Main engine cabin cover of pesticide sprayer

Abstract

The invention discloses a main engine cabin cover of a pesticide sprayer. Four flanges which are evenly distributed in the peripheral direction are integrally formed on an outer edge of a cover body;two adjacent flanges form a smooth transit through a recessed portion; a locking tool is embedded in the center of the cover body; a locking cylinder of the locking tool exceeds a central bottom surface of the cover body downward; a following block is fixed on a lower end of the locking cylinder; the following block is cross-shaped; four suspension ends of the following block are corresponding tofour guide blocks respectively; the four guide blocks are corresponding to four recessed portions of the cover body in a one-to-one manner; each guide block has a locking rod; inner ends of the locking rods are movably connected to the suspension ends of the following block; and outer ends of the locking rods pass through guide holes formed in the guide blocks correspondingly. The invention main engine cabin cover is reasonable in design, is simple in structure, is few in parts, is easy to manufacture and assemble, can effectively reduce the production cost, can ensure the locking reliabilityof the main engine cabin of the main engine cabin cover, is easy to operate, and can save effort.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a main engine cabin cover of a pesticide spraying machine. Background technique [0002] At present, the UAV that sprays pesticides automatically generally includes a main engine cabin, a cantilever and a power cabin, and the opening on the top of the main engine cabin is sealed by the main engine cabin cover. The existing main engine compartment cover is usually connected to the main engine compartment in two ways, one is a flip-lock type, and the other is a snap-fit ​​lock type. Due to the poor reliability of the flip lock type, the snap lock type main engine compartment cover has gradually become the mainstream. [0003] The existing buckle-locking main engine compartment cover is generally locked by turning the lock bar, and the lock bar is reset by the elastic force of the spring. Due to the small parts, there are disadvantages such as difficulty...

AI Technical Summary

Problems solved by technology

Due to the small parts, there are disadvantages such as difficult processing, difficult assembly, high production cost, etc.

In addition, two-point or three-point locking is adopted. On the one hand, multiple locking points must be operated at the same time, which increases the difficulty of operation; on the other hand, the reliability after locking is still insufficient, which may cause the engine compartment The cover is loose or making abnormal noises
