Description

Technical Field

[0001] This utility model relates to the technical field of blades for micro-tillers, specifically a blade for micro-tillers. Background Technology

[0002] Mini tillers are powered by small diesel or gasoline engines and are characterized by their light weight, small size, and simple structure. They are widely applicable to dry land, paddy fields, and orchards in plains, mountains, and hills. When equipped with appropriate implements, they can perform operations such as pumping water, generating electricity, spraying pesticides, and watering. They can also tow trailers for short-distance transportation. Mini tillers can move freely in the fields, making them convenient for users to use and store. They eliminate the problem of large agricultural machinery being unable to enter mountainous fields, making them the best alternative to oxen for farmers.

[0003] However, existing mini-tillers typically connect the blades to the shaft via threads. This connection method requires threaded holes to be drilled in the blades. During operation, the threads in the threaded holes are prone to wear. Since the threaded holes are on the blades, the blades are also prone to failure due to wear of the threaded holes. Furthermore, installation via bolts can easily cause wear on the surface of the blades. Therefore, a new type of blade for mini-tillers is proposed to address the above problems. Utility Model Content

[0028] The mounting assembly includes a positioning rod 7, a mounting plate 8, a mounting block 9, a positioning hole 10, a connecting hole 11, and a locking screw 12. The positioning rod 7 is mounted on the inner wall of the fixing plate 21, the mounting plate 8 is mounted on the outer surface of the positioning rod 7, the mounting block 9 is mounted on the inner wall of the mounting plate 8, the positioning hole 10 is provided above the mounting block 9, the connecting hole 11 is provided on the right side of the mounting hole 6, and the locking screw 12 is installed inside the fixing plate 21.

[0029] Furthermore, the tool holder 5 forms a locking structure with the mounting base 2 through the mounting groove 3, mounting rod 4, and mounting hole 6, thereby locking the tool holder 5 with the mounting base 2 through the mounting groove 3, mounting rod 4, and mounting hole 6.

[0030] Furthermore, the mounting block 9 is engaged with the mounting groove 3. Four sets of mounting blocks 9 are provided. The mounting blocks 9 engage and compress the mounting groove 3 to ensure the stability of the connection between the tool holder 5 and the tool holder 5.

[0031] Furthermore, the mounting plate 8 forms a locking structure with the mounting base 2 through the positioning hole 10 and the positioning rod 7. The fixing plate 21 forms a detachable structure with the mounting plate 8 through the locking screw 12. The tool holder 5 is locked to the positioning rod 7 through the connecting hole 11. The mounting plate 8 is locked to the mounting base 2 through the positioning hole 10 and the positioning rod 7. The mounting block 9 locks and presses against the mounting groove 3. The tool holder 5 is connected to the positioning rod 7 through the connecting hole 11, thus locking the tool holder 5 inside the mounting groove 3. The locking screw 12 is then rotated to install and remove the tool holder 5. The operation can be completed quickly without the need for complicated tools or a lot of time. The standardized and modular design makes it easy to replace and maintain the tool, extending the tool's service life. It avoids the wear and tear caused by direct installation and disassembly with bolts over a long period of use.

[0032] Example 2

[0033] Please see Figure 1 and Figure 3As shown in the first embodiment, as another implementation of this utility model, the tool holder 5 has a movable cavity 13 at its end. A connecting shaft 14 is installed on the inner wall of the movable cavity 13. A first blade 15 is installed on the outer surface of the connecting shaft 14. A limiting block 16 is installed on the upper end face of the tool holder 5. A first bolt 17 is installed inside the limiting block 16. A connecting groove block 18 is installed on the side wall of the tool holder 5. A second blade 19 is installed inside the connecting groove block 18. A second bolt 20 is provided on the side wall of the connecting groove block 18.

[0034] Furthermore, the first blade 15 forms a rotating structure with the movable cavity 13 via the connecting shaft 14.

[0035] Furthermore, the limiting blocks 16 are configured in two sets, which are symmetrically distributed about the blade holder 5. The first blade 15 is rotatably connected to the movable cavity 13 via the connecting shaft 14. When the first blade 15 is in contact with the lower end face of the limiting block 16, the first bolt 17 is rotated to fasten the first blade 15. Since the limiting blocks 16 are configured in two sets, the angle of the first blade 15 can be adjusted by installing the second set of limiting blocks 16. This allows for better adaptation to different operational needs, reduces resistance between the blade and the soil, makes the tiller operate more smoothly, reduces energy consumption and mechanical wear, improves the adaptability and flexibility of the tiller, and extends its service life.

[0036] Furthermore, the second blade 19 forms a locking structure with the tool holder 5 through the connecting groove block 18, and the second blade 19 forms a detachable structure with the connecting groove block 18 through the second bolt 20. The second blade 19 is evenly distributed and installed along the side wall of the tool holder 5 through the connecting groove block 18 and the second bolt 20, which can make the soil more effectively tilled, enhance the operation effect, and improve efficiency.

[0037] The working principle is as follows: First, the tool holder 5 is engaged with the mounting base 2 through the mounting groove 3, mounting rod 4, and mounting hole 6. Then, the mounting plate 8 is engaged with the mounting base 2 through the positioning hole 10 and positioning rod 7. The mounting block 9 engages and presses the mounting groove 3, and the tool holder 5 is connected to the positioning rod 7 through the connecting hole 11, thus securing the tool holder 5 inside the mounting groove 3. Rotating the locking screw 12 allows for the installation and removal of the tool holder 5. This allows for quick operation without the need for complex tools or a lot of time. The standardized and modular design makes it easy to replace and maintain the tool, extending its service life and avoiding the wear and tear caused by direct bolt installation and removal over long-term use.

[0038] Finally, the first blade 15 is rotatably connected to the movable cavity 13 via the connecting shaft 14. When the first blade 15 is in contact with the lower end face of the limiting block 16, the first bolt 17 is rotated to fasten the first blade 15. The limiting blocks 16 are set in two sets. The angle of the first blade 15 is adjusted and installed with the second set of limiting blocks 16 to adjust the angle of the first blade 15. This can better adapt to different operating needs, reduce the resistance between the blade and the soil, make the micro-tiller operate more smoothly, reduce energy consumption and mechanical wear, improve the adaptability and flexibility of the micro-tiller, and extend its service life. The second blade 19 is evenly distributed and installed along the side wall of the blade bracket 5 via the connecting groove block 18 and the second bolt 20, which can make the soil more effectively tilled, enhance the working effect, and improve efficiency.
