The bottom of the feed frame 1 is fixedly connected to a fixed baffle 101, and the fixed baffle 101 is used to shield the liquid separated from the cow dung. The feed frame 1 is rotatably connected to the crushing roller 103, and two crushing rollers 103 are provided. The crushing roller 103 is fixedly connected to the rotating bracket 1033, and one end of the rotating bracket 1033 passes through the feed frame 1 and is connected to the external power.

The two crushing gears 104 are meshed, and a crushing block 1031 is fixedly connected to the outside of the crushing roller 103. The crushing blocks 1031 on the two crushing rollers 103 are staggered so that the cow dung can be squeezed and crushed during the rotation of the two crushing rollers 103. A receiving frame 2 is fixedly connected to the fixed baffle 101, and the receiving frame 2 is located below the crushing roller 103. The receiving frame 2 is used to receive the cow dung crushed by the crushing roller 103. The drainage component is installed in the crushing roller 103. The drainage component is used to discharge the liquid entering the crushing roller 103. The rotary dehydration mechanism is installed in the fixed baffle 101, and the rotary dehydration mechanism performs preliminary dehydration on the crushed cow dung.

[0037] like Figure 3 and Figure 4 As shown, the drainage assembly includes a water permeable hole 1032, a screw push rod 1034, an arc shield 105, an arc blocking rod 1051 and a fixed side plate 106. The crushing roller 103 is provided with a water permeable hole 1032. During the crushing process, part of the liquid in the cow dung will enter the crushing roller 103 through the water permeable hole 1032. The crushing roller 103 is fixedly connected with a screw push rod 1034. The feed frame 1 is fixedly connected with an arc shield 105. The arc shield 105 is fixedly connected with an arc blocking rod 1051.

The fixed side plate 106 blocks the side of the crushing roller 103 away from the crushing gear 104, and an outlet is opened on the fixed side plate 106. During the rotation of the crushing roller 103, the spiral push rod 1034 pushes the liquid in the crushing roller 103 toward the fixed side plate 106, so as to discharge the liquid entering the crushing roller 103 from the outlet on the fixed side plate 106.

[0038] A crushing roller 103 is driven to rotate by an external power, and the two crushing rollers 103 rotate in opposite directions under the drive of the crushing gear 104 to crush the cow dung passing through the two crushing rollers 103, and the collected cow dung is put into the feeding frame 1, and the cow dung slides along the feeding frame 1 to the crushing roller 103. When the cow dung passes through the crushing roller 103, it will be squeezed and crushed by the crushing roller 103. During the squeezing process, part of the liquid enters the crushing roller 103 through the water permeable hole 1032. The liquid in the crushing roller 103 is blocked by the arc-shaped blocking rod 1051 and cannot flow out through the water permeable hole 1032. As the crushing roller 103 rotates continuously, the spiral push rod 1034 rotates and pushes the liquid in the crushing roller 103 to the fixed side plate. 106 moves, and finally part of the liquid separated from the cow dung is discharged outward from the outlet opened on the fixed side plate 106. In the process of crushing the cow dung, after the crushing block 1031 on the crushing roller 103 crushes the cow dung, when the crushing block 1031 passes through the arc shield 105, the cow dung remaining on the surface of the crushing block 1031 will be shoveled away by the arc shield 105, and the crushed cow dung falls downward into the receiving frame 2. In the process of the crushing roller 103 rotating and crushing the cow dung, it will drive the rotary dehydration mechanism to operate. In the process of the rotary dehydration mechanism operating, the cow dung in the receiving frame 2 will fall downward into the rotary dehydration mechanism, and the rotary dehydration mechanism will throw the liquid in the cow dung outward to dehydrate the cow dung.

[0039] Embodiment 2: Based on embodiment 1, Figure 5-Figure 12 As shown, the rotary dehydration mechanism includes a gearbox 102, a transmission shaft 1021, a bevel gear transmission group 1022, a belt transmission group 1023, a rotary dehydration cylinder 3, a fixed plate 301, a discharge cylinder 302, a V-shaped frame 4, a feeding assembly and a discharge assembly.

[0040] When the crushing roller 103 rotates, the transmission shaft 1021 is driven to rotate through the rotating bracket 1033 and the bevel gear transmission group 1022. When the transmission shaft 1021 rotates, the rotary dehydration cylinder 3 is driven to rotate through the belt transmission group 1023, so as to drive the cow dung falling into it to rotate and throw out part of the liquid in the cow dung. The liquid separated from the cow dung flows out through the water outlet on the side wall of the rotary dehydration cylinder 3. Under the cover of the fixed baffle frame 101, the liquid thrown out of the rotary dehydration cylinder 3 will not splash outward. The liquid thrown out of the rotary dehydration cylinder 3 will eventually fall on the fixed plate 301, and then flow out through the outlet connected to the V-shaped frame 4 through the fixed plate 301. Every time the rotary dehydration cylinder 3 rotates for a certain period of time, the discharging component will automatically push the cow dung that has been dried inside it into the discharging cylinder 302, and then the feeding component will run and add new cow dung into the rotary dehydration cylinder 3 to perform rotary dehydration treatment on the cow dung.

[0041] like Figure 6-Figure 9 As shown, the discharging assembly includes a connecting shaft 3021, a reciprocating screw rod 3022, an inner gear ring 303, a transmission gear 304, a support shaft 3041, a rotating gear 305, a lifting frame 307, a lifting push rod 308 and a lifting ring 3081.

During the rotation of the reciprocating screw 3022, the lifting frame 307 moves up and down along the reciprocating screw 3022, and a lifting ring 3081 is fixedly connected to the lifting push rod 308.

[0042] like Fig.11 and Fig.12As shown, the feeding assembly includes a rotating shaft 201, an arc-shaped slide bar 2011, a lifting base plate 202, an arc-shaped slide groove 2021, a U-shaped fixed rod 203, a sliding inclined rod 204 and an L-shaped rod 309, the top of the reciprocating screw rod 3022 is rotatably connected to the rotating shaft 201, the outer side of the rotating shaft 201 is fixedly connected to the arc-shaped slide bar 2011, an outlet is provided in the receiving frame 2, and the outlet of the receiving frame 2 is slidably connected to the lifting base plate 202, the lifting base plate 202 is slidably connected to the rotating shaft 201, the lifting base plate 202 is provided with an arc-shaped slide groove 2021, the arc-shaped slide bar 2011 can slide along the arc-shaped slide groove 2021, and the rotating shaft 201 is rotated. 01 is fixedly connected with a U-shaped fixed rod 203 at the top, and a sliding inclined rod 204 is slidably connected in the receiving frame 2. The U-shaped fixed rod 203 is fixedly connected with the sliding inclined rod 204. When the lifting base plate 202 rises, the rotating shaft 201 is driven to rotate through the arc-shaped sliding rod 2011. The rotation of the rotating shaft 201 drives the sliding inclined rod 204 to slide along the receiving frame 2 through the U-shaped fixed rod 203, so as to push the cow dung in the receiving frame 2 to the outlet. The lifting push rod 308 is fixedly connected with an L-shaped rod 309. The L-shaped rod 309 is fixedly connected with the lifting base plate 202. When the lifting push rod 308 moves up and down, it drives the lifting base plate 202 to move up and down through the L-shaped rod 309.

[0043] When the rotary dehydration cylinder 3 rotates, the inner gear ring 303 is driven to rotate. The rotation of the inner gear ring 303 drives the rotating gear 305 to rotate through the transmission gear 304. When the rotating gear 305 rotates, the connecting shaft 3021 is driven to rotate through the reciprocating screw rod 3022. During the rotation of the reciprocating screw rod 3022, the lifting frame 307 slides up and down along the reciprocating screw rod 3022. In the initial state, the lifting frame 307 is located at the bottom of the reciprocating screw rod 3022. At this time, the bottom surfaces of the lifting push rod 308 and the lifting ring 3081 are in contact with the bottom surface of the rotary dehydration cylinder 3. At this time, the lifting bottom plate 202 blocks the bottom outlet of the receiving frame 2. When the reciprocating screw rod 3022 rotates, the lifting frame 307 moves upward first. When the lifting frame 307 rises, it drives the L-shaped rod 309 to rise through the lifting push rod 308. When the L-shaped rod 309 rises, it pushes the lifting bottom plate 202 The bottom plate 202 of the receiving frame 2 is lowered to the bottom of the receiving frame 2, and the bottom plate 202 of the receiving frame 2 is lowered to the bottom of the receiving frame 2. ... 07 has not yet dropped to the lowest point, the lifting frame 307 will continue to move downward along the reciprocating screw rod 3022 for a distance. During this process, as the rotary dehydration cylinder 3 continues to rotate, the cow dung in the rotary dehydration cylinder 3 will contact the lifting push rod 308, and since the lifting push rod 308 is an inclined rod inclined toward the discharge cylinder 302, the cow dung in the rotary dehydration cylinder 3 will move along the lifting push rod 308 toward the discharge cylinder 302 after contacting the lifting push rod 308. When the lifting frame 307 drops to the lowest point of the reciprocating screw rod 3022, the cow dung in the rotary dehydration cylinder 3 has entered the discharge cylinder 302 along the lifting push rod 308, and then the lifting frame 307 rises along the reciprocating screw rod 3022 and drives the L-shaped rod 309 to rise again through the lifting push rod 308, so as to push the cow dung in the receiving frame 2 into the rotary dehydration cylinder 3, thereby realizing the function of adding cow dung to the rotary dehydration cylinder 3 and pushing the dehydrated cow dung into the discharge cylinder 302.

[0044] Embodiment 3: Based on embodiment 2, Fig. 9 and Fig.10As shown, it also includes a bulk material cone 306, a fixed knocking block 3091 and a fixed protruding rod 3092. The upper end of the reciprocating screw 3022 is rotatably sleeved with the bulk material cone 306. The L-shaped rod 309 passes through the bulk material cone 306 and is slidably connected thereto. The fixed knocking block 3091 is fixedly connected to the L-shaped rod 309, and the fixed protruding rod 3092 is fixedly connected to the bottom of the bulk material cone 306. During the rising process of the L-shaped rod 309, the fixed knocking block 3091 collides with the fixed protruding rod 3092 to vibrate the bulk material cone 306, so that the cow dung on the top surface of the bulk material cone 306 slides down quickly.

[0045] The cow dung in the receiving frame 2 falls downward from the bottom outlet thereof into the rotary dehydration cylinder 3 and will first contact with the bulk material cone 306. The cow dung will scatter along the bulk material cone 306 into the rotary dehydration cylinder 3, thereby preventing the cow dung from directly entering the discharge cylinder 302 without being dehydrated. At the same time, it can also prevent the cow dung from accumulating, thereby achieving a better dehydration effect. When the L-shaped rod 309 rises, it will drive the fixed knocking block 3091 to rise. When the fixed knocking block 3091 contacts the fixed convex rod 3092, the bulk material cone 306 will vibrate, causing the cow dung on the bulk material cone 306 to fall quickly. 091 is made of elastic material, and the fixed protrusion 3092 is provided with multiple positions that can contact the fixed knocking block 3091. During the rising process of the L-shaped rod 309, the fixed knocking block 3091 knocks the fixed protrusion 3092 and the bulk material cone 306 for many times. When the L-shaped rod 309 descends, the fixed knocking block 3091 knocks the fixed protrusion 3092 and the bulk material cone 306 again. During the up and down movement of the L-shaped rod 309, the bulk material cone 306 is knocked and vibrated for many times, so that the cow dung on the bulk material cone 306 can fall off quickly, and at the same time, it can prevent the cow dung from remaining on the surface of the bulk material cone 306.

[0046] like Fig.13 and Fig.14As shown, it also includes a turntable 3023, a screw extruder 5, a mobile screen frame 501, a rotating push rod 502, a swing rod 503 and a swing discharge plate 504. The bottom of the connecting shaft 3021 is fixedly connected to the turntable 3023, and the reciprocating screw rod 3022 drives the turntable 3023 to rotate through the connecting shaft 3021. The top of the feed port of the screw extruder 5 is fixedly connected to the V-shaped frame 4. The mobile screen frame 501 is slidably installed in the screw extruder 5. The turntable 3023 is connected to the mobile screen frame 501 through the rotating push rod 502. One end of the rotating push rod 502 is rotatably connected to the turntable 3 023 bottom, the other end of the rotating push rod 502 is rotatably connected to the mobile screen frame 501. When the turntable 3023 rotates, the rotating push rod 502 drives the mobile screen frame 501 to slide back and forth in the screw extruder 5 to cooperate with the screw extruder 5 to extrude cow dung and avoid the sieve holes of the mobile screen frame 501 from being blocked. The right end outlet of the screw extruder 5 is rotatably connected to a swinging discharge plate 504, and the right end of the mobile screen frame 501 is rotatably connected to a swing rod 503, and the other end of the swing rod 503 is rotatably connected to the outside of the swinging discharge plate 504.

[0047] After the cow dung enters the discharge barrel 302, it will fall downward into the screw extruder 5. The screw extruder 5 will squeeze the cow dung again to fully squeeze out the moisture inside it. When the connecting shaft 3021 rotates, it drives the turntable 3023 to rotate. When the turntable 3023 rotates, it drives the movable screen frame 501 to slide back and forth in the screw extruder 5 by rotating the push rod 502. When the movable screen frame 501 slides back and forth, it cooperates with the screw extruder 5 to squeeze the cow dung. The squeezed moisture is discharged downward from the water outlet frame of the screw extruder 5. The squeezed cow dung is discharged from the right outlet of the screw extruder 5 and falls on the swinging discharge plate 504. When the movable screen frame 501 slides back and forth, it can drive the swinging discharge plate 504 to swing up and down through the swing rod 503 to throw out the squeezed cow dung.

[0048] like Fig.14 and Fig.15As shown, it also includes a drying box 6, a rotating shaft 601, a connecting rod 602, a heating wire 603, a drying cylinder 604 and a drying baffle 605. The right end of the screw extruder 5 is provided with a drying box 6, and the rotating shaft 601 is rotatably connected in the drying box 6. The top surface of the rotating shaft 601 is rotatably connected to the connecting rod 602, and the other end of the connecting rod 602 is rotatably connected to the movable screen frame 501. During the reciprocating movement of the movable screen frame 501 in the screw extruder 5, the rotating shaft 601 is driven by the connecting rod 602 to continuously rotate forward and reverse. A heating wire 603 is installed in the drying box 6, a drying cylinder 604 is fixedly connected in the drying box 6, a drying baffle 605 is fixedly connected to the rotating shaft 601, and the drying baffle 605 is located in the drying cylinder 604. The heating wire 603 increases the temperature in the drying box 6 and dries the cow dung in the drying cylinder 604. The cow dung squeezed out of the screw extruder 5 enters the drying baffle 605 in the drying cylinder 604. As the rotating shaft 601 rotates forward and reverse continuously, the dried cow dung on the drying baffle 605 falls downward.

[0049] The cow dung squeezed out by the screw extruder 5 falls onto the drying baffle 605 in the drying cylinder 604 in the drying box 6 through the swinging discharge plate 504. The heating wire 603 heats the air in the drying box 6 to increase the temperature in the drying box 6 and dry the cow dung on the drying baffle 605. During the reciprocating sliding of the movable screen frame 501, the connecting rod 602 drives the rotating shaft 601 to rotate alternately forward and reverse continuously. During the alternate forward and reverse rotation of the rotating shaft 601, the dried cow dung on the drying baffle 605 will be thrown out and fall downward.

[0050] like Fig.15 and Fig.16 As shown, it also includes an outer gear ring 606, a sieve plate 607, a fixed connecting rod 608, a transmission wheel 609, a stirring gear 610 and a stirring rod 611. The outer gear ring 606 is fixed to the bottom of the drying cylinder 604, the sieve plate 607 is fixed to the drying box 6, the fixed connecting rod 608 is fixed to the rotating shaft 601, the top of the fixed connecting rod 608 is rotatably connected to the transmission wheel 609, the transmission wheel 609 is meshed with the outer gear ring 606, the bottom of the fixed connecting rod 608 is rotatably connected to the stirring gear 610, the transmission wheel 609 It is coaxially fixed with the stirring gear 610, and a stirring rod 611 is fixed at the bottom of the stirring gear 610. The rotating shaft 601 drives the transmission wheel 609 to move through the fixed connecting rod 608. The transmission wheel 609 moves and rotates around the outer gear ring 606, thereby driving the stirring gear 610 to rotate. The stirring gear 610 rotates through the stirring rod 611 to move the cow dung on the sieve plate 607 to increase the drying speed. The dried cow dung is broken up by the stirring rod 611 and falls downward from the sieve holes on the sieve plate 607.

[0051] The cow dung that falls from the drying baffle 605 will fall on the sieve plate 607. To prevent the cow dung from being insufficiently dried, when the rotating shaft 601 rotates, it will drive the transmission wheel 609 to move along the outer gear ring 606 through the fixed connecting rod 608. The transmission wheel 609 drives the stirring gear 610 to rotate. The stirring rod 611 at the bottom of the stirring gear 610 continuously stirs the cow dung on the sieve plate 607 and also breaks up the cow dung to avoid accumulation of the cow dung and ensure that the inside of the cow dung can also be dried. The broken up cow dung falls downward through the sieve holes on the sieve plate 607.
