[0002] In modern agricultural production, poplars play an important role in forestry, urban greening and papermaking industries due to their rapid growth, strong adaptability and wide range of uses. In the process of poplar planting, soil tillage is a key link, which can improve soil structure, increase soil aeration and water permeability, and help control weeds and pests.
[0003] Rotary tillers are important tools for tilling the soil. Traditional rotary tillers mainly have multiple blade seats welded on the blade shaft, and then the rotary tiller blades are inserted into the blade seats and fixed by bolts to rotate the blade shaft, which drives the blades to rotate, so that the blades enter the soil to complete the rotary tillage. Because some soils are compacted, the initial resistance of the blades entering the soil is large, resulting in higher requirements for power input. In addition, some soils are heavy and a large amount of soil is easily adhered to the blades. If it cannot be removed in time, the subsequent resistance of the blades entering the soil is further increased.

[0025] The connecting member includes two conductive blocks 9 fixedly connected to the first rotating shaft 3, and an insulating gasket is arranged between the two conductive blocks 9. The electromagnet 11 is connected in series between the two conductive blocks 9. When the conductive block 9 is in the first connection section 31 or the second connection section 32, one conductive block 9 is in sliding contact with the first conductive sheet 23, and the other conductive block 9 is in sliding contact with the second conductive sheet 24.

When the conductive block 9 is in the first commutation section 29 and the second commutation section 30, the electromagnet 11 is in a power-off state.
[0026] In this embodiment, the plows are arranged in groups, namely, the first plow group and the second plow group. The first plow group and the second plow group each have a plurality of plows, and the first plow group and the second plow group are arranged at intervals. The first plow group includes two first plows 4, and the second plow group includes two second plows 25. The first plow 4 and the second plow 25 are arranged vertically. The cover body 1 is fixedly connected with a connecting plate 5 and a connecting shell 26. The connecting plate 5 and the connecting shell 26 are both provided with a power connection assembly, and each power connection assembly includes two connecting parts. The power connection assembly in the connecting plate 5 cooperates with the first plow group, and the two first plows 4 in the first plow group correspond one-to-one to the two connecting parts located in the connecting plate 5. The electromagnet 11 corresponding to the first plow 4 is connected to the corresponding connecting part in the connecting plate 5. The power connection assembly in the connecting shell 26 cooperates with the second plow group, and the two second plows 25 in the second plow group correspond one-to-one to the two connecting parts located in the connecting shell 26. The electromagnet 11 corresponding to the second plow 25 is connected to the corresponding connecting part in the connecting shell 26.
[0027] Working principle: The device is connected to the tractor through the connecting frame 2 and installed on the tractor.
[0028] Initially, the conductive block 9 is in the first connection section 31, the electromagnet 11 and the magnetic block 17 are attracted together, and the spring 28 is in a compressed state.
[0029] When in use, the motor 7 is started, the first rotating shaft 3 rotates, and the plow blade rotates from above the ground to the direction close to the ground. The first rotating shaft 3 drives the conductive block 9 to rotate, and the conductive block 9 slides along the first connection section 31 to the first reversing section 29. When the plow blade is parallel to the ground and is about to contact the ground, the conductive block 9 moves to the first reversing section 29, and the conductive block 9 is separated from the first conductive sheet 23 and the second conductive sheet 24, and the electromagnet 11 is powered off. Under the action of the spring 28, the slider 18 slides quickly in the direction away from the electromagnet 11, and the plow blade speed increases, so that the plow blade rotates quickly toward the ground, and the plow blade quickly enters the soil, which is conducive to the plow blade entering the soil.
[0030] When the conductive block 9 moves from the first switching section 29 to the second connection section 32, due to the change in the direction of the current in the conductive block 9, the direction of the current in the electromagnet 11 changes, the electromagnet 11 repels the magnetic block 17, and the slider 18 has a force to move away from the electromagnet 11, which helps the plow blade to move into the soil.
[0031] When the conductive block 9 passes through the second switching section 30 from the second connection section 32 and enters the first connection section 31, the current direction in the conductive block 9 changes again, and the magnetic block 17 generates an attractive force on the electromagnet 11. At the same time, under the resistance of the soil, the slider 18 slides toward the electromagnet 11 until the magnetic block 17 and the electromagnet 11 are attracted together.
[0032] Then, as the first rotating shaft 3 rotates, the plow blade gradually moves onto the ground. When the plow blade comes out of the ground, soil may be stuck to it.
[0033] As the first rotating shaft 3 rotates, the conductive block 9 slides along the first connection section 31, and the magnetic block 17 and the electromagnet 11 remain adsorbed together. When the first coulter 4 is about to contact the ground again, the conductive block 9 enters the first reversing section 29, and under the action of the spring 28, the slider 18 quickly enters the soil. The rotation speed of the slider 18 suddenly increases, which can shake the soil off the coulter. This helps to reduce the resistance of the coulter when entering the soil, which is beneficial to improving the stability of the equipment operation.
[0034] Embodiment 2: This embodiment is an improvement based on embodiment 1.
[0035] The connecting shaft 16 is rotatably mounted on the slider 18, so that the connecting shaft 16 rotates, thereby changing the bending direction of the coulter and thus changing the tillage mode.
[0036] The first rotating shaft 3 is provided with a driving mechanism for driving the connecting shaft 16 to rotate. The driving mechanism includes a second rotating shaft 8 and a transmission assembly. The first rotating shaft 3 has a hollow structure. The second rotating shaft 8 is arranged inside the first rotating shaft 3, and the second rotating shaft 8 and the first rotating shaft 3 are arranged coaxially. The second rotating shaft 8 moves along the axial direction of the first rotating shaft 3, and an electric push rod 27 is fixedly installed at one end of the first rotating shaft 3, and the telescopic end of the electric push rod 27 is fixedly connected to one end of the second rotating shaft 8. The transmission assembly is arranged between the second rotating shaft 8 and the connecting shaft 16. When the second rotating shaft 8 moves axially along the first rotating shaft 3, the connecting shaft 16 rotates under the action of the transmission assembly.
[0037] The transmission assembly includes a rack 22, a gear 14, a worm 13 and a worm wheel 15. One end of the connecting shaft 16 passes through the slide slot 21 and extends into the first rotating shaft 3, and the end of the connecting shaft 16 extending into the first rotating shaft 3 is fixedly connected to the worm wheel 15. The connecting shaft 16 is rotatably connected to the connecting block 12, and the connecting block 12 is slidably connected to the inner wall of the first rotating shaft 3. The worm 13 is rotatably set on the connecting block 12, and the worm 13 is coaxially fixedly connected to the gear 14. A rack 22 that cooperates with the gear 14 is fixedly connected to the circumferential surface of the second rotating shaft 8. The worm 13 and the worm wheel 15 are meshed. There are multiple racks 22, and the racks 22 cooperate with the corresponding gears 14.
[0038] Working principle: When the tillage mode needs to be adjusted, the electric push rod 27 is started, and the electric push rod 27 drives the second rotating shaft 8 to move along the axial direction of the first rotating shaft 3, and the rack 22 moves, so that the rack 22 is engaged with the corresponding gear 14, the gear 14 rotates, the worm 13 rotates, the worm wheel 15 and the connecting shaft 16 rotate, and then the plow blade rotates, changing the bending direction of the plow blade, and then adjusting the tillage mode.
[0039] In this embodiment, the installation methods of the plow are divided into three types according to the bending direction of the plow.
[0040] First, the internal installation method is to make the bending directions of all the plow blades face the center, the axial force on the first rotating shaft 3 is symmetrical, there is no missing plowing between the plow blades after plowing, but ridges are formed in the middle of the plowing width, which is suitable for split-row cultivation.
[0041] Second, the external installation method, the bending direction of all the plow blades is back to the center, the axial force on the first rotating shaft 3 is also symmetrical, there is no missing plowing between the plow blades after ploughing, but the middle of the plowing width is formed into a furrow, and the two ends are formed into ridges, which is suitable for the combined operation of furrow demolition and rotary tillage.
[0042] Third, the staggered method, the left and right coulters are staggered and symmetrically installed on the first rotating shaft 3, and the surface is flat after plowing, but there is leakage of plowing at the opposite directions of adjacent coulters. It is suitable for rotary tillage after plowing or rotary tillage of stubble land.
[0043] The length of the rack 22 can be set so that the plow blade can be rotated to different angles, thereby making the bending direction of the plow blade different.
[0044] For example, the rack 22 can be set to two groups, namely the first rack group and the second rack group. Initially, the plow is in the internal installation state. When the plow needs to be in the external installation state, the second rotating shaft 8 is moved to make the first rack group mesh with the gear 14. Under the action of the first rack group, the connecting shaft 16 rotates 180 degrees, thereby putting the plow in the external installation state. The second rack group is meshed with the gear 14, and by reasonably setting multiple racks 22 in the first rack group, the multiple connecting shafts 16 are rotated by corresponding angles, thereby putting multiple plows in the staggered installation state.
[0045] When the rack 22 is disengaged from the gear 14 , the connecting shaft 16 will not rotate accidentally due to the self-locking property of the worm 13 and the worm wheel 15 .
[0046] The present invention also includes a method for using the poplar planting soil tillage device, comprising the following steps: S1, connecting the connecting frame 2 to the tractor; S2, the electromagnet 11 and the magnetic block 17 attract each other, the conductive block 9 is in the first connection section 31, so that the first rotating shaft 3 rotates, and the coulter rotates. When the coulter is about to contact the ground, the conductive block 9 is separated from the first connection section 31, and the slider 18 drives the coulter to quickly go down into the soil; S3, when the conductive block 9 is in the second connection section 32, the electromagnet 11 repels the magnetic block 17; S4, when the conductive block 9 is separated from the second connection section 32 and is in the first connection section 31, the magnetic block 17 and the electromagnet 11 are attracted to each other, and the slider 18 slides along the connecting seat 10 until the magnetic block 17 and the electromagnet 11 are attracted together; S5. When adjusting the tillage mode, the electric push rod 27 drives the second rotating shaft 8 to move. Under the action of the driving mechanism, the connecting shaft 16 rotates, and the connecting shaft 16 drives the coulter to rotate, thereby changing the bending direction of the coulter.
[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
