Description
Technical Field
The utility model relates to an engineering machine tool accessory field, especially a light-duty scraper blade of fretwork.
Background
In the scraper reclaimer, a scraper bracket supports a chain, scrapers are arranged on the chain, and the scrapers can scrape and convey bulk materials by virtue of the moving chain.
At present, most of scrapers of a scraper reclaimer are formed by bending steel plates, the whole plate has large area and heavy weight, and particularly when large-density bulk materials are conveyed, the thickness of the scraper is increased in order to achieve local sufficient strength and rigidity, so that the weight of the scraper is further increased.
According to the calculation, the invalid energy consumed by the scraper conveyor driving the chain scraper to move accounts for 60-80% of the total consumed energy. If the weight of the scraper is heavier, the no-load driving power of the scraper is larger, and the weight of the whole scraper is directly increased, so that the manufacturing and transportation cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem, a hollow light scraper blade is designed.
The technical scheme of the utility model be, a light-duty scraper blade of fretwork, including the scraper blade body, the scraper blade body lower part is the bearing part, and upper portion is non-bearing part, the scraper blade body includes that mainboard and slope are located the curb plate of mainboard both sides, the bearing part of mainboard reduces to the thickness of its non-bearing part gradually, it has a plurality of first waist shape holes to open on the non-bearing part of mainboard, it has a plurality of second waist shape holes to open on the non-bearing part of curb plate.
Preferably, one end of the side plate, which faces away from the main plate, is provided with scraping teeth.
Preferably, a mounting plate is fixed to the back of the main board, and a mounting hole is formed in the mounting plate.
Preferably, the main plate has a trapezoidal cross section.
The utility model has the advantages that: according to the condition that the atress of bearing part is greater than the atress of non-bearing part, through being trapezoidal with the cross-sectional design of mainboard, the bearing part of mainboard reduces to the thickness of its non-bearing part gradually, makes the intensity of bearing part and non-bearing part all satisfy the operation requirement to can reduce mainboard weight, scraper blade body fretwork design sets up waist shape hole in addition, further reduces the weight of scraper blade body, thereby reaches energy-conserving effect, improves production efficiency.

Detailed Description
The invention is described in detail below with reference to the accompanying drawings, as shown in fig. 1-4: the utility model provides a light-duty scraper blade of fretwork, includes scraper blade body 1, and 1 lower part of scraper blade body is the portion of bearing, and upper portion is the non-portion of bearing, and scraper blade body 1 includes that mainboard 11 and slope are located the curb plate 12 of mainboard 11 both sides, and the portion of bearing of mainboard 11 reduces to the thickness of its non-portion of bearing gradually, and it has a plurality of first waist shape holes 111 to open in the non-portion of bearing of mainboard 11, and it has a plurality of second waist shape holes 121 to open in the non-portion of bearing of curb plate 12.
When the scraper works, the bearing part of the scraper is firstly contacted with the materials and is directly loaded by the materials, the non-bearing part is contacted with the materials after the bearing part pushes the materials to move forwards, and the non-bearing part is not subjected to extrusion and shearing loads among the materials, so that the stress of the bearing part is greater than that of the non-bearing part; according to the stress condition, the thickness from the bearing part of the main board 11 to the non-bearing part is designed to be gradually reduced, so that the strength of the bearing part and the non-bearing part can meet the use requirement, and the weight of the main board 11 can be reduced; in addition, the scraper body 1 is designed to be hollow, a plurality of first waist-shaped holes 111 are formed in the non-bearing part of the main board 11, a plurality of second waist-shaped holes 121 are formed in the non-bearing part of the side board 12, the non-bearing part is designed to be a hollow structure, normal scraping and conveying of the scraper body 1 cannot be influenced, the weight of the scraper body 1 can be reduced due to the design of the hollow structure, manufacturing materials are saved, the cost is reduced, an energy-saving effect is achieved, and the production efficiency is improved; in addition, the first waist-shaped holes 111 and the second waist-shaped holes 121 are formed instead of a large overall hollowed-out hole, so that the material can be reduced to the greatest extent and leaves away from the scraper through the large hole, and the hollowed-out holes are divided into the first waist-shaped holes 111 and the second waist-shaped holes 121, so that the overall weight of the scraper body 1 is reduced, and the scraping efficiency can be improved.
Preferably, in the present embodiment, the end of the side plate 12 facing away from the main plate 11 is provided with scraping teeth 122.
Scrape the material that tooth 122 scraped and sent the edge in the middle part inslot of conveyer, at the scraper blade transportation coal mine stone in-process, the buggy can fall into the clearance of scraping tooth 122, and the buggy can play the effect of emollient, can reduce the resistance of scraper blade body 1 operation, reduces motor power.
Preferably, in the present embodiment, a mounting plate 13 is fixed to the back of the main plate 11, and a mounting hole 131 is formed on the mounting plate 13.
The fixed mounting panel 13 quantity in mainboard 11 back is two, through setting up mounting panel 13, can be convenient for install scraper blade body 1 to scraper blade reclaimer's chain on, through connecting piece and mounting hole 131 with chain and mounting panel 13 rigid coupling.
Preferably, in the present embodiment, as shown in fig. 4, the main plate 11 has a trapezoidal cross section.
The trapezoidal section enables the thickness from the bearing part of the main board 11 to the non-bearing part to be uniformly reduced, and simultaneously enables the bearing part to the non-bearing part to bear certain load, thereby meeting the use requirements.
The utility model discloses a mainboard 11 and curb plate 12 can be casting integrated into one piece, also can be as an organic whole for welded fastening, and mounting panel 13 welded fastening is in mainboard 11 back.
Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
