Expansion booster convenient to operate

Abstract

The invention provides an expansion booster convenient to operate. The expansion booster comprises a cone head and an operation rod connected with the cone head; the cone head is in a conical shape, a containing cavity is formed in the bottom face of the cone head, a first clamping block and a second clamping block are arranged on the side wall of the containing cavity in the generatrix direction of the cone head in a spaced manner, the second clamping block is closer to the front end of the cone head relative to the first clamping block, multiple cycling-prevention grooves communicated with the containing cavity are formed in the side face of the cone head in the circumferential direction in a spaced manner, each cycling-prevention groove penetrates the bottom face of the cone head to enable the cone head to be divided into multiple expansion blocks, a jaw face is arranged at the end, away from the cone head, of the operation rod, a containing block is arranged at the end, facing the cone head, of the operation rod, the containing block is contained in the containing cavity, and a clamping groove buckled with one of the second clamping block and the first clamping block is formed in the containing block. The expansion booster convenient to operate can rapidly and wholly remove bonding objects at the bottom of a chute.

Description

technical field [0001] The invention relates to the technical field of chute-clearing and flow-aiding devices, in particular to an easy-to-operate expansion booster, which is used to remove residual sticky matter in chutes in smelting equipment. Background technique [0002] The chute is an important link between various equipment in the smelter, and plays a vital role in the transportation and reloading of minerals. The normal flow of minerals in it is directly related to the stability of the entire production system. When the chute is transporting minerals, because the bottom of the chute is blocked by sulfur slag and other adhesives, there are materials left in the chute. Generally, the metal rods are used to pierce the materials and then hit the adhesives. Generally, the materials in the chute are relatively solid. In order to reduce resistance, The diameter of the metal rod that needs to be impacted and pierced through the material must not be too thick, and the disadva...
