Description

. The invention relates to the mining industry, in particular to the executive bodies of the auger combine harvesters and | Aban type, and intended to control the loads generated during the destruction of a coal seam by the executive bodies of combines, movements of the combine in the formation profile, as well as to measure torque and three total components of the forces acting on the executive body in experimental studies, and is an improvement to the auth. No. 1104259. The purpose of the invention is to ensure the effectiveness of the management of the executive body in the course of work. Fig. I shows the executive body, side view; figure 2 - section aa in figure 1 ;, in fig.Z - section bb in figure 2; figure 4 - section bb In 4mg.2; on Lig.5 - sweep groove 7; figure 6 - scan groove 8; figure 7 - section GG in figure 2; Fig. 8 is a diagram of the connection of the sensors; Fig. 9 is a block diagram of a mining machine control system. The executive body of the mining machine includes a housing 1 with fists 2 fitted with incisors 3. The housing 1 is attached to the flange 4 of the measuring sleeve 5, executed in the form of a hollow cylinder with internal splines 6. Between the slots 6 and the flange 4 there are two grooves 7 and 8. On the groove 7, sensors 9, 13, and 15 are fastened, and 14, and 16, 20, at the groove 8, an annular groove 21 is made on the flange 4 of the measuring sleeve 5, in which additional sensors 22, 25 are fastened. Sensors 9-12 are designed, just like sensors 22 - 25 for measuring the total axial component of the perturbation force R. To increase the sensitivity of the measuring sleeve 5, sensors 11, 12 and 24, 25 have opposite (practical) conductance to sensors 9,10,22 and 23. Sensors .13, 14 and 15, 16 are designed respectively for measuring the components P and Q. independence of fixing the values of P and 5 from the point of their application on the executive body, the sensors 13 and 15 are located on the groove 7, and the sensors 14 and 16 on the groove 8. The sensors 17 - 20 are located at an angle of 45 to the longitudinal axis 2 of the sleeve 5 and are designed to measure transmission torque Workers 9-20 and 22-25 interact with the machine control system. The mining machine control system consists of a comparison element 26 and an amplifier (if necessary, a control signal gain), a transmission device 28, an actuator 29 and a sensing element 30. The sensing moment is performed by the measuring sleeve 5. The device operates as follows. The executive body, on the body 1 of which the fists 2 are fitted, equipped with the cutters 3, destroys the coal mass. When the actuator interacts with the bottom, through the flange 4 on the measuring sleeve 5 there are three total components of the disturbance forces P, Q, R and the torque M, which cause deformation of the grooves 7 and 8 and the annular groove 21, sensed respectively by sensors 9-20 and 22-25, which produce signals proportional to the deformations. The components (the forces perturbed P and Q, which bend the measuring sleeve 5, are fixed respectively by sensors 13, 14 and 15, 16. Component R, compressing 1 measuring sleeve 5 and the bending ring groove 21 on the flange 4, ({mixed by sensors 9 - 12 and 22 - 25. Sensors 17–20 4iksiruyuschiye SPINS1SPh.Yi moment / L. Electrical signals P are sent to the comparison element 26, the signal P is also applied to the latter, which the system is tuned to before starting operation. mismatch signal Pp-P., - R. This signal when neo is amplified by the amplifier 27 and through the transfer device 28 is fed to the executive mechanism 29, which works out the mismatch until the equality "-P" is reached. In addition, signals from sensors 9-20 and 22-25 can be fed to the recording equipment when conducting mining or bench surveys of mining machines. Measurement of the three total components of the perturbation forces P, Q and R and a circle

At the moment, M permits the effective efficiency of the executive body to regulate the height of the executive of the soil of the reservoir, as well as the skull of the reservoir in terms of the thickness of the reservoir and the feed rate of the mining machine.
