[0024] To make the purpose, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-8 As shown, the present invention provides an integrated hole digging and soil mixing equipment for fruit tree planting, with a screw-in sleeve 13 as the central support component, which houses an axially movable spiral drilling structure 8 inside, and integrates a storage box 1 and a soil mixing box 2 on the outside. The storage box 1 is connected to the soil mixing box 2 through a rotary lifting drive assembly 3, which realizes the axial movement and rotation of the soil mixing box 2 relative to the storage box 1. Figure 4As shown, a drilling opening 201 is provided at the middle portion of the bottom side of the mixing box 2 , the diameter of which is adapted to the spiral drilling structure 8 , allowing the spiral blades 804 of the spiral drilling structure 8 to pass through to complete the drilling operation, and allowing the drilled soil to fall into the interior of the mixing box 2 through the opening.

[0026] When the mixing box 2 is driven by the rotary lifting drive assembly 3 to move axially along the screw-in sleeve 13 to its closest position to the storage box 1, the inner edge of the drilled opening 201 tightly abuts the end of the screw-in sleeve 13, forming an abutment seal to prevent soil leakage during the mixing process. A feeding structure is provided at the bottom of the storage box 1 to transport stored fertilizer to the mixing box 2. At the same time, the stirring rod 9 extending from the bottom side of the storage box 1 generates relative motion with the rotating material as the mixing box rotates, achieving uniform mixing of the soil and fertilizer. When the inner edge of the drilled opening 201 forms an abutment seal with the end of the screw-in sleeve 13, the end of the stirring rod 9 slides and abuts against the inner bottom wall of the mixing box 2.

[0027] See the instructions attached Figure 3 As shown, the outer contours of the storage box 1 and the mixing box 2 are both cylindrical, and the screw-in sleeve 13 passes through the axes of the two to form a coaxial arrangement. The upper side of the mixing box 2 is open and is sleeved on the outside of the storage box 1. Driven by the rotary lifting drive assembly 3, the mixing box 2 can rotate around the axis and slide axially relative to the storage box 1. A feeding port is provided at the lowest point of each spiral sliding base plate 103, and a feeding structure is provided at the corresponding position. A spiral sliding base plate 103 is provided at the bottom of the storage box 1, and its number corresponds to the feeding structure and is more than two, and is evenly distributed radially around the axis. A feeding pipe port 101 is provided at the top of the storage box, and a sealing end cover 102 is provided for dust prevention and sealing.

[0028] See the instructions attached Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, the rotary lifting drive assembly 3 includes dual functions of rotary driving and lifting driving: Rotational Drive: A ring gear 309 is fixedly mounted on the outside of the mixing chamber 2 and meshes with a gear 310. Gear 310 is driven by the third motor 301. Power is transmitted through a slewing bearing 308 between the motor base 302 and the mixing chamber 2, causing the mixing chamber to rotate about the axis of the sleeve. The gear transmission area is protected by a gear cover 305.

[0029] Lifting Drive: The motor base 302 is connected to the crossbeam 304 via two or more connecting rods 303. The middle portion of the crossbeam 304 is fixed to the push rod of the first hydraulic cylinder 306. The first hydraulic cylinder 306 is fixed to the outside of the storage box 1 via a cylinder base 307. Its telescopic movement drives the crossbeam 304 to slide up and down along the connecting rods 303, thereby driving the axial movement of the mixing box 2 along the threaded sleeve 13. The connecting holes in the crossbeam 304 are clearance-matched with the connecting rods 303, and the connecting rods are fixed in position by set bolts, achieving locking of the lifting stroke.

[0030] See the instructions attached Figure 7 and Figure 8 As shown, the feeding structure includes a rotating shaft 105 disposed at the feeding port and six or more evenly distributed feeding blades 106 on the outside. The rotating shaft 105 is driven by a first motor 104 fixed to the storage box 1. As the feeding blades 106 rotate with the rotating shaft, they push the fertilizer on the spiral sliding base 103 from the feeding port into the mixing box 2.

[0031] See the instructions attached Figure 4 、 Figure 7 and Figure 8 As shown, the auger drilling mechanism 8 comprises a sixth motor 801, a connecting sleeve 802, a drill rod 803, and spiral blades 804. The output shaft of the sixth motor 801 is detachably connected to the drill rod 803 via the connecting sleeve 802, facilitating replacement of drill rods of different specifications. Two spiral blades 804 are evenly spaced about the axis of the drill rod 803. As they rotate, they convey the cut soil along the threaded sleeve 13 to the drill opening 201 of the mixing chamber 2.

[0032] See the instructions attached Figure 2 、 Figure 3 and Figure 4 As shown, the screw-in drive guide assembly 4 includes a vertical rail 401 fixed to one side of the storage box 1, a vertical slide 405 is provided inside the vertical rail 401, and a lead screw 407 and a vertical slider 406 are arranged in the slide. The lead screw 407 is driven to rotate by the fourth motor 408, and the vertical slider 406 cooperates with the lead screw through a threaded hole to achieve the lifting movement along the vertical rail. The vertical slider 406 is connected to the fixed plate 403 through the cross bar 402 and the suspension rod 404, and the sixth motor 801 is fixed on the fixed plate. More than three wheel rods 409 are circumferentially arranged on the outer side of the fixed plate 403, and more than two guide wheels 410 are installed on each wheel rod. The guide wheels are in rolling contact with the inner wall of the screw-in sleeve 13 to ensure the verticality and stability of the spiral drilling structure 8 when it is lifted or lowered.

[0033] See the instructions attached Figure 1 、 Figure 2 and Figure 4 As shown, a driven wheel structure 5 and a driving wheel structure 6 are provided at the bottom of the device: Driven wheel structure 5: Four driven wheels are arranged in a rectangular array outside the storage box 1. Each driven wheel consists of a support frame 501, a second hydraulic cylinder 502, a first wheel frame 503, and a first moving wheel 504. The second hydraulic cylinder 502 can independently adjust the height of the driven wheel, and in conjunction with the level sensor 12 on the storage box 1, it can achieve automatic leveling of the equipment on uneven terrain.

[0034] The driving wheel structure 6 includes a second wheel frame 601 fixed to the lower end of the vertical rail 401 and a second movable wheel 602. The second movable wheel 602 is driven by a fifth motor 603. The fifth motor 603 is arranged inside the second movable wheel 602 to realize the equipment movement function. A wheel arch cover 604 is arranged above it to protect the transmission components.

[0035] Lifting support structure 7: Electric telescopic rods 701 are set on both sides of the vertical rail 401, and the lower end of the push rod is connected to the support block 703. During operation, the electric telescopic rods are extended to make the support block fall to the ground, supporting and fixing the equipment to prevent shaking during drilling and mixing.

[0036] Through the above-mentioned specific structural design, the horizontal sensor 12 is used to check the levelness, and when cooperating with the digital display control panel 10 to drive and adjust the lifting support structure 7 and each driven wheel structure 5, the forward drilling angle of the spiral drilling structure 8 is perpendicular to the ground, thereby ensuring the verticality of the hole.

[0037] A discharge port 202 is defined at one side of the bottom of the mixing box 2, with a sealed cover 203 positioned above it. The sealed cover 203 is connected to the mixing box 2 via a deflection rod 205, the other end of which is driven for rotation by a second motor 204. When material is to be discharged, the second motor 204 drives the deflection rod 205 to rotate, causing the sealed cover 203 to rotate open around the discharge port axis, allowing the mixed material to be discharged under gravity. After the operation is complete, the motor reverses direction to close the cover, automating the discharge process. A digital control panel 10 drives the lifting support structure 7 and the various driven wheel structures 5 to adjust the tilt angle of the mixing box 2. After mixing is complete, the mixing rod 9 cooperates with the rotating lifting drive assembly 3 to prevent soil from sticking to the bottom of the mixing box 2. After the soil is concentrated at the discharge port 202, it is rotated to the lowest position, and the sealed cover 203 is opened for discharge.

[0038] Working principle: When in use, the fifth motor 603 of the driving wheel structure 6 drives the second moving wheel 602 to rotate, thereby moving the device in the planting area; the first moving wheel 504 of the driven wheel structure 5 turns accordingly to adapt to different paths.

[0039] When preparing to drill a hole, the electric telescopic rod 701 of the lifting support structure 7 is extended to push the support block 703 to the ground, thereby supporting and fixing the entire device to prevent shaking during drilling and mixing.

[0040] The horizontal sensor 12 monitors the tilt state of the equipment in real time. When tilt is detected, it controls the extension and retraction of the corresponding second hydraulic cylinder 502 to adjust the height of the driven wheel. If the left side tilts downward, the left hydraulic cylinder push rod is extended to lift the left driven wheel; the four groups of driven wheels are adjusted independently until the horizontal sensor shows that the equipment is level.

[0041] The fourth motor 408 of the precession drive guide assembly 4 rotates the lead screw 407, which, through the threaded hole, drives the vertical slider 406 downward along the vertical slot 405 of the vertical rail 401. The vertical slider drives the sixth motor 801 and drill rod 803 of the spiral drilling mechanism 8 axially along the precession sleeve 13 via the crossbar 402, the suspension rod 404, and the fixed plate 403. The sixth motor 801 drives the drill rod 803 to rotate at high speed through the connecting sleeve 802. The spiral blades 804 cut the soil and transport the debris upward from the hole. The debris falls into the mixing box 2 through the drilled opening 201 of the mixing box 2, completing the soil collection.

[0042] During the drilling process, the guide wheel 410 on the outside of the fixed plate 403 rolls in contact with the inner wall of the screw-in sleeve 13, forming a multi-point support guide to prevent the drill rod from deflecting; and the drilling depth is precisely controlled by the number of rotations of the fourth motor 408 to achieve standardized operation.

[0043] The push rod of the first hydraulic cylinder 306 of the rotary lifting drive assembly 3 is extended, pushing the crossbeam 304 and the connecting rod 303, so that the mixing box 2 is axially close to the storage box 1 along the screw-in sleeve 13; when the mixing box moves to the nearest position, the inner edge of the drilled opening 201 abuts against the end of the screw-in sleeve, forming a mechanical seal to prevent material leakage during mixing.

[0044] The third motor 301 drives the gear 310, which, through the ring gear 309, rotates the mixing box 2 about the axis of the screw-in sleeve. The stirring rod 9, fixed to the storage box 1, is located within the mixing box, generating relative motion with the rotating material, creating a stirring effect and ensuring uniform mixing of the soil and fertilizer. During this process, the first motor 104 of the feeding mechanism drives the rotating shaft 105 and the material-dispensing blades 106, pushing the fertilizer on the spiral slide base 103 in the storage box 1 through the feeding port to the mixing box 2. The inclined design of the spiral slide base automatically aggregates the fertilizer toward the feeding port, improving feeding efficiency.

[0045] The second motor 204 rotates the deflection rod 205, driving the sealing cover 203 to rotate about the axis of the soil discharge port 202, opening the discharge port. The mixing box 2 can be tilted by rotating the lifting drive assembly 3, and the mixing rod 9 cooperates to gather the mixed material near the discharge port. Under the action of gravity, the mixed material is discharged from the discharge port 202 and falls into the pre-drilled planting hole. After the material is discharged, the second motor 204 rotates in the opposite direction to close the sealing cover 203.

[0046] The coordinated adjustment of the level sensor 12, the driven wheel and the supporting structure enables the equipment to operate stably on terrain with a slope of ±15°, broadening the application scenarios.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
