Problems solved by technology
The current sampling method is to take a bag of samples directly at the exit of the vibrating sieve. At this time, the sampling is only a sample at a time point, not a sample for a long period of time, and cannot truthfully reflect the product quality in a long period of time.

The invention relates to a vibrating screen with a sampling apparatus. The vibrating screen is arranged just below an opening of a grain cutting machine, and comprises a vibrating screen support and a screen surface with a plurality of screen meshes arranged on the support. The screen surface comprises an upper layer screen surface and a lower layer screen surface. A product outlet is arranged at one end of the lower layer screen surface. A sampling port is arranged between the product outlet and the screen meshes of the lower layer screen surface. The sampling device is arranged below the sampling port and comprises: a sampling adjusting valve and a sampling container arranged below the sampling valve. The sampling adjusting valve comprises two concave slots adhered on the bottom of the lower layer screen surface, and an adjusting valve plug board arranged between the slots. The plug board can horizontally slide along the concave parts of the slots. In the vibrating screen provided by the invention, the sampling speed and the sampling time are controlled through the sampling adjusting valve. The samples can be gathered at any time while the qualified products are collected, thus being convenient to collect the products at different time, and ensuring to reflect the true quality of products.
Description
technical field [0001] The invention relates to a vibrating screen, in particular to a vibrating screen with a sampling device. Background technique [0002] The vibrating screen device is an important process equipment in the modified plastics industry. Its main function is to screen the columnar finished products cut out by the pelletizer to remove the long pellets and powder. [0003] In the production of modified plastics, it is often necessary to sample the mechanical properties of the product and check whether the color of the product meets the customer's requirements. The current sampling method is to take a bag of samples directly at the exit of the vibrating sieve. The sampling at this time is only a sample at a time point, not a sample for a long period of time, and cannot truthfully reflect the product quality in a long period of time. Contents of the invention [0004] The invention provides a vibrating sieve with a sampling device. The vibrating sieve is prov...
