[0002] The macadamia nut planting soil loosening device is an agricultural machinery designed to address soil hardening and compaction issues during macadamia nut cultivation. With the development of agricultural modernization and continuous technological innovation, the application prospects of the macadamia nut planting soil loosening device in agricultural production are becoming increasingly broad. It is not only suitable for soil loosening operations during macadamia nut cultivation, but can also be widely applied to soil improvement and irrigation operations during the cultivation of other fruit trees and crops.

[0003] Existing macadamia nut planting soil loosening devices typically use bolts and shackles to tighten and fix the hoe to the bottom of the vehicle body. The hoe can be replaced or repaired by tightening the bolts. Some macadamia nut planting soil loosening devices use rotating hoes to loosen the soil. The vehicle body moves forward, and the motor drives the hoe to rotate and contact the soil to achieve the soil loosening effect.

[0004] On the one hand, the existing method of fixing hoes with bolts is cumbersome to operate, requiring manual repeated tightening of bolts to disassemble and install the hoes, and manual lifting is also required, which is not convenient for large-scale soil loosening operations. On the other hand, existing hoes for soil loosening often use a fixed height, requiring the machine to be stopped and the hoes to be disassembled and installed manually by repeatedly tightening bolts to change to the required height. It is not possible to quickly adjust the soil loosening height of the hoes manually. Therefore, a soil loosening device for macadamia nut planting is proposed to solve the above problems.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a macadamia nut planting and soil loosening device, including a frame 1. An auxiliary groove 2 is provided on the inner outer wall of the frame 1. The auxiliary groove 2 is T-shaped and is used to engage an auxiliary plate 3 to maintain its stable rise and fall. An auxiliary plate 3 is slidably connected to the inner wall of the auxiliary groove 2. There are two sets of auxiliary plates 3. The auxiliary plates 3 are T-shaped and are used to engage the auxiliary groove 2 to move up and down, avoiding deformation and deviation caused by force. The two sets of auxiliary plates 3 are fixedly connected by a connecting rod 4. A motor 5 is fixedly connected to the bottom of the outer wall of the left auxiliary plate 3. The motor 5 is prior art and will not be described in detail. It is used to drive a transmission shaft 6 to drive a hoe 7 to contact the soil for soil loosening. The output shaft of the motor 5 is connected to the transmission shaft 6 through a quick-release assembly. The hoe 7 is fixedly connected to the outer wall of the transmission shaft 6. The top of the outer wall of the connecting rod 4 is in contact with the lower inner surface of the outer wall of the frame 1. The outer wall of the output shaft of the motor 5 passes through and is slidably connected to the bottom inner wall of the auxiliary plate 3. The end of the outer wall of the transmission shaft 6 is engaged with the inner wall of the right auxiliary plate 3 through a quick-release assembly.

[0034] Reference Figures 3-5A rack 8 is fixedly connected to the inner outer wall of a set of auxiliary plates 3 on the left side. The rack 8 is set to the same length as the auxiliary plate 3 and is used to drive the auxiliary plate 3 to rise or fall through the rotation of the gear 9. The rack 8 meshes with the gear 9. A rotating shaft 10 is fixedly connected to the center of the inner wall of the gear 9. The rotating shaft 10 is used to connect the gear 9 and the limiting component to play a transmission role. A directional block 11 is fixedly connected to the outer wall of the rotating shaft 10. The directional block 11 is used to engage with the directional groove 14 so that the rotating shaft 10 can rotate along with the limiting frame 13. The limiting frame 13 can also slide laterally on the outer wall of the rotating shaft 10. A limiting component is provided on the outer wall of the rotating shaft 10. The outer wall of the rack 8 is slidably connected to the inner wall of the frame 1. The outer wall of the gear 9 is slidably connected to the inner wall of the frame 1. The outer wall of the rotating shaft 10 is rotatably connected to the inner wall of the frame 1. The outer wall of the directional block 11 is slidably connected to the inner wall of the directional groove 14.

[0035] Reference Figures 3-5 The limiting component includes a limiting frame 13. A rocker arm is provided at the end of the outer wall of the limiting frame 13 for easy manual rotation. The inner wall of the limiting frame 13 is elastically connected to the end of the outer wall of the rotating shaft 10 via a limiting spring 12. A directional groove 14 is provided on the inner wall of the limiting frame 13. A limiting block 15 is fixedly connected to the end of the outer wall of the limiting frame 13. Two sets of limiting blocks 15 are provided, located at the upper and lower ends of the outer wall of the limiting frame 13, respectively, to engage with the limiting groove 16 to fix the rotation distance of the gear 9. A limiting groove 16 is provided on the left outer wall of the frame 1. The limiting groove 16 is provided with... Several sets are used to change the soil loosening height of the hoe blade 7 by engaging the limiting blocks 15. One end of the limiting spring 12 is fixedly connected to the outer wall end of the rotating shaft 10, and the other end of the limiting spring 12 is fixedly connected to the top of the inner wall of the limiting frame 13. Through the opposing extrusion force between the limiting spring 12 and the rotating shaft 10, the limiting block 15 is always locked on the inner wall of the limiting groove 16 without being affected by external force. The inner wall of the limiting frame 13 is slidably connected to the outer wall of the rotating shaft 10, and the outer wall end of the limiting block 15 is locked on the inner wall of the limiting groove 16.

[0036] Reference Figures 4-6The quick-release assembly includes a locking block 19, which is elastically connected to the inner wall of the drive shaft 6 via a return spring 22. A directional slider 20 is fixedly connected to the lower surface of the outer wall of the locking block 19. The directional slider 20 is used to keep the drive shaft 6 rotating with the quick-release frame 17 while the locking block 19 can move laterally via the quick-release switch 21, providing a counter-locking function. A quick-release switch 21 is fixedly connected to the upper surface of the outer wall of the locking block 19. The quick-release switch 21 is used for manual external release of the limit, eliminating the need for external tools. The outer wall of the locking block 19 is engaged with the quick-release frame 17. Here, the inner wall of the quick-release frame 17 engages the locking block 19 instead of a slot, providing a certain safe engagement distance for the locking block 19 and preventing the hoe blade 7 from falling off due to the rotation. The inner wall of the quick-release frame 17 has two sets of directional grooves, one of which is located on the drive shaft 6. On the inner wall, the locking block 19 is provided with a directional movement distance to avoid the return spring 22 being deformed and twisted by force. The two sets of directional slide grooves 18 engage the locking block 19 to form an opposing engagement shape. The outer wall of the locking block 19 is slidably connected to the inner wall of the drive shaft 6. One end of the return spring 22 is fixedly connected to the top of the inner wall of the drive shaft 6, and the other end of the return spring 22 is fixedly connected to the end of the outer wall of the locking block 19. Through the opposing pressing force between the return spring 22 and the drive shaft 6, the locking block 19 is always locked on the inner wall of the quick release frame 17 without being affected by external force. The outer wall of the directional slider 20 is slidably connected to the inner wall of the directional slide groove 18. The outer wall of the quick release switch 21 is through and slidably connected to the inner wall of the drive shaft 6. The end of the outer wall of the quick release frame 17 is fixedly connected to the output shaft of the motor 5, and the end of the outer wall of the quick release frame 17 is slidably connected to the outer wall of the auxiliary plate 3.

[0037] Working principle: When it is necessary to replace the hoe blade 7, the hoe blade 7 is lowered to the ground by the limiting component. Then, the quick-release switch 21 is manually turned on to drive the locking block 19 to disengage from the quick-release frame 17 and release the limiting. Then, the hoe blade 7 is manually pushed away from the bottom of the frame 1, and the new hoe blade 7 is pushed to the bottom of the frame 1. Then, the quick-release switch 21 is turned on again to drive the locking block 19 to retract to the inner wall of the drive shaft 6. Then, the drive shaft 6 is connected to the quick-release frame 17. After releasing the quick-release switch 21, the locking block 19 is returned to the quick-release frame 17 by the return spring 22 to complete the replacement. This achieves quick replacement of the hoe blade 7, eliminating the need to repeatedly tighten the bolts and manually lift the hoe blade 7, thus improving the efficiency of soil loosening operations.

[0038] When it is necessary to adjust the soil loosening height, the limit frame 13 is manually pulled to disengage the limit block 15 from the limit groove 16 to release the limit. Then, the limit frame 13 is rotated to drive the rotating shaft 10 to rotate, which in turn drives the gear 9 to rotate. The gear 9 drives the rack 8 to rise or fall, which in turn drives the auxiliary plate 3 to rise or fall. The auxiliary plate 3 then drives the transmission shaft 6 to rise or fall, which in turn drives the hoe 7 to rise or fall to the required height. Finally, the limit frame 13 is pushed to engage the limit block 15 into the corresponding limit groove 16 for locking and fixing. Then, the motor 5 is turned on to rotate the hoe 7. The frame 1 is then manually pushed or moved by an external traction device to loosen the soil, thus achieving rapid adjustment of the soil loosening height, increasing the range of application of the device, and improving the soil loosening efficiency.
