[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments: like Figures 1-15 As shown, a tree seedling transplanting and digging device of the present invention includes a tracked frame 1, with side support plates 2 longitudinally arranged on both sides of the tracked frame 1, and a support frame 3 with a reserved opening provided on one side of the two sets of side support plates 2, and a cylinder 4 fixed on the outside of the tracked frame 1; and a rotary digging assembly for tree seedling transplanting and digging is provided on one side of the tracked frame 1, including a dual-head motor 51 transversely arranged on one side of the tracked frame 1, and a differential gear 52 fixed on one output shaft of the dual-head motor 51, and a gear frame 53 that meshes with the differential gear 52 in the support frame 3. After the differential gear 52 and the gear frame 53 are meshed in place, the dual-head motor 51 is controlled to drive the gear frame 53 to rotate three-quarters of a turn in both directions through the differential gear 52. A slide 54 that slides with the support frame 3 is fixed on the toothed frame 53, and a connector 55 that slides with the support frame 3 is fixed on the inner side of the slide 54. A digging head 56 with reinforcing ribs 16 is fixed at the bottom of the connector 55. The toothed frame 53 drives the slide 54 to rotate with the support frame 3. The slide 54 drives the digging head 56, which is reinforced by the reinforcing ribs 16, to rotate and dig around the soil around the roots of the seedlings through the connector 55. The roots of the seedlings are cut off. The seedling roots are dug out by rotary cutting, which is a highly efficient method for transplanting and digging, which improves the efficiency of seedling transplanting, reduces the number of traditional digging arms, and reduces its digging cost and digging burden. Electric slide rails 10 are horizontally mounted on two sets of side support plates 2, and electric slide rail seats 11 slide on the two sets of electric slide rails 10. The two sets of electric slide rail seats 11 are driven by the two sets of electric slide rails 10 to adjust the horizontal displacement, so as to meet the needs of transplanting and soaking the roots after digging up the seedlings. The inner side of the two sets of electric slide rail seats 11 is fixed with a first electric push rod 12 that is fixed to the support frame 3. The first electric push rod 12 drives the support frame 3 and its whole to adjust the height, so as to meet the stroke meshing requirements of the differential gear 52 and the gear frame 53. An electric telescopic rod 13 is fixed to the outer side of the support frame 3 near the slide 54, and a clamping plate 14 with a buffer seat 15 is fixed to the inner side of the two electric telescopic rods 13, as well as rubber clamping heads fixed in an array on the buffer seat 15, to clamp the trunk of the transplanted seedling to prevent the seedling from tilting or falling after it is dug out, and to ensure its stability during the digging.

The dual-head motor 51 drives the driven bevel gear 63 to rotate through the main bevel gear 62. A secondary bevel gear 64 meshes with the outer side of the bevel gear 63, and a turbulence impeller 65, which rotates with the root soaking tank 61, is fixed to the bevel gear 63 via a fan shaft and extends to the bottom of the tracked frame 1. The secondary bevel gear 64 and the turbulence impeller 65 rotate successively driven by the secondary bevel gear 63. The turbulence impeller 65, in the rotating state, turbulently directs the growth regulator in the root soaking tank 61 to the roots of the seedlings and the broken parts, so as to prevent the effective substances in the growth regulator from settling, so that they can be fully absorbed by the roots of the seedlings and the broken parts, which is conducive to the regrowth of the root system and improves the survival rate after transplanting. And the liquid discharge pipe 66 outside the root soaking tank 61 is communicated through a one-way valve, when the absorption protection of the roots and the broken part of the seedling is completed, and when it is needed to clean, the one-way valve is controlled to open, and the growth regulator in the root soaking tank 61 is discharged through the two liquid discharge pipes 66, and new growth regulator is added, and the soil ball is coated on the roots of the seedling after the root soaking is completed.

[0023] And the cylinder barrel 4 is provided with a supercharging assembly, which comprises a five-way valve 74 communicated with the cylinder barrel 4, a cam 71 fixed outside the sub-conical gear 64 through a rotating rod, the cam 71 is continuously rotated by the sub-conical gear 64, the connecting rod 72 is hinged on the cam 71, and the piston 73 sliding with the cylinder barrel 4 is hinged on the connecting rod 72, the cam 71 drives the piston 73 on the connecting rod 72 to reciprocate in the cylinder barrel 4 to generate supercharged pressure; And the first kettle body 75 and the second kettle body 76 are respectively screwed on the five-way valve 74, and kettle covers are screwed on the first kettle body 75 and the second kettle body 76, so that the bactericidal and insecticidal agent is added into the first kettle body 75 in time, and the water-soluble fertilizer nutrient agent is added into the second kettle body 76, to sterilize and kill insects in the soil of the transplanting pit, and provide water-soluble fertilizer nutrition, so that the soil of the transplanting pit has the best planting environment; And the outer end of the five-way valve 74 is provided with a lower insertion assembly, which comprises an angle pipe 81 screwed on the outer end of the five-way valve 74, under the action of pressure force, the bactericidal and insecticidal agent and the water-soluble fertilizer nutrient agent are forced to be supplied into the angle pipe 81, a corrugated pipe 82 is communicated on the angle pipe 81, a main insertion pipe 83 is communicated at the bottom end of the corrugated pipe 82, main spray openings 84 are circumferentially arranged on the main insertion pipe 83, a vice insertion pipe 85 is communicated at the outer end of the main insertion pipe 83 in a triangular equidistant shape, and vice spray openings 86 matched with the main spray openings 84 are circumferentially arranged on the three vice insertion pipes 85, the bactericidal and insecticidal agent and the water-soluble fertilizer nutrient agent are respectively sprayed into the soil of the transplanting pit through the corrugated pipe 82 on the angle pipe 81, the main spray openings 84 on the main insertion pipe 83, and the vice spray openings 86 on the three vice insertion pipes 85, to sterilize and kill insects in the soil of the transplanting pit, and provide water-soluble fertilizer nutrition, to achieve the sterilization and insect killing and water-soluble fertilizer nutrition supplement effect on the soil of the transplanting pit, to provide a better growth environment for the roots of the seedling dug out for transplanting, and to further improve the survival rate of the seedling after transplanting, so as to prevent the seedling after transplanting from dying and causing great loss.

[0024] As Figure 9 And Figure 15As shown, the root soaking assembly is needed to soak the growth regulator for the protection of the roots of the sapling during the digging of the sapling transplanting, and because the roots of the sapling are wrapped with soil balls, the broken roots cannot absorb the growth regulator, affecting the survival rate. The auxiliary assembly is arranged on the rotary digging assembly and the lower inserting assembly, and the auxiliary assembly includes a vibration motor 91 embedded in the inner side of the adapter 55 close to the support frame 3, and an impact head 92 made of rubber is arranged on the vibration motor 91 and is distributed in an interleaved state with the two sets of buffer seats 15. The impact head 92 driven by the vibration motor 91 vibrates and falls the soil around the dug roots of the sapling, which is beneficial to the subsequent full soaking and absorption of the growth regulator by the roots and the broken parts of the sapling, and improves the survival rate after transplanting. The fallen soil balls can be coated after soaking; The other side of the two sets of side support plates 2 is vertically fixed with a second electric push rod 93 through a mounting plate, and a top pressing rod 94 is fixed on the piston rod of the second electric push rod 93, and the bottom of the top pressing rod 94 is fixed with the main inserting pipe 83 through a support. The support on the top pressing rod 94 driven by the second electric push rod 93 provides height stroke adjustment, which is beneficial to the insertion of the main inserting pipe 83 and the three auxiliary inserting pipes 85 into the transplanting pits with different depths, and meets the insertion requirements of the main inserting pipe 83 and the three auxiliary inserting pipes 85 into the transplanting pits with different depths, which is beneficial to the sterilization and pest control of the soil in the transplanting pits with different depths and the supply of water-soluble fertilizer nutrients, and further improves the survival rate of the saplings after transplanting.

[0025] The working principle of the forest tree sapling transplanting and digging device is as follows: first, control the tracked frame 1 to stably move to the sapling to be transplanted, and the sapling trunk passes through the reserved port of the support frame 3 and is located inside the two sets of buffer seats 15, then control the two electric telescopic rods 13 to be opened synchronously and drive the buffer seats 15 on the two sets of clamping plates 14 to clamp the sapling trunk to be transplanted; Then, control the first electric push rod 12 to be opened and drive the gear rack 53 to be lowered through the support frame 3 and be engaged with the engagement part of the differential gear 52. At this time, the support frame 3 also drives the digging head 56 to be inserted into the soil around the roots of the sapling, and then controls the double-head motor 51 to be opened and drives the differential gear 52 to be rotated in forward and reverse directions at a frequency. The differential gear 52 drives the slide 54 to be rotated in forward and reverse directions on the support frame 3 through the engaged gear rack 53, and the number of turns is three quarters of a full turn, and the slide 54 drives the digging head 56 reinforced by the reinforcing ribs 16 to rotate and dig the soil around the roots of the sapling and cut the roots of the sapling; After the tree seedling is excavated, the first electric push rod 12 is controlled to drive the supporting frame 3 to move upward and reset, and the tree trunk is driven to move upward through the two sets of buffer seats 15, and then the vibration motor 91 is controlled to start and the impact head 92 is used to vibrate the excavated tree root soil to fall off, so that the root system is exposed, then the two electric sliding rails 10 are controlled to start synchronously, and the two sets of electric sliding rail sliding seats 11 are driven to move upward through the supporting frame 3 on the first electric push rod 12, and then the tree root is lowered into the growth regulator in the root soaking tank 61, soaked for a long time, so that the tree root and the broken part can absorb the growth regulator in the root soaking tank 61, and the tree root and the broken part are protected; At this time, the toothed rack 53 moves upward with the supporting frame 3, and is separated from the meshing part of the differential gear 52 to the initial state, and before the tree root is moved, the double-head motor 51 is controlled to stop, and then the toothed rack 53 which loses the engagement transmission is manually rotated, so that the excavating head 56 is rotated to the reserved port of the supporting frame 3, and the excavating head 56 moves with the tree root and is attached to the outside of the root soaking tank 61, so as to avoid collision interference; Then the double-head motor 51 is controlled to start again, the main bevel gear 62 is driven to rotate the driven bevel gear 63, and then the driven bevel gear 63 drives the auxiliary bevel gear 64 and the turbulence impeller 65 to rotate in sequence, and the turbulence impeller 65 in the rotating state stirs the growth regulator in the root soaking tank 61 to the tree root and the broken part, so as to prevent the effective substances in the growth regulator from precipitating, so that the tree root and the broken part can fully absorb the growth regulator, when the tree root and the broken part need to be cleaned, the one-way valve is controlled to open, the growth regulator in the root soaking tank 61 is discharged through the two drain pipes 66, and new growth regulator is added, and the tree root is coated with soil balls after root soaking is completed; Then the crawler track frame 1 stably moves the tree root after root soaking to the transplanting pit area, the auxiliary bevel gear 64 drives the cam 71 to continuously rotate, the cam 71 drives the piston 73 on the connecting rod 72 to reciprocate in the cylinder barrel 4 and generates a boost pressure, at the same time, the bactericidal and insecticidal agent in the first kettle body 75 and the water-soluble fertilizer nutrient agent in the second kettle body 76 are supplied into the five-way valve 74, and under the action of the pressure, the bactericidal and insecticidal agent and the water-soluble fertilizer nutrient agent are respectively supplied into the angle pipe 81; Before this, the second electric push rod 93 is controlled to open and drive the main insertion tube 83 and the three auxiliary insertion tubes 85 to insert into the transplanting pit through the support on the top pressure rod 94, then the sterilization and insecticide and the water-soluble fertilizer nutrient agent are respectively sprayed into the soil in the transplanting pit by the corrugated pipe 82 on the corner pipe 81, the main spray port 84 on the main insertion tube 83 and the auxiliary spray port 86 on the three auxiliary insertion tubes 85, the insect eggs in the soil in the transplanting pit are sterilized and disinfected, and the water-soluble fertilizer nutrient supply is provided, then the seedling is lowered into the transplanting pit, and after the filling is completed, the two groups of buffer seats 15 are controlled to release the clamping measure of the main stem of the seedling and are separated from the seedling, thus the transplanting work of the seedling is completed.
