The steps and the principle are as follows:
1) the guide rail sliding block 30 is slidably mounted on one of the semicircular guide rails 12;
2) the two clamping components 10 are combined and spliced around the fruit tree;
3) inserting the fixing rod 13 into the ground;
4) the bolts 20 are screwed into the threaded holes of the threaded plates 14 of two different clamping assemblies 10;
5) moving the flat car 50 to a position farthest from the fruit tree;
6) the flat car 50 is started to advance around the fruit tree, and the first motor 70 and the second motor 150 are started.
When the flat car 50 advances around a fruit tree, the ditching plow 190 completes ditching, the rotation of the soil covering plate 200 completes fertilizing, and the soil covering plate 200 completes soil covering. At the same time, the rotation of the first motor 70 causes the connection belt 40 to be wound around the belt shaft 101. When flatbed 50 fertilizies around the fruit tree, flatbed 50 also diminishes from the distance of fruit tree, and the fertilizer injection unit of this application is the spiral that takes the fruit tree as the center around the fertilization orbit of fruit tree promptly. The nutrient in the fertilizer can be absorbed by the root system radiating outwards from the center of the trunk.
In the first embodiment, the second motor fixing assembly 110 is a plate.
Because the closer the distance to the fruit tree, the denser the root system of the fruit tree, the greater the amount of fertilizer that needs to be applied.
In a second scheme, the second motor fixing assembly 110 includes a guide sleeve 111, a guide rod 112, a first spring 114, and a guide sleeve fixing rod 115;
one end of the guide rod 112 is fixed with one end of the second motor 150 far away from the rotating shaft;

when the connection band 40 is not wound around the winding band shaft 101, the free end of the guide bar 112 is always in contact with the winding band shaft 101 by the elastic force of the first spring 114.
Referring to fig. 8, the grooves 1601 on the discharging shaft 160 are spiral-shaped, and the cross section of the grooves 1601 is triangular (see fig. 6); the cross section of the groove 1601 of the discharging shaft 160 is gradually reduced from the end adjacent to the second motor 150 to the end far away from the second motor 150.
The principle is as follows: referring to fig. 2 and 4, when the fertilizer applying apparatus of the present application applies fertilizer around a fruit tree, the closer the fertilizer applying apparatus of the present application is to the fruit tree, the more the connecting band 40 is wound around the band shaft 101. The connecting belt 40 wound around the belt winding shaft 101 pushes the guide bar 112 to the side away from the belt winding shaft 101, while the discharge shaft 160 also moves in the discharge pipe 1701 to the side away from the belt winding shaft 101; that is, the closer the fertilizer applying device is to the fruit tree, the larger the cross section of the groove 1601 in the blanking pipe 1701 on the discharging shaft 160 is, the larger the cross section of the groove 1601 is, the larger the fertilizer amount is discharged; put another way, the closer the fertilizer injection unit of this application is to the fruit tree the more its chemical fertilizer volume of applying.
Through a large number of testing machines, the fertilizer amount discharged by the discharge shaft 160 is found to be unstable, and the discharged fertilizer has a discontinuity phenomenon; careful study found that when the pitch of the grooves 1601 is larger than the lumen size of the blanking pipe 1701 in the axial direction of the discharge shaft 160, the grooves 1601 in the blanking pipe 1701 sometimes have no downward portion.
Further, (referring to fig. 8) the pitch of the grooves 1601 is smaller than the lumen size of the blanking pipe 1701 in the axial direction of the discharge shaft 160. At any time, a portion of the grooves 1601 will face downward and discharge fertilizer from them through the lower end of the pipe 1701.
Further, the pitch of the grooves 1601 is 1 to 1.5 times the lumen size of the blanking pipe 1701 in the axial direction of the discharge shaft 160.
During the rotation of the discharging shaft 160 for discharging fertilizer, since the grooves 1601 are spiral grooves wound on the outer side of the discharging shaft 160, the fertilizer in the discharging pipe 1701 will also be discharged along the axial direction of the discharging shaft 160 through the spiral grooves 1601 without passing through the lower end of the discharging pipe 1701, and then through the pipe wall where the discharging shaft 160 penetrates through the discharging pipe 1701 (see fig. 8).
Also comprises a leakage-proof component which is arranged on the outer wall of the shell,
the leakage-proof assembly comprises a bearing 180, a cylinder housing 210, a piston rod 220, a second spring 230 and a sealing member 240;

one end of the cylinder housing 210 is fixed on the side surface of the inner ring of the bearing 180;
the piston of the piston rod 220 is slidably sleeved in the inner cavity of the cylinder housing 210;
a triangular sealing element 240 is fixed at one end of the piston rod 220, which is positioned at the outer side of the cylinder shell 210;
the second spring 230 is located between the piston of the piston rod 220 and the inner ring of the bearing 180, and the elastic force of the second spring 230 always presses the sealing member 240 into the groove 1601 of the discharging shaft 160;
two side walls of the blanking pipe 1701 through which the discharging shaft 160 penetrates are provided with a leakage-proof assembly.
The sealing member 240 can follow the groove 1601 of the discharging shaft 160; and the sealing member 240 is always kept in close contact with the groove 1601 when the discharging shaft 160 moves along its axis; the fertilizer in the discharge pipe 1701 is not discharged through the pipe wall where the discharge shaft 160 penetrates the discharge pipe 1701 in the axial direction of the discharge shaft 160.
Further, the cross sections of the sealing member 240 and the groove 1601 are regular triangles.
