Device and method for preparing fertilizer from garden waste

Abstract

The invention relates to the technical field of preparation of fertilizer from garden waste, in particular to a device and method for preparing fertilizer from garden waste, the device comprises a fermentation tank, a turning assembly, a spraying assembly, a feeding assembly and a crushing assembly, the turning assembly is arranged in the fermentation tank, and the turning assembly is matched with the feeding assembly for feeding; the crushed garden waste can be automatically and uniformly laid in the fermentation tank, and meanwhile, ingredients such as water, urea and a leavening agent are sprayed in cooperation with the spraying assembly, so that the ingredients and the crushed garden waste are more sufficiently and uniformly mixed together, and the comprehensiveness and thoroughness of fermentation of the device are further improved; meanwhile, in the fermentation process, the stirring assembly can stir the fermented garden waste, the oxygen content in fermentation substances is increased through stirring, and the fermentation substances are prevented from being overheated.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation from garden waste, in particular to a device and method for preparing fertilizer from garden waste. Background technique [0002] The preparation of chemical fertilizers from garden waste is to use grass clippings, branches and fallen bark in the garden green space, add other auxiliary materials, and use microorganisms to degrade them into organic substances under certain biological conditions. After fermentation, the organic perishable substances in the raw materials are transformed into organic nutrients or humus, and finally form compost products. The garden waste can be used as compost products and reused in the garden to serve the landscaping. During the compost fermentation process , needs a kind of device that utilizes garden waste to prepare fertilizer, and provides space for compost fermentation through this device. [0003] The Chinese patent with the application number C...

Problems solved by technology

[0003] The Chinese patent with the application number CN202010907030.6 discloses a garden waste compounding machine, which solves the problem that the existing garden waste is generally filled and rotted, and then returned to the field, which takes a long time to become Fertilizer is absorbed by plants, and the transfer of garden waste requires a lot of manpower and material resources, which is not suitable for modern production and life. The present invention includes a sieving device; There is a crushing device at the corresponding position at the lower end of the container, and the crushing device is connected with the fermentation tank; the sand and gravel in the garden waste are screened out through the screening device, and then the other heavy garbage is separated by the centrifugal device, and then passed through the crushing device The leaves and branches are crushed and ground to shorten the fermentation time of the fermentation tank. After fermentation, they can be used as fertilizers, etc. to achieve green environmental protection, and can also speed up fermentation to avoid discomfort to the human body in windy weather. The garden disclosed by this patent When the waste material machine is fermenting, the fermented material cannot be turned over, which will easily cause the internal overheating of the fermented material and the low internal oxygen content, which will affect the comprehensiveness of the fermentation, resulting in insufficient fermentation and decomposition, resulting in too much impurities in the fermented fertilizer

[0004] However, the existing devices for preparing fertilizers from garden wastes have great defects in the process of use. The existing devices for preparing fertilizers from garden wastes cannot fully mix the garden wastes, and cannot provide even and comprehensive fermented microorganisms. At the same time, the added auxiliary materials for fermentation cannot be fully and evenly dispersed, resulting in insufficient fermentation, and the fermented fertilizer has too many impurities and low quality. The existing device for preparing fertilizer from garden waste cannot Stirring of the fermented material will easily cause the internal overheating of the fermented material and the low internal oxygen content. The existing device for making fertilizer from garden waste has low fermentation efficiency, and the garden waste cannot be crushed in advance.
