The invention discloses a vegetable seedling cultivation device, and belongs to the technical field of vegetable cultivation, the vegetable seedling cultivation device comprises a planting frame, an air injection component is arranged in the planting frame, the air injection component comprises air injection equipment fixedly connected to the back side of the lower end in the planting frame, and two first guide pipes are fixedly connected to the back side of the air injection equipment. On the premise that the net structure of the root system is not damaged, adhesion between the root system and the inner wall of the hole tray is relieved through the micro-vibration effect of airflow, compared with mechanical ejection, the integrity of the root system is improved, and the device is particularly suitable for melon and fruit seedlings with fragile root systems; the vegetable seedlings are prevented from being broken due to local stress concentration caused by mutual twisting of root systems when being pulled, so that the root systems are protected, meanwhile, in intensive seedling raising, the locking effect caused by root system coiling enables the breakage rate to be increased when a mechanical arm grabs the vegetable seedlings, and the transplanting survival rate is also prevented from being reduced due to the fact that roots of rhizomes are stabbed by traditional ejector pin type seedling jacking.

The application relates to a multifunctional airbag system for assisting a cross-medium vehicle to quickly cross media, which is suitable for a rotary-wing cross-medium vehicle and comprises an airbag buffer device, an airbag ballast device and a multi-airbag air volume unified control module. The airbag buffer device is arranged at the head of the cross-medium vehicle, the airbag ballast device is arranged at the middle section of the cross-medium vehicle, and the multi-airbag air volume unified control module is arranged at the tail of the cross-medium vehicle. The cross-medium vehicle is provided with three functions of underwater attitude adjustment, high-speed water entry buffering and rapid water exit assisting, the airbag ballast device replaces a traditional ballast water system, the inflation amount of the ballast airbag and the propeller power are controlled, and the functions of the cross-medium vehicle in underwater attitude adjustment, such as floating, diving and rotating, and the function of zero-energy consumption suspension in water can be realized.

This invention relates to the field of sludge solidification treatment equipment, and discloses a sludge solidification pretreatment device for river environmental management. The device includes a filter press assembly, a solidification assembly, and a mixing and feeding assembly. In use, the worm gear reciprocates forward / reverse, driving the fixed component and rotating ring to reciprocate. This causes two sliding rods to continuously move closer and further apart in a parallel state, adjusting the filter press plates to move closer and further apart. When the filter press plates move closer together, they squeeze the sludge between them to release water; when they move further apart, they squeeze the sludge between the filter press plates and the filter box to release water, dividing the sludge in the filter box into three parts and squeezing out water. As the rotating ring rotates, the scraper below it also rotates. The brush on the scraper tightly abuts against the filter box, and there is pressure between the brush and the filter box. Through the elastic deformation of the brush, it enters the through holes, promptly scraping away blockages inside the filter holes and outside the filter box. This invention has the advantages and effects of high dewatering efficiency, rapid and uniform mixing with the solidifying agent, and convenient unloading.

The utility model discloses a water-saving irrigation device for potato planting, which relates to the technical field of potato planting, and comprises a supporting disc, a supporting ring and an adjusting frame, and by arranging an adjusting mechanism and a rotating part, the height of potatoes in different growth periods can be adjusted when the potatoes are irrigated. By arranging a fixing mechanism, a transmission part, a connecting part and a sliding part, a fixing motor is started to drive a fixing shaft detachably and fixedly connected with the output end of the fixing motor to rotate, so that a fixing disc fixedly connected with the fixing shaft rotates, and then a transmission plate rotationally connected with a first transmission shaft is driven to rotate; by arranging a second transmission shaft, a sliding block fixedly connected with the second transmission shaft slides in a sliding groove in a connecting disc, so that arc-shaped plates fixedly connected with the sliding block are driven to get close to each other, potatoes are clamped, by arranging an adjusting mechanism and a fixing mechanism, the potatoes are irrigated more quickly and conveniently, water loss for irrigation is avoided, and the potato planting efficiency is improved. And water resources are wasted.
