Description

The grass seed drill seeding head

Technical field

The utility model relates to a kind of grass seed drill seeding head, particularly a kind of grassland herbage no-tillage seeding machine seeding head.

Background technology

Chinese patent ZL02251655 discloses a kind of grassland pasture planter, this planter by crane, seed-box, seed tank tower, seed-box lifting screw, nut, penetrate kind of a pipe, syringe needle, syringe needle switch, syringe needle soil-preventing plate and road wheel, towing carriage is formed.This planter is walked under the traction of tractor, earlier the height of seed-box is turned down before the walking, and it is underground that syringe needle is thrust.Walk on one side, Yi Bian seed-box rotates thereupon; Can with grass seeds through penetrate kind pipe, syringe needle is seeded in the soil.But because this planter can not be controlled the quantity of sowing when sowing, at seeding time, when the seed-box rotating speed was fast, syringe needle and ground were short time of contact, and seeding quantity is few; When the seed-box rotating speed was slow, syringe needle and ground releasing time were long, and seeding quantity is many, the even situation of uneven sowing occurred.Its syringe needle switch, the frequent kiss the earth of soil-preventing plate and underground, when sowing on the spot, the syringe needle place is often stopped up by earth, and seed can't flow out, and causes damage easily.

The content of invention

This practical purpose is will provide a kind of and need not out to plough the soil, grassland, not destroy original vegetation and just can sow, seeding quantity evenly, not fragile, reliable grass seed drill seeding head turns round.

The technical solution of the utility model

This grass seed drill seeding head is characterized in suit one sleeve pipe 2 in program request pipe 1, and the front end of sleeve pipe 2 has a convex annular along 4, and a kinds of bank deposits storehouse 8 that convexes to form is arranged on the anterior tube wall of sleeve pipe 2; Promptly have the strip chute 12 of two symmetries with the position that is nested of sleeve pipe 2 at the middle part of program request pipe 1, the rear portion of sleeve pipe 2 promptly be nested position and have the screw 13 of two symmetries of program request pipe 1 with chute 12 corresponding positions; Two screws 14 are arranged in the outside of program request pipe 1 chute 12 is loaded on two screws 13 on the sleeve pipe 2; On the sleeve pipe 2 between the convex edge of the front end of program request pipe 1 and sleeve pipe 2 front ends, a back-moving spring 3 is housed; Be set with a program request 5 in sleeve pipe 2, program request 5 rear portion are grain tube 10, have one in the corresponding position in the front end of grain tube 10 and the kinds of bank deposits storehouse 8 on the sleeve pipe 2 and go out kind of mouth 9, and the front end that goes out kind of mouth 9 in the front portion of program request 5 has a baffle plate 7; The front portion of seeding head 5 be baffle plate 7 front ends with seeding head 5 front ends between have one with kinds of bank deposits storehouse 8 corresponding sides and go out kind of groove 6; One spring 11 is housed between the rear end of the rear end of seeding head 5 and sleeve pipe 2; On sleeve pipe 2, have a chute 15, in chute 15, sleeve pipe 2 and program request 5 is connected with a screw 16.

The utlity model has following advantageous effect:

1, this device seeding quantity is controlled, sowing is even.

2, the repacking interposed structure is reasonable, reliable, not fragile, is well suited for the herdsman and uses.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model rigging position and connection diagram on sower.

Wherein: 1 program request pipe, 2 sleeve pipes, 3 back-moving springs, 4 convex annular edges, 5 program request heads, 6 go out kind of a groove, 7 baffle plates, 8 kinds of bank deposits storehouses, 9 go out kind of a mouth, 10 grain tubes, 11 springs, 12 strip chutes (being positioned at program request pipe both sides), 13 screws, 14 screws (being fixed on the sleeve pipe), 15 chutes (being positioned at sleeve pipe one side), 16 screws (being fixed on the grain tube), 17 kinds of bank deposits tubes, 18 cranes, 19 hitch frames, 20 frames, 21 road wheels.

Embodiment

As Fig. 1, Fig. 2, sower carries out operation under tractor-drawn, need before the operation hitch frame 19 is connected with the draw-gear of tractor, and an amount of grass-seed of in kinds of bank deposits tube 17, packing into, adjust the height of crane 18 simultaneously, it is underground that seeding head 5 is thrust fully, and sower moves ahead under the traction of tractor during operation, kinds of bank deposits tube 17 also rotates thereupon, and program request 5 just takes turns to thrust underground the sowing.When program request 5 near thrusting when underground, stored up in the kinds of bank deposits storehouse 8 and expired seed, that is: because the normal position of program request 5 is outwards to extend stroke foremost, this position makes baffle plate 7 just in time be positioned at 8 lower ends, kinds of bank deposits storehouse, when seed flows into program request pipes 1 because of gravity from kinds of bank deposits tube 17, and then when entering kinds of bank deposits storehouse 8, grain tube 10 can not flow out; When sower continues to move ahead, program request 5 is thrust when underground gradually, because the effect of program request 5 a rear end spring 11, Yi Bian it is underground that program request 5 is thrust, bounce back on one side, plate washer 7 is retraction thereupon also, and the process of plate washer 7 retraction is the process opened of kinds of bank deposits storehouse 8 just, when program request 5 is perpendicular to the ground, when also promptly thrusting underground bosom, open fully in kinds of bank deposits storehouse 8, and the seed edge in the kinds of bank deposits storehouse 8 goes out under kind of groove 6 inflow places, and seed is accurately broadcast in program request 5 pit that sting out; At this moment, baffle plate 7 bounces back to the rear end in kinds of bank deposits storehouse 8, has blocked the outflow of the seed in the grain tube 10, thereby has realized quantitative sowing.Sower continues to move ahead, and underground and ground is progressively left in program request 5, and extends its normal position, is that next round sowing is as preparing.Circulation and so forth, and realize sowing continuously.When seeding head 5 runs into ground not at ordinary times, particularly during the projection of ground, under the effect of convex edge 4, sleeve pipe 2 and program request 5 retraction are to adapt to protruding ground and to finish seeding operation.Under the effect of spring 3, finish after planting sleeve pipe 2 and program request 5 and still can get back to the normal position.
