The application discloses a dry land corn seeding and film covering integrated machine and relates to the technical field of agricultural machinery. The machine comprises a rack, a processing mechanism arranged in the rack, a ploughing device, a ridger and a film covering frame fixedly installed on the inner wall of the rack, a seeding machine fixedly installed on the outer surface of the rack, a controller fixedly installed on the outer surface of the rack, a film discharging assembly arranged in the rack and a soil covering assembly arranged in the rack. The dry land corn seeding and film covering integrated machine is provided with a film discharging mechanism. When the device encounters hard soil blocks, instantaneous deceleration or temporary stop, the unwinding damping instantaneously increases, the roller shaft is difficult to rotate, the film is prevented from being continuously excessively pulled out, the film is prevented from being relaxed or accumulated due to the stop of the machine, the friction on the roller shaft is reduced when the device passes through the hard soil blocks or accelerates forward again, the film is allowed to be quickly pulled out, and the film is prevented from being torn due to excessive tension.

The utility model relates to a butt-joint interlocking structure for a mother-son bed frame, which comprises a mother bed structure and a son bed structure, and one side of the lower part of the mother bed structure is provided with an inserting gap; a bayonet socket is arranged at the lower part of the sub-bed structure, and the bayonet socket of the sub-bed structure can be inserted into the insertion notch; at least two self-locking structures are arranged side by side on the side wall, butted with the bayonet socket, of the splicing gap, each self-locking structure comprises a butting rotating shaft, a hook arm and a hooking roller, the butting rotating shaft is rotatably mounted on the splicing gap and is fixedly butted with one end of the hook arm, and the hooking roller is fixedly butted with the other end of the hook arm. The other end of the hook arm is rotatably provided with a hook connection rolling wheel, the bayonet socket is provided with a hook foot structure which is in butt joint with the hook connection rolling wheel, and a torsion spring structure is arranged between the butt joint rotating shaft and the hook arm. The child bed has the advantages of being high in structural strength, good in locking effect, capable of reducing potential safety hazards caused by accidental disengagement, convenient to rapidly disengage from and be inserted into the child bed and the like.

The invention relates to the technical field of fire-fighting reels, and discloses an automatic winding fire-fighting reel which comprises a base support and a center pipe. A reel pipe is wound on the reel; the control mechanism is used for controlling winding of the reel pipe and drainage during winding; one end of the central pipe is connected with a valve pipe, and a connector is arranged on the valve pipe. According to the automatic winding fire-fighting reel, automatic electric winding of the reel can be achieved through the arranged servo motor, meanwhile, the servo motor is disconnected with the reel, the overall water pipe pulling-out resistance is reduced, the water pipe is pulled out more smoothly, and therefore the winding efficiency of the water pipe is improved. A circulating inflating structure is formed by utilizing the rotating power of the water pipe in the winding process, the wound water pipe is continuously inflated, then accumulated water in the water pipe is subjected to air pressure type inflating and self-discharging, it is guaranteed that the accumulated water in the water pipe can be effectively discharged, therefore, the protection performance of the water pipe is improved, and the material hardening condition caused by long-time water accumulation is avoided.

This invention discloses a flipping device and method for the housing of a new energy motor, belonging to the field of motor housing flipping technology. The flipping device for the housing of a new energy motor includes a driving unit on the flipping fan, and a pressure plate slidably connected to one side of the flipping fan. The pressure plate is rotatably connected to the driving unit and tilted towards the junction box of the rear end cover. The pressure plate is rotatably connected to a sliding frame, and a spring makes the pressure plate initially tilted towards the junction box. During the pressing process, the lowermost end of the pressure plate first contacts the flange, and gradually rotates until it is parallel to the flange as the pressing continues. If the rear end cover is misaligned, the arc-shaped side of the pressure plate will first abut against the side wall of the junction box, pushing the rear end cover to rotate and correct until the arc-shaped side is completely in contact with the junction box. The pressing action of the pressure plate alone can simultaneously complete the pressing and positioning correction, avoiding the risk of accidentally pressing the junction box and improving the workpiece positioning accuracy.
