Description

The fertile sower of wheat deep placement

The utility model is a kind of sowing, the fertile seeding apparatus of the wheat deep placement that fertilising is simultaneously used of being used for about agricultural machinery.

At present, wheat fertilizing sowing, great majority are kind, fertilizer is blended on the same bed, and the shortcoming of this method is that the seed waste is serious, and chemical fertilizer utilization ratio is low, and the burning kind that easily industry is serious, burns the seedling phenomenon.

The objective of the invention is to overcome shortcoming of the prior art, provide a kind of chemical fertilizer utilization ratio height, seed to endanger less, produce the fertile sower of low, the easy to operate wheat deep placement of investment.

The purpose of this utility model be achieved in that the fertile sower of wheat deep placement by frame, wheel assembly, running part, seed manure case, plough, earth backing device form.Frame is made up of girder, auxiliary girder, left and right sides Shun Liang, last hanger bracket, lower suspension arm, land wheel support arm axle sleeve, the dark leading screw of limit and screw, hanging wheel iron.Frame is attached on the tractor by last hanger bracket, lower suspension arm, limited dark leading screw and screw on suitable beam about frame.The land wheel assembly part is positioned at the frame both sides, is made up of land wheel, cleaning shoe, support arm, support arm shaft, hanging wheel bar, bearing block, land axle, drive sprocket, bearing, bearing cap, expansion link, buting iron, compression spring.Land wheel has ground lug, support arm shaft pierces in the support arm axle sleeve of frame, fix with pin, the hanging wheel bar inserts in the hanging wheel iron of frame, and expansion link one end inserts support arm, the other end is connected with buting iron, be with compression spring on the expansion link, drive sprocket is installed on the land axle and fixes with pin, and land wheel is fixed on the land axle by bearing, bearing cap, support arm, bearing block, cleaning shoe are welded as a whole, and buting iron inserts in the hole of seed manure case foreleg.Running part is made up of square frame chain, regulating wheel, rocking arm, extension spring, passive sprocket wheel.Used square frame chain drive between movable sprocket and the drive sprocket, along in the hole of beam, the upper end was unsettled about the rocking arm lower end was connected in, and be pressed on the chain, and there was regulating wheel the upper end, and along beam, the other end was connected on the rocking arm about extension spring one end was connected in.The seed manure case by case nation, case at the bottom of, plug, central dividing plate, case lid, case foreleg, case back leg, seat watt, fertilizer sprocket, seeding sprocket, seeding, fertilizer expelling shaft, horizontal iron, regulate screw and form.Fertilizer sprocket, seeding sprocket lay respectively at the outside of plug, and seeding, fertilizer expelling shaft cross two plugs, are connected with nut along between the beam about horizontal iron and frame, and seeding, fertilizer apparatus have some discharge openings, and the adjusting screw is installed in the outside of sprocket wheel.Applicator boot is made up of disk, bearing block, bearing, bearing holder (housing, cover), little axle, spindle nose cap, bearing cap, fertilizer delivering pipe, opener shank, plough solid, gib, card silk, backplate.Gib is stuck on the girder of frame, and with the locking of card silk, gib, opener shank, plough column are welded as a whole, disk is installed on the opener shank by bearing, the fertile tube head of the wheel that is connected with seed manure case fertilizer delivering pipe is stretched down between two disks, and two disks are staggered front to back installation, and the tip forward.Seed opener is made up of disk, bearing block, bearing, bearing holder (housing, cover), little axle, spindle nose cap, bearing cap, seeder, opener shank, plough column, gib, card silk, backplate.Gib is stuck on the auxiliary girder, with the locking of card silk, gib, plough column, opener shank is welded as a whole, and disk is installed on the opener shank by bearing, and the bottom of the seeder that is connected with seed manure case seed outlet is divided into two seed outlets, stretch between two disks, two disks are staggered to be installed, the tip forward, stagger angle is different with applicator boot.The earth backing device is made up of connecting plate, spring pin, compound soil plate, axostylus axostyle, buting iron, torque spring.Along on the beam, the axostylus axostyle frame was on connecting plate about connecting plate was installed in, and the spring pin is positioned at axostylus axostyle top, and buting iron is connected with torque spring, is pressed on the compound soil plate, and compound soil plate, torque spring are installed on the axostylus axostyle.

The present invention compared with prior art has following good effect:

1, improves chemical fertilizer utilization ratio, save seed.Fertilising, seed opener is fixedly connected respectively on frame, makes chemical fertilizer and seed be maintained fixed distance.

2, avoid burning kind, burn the generation of seedling phenomenon.

3, reduce the production investment.

4, change the line-spacing of plough, can also other crop of drilling.
