screw hopper

Abstract

The invention relates a spiral hopper. The spiral hopper comprises a barrel which is arranged outside a vertical lifting barrel, partially coincides with the vertical lifting barrel and is connected with the vertical lifting barrel in a sealed mode, an annular cavity is formed between the barrel and the vertical lifting barrel, an annular feeding port is formed in the upper portion of the cavity, and a discharging port is formed in one side of the lower portion of the cavity; two long spiral slide ways are arranged in the cavity, the upper ends of the long spiral slide ways are connected with the feeding port, and the lower ends of the long spiral slide ways are connected with the discharging port; two short spiral slide ways are arranged in the cavity, the upper ends of the short spiral slide ways are connected with the feeding port, and the lower ends of the short spiral slide ways extend to the long spiral slide ways. According to the spiral hopper, the spiral slide ways are arranged in the barrel, materials entering the spiral hopper from the feeding port slide down to the discharging port along the long spiral slide ways and the short spiral slide ways respectively, therefore, buffering is achieved, and material breaking is avoided.

Description

【Technical field】 [0001] The invention relates to a hopper. 【Background technique】 [0002] In the chain bucket ship unloader, the hopper is set outside the vertical hoisting cylinder, partially overlapped with the vertical hoisting cylinder and connected in a sealed manner, and serves as a transition to accept the materials in the bucket elevator and transport the materials to the conveyor belt conveyor below the hopper effect. The currently used hopper usually includes a cylinder, which is arranged outside the vertical lifting cylinder, overlaps with the vertical lifting cylinder and is sealed and connected. An annular cavity is formed between the cylinder and the vertical lifting cylinder. The upper part of the cavity is The feed port, the discharge port at the lower part of the cavity. The disadvantage is that when the material falls from the feed port of the hopper to the discharge port, due to the large drop, the material is easily broken. 【Content of invention】 ...
