The invention relates to a conveying, turning and unloading device used for fruit grading, which at least comprises a weighing holder, a clamping seat, a lock catch, a roller wheel and a fruit supporting plate, wherein the weighing holder is installed on the clamping seat by two irregular bosses and positioned by the lock catch; the lock catch is installed on the weighing holder by two circular pin shafts and installed on the clamping seat by a clamping groove; the clamping groove is contacted with the clamping seat by adopting an inclined surface; the roller wheel slides up and down in an elongated slot of the weighing holder by the pin shaft; the fruit supporting plate is clamped on the weighing holder by the two circular bosses, and can swing around boss axis; and the clamping seat is provided with two chain mounting holes used for realizing the connection with a grading chain. The device is reasonable in structure and convenient in usage, avoids handling mark during transition from a photoelectric function section to a weighing function section when in online fruit grading, ensures intact fruits, is beneficial to reducing fruit damage rate, simultaneously can realize the integration of fruit conveying, turning and unloading, has the characteristics of automatic operation, endurableness, saved energy and the like.

The invention relates to a children automobile seat and a combination of a headrest and shoulder belt pads of the children automobile seat. The children automobile seat comprises an automobile seat body, the headrest arranged on the automobile seat body, safety belts arranged on the automobile seat body, and should belt pads of which the amount corresponds to that of the safety belts, wherein the headrest is provided with fore and after penetrated through holes of which the amount corresponds to that of the shoulder belt pads; each shoulder belt pad comprises a pad body combined with the safety belts, a connecting belt and a limiting piece; one end of the connecting belt is connected with the pad body, and the other end is connected with the limiting piece; the limiting piece can transversely pass through the through holes together with the other end of the connecting belt; and after passing through the through holes, the limiting piece can longitudinally press against the other side of the headrest.

A mobile system for improving the picking and preliminary processing of apples, citrus, stone fruit and the like is disclosed and claimed. The system comprises a mobile chassis upon which can be mounted picking stations, pneumatic tube transport subsystems, receiving and conveying subsystems, object scanning subsystems, cull diverter subsystems, labeling subsystems, and subsystems for relatively gently placing the objects in a predetermined location in a receiving bin. The system can also include a subsystem for gently placing diverted objects in a receiving bin.

The invention discloses an electromagnetic clamp, which comprises a base, and a left clamping part and a right clamping part which are detachably engaged with each other are oppositely arranged on the base, and the left clamping part and the right clamping part are joined together It has an accommodating space for accommodating workpieces; the left clamping part is detachably connected to the base, and the right clamping part is slidingly connected to the base; the left clamping part and the right clamping part Each of the holding parts has a cavity, and a controller is arranged in the cavity, and a first electromagnet is set in the cavity of the left clamping part, and a first electromagnet is set in the cavity of the right clamping part. There is a second electromagnet, the winding directions of the coils of the first electromagnet and the second electromagnet are opposite, and both the first electromagnet and the second electromagnet are connected to the controller , the controller is electrically connected to the power supply. The invention can be used in individual products and mass production, avoiding repeated marking and alignment, improving production efficiency and ensuring the quality of workpieces.

The invention relates to a secondary slide block core pulling mechanism for a plastic mould. The secondary slide block core pulling mechanism comprises an upper compound plate and a lower compound plate, wherein the upper compound plate is connected to a fixed mould plate; a mould foot and a top plate are mounted on the lower compound plate; an ejector rod is mounted on the top plate; a moveable mould plate is mounted on the mould foot; and a mould cavity is formed between the fixed mould plate and the moveable mould plate; a molded plastic part is arranged in the mould cavity. The mechanism is characterized in that an I-shaped block is mounted on the lower compound plate; an external slide block is mounted on the I-shaped block; the external slide block is inserted into the inner wall of the molded plastic part; an internal slide block is arranged inside the external slide block; a compression spring and a pushing rod are mounted in the external slide block; the pushing rod is connected to the internal slide block; a mould-locking block is mounted in the fixed mould plate; a slope A and a slope B are respectively arranged at two sides of the mould-locking block; the slope A is in contact with the external slide block; the slope B is in contact with the moveable mould plate; and the external slide block is driven to pull outwards by virtue of a cylinder. A secondary slide block core-pulling mode is adopted in the scheme and the slide block is operated while the mould opening operation is performed, thereby shortening the core-pulling time, increasing the production efficiency, prolonging the service life of the mould and saving the cost.
