The invention discloses an automatic dried dark plum processing device, which comprises an outer shell (1), a pulp removal drum (2), a first motor (3), a cam brush (4), a second motor (5), a small gear (6), a large gear (7) and a first fixing shaft (9). The outer shell (1) comprises an outer shell body (101), supporting columns (102), a positioning ring (103) and a core outlet passage (105). The automatic dried dark plum processing device is capable of removing cores and pulp of dried dark plums and grinding and drying the pulp of the dark plums. The automatic dried dark plum processing devicehas advantages of high operating efficiency, functional completeness, small integral size, convenience in transporting and moving, stability in pulp removal and high efficiency.

The invention relates to a fixed battery quick changing mechanism for an electric vehicle and overcomes the defect of inconvenience in replacing a battery due to an upward battery entrance and exit port in the existing battery frame. The fixed battery quick changing mechanism for the electric vehicle comprises a battery frame connected with a chassis frame of the electric vehicle. The battery frame is positioned below the chassis frame; a plurality of accommodating cavities for placing battery packs are arranged inside the battery frame; the lateral surface of the battery frame is open to form entrance and exit ports corresponding to the accommodating cavities; and battery frame covers capable of being opened and locked are arranged at the positions of the entrance and exit ports. The battery frame is fixed together with the chassis frame of the vehicle, so that after the batteries are arranged in the battery frame, the stability of the batteries can be improved and the batteries have low vibration; the battery fame is positioned below the chassis frame and cannot block the batteries from entering and exiting the battery frame, so that the batteries are convenient to replace; the battery entrance and exit ports of the battery frame are arranged at the side edges and below the chassis frame, so that the frame cannot block the entrance and exit ports and the batteries can be replaced by the entrance and exit ports; and the fixed battery quick changing mechanism for the electric vehicle has simple structure, is convenient to install and cannot occupy more space.

The invention relates to the technical field of steel shot production, and discloses a steel shot sorting device. The steel shot sorting device comprises a shell, a feeding hopper and a discharging pipe. The shell is divided by a supporting frame into an upper cavity and a lower cavity. Screens are arranged at the bottom of the upper cavity, the hole diameter of meshes is sequentially reduced fromthe feeding pipe direction to the discharging pipe direction, and the upper ends, in the steel shot feeding direction, of the meshes are connected with hard balls. A plurality of collecting frames are arranged in the lower cavity, and a material collecting frame is arranged between every two adjacent collecting frames. An intermittent magnet material sucking mechanism is arranged between every two adjacent screens, wherein a material sucking pipe is arranged between the intermittent magnet material sucking mechanism and the next adjacent screen, the lower end of the material sucking pipe penetrates the supporting frame and communicates with the bottom of the corresponding material collecting frame. The material collecting frames are located in front of the intermittent magnet material sucking mechanism, the side wall of the part, located on the upper cavity, of the material sucking pipe is connected with a spraying pipe, the spraying pipe is connected with an induced draft fan, and the free end of the spraying pipe faces the next screen. According to the steel shot sorting device, large steel shots are prevented from blocking the meshes by changing the motion direction of the large steel shots, and small steel shots conveniently pass through the meshes.

The invention discloses a rail vehicle roof drainage protection structure, which includes a protective cover and several mounting parts. A water leakage hole is opened on the part, the mounting part is installed on the roof, and the connecting part extends downwards and is connected with the mounting part. The invention further discloses a rail vehicle roof drainage box, which includes a drainage box body and a drain pipe arranged under the drainage box body, and also includes the above-mentioned rail vehicle roof drainage protection structure, the protection part is located in the drainage box Above the body, the connecting part is located outside the drainage box. The invention has the advantages of being able to prevent sundries from falling into the drainage box, and avoiding obstruction of sundries to cause poor drainage, and the like.

An endoscope system, comprising an endoscope (2) having pipeline opening parts (23 to 26)(pipeline tip parts (40a, 43a, 45a) and a ventilation part (37) as a steam admission port, and a storage case (34) having a tray (35) storing the endoscope (2) in a specified state. A restriction part (49) storing and restricting the endoscope (2) in a recessed part is formed in the tray (35). The restriction part (49) comprises first to fourth restriction area parts (49a to 49d) corresponding to the opening parts of the pipeline opening parts (23 to 26) (40a, 43a, 45a) and the ventilation part (37). These first to fourth restriction area parts (49a to 49d) are formed to have clearances (space portions) (49A to 49D) with areas larger than the cross sectional areas of the opening parts.
