Description

Striker plate and the gig of this striker plate is installed

Technical field

The present invention relates to a kind of striker plate and the gig of this striker plate is installed.

Background technology

The gig striker plate is a baffle plate of between gig head discharging opening and hopper, settling, and the material that this piece baffle plate promotes gig can get into discharging opening smoothly when discharging, prevents or reduces material to flow backwards and flow back to bottom the gig; And at present, gig striker plate commonly used has the material of the rubber of certain toughness to process again with rubber etc. is wear-resisting, and fastens through bolt clip with steel plate; Such striker plate when mounted, and the distance between hopper is about 15mm, mainly is to prevent when striker plate is run in the hopper distortion; Because of the rubber stop flitch has certain toughness, the situation that can not cause gig to be stuck, but be easy to cause the breakage of rubber stop flitch; Distance between striker plate and hopper can increase thereupon, and the rubber stop flitch generally after using 2 months, all damages and lost efficacy; Hopper in the discharging opening position become greater to 170mm to the distance between the striker plate by 15mm, if untimely replacing, the backgauge effect can be worse and worse; Material flows backwards and the material that flows back to the gig bottom gets more and more; The material of gig housing bottom is cumulative, and the buildup height of gig bottom often surpasses the height of material level protection, forces gig often to be jumped to stop and can't normal operation; Moreover, because the narrow space of striker plate installation site is changed inconvenient; Manage also not in place; In time do not repair striker plate, returning charge is more and more, causes that working current is unstable; Cause equipment often to stop, chain occurs and break and equipment breakdowns such as the gig counterweight is stuck owing to electric current overloads to jump.

Summary of the invention

The present invention provides a kind of striker plate, and it can solve the problem that easily breakage of existing striker plate, backgauge weak effect, service life are lacked.

In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted is: it includes baffle plate, is set side by side with two guide plates on the said baffle plate, and said guide plate is a trapezoid body; The upper surface of said baffle plate is provided with wearing layer, and the outside face of said guide plate is provided with wearing layer.

In the technique scheme, scheme is more specifically: two said guide plates are separately positioned on the distance sixth to three of the baffle plate termination/place separately on the said baffle plate;

Further: the bottom of one of them guide edge of said guide plate is concordant with the outer side edges of said baffle plate; Another guide edge of said guide plate and the driving surface of said baffle plate intersect; Its angle is 110 °～120 °, and the angle at the said guide edge top concordant with the outer side edges of said baffle plate is that radius R is 25 millimeters～40 millimeters a arc chord angle.

The present invention provides a kind of gig that above-mentioned striker plate is installed, and it can solve the problem of existing gig power consumption.

In order to address the above problem; The technical scheme that the present invention adopted is: include housing, gig discharging opening, hopper and striker plate; Said striker plate includes baffle plate; The bottom of one of them guide edge of the guide plate that is equipped with on this baffle plate is concordant with a side of said baffle plate, and this side is the baffle plate lateral surface, and the face relative with said baffle plate lateral surface is the baffle plate medial surface; Said baffle plate medial surface tilts to be welded on the said gig discharging opening through first weld seam, and it is fixing that said baffle plate both ends of the surface are passed through the welding of second weld seam and the 3rd weld seam and said housing two sides respectively.

Further: said face of weld is provided with wear-resisting layer, and said weld bead height is that H is 12 millimeters～14 millimeters, and said wear-resisting layer thickness h is 2 millimeters～3 millimeters.

Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:

1, backgauge is effective; Power consumption is low: owing to be set side by side with two guide plates on the baffle plate, guide plate is a trapezoid body, and the distance of guide plate top outside hopper is greater than 10mm; As long as swing or the hopper of gig hopper when work is out of shape when being no more than 10mm, hopper can not run into striker plate; The gig hopper is when the swing in when work or hopper distortion surpass 10mm, and hopper can be run into the guide plate of striker plate earlier and along the trapezoidal guide direction motion of guide plate, can not snap onto in the baffle plate of striker plate and cause the gig stuck phenomenon; Therefore this striker plate can be done very for a short time from the distance of hopper outside; Be that distance between striker plate and hopper can be at 5 mm～10mm,, reduce gig material refluence area of passage because the distance between this striker plate and hopper is very little; The backgauge better effects if; Actv. reduces the material refluence and flows back to bottom the gig, the idle work of doing thereby the minimizing gig promotes this partial material once more, the work power consumption of reduction gig.

2, long service life: because this striker plate surface is provided with the build-up wear-resistant layer; Mill layer thickness is 2 millimeters～3 millimeters; Superficial hardness is about HRc50, can reduce material to the erosive wear of striker plate and the skimming wear of hopper and guide plate, and the life-span reached more than 2 years.
