The sunflower harvesting and disc inserting machine comprises a walking vehicle, a plurality of harvesting and disc inserting mechanisms are arranged at the bottom of a vehicle frame of the walking vehicle side by side, and each harvesting and disc inserting mechanism comprises a harvesting assembly, a conveying mechanism and a disc pressing mechanism which are sequentially arranged from front to back in the advancing direction of the walking vehicle; the tail end of the harvesting assembly is arranged above the feeding end of the conveying mechanism, and the plate pressing mechanism is arranged behind the discharging end of the conveying mechanism. The sunflower harvesting and disc inserting machine has the advantages that the complex process of disc cutting and disc inserting is replaced by a machine instead of manual work, the labor intensity of workers is reduced, and it can be ensured that efficiency is not reduced or even improved even through long-time repeated operation.

The utility model discloses a sewage pump with an adjustable impeller gap, which comprises a pump body, a pump shell is arranged on one side of the pump body, a driving shaft is arranged in the pump body, one end of the driving shaft is movably connected with an impeller, the impeller is arranged in the pump shell, a liquid inlet is arranged on one side of the pump shell, and a liquid outlet is arranged on the other side of the pump shell. A liquid outlet is formed in the other side of the pump shell, and the distance between the impeller and the inner wall of the pump shell is adjusted through a distance adjusting assembly on the driving shaft. The utility model relates to the technical field of sewage pumps. According to the sewage pump with the adjustable impeller gap, through the arrangement of the distance adjusting assembly, the distance between the impeller and the pump shell is automatically adjusted, so that the gap between the impeller and the pump shell is reduced, the use efficiency of the pump is not reduced after the impeller is abraded, and the pump runs more stably.

The utility model belongs to life-saving equipment technical field, specifically disclose a kind of modularization pump spray propeller and lifesaving equipment.The utility model's modularization pump spray propeller, impeller of propeller operates in the uniform flow field in fairing, can effectively utilize inflow ram, so that it can better improve anti-cavitation performance at high speed, reach higher propelling efficiency, and not susceptible to water flow condition and sailing speed influence;The motor speed of propeller is changed by electronic speed regulator, to change the water velocity of fairing water outlet jet, and then the propelling force of propeller can be quickly changed;The motor speed of lifesaving equipment two sides propeller is changed by electronic speed regulator, to change the water velocity of two sides fairing water outlet jet and produce speed difference, that is, the quick steering of lifesaving equipment can be realized;Even if lifesaving equipment overturns, because the upper end and lower end of lifesaving equipment stern are all provided with propeller, the normal propelling use of lifesaving equipment is not affected.
