Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model; all other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model discloses an elastic mechanism for a vibrating screen, which comprises a shell 1, wherein ear plates 2 are fixedly connected to positions, close to the upper end, of two sides of the shell 1, fixing holes 3 are formed in the ear plates 2, the ear plates are fixedly connected with the vibrating screen, a fixing plate 7 is arranged in the shell 1, the fixing plate 7 is fixedly connected with a screen support frame, and elastic components are arranged on the fixing plate 7.

When this device is used, otic placode 2 rigid coupling is on the screen cloth, and fixed plate 7 rigid coupling is on the screen cloth support frame, and when the screen cloth vibrates, elastic component can take place elastic deformation to make the screen cloth vibrate from top to bottom, and filter the screening to the material.

The shape of the shell 1 ensures that materials cannot enter the spring when the device is used, thereby ensuring the long-time stable use of the spring.

The elastic component includes bracing piece 5 and spring, and bracing piece 5 runs through shell 1, and the spring is installed on bracing piece 5, and bracing piece 5 can slide in shell 1, and at the slip in-process, the spring can stretch out and draw back.

The spring comprises a first spring 9 and a second spring 11, a first mounting plate 8 and a second mounting plate 10 are fixedly connected to the supporting rod 5, the upper end of the first spring 9 is fixedly connected to the shell 1, the lower end of the first spring is fixedly connected to the first mounting plate 8, the upper end of the second spring 11 is fixedly connected to the second mounting plate 10, and the lower end of the second spring is fixedly connected to the fixing plate 7.
