One of the characteristic features of the previously proposed scheme of the rowing-rotor actuator of a loading machine was the articulated engagement of the rower and its fall from a vertical position on the stack under the action of the gravity of the rower. ...

The interaction of the comb-rotor actuator with the stack is shown schematically in figure. ...

The rowing-rotor actuator of a loading machine with rows fixed on the rotor at a given trajectory of the rowing tooth can be considered as a deaxial balancer-slider planar mechanism. ...

As an initial position of work of the rowing-rotor actuator we shall accept the scheme of its work without lifting of the rotor axis. We consider that the work of the rotor gravity force is fully utilized for the work of introduction of combs into the stack. The trajectory of the comb tooth in this case is a circle. ...

At interaction of gripping bodies of loading machines with the stack of resistance forces of the latter to the introduction and separation of some volume of material are random, stochastic nature. This makes it difficult to determine the necessary driving forces on the actuator of loading machines. The existing methods of calculations touch upon the issues of interaction with the stack of the bucket actuator of the lower gripper and paired raking tines. The continuous acting actuator of the upper gripper is insufficiently investigated. The questions concerning principal features of this body and its energy parameters are touched upon only in a few works. To some extent, this is due to the uncertain nature of the motion of this organ when interacting with the stack, which makes it difficult to consider its kinematics, and hence the determination of forces in the links, not to mention the dynamics of loading...

The main indicator of a mine loading machine is its technical productivity, which depends on many factors. These include, first of all, factors characterizing the machine itself and especially its actuator: the principle of impact on the stack, size, shape, number of cycles per unit of time. Substantial influence on productivity have external factors, which include physical and mechanical properties of the loaded material, the characteristics of the stack, the size of the excavation, the organization and type of transport following the machine.

When studying the executive organ of the rowing-rotor loading machine for recording the forces on the oscilloscope was made and applied rheostat sensor mounted on the indicator head of the clock type, which was attached to the dynamometer and recorded the change in the position of its spring.

Engine power of the working bodies of loading machines of all types is determined approximated due to the diversity of loading conditions, properties of the loaded mass, the type of the working body, producing loading, etc. ....

One of the ways to develop and improve loading mechanisms is to identify and introduce into practice the most rational form and kinematics of the working bodies of existing loading machines. However, the desire to intensify work causes the search for other ways to increase the efficiency of loading mechanisms ...
