The following will further explain the application method and the principle of the technical solution part in this embodiment with reference to the accompanying drawings:
firstly, loosen the height of nut 36 adjustment ear seat 30 according to the distribution of fruit tree root system earlier to realize the degree of depth of penetrating into soil of fertilization spade 28, spiral, shovel furrow opener in the past often causes the fruit tree root system to tear, and the wound is big, and difficult healing because the U-shaped structure that fertilization spade 28 and shovel wing 29 constitute in this embodiment, the shovel wing 29 of both sides can directly cut off the root, and the wound is little, and easy healing realizes the reasonable pruning of root system simultaneously. The rear fork-shaped structure is beneficial to entering soil and can dig a soil layer;
then an operator holds the handle 6 by hands, then steps on the ear seat 30 by two feet, and the fertilizing shovel 28 part is certainly partially inserted into soil, then the starting motor 2 drives the driving wheel 7 to rotate, and as the power output shaft end of the starting motor 2 is in eccentric butt joint with the driving wheel 7, the driving wheel 7 drives the control slide block 18 at the end part of the driving shaft rod 13 to do reciprocating swinging motion in the left-right direction by taking the second positioning seat 14 as the circle center through the positioning seat 9 and the positioning column 11 in the rotating process;
in the process that the control slide block 18 does reciprocating swing in the left-right direction, when the control slide block 18 runs to be closest to the upper end of the discharge pipe 26, the upper top surface of the control slide block 18 completely blocks the feeding pipe 20 to enable the feeding pipe 20 to be in a closed state, meanwhile, the positioning seat 9 and the positioning column 11 are also closest to the output shaft end of the starting motor 2, and the control bin 17 is also closest to the driving wheel 7;
when the control slide block 18 moves to the position which is farthest away from the upper end of the discharge pipe 26, the upper top surface of the control slide block 18 is not contacted with the feed pipe 20 any more, so that the feed pipe 20 is in an open state, at this time, fertilizer particles stored in the fertilizer box 5 can enter the feed pipe 21 through the discharge pipe 24, the rubber hose 25 and the feed pipe 20, the positioning seat 9 and the positioning column 11 are also at the end farthest away from the output shaft of the starting motor 2, the control cabin 17 is also at the farthest away from the driving wheel 7, the fertilizer application spade 28 is also completely inserted into the deep soil, at this time, the shaft roller 31 and the ear seat 30 are just tightly attached to the ground, the fertilizer application spade 28 starts to push the whole fertilizer application device outwards along the shaft roller 31 as a fulcrum during the downward insertion process (the fertilizer application spade 28 cannot be outwards along the posture after the fertilizer application spade 28 is completely inserted into the soil like the conventional fertilizer application device, otherwise, the fertilizer in the feed pipe 21 falls out of the fertilizer pit, this is the biggest difference from the operation of the conventional fertilizing apparatus), that is, the fertilizer pit is gradually formed during the downward movement of the control slide 18 in the drive control cabin 17, and once the feed pipe 20 is in the open state, the fertilizer naturally falls into the fertilizer pit;
when the control slide block 18 moves towards the vicinity of the upper end of the discharge pipe 26, part of the fertilizer in the falling process is pushed into the control bin 17, and the fertilizer remained in the control bin 17 returns to the material guide pipe 21 through the discharge pipe 26;
after the feeding pipe 20 is completely closed, the handle 6 is pressed backwards and downwards, the whole fertilizing device is pulled out by taking the shaft roller 31 tightly attached to the ground as a fulcrum, the shaft roller 31 is taken as a roller to drag the whole fertilizing device away, and finally the fertilizing operation is continuously repeated by stepping the fertilizer pits at intervals of 20-50 cm.
In the embodiment, the driving box 1 and the fertilizer box 5 are detachable installation structures, and when the driving box is not used, the driving box 1 can be used for digging a pit, so that stable manure, soil and miscellaneous manure and the like can be conveniently applied;
finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
