[0032] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Embodiment: A sieve plate device for pre-treatment of pig farm manure resources, such as Figure 1-Figure 5 As shown, including:

[0034] The lower frame 1 is a bottom frame for support, and a middle frame 2 is arranged on the lower frame 1;

[0035] The upper frame 3 is arranged on the middle frame 2. A movable door that can be opened and closed is arranged on the front side of the upper frame 3 to facilitate the subsequent cleaning of the interior of the frame. The top of the upper frame 3 is connected with an inlet pipe 31 for injecting feces and sewage resources. The bottom of the upper frame 3 is connected with a drainage frame 32 that is connected to the middle frame 2. The bottom of the drainage frame 32 is an inclined slope surface for guiding the concentrated outflow of feces and water.

[0036] The pretreatment mechanism 4 is arranged in the upper frame 3. The pretreatment mechanism 4 includes an infusion pump 41 fixedly installed on the top of the upper frame 3 symmetrically on the left and right sides. A group of support plates 42 are respectively arranged on the left and right sides of the top of the upper frame 3. The number of each group of support plates 42 is two. The two support plates 42 in the same group are arranged in a front-to-back interval. A spray gun pipe 43 connected to the water outlet of the infusion pump 41 on the same side is hingedly arranged between the support plates 42 in the same group. The injection ports of the spray gun pipes 43 on both sides are facing the inside of the upper frame 3, and the shaft ends on both sides of the spray gun pipe 43 pass through the corresponding support The plate 42 and both ends of the spray gun tube 43 are fixedly connected with hinged plates 44, which extend longitudinally. A connecting seat 45 is hingedly provided at the end of the hinged plate 44. The connecting seat 45 is arranged horizontally so as to form an angle with the corresponding hinged plate 44. A guide rod 46 is hingedly provided on the connecting seat 45. The guide rod 46 is also arranged horizontally. The ends of the guide rods 46 on the left and right sides slide through the frame wall on the same side of the upper frame 3, so that the guide rods 46 can slide in the left and right directions in the upper frame 3, and the two guide rods on the same side can slide in the left and right directions. A push-pull frame 47 is fixedly connected between the ends of the guide rods 46. By pulling the push-pull frame 47, the guide rod 46 on the same side can be pushed to move, so that the connecting seat 45, the hinged plate 44 and the spray gun tube 43 on the same side are pushed to hinge, thereby adjusting the inclination angle of the spray gun tube 43 to adjust the spray angle. An electric push rod 48 with a telescopic end connected to the push-pull frame 47 on the same side is fixedly installed on the right outer wall of the upper frame 3, which can automatically drive the push-pull frame 47 to move, thereby cooperatively pushing the spray gun tube 43. Tilt and swing, a sieve plate 49 for filtering feces and impurities is also provided in the upper frame 3, the sieve plate 49 is located below the spray gun tubes 43 on both sides, and partition plates 410 are evenly and slidably provided on the sieve plate 49, and filter holes for circulating feces water are arranged on the sieve plate 49, the layout of the partition plates 410 is adapted to the arrangement position of the filter holes, and a connecting rod 411 is fixedly provided between each partition plate 410, and the left and right ends of the connecting rod 411 respectively slide through the side wall of the upper frame 3 and are connected to the push-pull frame 47 on the same side.

[0037] Specifically, it can be seen from the above that the device as a whole presents a three-layer frame structure composed of a lower frame 1, a middle frame 2 and an upper frame 3, providing a complete process from manure input to processing and then to discharge. By operating the push-pull frame 47, the spray angle of the spray gun pipe 43 on the same side can be accurately adjusted. Since the push-pull frames 47 on both sides are connected by connecting rods 411, the two can present synchronous movement. When the push-pull frame 47 on one side is pulled, it will not only change the angle of the spray gun pipe 43 on one side, but also drive the push-pull frame 47 on the other side to perform the same operation through the connecting rod 411, so that the spray gun pipes 43 on both sides can achieve angle adjustment at the same time. Through the setting of this collaborative mechanism, the spray gun pipes 43 on both sides are hinged and moved in opposite ways, thereby generating different spray modes, so as to perform staged spray distance changes, so that the spray gun pipe 43 can apply different degrees of flushing pressure to the impurities on the sieve plate 49, thereby achieving a variety of cleaning effects, effectively separating different types of impurities on the sieve plate 49, and ensuring that pure pig manure can be completely separated and circulated with the manure water.

[0038] In addition, the opening and closing of the filter holes on the sieve plate 49 are controlled by the pushing mechanism of the spacer plate 410, so that the impurities on the sieve plate 49 can be periodically scraped while the manure water continues to flow, helping to separate and remove larger particles trapped on the sieve plate 49, ensuring the thoroughness and effectiveness of manure pretreatment, and providing high-quality treatment effects for subsequent resource recycling.

[0039] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, an extrusion mechanism 5 is provided in the middle frame 2 for processing the sieved pig manure resources. The extrusion mechanism 5 includes an inner cylinder 51 provided inside the middle frame 2, the inner cylinder 51 is connected to the bottom end of the drainage frame 32, a dragon 54 located inside the inner cylinder 51 is rotatably provided between the left and right sides of the middle frame 2, and a motor 53 whose output end is connected to the shaft end of the dragon 54 is fixedly installed on the right outer wall of the middle frame 2 to drive the dragon 54 to rotate and operate, thereby pushing the incoming pig manure together with the manure water for transportation, and a connecting pipe 52 is connected to the left end of the inner cylinder 51, and the connecting pipe 52 serves as a transfer area. The pig manure is pushed and piled up, and a part of the connecting pipe 52 passes through the middle frame 2. A connecting pipe 521 connected to the lower frame 1 is connected at the bottom of the connecting pipe 52, so that the manure in the accumulated pig manure can be discharged through the connecting pipe 521, thereby obtaining a complete pig manure resource. A forming plate 55 is also arranged inside the connecting pipe 52. A through hole is opened on the forming plate 55 along the circumference for conveying the extruded forming of the pig manure. With the continuous operation of the dragon 54, the pig manure is accumulated in the connecting pipe 52, which prompts the pig manure to accumulate and form, thus becoming an initial cake shape for subsequent strip processing.

[0040] Specifically, slots 522 are provided on both the front and rear sides of the inner wall of the connecting tube 52. The slots 522 are L-shaped. Both sides of the forming plate 55 extend outward and bulge out to fit with the slots 522 on the same side, ensuring that the forming plate 55 can be firmly installed on the connecting tube 52. At the same time, this design also facilitates the rapid disassembly of the forming plate 55, thereby simplifying the cleaning and maintenance of the device.

[0041] like Figure 6 and Figure 7 As shown, a rotating disk 56 is also included. The molding plate 55 is rotatably provided with the rotating disk 56. The rotating disk 56 is provided with through holes which are consistent with the layout of the molding plate 55, and is suitable for cooperating with the extrusion of pig manure to form, so that the accumulated pig manure cakes are extruded and discharged through the through holes, thereby presenting strips of pig manure for subsequent recycling and treatment.

[0042] like Figure 1 , Figure 2 and Figure 8 As shown, an extension tube 6 is also included. The connecting tube 52 is provided with the extension tube 6. An electric heating tube 61 arranged around the extension tube 6 is provided on the side wall of the middle frame 2 for drying the formed pig manure strips for subsequent shaping and storage.

[0043] like Figure 1 and Figure 2 As shown, a stirring paddle 7 is also included. A stirring paddle 7 for stirring the feces water is rotatably arranged between the left and right sides of the lower frame 1. A pulley group 71 is arranged between the side end of the stirring paddle 7 and the output shaft of the motor 53 to synchronously drive the stirring paddle 7 to rotate. A drug inlet pipe 72 is connected to the top of the lower frame 1 to add drugs for purifying the feces water, and a drainage pipe 73 is connected to the lower side of the front part of the lower frame 1 to facilitate the discharge of the treated feces water.

[0044] like Figure 2 As shown, a filter plate 8 is also included. A filter plate 8 is also arranged inside the upper frame 3 and is located directly below the sieve plate 49. The hole diameter of the filter plate 8 is smaller than the filter hole of the sieve plate 32, which is used to further screen out impurities.

[0045] When in use, the pig manure resources to be processed are poured into the upper frame 3 through the inlet pipe 31. When the manure enters the upper frame 3, it will fall onto the sieve plate 49 below, and then the infusion pump 41 and the electric push rod 48 are started synchronously. Water is delivered to the corresponding spray gun pipe 43 through the infusion pump 41. The water flows out through the spray gun pipes 43 on both sides, thereby flushing the manure on the sieve plate 49. The pig manure flows downward with the flow of manure water. At the same time, with the push of the electric push rod 48, the corresponding push-pull frame 47 is driven to reciprocate in the left and right directions, and then the connected connecting rod 411 is pulled to move synchronously, so as to pull the partition plate 410 to slide on the sieve plate 49, intermittently blocking the filter on the sieve plate 49. The holes are reciprocated to promote the flow of manure, while impurities will be retained on the sieve plate 49. At the same time, due to the movement of the push-pull frame 47, the connected guide rod 46 will be pulled to move synchronously. When the push-pull frame 47 pushed by the electric push rod 48 is away from the upper frame 3, the guide rod 46 connected thereto will synchronously pull the corresponding connecting seat 45 and the hinge plate 44 to move toward the side wall of the upper frame 3. As the hinge plate 44 is pulled, the connected spray gun pipe 43 is synchronously pulled to tilt on the support plate 42, so that the spray gun pipe 43 on this side is pushed to tilt downward, while the spray gun pipe 43 on the other side will present the above-mentioned reverse push to tilt upward, and the two will spray the sieve plate 49 alternately, so that the sieve plate 49 is The flushing from different spray angles ensures that the impurities in the manure and the manure water are thoroughly screened. Then the filtered manure water flows down through the screen plate 49, and then the impurities are further screened out through the filter plate 8, so that the pure manure water can flow down to the inner tube 51 through the drainage frame 32, and then the motor 53 is started, and the motor 53 drives the dragon 54 to rotate, thereby pushing the pig manure and the manure water to be transported to the left until it moves to the connecting pipe 52. The pig manure entity in the manure water will accumulate in the connecting pipe 52, and the extruded manure water will flow down to the lower frame 1 through the connecting pipe 521. The accumulated pig manure will accumulate more and more as it is pushed and squeezed into a cake shape, and then the rotating disk 56 is driven by the stick to rotate, so that the rotating disk The through holes on the disk 56 are aligned with the through holes on the forming plate 55, and then the accumulated feces cakes will be squeezed into strips through the through holes and discharged, thereby entering the extension tube 6. At the same time, the electric heating tube 61 heats the extension tube 6 to dry the feces strips. Then the staff can collect and process the formed feces strips, and after the feces water enters the lower frame 1, the motor 53 synchronously drives the stirring paddle 7 to rotate through the pulley group 71, thereby stirring the feces water inside the lower frame 1. Then, the working staff can add drugs to the lower frame 1 through the drug inlet pipe 72 to purify the feces water. From then on, an efficient and reliable feces treatment chain can be formed, realizing the effective recovery and resource utilization of pig farm feces and sewage.

[0046] Finally, the movable door of the upper frame 3 is opened to remove the impurities inside the device, and then the forming plate 55 is rotated to make it free from the restriction of the slot 522, so as to clean the accumulated materials inside the inner cylinder 51, and the overall operation process is completed.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
