Description

Technical Field

[0001] This utility model relates to the field of drying devices, and in particular to a pig manure drying device for ecological pig farming. Background Technology

[0002] With the development of modern animal husbandry, the discharge of livestock waste such as pig manure is increasing day by day, becoming one of the important sources of environmental pollution. In particular, agricultural non-point source pollution and the deterioration of the ecological environment of livestock farming are becoming increasingly prominent, and effective measures need to be taken to solve them. The research and development and application of pig manure drying equipment is a response to this environmental protection demand. Through technical means, it realizes the harmless treatment and resource utilization of pig manure, reduces environmental pollution, and protects the ecological environment.

[0003] Existing pig manure drying devices for ecological pig farming typically use a drum type, where pig manure is tumbled and transported inside the drum by an auger shaft for drying, and then output from the tail of the drum to a material bag or storage frame. Some pig manure drying devices also use iron parts for heat conduction, where the pig manure is placed on the iron parts or on the drum to evaporate the internal moisture of the pig manure.

[0004] On the one hand, existing drum-type drying devices typically use a fixed-length auger shaft, which can only adjust the drying time of pig manure inside the drum by adjusting the rotation speed. It is impossible to extend the drying time of pig manure inside the drum according to the moisture content. On the other hand, the existing method of heat conduction by iron parts results in pig manure easily sticking to the iron parts due to rapid evaporation, which cannot be removed, leading to device blockage. Moreover, the efficiency of drying by relying solely on heat conduction by iron parts is low. Therefore, an ecological pig manure drying device for pig farming is proposed to solve the above problems. Utility Model Content

The groove frame 3 is configured as a double-groove through groove, and a heat-conducting pipe 11 is installed on the inner wall to keep the iron parts of the inner wall of the groove frame 3 at a high temperature, achieving a heat-conducting drying effect. A tank 4 is fixedly connected to the top of the outer wall of the groove frame 3. The tank 4 is a drying chamber where pig manure is repeatedly tumbled by a stirring plate 9, ensuring even heating and better evaporation and drying effects. A feed inlet 5 is fixedly connected to the top of the outer wall of the tank 4, allowing external manual or feeding machine dumping of pig manure into the tank 4 for drying. A motor 6 is fixedly connected to the top of the outer wall of the tank 4. The motor 6 is existing technology and will not be described in detail; it is used to drive the stirring plate. The mixing plate 9 repeatedly tumbles the pig manure for drying. The output end of the motor 6 is connected to the stirring rod 7 via an opening and closing assembly. The stirring rod 7 is used to change the opening and closing state of the bottom plate 16 by rotating the motor 6 in both directions. The top of the outer wall of the stirring rod 7 is provided with a sliding groove 8, which is used to engage the sliding rod 15 to keep the stirring rod 7 rotating. The outer wall of the stirring rod 7 is fixedly connected to the stirring plate 9, which is set as an auger shaft type. It is used to make the pig manure quickly fed or repeatedly lifted and tumbled by rotating the motor 6 in both directions. The bottom of the outer wall of the stirring plate 9 is fixedly connected to the telescopic plate 10, which is used to open or close the bottom plate 16 via the opening and closing assembly. The outer wall of the output shaft of the motor 6 passes through and is slidably connected to the top inner wall of the tank 4. The inner wall of the stirring rod 7 is slidably connected to the outer wall of the rotating shaft 14. The outer wall of the stirring plate 9 is slidably connected to the inner wall of the tank 4. The outer wall of the telescopic plate 10 is slidably connected to the inner wall of the bottom plate 16.

[0033] Reference Figures 1-3 A heat-conducting pipe 11 is fixedly connected to the inner wall of the trough frame 3. The heat-conducting pipe 11 is existing technology and will not be described in detail. It is used to keep the inner wall of the trough frame 3 at a high temperature. The outer wall of the trough frame 3 is connected to the outer wall of the tank body 4 through the air duct 12. A fan 13 is set in the middle of the air duct 12. The fan 13 is existing technology and will not be described in detail. It is used to extract heat from the inner wall of the trough frame 3 and transport it to the inner wall of the tank body 4 through the air duct 12, so as to realize air drying and drying at the same time. One end of the air duct 12 passes through and is fixedly connected to the top of the outer wall of the tank body 4, and the other end of the air duct 12 passes through and is fixedly connected to the top of the outer wall of the trough frame 3.

[0034] Reference Figures 3-5The opening and closing assembly includes a rotating shaft 14, which is used to drive the stirring rod 7 to rotate via the motor 6. The top of the outer wall of the rotating shaft 14 is fixedly connected to the output shaft of the motor 6. A sliding rod 15 is fixedly connected to the top of the outer wall of the rotating shaft 14. The sliding rod 15 is used to engage with both sides of the sliding groove 8 to change the opening and closing state of the bottom plate 16 by rotating the rotating shaft 14 in both directions. The bottom plate 16 is fixedly connected to the bottom of the outer wall of the rotating shaft 14. The bottom plate 16 is set in a downward cone shape. A certain gap is left between the bottom plate 16 and the groove frame 3, which can be used as a scraper or crushing plate to crush larger pieces of pig manure, allowing the pig manure to fall freely downwards and avoid blockage. The top of the outer wall of the rotating shaft 14 is slidably connected to the top of the inner wall of the tank 4. The outer wall of the sliding rod 15 is slidably connected to the inner wall of the sliding groove 8. The end of the outer wall of the bottom plate 16 is slidably connected to the inner wall of the tank 4.

[0035] Working principle: When the pig manure has a high moisture content, the motor 6 is turned on and rotated counterclockwise. The motor 6 drives the rotating shaft 14 to rotate, which in turn drives the sliding rod 15 to the right side of the trough 8. The sliding rod 15 then drives the stirring plate 9 to rotate, which in turn drives the telescopic plate 10 to close the opening of the bottom plate 16, keeping the tank 4 in a sealed state for air drying. This extends the drying time of the pig manure. Then, the motor 6 is switched to rotate clockwise again, which drives the rotating shaft 14 to move the sliding rod 15 to the left side of the trough 8. The sliding rod 15 then drives the stirring plate 9 to rotate, which in turn drives the telescopic plate 10 to open the opening of the bottom plate 16, allowing the pig manure to fall freely and contact the trough frame 3 for secondary heat conduction and drying. The manure then falls from the trough frame 3 into the storage frame 2 for removal, improving the drying efficiency and quality.

[0036] When drying pig manure, the heat is generated by an external power source through the heat pipe 11, keeping the inner wall of the tank 4 and the trough frame 3 at a high temperature. Then, the fan 13 is turned on to extract heat from the inner wall of the trough frame 3 through the air pipe 12, and then the heat is transferred to the inner wall of the tank 4 through the air pipe 12. This makes the bottom of the tank 4 heat-conducting drying and the top hot air drying, achieving a high-efficiency drying effect and improving the drying quality.
