Description

The film covering type precision sower

Technical field: the utility model relates to a kind of agricultural machinery equipment, specifically relates to a kind of agricultural machinery equipment with trench digging, fertilising, drip irrigation, shop film, earthing, sowing, suppression and intertillage, spraying agricultural chemicals several work function.

Background technology: along with the development and the progress of science and technology of society, agricultural machinery equipment has become indispensable important elements in the agricultural production.For peasant's increasing both production and income, when raising labour productivity, also need select the improved seeds of high yield, high-quality.The selling price of improved seeds is high more a lot of than common variety in the market, so people hope to adopt precision sower to sow.Consumption to reduce seed reduces production costs.Add that northern area arid arable area is more, a lot of places receive the puzzlement of water and influence output.For keeping crop seedling from drought, increasing both production and income all takes film mulching method to cultivate in recent years.Existing overlay film precision sower is made up of plough, fertilizer applicator, irrigate band, seeder, film-covering mechanism, covering device and packer fixing on the frame.Because seeder is in the front portion of film-covering mechanism in this overlay film precision sower; Can only carry out the first mechanical work of overlay film after planting is sowing before the film; Owing to take this mode to carry out after planting, get out the outer growth fast of film for making the seedlings of cereal crops after the germination, also must be artificial on overlay film the correspondence position of sowing punch; This operation seems easily, and land area is big does suitable trouble.Be not only trouble, key is that the hole of being beaten is difficult to the same kind of having broadcast correspondence one by one, so, will certainly influence emergence rate and reduce output.And described seeder is the chain transmission type structure; Very easily blocked in the process of walking by native dirt; Cause the feed mechanism control of forming by contact and duckbilled lever malfunctioning, occur often replaying or cavitation, can't realize precision drilling and service life of equipment is reduced.Also because its covering device of overlay film precision sower is to be hollow cylindrical shell by both sides, establishing the dowel band between two cylindrical shells, be the soil-covered drum of screw feeder and the disk formation of said cylinder both sides in two cylindrical shells.Under the restriction of this soil-covered drum structure, make the earthing area on the mulch film excessive, daylighting property is poor, directly influences seed sprouting and early stage growth.In view of the foregoing; If can develop a kind of needn't Manual punching, guarantee emergence rate, the smart amount of seeder is controlled reliably; Covering device can make mulch film not only preserve soil moisture but also printing opacity, promotes the film covering type precision sower of seed sprouting and early stage growth to become agricultural mechanical field technical barrier anxious to be solved.

Summary of the invention: the purpose of the utility model is to provide a kind of film covering type precision sower; Mainly be on overlay film, to punch in order to solve the manual work that after planting also needs that exists in the prior art; Punch be difficult to having sowed son corresponding; Seeder can not be realized precision drilling, and covering device earthing area is excessive, directly influences the problem of emergence rate, output and farmers' income.

The technical scheme of the utility model is described below: this utility model comprises mainframe, secondary frame, fertilizer applicator, plough, irrigate band, seeder, overlay film frame, press mold wheel, covering device, press wheel combination and chemical sprayer, feeler mechanism, strainer, intertillage parts; It is through the covering device combination that gear ring driven type cylinder seeder and soil-covered drum with bar shaped earthing function and disc covering device constitute is set, and seeder is arranged on rear portion realization that film-covering mechanism and covering device make up.

This utility model compared with prior art has the following advantages and good effect:

1, owing to is provided with gear ring driven type roller seeder; The eccentric gear of in roller, establishing gear ring and meshing with gear ring has changed original working environment, has effectively avoided the jam phenomenon; Reliably realized accurate control, precision drilling is fulfilled feed mechanism.

2, owing to be provided with soil-covered drum with bar shaped earthing function; Enforcement is to the earthing of seedling eye, and the earthing area that has overcome existing covering device existence is excessive, the disadvantage of lighting performance difference; And help soil moisture conservation, created good condition for promoting seed sprouting and early growth.

3, owing to the rear portion that the cylinder seeder is arranged on the combination of film-covering mechanism and covering device; What implement is the working method of sowing behind the first overlay film; Its outstanding feature be seeder in the process of walking its seeding duckbilled directly pass earthing and rete seed broadcast into; Can guarantee the corresponding of fenestra and hole, ground (seed that is equivalent to sow); Make the growth of directly from the hole that duckbilled passed, emerging behind the seed sprouting, thereby guarantee that precision drilling goes out full stand, exempted the manual work trouble caused of on overlay film, punching simultaneously.Kill two birds with one stone.

4, this machine is reasonable in design multiple functional; Can not only apply fertilizer (comprise deep placement base fertilizer with topdress), overlay film, earthing, sowing, suppression; And be provided with irrigate band, chemical sprayer, intertillage parts; Carry out drip irrigation, spray agricultural chemicals, ridging and intertillage operation, be more suitable for the arid area and use, satisfy the needs of high-grade seed complete stool distance, simple grain, equidistant program request.

5, the major and minor frame of this machine all adopts square tube to be connected with various links; Easy to adjust up and down; And be furnished with accessories such as feeler mechanism, strainer and seed plate (seed dispenser), intertillage parts, and make the complete machine function admirable, use more flexible.

6, this machine also has inventive concept novelty, complete machine compact in design, stable work in work, increases the service life, is fit to advantages such as popularization in the industry.
