The present invention drives the fixing frame to move downward by the telescopic end of the electric telescopic rod fixed at the middle position of the bottom of the top plate, so that the fixing frame drives the soil compacting ring at the bottom to be pressed tightly against the bottom end of the seedling, and the output end of the first motor fixed at the bottom of the positioning seat drives the gear to rotate, so that the soil compacting of the seedlings is more sufficient, and the damage of the soil compacting device to the forestry seedlings is reduced, the survival rate of forestry seedlings is increased, the labor cost is reduced, and the practicality of the soil compactor for planting forestry seedlings is increased.

By setting the counterweight structure 7, it is convenient to use water to flexibly counterweight the counterweight structure 7, and it is convenient to compact soils of different looseness according to usage requirements. In addition, the water can be fully shaken and mixed with the nutrient solution during the tamping process, which is convenient for the later fertilization and irrigation of the compacted seedlings. After the water is used, the counterweight structure 7 will be lightened, which is convenient for the flexible transportation of the soil compactor and improves the performance of the soil compactor to a certain extent; by setting the dilution structure 8, it is convenient to flexibly dilute the nutrient solution with a high residual concentration on the bottom side of the folding cylinder 702, avoiding the situation where the high residual concentration on the bottom side of the folding cylinder 702 is easily wasted, and further improving the performance of the soil compactor; by setting the locking structure 9, it is convenient to flexibly lock the rack 6 during the process of lifting the rack 6, and it is convenient for the subsequent operation of the upper metal plate 701, and further improving the performance of the soil compactor.

[0044] The specific arrangement and function of the counterweight structure 7, the dilution structure 8 and the locking structure 9 will be described in detail below.

[0045] like Figure 1-Figure 7 As shown, the counterweight structure 7 also includes a winding rod 712 fixedly connected to the surface of the upper metal plate 701. The winding rod 712 is an "L"-shaped structure. An elastic rope 713 is fixedly connected to the end side of the winding rod 712. A hook 714 is fixedly connected to the other end of the elastic rope 713. A hook hole 717 is provided on the side wall of the winding rod 712. At this time, the hose 704 is retracted and wound around the side wall of the winding rod 712, and the hook 714 is pulled and hooked on the inner side of the hook hole 717, so that the wound hose 704 can be pressed and fixed, thereby preventing the shaking of the hose 704 from affecting the normal compaction of the ground.

[0046] The side wall of the upper metal plate 701 is fixedly connected with a second mounting block 709, the side wall of the lower metal plate 703 is fixedly connected with a first mounting block 707, the second mounting block 709 is internally slidably connected with a limiting rod 708, the limiting rod 708 is fixedly connected to the upper surface of the first connecting block, the second mounting block 709 is internally threadedly connected with a bolt 710, and the side wall of the limiting rod 708 is provided with a plug hole 711, the size of the plug hole 711 is adapted to the size of the bolt 710. The limiting rod 708 slides inside the second mounting block 709, which plays a role in limiting the telescopic direction of the folding cylinder 702, avoiding that the staff can insert the bolt 710 into the inner side of different plug holes 711 according to the use requirements during the later use of the folding cylinder 702, so as to realize the fixing work of the position of the limiting rod 708 after the twitching, thereby facilitating the fixing work of the folding cylinder 702 after the extension. The side wall of the rack 6 is fixedly connected with a positioning block 720, and the internal thread of the positioning block 720 is connected with a screw pin 721. The surface of the circular plate 719 is provided with two circular holes 722, and the size of the circular holes 722 matches the size of the screw pin 721. The lower surface of the lower metal plate 703 is evenly provided with a plurality of reserved grooves 706. The upper metal plate 701 is retracted to the top of the base 1, and the screw pin 721 is inserted into the inner side of the corresponding circular hole 722, so that the position of the upper metal plate 701 after retraction can be fixed. At this time, the occupied space and weight of the soil compactor can be reduced, and the transportation of the soil compactor is convenient. The reserved groove 706 provided on the lower metal plate 703 can avoid the situation that the lower metal plate 703 tamps the ground relatively flat, which is inconvenient for the subsequent ventilation of the roots of the seedlings. By setting the reserved groove 706 provided on the lower metal plate 703, the ventilation work after the ground is compacted is convenient.

[0047] like Figure 1-Figure 4 and Figure 8-Figure 9As shown, the dilution structure 8 also includes a baffle ring 810 fixedly connected to the side wall of the pre-storage tank 801, and two baffle rods 806 are fixedly connected to the surface of the upper metal plate 701, and the baffle ring 810 is located between the baffle rod 806 and the upper metal plate 701. The setting of the baffle rod 806 facilitates the limiting work of the baffle ring 810 and the pre-storage tank 801. The surface of the baffle ring 810 is provided with an indication hole 811, and the indication hole 811 is a triangular structure. The pre-storage tank 801 is rotated according to the indication direction of the indication hole 811, and the third through hole 809 on the connector 808 can be rotated to a position staggered with the first through hole 805. The surface of the upper metal plate 701 is glued with an elastic pad 804, and the elastic pad 804 is located on the inner side of the limiting tube 803. The surface of the elastic pad 804 is provided with a second through hole 807, and the first through hole 805, the second through hole 807 and the third through hole 809 are all semicircular structures. By providing the elastic pad 804 , the tightness of sealing the third through hole 809 is improved.

[0048] like Figure 1-Figure 2 and Fig.10 As shown, the side wall of the slide frame 92 is provided with an inclined surface 94. The tooth block on the rack 6 has an irreversible effect in the process of relative movement with the inclined surface 94 on the slide frame 92. A spring 93 is fixedly connected between the slide frame 92 and the rectangular block 91. The slide frame 92 will be pressed against the side wall of the rack 6 by the elastic force of the spring 93 on the rectangular block 91. A connecting pin 95 is fixedly connected to the side wall of the slide frame 92, and a baffle 96 is rotatably connected to the other end of the connecting pin 95. After pulling the baffle 96 and moving it to the side position of the limit frame 5, the baffle 96 on the connecting pin 95 is rotated to the side position of the limit frame 5, and then the normal transmission between the gear 4 and the rack 6 can be realized.

[0049] Working principle: After the planting soil compactor is unloaded from the vehicle, the planting soil compactor can be pushed to a location with a water source, and the threaded block 718 can be opened to add water to the water injection hole of the upper metal plate 701. The water source will be injected into the inner side of the folding cylinder 702 between the upper metal plate 701 and the lower metal plate 703, thereby improving the weight increase of the counterweight structure 7, wherein the limit rod 708 slides inside the second mounting block 709, which plays a role in limiting the telescopic direction of the folding cylinder 702, avoiding the later use of the folding cylinder 702. The staff can insert the bolt 710 into the inner side of different sockets 711 according to the use requirements, which can realize the fixing of the position of the limit rod 708 after pulling, thereby facilitating the fixing of the folding cylinder 702 after extension. In order to facilitate the compaction work around the seedlings according to the soil conditions in the later stage, the folding cylinder 702 swings, and the threaded block 718 is rotated to the inside of the upper metal plate 701 to achieve the sealing work of the water injection hole. In the process of injecting water, a certain amount of nutrient solution can be added to the inside of the water injection hole. After the upper metal plate 701 is sealed, the motor 3 can be started, and the motor 3 will drive the gear 4 to rotate, and the gear 4 will drive the rack 6 to move upward. When the surface of the gear 4 with a smooth surface rotates to a position facing the rack 6, the counterweight structure 7 will fall quickly, thereby facilitating the compaction work of the soil around the seedlings. In the process of compacting the ground, the water inside the folding cylinder 702 will be fully shaken and mixed with the nutrient solution. When it is necessary to finish the work, first put the upper metal plate 701. When the plate 701 is driven to the top side position, the valve 715 can be opened, and the hand-held shower head 705 can be sprayed out from the shower head 705 along the fixed pipe 716 and the hose 704, thereby facilitating the irrigation and fertilization of the compacted seedlings and further improving the planting effect of the seedlings. After the water is released, the weight of the counterweight structure 7 will be reduced. At this time, the hose 704 is retracted and wound around the side wall of the winding rod 712, and the hook 714 is pulled and hooked on the inner side of the hook hole 717, so that the wrapped hose 704 can be pressed and fixed, and the shaking of the hose 704 can be avoided to affect the normal compaction of the ground. At this time, the screw pin 721 inside the positioning block 720 can be rotated, and the screw pin 721 can be pulled out from the inner side of the original circular hole 722. By flipping the circular block under the rack 6, the upper metal plate 701 can be retracted to the top of the base 1, and the screw pin 721 can be inserted into the inner side of the corresponding circular hole 722 to fix the position of the upper metal plate 701 after retraction. At this time, the space occupied and the weight of the soil compactor can be reduced, which is convenient for the transportation of the soil compactor. The reserved groove 706 opened on the lower metal plate 703 can prevent the lower metal plate 703 from tamping the ground relatively flat, which is inconvenient for the subsequent ventilation of the roots of the seedlings. By setting the reserved groove 706 opened on the lower metal plate 703, the ventilation work after the ground is compacted is convenient. By setting the counterweight structure 7, it is convenient to use water to flexibly counterweight the counterweight structure 7, and it is convenient to compact the soil with different looseness according to the use requirements.In addition, the water can be fully shaken and mixed with the nutrient solution during the tamping process, which facilitates the fertilization and irrigation of the compacted seedlings in the later stage. After the water is used, the weight structure 7 will be lightened, which facilitates the flexible transportation of the soil compactor and improves the performance of the soil compactor to a certain extent.

[0050] First, rotate the pre-storage tank 801 according to the direction indicated by the indicator hole 811, and rotate the third through hole 809 on the connector 808 to a position staggered with the first through hole 805. At this time, open the threaded column 802 to add pre-used water to the inside of the storage tank. By setting the elastic pad 804, the tightness of the sealing of the third through hole 809 is improved. The retaining ring 810 will be squeezed by the position of the retaining rod 806 to make the connector 808 tightly against the surface of the elastic pad 804. When the water with nutrient solution inside the folding cylinder 702 is about to flow out, rotate the pre-storage tank 801 again. Storage tank 801, according to the direction indicated by the indicator hole 811, flips the third through hole 809 to a position corresponding to the first through hole 805 and the second through hole 807, and the water will flow to the upper surface of the lower metal plate 703. At this time, the nutrient solution with a high precipitation concentration on the upper surface of the lower metal plate 703 can be diluted. By setting the dilution structure 8, the flexible dilution of the nutrient solution with a high residual concentration on the bottom side of the folding cylinder 702 is facilitated, avoiding the waste caused by the high residual concentration on the bottom side of the folding cylinder 702, and further improving the performance of the soil compactor.

[0051] The motor 3 generally does not have a self-locking structure. After pulling the blocking bar 96 and moving the blocking bar 96 to the side of the limiting frame 5, the blocking bar 96 on the connecting pin 95 is rotated to rotate the blocking bar 96 to the side of the limiting frame 5. At this time, the normal transmission between the gear 4 and the rack 6 can be realized. When it is necessary to move the rack 6 to a high point for locking, the blocking bar 96 located on the side wall of the limiting frame 5 can be rotated out, and the sliding frame 92 will be pressed against the side wall of the rack 6 by the elastic force of the spring 93 on the rectangular block 91. In the process of driving the rack 6 to move upward, the tooth block on the rack 6 is in contact with the inclined surface 94 on the sliding frame 92. The relative movement has an irreversible effect. After the rack 6 is lifted to a certain height, the motor 3 can be turned off. At this time, the sliding frame 92 will be stuck in the position between two adjacent tooth blocks on the rack 6, so that the position of the rack 6 can be fixed after it is lifted, which is convenient for the subsequent spraying of the liquid in the hose 704 after lifting and the retraction of the upper metal plate 701 on the upper side of the base 1. By setting the locking structure 9, the flexible locking work of the rack 6 in the process of lifting the rack 6 is facilitated, and the subsequent operation of the upper metal plate 701 is facilitated, thereby further improving the performance of the soil compactor.
