Description
Technical field
The utility model relates to the technical fields of production and transport equipment mine flight conveyer more particularly to a kind of double-strand to scrape
The scraper of plate conveyer.
Background technique
Drag conveyor is one of means of transport important in coal mining, important component of the scraper plate as drag conveyor
One of, it needs constantly to bear coarse coal and rock impact load in the production environment of underground complexity, therefore to its intensity side
The requirement in face will directly affect the safety and efficiency of production.However in actual coal mining transportational process, scraper plate it is frequent because
There is the case where abrasion is even broken and need to be replaced frequently, to increase the maintenance cost of production.Therefore it is badly in need of one kind to hold
Carry the better scraper plate of power.
Utility model content
In view of the above technical problems, it is double that the purpose of this utility model is to provide a kind of structures is simple, bearing strength is high
The scraper of chain-and-flight conveyer.
To achieve the above object, the utility model provides a kind of scraper of double chain conveyor, including scraper plate
Body and wearing plate, the bottom end for scraping plate body have the groove of indent, and one end that the wearing plate scrapes plate body described in is formed
There is the lug inlayed in the groove, scrapes plate body and lug via screw bolt passes and scrape plate body and wearing plate is fixed for described
Connection；
Described scrape also is connected with scraper chain between plate body and wearing plate.
By upper, scrape plate body and linked together with wearing plate by nested mode, and be bolted to connection；It is scraping
When plate body and wearing plate are attached with bolt, scraper chain is fixed on and is scraped between plate body and wearing plate, scrapes plate body by changing
With the connection structure of wearing plate, the area of scraper plate emphasis force part is increased, makes the average force on the position unit area
It is reduced, to improve the bearing capacity intensity of scraper plate entirety.
Preferably, the scraper plate body side surface, which is equipped with, scrapes plate body bolt connecting hole across the groove；
The lug, which is equipped with, scrapes the corresponding wearing plate bolt connecting hole of plate body bolt connecting hole with described, via bolt
It scrapes plate body bolt connecting hole and wearing plate bolt connecting hole across described and scrapes plate body and wearing plate is fixed together for described.
By upper, in such a way that bolt connecting hole is set up in side, existing double chain conveyor scraper plate is reduced because upper
It is lower to punch the mode for setting up connecting hole, and entirety reduces the forced area of scraper plate, so that unit area inside strake be made to bear
Pressure is bigger, to reduce the risk of fracture, by changing the structure and connection type of scraper plate upper and lower plates, makes scraper plate either
It bears during mining, the impact of coal breakage or the pulling force etc. during conveying coal from scraper chain all have more
Advantage keeps the integral strength of scraper plate more preferable.
Preferably, the bottom end for scraping plate body is also formed with the card slot for blocking the scraper chain；
The wearing plate is equipped with the card slot support for placing the scraper chain；
The upper horizontal surface of one of chain link of the scraper chain is nested in the card slot, and horizontal surface is attached to
In the card slot support.
By upper, guarantee that scraper chain is fixed on and scrape between plate body and wearing plate, thus scraper chain to move forwards drive entire
Scraper plate moves forwards.
Preferably, the quantity of the groove is three, and correspondingly, the quantity of the lug is three, and three lugs
Centre set there are two the card slot support；
The centre of three grooves is set there are two the card slot.
By upper, energy more stable will scrape plate body, wearing plate and scraper chain are fixed together.
Preferably, the card slot is in M-shaped, and the ring bodies for constituting the chain link of the scraper chain is entrenched in the card slot
In the recessed portion of interior two sides.
By upper, more firm scraper chain can be connected to and be scraped between plate body and wearing plate by card slot M-shaped.

Specific embodiment
It is described in detail referring to scraper of the FIG. 1 to FIG. 4 to double chain conveyor described in the utility model.
It as shown in Figs 1-4, is a kind of scraper of double chain conveyor provided by the utility model, this is practical new
The scraper of the double chain conveyor of type is mainly formed by scraping plate body 10 and wearing plate 20, wherein the bottom end for scraping plate body 10 is set
There are three grooves 11 of indent, the side for scraping plate body 10, which is equipped with, scrapes plate body bolt connecting hole 30 across the groove 11.It is wear-resisting
There are three wearing plate lug 21 on plate 20, respectively there is a wearing plate bolt connecting hole 40 on three wearing plate lugs 21, three resistance to
Wearing plate scraper chain card slot support 22 is equipped among nog plate lug 21.Wherein scrape position and the wearing plate of three grooves 11 of plate body 10
The position of lug 21 is corresponding.
When double chain conveyor work, the upper horizontal surface of one of chain link of scraper chain 50, which is nested in, scrapes plate body
In 10 scraper chain card slot 12, scraper chain card slot 12 is located at the middle position of three grooves 11, and the horizontal surface of chain link is attached to
In wearing plate scraper chain card slot support 22, wearing plate lug 21 is embedded in the groove 11 for scraping plate body 10, is made to scrape plate body and is bolted
Hole 30 and the overlapping of wearing plate bolt connecting hole 40 in the same horizontal line, and make to scrape plate body 10, wearing plate 20 by bolt 60
And scraper chain 50 is fixed together, and as moving forwards for scraper chain 50 drives entire scraper plate to move forwards.
Wherein, the scraper chain card slot 12 is in M-shaped, and the ring bodies for constituting the chain link of the scraper chain, which is entrenched in, to be scraped
In plate chain card slot 12 in the recessed portion of two sides, due to all having different angles, institute between two adjacent chain links of scraper chain 50
With when one of chain link is connected between the scraper chain card slot 12 and card slot support 22, adjacent other chain links cannot
Pass through, guarantee that scraper chain 50 is fixed on and scrape between plate body 10 and wearing plate 20, so that scraper chain 50 moves forwards drive entirely
Scraper plate moves forwards.
The utility model scrape plate body 10 and wearing plate 20 is nested together by connecting hole, and the company of being bolted
It connects.It is equipped with pressure key way between plate body 10 and wearing plate 20 in addition, scraping, and is scraping plate body 10 and wearing plate 20 is connected with bolt
When connecing, scraper chain 50 is fixed in scraper chain card slot 12.The utility model is in such a way that bolt connecting hole is set up in side, drop
Low existing double chain conveyor scraper plate is because the mode of connecting hole is set up in punching up and down, and the whole stress for reducing scraper plate
Area, so that the pressure for bearing unit area inside strake is bigger, to reduce the risk of fracture, by changing scraper plate or more
The structure and connection type of plate, make no matter scraper plate is subject to during mining, the impact of coal breakage or the mistake in conveying coal
Pulling force in journey from scraper chain etc. all has more advantage, keeps the integral strength of scraper plate more preferable.In addition, the utility model increases
The intensity of scraper plate, blade structure design is simple, relatively conventional use of at present in terms of bearing capacity to scrape through Finite Element Simulation Analysis
Plate has very big advantage, has great importance for the durability aspect of scraper conveyor scraper.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
