The fertilizer spreading machine
Technical field
The utility model belongs to agricultural machinery, relates in particular to a kind of fertilizer spreading machine.
Background technology
Along with expanding economy, in agricultural production, the use of agricultural machinery is more and more, such as sower, combine etc., but, but lack machinery easy and simple to handle, dependable performance in this link of fertilising, in the time of autumn planting, basically by artificial fertilizer spreading, take a lot of work effort and inefficiency.
Summary of the invention
The purpose of this utility model provide a kind of broadcast sowing scope wide, save the fertilizer spreading machine of manpower, high efficiency.
For achieving the above object, the utility model adopts following technical scheme: a kind of fertilizer spreading machine, comprise frame, upper rack is equipped with hopper, feed opening is arranged at the hopper bottom, and power transmission shaft is housed on the frame, and belt pulley is housed on the power transmission shaft, the power transmission shaft other end is equipped with accelerator, impeller is housed on the accelerator shaft, a support plate is arranged on the frame, the accelerator lower housing portion links to each other with support plate, impeller upper plate and impeller lower plate are housed on the accelerator housing, impeller is equipped with arcuate fixed baffle plate and sideboard on the impeller lower plate between impeller upper plate and impeller lower plate, the refining mouth is arranged on the impeller upper plate, the refining mouth is positioned at the feed opening below, and discharge flapper is arranged on the feed opening.
Power transmission shaft one end is equipped with driving wheel, and shaft is housed in the hopper, and agitating plate is housed on the shaft, and shaft one end is equipped with follower, and driving wheel links to each other by belt in use with follower.
Discharge flapper links to each other with a pull bar, is set with spring on the pull bar, and the pull bar other end is equipped with backguy.
The accelerator lower housing portion has positioning screw, and arc positioning groove is arranged on the support plate, and positioning screw passes locating slot, and setscrew nut is housed on the positioning screw.
Adopt the fertilizer spreading machine of technique scheme, can be contained on the tractor, move ahead with tractor, and utilize the power of tractor to drive the impeller rotation, the fertilizer that will fall from hopper is sprinkling upon in the field equably, broadcast sowing scope 5-6 rice, one man operation gets final product, and can spread 200-300 mu every day, has saved manpower greatly, high efficiency has improved autumn planting speed.

Embodiment
Fertilizer spreading machine as shown in Figure 1, comprise frame 1, hopper 12 is equipped with on frame 1 top, and feed opening 10 is arranged at hopper 12 bottoms, and power transmission shaft 20 is housed on the frame 1, belt pulley 19 is housed on the power transmission shaft 20, power transmission shaft 19 1 ends are equipped with driving wheel 21, and shaft 13 is housed on the hopper 12, and agitating plate 11 is housed on the shaft 13, shaft 13 1 ends are equipped with follower 14, and driving wheel 21 links to each other by belt in use with follower 14.Power transmission shaft 20 other ends are equipped with accelerator 2, and impeller 5 is housed on the accelerator shaft 3, as shown in Figure 2, fertilizer-shaking claw 51 are housed on the impeller.One support plate 23 is arranged on the frame 1, and accelerator 2 lower housing portion have positioning screw 24, on the support plate 23 arc positioning groove are arranged, and positioning screw 24 passes locating slot, and setscrew nut 22 is housed on the positioning screw 24.Impeller upper plate 6 and impeller lower plate 4 are housed on accelerator 2 housings, impeller 5 is between impeller upper plate 6 and impeller lower plate 5, arcuate fixed baffle plate 17 and sideboard 7 are housed on the impeller lower plate 4, refining mouth 8 is arranged on the impeller upper plate 6, refining mouth 8 is positioned at feed opening 10 belows, and discharge flapper 9 is arranged on the feed opening 10, and discharge flapper 9 links to each other with a pull bar 16, be set with spring 15 on the pull bar 16, pull bar 16 other ends are equipped with backguy 18.
The effect of sideboard 7 is fabric widths of regulating broadcast application.Positioning screw 24 on the accelerator 2 can move in the locating slot on the support plate 23, serves as that axle rotates an angle thereby make accelerator 2 with power transmission shaft 20, and then makes impeller 5 that a gradient be arranged, the final distance that throws away chemical fertilizer of regulating.
The utility model in use, frame is equipped with on the tractor, driving belt pulley 19 by engine rotates, drive shaft 13 and start working, stir the chemical fertilizer in the hopper 12, impeller 5 is rotated by accelerator, the people spurs backguy 18 on tractor, discharge flapper 9 is removed, and chemical fertilizer begins to fall, and the chemical fertilizer that gets off throws away under the impeller effect.
