Description

Seeder with fertilising apparatus

The utility model relates to a kind of combined seed and fertilizer drill, is to be applicable to the essence of corn, soybean, to reach the agricultural machinery of many of large tracts of land (about 3) sowings on a small quantity.It can make trench digging, fertilising, sowing, suppression, earth backing five processes once finish, and is the small-sized manure-spreading and seeding machine that can finish supporting operation that optimum is articulated by tractor with small four wheels (power mostly is 12 horsepowers greatly at present).

In prior art, have only large and medium-sized manure-spreading and seeding machine can all execute the supporting operation of broadcasting each operation, and the vast rural area of China still be in the small peasant economy stage contract, allocate land on the household base owing to the dispersion in soil and at present the multiple reasons such as restriction of household economy condition still can not large-scale popularization adopt large and medium-sized manure-spreading and seeding machine.Can only finish wherein part operation and existing small-sized manure-spreading and seeding machine has, still need and drop into certain manpower assistance, when trench digging of existing that has routed up wet soil and upsets soil layer and influence soil moisture content, during the fertilising that has fertilizer is sprinkling upon seed or upper soll layer cause burn kind and fertilizer loss so that seedlings of cereal crops fertilizer deficiency weedy, the sower seeding quantity that has is uneven in addition break up, squeeze crack, serious, the poor reliability of wound kind, the not suppression mechanism that has, seed both sides soil do not have compacting and often jam-packed so that the crops growth that is difficult to emerge of seed end face.In a word, current small-sized manure-spreading and seeding machine exist shortcoming and problem a lot, need badly and improve the manure-spreading and seeding machine novel with development.

The purpose of this utility model provides a kind of small-sized manure-spreading and seeding machine that can once finish trench digging, fertilising, sowing, suppression and earth backing five processes that is articulated traction by tractor with small four wheels.Do not upset soil layer when when operation, accomplishing to ditch, fertilising is evenly reliable in deep, the seed outside, sowing, the injuring-free seed grain also is provided with the packer feeler mechanism and can makes the manure-spreading and seeding machine can the translation with the rugged wavy shape in soil surface, accomplishes that suppression and earth backing comparatively suitably reaching rationally.

A kind of combined seed and fertilizer drill of the utility model, it is to be connected the tractor back by hanging device, on its frame, plough is installed, fertilizer applicator, seeder, packer and soil covering implement are formed, it is characterized in that its plough is with plough ［ 14 ］ and be positioned at the darker fertilising of its side, the place ahead digging and constituted with plough ［ 2 ］ by the sowing of the clean-up scraper that has spring ［ 7 ］, sheave ［ 36 ］ in its fertilizer applicator ［ 34 ］ and the vertical panel spoon formula disk ［ 28 ］ in the seeder ［ 25 ］ pass through chain ［ 24 ］ driven rotary by the sprocket wheel ［ 19 ］ on the packer ［ 16 ］, its packer ［ 16 ］ is the press wheel that has ratchet ［ 21 ］ ［ 20 ］ that the heavier periphery of weight is concave surface, and top is equipped with fertilizer applicator ［ 34 ］ and seeder ［ 25 ］, packer ［ 16 ］ is equipped with at the rear portion, tail end drags its front end of frame ［ 15 ］ of soil covering implement ［ 22 ］ to be provided with feeler mechanism ［ 8 ］ to be connected with hanging device ［ 1 ］.Its feeler mechanism ［ 8 ］ be two groups can interleaved activity but remain the last connecting rod ［ 11 ］ and the lower link ［ 12 ］ that are parallel to each other and constitute, the front fulcrum pin ［ 10 ］ of upper and lower connecting rod ［ 11 ］, ［ 12 ］ is installed on the right cylinder ［ 9 ］ of hanging device ［ 1 ］.The rear fulcrum pin ［ 10 ］ of upper and lower connecting rod ［ 11 ］, ［ 12 ］ is installed on the curved column ［ 13 ］ of frame ［ 15 ］, and the chain ［ 24 ］ of sprocket wheel ［ 19 ］ can be by the idle pulley adjustment on the adjusting device ［ 23 ］.

The utility model compared with prior art can make trench digging, fertilising, sowing, suppression, earth backing five processes one-time continuous finish, and it takes lengthwise gulley can accomplish to keep respectively surperficial dry ground and bottom wet soil level, keeps soil moisture content good.It can be applied to the about 6cm of the side of the seed to fertilizer and on the lower side on the fertilizer efficiency optimum position of 2cm, its adopts vertical panel spoon formula disk seeding unit, and seeding evenly reliably, does not damage kind of a grain.It is the packer of spill circumference in the middle of adopting, and makes seed two side compressions and keeps soft above the seed and be convenient to the seedlings of cereal crops and grow.It adopts the packer feeler mechanism that manure-spreading and seeding machine is risen and fallen and parallel moving with the face of land, keep seed and chemical fertilizer apart from face of land degree of depth basically identical, and feeler mechanism can also be by last connecting rod ［ 11 ］ and support lean the contact preventing facility, cancelled the spacing suspension rod of old type farm implements, the utility model also can be used for sowing as granule crops such as jowar.
