[0003] The key to manure air-drying equipment is how to quickly, economically, and reasonably reduce the moisture content of manure to a specified value. Currently, in the application of manure air-drying equipment, a relatively economical and reasonable solution is to use the heat generated by the chickens in the chicken house to dry the manure through the exhaust fan at the rear of the chicken house. When laying the material, the current equipment mixes the dry and wet materials in advance and then lays them on the manure board. In this way, the wetter materials will stick to the manure board and are not easy to fall off. At the same time, it will cause the holes in the manure board to be blocked, which will affect the drying effect. Therefore, there is an urgent need for a new type of manure air-drying equipment and manure air-drying method to solve the above problems. Utility Model Content

[0029] The following is a clear and complete description of the present invention with reference to the accompanying drawings and embodiments:

[0030] like Figures 1 to 11As shown, the novel manure drying equipment described in the utility model includes a frame 1, on which multiple groups of parallel manure conveying plates 2 with opposite running directions are arranged at intervals, so that the manure conveying plates 2 of the upper and lower adjacent layers are connected end to end to complete the transportation of manure, extend the transportation distance of manure, and improve the drying effect. The outlet end of the manure conveying plate 2 located at the bottom layer is provided with a feeding mechanism 3, which is used to receive and transport the output air-dried manure and sewage. The output end of the feeding mechanism 3 is connected to the dry material lifting mechanism 4, and the dry material lifting mechanism 4 is vertically arranged on one side of the frame 1; two upper and lower discharge channels 5 are provided on the dry material lifting mechanism 4, and the discharge channel 5 located on the lower layer is connected to the dry material laying mechanism 6 so as to transport a part of the dried manure and sewage to the dry material laying mechanism 6, and the discharge channel 5 on the upper layer is used to output the remaining dried manure and sewage for use; the dry material laying mechanism 6 is arranged above the top manure conveying plate 2; a discharge port is provided at the bottom of the dry material laying mechanism 6, which is used to transport part of the air-dried manure and sewage to the manure conveying plate 2 in an orderly manner; a wet material laying mechanism that can swing left and right is provided on the frame 1 on one side of the dry material laying mechanism 6, so that the wet manure and sewage can be evenly spread on the air-dried manure and sewage. The utility model uses air-dried manure as a base and spreads it on the upper manure conveying plate 2, thereby avoiding direct contact between wet manure and the manure conveying plate 2, and further preventing the wet manure from adhering to the manure conveying plate 2 due to its high viscosity and being difficult to fall off and clogging the ventilation holes on the manure conveying plate 2, thereby ensuring the air-drying efficiency and effect of the manure.

[0031] Among them, in this embodiment, the feeding mechanism 3, the dry material lifting mechanism 4 and the dry material laying mechanism 6 are all screw conveyors; and the feeding mechanism 3 is a screw conveyor with an open top, so that the feces on the bottom feces conveying plate 2 can be transported therein in time; an output port is provided on one side of the feeding mechanism 3 and is connected to the dry material lifting mechanism 4; the dry material lifting mechanism 4 is a screw conveyor with two discharge channels 5 provided on the upper part of the sealed outer shell, so as to transport the air-dried feces into the dry material laying mechanism 6 and output the remaining dry feces; in addition, the discharge pipe on the dry material lifting mechanism 4 connected to the dry material laying mechanism 6 is inclined from top to bottom, so that the dry feces can be smoothly transported into the dry material laying mechanism 6.

[0032] In addition, a discharge port is provided at the bottom of the dry material laying mechanism 6, and a height-adjustable material level adjustment plate 7 is provided on the side of the dry material laying mechanism 6 close to the wet material laying mechanism. Specifically, a screw 8 is provided on the material level adjustment plate 7, which is movably extended from the mounting plate provided on the dry material laying mechanism 6 and is provided with a fixing nut on the outside. When it is necessary to adjust the paving thickness of the air-dried manure, the fixing nut is loosened and the screw 8 is moved up and down. Then, as the manure conveying plate 2 moves, the material level adjustment plate 7 will scrape off the manure that is higher than the specified position. In addition, in this embodiment, a dry material detection sensor 9 is provided at the end of the dry material laying mechanism 6 away from the discharge channel 5. When the air-dried manure is transported from one end of the dry material laying mechanism 6 to the other end, the dry material detection sensor 9 detects the manure, and the dry material laying mechanism 6 stops working, and the manure conveying plate 2 starts to move, ensuring that the dry manure is evenly laid along the width direction of the manure conveying plate 2, and preventing the situation where there is manure only on one side of the manure conveying plate 2 in the width direction.

[0033] Furthermore, a scraper assembly is provided at the bottom of the frame 1, and an inclined guide plate 10 is provided on the side of the feed mechanism 3 near the scraper assembly. The top of the guide plate 10 extends to the open top of the feed mechanism 3, so that as the scraper assembly operates, spilled feces and sewage are scraped into the feed mechanism 3. Specifically, the scraper assembly includes a chain 11 provided on the frame 1, which engages with sprockets 12 provided at both ends of the frame 1. A plurality of scrapers 13 are provided at intervals on the chain 11.

[0034] Furthermore, a mixing paddle 21 is provided on the top of the frame 1. The mixing paddle 21 is located above the top manure conveying plate 2, and the mixing paddle 21 is located at one end away from the dry material laying mechanism 6. The mixing paddle 21 is driven by a motor and can mix and stir the manure and sewage running here, accelerate the up and down flow of the airflow, and improve the air drying effect.

[0035] Furthermore, the wet material laying mechanism includes a support base 22, which is positioned at an end away from the dry material laying mechanism 6. A bracket 23 is rotatably mounted on the support base 22 via a slewing bearing, and a paving conveyor belt 24 is mounted on the bracket 23. Two retractable linear drive members 25 are symmetrically hinged to the support base 22, with opposing ends of the drive members hinged to a connecting base mounted on the bracket 23. The two drive members cooperate in telescopic motion, driving the bracket 23 and the paving conveyor belt 24 to reciprocate, thereby achieving the spreading of wet manure. The linear drive member 25 can be an electric push rod or a hydraulic cylinder. In this embodiment, a hydraulic cylinder is preferably used to ensure stable power output and the stability of the paving conveyor's swing. The two hydraulic cylinders are respectively connected to a hydraulic pump station 26 located on one side of the frame 1 via hydraulic pipelines.

[0036] In addition, baffle plates 27 are provided on both sides of the paving conveyor belt 24. The baffle plates 27 are used to prevent the wet manure and sewage from falling from both sides of the paving conveyor belt 24 during the swinging process without being transported to the outlet end; limit switches 28 are provided on the support seats 22 on both sides of the paving conveyor belt 24 to control the forward and backward swinging position of the paving conveyor belt 24. A baffle 29 is movably provided near the output end of the paving conveyor belt 24. A rotating shaft is fixedly provided on the baffle 29, and the rotating shaft is movably connected to the support plates 30 provided on the baffle plates 27 on both sides. An eccentric wheel 31 is provided on the rotating shaft at one end, and a trigger switch 32 is provided on the support plate 30 below the eccentric wheel 31. When wet manure moves past the baffle 29 on the paving conveyor belt 24, the baffle 29 will drive the rotating shaft and eccentric wheel 31 to rotate a certain angle. The eccentric wheel 31 rotates and presses the trigger switch 32, proving that there is manure on the paving conveyor belt 24. At this time, the two hydraulic cylinders are allowed to operate, driving the paving conveyor belt 24 to swing back and forth to ensure the uniformity of material paving. When there is no material on the paving conveyor belt 24, the baffle 29 is reset, and at the same time, the rotating shaft and eccentric wheel 31 are driven to rotate and reset. At this time, the eccentric wheel 31 no longer presses the trigger switch 32, the two sets of hydraulic cylinders stop running, and the paving conveyor belt 24 stops swinging.

[0037] Furthermore, conveying chains 33 are provided at both ends of the manure conveying board 2, and the conveying chains 33 are connected to the conveying sprockets 34 provided at both ends of the frame 1; each manure conveying board 2 is detachably provided with a plug 14 at both ends, and the plug 14 is preferably made of plastic material, which can not only reduce the overall weight of the manure board, but also facilitate standardized processing and production, and the raw materials are easily available and low in cost; in addition, threaded holes are provided at the bottom of the plug 14 and the bottom of both ends of the manure conveying board 2, and the plug 14 is preferably detachably connected to the manure conveying board body by bolts; each plug 14 is respectively provided with a roller 15 and a mounting pin 16 at both ends along its length direction, and the mounting pin 16 is used to be installed with the chain hole on the conveying chain 33. In addition, the roller 15 and the mounting pin 16 are also detachably connected to the manure conveying board 2, so as to solve the problems of deformation and error caused by welding in the existing technology, improve production efficiency and accuracy, and facilitate subsequent targeted maintenance and replacement to reduce production costs. Specifically, the roller 15 is rotatably mounted on the bolt, and the bolt passes through a through hole formed on the plug 14 and is fixedly connected by a nut.

[0038] In this embodiment, a support portion 17 is detachably provided in the middle of the manure conveying plate 2, and a support wheel 18 is rotatably provided on the support portion 17. The provision of the support portion 17 and the support wheel 18 is used to provide central support for the manure conveying plate 2 to prevent the manure conveying plate 2 from being deformed due to stress during operation due to its excessive length. Preferably, the support portion 17 is a U-shaped structure made of plastic, and the bottom of both sides thereof protrude outward to form mounting blocks 19. Mounting slots 20 for mounting the mounting blocks 19 are provided between the manure conveying plate 2 and the side walls of the manure conveying plate 2, which facilitate the installation and disassembly of the support portion 17 and the scraper 13, and provide convenience for subsequent inspection and maintenance. In addition, reinforcing ribs are provided at the position where the support wheel 18 is provided on the support portion 17 to ensure the structural strength of the support portion 17.

[0039] In addition, the two conveyor sprockets 34 on either side of one end of the frame 1 are both horizontally movable and adjustable. Specifically, a fixed plate 35 is provided at one end of the frame 1, with a guide rail 36 disposed at the bottom of the fixed plate 35. A slide 37 slides within the guide rail 36. A movable slot 38 is formed through the fixed plate 35. A rotating shaft connected to the conveyor sprockets 34 moves through the movable slot 38 and is connected to the slide 37 via a bearing. A horizontal drive member 39 is provided on the fixed plate 35 to drive the slide 37. The horizontal drive member 39 is used to drive the slide 37 along the guide rail 36, thereby tightening the conveyor chain 33. This avoids equipment failure caused by loose conveyor sprockets 34, ensuring long-term stable operation of the equipment and convenient and quick operation, saving time and effort.

[0040] The horizontal drive member 39 is preferably a hydraulic cylinder, one end of which is fixed to the fixed plate 35, and the movable section is connected to the slide 37. During operation, the hydraulic cylinder is controlled to extend and retract, driving the slide 37 to slide within the guide rail 36, thereby driving the conveyor sprocket 34 to move, thereby achieving tensioning of the conveyor chain 33. This is simple, quick, and highly practical. Furthermore, in this embodiment, a manual hydraulic pump station 40 is mounted on either side of the fixed plate 35. The oil outlet of the manual hydraulic pump station 40 is connected to the oil inlets of the two hydraulic cylinders via two oil inlet branch pipes. The oil inlet of the manual hydraulic pump is equipped with an oil return pipe equipped with a hand valve and a pressure gauge. The oil return pipe is connected to an energy storage tank via an energy storage pipe. The energy storage tank is mounted on the fixed plate 35 and can store pressure, the value of which can be intuitively read via a pressure gauge. The oil return main pipe is connected to the oil return ports of the two hydraulic cylinders through two oil return branch pipes. By operating the manual hydraulic pump, the synchronous operation of the two groups of hydraulic cylinders can be controlled to achieve rapid tensioning of the conveying chains 33 on both sides.

[0041] When the utility model is working, first, the feeding mechanism 3 conveys the received air-dried manure to the dry material lifting mechanism 4, and the dry material lifting mechanism 4 lifts a part of the air-dried manure to the dry material laying mechanism 6, and the dry material laying mechanism 6 evenly lays the dry manure on the top manure conveying plate 2, and the other part of the dry manure is discharged for use through the discharge channel 5 at the top; secondly, as the air-dried manure is spread, the top manure conveying plate 2 moves toward the wet material laying mechanism, and at this time the wet material laying mechanism evenly spreads the received wet material on the air-dried manure by reciprocating swinging; finally The upper layer of the manure conveying plate 2 with mixed dry and wet manure and sewage moves in the direction away from the dry material spreading mechanism until it moves to the end of the frame 1 and the manure and sewage on it falls onto the lower manure conveying plate 2. The lower manure conveying plate 2 conveys in the opposite direction, alternating in sequence until the manure and sewage are conveyed to the bottom manure conveying plate 2 and transported to the feeding mechanism 3. The dry material lifting mechanism 4 lifts and transports the air-dried manure and sewage. Part of the dry manure and sewage is lifted to the dry material laying mechanism 6 and spread on the top manure conveying plate 2 by the dry material laying mechanism 6. The other part of the dry manure and sewage is further lifted and output by the dry material lifting mechanism 4. The utility model uses dried manure and sewage to lay a bottom on the top manure conveying plate 2, which effectively avoids the manure and sewage adhering to the manure conveying plate 2 and being difficult to fall off due to the moisture of the mixed manure and sewage, and the clogging of the ventilation holes on the manure conveying plate 2, thereby ensuring the drying effect and drying efficiency of the manure and sewage. The dried manure and sewage can also be recycled during the output process, which is highly practical.
