The executive component comprises an electromagnetic block 4 and a magnet, the magnet is fixedly connected to one end, far away from the spring plate 17, of the sliding plate 5, the electromagnetic block 4 is fixedly connected to the base 13, the electromagnetic block 4 and the magnet are arranged just oppositely, and the electromagnetic block 4 is electrically connected with the coil 21 through a wire.

The free end of the shift lever 26 is also fixedly connected with an elastic head 27.

When the central shaft is driven by the water flow blade 16 to rotate, the coil 21 inside the central shaft is driven to rotate, the coil 21 cuts the magnetic induction line inside the magnet 22 to form current, the current flows onto the resistance screw rod 24 and the slip sheet 25 along with the lead wire, at the moment, the second belt wheel 14 rotates along with the central shaft, the shift rod 26 is continuously driven to flip the slip sheet 25, so that the slip sheet 25 repeatedly moves upwards, specifically, when the shift rod 26 rotates one circle along with the second belt wheel 14, the slip sheet 25 is driven to move upwards along the resistance screw rod 24 once, when the slip sheet 25 moves to the uppermost position of the resistance screw rod 24, the resistance screw rod 24 fully covers the resistance contact loop, the current passing through the electromagnetic block 4 is small, so that the magnetism of the electromagnetic block 4 is small, the sliding plate 5 is relatively close to the electromagnetic block 4, and when the slip sheet 25 moves away on the shift rod 26, the slip sheet falls behind along with the gravity, the resistance screw rod 24 is a zero resistance access loop, the current in the electromagnetic block 4 is larger at the moment, the electromagnetic block 4 and the magnet repel each other, and the falling time of the sliding sheet 25 is shorter than the rising time, so that the sliding plate 5 can be bounced for a certain distance by virtue of the magnetic force in a short time, the distance of relative motion between the sliding plate 5 and the ram 2 can be increased when the sliding plate 5 falls, and the ram 2 can lift the cowhide more easily.

Particularly, in the twinkling of an eye that launches, can shorten the time that the cow hide glides under the effect of friction power, and then can improve the speed that the relative ram 2 of control cow hide carries out the removal, improved the efficiency that ram 2 picked up the cow hide.

The effect of elastic head 27 then can be so that driving lever 26 when contacting with gleitbretter 25, can exert a pressure to gleitbretter 25, make gleitbretter 25 can take place the electrical contact with resistance screw 24 under this pressure, thereby the current regulation ability of resistance screw 24 has been guaranteed, and when elastic head 27 kept away from gleitbretter 25, there is the clearance between gleitbretter 25 and the resistance screw 24, so can fall fast, reach the purpose of the difference of gleitbretter 25 vertical movement speed, and then realize the purpose of ejecting slide 5.
