[0047] The main body 3 (composed of a left main body 310 and a right main body 320 that are set separately) is detachably connected to the base 20 and forms a suffocation chamber (composed of a first suffocation chamber 3a and a second suffocation chamber 3b that are set at intervals) between it and the base 20.

[0048] The top of the body 3 is equipped with an exhaust valve (composed of a first exhaust valve 31 and a second exhaust valve 32, which are used to exhaust the gas in the first or second asphyxiation chamber, respectively). The base 20 has a plurality of exhaust branches connected to the asphyxiation chamber and at least one air intake chamber connected to each exhaust branch. The air supply pipe is connected to the air intake chamber.

[0049] The machine body 3 has an movable opening 30 for the material rack 21 to move. When the material rack 21 slides, it can move out of the movable opening 30 or into the suffocation chamber. The machine body 3 is also slidably connected to a sealing plate 83. The sealing plate 83 can slide longitudinally (the side of the sealing plate 83 near the machine body is provided with a sealing layer to improve the sealing performance when closing the movable opening), thereby opening or closing the movable opening 30. Each material rack 21 can be controlled to maintain a first position or a second position respectively.

[0059] Chain 61 is connected between the sprockets 60 for transmission;

[0060] In this embodiment, any sprocket 60 can be controlled to rotate by the drive motor 62, which is supported by the motor base 63. It should be noted that in other embodiments, the drive structure can also adopt a pulley structure. Therefore, the use of a sprocket structure to control the rotation of the drive gear in this embodiment is not intended to limit the drive structure of this utility model to the only structure. As for the size of the sprocket and chain, this embodiment can be selected according to the actual situation, as long as it can ensure smooth control of the drive gear. Therefore, it will not be described in detail in this embodiment.

[0061] In this embodiment: the frame includes:

[0062] The arc-shaped base plate 70 is adapted to the arc-shaped surface of the support 201 and has a groove 700 that mates with the slide rail 40.

[0063] Side filter plates 71 are fixedly connected to the arc-shaped base plate 70 and are spaced apart;

[0064] The top filter plate 72 is fixedly connected between the side filter plates 71;

[0065] Among them, the rack 51 is installed on the arc-shaped base plate 70, and the arc-shaped base plate 70, the side filter plate 71 and the top filter plate 72 form a material cavity. One end of the material cavity is fixedly connected to the sealing plate 73, and the other end of the material cavity is hinged to the opening and closing plate.

[0066] In this embodiment, both the side filter plate and the top filter plate are provided with a number of filter holes to allow the gas in the asphyxiation chamber to enter the material chamber.

[0067] In this embodiment: the opening and closing plate includes:

[0068] The hinged base 750 is mounted on the arc-shaped base plate 70;

[0069] The plate 751 is rotatably connected to the hinge seat 750 via a rotating shaft 751a;

[0070] The plate 751 has several blind holes, and each blind hole is fitted with a limiting hook 753 by a limiting spring 752. The limiting hook 753 can cooperate with the filter holes of the top filter plate 72.

[0071] In this embodiment: a plurality of exhaust chambers 80 constituting exhaust branches are formed on the support body 201, and a plurality of exhaust holes 81 constituting the output end of the exhaust chambers 80 are formed on the arc-shaped surface of the support body 201.

[0072] At least two air intake chambers 82 are formed within the seat 200 and are connected to each exhaust chamber 80; each air intake chamber 82 can be supplied with air by one of the air supply pipes. In this embodiment, the first air supply pipe and the second air supply pipe are respectively connected to each air intake chamber 82.

[0073] refer to Figures 1-4 The principle of this embodiment is:

[0074] When the drive motor controls the sprocket to rotate clockwise, the drive gear on the left side of the support also rotates clockwise. Therefore, the material rack on the left side of the support moves from the first position to the second position, meaning it enters the confinement chamber through the opening. Meanwhile, the drive gear on the right side of the support is also controlled by the sprocket to rotate clockwise, thus driving the material rack on the right side of the support to move from the second position to the third position, meaning it exits the confinement chamber through the opening. Conversely, when the drive motor controls the sprocket to rotate counterclockwise, the material rack on the left side of the support leaves the confinement chamber, while the material rack on the right side enters. In this way, the two material racks can be simultaneously controlled to switch between different positions. When one material rack is inside the confinement chamber, the other material rack is outside the confinement chamber for loading.

[0075] When the material rack is in the asphyxiation chamber, the sealing plate is lowered to close the opening, and carbon dioxide gas is supplied into the asphyxiation chamber through the gas supply pipe. The gas enters the exhaust chamber from the air inlet chamber and exits the asphyxiation chamber through the exhaust hole on the support body. Initially, the exhaust valve on the top of the machine can be opened. In this way, when carbon dioxide gas enters the asphyxiation chamber, the gas in the asphyxiation chamber can be discharged through the exhaust valve. After a period of discharge, the exhaust valve is closed, so that the animal can be killed in the asphyxiation chamber.

[0076] After killing the animal, open the closing plate and the opening and closing plate on the material rack. In this position, the material rack in the second position has the material opening at the bottom, and the animal in the material cavity can be discharged from the material opening due to gravity. After unloading, the material rack is switched to the first position by the drive structure. At this time, the material opening of the material cavity is at the top. When feeding, the animal slides to the bottom of the material cavity due to gravity, which makes it easier to feed into the material cavity.

[0077] It is worth mentioning that when disassembling the machine body, if the left machine body is to be disassembled, the material rack on the left side of the control support is moved into the suffocation chamber, thereby disassembling the left machine body. Similarly, the right machine body can also be disassembled.

[0078] Example 2 differs from Example 1 in that:

[0079] like Figure 5 As shown, in this embodiment, a feed hopper 90 is installed on the machine body 3;

[0080] After the material rack leaves the suffocation chamber from the movable port 30, one end of the material rack can abut against the output end of the feed hopper 90.

[0081] refer to Figure 5 To facilitate feeding, this embodiment is equipped with a feeding hopper on the machine body. When feeding the material rack, animals can be poured into the material rack through the feeding hopper, thereby improving the feeding efficiency.

[0082] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
