The invention discloses a quenching inductor for a conical pit of a brake disc and a matched application size determining method. The quenching inductor comprises a heating coil of the quenching inductor, a left square pipe, a right square pipe, a left round pipe and a right round pipe; the heating coil, the left square pipe, the right square pipe, the left round pipe and the right round pipe are hollow pipes; the water inlet end of the left square pipe is vertically welded with the water outlet end of the left round pipe, and the water outlet end of the left square pipe is horizontally welded with a water inlet pipe orifice of the heating coil; the water outlet end of the right square pipe is vertically welded with the water inlet end of the right round pipe, and the water inlet end of the right square pipe is horizontally welded with the water outlet pipe orifice of the heating coil; and one end of each of the left square pipe and the right square pipe communicates with the inside of the heating coil, and the other ends of the left square pipe and the right square pipe communicate with the insides of the left round pipe and the right round pipe respectively. The effective induction area is increased, and the problem that it is difficult to increase the induction heating efficiency is solved; the heating coil of the inductor is effectively coincided with the conical pit, and a gap is retained; and the heating efficiency and the depth of a hardened zone are guaranteed, and no fusing and ignition phenomena can be caused. The quenching inductor is reasonable in structure and reliable in application; and a matched application method is simple and feasible as well as easy to implement.

An automatic welding machine for internal U-shape welding comprises a longitudinal moving mechanism (1). A transverse moving mechanism (2) is mounted on the longitudinal moving mechanism (1). A vertical moving mechanism (3) is mounted on the transverse moving mechanism (2). A profiling welding mechanism (4) is mounted on the vertical moving mechanism (3). The profiling welding mechanism (4) comprises an induction mechanism, a connecting mechanism, and a machine head mechanism (51). The connecting mechanism is mounted on the induction mechanism. The machine head mechanism (51) is mounted on the connecting mechanism. The machine head mechanism (51) comprises a machine head fixing base (52). The machine head fixing base (52) is connected to the connecting mechanism. The automatic welding machine for internal U-shape welding can adjust the angle of a welding gun (80) at any time according to the arc-shaped welded joint direction of a U-shaped workpiece, thereby ensuring that the welding gun (80) is always perpendicular to a welded joint and ensuring the welding quality. In addition, when the welding gun rotates to a horizontal position, a machine head swing motor (49) can lock the machine head fixing base (52) in a horizontal state, thereby ensuring the quality of a perpendicular welded joint welded by the welding gun (80). The automatic welding machine for internal U-shape welding has a simple structure, convenient to process and manufacture, and is simple to use.

The invention belongs to the technical field of plant protection machinery and equipment, and relates to a mobile sprayer with a folding-arm spray device, comprising: a vertical spray mechanism, a horizontal spray mechanism, a support wheel, a buffer mechanism and an anti-collision mechanism. The vertical spraying mechanism and the horizontal spraying mechanism work together to meet the spraying requirements of the middle and lower parts of the canopy layer. The horizontal spraying mechanism can send the nozzle to the lower part of the canopy layer to improve the uniformity of the medicine inside the canopy and the back of the leaves; the support wheel can support the horizontal The spray mechanism reduces the operation jitter of the horizontal spray mechanism, and cooperates with the buffer mechanism to make the mobile sprayer have a certain ability to imitate the ground to meet the adaptability to different terrains; the anti-collision mechanism cooperates with the anti-collision sensor to ensure the safety of the operation to the greatest extent; In addition, the folding arm structure of the vertical spray mechanism and the horizontal spray mechanism can effectively improve the working space without affecting the inter-row passing and field transition capabilities.
