Description

Technical Field

[0001] This utility model relates to the field of corn seed production technology, and more specifically, to a precision seeding device for corn seed production. Background Technology

[0002] Precision seed sowing for maize is a sowing method developed from spot sowing. It aims to achieve uniform sowing by precisely controlling the position and depth of each seed. Precision seeding ensures that each seed is accurately sown into the soil at a specific distance and depth, thus obtaining uniform germination conditions, promoting the germination of each seed, and ultimately achieving the goal of uniform, full, and robust seedlings.

[0003] Patent authorization number CN222382112U discloses a precision seeding device for corn seed production, including a machine casing. A retaining ring is fixedly connected to the inner side of the machine casing. A feeding plate is integrally formed on the inner top wall of the retaining ring. A storage compartment integrally formed with the machine casing is provided on one side of the feeding plate. A discharge port is opened at the root of the storage compartment. A rotating disk is installed on the inner side of the retaining ring. Seed grooves are opened on the edge of the rotating disk, and multiple seed grooves are arranged radially on the rotating disk. A geared motor is installed on the outer side of the machine casing. The power output end of the geared motor is connected to a transmission shaft extending to the inner side of the machine casing through a coupling. It realizes precision seeding of corn seeds, improves the efficiency of the sowing process, and reduces the labor intensity of manual labor.

[0004] However, according to patent authorization number CN222382112U, the corn seeds entering the hopper are prone to clogging during the feeding process. When clogging occurs, it is necessary to manually clear the blockage, which affects the efficiency of precision sowing. Therefore, we propose a precision sowing device for corn seed production to solve the above-mentioned problems. Utility Model Content

[0022] 3. Beneficial effects

[0023] Compared with existing technologies, the advantages of this utility model are:

[0024] By adding the corn seeds requiring precise sowing into the hopper, simultaneously starting the stepper motor and setting a suitable angular velocity, the power output of the stepper motor drives the transmission shaft to drive the impeller to rotate synchronously. At the same time, the transmission shaft drives the active bevel gear located inside the protective cover to rotate. The active bevel gear and the driven bevel gear combine to drive the shaft to rotate, thereby using the spiral blades set at the top of the shaft to convey the corn seeds in the hopper downwards. Under the action of the guide platform, the seeds are conveyed to the feeding pipe that can only accommodate a single seed. Through the compression between the seeds, the single seeds are conveyed into the inner cavity of the machine box, and the single seeds are output through the outlet by the oscillation of the impeller. This not only achieves precise sowing, but also prevents seed blockage. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Example:

[0034] Please see Figure 1-5A precision seeding device for corn seed production includes a housing 1, a cover 2 bolted to the port of the housing 1, and a stepper motor 3 mounted on the back of the housing 1. A drive shaft 4 connected to the power output end of the stepper motor 3 is installed inside the housing 1. An impeller 5 connected to the drive shaft 4 is also installed inside the housing 1. A discharge port 6 is opened at the bottom of the housing 1.

[0035] A protective cover 7 is installed in the center of the front of the cover 2, and an active bevel gear 8 that is connected to the end of the drive shaft 4 is installed on the inner side of the protective cover 7.

[0036] Above the protective cover 7 is a conveying cylinder 11 with a closed bottom structure. The bottom of the inner cavity of the conveying cylinder 11 is fixedly connected to a guide platform 14. The root of the side wall of the conveying cylinder 11 is connected to a feeding pipe 12 that passes through the machine cover 2. The top of the conveying cylinder 11 is fixedly connected to a hopper 15.

[0037] The top of the protective cover 7 is rotatably connected to a shaft 9 that passes through the conveyor cylinder 11 and extends to the bottom of the hopper 15 via a dustproof bearing. The bottom end of the shaft 9 is connected to a driven bevel gear 10 that meshes with the driving bevel gear 8. The top of the shaft 9 is welded with a spiral blade 13.

[0038] It should be noted that when using this precision seeding device for corn seed production, the corn seeds to be precision-seeded are added to the hopper 15, and the stepper motor 3 is started and a suitable angular velocity is set. The power output end of the stepper motor 3 drives the transmission shaft 4 to drive the impeller 5 to rotate synchronously. At the same time, the transmission shaft 4 drives the active bevel gear 8 located inside the protective cover 7 to rotate. The active bevel gear 8 and the driven bevel gear 10 are combined to drive the shaft 9 to rotate. The spiral blades 13 set at the top of the shaft 9 convey the corn seeds in the hopper 15 downwards. Under the action of the guide table 14, the seeds are conveyed to the feeding pipe 12, which can only accommodate a single seed. The single seed is conveyed into the inner cavity of the machine box 1 by the compression between the seeds, and the single seed is output through the outlet 6 by the swing of the impeller 5. This not only achieves precision seeding, but also prevents seed blockage.

[0039] like Figure 5 As shown, the drive shaft 4 passes through the back of the housing 1, and the through end of the drive shaft 4 is connected to the power output end of the stepper motor 3 through a coupling.

[0040] A rolling bearing is installed at the junction of the drive shaft 4 and the housing 1;

[0041] The drive shaft 4 has an integrally formed key, and the impeller 5 has a keyway in the middle that engages with the key.

[0042] It should be noted that the drive shaft 4 can drive the impeller 5 to rotate normally during the rotation process.

[0043] like Figure 3 , Figure 4 As shown, a connecting shaft that penetrates the cover 2 is welded onto the drive bevel gear 8, and the connecting shaft is connected to the transmission shaft 4 via a coupling;

[0044] A rolling bearing is installed at the junction of the connecting shaft and the cover 2;

[0045] A rolling bearing is installed at the bottom end of the conveyor cylinder 11 where it connects with the shaft 9;

[0046] It should be noted that this reduces the resistance between the driving bevel gear 8 and the shaft 9 during rotation and ensures the meshing accuracy between the driving bevel gear 8 and the driven bevel gear 10.

[0047] like Figure 4 As shown, the outer diameter of the spiral blade 13 is matched with the inner diameter of the conveyor cylinder 11;

[0048] It should be noted that this ensures the seeds are transported downwards normally within the conveyor cylinder 11.

[0049] like Figure 4 As shown, the root of the guide platform 14 extends to the top port of the feeding pipe 12.

[0050] It should be noted that it has a good guiding effect on the entry of a single seed into the feeding tube 12.

[0051] In use: Add the corn seeds that need to be precisely sown into the hopper 15, start the stepper motor 3 and set an appropriate angular velocity. The power output end of the stepper motor 3 drives the transmission shaft 4 to drive the impeller 5 to rotate synchronously. At the same time, the transmission shaft 4 drives the active bevel gear 8 located inside the protective cover 7 to rotate. The active bevel gear 8 and the driven bevel gear 10 are combined to drive the shaft 9 to rotate. The spiral blades 13 set at the top of the shaft 9 convey the corn seeds in the hopper 15 downwards. Under the action of the guide table 14, the seeds are conveyed to the feeding pipe 12, which can only accommodate a single seed. The single seed is conveyed into the inner cavity of the machine box 1 by the compression between the seeds. The single seed is output through the outlet 6 by the swing of the impeller 5.

[0052] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
