During, the first blind hole and pick that the hydraulic system of coal-winning machine is arranged to pick intrinsic silicon overlap internal the second blind hole arranged
Interior injection low pressure oil, now the first oil pressure sensor and the second oil pressure sensor detect that pressure signal is fixing more than zero
Value, when pick matrix and pick set may wear at the first set blind hole and/or the second blind hole, low pressure oil is revealed, and pressure disappears
Losing, the first oil pressure sensor and/or the second oil pressure sensor are detected the signal that pressure is zero, are mined by data signal alignment
The control system of machine sends pick matrix and/or the pick set signal that puts in place of abrasion, and at this moment staff can promptly and accurately
Find pick matrix and the state of wear of pick set and change pick matrix and pick set, it is to avoid winning machine cutting part is also damaged
Bad.
Tooth head thread is connected in the mounting groove of pick matrix, and fixing with pick matrix by the way of soldering is connected,
Tooth head so can be avoided to be thrown out of after a period of operation come off, the first straight operation of tooth can be made to the bottommost of mounting groove.
On the exposed exposed surface outside pick matrix of surface, centring ring surface and tooth head outside pick overlaps of pick matrix
It is coated with diamond wear proof layer, the most fully extends this utility model service life in operation process.
In sum, this utility model simple in construction, easily operated monitoring, can discovery pick matrix promptly and accurately and
The state of wear of pick set, it is to avoid the abnormal damage of winning machine cutting part, the most fully extends the service life of each operation part,
Make production operation to be carried out continuously, reduce production cost.
