Five, embodiment

Below in conjunction with accompanying drawing structure of the present utility model is done concrete detailed description the in detail:

By Fig. 1, shown in Figure 2, the utility model is that frame 3 front upper parts are equipped with internal combustion engine 1, there is the fuel tank 23 that is connected with the carburetor of internal combustion engine 1 middle and upper part, left handle 16 and right handle 29 are equipped with in frame 3 upper backs, the gear shift arm of internal combustion engine 1 links to each other through the gear changing by foot arm 14 of pull bar 13 with frame 3 rear portions, on the right handle 29 internal-combustion engine ignition switch 30 is housed, with throttle control hand lever 31, respectively with internal combustion engine on igniter link to each other with carburetor, a left side is equipped with main clutch handle 15 on the handle 16 and is linked to each other with clutch on the internal combustion engine 1, start arm 26 is arranged on the internal combustion engine, multi-functional dispenser is equipped with in frame 3 upper backs, seed-box 22 is arranged at its top, two road wheels 4 are equipped with through live axle in frame 3 bottoms, frame 3 rear lowers have the grain tube 7 that is connected with the seeding unit 21 of multi-functional dispenser, plough 8 and drawbar formula covering device 9, plough 8 is linked to each other with drawbar formula covering device 9 by endless chain, sprocket wheel 28 on the axle 11 of press wheel 10 links to each other with the sprocket wheel on the feed shaft 19 33 through chain, sprocket wheel 2 on the internal combustion engine 1 links to each other with jackshaft 25 upper sprocket wheels 24 through chain, sprocket wheel 27 on the jackshaft 25 is linked to each other with sprocket wheel 5 on the live axle 6 by chain, and suppression wheel shaft 11 is below support arm 12 is contained in frame 3 rear portions; Said multi-functional dispenser be below seed-box 22 seeding unit 21, seed wheel 20, feed shaft 19, connect take turns 33, plate 18, grain tube 7, adjusted plate 17 and stir pin sleeve 32 and constitute, seed wheel 20 in the seeding unit 21 is contained on the feed shaft 19, be equipped with on the feed shaft 19 of seeding unit 21 outsides and stir pin sleeve 32 and sprocket wheel 33, on seeding unit 21 lateral walls below the seed-box 22 adjusted plate 17 and plate 18 are housed, grain tube 7 is contained in seeding unit 21 bottoms, grain tube 7 bottoms dress plough 8.

Multi-functional dispenser is a core apparatus of the present utility model, in the use, according to seed grain size and requirement, adjusted plate 17 and stir pin sleeve 32 makes seed wheel 20 left and right displacement that are contained on the feed shaft 19, select to use seeding modes different above the multi-functional seed wheel 20 and suitable seeding quantity, the sowing port that is not used covers with plate 18, and it can broadcast chemical fertilizer, a tractor serves several purposes with executing as the seed of sowing Different Crop, very convenient, the efficient height.It is to contact the frictional force that is produced with ground by press wheel 10 to make the sprocket wheel 33 on the feed shaft 19 drive coaxial seed wheel 20 rotations (interlock) by the sprocket wheel 28 on the suppression wheel shaft 11 through chain that the arbor wheel of seeder 20 rotates, the adjustment of the suppression of press wheel 10 and sowing depth after planting is by regulating (support arm 12 can adopt U-bolt to be contained on the frame) that the link position of support arm 12 on frame 3 realized, press wheel with make sower walking linearity good being connected of frame, guarantee that amount of seed metering is reliably even.The change of operating speed be by main clutch handle 15 through brake cable link to each other with clutch on the internal combustion engine with frame 3 on gear changing by foot arm 14 link to each other with gear shift arm on the internal combustion engine by pull bar 13 and realize that the change of its line-spacing is by regulating (can adopt U-bolt that plough is contained on the frame) that the link position of plough 8 on frame 3 realized.

By above-mentioned situation as can be seen, the utility model is that frame is a carrier, with the internal combustion engine is that power drive is advanced, and once can finish the multi-mode operation such as trench digging, sowing, earthing, suppression of multiple kinds of crops, easy to operate, easy to use, the deep placement that also can be used for granulo-fertilizer, the business efficiency height improves work efficiency 5-7 doubly than existing people's animal power sower, alleviated labour intensity greatly, it is applied and must make creative contribution for the high yield good harvest that improves agricultural mechanization and agricultural.
