The feeding mechanism is used to connect the hopper 1 and the mixing tank. It is mainly composed of a housing, a feeding pipe 2, a fan and a filter screen 20. An air outlet 17 is arranged on the top of the housing. The middle position of the housing is divided into upper and lower parts by the filter screen 20. Part, the upper half is provided with a fan, the fan includes No. 2 motor 16 and fan blade 19, the lower half is used for feeding, one side is provided with a feed port, 2, the bottom is provided with a discharge port 21, and the feed port 22 is connected with the hopper 1 through the feed pipe 2, and the discharge port 21 is connected to the top of the mixing bucket and extends into the mixing bucket.

The mixing barrel is divided into upper and lower half-cylindrical barrel covers, the lower barrel cover 31 is fixed on the base 11 by a bracket, the upper barrel cover 28 and the lower barrel cover 31 are fixed by a double-ended screw 8, and the lower barrel cover 31 is fixed. The bracket is divided into two parts, left and right, which are respectively arranged at both ends of the mixing bucket, wherein the left bracket 31 is connected to the mixing bucket through rolling bearings 12, and the right bracket supports the mixing bucket through the support rods 10 and semicircular supporting rods 9 on both sides. The bottom of the right end, and the support rods 10 on both sides realize the lifting of the right support through hydraulic cylinders.

A stirring shaft is arranged at the central axis of the cylindrical mixing barrel, and a stirring blade 27 is arranged on the stirring shaft, and a heating wire is densely and evenly wound on the stirring blade 27. The stirring shaft is divided into an inner shaft and an outer shaft, and the outer shaft is hollow. The inner shaft is inserted inside the outer shaft, and the two are connected by positioning pins. The two ends of the inner shaft are connected to the mixing bucket, and several water outlet holes are evenly arranged on the surface of the outer shaft. The water tank and the cavity between the outer shaft and the built-in are connected by water pipes. , water is sprinkled into the mixing barrel through the outlet hole on the surface of the outer shaft. One end of the stirring shaft connects the No. 1 motor 14 that is positioned at the bottom of the mixing barrel by the belt 5, which can drive the stirring shaft to rotate, and the side barrel cover 29 on the right support of the mixing barrel is provided with an openable cover plate 30 on the outlet.

The device is also equipped with a control system, the control system adopts Siemens s7-200PLC, the signal input end of the control system is connected to the pressure sensor, and the signal output end is connected to the water tank motor, which is used to control the water volume of the water tank.

In actual use, at first the double-ended screw rod 8 is manually unscrewed to separate the upper and lower barrel lids, so as to prevent the inner blades from scratching when stirring. Then, pour the feed into the hopper 1, turn on the power button, the pressure sensor under the hopper 1 starts to record the weight of the feed, and at the same time transmit the data into the control system, the control system obtains the amount of water required for stirring through the internal program, and controls The water tank starts to take in water, and at the same time, the required medicine is dropped into the water tank 3 .

After the feed and medicine are all placed, the power is turned on, the No. 2 motor 16 in the feeder 7 is started, and the fan blade 19 that starts to drive the fan reverses, and the bottom of the filter screen 20 forms a negative pressure layer, and the feed is passed through the feed pipe 2, from The feeding port 22 is sucked into the feeder 7, and at the same time, the feed falls into the mixing barrel due to gravity, and the automatic feeding of the feed is completed.

After the feed enters the mixing chamber, the No. 1 motor 14 starts, and the belt 5 connected to it drives the stirring inner shaft 23 to rotate, because the stirring inner shaft 23 and the spiral stirring outer shaft 26 are connected by threads, and there are positioning pins 24 is fixed, and both start to rotate under the drive of No. 1 motor 14 simultaneously, thereby drive agitating blade to rotate, and feed is stirred.

At the same time, when the feed starts to stir, the sprinkler system starts to work, and the water added with medicine in the water tank 3, driven by the water pump, enters the gap between the inner shaft and the outer shaft from the water tank 3 through the water pipe 4, And spray out through the outlet hole on the spiral stirring outer shaft 26 to achieve the purpose of fully mixing the feed and the medicine. After stirring for a period of time, after the medicine and the feed are mixed evenly, the electric heating wire on the stirring blade 25 starts to heat, and the moisture inside the feed begins to Drying, so that the combination of medicine and feed is better.

After finishing stirring and heating and drying, it enters the discharge stage. The upper part of the left support 13 is provided with a rolling bearing 12, and the left end can rotate freely. At this time, the hydraulic cylinder at the right end is activated, and the support rod 10 of the right support is lowered. A height difference is formed at the two ends, and the discharge can be realized by manually opening the discharge port cover plate 30 . In order to prevent any surplus in the mixing bin, stir the interior again to discharge the remaining feed.

The present invention considers that the equipment needs to be cleaned after long-term use, and the cleaning function is specially designed. It is only necessary to tighten the double-headed screw 8 to combine the upper and lower barrel covers, start the second motor 14 to drive the stirring shaft to clean the inner wall, and start the spray device at the same time to clean the inner wall. The inner wall is flushed, and after the hydraulic cylinder is lowered, the residue is discharged with the water flow.

Considering that the internal structure of the equipment is complex and inconvenient for maintenance, the present invention designs a set of procedures for later maintenance. It only needs to remove the detachable right cover 29, and then pull out the positioning pin 24. Since the stirring inner shaft and the spiral stirring outer The shaft has threads to match, only need to start the No. 2 motor 14 to drive the stirring inner shaft, and the spiral stirring outer shaft can be turned out automatically, so as to achieve the purpose of convenient maintenance.
