Embodiment Construction
[0012] Such as figure 1 , figure 2 with image 3 As shown, a double-row misplaced convex spoon convex step precision seed metering device is composed of a housing 1, a seed injection tube 4, a seed metering wheel 7, a seed retaining plate 12, a seed picker 14, an inoculation cup 15, a seed metering Shaft 6 and bearing 5 are formed.
[0013] The housing 1 is connected by said bolts II13.
[0014] The seed injection pipe 4 is arranged on one side of the housing 1 , the seed injection pipe 4 is connected to the housing 1 , and the seeds enter the seed wheel 7 through the seed injection pipe 4 .
[0015] The seeding wheel 7 is arranged inside the housing 1, connected with the housing 1 through the seeding shaft 6, fixed by the bolt I11, the flat washer 9 and the spring washer 10, and shares the seed metering cover with the housing 1; Seed wheel 7 is a semi-closed cavity.
[0016] The seed blocking plate 12 is arranged on the seed meter cover and fixed by the screws 8 .

The invention provides a double-row misaligned convex-spoon convex-step precision seed sowing device. The device is composed of a shell, a seed inlet tube, a seed discharging wheel, seed metering devices, seed receiving cups, a seed retaining plate, a seed discharging shaft and a bearing, and is characterized in that the lower end of the shell is provided with a seed discharging port, the seed inlet tube is arranged on the shell and is communicated with the shell, the seed discharging wheel is connected with the shell through the seed discharging shaft, the seed retaining plate is arranged on a seed sowing device cover, and the seed metering devices and the seed receiving cups are arranged on the inner wall of the seed discharging wheel and are in uniformly and alternately misaligned distribution in two rows. The double-row misaligned convex-spoon convex-step precision seed sowing device has the advantages that through the uniformly and alternately misaligned distribution of the seed metering devices and seed receiving cups in two rows, in the case of high-speed operation of a seeder, the number of the seed metering devices is increased, and the rotation speed of the seed discharging shaft is reduced; by designing a guiding groove, convex spoons and convex steps, seeds are in line orderly and quantitatively separated, seed metering, seed cleaning and single seed discharging are achieved, and high-speed precision seeding is accordingly achieved.
Description
technical field [0001] The invention relates to a seed metering device for a planter, in particular to a precision seed metering device with double rows of dislocated convex spoons and convex steps. Background technique [0002] The seed meter is one of the core components of the precision seeder. At present, there are mainly two types of single-grain precision metering devices: air suction type and mechanical type. The air-suction precision seed metering device has high seeding accuracy and good versatility, but it has high requirements on the sealing of the air chamber, the structure is more complicated, and it is easy to wear; the mechanical seed metering device such as the eye wheel and the horizontal disc mainly rely on Gravity or seed pushers are used for seeding, although the structure is simple and easy to maintain, but it has poor adaptability to high-speed seed filling and it is difficult to control the seeding accuracy during the working process. The rotation sp...
