Cylinder barrels 4 are fixedly connected to both sides of the top of the side frames 3. Side covers 5 are fixedly connected to the outer sides of the cylinder barrels 4 through brackets.

[0042] A lifting assembly is provided inside the side frame 3, and the lifting assembly includes a double-headed motor 61 fixed to the outside of the side frame 3, and a cam 62 fixed to one output shaft of the double-headed motor 61.

[0044] like Figure 5-Figure 12 As shown, the lifting assembly also includes a horizontal frame 63 sliding on the cam 62, and the double-headed motor 61 drives the horizontal frame 63 through the cam 62 to perform reciprocating lifting movements, and the outer side of the horizontal frame 63 is fixedly connected to a slide 64 that slides with the side frame 3, the outer side of the cylinder 4 is fixedly connected to a first circuit breaker 65, and the outer side of the slide 64 is fixedly connected to a first electromagnet 66 for opening and closing control of the first circuit breaker 65, and the outer side of the first electromagnet 66 is electromagnetically attracted by a first fixed magnet 67. The two groups of first circuit breakers 65 control the two groups of first electromagnets 66 and the first fixed magnet 67 to be in an electromagnetic attraction and positioning state, and then the horizontal frame 63 drives the first fixed magnet 67 to perform reciprocating lifting movements through the two groups of first electromagnets 66 on the two groups of slides 64;

[0045] The turning assembly also includes a turning frame 73 fixed in an array to the bottom of the horizontal plate 72, and soil guides 74 are fixedly connected on all four sides of the turning frame 73. The two sets of slides 64 drive the horizontal plates 72 on the two light rods 71 to perform reciprocating lifting and lowering movements through the two sets of first electromagnets 66 and first fixed magnets 67 in the positioning state. The horizontal plates 72 drive the turning frame 73 and soil guides 74 to achieve a reciprocating insertion and turning effect on the shallow soil around the apple tree. A second circuit breaker 75 is fixedly connected to one side of the frame 1, and a second electromagnet 76 controlled by the opening and closing of the second circuit breaker 75 is embedded on the side of the frame 1 close to the soil guide 74. The bottom of the second electromagnet 76 is electromagnetically attracted by a second fixed magnet 77 fixedly matched with the horizontal plate 72. The second circuit breaker 75 controls the second electromagnet 76 to release the electromagnetic attraction measure of the second fixed magnet 77 on the horizontal plate 72 until the shallow turning work before the soil improvement operation around the apple tree is completed;

[0046] The outer side of the side frame 3 is vertically provided with a slide groove 11 fixedly matched with the slide 64, which plays a role of sliding limit for the slide 64, thereby improving the lifting and sliding stability of the slide 64, and the outer side of the frame 1 is fixedly connected with a slide sleeve 12 that slides with the light rod 71. The light rod 71 is provided with a compression spring 13, which plays a role of sliding support for the light rod 71, and also elastically buffers the lifting and lowering stroke of the light rod 71. The turning frame 73 is distributed in an array in a staggered state along the horizontal axis of the cross plate 72, and effectively interweaves and turns the shallow soil around the apple tree to make it fully turned over, and the turning frame 73 is fixedly connected with soil guide cones from top to bottom in sequence, and soil guide parts 74 are staggered to guide the soil during the turning process, thereby improving the turning effectiveness of the shallow soil.

[0047] The liquid feeding assembly also includes push-pull rods 81 fixed on both sides of the top of the cross frame 63, and the top of the push-pull rods 81 is fixedly connected to a piston head 82 that slides with the cylinder barrel 4. The cross frame 63 with a reciprocating lifting action drives the piston heads 82 on the two push-pull rods 81 to reciprocate in the two groups of cylinder barrels 4. A four-way valve 83 is connected to the cylinder barrel 4, and the liquid feeding port of the four-way valve 83 is connected to a liquid feeding pipe 84. The bottom end of the liquid feeding pipe 84 passes through the pot cover 87 on the liquid storage pot 86 and is connected to a flow equalizing head 85. The two reciprocating working The piston head 82 pressurizes the improver in the two groups of liquid storage pots 86 and supplies it to the two pressurized pipes 14 through the liquid supply pipes 84 and the flow equalizing head 85 on the two four-way valves 83. The discharge port of the four-way valve 83 is connected to the pressurized pipe 14 that penetrates and cooperates with the frame 1, and the bottom end of the pressurized pipe 14 is connected to the spray rack 15, and the array is connected to the spray head 16. The improver is evenly sprayed from the spray rack 15 on the pressurized pipe 14 through the spray head 16 into the shallow soil after turning over, completing the improvement work of the improver on the shallow soil.

[0048] The soil drilling assembly also includes a slave gear 92 arranged on the outside of the main gear 91, and an electric push rod 93 is fixedly connected to the top of the slave gear 92. The top of the electric push rod 93 is fixedly connected to a rotating shaft 94 that rotates with the side cover 5, and a main synchronous wheel 95 is fixedly connected to the rotating shaft 94. After the electric push rod 93 adjusts the meshing stroke between the main gear 91 and the slave gear 92 to a certain position, the double-headed motor 61 drives the main synchronous wheel 95 on the rotating shaft 94 to rotate through the meshed main gear 91 and the slave gear 92. The outer side of the main synchronous wheel 95 is connected to the slave synchronous wheel 96 through a synchronous belt transmission, and a soil drilling rod 97 used in conjunction with the frame 1 is provided at the bottom of the slave synchronous wheel 96. The main synchronous wheel 95 drives the three groups of soil drilling rods 97 on the slave synchronous wheels 96 to rotate accordingly through the synchronous belt, and the three three-stage cylinders 17 are used to lift and lower the height of the three soil drilling rods 97, so as to perform drilling operations on the deep soil around the apple tree and reduce damage to the roots of the apple tree deep in the soil.

[0049] A three-stage cylinder 17 is fixedly connected to the inner cavity of the synchronous wheel 96 and is coordinated with the side cover 5 for rotation. It is used for controlling the lifting and lowering of the drilling rod 97, so that the drilling rod 97 rotates while moving downward, and a drilling head 18 is fixedly connected to the bottom of the drilling rod 97 to improve the drilling efficiency of the drilling rod 97. A retaining cover 19 is embedded on the side of the frame 1 close to the drilling rod 97, and a cleaning port is opened on the outside of the retaining cover 19 to block the splashing soil generated during the drilling of the drilling rod 97.

[0050] like Figure 13-14 As shown, during the deep improvement of the soil around the apple tree, the improver cannot be added synchronously, and the rapid improvement effect of the deep soil around the apple tree cannot be achieved. The improver needs to be added separately, which is time-consuming and labor-intensive. The outer side of the liquid feeding component is provided with a liquid injection component used in conjunction with the soil drilling component, and the liquid injection component includes a connecting pipe 105 fixed on the three-stage cylinder 17, and the outer end of the connecting pipe 105 is rotatably connected to the manifold frame 104 and maintains a state of mutual communication with each other, and the outer end of the four-way valve 83 and the manifold frame 104 are connected to a connecting head 101, and the outer end of the connecting head 101 is rotatably connected to a rotating head 102 and maintains a state of mutual communication with each other. The improver in the two four-way valves 83 passes through the two connecting heads 101, the rotating head 102 and the telescopic tube 103 in sequence to reach the manifold frame 104. A hollow cavity 106 fixedly matched with the connecting tube 105 is provided in the soil drilling rod 97 and they maintain a state of mutual communication, and a liquid injection port 107 is provided on the outside of the soil drilling rod 97. The improver is then supplied into the hollow cavity 106 in the three soil drilling rods 97 through the connecting tube 105 and sprayed into the drill hole in the deep soil through the liquid injection port 107, thereby completing the improvement of the deep soil around the apple tree.

[0051] The working principle of a local soil improvement device for an apple orchard is as follows: First, the driving motor controls the Mecanum wheels 2 to drive the frame 1 to move in a circular motion around the soil surrounding the apple tree. When shallow soil improvement is required around the current apple tree, the two sets of first circuit breakers 65 are controlled to energize the two sets of first electromagnets 66. After the power is energized, the two sets of first electromagnets 66 use the two sets of first fixed magnets 67 to electromagnetically attract and position the two light rods 71. The second circuit breaker 75 is controlled to de-energize the second electromagnet 76, causing the second electromagnet 76 to lose the electromagnetic attraction force of the second fixed magnet 77, thereby releasing the initial positioning state of the horizontal plate 72. After the state is reached, the double-headed motor 61 is controlled to start and drive the cam 62 to rotate. The cam 62 drives the cross frame 63 to perform a reciprocating lifting movement. The cross frame 63 drives the two sets of slides 64 to slide back and forth in the slide groove 11. The two sets of slides 64 drive the two polished rods 71 to slide back and forth in the sliding sleeve 12 through the two sets of first electromagnets 66 and first fixed magnets 67 in the positioning state. With the two compression springs 13 acting as elastic buffers for the polished rods 71, the two polished rods 71 drive the turning frame 73 and the soil guide 74 through the cross plate 72 to perform a reciprocating interlaced turning operation on the shallow soil around the apple tree.

[0052] At the same time, the reciprocating lifting cross frame 63 drives the piston heads 82 on the two push-pull rods 81 to perform reciprocating work in the two cylinder barrels 4, and then the improver pre-filled in the two sets of liquid storage pots 86 is supplied to the two pressurized pipes 14 through the liquid supply pipe 84 on the two four-way valves 83 after being processed by the equalizing head 85, and the manifold frame 104 is in a closed state. If there is no improver, the pot cover 87 can be directly screwed open to replenish the liquid storage pot 86. The improver is then evenly sprayed to the shallow soil area after the interspersed turning and throwing operation through the spray head 16 on the spray frame 15, completing the improvement of the shallow soil around the apple tree.

[0053] When it is necessary to deeply improve the soil around the current apple tree, first control the two groups of first circuit breakers 65 to cut off the power to the two groups of first electromagnets 66. After the power is cut off, the two groups of first electromagnets 66 lose the electromagnetic attraction force on the two groups of first fixed magnets 67, and the initial positioning state of the two light rods 71 is released. Then control the second circuit breaker 75 to energize the second electromagnet 76, and control the second electromagnet 76 to electromagnetically attract the horizontal plate 72 on the second fixed magnet 77. After the initial positioning state of the horizontal plate 72 is completed, first control the electric push rod 93 to open and drive the gear 92 to move down to the meshing part of the main gear 91, and then control the double-headed motor 61 to open. The main gear 91 is then engaged and drives the slave gear 92 to rotate. The slave gear 92 drives the main synchronous wheel 95 to rotate via the rotating shaft 94. The main synchronous wheel 95 drives the three sets of three-stage cylinders 17 on the slave synchronous wheels 96 to rotate synchronously via the timing belt. The three three-stage cylinders 17 then drive the three drilling rods 97 and the drilling head 18 to rotate. During this period, the three three-stage cylinders 17 raise and lower the drilling depth of the three drilling rods 97. The three rotating drilling rods 97, in coordination with the three three-stage cylinders 17, drill holes in the deep soil around the apple tree.

[0054] At the same time, the reciprocating lifting and lowering cross frame 63 drives the piston heads 82 on the two push-pull rods 81 to perform reciprocating work in the two cylinder barrels 4, and does not make any lifting and lowering movements on the two bare rods 71. Similarly, the two pressurized pipes 14 are in a closed state, and the improver pre-filled in the two sets of liquid storage pots 86 is supplied into the manifold frame 104 through the two four-way valves 83 in sequence through the two connecting heads 101, the rotating head 102 and the telescopic tube 103. The improver arriving in the manifold frame 104 is supplied into the hollow cavity 106 through the connecting pipe 105 that rotates with the drilling rod 97, and then sprayed into the deep soil where the hole is drilled through the liquid injection port 107. After completing the improvement of the deep soil around the apple tree, the double-headed motor 61 is first controlled to be closed, and then the electric push rod 93 is controlled to be closed and drive the slave gear 92 to move up and disengage from the meshing part of the main gear 91 to the initial position.

[0055] It should be noted that the specific models and specifications of the double-headed motor 61, circuit breaker, electric push rod 93, three-stage cylinder 17 and various valves need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0056] The power supply circuits of the double-headed motor 61, the circuit breaker, the electric push rod 93, the three-stage cylinder 17 and various valves are clear to those skilled in the art and will not be described in detail here.

[0057] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
