Abstract

The utility model relates to a disk ditching machine for a seeder, and belongs to the technical field of farm machinery. The utility model is used for providing a disk ditching machine for a seeder, which is good in seeding quality and reliable in work. The utility model is comprises a couple of disks, a pillar and buffer springs, wherein the edge of each disk is provided with a soil scraping plate which is installed on the pillar. The edges of the two disks of the ditching machine add an inner soil scraping plate and an outer soil scraping plate. A soil blocking plate is added between the two disks. When a seeder is used for seeding, soil attaching to the disks is scraped off by the inner soil scraping plate and the outer soil scraping plate, and large soil blocks clamped between the two disks are blocked by the soil blocking plate and falls off. Thus, seeds sown by the seeder can not be blocked by soil or weeds adhering to the disks but can accurately fall into a groove ditched by the ditching machine; the depths of the groove are homogeneous and the sown seeds are concentrated and orderly. The utility model has the advantages of good seeding quality and reliable work, and the seeds do not miss to be sown in some positions of the groove. In addition, the buffer springs adopt dual springs, so the buffer springs can have reliable buffer action and further increase the seeding quality.

Description

The sower disk coulter

Technical field

The utility model relates to a kind of sower disk coulter, belongs to the agricultural machinery technology field.

Background technology

At present, the sower that uses of people comprises pair disk, pillars during it constitutes with disk coulter and is sleeved on single cylindrical helical compression buffer spring on the pillar etc.Its advantage is simple in structure; but weak point is when sower is worked; run into wet soil, or soil property viscosity can adhere to earth on the disk of its plough when big; and the working time is long more; the soil layer that adheres to is thick more, usually can carry soil block secretly between two disks, and the seed that falls when these all can make sowing is obstructed; can not fall exactly in the groove that plough leaves, influence emergence rate and field management in the future.In addition, the rigidity of its single cylindrical buffer spring is excessive, and when running into uneven soil, buffering effect is poor, and this also can influence seeding quality.Therefore, existing sower disk coulter haves much room for improvement.

Summary of the invention

It is good that technical problem to be solved in the utility model provides a kind of seeding quality, the sower disk coulter of reliable operation.

It is as follows to address the above problem the technical scheme that is adopted:

A kind of sower disk coulter, it comprises pair of discs, column and buffering spring, and said disk 1 edge is provided with clean-up scraper, and clean-up scraper is installed on the column 4.

Above-mentioned sower disk coulter, said clean-up scraper are two interior clean-up scrapers 15, are located at 1 in two disks, two interior clean-up scrapers 15 are hinged with same hinge 6, and hinge 6 is loaded on the support 5, and support 5 is fixing with backplate 8, backplate 8 is fixing with column 4, and two 15 of interior clean-up scrapers are provided with torsionspring 7.

Above-mentioned sower disk coulter, said disk 1 are provided with two outer clean-up scrapers 13, and outer clean-up scraper 13 is located at the outside of two disks 1, and each is hinged with a hinge 12 for two outer clean-up scrapers 13, is provided with torsionspring 14 therebetween, and hinge 12 is fixing with backplate 8.

Above-mentioned sower disk coulter, 1 in said two disks are provided with breast boards 2, and the inner end of breast boards 2 and column 4 are fixing.

Above-mentioned sower disk coulter, said buffer spring is two cylindrical screw compression buffer springs 17, two springs 17 respectively are sleeved on the traveller 3, be placed in the abreast both sides, front and back of column 4 of two travellers 3, its lower end and column 4 are fixing, and column 4 upper ends are set with flanged 10 sliding sleeve 9, and the slip ring 18 that sliding sleeve 9 front and back are fixed is set on two travellers 3, slip ring 18 contacts with spring 17 upper ends, and traveller 3 upper ends are provided with adjusting nut 11.

Above-mentioned sower disk coulter, said buffer spring 17 is provided with dirt-proof boot 16, and dirt-proof boot 16 upper end end sockets place between slip ring 18 and the spring 17.

Sower disk coulter provided by the utility model is the improvement on former plough basis, in two disk border places of plough have set up, outer clean-up scraper, between two disks, set up breast boards, like this, when sower is sowed, at any time scraped by inside and outside clean-up scraper attached to the earth on the disk, being clamped in bigger soil block between two disks is blocked by breast boards and falls, therefore, things such as earth that the seed that sower is sowed can not adhered to by disk or weeds stop, can fall exactly in the groove that plough leaves, weight is more even, in the subset of sowing, standard, seeding quality is good, disconnected ridge phenomenon can not appear in reliable operation, sowing.In addition, its buffer spring adopts dual spring, like this, when when planting with sowing machine, running into rugged ground, the safer cushioning effect that plays reliably, the groove weight that plough is left is consistent to large extent, further improves seeding quality.
