The application provides a soil slope planting base loosening and mulching construction device and relates to the technical field of slope repair. The device comprises a vehicle body, a forearm frame, a soil loosening mechanism, a first driving mechanism, a second driving mechanism, a soil covering groove and a seed throwing operation mechanism. The forearm frame is installed on the front side of the vehicle body, and side arms are arranged on the two sides of the forearm frame. A soil receiving groove is installed between the two side arms. A first spiral shaft is installed in the soil receiving groove. A transfer bin is installed on the outer side of the side arm. A transfer pipe is installed at the bottom of the transfer bin and extends above the soil covering groove. A second spiral shaft is installed in the transfer pipe. The soil loosening mechanism comprises a rotating ring and a strip-shaped plate. The rotating ring is rotatably installed on the inner side of the side arm. The strip-shaped plate is provided with a soil turning plate. A soil scraping plate is installed between the two side arms. The lower edge of the soil scraping plate is provided with a scraping groove. The soil loosening mechanism continuously completes the shallow soil loosening of the slope surface and simultaneously synchronously transports the in-situ soil generated by the soil loosening to the soil covering groove. The soil in the soil covering groove can also complete the post-seeding soil covering. The device realizes the integrated and continuous construction of soil loosening, seed throwing and soil covering.

The utility model provides an outdoor wind -resistant tent, including tent body, fills water ballast sac, fills water ballast sac setting at the bottom of tent body outside, and fills water ballast sac with tent between is provided with detachable connecting mechanism, fills water ballast sac includes sac body, is provided with fills water mouth on the sac body, and the seal cover is detachably connected on fills water mouth, one end of sac body is provided with pressure relief protection device, in the utility model, fills water mouth to fill water in water ballast sac, fills water ballast sac can significantly increase the overall weight of tent after filling water, and the pulling force of strong wind to tent is offset through the gravity effect of water ballast sac, avoids the tent to be blown away by strong wind when being idle, reduces the equipment damage and environmental safety risk. Fills water ballast sac distribution in the bottom of tent outside, can form the stable support surface of horizontal direction, forms the higher grip between tent and bottom surface through water ballast sac, and the tent is not prone to lateral transverse when the tent is subjected to crosswind effect.
