Abstract

The invention relates to the field of engineering machinery, in particular to a material tank control system, engineering machinery and a material tank control valve. The material tank control systemcomprises a cover opening oil cylinder, a locking oil cylinder and a first control device, the first control device is connected with the cover opening oil cylinder and the locking oil cylinder, and controls the action sequence of the cover opening oil cylinder and the locking oil cylinder, so that the cover opening oil cylinder controls a tank cover to open after locking of a locking piece on thetank cover is unlocked by the locking oil cylinder, and / or, the locking oil cylinder controls the locking piece to lock the tank cover after the tank cover is controlled by the cover opening oil cylinder to close. According to the material tank control system, the functions of unlocking before opening the cover and / or closing the cover before unlocking can be achieved, the misoperation can be effectively prevented, and the work safety is improved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a material tank control system, construction machinery and a material tank control valve. Background technique [0002] In construction machinery such as vacuum suction trucks, tanks are used to store materials. During the working process, operations such as lifting of the tank, falling of the tank, opening and closing of the tank cover and locking of the tank cover will be involved. [0003] The study found that in related technologies, actions such as lifting and lowering of the tank, opening and closing of the tank lid, and locking of the tank lid are controlled separately, and there is no sequence, which may easily cause safety problems such as equipment damage or rollover. Contents of the invention [0004] The invention aims to provide a material tank control system, engineering machinery and material tank control valve to improve work safety. [0005] In order to a...
