The invention relates to a spraying machine, which includes a cab, a cab lifting device, a variable wheel base assembly, a chassis power system, a spraying frame lifting device, a spray rod assembly, a medicine box assembly, a wheel assembly, and a vehicle hydraulic system , the cab lifting device includes the cab upper parallel rod, the cab lifting cylinder, the cab lateral stabilizer bar, the cab lifting fixed frame, the cab lower parallel rod and the cab lifting mobile frame; the cab upper parallel rod and the cab lower The parallel rods are two rods of equal length, one end of which is hinged with the cab's lifting and fixing frame, and the other end is hinged with the cab's lifting and moving frame; Hinged, the cab can be raised and lowered by the expansion and contraction of the oil cylinder. The invention is a hydraulic self-propelled type, and the wheel base can be adjusted to adapt to the ridge distance of different crops, and can apply pesticides in a large area, and the height of the spray boom can be adjusted according to the height change of the crops, and the steering is flexible.

The invention discloses a bridge arch rib hoisting and supporting bracket integrated construction device which comprises a base, a lifting frame is fixedly connected to the top end of the base, a first pneumatic push rod is fixedly connected to the inner wall of the lifting frame, a moving block is welded to the output end of the first pneumatic push rod, and a moving rod penetrates through the interior of the moving block; and first limiting grooves are formed in two ends of the moving rod and located in the inner wall of the lifting frame. According to the bridge arch rib hoisting and supporting bracket integrated construction device, by arranging a lifting column, in the lifting frame, the first pneumatic push rod works to drive the moving block to move, and the moving block drives the first lifting rod to move along the first limiting groove through the moving rod; the rotating angle of the first lifting rod is 60 degrees, the first lifting rod drives the second lifting column to move along a second limiting groove through the lifting column, the rotating angle of the second lifting rod is 60 degrees, and lifting operation of the lifting frame is achieved through relative movement of the first lifting rod and the second lifting rod.

The invention discloses a telescopic heat radiation sound box, which comprises a base, wherein a plurality of universal wheels are arranged at the bottom of the base; a braking mechanism is arranged on the universal wheels; a fixing plate is sleeved on the top of the outer wall of the base; a plurality of first hydraulic cylinders are arranged at the bottom of the fixing plate; an auxiliary plateis sleeved under the fixing plate at the outer side of the base; an outer box body is arranged on the top of the base; a sound box body is arranged inside the outer box body in a matched way; a waterstorage layer is arranged at the inner wall of the outer box body; a heat radiation layer is arranged on the outer wall of the sound box body; a plurality of water conveying pipes are arranged on thetop of the inner side of the water storage layer; a plurality of second hydraulic cylinders are arranged on the top of the fixing plate; regulating chambers are symmetrically arranged at the two sidesinside the water storage layer; a rotating rod, a first gear, a second gear, a second movable rod, a second rack, a push plate, a first movable rod, a first rack and a connecting block are horizontally arranged inside the regulating chamber; a first fixing block and a second fixing block are arranged on the outer wall of the heat radiation layer. The sound box has the advantages that the use is convenient and fast; the stability is high; the telescopic effects can be realized; the heat radiation effect cannot be influenced in the telescopic process.
