Engineering machinery cover and engineering machinery

Abstract

The present invention provides an engineering machinery cover which can prevent the xenembole at a high level and guarantee the opening area of an air vent. A bottom cover (20)of the engineering machinery cover comprises a cover main body (21) detachably arranged on an opening at the bottom of the machine body of an engineering machinery; an air vent (22) formed for the opening of the cover main body; and a plurality of angular louver boards (23) arranged in the air vent at intervals. Each angular louver board is formed by bending a long-size plate into a steel angle part shape via a central bending part (31) along a length direction, so that an inclined part (32) is formed at one side of the bending part, and another inclined part (33) is arranged at the other side of the bending part. The configuration spacing of the angular louver boards (23) is set as the widths of the projection openings among the angular louver boards which are formed by the projection in a right angle direction along the arrangement direction of the louver boards are less than the minimum clearance between the adjacent angular louver boards.

Description

technical field [0001] The present invention relates to a construction machine cover characterized by a louver structure, and a construction machine provided with the cover. Background technique [0002] Various openings are provided in the bottom of the body of a construction machine such as a hydraulic excavator for inspection, weight reduction, or other purposes of the frame of the construction machine. These various openings provided at the bottom are blocked by the detachable bottom covers on these openings so that foreign matter does not enter the fuselage through these openings, thereby protecting the piping and wiring in the fuselage. [0003] Contrary to the original fuselage protection function, depending on the location of the opening, in order to discharge the cooling and heat dissipation of the engine and working oil to the outside of the fuselage, it is necessary to provide a certain amount of vents on the bottom cover itself. [0004] In this case, constructi...

AI Technical Summary

Problems solved by technology

[0004] In this case, construction machinery mainly used for general civil engineering work is not limited to the following cases, but when the construction machinery is used for demolition, forestry, recycling, etc. The foreign matter may intrude into the fuselage from the air vent of the bottom cover. If these foreign matters enter the fuselage, it may cause damage to the hydraulic piping and electrical wiring in the fuselage, which is not conducive to the protection of the fuselage.
