SU30148A1 - Adaptation to inclined belt elevators for peat supply - Google Patents

Description

The upper and lower teeth 5 are installed in such a way that the smallest pieces of peat are placed between the elevator belt and the crossbars of the chains.

When feeding peat along an inclined belt elevator, an endless chain belt located below the elevator is used to keep the peat from sliding on the inclined belt. In the proposed adaptation to the inclined belt elevator for the supply of peat, in order to prevent crushing peat when they pass between the belt of the elevator and the chain web, the lower drum of the latter and the intermediate pressure rollers are installed at the ends of the levers under the action of springs so that lift to pass the peat and clamp them.

In FIG. 1 is a side elevational view and FIG. 2 - top view.

At the lower end of the upper part of the elevator, on the side walls of the chute, bearings 7 are mounted, in which shaft 2 rotates. On shaft 2, two levers 3 are mounted in the direction towards the lower end of the elevator, supporting

shaft 4 passed through them with two toothed teeth 5 mounted on the latter 5. A lever 6 held by a spring 7 is protruding beyond the bearing / shaft end 2. The same bearings 7 with shaft 8 and gears 5 are installed at the upper end of the elevator. Upper and lower teeth 5 are covered in pairs by two infinite chains 9, to the links of which are fixed at certain distances by the cross member Y.

The protruding end of the upper shaft S is connected by a gear for rotation, to the shaft 77, which is rotated by the chain transmission 72 from the elevator shaft 75, which drives the belt 14. The transmissions are calculated so that the belt J4 and the chains 9 move at the same speed.

To deflect the chains 9 down, if their own weight and tension are not enough, intermediate rollers 75 with the same parts mounted on the shaft 2 as on the shaft 2 are placed between the upper shaft 8 and the lower 2, with the only difference that these parts Smaller in size and lighter and that, together with gear 5, smooth rollers can be put, pressing on chains 9.

When the peat 16 goes over the tape, this size exceeds, then the cross-beams of the chains resting on it will raise the lower teeth 5 together with the shaft 4 and the lever 3. The rotation of the shaft 2 and the lever 6 nat no spring 7, as a result of which the peat will clamp elevator and crossbars / tf. When the peat has passed the teeth 5, they are empty to their former position under the action of the spring 7 and their own weight.

The bend of chain 9 kierhu, under the action of the leading chain, the force of the peat will be clamped all the time between the crossbars 10 and the tape 14. But, if this force is not enough, then when placing intermediate rollers 15 with a device similar to that of the shaft 2, The rollers will reinforce the clamp peat.

When passing through the lead tape, the drum on the peat shaft 13 goes out into a wide opening, obtained by setting the top lead

shaft 8 almost on the same vertical with the drive shaft 13 of the tape elevator.

The subject of the patent.

Adaptation to inclined belt elevators for the supply of peat, consisting of an endless chain belt located above the belt elevator for holding peat on an inclined belt, characterized in that, in order to prevent crushing of peat pieces as they pass between the elevator belt and the chain belt, the latter is made rotary near the axis of the Upper Chain Drum, however, ensuring proper peat hold-up by using appropriate elasticity of the springs acting on the chain web through the lever gov bearing on the free ends of the lower drum-chain, and intermediate jacking n, and blade rollers.
