[0009] Preferably, the extended end of the first drive mechanism is engaged with two sets of chains, and the two sets of chains are respectively engaged with one end of the octagonal frame. The outer side of the chains is provided with chain guards that are fixedly connected to the liquid storage tank.

[0010] Preferably, the primary separation mechanism has a discharge trough fixedly connected to the base at one end of the discharge port, and the discharge trough has an inlet. Multiple secondary separation mechanisms fixedly connected to the base are located at the bottom of the discharge trough. Each secondary separation mechanism includes a sealed chamber sealed to the inlet. A fixed frame is fixedly connected to one side of the sealed chamber. A screen is fixedly connected to the middle of the fixed frame. A three-sided frame is fixedly connected to one end of the fixed frame. A shaft is rotatably connected to the middle of the three-sided frame. An adjusting plate is fixedly connected to one end of the shaft. A spring is fixedly connected to the adjusting plate near the fixed frame. The spring is nested outside the shaft. A pressing plate is fixedly connected to one end of the spring. The pressing plate abuts against the fixed frame. A spiral rod is rotatably connected inside the sealed chamber and the screen. One end of the spiral rod is fixedly connected to the shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model employs multi-stage separation technology to separate duck manure. The primary separation mechanism passes easily separable water through a screen to separate the manure. The separated manure is then transferred to a secondary separation mechanism where remaining, less easily separated water is thoroughly squeezed out, ultimately yielding dry duck manure. Using this multi-stage separation technology results in lower moisture content, more thorough separation, and higher efficiency, meeting the needs of large-scale factory applications.

[0017] 2. This utility model uses a high-pressure blower instead of a water gun to clean the screen during operation, preventing blockage and avoiding the generation of a large amount of polluted water, thus reducing the impact on the environment and making it more environmentally friendly.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figures 1 to 9 As shown, a multi-stage dry and wet duck manure separation device includes a base 1, a primary separation mechanism 2 and a secondary separation mechanism 3. A liquid storage tank 101 is fixedly connected to one side of the base 1, and a control box 4 is fixedly connected to one side of the liquid storage tank 101 for controlling all electrical equipment in this utility model. On the other side, a high-pressure blower 5 and a first drive mechanism 6 are fixedly connected. A double arc-shaped baffle 1015 is fixedly connected to the upper part of the liquid storage tank 101. The height between the two arcs of the double arc baffle 1015 is lower than the feed inlet. Each side of the bottom of the double arc baffle 1015 has a second liquid outlet 1014. Inside the liquid storage tank 101, on the same side as the second liquid outlet 1014, there are two sets of first liquid inlets 1012 and second liquid inlets 1013. The second liquid outlet 1014 is located outside the liquid storage tank 101 and is fixedly connected to a cleaning pipe 9. One end of the cleaning pipe 9 is fixedly connected to the first liquid inlet 1012. A valve 901 is fixedly connected in the middle of the cleaning pipe 9. Two bearing seats 109 are fixedly connected to both sides of the long side of the liquid storage tank 101. The upper end of the double arc baffle 1015 is provided with two primary separation mechanisms 2 that are rotatably connected to the bearing seats 109, which facilitates the rotation of the primary separation mechanisms 2 and reduces friction.

[0031] like Figure 8 and Figure 9 As shown, the primary separation mechanism 2 includes an octagonal frame 201. The outer diameter of the octagonal frame 201 is the same as the inner diameter of the double-arc baffle 1015. This allows each face of the octagonal frame 201 to be divided, compressing the duck manure. A spiral plate 204 is fixedly connected to the middle of the octagonal frame 201. One end of the spiral plate 204 is fixedly connected to the outer edge of the octagonal frame 201, and the other end is open. One end of the octagonal frame 201 is also open, and a liquid outlet 202 is fixedly connected to the opening, communicating with the interior of the spiral plate 204. A screen 203 is fixedly connected to the eight sides of the outer edge of the octagonal frame 201. The separated water passes through the screen 203 and falls onto the spiral plate 204, flowing out through the liquid outlet 202.

[0032] One end of the liquid outlet 3 202 is fixedly connected to a transfer pipe 8, one end of which is fixedly connected to the liquid inlet 2 1013. The transfer pipe 8 is also fixedly connected to the storage tank 101. The air outlet of the high-pressure blower 5 is sealed with an air outlet pipe 501. The air outlet pipe 501 is divided into two branches, which are fixedly connected to the discharge end of the double arc-shaped baffle 1015. The air outlet pipe 501 has multiple air outlet holes 502 inside the double arc-shaped baffle 1015. The air outlet holes 502 are directly facing the screen 1 203 to blow the duck manure off the screen 1 203 and prevent the duck manure from clogging the screen 1 203.

[0033] Two sets of chains 601 are connected to the gears on the extended end of the first drive mechanism 6. Each set of chains 601 is connected to a gear on one end of an octagonal frame 201. The advantage of using chains is that the driving force from the first drive mechanism 6 can be transmitted to the two octagonal frames 201. This controls the rotation of the primary separation mechanism 2 to separate and compress the duck manure. A chain guard plate 602, fixedly connected to the liquid storage tank 101, is provided on the outer side of the chain 601.

[0034] like Figure 6As shown, the primary separation mechanism 2 has a discharge trough 105 fixedly connected to the base 1 at one end of its discharge port. The discharge trough 105 has a feed inlet 1051. Multiple sets of secondary separation mechanisms 3 fixedly connected to the base 1 are located at the bottom of the discharge trough 105. Each secondary separation mechanism 3 includes a sealed chamber 301 sealed to the feed inlet 1051. A fixed frame 304 is fixedly connected to one side of the sealed chamber 301. A screen 305 is fixedly connected to the middle of the fixed frame 304. A three-sided frame 309 is fixedly connected to one end of the fixed frame 304. A shaft 308 is rotatably connected to the middle of the three-sided frame 309. An adjusting plate 310 is fixedly connected to one end of shaft 308. A spring 307 is fixedly connected to the end of adjusting plate 310 near the fixed frame 304. The spring 307 is nested on the outside of shaft 308. A pressing plate 306 is fixedly connected to one end of spring 307. The pressing plate 306 abuts against the fixed frame 304. A spiral rod 303 is rotatably connected inside the closed chamber 301 and the second screen 305. One end of the spiral rod 303 is fixedly connected to shaft 308, and the other end of the spiral rod 303 is provided with a second drive mechanism 7 fixedly connected to the base. The extended end of the second drive mechanism 7 is rotatably connected to the spiral rod 303. The function of adjusting plate 310 in the secondary separation mechanism 3 is to control the tightness between adjusting plate 310 and shaft 308, thereby controlling the pressure of spring 307 on pressing plate 306, so that duck manure is squeezed more thoroughly, resulting in drier duck manure.

[0035] The bottom of the fixed frame 304 is provided with a dry material tray 106 that is fixedly connected to the base. A pipette 108 is sealed to the bottom of the dry material tray 106. One end of the pipette 108 is sealed to the liquid storage tank 101. The liquid storage tank 101, the pipette 108 and the dry material tray 106 are interconnected.

[0036] The second drive mechanism 7 and the screw rod 303 are flexibly connected. The advantage of this design is that when the compression exceeds the torque of the second drive mechanism 7, the flexible connection will break, preventing the second drive mechanism 7 from being overloaded and burning out the motor.

[0037] An upper guard plate 107 is fixedly connected above the double arc-shaped baffle 1015. The diameter of the upper guard plate 107 is the same as that of the double arc-shaped baffle. The upper guard plate 107 has notches at both ends to facilitate material inlet and outlet. The liquid storage tank 101 has a liquid outlet 1011 at the bottom.

[0038] A feed plate 103 is rotatably connected to one end of the inlet of the liquid storage tank 101. The feed plate 103 has a baffle on its side. Multiple vertical rods 104 are arranged alternately on the upper end of the side that contacts the inlet of the liquid storage tank 101. A support rod 102 is fixedly connected to the bottom of the feed plate 103.

[0039] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0040] Working process: This utility model first unfolds the feed plate 103, and then uses the support rod 102 for positioning and support, so that the feed plate 103 tilts towards the primary separation mechanism 2. By pressing the control button on the control box 4, the high-pressure blower 5, the first drive mechanism 6 and the second drive mechanism 7 are started, and the valve 901 is opened.

[0041] Duck manure is poured onto the feed plate 103 and undergoes initial filtration through multiple vertical rods 104 on the feed plate 103, isolating some large particles on the outside of the machine to prevent large hard objects from damaging the machine. When the duck manure falls from the feed plate 103 into the gap between the primary separation structure 2 and the double arc-shaped baffle 1015, a portion of the liquid in the duck manure flows through the second outlet 1014 to the cleaning pipe 9, and then enters the storage tank 101 through the cleaning pipe 9, flowing out through the first outlet 1011. A pipe can be installed on the first outlet 1011 to flow to a designated location. Some of the moisture in the duck manure is squeezed by the octagonal frame 201, screen 203, and double arc-shaped baffle 1015. The squeezed water flows through the spiral plate 204 into the transfer pipe 8, then through the transfer pipe 8 to the inlet 1013, and from the inlet 1013 to the storage tank 101. The duck manure that has undergone one separation enters the second primary separation mechanism 2 to repeat the above steps. When the screen 203 squeezes the duck manure, some duck manure will remain on the screen 203. The air outlet pipe 501 blows the duck manure off the screen 203 to prevent clogging.

[0042] The duck manure separated by the primary separation mechanism 2 falls onto the discharge trough 105. It then enters the closed chamber 301 through the feed inlet 1051 and is subjected to strong compression by the screw rod 303. The water in the duck manure flows from one end of the dry material tray 106 through the screen 2 305 and into the storage tank 101 through the transfer pipe 108. The dried duck manure falls onto the dry material tray 106 through the extrusion plate 306 and is recycled.

[0043] When cleaning the primary separation mechanism 2 is required, simply close valve 901, pour water onto the feed plate 103, and the water enters the double-arc baffle 1015. Through the agitation of the primary separation mechanism 2, the duck droppings on the double-arc baffle 1015 are cleaned. Then, open valve 901 and the water flows into the storage tank 101 to flush the interior. The secondary separation mechanism 3 only needs to be flushed from the outside. Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
