The gap adjustment algorithm by the hydraulic gap adjuster 65 is based on the operation of the hydraulic cylinder 67-2 of the hydraulic tension adjuster 67 and the operation of the gap adjustment hydraulic cylinder 65-4 - Adjustment of the gap by the forward or backward movement of the toggle plate (65-5) - After the adjustment of the gap is completed, the hydraulic tension adjuster (67) The pressure of the hydraulic cylinder 67-2 is filled.

The discharge conveyor 70 is provided so as to correspond to the outlet of the joining path 54 and the outlet of the jaw crusher 60 at one upper side, and is driven by the hydraulic motor to discharge the crushed material.

Meanwhile, a magnetic force sorter 80 may be installed on the discharge conveyor 70 for sorting the iron particles included in the pulverized material discharged along the discharge conveyor 70.

The magnetic force sorter 80 may be a variety of products such as a track type.

The load responsive control means is composed of a pressure sensitive control unit, a height responsive control unit, and a lump responsive control unit, each of which can be controlled as well as merge.

The pressure responsive control unit senses the pressure applied to the rotary shaft of the hydraulic motor for swinging the swing jaws 63 and controls the speed of the feeder 50 when the pressure is higher than a predetermined pressure based on the pressure value, The reference pressure (which depends on the size of the raw material of the crushing material and freely set by the operator's input) is stored through the memory, and the reference value is compared with the sensing value of the pressure sensor, And a controller for controlling the feeder 50 when the pressure is greater than the reference pressure.

The pressure sensor senses the in-line pressure of the hydraulic motor for driving the swing jaws.

In the pressure responsive control, if the sensed value is greater than the reference pressure, the speed of the feeder 50 is controlled to be decelerated, and the deceleration control is preferably performed in two or more stages. For example, if the reference pressure is set to 220 bar and the sensing value is higher than 220 bar, if the pressure of 220 bar or more is maintained for 1 second to 3 seconds, the speed of the feeder 50 is controlled to be 80% If the pressure is maintained for 4 to 6 seconds, the speed of the feeder 50 is reduced to 60% of the current speed. If the pressure of 220 bar or more is maintained for 7 seconds or more, the feeder 50 is stopped.

The reference pressure may be set in steps of 220 to 250 bar, 2 to 251 to 280 bar, and 3 to 281 to 300 bar. If the sensed value satisfies the first step range, Decelerates the speed of the feeder 50 at a speed of 80% and controls the speed of the feeder 50 to decelerate at a speed of 60% if the range of the second step is satisfied.

The height responsive control unit is a control based on the amount of the crushed raw material put into the jaw crusher 60, and includes a height sensor for detecting the height of the crushed raw material, and a comparison unit for comparing the sensed value sensed by the height sensor with the previously stored reference height And a controller for decelerating and controlling the speed of the feeder (50).

The height sensor is installed, for example, as an ultrasonic sensor at the top (inlet side) of the jaw crusher 60 so as to measure a 70% height point from the exit of the jaw crusher 60, for example.

The height responsive control can be either a one-step control or a multi-step control.

The first stage control is to decelerate the feeder 50 at a constant speed when the crushed raw material exceeds a certain height.

The multistage control is performed by controlling the speed of the feeder 50 corresponding to the multistage height sensor (for example, 80% deceleration, 60% deceleration, stop ).

The dross response control unit includes a deflector 90 disposed below the outlet of the jaw crusher 60 and colliding with the drop of the dross, a load cell sensing a load applied to the discharge pad 90, And a controller for stopping the feeder 50 or controlling the swing jaws 63 of the jaw crusher 60 in the reverse direction if the feeder 50 is not present for a predetermined period of time.

The discharge pad 90 is installed at an inclined lower portion of the exit of the jaw crusher 60 so as to guide the dropping material falling through the outlet of the jaw crusher 60 to the discharge conveyor 70, (For example, "0") and the controller outputs a value of " 0 " And controls the reverse rotation of the stop or swing jaws (63).

The discharge pad 90 is hinged to one side of the jaw crusher 60 and is connected to the angle regulating cylinder 91. The discharge pad 90 is installed to be angularly adjustable with respect to the exit of the jaw crusher 60, Is connected to the jaw crusher 60 and the discharge pad 90, respectively, and the angle of the discharge pad 90 is adjusted by the angle adjusting cylinder 91.

It is preferable that two or more of the above-described three kinds of parallel control are performed, rather than one of the pressure-sensitive control, the height-sensitive control and the lumi- nal-response control. For example, when the sensing pressure is higher than the reference pressure, If the pulverized material is not discharged during the deceleration control, the stop control of the feeder 50 or the reverse rotation control of the swing jaw 63 is performed, or the sensing pressure is higher than the reference pressure to decelerate the feeder 50 If the height of the crushed raw material becomes higher than the reference height, the feeder 50 is decelerated based on the decelerated speed from the initial speed to 80%.

4 is a view showing the installation position of the sensor applied to the load responsive control unit. The pressure sensor is installed on the inline side of the hydraulic motor of the swing jaws 63, and the height sensor is 100% from the lower end to the upper end It is installed at the top of the jaw crusher 60 without being installed at a height of 70% to detect the filling of the crushed raw material at the height of 70% from the exit, that is, to prevent breakage and malfunction, The load cell is installed in a fixture (bolt) for fixing the discharge pad 90.

The three types of the control are controlled so that the feeder 50 is restored to the normal state (initial setting speed) when the control condition described above is solved.

The number of cases using the three kinds of the above-mentioned three kinds of the sensitive control is various and can be practiced by those skilled in the art, so a detailed description will be omitted.

The operation of the mobile jaw crusher according to the present invention constructed as described above is as follows.

1. Instrument settings.

Start the engine and start crushing when the engine speed reaches, for example, 1800 rpm.

The speed of the feeder 50 is set in advance and this setting speed is recognized as 100%.

2. Input of raw stone (crushed raw material).

The feeder 50 is operated while the hopper 40 is standing on the upper side of the feeder 50 and the raw material for the crushing is put into the hopper 40.

The raw material for crushing is conveyed toward the jaw crusher 60 by the vibration of the feeder 50 and is introduced into the jaw crusher 60.

The crushed raw materials of various sizes are fed to the jaw crusher 60. The crushed raw materials of the crushed raw materials are sorted into the bottom portion through the clay sorting hole 51 and supplied to the jaw crusher 60, When the raw material for crushing is introduced into the jaw crusher 60, when the crushing raw material larger than the entrance of the safety net 66 and the jaw crusher 60 is inputted, the safety net 66 is lifted upwards, (60).

The gravel having passed through the gravel sorting hall (51) is discharged to the gravel discharge conveyor (53) or discharged to the discharge conveyor (70) according to the position of the switching damper (55).

3. Shredding.

The swing jaws (63) crush the crushing raw material which is put into the jaw crusher (60) while swinging.

4. Emissions.

The crushed material is dropped through the outlet of the jaw crusher 60 and discharged along the discharge conveyor 70.

The pressure sensor detects the pressure of the jaw crusher 60 and the height sensor detects the pressure of the jaw crusher 60 inserted into the jaw crusher 60. [ And the load cell senses the crushed material discharged from the jaw crusher 60.

For example, when the crushing pressure is high due to the high strength of the ore in the crushing process, the pressure value sensed by the pressure sensor will be high. The controller compares the reference pressure with the sensing pressure in real time. If the sensing pressure becomes higher than the reference pressure The speed of the feeder 50 is reduced. When the speed of the feeder 50 is reduced, the amount of the crushing raw material to be supplied to the jaw crusher 60 is reduced. As a result, the load of the jaw crusher 60 becomes small, so that the crushing raw material introduced into the crusher 60 can be crushed.

When the sensing pressure sensed by the pressure sensor through the crushing of the crushed raw material is lowered to the reference pressure, the feeder 50 is accelerated to the initial setting speed.

Further, for example, if the amount of the crushed raw material is greater than the crushing capacity of the jaw crusher 60 and the height sensor senses it, and the controller determines that the sensing height is higher than the reference height, the feeder 50 is decelerated . Accordingly, since the amount of the crushing material to be supplied to the jaw crusher 60 is reduced, the jaw crusher 60 can crush the crushing material put into the inside through a small load. When the crushing material inside the jaw crusher 60 is lowered below the reference height, the feeder 50 is accelerated to the initial setting speed.

On the other hand, the crushed material crushed in the jaw crusher 60 falls on the discharge pad 90 through the outlet, collides with the discharge pad 90, and is discharged to the discharge conveyor 70. The load cell of the discharge pad 90 outputs data having a constant value (a value different from that at the time of collision) upon collision of the crushing object. If the data is not output for a predetermined time, the jaw crusher 60 transmits It is judged that the crushing raw material can not be crushed and the feeder 50 is stopped or the swing jaws 63 are reversely rotated.

The stopper of the feeder 50 is output through a monitor or an alarm and the operator confirms the jaw crusher 60 with the naked eye and manually manipulates the swing jaw 60 to forcibly discharge the crushing material inside the jaw crusher 60 .

The reverse rotation control of the swing jaw 63 can be performed both automatically and manually and the swing jaw 63 is controlled to rotate counterclockwise or to open the gap with the fixed jaw 64 for a predetermined period of time, To be forcibly discharged.

The mobile jaw crusher of the present invention is configured such that an outlet gap adjusting means is provided to precisely and easily adjust the gap of the outlet of the jaw crusher (60).

The outlet gap adjusting means is composed of a pressure gauge of the swing jaw 63 and a distance gauge and a controller for measuring the distance of the swing jaw 63 from the backward direction (away from the fixed jaw 64).

The pressure gauge of the swing jaw 63 measures the pressure of the eccentric shaft for driving the swing jaws 63, the pressure of the swing jaws 63, and the like.

The outlet gap adjusting method using the outlet gap adjusting means is as follows.

The swing jaws 63 are moved toward the fixed jaws 64 and the pressure of the swing jaws 63 is increased through the pressure gauge of the swing jaws 63. [ The pressure of the hydraulic cylinder of the hydraulic gap regulator 65 increases as the swing jaws 63 come into contact with the fixed jaws 64 while monitoring the pressure of the swash plate 63 toward the fixed jaws 64. As a result, The swing jaw 63 is initialized to "0 ", and the swing jaw 63 is retracted from the swing jaw 63 by the exit gap. It is possible to check the backward distance of the swing jaw 63 through the distance gauge (through the monitor). When the swing jaw 63 is retracted by the exit gap, the backward movement of the swing jaw 63 is stopped automatically or manually .
