Embodiment
Be described in detail of the present invention below in conjunction with drawings and Examples, accompanying drawing is take two anti-blocking unit of wheel drive, a ground as example.
The present invention includes as shown in Figure 1 and Figure 2: frame 1, spade jockey 2, anti-blocking unit, transmission system, asymmetric ditching device 5;
Anti-blocking unit of the present invention is fixed on the frame 1 through spade jockey 2; The U-shaped card 803 of anti-blocking speed change gear 8 usefulness of transmission system is fixed on the frame 1, and the power that land axle 9 is provided outputs to bevel gear tooth system 7, and head roll 4 rotates uprooting weed in horizontal plane; Asymmetric ditching device 5 is positioned at the lower end of spade 3, is that seed opener is ditched in advance in ditching-fertilizing.
Anti-blocking unit is is as shown in Figure 4 connected and composed through cylinder adapter sleeve 401 and bearing 402 by spade 3 and cylinder 4, cylinder 4 is welded on a hollow circular-tube by some hyperbolic-type spring steel poles interval and consists of on week, cylinder 4 upper ends and driven wheel of differential 703 are screwed, lower end inner sleeve bearing 402 is connected with spade 3 by cylinder adapter sleeve 401.
In above-described embodiment, cylinder adapter sleeve 401 is square internally and round externally shapes, and the inner rectangular hole dimension is identical with spade 3 external dimensions, and outside diameter is identical with bearing bore diameter, and about in the of 4 two ends to be welded on respectively cylinder, which is provided with the shaft shoulder, are used for locating corresponding bearing.
Transmission system shown in Fig. 5～8 comprises anti-blocking speed change gear 8, bevel gear tooth system 7, universal-joint-pin type universal shaft joint 10, land wheel 6 etc., it is inboard that the fixing U-shaped card 802 of anti-blocking speed change frame 801 usefulness speed change framves on the anti-blocking speed change gear 8 is fixed in frame 1 front-axle beam, the power of land wheel 6 is delivered to six side's power transmission shafts 804 of anti-blocking speed change gear 8 through land axle 9, six side's power transmission shafts, 804 two ends are by cap bearring 803 location, all sprocket wheels all adopt screw to connect on it, the convenient position of sprocket wheel on axle of regulating, speed change cone pulley 805 is welded by the sprocket wheel of a plurality of different numbers of teeth, selects first the sprocket wheel of suitable gear to provide power for bevel gear tooth system 7 before the sowing;
In above-described embodiment, when anti-blocking element number during greater than the quantity of land wheel 6, need to connect with the gear shaft 706 that universal-joint-pin type universal shaft joint 10 will adjacent anti-blocking unit, realize one 2 anti-blocking unit of wheel drive; Two continuous anti-blocking unit in operation process, will plant with on stalk be allocated between the two, for guaranteeing the uniformity of sowing line-spacing, need planter is arranged at the outside of spade, in 5 liang of side guard plates of asymmetric ditching device the drift angle large with the planter homonymy, namely two spades distances is that 1 line-spacing deducts 2 seed manure spacings;
Operation principle of the present invention is, when the seeding operation of stalk ground, tractor drives land wheel 6 and advances, land wheel 6 through land axles 9 and on the sprocket wheel chain give anti-blocking speed change gear 8 with transmission of power, select in advance suitable sprocket wheel in the speed change cone pulley 805 on the anti-blocking speed change gear 8, power outputs on the drive sprocket 1001 of universal-joint-pin type universal shaft joint 10, jackshaft 1003 connects two half a couplers 1002, the gear shaft 706 of universal-joint-pin type universal shaft joint 10 left and right sides is the bevel gear tooth system input power, be that drive bevel gear 705 drives driven wheel of differential 703 rotations, because the commutation function of bevel gear, the interior rotation of land wheel perpendicular this moment has been converted to the rotation in driven wheel of differential 703 horizontal planes; Cylinder 4 is screwed with driven wheel of differential 703, therefore the direction of motion of the two is identical with speed, and cylinder 4 and spade 3 are connected with bearing by cylinder adapter sleeve 401 and are connected, spade 3 relative frames 1 are static in the seeding operation, and cylinder 4 rotates in horizontal plane relative to frame 1, and the cylinder 4 of rotation dials the place ahead stalk from kind of a band; When agriculture requirement corn seeding side deep fertilizing, seed opener is positioned at the right side of asymmetric ditching device 5, just can ditch in advance for seed opener in the time of ditching-fertilizing, the situation of avoiding the seed opener such as two disks to be difficult for burying.
The various embodiments described above only are used for explanation the present invention, and wherein the structure of each parts, connected mode etc. all can change to some extent, and every equivalents and improvement of carrying out on the basis of technical solution of the present invention all should do not got rid of outside protection scope of the present invention.
