JIGGING MACHINE USING THE DRIVE SYSTEM
TECHNICAL FIELD
This solution relates to the field of jigging and beneficiation of minerals, namely to a jigging machine and method to control movement of the jigging sieve, and may be used at beneficiation plants across coal and mineral industries.
BACKGROUND ART
The prior art includes various known designs of jigging machines and methods to control movement of their jigging sieve.
So, for example, a known movable sieve jig design is described in [Handbook of ore beneficiation. Basic processes. M.: Nedra, 1983, p. 54. — [Electronic resource], — Available at: https://libarch.nmu.org.ua/handle/GenofondUA/34706]. The sieve is driven by a mechanical drive through a crank mechanism.
Patent document UA17985 discloses the design of a jigging machine that comprises a body, a movable box with an inclined movable sieve, a box drive, an unloading section to discharge separation products and unloaders [patent of Ukraine No. 17985 (U), IPC (2006.01) B03B5/18, published on 16.10.2006 in Bulletin No. 10/2006].
Patent document UA41975 discloses the design of a movable sieve jigging machine that comprises a body, a movable sieve equipped with pneumatic actuators, which are interconnected by common stabilising shafts mounted in bearing units by means of rotating rods. The common stabilising shafts with bearing units are located on the outer sides of pneumatic drives and are connected to them by rotating rods, and the bearing units with shafts are
separated from the machine body and fixed on stationary surfaces [patent of Ukraine No. 41975 (U), IPC (2009) B03B5/00, published on 25.06.2009 in Bulletin No. 12/2009].
Neither of the above structures and sieve movement control methods provides means for operational adjustment of parameters that ensure optimisation of the jigging mode and separation of the jig bed into light (lower- density) and heavy (higher-density) fractions, and, accordingly, improved efficiency of the raw materials separation process. Besides, the known jigging machine mechanisms and related processes that take place in them during mineral beneficiation require excessive amount of utilities, such as electricity, raw materials to be separated, separating time and, accordingly, result in the increased jigging costs for processing of raw materials.
Thus, the object of the claimed invention is the development of such a jigging machine and method to control movement of the jigging sieve, which structure and sequence of stages, respectively, will ensure accomplishment of the technical result, which consists in improving the separation efficiency, enabling separation of raw materials of different composition, reducing the separation time and cutting down utility costs of the enterprise.
DISCLOSURE OF THE INVENTION
The objective has been solved through the development of a jigging machine comprising a movable sieve and a sieve drive system, where the sieve drive system enables setting the sieve movement speed and sieve acceleration separately for the compaction and loosening stages of the jigging cycle.
Besides, the objective has been solved through the development of method for controlling the jigging machine sieve movement with the help of a drive system, where the sieve drive system enables setting the sieve movement
speed and sieve acceleration separately for the compaction and loosening stages of the jigging cycle.
Thus, the claimed inventions are characterised by ensuring the possibility to set different speed and acceleration values for discrete movements of the sieve both in upward and downward directions, i.e. values being the main factors, which influence the efficiency of the raw material separation process. The sieve speed and acceleration can change dozens of times per minute. It is obvious that gaining control over these values allows organising pauses at any time of the sieve movement cycle, thus creating jigging cycles of any complexity and, accordingly, controlling operating regimes of the jigging machine. This, in turn, allows setting operating regimes of the jigging machine depending on the specific mineral to be separated, making the jigging machine practically universal in terms of composition of raw materials to be processed. Selection of the optimal operating regime, in turn, allows reducing the separation time and, accordingly, reducing consumption of water used for separation.
Most generally, the sieve drive system comprises a servo drive, which is composed of a gearbox with input and through shafts, a motor mounted on the input shaft of the gearbox, and feedback sensors mounted on the through shaft of the gearbox; at least two eccentric rods, which are mounted symmetrically on the gearbox through shaft on both its sides; a linkage supporting the sieve, which is mounted on free ends of the eccentric rods; and control system for the servomechanism.
Also, generally, the linkage comprises two mirrored rods on both sides of the through shaft, which are parallel to each other and to the through shaft; two levers, each having one end rotatably mounted on the free end of the corresponding eccentric cam, and the other end attached to the above-mentioned
rod; and two mirror-symmetric levers, each having one end mounted on the above-mentioned rods, and the other end attached to the sieve.
It should be noted that within the scope of this application, the sieve is understood as a structure that, in fact, comprises a sieve itself and a box surrounding the sieve. So, the lever ends are generally fixed to the sieve box.
Besides, generally, control system for the servomechanism comprises a driver connected with feedback sensors and a driver controller, where the driver controller is capable of generating control signals for the through shaft based on the received commands regarding the operating regime of the servo drive and sending them to the driver, and the driver is capable of controlling the motor based on the control signals received from the controller and data received from the sensors,
Accordingly, the claimed method is characterised by the use of the said jigging machine components.
Thus, the sieve drive system implements a complex process, ensuring accurate and highly efficient positioning of the sieve, i.e. its movement according to the specified operating regimes of the jigging machine. The servomotor allows converting rotary motion of a pair of eccentric cams to linear motion, which is then transferred to the linkage. The said linkage comprises minor-symmetric levers, and such arrangement allows compensating for their arc-shaped movement and ensures that the movable sieve stays horizontally while travelling in vertical direction.

The claimed invention functions as follows.
The sieve movement control process includes stages, when commands regarding the operation regime of the servo drive are given to controller 3 (an operator enters the operating regime of jigging machine 1). The said commands may be adjusted by controller 3 or other automatic systems such as CNC (computer numerical control). Then, based on the received commands, signals to control movement of through shaft 6 are generated and transmitted to the driver using controller 3. Control over motor 2 of the servo drive is carried out based on the control signals received from controller 3 using the driver, data from
feedback sensors installed on the gearbox through shaft 6 are transmitted to the driver, and control commands for motor 2 of the servo drive are corrected based on the data received from feedback sensors and control signals for through shaft 6 using the driver. The servomotor starts rotating according to the received commands and converts electrical energy into mechanical motion. During the rotational motion, the servomotor continuously sends data from feedback sensors regarding the current motor position and speed back to the driver. This data is used for correction and control, ensuring attainment of the required technical result.
Thus, such a jigging machine and method to control movement of the jigging sieve, which structure and sequence of stages ensure accomplishment of the technical result, which consists in improving the separation efficiency, enabling separation of raw materials with different composition, reducing the separation time and saving in the organisation’s material resources consumption have been developed.
