Abstract

The invention discloses a material blocking plate and a lifting machine with the material blocking plate. The material blocking plate comprises a baffle, wherein two guide plates are arranged on the baffle in parallel; the guide plates adopt ladder-shaped bodies; and wear-resistant layers are formed on the upper surface of the baffle and the outer surfaces of the guide plates. The lifting machine comprises a housing, a discharge port of the lifting machine, a hopper and the material blocking plate, wherein the material blocking plate comprises the baffle; the lower part of the guide edge of one of the guide plates mounted on the baffle is flush with one side surface of the baffle; the side surface is the outer side surface of the baffle; the surface opposite to the outer surface of the baffle is the inner side surface of the baffle; the inner side surface of the baffle is obliquely welded onto the discharge port of the lifting machine through a first welding seam; and the two end surfaces of the baffle are fixedly welded with the two side surfaces of the housing through a second welding seam and a third welding seam respectively. Compared with the prior art, the material blocking effect is good, the service life is more than 2 years and the working power consumption is low.

Description

Striker plate and be provided with the gig of this striker plate

Technical field

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

Background technology

Gig striker plate is the one piece of baffle plate settled between gig head discharging opening and hopper, and the material that this block baffle plate makes gig promote can enter discharging opening smoothly when discharging, prevents from or reduce material flowing backwards and flowing back to bottom gig, and at present, conventional gig striker plate rubber etc. are wear-resisting has again the material of the rubber of certain toughness to make, and fastened by bolt clip with steel plate, such striker plate when mounted, and the distance between hopper is about 15mm, mainly prevent when striker plate is encountered in hopper distortion, because rubber stop flitch has certain toughness, the situation that gig is stuck can not be caused, but be easy to the breakage causing rubber stop flitch, distance between striker plate and hopper can increase thereupon, rubber stop flitch is generally in use after 2 months, whole damage was lost efficacy, distance between hopper in discharging opening position to striker plate become greater to 170mm by 15mm, if change not in time, backgauge effect can be worse and worse, material flows backwards and the material flowed back to bottom gig gets more and more, the material of gig housing bottom is cumulative, buildup height bottom gig often exceeds the height of material level protection, force the frequent stop jumping of gig and cannot normally work, moreover, due to the narrow space of striker plate installation site, change inconvenient, manage also not in place, do not repair striker plate in time, returning charge gets more and more, and causes working current unstable, cause the equipment often stop jumping due to current overload, occur the equipment breakdowns such as the disconnected and gig counterweight of chain is stuck.

Summary of the invention

The invention provides a kind of striker plate, it can solve the easily breakage of existing striker plate, backgauge weak effect, service life short problem.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: it includes baffle plate, described baffle plate is set side by side with two pieces of guide plates, and described guide plate is trapezoid body, the upper surface of described baffle plate is provided with wearing layer, and the outside face of described guide plate is provided with wearing layer.

In technique scheme, scheme is more specifically: two pieces of described guide plates are separately positioned on 1/1 to three/6th place of distance on described baffle plate baffle plate termination separately;

Further: the bottom of one of them guide edge of described guide plate is concordant with the outer side edges of described baffle plate, another guide edge of described guide plate is crossing with the driving surface of described baffle plate, its angle α is 110 ° ~ 120 °, to be radius R be at the angle at the described guide edge top concordant with the outer side edges of the described baffle plate arc chord angle of 25 millimeters ~ 40 millimeters.

The invention provides a kind of gig being provided with above-mentioned striker plate, it can solve the problem of existing gig power consumption.

In order to solve the problem, the technical solution adopted in the present invention is: include housing, gig discharging opening, hopper and striker plate, described striker plate includes baffle plate, the bottom of one of them guide edge of the guide plate that this baffle plate is equipped with is concordant with a side of described baffle plate, this side is baffle plate lateral surface, the face relative with described baffle plate lateral surface is baffle plate medial surface, described baffle plate medial surface passes through the first weld seam oblique weld on described gig discharging opening, described baffle plate both ends of the surface are welded and fixed respectively by the second weld seam and the 3rd weld seam and described housing two sides.

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

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

1, backgauge is effective, power consumption is low: owing to baffle plate being set side by side with two pieces of guide plates, guide plate is trapezoid body, and guide plate top is greater than 10mm from the distance outside hopper, as long as when the swing operationally of gig hopper or hopper distortion are no more than 10mm, hopper can not encounter striker plate, when the swing operationally of gig hopper or hopper deform more than 10mm, hopper first can encounter the guide plate of striker plate and the trapezoidal guide direction along guide plate is moved, gig stuck phenomenon is caused in the baffle plate that can not snap onto striker plate, therefore this striker plate can do very little from the distance outside hopper, namely the distance between striker plate and hopper can at 5 mm ~ 10mm, because the distance between this striker plate and hopper is very little, reduce gig material retrograde passage area, backgauge better effects if, actv. reduces material and flows backwards and flow back to bottom gig, thus the idle work reducing gig again to promote this partial material and do, reduce the work power consumption of gig.

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