Description

Cultivator-fertilizer

Technical field

The utility model relates to a kind of farm implements, promptly a kind of cultivator-fertilizer that is suitable for dry land ridge culture crop such as corn intertillage topdressing operation.

Background technology

Crop such as corn, Chinese sorghum, the big multicast of seed and at crops seedling stage, to the both sides earth backing, make original furrow become the ridge platform with plough in trench digging in the ranks furrow during sowing.This process is called intertillage.In recent years, the peasant carries out fertilizer dressing simultaneously when intertillage, exactly chemical fertilizer is sprinkling upon between crop row, and the earth backing of having ploughed covers chemical fertilizer, can avoid volatilization, increases fertilizer efficiency.Be used to intertill the facility that topdress the single-row machine that draws of poultry and the multirow facility of power traction are arranged.Along with the raising of mechanization level, the power traction facility have replaced poultry to draw facility gradually.Existing power traction cultivator-fertilizer has the fertile case of a cuboid on hitch frame, have the defertilizing wheel of controlled flow below the fertile case, connects two to a plurality of plow beams on the crossbeam of hitch frame, and plow beam is equipped with ploughshare below by plow standard.In addition, in the hitch frame both sides, a land wheel is often arranged respectively, on one of them land axle sprocket wheel is arranged, the defertilizing wheel above driving by chain rotates.Mainly there are following three problems in this facility: the one, and each plough body has only a ploughshare, and is darker at trench digging, and under the situation of travel faster, the soil of having weeded and loosen the soil is difficult for broken, can form soil block.Soil block can weigh the seedlings of cereal crops wounded, pulls apart crop root, can form bigger slit again, quickens the volatilization of chemical fertilizer and the loss of moisture.The 2nd, wheel drive can influence the stability of fertilizer because of skidding unilaterally.The 3rd, the crack, ground of the crossbeam of hitch frame is lower, can not advance the ground operation when crop is higher.

Summary of the invention

It is thinner that the purpose of this utility model provides a kind of earth backing, and fertile amount is even, the cultivator-fertilizer that the crack, ground is higher.

Above-mentioned purpose is realized by following technical scheme: develop a kind of cultivator-fertilizer, formations such as hitch frame, fertile case, land wheel, fertilizer mechanism, plow beam and ploughshare are arranged, be characterized in: on the crossbeam of hitch frame, clamp three plow beams, former and later two ploughshares are all arranged on each plow beam, each ploughshare is installed on the plow beam by plow standard, and the setting height(from bottom) of plow standard is adjustable, and the position of front ploughshare share beak is higher than the share beak position of rear ploughshare.

The position of said front ploughshare share beak is higher than the share beak position 50-100mm of rear ploughshare.

Two land wheels of said both sides all are equipped with sprocket wheel in wheel shaft outer end separately, and the same defertilizing wheel axle below two chains and fertile case is formed transmission respectively, drive same defertilizing wheel axle from both sides and rotate.

There is one section downward bending at said plow beam rear portion, and there is the socket that matches with the back plow standard bending back.

Adopt the cultivator-fertilizer of such scheme, owing to adopted the ploughshare of former and later two differing heights, can reach tilling depth at twice, even the gait of march of facility is higher, earth backing is also more in small, broken bits, is difficult for forming soil block, thereby has improved efficient, reduced and hindered the seedling phenomenon, improved the ability of preserve moisture and fertility.Owing to adopt two transmission land wheels, reduced total slip rate of land wheel, strengthened the stability of fertilizer, make fertilizing amount evenly accurate.The installation rigidity of back plow standard has been strengthened in the bending of plow beam back segment, and makes the crack, crossbeam ground of having improved hitch frame, thereby can adapt to the higher seedlings of cereal crops, has prolonged the intertillage operation time limit.

Embodiment

As shown in the figure, the fertile case 1 of this cultivator-fertilizer is contained in above the crossbeam 3 of hitch frame 2, have three defertilizing openings 12 at the bottom of the case of fertile case 1, following 15, three defertilizing wheels 15 of an outer groove wheel defertilizing wheel that all are equipped with of each defertilizing opening 12 are through on the defertilizing wheel axle 14.Defertilizing wheel 15 is made up of one section sheave and one section circle wheel, turns the handwheel 16 of defertilizing wheel axle one end, and defertilizing wheel axle 14 can move vertically, and drive defertilizing wheel 15 moves and adjusts defertilizing amount.Owing to belong to routine techniques, the structure of handwheel is not drawn one by one.Respectively there is a sprocket wheel 22 at two of defertilizing wheel axle 14, forms transmission with the sprocket wheel of land wheel 6 axle heads of both sides respectively by two chains 7.Land axle is contained on the land wheel post 5, and two land wheel posts 5 are inserted into respectively on the socket 19 of both sides plow beam 4 inboards, and anti-skidding ground tire 21 is housed around the land wheel 6.Need to prove: the land axle here should be equipped with bearing, otherwise, when two land wheels rotate synchronously, can sprain defertilizing wheel axle 14.After bearing is installed, rotate flexibly, can drive mutually and keep run-in synchronism.Except above-mentioned two land wheels 6 drive the same defertilizing wheel axle 14, another important improvement is that former and later two plow standards and two ploughshares are housed on plow beam 4, and two plow standards all are jack 19 the insides that are inserted into plow beam 4, and adjustable height is by jackscrew 13 location.During work, the share beak of front ploughshare 8 must be higher than the share beak of rear ploughshare 10.In general, preceding share beak should reach tilling depth 1/2nd to 1/4th between, the share beak of rear ploughshare 10 should reach the tilling depth extreme position.With tilling depth 200mm is example, and the discrepancy in elevation of front and back two ploughshares should be between 50-100mm.Like this, when farm work, same tilling depth is divided into twice to be finished, and the soil of having ploughed is much more broken than what once ploughed, and its airtight performance is better, and the effect meeting of preserve moisture and fertility is stronger, and the gait of march of facility also can be faster.In addition, a downward bending 20 is arranged, make the position that is installed of plow standard lower, to strengthen stability at the latter end of plow beam 4.This routine bending 20 makes the end of plow beam 4 500-200mm that highly descends, and has equaled to improve the height of hitch frame crossbeam 3.Because crossbeam is across three row crops, the height deficiency of crossbeam will blow down the seedlings of cereal crops, has increased height, both can reduce and hinder seedling, can prolong the time limit of intertillage again, slows down the pressure of intertillage.Have: adopt " U " type gib 17 and bolt and jackscrew 13 to make up in this example between plow beam 4 and the crossbeam 3, the work line-spacing can be adjusted arbitrarily between 500-600mm again.For the ease of clearing up the residue chemical fertilizer of fertile case 1 the inside, below fertile case, also be provided with clear fertile mouthful 18 of board plug type, insert plate when closing, tighten jackscrew and get final product, when needing cleaning, turn on jackscrew, extract plate out, can leak the chemical fertilizer in the clean case.
