[0002] In the pig farming industry, supplementary feeding and early weaning of suckling pigs are a method commonly used by breeders. Whether suckling pigs can be weaned smoothly is the key to the success of the pig farming industry. With the increasing number of farmers, people have more and more ways to process pig feed. Using wheat to feed pigs makes the growth rate of pigs fast. The wheat extruder is a kind of equipment for processing extruded food. It processes wheat in daily life. Its main working principle is to convert mechanical energy into thermal energy. The heat generated by the rotation of the machine is used to squeeze the food to cook. The most obvious feature of the extruded food is that the volume becomes larger. The wheat is extruded and used to feed pigs.

[0003] However, when the current pig feed raw material puffing device is in use, as the barrel is heated, the air pressure inside the barrel increases. When the staff opens the sealed door due to improper operation, the raw materials are easily splashed, causing harm to the staff.

[0004] In view of the above problems, a pig feed raw material puffing device is proposed. Utility Model Content

A cleaning rod 15 is fixedly installed on one side of the piston 13. A connecting hole 14 is opened on the surface of the connecting box 7 and the expanded barrel 4. The connecting hole 14 is communicated with the interior of the expanded barrel 4, and the cleaning rod 15 is slidably connected inside the connecting hole 14. A limiting guide rod 22 is fixedly installed on the surface of the sliding rod 11, and a connecting plate 16 is fixedly installed on one end of the sliding rod 11. The connecting plate 16 is slidably connected on the surface of the limiting guide rod 22.

[0026] As the extruder 4 is heated, the feed material inside the extruder 4 is gradually expanded, thereby increasing the internal air pressure, causing the air pressure inside the extruder 4 to enter the inside of the connecting box 7 through the connecting hole 14, and then the air pressure pushes the piston 13, thereby causing the sliding rod 11 to move inside the connecting box 7, causing the connecting plate 16 to slide on the surface of the limiting guide rod 22, and squeezing the return spring 10, so that the air pressure inside the extruder 4 is discharged through the exhaust valve 6, thereby reducing the air pressure inside the extruder 4, and then the connecting plate 16 is reset by the elastic force of the return spring 10, and then the sliding rod 11 and the piston 13 are reset, and then the cleaning rod 15 enters the inside of the connecting hole 14, and then the impurities inside the connecting hole 14 are cleaned out, thereby preventing the feed material from accumulating inside the connecting hole 14 and causing the connecting hole 14 to be blocked, thereby improving the communication between the connecting box 7 and the extruder 4, and thereby reducing the difficulty of cleaning the connecting hole 14 later.

[0027] A second rack 21 is fixedly mounted on the connecting plate 16, a gear 20 is rotatably connected to one side of the connecting box 7, the gear 20 is meshingly connected to the second rack 21, two slideways 18 are provided on the surface of the connecting box 7, the interiors of the two slideways 18 are respectively slidably connected with moving blocks 12, blocking plates 9 are fixedly mounted on the two moving blocks 12, limiting rods 17 are fixedly mounted inside the two slideways 18, the surfaces of the two limiting rods 17 are respectively slidably connected to the interiors of the two moving blocks 12, a first rack 19 is fixedly mounted on the side of the blocking plate 9 close to the gear 20, and the first rack 19 is meshingly connected to the gear 20.

When the connecting plate 16 is reset, the blocking plate 9 will be reset, so that the blocking plate 9 will no longer block the sealing door 8, so that it is convenient to block the sealing door 8 when the pressure inside the puffing barrel 4 is high, and then the sealing door 8 can be opened only when the air pressure inside the puffing barrel 4 is discharged, so as to prevent the staff from opening the sealing door 8 due to misoperation, causing splashing of raw materials inside the puffing barrel 4, thereby reducing injuries to the staff, improving the protection of the staff, and preventing accidents.

[0029] Working principle:

[0030] As the puffing barrel 4 is heated, the feed raw materials inside the puffing barrel 4 are gradually puffed, thereby increasing the internal air pressure, causing the air pressure inside the puffing barrel 4 to enter the inside of the connecting box 7 through the connecting hole 14, and then the air pressure pushes the piston 13, thereby causing the sliding rod 11 to move inside the connecting box 7, causing the connecting plate 16 to slide on the surface of the limiting guide rod 22, and squeezing the reset spring 10, so that the air pressure inside the puffing barrel 4 is discharged through the exhaust valve 6, thereby reducing the air pressure inside the puffing barrel 4, and then the connecting plate 16 is reset by the elastic force of the reset spring 10, thereby resetting the sliding rod 11 and the piston 13, and then causing the cleaning rod 15 to enter the inside of the connecting hole 14, and then cleaning out the impurities inside the connecting hole 14.

[0031] When the connecting plate 16 moves, it will drive the second rack 21 to move, and then drive the gear 20 to rotate, and then move the first rack 19, so that the direction of movement of the first rack 19 is opposite to the direction of movement of the second rack 21, and then drive the blocking plate 9 and the two moving blocks 12 to move, so that the two moving blocks 12 slide inside the two slideways 18 and on the surfaces of the two limiting rods 17, so that the blocking plate 9 blocks the sealing door 8. When the connecting plate 16 is reset, the blocking plate 9 will be reset, so that the blocking plate 9 will no longer block the sealing door 8, so that it is convenient to block the sealing door 8 when the pressure inside the puffing barrel 4 is high, and the sealing door 8 can be opened only when the air pressure inside the puffing barrel 4 is discharged.
