PROTECTIVE HOUSING, HOPPER DRIVING DEVICE, AND COMBINED SCALES
Document Type and Number:
WIPO Patent Application WO/2023/045159
Kind Code:
A1
Abstract:
A protective housing, comprising a box body (100), an outer cover (200) and a connecting assembly (300), wherein the box body (100) can accommodate a driving element (410); the outer cover (200) can accommodate the box body (100); and the connecting assembly (300) can fix other parts on the outer cover (200). By using the solution of accommodating the box body (100) by means of the outer cover (200), the outer cover (200) directly accommodates the box body (100), so that there is no included angle gap between the box body (100) and the outer cover (200), thereby preventing materials from remaining on the protective housing; in addition, when the outside of the protective housing is cleaned, it is difficult for a water flow to enter a first accommodating cavity (110) due to the protection of the outer cover (200). Furthermore, a mounting plate (310) of the connecting assembly (300) is arranged on a first side plate (220), a second side plate (230) and a third side plate (240), and when the mounting plate (310) is fixed to the side faces by means of fasteners (320), the orientation of the fasteners (320) is not parallel to the axis direction of a first through hole (130) and the axis direction of a second through hole (221), such that the fasteners (320) can be sufficiently prevented from loosening or falling off. Further provided are a hopper driving device for the protective housing, and a combined scales.
