The invention discloses a corn grain screening device and method and relates to the field of corn screening. The corn grain screening device comprises a machine shell. An arc rail is arranged on the front side of the inner cavity of the machine shell. The inner wall of the arc rail is connected with a slider in a sliding manner. One side of the slider extends to the back side of the arc rail and is provided with a connection rod. One end of the connection rod is provided with a screen net. One side of the screen net is fixedly provided with a permanent magnet. An electromagnet is fixedly installed on one side of the inner wall of the machine shell. A servo motor is fixedly installed on the top of the machine shell. One end of a rotating shaft of the servo motor is in transmission connection with a main shaft. One end of the main shaft extends into the machine shell and is fixedly provided with a rotating mechanism. A springback mechanism is fixedly installed on the other side of the inner wall of the machine shell. The corn grain screening device can exert one gravitational acceleration on the screen net so as to increase the gravitational potential energy during screen net shaking, so that the vibration amplitude of the screen net can be improved, then the corn grain is screened more thoroughly, and the uniformity of corn grain screening is guaranteed.

The invention provides a noise reduction method for a GFD (D) series transformer fan, which includes a fan casing, a spring fixedly installed inside the fixed seat, a support plate fixedly connected to the top of the spring, a gravity ball placed on the top of the support plate, and a fixed seat There is a rolling groove corresponding to the gravity ball inside, the bottom of the liquid storage tank is fixedly connected with a nozzle, and the left side of the liquid storage tank is provided with a button corresponding to the nozzle. By setting the spring and the support plate, the gravity ball will shake up and down in the rising groove with the vibration of the fan casing, and the spring will push the gravity ball into the acceleration groove, and then the gravity ball will move along the acceleration groove, the matching groove and the acceleration groove under the action of gravity. The fallback groove rolls, pushes the baffle and falls back to the support plate. When the gravity ball falls in the fallback groove, it will toggle the button to open the nozzle and spray lubricating fluid to the bearing for lubrication, which effectively solves the problem of The poor lubrication of the bearings leads to the problem of increased noise of the fan.

The invention discloses a multilevel rocking type baby stroller driven by a Geneva drive with double driven wheels. The multilevel rocking type baby stroller comprises a bottom plate, a baby chamber arranged at the upper part of the bottom plate and a pair of front wheels and a pair of rear wheels mounted at the four corners of the lower surface of the bottom plate, wherein upright beams fixedly connected to the bottom plate are respectively arranged at the front and rear side surfaces of the baby chamber; and fixing blocks are fixedly connected to the top ends of the upright beams. The reciprocating swinging of the baby chamber increases the fun of the baby stroller so as to avoid crying of a baby, to avoid the need for people to hold and rock the baby and to save manual labor. Springs are arranged to allow the rocking of the baby chamber to be not too violent, so that the experience of the baby can be comfort. The baby chamber can be rocked by manually pushing the baby stroller, so that the use is convenient. Fastening screws are removed so that a rotating shaft does not drive a drive wheel anymore; tightening screws are tightened so that the baby stroller is not rocked anymore and can be used as an ordinary baby stroller; and the operation is simple.

A bit distribution method of groups of video pictures based on H.264 is applied to a video picture encoder which controls the code rate of video stream encoded in real time. The method comprises the following steps: A. the approximation of the quantization parameter mean QPm of a first frame in the video stream GOP is estimated and set as QPi; B. the frame I in the video stream GOP is encoded; C.the present output code rate is calculated; D. according to the code rate calculated in the step C, the QP value of the subsequent frame B or P is adjusted; E. the frame B or P is encoded; F. when the video stream is not over, the step C is executed once again; G. the video stream is over. According to the target code rate and the complexity of the picture contents, the bit distribution method reasonably determines a quantization parameter of the first frame in the groups of video pictures, thus carrying out the bit distribution on the groups of pictures; under the circumstance of one-time encoding, the optimization of the rate distortion can be well realized and the quality of the pictures is relatively stable.

The invention discloses a sanitary napkin with deodorizing and antibacterial functions and a manufacturing method thereof, and relates to the technical field of sanitary napkin manufacturing. The sanitary napkin with deodorizing and antibacterial functions and a manufacturing method thereof include an external control mechanism, wherein the external control mechanism is internally provided with a casing, the inner bottom of the casing is fixedly connected with a rotary extrusion mechanism, and the external control mechanism is connected with the external control mechanism. The rotating extrusion mechanism is fixedly connected, a first elastic rod is arranged inside the shaking and hitting mechanism, the top of the first elastic rod is fixedly connected with the shaking and hitting mechanism, and the rotating extrusion mechanism is fixedly connected with the shaking and hitting mechanism. The sanitary napkin with deodorizing and antibacterial functions and the manufacturing method thereof are arranged in a spiral through the screw rod, and the sticking thorn at the top of the screw rod will be stuck into the paper, and then stuck into the paper under the rotation of the screw rod, The setting of the screw rod can speed up the pulling down of the paper, so that the paper is soaked in water, and the speed of water soaking is ensured.

The invention discloses a water flow curtain wall type dust-proof and cooling transformer, which belongs to the technical field of transformers. The device drives an inflatable balloon through a rubber seal to contact with an aqueous solution by pushing a fixed handle, and then starts a circulating water pump to make the aqueous solution circulate internally. Flow, when the transformer generates a lot of heat due to long-term operation, the thermal fluid in the fixed sleeve absorbs heat and evaporates at one end of the transformer, turning into a gas, and reaches the end of the expansion balloon under the action of the pressure difference to liquefy and release heat, and then condenses and becomes The formed liquid flows back to one end of the transformer, and back and forth in this way, the heat dissipation effect is enhanced, and when the thermal fluid transfers heat to the end of the expansion balloon, the expansion balloon expands due to heat absorption, causing the diaphragm on its surface to separate, and the continuous contact with the aqueous solution The heat generated inside the transformer continues to flush and dissipate heat, resulting in contact with the potassium nitrate powder at this time, thereby continuously dissipating heat from the transformer.
