Problems solved by technology

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 pusher 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

Embodiment Construction

[0011] Such as figure 1 , figure 2 and image 3 As shown, a double fixed seed metering device is composed of a housing 1, a seeding wheel 5, a seed picker 7, an inoculation cup 8, a seeding shaft 6 and a seeding tube 4.

[0012] 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 5 through the seed injection pipe 4 .

[0013] The seed metering wheel 5 is arranged inside the housing 1, connected with the housing 1 through the seed metering shaft 6, and shares the seed metering device cover with the housing 1; the seed metering wheel 5 is a semi-closed cavity.

[0014] The seed picker 7 is arranged on the inner wall of the circumference of the seed wheel 5, and when it turns over the seed cluster, the two side plates of the seed picker 7 guide the seeds into the guide groove; The stress changes, and the redundant seeds slide down due to their own gravity, and the see...

Abstract

The invention provides a double-seed-fixation precise seed metering device. The double-seed-fixation precise seed metering device is composed of a shell, a seed metering wheel, seed taking devices, seed collecting cups, a seed metering shaft and a seed inlet pipe, and is characterized in that the seed metering wheel and the seed metering shaft are connected with each other, the seed taking devicesand the seed collecting cups are arranged on the inner wall of the seed metering wheel and evenly and alternately distributed, the seed input pipe is arranged on the shell and communicated with the shell, and a seed metering hole is formed in the lower end of the shell. By designing a guide groove and double seed fixation plates, seeds are orderly arrayed and quantitatively separated, the seed taking, seed carrying, seed cleaning and single seed metering are realized, and therefore the seed metering precision is improved.

Description

technical field [0001] The invention relates to a seed metering device for a planter, in particular to a double-fixed and precise seed metering device. 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 process of picking and clearing seeds is the key to affect...
