Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a top structure of a hopper for storing coal, ore, or other granular materials, such as a hopper of a granular material carrier.

[Conventional technology]

As shown in FIG. 2, the powder and granular material carrier A is equipped with a hopper 1 for charging powder and granular material into a hold a, and this hopper 1 is equipped with a shooter 2 shown in FIG. 3 on its top. ing. As clearly shown in the figure, the shooter 2 is constructed by constructing lining materials 5, 5 on the left and right inclined surfaces 4, 4 forming a chevron provided on the partition member 3, respectively. It is designed to be sorted and introduced into the hold a shown in Figure 2. The upper ends of the lining materials 5, 5 of the shooter 2 are pressed against the inclined surfaces 4, 4 by a stainless steel presser member 6 having an inverted V-shaped cross section, and the partition members 3
The lining materials 5, 5 can be thermally expanded and contracted while being held between the holding member 6 and the holding member 6.

Conventionally, the presser member 6 was fixed to the partition member 3 by the structure shown in FIG. That is, the pipe material 7 is placed between the partition member 3 and the presser member 6.
The pipe material 7 was welded to both the partition member 3 and the presser member 6 to fix these three members together.

[Problem that the invention attempts to solve]

However, the pipe material 7 fixed to the partition member 3
When welding the holding member 6 to the pipe material 7, as shown in FIG. Since the through hole 8 is then placed in a helical overlay and then overlaid welded in a spiral shape to fill the through hole 8, not only the area around the through hole 8 turns brown due to welding heat, but also the pressure from the presser member 6 after welding. It is necessary to polish the raised part of the weld meat to finish the surface.
There was a problem in that it required a lot of effort and time.

In addition, the through hole 8 needs to be oval as shown in the figure in order to allow the welding rod to move easily and to have a large joint area with the pipe material 7, so drilling the hole is troublesome. There was also a problem.

[Means for solving problems]

A technical means to solve the above problem is to press the upper end of the lining material applied to the left and right slopes of the chevron shape onto the slope.
The pressing member having a letter-shaped cross section is held by a fixing pin fixed to the inclined surface.

[Effect]

According to the above means, there is no need for joining work using a welding rod and surface finishing that involves polishing, and there is also no need to drill an oval through hole in the holding member. Further, the area around the through hole of the holding member will not deteriorate due to welding heat.

〔Example〕

FIG. 1 shows the top structure of a hopper according to an embodiment of the present invention. In the figure, reference numerals 9, 9 are fixing pins, which are fixed near the upper edges of the left and right inclined surfaces 4, 4 of the partition member 3 by welding. The fixing pin 9 has a shaft portion 9a inserted through a through hole 8 formed in the holding member 6, and a collar portion 9b.
is hooked to the surface of the presser member 6. In addition, lining materials 5, 5 to be applied to the inclined surfaces 4, 4
The upper end portion of is pressed against each inclined surface 4, 4 by a pressing member 6. In addition, the above-mentioned lining material 5
is constructed to improve the slippage of the powder and granular material introduced onto the shooter 2 and to prevent wear of the partition member 3, and for example, ultra-high molecular weight polyethylene can be suitably used. Furthermore, the holding member 6 can preferably be made of corrosion-resistant stainless steel.

In such a device, if a known stud is used as the fixing pin 9, the fixing pin 9 and the partition member 3 can be welded together by arc stud welding that does not require a welding rod. Accordingly, an easy-to-drill, perfectly circular drill hole can be bored in the holding member 6, and this can be used as the through hole 8. The partition member 3 is also
The lining material 5 pressed against the lining material 5 can be thermally expanded and contracted while being held between them.

Next, in the illustrated example, a filler 10 having elasticity such as neoprene, synthetic resin foam, or the like is interposed in the space between the partition member 3 and the presser member 6. By doing so, the elasticity of the filler 10 causes the presser member 6 to be pressed against the flange portion 9b of the fixing pin 9, so there is an advantage that wobbling of the presser member 6 can be prevented.

Note that the left and right inclined surfaces 4, 4 of the partition member 3 are chevron-shaped, and the holding member 6 has an inverted V-shaped cross section, as in the conventional case. Furthermore, the structure of the shooter 2 shown in FIG. It can be easily constructed by simply arranging the holding member 6 so as to straddle it, and then arc stud welding the fixing pins 9, 9.

[Effect of idea]

As is clear from the above, the top structure of the hopper according to the present invention requires only a circular hole to be drilled in the holding member, so this hole can be easily drilled using a drill, and after welding, There is no need for surface finishing such as polishing, and furthermore, the holding member does not suffer from thermal deterioration. Therefore, the hopper shooter can be configured easily and in a short time.

The top structure of the hopper according to the present invention is of course applicable not only to powder carriers but also to other hoppers.
