[0014] Step 1: Determine and set the start time

[0015] The determined feeding time for pigs is set in two time-controlled switches Ta and Tb.

[0016] Step 2: The railcar starts running

[0017] When the set time arrives, the time-controlled switch Ta or Tb automatically starts up and connects the coil of the travel contactor KMa or KMb, closing the normally open contact, the travel motor starts running, and the feeding car runs.

[0018] Step 3: Start cutting

[0019] When the feeding vehicle runs to the end of the trough, the contact of the feeding switch SQ3 or SQ4 at end a or b touches the corresponding contact block, closing the normally open terminal of the feeding switch SQ3 or SQ4 and connecting the coil of the feeding contactor KM3, causing the feeding motor to start rotating to feed.

[0020] Step 4: Mix wet materials and feed while walking

[0022] Step 5: Stop feeding and water

[0023] When the feeding car moves to the end of the trough at the other end of the pen, the contact of the stop switch SQ5 or SQ6 at the a or b end touches the corresponding contact block at the other end, so that the normally open SQ5-1 or SQ6-1 of the stop switch is closed. After the normally open is closed, the stop relay coil is energized and attracted, so that the normally closed contact k1-1 or K2-1 of the stop relay at the a or b end is disconnected, and the coil of the feeding contactor LM3 is de-energized. At the same time, the coil of the water pump contactor KM5 is also de-energized, the feeding motor and the water pump stop, and the feeding of the wet mixing material stops;

[0024] Step 6: Parking

[0025] After the feeding stops, the rail feeding car continues to move forward. When the contact of the travel switch SQa or SQb at the a or b end touches the corresponding touch block, the normally closed SQa-1 or SQb-1 of the travel switch is disconnected, the feeding car stops moving, and the time switch Ta or Tb automatically shuts down after the downtime. At this point, a stroke of wet material feeding is completed, and then, material and water are automatically added, waiting for the next start.

Step 2: The railcar starts running When the set time arrives, the time-controlled switch Ta or Tb automatically starts up and connects the coil of the travel contactor KMa or KMb, closing the normally open contact, the travel motor starts running, and the feeding car runs. Step 3: Start cutting When the feeding vehicle runs to the end of the trough, the contact of the feeding switch SQ3 or SQ4 at end a or b touches the corresponding contact block, closing the normally open terminal of the feeding switch SQ3 or SQ4 and connecting the coil of the feeding contactor KM3, causing the feeding motor to start rotating to feed.
