Description

Technical Field

[0001] The utility model relates to the technical field of manure recycling, in particular to a rabbit manure recycling system. Background Art

[0002] Animal husbandry occupies an important position in the development of my country's agriculture and rural economy. "Clean production" and "waste resource utilization" are important issues in the development of animal husbandry today. In the process of large-scale rabbit breeding, a large amount of rabbit manure will be produced. Since rabbit manure contains a large number of bacteria, parasites, etc., it will inevitably cause serious environmental pollution if it is discharged directly into the environment without treatment. But at the same time, rabbit manure is also an organic fertilizer with extremely high nutrients. It is rich in nutrients such as crude protein, crude fat, fiber, vitamins and minerals. The carbon-nitrogen ratio (C / N) is 6.25. It can improve soil and improve the quality of agricultural products, and has promotion value. Urea, ammonia nitrogen, potassium, phosphorus, etc. in rabbit manure can be directly absorbed and utilized by plants, but the undigested and absorbed protein cannot be directly utilized by plants and needs to be fermented and decomposed before it can be absorbed. Therefore, the fertilization effect of rabbit manure directly used as fertilizer is not good, and rabbit manure needs to be processed to improve its fertilization effect.

[0003] The most common method of dealing with rabbit manure is composting. Mix rabbit manure and residual grass together, add water evenly, so that the ratio of water to rabbit manure and residual grass is 1:1. Pile it into a cylindrical shape and use cement to make a closed system for fermentation. After a period of time, the temperature inside can be higher than 50℃. After cooling for a period of time, open the closed system of the manure pile and let the manure pile continue to ferment until the manure becomes odorless or sour, the color turns brown, and it feels soft and non-sticky when touched by hand. Rabbit manure composting is complete.

[0004] When the rabbit manure organic fertilizer prepared by the existing fermentation method is applied to the cultivation of fruits, vegetables and rice seedlings, the seedlings will be burned and additional nutrients need to be added. Therefore, it is necessary to provide a new rabbit manure recycling system to improve the fertilization effect of rabbit manure and improve resource utilization. Utility Model Content

[0005] In order to solve the above problems in the prior art, the utility model provides a rabbit manure recycling system to effectively treat rabbit manure and reasonably recycle it, while improving the farm environment, reducing environmental pollution and improving resource utilization.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The rabbit manure recycling system of the utility model collects and recycles the rabbit manure generated during the rabbit house breeding process, which is beneficial to reducing environmental pollution. In the rabbit manure recycling system, the rabbit manure is first sterilized at high temperature by setting a heating tank, and then fermented twice in a primary fermentation tank and a secondary fermentation and drying area to make the rabbit manure fully decomposed.

[0023] like Figure 1 As shown, a rabbit manure recycling system comprises a rabbit house 1, a rabbit manure processing device and a rice seedling raising area 2. The rabbit manure from the rabbit house is recycled and processed by the rabbit manure processing device to be made into rabbit manure organic fertilizer, which is sent to the rice seedling raising area and can be used as a cultivation soil for rice seedlings; the rabbit manure processing device comprises a storage tank 3, a heating tank 4, a primary fermentation tank 5, a secondary fermentation and drying area 6 and a mixing tank 7 which are connected in sequence through pipelines; the rabbit manure outlet of the rabbit house 1 is connected to the feed inlet of the storage tank 3 through a pipeline; and the discharge port of the mixing tank 7 is connected to the rice seedling raising area 2 through a conveyor belt.

[0024] Furthermore, a plurality of rice seedling raising trays for filling with cultivation soil are arranged on the conveyor belt between the mixing tank 7 and the rice seedling raising area 2. The cultivation soil is a mixture of rabbit manure, organic fertilizer and soil in a ratio of 1:1. A spray device is arranged next to the conveyor belt for flushing the cultivation soil.

[0025] Furthermore, a mechanical arm (not shown) for transferring the rice seedling tray is also provided beside the conveyor belt. The cultivation tray after adding rice seeds can be transferred to the rice seedling raising area with constant temperature, pressure and humidity by the mechanical arm for raising seedlings (it can also be moved manually), which effectively improves the efficiency of raising seedlings.
