Description

TECHNICAL FIELD

[0001] The utility model belongs to grain processing technical field, especially a grain elevator. BACKGROUND

[0002] Grain is an important resource in human life, and the main function of the grain elevator is to lift the grain from a low place to a high place to realize the vertical conveying of the grain. It can effectively improve the carrying efficiency of the grain, reduce the labor intensity, and provide convenience for the subsequent processing and storage of the grain. The existing grain elevator can meet the basic lifting effect, but cannot perform basic screening on the grain, and the impurities and dust contained in the grain cannot be separated from the grain, which reduces the purity of the grain and pollutes the storage environment.

[0003] After searching, the Chinese patent file (authorized announcement number CN213230195U) discloses a grain elevator, which comprises a shell and a guide plate. A driven roller is arranged at the top of the shell, and a driving roller is arranged at the bottom of the shell. A conveying belt is sleeved on the driving roller and the driven roller. A plurality of hoppers are arranged on the conveying belt at intervals. A discharge plate is hinged to the inner wall of the side of the conveying belt close to the plurality of hoppers. A feeding port is arranged on one side of the bottom of the shell, and a discharging port is arranged on the other side of the top of the shell. The guide plate is arranged outside the shell and connected with the outer wall of the feeding port. A baffle is arranged on both sides of the guide plate. A hydraulic cylinder is arranged on the inner side of the baffle. An activity plate is connected with the piston rod of the hydraulic cylinder. The lower end of the activity plate is hinged to the guide plate. A clamping groove is arranged on the activity plate. A clamping block is movably connected with the clamping groove on the piston rod of the hydraulic cylinder. The grain elevator can effectively avoid the falling of part of the grain during the feeding and discharging process to the bottom of the elevator, and ensure the normal work of the elevator. However, the grain elevator cannot perform basic screening on the grain, and the impurities and dust contained in the grain cannot be separated from the grain, which reduces the purity of the grain and pollutes the storage environment.
