Embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1 and Fig. 2, have and prevent that seed from becoming the sower of the empty swing mechanism of bow member to comprise frame 1, Seeding box 2, eight seed distributing grooves 10 and transmission mechanisms.Eight seed distributing groove 10 uniform 2 liang of side bottoms of Seeding box that are installed on; Feed shaft 12 levels run through each seed distributing groove 10, feed shaft 12 is installed on the frame 1 by bearing 18, bearing block 17, be positioned on the feed shaft 12 of seed distributing groove 10 seeding gear 11 is installed, the chain-drive mechanism that feed shaft 12 middle parts are formed by drive sprocket 4, chain 5 and feed shaft sprocket wheel 6 is being connected the reductor 3 that is positioned at frame 1 bottom.

Seeding box 2 internal upper parts are equipped with swinging axle 27, swinging axle 27 parallel and feed shafts 12; Swinging axle 27 middle parts are equipped with swing arm 26, and the swinging axle 27 of swing arm 26 both sides is installed on the Seeding box casing by fixed hub 28; The lower end of swing arm 26 is connecting steel wire rope 25, and steel wire rope 25 straddles on the pulley 24, and swing arm 26 lower end opposite sides are connecting spring 33, and the other end of spring 33 is fixed in the Seeding box inwall; Pulley 24 is installed on the wheel shaft of eccentric wheel 22 by bearing and jump ring 23; An axial side of eccentric wheel 22 is connecting an end of power transmission shaft 21, power transmission shaft 21 is installed in the transmission case casing 15 by bearing and bearing block, the chain-drive mechanism that power transmission shaft 21 is formed by power transmission shaft sprocket wheel 9, driving chain 8 and input sprocket 7 is being connected feed shaft 12, and power transmission shaft 21 parallel and feed shafts 12.

Swinging axle 27 both sides corresponding with seed distributing groove 10 are equipped with four connecting rods by set bolt 32 respectively, and the lower end of connecting rod is connecting swing arm 30 by adjusting nut 31.

Distance between 30 times end distance seed distributing groove 10 upper ends of swing arm is the 10-130 millimeter, can pass through adjusting nut 31 adjustable ranges.

Above-mentioned power transmission shaft sprocket wheel 9, driving chain 8, swing input sprocket 7; Power transmission shaft 21, eccentric wheel 22, pulley 24, steel wire rope 25, swinging axle 27 and swing arm 30 formations prevent that seed from becoming the empty mechanism of bow member;

Swing input sprocket 7 uses key to be connected with sower axle sleeve 19, is intended to obtain axle sleeve 19 power that provides is provided, and this is the source of the power of whole system; Swing input sprocket 7 drives 9 rotations of power transmission shaft sprocket wheel by driving chain 8, drives the eccentric wheel 22 that links together equally by connected power transmission shaft 21 during 9 rotations of power transmission shaft sprocket wheel and rotates eccentric wheel 22 rotating band movable pulleys 24 eccentric swings; Pulley 24 is connected by steel wire rope 25 with swing arm 26, and the lower end of swing arm 26 simultaneously is fixed on elasticity 33 tractions of Seeding box cylinder body 2 one sides all the time, and when eccentric wheel 22 lower ends during near spring 33, spring 33 pulls to swing arm 26 lower ends away from the eccentric wheel direction; When eccentric wheel 22 far-ends during away from spring 33, the effect that steel wire rope 25 overcomes spring 33 pulls to a side away from spring 33 with swing arm 26 lower ends, and swing arm 26 lower ends have just produced reciprocal swing like this, see Fig. 3 and Fig. 4; Swing arm 26 upper ends are connected with swinging axle 27 by set bolt 32, and when swing arm 26 lower ends produced reciprocal swing, swing arm 26 upper ends then forced swinging axle 27 back and forth to rotate thereupon; The result that swinging axle 27 back and forth rotates forces swinging connecting rod 29 upper ends that are attached thereto back and forth to be rotated, and is delivered to swing arm 30 lower ends and has become reciprocally swinging, sees Fig. 5 and Fig. 6.Utilize the reciprocally swinging effect of swing arm 30, the seed of the arch of hardening at seeding notch place is scattered under the effect of swing arm 30 oscillating motions easily, the seed after scattering enters seeding gear 11 places in the seed distributing groove naturally under action of gravity.

The operation principle of this sower is as follows:

Before the sowing seed is put into Seeding box casing 2, seed is because action of gravity partly enters seeding gear 11 places in the seed distributing groove 10, decelerator 3 drives drive sprocket 4 in the sower traveling process, drive sprocket 4 drives axle sleeve 19, feed shaft 12 and seeding gear 11 by chain 5 and feed shaft sprocket wheel 6 and rotates simultaneously, when the seed in seeding gear 11 forwards the bottom to, because of the action of gravity seed leaves seed distributing groove 10, reach the purpose of sowing.

Under the device reliable premise, whether can finish sowing, just depend on that seed can enter into seeding gear 11 by action of gravity smoothly.Seed hardens because of being soaked to cause swelling through regular meeting in the sowing process of reality, becomes the bow member sky above seed distributing groove 10, can not enter seeding gear 11, causes the phenomenon of broadcast leakage to produce.The present invention has increased a whole set of anti-seed and has become the empty device of bow member on the basis of regular drill, be intended to become the problem of bow member sky by reliable device solves seed, but not only rely on action of gravity, and guarantee that seed is stable, successfully enter seeding gear 11, reach the purpose of precision drilling.
