[0014] The present invention has the following beneficial effects:

[0015] 1. For a combined soil preparation machine for garden planting trees provided in this application, the positive gear is driven to rotate by the first soil loosening transmission rod and the second soil loosening transmission rod. The helical gear changes the rotation direction of the positive gear. The helical gear drives the conical rod and the conical spiral blade to rotate. The conical spiral blade operates on the land that needs to be plowed and stubble-removed. The rotating blades of the conical spiral blade rotate and cut the stubble into pieces. At the same time, the conical spiral blade rotates and drills into the land to plow and loosen the land. It realizes that the transverse position of the conical spiral blade for plowing is wider and the plowed soil layer is deeper. The blades of the conical spiral blade rotate and cut the stubble into pieces, making it rot faster in the land as new nutrients, and continuously rotating and cutting the plowed soil, so as to break the lumpy soil, make the soil in the plowed area more uniform, make the soil looser, and increase the air permeability effect of the soil.

[0016] 2. The combined soil preparation machine for garden planting wood provided by this application drives the transmission shaft to rotate towards the traction hitch through the operation of the gravel motor. The gravel blade teeth on the transmission shaft rotate towards the gravel strip, and the protruding tooth discs of the gravel blade teeth press the stones downward in the rotation direction. The larger stones are crushed by the extrusion of the gravel blade teeth and the gravel strip, and the crushed stones fall back into the land through the gaps between the gravel blade teeth and the gravel strip. One end of the transmission shaft away from the platform is close to the land, and the rotating gravel blade teeth suppress the land leveled by the V-shaped frame, realizing the integration of gravel crushing and suppression. While the gravel blade teeth crush the stones, they also compact the surface of the subsoiled land.

[0017] 3. The combined soil preparation machine for garden planting wood provided by this application has a circular ring sleeved on the outer peripheral surface of the eccentric wheel. The eccentric wheel rotates inside the circular ring, driving the second extension rod to slide back and forth inside the sliding sleeve, thereby driving the flat plate, the gravel strip, and the V-shaped frame to move horizontally. The continuously rotating gravel strip assists the gravel blade teeth in crushing the stones, realizing the accumulation of stones between the gravel blade teeth and the gravel strip. The horizontal movement of the gravel strip increases the extrusion of the stones, making the process of crushing the stones smoother. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the second traction frame 104 away from the vertical column 101 is connected to the stable support device 5. On both sides of the lower end of the platform 105, hydraulic components 106 are fixedly installed. The lower ends of the hydraulic components 106 are installed with wheels 107 through wheel frames. When the soil preparation machine is working, the hydraulic components 106 retract to drive the wheels 107 to rise, and the gravel rolling and pressing roller mechanism 8 contacts the ground for support. When the soil preparation machine needs to be transported after the work is completed, the hydraulic components 106 extend to make the wheels 107 descend, and the wheels 107 contact the ground for support. The hydraulic components 106 lift the soil preparation machine off the ground, and the wheels 107 move. On one side end of the platform 105 away from the vertical column 101, a hook 2 is fixedly installed. The number of hooks 2 is two groups. A rope 201 is hung on the two groups of hooks 2. One end of the rope 201 away from the hook 2 is hung with a square tube 202. Fixed pins are welded on both sides of the square tube 202. The fixed pins of the square tube 202 are hung on the two groups of ropes 201. The square tube 202 is used for leveling the land. The soil loosening motor 3 and the gravel motor 4 are placed on the upper end of the platform 105. A first transmission belt 301 is sleeved on the motor shaft of the soil loosening motor 3. One end of the first transmission belt 301 away from the soil loosening motor 3 is sleeved with a thin transmission rod 302. Both ends of the thin transmission rod 302 are sleeved with first support frames 304. At positions away from the first support frames 304 at both top ends of the thin transmission rod 302, two second transmission belts 303 are respectively installed. The two second transmission belts 303 at the same end of the thin transmission rod 302 are set as a group. Therefore, there is a group of second transmission belts 303 at each end of the thin transmission rod 302. Each group of the two second transmission belts 303 is respectively sleeved with a first soil loosening transmission rod 305 and a second soil loosening transmission rod 306. From Attachment Figure 1Looking at it, the two second drive belts 303 in each group are divided into a front second drive belt 303 and a rear second drive belt 303. Therefore, the front second drive belts 303 of the two groups are connected in series forward at both ends of the first soil-loosening drive rod 305, and the rear second drive belts 303 of the two groups are connected in series backward at both ends of the second soil-loosening drive rod 306. A stable support device 5, a spiral soil-loosening device 6, and a stone conveying device 7 are placed on the first soil-loosening drive rod 305 and the second soil-loosening drive rod 306. The number of the stable support device 5, the spiral soil-loosening device 6, and the stone conveying device 7 is set to multiple groups, and they are arranged alternately in the front and back. When the soil-loosening motor 3 operates, the motor shaft of the soil-loosening motor 3 rotates to drive the first drive belt 301 and the second drive belt 303 to rotate. The second drive belt 303 drives the first soil-loosening drive rod 305 and the second soil-loosening drive rod 306 to rotate respectively, and the first soil-loosening drive rod 305 and the second soil-loosening drive rod 306 rotate in the direction of the hook 2 in unison. The first soil-loosening drive rod 305 and the second soil-loosening drive rod 306 drive the spiral soil-loosening device 6 and the stone conveying device 7 to loosen the soil and convey the stones. A third drive belt 401 is sleeved on the motor shaft of the stone-crushing motor 4. One end of the third drive belt 401 away from the stone-crushing motor 4 is sleeved with a thick drive rod 402. Second support frames 404 are arranged on the surfaces of both ends of the thick drive rod 402 away from the third drive belt 401. Fourth drive belts 403 are sleeved on the two top ends on both sides of the thick drive rod 402. One end of the fourth drive belt 403 away from the thick drive rod 402 is sleeved with a stone-crushing and rolling mechanism 8. The stone-crushing and rolling mechanism 8 includes a rolling roller 801, stone-crushing blade teeth 802, and a drive shaft 803. A stone-crushing and leveling device 9 is engaged with the surface of the stone-crushing blade teeth 802. The stone-crushing and leveling device 9 is used to assist the stone-crushing and rolling mechanism 8 to crush stones and level the land. The stone conveying device 7 conveys stones to the position where the stone-crushing blade teeth 802 and the stone-crushing and leveling device 9 are engaged for stone crushing. When the stone-crushing motor 4 operates, the motor shaft of the stone-crushing motor 4 rotates to drive the third drive belt 401, and the third drive belt 401 drives the fourth drive belts 403 at both ends to rotate. The fourth drive belt 403 drives the rolling roller 801 to rotate. The rolling roller 801 makes the stone-crushing blade teeth 802 rotate in the direction of the towing hook interface 1. The stone-crushing blade teeth 802 serve as a support point and compact the loose surface soil.

[0034] Refer to the appendix Figure 3 , appendix Figure 4 , appendix Figure 5 , the spiral soil-loosening device 6 includes a helical gear 601, a tapered rod 602, and a tapered spiral blade 603. A tapered spiral blade 603 is fixedly installed on the circumferential surface of the tapered rod 602 away from the first soil-loosening drive rod 305. A helical gear 601 is fixedly installed at one end of the tapered rod 602 close to the first soil-loosening drive rod 305. The stable support device 5 is arranged above the helical gear 601.

[0035] The stable support device 5 includes an L-shaped fixing bracket 501, a square fixing member 502, a first sliding ring 503. Mudguards 506 are connected and installed at both ends of the first soil-loosening transmission rod 305 and the second soil-loosening transmission rod 306. The lower end of the L-shaped fixing bracket 501 is fixedly installed with the square fixing member 502. A circular through-hole is opened at the lower end of the square fixing member 502. The first sliding ring 503 is placed in the circular through-hole of the square fixing member 502. The first sliding ring 503 is sleeved on the first soil-loosening transmission rod 305. A spur gear 505 is fixedly sleeved on one side of the first soil-loosening transmission rod 305 close to the square fixing member 502. The spur gear 505 meshes with a helical gear 601. The upper end of the L-shaped fixing bracket 501 is fixedly installed with a vertical fixing rod 504. The upper end of the vertical fixing rod 504 is fixedly installed on the bottom surface of the platform 105. The circumferential surface on one side of the vertical fixing rod 504 away from the first soil-loosening transmission rod 305 is fixedly connected to one end of the second traction frame 104. The lower end of the vertical fixing rod 504 is fixedly installed with an inclined fixing member 5041. A circular through-hole is opened at the lower end of the inclined fixing member 5041. A second sliding ring 5042 is placed in the circular through-hole of the inclined fixing member 5041. The second sliding ring 5042 is sleeved on the outer circumference of the tapered rod 602 close to the helical gear 601. The settings of the L-shaped fixing bracket 501 and the vertical fixing rod 504 can fix the positions of the first soil-loosening transmission rod 305 and the spiral soil-loosening device 6. The rotation of the first soil-loosening transmission rod 305 drives the spur gear 505 to rotate. The rotation direction of the spur gear 505 is changed by the helical gear 601. The spur gear 505 drives the tapered spiral blade 603 to rotate. The front part of the tapered spiral blade 603 drills into the soil through rotation to plow and loosen the soil. At the same time, the lower end of the vertical fixing rod 504 can be changed to a spring. The spring of the vertical fixing rod 504 is connected to the inclined fixing member 5041, so that the spiral soil-loosening device 6 can make a small displacement and at the same time does not disengage from the meshing of the helical gear 601 and the spur gear 505. When the tapered spiral blade 603 encounters a large resistance, the spring under the vertical fixing rod 504 unloads the force to avoid damaging the spiral soil-loosening device 6.

[0036] See the appendix Figure 3 , appendix Figure 4 , appendix Figure 5 , appendix Figure 6, the stone conveying device 7 includes a conveyor belt 701, conveying strip plates 702, elliptical plates 703, and sleeves 704. The sleeves 704 are divided into upper and lower groups of sleeves 704. Two groups of elliptical plates 703 are fixedly installed on the opposite surfaces of the two groups of sleeves 704. Two groups of double-headed rods 705 are fixedly installed on the opposite surfaces of the two groups of elliptical plates 703. The two ends of the double-headed rod 705 are provided with inclined surfaces. The upper sleeve 704 is sleeved on the circumferential surface of the first soil-loosening transmission rod 305. A sliding rod 706 is sleeved inside the lower sleeve 704. The conveyor belt 701 is placed on the outer circumference of the double-headed rod 705. One end of the conveyor belt 701 is sleeved on the circumferential surface of the sliding rod 706, and the end of the conveyor belt 701 away from the sliding rod 706 is sleeved on the circumferential surface of the first soil-loosening transmission rod 305. The upper sleeve 704 is located at both ends of the conveyor belt 701. Multiple groups of strip-shaped notches are formed on the surface of the conveyor belt 701. Conveying strip plates 702 are fixedly installed on the surface of the conveyor belt 701. A V-shaped guide plate 707 is fixedly installed on the side of the upper sleeve 704 away from the elliptical plate 703. Multiple groups of V-shaped guide plates 707 are provided. One group of V-shaped guide plates 707 is connected to every two groups of upper sleeves 704. A vertical rod 708 is fixedly installed at the V-shaped bottom opening position of the V-shaped guide plate 707 through a flat plate. The upper end of the vertical rod 708 is fixedly installed on the bottom surface of the platform 105. Through the setting of the vertical rod 708, the position of the V-shaped guide plate 707 is fixed. The V-shaped guide plate 707 is fixedly connected to the upper sleeve 704, so that the lower sleeve 704, the sliding rod 706, and the conveyor belt 701 are stably in an inclined position, so that the position of the lower sleeve 704 will not change when encountering obstacles during the operation of the land preparation machine. Its principle is similar to fixing one side of the rear end of a seesaw, and the front seesaw will not move up and down. When small stones and soil fall into the inside of the conveyor belt 701, the elliptical plates 703 and double-headed rods 705 inside the conveyor belt 701 prevent the accumulation of smaller stones, so that the soil and stones fall to both sides of the inclined surface of the double-headed rod 705. At the same time, when the conveyor belt 701 runs upward to the upper sleeve 704, the soil accumulated in the sandwich layer of the conveyor belt 701 and the elliptical plate 703 at the position of the lower sleeve 704 is carried to the position of the upper sleeve 704, so that it is pushed out of the sandwich layer of the conveyor belt 701 and the elliptical plate 703 at the position of the lower sleeve 704, avoiding the accumulation of too much soil and stones resulting in the jamming of the conveyor belt 701.

[0037] The crushed stone rolling and pressing roller mechanism 8 includes a rolling and pressing roller 801, crushed stone blade teeth 802, and a transmission shaft 803. The crushed stone blade teeth 802 are installed on the outer circumferential surface of the rolling and pressing roller 801. The number of the crushed stone blade teeth 802 is multiple groups. From the attachment Figure 9It can be obtained that in the present application, every eight gravel blade teeth 802 are connected end to end along the circumferential direction of the rolling press roller 801 to form a protruding tooth disc. A plurality of protruding tooth discs are arranged along the axial direction of the rolling press roller 801. From the direction of the central axis of the rolling press roller 801, the gravel blade teeth 802 of the plurality of protruding tooth discs form a V-shaped arrangement from the middle of the central axis of the rolling press roller 801 to both sides, which is simply called the V-shaped gravel blade tooth group. Since each protruding disc has eight gravel blade teeth 802, eight V-shaped gravel blade tooth groups are formed along the circumferential direction of the entire rolling press roller 801. The number of gravel blade teeth 802 in the circumferential and axial directions of the present application can be set according to actual needs. The V-shaped gravel blade tooth group is used to gather the stones at both ends of the rolling press roller 801 towards the middle of the rolling press roller 801 and realize the extrusion of the stones. Drive shafts 803 are fixedly installed at both ends of the rolling press roller 801 respectively. An eccentric wheel 806 is fixedly installed on a side surface of the drive shaft 803 away from the rolling press roller 801. A gravel leveling device 9 is arranged on the outer circumferential surface of the eccentric wheel 806. The eccentric wheel 806 is coaxial with the drive shaft 803. When the drive shaft 803 drives the eccentric wheel 806 to rotate half a circle, that is, 180 degrees, during the rotation process, the gravel leveling device 9 is pushed by the eccentric wheel 806, and the gravel leveling device 9 gradually moves to a position away from the drive shaft 803. When the drive shaft 803 drives the eccentric wheel 806 to continuously rotate, the gravel leveling device 9 continuously moves closer to and away from the drive shaft 803. A fixed collar 804 is sleeved on the circumferential surface of the drive shaft 803 close to the rolling press roller 801. A connecting rod 805 is fixedly installed on the upper end of the circumferential surface of the fixed collar 804. The upper end of the connecting rod 805 is fixedly installed on the bottom surface of the platform 105. The fixed collar 804 and the connecting rod 805 play a role in supporting and fixing the position of the rolling press roller 801. A fourth transmission belt 403 is sleeved on the circumferential surface of the drive shaft 803 away from the rolling press roller 801. When the gravel motor 4 runs and rotates towards the traction hitch 1, it drives the fourth transmission belt 403 to rotate. The fourth transmission belt 403 drives the drive shaft 803, the rolling press roller 801, and the eccentric wheel 806 to rotate. The rotation of the eccentric wheel 806 drives the gravel leveling device 9 to move horizontally. The horizontal movement of the gravel leveling device 9 avoids the accumulation of stones and increases the extrusion of the stones, making the process of crushing stones smoother.

[0038] The gravel leveling device 9 includes a flat plate 901, gravel bars 902, and vertical reinforcing ribs 903. Gravel bars 902 are installed on one side of the flat plate 901 close to the transmission shaft 803. The number of gravel bars 902 is multiple groups, and the multiple groups of gravel bars 902 mesh with the gravel blade teeth 802. Multiple groups of vertical reinforcing ribs 903 are installed on the side surface of the flat plate 901 away from the transmission shaft 803. A horizontal reinforcing rib 9031 is inserted in the middle of the multiple groups of vertical reinforcing ribs 903. A column 904 is fixedly installed at the lower end of the horizontal reinforcing rib 9031. The number of columns 904 is set to be multiple groups. One end of the multiple groups of columns 904 away from the vertical reinforcing rib 903 is fixedly installed with a V-shaped frame 905. The V-shaped frame 905 is used to level the turned-out soil. First extension rods 906 are respectively installed at both ends of the horizontal reinforcing rib 9031. A second extension rod 907 is installed at one end of the two first extension rods 906 away from the horizontal reinforcing rib 9031. A sliding sleeve 908 is sleeved at the middle position of the circumferential surface of the second extension rod 907. A fixed long rod 9081 is fixedly installed on the circumferential surface of the sliding sleeve 908. The upper end of the fixed long rod 9081 is fixedly installed on the bottom surface of the platform 105. A circular ring 909 is fixedly installed at one end of the second extension rod 907 away from the first extension rod 906. The shape of the circular ring 909 is a vertically placed ellipse. The circular ring 909 is sleeved on the outer circumferential surface of the eccentric wheel 806. The eccentric wheel 806 rotates inside the circular ring 909. When the eccentric wheel 806 rotates in the circular ring 909, it only contacts the left and right inner side walls in the horizontal direction of the circular ring 909, realizing the function of pushing the circular ring 909 to move horizontally back and forth, and preventing the circular ring 909 from moving in the vertical direction, ensuring that the circular ring 909 can drive the second extension rod 907 to slide back and forth inside the sliding sleeve 908, thereby driving the flat plate 901, the gravel bars 902, and the V-shaped frame 905 to move horizontally. The sliding sleeve 908 and the fixed long rod 9081 serve as the support frames for stabilizing the gravel leveling device 9.

[0039] Working principle of the specific implementation method: When the towing hitch 1 is attached to an agricultural tractor and enters the field for work, the hydraulic component 106 retracts to drive the wheels 107 to rise, and the spiral soil loosening device 6 and the gravel compaction roller mechanism 8 come into contact with the land. The entire land preparation machine is pulled in the direction of the towing hitch 1 through the reinforcing beam 102, the first towing frame 103, and the second towing frame 104. The soil loosening motor 3 operates, and the soil loosening motor 3 drives the first soil loosening transmission rod 305 and the second soil loosening transmission rod 306 to rotate, causing the spiral soil loosening device 6 and the stone conveying device 7 installed on the first soil loosening transmission rod 305 and the second soil loosening transmission rod 306 to work for soil loosening and stone conveying. The rotation of the first soil loosening transmission rod 305 drives the spur gear 505, and the spur gear 505 drives the helical gear 601 meshing with it. The helical gear 601 changes the rotation direction of the spur gear 505. The rotation of the helical gear 601 drives the conical spiral blade 603. The top of the conical spiral blade 603 away from the helical gear 601 drills into the soil layer through rotation for soil loosening. During the soil loosening process, the blades of the conical spiral blade 603 overturn the soil and stones to both sides of the conical spiral blade 603. The stone conveying device 7 is arranged on both sides of the conical spiral blade 603, so that the soil and stones are piled up on the conveyor belt 701. The strip-shaped notches on the conveyor belt 701 filter the soil and small stones. The larger stones are driven by the rotation of the first soil loosening transmission rod 305 to drive the conveyor belt 701. The conveying strip 702 on the conveyor belt 701 carries the stones towards the upper sleeve 704. When reaching the position of the upper sleeve 704, the stones fall onto the V-shaped guide plate 707. Due to the setting of the V-shaped guide plate 707, the larger stones fall onto the stone conveying device 7 on the second soil loosening transmission rod 306. The stone conveying device 7 on the second soil loosening transmission rod 306 continues to convey upwards. The larger stones fall to the position where the gravel blade teeth 802 mesh with the flat plate 901. The gravel motor 4 operates, and the gravel motor 4 drives the transmission shaft 803 to rotate in the direction of the towing hitch 1. The gravel blade teeth 802 on the transmission shaft 803 rotate towards the gravel strip 902. The protruding tooth discs of the gravel blade teeth 802 press the stones in the rotation direction. The larger stones are crushed by the extrusion between the gravel blade teeth 802 and the gravel strip 902. The gap between the gravel blade teeth 802 and the gravel strip 902 is adjusted to different widths according to the size of the stones that the user needs to crush. The crushed stones fall back into the land through the gap between the gravel blade teeth 802 and the gravel strip 902. One end of the transmission shaft 803 away from the platform 105 is close to the land, and the rotating gravel blade teeth 802 compact the land leveled by the V-shaped frame 905, making the surface soil compact and preventing the surface soil from being blown away by strong winds. The setting of the gravel blade teeth 802 and the gravel strip 902 solves the problem of crushing the stones contained in the soil. At the same time, the gravel blade teeth 802 are used to compact the soil, reducing the addition of equipment and lowering labor and financial resources. At the same time, for the land required for tree planting, the use of the conical spiral blade 603 has a wider lateral position for plowing and a deeper plowing layer of the land.The blades of the conical spiral blade 603 rotate and cut the stubble, and the stubble after being broken remains in the soil and rots faster as new nutrients. The soil turned out by ploughing is continuously rotated and cut, so as to break up the lumpy soil, make the soil in the ploughed area more uniform, make the soil looser, and increase the air permeability of the soil.
