Rotary type opening and closing sealing cap

Abstract

The invention relates to a rotary type opening and closing sealing cap. The rotary type opening and closing sealing cap mainly comprises a barrel body. Two connecting poles are arranged at the front end of the upper portion of the barrel body. Two semicircular barrel caps capable of being spliced into a whole circle are correspondingly connected with the lower portions of the two connecting poles in a one-to-one mode. A main driving gear is connected with the upper portion of one connecting pole of the two connecting poles, and an auxiliary driving gear is connected with the upper portion of the other connecting pole of the two connecting poles. The main driving gear is engaged with the auxiliary driving gear. The main driving gear is engaged with a big gear ring. A circular ring frame is arranged in the direction of an inner circular ring of the big gear ring. Circular arc grooves are evenly formed in the inner circular arc end of the circular ring frame. A fixing base is installed at any end of the big gear ring. A hydraulic cylinder is installed on the fixing base. A clamping plate base of which the position and the shape are both matched with those of the circular arc grooves is connected with the hydraulic cylinder. According to the rotary type opening and closing sealing cap, the opening and closing degree of the two semicircular barrel caps is controlled accurately and effectively by controlling the rotating angle of the big gear ring and the matching effect of the clamping plate base and the circular arc grooves, and thus the effect that the dumping amount of cement is conveniently controlled by operators is achieved.

Description

technical field [0001] The invention relates to the field of building cement containers, in particular to a rotary opening and closing cover. Background technique [0002] Generally speaking, when construction cement is transported, it is often necessary to use a large number of transport barrels to facilitate handling and transportation. When this kind of transport bucket is actually used, in order to control the amount of cement dumped, people often need to effectively control the opening and closing degree and size of the cement cover. To ensure the size of the opening and closing caliber, it is more laborious and inconvenient. Contents of the invention [0003] Aiming at the defects of the above-mentioned technologies, the present invention proposes a rotary opening and closing cover that can effectively control the opening and closing diameter of the transport barrel when the cement is poured. [0004] A rotary opening and closing cover, which mainly includes a barr...
