Abstract
The utility model relates to a middle slot of a scraper feeding machine, in particular to a middle slot of a low height pin connector scraper conveyer which includes a baffle end cut (2) and a pin rail seat (1); the utility model is characterized in that a hole is arranged on the baffle end cut (2); the pin rail seat (1) is fixed in the hole; the technical scheme adopted by the utility model solves the technical problem that the height of a heavy scraper conveyer used for exploring a thin coal layer working surface is restrained and reduces the requirements for the integral matching height. The utility model adopts a middle slot pin connector embedded structure which not only meets the requirements for the aspects like the traction of a coal cutter, the intensity of a pin rail, the thickness of a middle plate and the specification of a chain, but also can reduce the requirements for the integral matching height to large extent; the utility model provides a reasonable novel structure with reliable property and high adaptation to a large power heavy scraper feeding machine.
Description
Technical field
The utility model relates to a kind of The middle pan of scraper conveyor, especially low clearance pin row seat The middle pan of scraper conveyor.
Background technology
At present, the slat conveyer that China's thin seam mining uses forms by common slat conveyer transformation, or directly uses small-sized slat conveyer.Type is old, and freight volume and installed power are little, the fault rate height.Common The middle pan of scraper conveyor structure mostly is cast welding back cover structure, and intermediate channel pin row holder structure is helped for directly being located in the intermediate channel baffle plate groove.Be subjected to factor affecting such as the requirement of shearer haulage power, pin row intensity, middle plate thickness, chain specification, pin row seat height decline space under the situation of existing intermediate channel structure is very limited.Add the restriction of thin seam working surface geologic condition, China's existing thin seam mining use equipment mostly is miniwatt, little type equipment.And China's most of mining area ocurrence of coal seam characteristics be thick-thin alternate, girdle occupies larger proportion in the coal total storage.Thin seam mining speed is slow, causes lower floor's coal resources to overstock, and can not get exploitation for a long time.Along with the increase of coal resources exploitation velocity and the requirement of coal resources exploitation safety, thin seam mining also will use high-power heavy scraper conveyor.
Be subjected to the restriction of thin seam working surface height, the complete machine height of hydraulic support, coalcutter, heavy scraper conveyor is restricted, use the supporting requirement that can't satisfy whole supporting height of existing The middle pan of scraper conveyor pin row holder structure and coalcutter, in order to reduce the supporting height of intermediate channel and coalcutter, emphasis is exactly the height problem that solves the pin row seat.
The utility model content
The purpose of this utility model provides a kind of low clearance pin row seat The middle pan of scraper conveyor, has realized reduction pin row seat pin hole center height on the pin row seat intensity based not reducing, and its rational in infrastructure, dependable performance is particularly useful for thin seam mining.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of low clearance pin row seat The middle pan of scraper conveyor comprises baffle plate ledge and pin row seat, and its special feature is, helps at described baffle plate groove and has the hole, and the pin row seat is fixed in this hole.
The pin row seat bottom surface that wherein contacts with the baffle plate ledge is stepped.
Further, wherein pin row seat and baffle plate ledge welding.
The technical solution adopted in the utility model has solved the technical matters that the height-limited system of heavy scraper conveyor is used in the thin seam working surface exploitation, reduces the requirement of whole supporting height.Adopt conveyer intermediate channel pin row seat embedded structure, can satisfy the requirement of factors such as shearer haulage power, pin row intensity, middle plate thickness, chain specification, can significantly reduce the requirement of whole supporting height again, for thin seam mining uses that high-power heavy scraper conveyor provides rationally, dependable performance, a kind of new structure that applicability is strong.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model background technology;
Accompanying drawing 2 is a structural representation of the present utility model.
The specific embodiment
Come the utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 2, the utility model is on original pin row seat basis, do not reducing on pin row seat 1 intensity based, by changing the shape of pin row seat 1 bottom surface, change the joint form of pin row seat 1 and intermediate channel, wherein pin row seat 1 bottom surface is processed into steppedly, and intermediate channel baffle plate ledge 2 is processed into the square hole shape in the relevant position, makes pin row seat 1 be embedded in 2 li of intermediate channel baffle plate ledges.
Claims (3)
1, a kind of low clearance pin row seat The middle pan of scraper conveyor comprises baffle plate ledge (2) and pin row seat (1), it is characterized in that: have the hole on described baffle plate ledge (2), pin row seat (1) is fixed in this hole.
2, low clearance pin row seat The middle pan of scraper conveyor as claimed in claim 1 is characterized in that: pin row seat (1) bottom surface that wherein contacts with baffle plate ledge (2) is stepped.
3, low clearance pin row seat The middle pan of scraper conveyor as claimed in claim 1 or 2 is characterized in that: wherein pin row seat (1) welds with baffle plate ledge (2).
