Cam described in the above-mentioned technical solution can be two, the cam of three or more difform coaxial interlock, this moment, cam box 7 was provided with a spacing in the rows lever change 14 that connects with this cam, front end at push rod 22 is provided with a separation handle 18, by conversion and push rod 22 contacted cams, can realize the adjustment of spacing in the rows like this.
Discharging tube 13 lower ends in the above-mentioned technical solution can be provided with the even seed device 27 of a taper, and the seed that falls from discharging tube 13 during use disperses to sow to all around by the vertex of a cone effect of the even seed device 27 of taper, thereby reach the purpose of even seed.
The accompanying drawing drawing is described as follows:
Fig. 1 is the structural representation of an embodiment of this utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is the cross-sectional view of second embodiment of the utility model;
Fig. 5 is the cross-sectional view of the 3rd embodiment of the utility model.
Being described as follows of each label among the figure:
The 1-plough, 2-support, 3-draw bar, 4-kind case, the fertile case of 5-, the 6-handrail, 7-cam box, 8-land wheel, 9-press wheel, 10-trailing bar, the 11-breast boards, 12-defertilizing tube, 13-discharging tube, 14-spacing in the rows lever change, 15-camshaft, 16,17-cam, 18-separates handle, 19-seeding fertilizer plate, 20-pushing rod sleeve, the 21-spring, 22-push rod, 23-fertilizer hole, 24-feed outlet, 25-kind case, the 26-nut, seed device, 28-connecting rod are spared in the 27-taper.
Referring to Fig. 1, Fig. 2, Fig. 3 knows, this precise spot-sowing fertilizer distributor has a draw bar 3 and is arranged on the plough 1 of its lower end, the both sides of plough 1 are provided with a pair of breast boards 11, the rear end of breast boards 11 is equipped with a trailing bar 10 and press wheel 9 successively, support 2 is installed on the draw bar 3, this support is provided with a fertile case 5, a kind case 4 respectively is equipped with in fertile case both sides, case 4 and fertile case 5 corresponding discharging tube 13 and defertilizing tubes 12 are housed and plant in the lower end of support 2, the rear end of support 2 connects a cam box 7, the cam 16 and 17 of two coaxial rotation is housed in the cam box 7, cam 17 has three equally distributed projectioies, cam 16 has four equally distributed projectioies, cam box 7 is provided with a spacing in the rows lever change 14 that connects with cam, can adjust two cams 16 and 17 position in the axial direction by this handle, at the two ends of camshaft 15 land wheel 8 is housed respectively, push rod 22 is positioned at the pushing rod sleeve 20 of cam box 7 front ends, which is provided with a compression reseting spring 21, the front end of push rod 22 connects with rack-mount seeding fertilizer plate 19, this seeding fertilizer plate 19 can slide before and after the bottom of kind of case 4 and fertile case 5, which is provided with feed outlet 24 and fertilizer hole 23, at separation handle 18 that is installed on the pushing rod sleeve 20 of front end connection of push rod 22.
Know that referring to Fig. 4 these many kind casees 4 with the precise spot-sowing fertilizer distributor also can be provided with one as required, be arranged on the feed outlet 24 on the seeding fertilizer plate 21 like this and the discharging tube 13 that is installed on the support 2 also need be provided with one.
Know this uses the precise spot-sowing fertilizer distributor more referring to Fig. 5, also can as required fertile case be taken off and the kind case that changes the outfit that this example promptly is the structure after kind case of 5 usefulness of the fertile case among the embodiment 1 25 is changed, corresponding seeding fertilizer plate 19 also be should give replacing.In addition, the even seed device 27 of taper that an awl point makes progress can be set also in discharging tube 13 lower ends of this utility model, this even seed device can be installed on the discharging tube 13 by two connecting rods 28 and nut 26.
Pulling draw bar 3 during use, land wheel 8 promptly rolls forward, land wheel 8 drives cam 16,17 by camshaft 15 and rotates, wherein arbitrary cam promotes push rod 22 and does reciprocating linear motion, it is reciprocating that push rod 22 drives seeding fertilizer plate 19 again, seeding fertilizer plate 19 is done to stretch out and recoil movement on discharging tube 13 and defertilizing tube 12, makes it connect fertilizer when returning, and passes through feed outlet 24, discharging tube 13 and fertilizer hole 23, defertilizing tube 12 seeding fertilizers respectively when stretching out.When needing the conversion spacing in the rows, promote to separate handle 18 forward, push rod 22 is separated with cam,, thereby obtain two kinds of different spacing in the rows or be in neutral position again by pulling out or advance spacing in the rows lever change 14 to adjust cam position.
