Description

Technical Field

[0001] The utility model belongs to the technical field of silos, and in particular relates to a cover opening device and a feeding assembled silo comprising the cover opening device. Background Art

[0002] The silo has a feed port, which is generally hinged with a silo cover. When the silo cover is opened for feeding, the silo cover is still connected to the silo body, affecting the feeding. The silo has a certain height due to its structure. Manual opening requires the use of a ladder outside the silo to reach the top of the silo. The maximum height can reach nine meters, which has a certain risk of climbing. The breeding farm usually uses the silo group method for feeding the prefabricated steel silo. There are many silos, and frequent climbing causes fatigue to personnel, resulting in increased risk of climbing. In the daily use of the conventional manual opening method, three problems will arise: 1. When feeding, the feed contacts the silo cover, which will corrode the silo cover. In addition, the high corrosion environment of the breeding farm causes the silo cover to rust; 2. The high height of the silo leads to the risk of manual climbing; 3. The frequent feeding of the silo group leads to fatigue of manual climbing. In addition, the feed is highly corrosive, and the breeding farm itself has a harsh environment, which aggravates the corrosion of steel. The strength of the rusted steel is damaged and cannot be used. Therefore, it is urgent to solve the problems of harsh environment and difficulty in opening the cover that have long plagued the use of prefabricated steel silos for feeding during project operation.
