The utility model discloses a use method as follows:
before using underground fertilizer applicator, can be earlier connected feed connector 8 with the fertilizer can that stores fertilizer through the pipeline, and external screw thread 801 on the outer wall of feed connector 8 tip does benefit to the connection between self and the pipeline tip, and meanwhile, fertilizer in the fertilizer jar of bearing on one's body then can directly enter into feed connector 8 along the pipeline in, then enters into feeding chamber 64, finally is full of feeding chamber 64.
Before fertilization, the fertilizing amount can be adjusted according to actual needs, when the fertilizing amount needs to be adjusted, the fastening nut 21 can be rotated, so that the fastening nut 21 is not pressed on the bottom of the sliding groove 17, after the limitation of the fastening nut 21 is lost, the quantitative inner cylinder 66 is not fixed with the quantitative outer cylinder 63, the quantitative inner cylinder 66 can move outwards along the positioning screw 20, the sliding hole 19 and the sliding groove 17 are both in a strip shape, therefore, the movement of the quantitative inner cylinder 66 cannot be limited due to the existence of the positioning screw 20, the outer wall of the quantitative inner cylinder 66 is not completely attached to the inner wall of the quantitative outer cylinder 63 along with the gradual movement of the quantitative inner cylinder 66 out of the quantitative outer cylinder 63, at the moment, the part of the material passing hole 67 at the position where the two parts are not attached to each other is not covered and blocked by the outer wall of the quantitative inner cylinder 66, meanwhile, the front end surface of the quantitative inner cylinder 66 and the inner wall of the quantitative outer cylinder 63 enclose to form a space communicated with the material passing hole 67, when the space is sized, can store quantitative fertilizer, and when this space size of need design, only need stop to remove ration inner tube 66, screw fastening nut 21 on the bottom of spout 17 groove once more, under fastening nut 21's fastening effect, the position of ration inner tube 66 obtains fixedly, and the fertilizer that lies in feeding chamber 64 originally then can get into fast under the action of gravity to the ration inner tube 66 front end terminal surface and the ration urceolus 63 inner wall enclose the space that closes and form in, finally is full of this space.
When the space formed by the front end surface of the quantitative inner cylinder 66 and the inner wall of the quantitative outer cylinder 63 is filled with fertilizer, the fertilization work can be started, a fertilizer applicator can hold the holding handle 2 to enable the underground fertilizer applicator to be in a vertical state, the lower end of the fertilizer application pipe 10 faces downwards, the holding handle 2 faces upwards, then the downward end of the fertilizer application pipe 10 can be inserted into the ground through the holding handle 2, the lower end of the fertilizer application pipe 10 is of a shovel type, so that the fertilizer applicator can be easily inserted into soil and deeply enter the ground, the underground fertilization work can be conveniently developed, when the shovel-shaped end of the fertilizer application pipe 10 is inserted into the ground, a hand holding the holding handle 2 can pull the pull handle 3 upwards, along with the upward movement of the pull handle 3, the pull handle 3 drives the connecting arm 47 to move upwards through the guide rod 6, the upper end of the second traction steel wire 13 is connected to the fifth connecting hole 48 on the connecting arm 47, and when the pull handle 3 moves upwards, the lower end of the second traction wire 13 is fixed on the swing arm 16, when the second traction wire 13 is pulled upwards, the second traction wire 13 pulls the swing arm 16 upwards, at this time, the swing arm 16 rotates anticlockwise around the hinge shaft 31, the tension spring 36 is stretched and generates elasticity, the square clamp hole 30 on the swing arm 16 is clamped with the square clamp 27 on the front end face of the quantitative outer cylinder 63, and the rotating swing arm 16 drives the quantitative outer cylinder 63 to rotate anticlockwise along the track of the arc-shaped groove 62 through the square clamp 27.
When the quantitative outer cylinder 63 rotates counterclockwise, the fertilizer in the space formed by the enclosing of the inner wall of the quantitative outer cylinder 63 and the front end face of the quantitative inner cylinder 66 also rotates, the upward material passing opening 67 starts to face downward along with the rotation, at this time, the quantitative outer cylinder 63 prevents the fertilizer in the material feeding cavity 64 from falling through the outer wall of the quantitative outer cylinder 63, the space formed by enclosing of the inner wall of the quantitative outer cylinder 63 and the front end face of the quantitative inner cylinder 66 is communicated with the material discharging cavity 65 through the material passing opening 67, the fertilizer in the space formed by enclosing of the inner wall of the quantitative outer cylinder 63 and the front end face of the quantitative inner cylinder 66 directly falls into the material discharging cavity 65 under the action of gravity, and then falls into the fertilizer applying pipe 10 connected with the material discharging joint 9 and finally falls to the lower end of the fertilizer applying pipe 10, when the swing arm 16 rotates counterclockwise, the swing arm 16 pulls the first pulling steel wire 12 upward, at this moment, the first pulling steel wire 12 pulls the hook-shaped portion 44 upward through the lower end 46 of the first pulling steel wire, the sealing cover 11 rotates and swings with the limiting screw rod 41 as the center, the sealing cover 11 no longer covers the lower end pipe orifice of the sealing fertilizing pipe 10, the pressing part 4301 of the torsion spring 43 presses the right outer wall of the fertilizing pipe 10, and the end parts 4302 at the two ends of the torsion spring 43 press the right side wall of the sealing cover 11, so that when the sealing cover 11 rotates and swings, the torsion spring 43 is pressed to generate elastic force, when the lower end pipe orifice of the fertilizing pipe 10 is in an open state, fertilizer falling into the fertilizing pipe 10 finally enters the ground through the lower end pipe orifice of the fertilizing pipe 10, and the effect of underground fertilization is achieved.
After fertilization is finished, only the lower end of the fertilization pipe 10 is pulled out of the ground and the pull handle 3 is loosened, at the moment, the tension spring 36 can pull the swing arm 16 to reset through self elasticity, meanwhile, the torsion spring 43 can reset the sealing cover 11 through self elasticity to plug and seal the pipe orifice at the lower end of the fertilization pipe 10 again, when the sealing cover 11 resets, the traction plate 44 on the sealing cover 11 can pull the swing arm 16 to reset through the first traction steel wire 12 to play a role in auxiliary resetting, when the swing arm 16 resets, the swing arm 16 can pull the guide rod 6 through the second traction steel wire 13 to reset the pull handle 3, at the moment, the quantitative outer cylinder 63 synchronously resets, the material passing hole 67 on the quantitative outer cylinder 63 is communicated with the material feeding cavity 64 again, fertilizer in the material feeding cavity 64 enters the space formed by the inner wall of the quantitative outer cylinder 63 and the front end face of the quantitative inner cylinder 66 through the material passing hole 67 again and is filled with the space, because the space size is not changed, when the underground fertilizer applicator applies fertilizer again, the fertilizer application amount is equal to the previous fertilizer application amount once, thus ensuring the quantitative fertilizer application effect.
