Technical Field

[0001] The present invention belongs to the technical field of soil conditioning, and particularly relates to a grassland soil microorganism conditioning device and method. Background Art

[0002] Soil microorganisms are an important part of the grassland ecosystem and play an important role in nutrient cycling, organic matter degradation, and maintenance of plant diversity. By utilizing the sensitivity of soil microorganisms to environmental changes and using their characteristic changes to characterize the current situation of the grassland ecosystem, early warning of degraded systems can be given. Therefore, technicians will condition grassland soil microorganisms.

[0003] In the prior art, when conditioning grassland soil microorganisms, it is necessary to sprinkle nutrient solution and loosen the grassland soil, which can make the grassland soil more fluffy, so that the microorganisms in the grassland soil can more fully absorb the nutrients in the nutrient solution. When the soil to be loosened is not surveyed and marked in advance, there will be stones in the soil. Therefore, when the soil loosening component loosens the soil, it is easily damaged by the collision of the stones, affecting the soil loosening effect and the efficiency of microorganisms in the grassland soil to absorb nutrients in the nutrient solution.

The electric telescopic plate is located at the bottom of the mounting block.

[0016] The present invention also provides a method for using the above-mentioned grassland soil microorganism conditioning device, including the following steps.

[0017] Step 1: Start the power structure so that the power shaft 4 drives the mounting ring and the soil-turning blades to rotate. Hold the handle and push the frame and the moving wheels to move, so that when the frame moves, the soil is loosened by the soil-turning blades. At the same time, the nutrient solution in the nutrient tank is sprayed into the loosened soil through the delivery pipe, so that the microorganisms in the grassland soil can more fully absorb the nutrients in the nutrient solution.

[0018] Step 2: When the frame and the moving wheels move, they drive the mounting plate and the baffle to move, so that the baffle drives the moving blades inserted into the soil at the bottom to move, initially loosening the soil. And the soil is sensed by the sensor. When a stone is sensed inside the soil, start the electric telescopic plate to move into the soil. Start the second motor to drive the rotating shaft to rotate, so that the second movable block drives the electric telescopic plate to move along the inner wall of the mounting block, so that the electric telescopic plate pushes the stone to move to one side of the connecting plate away from the soil-turning blade, which is convenient for preventing the stone from colliding with the soil-turning blade and affecting the soil-turning effect.

[0019] Step 3: When the stones in the soil are large and the electric telescopic plate cannot push the stones, and the stones are on the coaxial line of the soil-turning knife on the mounting plate or the soil-turning knife near the connecting rod, first start the first motor inside the slider to drive the rotating rod to rotate, so that the moving plate moves upward along the inner wall of the groove and the rotating rod, thereby driving the rotating plate to deflect, driving the first movable block to drive the connecting block to move along the inner wall of the bottom of the groove towards the rotating rod, so that the limiting rod separates from the limiting groove and moves inside the moving groove, thus no longer limiting the slider and the mounting ring. Then start the first electric push rod or the second electric push rod to drive the moving block to move, drive the middle mounting ring and the soil-turning knife to move towards the connecting rod or the mounting plate through the action of the fixing rod. When the moving block moves, it drives the movable rod inside one end of the second electric push rod or the first electric push rod to move, and stretches the connecting spring. The movement of the middle mounting ring drives the moving rod on one side to move outward from the fixed block, so that the moving rod on the other side moves into the fixed block, and makes the limiting block move along the outside of the power shaft, thereby driving the mounting ring on one side of the connecting plate or the mounting ring on one side of the connecting rod to drive the slider to move along the chute, and making the mounting ring move away from the connecting plate or the connecting rod along the power shaft. When the middle mounting ring moves towards the connecting rod or the connecting plate, the first elastic telescopic sleeve contracts, one of the second elastic telescopic sleeves stretches, and the other second elastic telescopic sleeve contracts to protect the moving rod and the fixed block between the mounting rings, so that the soil-turning knife near the connecting plate or the soil-turning knife on the mounting ring near the connecting rod avoids the stones;

[0020] Step 4: When the stone is on the coaxial line of the middle mounting ring, also start the first motor inside the slider on the inner wall of the mounting ring near the connecting plate side, and drive the rotating rod to rotate, so that the moving plate moves upward along the inner wall of the groove and the rotating rod, thereby driving the rotating plate to deflect, driving the first movable block to drive the connecting block to move towards the rotating rod, so that the limiting rod separates from the limiting groove and moves inside the moving groove, thus no longer limiting the slider and the mounting ring near the connecting plate side. Then start the first electric push rod to drive the moving block to move, so that the movable block on one side of the second electric push rod moves to stretch the connecting spring, and drive the middle mounting ring and the soil-turning knife to move towards the connecting rod through the action of the fixing rod. When the middle mounting ring moves to the side of the connecting rod and avoids the stone, the moving rod on its left side moves into the fixed block, driving the first elastic telescopic sleeve to contract, and the moving rod on its right side moves outward from the fixed block, driving the fixed block and the limiting block to move along the outer wall of the power shaft, so that the first spring telescopic sleeve stretches, and the second elastic telescopic sleeve between the mounting ring and the connecting plate stretches, so that after the middle mounting ring moves, it can still protect the moving rod and the fixed block. After the middle mounting ring avoids the stone, then move it back to the original position and continue to loosen the soil.

[0021] The beneficial effects of the present invention are:

[0022] (1) By adjusting the positions of the mounting ring and the soil-turning blade, the present invention can avoid hitting stones, prevent the soil-turning blade from being damaged, and affect the soil-turning effect of the soil-turning blade. Thus, the soil-loosening effect can be improved, and the efficiency of microorganisms in the grassland soil absorbing nutrients in the nutrient solution can be increased.

[0023] (2) The present invention initially loosens the soil through the baffle and the moving blade, senses the position of the stone through the sensor, and at the same time pushes the stone away from the soil-turning blade through the electric telescopic plate, avoiding the collision between the stone and the soil-turning blade, further improving the soil-loosening effect, and increasing the service life of the soil-turning blade.

Detailed implementation manner

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0037] The present invention provides a grassland soil microorganism conditioning device and method, as Figures 1 to 5 shown, which includes a frame 1. A connecting rod 2 is fixedly installed at the bottom of the frame 1. A soil-turning structure is arranged at the bottom of the connecting rod 2. A power structure 3 for driving the movement of the soil-turning structure is arranged at the top of the frame 1 and on one side of the connecting rod 2;

[0038] The soil-turning structure includes a power shaft 4, a connecting plate 5, a mounting ring 6, a soil-turning blade 7 and an adjusting structure 8. The power shaft 4 is rotatably connected to the bottom of the connecting rod 2. Connecting plates 5 are rotatably connected to both ends of the power shaft 4. A mounting ring 6 is arranged on the power shaft 4. The mounting ring 6 is slidably connected to the outer side of the power shaft 4. Soil-turning blades 7 are fixedly installed on the outer side of the mounting ring 6. The mounting ring 6 and the soil-turning blades 7 are linearly arranged on the power shaft 4. An adjusting structure 8 is arranged between the two mounting rings 6 inside the power shaft 4. Mounting plates 9 are arranged on both sides of the frame 1. Fixed rings 10 are rotatably connected to both ends of the power shaft 4 close to the connecting plates 5. The tops of the fixed rings 10 are fixedly installed with the bottoms of the mounting plates 9. Movable wheels are arranged on the front and rear sides of the frame 1. A handle is arranged on the top of the frame 1. A nutrient box 11 is arranged at the bottom of the handle. Nutrient solution is arranged inside the nutrient box 11. The nutrient box 11 is fixedly installed with the frame 1. Two delivery pipes 12 are fixedly installed at the bottom of the nutrient box 11.

[0039] Starting the power structure 3 causes the power shaft 4 to drive the mounting ring 6 and the soil-turning blade 7 to rotate. Hold the handle and push the frame 1 and the moving wheels to move, so that when the frame 1 moves, the soil is loosened by the soil-turning blade 7. At the same time, the nutrient solution inside the nutrient box 11 is sprayed into the loosened soil through the delivery pipe 12, so that the microorganisms in the grassland soil can absorb the nutrients in the nutrient solution more fully. When there are stones in the soil, the position of the mounting ring 6 and the soil-turning blade 7 is adjusted through the adjustment structure 8, so that the soil-turning blade 7 avoids the stones and prevents collisions with the stones, resulting in damage to the soil-turning blade 7 and affecting the soil-turning effect. When the stones are avoided, the mounting ring 6 and the soil-turning blade 7 are moved back to their original positions through the adjustment structure 8. As the frame 1 and the moving wheels move, the soil loosening continues, thereby improving the soil loosening effect and facilitating the full absorption of nutrients by the microorganisms in the grassland soil.

[0040] As Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 shown, the adjustment structure 8 includes a fixed block 81, a moving rod 82, a fixed rod 83, a first electric push rod 84, a moving block 85, a second electric push rod 86 and a movable rod 87. A fixed block 81 is arranged between the two mounting rings 6. Both sides inside the fixed block 81 are movably connected with a moving rod 82. One side of the moving rod 82 is fixedly installed on the side of the mounting ring 6 close to the fixed block 81. A fixed rod 83 is fixedly installed at the bottom of the middle mounting ring 6. A moving block 85 is fixedly installed at the bottom of the fixed rod 83. The first electric push rod 84 and the second electric push rod 86 are respectively installed on both sides of the moving block 85. The telescopic ends of the first electric push rod 84 and the second electric push rod 86 are movably connected with a movable rod 87. One side of the movable rod 87 is fixedly installed on the moving block 85.

[0041] The movable rod 82 and the fixed block 81 facilitate the connection of adjacent mounting rings 6 and soil-turning blades 7. At the same time, when the mounting ring 6 moves, the movable rod 82 moves into or out of the fixed block 81, thereby improving the stability of the movement of the mounting ring 6 and the soil-turning blade 7. The fixed rod 83 facilitates the connection of the middle mounting ring 6 and the movable block 85. Thus, when the first electric push rod 84 contracts to drive the movable block 85 to move, the movable rod 87 inside the telescopic end of the second electric push rod 86 moves towards the movable block 85, enabling the movable block 85 to drive the middle mounting ring 6 and the soil-turning blade 7 to move towards the connecting rod 2. As a result, the movable rod 82 on one side of the middle mounting ring 6 moves into the fixed block 81, and the other side moves out of the fixed block 81. When the movable rod 82 moves, it can drive the mounting ring 6 and the soil-turning blade 7 near the connecting plate 5 to move along the power shaft 4, away from the connecting plate 5. When the second electric push rod 86 contracts to drive the movable block 85 to move, the movable rod 87 inside the telescopic end of the first electric push rod 84 moves towards the movable block 85, enabling the movable block 85 to drive the middle mounting ring 6 and the soil-turning blade 7 to move towards the connecting plate 5. As a result, the movable rod 82 on one side of the middle mounting ring 6 moves into the fixed block 81, and the other side moves out of the fixed block 81. Thereby, when the movable rod 82 moves, it can drive the mounting ring 6 and the soil-turning blade 7 near the connecting rod 2 to move along the power shaft 4, away from the connecting rod 2. Therefore, the middle mounting ring 6 can move away from the connecting rod 2 or the connecting plate 5, enabling the mounting rings 6 on both sides of the middle mounting ring 6 to drive the soil-turning blades 7 to move respectively, avoiding stones and preventing the soil-turning blades 7 from being collided, which may affect the soil-turning effect.

[0042] As Figure 4 , Figure 5 , Figure 7 , Figure 8 shown, both the fixed block 81 and the movable rod 82 are located on the upper and lower sides of the power shaft 4. A limiting block is fixedly installed on one side of the fixed block 81 close to the power shaft 4, and the limiting block is slidably connected to the outer side of the power shaft 4. A first elastic telescopic sleeve 13 is fixedly installed between two mounting rings 6. Second elastic telescopic sleeves 14 are provided between the mounting ring 6 and the fixed ring 10, and between the connecting rod 2 and the mounting ring 6. The fixed block 81, the movable rod 82 and the limiting block are located inside the first elastic telescopic sleeve 13.

[0043] When the middle mounting ring 6 moves along the power shaft 4, the movable rod 82 drives the fixed block 81 and the limiting block to move along the outer wall of the power shaft 4, thereby improving the stability of the movement of the mounting ring 6. At the same time, the first elastic telescopic sleeve 13 and the second elastic telescopic sleeve 14 contract or stretch, which can protect the power shaft 4 between the mounting rings 6, preventing the movable rod 82, the fixed block 81 and the limiting block from adhering to soil during the soil-turning of the soil-turning blade 7, affecting the movement and thus affecting the position adjustment of the mounting ring 6 and the soil-turning blade 7.

[0044] As shown in Figure 5 , Figure 7 , Figure 8 , Figure 10 shown, a chute is provided at the top of the power shaft 4. At the bottom of the mounting rings 6 on both sides of the fixed rod 83, sliders 15 are fixedly installed. The sliders 15 are slidably connected to the chute. Installation grooves are provided inside both ends of the power shaft 4. The fixed end of the first electric push rod 84 is fixedly installed on the inner wall of the installation groove. The fixed end of the second electric push rod 86 is fixedly installed on one side of the mounting plate 9. The moving block 85 is slidably connected to the inner wall of the installation groove. A connecting spring is sleeved outside the movable rod 87. One end of the connecting spring is fixedly installed on one side of the moving block 85.

[0045] When the mounting rings 6 on both sides of the fixed rod 83 move, they drive the sliders 15 to move along the chute. The installation groove facilitates the installation of the first electric push rod 84, the moving block 85, and the second electric push rod 86. Through the action of the first electric push rod 84 and the second electric push rod 86, when the moving block 85 moves, it can make the middle mounting ring 6 move towards the direction of the first electric push rod 84 or the second electric push rod 86, so that the movable rod 87 moves along with the moving block 85, and the connecting spring is stretched, which is convenient for improving the stability of the movement of the moving block 85. Thus, the middle mounting ring 6 and the soil-turning blade 7 can drive the mounting rings 6 and the soil-turning blades 7 on both sides of the fixed rod 83 to move respectively, adjusting the positions of the mounting rings 6 and the soil-turning blades 7 on both sides of the fixed rod 83, and preventing the mounting rings 6 and the soil-turning blades 7 on both sides of the fixed rod 83 from being damaged when encountering stones.

[0046] As shown in Figure 5 , Figure 6 , Figure 9 shown, a limiting structure is provided inside the slider 15;

[0047] The limiting structure includes a first motor 16, a rotating rod 17, a moving plate 18, a rotating plate 19, a first movable block 20, a connecting block 21, and a limiting rod 22. A first motor 16 is provided inside the slider 15. The output end of the first motor 16 is drivingly connected to a rotating rod 17. One end of the rotating rod 17 is threadedly connected to a moving plate 18. Both ends of the bottom of the moving plate 18 are hinged to a rotating plate 19. The bottom of the rotating plate 19 is hinged to a first movable block 20. A connecting block 21 is fixedly installed on one side of the first movable block 20. A limiting rod 22 is fixedly installed on one side of the connecting block 21. Grooves are provided inside the slider 15. Limiting grooves are provided on both sides of the chute. The first motor 16 is fixedly installed on the inner wall of the top of the groove. The bottom of the rotating rod 17 is rotatably connected to the inner wall of the bottom of the groove. Both sides of the moving plate 18 are slidably connected to the inner walls of both sides of the groove. The first movable block 20 is slidably connected to the inner wall of the bottom of the groove. The connecting block 21 is located at the bottom of the moving block 85. The limiting rod 22 passes through one side of the slider 15 and is inserted into the limiting groove.

[0048] When it is necessary to move the mounting rings 6 and the soil-turning blades 7 on both sides of the fixed rod 83, first start the first motor 16 inside the slider 15 to drive the rotating rod 17 to rotate, so that the moving plate 18 moves upward along the inner wall of the groove and the rotating rod 17, thereby driving the rotating plate 19 to deflect, driving the first movable block 20 to drive the connecting block 21 to move along the inner wall of the bottom of the groove toward the direction of the rotating rod 17, so that the limiting rod 22 separates from the limiting groove and moves inside the moving groove, and no longer limits the sliders 15 and the mounting rings 6 on both sides of the fixed rod 83, facilitating the movement of the mounting rings 6 and the soil-turning blades 7 on both sides of the fixed rod 83. After the soil-turning blade 7 avoids the stones after adjustment, then move the mounting rings 6, the soil-turning blades 7 and the sliders 15 on both sides of the fixed rod 83 to their original positions, so that the limiting rod 22 is inserted into the limiting groove again, and then fix the sliders 15, the mounting rings 6 and the soil-turning blades 7 in place to improve stability and facilitate improving the soil-turning effect.

[0049] As Figure 1 , Figure 2 , Figure 11 shown, a baffle 23 is fixedly installed at the bottom of the front end of the mounting plate 9 and the vehicle frame 1. A moving blade 24 is fixedly installed at the bottom of the baffle 23. The baffle 23 is located between the moving wheels and the soil-turning blades 7. The moving blades 24 are linearly arranged at the bottom of the baffle 23. The baffle 23 and the moving blades 24 are symmetrically arranged with respect to the center of the vehicle frame 1. A sensor 25 is fixedly installed on one side of the moving blade 24. A mounting block 26 is fixedly installed at the rear of the baffle 23. A moving port is opened at the bottom of the mounting block 26. A second motor 27 is fixedly installed on the inner wall of the mounting block 26. The output end of the second motor 27 is fixedly installed with a rotating shaft 28. One side of the rotating shaft 28 is rotatably connected to the inner wall of the mounting block 26. One end of the rotating shaft 28 is threadedly connected to a second movable block 29. Both sides of the second movable block 29 are slidably connected to the inner wall of the mounting block 26. The bottom of the second movable block 29 passes through the moving port and is fixedly installed with an electric telescopic plate 30. The electric telescopic plate 30 is located at the bottom of the mounting block 26.

[0050] The baffle 23 facilitates preventing soil from splashing onto the moving wheels at the front side of the vehicle frame 1, thereby affecting the movement of the vehicle frame 1. The moving blade 24 is inserted into the soil. When the vehicle frame 1 and the moving wheels move, it drives the mounting plate 9 and the baffle 23 to move, so that the baffle 23 drives the moving blades inserted into the soil at the bottom to move, initially loosening the soil. And the sensor 25 senses the soil. When it senses that there are stones inside the soil, start the electric telescopic plate 30 to move into the soil, start the second motor 27 to drive the rotating shaft 28 to rotate, so that the second movable block 29 drives the electric telescopic plate 30 to move along the inner wall of the mounting block 26, so that the electric telescopic plate 30 pushes the stones to move to one side of the connecting plate 5 away from the soil-turning blade 7, facilitating preventing the stones from colliding with the soil-turning blade 7 and affecting the soil-turning effect.

[0051] The present invention also provides a method of using the above-mentioned grassland soil microorganism conditioning device, including the following steps:

[0052] Step 1: Start the power structure 3 so that the power shaft 4 drives the mounting ring 6 and the soil-turning knife 7 to rotate. Hold the handle and push the vehicle frame 1 and the moving wheels to move, so that when the vehicle frame 1 moves, the soil is loosened by the soil-turning knife 7, and at the same time, the nutrient solution in the nutrient tank 11 is sprayed into the loosened soil through the delivery pipe 12, so that the microorganisms in the grassland soil can more fully absorb the nutrients in the nutrient solution.

[0053] Step 2: When the vehicle frame 1 and the moving wheels move, they drive the mounting plate 9 and the baffle 23 to move, so that the baffle 23 drives the moving knife inserted into the soil at the bottom to move, initially loosening the soil, and the soil is sensed by the sensor 25. When a stone is sensed inside the soil, start the electric telescopic plate 30 to move into the soil, start the second motor 27 to drive the rotating shaft 28 to rotate, so that the second movable block 29 drives the electric telescopic plate 30 to move along the inner wall of the mounting block 26, so that the electric telescopic plate 30 pushes the stone to move to the side of the connecting plate 5 away from the soil-turning knife 7, which is convenient for preventing the stone from colliding with the soil-turning knife 7 and affecting the soil-turning effect.

[0054] Step 3: When the stones in the soil are large and the electric telescopic plate 30 cannot push the stones, and the stones are located on the coaxial line of the soil turning knife 7 of the mounting plate 9 or the soil turning knife 7 near the connecting rod 2, first start the first motor 16 inside the slider 15 to drive the rotating rod 17 to rotate, so that the moving plate 18 moves upward along the inner wall of the groove and the rotating rod 17, thereby driving the rotating plate 19 to deflect, driving the first movable block 20 to drive the connecting block 21 to move along the inner wall of the bottom of the groove towards the direction of the rotating rod 17, so that the limiting rod 22 separates from the limiting groove and moves inside the moving groove, thus no longer limiting the slider 15 and the mounting ring 6. Then start the first electric push rod 84 or the second electric push rod 86 to drive the moving block 85 to move, drive the mounting ring 6 in the middle and the soil turning knife 7 to move towards the direction of the connecting rod 2 or the mounting plate 9 through the action of the fixing rod 83. When the moving block 85 moves, it drives the movable rod 87 inside one end of the second electric push rod 86 or the first electric push rod 84 to move, and stretches the connecting spring. The movement of the mounting ring 6 in the middle drives one side of the moving rod 82 to move outward from the fixing block 81, makes the other moving rod 82 move inside the fixing block 81, and makes the limiting block move along the outside of the power shaft 4, thereby driving the mounting ring 6 on one side of the connecting plate 5 or the mounting ring 6 on one side of the connecting rod 2 to drive the slider 15 to move along the chute, and makes the mounting ring 6 move away from the connecting plate 5 or the connecting rod 2 along the power shaft 4. When the mounting ring 6 in the middle moves towards the connecting rod 2 or the connecting plate 5, the first elastic telescopic sleeve 13 contracts, one of the second elastic telescopic sleeves 14 stretches, and the other second elastic telescopic sleeve 14 contracts, protecting the moving rod 82 and the fixing block 81 between the mounting rings 6, so that the soil turning knife 7 near the connecting plate 5 or the soil turning knife 7 on the mounting ring 6 near the connecting rod 2 avoids the stones;

[0055] Step 4: When the stone is on the coaxial line of the middle mounting ring 6, also start the first motor 16 inside the slider 15 on the inner wall of the mounting ring 6 close to the connecting plate 5, and drive the rotating rod 17 to rotate, so that the moving plate 18 moves upward along the inner wall of the groove and the rotating rod 17, thereby driving the rotating plate 19 to deflect, driving the first movable block 20 to drive the connecting block 21 to move in the direction of the rotating rod 17, so that the limiting rod 22 separates from the limiting groove and moves inside the moving groove, thus no longer limiting the slider 15 and the mounting ring 6 close to the connecting plate 5. Then start the first electric push rod 84 to drive the moving block 85 to move, so that the movable block on one side of the second electric push rod 86 moves to drive the connecting spring to stretch, and drive the middle mounting ring 6 and the soil-turning knife 7 to move in the direction of the connecting rod 2 through the action of the fixed rod 83. When the middle mounting ring 6 moves to one side of the connecting rod 2 and avoids the stone, the moving rod 82 on its left side moves into the fixed block 81, driving the first elastic telescopic sleeve 13 to contract, and the moving rod 82 on its right side moves out of the fixed block 81, driving the fixed block 81 and the limiting block to move along the outer wall of the power shaft 4, so that the first spring telescopic sleeve stretches, and the second elastic telescopic sleeve 14 between the mounting ring 6 and the connecting plate 5 stretches. After the middle mounting ring 6 moves, it can still protect the moving rod 82 and the fixed block 81. After the middle mounting ring 6 avoids the stone, then move it back to the original position and continue to loosen the soil.

[0056] Working principle: Start the power structure 3 so that the power shaft 4 drives the mounting ring 6 and the soil-turning knife 7 to rotate. Hold the handle and push the vehicle frame 1 and the moving wheels to move, so that when the vehicle frame 1 moves, the soil is loosened by the soil-turning knife 7. At the same time, the nutrient solution in the nutrient box 11 is sprayed into the loosened soil through the delivery pipe 12, so that the microorganisms in the grassland soil can absorb the nutrients in the nutrient solution more fully. When the vehicle frame 1 and the moving wheels move, they drive the mounting plate 9 and the baffle 23 to move, so that the baffle 23 drives the moving knife inserted into the soil at the bottom to move, initially loosening the soil, and the soil is sensed by the sensor 25. When a stone is sensed inside the soil, start the electric telescopic plate 30 to move into the soil, start the second motor 27 to drive the rotating shaft 28 to rotate, so that the second movable block 29 drives the electric telescopic plate 30 to move along the inner wall of the mounting block 26, so that the electric telescopic plate 30 pushes the stone to move to one side of the connecting plate 5 away from the soil-turning knife 7, which is convenient for preventing the stone from colliding with the soil-turning knife 7 and affecting the soil-turning effect.

[0057] When the stones in the soil are relatively large and the electric telescopic plate 30 cannot push the stones, and the stones are located on the coaxial line of the soil-turning knife 7 of the mounting plate 9 or the soil-turning knife 7 near the connecting rod 2, first start the first motor 16 inside the slider 15 to drive the rotating rod 17 to rotate, so that the moving plate 18 moves upward along the inner wall of the groove and the rotating rod 17, thereby driving the rotating plate 19 to deflect, driving the first movable block 20 to drive the connecting block 21 to move along the inner wall of the bottom of the groove in the direction of the rotating rod 17, so that the limiting rod 22 separates from the limiting groove and moves inside the moving groove, thus no longer limiting the slider 15 and the mounting ring 6. Then start the first electric push rod 84 or the second electric push rod 86 to drive the moving block 85 to move, drive the mounting ring 6 and the soil-turning knife 7 in the middle to move in the direction close to the connecting rod 2 or the mounting plate 9 through the action of the fixing rod 83. When the moving block 85 moves, it drives the movable rod 87 inside one end of the second electric push rod 86 or the first electric push rod 84 to move, and stretches the connecting spring. The movement of the mounting ring 6 in the middle drives the moving rod 82 on one side to move outward from the fixing block 81, makes the other moving rod 82 move inside the fixing block 81, and makes the limiting block move along the outside of the power shaft 4, thereby driving the mounting ring 6 on one side of the connecting plate 5 or the mounting ring 6 on one side of the connecting rod 2 to drive the slider 15 to move along the chute, and making the mounting ring 6 move away from the connecting plate 5 or the connecting rod 2 along the power shaft 4. When the mounting ring 6 in the middle moves in the direction of the connecting rod 2 or the connecting plate 5, the first elastic telescopic sleeve 13 contracts, one of the second elastic telescopic sleeves 14 stretches, and the other second elastic telescopic sleeve 14 contracts, protecting the moving rod 82 and the fixing block 81 between the mounting rings 6, so that the soil-turning knife 7 near the connecting plate 5 or the soil-turning knife 7 on the mounting ring 6 near the connecting rod 2 avoids the stones.

[0058] When the stone is located on the coaxial line of the mounting ring 6 in the middle, the first motor 16 inside the slider 15 on the inner wall of the mounting ring 6 close to the connecting plate 5 is also started, and the rotating rod 17 is driven to rotate, so that the movable plate 18 moves upward along the inner wall of the groove and the rotating rod 17, thereby driving the rotating plate 19 to deflect, and the first movable block 20 drives the connecting block 21 to move in the direction of the rotating rod 17, so that the limiting rod 22 is separated from the limiting groove and moves inside the groove, so that the slider 15 and the mounting ring 6 close to the connecting plate 5 are no longer limited, and then the first electric push rod 84 is started to drive the moving block 85 to move, so that the movable block on the side of the second electric push rod 86 moves to drive the connecting spring to stretch, and through the fixed rod 83 The action drives the middle mounting ring 6 and the soil-turning knife 7 to move in the direction of the connecting rod 2. When the middle mounting ring 6 moves to one side of the connecting rod 2 and avoids the stones, the moving rod 82 on its left side moves toward the inside of the fixed block 81, which drives the first elastic telescopic sleeve 13 to contract, so that the moving rod 82 on its right side moves to the outside of the fixed block 81, and drives the fixed block 81 and the limiting block to move along the outer wall of the power shaft 4, thereby stretching the first spring telescopic sleeve and stretching the second elastic telescopic sleeve 14 between the mounting ring 6 and the connecting plate 5, so that after the middle mounting ring 6 moves, it can also protect the moving rod 82 and the fixed block 81. After the middle mounting ring 6 avoids the stones, it moves to its original position and continues to loosen the soil.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
