Abstract

The present invention discloses a rotary squirrel cage type mechanism for orderly distributing rice seedlings. The present invention comprises a bowl seedling full disk conveying device, a feeding device, a bowl seedling liftout device and a driving device. A drive sprocket drives a seedling disk on a conveying belt to be wound to a squirrel cage driven by the drive sprocket so that the seedling disk and the squirrel cage can rotate together; both ends of the squirrel cage are orderly fixed to a flange along circumference by screws; a push rod rotates together with the seedling disk wound on the rotating squirrel cage; the speed of a conveying drum is higher than that of the rotating squirrel cage; the conveying belt accurately pushes the seedling disk to be wound on the squirrel cage. 16 cams fixedly arranged on a cylinder are divided into two groups and are driven by the drive sprocket to rotate at a uniform speed; the 8 cams in each group orderly push a corresponding lever so as to push out a paddy rice bowl seedling in a bowl in the same row with the seedling disk wound on the rotating squirrel cage, so the paddy rice bowl seedling falls into a field, and the ordered rice seedling distribution is completed. The present invention utilizes the differential speed rotation of the cams and the drum and the amplifying action of a lever mechanism, the speed of the push rod for pushing out the bowl seedling is greatly improved, and the consistency of the pushed out bowl seedlings in the same row and the uniformity of planting distance are ensured.

Description

Squirrel cage rotation type ordered rice seedling distribution mechanism
Technical field
The present invention relates to transplanting machine, especially relate to a kind of squirrel cage rotation type ordered rice seedling distribution mechanism.
Background technology
At present, the motor-driven seedling thrower of the paddy rice of selling on the market at home divides and unorderedly loses seedling and lose seedling in order.Unordered to lose the seedling operation simple, but the uniformity of rice shoot in the field be difficult to guarantee that particular needs the peasant again with manually putting again, also brings a lot of inconvenience to later stage field management and results, and owing to problems such as ventilation cause disease.Lose seedling in order and can overcome unordered disadvantage of losing seedling, but realize relatively difficulty, will guarantee that particularly spacing in the rows equates to have very big difficulty; At present domestic also do not have product to come into the market, and external product is too complicated.
Summary of the invention
The purpose of this invention is to provide a kind of squirrel cage rotation type ordered rice seedling distribution mechanism, make ejecting of rice shoot have uniformity, can guarantee that line-spacing equates, can guarantee that again spacing in the rows is even, and simple in structure, reliable operation.
