Description

Technical Field

[0001] The present invention relates to the technical field of agricultural soil loosening, and in particular to a novel soil loosening mechanism for agricultural planting and a use method thereof. Background Art

[0002] A tiller is a device that uses mechanical force to break up and turn over the soil. It plays a vital role in agricultural planting. It can break up and turn over the soil, improve soil structure, increase soil permeability and water retention, and create good conditions for crop growth. The tiller uses the traction provided by the tractor and the weight of the tiller itself to make the tiller mechanism cut into the soil and loosen the hard soil. By adjusting the height of the frame, it can also achieve loosening operations at different depths. After the machine passes, a loose soil zone is left behind, which can break up the soil compaction. The improvement of soil structure is conducive to the breathing and growth of crop roots, thereby increasing crop yield and quality. Mechanized operations can greatly improve production efficiency and save manpower and material costs.

[0003] The loosening mechanism often encounters some hard soil during the loosening operation. The power system of the traditional loosening mechanism may not be able to match the cutting resistance of the hard soil, resulting in insufficient cutting depth of the loosening tool or interruption of the operation, and cannot effectively solve the problem of soil compaction. The sand and gravel or frozen soil in the hard soil will accelerate the wear of the loosening tool when it clumps. If a high-power loosening mechanism is used, although it can improve the quality of the loosening operation to a certain extent, it will increase the vibration of the loosening mechanism during the loosening operation. The existing loosening mechanism is mostly hand-held to facilitate the control of the loosening direction and depth. Long-term intense vibration may increase the load on the user, resulting in problems such as the loosening mechanism falling out of the hand, and there are certain safety hazards. For this reason, we propose a new loosening mechanism for agricultural planting and a method of using it. Summary of the Invention

[0006] Preferably, two scraping strips for scraping off attached mud are slidably installed on the inner wall of the fender, a slider is fixedly installed at one end of each scraping strip, an elastic strip is fixedly connected between each slider and the fender, a slide plate is fixedly installed on each slider, and telescopic rods driven by a rotating shaft to perform circular motion are provided at both ends of the fender, and each slide plate is located on the motion trajectory of the end of the telescopic rod.

[0007] Preferably, both ends of the mudguard are provided with arc-shaped grooves for limiting the slider, and both ends of the mudguard are fixedly installed with baffles for limiting the end of the telescopic rod, the baffles have the same curvature as the arc-shaped groove, each baffle is provided with a limiting groove, each of the slides is slidably installed in the limiting groove, and the diameter of the end of the telescopic rod is larger than the width of the limiting groove.

[0008] Preferably, a first gear is fixedly installed at both ends of the rotating shaft, each of the first gears is rotatably installed on the end of the fender, and a second gear meshing with the first gear is rotatably installed at both ends of the fender, the diameter of the second gear is larger than the diameter of the first gear, and each of the telescopic rods is fixedly installed on the corresponding second gear.

[0009] Preferably, each end of the sliding rod is fixedly mounted with a magnetic plate, each of the balls is rotatably mounted on the corresponding magnetic plate, and two magnetic blocks for generating magnetic attraction to the magnetic plate are symmetrically fixedly mounted on the rotating shaft, and the magnetic blocks are located at the initial end of the spiral groove.

[0010] Preferably, each of the sleeves is fixedly mounted with a plurality of crushing discs for crushing soil lumps, the crushing discs are evenly distributed between the fixed discs, and a plurality of fixed plates for dispersing soil are fixedly connected between two adjacent fixed discs, and each of the crushing discs is fixedly connected to the corresponding fixed plate.

[0012] Preferably, a guide bar is fixedly mounted on the inner wall of one end of each sleeve, and a guide groove matching the guide bar is provided on each slide rod.

[0013] Preferably, each of the torsion springs is provided with a rubber sleeve for blocking mud, and both ends of each of the rubber sleeves are fixedly connected to the corresponding rotating shaft and sleeve respectively.

[0014] A method for using a new soil loosening mechanism for agricultural planting, comprising the following steps: S1. Prepare for operation and check the mechanical parts, power mechanism and safety devices of the equipment; S2. Survey the site, clear obstacles, and remove hard objects such as stones and tree roots to avoid damaging the blade; S3. Conduct a trial run, complete the no-load test and load test, adjust the soil scarification depth, and plan the route; S4. The power mechanism is officially started, and the machine is driven to perform soil loosening operations along the predetermined route. The output shaft of the power mechanism drives the rotating shaft to rotate, and the rotating shaft drives the sleeve to rotate through the transmission of the torsion spring. The sleeve drives the loosening knife and the crushing disc to rotate. The loosening knife can scrape the soil during the rotation process. After the soil scraped by the loosening knife enters between the two adjacent fixed discs, the crushing disc can crush the soil for the second time. At the same time, the soil will be hit by the fixed plate during the falling process, which changes the falling trajectory of the soil and facilitates the soil to contact the loosening knife and the crushing disc again for crushing; S5. When the soil hardness exceeds a certain range, the resistance encountered by the loosening knife gradually increases, and eventually overcomes the magnetic attraction between the magnetic block and the magnetic plate and the elastic force of the torsion spring itself, causing the sleeve and the rotating shaft to rotate relative to each other. The slide rod will perform a circular motion while sliding toward the adjustment bin, and the ball will contact the liquid adding induction ring. The control valve will control the sprinkler to spray the loosening agent until the soil hardness returns to the appropriate range, and then the ball will no longer contact the liquid adding induction ring and will be located between the liquid adding induction ring and the liquid reducing induction ring. When the soil hardness changes again, if the soil is too hard, the ball will contact the liquid adding induction ring again, and the sprinkler spraying dosage will increase again. If the soil hardness becomes softer, the ball will contact the liquid reducing induction ring, causing the sprinkler spraying dosage to decrease until the soil hardness is at the appropriate hardness after spraying the loosening agent, and then the ball will be located between the liquid adding induction ring and the liquid reducing induction ring again. S6. After operation, remove the dirt and weeds on the loosening knife and crushing disc to prevent corrosion and perform maintenance on the machine.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention utilizes the output shaft to drive the rotating shaft to rotate, and the rotating shaft drives the sleeve to rotate through the transmission of the torsion spring. When the soil texture is relatively loose, the loosening knife is subject to less resistance, and the sleeve and the rotating shaft will not rotate relative to each other. The sleeve will drive the loosening knife and the crushing disk to rotate synchronously with the rotating shaft. After the soil scraped by the loosening knife enters between two adjacent fixed disks, the crushing disk can crush the soil for the second time, thereby improving the loosening effect and reducing the clumping of soil after loosening. At the same time, the soil will be slapped by the fixed plate during the falling process, which changes the falling trajectory of the soil and facilitates the soil to contact with the loosening knife and the crushing disk again for crushing.

[0016] The present invention utilizes a loosening knife to detect the hardness of the soil. When the soil gradually becomes hard, the resistance encountered by the loosening knife gradually increases, and eventually overcomes the magnetic attraction between the magnetic block and the magnetic plate and the elastic force of the torsion spring itself, causing the sleeve and the rotating shaft to rotate relative to each other. The slide rod will perform a circular motion while sliding toward the adjustment bin, and the ball will no longer contact the liquid-reducing induction ring. When the soil hardness exceeds a certain range, the ball will contact the liquid-adding induction ring. At this time, the control valve will control the sprinkler to spray the loosening agent until the soil hardness returns to an appropriate range. The ball will then be located between the liquid-adding induction ring and the liquid-reducing induction ring, and the control valve will control the sprinkler to spray according to the appropriate dosage. The dosage of the loosening agent sprayed can be adjusted in real time according to the soil hardness to prevent the soil from being too hard and failing to achieve a good loosening effect, and to avoid waste caused by excessive spraying of the loosening agent.

[0017] The present invention utilizes a rotating shaft to drive the first gear and the second gear on both sides to rotate, and drives the telescopic rod to perform circular motion. The end of the telescopic rod will contact the slide plate and drive the slide plate to move along the baffle. At the same time, the slider and the scraper will move along the inner wall of the mudguard and scrape off the soil adhered to the inner wall of the mudguard to prevent the soil from adhering to the inner wall of the mudguard after being moistened by the loosening agent. When the slide plate moves to the end of the limit groove, it is far away from the second gear. The telescopic rod is fully extended at this time and cannot contact the slide plate. The elasticity of the elastic strip will pull the slider and the slide plate to reset to the initial position, and the scraper will scrape the inner wall of the mudguard in the opposite direction.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-9The present invention provides a technical solution: a new type of soil loosening mechanism for agricultural planting, including a frame 1, a power mechanism 2 fixedly mounted on the frame 1, a transmission box 6 fixedly mounted on the lower end of the frame 1, an output shaft 8 of the power mechanism 2 rotatably mounted in the transmission box 6, a rotating shaft 10 rotatably mounted on the transmission box 6, a bevel gear 9 fixedly mounted on the lower end of the output shaft 8, a bevel gear plate 11 meshing with the bevel gear 9 fixedly mounted on the rotating shaft 10, two sleeves 12 rotatably mounted on the rotating shaft 10, each sleeve 12 is fixedly connected to the rotating shaft 10 at both ends with a torsion spring 13, and each torsion spring 13 is provided with a rubber sleeve for blocking soil. 16. Both ends of each rubber sleeve 16 are fixedly connected to the corresponding rotating shaft 10 and sleeve 12 respectively. A number of fixed discs 14 are fixedly installed on each sleeve 12. A number of loosening knives 15 are fixedly installed on each fixed disc 14. The loosening knives 15 on each fixed disc 14 are arranged in a ring shape. The end of each loosening knife 15 is arranged in an arc shape, and the bending directions of the ends of two adjacent loosening knives 15 are set in opposite directions. A number of crushing discs 17 for crushing soil lumps are fixedly installed on each sleeve 12. The crushing discs 17 are evenly distributed between the fixed discs 14. There are fixed connections between two adjacent fixed discs 14. Several fixed plates 18 are used to disperse the soil. Each crushing disk 17 is fixedly connected to the corresponding fixed plate 18. The edge of each loosening knife 15 and the edge of each crushing disk 17 are set to a wedge shape to facilitate crushing the soil. After the power mechanism 2 is started, it will drive the output shaft 8 to rotate, and through the transmission of the bevel gear 9 and the bevel gear disk 11, it will drive the rotating shaft 10 to rotate. The rotating shaft 10 drives the sleeve 12 to rotate through the transmission of the torsion spring 13. When the soil texture is relatively soft, the loosening knife 15 is subjected to less resistance, and the sleeve 12 and the rotating shaft 10 will not rotate relative to each other. The sleeve 12 will drive the loosening knife 15 and the crushing disk 17 and The rotating shaft 10 rotates synchronously, and the loosening knife 15 can scrape up the soil during the rotation process. Since the bending directions of the ends of the two adjacent loosening knives 15 are set in opposite directions, the loosening area of ​​the loosening knife 15 is increased, ensuring that the soil can be effectively loosened wherever the machine passes. After the soil scraped up by the loosening knife 15 enters between the two adjacent fixed disks 14, the crushing disk 17 can crush the soil for the second time, thereby improving the loosening effect and reducing the clumping of soil after loosening. At the same time, the soil will be beaten by the fixed plate 18 during the falling process, which changes the falling trajectory of the soil and facilitates the soil to contact and be crushed with the loosening knife 15 and the crushing disk 17 again.

[0022] A liquid storage tank 3 for storing a loosening agent is fixedly installed on the frame 1 (the loosening agent used in the present invention can be a fast-acting natural loosening agent, such as beer dilution, rice vinegar solution, etc., which can quickly take effect on the surface compacted soil after spraying), control valves 4 are fixedly installed on both sides of the liquid storage tank 3, and a plurality of nozzles 5 are fixedly installed on the lower end of each control valve 4. Adjustment bins 7 are provided on both sides of the transmission box 6, and a slide rod 26 is installed for transverse sliding at one end of each sleeve 12. A guide bar 24 is fixedly installed on the inner wall of one end of each sleeve 12, and a guide groove 25 that cooperates with the guide bar 24 is provided on each slide rod 26. The end of each slide rod 26 is located in the corresponding adjustment bin 7, and each slide rod 26 A limit block 29 is fixedly installed at one end, and two movable grooves 21 for limiting the slide rod 26 are symmetrically provided on the rotating shaft 10, and a spiral groove 22 for limiting the limit block 29 is provided on the inner wall of each movable groove 21. A ball 28 is provided at one end of each slide rod 26, and a magnetic plate 27 is fixedly installed at the end of each slide rod 26. Each ball 28 is rotatably installed on the corresponding magnetic plate 27. Two magnetic blocks 23 for generating magnetic attraction to the magnetic plate 27 are symmetrically fixed on the rotating shaft 10. The magnetic block 23 is located at the initial end of the spiral groove 22. A liquid addition induction ring 19 and a liquid reduction induction ring 20 for adjusting the control valve 4 are respectively fixedly installed on the inner walls on both sides of each regulating chamber 7. In the initial state, as shown in the attached Figure 4As shown, the magnetic block 23 generates a magnetic attraction on the magnetic plate 27, and the torsion spring 13 is not rotated by force, the limit block 29 will be located at the initial end of the spiral groove 22, and the ball 28 will contact the liquid reduction induction ring 20, so that the control valve 4 will not spray the loosening agent through the nozzle 5. When loosening relatively soft soil, the loosening knife 15 is subject to less resistance. The magnetic attraction between the magnetic block 23 and the magnetic plate 27 plus the elastic force of the torsion spring 13 itself will prevent the sleeve 12 and the rotating shaft 10 from rotating relative to each other, and the ball 28 will continue to contact the liquid reduction induction ring 20. When the soil gradually becomes hard, the resistance to the loosening knife 15 gradually increases, and eventually overcomes the magnetic attraction between the magnetic block 23 and the magnetic plate 27 and the elastic force of the torsion spring 13 itself, so that the sleeve 12 The sleeve 12 rotates relative to the rotating shaft 10, and the guide groove 25 limits the guide bar 24. The sleeve 12 always rotates synchronously with the slide bar 26. When the sleeve 12 and the rotating shaft 10 rotate relative to each other, the slide bar 26 will also slide in the movable groove 21. At the same time, the spiral groove 22 limits the limit block 29. The slide bar 26 will perform a circular motion while sliding toward the regulating chamber 7, and the ball 28 will no longer contact the liquid reduction induction ring 20. When the soil does not reach the hardness required to spray the loosening agent, the ball 28 will not contact the liquid addition induction ring 19. The end of the slide bar 26 can drive the ball 28 to slide horizontally repeatedly in the regulating chamber 7. When the soil hardness exceeds a certain range, the ball 28 will contact the liquid addition induction ring 19. At this time The control valve 4 will control the sprinkler head 5 to spray the loosening agent, and then the loosening knife 15 will loosen the soil sprayed with the loosening agent. If the soil initially sprayed with the loosening agent is still too hard, the ball 28 will continue to contact the liquid adding induction ring 19, and the control valve 4 will continue to increase the dosage of the loosening agent sprayed by the sprinkler head 5 until the soil hardness returns to an appropriate range, and then the ball 28 will no longer contact the liquid adding induction ring 19, and will be located between the liquid adding induction ring 19 and the liquid reducing induction ring 20. The control valve 4 will control the sprinkler head 5 to spray according to the appropriate dosage. When the soil hardness changes again, if the soil is too hard, the ball 28 will contact the liquid adding induction ring 19 again, and the spraying dosage of the sprinkler head 5 will increase again. If the soil hardness becomes soft, the ball 28 will contact the liquid reducing induction ring 2 0 contact, so that the spraying metering of the nozzle 5 is reduced until the soil hardness is at an appropriate hardness after spraying the loosening agent, and then the ball 28 will be located between the liquid addition induction ring 19 and the liquid reduction induction ring 20 again, and the spraying dosage of the loosening agent can be adjusted in real time according to the soil hardness to prevent the soil from being too hard and unable to achieve a good loosening effect, and to avoid excessive spraying of the loosening agent causing waste or excessive soil moisture causing adhesion. At the same time, adjustment bins 7 are provided on both sides of the transmission box 6 to detect the resistance of the loosening knives 15 on the two sleeves 12 respectively, so that when the loosening knives 15 on both sides of the machine are loosening different soils, the two control valves 4 can respectively control the spraying dosage of the nozzle 5, thereby improving the accuracy of the spraying dosage of the loosening agent.

[0023] A mudguard 30 for preventing soil splashing is fixedly installed on the transmission box 6. Two scraping strips 31 for scraping off attached soil are slidably installed on the inner wall of the mudguard 30. A slider 36 is fixedly installed at one end of each scraping strip 31. An elastic strip 37 is fixedly connected between each slider 36 and the mudguard 30. A slide plate 38 is fixedly installed on each slider 36. A telescopic rod 34 driven by the rotating shaft 10 for circular motion is provided at both ends of the mudguard 30. Each slide plate 38 is located on the motion trajectory of the end of the telescopic rod 34. A first gear 32 is fixedly installed at both ends of the rotating shaft 10. Each first gear 32 is rotatably installed on the end of the mudguard 30. A second gear 33 meshing with the first gear 32 is rotatably installed at both ends of the mudguard 30. The diameter of the second gear 33 is larger than the diameter of the first gear 32. Each telescopic rod 34 is provided with a plurality of springs 20, 21 and 22. 34 are fixedly mounted on the corresponding second gear 33, and arc grooves 40 are provided at both ends of the fender 30 for limiting the slider 36. Baffles 35 for limiting the end of the telescopic rod 34 are fixedly mounted on both ends of the fender 30, and the baffles 35 have the same curvature as the arc grooves 40. A limiting groove 39 is provided on each baffle 35, and each slide plate 38 is slidably mounted in the limiting groove 39. The diameter of the end of the telescopic rod 34 is larger than the width of the limiting groove 39. The rotating shaft 10 will drive the first gears 32 on both sides to rotate synchronously during the rotation process, and the second gear 33 will be driven to rotate through the engagement of the first gear 32 and the second gear 33. Since the diameter of the second gear 33 is larger than the diameter of the first gear 32, the second gear 33 will rotate slowly and drive the telescopic rod 34 to perform a circular motion. In the initial state, as shown in the attached Figure 7As shown, the slider 36 is pulled by the elastic strip 37 and will be located at the initial end of the arc groove 40. During the rotation of the telescopic rod 34, its end will contact the slide plate 38 and drive the slide plate 38 to move along the baffle 35. At the same time, the slider 36 and the scraper strip 31 will move along the inner wall of the mudguard 30 and scrape off the soil adhering to the inner wall of the mudguard 30 to prevent the soil from adhering to the inner wall of the mudguard 30 after being moistened by the loosening agent. During the movement of the slide plate 38 driven by the telescopic rod 34, the end of the telescopic rod 34 will move along the lower end of the baffle 35. Since the lower end of the baffle 35 is fan-shaped, and the center of movement of the telescopic rod 34 does not coincide with the center of the fan, the end of the telescopic rod 34 will be compressed or extended along with the inner wall of the lower end of the baffle 35, and the slide plate 38 is located at the initial end of the limit groove 39. When the sliding plate 38 is in the extended position, the sliding plate 38 is pushed by the telescopic rod 34 to move. When the sliding plate 38 reaches the end of the limiting groove 39, the slider 36 also moves to the end of the arc groove 40. At this time, the sliding plate 38 is far away from the second gear 33, and the telescopic rod 34 is in the longest position and cannot contact the sliding plate 38. The sliding plate 38 will no longer be limited. The elasticity of the elastic strip 37 will pull the slider 36 and the sliding plate 38 to their initial positions. At the same time, the scraping strip 31 will scrape the inner wall of the fender 30 in the opposite direction, and then the second gear 33 will drive the telescopic rod 34 to continue to perform circular motion until the end of the telescopic rod 34 contacts the sliding plate 38 again. The above motion is repeated to repeatedly scrape off the mud adhering to the inner wall of the fender 30.

[0024] Specifically, after the power mechanism 2 is started, it drives the output shaft 8 to rotate, and through the transmission of the bevel gear 9 and the bevel gear plate 11, it will drive the rotating shaft 10 to rotate. The rotating shaft 10 drives the sleeve 12 to rotate through the transmission of the torsion spring 13, and the sleeve 12 will drive the loosening knife 15 and the crushing disk 17 to rotate. The loosening knife 15 can scrape the soil during the rotation process. After the soil scraped by the loosening knife 15 enters between the two adjacent fixed disks 14, the crushing disk 17 can crush the soil for the second time. At the same time, the soil will be slapped by the fixed plate 18 during the falling process, which changes the falling trajectory of the soil and makes it easier for the soil to contact and crush with the loosening knife 15 and the crushing disk 17 again. When loosening relatively soft soil, the loosening knife 15 is subject to less resistance, and the magnetic block 2 The magnetic attraction between the magnetic block 23 and the magnetic plate 27 plus the elastic force of the torsion spring 13 itself will prevent the sleeve 12 and the rotating shaft 10 from rotating relative to each other, and the ball 28 will continue to contact the liquid-reducing induction ring 20. When the soil gradually becomes hard, the resistance to the loosening knife 15 gradually increases, and eventually overcomes the magnetic attraction between the magnetic block 23 and the magnetic plate 27 and the elastic force of the torsion spring 13 itself, causing the sleeve 12 and the rotating shaft 10 to rotate relative to each other, and the slide bar 26 will perform a circular motion while sliding toward the adjustment chamber 7, and the ball 28 will no longer contact the liquid-reducing induction ring 20. When the soil does not reach the hardness required to spray the loosening agent, the ball 28 will not contact the liquid-adding induction ring 19, and the end of the slide bar 26 can drive the ball 28 to slide horizontally repeatedly in the adjustment chamber 7. When the soil hardness exceeds When the soil hardness is within a certain range, the ball 28 will contact the liquid adding induction ring 19. At this time, the control valve 4 will control the sprinkler head 5 to spray the loosening agent, and then the loosening knife 15 will loosen the soil sprayed with the loosening agent. If the soil initially sprayed with the loosening agent is still too hard, the ball 28 will continue to contact the liquid adding induction ring 19, and the control valve 4 will continue to increase the dosage of the loosening agent sprayed by the sprinkler head 5 until the soil hardness returns to the appropriate range. Then the ball 28 will no longer contact the liquid adding induction ring 19 and will be located between the liquid adding induction ring 19 and the liquid reducing induction ring 20. The control valve 4 will control the sprinkler head 5 to spray according to the appropriate dosage. When the soil hardness changes again, if the soil is too hard, the ball 28 will contact the liquid adding induction ring 19 again, and the spraying dosage of the sprinkler head 5 will increase again. If the soil hardness When the soil becomes soft, the ball 28 will contact the liquid reduction induction ring 20, reducing the spraying amount of the sprinkler head 5 until the soil hardness is at an appropriate hardness after the loosening agent is sprayed, and then the ball 28 will be located between the liquid addition induction ring 19 and the liquid reduction induction ring 20 again. The rotating shaft 10 drives the first gears 32 on both sides to rotate synchronously during the rotation process. The engagement of the first gear 32 and the second gear 33 will drive the second gear 33 to rotate, and drive the telescopic rod 34 to perform a circular motion. The end of the telescopic rod 34 will contact the slide plate 38 and drive the slide plate 38 to move along the baffle 35. At the same time, the slider 36 and the scraper 31 will move along the inner wall of the mud guard 30 and scrape off the soil adhering to the inner wall of the mud guard 30. During the movement of the slide plate 38 driven by the telescopic rod 34,The end of the telescopic rod 34 will move along the lower end of the baffle 35. Since the lower end of the baffle 35 is fan-shaped, and the center of movement of the telescopic rod 34 does not coincide with the center of the fan, the end of the telescopic rod 34 will be compressed or extended along with the inner wall of the lower end of the baffle 35. When the slide 38 is located at the initial end of the limit groove 39, the telescopic rod 34 is at its longest state. During the movement of the telescopic rod 34 pushing the slide 38, it will first shorten and then extend again. When the slide 38 moves to the end of the limit groove 39, the slider 36 will also When the slide 38 reaches the end of the arc groove 40, the slide 38 is far away from the second gear 33. The telescopic rod 34, even at its longest position, cannot contact the slide 38 and will no longer limit the slide 38. The elasticity of the elastic strip 37 will pull the slider 36 and the slide 38 back to their initial positions. At the same time, the scraper strip 31 will scrape the inner wall of the fender 30 in the opposite direction. Then, the second gear 33 will drive the telescopic rod 34 to continue the circular motion until the end of the telescopic rod 34 contacts the slide 38 again, and the above motion will be repeated.

[0025] A method for using a new soil loosening mechanism for agricultural planting, comprising the following steps: S1. Perform pre-operation preparations and check the mechanical components, power mechanism 2, and safety devices of the equipment; S2. Survey the site, clear obstacles, and remove hard objects such as stones and tree roots to avoid damaging the blade; S3. Conduct a trial run, complete the no-load test and load test, adjust the soil scarification depth, and plan the route; S4, officially start the power mechanism 2, and push the machine to perform soil loosening operations along the predetermined route. The output shaft 8 of the power mechanism 2 will drive the rotating shaft 10 to rotate. The rotating shaft 10 drives the sleeve 12 to rotate through the transmission of the torsion spring 13. The sleeve 12 will drive the loosening knife 15 and the crushing disk 17 to rotate. The loosening knife 15 can scrape the soil during the rotation process. After the soil scraped by the loosening knife 15 enters between the two adjacent fixed disks 14, the crushing disk 17 can crush the soil for the second time. At the same time, the soil will be slapped by the fixed plate 18 during the falling process, which changes the falling trajectory of the soil, making it easier for the soil to contact the loosening knife 15 and the crushing disk 17 and be crushed again; S5. When the soil hardness exceeds a certain range, the resistance to the loosening knife 15 gradually increases, and eventually overcomes the magnetic attraction between the magnetic block 23 and the magnetic plate 27 and the elastic force of the torsion spring 13 itself, causing the sleeve 12 and the rotating shaft 10 to rotate relative to each other, and the slide rod 26 will perform a circular motion while sliding toward the regulating chamber 7, and the ball 28 will contact the liquid-adding induction ring 19, and the control valve 4 will control the nozzle 5 to spray the loosening agent until the soil hardness returns to the appropriate range, and then the ball 28 will no longer contact the liquid-adding induction ring. The ball 28 contacts the induction ring 19 and is located between the liquid adding induction ring 19 and the liquid reducing induction ring 20. When the soil hardness changes again, if the soil is too hard, the ball 28 contacts the liquid adding induction ring 19 again, and the spraying dosage of the sprinkler head 5 will increase again. If the soil hardness becomes softer, the ball 28 contacts the liquid reducing induction ring 20, causing the spraying dosage of the sprinkler head 5 to decrease until the soil hardness is at an appropriate hardness after spraying the loosening agent, and then the ball 28 will be located between the liquid adding induction ring 19 and the liquid reducing induction ring 20 again. S6. After the operation, remove the soil and weeds on the loosening knife 15 and the crushing disc 17 to prevent corrosion and perform maintenance on the machine.
