Abstract
Sundries scraper plate is prevented in wheeled coal pulverizer to be transfinited the panel mounting mechanism of scraping of extruding, including the holder being fixed on mill, improvements introduced are：The holder has stretches support arm under two be oppositely arranged, axle sleeve is held in the lower end fixation that support arm is stretched under two, axle sleeve, which is held, by two assembles a shaft, fixing assembling is with axle sleeve in shaft, swing arm is being stretched under fixed on axle sleeve, scraper plate and clump weight are installed in swing arm lower end, is holding axle sleeve and is being sold with fracture of transfiniting is worn between axle sleeve.The good effect of the utility model is：It is increased by shaft, swing arm, clump weight, transfinite fracture pin bank at scrape panel mounting mechanism, scraper plate room enter excessive foreign matter, scraper plate transfinited extruding when, by the safety pin that fractures, scraper plate is able to be freely rotated around axis, and scraper plate is jacked up, bypass foreign matter.After foreign matter passes through, scraper plate resets under the action of clump weight, avoids the damage of screeding device.
Description
Technical field
The invention belongs to machinery fields, and in particular to large size with coal yard institute raw coal milling the wheeled coal pulverizer of middling speed.
Background technology
The wheeled coal pulverizer of middling speed is mainly used in thermal power plant, raw coal is worn into coal dust, and coal is being exploited or loaded and unloaded
It has often been mixed into impurity in the process, such as：Iron block, stone, wooden unit etc., these impurity can enter coal pulverizer with raw coal.Currently,
Most of thermal power plant can increase equipment for removing ferric ion in coal handling system, but effect is less desirable, also have a large amount of shape
Different iron block enters coal pulverizer.The impurity such as iron block, stone, wooden unit into coal pulverizer are eventually thrown to scraper plate room, finally
These impurity are discharged from pebble coal mouth by scraper plate, some bulks, impurity that shape is peculiar can stay in scraper plate room.Previous
The wheeled coal pulverizer screeding device of middling speed be integral solder together, can not be lifted automatically when encountering impurity, scraper plate is excessive
It squeezes, cause plate body and is damaged with the connecting elements of body, force coal pulverizer maintenance down, what is more renewed after taking-up foreign matter scrapes
Plate need to disassemble multiple components in maintenance process again, and consumable quantity is big, working hour is long, influences the normal operation of coal pulverizer, draw high coal-grinding at
This.
Utility model content
The purpose of this utility model is to provide the scraper plate peace for preventing sundries scraper plate from being transfinited extruding in a kind of wheeled coal pulverizer
Mounting mechanism, overcoming the scraper plate that is rigidly assembled in existing coal pulverizer, there are above-mentioned deficiencies.
The utility model scrapes panel mounting mechanism, including the holder being fixed on mill, improvements introduced are：The branch
Frame has stretches support arm under two be oppositely arranged, and axle sleeve is held in the lower end fixation that support arm is stretched under two, and axle sleeve assembly is held by two
A piece shaft, fixing assembling with swing arm is stretched under fixed on axle sleeve, is installed scraper plate in swing arm lower end and is matched with axle sleeve in shaft
Pouring weight is holding axle sleeve and is being sold with fracture of transfiniting is worn between axle sleeve.
The positive effect of the present invention is：The utility model it is increased by shaft, the swing arm in shaft, be mounted on pendulum
The clump weight of arm lower end, be through relative to shaft rotate hold axle sleeve and be fixed in shaft between axle sleeve transfiniting fracture pin
Composition scrape panel mounting mechanism, scraper plate room enter excessive foreign matter, scraper plate transfinited extruding when, pass through the safety pin that fractures, scraper plate
It is able to be freely rotated around axis, scraper plate is jacked up, and foreign matter is bypassed.After foreign matter passes through, scraper plate resets under the action of clump weight, avoids
The damage of screeding device reduces maintenance.
Description of the drawings
Fig. 1 is the front view of the present invention.
Fig. 2 is the side view of the present invention.
Fig. 3 is the rotation rearview of the present invention.
Specific implementation mode
Refering to fig. 1, Fig. 2, Fig. 3, the utility model scrape panel mounting mechanism, including the holder 1 being fixed on mill, are made
Improvement be：The holder has stretches support arm under two be oppositely arranged, and axle sleeve 2 is held in the lower end fixation that support arm is stretched under two,
Axle sleeve 2 is held by two and assembles a shaft 3, and fixing assembling two is stretched under fixed on axle sleeve with axle sleeve 4 in shaft 3
Swing arm 5, clump weight 6 is installed in swing arm lower end, is assembled scraper plate 7 in clump weight screwing, is being held axle sleeve 2 and worn between axle sleeve 4
Transfinite fracture pin 8.
Claims (1)
