The invention discloses an antiwear belt conveyor which comprises a discharge hopper, a guide device, an impact idler group, a middle frame and a bracket The discharge hopper is arranged above the guide device; the impact idler group is arranged in the guide device; a belt is arranged on the impact idler group; the middle frame is arranged below the impact idler group; and the bracket is arranged below the middle frame The discharge hopper comprises a hopper body, a lining plate and an outlet; the lining plate is arranged in the hopper body; the outlet is arranged below the hopper body; the outlet contracts inwards; and a buffer stand is arranged between the hopper body and the outlet; moreover, a buffer body is in an integrated structure or a split-type structure By adopting the buffer body in the antiwear belt conveyor, a main absorber for material impact energies is transferred, the absorption of a working piece on the material impact energies is reduced, and the purpose of prolonging the service life of the working piece is achieved; and moreover, the antiwear belt conveyor can further reduce the dynamic load of a supporting piece The antiwear belt conveyor reduces the impact and the attrition of materials on the side wall of the hopper and discharges a material flow towards a direction beneficial to the conveyor

Antiwear belt conveyor

The invention discloses a grain warehousing buffer device capable of reducing the grain breakage rate. The device comprises a shell, a rice outlet pipe, a buffer pipe, elastic collision assemblies, adischarge port and a base. The buffer pipe is arranged in the shell, the rice outlet pipe is mounted in the middle position of the upper portion of the shell, the upper portions of the two side wallsof the rice outlet pipe are fixedly welded to the inner wall of the shell, the base is arranged below the shell, the shell and the base are fixedly connected through a buffer device, and the dischargeport is welded to the lower surface of the buffer pipe. The device is characterized in that the elastic collision assemblies are staggered on the side wall of an inner cavity of the buffer pipe, andeach elastic collision assembly comprises an upper fixed base, a first elastic plate, a second elastic plate and a buffer cushion. Energy saving and environmental protection are achieved, the integrity of the grain diameter of rice can be guaranteed, meanwhile, compression and release of air can be achieved through impact force of the rice, cushion protection of rice particles is further achieved,and a large amount of energy is saved.

Coal leakage preventive device of belt conveyor

The utility model relates to an adjustable transferring buffering coal blocking plate with a T-shaped belt. The utility model is a coal blocking device for the T-shaped transferring position of belt conveyers. The utility model is composed of a portal frame and a lower supporting frame. A buffering coal blocking plate facing the upper belt is fixed on the cross beam of the portal frame, and adjustable coal blocking plates are arranged on both sides of the portal frame. A coal blocking cylinder is arranged between the buffering coal blocking plate and the lower belt. The buffering coal blocking plate can be longitudinally and laterally adjusted on the cross beam and the portal frame, the angle can be adjusted by the adjustable coal blocking plates, and the portal frame can be longitudinally and laterally adjusted on the supporting frame. The utility model can solve the problems such as belt bruising, carrying material piling, transport line blocking, etc.
