When sowing, left hand holds the back bar manipulation sowing of steering handrail, the direction of advance driven forward of fertilizer applicator is sowed, The plough point of fertilizer applicator, the two-sided mouldboard right end of mouldboard ploughshare ploughs soil, and the two-sided mouldboard of mouldboard ploughshare right end ploughs plough point The soil risen is overturn towards front and rear sides, and the lower end of ploughshare body is made to form a Tu Gou, and the right hand is lifted up discharging fork arm left end Throw rod, the drawstring bar for the fork arm bottom righthand side that discharges is by soft wirerope toward Zola, and soft wirerope is by the rectangle of apron block Internal cavity in baffle toward Zola, make the circle discharge port of baffle right end toward moving left, make the circle discharge port and gear of baffle right end The lower round tube hole of the seat bottom plate left end of panel seat and the circular hole of interior empty lower end of storage hopper and the upper round tube hole of cover board left end communicate, Seed in the interior sky of storage hopper under the effect of gravity along the circular hole of the interior empty lower end of storage hopper, cover board left end it is upper Round tube hole, the circle discharge port of baffle right end, the lower round tube hole of the seat bottom plate left end of apron block, the circle material transport hole B of delivery pipe, lifting The circle material transport hole A of trussed beam, the open recess of the lower end round tube hole A and round tube hole A of ploughshare body upper end drop in the native ditch plowed, The sowing of driven forward, fertilizer applicator lifting trussed beam lower part left end splayed configuration soil returning plate by two-sided mouldboard towards front and rear sides The soil of overturning covers back in the native ditch plowed, and seed is embedded in soil.The electronic digging cave of the utility model collection, manual sowing, electricity Dynamic covering soil is completed at the same time the synthetic job of sowing in one, when sowing easily, easily and fast, it is strong effectively to mitigate labour It spends, significantly improve working efficiency.

The throw rod of control discharging fork arm left end is lifted up height, just can control the circle discharge port and lid of baffle right end The connection area of the upper round tube hole of plate left end just can control the amount of falling of seed, control application rate.

The throw rod for being lifted up discharging fork arm left end is not put, and can be connected during sowing, fertilizer applicator driven forward Continued broadcasting kind.

The throw rod for the discharging fork arm left end being lifted up is decontroled, the baffle in the rectangular internal cavity of apron block is being drawn The elastic force effect for stretching spring is lower toward moving right resets, and the left end of baffle is by the circular hole of the interior sky lower end of storage hopper and cover board left end Upper round tube hole seal, seed can not be fallen, can stop sowing.

The intermittent throw rod for being lifted up discharging fork arm left end just can be carried out fixed point sowing.

When big field is to planting neat crop line by line and applying granulo-fertilizer, with the operating method energy of above-mentioned sowing Continuous fertilization is carried out, stops fertilising and applies fertilizer to every clump of crop fixed-point.

The benificial effect of the utility model is to the utility model is due to using the above structure, collecting electronic digging cave, manual sowing Or fertilising, electronic covering soil is in one, when being completed at the same time the synthetic job of sowing or fertilising, sowing or fertilising easily, conveniently, Quickly, it effectively reduces labor intensity, significantly improve working efficiency.

Due to being slowed down using double shaft worm reduction gears, the reduction ratio of double shaft worm reduction gears is big, can reduce It sows, the volume and weight of fertilizer applicator, electric energy can be saved, reduce production cost.

Due to being slowed down using double shaft worm reduction gears, double shaft worm reduction gears have self-locking function, work as direct current When motor is slack, double shaft worm reduction gears self-locking can steadily be braked, and not need that braking mechanism is in addition arranged again, Noise when braking mechanism brake is eliminated, the production cost of braking mechanism is saved, reduces the occupied space of braking mechanism.

Due to slowing down using double shaft worm reduction gears, it is separately mounted to forward and backward the two of double shaft worm reduction gears The forward and backward symmetrical chain conveyer of the driven sprocket of the front and rear ends of drive sprocket and hind axle on the projecting shaft at end, uniform force, Stable drive effectively improves the service performance of sowing, fertilizer applicator.
