Abstract

The invention relates to a soil-covering device of a seeder, in particular to a soil-covering device of a dotted seeder. The soil-covering device comprises a soil-cutting wafer (4), a soil-covering roller (2) and a soil-scraping plate brush (1), wherein the soil-covering roller (2) is provided with a soil outlet (5). The soil-covering device is characterized in that the soil-covering roller (2) is provided with a membrane-cutting knife (3). Compared with the prior art, the soil-covering device provided by the invention has the advantages of simple structure, accurate and uniform soil covering and good operation effect, can carry out seed-row gap-cutting on membranes paved after seeding and accurately cover soils on gaps aiming at the current dibble seeding or row planting modes, and then the soils is flatted by the brush, so that the daylighting surfaces of seed rows are ensured under the condition of complete soil moisture conservation, and the seedlings can naturally pass through the membrane, thereby improving the quality of seedling emergence. The soil-covering device is suitable to be used in various membrane-covering seeders.

Description

Dotted-line style sower covering device

Technical field:

The present invention relates to a kind of sower covering device, particularly a kind of dotted-line style sower covering device.

Background technology:

In the plantation of present film-mulching cultivation, after planting generally all will be on mulch film earthing, uncovered by wind to prevent mulch film, after emerging, need to put the seedling operation, labour intensity is big, inefficiency often occurs because of in time not putting the situation that seedling is scalded cotton seedling.Therefore in cotton planting, adopted program request technology on the film in a large number, but following problem has also appearred in program request on the film: the one, and the bigger easy evaporation of water in soil of dibbling pore volume appears, so after planting also need run into rainwater owing to the kind hole that dibbler caused is sagging in addition and also the phenomenon that hardens may occur at sowing kind of place, a hole earthing.

Chinese patent CN2917222Y discloses a kind of sower covering device, comprise and cut native disk, soil-covered drum, be provided with the scraping scrubbing brush behind described soil-covered drum, described soil-covered drum front portion is provided with and comprises the film cutting apparatus of cutting membrane cylinder and cutting membrane knife, has solved the problems referred to above preferably, but structure relative complex, cut film and earthing simultaneously and carry out respectively, earthing situation not in place usually occurs, cover as leakage etc.

Summary of the invention:

The purpose of this invention is to provide the sower covering device that a kind of structure is simple in structure, earthing is even, operation effectiveness is good, particularly a kind of dotted-line style sower covering device.

The present invention includes and cut native disk (4), soil-covered drum (2) and scraping scrubbing brush (1), soil outlet (5) is arranged on the soil-covered drum (2), it is characterized in that described soil-covered drum (2) is provided with cutting membrane knife (3).

The edge of a knife of above-mentioned cutting membrane knife (3) is preferably a kind of in circular arc, triangle or the wedge

Above-mentioned cutting membrane knife (3) is preferably arranged between the different lines of soil-covered drum on one week alternately.

The soil outlet of above-mentioned soil-covered drum (5) preferably is mesh-like.

Compared with prior art, covering device of the present invention is simple in structure, earthing is accurately even, operation effectiveness is good, can be at present program request or drilling, behind the film of sowing shop, planting row joint-cutting and earthing on institute joint-cutting crack exactly on the film, through brush soil is applied flatly, under the situation of fully soil moisture conservation, make kind of a row guarantee a daylighting face, can also allow the seedling can natural membrane, improve the quality of emerging, be suitable for various mulch film spreading and seeding machines and use.
