[0032] In this embodiment, the inner wall of the rotating sleeve 2 is fixedly connected to the partition plate 6; the partition plate 6 divides the internal space of the rotating sleeve 2 into a feces discharge chamber 61 and a drainage chamber 62; the feces discharge chamber 61 is connected to the cutting groove 21, and the rear end of the feces discharge chamber 61 is fixedly connected to the rear cover 63; the drainage chamber 62 is connected to the dewatering groove 22, and the front end of the drainage chamber 62 is fixedly connected to the front cover 64; the inner wall of the rotating groove 12 is rotatably connected to the annular gear 15; the inner edge of the annular gear 15 is connected to the rotating sleeve 2, and the outer edge is engaged with the gear 16; the gear 16 is connected and driven by the output shaft of the motor 17.

[0033] In this embodiment, the partition plate 6 is fixedly connected to the inner wall of the rotating sleeve 2 at an angle; the space of the feces discharge chamber 61 increases from the back to the front; and the space of the drainage chamber 62 increases from the front to the back.

[0034] After collecting the manure in the pig house, start the extension of the hydraulic cylinder 13, the hydraulic cylinder 13 will drive the T-shaped rod 14 to move upward, and the T-shaped rod 14 will drive the pressure plate 5 to move upward during the upward movement. After the pressure plate 5 moves up, it will move out from the upper port of the dehydration chamber 11, and the motor 17 will also drive the gear 16 to rotate. The gear 16 will drive the annular gear 15 to rotate during the rotation. The annular gear 15 is fixedly connected to the rotating sleeve 2, so the rotating sleeve 2 will be driven to rotate during the rotation of the annular gear 15. The inner wall partition plate 6, the front baffle 64 and the rear baffle 63 will be driven to rotate synchronously during the rotation of the rotating sleeve 2. The mesh plate 3 and the dehydration plate 4 will also be driven to rotate synchronously during the rotation of the rotating sleeve 2 until the dehydration plate 4 is located. The position of the dewatering trough 22 corresponds to the position of the dewatering chamber 11 and is connected, and the feces water is poured into the dewatering chamber 11 along the upper port, and the feces water flows from top to bottom along the inner wall of the dewatering chamber 11.

Then the heating wire 51 in the pressing plate 5 works, and the hydraulic cylinder 13 shortens and drives the T-shaped rod 14 to move downward. The T-shaped rod 14 will drive the pressing plate 5 to move downward during the downward movement. The pressing plate 5 will enter the dewatering chamber 11 to squeeze the feces water, and the feces water The sewage is further pressurized and discharged along the dehydration hole 41, and the heating wire 51 heats the pressing plate 5. The heated pressing plate 5 transfers the heat to the dry feces in the dehydration chamber 11, so that the dry feces are heated and dried. The residual sewage in the heating process of the dry feces flows downward again and passes through the dehydration hole 41 to achieve the drying of the dry feces. The sewage discharged from the rear end of the drainage chamber 62 needs to be fermented or flocculated. After the dry feces in the dehydration chamber 11 are dehydrated and dried, the pressing plate 5 will be further pressed down. During the pressing process of the pressing plate 5, the dry feces are squeezed to reduce the volume of the dry feces and achieve the concentration of the dry feces. After the dry feces are concentrated, the motor 17 will drive the gear 16 and the ring gear 15 to rotate. The rotating sleeve 2 rotates under the action of the annular gear 15. During the rotation of the rotating sleeve 2, the dehydration groove 22 and the dehydration chamber 11 will be staggered. After the rotating sleeve 2 rotates, the cutting groove 21 will be aligned with and connected to the dehydration chamber 11, and the pressing plate 5 will be controlled to move down again. During the downward movement of the pressing plate 5, the concentrated dry feces will be squeezed. The arc-shaped plate-shaped dry feces will pass through the mesh plate 3 under the squeezing of the pressing plate 5 to form blocks. The block-shaped dry feces will enter the feces discharge chamber 61 and slide forward along the lower position of the feces discharge chamber 61, and be used as feed raw materials. The cutting is for the convenience of use and transportation. Then the pressing plate 5 moves up again to expose the upper end of the dehydration chamber 11, and a new round of feces water is poured in again and the operation is repeated;

[0035] The present invention squeezes the dry feces in the dehydration chamber 11 through the heated pressing plate 5, so that the sewage in the dry feces in the dehydration chamber 11 is discharged under the action of heating, pressure and gravity, thereby realizing rapid dehydration, drying and concentration of the dry feces. After concentration, the dry feces is cut through the mesh plate 3, which is convenient for the subsequent recycling of the dry feces.

[0036] Embodiment 2: When the pressing plate 5 moves downward along the inner wall of the dehydration chamber 11 , the dehydration groove 22 on the rotary sleeve 2 is kept in communication with the dehydration chamber 11 to control the rotary sleeve 2 to rotate back and forth in the circumferential direction.

[0037] In this embodiment, an annular groove 18 is provided on the inner wall of the rotating groove 12; the annular groove 18 is corrugated; the corrugation direction of the annular groove 18 is the front-to-back direction; the rear block 7 is movably connected in the annular groove 18; the rear block 7 is connected to the outer wall of the rotating sleeve 2; the outer wall of the rotating sleeve 2 is provided with a strip groove 23 along the axial direction; the front block 24 is slidably connected in the strip groove 23; the front block 24 is fixedly connected to the inner wall of the annular tooth 15.

[0038] After the manure is poured into the dehydration chamber 11 along the upper port, the pressing plate 5 will move down under control and enter the dehydration chamber 11. After the pressing plate 5 enters the dehydration chamber 11, dry manure, sewage and more air in the manure will remain in the dehydration chamber 11. As the pressing plate 5 moves down in the dehydration chamber 11, the motor 17 will drive the gear 16 to rotate, and the rotation of the gear 16 will drive the meshing annular gear 15 to rotate. During the rotation of the annular gear 15, the rotating sleeve 2 will be driven to rotate in the rotating groove 12 through the front block 24. During the rotation of the rotating sleeve 2, the rear block 7 on the outer wall will be driven to slide along the annular groove 18. Since the annular groove 18 is a corrugated ring, the rear block 7 slides along the annular groove 18. During the activity of 8, the rotating sleeve 2 will move forward and backward in the axial direction, so that when the pressing plate 5 moves downward, the rotating sleeve 2 will rotate back and forth in the circumferential direction in the rotating groove 12 and move back and forth; from the front side perspective, the counterclockwise rotation of the rotating sleeve 2 will drive the dry feces on the outer wall of the rotating sleeve 2 to move left, that is, the counterclockwise rotation of the rotating sleeve 2 will drive the dry feces in the dehydration chamber 11 to move left, and the top projection of the dehydration groove 22 is larger than the top projection of the dehydration chamber 11, so that during the counterclockwise rotation of the rotating sleeve 2, the dehydration groove 22 will keep covering the dehydration chamber 11, and after the rotating sleeve 2 rotates counterclockwise and drives the dry feces to move left, the dehydration holes 41 around the right side wall of the dehydration chamber 11 will be exposed from the dry feces. , the sewage will gather toward the dehydration holes 41 around the right side wall of the dehydration chamber 11, and cooperate with the downward movement of the pressing plate 5, so that the sewage and air can pass through the dehydration plate 4 more easily; when the rotating sleeve 2 rotates clockwise, the rotating sleeve 2 will drive the dry feces in the dehydration chamber 11 to move rightward, and the dry feces fall on the outer wall of the rotating sleeve 2, and the outer wall of the rotating sleeve 2 and the dry feces have friction, so the dry feces in the dehydration chamber 11 can move with the movement of the rotating sleeve 2. In the process of the dry feces moving rightward, the dehydration holes 41 around the left side of the dehydration chamber 11 are exposed from the dry feces, and the sewage will gather toward the dehydration holes 41 around the left side wall of the dehydration chamber 11, and cooperate with the downward movement of the pressing plate 5, so that the sewage and air can pass through the dehydration plate 4; at the same time In principle, during the forward movement of the rotating sleeve 2, the rotating sleeve 2 will drive the dry feces in the dehydration chamber 11 to move forward, and the dehydration holes 41 around the rear side wall of the dehydration chamber 11 will be exposed from the dry feces, and the sewage or gas will converge toward the dehydration holes 41 around the rear side wall of the dehydration chamber 11, and cooperate with the downward movement of the pressing plate 5 to allow the sewage and air to pass through the dehydration plate 4. Similarly, during the backward movement of the rotating sleeve 2, the rotating sleeve 2 will drive the dry feces in the dehydration chamber 11 to move backward, and the dehydration holes 41 around the front side wall of the dehydration chamber 11 will be exposed from the dry feces, and the sewage or gas will converge toward the dehydration holes 41 around the front side wall of the dehydration chamber 11, and cooperate with the downward movement of the pressing plate 5 to allow the sewage and air to pass through the dehydration plate 4.

[0039] In this embodiment, the rotating sleeve 2 moves back and forth in the circumferential direction and back and forth during the downward movement of the pressing plate 5, so that the rotating sleeve 2 can drive the dry feces in the dehydration chamber 11 to form a gap with the vertical inner wall of the dehydration chamber 11, so that the sewage and gas in the dehydration chamber 11 can quickly pass through the dehydration plate 4 without passing through the dry feces, thereby further improving the dehydration and drying efficiency of the dry feces.

[0040] Embodiment 3: The lower surface of the pressing plate 5 is provided with a mesh groove 52 corresponding to the mesh plate 3; the mesh groove 52 is composed of a combination of vertical and horizontal cross grooves; after the pressing plate 5 moves downward, the upper edge of the mesh plate 3 can enter into the mesh groove 52.

[0041] In this embodiment, the mesh groove 52 is connected with a mesh bar 53 in an upward and downward sliding manner; the upper surface of the mesh bar 53 is connected to the bottom of the mesh groove 52 via a spring 54 .

[0042] In this embodiment, a slide groove 55 is provided on the edge of the pressure plate 5 toward the center; a slider 56 is slidably connected in the slide groove 55; one end of the slider 56 is located between the mesh strip 53 and the bottom of the mesh groove 52, and the other end can extend out of the slide groove 55; one end of the slider 56 is provided with a first inclined surface 57 tilted downward, and the other end of the slider 56 is provided with a second inclined surface 58 tilted upward; a notch 19 is provided at the lower position of the side wall of the dehydration chamber 11; the other end of the slider 56 can enter into the notch 19.

[0043] During the downward movement of the pressing plate 5, the pressure in the dehydration chamber 11 increases. In addition, during the pressing plate 5 squeezing the dry feces, the dry feces will also give the pressing plate 5 a reaction force. Under the pressure of air, hydraulic pressure or object squeezing, the lower surface of the pressing plate 5 will be subjected to an upward force, and the pressing plate 5 will not move upward under the control of the T-bar 14 and the hydraulic cylinder 13. The mesh bar 53 will transmit the force to one end of the slider 56. Under the inclined transmission, the other end of the slider 56 will be against the inner wall of the dehydration chamber 11, so that the other end of the slider 56 is on the inner wall of the dehydration chamber 11. The mesh strips 53 are restricted and cannot slide along the slide grooves 55 and move out, so that the mesh strips 53 cannot move up in the mesh grooves 52, thereby ensuring the integrity of the lower surface of the pressing plate 5. As the pressing plate 5 continues to move downward, the dry manure is dehydrated, dried and compressed to form a dry manure board. Then the rotating sleeve 2 will rotate to align the cutting grooves 21 with the dehydration chamber 11, and the mesh plate 3 will align with the lower end of the dehydration chamber 11. Then the pressing plate 5 will move downward to squeeze the dry manure board. The dry manure board will be pressed into the cutting grooves 21. After passing through the mesh plate 3, the dry manure board will be cut into multiple blocks of dry manure. As the pressing plate 5 moves downward, the dry manure board will be cut into multiple blocks of dry manure. The pressing plate 5 moves downward, and after the lower surface of the pressing plate 5 contacts the mesh plate 3, the slide groove 55 on the edge of the pressing plate 5 is aligned with the notch 19. As the pressing plate 5 continues to move downward, the mesh plate 3 will enter the mesh groove 52 to squeeze the mesh strips 53. The mesh strips 53 move upward to overcome the elastic force of the spring 54 and move upward. The upward movement of the mesh strips 53 will squeeze the first inclined surface 57 at one end of the slider 56, so that the other end of the slider 56 enters the notch 19 for avoidance. After the upper part of the mesh plate 3 enters the mesh groove 52, the fibers connected to the dry manure blocks will be broken. Pig manure contains some undigested fibers, which require the mesh plate 3. After entering the mesh groove 52 to complete the above-mentioned function, as the pressing plate 5 moves up again, the slide groove 55 is staggered with the notch 19, and the second inclined surface 58 at the other end of the slider 56 is squeezed by the upper edge of the notch 19 and slides along the slide groove 55 toward the center of the pressing plate 5. The slider 56 will drive the first inclined surface 57 to squeeze the mesh strip 53 downward, and the mesh strip 53 will also move downward under the elastic force of the spring 54. The slider 56 will return to the slide groove 55, and the mesh strip 53 will also move downward to seal the mesh groove 52, so that the lower surface of the pressing plate 5 is intact, and impurities are prevented from remaining in the mesh groove 52.

[0044] In this embodiment, the mesh grooves 52 on the lower surface of the pressing plate 5 and the mesh strips 53 in the mesh grooves 52 enable the pressing plate 5 to move downward to better break the concentrated and formed dry manure board, thereby ensuring the dry manure forming and processing effect while avoiding clogging of the mesh grooves 52.

[0045] Embodiment 4: The thickness of the dehydration plate 4 is smaller than that of the dehydration groove 22; the dehydration plate 4 is movably connected to the dehydration groove 22; the inner port of the dehydration groove 22 is fixedly connected to the frame edge 8; the frame edge 8 is provided with a driven groove 81 on the side facing the dehydration plate 4; the driven block 82 is connected to the bottom of the driven groove 81 by a tension spring 83; the outer wall of the rotating sleeve 2 is provided with an active groove 25; the rear block 7 is connected to the active groove 25 by a sliding seal; the active groove 25 is connected to the bottom of the driven groove 81 by a liquid hole 26; the active groove 25 and the driven groove 81 are filled with liquid medium; the depth of the annular groove 18 decreases from bottom to top;

[0046] After the rotating sleeve 2 drives the dewatering groove 22 to rotate and aligns with the dewatering chamber 11 and is connected, the rotating sleeve 2 will drive the rear block 7 to move to the highest position in the annular groove 18. The rear block 7 is shallowest in the annular groove 18. During the process of the rear block 7 moving to the highest position of the annular groove 18, it will slide along the active groove 25, and the rear block 7 will squeeze the liquid medium in the active groove 25, so that the liquid medium in the active groove 25 will enter the driven groove 81 along the liquid hole 26 and squeeze the driven block 82. During the outward movement of the driven block 82, the tension of the tension spring 83 will be overcome, and part of the driven block 82 will extend out of the driven groove 81 and drive the dewatering plate 4 to move closer to the dewatering groove 22. After the pressing plate 5 moves down and compresses the dry feces, a dry feces plate is formed, and then the rotating sleeve 2 will rotate and drive the cutting groove 21 close to the dehydration chamber 11, the rotating sleeve 2 drives the dehydration groove 22 to be staggered with the dehydration chamber 11, and the rotating sleeve 2 will also drive the rear block 7 to move to the deep position in the annular groove 18, so that the rear block 7 moves out of the active groove 25 to avoid it. The tension spring 83 will pull the driven block 82 close to the bottom of the driven groove 81 and squeeze the liquid medium in the driven groove 81, so that the liquid medium in the driven groove 81 enters the active groove 25 along the liquid hole 26. The active block is squeezed by the liquid medium and extends out, and the driven block 82 drives the dehydration plate 4 to approach the frame edge 8 and then away from the dry manure plate to form a gap, thereby facilitating the rotation of the rotating sleeve 2, avoiding the friction between the dehydration plate 4 and the dry manure plate affecting the rotation of the rotating sleeve 2, thereby improving the stability of pig house manure treatment.
