Embodiment
Below in conjunction with accompanying drawing the utility model is described further.As shown in Figure 1 and Figure 2, a kind of seedling cultivation of rice drag links, comprise sprocket wheel, wheel shaft, crank handle, earthing roller assembly, casing, support, road wheel, it is characterized in that being equipped with on the hand sprocket shaft 2 power chain 1 and be installed in support 15 tops by a bearing and a watt seat, crank handle 3 is installed on the hand sprocket shaft 2 by nut, and support 15 bottoms are fixed on the upper left place of casing 14 end plates with screw; Four road wheels 18 are installed in the bottom of casing 14 two ends end plates by live axle 12, road wheel semiaxis 19 and bearing, watt seat, and sprocket wheel 11 is installed in the two ends of live axle 12, finishes four-wheel and supports walking states; Earthing roller chain 7 is equipped with at earthing roller assembly 9 two ends, and is fastening with key and big nut 8, is fixed on casing 14 lower openings places by bearing 13, watt seat 6; Power chain 1 is connected with the sprocket wheel 10 of live axle 12 by chain 4, and earthing roller chain 7 is connected with two sprocket wheels 11 of live axle 12 by chain 17.
As Fig. 3, shown in Figure 4, main innovate point of the present utility model is that casing mechanism is compared with existing structure and has done bigger improvement, the new casing mechanism that earthing roller assembly 9 adopts for the utility model, wherein, Fig. 3 grizzly bar of dismantling is represented earthing roller assembly mounted inside relation: earthing roller assembly 9 is by several expansion tooth plate 91, hollow shaft head bracing ring 92, eccentric shaft 93, flexible tooth plate connecting bushing 94, grizzly bar 95 is formed, earthing roller chain 7 is installed at hollow shaft head bracing ring 92 places, by bearing 13, bearing shell 6 is fixed on the two ends end plate of casing 14, eccentric shaft 93 passes from hollow shaft head bracing ring 92, by crossing bridge bracket 5, bearing, watt seat is fixed on the two ends end plate of casing 14, flexible tooth plate 91 is connected with eccentric shaft 93 by flexible tooth plate connecting bushing 94, rotate mutually between cover and the axle, the two ends of grizzly bar 95 are fixed on the hollow shaft head bracing ring 92 by screw, make it to become rigid unitary, a flexible tooth plate 91 is set between per two grizzly bars 95, be matched in clearance.Power crank handle 3 is rotated, drive sprocket wheel 1 and rotate, drive sprocket wheel 10,11 by chain 4 and rotate, drive earthing roller chain 7 and hollow shaft head bracing ring 92 and grizzly bar 95 by chain 17 and rotate, flexible tooth plate 91 promotes by grizzly bar 95, also rotates around eccentric shaft 93 together thereupon.
The utility model when operation, hold handrail handle 16 on the other hand, another is hand starts to shake crank 3, and power chain 1 is rotated, and by chain 4, sprocket wheel 10 live axle 12 is rotated, thereby drives road wheel 18 and rotate, and drag links move ahead; Driving earthing roller assembly 9 simultaneously rotates, soil is released in the case by flexible tooth plate 91, most of soil free falling this moment, when being rotated further, the part high humidity sticks on the soil on the flexible tooth plate 91, when the slit 2-3mm of tooth plate 91 by 95 of two grizzly bars that stretch constantly bounces back to low spot it is wiped off, row, scraping stroke finish, thereby finish the earthing operation at this moment.
Figure 5 shows that the operation principle of earthing roller: power drives hollow shaft head bracing ring 92 by power chain 1 and grizzly bar 95 rotates, and flexible tooth plate 91 promotes by grizzly bar 95, also rotates around eccentric shaft 93 together thereupon; When flexible tooth plate 91 during at the B point, highly be zero, continue when the A direction is rotated, the height of flexible tooth plate 91 increases in native case gradually, constantly stretches in the soil, and promotes soil before the tooth plate to the motion of A direction, when arriving the A point, pushes away the earth stroke end of fetching earth from native case; When being rotated further, soil is released in the case by flexible tooth plate 91, most of soil free falling this moment, when reaching maximum tooth depth C point and be rotated further, the part high humidity sticks on the soil on the flexible tooth plate 91, when the slit 2-3mm of tooth plate 91 by 95 of two grizzly bars that stretch constantly bounces back it is wiped off, row, scraping stroke finish during to the B point.
In the utility model, the grizzly bar material can be a metal or nonmetal; The grizzly bar cross section can be solid or hollow trapezoidal, triangle, fan-shaped, arc, annular, " T " font, " Off " font; The material of bracing ring can be a metal or nonmetal, and its shape changes along with grizzly bar section configuration difference; The quantity of flexible tooth plate is some, determines that according to the diameter of earthing roller and the version of grizzly bar quantity is many more, and its thickness of earth covering is even more, and heaving of the sea is more little; When grizzly bar length was big, the centre should add bracing ring, to increase axial counter-bending ability.In the present embodiment, " Off " font is adopted in the grizzly bar cross section, can reduce the weight of equipment so significantly, makes things convenient for the field to shift.
