DEVELOPMENT AND RESEARCH OF A DISCRETE-ACTING BATCHER WITH AN OVERTURNING BUCKET

The article deals with the issues of dosing bulk materials using weighing batchers. The existing types of batchers are described, the main disadvantages of the known discrete-acting batchers with an overturning bucket are given. A discrete-acting batcher with a tipping bucket developed by the authors is presented, its block diagram is given, according to which the principle of operation of the batcher is considered in detail. The batcher contains the following units: a feed hopper, a load receiver, upper and lower limiting supports, a counterweight, a weight measuring and display unit. The process of dosing bulk materials is reduced to the cyclical execution of four consecutive operations: feeding bulk material from the feed hopper into the load receiver below it; tilting and overturning the load receiver after reaching the set dose; abrupt stopping the tipped load receiver and unloading the dose; returning the emptied load receiver to its original position. All mechanical movements in these operations are carried out automatically and only at the expense of the potential energy of the dosed bulk material due to its weight. The second-order differential equation describing the movement of the load receiver during tipping is derived. The static equations of moments for different stages of the batcher's operating cycle are consid- ered, from which recommendations for calculating the geometric and weight parameters of the batcher are obtained.
