Description
Technical field
The present invention relates to a kind of rice planters, and in particular to a kind of light simple array rice planter of modified.
Background technique
Currently, well known Rice Planting Machinery is broadly divided into two classes: 1. torn based on manipulator (seedling claw) cut blanket seedling root with
Divide traditional rice transplanter of pocket transplanting；2. the Novel transplanter based on culture pan seedling tep reel ball planting；Wherein, the first rice is planted
It is more mature to plant mechanical technique, high plant efficiency is reached by the plant of engine high-frequency drive, shortcoming is to hurt root, plant
Rice shoot needs tide over longer period of seedling establishment afterwards because tear cut seedling root and rice transplanting enter mud operation needed for power it is big, it is strong to mechanical material
Degree requires height, and mechanism is usually than cumbersome, consumptive material energy consumption is at high cost, it is inconvenient to operate in massif rice region.Second of rice planting machine

Load, and since the two sides of camshaft along its axis direction are distributed with multiple top seedling needles, multiple top seedling needle is all by cam
Axis drives simultaneously, therefore load when cam axle can be made to be dramatically increased.And in actual operation, due to entire
The total output of rice planter derives from turntable, and increasing considerably for the cam axle load will lead to the increase of turntable driving power, energy consumption
Increase, to reduce the service performance of product.2, due to top seedling needle stretching motion stroke be by the diameter difference of camshaft Lai
It determines, to increase the stretching motion stroke of top seedling needle, it is necessary to increase the diameter of whole camshaft, but due to whole camshaft
Length it is longer, increase that its diameter can directly result in the driving load of whole device and quality dramatically increases, so that device table
Reveal heavy, inflexible.3, due to the stretching motion of top seedling needle by the radial dimension of variation that is generated when cam axle and
It obtains, this radial dimension of variable quantity is relatively small in the unit time, so that the stretching motion speed of top seedling needle is slower；Especially
It is in reseting procedure, top seedling needle also needs to make retraction movement by the elastic force of spring, is not directly driven, is caused by camshaft
It is slower to retract speed；The stretching motion speed for pushing up seedling needle is slow, influences the efficiency for broadcasting seedling.
