[0039] Embodiment 2:

[0040] The root lifting component includes a first transfer rod 301 rotatably mounted on the outer wall of the arc-shaped swing block 206. The number of the first transfer rods 301 is multiple, and the positions of the multiple first transfer rods 301 correspond to the positions of the multiple fertilizer injection plug rods 207. A planetary gear 302 is fixedly mounted on the outer wall of the first transfer rod 301. A sun gear 303 is fixedly mounted on the bottom of the arc-shaped donation block 204. The bottom of the sun gear 303 is meshed with the tops of the multiple planetary gears 302. A driving pulley 304 is fixedly mounted on the outer wall of the first transfer rod 301. A belt 305 is sleeved on the outer wall of the driven pulley 304, and a second transfer rod 306 is rotatably installed on the lower part of the outer side surface of the fertilizer injection plug rod 207. A driven pulley 307 is fixedly installed on the outer wall of the second transfer rod 306. The driven pulley 307 is located at the bottom of the driving pulley 304. One end of the belt 305 away from the driving pulley 304 is sleeved on the periphery of the driven pulley 307. A soil-breaking disc 308 is fixedly installed on the outer wall end of the second transfer rod 306. A plurality of soil-breaking sharp rods 309 distributed at equal angles are fixedly installed on the outer wall of the soil-breaking disc 308.

[0041] Specifically, the output shaft of the servo motor 401 drives the active synchronous wheel 402 to rotate, and further drives the driven synchronous wheel 404 and the hollow shaft 405 to rotate under the transmission action of the synchronous belt 403, thereby driving the telescopic shaft 4051, the rocker arm 407 and the swing pin 408 to rotate. The swing pin 408 rotates, so that the swing seat 409 swings back and forth, driving the arc swing block 206 to slide back and forth along the inner wall of the T-shaped arc groove 205. The reciprocating sliding of the arc swing block 206 drives multiple fertilizer injection rods 207 to move together. At the same time, the arc swing block 206 also drives multiple first transfer rods 301 and planetary gears 302 to swing together, so that the planetary gears 302 move along the bottom of the sun gear 303. The part reciprocates, driving the active pulley 304 to reciprocate together, and further drives the driven pulley 307 and the second transfer rod 306 to reciprocate under the connecting action of the belt 305. The rotation of the second transfer rod 306 drives the soil-breaking disk 308 and multiple soil-breaking pointed rods 309 to reciprocate together.

Furthermore, through the reciprocating rotation of multiple soil-breaking disks 308, the roots of herbaceous plants on the surface near the tree trunk can be cut off, thereby preventing the herbaceous plants near the tree trunk from absorbing fertilizer.

[0042] Furthermore, a reset block 601 is fixedly installed on the upper left side of the telescopic square bar 203, a second straight groove 2002 is penetrated through the left side of the guide plate 201, the reset block 601 is slidably located inside the second straight groove 2002, a spring seat 602 is fixedly connected to the middle of the left wall of the T-shaped arc groove 205, a reset spring 603 is commonly connected between the reset block 601 and the spring seat 602, and a lever 507 is fixedly installed on the top of the pawl 504. When the telescopic square bar 203 moves downward, it drives the reset block 601 to move downward, causing the reset spring 603 to be compressed and stored. When the fertilizer is applied, the lever 507 is pulled to disengage the pawl 504 from the telescopic square bar 203, and the reset spring 603 is elastically released to push the reset block 601 and the telescopic square bar 203 to slide downward, further resetting the fertilization component and the root lifting component upward.

[0043] Furthermore, a plurality of key slots 4052 distributed at equal angles are provided inside the hollow shaft 405, and a plurality of key blocks 4053 distributed at equal angles are fixedly mounted on the outer wall of the telescopic shaft 4051. The outer wall of the key block 4053 is slidably connected to the inner wall of the key slot 4052. By setting the key slot 4052 and the key block 4053 in slidable connection, while ensuring the sliding connection state between the hollow shaft 405 and the telescopic shaft 4051, a torque limiting effect is further provided between the hollow shaft 405 and the telescopic shaft 4051, thereby ensuring that the hollow shaft 405 always has the ability to transmit torsional force to the telescopic shaft 4051, thereby causing the rocker arm 407 and the swing pin 408 to rotate.

[0044] Furthermore, a clearance groove 2041 is provided in the middle of the right side surface of the arc-shaped donation block 204, and the clearance groove 2041 is connected to the inside of the T-shaped arc groove 205. The swing seat 409 is movably located inside the clearance groove 2041. By providing the clearance groove 2041, it is ensured that the reciprocating swing of the swing seat 409 will not be interfered by the arc-shaped donation block 204, thereby ensuring that the swing seat 409 can swing smoothly.

[0045] In the present scheme, when the uniform fertilizer application device for garden tree maintenance is working, the gardener pushes the device to one side of the tree so that the arc-shaped fertilizer application block 204 surrounds the outer side of the trunk and ensures that the center of the arc-shaped fertilizer application block 204 is roughly consistent with the center of the trunk. The servo motor 401 is started, and the output shaft of the servo motor 401 drives the active synchronous wheel 402 to rotate, and further drives the driven synchronous wheel 404 and the hollow shaft 405 to rotate under the transmission action of the synchronous belt 403, thereby driving the telescopic shaft 4051, the rocker arm 407 and the swing pin 408 to rotate;

[0046] The hollow shaft 405 rotates to drive the bottom cam 506 to rotate, pushing the guide wheel 505 downward, and the guide wheel 505 moves downward to drive the pawl 504 and the loading seat 502 to move downward, compressing the second spring 508. Further, under the rebound effect of the fertilizer injection hole 208 and the continuous rotation effect of the bottom cam 506, the pawl 504 pushes the telescopic square bar 203 meshed therewith to move slowly downward, and the telescopic square bar 203 presses downward to drive the arc-shaped application block 204, the arc-shaped swing block 206 and the multiple fertilizer injection rods 207 to move downward, so that the multiple fertilizer injection rods 207 are inserted into the soil around the tree trunk, and the fertilizer supply pump 701 is started to transport the fertilizer inside the fertilizer box 7 to the inside of the fertilizer distribution groove 2061 through the fertilizer pipe 702 and the fertilizer supply pipe 2063, and then input into the inside of the multiple fertilizer injection rods 207 through the multiple fertilizer distribution holes 2062, and output to the soil around the tree trunk through the multiple fertilizer injection holes 208, thereby completing the application of fertilizer;

[0047] The swing pin 408 rotates, causing the swing seat 409 to swing back and forth, driving the arc swing block 206 to slide back and forth along the inner wall of the T-shaped arc groove 205. The arc swing block 206 slides back and forth to drive multiple fertilizer injection rods 207 to move together. At the same time, the arc swing block 206 also drives multiple first transfer rods 301 and planetary gears 302 to swing together, causing the planetary gears 302 to reciprocate along the bottom of the sun gear 303, driving the driving pulley 304 to reciprocate together, and further driving the driven pulley 307 and the first transfer rods 301 and the planetary gears 302 to rotate back and forth along the bottom of the sun gear 303. The second adapter rod 306 rotates back and forth, and the rotation of the second adapter rod 306 drives the soil-breaking disk 308 and multiple soil-breaking pointed rods 309 to rotate back and forth together. The multiple soil-breaking pointed rods 309 rotate back and forth to break the soil that needs to be fertilized, thereby facilitating the insertion of multiple fertilizer injection rods 207 deep into the soil, and the reciprocating swing of the multiple soil-breaking pointed rods 309 can loosen the soil to facilitate better release of fertilizer. Furthermore, through the reciprocating rotation of multiple soil-breaking disks 308, the roots of herbaceous plants on the surface near the tree trunk can be cut off to prevent the herbaceous plants near the tree trunk from absorbing fertilizer.
