Description

The precision film covering seeder

The utility model relates to a kind of sowing parts, specifically a kind of seeder of Mulching and hill-drop sowing machine.

Present wheat Mulching and hill-drop sowing machine, the ubiquity sowing is irregular, because seed can not enter duckbilled institute extremely equably, thereby it is very big to cause the seed grain of broadcasting in the cave to count difference, promptly few only has three or four, and many then has more than 20, can not satisfy the production requirement of mulch sowing.

The purpose of this utility model is to design a kind of precision film covering seeder, and this seeder is provided with quantitative plectrum mechanism on the seeding rotating disk, thereby seeding is even, in order to overcome existing deficiency with the seeder on the hill-drop planter.

The utility model can reach by following embodiment:

The utility model is made up of seeding rotating disk, seeds discharging box, main shaft, pull bar.

Seeding rotating disk shape such as steamer steering wheel, just the handle at the place of holding is a duckbilled.Duckbilled has several, is evenly distributed on the seeding rotating disk circumference.The duckbilled inner chamber with have in big outer little infundibulate seeding passage communicate, its inclined-plane one side has duckbilled tongue and spring.There is toroidal cavity at seeding rotating disk middle part, for put seeds discharging box in it.A moving tooth circle is adorned in seeding rotating disk left side, and a circle moving tooth post is arranged on the moving tooth circle end face.

The box body of seeds discharging box is made by sheet member, and two ends are planar annular, and the middle part has coaming plate to be connected, and inner chamber is a ring body of behaveing affectedly.One of the riveted in left end middle part, box chamber connects dish, and the son tube is revealed in one of top welding, reveals sub-barrel shape and resembles the diesel engine intake bend pipe, and inner chamber communicates with the box chamber, establishes feed mechanism in the seeds discharging box.The gear teeth, feed shaft, plectrum wheel are arranged on the feed mechanism.The feed shaft box chamber of packing into, dress plectrum wheel on the axle, axle is worn a finger with the keyway of plectrum wheel endoporus, the dress gear teeth and use nut fastening on the spindle nose that stretches out box chamber left end.Hairbrush, scraper plate, sealing plate are arranged on the sowing port coaming plate, and paste with plectrum wheel circumferential surface.Be evenly equipped with several hemispherical depression on the plectrum wheel circumference, double-screw bolt is arranged at the recess bottom, in order to adjust deep diving.

Extension bar has two, the outer appearance connecting rod, and two ends are porose.There is pull bar at the main shaft two ends, and with screw rod locking, there are seeding rotating disk, seeds discharging box in the main shaft middle part.On main shaft, its box chamber puts in the seeding rotating disk toroidal cavity seeds discharging box left end with screw lock, makes the gear teeth on the seeds discharging box be meshed with moving tooth post on the moving tooth circle.During sowing, the seeding rotating disk rotates on main shaft, and plectrum wheel was driven by the gear teeth and did rotation synchronously this moment, by the recess on the plectrum wheel, a brood of seed is transferred to next from the box chamber, is disposed to funnel-shaped passage and enters duckbilled.When duckbilled was gone into the cave seeding, the duckbilled tongue opened automatically, and a brood of seed is entered in the cave.When duckbilled was extracted the acupuncture point out, the duckbilled tongue was closed automatically because of being subjected to the spring force effect.

The gear teeth of the present utility model, plectrum wheel, moving tooth circle are for moulding product firmly, and all the other are metallic article.

Advantage of the present utility model is for having set up seeds discharging box and feed mechanism, thereby novel structure, and plectrum is even, and can make full use of seed and save seed, and can the reasonable use soil fertility, be a kind of desirable precision film covering seeder.

Below in conjunction with accompanying drawing the utility model is done detailed description further.

By Fig. 1--shown in 6, this seeder is made up of seeding rotating disk, seeds discharging box, main shaft (11), pull bar (12).

Seeding rotating disk shape such as steamer steering wheel, wheel rim (4) and wheel disc (7) they are the thin plate products, uniform several holes on its circumference is a rigid backbone with tube connector (5) and the hole assembly welding that joins.In wheel disc (7), be welded with funnel (6) on the cinclides, funnel shaped be in side, cylindrical, wheel hub (9) penetrates wheel disc (7) endoporus and phase riveted in the plane.Moving tooth circle (8) is fixed on wheel disc (7) left end along on the face with sunk screw, a uniform circle moving tooth post on the end face of moving tooth circle.Between funnel (6) and wheel hub (9), a ring cavity is arranged, hold the seeds discharging box chamber for it.Duckbilled (1) has several, is fixed on wheel rim (4) periphery with button-headed screw, and its inner chamber communicates with funnel (6).Duckbilled (1) plane one side dress duckbilled tongue (2) connects with tack pin (3).Between duckbilled tongue (2) and wheel rim (4), be connected spring (10).

The box body of seeds discharging box is formed by the metallic article assembly welding.On box chamber base plate (23) its right end face, be welded with coaming plate (13), sealed tube (15), its left side connects one and connects dish (22) and phase riveted in the plane, and son tin (24) is revealed in the top welding.Adorn end cap (14) and tighten up with sunk screw on sealed tube (15) convex shoulder plane, the indoor chamber of box in the form of a ring.

The indoor feed mechanism that is provided with of seeds discharging box.Feed mechanism has the gear teeth (18), feed shaft (20), plectrum wheel (21).Feed shaft (20) penetrates in two holes, box chamber, and finger (17), plectrum wheel (21), shaft retaining ring (16) are arranged on the axle, and finger (17) penetrates in the plectrum wheel inner hole key slot.The gear teeth (18), steady pin (19) are housed on the left end spindle nose of box chamber and use nut check stretching out.Be evenly equipped with several hemispherical depression on plectrum wheel (21) circumference, the double-screw bolt (27) of adjusting deep diving is arranged in the recess.On the box chamber seeding outlet coaming plate (13) hairbrush (25) is housed, scraper plate (26) and sealing plate (28), and take turns (21) circumferential surface with plectrum and paste mutually.

Overall package of the present utility model and seeding characteristics:

Main shaft (11) two ends are equipped with pull bar (12) and are locked on the axle with bolt.Main shaft (11) middle part dress seeds discharging box, seeding wheel disc.It is fastening with screw and main shaft that the seeds discharging box left end connects dish (22), and hide in the seeding rotating disk ring cavity its box chamber, makes the box chamber left end gear teeth (18) be meshed with moving tooth post on the moving tooth circle (8).The seeding rotating disk can be gone up rotation flexibly, stable drive at main shaft (11).

During sowing, to flow to seeds discharging box indoor through revealing son tube (24) for seed in the warehouse, seeder is travelled by the extension bar traction at random, the seeding rotating disk rolls forward along the mulch film surface, moving tooth circle (8) drives plectrum wheel (21) and rotates, by the hemispherical depression on the plectrum wheel (21) a brood of seed, transfer to the box chamber, unnecessary is brushed by hairbrush, and seed is at centrifugal force, enters funnel (6) under the action of gravity and slips in the duckbilled (1), when this moment, the seeding rotating disk made duckbilled (1) be pressed into hole-ground film to bury that circular flat is close to mulch film on making the duckbilled tongue with self gravitation, spring (10) is compressed, and the duckbilled tongue opens automatically, and a brood of seed is entered in the cave.When duckbilled (1) goes out from the cave axis gradually be, duckbilled tongue (2) is closed automatically because of being subjected to the spring force effect, plectrum wheel (21) has rotational synchronization with the seeding rotating disk, turn to consistent and by certain rotating ratio transmission, thereby the plectrum wheel can be aimed at duckbilled and makes quantitatively to discharge seed.
