The application provides a method and device for protecting a stretch limit position, a vehicle and a storage medium. The method comprises: obtaining a vehicle speed value when it is determined that the vehicle enters a preset stretch limit position protection mode; increasing the current of a shock absorber in the vehicle according to the vehicle speed value; and increasing the damping force generated by the shock absorber according to the increased current, so as to protect the stretch limit position of the shock absorber. The above method obtains the vehicle speed of the shock absorber, and increases the current of the shock absorber at different speeds according to the vehicle speed of the shock absorber, so as to increase the damping force of the shock absorber at different speeds. When facing a larger impact, the problem of abnormal sound of the stretch limit position of the shock absorber can be better avoided by increasing the damping of the shock absorber, and the hard contact of the buffer device in the shock absorber is reduced, so as to reduce the influence on the durability of the shock absorber.

This invention relates to the field of agricultural product processing equipment technology, and more particularly to a washing and sorting device for processing jujubes, comprising a rinsing tank, an ultrasonic cleaning box, and an air-drying sorting box arranged sequentially. In the air-drying sorting box, during rotation, a scraper sprays air through vents, simultaneously creating a forced airflow through a negative pressure exhaust port at the top, accelerating the evaporation of moisture from the jujube surface. The sorting holes on the multi-layer sorting disc decrease in size from top to bottom, and the jujubes tumble layer by layer under the push of the scraper, achieving precise multi-stage sieving. The scraper has a hollow cavity with vents, creating an air cushion effect during the jujube pushing process, reducing hard contact between the scraper and the jujubes and minimizing frictional damage. Simultaneously, the rotation of the scraper, combined with the air-drying action, keeps the jujube surface dry, further reducing surface wear during the grading process.
