Abstract
The utility model relates to a speed change gear, in particular to a coaxial transmission for a corn planter. The utility model solves the problems that a chain speed change structure of a planter is cumbersome, and a chain is easily broken or easily falls off. The coaxial transmission comprises a speed change disk, a gear I, a gear II, a gear III, a gear IV, a driving shaft and a driven shaft; one side of the speed change disk is provided with the gear I and the gear II which are meshed; the gear I is provided with the gear IV which rotates with the gear I non-coaxially; one side of the gear II is provided with the gear III which rotates with the gear II coaxially; the gear III is meshed with the gear IV; the driving shaft is connected with the gear I; the driven shaft is connected with the gear IV; and the driven shaft is sleeved in the driving shaft. According to the coaxial transmission, gears replace chains for speed change, and a speed change structure between a land wheel and a seeding apparatus of the traditional planter is simplified.
Description
Technical field
The utility model relates to speed change gear, particularly a kind of coaxial speed variator of corn planter.
Background technique
Corn is one of the grain crops the most widely that distribute in the world, and corn is very large at the cultivated area of China, distributes also very wide, is one of main food of north of China and Southwest Mountainous Areas and other winterbourne area people.
Typically use chain between the seeding apparatus of corn planter and land wheel and be connected, carry out speed change by adjusting the gear size that is connected with chain.When land wheel rotates, be connected chain with land wheel and drive seeding apparatus work by a series of transmission, thereby sowing machine is sowed in the process of advancing.The chain speed changing structure of tradition sowing machine has heavier, and the problem that easily ruptures.
Summary of the invention
The utility model is heavy for the chain speed changing structure that solves sowing machine, the problem that chain easily ruptures and comes off, thus a kind of coaxial speed variator is provided.
In order to address the above problem, the utility model adopts following technological scheme: a kind of coaxial speed variator comprises speed disk, gear I, gear II, gear III, gear IV, driving shaft and driven axle; One side of speed disk is provided with gear I and gear II, gear I and gear II are meshing, the gear I is provided with the gear IV of non-coaxial rotation, gear II one side is provided with the gear III of coaxial rotation, gear III and gear IV are meshing, driving shaft is connected with the gear I, and driven axle is connected with the gear IV, and driven axle is enclosed within driving shaft.
During the utility model work, driving shaft is connected with land wheel, drives driving shaft when land wheel rotates and rotates, and driving shaft drives the gear I that is connected with it again and rotates, and the gear I drives with its meshing gear II and rotates; The gear II drives with its coaxial gear III and rotates, and drives when the gear III is rotated with its meshing gear IV to rotate, and the driven axle that is connected with the gear IV rotates under the drive of gear IV.Because 4 gears are not of uniform size, thereby make the driving shaft effects that reach speed change different from the rotating speed of driven axle.
The beneficial effects of the utility model are: replace chain to carry out speed change with gear, simplified the speed changing structure between traditional seeder ground wheel and seeding apparatus, the problem that has solved easy chain breakage and come off.
