Description

Technical Field

[0001] This utility model relates to the field of farmland tillage and leveling technology, and in particular to an integrated farmland tillage and leveling operation device. Background Technology

[0002] The integrated farmland tillage and leveling operation device is a mechanical equipment that combines tillage and leveling functions. Its tillage part uses plows or rotary tillers to turn and loosen the farmland soil, break up the plow pan, bury weeds and stubble, or break and stir the soil. The leveling part uses scrapers, harrow teeth, or rollers to ensure the farmland surface is flat. This not only improves soil structure and facilitates even water distribution as in the past when they were operated separately, but also saves time and labor by completing two key agronomic steps in one operation. It also avoids soil disturbance from the outside world, thus ensuring the quality of operation. It is of great significance in agricultural production and can help farmers carry out land preparation work more efficiently during the planting season.

[0003] When the integrated farmland tillage and leveling equipment currently in use is working, the rotary tiller is started first. Its power transmission system drives the rotary tiller shaft to rotate at high speed. The rotary tiller blades are arranged in a spiral shape and cut into the paddy field soil. By throwing the soil backward, it achieves cutting, crushing and agitation. At the same time, the depth of rotary tillage can be adjusted to about 12-18 cm with the help of the depth limiting wheel, laying the foundation for subsequent operations. Then, the paddy field leveler located behind the rotary tiller starts to operate. The scraper scrapes the soil on the high ground of the rotary tilled soil surface to the low ground to reduce the height difference, while the rake teeth further comb the soil, break up larger soil clods and mix weeds and stubble into the soil, so that the soil particles are evenly distributed, and finally create suitable seedbed conditions for rice planting.

[0004] While the aforementioned device enables tilling and leveling of farmland, the rotary tillers are prone to damage from hard objects and entanglement with weeds during operation. Therefore, regular replacement and maintenance of the rotary tillers are necessary to ensure smooth tilling. Currently, the rotary tillers are generally fixed to the drive shaft by welding, making replacement and maintenance of the rotary tillers quite troublesome. To address these issues, an integrated tilling and leveling device for farmland is proposed. Utility Model Content

Obviously, the embodiments described 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.

[0033] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an integrated farmland tillage and leveling device, comprising a fixed frame 1, a connecting plate 11 fixedly connected to the side of the fixed frame 1, a flipping component installed on the side of the connecting plate 11, a drive shaft 15 rotatably connected inside the fixed frame 1, and rotary tillage blades 9 and 10 mounted on the outer periphery of the drive shaft 15. When the drive shaft 15 rotates, it drives the rotary tillage blades 9 and 10 to rotate. A disassembly component is provided inside the drive shaft 15; the disassembly component includes a pull rod 16, a locking block 18 fixedly connected to one end of the pull rod 16, and a spring 17 fixedly connected to the side of the locking block 18. When the pull rod 16 moves, it will drive the locking block 18 to move, thereby causing the spring 17 to contract under force. The top of the rotary tiller blade 9 is fixedly connected to the connecting block 19, which is engaged with the locking block 18. When the locking block 18 is disengaged from the connecting block 19, the rotary tiller blade 9 and the rotary tiller blade 10 can be disassembled, which facilitates the maintenance and replacement of the rotary tiller blade 9 and the rotary tiller blade 10. During installation, when the pull rod 16 is released, the tension generated by the return of the spring 17 will cause the locking block 18 to engage with the connecting block 19, thereby completing the installation of the rotary tiller blade 9 and the rotary tiller blade 10. The operation is convenient and improves work efficiency.

[0034] Reference Figure 1 Figure 2 and Figure 5The flipping assembly includes a leveling plate 4 and a leveling plate 5. The sides of the leveling plate 4 and the leveling plate 5 are fixedly connected to the sides of the connecting plate 11. Under the action of the leveling plate 4 and the leveling plate 5, the tilled farmland can be leveled, improving work efficiency. The side of the leveling plate 25 is fixedly connected to the connecting shaft 12 and the connecting shaft 20. The side of the leveling plate 4 is fixedly connected to the connecting shaft 32. The outer periphery of the connecting shaft 12 is rotatably connected to the hydraulic rod 13, and the outer periphery of the connecting shaft 20 is rotatably connected to the connecting rod 12. 1. Connecting rod 23 is fixedly connected to the outer periphery of connecting shaft 3 22. The output end of hydraulic rod 13 is rotatably connected to the interior of connecting rod 1 21 and connecting rod 23. When hydraulic rod 13 works, it will drive connecting shaft 3 22 and connecting rod 23 to move through connecting rod 1 21 and connecting shaft 2 20, thereby driving flat plate 1 4 to flip and fold parallel to flat plate 2 5 under the action of connecting shaft 1 12. This reduces the footprint of the device without affecting work efficiency and improves the convenience of the device.

[0035] Reference Figures 1-3 A fixing block 2 is fixedly connected to the side of the fixing frame 1. A motor 3 is fixedly connected inside the fixing block 2. The output end of the motor 3 is fixedly connected to one end of the transmission shaft 15. When the motor 3 works, it drives the transmission shaft 15 to rotate, thereby driving the rotary tiller blades 9 and 10 to rotate, thus tilling the farmland. A fixing block 6 is fixedly connected to the top of the fixing frame 1. A connecting column 7 is fixedly connected to the side of the fixing block 6. A connecting block 8 is fixedly connected to the outer periphery of the connecting column 7. Under the action of the fixing block 6 and the connecting column 7, the entire device can be moved by the connecting block 8. The leveling plate 4 and the leveling plate The bottom of each of the two plates 5 is provided with a leveling groove 14, which improves the leveling effect of the tilled farmland. There are two leveling plates 4, which are installed on both sides of the leveling plate 5, greatly increasing the area of ​​the tilled farmland and greatly improving work efficiency. There are multiple rotary tillers 9 and 10, which are all locked inside the drive shaft 15. The simultaneous operation of multiple rotary tillers 9 and 10 improves the tilling effect of the farmland. There are two hydraulic rods 13, which are used to drive the two leveling plates 4 to rotate, thereby realizing the simultaneous folding of the two leveling plates 4.

[0036] Working principle: First, when replacing or maintaining rotary tiller blades 1-9 and 10-10, pulling the lever 16 outward will move the locking block 18, and the spring 17 will contract under force. When the locking block 18 moves, it will disengage from the connecting block 19, thus enabling the disassembly of rotary tiller blades 1-9 and 10-10. During installation, releasing the lever 16 will cause the locking block 18 to engage with the connecting block 19 under the action of the spring 17 returning to its original position, thus facilitating the replacement and maintenance of rotary tiller blades 1-9 and 10-10. When the hydraulic rod 13 is in operation, the connecting rod 21 will rotate around the outer circumference of the connecting shaft 20, and the connecting shaft 22 will rotate through the connecting rod 23, thereby causing the leveling plate 25 to rotate, thus reducing the area occupied by the device when it is not in operation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
