Abstract
The utility model discloses a novel coal mill reamer. The novel coal mill reamer is characterized in that a cutter body (1) is provided with a shaft installing hole and a bolt passing hole, a shaft (2) is provided with a bolt passing hole, and the shaft (2) is arranged in the shaft installing hole of the cutter body (1); the bolt passing holes formed in the shaft (2) and the cutter body (1) correspond to each other, a bolt (3) is arranged in the bolt passing holes formed in the cutter body (1) and the shaft (2), and a cross-shaped plate (4) is arranged on one end of the shaft (2) through a bearing base (5). The novel coal mill reamer disclosed by the utility model has the advantages that the contacting manner is changed, so that a condition that the whole reamer is positioned on the relative balance position is realized, conditions that a hanging tile is damaged, a scale is clamped and the like are avoided, and a protective device is additionally arranged.
Description
Technical field
The utility model relates to the technology of producing cement field, is specifically related to a kind of novel coal mill reamer.
Background technology
at present, existing reamer is to adopt tailing axle to inject the reamer uropore, jackscrew location with reamer uropore side, this mode, the location jackscrew is very easily loosening when reamer turns round, and then causes that tailing axle and reamer do relative motion, thereby driving reamer waves, rocks, easily cause the reamer coupling pin to twist off, hang a watt breakage, reamer distortion, the situation such as stuck occur.The coupling pin of fracture etc. enters the coal scale, and the stuck equipment breakdown of coal scale also can occur.
The utility model content
The purpose of this utility model is exactly at present, existing reamer is to adopt tailing axle to inject the reamer uropore, jackscrew location with reamer uropore side, this mode, the location jackscrew is very easily loosening when reamer turns round, and then causes that tailing axle and reamer do relative motion, thereby driving reamer waves, rocks, easily cause the reamer coupling pin to twist off, hang a watt breakage, reamer distortion, the situation such as stuck occur.The coupling pin of fracture etc. enters the coal scale, the deficiency of the generation of the stuck situations such as equipment breakdown of coal scale also can occur, and a kind of novel coal mill reamer is provided.
The utility model is comprised of blade, axle, bolt, four-bladed vane and bearing block, have axle installing hole and bolt on blade and pass through hole, have bolt on axle and pass through hole, in the axle installing hole that is arranged on blade of axle, and the bolt on axle and blade is by the hole correspondence, bolt is arranged on the bolt of blade and axle by hole, and four-bladed vane is arranged on an end of axle by bearing block.
It also has probe, and probe is arranged on the coal pulverizer body, and is positioned at the four-bladed vane below.
The utility model advantage is: the utility model is by changing the way of contact, realized allowing the position of whole reamer in relative equilibrium, avoided hanging a watt breakage, the situations such as card scale, and set up protective device.
the accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the four-bladed vane structural representation.
The specific embodiment
As shown in Figure 1, 2, the utility model is comprised of blade 1, axle 2, bolt 3, four-bladed vane 4 and bearing block 5, have axle installing hole and bolt on blade 1 and pass through hole, have bolt on axle 2 and pass through hole, in the axle installing hole that is arranged on blade 1 of axle 2, and the bolt on axle 2 and blade 1 is by the hole correspondence, and bolt 3 is arranged on the bolt of blade 1 and axle 2 by hole, and four-bladed vane 4 is arranged on an end of axle 2 by bearing block 5.
It pops one's head in 6 in addition, pops one's head in 6 to be arranged on the coal pulverizer body, and is positioned at four-bladed vane 4 belows.
Operation principle: bolt 3 runs through blade 1 and axle 2, plays fixedly blade 1 and axle 2, guarantees that blade 1 and axle 2 are on the same level line simultaneously, and four-bladed vane and probe apparatus automatic stopping when reamer is abnormal is reported to the police.
Claims (2)
