Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As Figure 1-4, drum-type vegetable seeds bunch planting seed placing device of the present invention, comprises switch 1, frame 2, elevating hopper 3, seeding unit 4, hairbrush 5, rear walking wheel axle 6, wheel 7, hopper 8, freewheel clutch 9, first chain 10, first sprocket wheel 11, front walking wheel axle 12, motor 13, second sprocket wheel 14, the 3rd sprocket wheel 15, the 4th sprocket wheel 16 and the second chain 17; The below of the front and back end of described frame 2 is separately installed with front walking wheel axle 12 and rear walking wheel axle 6; Described front walking wheel axle 12 is all fixedly connected with wheel 7 with the two ends of rear walking wheel axle 6, and front walking wheel axle 12 is also fixedly connected with the first sprocket wheel 11; Described motor 13 is arranged on the side above frame 2 front end, and the output shaft of motor 13 is fixedly connected with the second sprocket wheel 14 and the 3rd sprocket wheel 15; 3rd sprocket wheel 15 is connected by the second chain 17 with the first sprocket wheel 11; In frame 2 front end, upper surface is provided with switch 1; Described switch 1 is connected with motor 13, controls the rotating speed of motor 13 and turns to; Described seeding unit 4 comprises planting cylinder 41, camshaft 42, push rod 43 and spring 44; Described planting cylinder 41 has the through hole of some evenly arrangements along the axial and circumferential directions; Through hole becomes stepped, and medial aperture is greater than aperture, outside; Elevating hopper 3 and hopper 8 is fixed respectively above and below described frame 2 rear end; Two side plate bottoms of described elevating hopper 3 and two side plate tops of hopper 8 all have arc-shaped breach; The breach of described elevating hopper 3 forms revolute pair with the breach of hopper 8 with planting cylinder 41 and is connected; Two side plates of elevating hopper 3 are fixedly connected with the fixed head that cross section is inverted L shape; The vertical side of described fixed head has circular hole, and one end of described planting cylinder 41 is fixedly connected with one end of freewheel clutch 9; One end of described camshaft 42 is fixedly connected with fixed head through the circular hole of fixed head, and the other end passes the through hole of freewheel clutch 9 successively and is fixedly connected with fixed head with the circular hole of fixed head; The other end of described freewheel clutch 9 is fixedly connected with the 4th sprocket wheel 16; 4th sprocket wheel 16 is connected by the first chain 10 with the second sprocket wheel 14; Between elevating hopper 3 and hopper 8, be provided with hairbrush 5, described hairbrush 5 is fixed on hopper 8, and hairbrush 5 has gentle touchdown with the planting cylinder 41 of seeding unit 4; Described hopper 8 has gathering sill, the notch of described gathering sill and the through hole one_to_one corresponding of planting cylinder 41 axis; The cam length of described camshaft 42 is identical with planting cylinder 41 length; Described push rod 43 is cylindrical bar, and top covers soft material, and bottom is hemispherical dome structure, is provided with the boss around push rod 43 near bottom; Described planting cylinder 41, camshaft 42, push rod 43 and spring 44 form cam mechanism.
As Figure 1-3, the output shaft of motor 13 is connected with front walking wheel axle 12 and seeding unit 4 with the second chain 17 respectively by the first chain 10, the planting speed of the speed of travel of seeding apparatus and seeding unit 4 can be made proportional all the time, and then make seed keep specific spacing in the rows all the time, and at seeding unit 4 power shaft place, freewheel clutch 9 is installed, realize seeding apparatus seeding unit in fallback procedures not work, be conducive to operations such as entering a new line, turn around; Hairbrush 5 keeps suitable with seeding unit 4 and contacts, and the seed not falling into seeding unit 4 aperture is stayed in elevating hopper 3 to keep the angle of 30o to 45o both to ensure with the horizontal plane of seeding apparatus, too large resistance is not produced to the rotary motion of seeding unit 4 simultaneously, achieve the control of the amount of seed under each work period is declined; There is gathering sill hopper 8 inside, with planting drum shaft to through hole have one-to-one relationship, both ensured that the line-spacing of the seed fallen is suitable, be unlikely to again to make seed in heaps, make it in order, carry out bunch planting uniformly.
As illustrated in figs. 5-7, motor 13 drives the planting cylinder 41 of seeding unit 4 to rotate by Chain conveyer, starting cam mechanism, the push rod 43 that rotarily drives of planting cylinder 41 moves, and camshaft 42 remains motionless, therefore reserve porose in the upper end of seeding unit 4, can stored seed, and seed is extruded seeding unit 4 by the motion of push rod 43 by the seed of its lower end, realizes planting, due to the effect of spring 44, push rod 43 can contact with camshaft 42 all the time; Structurally, push rod 43 upper end cover soft structures, avoid seed impact stress and cause damage, lower end is smooth structure, can with camshaft 42 smooth contact.
The course of work of the present invention is as follows:
Cave dish is put in sower front, vegetable seeds is poured into elevating hopper 3, starting switch 1, motor 13 entry into service, under chaindriven effect, sower advances along cave dish, seeding unit 4 works simultaneously, seed falls into the seed reserved opening above the planting cylinder 41 of seeding unit 4, along with the rotation of seeding unit 4, due to the running of cam mechanism, reserved opening on planting cylinder 41 is more and more less, when rotating to below, seed is ejected by the push rod 43 in seeding unit 4, fall into hopper 8, there is gathering sill in hopper 8, seed is made to constrain in gathering sill, cave dish is fallen into accurately along specific path, thus complete and once sow.
