Description

Technical Field

[0001] The utility model relates to the technical field of anti-tilt harvester, in particular to an anti-tilt structure for a tobacco harvester used in hilly and mountainous areas. Background Art

[0002] Tobacco prefers warm, sunny environments. It is not cold-tolerant but relatively heat-tolerant. It prefers fertile, deep, well-drained soil. It primarily propagates by division and sowing. Besides being smoked as cigarettes, dry tobacco, pipe tobacco, and cigars, tobacco also has a variety of medicinal uses. Hilly and mountainous areas offer a natural advantage for producing high-quality, ecologically distinctive tobacco leaves, which are harvested using machine harvesters.

[0003] At present, when the harvester is running in the hilly and mountainous tobacco-growing areas, due to the different slopes of the hilly and mountainous terrain, the harvester has different degrees of inclination when running in the hilly and mountainous tobacco-growing areas. When the harvester is tilted at a large angle, the lack of support and the small size of the harvester are prone to tipping over, posing a safety hazard. Although the large-volume harvester has a certain stability, it is large in size and is inconvenient to operate in the hilly and mountainous tobacco-growing areas. Utility Model Content

The anti-tilt support angle of the harvester body is adjustable, the support anti-tilt is more stable, and the equipment volume is reduced.

[0025] Specifically, the supporting mechanism includes a wheel frame 31, a No. 1 hydraulic cylinder 32 and a support wheel 33. A No. 1 hydraulic cylinder 32 is provided at the bottom of the harvester body 1. The output end of the No. 1 hydraulic cylinder 32 is connected to the wheel frame 31 through a hydraulic rod. A support wheel 33 is provided on the wheel frame 31. The No. 1 hydraulic cylinder 32 pushes the wheel frame 31 and the support wheel 33 to move through the hydraulic rod to adjust the distance between the support wheel 33 and the harvester body 1.

[0026] Furthermore, the wheel frame 31 and the connecting frame 7 are both arranged in a U-shaped structure, and a scraper is provided on the wheel frame 31 on one side of the support wheel 33 and the connecting frame 7 above the anti-tilt roller 8. The scraper scrapes the mud from the support wheel 33 and the anti-tilt roller 8, so that the anti-tilt support state of the support wheel 33 and the anti-tilt roller 8 is stable.

[0027] Furthermore, the rotating mechanism 5 includes a rotating seat 51, a rotating shaft 52 and an actuator. A rotating seat 51 is provided on the top of the No. 2 hydraulic cylinder 6, and rotating shafts 52 are provided on the opposite sides of the rotating seat 51. The rotating seat 51 is rotated by the rotating shaft 52 and is arranged between the two support plates 4. The two support plates 4 are provided with actuators on the side away from each other. The end of the rotating shaft 52 away from the rotating seat 51 passes through the support plate 4 through the shaft hole and is connected to the actuator. The actuator drives the rotating seat 51 between the two support plates 4 to rotate through the rotating shaft 52, so that the No. 2 hydraulic cylinder 6 is tilted and supported on the harvester body 1 for anti-tilt.

[0028] Furthermore, the actuator includes a worm gear 53, a worm 54 and a servo motor 55. The two support plates 4 are provided with a worm gear 53 and a worm 54 on the side away from each other through a protective box. The end of the rotating shaft 52 away from the rotating seat 51 is connected to the worm gear 53, and the top of the worm 54 is connected to the output end of the servo motor 55 on the protective box through a coupling. The worm gear 53 and the worm 54 are meshed. The servo motor 55 drives the worm 54 and the worm gear 53 meshed with the worm 54 to rotate. The rotating worm gear 53 drives the rotating seat 51 between the two support plates 4 to rotate through the rotating shaft 52. The self-locking characteristics of the meshing of the worm gear 53 and the worm 54 enable the anti-roll support angle to be self-locked and maintain a stable anti-roll support state after adjustment.

[0029] Furthermore, a fixed plate is provided on the top of the No. 2 hydraulic cylinder 6, and a T-shaped structure is set between the No. 2 hydraulic cylinder 6 and the fixed plate. The fixed plate is fixed to the rotating seat 51 by bolts. The No. 2 hydraulic cylinder 6 and the rotating seat 51 can be disassembled and assembled, and the disassembly and assembly are convenient and the fixing is firm.

[0030] The method of using this embodiment is as follows: the No. 1 hydraulic cylinder 32 at the bottom of the harvester body 1 pushes the wheel frame 31 and the support wheel 33 to move through the hydraulic rod, and adjusts the distance between the support wheel 33 and the harvester body 1, so that the support space area of ​​the tobacco harvester can be increased and the stability of the harvester in hilly and mountainous areas can be improved through the support mechanism of the harvester body 1 composed of the wheel frame 31, the No. 1 hydraulic cylinder 32 and the support wheel 33. The support space area is adjustable to avoid the limitation problem of large equipment volume. The driving wheel 2 and the driven wheel 3 on the harvester body 1 are in operation to realize mobile tobacco harvesting. According to the inclination of the ground on which the harvester body 1 is running, the rotation angle of the No. 2 hydraulic cylinder 6 is adjusted by the rotating mechanism 5 on the support plate 4, that is, the servo motor 55 on the protection box drives the worm 54 , the worm wheel 53 engaged with the worm 54 rotates, and the rotating worm wheel 53 drives the rotating seat 51 between the two support plates 4 to rotate through the rotating shaft 52, so that the No. 2 hydraulic cylinder 6 is tilted on the harvester body 1, that is, the No. 2 hydraulic cylinder 6 rotates away from the harvester body 1, and then the No. 2 hydraulic cylinder 6 drives the connecting frame 7 and the anti-tilt roller 8 to move through the hydraulic rod, so that the anti-tilt roller 8 contacts the inclined ground, and the rotation adjustment of the anti-tilt support angle, that is, the anti-tilt support angle of the harvester body 1 is adjustable, so that the support anti-tilt is more stable, and the self-locking characteristics of the engagement of the worm wheel 53 and the worm 54 make it possible to self-lock and maintain a stable anti-tilt support state after the anti-tilt support angle is adjusted, and the harvester is in a non-anti-tilt support state, and the No. 2 hydraulic cylinder 6 and the No. 1 hydraulic cylinder 32 are reset, which reduces the equipment volume and is more practical.

[0031] Example 2

[0032] The structure of the anti-tilt structure of the tobacco harvester in hilly and mountainous areas in this embodiment is basically the same as that of the anti-tilt structure of the tobacco harvester in hilly and mountainous areas in Example 1. The difference is that the anti-tilt system includes a collection module, a processing module, a control module and an execution module (see Figures 1 to 4 The acquisition module collects horizontal data of the harvester body 1 based on the horizontal sensor 9. The output end of the acquisition module is electrically connected to the input end of the control module through the processing module. The output end of the control module is electrically connected to the input ends of the execution module and the alarm module. The execution module includes a servo motor 55, a No. 1 hydraulic cylinder 32, and a No. 2 hydraulic cylinder 6. The alarm module uses the anti-tilt alarm of the alarm on the harvester body 1. The control module is electrically connected to the power supply module and the storage module. The horizontal sensor 9 of the acquisition module collects the inclination data of the ground on which the harvester is operating. The collected data is processed by the processing module and then transmitted to the control module. The control module controls the servo motor 55, the No. 1 hydraulic cylinder 32, and the No. 2 hydraulic cylinder 6 of the execution module based on the received data, that is, the anti-tilt structure on the harvester is easy to control.
