The invention discloses a convenient-to-operate multifunctional punching and shearing machine with high shearing quality and a punching and shearing method thereof, and belongs to the technical field of machining equipment. The multifunctional punching and shearing machine provided by the invention comprises a knife board matching mechanism, wherein the knife board matching mechanism comprises a knife board matching eccentric shaft, wherein the knife board matching eccentric shaft is provided with an outer fixing plate, a first concentric section, a second eccentric section and a third concentric section sequentially; the knife board matching eccentric shaft transversely penetrates a machine body and is fixed to a wallboard of the machine body through the outer fixing plate; and knife boards are connected with the second eccentric section of the knife board matching eccentric shaft through a connecting plate. The multifunctional punching and shearing machine enables the knife board of a moveable knife to rotate around an elliptic radian and the rotation by the method can guarantee that the knife board of the moveable knife and a knife board of a static knife achieve position matching, so that a knife edge of the moveable knife and a knife edge of the static knife can be matched; the method is implemented once for all, that is, mismatching is not liable to occur when blades are changed again after one-time adjustment, so the use of customers is greatly facilitated.

The invention discloses a multifunctional hydraulic combined punching and shearing machine and a punching and shearing method thereof, and belongs to the technical field of mechanical processing equipment. The multifunctional hydraulic combined punching and shearing machine comprises a material pressing mechanism, a lower die base pressing mechanism, a rear material blocking mechanism, an oil cylinder fixing mechanism and a cutter plate matching mechanism, wherein a hydraulic oil cylinder in the oil cylinder fixing mechanism is connected with a punching and shearing machine body through second fastening bolts; contact surfaces of the hydraulic oil cylinder and the punching and shearing machine body are oblique wedge surfaces that are matched pairwise; a cutter plate in the cutter plate matching mechanism is connected with an eccentric shaft; and by rotating the eccentric shaft, a moving cutter plate is matched with a static cutter plate. According to the multifunctional hydraulic combined punching and shearing machine and the punching and shearing method, the defects of the conventional punching and shearing machine are overcome, the use effect of the multifunctional hydraulic combined punching and shearing machine is improved, the modification cost of the conventional punching and shearing machine is low, and economic returns are good.

The invention discloses a conveying device for improving the conveying efficiency of massive ore or coal. The conveying device comprises a conveyor belt, a conveyor belt V-shaped bracket, stop plates,a stop plate conveyor belt and a conveyor belt guide rail bracket; the conveyor belt is laid on the conveyor belt V-shaped bracket in a V shape, and the V-shaped conveyor belt is provided with two conveying sides; and when the stop plates are ready to be taken away from the upper part of the conveyor belt by the stop plate conveyor belt, limiting columns under the stop plates can slide from a limiting slot to a V-shaped limiting slot, and then can be separated from the V-shaped limiting slot, so that the stop plates can rotate around hinge pins, and at this time, the stop plates are close tothe stop plate conveyor belt to be folded through limiting by a limiting plate, thus, the stop plates basically do not occupy the arrangement space of the conveying device, and the conveying device has the practical value. The conveying device solves the problem that when the massive coal or ore is conveyed by the V-shaped conveyor belt with an included angle, stop plates cannot be arranged on theconveyor belt, so that the conveying efficiency of the conveyor belt is low and potential safety hazards exist.

The invention discloses a hinged dumper container assembly, and loading and unloading methods thereof. The container assembly comprises a rear frame and a container, wherein the rear frame comprises a rear frame longitudinal beam assembly, a frame anti-torsion tube, a rear frame lifting seat, a lower hinge seat, a lower bolt seat and a hinge body bearing; the container comprises a bottom plate, a rear tilted plate, a left side plate, a right side plate and a front plate, a left longitudinal beam and a right longitudinal beam are arranged on the left side plate and the right side plate respectively, a left lifting support seat and a right lifting support seat bulging out of the left longitudinal beam and the right longitudinal beam are arranged on the left longitudinal beam and the right longitudinal beam respectively, and an upper hinge seat and an upper bolt seat are arranged at the bottom of the container. The loading method is as follows: returning the container, and loading materials in the container; the unloading method is as follows: turning the container by a lifting oil cylinder, and when the container is turned to a certain position, connecting the upper bolt seat with the lower bolt seat by a bolt; during the turnover process of the container, the materials are detached from the container. The container assembly, and the loading and unloading methods thereof disclosed by the invention are capable of improving the anti-torsion capacity of the frame, improving the bearing capacity and strength of the lifting support seat realizing location for the container, and improving the safety performance of loading and unloading.
