Abstract

The utility model relates to the field of machinery, in particular to a feed frame. The technical scheme of the feed frame is that the feed frame comprises a support seat, a support rod fixed on the support seat, a bearing plate which is arranged at the upper end of the support rod and provided with a rolling groove in the middle, two pairs of bearing supports which are fixedly arranged on the bearing plates, and pulleys hinged between the opposite bearing supports. The support rod comprises a sleeve which is fixed on the support seat and provided with a first through hole, a lifting rod which is in insertion connection with the sleeve and provided with a second through hole and a pin matched with the first through hole and the second through hole to fix the lifting rod. The feed frame has the advantages of being adjustable in height to meet current machining height, being simple in operation and improving production efficiency.

Description

Discharging frame

Technical field

The utility model relates to mechanical field, particularly discharging frame.

Background technology

Discharging frame of the prior art, it is highly often unadjustable, so that in process, in order to satisfy the requirement of current working height, usually will change discharging frame, and therefore, comparatively trouble has also reduced production efficiency.

The utility model content

The purpose of the utility model provides discharging frame, and it has adjustable for height characteristics, so that satisfy current working height demand, and simple to operate, improved production efficiency.

The above-mentioned technical purpose of the utility model is achieved through following technical scheme: discharging frame; Comprise bearing, be fixed in support bar on the bearing, be fixed in support plate that post upper and middle part have slot rolling, be fixedly arranged on two pairs of bearing blocks on the support plate, be articulated in the roller of tackling mutually between the bearing block, said support bar comprises the sleeve pipe that is fixed on the bearing and has through hole one, peg graft with sleeve pipe and have the elevating lever of through hole two, through cooperating pin with through hole two with the fixed elevated bar with corresponding through hole one.

Preferred as the utility model, said roller outer wall is covered with rubber layer.

In sum, the utlity model has following beneficial effect: through pin being inserted in corresponding through hole one and the through hole two realizing the adjusting of elevating lever height, thereby when working height was sent out variation, the utility model still can satisfy the requirement of current working height.
