According to the spraying dust removal device capable of leveling the land and used for the construction site, a first leveling mechanism and a second leveling mechanism are arranged, the ground is pressed through a pressing roller ring at the tail of a vehicle plate, vibration pressing boxes compact the two sides of the vehicle plate under the action of a vibration motor, and due to the fact that the two ends of the pressing roller ring and the two vibration pressing boxes are staggered in the range, the two sides of the vehicle plate are tightly pressed; therefore, the road surface can be fully leveled, dust in the air is mixed with water and falls on the ground under the action of the fog gun machine in the reciprocating motion process of the tricycle main body, the purpose of road leveling is achieved through the pressing and compacting action of the pressing roller ring and the vibration box, and the problems that an existing fog gun machine can only carry out dust falling treatment on raised dust, and the road surface cannot be leveled easily are effectively solved. The problems that the road cannot be leveled, dust on the road can be raised repeatedly when the engineering vehicle runs, and dust raising cannot be restrained are solved.

The invention relates to a sealing assembly and a rolling bearing. The sealing assembly is annular as a whole and comprises a framework with a radial inner end; the sealing body is attached to the framework, a dynamic sealing lip inclining towards the first axial side is arranged at the position, at the radial inner end of the framework, of the sealing body and used for abutting against a bearing inner ring in a dynamic sealing mode, and a plurality of grooves spaced in the circumferential direction are formed in the position, at the second axial side, of the lip edge of the dynamic sealing lip. The groove divides the lip edge of the dynamic sealing lip into a thin lip edge and a thick lip edge in the circumferential direction. The groove is formed in the lip edge of the dynamic sealing lip, so that when the lip edge of the dynamic sealing lip abuts against the bearing inner ring in a dynamic sealing mode, the lip edge of the dynamic sealing lip is easier to stretch in the circumferential direction, the banding force on the bearing inner ring is reduced, the radial force on the bearing inner ring is reduced, abrasion between the dynamic sealing lip and the bearing inner ring is reduced, and the service life of the dynamic sealing lip is prolonged. The dynamic sealing lip is prevented from being separated from the bearing inner ring due to abrasion, the service life of the sealing assembly is prolonged, and the sealing assembly can conduct electricity for a long time.

The utility model relates to battery technical field discloses the electric core cover plate subassembly, electric core and battery package, wherein the electric core cover plate subassembly, include: cover plate body, pole body and pole bottom plate, cover plate body is seted up and is installed the hole, pole body is inserted in the installed hole and extends to the first surface of cover plate body at least, the cross section of pole body is track and field runway shape, the size of pole body along cover plate body length direction is L1, the size of pole body along cover plate body width direction is W1, satisfy L1>W1, pole bottom plate is connected with one end of pole body and is located in the second surface opposite with the first surface of cover plate body, the size of pole bottom plate along cover plate body width direction is W2, satisfy 0.25<=W1 / W2<=0.5. The utility model discloses the pole body of track and field runway shape can ensure the overcurrent capacity, and through the processing size of pole bottom plate and pole body, can ensure the processing quality of pole body.
