This invention provides a tall crop harvesting vehicle, which includes a chassis, an upper frame, and harvesting implements. The chassis includes two sets of longitudinal double-section axles arranged symmetrically on the left and right sides, with steerable wheels at both ends of the two sets of longitudinal double-section axles. The upper frame is a gantry frame, with its left and right sides connected to the rocker arms of the two sets of longitudinal double-section axles. A passage for tall crops to pass through is provided in the middle of the upper frame and chassis. The harvesting implements include a lower cutting device, a straightening frame, a conveying device, a leaf stripping device, and a collection bin. The harvesting vehicle can perform the harvesting, conveying, and leaf stripping of tall crops while in motion, greatly improving production efficiency.

The application provides an uplink integrated intelligent bridge building machine and a construction method, which comprises a main beam, a formwork device connected with the main beam, a front guide beam arranged at the front end of the main beam, and a rear guide beam arranged at the rear end of the main beam; the length of the rear guide beam is greater than or equal to the length of one span between bridge piers, and the length of the front guide beam is less than the length of one span between bridge piers; a reinforcing bar binding jig frame is arranged on the rear guide beam and used for binding box girder reinforcing bars; a movable crown block is arranged on the rear guide beam and the main beam, and the crown block is used for hoisting the bound box girder reinforcing bars in the formwork device. The rear guide beam simultaneously serves as the counterweight of the bridge building machine and the reinforcing bar binding and concrete curing section, and the utilization efficiency of the structure is greatly improved. The reinforcing bar binding, concrete pouring and curing can be simultaneously performed, and the efficiency of bridge construction is greatly improved. Moreover, the crown block can directly hoist the box girder reinforcing bars from the rear guide beam to the formwork device of the main beam, and no conversion is needed in the middle, so that the deformation of the box girder reinforcing bars caused by the conversion of the hoisting device is avoided.

The application relates to a conveying device for corrugated paperboards, comprising a conveyor, a feeding station arranged at one end of the conveyor, the feeding station being used for placing the corrugated paperboards, a supporting frame being arranged between the conveyor and the feeding station, a suction mechanism being slidably arranged on the supporting frame, the suction mechanism being used for sucking the corrugated paperboards on the feeding station, a running mechanism being arranged on the supporting frame, a lifting piece being arranged on the running mechanism, the lifting piece and the suction mechanism being used for driving the suction mechanism to lift, the feeding station, the suction mechanism, the lifting piece and the running mechanism are cooperatively used, the suction, transfer and placement operations of the corrugated paperboards can be quickly and continuously completed, the suction mechanism can quickly reach the designated position through the cooperative work of the running mechanism and the lifting piece, the feeding time is shortened, and the overall production efficiency is improved.
