Description

The spiral saw is ploughed sower

Technical field:

The utility model belongs to agricultural machinery technological field, is that a kind of spiral saw is ploughed sower.

Background technology:

In technique known, normally used machine rotary tillage sower, its structure is: utilize the tulwar tooth that is fixed with certain-length on the turning cylinder to carry out cultivating of field, its function singleness, can not divide ditch automatically, do not satisfy and plough the requirement that needs branchs ridge, corrugate and envelope ditch after broadcasting, in addition, because that cutter tooth contacts the lifting surface area of soil is big, during farming cutter tooth is produced bigger resistance or bounce, so need the field farming of coupling big power, the especially rigid soil of incompatibility, power consumption is big, farming efficient is low.What next was that the seeding apparatus of this machine adopts is that the rotor-type program request or the gear teeth are alloted structure, the former shortcoming is the easy jam of honeycomb hole, the latter's shortcoming is that accent is broadcast dumb, the weight of sowing is all non-adjustable, and unicity is strong, sows the different types of kind of period of the day from 11 p.m. to 1 a.m, need to change the different gear teeth, troublesome poeration, effort, time-consuming, efficient is low.

Summary of the invention:

The purpose of this utility model provides a kind of ploughing and broadcasts the efficient height, can satisfy branch ridge, corrugate and the requirement of envelope ditch and different types of seed program request, go and broadcast the cultivated sower of one step completed spiral saw.

Realize that the technical scheme that the purpose of this utility model is taked is: this machine is to be made of ploughing rake and seeder equipped on hand steered or four-wheel tractor, its main feature is: the ploughing rake adopts spiral sawtooth rotary tillage structure, be by support, central shaft, powered drive wheel, the spiral sawtooth is ploughed knife assembly and is formed, support is connected the rear portion of equipped machine, central shaft is connected on the support by bearing, which is provided with powered drive wheel, and be set with a plurality of spiral sawtooth and plough knife assembly, seeder is located at the rear side of ploughing rake, be connected with the securing member that is easy to dismantle with employing cantilever shalving between the ploughing rake, seeder is by rolling land wheel, cantilever shalving, the hopper and the thumb wheel assembly of sowing constitute.

Plough sower according to the spiral saw that such scheme is made, can utilize point of a knife to break ground, soil is carried out the contact of small size earlier, to reduce the resistance of soil; The spiral that utilize to rotate is ploughed blade, makes it from left to right or right-to-left when dividing ditch, can reduce the bounce that the soil blade makes progress; Utilize the sawtooth of blade front edge setting to saw cultivated soil, further reduce the resistance and the bounce of soil blade, plough cutter and can use and adapt to effect with the tractor of low horsepower than the farming of pan soil earth thereby reach spiral saw.And utilize seeder on the machine, can realize that different types of seed program request, row broadcast disposable finishing.Compared with prior art, these facility have simple in structure, plough broadcast the efficient height, easy to operate, adjust flexibly, save time, laborsaving, saving of labor, advantage such as energy-conservation.
