Abstract
The utility model discloses a roller connecting lever seed metering device, which relates to a precision seed metering mechanism for dialing plate type dibbler in the agricultural seeding tool. A roller 3 is connected at the front end of a right-angle connecting lever 4. A crankshaft 6 at the rear part of connecting lever 4 is inserted into a single seed metering assembly 1 to be fixed, and the front part of connecting lever 4 is connected with a single seed metering assembly 1 through a restoring spring 2. The roller connected at front end of connecting lever can rotate matched with the mixing teeth salience during the mixing teeth of connecting lever is continuously pulled up, and plays the function as that similar to a bearing. The utility model has the advantages that the structure is simple, the operation is smooth, the wearing is reduced, and the precision seed metering effect can still achieved even in long term operation.
Description
One, technical field
The dial-type dibbler essence that the utility model relates in a kind of agricultural seeder facility is measured kind of a mechanism, especially roller connecting lever seed taking device.
Two, technical background
Seeder is widely used in the prior art, wherein a kind of dibbler commonly used mainly comprises columnar Artenkreis, plant a plurality of seed-taking device assemblies fixing on the ring outer wall, all connect a connecting lever on each seed-taking device assembly, the letter mill handle bent axle of this connecting lever end standing shape, when the connecting lever end when the connecting lever teeth that rotates is stirred continuously, drive the work of single seed-taking device assembly and get kind, actual operating position shows that because connecting lever and teeth cooperating are the sliding friction mode, resistance is big in the work, wearing and tearing are big, after using a period of time, the respective outer side edges gap is strengthened, and causes and gets kind of mechanism's job insecurity, and fault rate constantly increases, can not guarantee that essence measures kind, the mechanical wear influence is normal to be used, and increases maintenance cost, simultaneously, the seed number of at every turn sowing can not accurately be controlled, and causes the waste to seed.
Three, summary of the invention
Goal of the invention of the present utility model is, proposes that a kind of can to improve machine work smooth and easy, reduces wear, keep stable accurately get kind get kind of a structure, i.e. roller connecting lever seed taking device.
Goal of the invention of the present utility model realizes that by following measure rectangular-shaped connecting lever front end connects roller.
Connecting lever front end in the utility model connects roller, can cooperate rotation with the teeth projection when the connecting lever teeth is stirred continuously, plays the effect of similar bearing.Structure is simple and clear, and it is smooth and easy to work, reduce wear, and working stability, the realization long-term work still can essence be measured kind of an effect.

Five, embodiment
Embodiment 1: rectangular-shaped connecting lever 4 front ends connect roller 3.Connecting lever 4 rear crankshaft 6 are inserted single getting in kind of the assembly 1 and are fixed.Connecting lever 4 front portions are connected with single kind of the assembly 1 of getting by back-moving spring 2.
5 on parallel two supports that stretch out of connecting lever 4 front ends are by axis of a cylinder 7 fixedly connected rollers 3, and it is spool parallel that this axis of a cylinder 7 and connecting lever 4 rear crankshaft 6 are.
During sowing, when connecting lever teeth 8 rotates, lobe 9 on its outer rim is stirred 3 rotations of connecting lever 4 front end rollers and is promoted connecting lever 4 drive connecting levers 4 rear crankshaft 6 rotation generation torsion simultaneously, thereby driving corresponding single kind of the assembly 1 of getting finishes and gets kind, after lobe 9 was dialled connecting lever 4 front end rollers 3, connecting lever 4 resetted under back-moving spring 2 drives.
