Pull and take off grain device

Abstract: The utility model discloses a pull and take off grain device, it includes: flexible conveyer and pull grain raking machine rather than the lower extreme articulated, pull grain raking machine and include: a belt conveyor, grain raking machine constructs, move gyration elevating system, it sets up in a belt conveyor's middle part below, and it includes: the runing rest, an elevating devic Slewing bearing, a gear motor, it is rotatory that it drives slewing bearing through drive gear, remove the base, it is removed by motor drive to it all around moves to make the removal base drive a belt conveyor, pull rotation mechanism, it sets up the discharge gate department in belt conveyor upper end, and it includes: the carousel fixed plate, first turntable bearing, hosting frame fixed plate, and the gallows, be equipped with the round pin shaft hole on it to it is articulated through round pin axle and flexible conveyer that the messenger pulls grain raking machine The utility model has the advantages of gathering range is big, and it is efficient to take off grain, and extensive applicability saves time, and is laborsaving

Furnace top chute distributing device for blast furnace

Abstract: The utility model discloses a furnace top chute distributing device for a blast furnace, comprising an airtight box body, a throat pipe, an upper slewing bearing, a chute, a universal frame, a lower slewing bearing, a shifting wheel assembly, a cylinder and a horizontal driving device which drives the upper slewing bearing to rotate, wherein the throat pipe penetrates a top cover arranged at the top of the aright box body to be inserted into the aright box body; the inner ring of the upper slewing bearing is connected with the top cover; a rotating sleeve is connected with the outer ring of the upper slewing bearing, the rotating sleeve is provided with a lug, and the chute is suspended in the rotating sleeve by virtue of the lug; the lug is connected with one end of a crank; the other end of the crank is arranged in a sliding slot of the universal frame; the inner ring of the lower slewing bearing is connected with the universal frame; one end of the shifting wheel assembly is connected with the inner ring of the lower slewing bearing, and the other end of the shifting wheel assembly is arranged in the sliding slot of the rotating sleeve; and the cylinder is used for dragging the lower slewing bearing to move up and down. The furnace top chute distributing device for the blast furnace disclosed by the utility model is reasonable in structure, long in service life, shortest in transmission chain and more stable in operation and can not produce a lateral force to a guide rail.

Full-automatic carrier roller production equipment

Abstract: The invention provides full-automatic carrier roller production equipment The full-automatic carrier roller production equipment comprises a base and a first slewing bearing Second slewing bearings are arranged at the upper end of the base through sliding plates and move according to the length of carrier rollers After the second slewing bearings move in place, two shells are connected through a fixing worktable The first slewing bearing and the second slewing bearings are in drive connection with first servo motors When the full-automatic carrier roller production equipment is in use, the first servo motors drive the whole first slewing bearing and the second slewing bearings to rotate, meanwhile, eight chain wheels and a ninth fixing chain wheel fixed to the first slewing bearing rotate along with the first slewing bearing and the second slewing bearings, the fourth chain wheel and the eighth chain wheel drive the other chain wheels to complete autorotation through a chain under the acting force of the ninth fixing chain wheel, and rotation of the eight chain wheels keeps eight carrier roller supports upward all the time through the second slewing bearings The full-automatic carrier roller production equipment has the advantages that roller manufacturing efficiency is significantly improved, the manufacturing process is sophisticated, time and labor are saved, and the full-automatic carrier roller production equipment is suitable for producing carrier rollers of various specifications
