[0007] Preferably, the drive mechanism includes a drive motor and multiple connecting shafts. The output shaft of the drive motor and the middle of the rightmost connecting shaft are both fixedly connected to a side pulley, and the middle of the remaining connecting shafts are both fixedly connected to a middle pulley.

[0009] Preferably, the two through holes are located on the left and right sides of the adjusting seat, and the two mounting cavities are located on the front and rear sides of the adjusting seat and are symmetrically arranged. The permanent magnet block and the sliding block are both located inside the mounting cavity and are slidably connected to it.

[0010] Preferably, the top end of the multi-stage protective sleeve is fixedly connected to the lower surface of the connecting column, the bottom end of the multi-stage protective sleeve is rotatably connected to the upper surface of the adjusting seat, and the threaded rod is located inside the multi-stage protective sleeve.

[0011] Preferably, the connecting shaft is rotatably connected to the connecting column, the scraper is in contact with the upper surface of the connecting column, and there are gaps between the connecting column and the front and rear inner walls of the housing.

[0012] Preferably, the inner wall of the cylinder has two limiting grooves, the sealing ring is slidably connected to the limiting grooves, and the curved surface of the threaded rod has two rectangular grooves.

[0013] Preferably, the outer side of the sliding block is provided with a protrusion, the protrusion is adapted to the limiting groove, and the inner end of the sliding block is adapted to the rectangular groove.

[0014] The beneficial effects of this invention are as follows: 1. This invention moves the stirring rod to the soil-turning position. At this point, the sliding block is inserted into the limiting groove, and the adjusting seat is located above the threaded rod. The drive motor rotates forward, driving multiple connecting shafts to rotate. The connecting shafts then drive the threaded rod below to rotate, thus allowing the stirring rod to penetrate deeper into the soil. When the bottom of the stirring rod reaches the target depth, the electromagnetic block is energized in the reverse direction, attracting the permanent magnet block to move inward. This causes the sliding block to be pulled out of the limiting groove, with its inner end inserted into the rectangular groove. The continuing rotation of the connecting shaft drives the adjusting seat and the stirring rod to rotate, thereby performing the soil-turning operation. At this time, the seedling is located between the two stirring rods, thus avoiding damage to the seedling. Furthermore, the soil-turning depth can be adjusted according to the seedling's growth cycle.

[0015] 2. In this invention, the electromagnetic block is energized in the forward direction, which pushes the permanent magnet block to move outward. The sliding block moves accordingly, and the drive motor works. Through transmission, multiple connecting shafts rotate simultaneously. The connecting shafts drive the threaded rod below to rotate, which in turn causes the adjusting seat to rotate. When the sliding block rotates to the limiting groove on the inner wall of the cylinder, the sliding block will penetrate into the limiting groove, thus stopping the adjusting seat from rotating. The existing soil pressing plate is fixedly installed at the bottom of multiple mixing rods. The continuously rotating threaded rod will drive the adjusting seat to move downward, which in turn drives the soil pressing plate at the bottom of the mixing rod to move downward until the soil below is flattened, thus completing the soil pressing operation after walnut planting.

[0016] 3. This invention involves adding fertilizer or liquid into the box, then reversing the current to the electromagnetic block, causing the permanent magnet block to move inward. This pulls the sliding block out of the limiting groove, with its inner end penetrating the rectangular groove. This drives the motor to rotate forward, causing multiple connecting shafts to rotate. The connecting shafts then drive the threaded rod below to rotate, which in turn drives the stirring rod to rotate. The scraper follows the rotation, scraping waste into the space above the adjusting seat. Fertilizer enters the through hole. When the control valve is opened, fertilizer or liquid enters the material channel and is discharged into the soil, thus simultaneously completing the fertilization or watering process.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A drive wheel 5 is fixedly installed in the middle of the drive shaft 4. Front wheels 6 are fixedly installed at both ends of the drive shaft 4. A housing 7 is fixedly connected to the curved surface of the connecting column 1. A box body 8 is fixedly connected to the upper surface of the housing 7.

A stirring mechanism 15 is provided in the middle of the cylinder 13. Drive mechanism 16 is located inside connecting column 1.

[0021] The stirring mechanism 15 includes a threaded rod 151, with an adjusting seat 152 threadedly connected to the middle of the threaded rod 151. The adjusting seat 152 has two through holes 153 and two mounting cavities 154 inside. A stirring rod 155 is fixedly connected to the bottom of the through holes 153. A material channel 156 is opened inside the stirring rod 155. A control valve 157 is fixedly installed at the top of the material channel 156. An electromagnetic block 158 is fixedly installed inside the mounting cavity 154. A permanent magnet block 159 is provided on the outside of the electromagnetic block 158. A sliding block 1510 is fixedly connected to the middle of the permanent magnet block 159. The sliding block 1510 is slidably connected to the electromagnetic block 158. Two sealing rings 1511 are rotatably connected to the curved surface of the adjusting seat 152. A multi-level protective sleeve 1512 is provided on the upper surface of the adjusting seat 152. Its function is as follows: the stirring rod 155 moves to the soil-turning position, at which point the sliding block 1510 is inserted into the limiting groove, and the adjusting seat 152 is located above the threaded rod 151. The drive motor 161 rotates forward, driving multiple connecting shafts 162 to rotate. The connecting shafts 162 drive the threaded rod 151 below to rotate, thus causing the stirring rod 155 to penetrate deeper into the soil. When the bottom end of the stirring rod 155 penetrates the soil to the target depth, the electromagnetic block 158 is energized in the reverse direction, attracting the permanent magnet block 159 to move inward, causing the sliding block 1510 to be pulled out from the limiting groove, with its inner end inserted into the rectangular groove. The connecting shaft 162 continues to rotate, driving the adjusting seat 152 and the stirring rod 155 to rotate, thereby performing the soil-turning operation. At this time, the seedling is located between the two stirring rods 155, thus avoiding damage to the seedling, and the soil-turning depth can be adjusted according to the seedling's growth cycle.

[0022] The drive mechanism 16 includes a drive motor 161 and multiple connecting shafts 162. The output shaft of the drive motor 161 and the middle of the rightmost connecting shaft 162 are both fixedly connected to a side pulley 163. The middle of the remaining connecting shafts 162 are all fixedly connected to a middle pulley 164. A scraper 165 is fixedly connected to the upper part of the connecting shaft 162. A middle belt 166 is connected between two adjacent middle pulleys 164. A side belt 167 is connected between the side pulley 163 and the adjacent middle pulley 164.

[0023] The top end of the threaded rod 151 is fixedly connected to the bottom end of the connecting shaft 162. The adjusting seat 152 is adapted to the cylinder 13. Two through holes 153 are located on the left and right sides of the adjusting seat 152. Two mounting cavities 154 are located at the front and rear of the adjusting seat 152 and are symmetrically arranged. The permanent magnet block 159 and the sliding block 1510 are both located inside the mounting cavity 154 and are slidably connected to it. Their function is that when the electromagnetic block 158 is energized in the positive direction, the permanent magnet block 159 is pushed to move outward, and the sliding block 1510 will move accordingly. At this time, the drive motor 161 works, and through transmission, multiple connecting shafts 1 Simultaneously rotating shaft 162 drives the threaded rod 151 below to rotate, which in turn causes the adjusting seat 152 to rotate. When the sliding block 1510 rotates to the limiting groove on the inner wall of cylinder 13, the sliding block 1510 will penetrate into the limiting groove, thus stopping the adjusting seat 152 from rotating. The existing soil pressing plate is fixedly installed at the bottom of the multiple mixing rods 155, and the continuously rotating threaded rod 151 will drive the adjusting seat 152 to move downward, thereby driving the soil pressing plate at the bottom of the mixing rod 155 to move downward until the soil below is flattened, thus completing the soil pressing operation after walnut planting.

[0024] The top end of the multi-stage protective sleeve 1512 is fixedly connected to the lower surface of the connecting column 1, the bottom end of the multi-stage protective sleeve 1512 is rotatably connected to the upper surface of the adjusting seat 152, and the threaded rod 151 is located inside the multi-stage protective sleeve 1512.

[0025] The connecting shaft 162 is rotatably connected to the connecting column 1, the scraper 165 is in contact with the upper surface of the connecting column 1, and there are gaps between the connecting column 1 and the front and rear inner walls of the housing 7.

[0026] The inner wall of the cylinder 13 has two limiting grooves, and the sealing ring 1511 is slidably connected to the limiting grooves. The curved surface of the threaded rod 151 has two rectangular grooves. The outer side of the sliding block 1510 has a protrusion that matches the limiting groove. The inner end of the sliding block 1510 matches the rectangular groove. Its function is that when fertilizer or liquid is added into the box 8, the electromagnetic block 158 is energized in the reverse direction, attracting the permanent magnet block 159 to move inward, causing the sliding block 1510 to be pulled out from the inside of the limiting groove. Deep inside the rectangular trough, the drive motor 161 rotates forward, causing multiple connecting shafts 162 to rotate. The connecting shafts 162 drive the threaded rod 151 below to rotate, which in turn drives the stirring rod 155 to rotate. The scraper 165 rotates accordingly, scraping the waste material into the space above the adjusting seat 152. Fertilizer enters the through hole 153. When the control valve 157 is opened, fertilizer or liquid enters the material channel 156 and is discharged into the soil, thus completing the fertilization or watering work simultaneously.

[0027] Working principle: During the soil compaction operation after sowing, the control motor 10 operates, driving the drive wheel 11 to rotate. The drive wheel 11 drives the transmission wheel 5 to rotate via the front belt 12. The transmission wheel 5 drives the front wheels 6 at both ends to rotate via the transmission shaft 4, thereby moving the compaction plate directly above the area to be compacted. The electromagnetic block 158 is energized in the forward direction, thus pushing the permanent magnet block 159 to move outward, and the sliding block 1510 will follow. At this time, the drive motor 161 operates, rotating forward to drive the left side pulley 163 to rotate. The left side pulley 163 drives the middle pulley 164 to rotate via the left side belt 167. After the transmission of multiple middle pulleys 164 and the middle belt 166, the rightmost middle pulley 164 drives the rightmost side pulley 164 via the right side belt 167. The connecting shaft 162 rotates, causing multiple connecting shafts 162 to rotate simultaneously. The connecting shaft 162 drives the threaded rod 151 below to rotate, which in turn causes the adjusting seat 152 to rotate. When the sliding block 1510 rotates to the limiting groove on the inner wall of the cylinder 13, the sliding block 1510 will penetrate into the limiting groove, thus stopping the adjusting seat 152 from rotating. The existing soil pressing plate is fixedly installed at the bottom of multiple mixing rods 155. The continuously rotating threaded rod 151 will drive the adjusting seat 152 to move downward, thereby driving the soil pressing plate at the bottom of the mixing rod 155 to move downward until the soil below is flattened. Then the drive motor 161 reverses to drive the soil pressing plate to move upward, while controlling the motor 10 to work and drive the soil pressing plate to move to the next soil pressing position. When turning the soil, the mixing rod 155 moves to the turning position. At this time, the sliding block 1510 is inserted into the limiting groove, and the adjusting seat 152 is located above the threaded rod 151. The drive motor 161 rotates forward, driving multiple connecting shafts 162 to rotate. The connecting shafts 162 will drive the threaded rod 151 below to rotate, thereby causing the mixing rod 155 to penetrate into the soil. When the bottom of the mixing rod 155 penetrates the soil to the target depth, the electromagnetic block 158 is energized in the reverse direction, attracting the permanent magnet block 159 to move inward, causing the sliding block 1510 to be pulled out from the limiting groove, with its inner end penetrating into the rectangular groove. The connecting shaft 162 continues to rotate, which will drive the adjusting seat 152 and the mixing rod 155 to rotate, thereby performing the turning operation. During the soil turning operation, fertilizer or liquid can be added into the box 8. As the stirring rod 155 rotates, the rotating scraper 165 will scrape the waste into the space above the adjusting seat 152, and the fertilizer will enter the through hole 153. When the control valve 157 is opened, the fertilizer or liquid will enter the material channel 156 and be discharged into the soil, thus completing the fertilization or watering work simultaneously.
