The invention relates to a comb-cutting type sunflower harvesting method and header. The Comb-cutting type sunflower harvesting method and header header comprises a rack, a comb-supporting type standing grain pulling mechanism, a translation mechanism, a lifting mechanism, a cutting mechanism and a conveying mechanism. The cutting mechanism is used for cutting off stalks of sunflowers. The comb-supporting type standing grain pulling mechanism is used for supporting sunflower discs of the sunflowers in good time and throwing plants to the conveying mechanism after the lower ends of the plants are cut off. The translation mechanism and the lifting mechanism are used for driving the comb-supporting type standing grain pulling mechanism to move in the horizontal direction and the vertical direction respectively. The functions of a divider are integrated by the comb-supporting type standing grain pulling mechanism, hitting of a standing grain wheel to the sunflower discs and damage caused by grain falling are greatly reduced, the position of the comb-supporting type standing grain pulling mechanism can be independently adjusted up and down or front and back, comb-supporting and cuttingactions are timely, effectively and stably completed in cooperation with the cutting mechanism, and therefore the header adapts to the differentiation of sunflower plant heights and sunflower disc distribution height ranges under the condition of different plots or varieties.

The invention relates to a surgical method for two-step excision of a patient side liver by a liver winding belt method under a complete laparoscope, which comprises the following steps that: (1) a patient undergoes complete laparoscopic surgery in a general anesthesia state, the liver winding belt method is used for ligating a portal vein branch of the to-be-excided patient side liver, meanwhile, a liver winding belt is used for tightening the connecting portion between the left liver and the right liver to block traffic blood flow between the to-be-excided patient side liver and the to-be-reserved half side liver, after an abdominal cavity drainage tube is reserved at the portal of the liver, the abdomen is closed, and the first operation is completed; (2) after the first operation, the patient gradually recovers diet and recures for 6-15 days, so that the volume of theto-be-reserved half side liveris increased to the expected residual liver volume which is 30-40% or above of the standard liver volume; and (3) after the volume of the to-be-reserved half side liverof the patient is increased to the expected residual liver volume, a second operation is performed, a complete laparoscopic operation under general anesthesia is performed to excide the half-side liver of the patient, and the patient recures until complete rehabilitation. The invention further discloses a pressure-adjustable liver tightening device special for the surgical method.

The invention relates to the field of housing construction equipment, in particular to an earthquake-resistant structure of civil engineering and a method thereof. The earthquake-resistant structure comprises a damping cylinder; an upper connecting plate is integrated on the upper portion of the damping cylinder; a lower connecting plate is integrated on the lower portion of the damping cylinder; steel plates and rubber plates are arranged in staggered modes in the damping cylinder; a lead core rod is arranged in the central part of the damping cylinder through a through hole in a penetrating mode; and the earthquake-resistant structure of civil engineering is arranged in a housing earthquake-resistant layer or a nonbearing wall. According to the earthquake-resistant structure of civil engineering, the effects of bearing and fixing on a building are achieved, the effects of earthquake isolation and damping on an earthquake can be further achieved, and the safety degree of the housing building is improved.

The invention provides a striking pad. A pad part (11) and a connection part (12) of the striking pad (10) are made of soft materials such as rubber materials with elasticity. A peripheral part (11b) of the connection pad part (11) and a support part (13) are connected by the connection part (12), so that the pad part (11) is supported on the support part (13). The connection part (12) forms a thin wall which forms a bending shape and is bent to the inner diameter direction of the support part (13) under a non-striking state. When a striking face of the pad part (11) is struck, the connection part (12) elastically deforms mainly through compression or bending in elongation, compression and bending. The connection part (12) allows at least the peripheral part (11b) of the pad part (11) to displace towards the striking direction.

The invention discloses a shock-resistance flow meter and belongs to the field of fluid metering. The shock-resistance flow meter comprises a tube body; two ends of the tube body are provided with a water inlet and a water outlet respectively; a protruding opening is formed at the top of the middle of the tube body; a guide plate is disposed inside the tube body; the top end of the guide plate isfixedly connected with a metering box; the middle of the metering box is provided with a flow guiding mechanism; and the bottom of the metering box is provided with a buffering mechanism. According tothe shock-resistance flow meter of the invention, a fluid is guided to the flow guiding mechanism through the guide plate, so that the fluid decelerates and flows into the metering box; hydraulic pressure in the metering box is more stable compared with hydraulic pressure in the tube body; when the hydraulic pressure fluctuates, the buffering mechanism adjusts the pressure of the fluid, a pistonslides down, so that the space of the metering box can be expanded, and therefore, a buffering and pressure reduction effect is achieved; when the pressure drops back, a spring pushes the piston up, so that a pressure stabilizing effect is achieved, and therefore, the protection of a measuring assembly is benefitted, and measurement accuracy is improved; a filter screen filters the fluid before the fluid is metered, so that impurities can be intercepted, and therefore, impact on the probe of the measuring assembly can be decreased, and the wear of the measuring assembly can be reduced.
