Tube conveying machine

The invention discloses a tube conveying machine, and relates to the field of mechanical equipment driving. The tube conveying machine comprises a rack, wherein a power device is arranged on the rack, a V-shaped frame which is inverted is arranged on the bottom face of the rack, the two side faces of the V-shaped frame are respectively provided with a driving belt, a V shape is formed by the two driving belts, a movable downward-pressing frame is arranged on the upper portion of the rack, a main driving belt which is vertically placed is arranged on the downward-pressing frame, and the power device is connected with the main driving belt through a driving device. The tube conveying machine has the advantages that material tubes are conveyed through the belts, due to the fact that the belts have high friction coefficients, stability of the conveying speed of the material tubes can be ensured, and the conveying quality of the tubes is improved; stepless adjustment of the speed of conveying the tubes and the speed of withdrawing the tubes can be achieved through control over the pressure and the flow of a hydraulic system, and the charge ratio between the speed of the tubes and material conveying is ensured; control accuracy is high; labor intensity of workers is reduced, working efficiency is improved, and economic benefit is improved.
