Description

Technical Field

[0001] The utility model relates to an openable silo protective cover plate. Background Art

[0002] Generally, multiple material storage bins are designed in the pre-processing stage of a production line. To facilitate unloading by dump trucks, the material storage bins are usually arranged side by side below the ground, and most of them are not designed with covers. Summary of the invention

[0003] The purpose of the utility model is to provide an openable silo protective cover to effectively block direct contact between materials and the surrounding environment, improve on-site sanitary conditions, and achieve the purpose of safe and environmentally friendly storage.

[0004] The specific technical scheme of the utility model is: an openable silo protective cover, comprising a fixed leg and a protective cover, a rotating shaft is arranged on the fixed leg through a bearing seat, a driving rotating arm is arranged on both sides of the rotating shaft, the free ends of the driving rotating arms are respectively hinged on the two side walls of the protective cover, and a supporting roller is arranged on both sides of the far end of the protective cover; a two-way locking manual winch is arranged at one end of the rotating shaft.

[0005] The silo protective cover adopts a light structure with a skeleton. Support rollers are designed on both sides of the ends of the protective cover. During the flipping process of the protective cover, the support rollers always fit the top plane of the silo and roll backward along the top plane. Opening and closing are achieved by a set of manual winches driving the rotating arm through the rotating shaft. The manual winch has a two-way self-locking function, and the protective cover can stay at any position. The manual winch can realize torque amplification, and one person can easily operate to open and close the protective cover.

[0006] Compared with the prior art, the advantages of the utility model are: 1. The structure is novel, and the protective cover does not occupy the surrounding space during opening; 2. The protective cover only needs a set of manual winches (which can also be changed to electric drive) to open and close, which is simple to install and has low difficulty in processing and manufacturing parts; 3. The structure is simple, the operation is stable and reliable; 4. It is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] 1. Protective cover; 2. Driving arm; 3. Fixed support leg; 4. Bearing seat; 5. Rotating shaft; 6. Two-way locking manual winch; 7. Support roller. DETAILED DESCRIPTION

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] In the above-mentioned Figure 1 In: An openable silo protective cover comprises a fixed leg 3 and a protective cover 1, a rotating shaft 5 is arranged on the fixed leg 3 through a bearing seat 4, a driving rotating arm 2 is arranged on both sides of the rotating shaft 5, the free ends of the driving rotating arm 2 are respectively hinged on the two side walls of the protective cover 1, and a supporting roller 7 is arranged on both sides of the far end of the protective cover 1; a two-way locking manual winch 6 is arranged at one end of the rotating shaft 5.

[0013] Equipment working process: The hand-cranked manual winch 6 drives the rotating shaft 5 and the driving arm 2 to rotate, and the driving arm drives the protective cover 1 to start flipping. The supporting rollers 7 on both sides of the end of the protective cover 1 always move backward along the top plane of the silo; the manual winch 6 has a two-way self-locking function, and the flipped protective cover can stay at any position. If you need to close the protective cover 1, just crank the manual winch 6 in the reverse direction, and the protective cover 1 can return to its original position.
