Embodiment

Below in conjunction with accompanying drawing the utility model figure is described further.

Contrast Fig. 1, the front side of frame 2 is provided with three and tractor hitching axis M, N, I, fertile case 10 is contained in the top of frame 2, the two bottom sides of fertile case 10 be provided with two discharging openings 33,33 ', all be fan shape with install respectively in its outside, door 9,9 ' the bottom outside of its serrated end and fertile case 10 hinged, 9,9 ' can be respectively around separately pin joint A, A ' rotation, see also figure Fig. 5.Three transmission cases 5,14,5 ' parallel frame 2 middle parts that are installed in side by side, be equipped with three pairs of intermeshing bevel gears 2 in the case respectively, 6 and

bevel gear

15,13 and bevel gear 2 ', 6 ', about two transmission cases 5,5 ' in vertical drive shaft 7,7 ' the upper end connect broadcast application dish 8 respectively, 8 ', see also Fig. 2, at two broadcast application dishes 8,8 ' a radial position one centrifugal broadcast application plate 11 has been installed respectively, 11 ', at two broadcast application dishes 8,8 ' inboard top is respectively a discharging opening 33,33 ', door 9,9 ' open the fertile case 10 interior fertilizer in back just in time to drop on fertile dish 8,8 ' on, when broadcast application dish 8, during 8 ' rotation, fertilizer on it is under action of centrifugal force, along centrifugal broadcast application plate 11,11 ' tangential quilt shed away.At horizontal drive shaft 4,12,4 ' front end connect duplex chain wheel 26 respectively, 27,26 ', they lay respectively at

horizontal bevel gear

3,13,3 ' the front side, driving-chain 28 connects these three duplex chain wheels, the front end of middle horizontal bevel gear axle 12 connects universal connecting shaft 29, see also Fig. 3, power is passed to horizontal drive shaft 12 by universal connecting shaft 29, passing through driving-chain 28 and

duplex chain wheel

26,27,26 pass to horizontal drive shaft 4,4 ', again by

bevel gear

3,6 and

bevel gear

15,13 and bevel gear 3 ', 6 ' engagement, speed change, pass to

vertical drive shaft

7,16,7 ', the broadcast application dish 8 (8 ') and the knockout rod 30 that drive respectively on it rotate, because bevel gear 3,3 ' tapering of putting is opposite in axial institute, the bevel gear 6 that is engaged with, 6 ' switched in opposite, two broadcast application dishes 8 then, 8 ' switched in opposite, make it to shed to two side directions.Knockout rod 30 is long-pending built on stilts because of mutual extrusion or the higher knot of moisture content for preventing the fertilizer in the fertile case 10, is difficult for blanking setting, and it constantly hits, vibrates the fertilizer of fertile case bottom, and to make it to be difficult for long-pending piece built on stilts.
