The lifter slicer has the advantage of high bearing capacity.

The invention relates to a traveling mechanism of agricultural machinery and aims to solve the technical problem that the provided traveling mechanism can walk stably in an unmanned state, and the machine frame can do an up-and-down movement, so that the unmanned requirements can be met. The invention adopts the technical scheme that the walking type rice seedling planter traveling mechanism comprises traveling wheels respectively mounted on the left side and the right side of a rice seedling planter and is characterized in that a tail wheel for adjusting the direction is provided; the traveling wheels and the tail wheel are respectively hinged onto a curved bar in a four-bar mechanism, the curved bar is U-shaped, and the left side end parts of the two bar walls of the curved bar are fixed with the wheel shafts of the two traveling wheels respectively; a wheel stand shaft sleeve is fixed at the connecting end of the right sides of the two bar walls of the curved bar; and the wheel stand equipped with the tail wheel can be rotationally inserted in the wheel stand shaft sleeve.

The present invention relates to the field of papermaking, and in particular to a paper core lifting mechanism, which includes a frame, a lifting bracket that can slide up and down on the frame, a V-shaped support frame on the lifting bracket, and a guide on the lifting bracket. Mechanism, the driving mechanism arranged on both sides of the lifting bracket, the frame includes two vertical columns, the columns are provided with sliding grooves that cooperate with the guide mechanism, and the driving mechanism includes A motor, two drive shafts connected with the drive of the motor, a gear arranged on the free end of the drive shaft, and a rack matched with the gears are arranged on the column. It solves the technical problem that the existing paper core feeding is still carried out manually, resulting in low work efficiency and low safety.

The invention relates to a large-scale lifting screen performance machine with a long-span synchronous lifting arm, which is mainly formed by a lifting screen, fixed arms, telescopic arms, a driving mechanism, transmission mechanisms and a balance weight mechanism, wherein the tops of both sides of the lifting screen are fixed to the top ends of the two telescopic arms respectively; the two telescopic arms are arranged in the two fixed arms longitudinally in a lifting way; a middle driving mechanism which corresponds to the top ends of the fixed arms is fixedly arranged on a fixture in the rear of the lifting screen; the synchronous transmission mechanisms are arranged on both sides in the lateral direction of the driving mechanism; the driving mechanism drives the telescopic arms to drive the lifting screen to lift by the transmission mechanisms; and the balance weight mechanism are connected to the bottom ends of the two telescopic arms and the lifting screen commonly. The large-scale lifting screen performance machine has scientific and reasonable structural design, runs stably and is safe and reliable and the design desire of the extra large-scale outdoor lifting screen is realized, so that audiences can enjoy the spectacular scene of lifting large-scale light-emitting diode (LED) display frames slowly at a far distance.

The invention relates to the field of paper making, in particular to a paper core lifting mechanism which comprises a rack, a lifting support arranged on the rack in an up-down sliding mode, a V-shaped supporting frame arranged on the lifting support, a guide mechanism arranged on the lifting support and driving mechanisms arranged on the two sides of the lifting support. The rack comprises two stand columns which are vertically arranged. A sliding groove matched with the guide mechanism is formed in each stand column.
