The invention relates to the technical field of live pig cleaning, and provides a live pig slaughtering and cleaning device which comprises a cleaning cabinet, and a push-pull frame is arranged on one side of the cleaning cabinet; according to the pig cleaning device, a worker limits and fixes a live pig through a second clamping
assembly, the live pig rotates during cleaning, a second supporting rotary drum drives a fourth air rod to rotate, the fourth air rod rotates, a fourth gear rotates and is engaged with a second annular rack, the fourth air rod starts to rotate, and the fourth air rod rotates to drive a cleaning disc and a second cleaning
brush to rotate; the cleaning disc drives a second cleaning cylinder to rotate through a clamping plate, the second cleaning cylinder and a second cleaning
brush rotate at the same time to
brush the front feet, and therefore the situation that the feet cannot be cleaned is avoided, after the front feet are cleaned, the front feet are taken out, a fourth air rod is started, the fourth air rod drives the cleaning disc to descend, and the fourth air rod continues to rotate; and
dirt on the second cleaning brush is thrown out, so that the situation that the
dirt is accumulated on the second cleaning brush to affect next cleaning is avoided.
