[0020] like Figure 1-5 As shown, this utility model provides a high-speed stubble harrow with a folding frame, including a support frame 1 for supporting various components. A fixed frame 11 is fixedly mounted at the top of the support frame 1. Symmetrically distributed rotating rods 12 are rotatably mounted inside the fixed frame 11. The rotation of the rotating rods 12 drives the rotation of a flipping frame 13. Symmetrically distributed flipping frames 13 are fixedly mounted on the outer side of the rotating rods 12. The rotation of the flipping frames 13 drives the rotation of a mounting plate 14. A mounting plate 14 is fixedly mounted at the bottom of the flipping frames 13. An array of harrow frames 2 are mounted on the outer side of the mounting plate 14. The harrow frames 2 are used for mounting and positioning harrow teeth 21. Harrow teeth 21 are mounted on the outer side of the harrow frames 2. Gears 15 are fixedly mounted on the outer side of the two rotating rods 12. The two gears 15 are connected... The two gears 15 mesh with each other, allowing the two rotating rods 12 to rotate in opposite directions. An adjusting frame 22 is fixedly provided on the outside of the support frame 1. A sliding groove 23 is provided inside the adjusting frame 22. The adjusting frame 22 and the sliding groove 23 are used to limit the wheel frame 24. The wheel frame 24 is slidably provided in the sliding groove 23. A tire 25 is rotatably provided in the wheel frame 24. A rotating plate 26 is fixedly provided on the outside of one of the rotating rods 12. A fixing rod 27 is fixedly provided on the outside of the rotating plate 26. An adjusting groove 28 is provided on the outside of the wheel frame 24. The fixing rod 27 is movably inserted into the adjusting groove 28. When the flipping frame 13 rotates, it drives the wheel frame 24 and the tire 25 to flip, thereby making the tire 25 contact the ground and improving the stability of the device.
[0021] A sliding frame 3 is movably fitted on the outer side of the mounting plate 14. A top plate 31 is rotatably mounted on the top of the sliding frame 3. Bolts 32 are fixedly arranged in a symmetrical manner on the top of the sliding frame 3. A square groove 34 is movably opened in the mounting plate 14 in a symmetrical manner. Bolts 32 are movably inserted through the square groove 34 and the top plate 31. A hexagonal nut 33 is threaded on the outer side of the bolt 32.
[0022] By adopting the above technical solution, the position of the rake teeth 21 can be adjusted, thereby adjusting the spacing between the rake teeth 21, and at the same time, it is convenient to disassemble and install them individually.
[0023] An auxiliary rod 29 is fixedly provided on the inner wall of the sliding groove 23, and the auxiliary rod 29 is movably inserted into the wheel frame 24.
[0024] By adopting the above technical solution, the auxiliary rod 29 can assist the wheel frame 24 in moving up and down, thereby improving the stability of the movement.
[0025] The rake frame 2 is detachably mounted on the bottom of the sliding frame 3 by screws.
[0026] By adopting the above technical solution, the rake frame 2 can be installed and disassembled at the bottom of the sliding frame 3.
[0027] The rake teeth 21 are detachably mounted on the outside of the rake frame 2 by screws.
[0028] By adopting the above technical solution, the rake teeth 21 can be installed and removed on the rake frame 2.
[0029] The top plate 31 is detachably mounted on the top of the sliding frame 3 by screws.
[0030] By adopting the above technical solution, the top plate 31 can rotate on the sliding frame 3, and is simultaneously positioned and installed on its top surface by screws.
[0031] A motor 18 is fixedly mounted on the outside of the fixed frame 11. The end of the output shaft of the motor 18 is inserted through the fixed frame 11 and fixedly connected to one of the rotating rods 12.
[0032] By adopting the above technical solution, the end of the output shaft of the motor 18 rotates, driving the rotating rod 12 to rotate, thereby providing power output.
[0033] A connecting plate 16 is fixedly provided on the outside of the support frame 1, and symmetrically distributed connecting holes 17 are provided in the connecting plate 16.
[0034] By adopting the above technical solution, the connecting plate 16 and the connecting hole 17 can connect and install the device with agricultural machinery.
[0035] Working principle: When in use, connect the connecting plate 16 to the agricultural machinery, and the harrow teeth 21 can be used to prune stubble. When not in use, start the motor 18, which rotates the output shaft of the motor 18, causing one of the rotating rods 12 to rotate. Simultaneously, under the action of the two gears 15, the two rotating rods 12 rotate in opposite directions, thereby causing the two tilting frames 13 to tilt, allowing the harrow teeth 21 and other components to be folded and stored. At the same time, the rotation of the rotating rod 12 causes the rotating plate 26 to rotate, which in turn causes the fixed rod 27 to swing. The swing of the fixed rod 27 causes the wheel frame 24 to move downward with the assistance of the sliding groove 23, thereby causing the tire 25 to contact the ground for support. When not in use, it can be tilted and stored. The folding mechanism, supported by the lowering of the tires 25, helps save storage space and reduce the area occupied by the equipment when not in operation. It also prevents damage or deformation of the rake teeth 21, extending the equipment's lifespan. The spacing between the rake teeth 21 can be adjusted as needed. Loosening the hexagonal nut 33 allows the sliding frame 3 to move on the mounting plate 14, while the bolt 32 slides within the square groove 34. Once the sliding frame 3 is in the desired position, tightening the hexagonal nut 33 limits its movement, allowing for adjustment of the rake tooth spacing. Removing the screws and hexagonal nut 33 above the top plate 31 allows for disassembly of the sliding frame 3 and rake teeth 21, facilitating subsequent maintenance and replacement.
[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
