The invention discloses an overturning hopper. The overturning hopper comprises a hopper body, a hopper revolving support and an overturning mechanism, wherein the overturning mechanism comprises a link and a crank, one end of the link is hinged onto the hopper body, the other end of the link is hinged with the crank, and the other end of the crank is hinged onto a crank revolving support through a crank rotary shaft; and the receiving point and the unloading point of the hopper are both arranged at or close to the dead point of the overturning mechanism through optimizing the starting point and the ending point of the crank, so that the impacted force working condition of speed reducer equipment is optimized during the loading and the unloading of the overturning hopper. According to the mechanism, the centre-of-gravity position of the hopper body and the centre-of-gravity position of the hopper after the loading are further optimized, so that the centre of gravity of the hopper body is located between the revolving hinge point of the hopper and the supporting hinge point of the link and close to the revolving hinge point of the hopper; and requirements on the output torque of a speed reducer are greatly lowered by virtue of the force amplification effect of the link, so that the weight of the speed reducer equipment and the power of a tilting motor are greatly reduced, and the motor power and the energy consumption of the system are saved.

The invention provides a robot arc welding method suitable for splicing of horn-shaped structures. The method comprises the following steps that every two horn-shaped plates to be assembled are spliced, and protrusion parts are arranged on splicing heads and are used for filling materials into welding seams in a splicing welding mode; the horn-shaped plates to be assembled are assembled and fixed; a welding space lattice is set; welding gun paths are determined according to the welding space lattice and are stored in an arc welding robot. The robot arc welding method improves welding seam forming evenness and welding quality stability. Compared with manual argon tungsten-arc welding, pulse welding of the arc welding robot forms fish scale-shaped welding seams which are even and beautiful. Acquired welding seams are uniform in weld penetration under connector size characteristic control. Compared with a horn body formed by furnace brazing in a furnace, welding seams formed by welding according to the robot arc welding method do not have residual brazing fluxes, follow-up machining processes are reduced, and salt mist resisting performance, hot and humid resisting performance and mildew preventing performance of a connector are improved.

A method for multiplexing video input and component input interfaces in a television receiver, the video signal includes one video signal and two left and right audio signals, the component signal includes one luminance signal and two color difference signals; the same group of RCA signal terminals is used , through the signal channel switching circuit, the common use of video signal and component signal input terminals is realized. On the premise of ensuring the number of signal channels, the number of signal input terminals is greatly reduced, and the structural requirements of the flat panel TV are met.

A hydraulic output connection structure applied to tractors and used with agricultural implements comprises a hydraulic output bottom plate, a bolt, a hydraulic output cover plate, an O-shaped seal ring I, two O-shaped seal rings II, a hydraulic output valve connecting plate, hydraulic output oil pipes, O-shaped seal rings III, and hydraulic output pipe joints. The hydraulic output valve connecting plate is mounted on the hydraulic output bottom plate. The O-shaped seal rings II are mounted at the end of the hydraulic output valve connecting plate which is fastened through the bolt; one end of one hydraulic pipe joint and one end of the other hydraulic pipe joint are tightened in two threaded holes of the hydraulic output connecting plate; the O-shaped seal rings III are set at the other ends of the hydraulic pipe joints; and the hydraulic pipe joints are connected with two hydraulic output oil pipes. The hydraulic output connection structure has the advantages that the structure need of the tractors used with various types of agricultural implements for multi-unit hydraulic output is met, the hydraulic output connection structure is convenient to mount and demount, simple in structure, low in cost and reliable in performance, and the application range of tractors, required by users, is wider.
