Bar abrasion is larger；Furnace charge constantly impacts preceding contact surface, upper contact surface and rear contact surface in transit；Due to preceding contact surface, on
Some pits and boss are provided between contact surface and rear contact surface, so furnace charge in transit will not be complete between these faces
Full connected, and then the degree of wear between furnace charge and preceding contact surface, upper contact surface and rear contact surface is reduced, while pit and boss
It can be good at playing the role of buffering；The wearing layer that fitting projection is set can also contact first time with furnace charge, also rise
Acted on to preferable wear-resisting buffer；During long-time service, use which can be for a long time effectively reduces
The degree of wear, it is cost-effective.
The beneficial effects of the utility model are：Set again with auxiliary by the cooperation of horizontal buffer bar and longitudinal buffer bar
There is raised guarantee distributor chute can be firm wear-resisting, prolong the service life.
As further improvement of the utility model, for ensure wearing layer can much time using, can be compared with during use
Good is wear-resisting；The wearing layer in polygon set, the wearing layer be arranged on before between contact surface and upper contact surface；It is described resistance to
Layer is ground to set towards the opposite direction of Flow of Goods and Materials.
As further improvement of the utility model, to ensure that wearing layer can be durable for a long time, it is hardly damaged and comes off；It is described
Wearing layer is made of the wear resistant alloy material of high intensity.
As further improvement of the utility model, it can be come into full contact with material for guarantee protrusion and play the work of buffering
With；Set between the raised and steel matrix in 30 ° of -50 ° of angles.
As further improvement of the utility model, to ensure mutually prop up between horizontal buffer bar and longitudinal buffer bar
Support, durable；The longitudinal buffer bar is rectangle setting.
As further improvement of the utility model, to ensure that horizontal buffer bar and longitudinal buffer bar being capable of durables；
The transverse direction buffer bar is provided with some groups, and the longitudinal buffer bar is provided with four groups.
Brief description of the drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the top view of the utility model.
Fig. 3 is the side sectional view of the utility model.
Wherein, contact surface before contact surface, 3 behind 1 wearing layer, 2, contact surface on 4,5 steel matrix, 6 bases, 7 horizontal buffer bars,
