Aggregate storage bin with spiral propeller

Abstract

The invention discloses an aggregate storage bin with a spiral propeller. The aggregate storage bin with the spiral propeller comprises a measuring belt conveyor, a frame, a hopper body, a second front added board, a second rear added board, a form vibrator and the spiral propeller, wherein the measuring belt conveyor is arranged on the inner side of the frame; the measuring belt conveyor is fixedly connected with the frame through a bolt; a backing plate is arranged between the bolt and the frame; the hopper body is fixedly mounted at the top end of the measuring belt conveyor; the measuring belt conveyor is communicated with the hopper body. The aggregate storage bin with the spiral propeller has the advantages that the frame is made of a carbon steel material, the overall stability is good, the rigidity is high, the frame is subjected to rust removal and oil removal treatment, the surface of the frame is coated with red priming paint, the outer surface of the red priming paint is coated with orange finish paint, the frame is protected, and the frame can be prevented from being rusted after long-term use; a rubber sealing ring is arranged in a position where the hopper body is in contact with the spiral propeller, the sealing property between the hopper body and the spiral propeller is enhanced, and leakage of grain is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment application, in particular to an aggregate bin with a screw. Background technique [0002] In the prior art, aggregate silos with screw propellers are mainly used in extrusion equipment. Multiple sets of screw propulsion reamers are installed on the rotating shaft sleeve, and then installed in the machine body with material inlet and outlet. It enters from the feed port, and is finally extruded from the discharge port after being propelled by the helical propelling reamer of the screw propeller and frictionally pressurized. The spiral propulsion reamer constantly pushes and rubs the material. During this process, the propulsion surface of the spiral propulsion reamer is very stressed and wears out very quickly. The wear resistance of the rotary propulsion reamer is stronger than that of the spiral blade. When the blade wears to a certain thickness, the blade will be broken under the ...

AI Technical Summary

Problems solved by technology

The spiral propulsion reamer constantly pushes and rubs the material. During this process, the propulsion surface of the spiral propulsion reamer is very stressed and wears out very quickly. The wear resistance of the rotary propulsion reamer is stronger than that of the spiral blade. When the blade wears to a certain thickness, the blade will be broken under the reaction of the thrust. On the contrary, the more capricious spiral blade made by the rotary propulsion reamer will have poor wear resistance. In short, the wear surface of the rotary propulsion reamer reaches 10% of the total volume. scrapped in a while
