The present invention relates to the technical field of mechanical equipment, in particular to a defeathering device used for chicken farms and convenient for chicken feather collection. The device comprises a shell, an outer cylinder, a cleaning device, a defeathering device and a compression device; the upper end face of the shell is fixedly connected to the outer cylinder, and the defeatheringdevice is arranged inside the outer cylinder; the upper end face of the shell is fixedly connected to the defeathering device; the compression device is arranged inside the shell; the right end face of the shell is fixedly connected to the cleaning device; and a defeathering machine is arranged below the outer cylinder. In the invention, a water tank, an electric heating wire water pump and waterpipes are arranged. If the defeathering effect is poor due to a temperature reason, the water in the water tank can be heated by electric heating wires, then the water pump pumps out the hot water tocarry out heating and defeathering on chickens through the water pipes. The device ensures the defeathering effect, saves a great deal of time, improves the efficiency, saves the cost, has good practical benefit, and is worthy of popularization and use.
