Therefore, in windy weather, the opened second sealing plate and the first sealing plate generate large wind resistance, and the second sealing plate and the first sealing plate are easily separated from the pig house due to the strong wind, resulting in damage to the pig house. In addition, the sunshade 3 can be opened on sunny days to illuminate the interior of the pig house. At the same time, the lighting effect inside the pig house can be adjusted by controlling the moving stroke of the active support rod 4, and the sunshade 3 can be closed on rainy days to keep out rain. It is suitable for a variety of weather conditions and improves practicality.

[0032] like Figures 2 to 6 As shown, the adjusting mechanism 5 includes: first moving blocks 6 are fixedly connected to both sides of the bottom of the active support rod 4, and threaded blocks 7 are fixedly connected to the adjacent sides of the two first moving blocks 6. Screws 8 are threadedly connected to the inside of the threaded blocks 7, and both ends of the screws 8 are rotatably connected to the fixed plate 2 respectively; two sliding rods 9 are slidably connected to the inside of the first moving block 6, and both ends of the sliding rods 9 are fixedly connected to the fixed plate 2; a power mechanism 10 for controlling the two screws 8 to rotate synchronously in the opposite direction is provided on one side of one of the fixed plates 2. The user controls the screws 8 on both sides to rotate in the opposite direction through the power mechanism 10. The screw 8 drives the two threaded blocks 7 to move in the same direction while rotating, and the threaded block 7 drives the first moving block 6 while moving.

[0034] like Figures 1 to 6 As shown, a plurality of driven support rods 14 are arranged on one side of the active support rod 4, and the driven support rods 14 are fixedly connected to the awning 3, and second moving blocks 15 are fixedly connected to both sides of the bottom of the driven support rod 14, and the second moving blocks 15 are slidably connected to the slide bar 9. When the awning 3 is opened, the active support rod 4 pushes the driven support rod 14 in turn, and the driven support rod 14 slides on the surface of the slide bar 9 through the second moving blocks 15. When the awning 3 is closed, the active support rod 4 pulls the driven support rod 14 in turn through the awning 3, which can prevent the middle section of the awning 3 from falling when the awning 3 is closed.

[0035] like Figures 1 to 6 As shown, a waterproof box 16 is provided near the dual-axis motor 11 of the fixed plate 2, and the first bevel gear 12, the second bevel gear 13 and the dual-axis motor 11 are all arranged inside the waterproof box 16, which can protect the dual-axis motor 11, the first bevel gear 12 and the second bevel gear 13 to prevent rain and dust from entering, which would cause oxidation, rusting and jamming of internal parts.

[0037] like Figure 6 As shown, the threads on the surfaces of the two screw rods 8 are arranged in opposite directions, so that the thread blocks on their surfaces can be pushed to move in the same direction while the two screw rods rotate in opposite directions.

[0038] like Figure 7 and Figure 8As shown, the separation mechanism 19 includes: a plurality of fixed rods 20 are evenly fixedly connected inside the pig house body 1, a groove plate 21 is provided at the bottom of the fixed rod 20, the groove plate 21 is fixedly connected to the pig house body 1, a filter cartridge 22 is fixedly connected inside the groove plate 21, a transmission shaft 23 is provided inside the filter cartridge 22, one end of the transmission shaft 23 is rotatably connected to the pig house body 1, the other end of the transmission shaft 23 passes through the connecting frame 24 and extends to the motor 25, the motor 25 is fixedly connected to the connecting frame 24, the connecting frame 24 is fixedly connected to the pig house body 1, the transmission shaft 23 is fixedly connected to the output end of the motor 25, the outer surface of the transmission shaft 23 located inside the groove plate 21 is fixedly connected with an auger blade 26; the outer surface of the transmission shaft 23 located outside the pig house body 1 is sleeved with an extrusion plate 27, a spring 28 is provided on one side of the extrusion plate 27, a threaded sleeve 29 is provided at one end of the spring 28 away from the extrusion plate 27, the threaded sleeve 29 is threadedly connected to the transmission shaft 23, and the pig house body 1 is away from the connecting frame A drain port 30 is provided on one side of the frame 24, and the excrement of the pig falls onto the trough plate 21 through the gap between the fixing rods 20. Due to the inclined surface setting of the trough plate 21, the excrement of the pig slides into the trough inside the trough plate 21, and then the motor 25 is started, and the output end of the motor 25 drives the transmission shaft 23. While the transmission shaft 23 rotates, it drives the auger blade 26 to rotate and transport the excrement. When the excrement is transported to the inside of the filter cartridge 22, the auger blade 26 cooperates with the extrusion plate 27 to squeeze the excrement, so that the moisture inside the excrement is separated through the filter cartridge 22, and the separated water is discharged to the outside of the pig house body 1 through the drain port 30. At the same time, the solid excrement squeezes and pushes the extrusion plate 27, and is discharged to the outside of the pig house body 1 through the gap between the extrusion plate 27 and the pig house body 1. The user can also rotate the threaded sleeve 29 to adjust the distance between the threaded sleeve 29 and the extrusion plate 27, thereby adjusting the hardness of the spring 28, thereby achieving the effect of adjusting the solid-liquid separation of the pig excrement.

[0039] Working principle: start the double-axis motor 11, the output ends on both sides of the double-axis motor 11 drive the first bevel gear 12, the first bevel gear 12 drives the second bevel gear 13, and the second bevel gear 13 drives the two screws 8 to rotate in the opposite direction at the same time, and the screw 8 drives the two threaded blocks 7 to move in the same direction while rotating, and the threaded block 7 drives the first moving block 6 while moving, and the first moving block 6 drives the active support rod 4 while sliding on the surface of the slide rod 9, thereby controlling the active support rod 4 to move horizontally. When the awning 3 is opened, the active support rod 4 pushes the driven support rod 14 in turn, and the driven support rod 14 slides on the surface of the slide rod 9 through the second moving block 15. When the awning 3 is closed, the active support rod 4 pulls the driven support rod 14 in turn through the awning 3, which can prevent the awning 3 from being blocked when it is closed. If the middle section of the awning 3 falls, the user can control the opening and closing of the awning 3 by controlling the forward and reverse rotation of the dual-axis motor 11, and the opened awning 3 will not increase the overall wind resistance of the device in windy weather, which solves the problem that pig houses are generally set up in the open air. Therefore, in windy weather, the opened second sealing plate and the first sealing plate generate large wind resistance, which may easily cause the second sealing plate and the first sealing plate to separate from the pig house due to strong winds, resulting in damage to the pig house. In addition, the awning 3 can be opened on sunny days to illuminate the interior of the pig house, and the lighting effect inside the pig house can be adjusted by controlling the moving stroke of the active support rod 4, and the awning 3 can be closed on rainy days to keep out rain. It is suitable for a variety of weather conditions and has improved practicality.

[0040] The excrement of the pig falls onto the trough plate 21 through the gap between the fixing rods 20. Due to the inclined surface setting of the trough plate 21, the excrement of the pig slides into the trough inside the trough plate 21, and then the motor 25 is started. The output end of the motor 25 drives the transmission shaft 23. The transmission shaft 23 rotates while driving the auger blades 26 to rotate and transport the excrement. When the excrement is transported to the inside of the filter cartridge 22, the auger blades 26 cooperate with the squeezing plate 27 to squeeze the excrement, so that the moisture inside the excrement is separated through the filter cartridge 22, and the separated water is discharged to the outside of the pig house body 1 through the drain port 30. At the same time, the solid excrement squeezes and pushes the squeezing plate 27, and is discharged to the outside of the pig house body 1 through the gap between the squeezing plate 27 and the pig house body 1. The user can also rotate the threaded sleeve 29 to adjust the distance between the threaded sleeve 29 and the squeezing plate 27, thereby adjusting the hardness of the spring 28, thereby achieving the effect of adjusting the solid-liquid separation of the pig excrement.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
