Agricultural machine seeding control device

Abstract

The invention discloses an agricultural machine seeding control device, which comprises a seeding box (2) arranged on a rack (1) and a seed metering motor (4) arranged at one end of the seeding box (2), and is characterized in that a GPS (Global Positioning System) controller (3) interlocked with the seed metering motor (4) is arranged on one side of the seeding box (2), a seed metering shaft (5) on the seed metering motor (4) is connected with a transition wheel (6) through a transmission chain, and the transition wheel (6) is connected with a transmission wheel (7) of a seed metering box (8) through a transmission chain. After an operation agricultural machine is accurately positioned through a GPS, the advancing speed of the agricultural machine is determined, and the rotating speed of the seed metering wheel and the advancing speed of the agricultural machine are interlocked, so that the seeding quantity in the advancing process is stably controlled; meanwhile, the seed supply speed of a seed metering pipe to the seed metering wheel is controlled so as to control the transverse seeding quantity of the seeds; and the seed metering wheel with low rotating speed and large diameter is adopted, so that a better seeding control effect can be achieved.

Description

technical field [0001] The invention relates to a control machine, in particular to an agricultural machinery sowing control device, which belongs to the technical field of agricultural machinery sowing equipment. Background technique [0002] In the early days, when farmers sowed seeds, they used the method of walking from one end of the field to the other, throwing handfuls of seeds on the ground while walking, but this method called "scattering" is very unreliable, and some places will Many seeds fall, while few seeds fall in other places, so people gradually develop mechanical farm tools to replace manual sowing. For this reason, agricultural machinery for sowing is a planting machine that uses crop seeds as the object of sowing. [0003] However, all existing similar equipment for sowing agricultural machinery generally do not have a precise positioning function, and the operating speed of the agricultural machinery and the rotation speed of the seeding wheel of the see...

AI Technical Summary

Problems solved by technology

[0003] However, among all the similar equipment of the existing agricultural machinery for sowing, they generally do not have the precise positioning function, and the speed of the agricultural machinery operation and the rotation speed of the seeding wheel of the seeding mechanism generally cannot be relatively uniform, and the continuous and stable control of the seeding amount cannot be guaranteed.
