Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, in particular to an expansion device for pig feed processing. Background Art

[0002] Extruded feed is a pellet feed processed by extrusion and puffing technology. The extruded pig feed not only promotes the growth of piglets, but also has good functions in regulating the digestive physiological function of piglets and controlling diarrhea. The processing principle of extruded feed is that after the feed is squeezed out of the die hole of the extruder under great pressure, it suddenly leaves the body and enters the atmosphere, causing the temperature and pressure to drop sharply, causing the water in the feed to evaporate quickly and the volume of the feed to expand rapidly, thus obtaining extruded feed. Extruded feed has good palatability, high digestibility, and varied appearance, and can be made into floating or sinking feed. In the process of processing extruded pig feed, it is necessary to manually feed the raw materials into the extruder, which has high labor costs, and the feed amount and feed speed are difficult to control, which can easily cause the extruder to be blocked, affecting the processing efficiency.

[0018] like Figures 1 to 3 As shown, the puffing device for pig feed processing of the utility model includes an puffing machine 12 fixed on a bracket 10 and provided with a feed hopper 11 on the top, and also includes a crank 21, the lower surface of the crank 21 is inclined and the end is rotatably connected to the upper end of a swing shaft 22, the lower end of the swing shaft 22 is fixed to a swing plate 23, the swing plate 23 is arranged in a discharge port 25 of a storage hopper 24, and the storage hopper 24 is fixedly connected to the feed hopper 11; the swing shaft 22 is rotatably connected to a guide rod 26 and is vertically arranged, and the guide rod 26 slides up and down along the bracket 10.

[0019] The utility model drives the swing shaft 22 to rotate by the crank 21, and at the same time, the guide rod 26 on the swing shaft 22 slides up and down along the bracket 10 to limit the rotation of the swing shaft 22, so that the swing shaft 22 drives the swing plate 23 to swing circumferentially, that is, to perform continuous nutating motion, so that the edge of the swing plate 23 alternately covers and opens the discharge port 25 of the storage hopper 24, so that the storage hopper 24 can intermittently feed the feed hopper 11 and the extruder 12, thereby reducing labor costs, making it easy to control the feed amount and feed speed, and avoiding clogging of the extruder 12 and affecting the processing efficiency.

[0020] Among them, a driving motor is provided at one end of the extruder 12, and the auger is driven to rotate through a rotating shaft. A heating tube is provided inside the other end of the extruder 12, and a discharge port is provided. The structure of the extruder 12 is prior art and is not described here.

[0021] Preferably, a motor 27 is fixed on the bracket 10 , the output shaft of the motor 27 is fixed to the upper surface of one end of the crank 21 , and the lower surface of the other end of the crank 21 is rotatably connected to the upper end of the swing shaft 22 .

[0022] Preferably, the lower surface of the crank 21 is tilted from top to bottom and from close to to far away from the output shaft of the motor 27 .

[0023] Preferably, the center of the wobble plate 23 is located on the extension line of the output shaft axis of the motor 27 .
