Description

Technical Field

[0001] The utility model belongs to the technical field of construction machinery and equipment for concrete pouring, and particularly relates to a discharging device for a concrete hopper. Background Technique

[0002] With the rapid development of the country's infrastructure construction, stricter requirements have been put forward for the construction quality and production safety, especially for the quality control requirements during the construction process, which increases the costs of construction enterprises. Construction enterprises also put forward refined management, aiming to save the waste of raw materials on the premise of ensuring quality during the construction process.

[0003] Whether in modern construction technologies such as industrial and civil construction projects, transportation projects, water conservancy projects, and prefabricated buildings, concrete, as the main building material, has been closely related and inseparable from modernization construction, accounting for a large proportion in modern engineering construction. Therefore, concrete pouring is particularly important. Although modern pouring machinery such as truck-mounted concrete pumps and stationary concrete pumps are already available, the mechanical equipment is greatly affected by the site, and the preparatory work volume is large during the formal construction. Therefore, in the case of small-volume concrete pouring and relatively narrow sites and other unsatisfactory site conditions, it is difficult for the mechanical equipment to play its role; therefore, in this case, hoppers are mostly used for pouring.

[0004] The existing construction method is that when pouring concrete, a hopper is lifted by a crane and hoisted to the pouring position after loading. At the same time, two workers are required to cooperate to open the hopper door under the hopper for pouring. In narrow places, due to site restrictions, it is very difficult for the workers who cooperate to open the bin to stand firm at the pouring site, with too high safety risks, and the construction efficiency is extremely slow, seriously affecting the construction progress and increasing labor costs.

[0005] Based on the above problems, the utility model proposes a discharging device for a concrete hopper. Content of the Utility Model
