaft 41 and the hinge point of the synchronous connecting rod 42. The synchronous connecting rod 42 is rotatably connected to the second hinge lug 44. When the crankshaft 41 rotates one revolution, the drop tube is driven to complete one lifting stroke through the eccentricity. The lower dead point of this stroke triggers the duckbill-type seeding device 4 to perform the opening and closing action.

[0019] The drive unit 7 includes a central connecting shaft 71, which is mounted inside the frame 1 via bearing seats. Ground wheels 72 are fixedly mounted on both sides of the central connecting shaft 71. A second sprocket 10 and a third sprocket 12 are fixedly mounted at the output end of the gearbox 6. A first sprocket 9 is fixedly mounted on the outer side of the central connecting shaft 71. A first chain 11 is driven through the outer sides of the first sprocket 9 and the second sprocket 10. A connecting shaft 23 is rotatably connected to the top of the frame 1 via bearing seats. A fifth sprocket 13 and a fifth sprocket 15 are fixedly mounted at the corresponding ends of the outer side of the connecting shaft 23. The outer sides of the three sprockets 12 and 13 are rotatably connected to the second chain 14. The outer end of the crankshaft 41 is fixedly mounted with the sixth sprocket 16. The outer sides of the fifth sprocket 15 and the sixth sprocket 16 are driven by the third chain 17. The outer side of the crankshaft 41 away from the sixth sprocket 16 is fixedly mounted with the eighth sprocket 19. The outer side of the rotating rod 31 and above the eighth sprocket 19 is fixedly mounted with the seventh sprocket 18. The outer sides of the seventh sprocket 18 and the eighth sprocket 19 are driven by the fourth sprocket 20. The entire vehicle is powered by a gasoline engine and drives the various components through a chain drive with a certain transmission ratio.

[0020] The bottom of the outer discharge block 310 is fixedly equipped with a connecting hose 22. The bottom end of the connecting hose 22 is fixedly connected to the top of the drop pipe 43 for moving the garlic cloves. The inner diameter of the connecting hose 22 and the inner diameter of the drop pipe 43 are both about 1.5cm to prevent the garlic cloves from rolling during the movement.

[0021] The frame 1 has a handle 2 fixedly installed on one side of the top, which is used by the user to operate the equipment from the rear. A rotating mounting frame is provided on one side of the frame 1, and a soil covering roller 8 is rotatably connected inside the rotating mounting frame, so as to carry out the soil covering operation after sowing.

[0022] In summary, this hole-planting garlic seed-aligning planter, before planting, places the garlic seeds in the seed tray 33 with the buds facing upwards, using the spiral seed guide groove 39 as a moving track. Then, the seed tray 33 is closed, and the spiral spring body inside the inner spiral spring box 34 drives the inner rotating cover 35 to rotate, thereby driving the seed pusher 37 to rotate. This causes the garlic seeds inside the seed tray 33 to move towards the outer discharge block 310 and be clamped inside the outer discharge block 310. When planting begins, the engine 5 is started, driving the output end of the gearbox 6 to rotate, thus moving the second sprocket... Driven by sprockets 10 and 12, the force is transmitted to the outside. Through the cooperation of sprockets 10, 9, and 11, the central connecting shaft 71 is rotated, thus propelling the equipment body forward. Simultaneously, sprocket 12, driven by 14, drives 13 to rotate. The synchronous rotation of 13, connecting shaft 23, and 15 drives 17 to move, and simultaneously drives sprocket 16 to rotate. Through the rotation of sprocket 19 and 20 on the other side of crankshaft 41, sprocket 18 and rotating rod 31 are driven to rotate. When the cylinder rotates, it drives the seed-discharging paddle 32 to rotate, which in turn pushes the garlic seeds located inside the outer discharge block 310 into the connecting hose 22, and then drops them into the drop tube 43 through the connecting hose 22. At the same time, the crankshaft 41 rotates synchronously, driving the synchronous connecting rod 42 to move. At this time, the synchronous connecting rod 42 drives the second hinge lug 44 and the drop tube 43 to slide up and down inside the frame 1. When the drop tube 43 moves downward and touches the ground, the duckbill-type clamp 49 inserts into the soil, and then the trigger rod 47 immediately touches the soil layer. At this time, the trigger rod 47 and the safety valve... The ring block 46 and the sliding sleeve 45 cannot continue to move downward due to the obstruction of the soil layer. As the falling tube 43 continues to move downward, the two linkage rods 48 are lifted relative to the falling tube 43. Thus, driven by the linkage rods 48, the two duckbill-shaped cloves 49 rotate outward synchronously. At this time, the garlic seed inside the falling tube 43 falls into the soil. Then, as the position of the synchronous connecting rod 42 moves, the duckbill-shaped cloves 49 return to the initial state in the opposite direction. At the same time, the falling tube 43 moves upward to complete the sowing. Then, as the frame 1 continues to move, the soil covering roller 8 moves to the current position and covers the garlic seed with soil.
