Description

Technical Field

[0001] The present invention relates to the technical field of manure air-drying equipment, and in particular to a novel manure air-drying equipment and a manure air-drying method. Background Art

[0002] In animal husbandry, if the manure produced by poultry is not processed in time, it will cause serious damage to the surrounding environment. Manure contains rich nutrients. If it can be air-dried and further processed, it will have high commercial value. At present, there are corresponding equipment for manure treatment, but due to factors such as region, climate, and economic benefits, a single manure treatment equipment cannot be fully applicable to all application scenarios, but different solutions need to be designed according to each application scenario.

[0003] The key to manure air-drying equipment is how to quickly, economically and reasonably reduce the moisture content in manure to the specified value. At present, in the application of manure air-drying equipment, a relatively economical and reasonable solution is that the air-drying heat source comes from the heat generated by the chickens in the chicken house, and the manure is air-dried through the exhaust fan at the rear of the chicken house; when laying materials, the current equipment mixes 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, and at the same time cause blockage of the manure board holes, thereby affecting the air-drying effect. Therefore, there is an urgent need for a new type of manure air-drying equipment and a manure air-drying method to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a new type of manure air-drying equipment and method, which can utilize the cooperation of a feeding mechanism, a dry material lifting mechanism and a dry material laying mechanism to first lay a layer of pre-dried manure on a manure board before laying wet manure, and then spread the wet manure, thereby effectively preventing manure from sticking to the manure board and blocking the ventilation holes, thereby improving the drying efficiency of manure.

[0005] The present invention adopts the following technical solutions: A novel manure drying device comprises a frame, on which a plurality of groups of manure conveying plates which are parallel and run in opposite directions are arranged at intervals; a feeding mechanism is arranged at the outlet end of the manure conveying plate on the bottom layer, and the output end of the feeding mechanism is connected with a dry material lifting mechanism, which is vertically arranged on one side of the frame; an upper and lower discharge channel is arranged on the dry material lifting mechanism, and the discharge channel on the lower layer is connected with a dry material laying mechanism, which is arranged above the manure conveying plate on the top layer; a wet material laying mechanism which can swing left and right is arranged on the frame on one side of the dry material laying mechanism.

[0009] Preferably, a material leveling paddle is provided on the top of the frame, and the material leveling paddle is located above the manure conveying plate on the top layer.

[0010] Preferably, a discharge port is provided at the bottom of the dry material laying mechanism, and a height-adjustable material level adjustment plate is provided on the side close to the wet material laying mechanism; a dry material detection sensor is provided at one end of the dry material laying mechanism away from the discharge channel.

[0013] Preferably, a fixed plate is provided at one end of the frame, a slide plate is slidably provided on the fixed plate, a rotating shaft connected to the conveying sprocket movably passes through the fixed plate and is connected to the slide plate; a linear driving member for driving the slide plate to move is provided on the fixed plate.

[0014] A novel air-drying method for manure and sewage, using the novel air-drying device for manure and sewage described above, comprises the following steps: S1 First, the feeding mechanism transports the received air-dried manure to the dry material lifting mechanism, which lifts part of the air-dried manure to the dry material laying mechanism, which evenly lays it on the manure conveying plate on the top layer, and the other part of the manure is discharged through the discharge channel at the top; S2 Secondly, as the air-dried manure is spread, the manure conveying plate on the top layer moves toward the wet material laying mechanism, and the wet material laying mechanism evenly spreads the received wet material on the air-dried manure by reciprocating swinging; S3 Finally, the manure conveying board with dry and wet mixed manure on the upper layer moves away from the dry material spreading mechanism until it moves to the end of the frame, and the manure on it falls onto the manure conveying board below, and the manure conveying board below conveys it in the opposite direction, alternating in sequence until the manure is transported to the bottom manure conveying board and then transported to the conveying mechanism, and the air-dried manure is lifted and transported by the dry material lifting mechanism.

The present invention uses air-dried feces as a base and spreads it on the upper feces conveying board 2, thereby avoiding direct contact between wet feces and the feces conveying board 2, and further preventing the wet feces from adhering to the feces conveying board 2 due to its high viscosity and being difficult to fall off and clogging the ventilation holes on the feces conveying board 2, thereby ensuring the air-drying efficiency and effect of the feces.

In addition, in this embodiment, a dry material detection sensor 9 is provided at one end of the dry material laying mechanism 6 away from the discharge channel 5. When the air-dried feces and sewage are transported from one end of the dry material laying mechanism 6 to the other end, the dry material detection sensor 9 detects the feces and sewage, and the dry material laying mechanism 6 stops working, and the manure conveying plate 2 starts to move, so as to ensure that the dry feces and sewage are evenly laid along the width direction of the manure conveying plate 2, and to prevent the situation where there is feces and sewage only on one side of the manure conveying plate 2 in the width direction.

At this time, the two hydraulic cylinders are allowed to operate, driving the material paving conveyor belt 24 to swing back and forth to ensure the uniformity of material paving. When there is no material on the material paving conveyor belt 24, the baffle 29 is reset, and at the same time, the rotating shaft and the eccentric wheel 31 are driven to rotate and reset.
