[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.
[0023] See also Figure 1-5The present invention provides a technical solution: a floating micro-tillage tillage device, comprising a tillage device body 1, a main frame 4 is arranged on the tillage device body 1, and one end of the main frame 4 is hingedly connected to a movable connecting plate 401, and both sides of the upper end of the main frame 4 are symmetrically provided with inclined pneumatic auxiliary connecting frames 2, and the two ends of the pneumatic auxiliary connecting frames 2 are respectively rotatably connected to the main frame 4 and the movable connecting plate 401 through pins. This structure can assist in connecting the main frame 4 and the movable connecting plate 401 through the pneumatic auxiliary connecting frame 2, so that the movable connecting plate 401 can be moved at a certain angle under the positioning of the main frame 4, thereby reducing the vibration effect generated during the tillage process, ensuring the reliability of the structure of the floating positioning frame 403, and the movable connecting plate 401 is externally connected to the main frame 4 and the movable connecting plate 401. A floating positioning frame 403 is fixed on the side, and limit rods 14 parallel to each other are fixed by bolts evenly spaced inside the floating positioning frame 403, and the limit rods 14 and the floating adjustment frame 404 are movably connected and cooperated. This structure allows the floating adjustment frame 404 to move relative to the floating positioning frame 403 under the limit of the limit rod 14, and the floating adjustment frame 404 is movably engaged with the inner side of the floating positioning frame 403. The floating adjustment frame 404 is a "J"-shaped structure, and a lifting hydraulic cylinder 6 is hingedly fixed to the groove part in the middle of the floating adjustment frame 404. This structure allows the lifting hydraulic cylinder 6 to drive the floating adjustment frame 404 to move, and floating shock-absorbing frames 7 are symmetrically installed on both sides of the lower end of the floating adjustment frame 404, and a floating mounting connected to the floating shock-absorbing frame 7 is provided below the floating positioning frame 403. The bottom of the floating mounting frame 405 is connected with an auxiliary support wheel 8 through a rotating rod structure, and the auxiliary support wheel 8 is located in the middle of the main body 1 of the tillage device. This structure allows the auxiliary support wheel 8 and the main support wheel 12 to form a triangular support structure, and the auxiliary support wheel 8 plays the role of front-end auxiliary support. The movable part of the lifting hydraulic cylinder 6 is connected with the floating positioning frame 403, and the fixed end screw of the lifting hydraulic cylinder 6 is fastened to the floating positioning frame 403. This structure can stabilize the lifting hydraulic cylinder 6 under the positioning of the floating positioning frame 403, and drive the floating adjustment frame 404 to rise and fall under the positioning of the floating positioning frame 403, so as to adjust the position of the rotary tillage knife frame 10, so as to control the tillage depth of the rotary tillage knife frame 10, and at the same time, the rotary tillage knife frame 10 The floating mounting frame 405 can be matched with the floating shock absorbing frame 7 to achieve floating shock absorption within a certain range to ensure the consistency of the tillage operation. The floating shock absorbing frame 7 and the roller shock absorbing frame 13 are both suspension shock absorbing mechanisms composed of existing shock absorbers, springs, and torsion bars. A transmission mechanism 9 is installed on the upper side of the floating mounting frame 405. A handrail 5 is bolted to the main frame 4, and a power supply chassis 3 is installed on the upper part of the main frame 4. The power supply chassis 3 is electrically connected to the transmission mechanism 9. This structure powers the transmission mechanism 9 through the power supply chassis 3. The transmission mechanism 9 is a reduction motor. The rotary tillage blade frame 10 can be driven to rotate through the transmission mechanism 9 to achieve tillage. A shock absorbing plate 402 is bonded and fixed to one side of the movable connecting plate 401 close to the power supply chassis 3.The shock absorbing plate 402 is in contact with the power supply chassis 3. This structure can perform shock absorbing protection on the movable connecting plate 401 through the shock absorbing plate 402. A rotary tiller frame 10 chain-driven by the transmission mechanism 9 is installed below the floating mounting frame 405. A scraper plate 11 is also fixed below the floating mounting frame 405. A scraper groove 1101 corresponding to the position of the rotary tiller is opened on the side of the scraper plate 11. The scraper plate 11 adopts a semi-open cylindrical structure, and the size of the scraper groove 1101 is larger than the size of the rotary tiller. This structure allows the scraper plate 11 to discharge the scraped soil through the open structure. When the rotary tiller frame 10 is driven to rotate through the transmission mechanism 9, the rotary tiller plows the soil, and when the rotary tiller passes through the scraper plate 1 1, most of the soil attached to the rotary tiller is scraped off through the scraping groove 1101 to avoid affecting the tilling process of the rotary tiller. The main support wheel 12 is symmetrically installed below one end of the main frame 4 close to the handrail 5, and the main support wheel 12 is bolted to the bottom of the main frame 4 with a roller shock absorber frame 13. The handrail 5 of this structure is used for the rotation and pushing operation of the tillage device body 1. The main support wheel 12 makes the tillage device body 1 uniform and reliable. The support structure makes it easy to push the tillage device body 1. The roller shock absorber frame 13 plays a shock absorbing role for the main support wheel 12. By improving the stability of the tillage device body 1, the service life of the tillage device body 1 can be extended. The power supply chassis 3 also plays an electronic control role for the lifting hydraulic cylinder 6.
[0024] Working principle: When using the floating micro-tillage tillage device, firstly, when the tillage device body 1 is used for tillage, the main frame 4 is pushed by the handrail 5, and the main frame 4 is moved by the auxiliary support wheel 8 and the main support wheel 12. The main support wheel 12 and the auxiliary support wheel 8 are respectively subjected to floating shock absorption within a certain range through the roller shock absorption frame 13 and the floating shock absorption frame 7. When the tillage is carried out, the floating adjustment frame 404 is controlled to descend by the lifting hydraulic cylinder 6. The floating adjustment frame 404 moves relative to the floating positioning frame 403 through the limit rod 14. The position of the floating mounting frame 405 is adjusted by the floating shock absorption frame 7 to control the floating adjustment frame 404 to move relative to the floating positioning frame 403. The tillage depth is controlled, and the transmission mechanism 9 is started again, so that the transmission mechanism 9 drives the rotary tillage blade frame 10 to rotate to realize the tillage process. When the rotary tillage blade passes through the scraper plate 11, the attached soil is scraped off through the scraper groove 1101, and the soil falls through the opening structure of the scraper plate 11. During the tillage process, the movable connecting plate 401 rotates relative to the main frame 4, and the movable connecting plate 401 is connected to the main frame 4 through the pneumatic auxiliary connecting frame 2. The shock-absorbing plate 402 is used for the shock-absorbing treatment of the movable connecting plate 401 and the power supply chassis 3, ensuring the reliability of the overall structure of the floating positioning frame 403, allowing the efficient use of the tillage device body 1, thereby completing a series of tasks.
