Description
Technical Field
[0001] This utility model relates to the field of soil loosening technology, and more specifically, to a soil loosening device for agricultural planting. Background Technology
[0002] In existing agricultural soil loosening devices, the design of the soil loosening frame has certain limitations, especially the poor linkage effect of the soil loosening frame mixing part, and the installation and disassembly process of the soil loosening frame is not convenient enough, which affects the efficiency of equipment use and the ease of maintenance. As an agricultural tillage tool, the soil loosening device is mainly used to loosen the soil, improve the soil aeration and water permeability, and help promote crop growth.
[0003] Soil loosening frames typically consist of multiple mixing blades, gears, or other similar components. These components work together to loosen the soil through rotation, flipping, and other methods. However, in existing technologies, the linkage effect of the various parts of the soil loosening frame is not ideal. This may be due to poor coordination between components or insufficient design, resulting in poor uniformity of soil mixing and even situations where some areas fail to be loosened sufficiently.
[0004] The installation and dismantling of soil loosening frames usually rely on traditional mechanical structures, such as bolts, fixing devices, or clips. While these designs can ensure the sturdiness and stability of the soil loosening frame in some cases, they also make the installation and dismantling process complicated. During installation, operators usually need to spend a long time connecting parts and tightening bolts, especially when it is necessary to frequently replace the soil loosening frame or adjust the loosening depth and angle. Inconvenient operation may lead to a decrease in work efficiency. Utility Model Content

The soil loosening transmission mechanism includes an output motor and a gear box, which are fixedly installed at the top and bottom ends of the frame. An output shaft is installed at the output end of the output motor. A main tooth and a driven tooth are rotatably installed inside the gear box, and the main tooth and the driven tooth are meshed together. The output shaft is connected to the main tooth. A driven shaft is installed on two sets of driven teeth, and a rotating plate is hidden on the driven shaft. The frame body clamping mechanism includes a clamping tube and a clamping rod. A clamping plate is installed at one end of the clamping rod. An inclined sliding block is slidably installed on the inner wall of the clamping tube.

Guide blocks are installed on both sides of the longitudinal sliding frame. A guide groove is opened on the embedding block, and the guide block and the guide groove plate are directionally slidably arranged.
[0007] The present invention is further configured such that the snap-fit auxiliary mechanism includes an operating frame and a rotating block. The operating frame is rotatably mounted on the outer wall of the snap-fit tube. The operating frame is threadedly connected to the longitudinal movement frame. Multiple sets of rotating blocks are mounted on the bottom end of the operating frame. Positioning spring rods are installed on the rotating blocks. An outer retaining ring is fixedly installed on the outer wall of the snap-fit tube. Positioning holes are opened on the outer retaining ring. Positioning spring rods are embedded into the positioning holes in stages, so that the operating frame rotates stably on the outer wall of the snap-fit tube.
[0008] The present invention is further configured such that a steering rod is rotatably mounted around the frame, and a bottom wheel is mounted on one end of the steering rod.
[0009] The present invention is further configured such that a steering wheel is installed at the other end of the steering rod, an operating handle is rotatably installed on one side of the top end of the frame, and a drive belt is installed between the operating handle and the steering wheel.
[0010] The present invention is further configured such that a mounting bracket is installed at the top end of the frame, and the output motor is mounted on the mounting bracket.
[0011] The present invention is further configured such that a soil loosening frame is installed on the rotating plate, and multiple sets of soil loosening frames are provided.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a soil loosening device for agricultural planting, which has the following beneficial effects: 1. This utility model is equipped with a soil loosening transmission mechanism. The output motor drives the main gear in the gearbox to rotate through the output shaft. The main gear meshes with the driven gear to achieve power distribution and drive two sets of driven gears to rotate synchronously, ensuring transmission balance and stability. The driven shaft transmits the rotation to the rotating plate, which drives multiple sets of soil loosening frames to rotate and insert into the soil for soil loosening operations. The gear transmission structure has high transmission efficiency and balanced power distribution. The synchronous operation of multiple sets of soil loosening frames significantly improves soil loosening efficiency and operation quality.
[0015] 2. This utility model is equipped with a frame locking mechanism. The locking rod passes through the rotating plate and extends into the locking tube to achieve quick docking without tools. The inclined sliding block slides and presses against the clamping plate, using the inclined plane principle to generate a self-locking clamping force. When the longitudinal frame is pressed down, the guide block pushes the embedded block in the guide groove to drive the inclined sliding block to slide further, generating a greater clamping force to firmly lock the loosening frame. When lifted, it is quickly unlocked and separated, realizing the rapid installation, reliable fixation and convenient disassembly of the loosening frame, ensuring stable and safe connection during rotation operation.
[0016] 3. This utility model is equipped with a snap-fit auxiliary mechanism. The rotating operating frame achieves labor-saving operation by pushing the longitudinal moving frame through the thread, reducing the operating force. The positioning spring rods on multiple sets of rotating blocks are embedded into the positioning holes of the outer fixed ring in stages, generating clear tactile feedback, enabling the operator to accurately judge the locking state. The positioning spring rods provide stable rotation and precise positioning, significantly improving the convenience of operation, positioning accuracy and locking reliability.

[0022] Please see Figures 1-5 An agricultural soil loosening device includes a frame 1, a soil loosening transmission mechanism, a frame clamping mechanism, and a clamping auxiliary mechanism. The soil loosening transmission mechanism includes an output motor 2 and a gearbox 3. The output motor 2 and gearbox 3 are fixedly installed at the top and bottom ends of the frame 1, respectively. An output shaft 4 is installed at the output end of the output motor 2. A main gear 5 and a driven gear 6 are rotatably mounted inside the gearbox 3, with the main gear 5 meshing with the driven gear 6. The output shaft 4 is connected to the main gear 5. Driven shafts 7 are installed on the two sets of driven gears 6. A rotating plate 8 is provided on the shaft 7. The frame locking mechanism includes a locking tube 9 and a locking rod 10. A clamping plate 11 is installed at one end of the locking rod 10. An inclined sliding block 12 is installed on the inner wall of the locking tube 9. An embedded sliding block 13 is installed on one end face of the inclined sliding block 12. A longitudinal sliding frame 14 is installed on the outer wall of the locking tube 9. Guide blocks 15 are installed on both sides of the longitudinal sliding frame 14. A guide groove 16 is opened on the embedded sliding block 13. The guide block 15 and the guide groove 16 are oriented and slidably matched.
[0023] In this embodiment, after the output motor 2 starts, the output shaft 4 drives the main gear 5 in the gearbox 3 to rotate. The main gear 5 drives two sets of driven gears 6 to rotate synchronously through meshing. The driven shaft 7 on the driven gear 6 rotates accordingly, driving the rotating plate 8 to rotate. Multiple sets of loosening frames 28 installed on the rotating plate 8 are inserted into the soil as the rotating plate 8 rotates, realizing the loosening and turning of the soil. The loosening frame 28 is connected to the rotating plate 8 through the snap-fit rod 10. The snap-fit rod 10 passes through the rotating plate 8 and extends into the snap-fit tube 9. After the clamping plate 11 enters the snap-fit tube 9, the inclined block 12 slides along the inclined surface and presses against the clamping plate 11 to generate an initial clamping force. When the longitudinal frame 14 is pressed down, the guide blocks 15 on both sides of the longitudinal frame 14 slide in the guide groove 16 of the embedded block 13, pushing the embedded block 13 and the inclined block 12 to slide further, generating a greater clamping force to firmly lock the snap-fit rod 10. When the longitudinal frame 14 is lifted up, the guide block 15 pushes the embedded block 13 in the opposite direction, and the inclined block 12 resets and releases the clamping force, quickly unlocking and separating.
[0024] The locking auxiliary mechanism includes an operating frame 17 and rotating blocks 18. The operating frame 17 is rotatably mounted on the outer wall of the locking tube 9. The operating frame 17 is threadedly connected to the longitudinal frame 14. Multiple sets of rotating blocks 18 are mounted on the bottom end of the operating frame 17. Positioning spring rods 19 are installed on the rotating blocks 18. An outer retaining ring 20 is fixedly installed on the outer wall of the locking tube 9. Positioning holes 21 are opened on the outer retaining ring 20. The positioning spring rods 19 are inserted into the positioning holes 21 step by step, so that the operating frame 17 rotates stably on the outer wall of the locking tube 9.
[0025] In this embodiment, when the operating frame 17 is rotated, multiple sets of rotating blocks 18 at the bottom of the operating frame 17 rotate accordingly. The positioning spring rods 19 on the rotating blocks 18 are inserted into the positioning holes 21 of the outer retaining ring 20 step by step, generating clear positioning tactile feedback. The operating frame 17 is pushed down by the longitudinal moving frame 14 through the thread, realizing labor-saving operation and precise control of the locking depth. When rotating in the opposite direction, the positioning spring rods 19 assist in stable reset.
[0026] Please see Figures 1-5 As a further embodiment of the overall equipment: a steering rod 22 is rotatably mounted around the frame 1, a bottom wheel 23 is mounted on one end of the steering rod 22, and a steering wheel 24 is mounted on the other end of the steering rod 22. An operating handle 25 is rotatably mounted on one side of the top end of the frame 1. A drive belt 26 is installed between the operating handle 25 and the steering wheel 24. A mounting frame 27 is mounted on the top end of the frame 1, and the output motor 2 is mounted on the mounting frame 27. A soil loosening frame 28 is mounted on the rotating plate 8, and multiple sets of soil loosening frames 28 are provided. A connecting plate 29 is installed on the side wall of the clamping pipe 9. An installation groove 30 is opened on the rotating plate 8, and the connecting plate 29 is fixedly installed in the installation groove 30. One end of the soil loosening frame 28 is connected to the clamping rod 10, and the other end of the clamping rod 10 extends directionally through the rotating plate 8 and directionally extends into the clamping pipe 9 to engage.
[0027] More specifically, the operator controls the steering by operating handle 25. The drive belt 26 between handle 25 and steering wheel 24 transmits steering force. Steering wheel 24 drives steering rod 22 to rotate, and bottom wheel 23 changes direction to move the device. During operation, output motor 2 drives main gear 5 to rotate, which drives rotating plate 8 to rotate through driven gear 6. Multiple loosening frames 28 rotate with rotating plate 8 and are inserted into the soil to loosen the soil. When installing loosening frame 28, locking rod 10 and locking pipe 9 quickly connect, rotating operating frame 17 locks, and positioning spring rod 19 provides tactile feedback to ensure that the locking is in place. When replacing, rotating operating frame 17 in the opposite direction quickly unlocks and separates the loosening frame 28. The entire device realizes the rapid and reliable installation of loosening frame 28, labor-saving and convenient disassembly and replacement operation, and efficient soil loosening operation.
[0028] In summary, when the overall equipment is in use or running: when the soil loosening transmission mechanism needs to run, after the output motor 2 starts, the output shaft 4 drives the main gear 5 in the gearbox 3 to rotate. The main gear 5 drives the two sets of driven gears 6 to rotate synchronously through meshing. The driven shaft 7 on the driven gear 6 rotates accordingly, driving the rotating plate 8 to rotate. The multiple sets of soil loosening frames 28 installed on the rotating plate 8 are inserted into the soil as the rotating plate 8 rotates, realizing the soil loosening and turning operation.
[0029] When the frame clamping mechanism is in operation, the loosening frame 28 is connected to the rotating plate 8 through the clamping rod 10. The clamping rod 10 passes through the rotating plate 8 and extends into the clamping pipe 9. After the clamping plate 11 enters the clamping pipe 9, the inclined block 12 slides along the inclined surface and presses against the clamping plate 11 to generate an initial clamping force. When the longitudinal frame 14 is pressed down, the guide blocks 15 on both sides of the longitudinal frame 14 slide in the guide groove 16 of the embedded block 13, pushing the embedded block 13 and the inclined block 12 to slide further, generating a greater clamping force to firmly lock the clamping rod 10. When the longitudinal frame 14 is lifted up, the guide block 15 pushes the embedded block 13 in the opposite direction, and the inclined block 12 resets to release the clamping force, quickly unlocking and separating.
[0030] When the auxiliary mechanism needs to be engaged, when the operating frame 17 is rotated, the multiple sets of rotating blocks 18 at the bottom of the operating frame 17 rotate accordingly. The positioning spring rods 19 on the rotating blocks 18 are inserted into the positioning holes 21 of the outer retaining ring 20 step by step, generating clear positioning tactile feedback. The operating frame 17 is pushed down by the longitudinal moving frame 14 through the thread, realizing labor-saving operation and precise control of the locking depth. When rotating in the opposite direction, the positioning spring rods 19 assist in stable reset.
[0031] The operator controls the steering by operating handle 25. The drive belt 26 between handle 25 and steering wheel 24 transmits steering force. Steering wheel 24 drives steering rod 22 to rotate, and bottom wheel 23 changes direction to move the device. During operation, output motor 2 drives main gear 5 to rotate, which drives rotating plate 8 to rotate through driven gear 6. Multiple loosening frames 28 are inserted into the soil to loosen the soil as rotating plate 8 rotates. When installing loosening frame 28, locking rod 10 and locking pipe 9 are quickly connected, rotating operating frame 17 is locked, and positioning spring rod 19 provides tactile feedback to ensure that the locking is in place. When replacing, rotating operating frame 17 in the opposite direction can quickly unlock and separate the loosening frame 28. The entire device realizes the rapid and reliable installation of loosening frame 28, labor-saving and convenient disassembly and replacement operation, and efficient soil loosening operation.

For all the fixed connections mentioned above, welding is preferred.
