[0017] The beneficial effects of the present invention are as follows: 1. In the present invention, when the output end of the fifth electric telescopic rod extends, it drives the second rotating shaft to slide on the inner surface of the arc-shaped groove. The second rotating shaft drives the first connecting ear to move. At the same time, the second connecting ear rotates on the outer surface of the third rotating shaft.

[0018] 2. In the present invention, the first electric telescopic rod drives the first mounting plate to a horizontal state, so that the ultrasonic detector can detect the stones in the soil.

[0019] 3. In the present invention, the output shaft of the second motor drives the second pulley to rotate through the first belt drive. The second pulley located at the bottom can drive the crushing roller to rotate, thereby crushing the turned-up soil. The height of the crushing roller can be adjusted by the sixth electric telescopic rod. When the second motor is started, the output shaft of the second motor will also drive the third pulley to rotate. Through the second belt drive, the first pulley also starts to rotate. The first pulley drives the turntable to rotate through the first rotating shaft. The turntable further drives the first connecting rod to rotate. The first connecting rod is connected to the rotating rod and causes the rotating rod to drive the second sliding rod to perform up-and-down reciprocating motion. The second sliding rod further drives the leakage frame to perform reciprocating motion. This can cause the soil blocks wrapped with stones in the inner cavity of the leakage frame to scatter, and the soil will leak out from the bottom of the leakage frame, while the stones still remain in the inner cavity of the leakage frame. In order to enable the second belt to continuously drive the third pulley and the first pulley, the spring rod supports the fixed block and the fourth pulley, which can keep the second belt always tight and achieve the drive.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 7As shown in the figure, a tillage soil-turning machine includes an installation cavity 1. A first mounting plate 21 is rotatably installed at the top of the installation cavity 1. A plurality of ultrasonic detectors 22 are fixedly installed at the bottom of the first mounting plate 21. Two plows 42 are movably installed in the inner cavity of the installation cavity 1. It further includes a cleaning mechanism for cleaning stones in the soil. The cleaning mechanism includes a first sliding rod 25. The first sliding rod 25 is slidably installed on the inner wall of the installation cavity 1. A first connecting block 254 is slidably installed in the inner wall of the first sliding rod 25. A third electric telescopic rod 255 is fixedly installed at the top of the first connecting block 254. The output end of the third electric telescopic rod 255 is fixedly connected to a second connecting block 256 and a fourth electric telescopic rod 26. Two third connecting blocks 257 are rotatably installed at the bottom of the second connecting block 256. A bucket 258 is fixedly connected to the bottom of the third connecting block 257. The output end of the fourth electric telescopic rod 26 is fixedly connected to a second mounting plate 261. Two limiting columns 262 are fixedly installed on one side of the second mounting plate 261. A limiting groove 2571 is formed on one side of the third connecting block 257. The limiting columns 262 are slidably installed on the inner surface of the limiting groove 2571.

[0025] When using a soil-turning machine for tillage, there will be stones in the cultivated land. When the soil-turning machine passes by, it will damage the parts on the soil-turning machine. Therefore, it is necessary to clean the stones in the soil before the soil-turning machine passes by.

[0026] When the present invention is in use, first, the first mounting plate 21 drives the ultrasonic detector 22 to rotate to the horizontal position. When the soil-turning machine moves forward, the ultrasonic detector 22 detects the stones in the soil. A plurality of ultrasonic detectors 22 can detect an area in front of the soil-turning machine before soil turning, and a plurality of ultrasonic detectors 22 can respectively detect the stones in the area below themselves. The ultrasonic detector 22 integrates a logic processing module and can directly output control instructions, which can replace a simple controller. Therefore, the ultrasonic detector 22 can drive the electronic components in the soil-turning machine to start and close. Then, the first connecting block 254 slides in the inner cavity of the first sliding rod 25. The first connecting block 254 drives the second connecting block 256 and the fourth electric telescopic rod 26 to move to the position where the stone is detected. The output end of the third electric telescopic rod 255 extends to make the bucket 258 contact the ground. At the same time, the output end of the fourth electric telescopic rod 26 also extends. The output end of the fourth electric telescopic rod 26 drives the two limiting columns 262 to slide along the inner surface of the limiting groove 2571. At this time, the two buckets 258 approach each other and shovel up the soil on the ground, and the stones will be shoveled up together with the soil. Then, the output end of the third electric telescopic rod 255 contracts, and the two combined buckets 258 can be retracted to complete the cleaning of the stones.

[0027] Further, as Figure 2As shown, two first support blocks 2 are fixedly installed at the top of the installation cavity 1. The first mounting plate 21 is rotatably installed between the two first support blocks 2. Two first electric telescopic rods 23 are rotatably connected to the bottom of the first mounting plate 21. Two second support blocks 24 are fixedly installed at the top of the installation cavity 1. The two first electric telescopic rods 23 are respectively rotatably installed on the tops of the two second support blocks 24.

[0028] When the present invention is in use, the tilt angle of the first mounting plate 21 can be controlled by the extension and contraction of the output end of the first electric telescopic rod 23. During use, both ends of the first electric telescopic rod 23 rotate on the inner wall of the second support block 24 and the first mounting plate 21 respectively. By adjusting the angle of the first mounting plate 21, the distance between the ultrasonic detector 22 and the ground can be controlled, avoiding damage to the ultrasonic detector 22 when the distance between the ultrasonic detector 22 and the ground is too close or even in contact with the ground when encountering uneven ground.

[0029] Further, as Figure 2 shown, two first grooves 11 are formed on the outer surface of the installation cavity 1. The first sliding rod 25 is slidably installed on the inner surfaces of the two first grooves 11. Two second electric telescopic rods 251 are fixedly installed on one side of the first sliding rod 25. The second electric telescopic rods 251 are fixedly installed on the outer surface of the installation cavity 1; A threaded rod 253 is rotatably installed in the inner cavity of the first sliding rod 25. The threaded rod 253 is threadedly connected to the first connecting block 254. One side of the first sliding rod 25 is fixedly connected to a first motor 252. The output shaft of the first motor 252 is fixedly connected to one end of the threaded rod 253.

[0030] When the present invention is in use, the first sliding rod 25 is controlled to slide on the inner surfaces of the two first grooves 11 by the extension and contraction of the output ends of the two second electric telescopic rods 251. Further, the first sliding rod 25 drives the first connecting block 254 to move. At the same time, the output shaft of the first motor 252 drives the threaded rod 253 to rotate. The threaded rod 253 can drive the first connecting block 254 to slide in the inner cavity of the first sliding rod 25, so that the first connecting block 254 drives the two buckets 258 to move above the detected stones.

[0031] Further, as Figure 5 shown, two arc-shaped grooves 12 are formed on the inner wall of the installation cavity 1. A second rotating shaft 41 is slidably installed on the inner surfaces of the two arc-shaped grooves 12 together. A first connecting ear 421 and a second connecting ear 422 are fixedly installed on the outer surface of the plow 42. The first connecting ear 421 is rotatably installed on the outer surface of the second rotating shaft 41. A third rotating shaft 44 is rotatably and fixedly installed in the inner cavity of the installation cavity 1. The second connecting ear 422 is rotatably installed on the outer surface of the third rotating shaft 44; A fifth electric telescopic rod 4 is rotatably installed on the outer surface of the second rotating shaft 41. The fifth electric telescopic rod 4 is rotatably installed on the inner wall of the installation cavity 1. A second connecting rod 43 is rotatably installed on the outer surfaces of the second rotating shaft 41 and the third rotating shaft 44. The bottom of the second connecting rod 43 is rotatably connected to a runner 45.

[0032] When the present invention is in use, when plowing the land, the plow 42 needs to be lower than the runner 45. Therefore, during use, the output end of the fifth electric telescopic rod 4 extends to drive the second rotating shaft 41 to slide along the inner cavity of the arc-shaped groove 12. At this time, the first connecting ear 421 rotates on the outer surface of the second rotating shaft 41, and at the same time, the second connecting ear 422 rotates on the outer surface of the third rotating shaft 44. Under the action of the second connecting rod 43, one end of the second connecting rod 43 will drive the runner 45 to move upward, thereby achieving the purpose of moving the plow 42 downward. When not plowing, the runner 45 is lower than the plow 42, and the runner 45 can be rotated to move the tiller, and at the same time, it can prevent the plow 42 from contacting the ground.

[0033] Further, as Figure 6 shown, two second grooves 14 are formed on the outer surface of the installation cavity 1. A U-shaped mounting frame 5 is slidably installed on the inner surfaces of the two second grooves 14. Two sixth electric telescopic rods 51 are fixedly installed on the top of the U-shaped mounting frame 5. The sixth electric telescopic rods 51 are fixedly installed on the inner wall of the installation cavity 1. A crushing roller 55 is rotatably installed on the inner surface of the U-shaped mounting frame 5; Two second belt pulleys 52 are rotatably installed on one side of the U-shaped mounting frame 5. One end of the crushing roller 55 is fixedly connected to one side of the second belt pulley 52. The two second belt pulleys 52 are driven by a first belt 54. A second motor 53 is fixedly connected to one side of the second belt pulley 52. The second motor 53 is fixedly installed on one side of the U-shaped mounting frame 5. A handrail 13 is fixedly installed on one side of the installation cavity 1. A roller frame 15 is fixedly installed in the inner cavity of the installation cavity 1.

[0034] When the present invention is in use, after the soil is turned over, it is all soil blocks, and the soil can also be crushed. During use, the output shaft of the second motor 53 drives the second belt pulley 52 to rotate. After being driven by the first belt 54, both second belt pulleys 52 start to rotate. The second belt pulley 52 at the bottom can drive the crushing roller 55 to rotate, and the crushing roller 55 rotates to crush the soil blocks. At the same time, the height of the U-shaped mounting frame 5 can be adjusted by two sixth electric telescopic rods 51. When the sixth electric telescopic rods 51 extend and contract, the U-shaped mounting frame 5 slides on the inner surfaces of the two second grooves 14, and at the same time, the U-shaped mounting frame 5 drives the crushing roller 55 to move to achieve the purpose of adjusting the height of the crushing roller 55.

[0035] Further, as Figure 4 and Figure 7As shown, two fourth connection blocks 3 are fixedly installed inside the installation cavity 1. A second sliding rod 31 is slidably installed on the top of the fourth connection block 3. A leakage frame 32 is rotatably connected to the bottoms of the two second sliding rods 31. A rotating rod 311 is rotatably connected to the top of the second sliding rod 31. A first connecting rod 312 is rotatably connected to the opposite surfaces of the two rotating rods 311. One end of the first connecting rod 312 is rotatably connected to a turntable 313. The turntable 313 is rotatably installed on the inner wall of the installation cavity 1. A first rotating shaft 314 is fixedly connected to one side of the turntable 313. The first rotating shaft 314 penetrates through the installation cavity 1 and is fixedly connected to a first pulley 315; A spring rod 61 is fixedly installed on the top of the U-shaped mounting bracket 5. A fixed block 62 is fixedly connected to the top of the spring rod 61. A fourth pulley 63 is rotatably installed on one side of the fixed block 62. A third pulley 6 is rotatably installed on one side of the U-shaped mounting bracket 5. The first pulley 315, the third pulley 6 and the fourth pulley 63 are all driven by a second belt 64. The output shaft of the second motor 53 penetrates through the U-shaped mounting bracket 5 and is fixedly connected to 6 on one side.

[0036] When the present invention is in use, the soil blocks shoveled by the two buckets 258 move to the top of the leakage frame 32 and release the soil into the inner cavity of the leakage frame 32. When in use, the output shaft of the second motor 53 drives the third pulley 6 to rotate. Through the transmission of the second belt 64, the first pulley 315 also starts to rotate. Through the setting of the spring rod 61, the second belt 64 can be kept tight when the U-shaped mounting bracket 5 moves, and still can drive the first pulley 315, the third pulley 6 and the fourth pulley 63; When the first pulley 315 rotates, the first pulley 315 will drive the first rotating shaft 314 to rotate. The first rotating shaft 314 further drives the turntable 313 to rotate. The first connecting rod 312 is in an eccentric position of the turntable 313. When the first connecting rod 312 moves, the first connecting rod 312 will drive the two rotating rods 311 to do circular motion. The rotating rod 311 and the second sliding rod 31 generate relative rotation, and the second sliding rod 31 will drive the leakage frame 32 to move up and down. At this time, the soil blocks in the inner cavity of the leakage frame 32 will be broken, and the stones in the soil blocks will be left in the leakage frame 32, while the soil wrapping the stones will fall from the bottom of the leakage frame 32.

[0037] Working principle: First, push the entire soil-turning machine through the armrest 13. At this time, the roller frame 15 and the rotating wheel 45 are in contact with the ground and drive the soil-turning machine to move. When soil turning is required, the output end of the fifth electric telescopic rod 4 extends to drive the second rotating shaft 41 to slide on the inner surface of the arc-shaped groove 12. The second rotating shaft 41 drives the first connecting ear 421 to move. At the same time, the second connecting ear 422 rotates on the outer surface of the third rotating shaft 44. This can make the plow 42 move downward and the second connecting rod 43 rotate along the third rotating shaft 44 under the action of the second rotating shaft 41, thereby driving the rotating wheel 45 to move upward. At this time, pushing the soil-turning machine can achieve soil turning. When the soil-turning machine is moving, the first electric telescopic rod 23 drives the first mounting plate 21 to a horizontal state, so that the ultrasonic detector 22 can detect the stones in the soil. When stones are detected, the output end of the third electric telescopic rod 255 drives the second connecting block 256 and the fourth electric telescopic rod 26 to move downward. At the same time, the output shaft of the first motor 252 drives the threaded rod 253 to rotate, driving the first connecting block 254 to slide in the inner cavity of the first sliding rod 25, thereby moving the two buckets 258 above the stones. Then, the output end of the fourth electric telescopic rod 26 extends and drives the two limiting columns 262 to slide on the inner surface of the limiting groove 2571. This can make the two buckets 258 approach each other and shovel up a large lump of soil with stones. Then, under the combined action of the third electric telescopic rod 255 and the second electric telescopic rod 251, the bucket 258 is moved to the top of the leakage frame 32 and the lump of soil shoveled by the bucket 258 is released into the inner cavity of the leakage frame 32.

[0038] When turning the soil, the output shaft of the second motor 53 drives the second pulley 52 to rotate, and through the transmission of the first belt 54, the second pulley 52 at the bottom can drive the crushing roller 55 to rotate, thereby crushing the turned soil. The height of the crushing roller 55 can be adjusted by the sixth electric telescopic rod 51. When the second motor 53 is started, the output shaft of the second motor 53 will also drive the third pulley 6 to rotate. Through the transmission of the second belt 64, the first pulley 315 also starts to rotate. The first pulley 315 drives the turntable 313 to rotate through the first rotating shaft 314. The turntable 313 further drives the first connecting rod 312 to rotate. The first connecting rod 312 is connected to the rotating rod 311 and makes the rotating rod 311 drive the second sliding rod 31 to move up and down reciprocally. The second sliding rod 31 further drives the leakage frame 32 to move reciprocally. This can make the lump of soil wrapped with stones in the inner cavity of the leakage frame 32 scatter, and the soil will leak out from the bottom of the leakage frame 32, while the stones still remain in the inner cavity of the leakage frame 32. In order to enable the second belt 64 to always drive the third pulley 6 and the first pulley 315, the spring rod 61 supports the fixed block 62 and the fourth pulley 63, so that the second belt 64 can always remain taut and achieve transmission.
