Below in conjunction with accompanying drawing and embodiment the utility model is further described.

The manure cleaner used in the present invention is a one-to-two structure shown in Figure 1 (two manure scrapers 4 are arranged on the traction rope 3), including a motor 1, four corner wheels 2, a traction rope 3 and two scrapers The manure board 4, the four corner wheels 2 are respectively set on the four corners through the corner wheel installation shaft 5, the traction rope 3 is connected to the rotating shaft of the motor 1 around the four corner wheels 2, and the two manure scrapers 4 are fixedly connected On the tow rope 3. The motor 1 rotates to drive the traction rope 3 to move, and the two manure scrapers 4 move thereupon to play the role of scraping chicken manure. The positive and negative rotation of the motor 1 reciprocates the two manure scrapers 4 .

As shown in FIG. 2 , the control device of the excrement cleaning machine of the present invention mainly includes three parts: a motion sensing device, a central micro-controller and a three-phase motor forward and reverse controller 6 . The three-phase motor forward and reverse controller 6 is an existing general-purpose device, electrically connected with the motor 1, and used to control the forward and reverse of the motor 1, and the three-phase motor forward and reverse controller 6 is connected with the micro-controller through the three-core cable 7 Device 8 is connected. The motion induction device is divided into two parts, the magnetic steel 10 and the Hall proximity switch 12.
