[0021] Embodiment 1, referring to Figure 1-7 , an excrement recycling collection device for poultry breeding, including a housing 5 with a plurality of support legs 1 installed at the bottom end, one side of the top end of the housing 5 is installed with a feeding mechanism 6 communicating with its interior, one side of the top end of the feeding mechanism 6 is installed with a straw feeding hopper 7 with an anti-blocking impeller 701 inside, and a sewage discharge pipe 4 is installed at the bottom end of the housing 5; A feeding cylinder 3 with an open top end and a conical bottom end is fixed inside the housing 5. A conical rotating disk 9 is rotatably sleeved at the top end of the feeding cylinder 3. The rotating disk 9 is located below the discharge port of the conveyor belt 603 inside the feeding mechanism 6. Above the rotating disk 9, there is a blowing duct 10 installed on the top wall of the housing 5. The cross-section of the blowing duct 10 is annular. The bottom end of the blowing duct 10 is provided with blowing holes. The blowing duct 10 is connected by a duct to a hot air blower located outside the housing 5. A material retaining ring 14 for blocking excrement on the rotating disk 9 is movably installed at the open top end of the feeding cylinder 3. The material retaining ring 14 is provided with a material guiding port 1401. A discharge baffle 13 slidably connected to the rotating disk 9 is provided on one side of the material guiding port 1401 close to the feeding mechanism 6; A rotating ring 901 rotatably sleeved outside the feeding cylinder 3 extends downward from the bottom end of the rotating disk 9. The outer side of the rotating ring 901 is provided with tooth openings 902 arranged in an annular array. A motor III 11 is fixed on the outer side wall of the feeding cylinder 3 through a bracket. The output shaft of the motor III 11 is connected to a gear 12 meshing with the tooth openings 902.

[0022] The feeding mechanism 6 includes a feeding cylinder 601 with a feeding port 605 opened at one end. Both sides inside the feeding cylinder 601 are installed with rotating rollers 604. A conveyor belt 603 is installed between the two rotating rollers 604. A motor II 602 with an output shaft connected to the rotating shaft of one of the rotating rollers 604 is installed outside the feeding cylinder 601.

[0023] A transmission roller 703 is installed on one side of the rotating shaft of the rotating roller 604 and one side of the rotating shaft of the anti-blocking impeller 701, and a transmission belt 702 is installed between the two transmission rollers 703.

[0024] A drying time adjustment mechanism 8 cooperating with the material baffle ring 14 is installed at the top end of the housing 5. The drying time adjustment mechanism 8 includes a fixed bracket 801 fixed on the housing 5 and a connecting rod 806 slidably inserted on the top wall of the housing 5. The connecting rod 806 is slidably inserted on the fixed bracket 801. The bottom end of the connecting rod 806 is connected to the reinforcing rib inside the material baffle ring 14. A positioning gear 804 located at the top end of the housing 5 is also fixed on the connecting rod 806. An external movable engagement of the positioning gear 804 is provided with a fixed gear ring 805 installed on the housing 5. A spring 803 sleeved outside the connecting rod 806 is provided between the positioning gear 804 and the fixed bracket 801. A rotating handle 802 is installed at the top end of the connecting rod 806.

[0025] A plurality of combing teeth 15 located on the rotating disk 9 are installed on the outer side wall of the material baffle ring 14. The sizes of the tooth openings on different combing teeth 15 are different, so as to realize the feeding and turning of the solid fertilizer on the rotating disk 9 and improve the drying effect.

[0026] An inspection opening is formed on the top wall of the housing 5, and an inspection cover 501 is hinged at the inspection opening. After the device runs for a period of time each time, the components inside the housing 5 can be inspected, and at the same time, the mesh holes on the rotating disk 9 can be flushed to prevent them from being blocked. The bottom wall of the housing 5 is arranged in an inward concave shape to facilitate the collection of the liquid in the poultry excrement.

[0027] In use: Start the second motor 602 and the third motor 11. At the same time, add straw crushed to a certain length into the straw feed hopper 7, and continuously pour poultry excrement at the feed inlet 605 of the feeding mechanism 6. The solid-liquid mixture in the poultry excrement is separated into solid and liquid through the conveyor belt 603. The liquid flows into the housing 5 through the feed cylinder 601 and then is discharged and collected through the sewage pipe 4. The output shaft of the second motor 602 drives the rotating roller 604 to rotate, which can drive the conveyor belt 603 to rotate, and convey the separated solid poultry excrement to the rotating disk 9 in the housing 5. The setting of the baffle ring 14 can prevent the solid excrement from directly entering the blanking cylinder 3 from the rotating disk 9. When the rotating roller 604 rotates, on one side, it drives the anti-blocking impeller 701 to rotate through the transmission of the transmission belt 702 and the transmission roller 703, and the straw in the straw feed hopper 7 can be evenly scattered on the solid excrement, achieving adhesion and mixing with the solid excrement and then jointly moving to the rotating disk 9. The output shaft of the third motor 11 drives the gear 12 to rotate, and the gear 12 meshes with the tooth opening 902 on the rotating ring 901, driving the rotating disk 9 to rotate on the blanking cylinder 3. During the rotation process, the hot air blown out by the blowing pipeline 10 further dries the solid poultry excrement, and the dried liquid flows into the inner bottom end of the housing 5 through the mesh holes on the rotating disk 9. The setting of the straw strengthens the air flow gap of the fixed excrement and improves the drying effect. During the rotation of the rotating disk 9, the setting of the combing teeth 15 can continuously stir and turn the solid excrement, improving the drying efficiency. When the solid excrement on the rotating disk 9 moves to the discharge baffle 13, the dried solid poultry excrement is blocked and falls into the blanking cylinder 3 for subsequent operations.

[0028] When it is necessary to adjust the drying time, pull up the connecting rod 806 by rotating the handle 802 upward. The connecting rod 806 drives the positioning gear 804 to be pulled out of the fixed gear ring 805 and then compress the spring 803 upward. The connecting rod 806 drives the baffle ring 14, the discharge baffle 13 and the combing teeth 15 to move upward, and then rotate the handle 802 by a certain angle, finally changing the position of the discharge baffle 13. Then release the handle 802. Under the action of the spring 803, the positioning gear 804 moves downward and is clamped in the fixed gear ring 805. At the same time, through the action of the connecting rod 806, it drives the baffle ring 14, the discharge baffle 13 and the combing teeth 15 to move downward, finally reducing the arc distance that the solid excrement on the rotating disk 9 moves on the rotating disk 9, so as to adjust the drying time, and thus adjust the dehydration rate of the poultry excrement.

[0029] Example 2, as Figure 1 、 Figure 2 、 Figure 8 and Figure 9As shown, different from Embodiment 1, a pressing and forming mechanism 2 for compressing the mixture of poultry excrement and straw into blocks is further installed at the bottom end of the blanking cylinder 3; The pressing and forming mechanism 2 includes a first motor 206 and three pressing cylinders 201 arranged in an annular array on a fixed disk 208. The inner diameter of the pressing cylinder 201 is the same as the diameter of the discharge port at the bottom end of the blanking cylinder 3. The first motor 206 is fixed to the side wall of the blanking cylinder 3 through a mounting bracket 207. The output shaft of the first motor 206 is connected to a fixed disk 208. When the fixed disk 208 drives the three pressing cylinders 201 to rotate and shift: One pressing cylinder 201 is communicated with the bottom end of the blanking cylinder 3; Above another pressing cylinder 201, a telescopic rod 205 fixed to the blanking cylinder 3 is provided. The output shaft of the telescopic rod 205 is connected to a pressing plate 204 slidably connected inside the pressing cylinder 201; And a support plate 202 with a blanking port 2021 is jointly provided at the bottom openings of the above two pressing cylinders 201. The support plate 202 is fixed to the blanking cylinder 3 through a bracket. The support plate 202 is slidably connected to the bottom wall of the pressing cylinder 201. Each time it rotates, one of the three pressing cylinders 201 is aligned with the blanking cylinder 3, one is aligned with the pressing plate 204, and the last one is aligned with the blanking port 2021.

[0030] In order to further improve the fermentation effect and efficiency of the subsequently pressed block fertilizers, a plurality of perforating needles 203 are installed at the bottom end of the pressing plate 204. When the pressing plate 204 moves downward, it can perforate the pressed fertilizer blocks, improve the air permeability of the fertilizer blocks, allow air to better enter the interior of the fertilizer blocks, accelerate the composting and decomposition, and improve the fermentation efficiency of the subsequent fertilizer blocks.

[0031] In use: After drying and dehydration, the poultry excrement mixed with straw is piled up inside the feeding cylinder 3. When the output shaft of the first motor 206 drives the fixed disk 208 to rotate, when a pressing cylinder 201 aligns with the bottom opening of the upper feeding cylinder 3, the poultry excrement inside it falls into the pressing cylinder 201 under the action of gravity and accumulates. Then, the output shaft of the first motor 206 continues to drive the fixed disk 208 to rotate 120 degrees. The pressing cylinder 201 that has fallen into the poultry excrement moves to the lower part of the pressing plate 204. The output shaft of the telescopic rod 205 drives the pressing plate 204 and the perforating needle 203 to move downward, pressing the poultry excrement inside the pressing cylinder 201 into blocky fertilizer. Then, the telescopic rod 205 drives the pressing plate 204 and the perforating needle 203 to return to their original positions. The output shaft of the first motor 206 continues to drive the fixed disk 208 to rotate 120 degrees again. The pressing cylinder 201 filled with blocky fertilizer moves to the discharging station. The blocky fertilizer inside the pressing cylinder 201 falls through the discharging port 2021 under the action of gravity. When it does not fall automatically, a certain pressure can be applied manually to take it out. In this way, after the processed blocky fertilizer is stacked and fermented for a certain period of time, crushing and fertilizing can be achieved.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
