Embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6.The embodiment of the utility model is a kind of mechanical external regulation type precision drill, and it comprises indenting tool assembly (26), rolling disc (27), end cap (28), adds kind of a mouth (29), bolster (31).The utility model is set at both ends of the support plate between the cover (12) is a non-rotating, can be cast aluminum or high-quality nylon, the center is divided into two divisions into its cavity, the cavity of the left chamber of the upper left (19) with a support plate bone ribs (18) spaced from the lower left portion of the drive chamber (11); right chamber of the seed distribution chamber (17), there are barrier ribs; the drive chamber (11) installed in the driving gear (8 ) through the inner sleeve (7) Set in a rotating disk (27) opposite the rotating main plate, nylon inner liner materials available, while the system out of one end of the gear ratio of the gear tooth root diameter slightly smaller round table in the round table on the outer cylinder to open a gap, so that only a single direction of rotation of the spine to allow the hook (10) hook into it, ratchet hook (10) of the tail of a hole in the support package pin (9), and ratchet hooks (10) can be rotated about the support pin (9) rotated, the support pin (9) fixed to the rotating plate (27) opposite the rotation of the master disk, the rotation of the master disk drive support pin (9) is transferred, the ratchet hooks (10) hook the head of the drive gear (8) is transferred, when the planter backwards, turning the main disk reversal ratchet hooks (10) of the head surface slip Dou, not push the pinion gear (8) anti- turn, ensure minutes agencies stop rotating; pinion gear (8) engages backward gear (3), backward gear (3) sets? mounted on the central support shaft (4), the center support shaft (4) fixed to the support plate (12), and does not rotate; backward gear (3) simultaneously engages minute drive gear (1) and a barrier brush driving gear wheel (6), minute drive gear (1) and the distribution chamber located in the seed ( 17) of the minute wheel (16) with a central axis of the (2) supported by nylon bushing supported on the intermediate support plate (12), they are the same number of revolutions and steering; barrier brush driving gear wheel (6) and located in the seed distribution chamber (17) of the blocking wheel brush (22) by a round brush with a central axis of the barrier (5) supported by the intermediate nylon sleeve is supported on the support plate (12), they are the same as the number of revolutions and steering, The difference is that the barrier brush driving gear wheel (6) less the number of teeth (12 teeth), minute drive gear (1) of the number of teeth (26 teeth), and thus minute wheel (16) the number of revolutions is low, the barrier wheel brush (22) the high number of revolutions; minutes wheel (16) of the cylindrical recess is provided with seeds (15) and minutes wheel (16) arranged outside the cylinder block wheel brush (22) of the outer and It is tangent to the direction of rotation are two identical; the minute wheel (16) of the bottom left of the kind set up a care brushes (23) fixed to the support plate (12) does not rotate, it extends the length of the arc kinds of wheels (16) of the species under the opening (24) at the main role is said to be held onto the block or on request from the kind of seed openings (24) top row down, this a kind of openings (24) are located in a hole assembly (26) outside the circle of care kind of spoon (25) upper cavitation assembly (26) into the hole on a fixed multiple devices monomer (20), into the hole assembly (26) of the inner and outer There are several types of care between turns spoon (25), the line into a circle shipped kinds orbit.Indenting tool assembly (26) is a prior art, and the mechanism of novel just that its is the inner distribution seed of this reality designs again.Set up except that card type device (13) in the below of seed distributing wheel (16); Its medial surface is processed the partial arc shape; It directly extend in the bottom of seed recess (15), and the seed that can will be stuck in sometimes in the seed recess (15) shovels, and its afterbody is fixed by bolts on the supporting disk (12).Set up on the upper left side that stops wheel brush (22) and to have cleaned device (21) with water and also reach between the bristle that stops in the wheel brush (22) certain depth to remove card type, it also is that afterbody is fixed by bolts on the supporting disk (12).
As above said a kind of mechanical external regulation type precision drill; The structure of the seed distributing wheel of in seed distributing chamber (17), installing (16) is that the six side's main shafts (32) (this axle promptly is seed distributing wheel central shaft (2)) at the center are equipped with the axial location that locking plate (33) limits seed distributing wheel (16) at the diagram right-hand member of axle; Diagram left end at axle installs and fixes the axial location that pin (40) also limits seed distributing wheel (16); Surely enclose (38) diagram right side at seed distributing wheel and be set with seed distributing wheel moving-coil (37); It encloses (38) surely with seed distributing wheel and forms seed recess (15) jointly; Seed distributing wheel moving-coil (37) and seed distributing wheel enclose (38) surely has synchronous turning to and revolution, and different just seed distributing wheel moving-coils (37) can be adjusted change at the axial location of seed distributing wheel wheel (16), and seed distributing wheel encloses the axial location of (38) surely and fixes; Adjustment seed distributing wheel moving-coil (37) is accomplished by adjustment screw (34) and compression spring (39) in the axial position of seed distributing wheel (16) jointly; When rotating adjustment screw (34), make the six sides adjustment nuts (36) of embedding casting in seed distributing wheel moving-coil (37) that is to say seed distributing wheel moving-coil (37) move left and right, thereby change the volume size of seed recess in the axial move left and right of seed distributing wheel (16); The interior side outer ring lining (35) of the last suit of six side's main shafts (32) and six side's main shafts (32) and seed distributing wheel moving-coil (37) rotate together.
Seed recess concrete structure is to be that the centre-to-centre spacing of every adjacent seed recess (15) is identical at circumferencial direction, and centre-to-centre spacing size numerical value has multiple by the planting technology decision; The geometry of seed recess (15) is the elliptical horn shape, and horn-like is inner small and outside big, and promptly the radially inner side base diameter is little, and the radial outside diameter is big, and size numerical value is multiple model by the size decision of seed; The seed recess is all cut the groove of 1.5mm～2mm at the circumferencial direction of the bottom of seed recess (15), the degree of depth is in the recess bottom, and seed distributing wheel (16) is processed with casting technology, and material application nylon 101 in village's is for well.Install in the groove to remove card type device (13) material be the high duty alloy plate.
The adjustment seeding quantity promptly is the volume size that changes the seed recess; The adjustment operation is to carry out in the outside of indenting tool assembly (26), does not promptly take indenting tool assembly (26) apart, only needs outside end face, to adjust its adjustment screw (34) and gets final product.
The utility model machinery external regulation type precision drill course of work is that seed adds from adding kind of a mouth (29); After distributing, the seed sorting mechanism of seed in seed distributing chamber (17) discharge entering holder kind of spoon (25) from going out kind of an opening (24); Because holder kind of a spoon (25) is a plurality of; It is identical with the kind nest number that divides seed to take turns on (16), and each seed of planting nest all gets into each corresponding holder kind spoon, and is transported to completion seeding operation in the relative another side entering indenting tool monomer (20) along with the indenting tool assembly rotates seed.
The utility model machinery external regulation type precision drill assembly by end cap (28) be fixed on a bolster that does not rotate (31) upper support, bolster is fixed on again on the frame of the machine of broadcasting.
