Problems solved by technology
In order to ensure uniform application of pesticides and improve the effective utilization of pesticides, all nozzles on the truss are kept at the same height as the ground. The end droops, causing the mist pattern of the liquid medicine to be disordered, and even causing the spray boom to touch the ground and be damaged
Traditional cylindrical pins are mostly used for the hinge connection of existing trusses, and the relative angle between trusses cannot be adjusted after the trusses droop

Embodiment Construction
[0021] The present invention is described in detail below in conjunction with accompanying drawing:
[0022] Such as figure 1 , 2 , 3, a boom sprayer truss eccentric cone hinge leveling mechanism 1, it includes:
[0023] The upper and lower two eccentric conical leveling hinges, the leveling hinges are installed between the trusses, and the coaxial ones are installed between the trusses, and the two coordinate adjustments to achieve leveling;
[0024] The eccentric conical leveling hinge includes an upper connecting plate 4, a lower connecting plate 6, an eccentric conical hinge pin 5, a nut 2, and a gasket 3;
[0025] Among them, the eccentric conical hinge pin 5 includes from top to bottom the thick-end threaded shaft section II, the thick-end conical positioning shaft section III, the collar IV, the thin-end conical positioning shaft section V, the circumferential oil groove VII, and the thick-end threaded shaft section II , the inner hexagonal hole I, the thick-end coni...

The invention discloses an eccentric conical leveling mechanism for a folding truss of a boom sprayer. The eccentric conical leveling mechanism for the folding truss of the boom sprayer comprises an upper eccentric conical leveling mechanism and a lower eccentric conical leveling mechanism which are the same, and an eccentric conical leveling hinge comprises an upper connecting plate 4, a lower connecting plate 6, an eccentric conical hinge pin 5, a nut 2 and a gasket 3; and the eccentric conical hinge pin 5 comprises a thick-end threaded shaft section 8, a thick-end conical positioning shaft section 9, a shaft ring 10, a thin-end conical positioning shaft section 11 and a thin-end threaded shaft section 13 from top to bottom, the thick-end threaded shaft section 8, an inner hexagonal hole 7, the thick-end conical positioning shaft section 9 and the shaft ring 10 have the same axis, the thin-end conical positioning shaft section 11, a circumferential oil groove 12 and the thin-end threaded shaft section 13 have the same axis, and an eccentric distance is formed between the two axes. According to the mechanism, the axis distance between the upper connecting plate and the lower connecting plate of the upper eccentric conical leveling hinge and the lower eccentric conical leveling hinge is cooperatively adjusted, so that the sprayer truss can keep the uniform height after being unfolded, the uniformity of pesticide spraying is improved, and the mechanism better adapts to the operation mode of field pesticide application.
Description
technical field [0001] The invention relates to the field of equipment related to farmland spraying, and mainly relates to a truss eccentric conical hinge leveling mechanism of a boom sprayer. Background technique [0002] At present, the truss of the boom sprayer is generally 10m-26m, and the longest can reach 42m. In order to reduce the volume of the machine body and facilitate transportation, the truss is folded in multiple sections in a hinged manner. In order to ensure uniform application of pesticides and improve the effective utilization of pesticides, all nozzles on the truss are kept at the same height as the ground. However, due to factors such as assembly accuracy, welding deformation, and self-weight, the gap at the hinge of the truss gradually increases during use, causing The end droops, causing the mist pattern of the liquid medicine to be disordered, and even causing the spray boom to touch the ground and be damaged. Traditional cylindrical pins are mostly u...
