FIG. one

The invention relates to the equipment of the baking industry, in particular to the construction of conveyor hearths of ovens of dead-end and tunnel type.

The aim of the invention is to increase the reliability of operation and reduce the metal intensity of the hearth.

FIG. 1 shows a diagram of the conveyor hearth; in fig. 2 - podik, top view.

The conveyor belt to dead-end and tunnel type furnaces consists of two endless lamellar chains 1 with asterisks 2 and 3 rigidly fixed on shafts 4, and pegs 5, each of which is attached to chains 1 with two fingers 6 and 7 located on them end walls. The fingers 6 and 7 of each subsyon are located on opposite sides with respect to its longitudinal axis at an equal distance from it B. The shafts of 4 stars 2 and 3 are cantilevered, and the axes of the asterisks of one chain are offset relative to the axes of the asterisks of the other chain in the horizontal plane by equal to 2B, i.e. the distance between the points of attachment of the podik’s fingers to the chains.

Under works as follows.

When the chains of the conveyor 1 move 5, they maintain a constant horizontal position, since this is facilitated by fastening them to the chains 1 with the fingers 6 and 7, which are located on opposite sides relative to the longitudinal axis of the peaks, at a distance equal to it. With the passage of two extreme pairs of asterisks 2 or 3, whose axes are displaced, podiki 5 pere-

the movement on the lower branch of the chain 1 of the conveyor, thus changing the direction of its movement to the opposite and maintaining a fixed horizontal position. When the second pair of sprockets reaches 3 or 2, the pod 5 moves back to the upper branch of the conveyor and the cycle repeats,

The features of fastening the poles to the chains and placing the sprockets provide a fixed horizontal position of the pockets on all branches of the conveyor, which means that the reliability in the operation of the conveyor hearth furnaces increases, its intensity is reduced by eliminating the side cradles and simplifying the design of the shafts.

Claims (1)

Claims of the invention The conveyor belt to dead-end and tunnel type furnaces contains two infinite lamellar chains with asterisks rigidly fixed on the shafts and planks, each of which is attached to the chains with two fingers located on their end walls, characterized in that in order to increase reliability in operation and reduce the metal intensity of the hearth, the fingers of each shaft are located on opposite sides of its longitudinal axis at an equal distance from it, the shafts of the sprockets are strengthened with a cantilever, and the axes of the sprockets are second circuit are shifted relative to the other chain Stars axes in the horizontal plane by an amount equal to the distance between the points of attachment to fingers podika chains.
