Provided is a homogenizing mixer including: a container having an internal space so that materials whose properties differ are contained therein; a fixed frame that is disposed so as to be fixed at the bottom of the container, and communicates from the inside of the container; an agitating unit that is disposed in the fixed frame, so as to be lifted up and down by medium of an lifting unit, and that agitates the materials contained in the container; a driving unit that is disposed on the bottom of the agitating unit for transferring a rotational driving force for the agitating unit; and a discharging unit that is coupled to the agitating unit and discharging a homogenized material to the outside of the mixer.

The invention discloses a photovoltaic support for a color steel tile. The photovoltaic support comprises a bearing plate, a lifting supporting column, a flat plate and a supporting column, wherein the bearing plate is arranged on a color steel tile body, the bottom end of the lifting supporting column and the bottom end of the supporting column are both connected with the bearing plate, and a guiding sliding block is arranged at the lower end of the flat plate and hinged to the top end of the lifting supporting column; the high end of the flat plate is hinged to the top of the supporting column; grooves are formed in the bottom of the bearing plate; the corrugations of the color steel tile body are embedded into the grooves; a tightening mechanism is arranged at the bottom of the bearingplate; and after installation, the tight supporting end of the tightening mechanism abuts against corrugations of the color steel tile body. According to the structure, the bearing plate can be connected with the color steel tile body, and the bearing plate is embedded into the corrugated groove, so that convenient installation is realized; the tight supporting end of the tightening mechanism is propped against the corrugations of the color steel tile body, so that the bearing plate is prevented from sliding relative to the color steel tile body; the flat plate is hinged to the supporting columns and the lifting supporting column, and the guiding sliding block is arranged in the flat plate, so that the height of the lifting supporting column is changed; and meanwhile, by changing the position of the guiding sliding block, the angle of the flat plate is changed, and benefits are increased.

The invention discloses a rail switch lifting device and relates to the technical field of rolling equipment. The rail switch lifting device comprises a support, a cylinder and a connector. A clamp at the upper end of the connector is in clearance fit with a clamp groove formed in the lower surface of a steel rail and can transversely swing in the same. The lower end of the connector is connected with a guide pillar of the cylinder, and the lower end of the cylinder is hinged to the support. Lifting of the guide pillar of the cylinder drives lifting of a rail switch. Some deflection of the rail switch relative to the support can be guaranteed since the lower end of the cylinder is hinged to the support and the clamp at the upper end of the connector is in clearance fit with the clamp groove in the lower surface of the steel rail. Threaded connection of the connector and the upper end of the cylinder facilitates mounting. Former structures of oscillating cylinders, gears, racks and guide arms are substituted by the rail switch lifting device, and lifting of the rail switch is simplified on the premise of meeting lifting requirements. The rail switch lifting device has the advantages of simple structure, convenience in operation and maintenance, low cost and practicality.

The invention provides a rotating and lifting mechanism of a pin clamp fixing ring. The rotating and lifting mechanism comprises a rotating and lifting plate, a base, a plurality of limiting wheels, aplurality of radial locators, an inclined-wedge-shaped rotating and lifting mechanism and a rotating-lifting driving device. The base with a through hole sleeves the rotating and lifting plate. The limiting wheels contact with the periphery of the through hole. The radial locaters are connected with the lower end of the rotating and lifting plate. The inclined-wedge-shaped rotating and lifting mechanism is arranged between the base and the outer periphery of the rotating and lifting plate. The radial locaters are distributed along the circumference of the rotating and lifting plate. The rotating and lifting mechanism has the advantages that the rotating and lifting plate is driven to rotate and rise through the rotating-lifting driving device, occupied space of the lifting structure is small, the rotating and lifting plate rotates and rises synchronously, and pin clamp replacement efficiency is high; through the limiting wheels contacting with the periphery of the through hole and theradial locaters connected with the lower end of the rotating and lifting plate, centring accuracy during rotating of the rotating and lifting plate is high, and axial lifting of the rotating and lifting plate is smooth.

The invention discloses an automatic vending machine. The automatic vending machine comprises a box body, goods shelves, separating parts, first synchronizing wheels, second synchronizing wheels, push plates, first gears, a goods receiving groove, a lifting mechanism, a movement assembly and a driving structure. The first gears are arranged at the ends of the first separating parts, and the first gears and the first synchronizing wheels are in transmission connection. The movement assembly and the driving structure are in transmission connection, the movement assembly is used for driving the driving structure to move from one side of each goods shelf to the other side of the goods shelf along the goods receiving groove, and second gears and the first gears are meshed in the process that goods are pushed by the push plates from goods channels to the goods receiving groove. According to the automatic vending machine, the operation that motors are correspondingly arranged on the goods channels is not required, when the driving structure on the goods receiving groove is moved to the end of each goods channel, the driving structure on the goods receiving groove can drive the corresponding first gear to work, the purpose that the goods are pushed out of the goods channel can be achieved, and therefore the number of the motors can be greatly reduced, and the cost of the automatic vending machine can be reduced.
