The invention provides a toad-eating pill drying and sorting device. The toad-eating pill drying and sorting device solves the problems that existing toad-eating pills are uneven in drying and cannot be quickly dried during drying, and the pill sorting effect is poor during sealed bottling after drying. Comprising a heat preservation box body, a drying chamber is fixedly connected to the top end of the heat preservation box body, the outer side of the drying chamber is movably connected with a heat preservation box door through a hinge, a cantilever rod is fixedly connected to the middle of the top end in the drying chamber, an electric sliding block is slidably connected to the cantilever rod, and an electric telescopic rod is fixedly connected to the bottom end of the electric sliding block; a scraping plate is fixedly connected to the bottom end of the electric telescopic rod, a supporting rod is fixedly connected to the position, located below the cantilever rod, of one side of the inner wall of the heat preservation box body, an objective table is fixedly connected to the end, away from the heat preservation box body, of the supporting rod, and an objective plate is movably connected to the bottom of the objective table. The device is exquisite in structure and has very high practicability.

An experimental system and method for vibration grading, drying and quality improving of low-rank coal belong to drying and quality improving systems and methods of the low-rank coal. The system is formed by a vibration grading barrel, a grading barrel support, a multi-screening-face mechanism, a grading barrel exciter, a hot smoke input pipeline at the upper portion of a barrel body, a discharging port in the lower portion of the barrel body and a hot smoke replenishing pipeline outside the barrel body, wherein the multi-screening-face mechanism is arranged inside the barrel body. Raw low-rank coal is added into vibration grading drying barrels from the upper portion, pre-grading is carried out by the grading drying barrels under the effect of the exciter, the calibers of screening faces are reduced from top to bottom, the pre-graded low-rank coal forms material layers on the screening faces with different calibers, high temperature hot smoke enters the drying barrels from the upper portion of the barrel body and is in contact with particles of the largest fraction, a coal sample in a vibrating screen is dried, and a screening barrel continuously vibrates to keep the materials loose. The temperature is reduced after the hot smoke passes through the screening face, the hot smoke enters the lower layer of the screening barrel to dry the particles of the next fraction and so on. Finally, the particles of the smallest fraction are discharged into a tail gas separating device along with cooled smoke tail gas.

The invention discloses a double pushing device for a grain dryer. The double pushing device includes an input shaft, an eccentric mechanism, a control mechanism, a transmission mechanism and an output shaft; the eccentric mechanism is installed on the input shaft through a key, The eccentric mechanism and the transmission mechanism are rotatably connected by bolts, the control mechanism and the transmission mechanism are rotatably connected by bolts, and the transmission mechanism is installed on the output shaft through a key; the double pushing device includes two sets of eccentric mechanisms, a control mechanism and Transmission mechanism; the rotation of each set of eccentric mechanisms will produce two reciprocating horizontal output driving strokes; the control mechanism controls the output rotation of the output shaft through the transmission mechanism by controlling the length of the reciprocating horizontal output driving stroke of the eccentric mechanism. The structure design of the double pushing device of the present invention is simple and reasonable, easy to operate, high in pushing frequency, adjustable in pushing stroke, and effectively improves the drying effect of the grain dryer.
