[0017] The machine body 1 is driven to move by the movement of the roller 2, and the machine body 1 drives the mounting seat 3, the connecting rod 4 and the furrow opener 5 to move, and the fixing seat 6 and the connecting rod 4 are moved, and the moving wheel 7 is connected to the fixing seat 6 through the first connecting block 8, so that when the connecting rod 4 drives the fixing seat 6 to move, the moving wheel 7 moves, so that the first furrowing knife 9 opens furrows, and when encountering an area with relatively hard land, the first electric push rod 12 is started to drive the first moving block 11 to move upward, so that the first furrowing knife 9 moves upward and away from the ground, and when the first moving block 11 moves, it drives the first rack 13 to move, so that the gear 14 drives the rotating shaft to rotate along the inner wall of the fixing seat 6, so that the second rack 15 drives the second moving block 11 to move downward, and the second moving block 11 drives the second furrowing knife 10 to move downward and contact the ground, and then the machine body 1 is driven to move by the movement of the roller 2, so that the mounting seat 3, the connecting rod 4 and the fixing seat 6 move, and the fixing seat 6 drives the moving wheel 7 to move, so that the second furrowing knife 10 moves to loosen the soil in advance, and after the treatment is completed, the first The electric push rod 12 drives the first moving block 11 and the first furrowing knife 9 to move downward, and through the action of the first rack 13, the gear 14 and the second rack 15, the second moving block 11 drives the first furrowing knife 9 to move upward. When the first furrowing knife 9 moves to the ground, the second furrowing knife 10 moves to its original position, and then the second furrowing knife 10 furrows the area after loosening the soil, thereby reducing the working difficulty of the furrowing device 5 and reducing the loss of the machine. At the same time, it can also ensure the quality of furrowing, make the shape of the furrow more regular, and facilitate improving the furrowing effect. Through the movement of the adjusting device 17 at the second furrowing knife 10, the adjusting device 17 is moved to the inside of the second mounting groove, so that the second furrowing knife 10 can maintain the same width as the first furrowing knife 9 to loosen the soil in advance. After loosening the soil, the adjusting device 17 on the inner wall of the first mounting groove and the second mounting groove moves, which can adjust the width of the first furrowing knife 9 and the second furrowing knife 10, so as to open furrows of different widths and adapt to the width of sowing in different middle parts, thereby facilitating use.

[0018] like Figures 2 to 4 As shown, the furrowing knife 5 is located between the rollers 2. There are five furrowing knifes 5, and they are distributed in a linear array with the connecting rod 4 as the center. The second furrowing knife 10 is located between the first furrowing knife 9 and the moving wheel 7. The first furrowing knife 9 is located below the second furrowing knife 10. A fixing structure 18 is provided at one end of the first furrowing knife 9 close to the fixing seat 6.

[0019] Through the five furrow openers 5 in a linear array, furrows can be opened multiple times at one time, which is convenient for improving the efficiency of furrowing and the efficiency of sowing. Since the second furrowing knife 10 is located between the first furrowing knife 9 and the movable wheel 7, when the first furrowing knife 9 moves to open furrows, the second furrowing knife 10 blocks one side of the movable wheel 7 to prevent the first furrowing knife 9 from causing soil to accumulate on the movable wheel 7 when opening furrows, thereby affecting the movement of the movable wheel 7 and making it inconvenient for the furrow opener 5 to open furrows. The fixing structure 18 facilitates the connection between the first furrowing knife 9 and the fixed seat 6 to improve the stability of the first furrowing knife 9. At the same time, the mobile fixing structure 18 can separate the first furrowing knife 9 from the fixed seat 6, which is convenient for replacing the damaged first furrowing knife 9, thereby improving the furrowing effect of the first furrowing knife 9.

[0020] like Figures 4 to 5 As shown, one side of the first movable block 11 is slidably connected to the inner wall of the fixed seat 6, and the first telescopic rods 19 are fixedly installed at both ends of the top of the second movable block 16. The top of the first telescopic rod 19 is fixedly installed to the top inner wall of the fixed seat 6. A movable groove is opened at the bottom of the fixed seat 6, and the movable groove is communicated with the interior of the fixed seat 6. A movable opening is opened on one side of the movable groove and located at the bottom of the fixed seat 6. One end of the first grooving knife 9 is located inside the movable groove, and one end of the second grooving knife 10 extends through the movable opening to the inside of the fixed seat 6.

[0021] When the first electric push rod 12 contracts and drives the first moving block 11 to move, the first moving block 11 moves upward along the inner wall of the fixed seat 6, thereby improving the stability of the first moving block 11 driving the first ditching knife 9 to move, and at the same time, one end of the first ditching knife 9 moves from the inside of the moving groove to the inside of the fixed seat 6, so that the other end of the first ditching knife 9 is separated from the ground, and then through the action of the first rack 13, the gear 14 and the second rack 15, the second moving block 16 moves downward along the inner wall of the fixed seat 6, so that one end of the second ditching knife 10 moves from the inner wall of the fixed seat 6 to the moving port, and the other end moves to the ground, so that before the first ditching knife 9 digs the trench, the second ditching knife 10 can be used to loosen the soil in advance, thereby reducing the loss of the machine, and at the same time ensuring the quality of the trenching, making the shape of the trench more regular, and facilitating improving the trenching effect.

[0022] like Figures 5 to 7 As shown, the adjusting device 17 includes a motor 171, the output end of the motor 171 is transmission-connected with a threaded rod 172, one end of the threaded rod 172 is rotatably connected with a limiting plate 173, one end of the threaded rod 172 is threadedly connected with a movable plate 174, one side of the movable plate 174 is slidably connected to the inner walls of the first mounting groove and the second mounting groove, both ends of the movable plate 174 are hinged with a rotating plate 175, one end of the rotating plate 175 is hinged with a slider 176, one side of the slider 176 is slidably connected to the first mounting groove and the second mounting groove, and an adjusting knife 177 is fixedly installed on one side of the slider 176.

[0023] When the width of the furrowing needs to be adjusted, the starting motor 171 drives the threaded rod 172 to rotate along the limiting plate 173, so that the movable plate 174 moves along the threaded rod 172, and the rotating plate 175 deflects to push the slider 176 to move, so that the slider 176 pushes the adjusting knife 177 to move to both sides of the first furrowing knife 9, thereby increasing the width of the first furrowing knife 9, thereby facilitating adaptation to the sowing width of different seeds and improving the comprehensiveness of sowing.

[0024] like Figures 5 to 7 As shown, the motor 171 and the limiting plate 173 are fixedly installed on the inner walls of the first mounting groove and the second mounting groove, the rotating plate 175, the sliding block 176 and the adjusting knife 177 are symmetrically arranged with the movable plate 174 as the center, and a second connecting block 20 is arranged between the bottom ends of the two adjusting knives 177. The bottom of the second connecting block 20 is fixedly installed on the inner walls of the first mounting groove and the second mounting groove, and movable grooves are provided on both sides of the second connecting block 20. A limiting block 21 is slidably connected inside the movable groove, and one side of the limiting block 21 is fixedly installed with the adjusting knife 177. The adjusting knife 177 inside the first mounting groove is located inside the first mounting groove, the movable plate 174 inside the first mounting groove is located at one end of the threaded rod 172 close to the motor 171, the limiting block 21 in the first mounting groove is located inside the movable groove, and the adjusting knife 177 at the second mounting groove is located on both sides of the second grooving knife 10, the movable plate 174 inside the second mounting groove is located on one side of the limiting plate 173, and the limiting blocks 21 inside the second mounting groove are located on both sides of the second connecting block 20.

[0025] The symmetrically arranged rotating plate 175, slider 176 and adjusting knife 177 facilitate the adjusting knife 177 to move to both sides of the first trenching knife 9 and the second trenching knife 10 at the same time. Since the adjusting knife 177 inside the first installation groove is located inside the first installation groove, when the adjusting knife 177 inside the first installation groove moves, it can drive the limiting block 21 to move out of the movable groove, thereby facilitating the limiting of the adjusting knife 177 and improving the stability of the adjusting knife 177 after movement. By increasing the width of the first trenching knife 9 and the second trenching knife 10 by adjusting the knife 177, The machine body 1 is moved to open trenches of different widths, thereby facilitating the use of the trench opener 5. Since the adjusting knife 177 at the second mounting groove is located on both sides of the second trench opening knife 10, when the first trench opening knife 9 is trenching, the adjusting knife 177 and the second trench opening knife 10 can block one side of the moving wheel 7 to prevent the first trench opening knife 9 from causing soil to accumulate on the moving wheel 7 when trenching, thereby affecting the movement of the moving wheel 7 and making it inconvenient for the trench opener 5 to trench.

[0026] like Figures 8 to 9As shown, the fixed structure 18 includes a fixed rod 181, both ends of the fixed rod 181 are movably connected with an insertion rod 182, both ends of the insertion rod 182 are provided with a fixed plate 183, one side of the fixed plate 183 is provided with a groove, one end of the insertion rod 182 is plugged into the groove, a plug hole is provided on the front side of the fixed plate 183, the plug hole passes through one end of the insertion rod 182, a second electric push rod 184 is fixedly installed inside the plug hole, one end of the second electric push rod 184 is plugged into one end of the insertion rod 182, a second telescopic rod 185 is fixedly installed on the top of the fixed plate 183, the second telescopic rod 185 passes through the moving groove and is fixedly installed on the bottom of the first moving block 11, the first grooving knife 9 is provided with a mounting hole near one end of the groove, the fixed rod 181 is fixedly installed on the first grooving knife 9 through the mounting hole, the top of the fixed plate 183 is in contact with the bottom of the fixed seat 6, and the fixed plate 183 is located at the bottom of the groove.

[0027] The fixing rod 181 is connected to the first trenching knife 9 through the mounting hole, and the second electric push rod 184 is plugged into the grooves on both sides of the fixing plate 183 through the plugging rod 182, so that the stability of the first trenching knife 9 is improved. When the first moving block 11 moves, it drives the first trenching knife 9 to move upward, so that the second telescopic rod 185 contracts, thereby moving the fixing plate 183 and the fixing rod 181 upward to the inside of the groove at the same time, so that the second trenching knife 10 moves upward and separates from the ground, which is convenient for the second trenching knife 10 to loosen the soil, reduce the wear of the first trenching knife 9, and improve the stability of the first trenching knife 9. The service life of a trenching knife 9 is extended. When the first trenching knife 9 needs to be disassembled, the second electric push rod 184 is started to retract into the inside of the socket, and one end of the second electric push rod 184 is separated from one end of the insertion rod 182, and then the insertion rod 182 is moved to both ends of the fixed rod 181, so that the insertion rod 182 is separated from the groove, and the first trenching knife 9 is separated from the fixed plate 183, and then the first trenching knife 9 is moved downward to separate the first trenching knife 9 from the first electric push rod 12, so that the first trenching knife 9 is no longer connected to the fixed seat 6, which is convenient for replacing the first trenching knife 9 and improving the trenching effect of the trencher 5.

[0028] Working principle: When in use, the roller 2 moves to drive the machine body 1 to move, and the machine body 1 drives the mounting seat 3, the connecting rod 4 and the furrow opener 5 to move, and the fixing seat 6 and the connecting rod 4 move, and the moving wheel 7 is connected to the fixing seat 6 through the first connecting block 8, so that when the connecting rod 4 drives the fixing seat 6 to move, the moving wheel 7 moves, so that the first furrowing knife 9 performs furrowing. When encountering an area with relatively hard land, the first electric push rod 12 is started to drive the first moving block 11 to move upward, so that the first furrowing knife 9 drives the fixing rod 181 and the fixing plate 183 to move upward, so that the second telescopic rod 185 contracts, and when the fixing plate 183 and one end of the first furrowing knife 9 move to the moving When the first groove is inside, the other end of the first trenching knife 9 moves upward and away from the ground. When the first moving block 11 moves, it drives the first rack 13 to move, so that the gear 14 drives the rotating shaft to rotate along the inner wall of the fixed seat 6, so that the second rack 15 drives the second moving block 11 to move downward, and the second moving block 11 drives the second trenching knife 10 to move downward and contact the ground, and then the motor 171 drives the threaded rod 172 to rotate along the limiting plate 173, so that the movable plate 174 moves along the threaded rod 172, and the rotating plate 175 is deflected to drive the slider 176 to move along the inner wall of the second installation groove, so that the adjusting knife 177 moves to the inside of the second installation groove, and then the belt is moved by the roller 2 The machine body 1 moves, so that the mounting seat 3, the connecting rod 4 and the fixed seat 6 move, and the fixed seat 6 drives the moving wheel 7 to move, so that the second trenching knife 10 moves to loosen the soil in advance. After the treatment is completed, the first electric push rod 12 drives the first moving block 11 and the first trenching knife 9 to move downward, and through the action of the first rack 13, the gear 14 and the second rack 15, the second moving block 11 drives the trenching knife to move upward. When the first trenching knife 9 moves to the ground, the second trenching knife 10 moves to the original position, and then the second trenching knife 10 trenches the area after loosening the soil. When the machine body 1 needs to open trenches of different widths, the motor 1 on the inner wall of the first mounting groove is started 71, so that the motor 171 drives the threaded rod 172 to rotate along the limiting plate 173, so that the movable plate 174 moves and drives the rotating plate 175 to deflect, so that the slider 176 drives the adjusting knife 177 to move, and the adjusting knife 177 drives the limiting block 21 to move out of the moving groove, so that the adjusting knife 177 moves to both sides of the first furrowing knife 9, increases the width of the first furrowing knife 9, and then increases the width of the second furrowing knife 10 through the adjusting knives 177 on both sides of the second furrowing knife 10. After the second furrowing knife 10 with increased width loosens the ground, the machine body 1 moves again, so that the first furrowing knife 9 with increased width can furrow, so as to adapt to the sowing width of different seeds.

[0029] When the first trenching knife 9 needs to be replaced, the second electric push rod 184 is started to retract into the inside of the socket, and one end of the second electric push rod 184 is separated from one end of the insertion rod 182, and then the insertion rod 182 is moved toward the fixed rod 181, so that the insertion rod 182 is separated from the groove, and the first trenching knife 9 is separated from the fixed plate 183, and then the first trenching knife 9 is moved downward to separate the first trenching knife 9 from the first electric push rod 12, so that the first trenching knife 9 is no longer connected to the fixed seat 6, which facilitates the replacement of the first trenching knife 9 and improves the trenching effect of the trench opener 5.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
