Abstract: The disclosure relates to an auger assembly and a snow thrower including a supporting shaft; a snow throwing paddle, a left and right snow scraper assembly. The snow throwing paddle in a middle of the supporting shaft rotates synchronously with the supporting shaft. The left and right snow scraper assemblies are symmetrical to each other with respect to a particular plane that is perpendicular to an axis of the supporting shaft. The left snow scraper assembly includes a snow scraper helically spiraled around the supporting shaft along an axial direction of the supporting shaft. The snow scraper is spliced by at least two-section split helical blades each helical blade provided with a connecting part at an end away from the snow throwing paddle. The connecting part is connected with the supporting shaft. One of the helical blades closest to the snow throwing paddle is connected with the snow throwing paddle.

Abstract: The disclosure provides a snow thrower and a steering method thereof. The snow thrower includes a chassis, a wheel assembly, a working assembly, a power assembly and a battery assembly. The wheel assembly is connected with the chassis and includes wheels arranged at both sides of the chassis. The working assembly is connected with the chassis and includes an auger assembly and an impeller assembly. The auger assembly includes an auger and a auger housing at least partially accommodating the auger. The impeller assembly includes an impeller and an impeller housing at least partially accommodating the impeller. The power assembly includes a motor and is connected with the working assembly to drive the working assembly to work. The battery assembly is connected with the power assembly and the wheel assembly, and the battery assembly includes at least one battery.

Abstract: The disclosure provides a power head and an outdoor power equipment using the same. The power head includes a housing assembly, a motor assembly and a battery pack assembly. The housing assembly includes a first housing and a second housing. The first housing and the second housing defines a housing space. The motor assembly is arranged in the housing space. The motor assembly includes a motor. One end of an output shaft of the motor extends to outside of the housing assembly. The battery pack assembly is arranged inside the housing space. The battery pack assembly supplies power for the motor assembly.

Abstract: Polycyclic compounds that are aromatic or partially aromatic, and are substituted with one or more alkyl groups having an amino group and a carboxylic acid group, and includes carbon quantum dots (CQDs) that contain these compounds. The compounds and CQDs have a selective affinity for cells that express LAT1 and for tumor cells, and can internalize within such cells. The compounds and CQDs are useful for imaging of such cells and for delivering cargo compounds to and into cells that express LAT1 and tumor cells. Methods for making and using these compounds and CQDs for bioimaging and targeting certain tissues, including tumors, are disclosed.

Abstract: A snow thrower is provided and includes: a snow removal system and a power system configured to drive the snow removal system to work. The power system includes a first motor. The snow removal system includes a transmission shaft, an auger assembly in transmission connection with the transmission shaft, and a snow throwing impeller mounted to the transmission shaft. An output shaft of the first motor is connected with the transmission shaft directly, so that when the first motor rotates, power is transmitted to the transmission shaft through the output shaft, so as to drive the auger assembly to rotate.

Abstract: The present invention discloses an automatic adjustment device for a front suspension of a driverless formula racing car, comprising: a vertical column, an upper fork arm, a lower fork arm, a strength adjuster, a push rod, a rocking block and a shock absorber. By arranging the strength adjuster between the upper fork arm and the lower fork arm, and by adjusting the degree of tightness between the upper fork arm and the lower fork arm, the present invention can automatically adjust the tensile and support strength of the strength adjuster according to different car conditions and road conditions in which the racing car runs, to guarantee the structure stability of the front suspension in the running process, and prevent the front suspension from being loosening or fracturing, thereby having good adaptability and stability to structural deformation.
