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 invention discloses a preparation method of copper-titanium alloy chopsticks, and relates to the technical field of non-ferrous metal alloys. Comprising the following steps: uniformly mixing raw materials to obtain mixed powder; the mixed powder is pressed into a consumable electrode bar, and a bar material is obtained; the bar is subjected to vacuum sintering at the temperature of 500-900 DEG C and then subjected to vacuum consumable electric arc melting, the melting current ranges from 1.5 KA to 3.0 KA, the melting voltage ranges from 18 V to 25 V, and a cast ingot is obtained; the cast ingot is forged, the final forging temperature is controlled to be not lower than 700 DEG C, and a round bar is obtained; the round bar is subjected to hot rolling treatment at the temperature of 830-900 DEG C, and a hot-rolled round bar is obtained; and carrying out solution treatment and aging treatment on the hot-rolled round rod, and then carrying out post-processing to obtain the finished copper-titanium alloy chopsticks. The copper-titanium alloy chopsticks have good mechanical properties, can reduce damage caused by collision in the use process of the chopsticks, and have obvious sterilization and bacteriostasis effects at the same time, so that the safe use performance of the chopsticks is improved.

The application discloses a TiAl alloy valve blank and a preparation method thereof, and belongs to the technical field of alloy material processing. The TiAl alloy valve blank preparation method comprises the following steps: preparing a TiAl alloy extrusion blank; heating the TiAl alloy extrusion blank and placing the TiAl alloy extrusion blank in a preheated extrusion die for extrusion to obtain an extruded part; and supplementing the temperature of the extruded part and die forging the extruded part to obtain a TiAl alloy valve blank. The application realizes the processing of the TiAl alloy under the condition of no cover, and the valve blank is prepared, and the problem that the TiAl alloy is difficult to form is effectively overcome.
