Abstract
Disclosed is a turn arm elastic reset device for the hole sowing seed taking apparatus, relating to a driver plate type precision seed taking mechanism for the hole sowing apparatus in the agricultural sowing machines. Wherein, a reset spring (4) is connected between a transmission structure connected with a right-angle-shaped turn arm (2) and a shell of the seed taking apparatus (1). The transmission structure connected with the turn arm (2) , under the effect of the reset spring (4), can keep resetting correctly and in time to assure that the next action finish smoothly when the malaxate teeth of the turn arm continually handset and when the malaxate teeth are separated from the turn arm after the malaxate teeth stick up to coordinate with rotating work. The utility model has simple structure, works smoothly, reduces the wear, works stably and can still take the seeds precisely even if the utility model works for a long time.
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 bunch planting seed-taking device connecting lever elasticity reset 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, because connecting lever and teeth cooperating are the sliding friction mode, connecting lever with can not keep accurately and timely resetting after teeth contacts cooperating, resistance is big in the work, wearing and tearing are big, and after use a period of time, the respective outer side edges gap is strengthened, cause and get kind of mechanism's job insecurity, fault rate constantly increases, and can not guarantee that essence measures kind, and the mechanical wear influence is normal to be used, increase 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, propose that a kind of can to improve machine work smooth and easy, reduce wear, can keep kind of the structure of getting that accurately and timely resets after keeping the stable connecting lever of accurately getting kind and teeth contacting cooperating, i.e. bunch planting seed-taking device connecting lever elasticity reset device.
Goal of the invention of the present utility model realizes by following measure, is connected back-moving spring between the drive mechanism that rectangular-shaped connecting lever connected and seed-taking device housing.
The drive mechanism that connecting lever connected in the utility model, can be under action of reset spring, when the connecting lever teeth is stirred continuously when breaking away from after the teeth projection cooperates rotation work, can keep accurately and timely resetting, guarantee that next action finishes smoothly, structure is simple and clear, it is smooth and easy to work, reduce wear, working stability, the realization long-term work still can essence be measured kind of an effect.

Five, embodiment
Embodiment 1: comprise kind of the semicircle wheel 6 of getting by the power transmission shaft connection in the drive mechanism that rectangular-shaped connecting lever 2 is connected, the fixing moving spring abutment 3 in the swing arm middle part of connecting lever 2, on the seed-taking device housing 1 with the swing arm static state of connecting lever 2 near the fixing fixed spring base 5 in position, be connected back-moving spring 4 between moving spring abutment 3 and the fixed spring base 5.
During sowing, when the connecting lever teeth rotated, the lobe on its outer rim was stirred connecting lever 2 front ends and is rotated and promote connecting lever 2 simultaneously and drive the rear crankshaft rotation and produce torsion, finished and got kind thereby drive corresponding single kind of the assembly of getting, after lobe was dialled connecting lever 2 front ends, connecting lever 2 resetted under back-moving spring 4 drives.
The drive mechanism that connecting lever connected among the utility model embodiment, can be under action of reset spring, when the connecting lever teeth is stirred continuously when breaking away from after the teeth projection cooperates rotation work, can keep accurately and timely resetting, guarantee that next action finishes smoothly, structure is simple and clear, it is smooth and easy to work, reduce wear, working stability, the realization long-term work still can essence be measured kind of an effect.
