[0034] Referring to Figures 5-8The digging assembly 3 comprises a middle shaft 301 movably sleeved with a bearing between a mounting hole of the mounting plate 209, a digging motor 302 fixedly connected to a top end of a shaft body of the middle shaft 301, the digging motor 302 fixedly mounted on an upper surface of the mounting plate 209, an inner screw piece 303 fixedly sleeved on the shaft body of the middle shaft 301, an axle disc 304 fixedly sleeved on the shaft body of the middle shaft 301, a ring cylinder 305 fixedly connected to a bottom of the axle disc 304, an outer screw piece 306 fixedly mounted on a side surface of the ring cylinder 305, an inner built-in groove provided in the ring cylinder 305, a plurality of ring blocks 307 fixedly mounted on an inner side wall surface of the inner built-in groove of the ring cylinder 305, an inclined block 308 provided on a side surface of each of the ring blocks 307, a guide groove 309 provided on an inner side surface of each of the ring blocks 307, a plurality of limiting blocks 310 fixedly mounted on an inner side wall surface of the inner built-in groove of the ring cylinder 305, a plurality of springs 311 fixedly connected to a top surface of the inner built-in groove of the ring cylinder 305, a ring plate 312 fixedly connected to a bottom end of each of the springs 311, a gear ring 313 fixedly sleeved on an outer side of the ring plate 312, a plurality of guide blocks 314 provided on an outer side surface of the gear ring 313, a plurality of tooth grooves uniformly distributed and provided in a bottom of the gear ring 313, a sleeve ring 315 movably sleeved on an inner ring of the gear ring 313, a plurality of inclined teeth 316 provided on an outer side surface of the sleeve ring 315, the inclined surfaces of the inclined teeth 316 and right side inclined surfaces of the tooth grooves of the gear ring 313 being parallel to each other, a certain degree of static friction force being present between the inclined surfaces of the inclined teeth 316 and left side inclined surfaces of the tooth grooves of the gear ring 313, the thickness of the inclined teeth 316 being greater than the thickness of the tooth grooves of the gear ring 313, the thickness of the inclined teeth 316 having an excess amount outwardly, a thin-wall bearing 317 sleeved on the inner ring of the sleeve ring 315, a limited root plate sleeve 318 sleeved on the thin-wall bearing 317, a sleeve groove 319 provided on an upper end of the limited root plate sleeve 318, the limited root plate sleeve 318 movably sleeving with the thin-wall bearing 317 through the sleeve groove 319, a plurality of through grooves 320 uniformly distributed and provided on the limited root plate sleeve 318, a bottom ring 321 fixedly mounted on a bottom end of the limited root plate sleeve 318, the guide blocks 314 and the guide grooves 309 being vertically aligned, and the inclined blocks 308 and the outer side excess amount of the inclined teeth 316 being vertically aligned.

[0035] In this embodiment, before the device is used, the limit root plate sleeve 318 is first sleeved at the inner ring of the thin-walled bearing 317, and then the limit root plate sleeve 318 is sleeved into the built-in groove of the ring cylinder 305. During the pushing process, the inclined teeth 316 pass between the limit blocks 310 and are in contact with the tooth grooves at the bottom of the gear ring 313. During the pressing and pushing process, the static friction between the top of the inclined teeth 316 and the left side slope of the tooth groove of the gear ring 313 is broken, so that sliding occurs, so that the right rotation sliding of the inclined teeth 316 is in contact with the right side slope of the tooth groove of the gear ring 313. At this time, the inclined teeth 316 are located directly above the limit block 310, and when the spring 311 rebounds downward, the limit block 310 abuts against the inclined teeth 316, so that the limit root plate sleeve 318 can be stably placed in the built-in groove of the ring cylinder 305, thereby completing the initial installation step of the limit root plate sleeve 318. When the digging assembly 3 moves downward for digging, the digging motor 302 drives the middle shaft 301 to rotate, thereby driving the bottom inner screw piece 303 and the outer screw piece 306 to rotate synchronously, so that the bottom ring cylinder 305 and the inner screw piece 303 are drilled into the planting soil together. At this time, the bottom ring 321 is pressed downward during the movement, so that the limit root plate sleeve 318 drives the sleeve ring 315 and the inclined teeth 316 to move upward. The inclined teeth 316 move upward to drive the gear ring 313 to move upward, the guide block 314 slides into the guide groove 309, and the spring 311 is compressed. During the downward digging movement, the inclined teeth 316 will move to the highest point and the thickness allowance will be in contact with the slope of the inclined block 308 at the upper end. During the pressing process, the inclined teeth 316 are driven to turn left by the slope of the inclined block 308. The top of the inclined teeth 316 moves left and contacts the left side slope of the tooth groove of the gear ring 313, and the allowance of the inclined teeth 316 will fit the included angle between the ring block 307 and the inclined block 308. At this time, the inclined teeth 316 have moved to the highest point and remain in this state until the digging reaches the bottom of the soil. When the digging is completed and the upward reset is completed, the gear ring 313 drives the inclined teeth 316 to move downward away from the included angle between the ring block 307 and the inclined block 308 under the rebounding effect of the spring 311. At this time, the inclined teeth 316 will be located between the adjacent limit blocks 310 due to the left moving effect before, so that the limit blocks 310 no longer limit the movement of the inclined teeth 316, so that the limit root plate sleeve 318 is separated from the built-in groove of the ring cylinder 305 and left in the soil, thereby completing the automatic placement effect of the limit root plate sleeve 318. The thin-walled bearing 317 and the sleeve ring 315 are taken out of the limit root plate sleeve 318 and are sleeved on the next limit root plate sleeve 318 to complete the next placement operation.

[0036] The working principle of the present application: before using the device, first of all, the limit root plate sleeve 318 is sleeved on the inner ring of the thin wall bearing 317, then the limit root plate sleeve 318 is sleeved into the built-in groove of the ring cylinder 305, in the process of pushing, the inclined tooth 316 passes between the limiting blocks 310 and is in contact with the tooth groove at the bottom of the gear ring 313, in the process of pressing and pushing, the static friction between the top of the inclined tooth 316 and the left side slope of the gear ring 313 is broken, so that the inclined tooth 316 rotates and slides to the right and is in contact with the right side slope of the gear ring 313, at this time, the inclined tooth 316 is located directly above the limiting block 310, when the spring 311 rebounds downward, the limiting block 310 will resist the inclined tooth 316, so that the limit root plate sleeve 318 can be stably placed in the built-in groove of the ring cylinder 305, thereby completing the initial installation step of the limit root plate sleeve 318, when the digging assembly 3 moves downward for digging, the digging motor 302 drives the middle shaft 301 to rotate, thereby driving the inner screw piece 303 and the outer screw piece 306 at the bottom to rotate synchronously, so that the ring cylinder 305 at the bottom and the inner screw piece 303 are drilled into the planting soil, at this time, the bottom ring 321 is pressed by the soil during downward movement, so that the limit root plate sleeve 318 drives the sleeve ring 315 and the inclined tooth 316 to move upward, the inclined tooth 316 moves upward to drive the gear ring 313 to move upward, the guide block 314 slides into the guide groove 309, and the spring 311 is compressed, during the downward digging movement, the inclined tooth 316 will move to the highest point and its thickness allowance will be in contact with the slope of the upper inclined block 308, during the pressing process, the inclined tooth 316 is driven to turn left by the slope of the inclined block 308, the top of the inclined tooth 316 moves left and is in contact with the left side slope of the gear ring 313, and the allowance of the inclined tooth 316 will fit the included angle between the ring block 307 and the inclined block 308, at this time, the inclined tooth 316 has moved to the highest point and remains in this state until the bottom end of the soil is dug, when the spring 311 rebounds, the gear ring 313 drives the inclined tooth 316 to move downward away from the included angle between the ring block 307 and the inclined block 308, at this time, the inclined tooth 316 will be located between the adjacent limiting blocks 310 due to the previous left moving effect, so that the limiting block 310 no longer limits the movement of the inclined tooth 316, so that the limit root plate sleeve 318 is separated from the built-in groove of the ring cylinder 305 and remains in the soil, thereby completing the automatic placement effect of the limit root plate sleeve 318, the thin wall bearing 317 and the sleeve ring 315 are taken out of the limit root plate sleeve 318 and are sleeved on the next limit root plate sleeve 318 to complete the next placement operation, when the feeding motor 206 drives the push rod 207 to push the connecting plate 203, the sleeve plate 201 movably sleeved on the column pile 102 will move downward synchronously, thereby cooperating with the digging assembly 3 to perform soil digging work, after completing soil digging at one place, the moving motor 212 can drive the lead screw 210 to rotate and drive the sliding plate 208 to move in the sliding groove 202, thereby cooperating with the digging assembly 3 to automatically perform soil digging work at the next place.In this way, the automation effect of the multiple planting and digging work is realized.

4. The kiwifruit root-restriction cultivation treatment device according to claim 3, characterized in that: Each slide plate (208) is equipped with a lead screw (210) for transmission. The shaft of the lead screw (210) is sleeved inside the slide groove (202). Both ends of the shaft of the lead screw (210) are movably sleeved with shaft support plates (211). The shaft support plates (211) are respectively fixedly installed at both ends of the slide groove (202). One end of the shaft of the lead screw (210) is fixedly connected to a moving motor (212). The moving motor (212) is fixedly installed at the outer end of the sleeve plate (201). The other end of the shaft of the lead screw (210) is fixedly sleeved with a pulley (213). The adjacent pulleys (213) are all connected by a synchronous belt (214). The screw pitch and direction of the threads on the lead screw (210) are consistent. The moving motors (212) are of the same type.

5. The method of using the kiwifruit root-restriction cultivation treatment device according to claim 4, characterized in that, Includes the following steps: S1. Before using this device, first, fit the root limiting plate sleeve (318) onto the inner ring of the thin-walled bearing (317), and then fit the root limiting plate sleeve (318) into the built-in groove of the ring cylinder (305). During the pushing process, the helical teeth (316) will pass through the limiting blocks (310) and contact the tooth groove at the bottom of the tooth ring (313). During the pressing and pushing process, the static friction between the top of the helical teeth (316) and the inclined surface on the left side of the tooth groove of the tooth ring (313) will increase. The breakthrough causes sliding, which causes the helical tooth (316) to rotate and slide to the right and come into contact with the right inclined surface of the tooth groove of the tooth ring (313). At this time, the helical tooth (316) is located directly above the limiting block (310). When the spring (311) rebounds downward, the limiting block (310) will abut against the helical tooth (316), so that the root limiting plate sleeve (318) can be stably placed into the inner groove of the ring cylinder (305), thus completing the initial installation steps of the root limiting plate sleeve (318). S2. When the excavating component (3) moves downward to excavate, the excavating motor (302) drives the central shaft (301) to rotate, thereby driving the inner screw plate (303) and outer screw plate (306) at the bottom to rotate synchronously, thereby drilling the bottom ring cylinder (305) and inner screw plate (303) into the planting soil together. At this time, the bottom ring (321) is pressed by the soil during the downward movement, causing the root limiting plate sleeve (318) to drive the collar (315) and the helical tooth (316) to move upward. The upward movement of the helical tooth (316) will push the gear ring (313) to move upward, and the guide block (314) enters the guide groove. (309) Slides in the spring (311) and the spring (311) is compressed. During the downward digging process, the helical tooth (316) will move to the highest point and its thickness margin will contact the inclined surface of the upper inclined block (308). During the pressing process, the helical tooth (316) is driven to turn left by the inclined surface of the inclined block (308). The top of the helical tooth (316) moves to the left and contacts the left inclined surface of the tooth groove of the tooth ring (313). The margin of the helical tooth (316) will match the angle between the ring block (307) and the inclined block (308). At this time, the helical tooth (316) has moved to the highest point and remains in this state until the bottom of the soil is dug. S3. When the excavation is completed and the device is reset upward, the toothed ring (313) drives the helical tooth (316) to move downward away from the angle between the ring block (307) and the helical block (308) under the rebound action of the spring (311). At this time, the helical tooth (316) will be located between the adjacent limiting blocks (310) due to the previous leftward movement effect, so that the limiting blocks (310) no longer restrict the movement of the helical tooth (316), thereby causing the root limiting plate sleeve (318) to detach from the inner groove of the ring cylinder (305) and remain in the soil, thus completing the automatic placement effect of the root limiting plate sleeve (318). S4. Remove the thin-walled bearing (317) and collar (315) from the root limiting plate sleeve (318) and put them on the next root limiting plate sleeve (318) to complete the next placement operation. S5. When the feed motor (206) drives the push rod (207) to push the connecting plate (203), the sleeve plate (201) that is movably connected to the column (102) will move downward synchronously, thereby cooperating with the excavation component (3) to carry out soil excavation work. After completing one soil pit, the moving motor (212) can drive the lead screw (210) to rotate and drive the slide plate (208) to move in the slide groove (202), thereby cooperating with the excavation component (3) to automatically carry out the next soil pit work. In this way, the automation effect of multiple planting pit digging work is achieved.
