One of the characteristic features of the previously proposed scheme of the cam-rotor actuating member of a loading machine was the hinged attachment of the cam and its fall from a vertical position onto the pile under the action of the cam's gravity. ...

The interaction of the cam-rotor actuating member with the pile is shown schematically in the figure. The proposed methodology for determining the geometric and force parameters of a cam-rotor actuating member can be used in the design and creation of new cam-rotor loading machines.

The cam-rotor actuating member of a loading machine with cams fixed on the rotor, given the trajectory of the cam tooth, can be considered as a deaxial balanced-crank-slider planar mechanism. ...

As the initial operating position of the cam-rotor actuating member, we shall take the scheme of its operation without raising the rotor axis. We assume that the work of the rotor's gravity force is fully used for the work of penetration of the cams into the pile. The trajectory of the cam tooth in this case is a circle. ...

At interaction of the working members of loading machines with a stack, the resistance forces of the latter to penetration and separation of some volume of material are of a random, stochastic nature. This makes it difficult to determine the necessary driving forces on the working member of loading machines. The existing calculation methods address the issues of interaction with the stack of the bucket working member of the lower gripper and paired raking arms. The continuous action working member of the upper gripper has been insufficiently investigated. The questions concerning the principal features of this member and its energy parameters are touched upon only in a few works. To some extent, this is due to the indeterminate nature of the motion of the said member 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 working member: the principle of action on the stack, dimensions, shape, number of cycles per unit time. External factors have a substantial influence on productivity; they include the physical and mechanical properties of the material being loaded, the characteristics of the stack, the dimensions of the working, the organization and type of transport following the machine.

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

Engine power of the working bodies of loading machines of all types is determined approximately due to the diversity of loading conditions, properties of the material being loaded, the type of the working body performing 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 ...
